-
-From: Seunghun Han <kkamagui@gmail.com>
-
-[ Upstream commit 97f3c0a4b0579b646b6b10ae5a3d59f0441cc12c ]
-
-I found an ACPI cache leak in ACPI early termination and boot continuing case.
-
-When early termination occurs due to malicious ACPI table, Linux kernel
-terminates ACPI function and continues to boot process. While kernel terminates
-ACPI function, kmem_cache_destroy() reports Acpi-Operand cache leak.
-
-Boot log of ACPI operand cache leak is as follows:

-
-I analyzed this memory leak in detail and found acpi_ns_evaluate() function
-only removes Info->return_object in AE_CTRL_RETURN_VALUE case. But, when errors
-occur, the status value is not AE_CTRL_RETURN_VALUE, and Info->return_object is
-also not null. Therefore, this causes acpi operand memory leak.
-
-This cache leak causes a security threat because an old kernel (<= 4.9) shows
-memory locations of kernel functions in stack dump. Some malicious users
-could use this information to neutralize kernel ASLR.
-
-I made a patch to fix ACPI operand cache leak.

-

-
-[ Upstream commit 71426535f49fe6034d0e0db77608b91a0c1a022d ]
-
-Add native DSD support quirk for Luxman DA-06 DAC, by adding the
-PID/VID 1852:5065.
-
-Rename "is_marantz_denon_dac()" function to "is_itf_usb_dsd_2alts_dac()"
-to cover broader device family sharing the same USB audio
-implementation(*).
-For the same reason, rename "is_teac_dsd_dac()" function to
-"is_itf_usb_dsd_3alts_dac()".
-
-(*)
-These devices have the same USB controller "ITF-USB DSD", supplied by
-INTERFACE Co., Ltd.
-"ITF-USB DSD" USB controller has two patterns,
-
-Pattern 1. (2 altsets version)
-- Altset 0: for control
-- Altset 1: for stream (S32)
-- Altset 2: for stream (S32, DSD_U32)
-
-Pattern 2. (3 altsets version)
-- Altset 0: for control
-- Altset 1: for stream (S16)
-- Altset 2: for stream (S32)
-- Altset 3: for stream (S32, DSD_U32)
-
-"is_itf_usb_dsd_2alts_dac()" returns true, if the DAC has "Pattern 1"
-USB controller, and "is_itf_usb_dsd_3alts_dac()" returns true, if
-"Pattern2".

-Subject: ARC: mcip: halt GFRC counter when ARC cores halt
-
-From: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com>
-
-[ Upstream commit 07423d00a2b2a71a97e4287d9262cb83c4c4c89f ]
-
-In SMP systems, GFRC is used for clocksource. However by default the
-counter keeps running even when core is halted (say when debugging via a
-JTAG debugger). This confuses Linux timekeeping and triggers flase RCU stall
-splat such as below:
-
-| [ARCLinux]# while true; do ./shm_open_23-1.run-test ; done
-| Running with 1000 processes for 1000 objects
-| hrtimer: interrupt took 485060 ns
-|
-| create_cnt: 1000
-| Running with 1000 processes for 1000 objects
-| [ARCLinux]# INFO: rcu_preempt self-detected stall on CPU
-| 2-...: (1 GPs behind) idle=a01/1/0 softirq=135770/135773 fqs=0
-| INFO: rcu_preempt detected stalls on CPUs/tasks:
-| 0-...: (1 GPs behind) idle=71e/0/0 softirq=135264/135264 fqs=0
-| 2-...: (1 GPs behind) idle=a01/1/0 softirq=135770/135773 fqs=0
-| 3-...: (1 GPs behind) idle=4e0/0/0 softirq=134304/134304 fqs=0
-| (detected by 1, t=13648 jiffies, g=31493, c=31492, q=1)
-
-Starting from ARC HS v3.0 it's possible to tie GFRC to state of up-to 4
-ARC cores with help of GFRC's CORE register where we set a mask for
-cores which state we need to rely on.
-
-We update cpu mask every time new cpu came online instead of using
-hardcoded one or using mask generated from "possible_cpus" as we
-want it set correctly even if we run kernel on HW which has fewer cores
-than expected (or we launch kernel via debugger and kick fever cores
-than HW has)
-
-Note that GFRC halts when all cores have halted and thus relies on
-programming of Inter-Core-dEbug register to halt all cores when one
-halts.

-
-[ Upstream commit a29a25275452c97fe35815f1eb9564f2a07a1965 ]

-
-From: Jinbum Park <jinb.park7@gmail.com>
-
-[ Upstream commit 73b9160d0dfe44dfdaffd6465dc1224c38a4a73c ]
-
-Define vdso_start, vdso_end as array to avoid compile-time analysis error
-for the case of built with CONFIG_FORTIFY_SOURCE.
-
-and, since vdso_start, vdso_end are used in vdso.c only,
-move extern-declaration from vdso.h to vdso.c.
-
-If kernel is built with CONFIG_FORTIFY_SOURCE,
-compile-time error happens at this code.
-- if (memcmp(&vdso_start, "177ELF", 4))
-
-The size of "&vdso_start" is recognized as 1 byte, but n is 4,
-So that compile-time error is reported.

-
-[ Upstream commit 5571196135abb6d51e01592812997403c136067c ]
-
-The current (mildly evil) fsl_pq_mdio code uses an undocumented shadow of
-the TBIPA register on LS1021A, which happens to be read-only.
-Changing TBI PHY address therefore does not work on LS1021A.
-
-The real (and documented) address of the TBIPA registere lies in the eTSEC
-block and not in MDIO/MII, which is read/write, so using that fixes
-the problem.

-
-Trying to boot an RK3328 box with an HS200-capable eMMC, I see said eMMC
-fail to initialise as it can't run its tuning procedure, because the
-sample clock is missing. Upon closer inspection, whilst the clock is
-present in the DT, its name is subtly incorrect per the binding, so
-__of_clk_get_by_name() never finds it. By inspection, the drive clock
-suffers from a similar problem, so has never worked properly either.
-
-This error has propagated across the 32-bit DTs too, so fix those up.

-
-When exposing data access through debugfs, the correct

-
-Remove all casts from data pointers passed to debugfs_create_*()
-functions, as such casts prevent the compiler from flagging bugs.
-
-Correct all wrong usage:
- - clk.rate is unsigned long, not u32,
- - clk.flags is u8, not u32, which exposed the successive
- clk.rate_offset and clk.src_offset fields.

-

-
-HS omaps use irq_save_secure_context() instead of irq_save_context()
-so sar_base will never get initialized and irq_sar_clear() gets called
-with a wrong address for HS omaps from irq_restore_context().
-
-Starting with commit f4b9f40ae95b ("ARM: OMAP4+: Initialize SAR RAM
-base early for proper CPU1 reset for kexec") we have it available,
-and this ideally would been fixed with that commit already.

-
-From: Qi Hou <qi.hou@windriver.com>
-
-[ Upstream commit db35340c536f1af0108ec9a0b2126a05d358d14a ]
-
-When more than one GP timers are used as kernel system timers and the
-corresponding nodes in device-tree are marked with the same "disabled"
-property, then the "attr" field of the property will be initialized
-more than once as the property being added to sys file system via
-__of_add_property_sysfs().
-
-In __of_add_property_sysfs(), the "name" field of pp->attr.attr is set
-directly to the return value of safe_name(), without taking care of
-whether it's already a valid pointer to a memory block. If it is, its
-old value will always be overwritten by the new one and the memory block
-allocated before will a "ghost", then a kmemleak happened.
-
-That the same "disabled" property being added to different nodes of device
-tree would cause that kind of kmemleak overhead, at least once.
-
-To fix it, allocate the property dynamically, and delete static one.

-Subject: ARM: OMAP3: Fix prm wake interrupt for resume
-
-From: Tony Lindgren <tony@atomide.com>
-
-[ Upstream commit d3be6d2a08bd26580562d9714d3d97ea9ba22c73 ]
-
-For platform_suspend_ops, the finish call is too late to re-enable wake
-irqs and we need re-enable wake irqs on wake call instead.
-
-Otherwise noirq resume for devices has already happened. And then
-dev_pm_disarm_wake_irq() has already disabled the dedicated wake irqs
-when the interrupt triggers and the wake irq is never handled.
-
-For devices that are already in PM runtime suspended state when we
-enter suspend this means that a possible wake irq will never trigger.
-
-And this can lead into a situation where a device has a pending padconf
-wake irq, and the device will stay unresponsive to any further wake
-irqs.
-
-This issue can be easily reproduced by setting serial console log level
-to zero, letting the serial console idle, and suspend the system from
-an ssh terminal. Then try to wake up the system by typing to the serial
-console.
-
-Note that this affects only omap3 PRM interrupt as that's currently
-the only omap variant that does anything in omap_pm_wake().
-
-In general, for the wake irqs to work, the interrupt must have either
-IRQF_NO_SUSPEND or IRQF_EARLY_RESUME set for it to trigger before
-dev_pm_disarm_wake_irq() disables the wake irqs.

-
-It is not valid for orion5x to use mac_pton().
-
-First of all, the orion5x buffer is not NULL terminated. mac_pton()
-has no business operating on non-NULL terminated buffers because
-only the caller can know that this is valid and in what manner it
-is ok to parse this NULL'less buffer.
-
-Second of all, orion5x operates on an __iomem pointer, which cannot
-be dereferenced using normal C pointer operations. Accesses to
-such areas much be performed with the proper iomem accessors.

-
-Trying to boot an RK3328 box with an HS200-capable eMMC, I see said eMMC
-fail to initialise as it can't run its tuning procedure, because the
-sample clock is missing. Upon closer inspection, whilst the clock is
-present in the DT, its name is subtly incorrect per the binding, so
-__of_clk_get_by_name() never finds it. By inspection, the drive clock
-suffers from a similar problem, so has never worked properly either.
-
-Fix up all instances of the incorrect clock names across the 64-bit DTs.

-Subject: arm64: dts: rockchip: Fix rk3399-gru-* s2r (pinctrl hogs, wifi reset)
-
-From: Douglas Anderson <dianders@chromium.org>
-
-[ Upstream commit 2560da49de5d0cfec22e9564023aebfffa094732 ]
-
-Back in the early days when gru devices were still under development
-we found an issue where the WiFi reset line needed to be configured as
-early as possible during the boot process to avoid the WiFi module
-being in a bad state.
-
-We found that the way to get the kernel to do this in the earliest
-possible place was to configure this line in the pinctrl hogs, so
-that's what we did. For some history here you can see
-<http://crosreview.com/368770>. After the time that change landed in
-the kernel, we landed a firmware change to configure this line even
-earlier. See <http://crosreview.com/399919>. However, even after the
-firmware change landed we kept the kernel change to deal with the fact
-that some people working on devices might take a little while to
-update their firmware.
-
-At this there are definitely zero devices out in the wild that have
-firmware without the fix in it. Specifically looking in the firmware
-branch several critically important fixes for memory stability landed
-after the patch in coreboot and I know we didn't ship without those.
-Thus, by now, everyone should have the new firmware and it's safe to
-not have the kernel set this up in a pinctrl hog.
-
-Historically, even though it wasn't needed to have this in a pinctrl
-hog, we still kept it since it didn't hurt. Pinctrl would apply the
-default hog at bootup and then would never touch things again. That
-all changed with commit 981ed1bfbc6c ("pinctrl: Really force states
-during suspend/resume"). After that commit then we'll re-apply the
-default hog at resume time and that can screw up the reset state of
-WiFi. ...and on rk3399 if you touch a device on PCIe in the wrong way
-then the whole system can go haywire. That's what was happening.
-Specifically you'd resume a rk3399-gru-* device and it would mostly
-resume, then would crash with some crazy weird crash.
-
-One could say, perhaps, that the recent pinctrl change was at fault
-(and should be fixed) since it changed behavior. ...but that's not
-really true. The device tree for rk3399-gru is really to blame.
-Specifically since the pinctrl is defined in the hog and not in the
-"wlan-pd-n" node then the actual user of this pin doesn't have a
-pinctrl entry for it. That's bad.
-
-Let's fix our problems by just moving the control of
-"wlan_module_reset_l pinctrl" out of the hog and put them in the
-proper place.
-
-NOTE: in theory, I think it should actually be possible to have a pin
-controlled _both_ by the hog and by an actual device. Once the device
-claims the pin I think the hog is supposed to let go. I'm not 100%
-sure that this works and in any case this solution would be more
-complex than is necessary.

-This commit enables thresh dma mode as this forces to disable checksuming,
-and chooses delay values which make the interface stable.

-These changes are needed, because ROCK64 is faced with two problems:
-1. tx checksuming does not work with packets larger than 1498,
-2. the default delays for tx/rx are not stable when using 1Gbps connection.

-Subject: arm64: fix unwind_frame() for filtered out fn for function graph tracing
-
-From: Pratyush Anand <panand@redhat.com>
-
-[ Upstream commit 9f416319f40cd857d2bb517630e5855a905ef3fb ]
-
-do_task_stat() calls get_wchan(), which further does unwind_frame().
-unwind_frame() restores frame->pc to original value in case function
-graph tracer has modified a return address (LR) in a stack frame to hook
-a function return. However, if function graph tracer has hit a filtered
-function, then we can't unwind it as ftrace_push_return_trace() has
-biased the index(frame->graph) with a 'huge negative'
-offset(-FTRACE_NOTRACE_DEPTH).
-
-Moreover, arm64 stack walker defines index(frame->graph) as unsigned
-int, which can not compare a -ve number.
-
-Similar problem we can have with calling of walk_stackframe() from
-save_stack_trace_tsk() or dump_backtrace().
-
-This patch fixes unwind_frame() to test the index for -ve value and
-restore index accordingly before we can restore frame->pc.
-
-Reproducer:
-
-cd /sys/kernel/debug/tracing/
-echo schedule > set_graph_notrace
-echo 1 > options/display-graph
-echo wakeup > current_tracer
-ps -ef | grep -i agent
-
-Above commands result in:

-Subject: arm64: insn: Allow ADD/SUB (immediate) with LSL #12
-
-From: Marc Zyngier <marc.zyngier@arm.com>
-
-[ Upstream commit 11d764079c9f25d1da8e10906d54da7fefec5844 ]
-
-The encoder for ADD/SUB (immediate) can only cope with 12bit
-immediates, while there is an encoding for a 12bit immediate shifted
-by 12 bits to the left.
-
-Let's fix this small oversight by allowing the LSL_12 bit to be set.

-
-From: Mark Rutland <mark.rutland@arm.com>
-
-[ Upstream commit 0331365edb1d6ccd6ae68b1038111da85d4c68d1 ]
-
-The ID_AA64DFR0_EL1.PMUVer field doesn't follow the usual ID registers
-scheme. While value 0xf indicates a non-architected PMU is implemented,
-values 0x1 to 0xe indicate an increasingly featureful architected PMU,
-as if the field were unsigned.
-
-For more details, see ARM DDI 0487C.a, D10.1.4, "Alternative ID scheme
-used for the Performance Monitors Extension version".
-
-Currently, we treat the field as signed, and erroneously bail out for
-values 0x8 to 0xe. Let's correct that.

-Subject: ath10k: Fix kernel panic while using worker (ath10k_sta_rc_update_wk)
-
-From: Karthikeyan Periyasamy <periyasa@codeaurora.org>
-
-[ Upstream commit 8b2d93dd22615cb7f3046a5a2083a6f8bb8052ed ]
-
-When attempt to run worker (ath10k_sta_rc_update_wk) after the station object
-(ieee80211_sta) delete will trigger the kernel panic.
-
-This problem arise in AP + Mesh configuration, Where the current node AP VAP
-and neighbor node mesh VAP MAC address are same. When the current mesh node
-try to establish the mesh link with neighbor node, driver peer creation for
-the neighbor mesh node fails due to duplication MAC address. Already the AP
-VAP created with same MAC address.
-
-It is caused by the following scenario steps.
-
-Steps:
-1. In above condition, ath10k driver sta_state callback (ath10k_sta_state)
- fails to do the state change for a station from IEEE80211_STA_NOTEXIST
- to IEEE80211_STA_NONE due to peer creation fails. Sta_state callback is
- called from ieee80211_add_station() to handle the new station
- (neighbor mesh node) request from the wpa_supplicant.
-2. Concurrently ath10k receive the sta_rc_update callback notification from
- the mesh_neighbour_update() to handle the beacon frames of the above
- neighbor mesh node. since its atomic callback, ath10k driver queue the
- work (ath10k_sta_rc_update_wk) to handle rc update.
-3. Due to driver sta_state callback fails (step 1), mac80211 free the station
- object.
-4. When the worker (ath10k_sta_rc_update_wk) scheduled to run, it will access
- the station object which is already deleted. so it will trigger kernel
- panic.
-
-Added the peer exist check in sta_rc_update callback before queue the work.
-
-Kernel Panic log:
-

-
-From: Richard Guy Briggs <rgb@redhat.com>
-
-[ Upstream commit 23138ead270045f1b3e912e667967b6094244999 ]
-
-If there is a memory allocation error when trying to change an audit
-kernel feature value, the ignored allocation error will trigger a NULL
-pointer dereference oops on subsequent use of that pointer. Return
-instead.
-
-Passes audit-testsuite.

-
-From: "Linus Lüssing" <linus.luessing@c0d3.blue>
-
-[ Upstream commit 74c12c630fe310eb7fcae1b292257d47781fff0a ]
-
-As the kernel doc describes too the code is supposed to skip adding
-multicast TT entries if both the WANT_ALL_IPV4 and WANT_ALL_IPV6 flags
-are present.
-
-Unfortunately, the current code even skips adding multicast TT entries
-if only either the WANT_ALL_IPV4 or WANT_ALL_IPV6 is present.
-
-This could lead to IPv6 multicast packet loss if only an IGMP but not an
-MLD querier is present for instance or vice versa.

-Subject: batman-adv: fix multicast-via-unicast transmission with AP isolation
-
-From: "Linus Lüssing" <linus.luessing@c0d3.blue>
-
-[ Upstream commit f8fb3419ead44f9a3136995acd24e35da4525177 ]
-
-For multicast frames AP isolation is only supposed to be checked on
-the receiving nodes and never on the originating one.
-
-Furthermore, the isolation or wifi flag bits should only be intepreted
-as such for unicast and never multicast TT entries.
-
-By injecting flags to the multicast TT entry claimed by a single
-target node it was verified in tests that this multicast address
-becomes unreachable, leading to packet loss.
-
-Omitting the "src" parameter to the batadv_transtable_search() call
-successfully skipped the AP isolation check and made the target
-reachable again.

-Subject: batman-adv: fix packet checksum in receive path
-
-From: Matthias Schiffer <mschiffer@universe-factory.net>
-
-[ Upstream commit abd6360591d3f8259f41c34e31ac4826dfe621b8 ]
-
-eth_type_trans() internally calls skb_pull(), which does not adjust the
-skb checksum; skb_postpull_rcsum() is necessary to avoid log spam of the
-form "bat0: hw csum failure" when packets with CHECKSUM_COMPLETE are
-received.
-
-Note that in usual setups, packets don't reach batman-adv with
-CHECKSUM_COMPLETE (I assume NICs bail out of checksumming when they see
-batadv's ethtype?), which is why the log messages do not occur on every
-system using batman-adv. I could reproduce this issue by stacking
-batman-adv on top of a VXLAN interface.

-Subject: batman-adv: fix packet loss for broadcasted DHCP packets to a server
-
-From: "Linus Lüssing" <linus.luessing@c0d3.blue>
-
-[ Upstream commit a752c0a4524889cdc0765925258fd1fd72344100 ]
-
-DHCP connectivity issues can currently occur if the following conditions
-are met:
-
-1) A DHCP packet from a client to a server
-2) This packet has a multicast destination
-3) This destination has a matching entry in the translation table
- (FF:FF:FF:FF:FF:FF for IPv4, 33:33:00:01:00:02/33:33:00:01:00:03
- for IPv6)
-4) The orig-node determined by TT for the multicast destination
- does not match the orig-node determined by best-gateway-selection
-
-In this case the DHCP packet will be dropped.
-
-The "gateway-out-of-range" check is supposed to only be applied to
-unicasted DHCP packets to a specific DHCP server.
-
-In that case dropping the the unicasted frame forces the client to
-retry via a broadcasted one, but now directed to the new best
-gateway.
-
-A DHCP packet with broadcast/multicast destination is already ensured to
-always be delivered to the best gateway. Dropping a multicasted
-DHCP packet here will only prevent completing DHCP as there is no
-other fallback.
-
-So far, it seems the unicast check was implicitly performed by
-expecting the batadv_transtable_search() to return NULL for multicast
-destinations. However, a multicast address could have always ended up in
-the translation table and in fact is now common.
-
-To fix this potential loss of a DHCP client-to-server packet to a
-multicast address this patch adds an explicit multicast destination
-check to reliably bail out of the gateway-out-of-range check for such
-destinations.
-
-The issue and fix were tested in the following three node setup:
-
-- Line topology, A-B-C
-- A: gateway client, DHCP client
-- B: gateway server, hop-penalty increased: 30->60, DHCP server
-- C: gateway server, code modifications to announce FF:FF:FF:FF:FF:FF
-
-Without this patch, A would never transmit its DHCP Discover packet
-due to an always "out-of-range" condition. With this patch,
-a full DHCP handshake between A and B was possible again.

-Subject: batman-adv: invalidate checksum on fragment reassembly
-
-From: Matthias Schiffer <mschiffer@universe-factory.net>
-
-[ Upstream commit 3bf2a09da956b43ecfaa630a2ef9a477f991a46a ]
-
-A more sophisticated implementation could try to combine fragment checksums
-when all fragments have CHECKSUM_COMPLETE and are split at even offsets.
-For now, we just set ip_summed to CHECKSUM_NONE to avoid "hw csum failure"
-warnings in the kernel log when fragmented frames are received. In
-consequence, skb_pull_rcsum() can be replaced with skb_pull().
-
-Note that in usual setups, packets don't reach batman-adv with
-CHECKSUM_COMPLETE (I assume NICs bail out of checksumming when they see
-batadv's ethtype?), which is why the log messages do not occur on every
-system using batman-adv. I could reproduce this issue by stacking
-batman-adv on top of a VXLAN interface.

-All the crash issue happened when a bypass IO coming, in such scenario
-s->iop.bio is pointed to the s->orig_bio. In search_free(), it finishes the
-s->orig_bio by calling bio_complete(), and after that, s->iop.bio became
-invalid, then kernel would crash when calling bio_put(). Maybe its upper
-layer's faulty, since bio should not be freed before we calling bio_put(),
-but we'd better calling bio_put() first before calling bio_complete() to
-notify upper layer ending this bio.
-
-This patch moves bio_complete() under bio_put() to avoid kernel crash.

-Subject: bcache: quit dc->writeback_thread when BCACHE_DEV_DETACHING is set
-
-From: Coly Li <colyli@suse.de>
-
-[ Upstream commit fadd94e05c02afec7b70b0b14915624f1782f578 ]
-
-In patch "bcache: fix cached_dev->count usage for bch_cache_set_error()",
-cached_dev_get() is called when creating dc->writeback_thread, and
-cached_dev_put() is called when exiting dc->writeback_thread. This
-modification works well unless people detach the bcache device manually by
- 'echo 1 > /sys/block/bcache<N>/bcache/detach'
-Because this sysfs interface only calls bch_cached_dev_detach() which wakes
-up dc->writeback_thread but does not stop it. The reason is, before patch
-"bcache: fix cached_dev->count usage for bch_cache_set_error()", inside
-bch_writeback_thread(), if cache is not dirty after writeback,
-cached_dev_put() will be called here. And in cached_dev_make_request() when
-a new write request makes cache from clean to dirty, cached_dev_get() will
-be called there. Since we don't operate dc->count in these locations,
-refcount d->count cannot be dropped after cache becomes clean, and
-cached_dev_detach_finish() won't be called to detach bcache device.
-
-This patch fixes the issue by checking whether BCACHE_DEV_DETACHING is
-set inside bch_writeback_thread(). If this bit is set and cache is clean
-(no existing writeback_keys), break the while-loop, call cached_dev_put()
-and quit the writeback thread.
-
-Please note if cache is still dirty, even BCACHE_DEV_DETACHING is set the
-writeback thread should continue to perform writeback, this is the original
-design of manually detach.
-
-It is safe to do the following check without locking, let me explain why,
-+ if (!test_bit(BCACHE_DEV_DETACHING, &dc->disk.flags) &&
-+ (!atomic_read(&dc->has_dirty) || !dc->writeback_running)) {
-
-If the kenrel thread does not sleep and continue to run due to conditions
-are not updated in time on the running CPU core, it just consumes more CPU
-cycles and has no hurt. This should-sleep-but-run is safe here. We just
-focus on the should-run-but-sleep condition, which means the writeback
-thread goes to sleep in mistake while it should continue to run.
-1, First of all, no matter the writeback thread is hung or not,
- kthread_stop() from cached_dev_detach_finish() will wake up it and
- terminate by making kthread_should_stop() return true. And in normal
- run time, bit on index BCACHE_DEV_DETACHING is always cleared, the
- condition
- !test_bit(BCACHE_DEV_DETACHING, &dc->disk.flags)
- is always true and can be ignored as constant value.
-2, If one of the following conditions is true, the writeback thread should
- go to sleep,
- "!atomic_read(&dc->has_dirty)" or "!dc->writeback_running)"
- each of them independently controls the writeback thread should sleep or
- not, let's analyse them one by one.
-2.1 condition "!atomic_read(&dc->has_dirty)"
- If dc->has_dirty is set from 0 to 1 on another CPU core, bcache will
- call bch_writeback_queue() immediately or call bch_writeback_add() which
- indirectly calls bch_writeback_queue() too. In bch_writeback_queue(),
- wake_up_process(dc->writeback_thread) is called. It sets writeback
- thread's task state to TASK_RUNNING and following an implicit memory
- barrier, then tries to wake up the writeback thread.
- In writeback thread, its task state is set to TASK_INTERRUPTIBLE before
- doing the condition check. If other CPU core sets the TASK_RUNNING state
- after writeback thread setting TASK_INTERRUPTIBLE, the writeback thread
- will be scheduled to run very soon because its state is not
- TASK_INTERRUPTIBLE. If other CPU core sets the TASK_RUNNING state before
- writeback thread setting TASK_INTERRUPTIBLE, the implict memory barrier
- of wake_up_process() will make sure modification of dc->has_dirty on
- other CPU core is updated and observed on the CPU core of writeback
- thread. Therefore the condition check will correctly be false, and
- continue writeback code without sleeping.
-2.2 condition "!dc->writeback_running)"
- dc->writeback_running can be changed via sysfs file, every time it is
- modified, a following bch_writeback_queue() is alwasy called. So the
- change is always observed on the CPU core of writeback thread. If
- dc->writeback_running is changed from 0 to 1 on other CPU core, this
- condition check will observe the modification and allow writeback
- thread to continue to run without sleeping.
-Now we can see, even without a locking protection, multiple conditions
-check is safe here, no deadlock or process hang up will happen.
-
-I compose a separte patch because that patch "bcache: fix cached_dev->count
-usage for bch_cache_set_error()" already gets a "Reviewed-by:" from Hannes
-Reinecke. Also this fix is not trivial and good for a separate patch.

-Subject: Btrfs: clean up resources during umount after trans is aborted
-
-From: Liu Bo <bo.liu@linux.alibaba.com>
-
-[ Upstream commit af7227338135d2f1b1552bf9a6d43e02dcba10b9 ]
-
-Currently if some fatal errors occur, like all IO get -EIO, resources
-would be cleaned up when
-a) transaction is being committed or
-b) BTRFS_FS_STATE_ERROR is set
-
-However, in some rare cases, resources may be left alone after transaction
-gets aborted and umount may run into some ASSERT(), e.g.
-ASSERT(list_empty(&block_group->dirty_list));
-
-For case a), in btrfs_commit_transaciton(), there're several places at the
-beginning where we just call btrfs_end_transaction() without cleaning up
-resources. For case b), it is possible that the trans handle doesn't have
-any dirty stuff, then only trans hanlde is marked as aborted while
-BTRFS_FS_STATE_ERROR is not set, so resources remain in memory.
-
-This makes btrfs also check BTRFS_FS_STATE_TRANS_ABORTED to make sure that
-all resources won't stay in memory after umount.

-Subject: Btrfs: fix copy_items() return value when logging an inode
-
-From: Filipe Manana <fdmanana@suse.com>
-
-[ Upstream commit 8434ec46c6e3232cebc25a910363b29f5c617820 ]
-
-When logging an inode, at tree-log.c:copy_items(), if we call
-btrfs_next_leaf() at the loop which checks for the need to log holes, we
-need to make sure copy_items() returns the value 1 to its caller and
-not 0 (on success). This is because the path the caller passed was
-released and is now different from what is was before, and the caller
-expects a return value of 0 to mean both success and that the path
-has not changed, while a return value of 1 means both success and
-signals the caller that it can not reuse the path, it has to perform
-another tree search.
-
-Even though this is a case that should not be triggered on normal
-circumstances or very rare at least, its consequences can be very
-unpredictable (especially when replaying a log tree).

-
-This is the important bit:

-
-The percpu_counter_init call in btrfs_alloc_subvolume_writers

-Subject: Btrfs: fix log replay failure after linking special file and fsync
-
-From: Filipe Manana <fdmanana@suse.com>
-
-[ Upstream commit 9a6509c4daa91400b52a5fd541a5521c649a8fea ]
-
-If in the same transaction we rename a special file (fifo, character/block
-device or symbolic link), create a hard link for it having its old name
-then sync the log, we will end up with a log that can not be replayed and
-at when attempting to replay it, an EEXIST error is returned and mounting
-the filesystem fails. Example scenario:
-
- $ mkfs.btrfs -f /dev/sdc
- $ mount /dev/sdc /mnt
- $ mkdir /mnt/testdir
- $ mkfifo /mnt/testdir/foo
- # Make sure everything done so far is durably persisted.

-This happens because when both the log tree and the subvolume's tree have
-an entry in the directory "testdir" with the same name, that is, there
-is one key (258 INODE_REF 257) in the subvolume tree and another one in
-the log tree (where 258 is the inode number of our special file and 257
-is the inode for directory "testdir"). Only the data of those two keys
-differs, in the subvolume tree the index field for inode reference has
-a value of 3 while the log tree it has a value of 5. Because the same key
-exists in both trees, but have different index, the log replay fails with
-an -EEXIST error when attempting to replay the inode reference from the
-log tree.
-
-Fix this by setting the last_unlink_trans field of the inode (our special
-file) to the current transaction id when a hard link is created, as this
-forces logging the parent directory inode, solving the conflict at log
-replay time.
-
-A new generic test case for fstests was also submitted.

-Subject: Btrfs: fix loss of prealloc extents past i_size after fsync log replay
-
-From: Filipe Manana <fdmanana@suse.com>
-
-[ Upstream commit 471d557afed155b85da237ec46c549f443eeb5de ]
-
-Currently if we allocate extents beyond an inode's i_size (through the
-fallocate system call) and then fsync the file, we log the extents but
-after a power failure we replay them and then immediately drop them.
-This behaviour happens since about 2009, commit c71bf099abdd ("Btrfs:
-Avoid orphan inodes cleanup while replaying log"), because it marks
-the inode as an orphan instead of dropping any extents beyond i_size
-before replaying logged extents, so after the log replay, and while
-the mount operation is still ongoing, we find the inode marked as an
-orphan and then perform a truncation (drop extents beyond the inode's
-i_size). Because the processing of orphan inodes is still done
-right after replaying the log and before the mount operation finishes,
-the intention of that commit does not make any sense (at least as
-of today). However reverting that behaviour is not enough, because
-we can not simply discard all extents beyond i_size and then replay
-logged extents, because we risk dropping extents beyond i_size created
-in past transactions, for example:
-
- add prealloc extent beyond i_size
- fsync - clears the flag BTRFS_INODE_NEEDS_FULL_SYNC from the inode
- transaction commit
- add another prealloc extent beyond i_size
- fsync - triggers the fast fsync path
- power failure
-
-In that scenario, we would drop the first extent and then replay the
-second one. To fix this just make sure that all prealloc extents
-beyond i_size are logged, and if we find too many (which is far from
-a common case), fallback to a full transaction commit (like we do when
-logging regular extents in the fast fsync path).
-
-Trivial reproducer:
-
- $ mkfs.btrfs -f /dev/sdb
- $ mount /dev/sdb /mnt
- $ xfs_io -f -c "pwrite -S 0xab 0 256K" /mnt/foo
- $ sync
- $ xfs_io -c "falloc -k 256K 1M" /mnt/foo
- $ xfs_io -c "fsync" /mnt/foo
- <power failure>
-
- # mount to replay log
- $ mount /dev/sdb /mnt
- # at this point the file only has one extent, at offset 0, size 256K
-
-A test case for fstests follows soon, covering multiple scenarios that
-involve adding prealloc extents with previous shrinking truncates and
-without such truncates.

-
-From: Qu Wenruo <wqu@suse.com>
-
-[ Upstream commit 4d31778aa2fa342f5f92ca4025b293a1729161d1 ]
-
-When multiple pending snapshots referring to the same source subvolume
-are executed, enabled quota will cause root item corruption, where root
-items are using old bytenr (no backref in extent tree).
-
-This can be triggered by fstests btrfs/152.
-
-The cause is when source subvolume is still dirty, extra commit
-(simplied transaction commit) of qgroup_account_snapshot() can skip
-dirty roots not recorded in current transaction, making root item of
-source subvolume not updated.
-
-Fix it by forcing recording source subvolume in current transaction
-before qgroup sub-transaction commit.

-
-Looking at functions with large stack frames across all architectures
-led me discovering that BUG() suffers from the same problem as
-fortify_panic(), which I've added a workaround for already.
-
-In short, variables that go out of scope by calling a noreturn function
-or __builtin_unreachable() keep using stack space in functions
-afterwards.
-
-A workaround that was identified is to insert an empty assembler
-statement just before calling the function that doesn't return. I'm
-adding a macro "barrier_before_unreachable()" to document this, and
-insert calls to that in all instances of BUG() that currently suffer
-from this problem.
-
-The files that saw the largest change from this had these frame sizes
-before, and much less with my patch:

-In case of ARC and CRIS, it turns out that the BUG() implementation
-actually does return (or at least the compiler thinks it does),
-resulting in lots of warnings about uninitialized variable use and
-leaving noreturn functions, such as:
-
- block/cfq-iosched.c: In function 'cfq_async_queue_prio':
- block/cfq-iosched.c:3804:1: error: control reaches end of non-void function [-Werror=return-type]
- include/linux/dmaengine.h: In function 'dma_maxpq':
- include/linux/dmaengine.h:1123:1: error: control reaches end of non-void function [-Werror=return-type]
-
-This makes them call __builtin_trap() instead, which should normally
-dump the stack and kill the current process, like some of the other
-architectures already do.
-
-I tried adding barrier_before_unreachable() to panic() and
-fortify_panic() as well, but that had very little effect, so I'm not
-submitting that patch.
-
-Vineet said:
-
-: For ARC, it is double win.
-:
-: 1. Fixes 3 -Wreturn-type warnings
-:
-: | ../net/core/ethtool.c:311:1: warning: control reaches end of non-void function
-: [-Wreturn-type]
-: | ../kernel/sched/core.c:3246:1: warning: control reaches end of non-void function
-: [-Wreturn-type]
-: | ../include/linux/sunrpc/svc_xprt.h:180:1: warning: control reaches end of
-: non-void function [-Wreturn-type]
-:
-: 2. bloat-o-meter reports code size improvements as gcc elides the
-: generated code for stack return.

-This task tried to open the cdrom device, the sr_block_open function
-acquired the global sr_mutex lock. The call to check_disk_change()
-then saw an event flag indicating a possible media change and tried
-to flush any cached data for the device.
-As part of the flush, it tried to acquire the super_block->s_umount
-lock associated with the cdrom device.
-This was the same super_block as created and locked by the previous task.
-
-The first task acquires the s_umount lock and then the sr_mutex_lock;
-the second task acquires the sr_mutex_lock and then the s_umount lock.
-
-This patch fixes the issue by moving check_disk_change() out of
-cdrom_open() and let the caller take care of it.

-Subject: clk: Don't show the incorrect clock phase
-
-From: Shawn Lin <shawn.lin@rock-chips.com>
-
-[ Upstream commit 1f9c63e8de3d7b377c9d74e4a17524cfb60e6384 ]
-
-It's found that the clock phase output from clk_summary is
-wrong compared to the actual phase reading from the register.
-
-cat /sys/kernel/debug/clk/clk_summary | grep sdio_sample
-sdio_sample 0 1 0 50000000 0 -22
-
-It exposes an issue that clk core, clk_core_get_phase, always
-returns the cached core->phase which should be either updated
-by calling clk_set_phase or directly from the first place the
-clk was registered.
-
-When registering the clk, the core->phase geting from ->get_phase()
-may return negative value indicating error. This is quite common
-since the clk's phase may be highly related to its parent chain,
-but it was temporarily orphan when registered, since its parent
-chains hadn't be ready at that time, so the clk drivers decide to
-return error in this case. However, if no clk_set_phase is called or
-maybe the ->set_phase() isn't even implemented, the core->phase would
-never be updated. This is wrong, and we should try to update it when
-all its parent chains are settled down, like the way of updating clock
-rate for that. But it's not deserved to complicate the code now and
-just update it anyway when calling clk_core_get_phase, which would be
-much simple and enough.

-
-commit c420c1e4db22 ("clk: rockchip: Prevent calculating mmc phase
-if clock rate is zero") catches one gremlin again for clk-rk3228.c
-that the parent of SDMMC phase clock should be sclk_sdmmc0, but not
-sclk_sdmmc. However, the naming of the sdmmc clocks varies in the
-manual with the card clock having the 0 while the hclk is named
-without appended 0. So standardize one one format to prevent
-confusion, as there also is only one (non-sdio) mmc controller on
-the soc.

-The MMC sample and drv clock for rockchip platforms are derived from

-
-From: Andrzej Hajda <a.hajda@samsung.com>
-
-[ Upstream commit a8321e7887410a2b2e80ab89d1ef7b30562658ea ]
-
-Rates declared in PLL rate tables should match exactly rates calculated
-from PLL coefficients. If that is not the case, rate of the PLL's child clock
-might be set not as expected. For instance, if in the PLL rates table we have
-a 393216000 Hz entry and the real value as returned by the PLL's recalc_rate
-callback is 393216003, after setting PLL's clk rate to 393216000 clk_get_rate
-will return 393216003. If we now attempt to set rate of a PLL's child divider
-clock to 393216000/2 its rate will be 131072001, rather than 196608000.
-That is, the divider will be set to 3 instead of 2, because 393216003/2 is
-greater than 196608000.
-
-To fix this issue declared rates are changed to exactly match rates generated
-by the PLL, as calculated from the P, M, S, K coefficients.
-
-In this patch an erroneous P value for 74176002 output frequency is also
-corrected.

-
-From: Andrzej Hajda <a.hajda@samsung.com>
-
-[ Upstream commit cdb68fbd4e7962be742c4f29475220c5bf28d8a5 ]
-
-Rates declared in PLL rate tables should match exactly rates calculated from
-the PLL coefficients. If that is not the case, rate of the PLL's child clock
-might be set not as expected. For instance, if in the PLL rates table we have
-a 393216000 Hz entry and the real value as returned by the PLL's recalc_rate
-callback is 393216003, after setting PLL's clk rate to 393216000 clk_get_rate
-will return 393216003. If we now attempt to set rate of a PLL's child divider
-clock to 393216000/2 its rate will be 131072001, rather than 196608000.
-That is, the divider will be set to 3 instead of 2, because 393216003/2 is
-greater than 196608000.
-
-To fix this issue declared rates are changed to exactly match rates generated
-by the PLL, as calculated from the P, M, S, K coefficients.

-
-[ Upstream commit c35b518f9ba06c9de79fb3ff62eed7462d804995 ]
-
-Turns out latest upstream U-Boot does not configure/enable pll_u which
-leaves it at some default rate of 500 kHz:
-
-root@apalis-t30:~# cat /sys/kernel/debug/clk/clk_summary | grep pll_u
- pll_u 3 3 0 500000 0
-
-Of course this won't quite work leading to the following messages:

-From: Felix Fietkau <nbd@nbd.name>
-
-[ Upstream commit 5753405e27f8fe4c42c1537d3ddbd9e058e54cdc ]
-
-__gic_clocksource_init() extracts the GIC_CONFIG_COUNTBITS field from
-read_gic_config() by right shifting the register value. The shift count is
-determined by the most significant bit (__fls) of the bitmask which is
-wrong as it shifts out the complete bitfield.
-
-Use the least significant bit (__ffs) instead to shift the bitfield down to
-bit 0.

-Subject: coresight: Use %px to print pcsr instead of %p
-
-From: Leo Yan <leo.yan@linaro.org>
-
-[ Upstream commit 831c326fcd0e8e2a6ece952f898a1ec9b1dc1004 ]
-
-Commit ad67b74d2469 ("printk: hash addresses printed with %p") lets
-printk specifier %p to hash all addresses before printing, this was
-resulting in the high 32 bits of pcsr can only output zeros. So
-module cannot completely print pc value and it's pointless for debugging
-purpose.
-
-This patch fixes this by using %px to print pcsr instead.

-Subject: cpufreq: CPPC: Initialize shared perf capabilities of CPUs
-
-From: Shunyong Yang <shunyong.yang@hxt-semitech.com>
-
-[ Upstream commit 8913315e9459b146e5888ab5138e10daa061b885 ]
-
-When multiple CPUs are related in one cpufreq policy, the first online
-CPU will be chosen by default to handle cpufreq operations. Let's take
-cpu0 and cpu1 as an example.
-
-When cpu0 is offline, policy->cpu will be shifted to cpu1. cpu1's perf
-capabilities should be initialized. Otherwise, perf capabilities are 0s
-and speed change can not take effect.
-
-This patch copies perf capabilities of the first online CPU to other
-shared CPUs when policy shared type is CPUFREQ_SHARED_TYPE_ANY.

-
-From: Viresh Kumar <viresh.kumar@linaro.org>
-
-[ Upstream commit b24b6478e65f140610ab1ffaadc7bc6bf0be8aad ]
-
-Ideally the de-allocation of resources should happen in the exact
-opposite order in which they were allocated. It helps maintain the code
-in long term, even if nothing really breaks with incorrect ordering.
-
-That wasn't followed in cpufreq_online() and it has some
-inconsistencies. For example, the symlinks were created from within
-the locked region while they are removed only after putting the locks.
-Also ->exit() should have been called only after the symlinks are
-removed and the lock is dropped, as that was the case when ->init()
-was first called.

-When exiting a transformation, the cra_exit() helper is called in each

-is responsible of freeing some areas and of sending one invalidation
-request to the crypto engine, to invalidate the context that was used

-pointer dereferences and other weird issues. All these issues were
-coming from accessing the tfm context.
-
-The issue is the invalidation request completion is checked using a
-wait_for_completion_interruptible() call in both the cipher and hash
-cra_exit() helpers. In some cases this was interrupted while the
-invalidation request wasn't processed yet. And then cra_exit() returned,
-and its caller was freeing the tfm instance. Only then the request was
-being handled by the SafeXcel driver, which lead to the said issues.
-
-This patch fixes this by using wait_for_completion() calls in these
-specific cases.

-Subject: cxl: Check if PSL data-cache is available before issue flush request
-
-From: Vaibhav Jain <vaibhav@linux.vnet.ibm.com>
-
-[ Upstream commit 94322ed8e857e3b2a33cf75118051af9baaa110f ]
-
-PSL9D doesn't have a data-cache that needs to be flushed before
-resetting the card. However when cxl tries to flush data-cache on such
-a card, it times-out as PSL_Control register never indicates flush
-operation complete due to missing data-cache. This is usually
-indicated in the kernel logs with this message:
-
-"WARNING: cache flush timed out"
-
-To fix this the patch checks PSL_Debug register CDC-Field(BIT:27)
-which indicates the absence of a data-cache and sets a flag
-'no_data_cache' in 'struct cxl_native' to indicate this. When
-cxl_data_cache_flush() is called it checks the flag and if set bails
-out early without requesting a data-cache flush operation to the PSL.

-Subject: dmaengine: mv_xor_v2: Fix clock resource by adding a register clock
-
-From: Gregory CLEMENT <gregory.clement@bootlin.com>
-
-[ Upstream commit 3cd2c313f1d618f92d1294addc6c685c17065761 ]
-
-On the CP110 components which are present on the Armada 7K/8K SoC we need
-to explicitly enable the clock for the registers. However it is not
-needed for the AP8xx component, that's why this clock is optional.
-
-With this patch both clock have now a name, but in order to be backward
-compatible, the name of the first clock is not used. It allows to still
-use this clock with a device tree using the old binding.

-Subject: dmaengine: pl330: fix a race condition in case of threaded irqs
-
-From: Qi Hou <qi.hou@windriver.com>
-
-[ Upstream commit a3ca831249ca8c4c226e4ceafee04e280152e59d ]
-
-When booting up with "threadirqs" in command line, all irq handlers of the DMA
-controller pl330 will be threaded forcedly. These threads will race for the same
-list, pl330->req_done.
-
-Before the callback, the spinlock was released. And after it, the spinlock was
-taken. This opened an race window where another threaded irq handler could steal
-the spinlock and be permitted to delete entries of the list, pl330->req_done.
-
-If the later deleted an entry that was still referred to by the former, there would
-be a kernel panic when the former was scheduled and tried to get the next sibling
-of the deleted entry.
-
-The scenario could be depicted as below:
-
- Thread: T1 pl330->req_done Thread: T2
- | | |
- | -A-B-C-D- |
- Locked | |
- | | Waiting
- Del A | |
- | -B-C-D- |
- Unlocked | |
- | | Locked
- Waiting | |
- | | Del B
- | | |
- | -C-D- Unlocked
- Waiting | |
- |
- Locked
- |
- get C via B
- \
- - Kernel panic
-
-The kernel panic looked like as below:
-

-[ Upstream commit 48d163b1aa6e7f650c0b7a4f9c61c387a6def868 ]
-
-When Linux is master of BAM, it can directly read registers to know number
-of supported channels, however when its remotely controlled reading these
-registers would trigger a crash if the BAM is not yet initialized or
-powered up on the remote side.
-
-This patch allows driver to read num-channels and num-ees from Device Tree
-for remotely controlled BAM.

-Subject: dmaengine: rcar-dmac: Check the done lists in rcar_dmac_chan_get_residue()
-
-From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>
-
-[ Upstream commit 3e081628d510b2ddbe493371d9c574d9275da17e ]
-
-This patch fixes an issue that a race condition happens between a client
-driver and the rcar-dmac driver:
-
-- The rcar_dmac_isr_transfer_end() is called.
- - The done list appears, and desc.running is the next active list.
-- rcar_dmac_chan_get_residue() is called by a client driver before
- rcar_dmac_isr_channel_thread() is called.
- - The rcar_dmac_chan_get_residue() will not find any descriptors.
- - And, the following WARNING happens:
- WARN(1, "No descriptor for cookie!");
-
-The sh-sci driver with HSCIF (921,600bps) on R-Car H3 can cause this
-situation.
-So, this patch checks the done lists in rcar_dmac_chan_get_residue()
-and returns zero if the done lists has the argument cookie.

-
-for SRIOV MM IB test it always need more time since MM scheduling
-is not go together with GFX engine, it is controled by h/w MM

-Subject: drm/bridge: sii902x: Retry status read after DDI I2C
-
-From: Linus Walleij <linus.walleij@linaro.org>
-
-[ Upstream commit 2e7a66a8b5ebf1b04a866e5d7c981640f7f62934 ]
-
-The following happens when connection a DVI output driven
-from the SiI9022 using a DVI-to-VGA adapter plug:
-
-i2c i2c-0: sendbytes: NAK bailout.
-i2c i2c-0: sendbytes: NAK bailout.
-
-Then no picture. Apparently the I2C engine inside the SiI9022
-is not smart enough to try to fall back to DDC I2C. Or the
-vendor have not integrated the electronics properly. I don't
-know which one it is.
-
-After this, the I2C bus seems stalled and the first attempt to
-read the status register fails, and the code returns with
-negative return value, and the display fails to initialized.
-
-Instead, retry status readout five times and continue even
-if this fails.
-
-Tested on the ARM Versatile Express with a DVI-to-VGA
-connector, it now gives picture.
-
-Introduce a helper struct device *dev variable to make
-the code more readable.

-Subject: drm/exynos: g2d: use monotonic timestamps
-
-From: Arnd Bergmann <arnd@arndb.de>
-
-[ Upstream commit a588a8bb7b25a3fb4f7fed00feb7aec541fc2632 ]
-
-The exynos DRM driver uses real-time 'struct timeval' values
-for exporting its timestamps to user space. This has multiple
-problems:
-
-1. signed seconds overflow in y2038
-2. the 'struct timeval' definition is deprecated in the kernel
-3. time may jump or go backwards after a 'settimeofday()' syscall
-4. other DRM timestamps are in CLOCK_MONOTONIC domain, so they
- can't be compared
-5. exporting microseconds requires a division by 1000, which may
- be slow on some architectures.
-
-The code existed in two places before, but the IPP portion was
-removed in 8ded59413ccc ("drm/exynos: ipp: Remove Exynos DRM
-IPP subsystem"), so we no longer need to worry about it.
-
-Ideally timestamps should just use 64-bit nanoseconds instead, but
-of course we can't change that now. Instead, this tries to address
-the first four points above by using monotonic 'timespec' values.
-
-According to Tobias Jakobi, user space doesn't care about the
-timestamp at the moment, so we can change the format. Even if
-there is something looking at them, it will work just fine with
-monotonic times as long as the application only looks at the
-relative values between two events.

-From: Lucas Stach <l.stach@pengutronix.de>
-
-[ Upstream commit 6a055b92de15af987b4027826d43aa103c65a3c4 ]
-
-Right now the vblank event completion is racing with the atomic update,
-which is especially bad when the PRE is in use, as one of the hardware
-issue workaround might extend the atomic commit for quite some time.
-
-If the vblank IRQ happens to trigger during that time, we will prematurely
-signal the atomic commit completion to userspace, which causes tearing
-when userspace re-uses a framebuffer we haven't managed to flip away from
-yet.

-Subject: drm/meson: fix vsync buffer update
-
-From: Neil Armstrong <narmstrong@baylibre.com>
-
-[ Upstream commit e88230a3744a71a0b5ecfb45e08ddfe1c884e50d ]
-
-The plane buffer address/stride/height was incorrectly updated in the
-plane_atomic_update operation instead of the vsync irq.
-This patch delays this operation in the vsync irq along with the
-other plane delayed setup.
-
-This issue was masked using legacy framebuffer and X11 modesetting, but
-is clearly visible using gbm rendering when buffer is submitted late after
-vblank, like using software decoding and OpenGL rendering in Kodi.
-With this patch, tearing and other artifacts disappears completely.

-Subject: drm: omapdrm: dss: Move initialization code from component bind to probe
-
-From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
-
-[ Upstream commit 215003b4ae1d47035092fef73b6a22aa82037091 ]
-
-There's no reason to delay initialization of most of the driver (such as
-mapping memory I/O, getting clocks or enabling runtime PM) to the
-component master bind handler.
-
-This additionally fixes a real PM issue caused enabling runtime PM in
-the bind handler.
-
-The bind handler performs the following sequence of PM operations:
-
- pm_runtime_enable(dev);
- pm_runtime_get_sync(dev);
-
- ... (access the hardware to read the device revision) ...
-
- pm_runtime_put_sync(dev);
-
-If a failure occurs at this point, the error path calls
-pm_runtime_disable() to balance the pm_runtime_enable() call.
-
-To understand the problem, it should be noted that the bind handler is
-called when one of the component registers itself, which happens in the
-component's probe handler. Furthermore, as the components are children
-of the DSS, the device core calls pm_runtime_get_sync() on the DSS
-platform device before calling the component's probe handler. This
-increases the DSS power usage count but doesn't runtime resume the
-device, as runtime PM is disabled at that point.
-
-The bind handler is thus called with runtime PM disabled, with the
-device runtime suspended, but with the power usage count larger than 0.
-The pm_runtime_get_sync() call will thus further increase the power
-usage count and runtime resume the device. The pm_runtime_put_sync()
-handler will decrease the power usage count to a non-zero value and will
-thus not suspend the device. Finally, the pm_runtime_disable() call will
-disable runtime PM, preventing the pm_runtime_put() call in the device
-core from runtime suspending the device. The DSS device is thus left
-powered on.
-
-To fix this, move the initialization code from the bind handler to the
-probe handler.

-Subject: drm/rockchip: Respect page offset for PRIME mmap calls
-
-From: "Ørjan Eide" <orjan.eide@arm.com>
-
-[ Upstream commit 57de50af162b67612da99207b061ade3239e57db ]
-
-When mapping external DMA-bufs through the PRIME mmap call, we might be
-given an offset which has to be respected. However for the internal DRM
-GEM mmap path, we have to ignore the fake mmap offset used to identify
-the buffer only. Currently the code always zeroes out vma->vm_pgoff,
-which breaks the former.
-
-This patch fixes the problem by moving the vm_pgoff assignment to a
-function that is used only for GEM mmap path, so that the PRIME path
-retains the original offset.

-Subject: drm/tegra: Shutdown on driver unbind
-
-From: Thierry Reding <treding@nvidia.com>
-
-[ Upstream commit 192b4af6cd28cdad9b42fd79c21a90a2aeb0bec7 ]
-
-Since commit 846c7dfc1193 ("drm/atomic: Try to preserve the crtc enabled
-state in drm_atomic_remove_fb, v2."), removing the last framebuffer will
-no longer disable the corresponding pipeline, which causes the KMS core
-to complain about leaked connectors on driver unbind.
-
-Fix this by calling drm_atomic_helper_shutdown() on driver unbind, which
-will cause all display pipelines to be shut down and therefore drop the
-extra references on the connectors.

-
-From: Thomas Hellstrom <thellstrom@vmware.com>
-
-[ Upstream commit 20fb5a635a0c8478ac98f15cfafc2ea83df29565 ]
-
-We were relying on the pinned screen object backup buffer to be destroyed
-when not used. But if we hold a copy of the atomic state, like when
-hibernating, the backup buffer might not be destroyed since it's
-refcounted by the atomic state. This causes us to hibernate with a
-buffer pinned in VRAM.
-
-Fix this by only having the buffer pinned when it is actually used by a
-screen object.

-
-[ Upstream commit 6b31a2fa1e8f7bc6c2a474b4a12dad7a145cf83d ]
-
-Currently the arm/arm64 runtime code registers the runtime servies
-pagetables with ptdump regardless of whether runtime services page
-tables have been created.
-
-As efi_mm.pgd is NULL in these cases, attempting to dump the efi page
-tables results in a NULL pointer dereference in the ptdump code:

-From: Eric Sandeen <sandeen@redhat.com>
-
-[ Upstream commit 0d9366d67bcf066b028e57d09c9a86ce879bcc28 ]

-If mount is auto-probing for filesystem type, it will try various
-filesystems in order, with the MS_SILENT flag set. We get
-that flag as the silent arg to ext4_fill_super.
-
-If we're probing (silent==1) then don't complain about feature
-incompatibilities that are found if it looks like it's actually
-a different valid extN type - failed probes should be silent
-in this case.
-
-If the on-disk features are unknown even to ext4, then complain.

-Subject: f2fs: fix to set KEEP_SIZE bit in f2fs_zero_range
-
-From: Chao Yu <yuchao0@huawei.com>
-
-[ Upstream commit 17cd07ae95073c298af92c1ba14ac58ce84de33b ]
-
-As Jayashree Mohan reported:
-
-A simple workload to reproduce this would be :
-1. create foo
-2. Write (8K - 16K) // foo size = 16K now
-3. fsync()
-4. falloc zero_range , keep_size (4202496 - 4210688) // foo size must be 16K
-5. fdatasync()
-Crash now
-
-On recovery, we see that the file size is 4210688 and not 16K, which
-violates the semantics of keep_size flag. We have a test case to
-reproduce this using CrashMonkey on 4.15 kernel. Try this out by
-simply running :
- ./c_harness -f /dev/sda -d /dev/cow_ram0 -t f2fs -e 102400 -P -v
- tests/generic_468_zero.so
-
-The root cause is that we miss to set KEEP_SIZE bit correctly in zero_range
-when zeroing block cross EOF with FALLOC_FL_KEEP_SIZE, let's fix this
-missing case.

-Fixing arbitrary kernel leak in case FBIOGETCMAP_SPARC in
-sbusfb_ioctl_helper().

-'index' is defined as an int in sbusfb_ioctl_helper().
-We retrieve this from the user:

-and then we use 'index' in the following way:
-red = cmap->red[index + i] >> 8;
-green = cmap->green[index + i] >> 8;
-blue = cmap->blue[index + i] >> 8;
-
-This is a classic information leak vulnerability. 'index' should be
-an unsigned int, given its usage above.
-
-This patch is straight-forward; it changes 'index' to unsigned int
-in two switch-cases: FBIOGETCMAP_SPARC && FBIOPUTCMAP_SPARC.
-
-This patch fixes CVE-2018-6412.

-[ Upstream commit 90fe6f8ff00a07641ca893d64f75ca22ce77cca2 ]
-
-The test which ensures that the DMI type 1 structure is long enough
-to hold the UUID is off by one. It would fail if the structure is
-exactly 24 bytes long, while that's sufficient to hold the UUID.
-
-I don't expect this bug to cause problem in practice because all
-implementations I have seen had length 8, 25 or 27 bytes, in line
-with the SMBIOS specifications. But let's fix it still.

-Subject: Force log to disk before reading the AGF during a fstrim
-
-From: Carlos Maiolino <cmaiolino@redhat.com>
-
-[ Upstream commit 8c81dd46ef3c416b3b95e3020fb90dbd44e6140b ]
-
-Forcing the log to disk after reading the agf is wrong, we might be
-calling xfs_log_force with XFS_LOG_SYNC with a metadata lock held.
-
-This can cause a deadlock when racing a fstrim with a filesystem
-shutdown.
-
-The deadlock has been identified due a miscalculation bug in device-mapper
-dm-thin, which returns lack of space to its users earlier than the device itself
-really runs out of space, changing the device-mapper volume into an error state.
-
-The problem happened while filling the filesystem with a single file,
-triggering the bug in device-mapper, consequently causing an IO error
-and shutting down the filesystem.
-
-If such file is removed, and fstrim executed before the XFS finishes the
-shut down process, the fstrim process will end up holding the buffer
-lock, and going to sleep on the cil wait queue.
-
-At this point, the shut down process will try to wake up all the threads
-waiting on the cil wait queue, but for this, it will try to hold the
-same buffer log already held my the fstrim, locking up the filesystem.

-Subject: fs: dcache: Avoid livelock between d_alloc_parallel and __d_add
-
-From: Will Deacon <will.deacon@arm.com>
-
-[ Upstream commit 015555fd4d2930bc0c86952c46ad88b3392f66e4 ]
-
-If d_alloc_parallel runs concurrently with __d_add, it is possible for
-d_alloc_parallel to continuously retry whilst i_dir_seq has been
-incremented to an odd value by __d_add:
-
-CPU0:
-__d_add
- n = start_dir_add(dir);
- cmpxchg(&dir->i_dir_seq, n, n + 1) == n
-
-CPU1:
-d_alloc_parallel
-retry:
- seq = smp_load_acquire(&parent->d_inode->i_dir_seq) & ~1;
- hlist_bl_lock(b);
- bit_spin_lock(0, (unsigned long *)b); // Always succeeds
-
-CPU0:
- __d_lookup_done(dentry)
- hlist_bl_lock
- bit_spin_lock(0, (unsigned long *)b); // Never succeeds
-
-CPU1:
- if (unlikely(parent->d_inode->i_dir_seq != seq)) {
- hlist_bl_unlock(b);
- goto retry;
- }
-
-Since the simple bit_spin_lock used to implement hlist_bl_lock does not
-provide any fairness guarantees, then CPU1 can starve CPU0 of the lock
-and prevent it from reaching end_dir_add(dir), therefore CPU1 cannot
-exit its retry loop because the sequence number always has the bottom
-bit set.
-
-This patch resolves the livelock by not taking hlist_bl_lock in
-d_alloc_parallel if the sequence counter is odd, since any subsequent
-masked comparison with i_dir_seq will fail anyway.

-Subject: fscache: Fix hanging wait on page discarded by writeback
-
-From: David Howells <dhowells@redhat.com>
-
-[ Upstream commit 2c98425720233ae3e135add0c7e869b32913502f ]
-
-If the fscache asynchronous write operation elects to discard a page that's
-pending storage to the cache because the page would be over the store limit
-then it needs to wake the page as someone may be waiting on completion of
-the write.
-
-The problem is that the store limit may be updated by a different
-asynchronous operation - and so may miss the write - and that the store
-limit may not even get updated until later by the netfs.
-
-Fix the kernel hang by making fscache_write_op() mark as written any pages
-that are over the limit.

-
-[ Upstream commit 174d1232ebc84fcde8f5889d1171c9c7e74a10a7 ]
-
-The chunk size of allocations in __gfs2_fallocate is calculated
-incorrectly. The size can collapse, causing __gfs2_fallocate to
-allocate one block at a time, which is very inefficient. This needs
-fixing in two places:
-
-In gfs2_quota_lock_check, always set ap->allowed to UINT_MAX to indicate
-that there is no quota limit. This fixes callers that rely on
-ap->allowed to be set even when quotas are off.
-
-In __gfs2_fallocate, reset max_blks to UINT_MAX in each iteration of the
-loop to make sure that allocation limits from one resource group won't
-spill over into another resource group.

-Subject: gianfar: Fix Rx byte accounting for ndev stats
-
-From: Claudiu Manoil <claudiu.manoil@nxp.com>
-
-[ Upstream commit 590399ddf9561f2ed0839311c8ae1be21597ba68 ]
-
-Don't include in the Rx bytecount of the packet sent up the stack:
-the FCB (frame control block), and the padding bytes inserted by
-the controller into the frame payload, nor the FCS. All these are
-being pulled out of the skb by gfar_process_frame().
-This issue is old, likely from the driver's beginnings, however
-it was amplified by recent:
-commit d903ec77118c ("gianfar: simplify FCS handling and fix memory leak")
-which basically added the FCS to the Rx bytecount, and so brought
-this to my attention.

-pwmX_mode is defined in the ABI as 0=DC mode, 1=pwm mode. The chip
-register bit is set to 1 for DC mode. This got mixed up, and writing
-1 into pwmX_mode resulted in DC mode enabled. Fix it up by using

-Subject: i2c: core: report OF style module alias for devices registered via OF
-
-From: Javier Martinez Canillas <javierm@redhat.com>
-
-[ Upstream commit af503716ac1444db61d80cb6d17cfe62929c21df ]
-
-The buses should honor the firmware interface used to register the device,
-but the I2C core reports a MODALIAS of the form i2c:<device> even for I2C
-devices registered via OF.
-
-This means that user-space will never get an OF stype uevent MODALIAS even
-when the drivers modules contain aliases exported from both the I2C and OF
-device ID tables. For example, an Atmel maXTouch Touchscreen registered by
-a DT node with compatible "atmel,maxtouch" has the following module alias:
-
-$ cat /sys/class/i2c-adapter/i2c-8/8-004b/modalias
-i2c:maxtouch
-
-So udev won't be able to auto-load a module for an OF-only device driver.
-Many OF-only drivers duplicate the OF device ID table entries in an I2C ID
-table only has a workaround for how the I2C core reports the module alias.
-
-This patch changes the I2C core to report an OF related MODALIAS uevent if
-the device was registered via OF. So for the previous example, after this
-patch, the reported MODALIAS for the Atmel maXTouch will be the following:
-
-$ cat /sys/class/i2c-adapter/i2c-8/8-004b/modalias
-of:NtrackpadT<NULL>Catmel,maxtouch
-
-NOTE: This patch may break out-of-tree drivers that were relying on this
- behavior, and only had an I2C device ID table even when the device
- was registered via OF. There are no remaining drivers in mainline
- that do this, but out-of-tree drivers have to be fixed and define
- a proper OF device ID table to have module auto-loading working.

-[ Upstream commit 31184d8c6ea49ea0676d100cdd7e1f102ad025b5 ]
-
-The errata FE-8471889 description has been updated. There is still a
-timing violation for repeated start. But the errata now states that it
-was only the case for the Standard mode (100 kHz), in Fast mode (400 kHz)
-there is no issue.
-
-This patch limit the errata fix to the Standard mode.
-
-It has been tesed successfully on the clearfog (Aramda 388 based board).

-
-resolved_dev returned might be NULL as ifindex is transient number.
-Ignoring NULL check of resolved_dev might crash the kernel.
-Therefore perform NULL check before accessing resolved_dev.
-
-Additionally rdma_resolve_ip_route() invokes addr_resolve() which
-performs check and address translation for loopback ifindex.
-Therefore, checking it again in rdma_resolve_ip_route() is not helpful.
-Therefore, the code is simplified to avoid IFF_LOOPBACK check.

-IB spec says that a lid should be ignored when link layer is Ethernet,
-for example when building or parsing a CM request message (CA17-34).
-However, since ib_lid_be16() and ib_lid_cpu16() validates the slid,

-
-From: Jack Morgenstein <jackm@dev.mellanox.co.il>
-
-[ Upstream commit 0077416a3d529baccbe07ab3242e8db541cfadf6 ]
-
-When using IPv4 addresses in RoCEv2, the GID format for the mapped
-IPv4 address should be: ::ffff:<4-byte IPv4 address>.
-
-In the cited commit, IPv4 mapped IPV6 addresses had the 3 upper dwords
-zeroed out by memset, which resulted in deleting the ffff field.
-
-However, since procedure ipv6_addr_v4mapped() already verifies that the
-gid has format ::ffff:<ipv4 address>, no change is needed for the gid,
-and the memset can simply be removed.

-Subject: IB/mlx4: Include GID type when deleting GIDs from HW table under RoCE
-
-From: Jack M <jackm@dev.mellanox.co.il>
-
-[ Upstream commit a18177925c252da7801149abe217c05b80884798 ]
-
-The commit cited below added a gid_type field (RoCEv1 or RoCEv2)
-to GID properties.
-
-When adding GIDs, this gid_type field was copied over to the
-hardware gid table. However, when deleting GIDs, the gid_type field
-was not copied over to the hardware gid table.
-
-As a result, when running RoCEv2, all RoCEv2 gids in the
-hardware gid table were set to type RoCEv1 when any gid was deleted.
-
-This problem would persist until the next gid was added (which would again
-restore the gid_type field for all the gids in the hardware gid table).
-
-Fix this by copying over the gid_type field to the hardware gid table
-when deleting gids, so that the gid_type of all remaining gids is
-preserved when a gid is deleted.

-
-From: Honggang Li <honli@redhat.com>
-
-[ Upstream commit 7672ed33c4c15dbe9d56880683baaba4227cf940 ]
-
-Before commit f1b65df5a232 ("IB/mlx5: Add support for active_width and
-active_speed in RoCE"), the mlx5_ib driver set the default active_width
-and active_speed to IB_WIDTH_4X and IB_SPEED_QDR.
-
-When the RoCE port is down, the RoCE port does not negotiate the active
-width with the remote side, causing the active width to be zero. When
-running userspace ibstat to view the port status, ibstat will panic as it
-reads an invalid width from sys file.
-
-This patch restores the original behavior.

-Subject: IB/uverbs: Fix possible oops with duplicate ioctl attributes
-
-From: Matan Barak <matanb@mellanox.com>
-
-[ Upstream commit 4d39a959bc1f3d164b5a54147fdeb19f84b1ed58 ]
-
-If the same attribute is listed twice by the user in the ioctl attribute
-list then error unwind can cause the kernel to deref garbage.
-
-This happens when an object with WRITE access is sent twice. The second
-parse properly fails but corrupts the state required for the error unwind
-it triggers.
-
-Fixing this by making duplicates in the attribute list invalid. This is
-not something we need to support.
-
-The ioctl interface is currently recommended to be disabled in kConfig.

-[ Upstream commit ecba616e041e64840d14e294b089ca355614b7fb ]
-
-Sorry, the previous change introduced a race condition between
-transmit completion processing and tracking TX descriptors. If a
-completion is received before the number of descriptors is logged,
-the number of descriptors will be add but not removed. After enough
-times, this could halt the transmit queue forever.
-
-Log the number of descriptors used by a transmit before sending.
-I stress tested the fix on two different systems running over the
-weekend without any issues.

-Subject: ibmvnic: Zero used TX descriptor counter on reset
-
-From: Thomas Falcon <tlfalcon@linux.vnet.ibm.com>
-
-[ Upstream commit 41f714672f93608751dbd2fa2291d476a8ff0150 ]
-
-The counter that tracks used TX descriptors pending completion
-needs to be zeroed as part of a device reset. This change fixes
-a bug causing transmit queues to be stopped unnecessarily and in
-some cases a transmit queue stall and timeout reset. If the counter
-is not reset, the remaining descriptors will not be "removed",
-effectively reducing queue capacity. If the queue is over half full,
-it will cause the queue to stall if stopped.

-
-From: Harry Morris <h.morris@cascoda.com>
-
-[ Upstream commit 86674a97f5055f4c7f406563408096e8cf9364ff ]
-
-In ca8210_test_int_user_write() a user can request the transfer of a
-frame with a length field (command.length) that is longer than the
-actual buffer provided (len). In this scenario the driver will copy
-the buffer contents into the uninitialised command[] buffer, then
-transfer <data.length> bytes over the SPI even though only <len> bytes
-had been populated, potentially leaking sensitive kernel memory.
-
-Also the first 6 bytes of the command buffer must be initialised in case
-a malformed, short packet is written and the uninitialised bytes are
-read in ca8210_test_check_upstream.

-Subject: ima: Fallback to the builtin hash algorithm
-
-From: Petr Vorel <pvorel@suse.cz>
-
-[ Upstream commit ab60368ab6a452466885ef4edf0cefd089465132 ]
-
-IMA requires having it's hash algorithm be compiled-in due to it's
-early use. The default IMA algorithm is protected by Kconfig to be
-compiled-in.
-
-The ima_hash kernel parameter allows to choose the hash algorithm. When
-the specified algorithm is not available or available as a module, IMA
-initialization fails, which leads to a kernel panic (mknodat syscall calls
-ima_post_path_mknod()). Therefore as fallback we force IMA to use
-the default builtin Kconfig hash algorithm.
-
-Fixed crash:

-
-[ Upstream commit 9ad577087165478c9d9be82b15ed9bf2db5835f5 ]
-
-Since commit 8edc514b01e9 ("intel_th: Make SOURCE devices children of the
-root device") the hub is not the parent of SOURCE devices any more, so the
-new helper function should be used for that instead of always using the
-parent. The intel_th_set_output() path, however, still uses the old
-logic, leading to the hub driver structure being aliased with something
-else, like struct pci_driver or struct acpi_driver, and an incorrect call
-to an address inferred from that, potentially resulting in a crash.

-Subject: iommu/amd: Take into account that alloc_dev_data() may return NULL
-
-From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
-
-[ Upstream commit 39ffe39545cd5cb5b8cee9f0469165cf24dc62c2 ]
-
-find_dev_data() does not check whether the return value alloc_dev_data()
-is NULL. This was okay once because the pointer was returned once as-is.
-Since commit df3f7a6e8e85 ("iommu/amd: Use is_attach_deferred
-call-back") the pointer may be used within find_dev_data() so a NULL
-check is required.

-Subject: iommu/mediatek: Fix protect memory setting
-
-From: Yong Wu <yong.wu@mediatek.com>
-
-[ Upstream commit 70ca608b2ec6dafa6bb1c2b0691852fc78f8f717 ]
-
-In MediaTek's IOMMU design, When a iommu translation fault occurs
-(HW can NOT translate the destination address to a valid physical
-address), the IOMMU HW output the dirty data into a special memory
-to avoid corrupting the main memory, this is called "protect memory".
-the register(0x114) for protect memory is a little different between
-mt8173 and mt2712.
-
-In the mt8173, bit[30:6] in the register represents [31:7] of the
-physical address. In the 4GB mode, the register bit[31] should be 1.
-While in the mt2712, the bits don't shift. bit[31:7] in the register
-represents [31:7] in the physical address, and bit[1:0] in the
-register represents bit[33:32] of the physical address if it has.

-[ Upstream commit ffc2b6ee417435605ee8bb1eb4c8f02e9ff4b4a5 ]
-
-It's safe to remove the setting of dev's needed_headroom and mtu in
-__gre_tunnel_init, as discussed in [1], ip_tunnel_newlink can do it
-properly.
-
-Now Eric noticed that it could cover the mtu value set in do_setlink
-when creating a ip_gre dev. It makes IFLA_MTU param not take effect.
-
-So this patch is to remove them to make IFLA_MTU work, as in other
-ipv4 tunnels.

-Subject: ipv4: lock mtu in fnhe when received PMTU < net.ipv4.route.min_pmtu
-
-From: Sabrina Dubroca <sd@queasysnail.net>
-
-[ Upstream commit d52e5a7e7ca49457dd31fc8b42fb7c0d58a31221 ]
-
-Prior to the rework of PMTU information storage in commit
-2c8cec5c10bc ("ipv4: Cache learned PMTU information in inetpeer."),
-when a PMTU event advertising a PMTU smaller than
-net.ipv4.route.min_pmtu was received, we would disable setting the DF
-flag on packets by locking the MTU metric, and set the PMTU to
-net.ipv4.route.min_pmtu.
-
-Since then, we don't disable DF, and set PMTU to
-net.ipv4.route.min_pmtu, so the intermediate router that has this link
-with a small MTU will have to drop the packets.
-
-This patch reestablishes pre-2.6.39 behavior by splitting
-rtable->rt_pmtu into a bitfield with rt_mtu_locked and rt_pmtu.
-rt_mtu_locked indicates that we shouldn't set the DF bit on that path,
-and is checked in ip_dont_fragment().
-
-One possible workaround is to set net.ipv4.route.min_pmtu to a value low
-enough to accommodate the lowest MTU encountered.

-Subject: ipvs: remove IPS_NAT_MASK check to fix passive FTP
-
-From: Julian Anastasov <ja@ssi.bg>
-
-[ Upstream commit 8a949fff0302b50063f74bb345a66190015528d0 ]
-
-The IPS_NAT_MASK check in 4.12 replaced previous check for nfct_nat()
-which was needed to fix a crash in 2.6.36-rc, see
-commit 7bcbf81a2296 ("ipvs: avoid oops for passive FTP").
-But as IPVS does not set the IPS_SRC_NAT and IPS_DST_NAT bits,
-checking for IPS_NAT_MASK prevents PASV response to be properly
-mangled and blocks the transfer. Remove the check as it is not
-needed after 3.12 commit 41d73ec053d2 ("netfilter: nf_conntrack:
-make sequence number adjustments usuable without NAT") which
-changes nfct_nat() with nfct_seqadj() and especially after 3.13
-commit b25adce16064 ("ipvs: correct usage/allocation of seqadj
-ext in ipvs").
-
-Thanks to Li Shuang and Florian Westphal for reporting the problem!

-Subject: iwlwifi: avoid collecting firmware dump if not loaded
-
-From: Shaul Triebitz <shaul.triebitz@intel.com>
-
-[ Upstream commit 8745f12a6600dd9d31122588621d4c8ddb332cd7 ]
-
-Trying to collect firmware debug data while firmware
-is not loaded causes various errors (e.g. failing NIC access).
-This causes even a bigger issue if at that time the
-HW radio is off.
-In that case, when later turning the radio on, the Driver
-fails to read the HW (registers contain garbage values).
-(It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN
-bit is cleared on faulty NIC access - since the same behavior
-was seen in HW RFKILL toggling before setting that bit.)

-Subject: iwlwifi: mvm: check if mac80211_queue is valid in iwl_mvm_disable_txq
-
-From: Luca Coelho <luciano.coelho@intel.com>
-
-[ Upstream commit 9a233bb8025105db9a60b5d761005cc5a6c77f3d ]
-
-Sometimes iwl_mvm_disable_txq() may be called with mac80211_queue ==
-IEEE80211_INVAL_HW_QUEUE, and this would cause us to use BIT(0xFF)
-which is way too large for the u16 we used to store it in
-hw_queue_to_mac820211. If this happens the following UBSAN warning
-will be generated:
-
-[ 167.185167] UBSAN: Undefined behaviour in drivers/net/wireless/intel/iwlwifi/mvm/utils.c:838:5
-[ 167.185171] shift exponent 255 is too large for 64-bit type 'long unsigned int'
-
-Fix that by checking that it is not IEEE80211_INVAL_HW_QUEUE and,
-while at it, add a warning if the queue number is larger than
-IEEE80211_MAX_QUEUES.

-Subject: iwlwifi: mvm: clear tx queue id when unreserving aggregation queue
-
-From: Avraham Stern <avraham.stern@intel.com>
-
-[ Upstream commit 4b387906b1c3692bb790388c335515c0cf098a23 ]
-
-When a queue is reserved for aggregation, the queue id is assigned
-to the tid_data. This is fine since iwl_mvm_sta_tx_agg_oper()
-takes care of allocating the queue before actual tx starts.
-When the reservation is cancelled (e.g. when the AP declined the
-aggregation request) the tid_data is not cleared. As a result,
-following tx for this tid was trying to use an unallocated queue.

-Currently when an IGTK is set for an AP, it is set as a regular key.
-Since the cipher is set to CMAC, the STA_KEY_FLG_EXT flag is added to
-the host command, which causes assert 0x253D on NICs that do not support

-From: Ilan Peer <ilan.peer@intel.com>
-
-[ Upstream commit 6508de0305d560235b366cc2cc98f7bcfb029e92 ]
-
-In the scheduler config command, the meaning of tid == 0xf was intended
-to indicate the configuration is for management frames. However,
-tid == 0xf was also used for the multicast queue that was meant only
-for multicast data frames, which resulted with the FW not encrypting
-multicast data frames.
-
-As multicast frames do not have a QoS header, fix this by setting
-tid == 0, to indicate that this is a data queue and not management
-one.

-We should add the multicast station before adding the

-
-However, in older FW, the firmware will start beaconing
-when we add the multicast station, and since the broadcast

-Subject: iwlwifi: mvm: fix "failed to remove key" message
-
-From: Sara Sharon <sara.sharon@intel.com>
-
-[ Upstream commit e4f13ad07823b24a1537518d2163bd164292fb10 ]
-
-When the GTK is installed, we install it to HW with the
-station ID of the AP.
-
-Mac80211 will try to remove it only after the AP sta is
-removed, which will result in a failure to remove key
-since we do not have any station for it.
-
-This is a valid situation, but a previous commit removed
-the early return and added a return with error value, which
-resulted in an error message that is confusing to users.
-
-Remove the error return value.

-Subject: iwlwifi: mvm: fix IBSS for devices that support station type API
-
-From: Sara Sharon <sara.sharon@intel.com>
-
-[ Upstream commit fc07bd8ce19bff9e7479c04077ddb5957d1a27be ]
-
-In IBSS, the mac80211 sets the cab_queue to be invalid.
-
-However, the multicast station uses it, so we need to override it.
-
-A previous patch did it, but it was nested inside the if's and was
-applied only for legacy FWs that don't support the new station type
-API, instead of being applied for all paths.
-
-In addition, add a missing NL80211_IFTYPE_ADHOC to the initialization
-of the queues in iwl_mvm_mac_ctxt_init()

-
-From: Sara Sharon <sara.sharon@intel.com>
-
-[ Upstream commit 5ab2ba931255d8bf03009c06d58dce97de32797c ]
-
-A previous patch allowed the same PN for packets originating from the
-same AMSDU by copying PN only for the last packet in the series.
-
-This however is bogus since we cannot assume the last frame will be
-received on the same queue, and if it is received on a different ueue
-we will end up not incrementing the PN and possibly let the next
-packet to have the same PN and pass through.
-
-Change the logic instead to driver explicitly indicate for the second
-sub frame and on to be allowed to have the same PN as the first
-subframe. Indicate it to mac80211 as well for the fallback queue.

-Subject: iwlwifi: mvm: Increase session protection time after CS
-
-From: Andrei Otcheretianski <andrei.otcheretianski@intel.com>
-
-[ Upstream commit 19125cb0591ae63cd4591e3dfe4c22058e748518 ]
-
-After switching to a new channel, driver schedules session protection
-time event in order to hear the beacon on the new channel.
-The duration of the protection is two beacon intervals.
-However, since we start to switch slightly before beacon with count 1, in
-case we don't hear (or AP doesn't transmit) the very first beacon on the
-new channel the protection ends without hearing any beacon at all.
-At this stage the switch is not complete, the queues are closed and the
-interface doesn't have quota yet or TBTT events. As the result, we are
-stuck forever waiting for iwl_mvm_post_channel_switch() to be called.
-
-Fix this by increasing the protection time to be 3 beacon intervals and
-in addition drop the connection if the time event ends before we got any
-beacon.

-Subject: iwlwifi: mvm: set the correct tid when we flush the MCAST sta
-
-From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
-
-[ Upstream commit 334167decf98f01a66c91ea84180c278bc4ad290 ]
-
-The tid being used for the queue (cab_queue) for the MCAST
-station has been changed recently to be 0 (for BE).
-The flush path still flushed only the special tid (15)
-which means that the firmware wasn't flushing the right
-queue and we could get a firmware crash upon remove
-station if we had an MCAST packet on the ring.
-
-The current code that flushes queues for a station only
-differentiates between internal stations (stations that
-aren't instantiated in mac80211, like the MCAST station)
-and the non-internal ones.
-Internal stations can be either: BCAST (beacons), MCAST
-(for cab_queue), GENERAL_PURPOSE (p2p dev, and sniffer
-injection). The internal stations can use different tids.
-
-To make the code simpler, just flush all the tids always
-and add the special internal tid (15) for internal
-stations. The firmware will know how to handle this even
-if we hadn't any queue mapped that that tid.

-Subject: ixgbe: prevent ptp_rx_hang from running when in FILTER_ALL mode
-
-From: Jacob Keller <jacob.e.keller@intel.com>
-
-[ Upstream commit 6704a3abf4cf4181a1ee64f5db4969347b88ca1d ]
-
-On hardware which supports timestamping all packets, the timestamps are
-recorded in the packet buffer, and the driver no longer uses or reads
-the registers. This makes the logic for checking and clearing Rx
-timestamp hangs meaningless.
-
-If we run the ixgbe_ptp_rx_hang() function in this case, then the driver
-will continuously spam the log output with "Clearing Rx timestamp hang".
-These messages are spurious, and confusing to end users.
-
-The original code in commit a9763f3cb54c ("ixgbe: Update PTP to support
-X550EM_x devices", 2015-12-03) did have a flag PTP_RX_TIMESTAMP_IN_REGISTER
-which was intended to be used to avoid the Rx timestamp hang check,
-however it did not actually check the flag before calling the function.
-
-Do so now in order to stop the checks and prevent the spurious log
-messages.

-
-From: Nicolas Pitre <nicolas.pitre@linaro.org>
-
-[ Upstream commit 825d487583089f9a33d31650c9c41f6474aab7fc ]
-
-Some filesystems have timestamps with coarse precision that may allow
-for a recently built object file to have the same timestamp as the
-updated time on one of its dependency files. When that happens, the
-object file doesn't get rebuilt as it should.
-
-This is especially the case on filesystems that don't have sub-second
-time precision, such as ext3 or Ext4 with 128B inodes.
-
-Let's prevent that by making sure updated dependency files have a newer
-timestamp than the first file we created (i.e. autoksyms.h.tmpnew).

-From: Vitaly Kuznetsov <vkuznets@redhat.com>
-
-[ Upstream commit 0bcc3fb95b97ac2ca223a5a870287b37f56265ac ]
-
-Devices which use level-triggered interrupts under Windows 2016 with
-Hyper-V role enabled don't work: Windows disables EOI broadcast in SPIV
-unconditionally. Our in-kernel IOAPIC implementation emulates an old IOAPIC
-version which has no EOI register so EOI never happens.
-
-The issue was discovered and discussed a while ago:
-https://www.spinics.net/lists/kvm/msg148098.html
-
-While this is a guest OS bug (it should check that IOAPIC has the required
-capabilities before disabling EOI broadcast) we can workaround it in KVM:
-advertising DIRECTED_EOI with in-kernel IOAPIC makes little sense anyway.

-From: Laurent Vivier <lvivier@redhat.com>

-
-Since commit 8b24e69fc47e ("KVM: PPC: Book3S HV: Close race with testing
-for signals on guest entry"), if CONFIG_VIRT_CPU_ACCOUNTING_GEN is set, the
-guest time is not accounted to guest time and user time, but instead to
-system time.
-
-This is because guest_enter()/guest_exit() are called while interrupts
-are disabled and the tick counter cannot be updated between them.
-
-To fix that, move guest_exit() after local_irq_enable(), and as
-guest_enter() is called with IRQ disabled, call guest_enter_irqoff()
-instead.

-Subject: KVM: PPC: Book3S HV: Fix VRMA initialization with 2MB or 1GB memory backing
-
-From: Paul Mackerras <paulus@ozlabs.org>
-
-[ Upstream commit debd574f4195e205ba505b25e19b2b797f4bcd94 ]
-
-The current code for initializing the VRMA (virtual real memory area)
-for HPT guests requires the page size of the backing memory to be one
-of 4kB, 64kB or 16MB. With a radix host we have the possibility that
-the backing memory page size can be 2MB or 1GB. In these cases, if the
-guest switches to HPT mode, KVM will not initialize the VRMA and the
-guest will fail to run.
-
-In fact it is not necessary that the VRMA page size is the same as the
-backing memory page size; any VRMA page size less than or equal to the
-backing memory page size is acceptable. Therefore we now choose the
-largest page size out of the set {4k, 64k, 16M} which is not larger
-than the backing memory page size.

-Subject: KVM: VMX: raise internal error for exception during invalid protected mode state
-
-From: Sean Christopherson <sean.j.christopherson@intel.com>
-
-[ Upstream commit add5ff7a216ee545a214013f26d1ef2f44a9c9f8 ]
-
-Exit to userspace with KVM_INTERNAL_ERROR_EMULATION if we encounter
-an exception in Protected Mode while emulating guest due to invalid
-guest state. Unlike Big RM, KVM doesn't support emulating exceptions
-in PM, i.e. PM exceptions are always injected via the VMCS. Because
-we will never do VMRESUME due to emulation_required, the exception is
-never realized and we'll keep emulating the faulting instruction over
-and over until we receive a signal.
-
-Exit to userspace iff there is a pending exception, i.e. don't exit
-simply on a requested event. The purpose of this check and exit is to
-aid in debugging a guest that is in all likelihood already doomed.
-Invalid guest state in PM is extremely limited in normal operation,
-e.g. it generally only occurs for a few instructions early in BIOS,
-and any exception at this time is all but guaranteed to be fatal.
-Non-vectored interrupts, e.g. INIT, SIPI and SMI, can be cleanly
-handled/emulated, while checking for vectored interrupts, e.g. INTR
-and NMI, without hitting false positives would add a fair amount of
-complexity for almost no benefit (getting hit by lightning seems
-more likely than encountering this specific scenario).
-
-Add a WARN_ON_ONCE to vmx_queue_exception() if we try to inject an
-exception via the VMCS and emulation_required is true.

-
-The culprit is quite simple: The driver tries to access the phy left and right,
-but only actually has a working reference to it when the device is up.
-
-The fix thus is quite simple too: Get a reference to the phy on probe already
-and keep it even when the device is going down.
-
-With this patch applied, I can successfully run wicked on my system and bring
-the interface up and down as many times as I want, without getting NULL pointer
-dereferences in between.

-[ Upstream commit e69647a19c870c2f919e4d5023af8a515e8ef25f ]
-
-Description:
-EEE does not work with lan7800 when AutoSpeed is not set.
-(This can happen when EEPROM is not populated or configured incorrectly)
-
-Root-Cause:
-When EEE is enabled, the mac config register ASD is not set
-i.e. in default state, causing EEE fail.
-
-Fix:
-Set the register when eeprom is not present.

-
-As reported by Dan the parentheses is in the wrong place, and since
-unlikely() call returns either 0 or 1 it's never less than zero. The
-second issue is that signed integer overflows like "INT_MAX + 1" are
-undefined behavior.
-
-Since num_test_devs represents the number of devices, we want to stop
-prior to hitting the max, and not rely on the wrap arround at all. So
-just cap at num_test_devs + 1, prior to assigning a new device.

-Subject: llc: properly handle dev_queue_xmit() return value
-
-From: Cong Wang <xiyou.wangcong@gmail.com>
-
-[ Upstream commit b85ab56c3f81c5a24b5a5213374f549df06430da ]
-
-llc_conn_send_pdu() pushes the skb into write queue and
-calls llc_conn_send_pdus() to flush them out. However, the
-status of dev_queue_xmit() is not returned to caller,
-in this case, llc_conn_state_process().
-
-llc_conn_state_process() needs hold the skb no matter
-success or failure, because it still uses it after that,
-therefore we should hold skb before dev_queue_xmit() when
-that skb is the one being processed by llc_conn_state_process().
-
-For other callers, they can just pass NULL and ignore
-the return value as they are.

-Subject: locking/xchg/alpha: Add unconditional memory barrier to cmpxchg()
-
-From: Andrea Parri <parri.andrea@gmail.com>
-
-[ Upstream commit cb13b424e986aed68d74cbaec3449ea23c50e167 ]
-
-Continuing along with the fight against smp_read_barrier_depends() [1]
-(or rather, against its improper use), add an unconditional barrier to
-cmpxchg. This guarantees that dependency ordering is preserved when a
-dependency is headed by an unsuccessful cmpxchg. As it turns out, the
-change could enable further simplification of LKMM as proposed in [2].

-
-From: Andrea Parri <parri.andrea@gmail.com>
-
-[ Upstream commit 472e8c55cf6622d1c112dc2bc777f68bbd4189db ]
-
-Successful RMW operations are supposed to be fully ordered, but
-Alpha's xchg() and cmpxchg() do not meet this requirement.
-
-Will Deacon noticed the bug:
-
- > So MP using xchg:
- >
- > WRITE_ONCE(x, 1)
- > xchg(y, 1)
- >
- > smp_load_acquire(y) == 1
- > READ_ONCE(x) == 0
- >
- > would be allowed.
-
-... which thus violates the above requirement.
-
-Fix it by adding a leading smp_mb() to the xchg() and cmpxchg() implementations.

-Subject: loop: don't call into filesystem while holding lo_ctl_mutex
-
-From: Omar Sandoval <osandov@fb.com>
-
-[ Upstream commit 2d1d4c1e591fd40bd7dafd868a249d7d00e215d5 ]
-
-We hit an issue where a loop device on NFS was stuck in
-loop_get_status() doing vfs_getattr() after the NFS server died, which
-caused a pile-up of uninterruptible processes waiting on lo_ctl_mutex.
-There's no reason to hold this lock while we wait on the filesystem;
-let's drop it so that other processes can do their thing. We need to
-grab a reference on lo_backing_file while we use it, and we can get rid
-of the check on lo_device, which has been unnecessary since commit
-a34c0ae9ebd6 ("[PATCH] loop: remove the bio remapping capability") in
-the linux-history tree.

-It is not fatal, the driver and the system continue to function normally.

-As per the warning the coherent_dma_mask is not set on this device.
-There is nothing special about the DMA memory coherency on this hardware

-Subject: mac80211: Do not disconnect on invalid operating class
-
-From: Ilan Peer <ilan.peer@intel.com>
-
-[ Upstream commit 191da271ac260700db3e5b4bb982a17ca78769d6 ]
-
-Some APs include a non global operating class in their extended channel
-switch information element. In such a case, as the operating class is not
-known, mac80211 would decide to disconnect.
-
-However the specification states that the operating class needs to be
-taken from Annex E, but it does not specify from which table it should be
-taken, so it is valid for an AP to use a non global operating class.
-
-To avoid possibly unneeded disconnection, in such a case ignore the
-operating class and assume that the current band is used, and if the
-resulting channel and band configuration is invalid disconnect.

-Commit d02fd6e7d293 ("macvlan: Fix one possible double free") handles
-the case when register_netdevice() invokes ndo_uninit() on error and
-as a result free the port. But 'macvlan_port_get_rtnl(dev))' check
-(returns dev->rx_handler_data), which was added by this commit in order
-to prevent double free, is not quite correct:
-
-* for macvlan it always returns NULL because 'lowerdev' is the one that
- was used to register rx handler (port) in macvlan_port_create() as
- well as to unregister it in macvlan_port_destroy().
-* for macvtap it always returns a valid pointer because macvtap registers
- its own rx handler before macvlan_common_newlink().

-Subject: md: fix a potential deadlock of raid5/raid10 reshape
-
-From: BingJing Chang <bingjingc@synology.com>
-
-[ Upstream commit 8876391e440ba615b10eef729576e111f0315f87 ]
-
-There is a potential deadlock if mount/umount happens when
-raid5_finish_reshape() tries to grow the size of emulated disk.
-
-How the deadlock happens?
-1) The raid5 resync thread finished reshape (expanding array).
-2) The mount or umount thread holds VFS sb->s_umount lock and tries to
- write through critical data into raid5 emulated block device. So it
- waits for raid5 kernel thread handling stripes in order to finish it
- I/Os.
-3) In the routine of raid5 kernel thread, md_check_recovery() will be
- called first in order to reap the raid5 resync thread. That is,
- raid5_finish_reshape() will be called. In this function, it will try
- to update conf and call VFS revalidate_disk() to grow the raid5
- emulated block device. It will try to acquire VFS sb->s_umount lock.
-The raid5 kernel thread cannot continue, so no one can handle mount/
-umount I/Os (stripes). Once the write-through I/Os cannot be finished,
-mount/umount will not release sb->s_umount lock. The deadlock happens.
-
-The raid5 kernel thread is an emulated block device. It is responible to
-handle I/Os (stripes) from upper layers. The emulated block device
-should not request any I/Os on itself. That is, it should not call VFS
-layer functions. (If it did, it will try to acquire VFS locks to
-guarantee the I/Os sequence.) So we have the resync thread to send
-resync I/O requests and to wait for the results.
-
-For solving this potential deadlock, we can put the size growth of the
-emulated block device as the final step of reshape thread.
-
-2017/12/29:
-Thanks to Guoqing Jiang <gqjiang@suse.com>,
-we confirmed that there is the same deadlock issue in raid10. It's
-reproducible and can be fixed by this patch. For raid10.c, we can remove
-the similar code to prevent deadlock as well since they has been called
-before.

-Subject: md: fix md_write_start() deadlock w/o metadata devices
-
-From: Heinz Mauelshagen <heinzm@redhat.com>
-
-[ Upstream commit 4b6c1060eaa6495aa5b0032e8f2d51dd936b1257 ]
-
-If no metadata devices are configured on raid1/4/5/6/10
-(e.g. via dm-raid), md_write_start() unconditionally waits
-for superblocks to be written thus deadlocking.
-
-Fix introduces mddev->has_superblocks bool, defines it in md_run()
-and checks for it in md_write_start() to conditionally avoid waiting.
-
-Once on it, check for non-existing superblocks in md_super_write().

-Subject: md/raid1: fix NULL pointer dereference
-
-From: Yufen Yu <yuyufen@huawei.com>
-
-[ Upstream commit 3de59bb9d551428cbdc76a9ea57883f82e350b4d ]
-
-In handle_write_finished(), if r1_bio->bios[m] != NULL, it thinks
-the corresponding conf->mirrors[m].rdev is also not NULL. But, it
-is not always true.
-
-Even if some io hold replacement rdev(i.e. rdev->nr_pending.count > 0),
-raid1_remove_disk() can also set the rdev as NULL. That means,
-bios[m] != NULL, but mirrors[m].rdev is NULL, resulting in NULL
-pointer dereference in handle_write_finished and sync_request_write.
-

-Subject: md raid10: fix NULL deference in handle_write_completed()
-
-From: Yufen Yu <yuyufen@huawei.com>
-
-[ Upstream commit 01a69cab01c184d3786af09e9339311123d63d22 ]
-
-In the case of 'recover', an r10bio with R10BIO_WriteError &
-R10BIO_IsRecover will be progressed by handle_write_completed().
-This function traverses all r10bio->devs[copies].
-If devs[m].repl_bio != NULL, it thinks conf->mirrors[dev].replacement
-is also not NULL. However, this is not always true.
-
-When there is an rdev of raid10 has replacement, then each r10bio
-->devs[m].repl_bio != NULL in conf->r10buf_pool. However, in 'recover',
-even if corresponded replacement is NULL, it doesn't clear r10bio
-->devs[m].repl_bio, resulting in replacement NULL deference.
-
-This bug was introduced when replacement support for raid10 was
-added in Linux 3.3.
-
-As NeilBrown suggested:
- Elsewhere the determination of "is this device part of the
- resync/recovery" is made by resting bio->bi_end_io.
- If this is end_sync_write, then we tried to write here.
- If it is NULL, then we didn't try to write.
-
-Fixes: 9ad1aefc8ae8 ("md/raid10: Handle replacement devices during resync.")

-Subject: md: raid5: avoid string overflow warning
-
-From: Arnd Bergmann <arnd@arndb.de>
-
-[ Upstream commit 53b8d89ddbdbb0e4625a46d2cdbb6f106c52f801 ]
-
-gcc warns about a possible overflow of the kmem_cache string, when adding
-four characters to a string of the same length:
-
-drivers/md/raid5.c: In function 'setup_conf':
-drivers/md/raid5.c:2207:34: error: '-alt' directive writing 4 bytes into a region of size between 1 and 32 [-Werror=format-overflow=]
- sprintf(conf->cache_name[1], "%s-alt", conf->cache_name[0]);
- ^~~~
-drivers/md/raid5.c:2207:2: note: 'sprintf' output between 5 and 36 bytes into a destination of size 32
- sprintf(conf->cache_name[1], "%s-alt", conf->cache_name[0]);
- ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-If I'm counting correctly, we need 11 characters for the fixed part
-of the string and 18 characters for a 64-bit pointer (when no gendisk
-is used), so that leaves three characters for conf->level, which should
-always be sufficient.
-
-This makes the code use snprintf() with the correct length, to
-make the code more robust against changes, and to get the compiler
-to shut up.
-
-In commit f4be6b43f1ac ("md/raid5: ensure we create a unique name for
-kmem_cache when mddev has no gendisk") from 2010, Neil said that
-the pointer could be removed "shortly" once devices without gendisk
-are disallowed. I have no idea if that happened, but if it did, that
-should probably be changed as well.

-
-[ Upstream commit 779c79d4b833ec646b0aed878da38edb45bbe156 ]

-Hauppauge produced a revision of ImpactVCBe using an 888,
-with a 25MHz crystal, instead of using the default third
-overtone 50Mhz crystal. This overrides that frequency so
-that the cx25840 is properly configured. Without the proper

-From: Colin Ian King <colin.king@canonical.com>
-
-[ Upstream commit 67300abdbe9f1717532aaf4e037222762716d0f6 ]
-
-Currently an out of range dev->nr is detected by just reporting the
-issue and later on an out-of-bounds read on array card occurs because
-of this. Fix this by checking the upper range of dev->nr with the size
-of array card (removes the hard coded size), move this check earlier
-and also exit with the error -ENOSYS to avoid the later out-of-bounds
-array read.
-
-Detected by CoverityScan, CID#711191 ("Out-of-bounds-read")

-
-Hauppauge em28xx bulk devices exhibit continuity errors and corrupted
-packets, when run in VMWare virtual machines. Unknown if other
-manufacturers bulk models exhibit the same issue. KVM/Qemu is unaffected.
-
-According to documentation the maximum packet multiplier for em28xx in bulk
-transfer mode is 256 * 188 bytes. This changes the size of bulk transfers
-to maximum supported value and have a bonus beneficial alignment.
-
-Before:
-
-After:
-
-This sets up USB to expect just as many bytes as the em28xx is set to emit.
-
-Successful usage under load afterwards natively and in both VMWare
-and KVM/Qemu virtual machines.

-
-From: Kieran Bingham <kieran.bingham@ideasonboard.com>
-
-[ Upstream commit 9f564184e6cc21a86c26bab920afac1bab7653ff ]
-
-The ADV748x handles interlaced media using V4L2_FIELD_ALTERNATE field
-types. The correct specification for the height on the mbus is the
-image height, in this instance, the field height.
-
-The AFE component already correctly adjusts the height on the mbus, but
-the HDMI component got left behind.
-
-Adjust the mbus height to correctly describe the image height of the
-fields when processing interlaced video for HDMI pipelines.

-
-From: Arnd Bergmann <arnd@arndb.de>
-
-[ Upstream commit a398e043637a4819a0e96467bfecaabf3224dd62 ]
-
-While experimenting with older compiler versions, I ran
-into a warning that no longer shows up on gcc-4.8 or newer:
-
-drivers/media/platform/s3c-camif/camif-capture.c: In function '__camif_subdev_try_format':
-drivers/media/platform/s3c-camif/camif-capture.c:1265:25: error: array subscript is below array bounds
-
-This is an off-by-one bug, leading to an access before the start of the
-array, while newer compilers silently assume this undefined behavior
-cannot happen and leave the loop at index 0 if no other entry matches.
-
-As Sylvester explains, we actually need to ensure that the
-value is within the range, so this reworks the loop to be
-easier to parse correctly, and an additional check to fall
-back on the first format value for any unexpected input.
-
-I found an existing gcc bug for it and added a reduced version
-of the function there.

-Subject: media: vb2: Fix videobuf2 to map correct area
-
-From: Masami Hiramatsu <mhiramat@kernel.org>
-
-[ Upstream commit d13a0139d7874a0577b5955d6eed895517d23b72 ]
-
-Fixes vb2_vmalloc_get_userptr() to ioremap correct area.
-Since the current code does ioremap the page address, if the offset > 0,
-it does not do ioremap the last page and results in kernel panic.
-
-This fixes to pass the size + offset to ioremap so that ioremap
-can map correct area. Also, this uses __pfn_to_phys() to get the physical
-address of given PFN.

-The vivid driver has two custom controls that change the behavior of RDS.

-According to the QCA u-boot source the "PCIE Phase Lock Loop
-Configuration (PCIE_PLL_CONFIG)" register is for all SoCs except the
-QCA955X and QCA956X at offset 0x10.
-
-Since the PCIE PLL config register is only defined for the AR724x fix
-only this value. The value is wrong since the day it was added and isn't

-We now have a platform (Ranchu) in the "generic" platform which matches
-based on the FDT compatible string using mips_machine_is_compatible(),
-however that function doesn't stop at a blank struct
-of_device_id::compatible as that is an array in the struct, not a

-
-From: Ido Schimmel <idosch@mellanox.com>
-
-[ Upstream commit 9d45deb04c59b628b21fc5014aff4f9a1d38f969 ]
-
-When multicast snooping is enabled, the Linux bridge resorts to flooding
-unregistered multicast packets to all ports only in case it did not
-detect a querier in the network.
-
-The above condition is not reflected to underlying drivers, which is
-especially problematic in IPv6 environments, as multicast snooping is
-enabled by default and since neighbour solicitation packets might be
-treated as unregistered multicast packets in case there is no
-corresponding MDB entry.
-
-Until the Linux bridge reflects its querier state to underlying drivers,
-simply treat unregistered multicast packets as broadcast and allow them
-to reach their destination.

-Subject: mm: fix races between address_space dereference and free in page_evicatable
-
-From: Huang Ying <ying.huang@intel.com>
-
-[ Upstream commit e92bb4dd9673945179b1fc738c9817dd91bfb629 ]
-
-When page_mapping() is called and the mapping is dereferenced in
-page_evicatable() through shrink_active_list(), it is possible for the
-inode to be truncated and the embedded address space to be freed at the
-same time. This may lead to the following race.
-
-CPU1 CPU2
-
-truncate(inode) shrink_active_list()
- ... page_evictable(page)
- truncate_inode_page(mapping, page);
- delete_from_page_cache(page)
- spin_lock_irqsave(&mapping->tree_lock, flags);
- __delete_from_page_cache(page, NULL)
- page_cache_tree_delete(..)
- ... mapping = page_mapping(page);
- page->mapping = NULL;
- ...
- spin_unlock_irqrestore(&mapping->tree_lock, flags);
- page_cache_free_page(mapping, page)
- put_page(page)
- if (put_page_testzero(page)) -> false
-- inode now has no pages and can be freed including embedded address_space
-
- mapping_unevictable(mapping)
- test_bit(AS_UNEVICTABLE, &mapping->flags);
-- we've dereferenced mapping which is potentially already free.
-
-Similar race exists between swap cache freeing and page_evicatable()
-too.
-
-The address_space in inode and swap cache will be freed after a RCU
-grace period. So the races are fixed via enclosing the page_mapping()
-and address_space usage in rcu_read_lock/unlock(). Some comments are
-added in code to make it clear what is protected by the RCU read lock.

-Subject: mm/kmemleak.c: wait for scan completion before disabling free
-
-From: Vinayak Menon <vinmenon@codeaurora.org>
-
-[ Upstream commit 914b6dfff790544d9b77dfd1723adb3745ec9700 ]
-
-A crash is observed when kmemleak_scan accesses the object->pointer,
-likely due to the following race.
-
- TASK A TASK B TASK C
- kmemleak_write
- (with "scan" and
- NOT "scan=on")
- kmemleak_scan()
- create_object
- kmem_cache_alloc fails
- kmemleak_disable
- kmemleak_do_cleanup
- kmemleak_free_enabled = 0
- kfree
- kmemleak_free bails out
- (kmemleak_free_enabled is 0)
- slub frees object->pointer
- update_checksum
- crash - object->pointer
- freed (DEBUG_PAGEALLOC)
-
-kmemleak_do_cleanup waits for the scan thread to complete, but not for
-direct call to kmemleak_scan via kmemleak_write. So add a wait for
-kmemleak_scan completion before disabling kmemleak_free, and while at it
-fix the comment on stop_scan_thread.

-Subject: mm/ksm: fix interaction with THP
-
-From: Claudio Imbrenda <imbrenda@linux.vnet.ibm.com>
-
-[ Upstream commit 77da2ba0648a4fd52e5ff97b8b2b8dd312aec4b0 ]
-
-This patch fixes a corner case for KSM. When two pages belong or
-belonged to the same transparent hugepage, and they should be merged,
-KSM fails to split the page, and therefore no merging happens.
-
-This bug can be reproduced by:
-* making sure ksm is running (in case disabling ksmtuned)
-* enabling transparent hugepages
-* allocating a THP-aligned 1-THP-sized buffer
- e.g. on amd64: posix_memalign(&p, 1<<21, 1<<21)
-* filling it with the same values
- e.g. memset(p, 42, 1<<21)
-* performing madvise to make it mergeable
- e.g. madvise(p, 1<<21, MADV_MERGEABLE)
-* waiting for KSM to perform a few scans
-
-The expected outcome is that the all the pages get merged (1 shared and
-the rest sharing); the actual outcome is that no pages get merged (1
-unshared and the rest volatile)
-
-The reason of this behaviour is that we increase the reference count
-once for both pages we want to merge, but if they belong to the same
-hugepage (or compound page), the reference counter used in both cases is
-the one of the head of the compound page. This means that
-split_huge_page will find a value of the reference counter too high and
-will fail.
-
-This patch solves this problem by testing if the two pages to merge
-belong to the same hugepage when attempting to merge them. If so, the
-hugepage is split safely. This means that the hugepage is not split if
-not necessary.

-Subject: mm/page_owner: fix recursion bug after changing skip entries
-
-From: Maninder Singh <maninder1.s@samsung.com>
-
-[ Upstream commit 299815a4fba9f3c7a81434dba0072148f1690608 ]
-
-This patch fixes commit 5f48f0bd4e36 ("mm, page_owner: skip unnecessary
-stack_trace entries").
-
-Because if we skip first two entries then logic of checking count value
-as 2 for recursion is broken and code will go in one depth recursion.
-
-so we need to check only one call of _RET_IP(__set_page_owner) while
-checking for recursion.
-
-Current Backtrace while checking for recursion:-
-
- (save_stack) from (__set_page_owner) // (But recursion returns true here)
- (__set_page_owner) from (get_page_from_freelist)
- (get_page_from_freelist) from (__alloc_pages_nodemask)
- (__alloc_pages_nodemask) from (depot_save_stack)
- (depot_save_stack) from (save_stack) // recursion should return true here
- (save_stack) from (__set_page_owner)
- (__set_page_owner) from (get_page_from_freelist)
- (get_page_from_freelist) from (__alloc_pages_nodemask+)
- (__alloc_pages_nodemask) from (depot_save_stack)
- (depot_save_stack) from (save_stack)
- (save_stack) from (__set_page_owner)
- (__set_page_owner) from (get_page_from_freelist)
-
-Correct Backtrace with fix:
-
- (save_stack) from (__set_page_owner) // recursion returned true here
- (__set_page_owner) from (get_page_from_freelist)
- (get_page_from_freelist) from (__alloc_pages_nodemask+)

-Subject: mm, thp: do not cause memcg oom for thp
-
-From: David Rientjes <rientjes@google.com>
-
-[ Upstream commit 9d3c3354bb85bab4d865fe95039443f09a4c8394 ]
-
-Commit 2516035499b9 ("mm, thp: remove __GFP_NORETRY from khugepaged and
-madvised allocations") changed the page allocator to no longer detect
-thp allocations based on __GFP_NORETRY.
-
-It did not, however, modify the mem cgroup try_charge() path to avoid
-oom kill for either khugepaged collapsing or thp faulting. It is never
-expected to oom kill a process to allocate a hugepage for thp; reclaim
-is governed by the thp defrag mode and MADV_HUGEPAGE, but allocations
-(and charging) should fallback instead of oom killing processes.

-Subject: mm: thp: fix potential clearing to referenced flag in page_idle_clear_pte_refs_one()
-
-From: Yang Shi <yang.shi@linux.alibaba.com>
-
-[ Upstream commit f0849ac0b8e072073ec5fcc7fadd05a77434364e ]
-
-For PTE-mapped THP, the compound THP has not been split to normal 4K
-pages yet, the whole THP is considered referenced if any one of sub page
-is referenced.
-
-When walking PTE-mapped THP by pvmw, all relevant PTEs will be checked
-to retrieve referenced bit. But, the current code just returns the
-result of the last PTE. If the last PTE has not referenced, the
-referenced flag will be cleared.
-
-Just set referenced when ptep{pmdp}_clear_young_notify() returns true.

-
-[ Upstream commit ae4745730cf8e693d354ccd4dbaf59ea440c09a9 ]
-
-In some situation vlan packets do not have ethernet headers. One example
-is packets from tun devices. Users can specify vlan protocol in tun_pi
-field instead of IP protocol, and skb_vlan_untag() attempts to untag such
-packets.
-
-skb_vlan_untag() (more precisely, skb_reorder_vlan_header() called by it)
-however did not expect packets without ethernet headers, so in such a case
-size argument for memmove() underflowed and triggered crash.

-Subject: net: Fix vlan untag for bridge and vlan_dev with reorder_hdr off
-
-From: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp>
-
-[ Upstream commit 4bbb3e0e8239f9079bf1fe20b3c0cb598714ae61 ]
-
-When we have a bridge with vlan_filtering on and a vlan device on top of
-it, packets would be corrupted in skb_vlan_untag() called from
-br_dev_xmit().
-
-The problem sits in skb_reorder_vlan_header() used in skb_vlan_untag(),
-which makes use of skb->mac_len. In this function mac_len is meant for
-handling rx path with vlan devices with reorder_header disabled, but in
-tx path mac_len is typically 0 and cannot be used, which is the problem
-in this case.
-
-The current code even does not properly handle rx path (skb_vlan_untag()
-called from __netif_receive_skb_core()) with reorder_header off actually.
-
-In rx path single tag case, it works as follows:
-
-- Before skb_reorder_vlan_header()
-
- mac_header data
- v v
- +-------------------+-------------+------+----
- | ETH | VLAN | ETH |
- | ADDRS | TPID | TCI | TYPE |
- +-------------------+-------------+------+----
- <-------- mac_len --------->
- <------------->
- to be removed
-
-- After skb_reorder_vlan_header()
-
- mac_header data
- v v
- +-------------------+------+----
- | ETH | ETH |
- | ADDRS | TYPE |
- +-------------------+------+----
- <-------- mac_len --------->
-
-This is ok, but in rx double tag case, it corrupts packets:
-
-- Before skb_reorder_vlan_header()
-
- mac_header data
- v v
- +-------------------+-------------+-------------+------+----
- | ETH | VLAN | VLAN | ETH |
- | ADDRS | TPID | TCI | TPID | TCI | TYPE |
- +-------------------+-------------+-------------+------+----
- <--------------- mac_len ---------------->
- <------------->
- should be removed
- <--------------------------->
- actually will be removed
-
-- After skb_reorder_vlan_header()
-
- mac_header data
- v v
- +-------------------+------+----
- | ETH | ETH |
- | ADDRS | TYPE |
- +-------------------+------+----
- <--------------- mac_len ---------------->
-
-So, two of vlan tags are both removed while only inner one should be
-removed and mac_header (and mac_len) is broken.
-
-skb_vlan_untag() is meant for removing the vlan header at (skb->data - 2),
-so use skb->data and skb->mac_header to calculate the right offset.

-tcf_skbmod_init() can fail after the idr has been successfully reserved.
-When this happens, every subsequent attempt to configure skbmod rules

-Fix this in tcf_skbmod_init(), ensuring that tcf_idr_release() is called
-on the error path when the idr has been reserved, but not yet inserted.
-Also, don't test 'ovr' in the error path, to avoid a 'replace' failure
-implicitly become a 'delete' that leaks refcount in act_skbmod module:

-act_bpf correctly refuses to install the first TC rule, because 31 is not
-a valid instruction. However, it refuses to install the second TC rule,
-even if the BPF code is correct. Furthermore, it's no more possible to
-install any other rule having the same value of 'index' until act_bpf
-module is unloaded/inserted again. After the idr has been reserved, call
-tcf_idr_release() instead of tcf_idr_cleanup(), to fix this issue.

-Subject: net: stmmac: ensure that the MSS desc is the last desc to set the own bit
-
-From: Niklas Cassel <niklas.cassel@axis.com>
-
-[ Upstream commit 15d2ee42a3087089e73ad52fd8c1b37ab496b87c ]
-
-A dma_wmb() is used to guarantee the ordering, with respect to
-other writes, to cache coherent DMA memory.
-
-There is a dma_wmb() in prepare_tx_desc()/prepare_tso_tx_desc() which
-ensures that TDES0/1/2 is written before TDES3 (which contains the own
-bit), for First Desc.
-
-However, in the rare case that MSS changes, there will be a MSS
-context descriptor in front of the regular DMA descriptors:
-
-<MSS desc> <- DMA Next Descriptor
-<First Desc>
-<desc n>
-<Last Desc>
-
-Thus, for this special case, we need a dma_wmb()
-after prepare_tso_tx_desc()/before writing the own bit to the MSS desc,
-so that we flush the write to TDES3 for First Desc,
-in order to ensure that the MSS descriptor is the last descriptor to
-set the own bit.

-
-The link to the pdf containing the algorithm description is now a
-dead link; it seems http://www.ifp.illinois.edu/~srikant/ has been
-moved to https://sites.google.com/a/illinois.edu/srikant/ and none of
-the original papers can be found there...
-
-I have replaced it with the only working copy I was able to find.
-
-n.b. there is also a copy available at:
-
-http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.296.6350&rep=rep1&type=pdf
-
-However, this seems to only be a *cached* version, so I am unsure
-exactly how reliable that link can be expected to remain over time
-and have decided against using that one.

-
-From: Eric Dumazet <edumazet@google.com>
-
-[ Upstream commit 2695578b896aea472b2c0dcbe9d92daa71738484 ]
-
-Marek reported a LOCKDEP issue occurring on 32bit host,
-that we tracked down to the fact that usbnet could either
-run from soft or hard irqs.
-
-This patch adds u64_stats_update_begin_irqsave() and
-u64_stats_update_end_irqrestore() helpers to solve this case.

-
-From: Florian Westphal <fw@strlen.de>
-
-[ Upstream commit 47b7e7f82802dced3ac73658bf4b77584a63063f ]
-
-"fib" starts to behave strangely when an ipv6 default route is
-added - the FIB lookup returns a route using 'oif' in this case.
-
-This behaviour was inherited from ip6tables rpfilter so change

-skb_header_pointer will copy data into a buffer if data is non linear,

-nf_sk_lookup_slow_v{4,6} always copies data of size udphdr but later

-
-[ Upstream commit 467c77d4cbefaaf65e2f44fe102d543a52fcae5b ]
-
-Yet another "incompatible" Samsung NVMe SSD 960 EVO and Asus motherboard
-combination. 960 EVO device disappears from PCIe bus within few minutes
-after boot-up when APST is in use and never gets back. Forcing
-NVME_QUIRK_NO_APST is the only way to make this drive work with this
-particular motherboard. NVME_QUIRK_NO_DEEPEST_PS doesn't work, upgrading
-motherboard's BIOS didn't help either.
-Since this is a desktop motherboard, the only drawback of not using APST
-is increased device temperature.

-Subject: nvme-pci: Fix EEH failure on ppc
-
-From: Wen Xiong <wenxiong@linux.vnet.ibm.com>
-
-[ Upstream commit 651438bb0af5213f1f70d66e75bf11d08cb5537a ]
-
-Triggering PPC EEH detection and handling requires a memory mapped read
-failure. The NVMe driver removed the periodic health check MMIO, so
-there's no early detection mechanism to trigger the recovery. Instead,
-the detection now happens when the nvme driver handles an IO timeout
-event. This takes the pci channel offline, so we do not want the driver
-to proceed with escalating its own recovery efforts that may conflict
-with the EEH handler.
-
-This patch ensures the driver will observe the channel was set to offline
-after a failed MMIO read and resets the IO timer so the EEH handler has
-a chance to recover the device.

-
-From: Ming Lei <ming.lei@redhat.com>

-
-84676c1f21 ("genirq/affinity: assign vectors to all possible CPUs")
-has switched to do irq vectors spread among all possible CPUs, so
-pass num_possible_cpus() as max vecotrs to be assigned.
-
-For example, in a 8 cores system, 0~3 online, 4~8 offline/not present,
-see 'lscpu':
-
- [ming@box]$lscpu
- Architecture: x86_64
- CPU op-mode(s): 32-bit, 64-bit
- Byte Order: Little Endian

- Thread(s) per core: 1
- Core(s) per socket: 2
- Socket(s): 2
- NUMA node(s): 2
- ...
- NUMA node0 CPU(s): 0-3
- NUMA node1 CPU(s):
- ...
-
-1) before this patch, follows the allocated vectors and their affinity:
- irq 47, cpu list 0,4
- irq 48, cpu list 1,6
- irq 49, cpu list 2,5
- irq 50, cpu list 3,7
-
-2) after this patch, follows the allocated vectors and their affinity:

-Subject: ocfs2/dlm: don't handle migrate lockres if already in shutdown
-
-From: Jun Piao <piaojun@huawei.com>
-
-[ Upstream commit bb34f24c7d2c98d0c81838a7700e6068325b17a0 ]
-
-We should not handle migrate lockres if we are already in
-'DLM_CTXT_IN_SHUTDOWN', as that will cause lockres remains after leaving
-dlm domain. At last other nodes will get stuck into infinite loop when
-requsting lock from us.
-
-The problem is caused by concurrency umount between nodes. Before
-receiveing N1's DLM_BEGIN_EXIT_DOMAIN_MSG, N2 has picked up N1 as the
-migrate target. So N2 will continue sending lockres to N1 even though
-N1 has left domain.
-
- N1 N2 (owner)
- touch file
-
- access the file,
- and get pr lock
-
- begin leave domain and
- pick up N1 as new owner
-
- begin leave domain and
- migrate all lockres done
-
- begin migrate lockres to N1
-
- end leave domain, but
- the lockres left
- unexpectedly, because
- migrate task has passed

-Subject: parisc/pci: Switch LBA PCI bus from Hard Fail to Soft Fail mode
-
-From: Helge Deller <deller@gmx.de>
-
-[ Upstream commit b845f66f78bf42a4ce98e5cfe0e94fab41dd0742 ]
-
-Carlo Pisani noticed that his C3600 workstation behaved unstable during heavy
-I/O on the PCI bus with a VIA VT6421 IDE/SATA PCI card.
-
-To avoid such instability, this patch switches the LBA PCI bus from Hard Fail
-mode into Soft Fail mode. In this mode the bus will return -1UL for timed out
-MMIO transactions, which is exactly how the x86 (and most other architectures)
-PCI busses behave.
-
-This patch is based on a proposal by Grant Grundler and Kyle McMartin 10
-years ago:

-Subject: PCI: Restore config space on runtime resume despite being unbound
-
-From: "Rafael J. Wysocki" <rjw@rjwysocki.net>
-
-[ Upstream commit 5775b843a619b3c93f946e2b55a208d9f0f48b59 ]
-
-We leave PCI devices not bound to a driver in D0 during runtime suspend.
-But they may have a parent which is bound and can be transitioned to
-D3cold at runtime. Once the parent goes to D3cold, the unbound child
-may go to D3cold as well. When the child goes to D3cold, its internal
-state, including configuration of BARs, MSI, ASPM, MPS, etc., is lost.
-
-One example are recent hybrid graphics laptops which cut power to the
-discrete GPU when the root port above it goes to ACPI power state D3.
-Users may provoke this by unbinding the GPU driver and allowing runtime
-PM on the GPU via sysfs: The PM core will then treat the GPU as
-"suspended", which in turn allows the root port to runtime suspend,
-causing the power resources listed in its _PR3 object to be powered off.
-The GPU's BARs will be uninitialized when a driver later probes it.
-
-Another example are hybrid graphics laptops where the GPU itself (rather
-than the root port) is capable of runtime suspending to D3cold. If the
-GPU's integrated HDA controller is not bound and the GPU's driver
-decides to runtime suspend to D3cold, the HDA controller's BARs will be
-uninitialized when a driver later probes it.
-
-Fix by saving and restoring config space over a runtime suspend cycle
-even if the device is not bound.

-Subject: PCMCIA / PM: Avoid noirq suspend aborts during suspend-to-idle
-
-From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>
-
-[ Upstream commit dbdd0f58fd2cdde5cf945c9da67a2d52d32ba550 ]
-
-There is a problem with PCMCIA system resume callbacks with respect
-to suspend-to-idle in which the ->suspend_noirq() callback may be
-invoked after the ->resume_noirq() one without resuming the system
-entirely in some cases. This doesn't work for PCMCIA because of
-the lack of symmetry between its system suspend and system resume
-"noirq" callbacks.
-
-The system resume handling in PCMCIA is split between
-socket_early_resume() and socket_late_resume() which are called in
-different phases of system resume and both need to run for
-socket_suspend() (invoked by the system suspend "noirq" callback)
-to work. Specifically, socket_suspend() returns an error when
-called after socket_early_resume() without socket_late_resume(),
-so if the suspend-to-idle core detects a spurious wakeup event and
-attempts to put the system back to sleep, that is aborted by the
-error coming from socket_suspend().
-
-Avoid that by using a new socket state flag, SOCKET_IN_RESUME,
-to indicate that socket_early_resume() has already run for the
-socket in which case socket_suspend() will do minimum handling
-and return 0.
-
-This change has been tested on my venerable Toshiba Portege R500
-(which is where the problem has been discovered in the first place),
-but admittedly I have no PCMCIA cards to test along with the socket
-itself.

-Subject: perf/cgroup: Fix child event counting bug
-
-From: Song Liu <songliubraving@fb.com>
-
-[ Upstream commit c917e0f259908e75bd2a65877e25f9d90c22c848 ]
-
-When a perf_event is attached to parent cgroup, it should count events
-for all children cgroups:
-
- parent_group <---- perf_event
- \
- - child_group <---- process(es)
-
-However, in our tests, we found this perf_event cannot report reliable
-results. Here is an example case:
-
- # create cgroups
- mkdir -p /sys/fs/cgroup/p/c
- # start perf for parent group
- perf stat -e instructions -G "p"
-
- # on another console, run test process in child cgroup:
- stressapptest -s 2 -M 1000 & echo $! > /sys/fs/cgroup/p/c/cgroup.procs
-
- # after the test process is done, stop perf in the first console shows
-
- <not counted> instructions p
-
-The instruction should not be "not counted" as the process runs in the
-child cgroup.
-
-We found this is because perf_event->cgrp and cpuctx->cgrp are not
-identical, thus perf_event->cgrp are not updated properly.
-
-This patch fixes this by updating perf_cgroup properly for ancestor
-cgroup(s).

-Subject: perf clang: Add support for recent clang versions
-
-From: Sandipan Das <sandipan@linux.vnet.ibm.com>
-
-[ Upstream commit 7854e499f33fd9c7e63288692ffb754d9b1d02fd ]
-
-The clang API calls used by perf have changed in recent releases and
-builds succeed with libclang-3.9 only. This introduces compatibility
-with libclang-4.0 and above.
-
-Without this patch, we will see the following compilation errors with
-libclang-4.0+:
-
- util/c++/clang.cpp: In function ‘clang::CompilerInvocation* perf::createCompilerInvocation(llvm::opt::ArgStringList, llvm::StringRef&, clang::DiagnosticsEngine&)’:
- util/c++/clang.cpp:62:33: error: ‘IK_C’ was not declared in this scope
- Opts.Inputs.emplace_back(Path, IK_C);
- ^~~~

- ^~~~~~~~~~~~~
-
-Committer testing:
-
-Tested on Fedora 27 after installing the clang-devel and llvm-devel
-packages, versions:
-
- # rpm -qa | egrep llvm\|clang
- llvm-5.0.1-6.fc27.x86_64
- clang-libs-5.0.1-5.fc27.x86_64

-
-Make sure you don't have some older version lying around in /usr/local,

-
- $ make LIBCLANGLLVM=1 -C tools/perf install-bin

-Subject: perf/core: Fix installing cgroup events on CPU
-
-From: "leilei.lin" <leilei.lin@alibaba-inc.com>
-
-[ Upstream commit 33801b94741d6c3be9713c10aa627477216c21e2 ]
-
-There's two problems when installing cgroup events on CPUs: firstly
-list_update_cgroup_event() only tries to set cpuctx->cgrp for the
-first event, if that mismatches on @cgrp we'll not try again for later
-additions.
-
-Secondly, when we install a cgroup event into an active context, only
-issue an event reprogram when the event matches the current cgroup
-context. This avoids a pointless event reprogramming.

- perf_output_read_group()
- leader->pmu->read()
-
-Which results in doing a pmu::read() on an !ACTIVE event.
-
-I _think_ this is 'new' since we added attr.inherit_stat, which added
-the perf_event_read_event() to the exit path, without that
-perf_event_read_output() would only trigger from samples and for
-@event to trigger a sample, it's leader _must_ be ACTIVE too.
-
-Still, adding this check makes it consistent with the @sub case for
-the siblings.

-Subject: perf record: Fix crash in pipe mode
-
-From: Jiri Olsa <jolsa@kernel.org>
-
-[ Upstream commit ad46e48c65fa1f204fa29eaff1b91174d314a94b ]
-
-Currently we can crash perf record when running in pipe mode, like:
-
- $ perf record ls | perf report
- # To display the perf.data header info, please use --header/--header-only options.
- #
- perf: Segmentation fault
- Error:
- The - file has no samples!
-
-The callstack of the crash is:
-
- 0x0000000000515242 in perf_event__synthesize_event_update_name
- 3513 ev = event_update_event__new(len + 1, PERF_EVENT_UPDATE__NAME, evsel->id[0]);
- (gdb) bt
- #0 0x0000000000515242 in perf_event__synthesize_event_update_name
- #1 0x00000000005158a4 in perf_event__synthesize_extra_attr
- #2 0x0000000000443347 in record__synthesize
- #3 0x00000000004438e3 in __cmd_record
- #4 0x000000000044514e in cmd_record
- #5 0x00000000004cbc95 in run_builtin
- #6 0x00000000004cbf02 in handle_internal_command
- #7 0x00000000004cc054 in run_argv
- #8 0x00000000004cc422 in main
-
-The reason of the crash is that the evsel does not have ids array
-allocated and the pipe's synthesize code tries to access it.
-
-We don't force evsel ids allocation when we have single event, because
-it's not needed. However we need it when we are in pipe mode even for
-single event as a key for evsel update event.
-
-Fixing this by forcing evsel ids allocation event for single event, when
-we are in pipe mode.

-For the cumulative output, we allocate the he_cache array based on the
---max-stack option value and populate it with data from 'callchain_cursor'.
-
-The --max-stack option value does not ensure now the limit for number of
-callchain_cursor nodes, so the cumulative iter code will allocate smaller array
-than it's actually needed and cause above corruption.
-
-I think the --max-stack limit does not apply here anyway, because we add
-callchain data as normal hist entries, while the --max-stack control the limit
-of single entry callchain depth.
-
-Using the callchain_cursor.nr as he_cache array count to fix this. Also
-removing struct hist_entry_iter::max_stack, because there's no longer any use
-for it.
-
-We need more fixes to ensure that the branch stack code follows properly the
-logic of --max-stack, which is not the case at the moment.

-
-When we use perf report interactive annotate view, we can see

-Committer notes:
-
-Please note that only from LBRv5 (according to Jiri) onwards, i.e. >=
-Skylake is that we'll have the cycles counts in each branch record
-entry, so to see the Cycles and IPC columns, and be able to test this
-patch, one need a capable hardware.
-
-While applying this I first tested it on a Broadwell class machine and
-couldn't get those columns, will add code to the annotate browser to
-warn the user about that, i.e. you have branch records, but no cycles,
-use a more recent hardware to get the cycles and IPC columns.

-It turns out that a NULL pointer is referenced. Here are the
-function calls:
-
- ...
- cmd_stat()
- +---> add_default_attributes()
- +---> parse_events(evsel_list, transaction_attrs, NULL);
- 3rd parameter set to NULL
-
-Function parse_events(xx, xx, struct parse_events_error *err) dives
-into a bison generated scanner and creates
-parser state information for it first:
-
- struct parse_events_state parse_state = {
- .list = LIST_HEAD_INIT(parse_state.list),
- .idx = evlist->nr_entries,
- .error = err, <--- NULL POINTER !!!
- .evlist = evlist,
- };
-
-Now various functions inside the bison scanner are called to end up in
-__parse_events_add_pmu(struct parse_events_state *parse_state, ..) with
-first parameter being a pointer to above structure definition.
-
-Now the PMU event name is not found (because being executed in a VM) and
-this function tries to create an error message with
-
- asprintf(&parse_state->error.str, ....)
-
-which references a NULL pointer and dumps core.
-
-Fix this by providing a pointer to the necessary error information
-instead of NULL. Technically only the else part is needed to avoid the
-core dump, just lets be safe...

-
-Using Fedora 27 and latest Linux kernel the test case
-trace+probe_libc_inet_pton.sh fails again on s390. This time is the
-inlining of functions which does not match. After an update of the
-glibc (from 2.26-16 to 2.26-24) the output is different
-
-The expected output is:
-
- __inet_pton (/usr/lib64/libc-2.26.so)
- gaih_inet (inlined)
- ....
-
-The actual output is:
-
- 1 packets transmitted, 1 received, 0% packet loss, time 0ms
- rtt min/avg/max/mdev = 0.061/0.061/0.061/0.000 ms
- 0.000 probe_libc:inet_pton:(3ffb2140448))
- __inet_pton (inlined)
- gaih_inet.constprop.7 (/usr/lib64/libc-2.26.so)
- ...
-
-Fix this by being less strict on 'inlined' verses library name and
-accept both

-Subject: perf tests: Fix dwarf unwind for stripped binaries
-
-From: Jiri Olsa <jolsa@kernel.org>
-
-[ Upstream commit fdf7c49c200d1b9909e2204cec5bd68b48605c71 ]
-
-When we strip the perf binary, dwarf unwind test stop
-to work. The reason is that strip will remove static
-function symbols, which we need to check for unwind.
-
-This change will keep this test working in cases where
-the global symbols are put into dynamic symbol table,
-which is the case on x86. It still won't work on powerpc.
-
-Making those 5 local functions global, and adding
-'test_dwarf_unwind__' to their names.
-
-Committer testing:

-Subject: perf tests: Use arch__compare_symbol_names to compare symbols
-
-From: Jiri Olsa <jolsa@kernel.org>
-
-[ Upstream commit ab6e9a99345131cd8e54268d1d0dc04a33f7ed11 ]
-
-The symbol search called by machine__find_kernel_symbol_by_name is using
-internally arch__compare_symbol_names function to compare 2 symbol
-names, because different archs have different ways of comparing symbols.
-Mostly for skipping '.' prefixes and similar.
-
-In test 1 when we try to find matching symbols in kallsyms and vmlinux,
-by address and by symbol name. When either is found we compare the pair
-symbol names by simple strcmp, which is not good enough for reasons
-explained in previous paragraph.
-
-On powerpc this can cause lockup, because even thought we found the
-pair, the compared names are different and don't match simple strcmp.
-Following code path is executed, that leads to lockup:
-
- - we find the pair in kallsyms by sym->start
-next_pair:
- - we compare the names and it fails
- - we find the pair by sym->name
- - the pair addresses match so we call goto next_pair
- because we assume the names match in this case

-Subject: perf/x86/intel: Fix event update for auto-reload
-
-From: Kan Liang <kan.liang@linux.intel.com>
-
-[ Upstream commit d31fc13fdcb20e1c317f9a7dd6273c18fbd58308 ]
-
-There is a bug when reading event->count with large PEBS enabled.
-
-Here is an example:
-
- # ./read_count
- 0x71f0
- 0x122c0
- 0x1000000001c54
- 0x100000001257d
- 0x200000000bdc5
-
-In fixed period mode, the auto-reload mechanism could be enabled for
-PEBS events, but the calculation of event->count does not take the
-auto-reload values into account.
-
-Anyone who reads event->count will get the wrong result, e.g x86_pmu_read().
-
-This bug was introduced with the auto-reload mechanism enabled since
-commit:
-
- 851559e35fd5 ("perf/x86/intel: Use the PEBS auto reload mechanism when possible")
-
-Introduce intel_pmu_save_and_restart_reload() to calculate the
-event->count only for auto-reload.
-
-Since the counter increments a negative counter value and overflows on
-the sign switch, giving the interval:
-
- [-period, 0]
-
-the difference between two consequtive reads is:
-
- A) value2 - value1;
- when no overflows have happened in between,
- B) (0 - value1) + (value2 - (-period));
- when one overflow happened in between,
- C) (0 - value1) + (n - 1) * (period) + (value2 - (-period));
- when @n overflows happened in between.
-
-Here A) is the obvious difference, B) is the extension to the discrete
-interval, where the first term is to the top of the interval and the
-second term is from the bottom of the next interval and C) the extension
-to multiple intervals, where the middle term is the whole intervals
-covered.
-
-The equation for all cases is:
-
- value2 - value1 + n * period
-
-Previously the event->count is updated right before the sample output.
-But for case A, there is no PEBS record ready. It needs to be specially
-handled.
-
-Remove the auto-reload code from x86_perf_event_set_period() since
-we'll not longer call that function in this case.

-Subject: perf/x86/intel: Fix large period handling on Broadwell CPUs
-
-From: Kan Liang <kan.liang@linux.intel.com>
-
-[ Upstream commit f605cfca8c39ffa2b98c06d2b9f30ba64f1e54e3 ]
-
-Large fixed period values could be truncated on Broadwell, for example:
-
- perf record -e cycles -c 10000000000
-
-Here the fixed period is 0x2540BE400, but the period which finally applied is
-0x540BE400 - which is wrong.
-
-The reason is that x86_pmu::limit_period() uses an u32 parameter, so the
-high 32 bits of 'period' get truncated.
-
-This bug was introduced in:
-
- commit 294fe0f52a44 ("perf/x86/intel: Add INST_RETIRED.ALL workarounds")
-
-It's safe to use u64 instead of u32:
-
- - Although the 'left' is s64, the value of 'left' must be positive when
- calling limit_period().
-
- - bdw_limit_period() only modifies the lowest 6 bits, it doesn't touch
- the higher 32 bits.

-Subject: perf/x86/intel: Fix linear IP of PEBS real_ip on Haswell and later CPUs
-
-From: Stephane Eranian <eranian@google.com>
-
-[ Upstream commit 71eb9ee9596d8df3d5723c3cfc18774c6235e8b1 ]
-
-this patch fix a bug in how the pebs->real_ip is handled in the PEBS
-handler. real_ip only exists in Haswell and later processor. It is
-actually the eventing IP, i.e., where the event occurred. As opposed
-to the pebs->ip which is the PEBS interrupt IP which is always off
-by one.
-
-The problem is that the real_ip just like the IP needs to be fixed up
-because PEBS does not record all the machine state registers, and
-in particular the code segement (cs). This is why we have the set_linear_ip()
-function. The problem was that set_linear_ip() was only used on the pebs->ip
-and not the pebs->real_ip.
-
-We have profiles which ran into invalid callstacks because of this.
-Here is an example:
-
- ..... 0: ffffffffffffff80 recent entry, marker kernel v
- ..... 1: 000000000040044d <= user address in kernel space!
- ..... 2: fffffffffffffe00 marker enter user v
- ..... 3: 000000000040044d
- ..... 4: 00000000004004b6 oldest entry
-
-Debugging output in get_perf_callchain():
-
- [ 857.769909] CALLCHAIN: CPU8 ip=40044d regs->cs=10 user_mode(regs)=0
-
-The problem is that the kernel entry in 1: points to a user level
-address. How can that be?
-
-The reason is that with PEBS sampling the instruction that caused the event
-to occur and the instruction where the CPU was when the interrupt was posted
-may be far apart. And sometime during that time window, the privilege level may
-change. This happens, for instance, when the PEBS sample is taken close to a
-kernel entry point. Here PEBS, eventing IP (real_ip) captured a user level
-instruction. But by the time the PMU interrupt fired, the processor had already
-entered kernel space. This is why the debug output shows a user address with
-user_mode() false.
-
-The problem comes from PEBS not recording the code segment (cs) register.
-The register is used in x86_64 to determine if executing in kernel vs user
-space. This is okay because the kernel has a software workaround called
-set_linear_ip(). But the issue in setup_pebs_sample_data() is that
-set_linear_ip() is never called on the real_ip value when it is available
-(Haswell and later) and precise_ip > 1.
-
-This patch fixes this problem and eliminates the callchain discrepancy.
-
-The patch restructures the code around set_linear_ip() to minimize the number
-of times the IP has to be set.

-Subject: pinctrl: devicetree: Fix dt_to_map_one_config handling of hogs
-
-From: Richard Fitzgerald <rf@opensource.cirrus.com>
-
-[ Upstream commit b89405b6102fcc3746f43697b826028caa94c823 ]
-
-When dt_to_map_one_config() is called with a pinctrl_dev passed
-in, it should only be using this if the node being looked up
-is a hog. The code was always using the passed pinctrl_dev
-without checking whether the dt node referred to it.
-
-A pin controller can have pinctrl-n dependencies on other pin
-controllers in these cases:
-
-- the pin controller hardware is external, for example I2C, so
- needs other pin controller(s) to be setup to communicate with
- the hardware device.
-
-- it is a child of a composite MFD so its of_node is shared with
- the parent MFD and other children of that MFD. Any part of that
- MFD could have dependencies on other pin controllers.
-
-Because of this, dt_to_map_one_config() can't assume that if it
-has a pinctrl_dev passed in then the node it looks up must be
-a hog. It could be a reference to some other pin controller.

-Subject: pinctrl: mcp23s08: spi: Fix regmap debugfs entries
-
-From: "Jan Kundrát" <jan.kundrat@cesnet.cz>
-
-[ Upstream commit 9b3e4207661e67f04c72af15e29f74cd944f5964 ]
-
-The SPI version of this chip allows several devices to be present on the
-same SPI bus via a local address. If this is in action and if the kernel
-has debugfs, however, the code attempts to create duplicate entries for
-the regmap's debugfs:
-
- mcp23s08 spi1.1: Failed to create debugfs directory
-
-This patch simply assigns a local name matching the device logical
-address to the `struct regmap_config`.
-
-No changes are needed for MCP23S18 because that device does not support
-any logical addressing. Similarly, I2C devices do not need any action,
-either, because they are already different in their I2C address.
-
-A similar problem is present for the pinctrl debugfs instance, but that
-one is not addressed by this patch.

-Subject: PKCS#7: fix direct verification of SignerInfo signature
-
-From: Eric Biggers <ebiggers@google.com>
-
-[ Upstream commit 6459ae386699a5fe0dc52cf30255f75274fa43a4 ]
-
-If none of the certificates in a SignerInfo's certificate chain match a
-trusted key, nor is the last certificate signed by a trusted key, then
-pkcs7_validate_trust_one() tries to check whether the SignerInfo's
-signature was made directly by a trusted key. But, it actually fails to
-set the 'sig' variable correctly, so it actually verifies the last
-signature seen. That will only be the SignerInfo's signature if the
-certificate chain is empty; otherwise it will actually be the last
-certificate's signature.
-
-This is not by itself a security problem, since verifying any of the
-certificates in the chain should be sufficient to verify the SignerInfo.
-Still, it's not working as intended so it should be fixed.
-
-Fix it by setting 'sig' correctly for the direct verification case.

-Subject: powerpc/64s: sreset panic if there is no debugger or crash dump handlers
-
-From: Nicholas Piggin <npiggin@gmail.com>
-
-[ Upstream commit d40b6768e45bd9213139b2d91d30c7692b6007b1 ]
-
-system_reset_exception does most of its own crash handling now,
-invoking the debugger or crash dumps if they are registered. If not,
-then it goes through to die() to print stack traces, and then is
-supposed to panic (according to comments).
-
-However after die() prints oopses, it does its own handling which
-doesn't allow system_reset_exception to panic (e.g., it may just
-kill the current process). This patch causes sreset exceptions to
-return from die after it prints messages but before acting.
-
-This also stops die from invoking the debugger on 0x100 crashes.
-system_reset_exception similarly calls the debugger. It had been
-thought this was harmless (because if the debugger was disabled,
-neither call would fire, and if it was enabled the first call
-would return). However in some cases like xmon 'X' command, the
-debugger returns 0, which currently causes it to be entered
-again (first in system_reset_exception, then in die), which is
-confusing.

-
-BUG: sleeping function called from invalid context
-
-Though interrupts get enabled back but it happens bit later after

-
-In mpic_physmask() we loop over all CPUs up to 32, then get the hard
-SMP processor id of that CPU.
-
-Currently that's possibly walking off the end of the paca array, but
-in a future patch we will change the paca array to be an array of
-pointers, and in that case we will get a NULL for missing CPUs and
-oops. eg:
-
- Unable to handle kernel paging request for data at address 0x88888888888888b8
- Faulting instruction address: 0xc00000000004e380
- Oops: Kernel access of bad area, sig: 11 [#1]
- ...
- NIP .mpic_set_affinity+0x60/0x1a0
- LR .irq_do_set_affinity+0x48/0x100
-
-Fix it by checking the CPU is possible, this also fixes the code if
-there are gaps in the CPU numbering which probably never happens on
-mpic systems but who knows.

-Subject: powerpc/perf: Fix kernel address leak via sampling registers
-
-From: Michael Ellerman <mpe@ellerman.id.au>
-
-[ Upstream commit e1ebd0e5b9d0a10ba65e63a3514b6da8c6a5a819 ]
-
-Current code in power_pmu_disable() does not clear the sampling
-registers like Sampling Instruction Address Register (SIAR) and
-Sampling Data Address Register (SDAR) after disabling the PMU. Since
-these are userspace readable and could contain kernel addresses, add
-code to explicitly clear the content of these registers.
-
-Also add a "context synchronizing instruction" to enforce no further
-updates to these registers as suggested by Power ISA v3.0B. From
-section 9.4, on page 1108:
-
- "If an mtspr instruction is executed that changes the value of a
- Performance Monitor register other than SIAR, SDAR, and SIER, the
- change is not guaranteed to have taken effect until after a
- subsequent context synchronizing instruction has been executed (see
- Chapter 11. "Synchronization Requirements for Context Alterations"
- on page 1133)."

-Subject: powerpc/powernv/npu: Fix deadlock in mmio_invalidate()
-
-From: Alistair Popple <alistair@popple.id.au>
-
-[ Upstream commit 2b74e2a9b39df40a2b489af2d24079617c61ee0e ]
-
-When sending TLB invalidates to the NPU we need to send extra flushes due
-to a hardware issue. The original implementation would lock the all the
-ATSD MMIO registers sequentially before unlocking and relocking each of
-them sequentially to do the extra flush.
-
-This introduced a deadlock as it is possible for one thread to hold one
-ATSD register whilst waiting for another register to be freed while the
-other thread is holding that register waiting for the one in the first
-thread to be freed.
-
-For example if there are two threads and two ATSD registers:
-
- Thread A Thread B
- ----------------------
- Acquire 1
- Acquire 2
- Release 1 Acquire 1
- Wait 1 Wait 2
-
-Both threads will be stuck waiting to acquire a register resulting in an
-RCU stall warning or soft lockup.
-
-This patch solves the deadlock by refactoring the code to ensure registers
-are not released between flushes and to ensure all registers are either
-acquired or released together and in order.
-

-Subject: powerpc/xmon: Setup debugger hooks when first break-point is set
-
-From: Vaibhav Jain <vaibhav@linux.vnet.ibm.com>
-
-[ Upstream commit e1368d0c9edbc366e45216e7295fd61ae55c2b12 ]
-
-Presently sysrq key for xmon('x') is registered during kernel init
-irrespective of the value of kernel param 'xmon'. Thus xmon is enabled
-even if 'xmon=off' is passed on the kernel command line. However this
-doesn't enable the kernel debugger hooks needed for instruction or
-data breakpoints. Thus when a break-point is hit with xmon=off a
-kernel oops of the form below is reported:
-
- Oops: Exception in kernel mode, sig: 5 [#1]
- < snip >
- Trace/breakpoint trap
-
-To fix this the patch checks and enables debugger hooks when an
-instruction or data break-point is set via xmon console.

-Subject: qed: Free RoCE ILT Memory on rmmod qedr
-
-From: Michal Kalderon <Michal.Kalderon@cavium.com>
-
-[ Upstream commit 9de506a547c0d172d13a91d69b1a399e6a2c0efa ]
-
-Rdma requires ILT Memory to be allocated for it's QPs.
-Each ILT entry points to a page used by several Rdma QPs.
-To avoid allocating all the memory in advance, the rdma
-implementation dynamically allocates memory as more QPs are
-added, however it does not dynamically free the memory.
-The memory should have been freed on rmmod qedr, but isn't.
-This patch adds the memory freeing on rmmod qedr (currently
-it will be freed with qed is removed).
-
-An outcome of this bug, is that if qedr is unloaded and loaded
-without unloaded qed, there will be no more RoCE traffic.
-
-The reason these are related, is that the logic of detecting the
-first QP ever opened is by asking whether ILT memory for RoCE has
-been allocated.
-
-In addition, this patch modifies freeing of the Task context to
-always use the PROTOCOLID_ROCE and not the protocol passed,
-this is because task context for iWARP and ROCE both use the
-ROCE protocol id, as opposed to the connection context.
-

-Subject: qede: Fix barrier usage after tx doorbell write.
-
-From: Manish Chopra <manish.chopra@cavium.com>
-
-[ Upstream commit b9fc828debc8ac2bb21b5819a44d2aea456f1c95 ]
-
-Since commit c5ad119fb6c09b0297446be05bd66602fa564758
-("net: sched: pfifo_fast use skb_array") driver is exposed
-to an issue where it is hitting NULL skbs while handling TX
-completions. Driver uses mmiowb() to flush the writes to the
-doorbell bar which is a write-combined bar, however on x86
-mmiowb() does not flush the write combined buffer.
-
-This patch fixes this problem by replacing mmiowb() with wmb()
-after the write combined doorbell write so that writes are
-flushed and synchronized from more than one processor.
-
-V1->V2:
--------
-This patch was marked as "superseded" in patchwork.
-(Not really sure for what reason).Resending it as v2.

-QPs that were configured with ack timeout value lower than 1

-
-From: Ka-Cheong Poon <ka-cheong.poon@oracle.com>
-
-[ Upstream commit 84eef2b2187ed73c0e4520cbfeb874e964a0b56a ]
-
-Commit 0933a578cd55 ("rds: tcp: use sock_create_lite() to create the
-accept socket") has a reference counting issue in TCP socket creation
-when accepting a new connection. The code uses sock_create_lite() to
-create a kernel socket. But it does not do __module_get() on the
-socket owner. When the connection is shutdown and sock_release() is
-called to free the socket, the owner's reference count is decremented
-and becomes incorrect. Note that this bug only shows up when the socket
-owner is configured as a kernel module.

-Subject: rtc: hctosys: Ensure system time doesn't overflow time_t
-
-From: Alexandre Belloni <alexandre.belloni@bootlin.com>
-
-[ Upstream commit b3a5ac42ab18b7d1a8f2f072ca0ee76a3b754a43 ]
-
-On 32bit platforms, time_t is still a signed 32bit long. If it is
-overflowed, userspace and the kernel cant agree on the current system time.
-This causes multiple issues, in particular with systemd:
-https://github.com/systemd/systemd/issues/1143
-
-A good workaround is to simply avoid using hctosys which is something I
-greatly encourage as the time is better set by userspace.
-
-However, many distribution enable it and use systemd which is rendering the
-system unusable in case the RTC holds a date after 2038 (and more so after
-2106). Many drivers have workaround for this case and they should be
-eliminated so there is only one place left to fix when userspace is able to
-cope with dates after the 31bit overflow.

-commit 179a502f8c46 ("rtc: snvs: add Freescale rtc-snvs driver") introduces
-the SNVS RTC driver with a function snvs_rtc_enable().

-driver does not currently trap that failure on the probe() path and
-consequently if enabling the RTC fails we encounter a later error spinning
-forever in rtc_write_sync_lp().

-Subject: rxrpc: Don't treat call aborts as conn aborts
-
-From: David Howells <dhowells@redhat.com>
-
-[ Upstream commit 57b0c9d49b94bbeb53649b7fbd264603c1ebd585 ]
-
-If a call-level abort is received for the previous call to complete on a
-connection channel, then that abort is queued for the connection processor
-to handle. Unfortunately, the connection processor then assumes without
-checking that the abort is connection-level (ie. callNumber is 0) and
-distributes it over all active calls on that connection, thereby
-incorrectly aborting them.
-
-Fix this by discarding aborts aimed at a completed call.
-
-Further, discard all packets aimed at a call that's complete if there's
-currently an active call on a channel, since the DATA packets associated
-with the new call automatically terminate the old call.

-Subject: rxrpc: Fix Tx ring annotation after initial Tx failure
-
-From: David Howells <dhowells@redhat.com>
-
-[ Upstream commit 03877bf6a30cca7d4bc3ffabd3c3e9464a7a1a19 ]
-
-rxrpc calls have a ring of packets that are awaiting ACK or retransmission
-and a parallel ring of annotations that tracks the state of those packets.
-If the initial transmission of a packet on the underlying UDP socket fails
-then the packet annotation is marked for resend - but the setting of this
-mark accidentally erases the last-packet mark also stored in the same
-annotation slot. If this happens, a call won't switch out of the Tx phase
-when all the packets have been transmitted.
-
-Fix this by retaining the last-packet mark and only altering the packet
-state.

-When we terminate driver I/O (because we need to stop using a certain

-
-From: Sebastian Ott <sebott@linux.vnet.ibm.com>
-
-[ Upstream commit f97a6b6c47d2f329a24f92cc0ca3c6df5727ba73 ]
-
-There are cases a device driver can't start IO because the device is
-currently in use by cio. In this case the device driver is notified
-when the device is usable again.
-
-Using ccw_device_start_timeout we would set the timeout (and change
-an existing timeout) before we test for internal usage. Worst case
-this could lead to an unexpected timer deletion.
-
-Fix this by setting the timeout after we test for internal usage.

-Subject: s390/dasd: fix handling of internal requests
-
-From: Stefan Haberland <sth@linux.vnet.ibm.com>
-
-[ Upstream commit 9487cfd3430d07366801886bdf185799a2b6f066 ]
-
-Internal DASD device driver I/O such as query host access count or
-path verification is started using the _sleep_on() function.
-To mark a request as started or ended the callback_data is set to either
-DASD_SLEEPON_START_TAG or DASD_SLEEPON_END_TAG.
-
-In cases where the request has to be stopped unconditionally the status is
-set to DASD_SLEEPON_END_TAG as well which leads to immediate clearing of
-the request.
-But the request might still be on a device request queue for normal
-operation which might lead to a panic because of a BUG() statement in
-__dasd_device_process_final_queue() or a list corruption of the device
-request queue.
-
-Fix by removing the setting of DASD_SLEEPON_END_TAG in the
-dasd_cancel_req() and dasd_generic_requeue_all_requests() functions and
-ensure that the request is not deleted in the requeue function.
-Trigger the device tasklet in the requeue function and let the normal
-processing cleanup the request.

-
-We can get rid of it be the "traditional" means of adding an
-update_rq_clock() call after acquiring the rq->lock in
-do_sched_rt_period_timer().
-
-The case for the RT task throttling (which this workload also hits)
-can be ignored in that the skip_update call is actually bogus and
-quite the contrary (the request bits are removed/reverted).
-
-By setting RQCF_UPDATED we really don't care if the skip is happening
-or not and will therefore make the assert_clock_updated() check happy.

-Subject: scsi: aacraid: fix shutdown crash when init fails
-
-From: Meelis Roos <mroos@linux.ee>
-
-[ Upstream commit 00c20cdc79259c6c5bf978b21af96c2d3edb646d ]
-
-When aacraid init fails with "AAC0: adapter self-test failed.", shutdown
-leads to UBSAN warning and then oops:

-
-This is because aac_shutdown() does
-
- struct Scsi_Host *shost = pci_get_drvdata(dev);
- scsi_block_requests(shost);
-
-and that assumes shost has been assigned with pci_set_drvdata().
-
-However, pci_set_drvdata(pdev, shost) is done in aac_probe_one() far
-after bailing out with error from calling the init function
-((*aac_drivers[index].init)(aac)), and when the init function fails, no
-error is returned from aac_probe_one() so PCI layer assumes there is
-driver attached, and tries to shut it down later.
-
-Fix it by returning error from aac_probe_one() when card-specific init
-function fails.
-
-This fixes reboot on my HP NetRAID-4M with dead battery.

-
-From: Chad Dupuis <chad.dupuis@cavium.com>
-
-[ Upstream commit ecf7ff49945f5741fa1da112f994939f942031d3 ]
-
-When a request times out we set the io_req flag BNX2FC_FLAG_IO_COMPL so
-that if a subsequent completion comes in on that task ID we will ignore
-it. The issue is that in the check for this flag there is a missing
-return so we will continue to process a request which may have already
-been returned to the ownership of the SCSI layer. This can cause
-unpredictable results.
-
-Solution is to add in the missing return.

-Subject: scsi: core: Make SCSI Status CONDITION MET equivalent to GOOD
-
-From: Douglas Gilbert <dgilbert@interlog.com>
-
-[ Upstream commit 1875ede02ed5e176a18dccbca84abc28d5b3e141 ]
-
-The SCSI PRE-FETCH (10 or 16) command is present both on hard disks
-and some SSDs. It is useful when the address of the next block(s) to
-be read is known but it is not following the LBA of the current READ
-(so read-ahead won't help). It returns two "good" SCSI Status values.
-If the requested blocks have fitted (or will most likely fit (when
-the IMMED bit is set)) into the disk's cache, it returns CONDITION
-MET. If it didn't (or will not) fit then it returns GOOD status.
-
-The goal of this patch is to stop the SCSI subsystem treating the
-CONDITION MET SCSI status as an error. The current state makes the
-PRE-FETCH command effectively unusable via pass-throughs.

-From: Jason Yan <yanaijie@huawei.com>
-
-[ Upstream commit 318aaf34f1179b39fa9c30fa0f3288b645beee39 ]
-
-When ata device doing EH, some commands still attached with tasks are
-not passed to libata when abort failed or recover failed, so libata did
-not handle these commands. After these commands done, sas task is freed,
-but ata qc is not freed. This will cause ata qc leak and trigger a
-warning like below:

-
-If ata qc leaked too many, ata tag allocation will fail and io blocked
-for ever.
-
-As suggested by Dan Williams, defer ata device commands to libata and
-merge sas_eh_finish_cmd() with sas_eh_defer_cmd(). libata will handle
-ata qcs correctly after this.

-Subject: scsi: lpfc: Fix frequency of Release WQE CQEs
-
-From: James Smart <jsmart2021@gmail.com>
-
-[ Upstream commit 04673e38f56b30cd39b1fa0f386137d818b17781 ]
-
-The driver controls when the hardware sends completions that communicate
-consumption of elements from the WQ. This is done by setting a WQEC bit
-on a WQE.
-
-The current driver sets it on every Nth WQE posting. However, the driver
-isn't clearing the bit if the WQE is reused. Thus, if the queue depth
-isn't evenly divisible by N, with enough time, it can be set on every
-element, creating a lot of overhead and risking CQ full conditions.
-
-Correct by clearing the bit when not setting it on an Nth element.

-
-From: James Smart <jsmart2021@gmail.com>
-
-[ Upstream commit 161df4f09987ae2e9f0f97f0b38eee298b4a39ff ]
-
-During link bounce testing in a point-to-point topology, the host may
-enter a soft lockup on the lpfc_worker thread:
-
- Call Trace:
- lpfc_work_done+0x1f3/0x1390 [lpfc]
- lpfc_do_work+0x16f/0x180 [lpfc]
- kthread+0xc7/0xe0
- ret_from_fork+0x3f/0x70
-
-The driver was simultaneously setting a combination of flags that caused
-lpfc_do_work()to effectively spin between slow path work and new event
-data, causing the lockup.
-
-Ensure in the typical wq completions, that new event data flags are set
-if the slow path flag is running. The slow path will eventually
-reschedule the wq handling.

-cpu_msix_table is allocated to store online cpus, but pci_irq_get_affinity
-may return cpu_possible_mask which is then used to access cpu_msix_table.

-
-From: Andrew Vasquez <andrew.vasquez@cavium.com>
-
-[ Upstream commit 1683ce57f568c7c92d53e9234624a53554a29cd5 ]
-
-The data in NVRAM is not guaranteed to be NUL terminated. Since
-snprintf expects byte-stream to accommodate null byte, the CHAP secret
-is truncated. Use sprintf instead of snprintf to fix the truncation of
-CHAP name and secret.

-[ Upstream commit c02189e12ce3bf3808cb880569d3b10249f50bd9 ]

-A left shift must shift less than the bit width of the left argument.
-Avoid triggering undefined behavior if ha->mbx_count == 32.

-This patch avoids that UBSAN reports the following complaint:

-
-From: Jeremy Cline <jeremy@jcline.org>
-
-[ Upstream commit 20bd1d026aacc5399464f8328f305985c493cde3 ]
-
-If the read-only flag is true on a SCSI disk, re-reading the partition
-table sets the flag back to false.
-
-To observe this bug, you can run:
-
-1. blockdev --setro /dev/sda
-2. blockdev --rereadpt /dev/sda
-3. blockdev --getro /dev/sda
-
-This commit reads the disk's old state and combines it with the device
-disk-reported state rather than unconditionally marking it as RW.

-Subject: selftests/powerpc: Skip the subpage_prot tests if the syscall is unavailable
-
-From: Michael Ellerman <mpe@ellerman.id.au>
-
-[ Upstream commit cd4a6f3ab4d80cb919d15897eb3cbc85c2009d4b ]
-
-The subpage_prot syscall is only functional when the system is using
-the Hash MMU. Since commit 5b2b80714796 ("powerpc/mm: Invalidate
-subpage_prot() system call on radix platforms") it returns ENOENT when
-the Radix MMU is active. Currently this just makes the test fail.
-
-Additionally the syscall is not available if the kernel is built with
-4K pages, or if CONFIG_PPC_SUBPAGE_PROT=n, in which case it returns
-ENOSYS because the syscall is missing entirely.
-
-So check explicitly for ENOENT and ENOSYS and skip if we see either of
-those.

-Subject: selftests: Print the test we're running to /dev/kmsg
-
-From: Michael Ellerman <mpe@ellerman.id.au>
-
-[ Upstream commit 88893cf787d3062c631cc20b875068eb11756e03 ]
-
-Some tests cause the kernel to print things to the kernel log
-buffer (ie. printk), in particular oops and warnings etc. However when
-running all the tests in succession it's not always obvious which
-test(s) caused the kernel to print something.
-
-We can narrow it down by printing which test directory we're running
-in to /dev/kmsg, if it's writable.
-
-Example output:
-
- [ 170.149149] kselftest: Running tests in powerpc
- [ 305.300132] kworker/dying (71) used greatest stack depth: 7776 bytes

-Fix userfaultfd_hugetlb on hosts which have more than 64 cpus.
-
- ---------------------------
- running userfaultfd_hugetlb
- ---------------------------
- invalid MiB
- Usage: <MiB> <bounces>
- [FAIL]
-
-Via userfaultfd.c we can know, hugetlb_size needs to meet hugetlb_size
->= nr_cpus * hugepage_size. hugepage_size is often 2M, so when host
-cpus > 64, it requires more than 128M.

-Subject: serial: 8250: Don't service RX FIFO if interrupts are disabled
-
-From: Vignesh R <vigneshr@ti.com>
-
-[ Upstream commit 2e9fe539108320820016f78ca7704a7342788380 ]
-
-Currently, data in RX FIFO is read based on UART_LSR register state even
-if RDI and RLSI interrupts are disabled in UART_IER register.
-This is because when IRQ handler is called due to TX FIFO empty event,
-RX FIFO is serviced based on UART_LSR register status instead of
-UART_IIR status. This defeats the purpose of disabling UART RX
-FIFO interrupts during throttling(see, omap_8250_throttle()) as IRQ
-handler continues to drain UART RX FIFO resulting in overflow of buffer
-at tty layer.
-Fix this by making sure that driver drains UART RX FIFO only when
-UART_IIR_RDI is set along with UART_LSR_BI or UART_LSR_DR bits.

-The imx_ports[] array is indexed using a value derived from the
-"serialN" alias in DT, or from platform data, which may lead to an
-out-of-bounds access.

-
-From: Rich Felker <dalias@libc.org>
-
-[ Upstream commit 96a598996f6ac518ac79839ecbb17c91af91f4f7 ]
-
-When responding to a debug trap (breakpoint) in userspace, the
-kernel's trap handler raised SIGTRAP but returned from the trap via a
-code path that ignored pending signals, resulting in an infinite loop
-re-executing the trapping instruction.

-Subject: sh_eth: fix TSU init on SH7734/R8A7740
-
-From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>
-
-[ Upstream commit a94cf2a614f8bc5b2b33c708626ce695bf71e424 ]
-
-It appears that the single port Ether controllers having TSU (like SH7734/
-R8A7740) need the same kind of treating in sh_eth_tsu_init() as R7S72100
-currently has -- they also don't have the TSU registers related e.g. to
-passing the frames between ports. Add the 'sh_eth_cpu_data::dual_port'
-flag and use it as a new criterion for taking a "short path" in the TSU
-init sequence in order to avoid writing to the non-existent registers...

-Commit 128bb975dc3c ("ip6_gre: init dev->mtu and dev->hard_header_len

-mtu fix is also needed for sit.

-Note that dev->hard_header_len setting for sit works fine, no need to
-fix it. sit is actually ipv4 tunnel, it can't call ip6_tnl_change_mtu

-Subject: spectrum: Reference count VLAN entries
-
-From: Ido Schimmel <idosch@mellanox.com>
-
-[ Upstream commit b3529af6bb0d4fe72defdd539712ceffaa054fb3 ]
-
-One of the basic construct in the device is a port-VLAN pair, which can
-be bound to a FID or a RIF in order to direct packets to the bridge or
-the router, respectively.
-
-Since not all the netdevs are configured with a VLAN (e.g., sw1p1 vs.
-sw1p1.10), VID 1 is used to represent these and thus this VID can be
-used by both upper devices of mlxsw ports and by the driver itself.
-
-However, this VID is not reference counted and therefore might be freed
-prematurely, which can result in various WARNINGs. For example:
-
-$ ip link add name br0 type bridge vlan_filtering 1
-$ teamd -t team0 -d -c '{"runner": {"name": "lacp"}}'
-$ ip link set dev team0 master br0
-$ ip link set dev enp1s0np1 master team0
-$ ip address add 192.0.2.1/24 dev enp1s0np1
-
-The enslavement to team0 will fail because team0 already has an upper
-and thus vlan_vids_del_by_dev() will be executed as part of team's error
-path which will delete VID 1 from enp1s0np1 (added by br0 as PVID). The
-WARNING will be generated when the driver will realize it can't find VID
-1 on the port and bind it to a RIF.
-
-Fix this by adding a reference count to the VLAN entries on the port, in
-a similar fashion to the reference counting used by the corresponding
-'vlan_vid_info' structure in the 8021q driver.

-[ Upstream commit 626118b472d2eb45f83a0276a18d3e6a01c69f6a ]
-
-In the current implementation, `rmmod snd_bcm2835` does not release
-resources properly. It causes an oops when trying to list sound devices.
-
-This commit fixes it.
-
-The details WRT allocation / free are described below.
-
-Device structure WRT allocation:
-
-pdev
- \childdev[]
- \card
- \chip
- \pcm
- \ctl
-
-Allocation / register sequence:
-
-* childdev: devm_kzalloc - freed during driver detach
-* childdev: device_initialize - freed during device_unregister
-* pdev: devres_alloc - freed during driver detach
-* childdev: device_add - removed during device_unregister
-* pdev, childdev: devres_add - freed during driver detach
-* card: snd_card_new - freed during snd_card_free
-* chip: kzalloc - freed during kfree
-* card, chip: snd_device_new - freed during snd_device_free
-* chip: new_pcm - TODO: free pcm
-* chip: new_ctl - TODO: free ctl
-* card: snd_card_register - unregistered during snd_card_free
-
-Free / unregister sequence:
-
-* card: snd_card_free
-* card, chip: snd_device_free
-* childdev: device_unregister
-* chip: kfree
-
-Steps to reproduce the issue before this commit:

-
-[ Upstream commit 75c583ab9709692a60871d4719006391cde8dc1d ]
-
-The DPAA2 Ethernet driver incorrectly assumes virtual addresses
-are always 64b long, which causes compiler errors when building
-for a 32b platform.
-
-Fix this by using explicit casts to uintptr_t where necessary.

-Subject: staging: lustre: fix bug in osc_enter_cache_try
-
-From: NeilBrown <neilb@suse.com>
-
-[ Upstream commit 2fab9faf9b27298c4536c1c1b14072ab18b8f80b ]
-
-The lustre-release patch commit bdc5bb52c554 ("LU-4933 osc:
-Automatically increase the max_dirty_mb") changed
-
-- if (cli->cl_dirty + PAGE_CACHE_SIZE <= cli->cl_dirty_max &&
-+ if (cli->cl_dirty_pages < cli->cl_dirty_max_pages &&
-
-When this patch landed in Linux a couple of years later, it landed as
-
-- if (cli->cl_dirty + PAGE_SIZE <= cli->cl_dirty_max &&
-+ if (cli->cl_dirty_pages <= cli->cl_dirty_max_pages &&
-
-which is clearly different ('<=' vs '<'), and allows cl_dirty_pages to
-increase beyond cl_dirty_max_pages - which causes a latter assertion
-to fails.

-Subject: staging: lustre: lmv: correctly iput lmo_root
-
-From: NeilBrown <neilb@suse.com>
-
-[ Upstream commit 17556cdbe6ed70a6a20e597b228628f7f34387f8 ]
-
-Commit 8f18c8a48b73 ("staging: lustre: lmv: separate master object
-with master stripe") changed how lmo_root inodes were managed,
-particularly when LMV_HASH_FLAG_MIGRATION is not set.
-Previously lsm_md_oinfo[0].lmo_root was always a borrowed
-inode reference and didn't need to by iput().
-Since the change, that special case only applies when
-LMV_HASH_FLAG_MIGRATION is set
-
-In the upstream (lustre-release) version of this patch [Commit
-60e07b972114 ("LU-4690 lod: separate master object with master
-stripe")] the for loop in the lmv_unpack_md() was changed to count
-from 0 and to ignore entry 0 if LMV_HASH_FLAG_MIGRATION is set.
-In the patch that got applied to Linux, that change was missing,
-so lsm_md_oinfo[0].lmo_root is never iput().
-This results in a "VFS: Busy inodes" warning at unmount.

-Subject: swap: divide-by-zero when zero length swap file on ssd
-
-From: Tom Abraham <tabraham@suse.com>
-
-[ Upstream commit a06ad633a37c64a0cd4c229fc605cee8725d376e ]
-
-Calling swapon() on a zero length swap file on SSD can lead to a
-divide-by-zero.
-
-Although creating such files isn't possible with mkswap and they woud be
-considered invalid, it would be better for the swapon code to be more
-robust and handle this condition gracefully (return -EINVAL).
-Especially since the fix is small and straightforward.
-
-To help with wear leveling on SSD, the swapon syscall calculates a
-random position in the swap file using modulo p->highest_bit, which is
-set to maxpages - 1 in read_swap_header.
-
-If the swap file is zero length, read_swap_header sets maxpages=1 and
-last_page=0, resulting in p->highest_bit=0 and we divide-by-zero when we
-modulo p->highest_bit in swapon syscall.
-
-This can be prevented by having read_swap_header return zero if
-last_page is zero.

-Subject: tools/thermal: tmon: fix for segfault
-
-From: Frank Asseg <frank.asseg@objecthunter.net>
-
-[ Upstream commit 6c59f64b7ecf2bccbe73931d7d573d66ed13b537 ]
-
-Fixes a segfault occurring when e.g. <TAB> is pressed multiple times in the
-ncurses tmon application. The segfault is caused by incrementing
-cur_thermal_record in the main function without checking if it's value reached
-NR_THERMAL_RECORD immediately. Since the boundary check only occurred in
-update_thermal_data a race condition existed, which lead to an attempted read
-beyond the last element of the trec array.
-
-The fix was implemented by moving the cur_thermal_record incrementation to the
-update_thermal_data function using a temporary variable on which the boundary
-condition is checked before updating cur_thread_record, so that the variable is
-never incremented beyond the trec array's boundary.
-
-It seems the segfault does not occur on every machine: On a HP EliteBook G4 the
-segfault happens, while it does not happen on a Thinkpad T540p.

-
-From: Jan Kara <jack@suse.cz>

-
-Currently when UDF filesystem is recorded without uid / gid (ids are set
-to -1), we will assign INVALID_[UG]ID to vfs inode unless user uses uid=
-and gid= mount options. In such case filesystem could not be modified in
-any way as VFS refuses to modify files with invalid ids (even by root).
-This is confusing to users and not very useful default since such media
-mode is generally used for removable media. Use overflow[ug]id instead
-so that at least root can modify the filesystem.

-twice on usb anchor list.
-This patch also reset length of data before resue of a buffer.
-This not only prevent sending rubbish, but also lower risc of race.
-
-Without this patch we hit following kernel panic in one of our

-
-[ Upstream commit 755d739534f998d92e348fba8ffb0478416576e7 ]
-
-We should call dwc2_hsotg_enqueue_setup() after properly
-setting lx_state. Because it may cause error-out from
-dwc2_hsotg_enqueue_setup() due to wrong value in lx_state.
-
-Issue can be reproduced by loading driver while connected
-A-Connector (start in A-HOST mode) then disconnect A-Connector
-to switch to B-DEVICE.

-Subject: usb: gadget: composite: fix incorrect handling of OS desc requests
-
-From: Chris Dickens <christopher.a.dickens@gmail.com>
-
-[ Upstream commit 5d6ae4f0da8a64a185074dabb1b2f8c148efa741 ]
-
-When handling an OS descriptor request, one of the first operations is
-to zero out the request buffer using the wLength from the setup packet.
-There is no bounds checking, so a wLength > 4096 would clobber memory
-adjacent to the request buffer. Fix this by taking the min of wLength
-and the request buffer length prior to the memset. While at it, define
-the buffer length in a header file so that magic numbers don't appear
-throughout the code.
-
-When returning data to the host, the data length should be the min of
-the wLength and the valid data we have to return. Currently we are
-returning wLength, thus requests for a wLength greater than the amount
-of data in the OS descriptor buffer would return invalid (albeit zero'd)
-data following the valid descriptor data. Fix this by counting the
-number of bytes when constructing the data and using this when
-determining the length of the request.

-Subject: usb: gadget: ffs: Execute copy_to_user() with USER_DS set
-
-From: Lars-Peter Clausen <lars@metafoo.de>
-
-[ Upstream commit 4058ebf33cb0be88ca516f968eda24ab7b6b93e4 ]
-
-When using a AIO read() operation on the function FS gadget driver a URB is
-submitted asynchronously and on URB completion the received data is copied
-to the userspace buffer associated with the read operation.
-
-This is done from a kernel worker thread invoking copy_to_user() (through
-copy_to_iter()). And while the user space process memory is made available
-to the kernel thread using use_mm(), some architecture require in addition
-to this that the operation runs with USER_DS set. Otherwise the userspace
-memory access will fail.
-
-For example on ARM64 with Privileged Access Never (PAN) and User Access
-Override (UAO) enabled the following crash occurs.
-
- Internal error: Accessing user space memory with fs=KERNEL_DS: 9600004f [#1] SMP
- Modules linked in:
- CPU: 2 PID: 1636 Comm: kworker/2:1 Not tainted 4.9.0-04081-g8ab2dfb-dirty #487

-
-Address this by placing a set_fs(USER_DS) before of the copy operation
-and revert it again once the copy operation has finished.
-
-This patch is analogous to commit d7ffde35e31a ("vhost: use USER_DS in
-vhost_worker thread") which addresses the same underlying issue.

-Subject: usb: gadget: ffs: Let setup() return USB_GADGET_DELAYED_STATUS
-
-From: Lars-Peter Clausen <lars@metafoo.de>
-
-[ Upstream commit 946ef68ad4e45aa048a5fb41ce8823ed29da866a ]
-
-Some UDC drivers (like the DWC3) expect that the response to a setup()
-request is queued from within the setup function itself so that it is
-available as soon as setup() has completed.
-
-Upon receiving a setup request the function fs driver creates an event that
-is made available to userspace. And only once userspace has acknowledged
-that event the response to the setup request is queued.
-
-So it violates the requirement of those UDC drivers and random failures can
-be observed. This is basically a race condition and if userspace is able to
-read the event and queue the response fast enough all is good. But if it is
-not, for example because other processes are currently scheduled to run,
-the USB host that sent the setup request will observe an error.
-
-To avoid this the gadget framework provides the USB_GADGET_DELAYED_STATUS
-return code. If a setup() callback returns this value the UDC driver is
-aware that response is not yet available and can uses the appropriate
-methods to handle this case.
-
-Since in the case of function fs the response will never be available when
-the setup() function returns make sure that this status code is used.
-
-This fixed random occasional failures that were previously observed on a
-DWC3 based system under high system load.

-
-From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>
-
-[ Upstream commit d56e57ca030c8b4296944a2ae61ac167bf979c07 ]
-
-This patch reverts the commit 835e4241e714 ("usb: host: xhci-plat:
-enable clk in resume timing") because this driver also has runtime PM
-and the commit 560869100b99 ("clk: renesas: cpg-mssr: Restore module
-clocks during resume") will restore the clock on R-Car H3 environment.
-
-If the xhci_plat_suspend() disables the clk, the system cannot enable
-the clk in resume like the following behavior:
-
-< In resume >
- - genpd_resume_noirq() runs and enable the clk (enable_count = 1)
- - cpg_mssr_resume_noirq() restores the clk register.
- -- Since the clk was disabled in suspend, cpg_mssr_resume_noirq()
- will disable the clk and keep the enable_count.
- - Even if xhci_plat_resume() calls clk_prepare_enable(), since
- the enable_count is 1, the clk will be not enabled.
-
-After this patch is applied, the cpg-mssr driver will save the clk
-as enable, so the clk will be enabled in resume.

-
-Scatter-gather needs to be disabled when using dma_declare_coherent_memory
-and HCD_LOCAL_MEM. Andrea Righi made the equivalent fix for EHCI drivers
-in commit 4307a28eb01284 "USB: EHCI: fix NULL pointer dererence in HCDs
-that use HCD_LOCAL_MEM".
-
-The following NULL pointer WARN_ON_ONCE triggered with OHCI drivers:

-From: Kristian Evensen <kristian.evensen@gmail.com>
-
-[ Upstream commit 71a0483d56e784b1e11f38f10d7e22d265dbe244 ]
-
-The Quectel EP06 is a Cat. 6 LTE modem, and the interface mapping is as
-follows:
-
-0: Diag
-1: NMEA
-2: AT
-3: Modem
-
-Interface 4 is QMI and interface 5 is ADB, so they are blacklisted.
-
-This patch should also be considered for -stable. The QMI-patch for this
-modem is already in the -stable-queue.
-
-v1->v2:
-* Updated commit prefix (thanks Johan Hovold)
-* Updated commit message slightly.

-Subject: virtio-net: Fix operstate for virtio when no VIRTIO_NET_F_STATUS
-
-From: Jay Vosburgh <jay.vosburgh@canonical.com>
-
-[ Upstream commit bda7fab54828bbef2164bb23c0f6b1a7d05cc718 ]
-
-The operstate update logic will leave an interface in the
-default UNKNOWN operstate if the interface carrier state never changes
-from the default carrier up state set at creation. This includes the
-case of an explicit call to netif_carrier_on, as the carrier on to on
-transition has no effect on operstate.
-
- This affects virtio-net for the case that the virtio peer does
-not support VIRTIO_NET_F_STATUS (the feature that provides carrier state
-updates). Without this feature, the virtio specification states that
-"the link should be assumed active," so, logically, the operstate should
-be UP instead of UNKNOWN. This has impact on user space applications
-that use the operstate to make availability decisions for the interface.
-
- Resolve this by changing the virtio probe logic slightly to call
-netif_carrier_off for both the "with" and "without" VIRTIO_NET_F_STATUS
-cases, and then the existing call to netif_carrier_on for the "without"
-case will cause an operstate transition.

-Subject: virtio_net: fix XDP code path in receive_small()
-
-From: Jesper Dangaard Brouer <brouer@redhat.com>
-
-[ Upstream commit 95dbe9e7b3720efa5cf83d21f44f6d953f7cf4a2 ]
-
-When configuring virtio_net to use the code path 'receive_small()',
-in-order to get correct XDP_REDIRECT support, I discovered TCP packets
-would get silently dropped when loading an XDP program action XDP_PASS.
-
-The bug seems to be that receive_small() when XDP is loaded check that
-hdr->hdr.flags is zero, which seems wrong as hdr.flags contains the
-flags VIRTIO_NET_HDR_F_* :
- #define VIRTIO_NET_HDR_F_NEEDS_CSUM 1 /* Use csum_start, csum_offset */
- #define VIRTIO_NET_HDR_F_DATA_VALID 2 /* Csum is valid */
-
-TCP got dropped as it had the VIRTIO_NET_HDR_F_DATA_VALID flag set.
-
-The flags that are relevant here are the VIRTIO_NET_HDR_GSO_* flags
-stored in hdr->hdr.gso_type. Thus, the fix is just check that none of
-the gso_type flags have been set.

-Subject: vlan: Fix out of order vlan headers with reorder header off
-
-From: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp>
-
-[ Upstream commit cbe7128c4b92e2004984f477fd38dfa81662f02e ]
-
-With reorder header off, received packets are untagged in skb_vlan_untag()
-called from within __netif_receive_skb_core(), and later the tag will be
-inserted back in vlan_do_receive().
-
-This caused out of order vlan headers when we create a vlan device on top
-of another vlan device, because vlan_do_receive() inserts a tag as the
-outermost vlan tag. E.g. the outer tag is first removed in skb_vlan_untag()
-and inserted back in vlan_do_receive(), then the inner tag is next removed
-and inserted back as the outermost tag.
-
-This patch fixes the behaviour by inserting the inner tag at the right
-position.

-Subject: vlan: Fix vlan insertion for packets without ethernet header
-
-From: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp>
-
-[ Upstream commit c769accdf3d8a103940bea2979b65556718567e9 ]
-
-In some situation vlan packets do not have ethernet headers. One example
-is packets from tun devices. Users can specify vlan protocol in tun_pi
-field instead of IP protocol. When we have a vlan device with reorder_hdr
-disabled on top of the tun device, such packets from tun devices are
-untagged in skb_vlan_untag() and vlan headers will be inserted back in
-vlan_insert_inner_tag().
-
-vlan_insert_inner_tag() however did not expect packets without ethernet
-headers, so in such a case size argument for memmove() underflowed.
-
-We don't need to copy headers for packets which do not have preceding
-headers of vlan headers, so skip memmove() in that case.
-Also don't write vlan protocol in skb->data when it does not have enough
-room for it.

-Subject: vti4: Don't count header length twice on tunnel setup
-
-From: Stefano Brivio <sbrivio@redhat.com>
-
-[ Upstream commit dd1df24737727e119c263acf1be2a92763938297 ]
-
-This re-introduces the effect of commit a32452366b72 ("vti4:
-Don't count header length twice.") which was accidentally
-reverted by merge commit f895f0cfbb77 ("Merge branch 'master' of
-git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec").
-
-The commit message from Steffen Klassert said:
-
- We currently count the size of LL_MAX_HEADER and struct iphdr
- twice for vti4 devices, this leads to a wrong device mtu.
- The size of LL_MAX_HEADER and struct iphdr is already counted in
- ip_tunnel_bind_dev(), so don't do it again in vti_tunnel_init().
-
-And this is still the case now: ip_tunnel_bind_dev() already
-accounts for the header length of the link layer (not
-necessarily LL_MAX_HEADER, if the output device is found), plus
-one IP header.
-
-For example, with a vti device on top of veth, with MTU of 1500,
-the existing implementation would set the initial vti MTU to
-1332, accounting once for LL_MAX_HEADER (128, included in
-hard_header_len by vti) and twice for the same IP header (once
-from hard_header_len, once from ip_tunnel_bind_dev()).
-
-It should instead be 1480, because ip_tunnel_bind_dev() is able
-to figure out that the output device is veth, so no additional
-link layer header is attached, and will properly count one
-single IP header.
-
-The existing issue had the side effect of avoiding PMTUD for
-most xfrm policies, by arbitrarily lowering the initial MTU.
-However, the only way to get a consistent PMTU value is to let
-the xfrm PMTU discovery do its course, and commit d6af1a31cc72
-("vti: Add pmtu handling to vti_xmit.") now takes care of local
-delivery cases where the application ignores local socket
-notifications.
-
-Fixes: b9959fd3b0fa ("vti: switch to new ip tunnel code")

-From: Milton Miller <miltonm@us.ibm.com>
-
-[ Upstream commit 6ffa3402211acc30e47e691e14d62f3fd065a54e ]
-
-Allow the device tree to specify a watchdog to fallover to
-the alternate boot source.
-
-The aspeeed watchdog can set a latch directing flash chip select 0 to
-chip select 1, allowing boot from an alternate media if the watchdog
-is not reset in time. On the ast2400 bank 1 also goes to flash bank 1,
-while on the ast2500 the chip selects are swapped.
-
-Also clear the secondary boot bit during the machine restart operation.
-Otherwise, the system will switch to the alternate boot after every
-reboot, which is not desired.

-
-From: Brian Norris <briannorris@chromium.org>
-
-[ Upstream commit a81abbb412341e9e3b2d42ed7d310cf71fbb84a8 ]
-
-RK3399 has rst_pulse_length in CONTROL_REG[4:2], determining the length
-of pulse to issue for system reset. We shouldn't clobber this value,
-because that might make the system reset ineffective. On RK3399, we're
-seeing that a value of 000b (meaning 2 cycles) yields an unreliable
-(partial?) reset, and so we only fully reset after the watchdog fires a
-second time. If we retain the system default (010b, or 8 clock cycles),
-then the watchdog reset is much more reliable.
-
-Read-modify-write retains the system value and improves reset
-reliability.
-
-It seems we were intentionally clobbering the response mode previously,
-to ensure we performed a system reset (we don't support an interrupt
-notification), so retain that explicitly.

-
-From: Jayachandran C <jnair@caviumnetworks.com>
-
-[ Upstream commit 93ac3deb7c220cbcec032a967220a1f109d58431 ]
-
-According to SBSA spec v3.1 section 5.3:
- All registers are 32 bits in size and should be accessed using
- 32-bit reads and writes. If an access size other than 32 bits
- is used then the results are IMPLEMENTATION DEFINED.
- [...]
- The Generic Watchdog is little-endian
-
-The current code uses readq to read the watchdog compare register
-which does a 64-bit access. This fails on ThunderX2 which does not
-implement 64-bit access to this register.
-
-Fix this by using lo_hi_readq() that does two 32-bit reads.

-Subject: x86/apic: Set up through-local-APIC mode on the boot CPU if 'noapic' specified
-
-From: Baoquan He <bhe@redhat.com>
-
-[ Upstream commit bee3204ec3c49f6f53add9c3962c9012a5c036fa ]
-
-Currently the kdump kernel becomes very slow if 'noapic' is specified.
-Normal kernel doesn't have this bug.
-
-Kernel parameter 'noapic' is used to disable IO-APIC in system for
-testing or special purpose. Here the root cause is that in kdump
-kernel LAPIC is disabled since commit:
-
- 522e664644 ("x86/apic: Disable I/O APIC before shutdown of the local APIC")
-
-In this case we need set up through-local-APIC on boot CPU in
-setup_local_APIC().
-
-In normal kernel the legacy irq mode is enabled by the BIOS. If
-it is virtual wire mode, the local-APIC has been enabled and set as
-through-local-APIC.
-
-Though we fixed the regression introduced by commit 522e664644,
-to further improve robustness set up the through-local-APIC mode
-explicitly, do not rely on the default boot IRQ mode.

-
-From: Ivan Gorinov <ivan.gorinov@intel.com>
-
-[ Upstream commit 0a5169add90e43ab45ab1ba34223b8583fcaf675 ]
-
-IRQ parameters for the SoC devices connected directly to I/O APIC lines
-(without PCI IRQ routing) may be specified in the Device Tree.
-
-Called from DT IRQ parser, irq_create_fwspec_mapping() calls
-irq_domain_alloc_irqs() with a pointer to irq_fwspec structure as @arg.
-
-But x86-specific DT IRQ allocation code casts @arg to of_phandle_args
-structure pointer and crashes trying to read the IRQ parameters. The
-function was not converted when the mapping descriptor was changed to
-irq_fwspec in the generic irqdomain code.
-
-Fixes: 11e4438ee330 ("irqdomain: Introduce a firmware-specific IRQ specifier structure")

-
-From: Wang Hui <john.wanghui@huawei.com>
-
-[ Upstream commit 36e74d355297dde6e69a39c838d24710e442babe ]
-
-If no monitoring feature is detected because all monitoring features are
-disabled during boot time or there is no monitoring feature in hardware,
-creating rdtgroup sub-directory by "mkdir" command reports error:
-
- mkdir: cannot create directory ‘/sys/fs/resctrl/p1’: No such file or directory
-
-But the sub-directory actually is generated and content is correct:
-
- cpus cpus_list schemata tasks
-
-The error is because rdtgroup_mkdir_ctrl_mon() returns non zero value after
-the sub-directory is created and the returned value is reported as an error
-to user.
-
-Clear the returned value to report to user that the sub-directory is

-Subject: x86/mm: Do not forbid _PAGE_RW before init for __ro_after_init
-
-From: Dave Hansen <dave.hansen@linux.intel.com>
-
-[ Upstream commit 639d6aafe437a7464399d2a77d006049053df06f ]
-
-__ro_after_init data gets stuck in the .rodata section. That's normally
-fine because the kernel itself manages the R/W properties.
-
-But, if we run __change_page_attr() on an area which is __ro_after_init,
-the .rodata checks will trigger and force the area to be immediately
-read-only, even if it is early-ish in boot. This caused problems when
-trying to clear the _PAGE_GLOBAL bit for these area in the PTI code:
-it cleared _PAGE_GLOBAL like I asked, but also took it up on itself
-to clear _PAGE_RW. The kernel then oopses the next time it wrote to
-a __ro_after_init data structure.
-
-To fix this, add the kernel_set_to_readonly check, just like we have
-for kernel text, just a few lines below in this function.

-Subject: x86/mm: Fix bogus warning during EFI bootup, use boot_cpu_has() instead of this_cpu_has() in build_cr3_noflush()
-
-From: Sai Praneeth <sai.praneeth.prakhya@intel.com>
-
-[ Upstream commit 162ee5a8ab49be40d253f90e94aef712470a3a24 ]
-
-Linus reported the following boot warning:
-
- WARNING: CPU: 0 PID: 0 at arch/x86/include/asm/tlbflush.h:134 load_new_mm_cr3+0x114/0x170
- [...]
- Call Trace:
- switch_mm_irqs_off+0x267/0x590
- switch_mm+0xe/0x20
- efi_switch_mm+0x3e/0x50
- efi_enter_virtual_mode+0x43f/0x4da
- start_kernel+0x3bf/0x458
- secondary_startup_64+0xa5/0xb0
-
-... after merging:
-
- 03781e40890c: x86/efi: Use efi_switch_mm() rather than manually twiddling with %cr3
-
-When the platform supports PCID and if CONFIG_DEBUG_VM=y is enabled,
-build_cr3_noflush() (called via switch_mm()) does a sanity check to see
-if X86_FEATURE_PCID is set.
-
-Presently, build_cr3_noflush() uses "this_cpu_has(X86_FEATURE_PCID)" to
-perform the check but this_cpu_has() works only after SMP is initialized
-(i.e. per cpu cpu_info's should be populated) and this happens to be very
-late in the boot process (during rest_init()).
-
-As efi_runtime_services() are called during (early) kernel boot time
-and run time, modify build_cr3_noflush() to use boot_cpu_has() all the
-time. As suggested by Dave Hansen, this should be OK because all CPU's have
-same capabilities on x86.
-
-With this change the warning is fixed.
-
-( Dave also suggested that we put a warning in this_cpu_has() if it's used
- early in the boot process. This is still work in progress as it affects
- MCE. )

-Subject: x86/pgtable: Don't set huge PUD/PMD on non-leaf entries
-
-From: Joerg Roedel <joro@8bytes.org>
-
-[ Upstream commit e3e288121408c3abeed5af60b87b95c847143845 ]
-
-The pmd_set_huge() and pud_set_huge() functions are used from
-the generic ioremap() code to establish large mappings where this
-is possible.
-
-But the generic ioremap() code does not check whether the
-PMD/PUD entries are already populated with a non-leaf entry,
-so that any page-table pages these entries point to will be
-lost.
-
-Further, on x86-32 with SHARED_KERNEL_PMD=0, this causes a
-BUG_ON() in vmalloc_sync_one() when PMD entries are synced
-from swapper_pg_dir to the current page-table. This happens
-because the PMD entry from swapper_pg_dir was promoted to a
-huge-page entry while the current PGD still contains the
-non-leaf entry. Because both entries are present and point
-to a different page, the BUG_ON() triggers.
-
-This was actually triggered with pti-x32 enabled in a KVM
-virtual machine by the graphics driver.
-
-A real and better fix for that would be to improve the
-page-table handling in the generic ioremap() code. But that is
-out-of-scope for this patch-set and left for later work.

-Subject: x86/topology: Update the 'cpu cores' field in /proc/cpuinfo correctly across CPU hotplug operations
-
-From: Samuel Neves <sneves@dei.uc.pt>
-
-[ Upstream commit 4596749339e06dc7a424fc08a15eded850ed78b7 ]
-
-Without this fix, /proc/cpuinfo will display an incorrect amount
-of CPU cores, after bringing them offline and online again, as
-exemplified below:
-
- $ cat /proc/cpuinfo | grep cores
- cpu cores : 4
- cpu cores : 8
- cpu cores : 8
- cpu cores : 20
- cpu cores : 4
- cpu cores : 3
- cpu cores : 2
- cpu cores : 2
-
-This patch fixes this by always zeroing the booted_cores variable
-upon turning off a logical CPU.

-wrong. First of all there's an off-by-one in the cleanup loop, which
-can lead to unbinding wrong IRQs.
-
-Secondly IRQs not bound won't be freed, thus leaking IRQ numbers.

-Subject: xfrm: Fix ESN sequence number handling for IPsec GSO packets.
-
-From: Steffen Klassert <steffen.klassert@secunet.com>
-
-[ Upstream commit b8b549eec8187ac1b12075d69a2d84d89b5e811a ]
-
-When IPsec offloading was introduced, we accidentally incremented
-the sequence number counter on the xfrm_state by one packet
-too much in the ESN case. This leads to a sequence number gap of
-one packet after each GSO packet. Fix this by setting the sequence
-number to the correct value.

-
-[ Upstream commit 9a3fb9fb84cc30577c1b012a6a3efda944684291 ]
-
-A recent commit introduced a new struct xfrm_trans_cb
-that is used with the sk_buff control buffer. Unfortunately
-it placed the structure in front of the control buffer and
-overlooked that the IPv4/IPv6 control buffer is still needed
-for some layer 4 protocols. As a result the IPv4/IPv6 control
-buffer is overwritten with this structure. Fix this by setting
-a apropriate header in front of the structure.

-
-[ Upstream commit bde0716d1f076e4c913c7946bcc858f71243c7a0 ]
-
-For AMD Promontory xHCI host, although you can disable USB ports in
-BIOS settings, those ports will be enabled anyway after you remove a
-device on that port and re-plug it in again. It's a known limitation of
-the chip. As a workaround we can clear the PORT_WAKE_BITS.

-set udev->slot_id to zero when disabling and freeing the xhci slot.
-Prevents usb core from calling xhci with a stale slot id.
-
-xHC controller may be reset during resume to recover from some error.
-All slots are unusable as they are disabled and freed.
-xhci driver starts slot enumeration again from 1 in the order they are
-enabled. In the worst case a stale udev->slot_id for one device matches
-a newly enabled slot_id for a different device, causing us to
-perform a action on the wrong device.

-
-From: Michael Schmitz <schmitzmic@gmail.com>
-
-[ Upstream commit 55496d3fe2acd1a365c43cbd613a20ecd4d74395 ]
-
-The generic DMA API uses dev->dma_mask to check the DMA addressable
-memory bitmask, and warns if no mask is set or even allocated.
-
-Set z->dev.dma_coherent_mask on Zorro bus scan, and make z->dev.dma_mask
-to point to z->dev.dma_coherent_mask so device drivers that need DMA have
-everything set up to avoid warnings from dma_alloc_coherent(). Drivers can
-still use dma_set_mask_and_coherent() to explicitly set their DMA bit mask.
