+Subject: ACPI: APEI: fix return value of __setup handlers
+
+From: Randy Dunlap <rdunlap@infradead.org>
+
+[ Upstream commit f3303ff649dbf7dcdc6a6e1a922235b12b3028f4 ]
+
+__setup() handlers should return 1 to indicate that the boot option
+has been handled. Returning 0 causes a boot option to be listed in
+the Unknown kernel command line parameters and also added to init's
+arg list (if no '=' sign) or environment list (if of the form 'a=b').
+
+Unknown kernel command line parameters "erst_disable
+ bert_disable hest_disable BOOT_IMAGE=/boot/bzImage-517rc6", will be
+ passed to user space.
+
+ Run /sbin/init as init process
+ with arguments:
+ /sbin/init
+ erst_disable
+ bert_disable
+ hest_disable
+ with environment:
+ HOME=/
+ TERM=linux
+ BOOT_IMAGE=/boot/bzImage-517rc6

+Subject: ACPI/APEI: Limit printable size of BERT table data
+
+From: Darren Hart <darren@os.amperecomputing.com>
+
+[ Upstream commit 3f8dec116210ca649163574ed5f8df1e3b837d07 ]
+
+Platforms with large BERT table data can trigger soft lockup errors
+while attempting to print the entire BERT table data to the console at
+boot:
+
+ watchdog: BUG: soft lockup - CPU#160 stuck for 23s! [swapper/0:1]
+
+Observed on Ampere Altra systems with a single BERT record of ~250KB.
+
+The original bert driver appears to have assumed relatively small table
+data. Since it is impractical to reassemble large table data from
+interwoven console messages, and the table data is available in
+
+ /sys/firmware/acpi/tables/data/BERT
+
+limit the size for tables printed to the console to 1024 (for no reason
+other than it seemed like a good place to kick off the discussion, would
+appreciate feedback from existing users in terms of what size would
+maintain their current usage model).
+
+Alternatively, we could make printing a CONFIG option, use the
+bert_disable boot arg (or something similar), or use a debug log level.
+However, all those solutions require extra steps or change the existing
+behavior for small table data. Limiting the size preserves existing
+behavior on existing platforms with small table data, and eliminates the
+soft lockups for platforms with large table data, while still making it
+available.

+Subject: af_netlink: Fix shift out of bounds in group mask calculation
+
+From: Petr Machata <petrm@nvidia.com>
+
+[ Upstream commit 0caf6d9922192dd1afa8dc2131abfb4df1443b9f ]
+
+When a netlink message is received, netlink_recvmsg() fills in the address
+of the sender. One of the fields is the 32-bit bitfield nl_groups, which
+carries the multicast group on which the message was received. The least
+significant bit corresponds to group 1, and therefore the highest group
+that the field can represent is 32. Above that, the UB sanitizer flags the
+out-of-bounds shift attempts.
+
+Which bits end up being set in such case is implementation defined, but
+it's either going to be a wrong non-zero value, or zero, which is at least
+not misleading. Make the latter choice deterministic by always setting to 0
+for higher-numbered multicast groups.
+
+To get information about membership in groups >= 32, userspace is expected
+to use nl_pktinfo control messages[0], which are enabled by NETLINK_PKTINFO
+socket option.
+[0] https://lwn.net/Articles/147608/
+
+The way to trigger this issue is e.g. through monitoring the BRVLAN group:
+
+ # bridge monitor vlan &
+ # ip link add name br type bridge
+
+Which produces the following citation:
+
+ UBSAN: shift-out-of-bounds in net/netlink/af_netlink.c:162:19
+ shift exponent 32 is too large for 32-bit type 'int'

+Subject: ARM: ftrace: avoid redundant loads or clobbering IP
+
+From: Ard Biesheuvel <ardb@kernel.org>
+
+[ Upstream commit d11967870815b5ab89843980e35aab616c97c463 ]
+
+Tweak the ftrace return paths to avoid redundant loads of SP, as well as
+unnecessary clobbering of IP.
+
+This also fixes the inconsistency of using MOV to perform a function
+return, which is sub-optimal on recent micro-architectures but more
+importantly, does not perform an interworking return, unlike compiler
+generated function returns in Thumb2 builds.
+
+Let's fix this by popping PC from the stack like most ordinary code
+does.

+
+[ Upstream commit c953c764e505428f59ffe6afb1c73b89b5b1ac35 ]
+
+Broadcom ns2 platform has spi-cpol and spi-cpho properties set
+incorrectly. As per spi-slave-peripheral-prop.yaml, these properties are
+of flag or boolean type and not integer type. Fix the values.

+
+This function only calls of_node_put() in the regular path.
+And it will cause refcount leak in error paths.
+For example, when codec_np is NULL, saif_np[0] and saif_np[1]
+are not NULL, it will cause leaks.
+
+of_node_put() will check if the node pointer is NULL, so we can
+call it directly to release the refcount of regular pointers.

+In the case like dmaengine which's not a dai but as a component, the
+num_dai is zero, dmaengine component has the same component_of_node
+as cpu dai, when cpu dai component is not ready, but dmaengine component
+is ready, try to get cpu dai name, the snd_soc_get_dai_name() return
+-EINVAL, not -EPROBE_DEFER, that cause below error:
+
+asoc-simple-card <card name>: parse error -22
+asoc-simple-card: probe of <card name> failed with error -22
+
+The sound card failed to probe.
+
+So this patch fixes the issue above by skipping the zero num_dai
+component in searching dai name.

+Subject: ath10k: fix memory overwrite of the WoWLAN wakeup packet pattern
+
+From: Wen Gong <quic_wgong@quicinc.com>
+
+[ Upstream commit e3fb3d4418fce5484dfe7995fcd94c18b10a431a ]
+
+In function ath10k_wow_convert_8023_to_80211(), it will do memcpy for
+the new->pattern, and currently the new->pattern and new->mask is same
+with the old, then the memcpy of new->pattern will also overwrite the
+old->pattern, because the header format of new->pattern is 802.11,
+its length is larger than the old->pattern which is 802.3. Then the
+operation of "Copy frame body" will copy a mistake value because the
+body memory has been overwrite when memcpy the new->pattern.
+
+Assign another empty value to new_pattern to avoid the overwrite issue.
+
+Tested-on: QCA6174 hw3.2 SDIO WLAN.RMH.4.4.1-00049

+Subject: ath9k_htc: fix uninit value bugs
+
+From: Pavel Skripkin <paskripkin@gmail.com>
+
+[ Upstream commit d1e0df1c57bd30871dd1c855742a7c346dbca853 ]
+
+Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing
+field initialization.
+
+In htc_connect_service() svc_meta_len and pad are not initialized. Based
+on code it looks like in current skb there is no service data, so simply
+initialize svc_meta_len to 0.
+
+htc_issue_send() does not initialize htc_frame_hdr::control array. Based
+on firmware code, it will initialize it by itself, so simply zero whole
+array to make KMSAN happy
+
+Fail logs:

+In this function call, in_serv_queue has beed expired and meet the
+conditions to free. In the function bfq_dispatch_request, the address
+of in_serv_queue pointing to has been released. For getting the value
+of idle_timer_disabled, it will get flags value from the address which
+in_serv_queue pointing to, then the problem of use-after-free happens;
+
+Fix the problem by check in_serv_queue == bfqd->in_service_queue, to
+get the value of idle_timer_disabled if in_serve_queue is equel to
+bfqd->in_service_queue. If the space of in_serv_queue pointing has
+been released, this judge will aviod use-after-free problem.
+And if in_serv_queue may be expired or finished, the idle_timer_disabled
+will be false which would not give effects to bfq_update_dispatch_stats.

+Subject: Bluetooth: hci_serdev: call init_rwsem() before p->open()
+
+From: Pavel Skripkin <paskripkin@gmail.com>
+
+[ Upstream commit 9d7cbe2b9cf5f650067df4f402fdd799d4bbb4e1 ]
+
+kvartet reported, that hci_uart_tx_wakeup() uses uninitialized rwsem.
+The problem was in wrong place for percpu_init_rwsem() call.
+
+hci_uart_proto::open() may register a timer whose callback may call
+hci_uart_tx_wakeup(). There is a chance, that hci_uart_register_device()
+thread won't be fast enough to call percpu_init_rwsem().
+
+Fix it my moving percpu_init_rwsem() call before p->open().
+
+INFO: trying to register non-static key.
+The code is fine but needs lockdep annotation, or maybe
+you didn't initialize this object before use?
+turning off the locking correctness validator.

+
+In order that the end of a clk_div_table can be detected, it must be
+terminated with a sentinel element (.div = 0).
+
+In owl-s900.s, the { 0, 8 } element was probably meant to be just that,

+
+From: Dirk Buchwalder <buchwalder@posteo.de>
+
+[ Upstream commit b77d8306d84f83d1da68028a68c91da9c867b6f6 ]
+
+Use floor ops on SDCC1 APPS clock in order to round down selected clock
+frequency and avoid overclocking SD/eMMC cards.
+
+For example, currently HS200 cards were failling tuning as they were
+actually being clocked at 384MHz instead of 192MHz.
+This caused some boards to disable 1.8V I/O and force the eMMC into the
+standard HS mode (50MHz) and that appeared to work despite the eMMC being
+overclocked to 96Mhz in that case.
+
+There was a previous commit to use floor ops on SDCC clocks, but it looks
+to have only covered SDCC2 clock.

+Subject: clocksource: acpi_pm: fix return value of __setup handler
+
+From: Randy Dunlap <rdunlap@infradead.org>
+
+[ Upstream commit 6a861abceecb68497dd82a324fee45a5332dcece ]
+
+__setup() handlers should return 1 to obsolete_checksetup() in
+init/main.c to indicate that the boot option has been handled.
+A return of 0 causes the boot option/value to be listed as an Unknown
+kernel parameter and added to init's (limited) environment strings.
+
+The __setup() handler interface isn't meant to handle negative return
+values -- they are non-zero, so they mean "handled" (like a return
+value of 1 does), but that's just a quirk. So return 1 from
+parse_pmtmr(). Also print a warning message if kstrtouint() returns
+an error.

+From: Zhou Qingyang <zhou1615@umn.edu>
+
+[ Upstream commit 588a70177df3b1777484267584ef38ab2ca899a2 ]
+
+In amdgpu_dm_connector_add_common_modes(), amdgpu_dm_create_common_mode()
+is assigned to mode and is passed to drm_mode_probed_add() directly after
+that. drm_mode_probed_add() passes &mode->head to list_add_tail(), and
+there is a dereference of it in list_add_tail() without recoveries, which
+could lead to NULL pointer dereference on failure of
+amdgpu_dm_create_common_mode().
+
+Fix this by adding a NULL check of mode.
+
+This bug was found by a static analyzer.
+
+Builds with 'make allyesconfig' show no new warnings,
+and our static analyzer no longer warns about this code.

+Subject: drm/edid: Don't clear formats if using deep color
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Maxime Ripard <maxime@cerno.tech>
+
+[ Upstream commit 75478b3b393bcbdca4e6da76fe3a9f1a4133ec5d ]
+
+The current code, when parsing the EDID Deep Color depths, that the
+YUV422 cannot be used, referring to the HDMI 1.3 Specification.
+
+This specification, in its section 6.2.4, indeed states:
+
+ For each supported Deep Color mode, RGB 4:4:4 shall be supported and
+ optionally YCBCR 4:4:4 may be supported.
+
+ YCBCR 4:2:2 is not permitted for any Deep Color mode.
+
+This indeed can be interpreted like the code does, but the HDMI 1.4
+specification further clarifies that statement in its section 6.2.4:
+
+ For each supported Deep Color mode, RGB 4:4:4 shall be supported and
+ optionally YCBCR 4:4:4 may be supported.
+
+ YCBCR 4:2:2 is also 36-bit mode but does not require the further use
+ of the Deep Color modes described in section 6.5.2 and 6.5.3.
+
+This means that, even though YUV422 can be used with 12 bit per color,
+it shouldn't be treated as a deep color mode.
+
+This is also broken with YUV444 if it's supported by the display, but
+DRM_EDID_HDMI_DC_Y444 isn't set. In such a case, the code will clear
+color_formats of the YUV444 support set previously in
+drm_parse_cea_ext(), but will not set it back.
+
+Since the formats supported are already setup properly in
+drm_parse_cea_ext(), let's just remove the code modifying the formats in
+drm_parse_hdmi_deep_color_info()

+Subject: ext4: don't BUG if someone dirty pages without asking ext4 first
+
+From: Theodore Ts'o <tytso@mit.edu>
+
+[ Upstream commit cc5095747edfb054ca2068d01af20be3fcc3634f ]
+
+[un]pin_user_pages_remote is dirtying pages without properly warning
+the file system in advance. A related race was noted by Jan Kara in
+2018[1]; however, more recently instead of it being a very hard-to-hit
+race, it could be reliably triggered by process_vm_writev(2) which was
+discovered by Syzbot[2].
+
+This is technically a bug in mm/gup.c, but arguably ext4 is fragile in
+that if some other kernel subsystem dirty pages without properly
+notifying the file system using page_mkwrite(), ext4 will BUG, while
+other file systems will not BUG (although data will still be lost).
+
+So instead of crashing with a BUG, issue a warning (since there may be
+potential data loss) and just mark the page as clean to avoid
+unprivileged denial of service attacks until the problem can be
+properly fixed. More discussion and background can be found in the
+thread starting at [2].

+Subject: HID: i2c-hid: fix GET/SET_REPORT for unnumbered reports
+
+From: Dmitry Torokhov <dmitry.torokhov@gmail.com>
+
+[ Upstream commit a5e5e03e94764148a01757b2fa4737d3445c13a6 ]
+
+Internally kernel prepends all report buffers, for both numbered and
+unnumbered reports, with report ID, therefore to properly handle unnumbered
+reports we should prepend it ourselves.
+
+For the same reason we should skip the first byte of the buffer when
+calling i2c_hid_set_or_send_report() which then will take care of properly
+formatting the transfer buffer based on its separate report ID argument
+along with report payload.

+Add rate limiting to the message.

+
+If there is an input undervoltage fault, reported in STATUS_INPUT

+
+Add a constant for bit 3 of STATUS_INPUT. Update the Vin limit

+If an input undervoltage fault occurs, causing a unit off for

+If the watchdog was already enabled by the BIOS after booting, the

+
+This driver is for an FPGA logic core, so there can be arbitrarily many

+names were "xiic-i2c" which caused issues with lm_sensors when trying to
+map human-readable names to sensor inputs because it could not properly

+Subject: irqchip/qcom-pdc: Fix broken locking
+
+From: Marc Zyngier <maz@kernel.org>
+
+[ Upstream commit a6aca2f460e203781dc41391913cc5b54f4bc0ce ]
+
+pdc_enable_intr() serves as a primitive to qcom_pdc_gic_{en,dis}able,
+and has a raw spinlock for mutual exclusion, which is uses with
+interruptible primitives.
+
+This means that this critical section can itself be interrupted.
+Should the interrupt also be a PDC interrupt, and the endpoint driver
+perform an irq_disable() on that interrupt, we end-up in a deadlock.
+
+Fix this by using the irqsave/irqrestore variants of the locking
+primitives.

+From: Pavel Skripkin <paskripkin@gmail.com>
+
+[ Upstream commit 2cc7cc01c15f57d056318c33705647f87dcd4aab ]
+
+Syzbot reported divide error in dbNextAG(). The problem was in missing
+validation check for malicious image.
+
+Syzbot crafted an image with bmp->db_numag equal to 0. There wasn't any

+
+Fix it by validating bmp->db_numag in dbMount() and return an error if

+Subject: KVM: x86: Fix emulation in writing cr8
+
+From: Zhenzhong Duan <zhenzhong.duan@intel.com>
+
+[ Upstream commit f66af9f222f08d5b11ea41c1bd6c07a0f12daa07 ]
+
+In emulation of writing to cr8, one of the lowest four bits in TPR[3:0]
+is kept.
+
+According to Intel SDM 10.8.6.1(baremetal scenario):
+"APIC.TPR[bits 7:4] = CR8[bits 3:0], APIC.TPR[bits 3:0] = 0";
+
+and SDM 28.3(use TPR shadow):
+"MOV to CR8. The instruction stores bits 3:0 of its source operand into
+bits 7:4 of VTPR; the remainder of VTPR (bits 3:0 and bits 31:8) are
+cleared.";
+
+and AMD's APM 16.6.4:
+"Task Priority Sub-class (TPS)-Bits 3 : 0. The TPS field indicates the
+current sub-priority to be used when arbitrating lowest-priority messages.
+This field is written with zero when TPR is written using the architectural
+CR8 register.";
+
+so in KVM emulated scenario, clear TPR[3:0] to make a consistent behavior
+as in other scenarios.
+
+This doesn't impact evaluation and delivery of pending virtual interrupts
+because processor does not use the processor-priority sub-class to
+determine which interrupts to delivery and which to inhibit.
+
+Sub-class is used by hardware to arbitrate lowest priority interrupts,
+but KVM just does a round-robin style delivery.

+Subject: lib/raid6/test/Makefile: Use $(pound) instead of \# for Make 4.3
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Paul Menzel <pmenzel@molgen.mpg.de>
+
+[ Upstream commit 633174a7046ec3b4572bec24ef98e6ee89bce14b ]
+
+Buidling raid6test on Ubuntu 21.10 (ppc64le) with GNU Make 4.3 shows the
+errors below:
+
+ $ cd lib/raid6/test/
+ $ make
+ <stdin>:1:1: error: stray ‘\’ in program
+ <stdin>:1:2: error: stray ‘#’ in program
+ <stdin>:1:11: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ \
+ before ‘<’ token
+
+ [...]
+
+The errors come from the HAS_ALTIVEC test, which fails, and the POWER
+optimized versions are not built. That’s also reason nobody noticed on the
+other architectures.
+
+GNU Make 4.3 does not remove the backslash anymore. From the 4.3 release
+announcment:
+
+> * WARNING: Backward-incompatibility!
+> Number signs (#) appearing inside a macro reference or function invocation
+> no longer introduce comments and should not be escaped with backslashes:
+> thus a call such as:
+> foo := $(shell echo '#')
+> is legal. Previously the number sign needed to be escaped, for example:
+> foo := $(shell echo '\#')
+> Now this latter will resolve to "\#". If you want to write makefiles
+> portable to both versions, assign the number sign to a variable:
+> H := \#
+> foo := $(shell echo '$H')
+> This was claimed to be fixed in 3.81, but wasn't, for some reason.
+> To detect this change search for 'nocomment' in the .FEATURES variable.
+
+So, do the same as commit 9564a8cf422d ("Kbuild: fix # escaping in .cmd
+files for future Make") and commit 929bef467771 ("bpf: Use $(pound) instead
+of \# in Makefiles") and define and use a $(pound) variable.
+
+Reference for the change in make:
+https://git.savannah.gnu.org/cgit/make.git/commit/?id=c6966b323811c37acedff05b57

+
+[ Upstream commit c08eadca1bdfa099e20a32f8fa4b52b2f672236d ]
+
+The commit 47677e51e2a4("[media] em28xx: Only deallocate struct
+em28xx after finishing all extensions") adds kref_get to many init
+functions (e.g., em28xx_audio_init). However, kref_init is called too
+late in em28xx_usb_probe, since em28xx_init_dev before will invoke
+those init functions and call kref_get function. Then refcount bug
+occurs in my local syzkaller instance.
+
+Fix it by moving kref_init before em28xx_init_dev. This issue occurs
+not only in dev but also dev->dev_next.

+This reverts commit 2c98b8a3458df03abdc6945bbef67ef91d181938.
+
+Reverted patch causes problems with Hauppauge WinTV dualHD as Maximilian
+reported [1]. Since quick solution didn't come up let's just revert it
+to make this device work with upstream kernels.

+Subject: media: stk1160: If start stream fails, return buffers with
+ VB2_BUF_STATE_QUEUED
+
+From: Dafna Hirschfeld <dafna.hirschfeld@collabora.com>
+
+[ Upstream commit fbe04b49a54e31f4321d632270207f0e6304cd16 ]
+
+If the callback 'start_streaming' fails, then all
+queued buffers in the driver should be returned with
+state 'VB2_BUF_STATE_QUEUED'. Currently, they are
+returned with 'VB2_BUF_STATE_ERROR' which is wrong.
+Fix this. This also fixes the warning:

+Subject: MIPS: RB532: fix return value of __setup handler
+
+From: Randy Dunlap <rdunlap@infradead.org>
+
+[ Upstream commit 8755d57ba1ff910666572fab9e32890e8cc6ed3b ]
+
+__setup() handlers should return 1 to obsolete_checksetup() in
+init/main.c to indicate that the boot option has been handled.
+A return of 0 causes the boot option/value to be listed as an Unknown
+kernel parameter and added to init's (limited) argument or environment
+strings. Also, error return codes don't mean anything to
+obsolete_checksetup() -- only non-zero (usually 1) or zero.
+So return 1 from setup_kmac().

+Consider that platform_get_irq() can now in certain cases return

+
+The reference counting issue happens in several error handling paths
+on a refcounted object "nc->dmac". In these paths, the function simply
+returns the error code, forgetting to balance the reference count of

+
+Fix it by decrementing the refcount of specific object in those error
+paths.

+The assumption when these were relaxed seems to be that device memory
+would be mapped non reordering, and that other constructs
+(spinlocks/etc) would provide the barriers to assure that packet data
+and in memory rings/queues were ordered with respect to device
+register reads/writes. This itself seems a bit sketchy, but the real
+problem with GCC12 is that it is moving the actual reads/writes around
+at will as though they were independent operations when in truth they
+are not, but the compiler can't know that. When looking at the
+assembly dumps for many of these routines its possible to see very
+clean, but not strictly in program order operations occurring as the
+compiler would be free to do if these weren't actually register
+reads/write operations.
+
+Its possible to suppress the timeout with a liberal bit of dma_mb()'s
+sprinkled around but the device still seems unable to reliably
+send/receive data. A better plan is to use the safer readl/writel
+everywhere.
+
+Since this partially reverts an older commit, which notes the use of
+the relaxed variants for performance reasons. I would suggest that
+any performance problems with this commit are targeted at relaxing only
+the performance critical code paths after assuring proper barriers.

+
+From: Florian Fainelli <f.fainelli@gmail.com>
+
+[ Upstream commit bf8bfc4336f7a34e48b3bbd19b1542bf085bdc3d ]
+
+A Broadcom AC201 PHY (same entry as 5241) would be flagged by the
+Broadcom UniMAC MDIO controller as not completing the turn around
+properly since the PHY expects 65 MDC clock cycles to complete a write
+cycle, and the MDIO controller was only sending 64 MDC clock cycles as
+determined by looking at a scope shot.
+
+This would make the subsequent read fail with the UniMAC MDIO controller
+command field having MDIO_READ_FAIL set and we would abort the
+brcm_fet_config_init() function and thus not probe the PHY at all.
+
+After issuing a software reset, wait for at least 1ms which is well
+above the 1us reset delay advertised by the datasheet and issue a dummy
+read to let the PHY turn around the line properly. This read
+specifically ignores -EIO which would be returned by MDIO controllers
+checking for the line being turned around.
+
+If we have a genuine reaad failure, the next read of the interrupt
+status register would pick it up anyway.

+Subject: net/x25: Fix null-ptr-deref caused by x25_disconnect
+
+From: Duoming Zhou <duoming@zju.edu.cn>
+
+[ Upstream commit 7781607938c8371d4c2b243527430241c62e39c2 ]
+
+When the link layer is terminating, x25->neighbour will be set to NULL
+in x25_disconnect(). As a result, it could cause null-ptr-deref bugs in
+x25_sendmsg(),x25_recvmsg() and x25_connect(). One of the bugs is
+shown below.
+
+ (Thread 1) | (Thread 2)
+x25_link_terminated() | x25_recvmsg()
+ x25_kill_by_neigh() | ...
+ x25_disconnect() | lock_sock(sk)
+ ... | ...
+ x25->neighbour = NULL //(1) |
+ ... | x25->neighbour->extended //(2)
+
+The code sets NULL to x25->neighbour in position (1) and dereferences
+x25->neighbour in position (2), which could cause null-ptr-deref bug.
+
+This patch adds lock_sock() in x25_kill_by_neigh() in order to synchronize
+with x25_sendmsg(), x25_recvmsg() and x25_connect(). What`s more, the
+sock held by lock_sock() is not NULL, because it is extracted from x25_list
+and uses x25_list_lock to synchronize.

+
+[ Upstream commit 7c9d845f0612e5bcd23456a2ec43be8ac43458f1 ]
+
+In nfs4_callback_devicenotify(), if we don't find a matching entry for
+the deviceid, we're left with a pointer to 'struct nfs_server' that
+actually points to the list of super blocks associated with our struct
+nfs_client.
+Furthermore, even if we have a valid pointer, nothing pins the super
+block, and so the struct nfs_server could end up getting freed while
+we're using it.
+
+Since all we want is a pointer to the struct pnfs_layoutdriver_type,
+let's skip all the iteration over super blocks, and just use APIs to
+find the layout driver directly.

+Subject: ntfs: add sanity check on allocation size
+
+From: Dongliang Mu <mudongliangabcd@gmail.com>
+
+[ Upstream commit 714fbf2647b1a33d914edd695d4da92029c7e7c0 ]
+
+ntfs_read_inode_mount invokes ntfs_malloc_nofs with zero allocation
+size. It triggers one BUG in the __ntfs_malloc function.
+
+Fix this by adding sanity check on ni->attr_list_size.

+Subject: PCI: Reduce warnings on possible RW1C corruption
+
+From: Mark Tomlinson <mark.tomlinson@alliedtelesis.co.nz>
+
+[ Upstream commit 92c45b63ce22c8898aa41806e8d6692bcd577510 ]
+
+For hardware that only supports 32-bit writes to PCI there is the
+possibility of clearing RW1C (write-one-to-clear) bits. A rate-limited
+messages was introduced by fb2659230120, but rate-limiting is not the best
+choice here. Some devices may not show the warnings they should if another
+device has just produced a bunch of warnings. Also, the number of messages
+can be a nuisance on devices which are otherwise working fine.
+
+Change the ratelimit to a single warning per bus. This ensures no bus is
+'starved' of emitting a warning and also that there isn't a continuous
+stream of warnings. It would be preferable to have a warning per device,
+but the pci_dev structure is not available here, and a lookup from devfn
+would be far too slow.

+
+[ Upstream commit 524bb1da785a7ae43dd413cd392b5071c6c367f8 ]
+
+The function device_pm_check_callbacks() can be called under the spin
+lock (in the reported case it happens from genpd_add_device() ->
+dev_pm_domain_set(), when the genpd uses spinlocks rather than mutexes.
+

+spin_unlock_irq(), thus not preserving the CPU flags. Use the
+irqsave/irqrestore instead.

+From: Hans de Goede <hdegoede@redhat.com>
+
+[ Upstream commit f7731754fdce33dad19be746f647d6ac47c5d695 ]
+
+The datasheet says that the BQ24190_REG_POC_CHG_CONFIG bits can
+have a value of either 10(0x2) or 11(0x3) for OTG (5V boost regulator)
+mode.
+
+Sofar bq24190_vbus_is_enabled() was only checking for 10 but some BIOS-es
+uses 11 when enabling the regulator at boot.
+
+Make bq24190_vbus_is_enabled() also check for 11 so that it does not
+wrongly returns false when the bits are set to 11.

+Subject: powerpc/Makefile: Don't pass -mcpu=powerpc64 when building 32-bit
+
+From: Michael Ellerman <mpe@ellerman.id.au>
+
+[ Upstream commit 2863dd2db23e0407f6c50b8ba5c0e55abef894f1 ]
+
+When CONFIG_GENERIC_CPU=y (true for all our defconfigs) we pass
+-mcpu=powerpc64 to the compiler, even when we're building a 32-bit
+kernel.
+
+This happens because we have an ifdef CONFIG_PPC_BOOK3S_64/else block in
+the Makefile that was written before 32-bit supported GENERIC_CPU. Prior
+to that the else block only applied to 64-bit Book3E.
+
+The GCC man page says -mcpu=powerpc64 "[specifies] a pure ... 64-bit big
+endian PowerPC ... architecture machine [type], with an appropriate,
+generic processor model assumed for scheduling purposes."
+
+It's unclear how that interacts with -m32, which we are also passing,
+although obviously -m32 is taking precedence in some sense, as the
+32-bit kernel only contains 32-bit instructions.
+
+This was noticed by inspection, not via any bug reports, but it does
+affect code generation. Comparing before/after code generation, there
+are some changes to instruction scheduling, and the after case (with
+-mcpu=powerpc64 removed) the compiler seems more keen to use r8.
+
+Fix it by making the else case only apply to Book3E 64, which excludes
+32-bit.

+
+From: Randy Dunlap <rdunlap@infradead.org>
+
+[ Upstream commit b665eae7a788c5e2bc10f9ac3c0137aa0ad1fc97 ]
+
+If an invalid option value is used with "printk.devkmsg=<value>",
+it is silently ignored.
+If a valid option value is used, it is honored but the wrong return
+value (0) is used, indicating that the command line option had an
+error and was not handled. This string is not added to init's
+environment strings due to init/main.c::unknown_bootoption()
+checking for a '.' in the boot option string and then considering
+that string to be an "Unused module parameter".
+
+Print a warning message if a bad option string is used.
+Always return 1 from the __setup handler to indicate that the command
+line option has been handled.

+When a driver calls pwmchip_add() it has to be prepared to immediately

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Paolo Valente <paolo.valente@linaro.org>
+
+[ Upstream commit 15729ff8143f8135b03988a100a19e66d7cb7ecd ]
+
+A crash [1] happened to be triggered in conjunction with commit
+2d52c58b9c9b ("block, bfq: honor already-setup queue merges"). The
+latter was then reverted by commit ebc69e897e17 ("Revert "block, bfq:
+honor already-setup queue merges""). Yet, the reverted commit was not
+the one introducing the bug. In fact, it actually triggered a UAF
+introduced by a different commit, and now fixed by commit d29bd41428cf
+("block, bfq: reset last_bfqq_created on group change").
+
+So, there is no point in keeping commit 2d52c58b9c9b ("block, bfq:
+honor already-setup queue merges") out. This commit restores it.

+
+[ Upstream commit bb225b12dbcc82d53d637d10b8d70b64494f8c16 ]
+
+The fields of the set_ctrl_cfg_req structure have the __le32 type, so use
+cpu_to_le32() to assign them. This removes the sparse warnings:
+
+warning: incorrect type in assignment (different base types)
+ expected restricted __le32

+Subject: selftests/bpf/test_lirc_mode2.sh: Exit with proper code
+
+From: Hangbin Liu <liuhangbin@gmail.com>
+
+[ Upstream commit ec80906b0fbd7be11e3e960813b977b1ffe5f8fe ]
+
+When test_lirc_mode2_user exec failed, the test report failed but still
+exit with 0. Fix it by exiting with an error code.
+
+Another issue is for the LIRCDEV checking. With bash -n, we need to quote
+the variable, or it will always be true. So if test_lirc_mode2_user was
+not run, just exit with skip code.

+Add check to test if CC has a string. CC can have multiple sub-strings
+like "ccache gcc". Erorr pops up if it is treated as single string and
+double quotes are used around it. This can be fixed by removing the

+Subject: serial: 8250: Fix race condition in RTS-after-send handling
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
+
+[ Upstream commit dedab69fd650ea74710b2e626e63fd35584ef773 ]
+
+Set em485->active_timer = NULL isn't always enough to take out the stop
+timer. While there is a check that it acts in the right state (i.e.
+waiting for RTS-after-send to pass after sending some chars) but the
+following might happen:
+
+ - CPU1: some chars send, shifter becomes empty, stop tx timer armed
+ - CPU0: more chars send before RTS-after-send expired
+ - CPU0: shifter empty irq, port lock taken
+ - CPU1: tx timer triggers, waits for port lock
+ - CPU0: em485->active_timer = &em485->stop_tx_timer, hrtimer_start(),
+ releases lock()
+ - CPU1: get lock, see em485->active_timer == &em485->stop_tx_timer,
+ tear down RTS too early
+
+This fix bases on research done by Steffen Trumtrar.

+
+[ Upstream commit c3d66a164c726cc3b072232d3b6d87575d194084 ]
+
+platform_get_irq() returns negative error number instead 0 on failure.
+And the doc of platform_get_irq() provides a usage example:
+
+ int irq = platform_get_irq(pdev, 0);
+ if (irq < 0)
+ return irq;
+
+Fix the check of return value to catch errors correctly.

+Subject: tcp: ensure PMTU updates are processed during fastopen
+
+From: Jakub Kicinski <kuba@kernel.org>
+
+[ Upstream commit ed0c99dc0f499ff8b6e75b5ae6092ab42be1ad39 ]
+
+tp->rx_opt.mss_clamp is not populated, yet, during TFO send so we
+rise it to the local MSS. tp->mss_cache is not updated, however:
+
+tcp_v6_connect():
+ tp->rx_opt.mss_clamp = IPV6_MIN_MTU - headers;
+ tcp_connect():
+ tcp_connect_init():
+ tp->mss_cache = min(mtu, tp->rx_opt.mss_clamp)
+ tcp_send_syn_data():
+ tp->rx_opt.mss_clamp = tp->advmss
+
+After recent fixes to ICMPv6 PTB handling we started dropping
+PMTU updates higher than tp->mss_cache. Because of the stale
+tp->mss_cache value PMTU updates during TFO are always dropped.
+
+Thanks to Wei for helping zero in on the problem and the fix!

+Subject: TOMOYO: fix __setup handlers return values
+
+From: Randy Dunlap <rdunlap@infradead.org>
+
+[ Upstream commit 39844b7e3084baecef52d1498b5fa81afa2cefa9 ]
+
+__setup() handlers should return 1 if the parameter is handled.
+Returning 0 causes the entire string to be added to init's
+environment strings (limited to 32 strings), unnecessarily polluting it.
+
+Using the documented strings "TOMOYO_loader=string1" and
+"TOMOYO_trigger=string2" causes an Unknown parameter message:
+ Unknown kernel command line parameters
+ "BOOT_IMAGE=/boot/bzImage-517rc5 TOMOYO_loader=string1 \
+ TOMOYO_trigger=string2", will be passed to user space.
+
+and these strings are added to init's environment string space:
+ Run /sbin/init as init process
+ with arguments:
+ /sbin/init
+ with environment:
+ HOME=/
+ TERM=linux
+ BOOT_IMAGE=/boot/bzImage-517rc5
+ TOMOYO_loader=string1
+ TOMOYO_trigger=string2
+
+With this change, these __setup handlers act as expected,
+and init's environment is not polluted with these strings.

+Subject: tracing: Have TRACE_DEFINE_ENUM affect trace event types as well
+
+From: Steven Rostedt (Google) <rostedt@goodmis.org>
+
+[ Upstream commit b3bc8547d3be60898818885f5bf22d0a62e2eb48 ]
+
+The macro TRACE_DEFINE_ENUM is used to convert enums in the kernel to
+their actual value when they are exported to user space via the trace
+event format file.
+
+Currently only the enums in the "print fmt" (TP_printk in the TRACE_EVENT
+macro) have the enums converted. But the enums can be used to denote array
+size:
+
+ field:unsigned int fc_ineligible_rc[EXT4_FC_REASON_MAX]; offset:12; size:36; signed:0;
+
+The EXT4_FC_REASON_MAX has no meaning to userspace but it needs to know
+that information to know how to parse the array.
+
+Have the array indexes also be parsed as well.

+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+[ Upstream commit 78482af095abd9f4f29f1aa3fe575d25c6ae3028 ]
+
+This code has two bugs:
+1) "cnt" is 255 but the size of the buffer is 256 so the last byte is
+ not used.
+2) If we try to print more than 255 characters then "cnt" will be
+ negative and that will trigger a WARN() in snprintf(). The fix for
+ this is to use scnprintf() instead of snprintf().
+
+We can re-write this code to be cleaner:
+1) Rename "offset" to "off" because that's shorter.
+2) Get rid of the "cnt" variable and just use "size - off" directly.
+3) Get rid of the "read" variable and just increment "off" directly.

+
+From: Tim Gardner <tim.gardner@canonical.com>
+
+[ Upstream commit 37a1a2e6eeeb101285cd34e12e48a881524701aa ]
+
+Coverity complains of a possible buffer overflow. However,
+given the 'static' scope of nvidia_setup_i2c_bus() it looks
+like that can't happen after examiniing the call sites.
+
+CID 19036 (#1 of 1): Copy into fixed size buffer (STRING_OVERFLOW)
+1. fixed_size_dest: You might overrun the 48-character fixed-size string
+ chan->adapter.name by copying name without checking the length.
+2. parameter_as_source: Note: This defect has an elevated risk because the
+ source argument is a parameter of the current function.
+ 89 strcpy(chan->adapter.name, name);
+
+Fix this warning by using strscpy() which will silence the warning and
+prevent any future buffer overflows should the names used to identify the
+channel become much longer.

+
+From: Evgeny Novikov <novikov@ispras.ru>
+
+[ Upstream commit 8738ddcac644964ae128ccd3d80d48773c8d528e ]
+
+w100fb_probe() did not reset the global state to its initial state. This
+can result in invocation of iounmap() even when there was not the
+appropriate successful call of ioremap(). For instance, this may be the
+case if first probe fails after two successful ioremap() while second
+probe fails when first ioremap() fails. The similar issue is with
+w100fb_remove(). The patch fixes both bugs.
+
+Found by Linux Driver Verification project (linuxtesting.org).

+From: Randy Dunlap <rdunlap@infradead.org>
+
+[ Upstream commit bcfe9b6cbb4438b8c1cc4bd475221652c8f9301b ]
+
+Eliminate anonymous module_init() and module_exit(), which can lead to
+confusion or ambiguity when reading System.map, crashes/oops/bugs,
+or an initcall_debug log.
+
+Give each of these init and exit functions unique driver-specific
+names to eliminate the anonymous names.
+
+Example 1: (System.map)
+ ffffffff832fc78c t init
+ ffffffff832fc79e t init
+ ffffffff832fc8f8 t init
+
+Example 2: (initcall_debug log)
+ calling init+0x0/0x12 @ 1
+ initcall init+0x0/0x12 returned 0 after 15 usecs
+ calling init+0x0/0x60 @ 1
+ initcall init+0x0/0x60 returned 0 after 2 usecs
+ calling init+0x0/0x9a @ 1
+ initcall init+0x0/0x9a returned 0 after 74 usecs

+Subject: vxcan: enable local echo for sent CAN frames
+
+From: Oliver Hartkopp <socketcan@hartkopp.net>
+
+[ Upstream commit 259bdba27e32368b4404f69d613b1c1014c07cbf ]
+
+The vxcan driver provides a pair of virtual CAN interfaces to exchange
+CAN traffic between different namespaces - analogue to veth.
+
+In opposite to the vcan driver the local sent CAN traffic on this interface
+is not echo'ed back but only sent to the remote peer. This is unusual and
+can be easily fixed by removing IFF_ECHO from the netdevice flags that
+are set for vxcan interfaces by default at startup.
+
+Without IFF_ECHO set on driver level, the local sent CAN frames are echo'ed
+in af_can.c in can_send(). This patch makes vxcan interfaces adopt the
+same local echo behavior and procedures as known from the vcan interfaces.
+
+Fixes: a8f820a380a2 ("can: add Virtual CAN Tunnel driver (vxcan)")

+Subject: xen: fix is_xen_pmu()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Juergen Gross <jgross@suse.com>
+
+[ Upstream commit de2ae403b4c0e79a3410e63bc448542fbb9f9bfc ]
+
+is_xen_pmu() is taking the cpu number as parameter, but it is not using
+it. Instead it just tests whether the Xen PMU initialization on the
+current cpu did succeed. As this test is done by checking a percpu
+pointer, preemption needs to be disabled in order to avoid switching
+the cpu while doing the test. While resuming from suspend() this seems
+not to be the case:

+
+Fix that by replacing is_xen_pmu() by a simple boolean variable which
+reflects the Xen PMU initialization state on cpu 0.
+
+Modify xen_pmu_init() to return early in case it is being called for a
+cpu other than cpu 0 and the boolean variable not being set.
