+Subject: __legitimize_mnt(): check for MNT_SYNC_UMOUNT should be under
+ mount_lock
+
+From: Al Viro <viro@zeniv.linux.org.uk>
+
+[ Upstream commit 250cf3693060a5f803c5f1ddc082bb06b16112a9 ]
+
+... or we risk stealing final mntput from sync umount - raising mnt_count
+after umount(2) has verified that victim is not busy, but before it
+has set MNT_SYNC_UMOUNT; in that case __legitimize_mnt() doesn't see
+that it's safe to quietly undo mnt_count increment and leaves dropping
+the reference to caller, where it'll be a full-blown mntput().
+
+Check under mount_lock is needed; leaving the current one done before
+taking that makes no sense - it's nowhere near common enough to bother
+with.

+Subject: ACPI: HED: Always initialize before evged
+
+From: Xiaofei Tan <tanxiaofei@huawei.com>
+
+[ Upstream commit cccf6ee090c8c133072d5d5b52ae25f3bc907a16 ]
+
+When the HED driver is built-in, it initializes after evged because they
+both are at the same initcall level, so the initialization ordering
+depends on the Makefile order. However, this prevents RAS records
+coming in between the evged driver initialization and the HED driver
+initialization from being handled.
+
+If the number of such RAS records is above the APEI HEST error source
+number, the HEST resources may be exhausted, and that may affect
+subsequent RAS error reporting.
+
+To fix this issue, change the initcall level of HED to subsys_initcall
+and prevent the driver from being built as a module by changing ACPI_HED
+in Kconfig from "tristate" to "bool".

+Subject: ALSA: hda/realtek: Enable PC beep passthrough for HP EliteBook 855 G7
+
+From: Maciej S. Szmigiero <mail@maciej.szmigiero.name>
+
+[ Upstream commit aa85822c611aef7cd4dc17d27121d43e21bb82f0 ]
+
+PC speaker works well on this platform in BIOS and in Linux until sound
+card drivers are loaded. Then it stops working.
+
+There seems to be a beep generator node at 0x1a in this CODEC
+(ALC269_TYPE_ALC215) but it seems to be only connected to capture mixers
+at nodes 0x22 and 0x23.
+If I unmute the mixer input for 0x1a at node 0x23 and start recording
+from its "ALC285 Analog" capture device I can clearly hear beeps in that
+recording.
+
+So the beep generator is indeed working properly, however I wasn't able to
+figure out any way to connect it to speakers.
+
+However, the bits in the "Passthrough Control" register (0x36) seems to
+work at least partially: by zeroing "B" and "h" and setting "S" I can at
+least make the PIT PC speaker output appear either in this laptop speakers
+or headphones (depending on whether they are connected or not).
+
+There are some caveats, however:
+* If the CODEC gets runtime-suspended the beeps stop so it needs HDA beep
+device for keeping it awake during beeping.
+
+* If the beep generator node is generating any beep the PC beep passthrough
+seems to be temporarily inhibited, so the HDA beep device has to be
+prevented from using the actual beep generator node - but the beep device
+is still necessary due to the previous point.
+
+* In contrast with other platforms here beep amplification has to be
+disabled otherwise the beeps output are WAY louder than they were on pure
+BIOS setup.
+
+Unless someone (from Realtek probably) knows how to make the beep generator
+node output appear in speakers / headphones using PC beep passthrough seems
+to be the only way to make PC speaker beeping actually work on this
+platform.

+Subject: ALSA: seq: Improve data consistency at polling
+
+From: Takashi Iwai <tiwai@suse.de>
+
+[ Upstream commit e3cd33ab17c33bd8f1a9df66ec83a15dd8f7afbb ]
+
+snd_seq_poll() calls snd_seq_write_pool_allocated() that reads out a
+field in client->pool object, while it can be updated concurrently via
+ioctls, as reported by syzbot. The data race itself is harmless, as
+it's merely a poll() call, and the state is volatile. OTOH, the read
+out of poll object info from the caller side is fragile, and we can
+leave it better in snd_seq_pool_poll_wait() alone.
+
+A similar pattern is seen in snd_seq_kernel_client_write_poll(), too,
+which is called from the OSS sequencer.
+
+This patch drops the pool checks from the caller side and add the
+pool->lock in snd_seq_pool_poll_wait() for better data consistency.

+Subject: arch/powerpc/perf: Check the instruction type before creating sample
+ with perf_mem_data_src
+
+From: Athira Rajeev <atrajeev@linux.vnet.ibm.com>
+
+[ Upstream commit 2ffb26afa64261139e608bf087a0c1fe24d76d4d ]
+
+perf mem report aborts as below sometimes (during some corner
+case) in powerpc:
+
+ # ./perf mem report 1>out
+ *** stack smashing detected ***: terminated
+ Aborted (core dumped)
+
+The backtrace is as below:
+ __pthread_kill_implementation ()
+ raise ()
+ abort ()
+ __libc_message
+ __fortify_fail
+ __stack_chk_fail
+ hist_entry.lvl_snprintf
+ __sort__hpp_entry
+ __hist_entry__snprintf
+ hists.fprintf
+ cmd_report
+ cmd_mem
+
+Snippet of code which triggers the issue
+from tools/perf/util/sort.c
+
+ static int hist_entry__lvl_snprintf(struct hist_entry *he, char *bf,
+ size_t size, unsigned int width)
+ {
+ char out[64];
+
+ perf_mem__lvl_scnprintf(out, sizeof(out), he->mem_info);
+ return repsep_snprintf(bf, size, "%-*s", width, out);
+ }
+
+The value of "out" is filled from perf_mem_data_src value.
+Debugging this further showed that for some corner cases, the
+value of "data_src" was pointing to wrong value. This resulted
+in bigger size of string and causing stack check fail.
+
+The perf mem data source values are captured in the sample via
+isa207_get_mem_data_src function. The initial check is to fetch
+the type of sampled instruction. If the type of instruction is
+not valid (not a load/store instruction), the function returns.
+
+Since 'commit e16fd7f2cb1a ("perf: Use sample_flags for data_src")',
+data_src field is not initialized by the perf_sample_data_init()
+function. If the PMU driver doesn't set the data_src value to zero if
+type is not valid, this will result in uninitailised value for data_src.
+The uninitailised value of data_src resulted in stack check fail
+followed by abort for "perf mem report".
+
+When requesting for data source information in the sample, the
+instruction type is expected to be load or store instruction.
+In ISA v3.0, due to hardware limitation, there are corner cases
+where the instruction type other than load or store is observed.
+In ISA v3.0 and before values "0" and "7" are considered reserved.
+In ISA v3.1, value "7" has been used to indicate "larx/stcx".
+Drop the sample if instruction type has reserved values for this
+field with a ISA version check. Initialize data_src to zero in
+isa207_get_mem_data_src if the instruction type is not load/store.

+Subject: ARM: at91: pm: fix at91_suspend_finish for ZQ calibration
+
+From: Li Bin <bin.li@microchip.com>
+
+[ Upstream commit bc4722c3598d0e2c2dbf9609a3d3198993093e2b ]
+
+For sama7g5 and sama7d65 backup mode, we encountered a "ZQ calibrate error"
+during recalibrating the impedance in BootStrap.
+We found that the impedance value saved in at91_suspend_finish() before
+the DDR entered self-refresh mode did not match the resistor values. The
+ZDATA field in the DDR3PHY_ZQ0CR0 register uses a modified gray code to
+select the different impedance setting.
+But these gray code are incorrect, a workaournd from design team fixed the
+bug in the calibration logic. The ZDATA contains four independent impedance
+elements, but the algorithm combined the four elements into one. The elements
+were fixed using properly shifted offsets.

+Subject: arm64/mm: Check PUD_TYPE_TABLE in pud_bad()
+
+From: Ryan Roberts <ryan.roberts@arm.com>
+
+[ Upstream commit bfb1d2b9021c21891427acc86eb848ccedeb274e ]
+
+pud_bad() is currently defined in terms of pud_table(). Although for some
+configs, pud_table() is hard-coded to true i.e. when using 64K base pages
+or when page table levels are less than 3.
+
+pud_bad() is intended to check that the pud is configured correctly. Hence
+let's open-code the same check that the full version of pud_table() uses
+into pud_bad(). Then it always performs the check regardless of the config.

+Add support for GPIO headphone detection with the hp-det-gpios

+
+Describe a headphone jack and detection GPIO in the driver, check for

+Subject: ASoC: tas2764: Power up/down amp on mute ops
+
+From: Hector Martin <marcan@marcan.st>
+
+[ Upstream commit 1c3b5f37409682184669457a5bdf761268eafbe5 ]
+
+The ASoC convention is that clocks are removed after codec mute, and
+power up/down is more about top level power management. For these chips,
+the "mute" state still expects a TDM clock, and yanking the clock in
+this state will trigger clock errors. So, do the full
+shutdown<->mute<->active transition on the mute operation, so the amp is
+in software shutdown by the time the clocks are removed.
+
+This fixes TDM clock errors when streams are stopped.

+Subject: bonding: report duplicate MAC address in all situations
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Hangbin Liu <liuhangbin@gmail.com>
+
+[ Upstream commit 28d68d396a1cd21591e8c6d74afbde33a7ea107e ]
+
+Normally, a bond uses the MAC address of the first added slave as the bond’s
+MAC address. And the bond will set active slave’s MAC address to bond’s
+address if fail_over_mac is set to none (0) or follow (2).
+
+When the first slave is removed, the bond will still use the removed slave’s
+MAC address, which can lead to a duplicate MAC address and potentially cause
+issues with the switch. To avoid confusion, let's warn the user in all
+situations, including when fail_over_mac is set to 2 or not in active-backup
+mode.

+Subject: bpf: Prevent unsafe access to the sock fields in the BPF timestamping
+ callback
+
+From: Jason Xing <kerneljasonxing@gmail.com>
+
+[ Upstream commit fd93eaffb3f977b23bc0a48d4c8616e654fcf133 ]
+
+The subsequent patch will implement BPF TX timestamping. It will
+call the sockops BPF program without holding the sock lock.
+
+This breaks the current assumption that all sock ops programs will
+hold the sock lock. The sock's fields of the uapi's bpf_sock_ops
+requires this assumption.
+
+To address this, a new "u8 is_locked_tcp_sock;" field is added. This
+patch sets it in the current sock_ops callbacks. The "is_fullsock"
+test is then replaced by the "is_locked_tcp_sock" test during
+sock_ops_convert_ctx_access().
+
+The new TX timestamping callbacks added in the subsequent patch will
+not have this set. This will prevent unsafe access from the new
+timestamping callbacks.
+
+Potentially, we could allow read-only access. However, this would
+require identifying which callback is read-safe-only and also requires
+additional BPF instruction rewrites in the covert_ctx. Since the BPF
+program can always read everything from a socket (e.g., by using
+bpf_core_cast), this patch keeps it simple and disables all read
+and write access to any socket fields through the bpf_sock_ops
+UAPI from the new TX timestamping callback.
+
+Moreover, note that some of the fields in bpf_sock_ops are specific
+to tcp_sock, and sock_ops currently only supports tcp_sock. In
+the future, UDP timestamping will be added, which will also break
+this assumption. The same idea used in this patch will be reused.
+Considering that the current sock_ops only supports tcp_sock, the
+variable is named is_locked_"tcp"_sock.

+The `readlink(path, buf, sizeof(buf))` call reads at most sizeof(buf)

+
+From: Mark Harmstone <maharmstone@fb.com>
+
+[ Upstream commit 7ef3cbf17d2734ca66c4ed8573be45f4e461e7ee ]
+
+The inline function btrfs_is_testing() is hardcoded to return 0 if
+CONFIG_BTRFS_FS_RUN_SANITY_TESTS is not set. Currently we're relying on
+the compiler optimizing out the call to alloc_test_extent_buffer() in
+btrfs_find_create_tree_block(), as it's not been defined (it's behind an
+ #ifdef).
+
+Add a stub version of alloc_test_extent_buffer() to avoid linker errors
+on non-standard optimization levels. This problem was seen on GCC 14
+with -O0 and is helps to see symbols that would be otherwise optimized
+out.

+
+From: Goldwyn Rodrigues <rgoldwyn@suse.de>
+
+[ Upstream commit bc7e0975093567f51be8e1bdf4aa5900a3cf0b1e ]
+
+btrfs_prelim_ref() calls the old and new reference variables in the

+is passed as NULL to trace_btrfs_prelim_ref_insert().

+Note, trace_btrfs_prelim_ref_insert() is being called with newref as
+oldref (and oldref as NULL) on purpose in order to print out
+the values of newref.

+Subject: btrfs: fix non-empty delayed iputs list on unmount due to async
+ workers
+
+From: Filipe Manana <fdmanana@suse.com>
+
+[ Upstream commit cda76788f8b0f7de3171100e3164ec1ce702292e ]
+
+At close_ctree() after we have ran delayed iputs either explicitly through
+calling btrfs_run_delayed_iputs() or later during the call to
+btrfs_commit_super() or btrfs_error_commit_super(), we assert that the
+delayed iputs list is empty.
+
+We have (another) race where this assertion might fail because we have
+queued an async write into the fs_info->workers workqueue. Here's how it
+happens:
+
+1) We are submitting a data bio for an inode that is not the data
+ relocation inode, so we call btrfs_wq_submit_bio();
+
+2) btrfs_wq_submit_bio() submits a work for the fs_info->workers queue
+ that will run run_one_async_done();
+
+3) We enter close_ctree(), flush several work queues except
+ fs_info->workers, explicitly run delayed iputs with a call to
+ btrfs_run_delayed_iputs() and then again shortly after by calling
+ btrfs_commit_super() or btrfs_error_commit_super(), which also run
+ delayed iputs;
+
+4) run_one_async_done() is executed in the work queue, and because there
+ was an IO error (bio->bi_status is not 0) it calls btrfs_bio_end_io(),
+ which drops the final reference on the associated ordered extent by
+ calling btrfs_put_ordered_extent() - and that adds a delayed iput for
+ the inode;
+
+5) At close_ctree() we find that after stopping the cleaner and
+ transaction kthreads the delayed iputs list is not empty, failing the
+ following assertion:
+
+ ASSERT(list_empty(&fs_info->delayed_iputs));
+
+Fix this by flushing the fs_info->workers workqueue before running delayed
+iputs at close_ctree().
+
+David reported this when running generic/648, which exercises IO error
+paths by using the DM error table.

+Subject: btrfs: make btrfs_discard_workfn() block_group ref explicit
+
+From: Boris Burkov <boris@bur.io>
+
+[ Upstream commit 895c6721d310c036dcfebb5ab845822229fa35eb ]
+
+Currently, the async discard machinery owns a ref to the block_group
+when the block_group is queued on a discard list. However, to handle
+races with discard cancellation and the discard workfn, we have a
+specific logic to detect that the block_group is *currently* running in
+the workfn, to protect the workfn's usage amidst cancellation.
+
+As far as I can tell, this doesn't have any overt bugs (though
+finish_discard_pass() and remove_from_discard_list() racing can have a
+surprising outcome for the caller of remove_from_discard_list() in that
+it is again added at the end).
+
+But it is needlessly complicated to rely on locking and the nullity of
+discard_ctl->block_group. Simplify this significantly by just taking a
+refcount while we are in the workfn and unconditionally drop it in both
+the remove and workfn paths, regardless of if they race.

+Subject: btrfs: run btrfs_error_commit_super() early
+
+From: Qu Wenruo <wqu@suse.com>
+
+[ Upstream commit df94a342efb451deb0e32b495d1d6cd4bb3a1648 ]
+
+[BUG]
+Even after all the error fixes related the
+"ASSERT(list_empty(&fs_info->delayed_iputs));" in close_ctree(), I can
+still hit it reliably with my experimental 2K block size.
+
+[CAUSE]
+In my case, all the error is triggered after the fs is already in error
+status.
+
+I find the following call trace to be the cause of race:
+
+ Main thread | endio_write_workers
+---------------------------------------------+---------------------------
+close_ctree() |
+|- btrfs_error_commit_super() |
+| |- btrfs_cleanup_transaction() |
+| | |- btrfs_destroy_all_ordered_extents() |
+| | |- btrfs_wait_ordered_roots() |
+| |- btrfs_run_delayed_iputs() |
+| | btrfs_finish_ordered_io()
+| | |- btrfs_put_ordered_extent()
+| | |- btrfs_add_delayed_iput()
+|- ASSERT(list_empty(delayed_iputs)) |
+ !!! Triggered !!!
+
+The root cause is that, btrfs_wait_ordered_roots() only wait for
+ordered extents to finish their IOs, not to wait for them to finish and
+removed.
+
+[FIX]
+Since btrfs_error_commit_super() will flush and wait for all ordered
+extents, it should be executed early, before we start flushing the
+workqueues.
+
+And since btrfs_error_commit_super() now runs early, there is no need to
+run btrfs_run_delayed_iputs() inside it, so just remove the
+btrfs_run_delayed_iputs() call from btrfs_error_commit_super().

+From: Filipe Manana <fdmanana@suse.com>
+
+[ Upstream commit a77749b3e21813566cea050bbb3414ae74562eba ]
+
+When attempting to build a too long path we are currently returning
+-ENOMEM, which is very odd and misleading. So update fs_path_ensure_buf()
+to return -ENAMETOOLONG instead. Also, while at it, move the WARN_ON()
+into the if statement's expression, as it makes it clear what is being
+tested and also has the effect of adding 'unlikely' to the statement,
+which allows the compiler to generate better code as this condition is
+never expected to happen.

+
+[ Upstream commit 87c259a7a359e73e6c52c68fcbec79988999b4e6 ]
+
+When adding folio_memcg function call in the zram module for
+Android16-6.12, the following error occurs during compilation:
+ERROR: modpost: "cgroup_mutex" [../soc-repo/zram.ko] undefined!
+
+This error is caused by the indirect call to lockdep_is_held(&cgroup_mutex)
+within folio_memcg. The export setting for cgroup_mutex is controlled by
+the CONFIG_PROVE_RCU macro. If CONFIG_LOCKDEP is enabled while
+CONFIG_PROVE_RCU is not, this compilation error will occur.
+
+To resolve this issue, add a parallel macro CONFIG_LOCKDEP control to
+ensure cgroup_mutex is properly exported when needed.

+
+From: Pali Rohár <pali@kernel.org>

+[ Upstream commit e255612b5ed9f179abe8196df7c2ba09dd227900 ]
+
+Some operations, like WRITE, does not require FILE_READ_ATTRIBUTES access.
+
+So when FILE_READ_ATTRIBUTES is not explicitly requested for
+smb2_open_file() then first try to do SMB2 CREATE with FILE_READ_ATTRIBUTES
+access (like it was before) and then fallback to SMB2 CREATE without
+FILE_READ_ATTRIBUTES access (less common case).
+
+This change allows to complete WRITE operation to a file when it does not
+grant FILE_READ_ATTRIBUTES permission and its parent directory does not
+grant READ_DATA permission (parent directory READ_DATA is implicit grant of
+child FILE_READ_ATTRIBUTES permission).

+Subject: cifs: Fix establishing NetBIOS session for SMB2+ connection
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Pali Rohár <pali@kernel.org>
+
+[ Upstream commit 781802aa5a5950f99899f13ff9d760f5db81d36d ]
+
+Function ip_rfc1001_connect() which establish NetBIOS session for SMB
+connections, currently uses smb_send() function for sending NetBIOS Session
+Request packet. This function expects that the passed buffer is SMB packet
+and for SMB2+ connections it mangles packet header, which breaks prepared
+NetBIOS Session Request packet. Result is that this function send garbage
+packet for SMB2+ connection, which SMB2+ server cannot parse. That function
+is not mangling packets for SMB1 connections, so it somehow works for SMB1.
+
+Fix this problem and instead of smb_send(), use smb_send_kvec() function
+which does not mangle prepared packet, this function send them as is. Just
+API of this function takes struct msghdr (kvec) instead of packet buffer.
+
+[MS-SMB2] specification allows SMB2 protocol to use NetBIOS as a transport
+protocol. NetBIOS can be used over TCP via port 139. So this is a valid
+configuration, just not so common. And even recent Windows versions (e.g.
+Windows Server 2022) still supports this configuration: SMB over TCP port
+139, including for modern SMB2 and SMB3 dialects.
+
+This change fixes SMB2 and SMB3 connections over TCP port 139 which
+requires establishing of NetBIOS session. Tested that this change fixes
+establishing of SMB2 and SMB3 connections with Windows Server 2022.

+Subject: cifs: Fix negotiate retry functionality
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Pali Rohár <pali@kernel.org>
+
+[ Upstream commit e94e882a6d69525c07589222cf3a6ff57ad12b5b ]
+
+SMB negotiate retry functionality in cifs_negotiate() is currently broken
+and does not work when doing socket reconnect. Caller of this function,
+which is cifs_negotiate_protocol() requires that tcpStatus after successful
+execution of negotiate callback stay in CifsInNegotiate. But if the
+CIFSSMBNegotiate() called from cifs_negotiate() fails due to connection
+issues then tcpStatus is changed as so repeated CIFSSMBNegotiate() call
+does not help.
+
+Fix this problem by moving retrying code from negotiate callback (which is
+either cifs_negotiate() or smb2_negotiate()) to cifs_negotiate_protocol()
+which is caller of those callbacks. This allows to properly handle and
+implement correct transistions between tcpStatus states as function
+cifs_negotiate_protocol() already handles it.
+
+With this change, cifs_negotiate_protocol() now handles also -EAGAIN error
+set by the RFC1002_NEGATIVE_SESSION_RESPONSE processing after reconnecting
+with NetBIOS session.

+Subject: cifs: Fix querying and creating MF symlinks over SMB1
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Pali Rohár <pali@kernel.org>
+
+[ Upstream commit 4236ac9fe5b8b42756070d4abfb76fed718e87c2 ]
+
+Old SMB1 servers without CAP_NT_SMBS do not support CIFS_open() function
+and instead SMBLegacyOpen() needs to be used. This logic is already handled
+in cifs_open_file() function, which is server->ops->open callback function.
+
+So for querying and creating MF symlinks use open callback function instead
+of CIFS_open() function directly.
+
+This change fixes querying and creating new MF symlinks on Windows 98.
+Currently cifs_query_mf_symlink() is not able to detect MF symlink and
+cifs_create_mf_symlink() is failing with EIO error.

+Subject: clk: imx8mp: inform CCF of maximum frequency of clocks
+
+From: Ahmad Fatoum <a.fatoum@pengutronix.de>
+
+[ Upstream commit 06a61b5cb6a8638fa8823cd09b17233b29696fa2 ]
+
+The IMX8MPCEC datasheet lists maximum frequencies allowed for different
+modules. Some of these limits are universal, but some depend on
+whether the SoC is operating in nominal or in overdrive mode.
+
+The imx8mp.dtsi currently assumes overdrive mode and configures some
+clocks in accordance with this. Boards wishing to make use of nominal
+mode will need to override some of the clock rates manually.
+
+As operating the clocks outside of their allowed range can lead to
+difficult to debug issues, it makes sense to register the maximum rates
+allowed in the driver, so the CCF can take them into account.

+From: Jordan Crouse <jorcrous@amazon.com>
+
+[ Upstream commit 52b10b591f83dc6d9a1d6c2dc89433470a787ecd ]
+
+Update some RCGs on the sm8250 camera clock controller to use
+clk_rcg2_shared_ops. The shared_ops ensure the RCGs get parked
+to the XO during clock disable to prevent the clocks from locking up
+when the GDSC is enabled. These mirror similar fixes for other controllers
+such as commit e5c359f70e4b ("clk: qcom: camcc: Update the clock ops for
+the SC7180").

+Subject: clk: qcom: clk-alpha-pll: Do not use random stack value for recalc
+ rate
+
+From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
+
+[ Upstream commit 7a243e1b814a02ab40793026ef64223155d86395 ]
+
+If regmap_read() fails, random stack value was used in calculating new
+frequency in recalc_rate() callbacks. Such failure is really not
+expected as these are all MMIO reads, however code should be here
+correct and bail out. This also avoids possible warning on
+uninitialized value.

+Subject: clocksource: mips-gic-timer: Enable counter when CPUs start
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Paul Burton <paulburton@kernel.org>
+
+[ Upstream commit 3128b0a2e0cf6e07aa78e5f8cf7dd9cd59dc8174 ]
+
+In multi-cluster MIPS I6500 systems there is a GIC in each cluster,
+each with its own counter. When a cluster powers up the counter will
+be stopped, with the COUNTSTOP bit set in the GIC_CONFIG register.
+
+In single cluster systems, it has been fine to clear COUNTSTOP once
+in gic_clocksource_of_init() to start the counter. In multi-cluster
+systems, this will only have started the counter in the boot cluster,
+and any CPUs in other clusters will find their counter stopped which
+will break the GIC clock_event_device.
+
+Resolve this by having CPUs clear the COUNTSTOP bit when they come
+online, using the existing gic_starting_cpu() CPU hotplug callback. This
+will allow CPUs in secondary clusters to ensure that the cluster's GIC
+counter is running as expected.

+Subject: cpuidle: menu: Avoid discarding useful information
+
+From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+
+[ Upstream commit 85975daeaa4d6ec560bfcd354fc9c08ad7f38888 ]
+
+When giving up on making a high-confidence prediction,
+get_typical_interval() always returns UINT_MAX which means that the
+next idle interval prediction will be based entirely on the time till
+the next timer. However, the information represented by the most
+recent intervals may not be completely useless in those cases.
+
+Namely, the largest recent idle interval is an upper bound on the
+recently observed idle duration, so it is reasonable to assume that
+the next idle duration is unlikely to exceed it. Moreover, this is
+still true after eliminating the suspected outliers if the sample
+set still under consideration is at least as large as 50% of the
+maximum sample set size.
+
+Accordingly, make get_typical_interval() return the current maximum
+recent interval value in that case instead of UINT_MAX.

+Subject: crypto: lzo - Fix compression buffer overrun
+
+From: Herbert Xu <herbert@gondor.apana.org.au>
+
+[ Upstream commit cc47f07234f72cbd8e2c973cdbf2a6730660a463 ]
+
+Unlike the decompression code, the compression code in LZO never
+checked for output overruns. It instead assumes that the caller
+always provides enough buffer space, disregarding the buffer length
+provided by the caller.
+
+Add a safe compression interface that checks for the end of buffer
+before each write. Use the safe interface in crypto/lzo.

+Subject: dm cache: prevent BUG_ON by blocking retries on failed device resumes
+
+From: Ming-Hung Tsai <mtsai@redhat.com>
+
+[ Upstream commit 5da692e2262b8f81993baa9592f57d12c2703dea ]
+
+A cache device failing to resume due to mapping errors should not be
+retried, as the failure leaves a partially initialized policy object.
+Repeating the resume operation risks triggering BUG_ON when reloading
+cache mappings into the incomplete policy object.
+
+Reproduce steps:
+
+1. create a cache metadata consisting of 512 or more cache blocks,
+ with some mappings stored in the first array block of the mapping
+ array. Here we use cache_restore v1.0 to build the metadata.
+
+cat <<EOF >> cmeta.xml
+<superblock uuid="" block_size="128" nr_cache_blocks="512" \
+policy="smq" hint_width="4">
+ <mappings>
+ <mapping cache_block="0" origin_block="0" dirty="false"/>
+ </mappings>
+</superblock>
+EOF
+dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
+cache_restore -i cmeta.xml -o /dev/mapper/cmeta --metadata-version=2
+dmsetup remove cmeta
+
+2. wipe the second array block of the mapping array to simulate
+ data degradations.
+
+mapping_root=$(dd if=/dev/sdc bs=1c count=8 skip=192 \
+2>/dev/null | hexdump -e '1/8 "%u\n"')
+ablock=$(dd if=/dev/sdc bs=1c count=8 skip=$((4096*mapping_root+2056)) \
+2>/dev/null | hexdump -e '1/8 "%u\n"')
+dd if=/dev/zero of=/dev/sdc bs=4k count=1 seek=$ablock
+
+3. try bringing up the cache device. The resume is expected to fail
+ due to the broken array block.
+
+dmsetup create cmeta --table "0 8192 linear /dev/sdc 0"
+dmsetup create cdata --table "0 65536 linear /dev/sdc 8192"
+dmsetup create corig --table "0 524288 linear /dev/sdc 262144"
+dmsetup create cache --notable
+dmsetup load cache --table "0 524288 cache /dev/mapper/cmeta \
+/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writethrough smq 0"
+dmsetup resume cache
+
+4. try resuming the cache again. An unexpected BUG_ON is triggered
+ while loading cache mappings.
+
+dmsetup resume cache

+Subject: dm: fix unconditional IO throttle caused by REQ_PREFLUSH
+
+From: Jinliang Zheng <alexjlzheng@gmail.com>
+
+[ Upstream commit 88f7f56d16f568f19e1a695af34a7f4a6ce537a6 ]
+
+When a bio with REQ_PREFLUSH is submitted to dm, __send_empty_flush()
+generates a flush_bio with REQ_OP_WRITE | REQ_PREFLUSH | REQ_SYNC,
+which causes the flush_bio to be throttled by wbt_wait().
+
+An example from v5.4, similar problem also exists in upstream:
+

+
+After commit 2def2845cc33 ("xfs: don't allow log IO to be throttled"),
+the metadata submitted by xlog_write_iclog() should not be throttled.
+But due to the existence of the dm layer, throttling flush_bio indirectly
+causes the metadata bio to be throttled.
+
+Fix this by conditionally adding REQ_IDLE to flush_bio.bi_opf, which makes
+wbt_should_throttle() return false to avoid wbt_wait().

+Subject: dql: Fix dql->limit value when reset.
+
+From: Jing Su <jingsusu@didiglobal.com>
+
+[ Upstream commit 3a17f23f7c36bac3a3584aaf97d3e3e0b2790396 ]
+
+Executing dql_reset after setting a non-zero value for limit_min can
+lead to an unreasonable situation where dql->limit is less than
+dql->limit_min.
+
+For instance, after setting
+/sys/class/net/eth*/queues/tx-0/byte_queue_limits/limit_min,
+an ifconfig down/up operation might cause the ethernet driver to call
+netdev_tx_reset_queue, which in turn invokes dql_reset.
+
+In this case, dql->limit is reset to 0 while dql->limit_min remains
+non-zero value, which is unexpected. The limit should always be
+greater than or equal to limit_min.

+
+From: Zhikai Zhai <zhikai.zhai@amd.com>
+
+[ Upstream commit d3069feecdb5542604d29b59acfd1fd213bad95b ]
+
+[WHY]
+In some cases the remain de-tile buffer segments will be greater
+than zero if we don't add the non-top pipe to calculate, at
+this time the override de-tile buffer size will be valid and used.
+But it makes the de-tile buffer segments used finally for all of pipes
+exceed the maximum.
+
+[HOW]
+Add the non-top pipe to calculate the remain de-tile buffer segments.
+Don't set override size to use the average according to pipe count
+if the value exceed the maximum.

+Subject: drm/amd/display: Guard against setting dispclk low for dcn31x
+
+From: Jing Zhou <Jing.Zhou@amd.com>
+
+[ Upstream commit 9c2f4ae64bb6f6d83a54d88b9ee0f369cdbb9fa8 ]
+
+[WHY]
+We should never apply a minimum dispclk value while in
+prepare_bandwidth or while displays are active. This is
+always an optimizaiton for when all displays are disabled.
+
+[HOW]
+Defer dispclk optimization until safe_to_lower = true
+and display_count reaches 0.
+
+Since 0 has a special value in this logic (ie. no dispclk
+required) we also need adjust the logic that clamps it for
+the actual request to PMFW.

+Subject: drm/ast: Find VBIOS mode from regular display size
+
+From: Thomas Zimmermann <tzimmermann@suse.de>
+
+[ Upstream commit c81202906b5cd56db403e95db3d29c9dfc8c74c1 ]
+
+The ast driver looks up supplied display modes from an internal list of
+display modes supported by the VBIOS.
+
+Do not use the crtc_-prefixed display values from struct drm_display_mode
+for looking up the VBIOS mode. The fields contain raw values that the
+driver programs to hardware. They are affected by display settings like
+double-scan or interlace.
+
+Instead use the regular vdisplay and hdisplay fields for lookup. As the
+programmed values can now differ from the values used for lookup, set
+struct drm_display_mode.crtc_vdisplay and .crtc_hdisplay from the VBIOS
+mode.

+
+msm is automagically upgrading normal commits to full modesets, and
+that's a big no-no:
+
+- for one this results in full on->off->on transitions on all these
+ crtc, at least if you're using the usual helpers. Which seems to be
+ the case, and is breaking uapi
+
+- further even if the ctm change itself would not result in flicker,
+ this can hide modesets for other reasons. Which again breaks the
+ uapi
+
+v2: I forgot the case of adding unrelated crtc state. Add that case
+and link to the existing kerneldoc explainers. This has come up in an
+irc discussion with Manasi and Ville about intel's bigjoiner mode.
+Also cc everyone involved in the msm irc discussion, more people

+
+In preparation for adding support for newer DPI instances which

+Subject: drm/panel-edp: Add Starry 116KHD024006
+
+From: Douglas Anderson <dianders@chromium.org>
+
+[ Upstream commit 749b5b279e5636cdcef51e15d67b77162cca6caa ]
+
+We have a few reports of sc7180-trogdor-pompom devices that have a
+panel in them that IDs as STA 0x0004 and has the following raw EDID:
+
+ 00 ff ff ff ff ff ff 00 4e 81 04 00 00 00 00 00
+ 10 20 01 04 a5 1a 0e 78 0a dc dd 96 5b 5b 91 28
+ 1f 52 54 00 00 00 01 01 01 01 01 01 01 01 01 01
+ 01 01 01 01 01 01 8e 1c 56 a0 50 00 1e 30 28 20
+ 55 00 00 90 10 00 00 18 00 00 00 00 00 00 00 00
+ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
+ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 fe
+ 00 31 31 36 4b 48 44 30 32 34 30 30 36 0a 00 e6
+
+We've been unable to locate a datasheet for this panel and our partner
+has not been responsive, but all Starry eDP datasheets that we can
+find agree on the same timing (delay_100_500_e200) so it should be
+safe to use that here instead of the super conservative timings. We'll
+still go a little extra conservative and allow `hpd_absent` of 200
+instead of 100 because that won't add any real-world delay in most
+cases.
+
+We'll associate the string from the EDID ("116KHD024006") with this
+panel. Given that the ID is the suspicious value of 0x0004 it seems
+likely that Starry doesn't always update their IDs but the string will
+still work to differentiate if we ever need to in the future.

+
+From: Andy Yan <andy.yan@rock-chips.com>
+
+[ Upstream commit e7aae9f6d762139f8d2b86db03793ae0ab3dd802 ]
+
+The Cluster windows of upcoming VOP on rk3576 also support
+linear YUV support, we need to set uv swap bit for it.
+
+As the VOP2_WIN_UV_SWA register defined on rk3568/rk3588 is
+0xffffffff, so this register will not be touched on these
+two platforms.

+From: Arnd Bergmann <arnd@arndb.de>
+
+[ Upstream commit c29dfd661fe2f8d1b48c7f00590929c04b25bf40 ]

+
+drivers/edac/ie31200_edac.c: In function 'ie31200_probe1.isra':
+drivers/edac/ie31200_edac.c:412:26: error: 'dimm_info' is used uninitialized [-Werror=uninitialized]

+ | ^~~~~~~~~
+
+I don't see any way the unintialized access could really happen here,
+but I can see why the compiler gets confused by the two loops.
+
+Instead, rework the two nested loops to only read the addr_decode
+registers and then keep only one instance of the dimm info structure.
+
+[Tony: Qiuxu pointed out that the "populate DIMM info" comment was left
+behind in the refactor and suggested moving it. I deleted the comment
+as unnecessry in front os a call to populate_dimm_info(). That seems
+pretty self-describing.]

+Subject: exit: fix the usage of delay_group_leader->exit_code in
+ do_notify_parent() and pidfs_exit()
+
+From: Oleg Nesterov <oleg@redhat.com>
+
+[ Upstream commit 9133607de37a4887c6f89ed937176a0a0c1ebb17 ]
+
+Consider a process with a group leader L and a sub-thread T.
+L does sys_exit(1), then T does sys_exit_group(2).
+
+In this case wait_task_zombie(L) will notice SIGNAL_GROUP_EXIT and use
+L->signal->group_exit_code, this is correct.
+
+But, before that, do_notify_parent(L) called by release_task(T) will use
+L->exit_code != L->signal->group_exit_code, and this is not consistent.
+We don't really care, I think that nobody relies on the info which comes
+with SIGCHLD, if nothing else SIGCHLD < SIGRTMIN can be queued only once.
+
+But pidfs_exit() is more problematic, I think pidfs_exit_info->exit_code
+should report ->group_exit_code in this case, just like wait_task_zombie().
+
+TODO: with this change we can hopefully cleanup (or may be even kill) the
+similar SIGNAL_GROUP_EXIT checks, at least in wait_task_zombie().

+
+capable() calls refer to enabled LSMs whether to permit or deny the

+capability check results in a policy decision and by default a denial
+message on insufficient permission is issued.
+It can lead to three undesired cases:
+ 1. A denial message is generated, even in case the operation was an
+ unprivileged one and thus the syscall succeeded, creating noise.
+ 2. To avoid the noise from 1. the policy writer adds a rule to ignore
+ those denial messages, hiding future syscalls, where the task
+ performs an actual privileged operation, leading to hidden limited
+ functionality of that task.
+ 3. To avoid the noise from 1. the policy writer adds a rule to permit
+ the task the requested capability, while it does not need it,
+ violating the principle of least privilege.

+Subject: fbcon: Use correct erase colour for clearing in fbcon
+
+From: Zsolt Kajtar <soci@c64.rulez.org>
+
+[ Upstream commit 892c788d73fe4a94337ed092cb998c49fa8ecaf4 ]
+
+The erase colour calculation for fbcon clearing should use get_color instead
+of attr_col_ec, like everything else. The latter is similar but is not correct.
+For example it's missing the depth dependent remapping and doesn't care about
+blanking.
+
+The problem can be reproduced by setting up the background colour to grey
+(vt.color=0x70) and having an fbcon console set to 2bpp (4 shades of gray).
+Now the background attribute should be 1 (dark gray) on the console.
+
+If the screen is scrolled when pressing enter in a shell prompt at the bottom
+line then the new line is cleared using colour 7 instead of 1. That's not
+something fillrect likes (at 2bbp it expect 0-3) so the result is interesting.
+
+This patch switches to get_color with vc_video_erase_char to determine the
+erase colour from attr_col_ec. That makes the latter function redundant as
+no other users were left.
+

+Subject: fbdev: core: tileblit: Implement missing margin clearing for tileblit
+
+From: Zsolt Kajtar <soci@c64.rulez.org>
+
+[ Upstream commit 76d3ca89981354e1f85a3e0ad9ac4217d351cc72 ]
+
+I was wondering why there's garbage at the bottom of the screen when
+tile blitting is used with an odd mode like 1080, 600 or 200. Sure there's
+only space for half a tile but the same area is clean when the buffer
+is bitmap.
+
+Then later I found that it's supposed to be cleaned but that's not
+implemented. So I took what's in bitblit and adapted it for tileblit.
+
+This implementation was tested for both the horizontal and vertical case,
+and now does the same as what's done for bitmap buffers.
+
+If anyone is interested to reproduce the problem then I could bet that'd
+be on a S3 or Ark. Just set up a mode with an odd line count and make
+sure that the virtual size covers the complete tile at the bottom. E.g.
+for 600 lines that's 608 virtual lines for a 16 tall tile. Then the
+bottom area should be cleaned.
+
+For the right side it's more difficult as there the drivers won't let an
+odd size happen, unless the code is modified. But once it reports back a
+few pixel columns short then fbcon won't use the last column. With the
+patch that column is now clean.
+
+Btw. the virtual size should be rounded up by the driver for both axes
+(not only the horizontal) so that it's dividable by the tile size.
+That's a driver bug but correcting it is not in scope for this patch.
+

+
+From: Kuhanh Murugasen Krishnan <kuhanh.murugasen.krishnan@intel.com>
+
+[ Upstream commit 0f05886a40fdc55016ba4d9ae0a9c41f8312f15b ]
+
+Increase the timeout for SDM (Secure device manager) data credits from
+20ms to 40ms. Internal stress tests running at 500 loops failed with the
+current timeout of 20ms. At the start of a FPGA configuration, the CVP
+host driver reads the transmit credits from SDM. It then sends bitstream
+FPGA data to SDM based on the total credits. Each credit allows the
+CVP host driver to send 4kBytes of data. There are situations whereby,
+the SDM did not respond in time during testing.

+Subject: genirq/msi: Store the IOMMU IOVA directly in msi_desc instead of
+ iommu_cookie
+
+From: Jason Gunthorpe <jgg@nvidia.com>
+
+[ Upstream commit 1f7df3a691740a7736bbc99dc4ed536120eb4746 ]
+
+The IOMMU translation for MSI message addresses has been a 2-step process,
+separated in time:
+
+ 1) iommu_dma_prepare_msi(): A cookie pointer containing the IOVA address
+ is stored in the MSI descriptor when an MSI interrupt is allocated.
+
+ 2) iommu_dma_compose_msi_msg(): this cookie pointer is used to compute a
+ translated message address.
+
+This has an inherent lifetime problem for the pointer stored in the cookie
+that must remain valid between the two steps. However, there is no locking
+at the irq layer that helps protect the lifetime. Today, this works under
+the assumption that the iommu domain is not changed while MSI interrupts
+being programmed. This is true for normal DMA API users within the kernel,
+as the iommu domain is attached before the driver is probed and cannot be
+changed while a driver is attached.
+
+Classic VFIO type1 also prevented changing the iommu domain while VFIO was
+running as it does not support changing the "container" after starting up.
+
+However, iommufd has improved this so that the iommu domain can be changed
+during VFIO operation. This potentially allows userspace to directly race
+VFIO_DEVICE_ATTACH_IOMMUFD_PT (which calls iommu_attach_group()) and
+VFIO_DEVICE_SET_IRQS (which calls into iommu_dma_compose_msi_msg()).
+
+This potentially causes both the cookie pointer and the unlocked call to
+iommu_get_domain_for_dev() on the MSI translation path to become UAFs.
+
+Fix the MSI cookie UAF by removing the cookie pointer. The translated IOVA
+address is already known during iommu_dma_prepare_msi() and cannot change.
+Thus, it can simply be stored as an integer in the MSI descriptor.
+
+The other UAF related to iommu_get_domain_for_dev() will be addressed in
+patch "iommu: Make iommu_dma_prepare_msi() into a generic operation" by

+Subject: gpio: pca953x: fix IRQ storm on system wake up
+
+From: Emanuele Ghidoli <emanuele.ghidoli@toradex.com>
+
+[ Upstream commit 3e38f946062b4845961ab86b726651b4457b2af8 ]
+
+If an input changes state during wake-up and is used as an interrupt
+source, the IRQ handler reads the volatile input register to clear the
+interrupt mask and deassert the IRQ line. However, the IRQ handler is
+triggered before access to the register is granted, causing the read
+operation to fail.
+
+As a result, the IRQ handler enters a loop, repeatedly printing the
+"failed reading register" message, until `pca953x_resume()` is eventually
+called, which restores the driver context and enables access to
+registers.
+
+Fix by disabling the IRQ line before entering suspend mode, and
+re-enabling it after the driver context is restored in `pca953x_resume()`.
+
+An IRQ can be disabled with disable_irq() and still wake the system as
+long as the IRQ has wake enabled, so the wake-up functionality is
+preserved.
+
+Fixes: b76574300504 ("gpio: pca953x: Restore registers after suspend/resume cycle")

+
+The expression PCC_NUM_RETRIES * pcc_chan->latency is currently being
+evaluated using 32-bit arithmetic.
+
+Since a value of type 'u64' is used to store the eventual result,
+and this result is later sent to the function usecs_to_jiffies with
+input parameter unsigned int, the current data type is too wide to
+store the value of ctx->usecs_lat.
+
+Change the data type of "usecs_lat" to a more suitable (narrower) type.

+Subject: i2c: qup: Vote for interconnect bandwidth to DRAM
+
+From: Stephan Gerhold <stephan.gerhold@kernkonzept.com>
+
+[ Upstream commit d4f35233a6345f62637463ef6e0708f44ffaa583 ]
+
+When the I2C QUP controller is used together with a DMA engine it needs
+to vote for the interconnect path to the DRAM. Otherwise it may be
+unable to access the memory quickly enough.
+
+The requested peak bandwidth is dependent on the I2C core clock.
+
+To avoid sending votes too often the bandwidth is always requested when
+a DMA transfer starts, but dropped only on runtime suspend. Runtime
+suspend should only happen if no transfer is active. After resumption we
+can defer the next vote until the first DMA transfer actually happens.
+
+The implementation is largely identical to the one introduced for
+spi-qup in commit ecdaa9473019 ("spi: qup: Vote for interconnect
+bandwidth to DRAM") since both drivers represent the same hardware
+block.

+The controller driver nacked the master request but didn't emit a
+STOP to end the transaction. The driver shall refuse the unsupported

+Subject: i3c: master: svc: Flush FIFO before sending Dynamic Address
+ Assignment(DAA)
+
+From: Frank Li <Frank.Li@nxp.com>
+
+[ Upstream commit a892ee4cf22a50e1d6988d0464a9a421f3e5db2f ]
+
+Ensure the FIFO is empty before issuing the DAA command to prevent
+incorrect command data from being sent. Align with other data transfers,
+such as svc_i3c_master_start_xfer_locked(), which flushes the FIFO before
+sending a command.

+From: Jens Axboe <axboe@kernel.dk>
+
+[ Upstream commit f024d3a8ded0d8d2129ae123d7a5305c29ca44ce ]
+
+syzbot complains about the cached sq head read, and it's totally right.
+But we don't need to care, it's just reading fdinfo, and reading the
+CQ or SQ tail/head entries are known racy in that they are just a view
+into that very instant and may of course be outdated by the time they
+are reported.
+
+Annotate both the SQ head and CQ tail read with data_race() to avoid
+this syzbot complaint.

+Subject: ipv4: fib: Move fib_valid_key_len() to rtm_to_fib_config().
+
+From: Kuniyuki Iwashima <kuniyu@amazon.com>
+
+[ Upstream commit 254ba7e6032d3fc738050d500b0c1d8197af90ca ]
+
+fib_valid_key_len() is called in the beginning of fib_table_insert()
+or fib_table_delete() to check if the prefix length is valid.
+
+fib_table_insert() and fib_table_delete() are called from 3 paths
+
+ - ip_rt_ioctl()
+ - inet_rtm_newroute() / inet_rtm_delroute()
+ - fib_magic()
+
+In the first ioctl() path, rtentry_to_fib_config() checks the prefix
+length with bad_mask(). Also, fib_magic() always passes the correct
+prefix: 32 or ifa->ifa_prefixlen, which is already validated.
+
+Let's move fib_valid_key_len() to the rtnetlink path, rtm_to_fib_config().
+
+While at it, 2 direct returns in rtm_to_fib_config() are changed to
+goto to match other places in the same function

+Subject: ipv6: save dontfrag in cork
+
+From: Willem de Bruijn <willemb@google.com>
+
+[ Upstream commit a18dfa9925b9ef6107ea3aa5814ca3c704d34a8a ]
+
+When spanning datagram construction over multiple send calls using
+MSG_MORE, per datagram settings are configured on the first send.
+
+That is when ip(6)_setup_cork stores these settings for subsequent use
+in __ip(6)_append_data and others.
+
+The only flag that escaped this was dontfrag. As a result, a datagram
+could be constructed with df=0 on the first sendmsg, but df=1 on a
+next. Which is what cmsg_ip.sh does in an upcoming MSG_MORE test in
+the "diff" scenario.
+
+Changing datagram conditions in the middle of constructing an skb
+makes this already complex code path even more convoluted. It is here
+unintentional. Bring this flag in line with expected sockopt/cmsg
+behavior.
+
+And stop passing ipc6 to __ip6_append_data, to avoid such issues
+in the future. This is already the case for __ip_append_data.
+
+inet6_cork had a 6 byte hole, so the 1B flag has no impact.

+
+[ Upstream commit f757f6011c92b5a01db742c39149bed9e526478f ]
+
+The script previously assumed --file was always the first argument,
+which caused issues when it appeared later. This patch updates the
+parsing logic to scan all arguments to find --file, sets the config
+file correctly, and resets the argument list with the remaining

+
+It also fixes --refresh to respect --file by passing KCONFIG_CONFIG=$FN

+Subject: kconfig: merge_config: use an empty file as initfile
+
+From: Daniel Gomez <da.gomez@samsung.com>
+
+[ Upstream commit a26fe287eed112b4e21e854f173c8918a6a8596d ]
+
+The scripts/kconfig/merge_config.sh script requires an existing
+$INITFILE (or the $1 argument) as a base file for merging Kconfig
+fragments. However, an empty $INITFILE can serve as an initial starting
+point, later referenced by the KCONFIG_ALLCONFIG Makefile variable
+if -m is not used. This variable can point to any configuration file
+containing preset config symbols (the merged output) as stated in
+Documentation/kbuild/kconfig.rst. When -m is used $INITFILE will
+contain just the merge output requiring the user to run make (i.e.
+KCONFIG_ALLCONFIG=<$INITFILE> make <allnoconfig/alldefconfig> or make
+olddefconfig).
+
+Instead of failing when `$INITFILE` is missing, create an empty file and
+use it as the starting point for merges.

+Subject: kernfs: Don't re-lock kernfs_root::kernfs_rwsem in
+ kernfs_fop_readdir().
+
+From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+
+[ Upstream commit 9aab10a0249eab4ec77c6a5e4f66442610c12a09 ]
+
+The readdir operation iterates over all entries and invokes dir_emit()
+for every entry passing kernfs_node::name as argument.
+Since the name argument can change, and become invalid, the
+kernfs_root::kernfs_rwsem lock should not be dropped to prevent renames
+during the operation.
+
+The lock drop around dir_emit() has been initially introduced in commit
+ 1e5289c97bba2 ("sysfs: Cache the last sysfs_dirent to improve readdir scalability v2")
+
+to avoid holding a global lock during a page fault. The lock drop is
+wrong since the support of renames and not a big burden since the lock
+is no longer global.
+
+Don't re-acquire kernfs_root::kernfs_rwsem while copying the name to the
+userpace buffer.

+
+As noted in [0], SeaBIOS (QEMU default) makes a mess of the terminal,
+qboot does not.
+
+It turns out this is actually useful with kunit.py, since the user is

+Subject: libbpf: fix LDX/STX/ST CO-RE relocation size adjustment logic
+
+From: Andrii Nakryiko <andrii@kernel.org>
+
+[ Upstream commit 06096d19ee3897a7e70922580159607fe315da7a ]
+
+Libbpf has a somewhat obscure feature of automatically adjusting the
+"size" of LDX/STX/ST instruction (memory store and load instructions),
+based on originally recorded access size (u8, u16, u32, or u64) and the
+actual size of the field on target kernel. This is meant to facilitate
+using BPF CO-RE on 32-bit architectures (pointers are always 64-bit in
+BPF, but host kernel's BTF will have it as 32-bit type), as well as
+generally supporting safe type changes (unsigned integer type changes
+can be transparently "relocated").
+
+One issue that surfaced only now, 5 years after this logic was
+implemented, is how this all works when dealing with fields that are
+arrays. This isn't all that easy and straightforward to hit (see
+selftests that reproduce this condition), but one of sched_ext BPF
+programs did hit it with innocent looking loop.
+
+Long story short, libbpf used to calculate entire array size, instead of
+making sure to only calculate array's element size. But it's the element
+that is loaded by LDX/STX/ST instructions (1, 2, 4, or 8 bytes), so
+that's what libbpf should check. This patch adjusts the logic for
+arrays and fixed the issue.

+
+From: Nandakumar Edamana <nandakumar@nandakumar.co.in>
+
+[ Upstream commit 236d3910117e9f97ebf75e511d8bcc950f1a4e5f ]
+
+In `set_kcfg_value_str`, an untrusted string is accessed with the assumption
+that it will be at least two characters long due to the presence of checks for
+opening and closing quotes. But the check for the closing quote
+(value[len - 1] != '"') misses the fact that it could be checking the opening
+quote itself in case of an invalid input that consists of just the opening
+quote.
+
+This commit adds an explicit check to make sure the string is at least two
+characters long.

+Subject: libnvdimm/labels: Fix divide error in nd_label_data_init()
+
+From: Robert Richter <rrichter@amd.com>
+
+[ Upstream commit ef1d3455bbc1922f94a91ed58d3d7db440652959 ]
+
+If a faulty CXL memory device returns a broken zero LSA size in its
+memory device information (Identify Memory Device (Opcode 4000h), CXL
+spec. 3.1, 8.2.9.9.1.1), a divide error occurs in the libnvdimm
+driver:
+
+ Oops: divide error: 0000 [#1] PREEMPT SMP NOPTI
+ RIP: 0010:nd_label_data_init+0x10e/0x800 [libnvdimm]
+
+Code and flow:
+
+1) CXL Command 4000h returns LSA size = 0
+2) config_size is assigned to zero LSA size (CXL pmem driver):
+
+drivers/cxl/pmem.c: .config_size = mds->lsa_size,
+
+3) max_xfer is set to zero (nvdimm driver):
+
+drivers/nvdimm/label.c: max_xfer = min_t(size_t, ndd->nsarea.max_xfer, config_size);
+
+4) A subsequent DIV_ROUND_UP() causes a division by zero:
+
+drivers/nvdimm/label.c: /* Make our initial read size a multiple of max_xfer size */
+drivers/nvdimm/label.c: read_size = min(DIV_ROUND_UP(read_size, max_xfer) * max_xfer,
+drivers/nvdimm/label.c- config_size);
+
+Fix this by checking the config size parameter by extending an
+existing check.

+Subject: lockdep: Fix wait context check on softirq for PREEMPT_RT
+
+From: Ryo Takakura <ryotkkr98@gmail.com>
+
+[ Upstream commit 61c39d8c83e2077f33e0a2c8980a76a7f323f0ce ]
+
+Since:
+
+ 0c1d7a2c2d32 ("lockdep: Remove softirq accounting on PREEMPT_RT.")
+
+the wait context test for mutex usage within "in softirq context" fails
+as it references @softirq_context:
+
+ | wait context tests |
+ --------------------------------------------------------------------------
+ | rcu | raw | spin |mutex |
+ --------------------------------------------------------------------------
+ in hardirq context: ok | ok | ok | ok |
+ in hardirq context (not threaded): ok | ok | ok | ok |
+ in softirq context: ok | ok | ok |FAILED|
+
+As a fix, add lockdep map for BH disabled section. This fixes the
+issue by letting us catch cases when local_bh_disable() gets called
+with preemption disabled where local_lock doesn't get acquired.
+In the case of "in softirq context" selftest, local_bh_disable() was
+being called with preemption disable as it's early in the boot.
+
+[ boqun: Move the lockdep annotations into __local_bh_*() to avoid false
+ positives because of unpaired local_bh_disable() reported by
+ Borislav Petkov and Peter Zijlstra, and make bh_lock_map
+ only exist for PREEMPT_RT. ]

+From: Depeng Shao <quic_depengs@quicinc.com>
+
+[ Upstream commit 2f1361f862a68063f37362f1beb400e78e289581 ]
+
+There is no CSID TPG on some SoCs, so the v4l2 ctrl in CSID driver
+shouldn't be registered. Checking the supported TPG modes to indicate
+if the TPG hardware exists or not and only registering v4l2 ctrl for
+CSID only when the TPG hardware is present.

+
+From: Hans Verkuil <hverkuil@xs4all.nl>
+
+[ Upstream commit e4740118b752005cbed339aec9a1d1c43620e0b9 ]
+
+Artem reported that the CPU load was 100% when capturing from
+vivid at low resolution with ffmpeg.
+
+This was caused by:
+
+while (time_is_after_jiffies(cur_jiffies + wait_jiffies) &&
+ !kthread_should_stop())
+ schedule();
+
+If there are no other processes running that can be scheduled,
+then this is basically a busy-loop.
+
+Change it to wait_event_interruptible_timeout() which doesn't
+have that problem.

+Subject: MIPS: pm-cps: Use per-CPU variables as per-CPU, not per-core
+
+From: Paul Burton <paulburton@kernel.org>
+
+[ Upstream commit 00a134fc2bb4a5f8fada58cf7ff4259149691d64 ]
+
+The pm-cps code has up until now used per-CPU variables indexed by core,
+rather than CPU number, in order to share data amongst sibling CPUs (ie.
+VPs/threads in a core). This works fine for single cluster systems, but
+with multi-cluster systems a core number is no longer unique in the
+system, leading to sharing between CPUs that are not actually siblings.
+
+Avoid this issue by using per-CPU variables as they are more generally
+used - ie. access them using CPU numbers rather than core numbers.
+Sharing between siblings is then accomplished by:
+ - Assigning the same pointer to entries for each sibling CPU for the
+ nc_asm_enter & ready_count variables, which allow this by virtue of
+ being per-CPU pointers.
+
+ - Indexing by the first CPU set in a CPUs cpu_sibling_map in the case
+ of pm_barrier, for which we can't use the previous approach because
+ the per-CPU variable is not a pointer.

+
+On MIPS system, most of the syscall function name begin with prefix
+sys_. Some syscalls are special such as clone/fork, function name of
+these begin with __sys_. Since scratch registers need be saved in
+stack when these system calls happens.
+
+With ftrace system call method, system call functions are declared with
+SYSCALL_DEFINEx, metadata of the system call symbol name begins with
+sys_. Here mips specific function arch_syscall_match_sym_name is used to
+compare function name between sys_call_table[] and metadata of syscall
+symbol.

+
+From: Kaustabh Chakraborty <kauschluss@disroot.org>
+
+[ Upstream commit 7cbe799ac10fd8be85af5e0615c4337f81e575f3 ]
+
+Add support for Exynos7870 DW MMC controllers, for both SMU and non-SMU
+variants. These controllers require a quirk to access 64-bit FIFO in 32-bit
+accesses (DW_MMC_QUIRK_FIFO64_32).

+
+From: Erick Shepherd <erick.shepherd@ni.com>
+
+[ Upstream commit 31e75ed964582257f59156ce6a42860e1ae4cc39 ]
+
+The SD spec version 6.0 section 6.4.1.5 requires that Vdd must be
+lowered to less than 0.5V for a minimum of 1 ms when powering off a
+card. Increase wait to 15 ms so that voltage has time to drain down
+to 0.5V and cards can power off correctly. Issues with voltage drain
+time were only observed on Apollo Lake and Bay Trail host controllers
+so this fix is limited to those devices.

+Subject: net: enetc: refactor bulk flipping of RX buffers to separate function
+
+From: Vladimir Oltean <vladimir.oltean@nxp.com>
+
+[ Upstream commit 1d587faa5be7e9785b682cc5f58ba8f4100c13ea ]
+
+This small snippet of code ensures that we do something with the array
+of RX software buffer descriptor elements after passing the skb to the
+stack. In this case, we see if the other half of the page is reusable,
+and if so, we "turn around" the buffers, making them directly usable by
+enetc_refill_rx_ring() without going to enetc_new_page().
+
+We will need to perform this kind of buffer flipping from a new code
+path, i.e. from XDP_PASS. Currently, enetc_build_skb() does it there
+buffer by buffer, but in a subsequent change we will stop using
+enetc_build_skb() for XDP_PASS.

+Subject: net: ethernet: mtk_ppe_offload: Allow QinQ, double ETH_P_8021Q only
+
+From: Eric Woudstra <ericwouds@gmail.com>
+
+[ Upstream commit 7fe0353606d77a32c4c7f2814833dd1c043ebdd2 ]
+
+mtk_foe_entry_set_vlan() in mtk_ppe.c already supports double vlan
+tagging, but mtk_flow_offload_replace() in mtk_ppe_offload.c only allows
+for 1 vlan tag, optionally in combination with pppoe and dsa tags.
+
+However, mtk_foe_entry_set_vlan() only allows for setting the vlan id.
+The protocol cannot be set, it is always ETH_P_8021Q, for inner and outer
+tag. This patch adds QinQ support to mtk_flow_offload_replace(), only in
+the case that both inner and outer tags are ETH_P_8021Q.
+
+Only PPPoE-in-Q (as before) and Q-in-Q are allowed. A combination
+of PPPoE and Q-in-Q is not allowed.

+Subject: net/mlx5e: reduce rep rxq depth to 256 for ECPF
+
+From: William Tu <witu@nvidia.com>
+
+[ Upstream commit b9cc8f9d700867aaa77aedddfea85e53d5e5d584 ]
+
+By experiments, a single queue representor netdev consumes kernel
+memory around 2.8MB, and 1.8MB out of the 2.8MB is due to page
+pool for the RXQ. Scaling to a thousand representors consumes 2.8GB,
+which becomes a memory pressure issue for embedded devices such as
+BlueField-2 16GB / BlueField-3 32GB memory.
+
+Since representor netdevs mostly handles miss traffic, and ideally,
+most of the traffic will be offloaded, reduce the default non-uplink
+rep netdev's RXQ default depth from 1024 to 256 if mdev is ecpf eswitch
+manager. This saves around 1MB of memory per regular RQ,
+(1024 - 256) * 2KB, allocated from page pool.
+
+With rxq depth of 256, the netlink page pool tool reports
+$./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \
+ --dump page-pool-get
+ {'id': 277,
+ 'ifindex': 9,
+ 'inflight': 128,
+ 'inflight-mem': 786432,
+ 'napi-id': 775}]
+
+This is due to mtu 1500 + headroom consumes half pages, so 256 rxq
+entries consumes around 128 pages (thus create a page pool with
+size 128), shown above at inflight.
+
+Note that each netdev has multiple types of RQs, including
+Regular RQ, XSK, PTP, Drop, Trap RQ. Since non-uplink representor
+only supports regular rq, this patch only changes the regular RQ's
+default depth.

+
+[ Upstream commit a38cc5706fb9f7dc4ee3a443f61de13ce1e410ed ]
+
+By default, the mq netdev creates a pfifo_fast qdisc. On a
+system with 16 core, the pfifo_fast with 3 bands consumes
+16 * 3 * 8 (size of pointer) * 1024 (default tx queue len)
+= 393KB. The patch sets the tx qlen to representor default
+value, 128 (1<<MLX5E_REP_PARAMS_DEF_LOG_SQ_SIZE), which
+consumes 16 * 3 * 8 * 128 = 49KB, saving 344KB for each

+Subject: net: phylink: use pl->link_interface in phylink_expects_phy()
+
+From: Choong Yong Liang <yong.liang.choong@linux.intel.com>
+
+[ Upstream commit b63263555eaafbf9ab1a82f2020bbee872d83759 ]
+
+The phylink_expects_phy() function allows MAC drivers to check if they are
+expecting a PHY to attach. The checking condition in phylink_expects_phy()
+aims to achieve the same result as the checking condition in
+phylink_attach_phy().
+
+However, the checking condition in phylink_expects_phy() uses
+pl->link_config.interface, while phylink_attach_phy() uses
+pl->link_interface.
+
+Initially, both pl->link_interface and pl->link_config.interface are set
+to SGMII, and pl->cfg_link_an_mode is set to MLO_AN_INBAND.
+
+When the interface switches from SGMII to 2500BASE-X,
+pl->link_config.interface is updated by phylink_major_config().
+At this point, pl->cfg_link_an_mode remains MLO_AN_INBAND, and
+pl->link_config.interface is set to 2500BASE-X.
+Subsequently, when the STMMAC interface is taken down
+administratively and brought back up, it is blocked by
+phylink_expects_phy().
+
+Since phylink_expects_phy() and phylink_attach_phy() aim to achieve the
+same result, phylink_expects_phy() should check pl->link_interface,
+which never changes, instead of pl->link_config.interface, which is
+updated by phylink_major_config().

+Subject: net/smc: use the correct ndev to find pnetid by pnetid table
+
+From: Guangguan Wang <guangguan.wang@linux.alibaba.com>
+
+[ Upstream commit bfc6c67ec2d64d0ca4e5cc3e1ac84298a10b8d62 ]
+
+When using smc_pnet in SMC, it will only search the pnetid in the
+base_ndev of the netdev hierarchy(both HW PNETID and User-defined
+sw pnetid). This may not work for some scenarios when using SMC in
+container on cloud environment.
+In container, there have choices of different container network,
+such as directly using host network, virtual network IPVLAN, veth,
+etc. Different choices of container network have different netdev
+hierarchy. Examples of netdev hierarchy show below. (eth0 and eth1
+in host below is the netdev directly related to the physical device).

+ | host |_________| |
+ ---------------------------------
+ netdev hierarchy if using veth
+Due to some reasons, the eth1 in host is not RDMA attached netdevice,
+pnetid is needed to map the eth1(in host) with RDMA device so that POD
+can do SMC-R. Because the eth1(in host) is managed by CNI plugin(such
+as Terway, network management plugin in container environment), and in
+cloud environment the eth(in host) can dynamically be inserted by CNI
+when POD create and dynamically be removed by CNI when POD destroy and
+no POD related to the eth(in host) anymore. It is hard to config the
+pnetid to the eth1(in host). But it is easy to config the pnetid to the
+netdevice which can be seen in POD. When do SMC-R, both the container
+directly using host network and the container using veth network can
+successfully match the RDMA device, because the configured pnetid netdev
+is a base_ndev. But the container using IPVLAN can not successfully
+match the RDMA device and 0x03030000 fallback happens, because the
+configured pnetid netdev is not a base_ndev. Additionally, if config
+pnetid to the eth1(in host) also can not work for matching RDMA device
+when using veth network and doing SMC-R in POD.
+
+To resolve the problems list above, this patch extends to search user
+-defined sw pnetid in the clc handshake ndev when no pnetid can be found
+in the base_ndev, and the base_ndev take precedence over ndev for backward
+compatibility. This patch also can unify the pnetid setup of different
+network choices list above in container(Config user-defined sw pnetid in
+the netdevice can be seen in POD).

+Subject: netfilter: conntrack: Bound nf_conntrack sysctl writes
+
+From: Nicolas Bouchinet <nicolas.bouchinet@ssi.gouv.fr>
+
+[ Upstream commit 8b6861390ffee6b8ed78b9395e3776c16fec6579 ]
+
+nf_conntrack_max and nf_conntrack_expect_max sysctls were authorized to
+be written any negative value, which would then be stored in the
+unsigned int variables nf_conntrack_max and nf_ct_expect_max variables.
+
+While the do_proc_dointvec_conv function is supposed to limit writing
+handled by proc_dointvec proc_handler to INT_MAX. Such a negative value
+being written in an unsigned int leads to a very high value, exceeding
+this limit.
+
+Moreover, the nf_conntrack_expect_max sysctl documentation specifies the
+minimum value is 1.
+
+The proc_handlers have thus been updated to proc_dointvec_minmax in
+order to specify the following write bounds :
+
+* Bound nf_conntrack_max sysctl writings between SYSCTL_ZERO
+ and SYSCTL_INT_MAX.
+
+* Bound nf_conntrack_expect_max sysctl writings between SYSCTL_ONE
+ and SYSCTL_INT_MAX as defined in the sysctl documentation.
+
+With this patch applied, sysctl writes outside the defined in the bound
+will thus lead to a write error :
+
+```
+sysctl -w net.netfilter.nf_conntrack_expect_max=-1
+sysctl: setting key "net.netfilter.nf_conntrack_expect_max": Invalid argument

+
+[ Upstream commit 0af5fb5ed3d2fd9e110c6112271f022b744a849a ]
+
+If a containerised process is killed and causes an ENETUNREACH or
+ENETDOWN error to be propagated to the state manager, then mark the
+nfs_client as being dead so that we don't loop in functions that are
+expecting recovery to succeed.

+Subject: nvme: map uring_cmd data even if address is 0
+
+From: Xinyu Zhang <xizhang@purestorage.com>
+
+[ Upstream commit 99fde895ff56ac2241e7b7b4566731d72f2fdaa7 ]
+
+When using kernel registered bvec fixed buffers, the "address" is
+actually the offset into the bvec rather than userspace address.
+Therefore it can be 0.
+
+We can skip checking whether the address is NULL before mapping
+uring_cmd data. Bad userspace address will be handled properly later when
+the user buffer is imported.
+
+With this patch, we will be able to use the kernel registered bvec fixed
+buffers in io_uring NVMe passthru with ublk zero-copy support.

+Subject: nvmet-tcp: don't restore null sk_state_change
+
+From: Alistair Francis <alistair.francis@wdc.com>
+
+[ Upstream commit 46d22b47df2741996af277a2838b95f130436c13 ]
+
+queue->state_change is set as part of nvmet_tcp_set_queue_sock(), but if
+the TCP connection isn't established when nvmet_tcp_set_queue_sock() is
+called then queue->state_change isn't set and sock->sk->sk_state_change
+isn't replaced.
+
+As such we don't need to restore sock->sk->sk_state_change if
+queue->state_change is NULL.
+
+This avoids NULL pointer dereferences such as this:

+
+From: Josh Poimboeuf <jpoimboe@kernel.org>
+
+[ Upstream commit e1a9dda74dbffbc3fa2069ff418a1876dc99fb14 ]
+
+If opts.uaccess isn't set, the uaccess validation is disabled, but only
+partially: it doesn't read the uaccess_safe_builtin list but still tries
+to do the validation. Disable it completely to prevent false warnings.

+Subject: PCI: dwc: ep: Ensure proper iteration over outbound map windows
+
+From: Frank Li <Frank.Li@nxp.com>
+
+[ Upstream commit f3e1dccba0a0833fc9a05fb838ebeb6ea4ca0e1a ]
+
+Most systems' PCIe outbound map windows have non-zero physical addresses,
+but the possibility of encountering zero increased after following commit
+("PCI: dwc: Use parent_bus_offset").
+
+'ep->outbound_addr[n]', representing 'parent_bus_address', might be 0 on
+some hardware, which trims high address bits through bus fabric before
+sending to the PCIe controller.
+
+Replace the iteration logic with 'for_each_set_bit()' to ensure only
+allocated map windows are iterated when determining the ATU index from a
+given address.

+
+MSI remapping bypass (directly configuring MSI entries for devices on the
+VMD bus) won't work under Xen, as Xen is not aware of devices in such bus,
+and hence cannot configure the entries using the pIRQ interface in the PV
+case, and in the PVH case traps won't be setup for MSI entries for such
+devices.
+
+Until Xen is aware of devices in the VMD bus prevent the
+VMD_FEAT_CAN_BYPASS_MSI_REMAP capability from being used when running as
+any kind of Xen guest.
+
+The MSI remapping bypass is an optional feature of VMD bridges, and hence
+when running under Xen it will be masked and devices will be forced to
+redirect its interrupts from the VMD bridge. That mode of operation must
+always be supported by VMD bridges and works when Xen is not aware of
+devices behind the VMD bridge.

+Subject: perf/amd/ibs: Fix perf_ibs_op.cnt_mask for CurCnt
+
+From: Ravi Bangoria <ravi.bangoria@amd.com>
+
+[ Upstream commit 46dcf85566170d4528b842bf83ffc350d71771fa ]
+
+IBS Op uses two counters: MaxCnt and CurCnt. MaxCnt is programmed with
+the desired sample period. IBS hw generates sample when CurCnt reaches
+to MaxCnt. The size of these counter used to be 20 bits but later they
+were extended to 27 bits. The 7 bit extension is indicated by CPUID
+Fn8000_001B_EAX[6 / OpCntExt].
+
+perf_ibs->cnt_mask variable contains bit masks for MaxCnt and CurCnt.
+But IBS driver does not set upper 7 bits of CurCnt in cnt_mask even
+when OpCntExt CPUID bit is set. Fix this.
+
+IBS driver uses cnt_mask[CurCnt] bits only while disabling an event.
+Fortunately, CurCnt bits are not read from MSR while re-enabling the
+event, instead MaxCnt is programmed with desired period and CurCnt is
+set to 0. Hence, we did not see any issues so far.

+Subject: perf: Avoid the read if the count is already updated
+
+From: Peter Zijlstra (Intel) <peterz@infradead.org>
+
+[ Upstream commit 8ce939a0fa194939cc1f92dbd8bc1a7806e7d40a ]
+
+The event may have been updated in the PMU-specific implementation,
+e.g., Intel PEBS counters snapshotting. The common code should not
+read and overwrite the value.
+
+The PERF_SAMPLE_READ in the data->sample_type can be used to detect
+whether the PMU-specific value is available. If yes, avoid the
+pmu->read() in the common code. Add a new flag, skip_read, to track the
+case.
+
+Factor out a perf_pmu_read() to clean up the code.

+Subject: perf/hw_breakpoint: Return EOPNOTSUPP for unsupported breakpoint type
+
+From: Saket Kumar Bhaskar <skb99@linux.ibm.com>
+
+[ Upstream commit 061c991697062f3bf87b72ed553d1d33a0e370dd ]
+
+Currently, __reserve_bp_slot() returns -ENOSPC for unsupported
+breakpoint types on the architecture. For example, powerpc
+does not support hardware instruction breakpoints. This causes
+the perf_skip BPF selftest to fail, as neither ENOENT nor
+EOPNOTSUPP is returned by perf_event_open for unsupported
+breakpoint types. As a result, the test that should be skipped
+for this arch is not correctly identified.
+
+To resolve this, hw_breakpoint_event_init() should exit early by
+checking for unsupported breakpoint types using
+hw_breakpoint_slots_cached() and return the appropriate error
+(-EOPNOTSUPP).

+[ Upstream commit d58c04e305afbaa9dda7969151f06c4efe2c98b0 ]
+
+As reported by Damon Ding, the phy_get_mode() call doesn't work as
+expected unless the PHY driver has a .set_mode() call. This prompts PHY
+drivers to have empty stubs for .set_mode() for the sake of being able

+
+Make .set_mode() callback truly optional and update PHY's mode even if

+Subject: phy: renesas: rcar-gen3-usb2: Add support to initialize the bus
+
+From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>
+
+[ Upstream commit 4eae16375357a2a7e8501be5469532f7636064b3 ]
+
+The Renesas RZ/G3S need to initialize the USB BUS before transferring data
+due to hardware limitation. As the register that need to be touched for
+this is in the address space of the USB PHY, and the UBS PHY need to be
+initialized before any other USB drivers handling data transfer, add
+support to initialize the USB BUS.
+
+As the USB PHY is probed before any other USB drivers that enables
+clocks and de-assert the reset signals and the BUS initialization is done
+in the probe phase, we need to add code to de-assert reset signal and
+runtime resume the device (which enables its clocks) before accessing
+the registers.
+
+As the reset signals are not required by the USB PHY driver for the other
+USB PHY hardware variants, the reset signals and runtime PM was handled
+only in the function that initialize the USB BUS.
+
+The PHY initialization was done right after runtime PM enable to have
+all in place when the PHYs are registered.

+Subject: phy: renesas: rcar-gen3-usb2: Lock around hardware registers and
+ driver data
+
+From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>
+
+[ Upstream commit 55a387ebb9219cbe4edfa8ba9996ccb0e7ad4932 ]
+
+The phy-rcar-gen3-usb2 driver exposes four individual PHYs that are
+requested and configured by PHY users. The struct phy_ops APIs access the
+same set of registers to configure all PHYs. Additionally, PHY settings can
+be modified through sysfs or an IRQ handler. While some struct phy_ops APIs
+are protected by a driver-wide mutex, others rely on individual
+PHY-specific mutexes.
+
+This approach can lead to various issues, including:
+1/ the IRQ handler may interrupt PHY settings in progress, racing with
+ hardware configuration protected by a mutex lock
+2/ due to msleep(20) in rcar_gen3_init_otg(), while a configuration thread
+ suspends to wait for the delay, another thread may try to configure
+ another PHY (with phy_init() + phy_power_on()); re-running the
+ phy_init() goes to the exact same configuration code, re-running the
+ same hardware configuration on the same set of registers (and bits)
+ which might impact the result of the msleep for the 1st configuring
+ thread
+3/ sysfs can configure the hardware (though role_store()) and it can
+ still race with the phy_init()/phy_power_on() APIs calling into the
+ drivers struct phy_ops
+
+To address these issues, add a spinlock to protect hardware register access
+and driver private data structures (e.g., calls to
+rcar_gen3_is_any_rphy_initialized()). Checking driver-specific data remains
+necessary as all PHY instances share common settings. With this change,
+the existing mutex protection is removed and the cleanup.h helpers are
+used.
+
+While at it, to keep the code simpler, do not skip
+regulator_enable()/regulator_disable() APIs in
+rcar_gen3_phy_usb2_power_on()/rcar_gen3_phy_usb2_power_off() as the
+regulators enable/disable operations are reference counted anyway.

+Subject: phy: renesas: rcar-gen3-usb2: Move IRQ request in probe
+
+From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>
+
+[ Upstream commit de76809f60cc938d3580bbbd5b04b7d12af6ce3a ]
+
+Commit 08b0ad375ca6 ("phy: renesas: rcar-gen3-usb2: move IRQ registration
+to init") moved the IRQ request operation from probe to
+struct phy_ops::phy_init API to avoid triggering interrupts (which lead to
+register accesses) while the PHY clocks (enabled through runtime PM APIs)
+are not active. If this happens, it results in a synchronous abort.
+
+One way to reproduce this issue is by enabling CONFIG_DEBUG_SHIRQ, which
+calls free_irq() on driver removal.
+
+Move the IRQ request and free operations back to probe, and take the
+runtime PM state into account in IRQ handler. This commit is preparatory
+for the subsequent fixes in this series.

+Subject: pinctrl: devicetree: do not goto err when probing hogs in
+ pinctrl_dt_to_map
+
+From: Valentin Caron <valentin.caron@foss.st.com>
+
+[ Upstream commit c98868e816209e568c9d72023ba0bc1e4d96e611 ]
+
+Cross case in pinctrl framework make impossible to an hogged pin and
+another, not hogged, used within the same device-tree node. For example
+with this simplified device-tree :
+
+ &pinctrl {
+ pinctrl_pin_1: pinctrl-pin-1 {
+ pins = "dummy-pinctrl-pin";
+ };
+ };
+
+ &rtc {
+ pinctrl-names = "default"
+ pinctrl-0 = <&pinctrl_pin_1 &rtc_pin_1>
+
+ rtc_pin_1: rtc-pin-1 {
+ pins = "dummy-rtc-pin";
+ };
+ };
+
+"pinctrl_pin_1" configuration is never set. This produces this path in
+the code:
+
+ really_probe()
+ pinctrl_bind_pins()
+ | devm_pinctrl_get()
+ | pinctrl_get()
+ | create_pinctrl()
+ | pinctrl_dt_to_map()
+ | // Hog pin create an abort for all pins of the node
+ | ret = dt_to_map_one_config()
+ | | /* Do not defer probing of hogs (circular loop) */
+ | | if (np_pctldev == p->dev->of_node)
+ | | return -ENODEV;
+ | if (ret)
+ | goto err
+ |
+ call_driver_probe()
+ stm32_rtc_probe()
+ pinctrl_enable()
+ pinctrl_claim_hogs()
+ create_pinctrl()
+ for_each_maps(maps_node, i, map)
+ // Not hog pin is skipped
+ if (pctldev && strcmp(dev_name(pctldev->dev),
+ map->ctrl_dev_name))
+ continue;
+
+At the first call of create_pinctrl() the hogged pin produces an abort to
+avoid a defer of hogged pins. All other pin configurations are trashed.
+
+At the second call, create_pinctrl is now called with pctldev parameter to
+get hogs, but in this context only hogs are set. And other pins are
+skipped.
+
+To handle this, do not produce an abort in the first call of
+create_pinctrl(). Classic pin configuration will be set in
+pinctrl_bind_pins() context. And the hogged pin configuration will be set
+in pinctrl_claim_hogs() context.

+Subject: pinctrl: meson: define the pull up/down resistor value as 60 kOhm
+
+From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
+
+[ Upstream commit e56088a13708757da68ad035269d69b93ac8c389 ]
+
+The public datasheets of the following Amlogic SoCs describe a typical
+resistor value for the built-in pull up/down resistor:
+- Meson8/8b/8m2: not documented
+- GXBB (S905): 60 kOhm
+- GXL (S905X): 60 kOhm
+- GXM (S912): 60 kOhm
+- G12B (S922X): 60 kOhm
+- SM1 (S905D3): 60 kOhm
+
+The public G12B and SM1 datasheets additionally state min and max
+values:
+- min value: 50 kOhm for both, pull-up and pull-down
+- max value for the pull-up: 70 kOhm
+- max value for the pull-down: 130 kOhm
+
+Use 60 kOhm in the pinctrl-meson driver as well so it's shown in the
+debugfs output. It may not be accurate for Meson8/8b/8m2 but in reality
+60 kOhm is closer to the actual value than 1 Ohm.

+Subject: pinctrl-tegra: Restore SFSEL bit when freeing pins
+
+From: Prathamesh Shete <pshete@nvidia.com>
+
+[ Upstream commit c12bfa0fee65940b10ff5187349f76c6f6b1df9c ]
+
+Each pin can be configured as a Special Function IO (SFIO) or GPIO,
+where the SFIO enables the pin to operate in alternative modes such as
+I2C, SPI, etc.
+
+The current implementation sets all the pins back to SFIO mode
+even if they were initially in GPIO mode. This can cause glitches
+on the pins when pinctrl_gpio_free() is called.
+
+Avoid these undesired glitches by storing the pin's SFIO/GPIO
+state on GPIO request and restoring it on GPIO free.

+Subject: rcu: handle quiescent states for PREEMPT_RCU=n, PREEMPT_COUNT=y
+
+From: Ankur Arora <ankur.a.arora@oracle.com>
+
+[ Upstream commit 83b28cfe796464ebbde1cf7916c126da6d572685 ]
+
+With PREEMPT_RCU=n, cond_resched() provides urgently needed quiescent
+states for read-side critical sections via rcu_all_qs().
+One reason why this was needed: lacking preempt-count, the tick
+handler has no way of knowing whether it is executing in a
+read-side critical section or not.
+
+With (PREEMPT_LAZY=y, PREEMPT_DYNAMIC=n), we get (PREEMPT_COUNT=y,
+PREEMPT_RCU=n). In this configuration cond_resched() is a stub and
+does not provide quiescent states via rcu_all_qs().
+(PREEMPT_RCU=y provides this information via rcu_read_unlock() and
+its nesting counter.)
+
+So, use the availability of preempt_count() to report quiescent states
+in rcu_flavor_sched_clock_irq().

+Subject: RDMA/core: Fix best page size finding when it can cross SG entries
+
+From: Michael Margolin <mrgolin@amazon.com>
+
+[ Upstream commit 486055f5e09df959ad4e3aa4ee75b5c91ddeec2e ]
+
+A single scatter-gather entry is limited by a 32 bits "length" field
+that is practically 4GB - PAGE_SIZE. This means that even when the
+memory is physically contiguous, we might need more than one entry to
+represent it. Additionally when using dmabuf, the sg_table might be
+originated outside the subsystem and optimized for other needs.
+
+For instance an SGT of 16GB GPU continuous memory might look like this:
+(a real life example)
+
+dma_address 34401400000, length fffff000
+dma_address 345013ff000, length fffff000
+dma_address 346013fe000, length fffff000
+dma_address 347013fd000, length fffff000
+dma_address 348013fc000, length 4000
+
+Since ib_umem_find_best_pgsz works within SG entries, in the above case
+we will result with the worst possible 4KB page size.
+
+Fix this by taking into consideration only the alignment of addresses of
+real discontinuity points rather than treating SG entries as such, and
+adjust the page iterator to correctly handle cross SG entry pages.
+
+There is currently an assumption that drivers do not ask for pages
+bigger than maximal DMA size supported by their devices.

+Subject: RDMA/uverbs: Propagate errors from rdma_lookup_get_uobject()
+
+From: Maher Sanalla <msanalla@nvidia.com>
+
+[ Upstream commit 81f8f7454ad9e0bf95efdec6542afdc9a6ab1e24 ]
+
+Currently, the IB uverbs API calls uobj_get_uobj_read(), which in turn
+uses the rdma_lookup_get_uobject() helper to retrieve user objects.
+In case of failure, uobj_get_uobj_read() returns NULL, overriding the
+error code from rdma_lookup_get_uobject(). The IB uverbs API then
+translates this NULL to -EINVAL, masking the actual error and
+complicating debugging. For example, applications calling ibv_modify_qp
+that fails with EBUSY when retrieving the QP uobject will see the
+overridden error code EINVAL instead, masking the actual error.
+
+Furthermore, based on rdma-core commit:
+"2a22f1ced5f3 ("Merge pull request #1568 from jakemoroni/master")"
+Kernel's IB uverbs return values are either ignored and passed on as is
+to application or overridden with other errnos in a few cases.
+
+Thus, to improve error reporting and debuggability, propagate the
+original error from rdma_lookup_get_uobject() instead of replacing it
+with EINVAL.

+Subject: regulator: ad5398: Add device tree support
+
+From: Isaac Scott <isaac.scott@ideasonboard.com>
+
+[ Upstream commit 5a6a461079decea452fdcae955bccecf92e07e97 ]
+
+Previously, the ad5398 driver used only platform_data, which is
+deprecated in favour of device tree. This caused the AD5398 to fail to
+probe as it could not load its init_data. If the AD5398 has a device
+tree node, pull the init_data from there using
+of_get_regulator_init_data.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit

+[ Upstream commit 65991ea8a6d1e68effdc01d95ebe39f1653f7b71 ]
+
+Both MSM8974 and MSM8226 have only CX as power domain with MX & PX being
+handled as regulators. Handle this case by reodering pd_names to have CX
+first, and handling that the driver core will already attach a single
+power domain internally.

+Subject: s390/vfio-ap: Fix no AP queue sharing allowed message written to
+ kernel log
+
+From: Anthony Krowiak <akrowiak@linux.ibm.com>
+
+[ Upstream commit d33d729afcc8ad2148d99f9bc499b33fd0c0d73b ]
+
+An erroneous message is written to the kernel log when either of the
+following actions are taken by a user:
+
+1. Assign an adapter or domain to a vfio_ap mediated device via its sysfs
+ assign_adapter or assign_domain attributes that would result in one or
+ more AP queues being assigned that are already assigned to a different
+ mediated device. Sharing of queues between mdevs is not allowed.
+
+2. Reserve an adapter or domain for the host device driver via the AP bus
+ driver's sysfs apmask or aqmask attribute that would result in providing
+ host access to an AP queue that is in use by a vfio_ap mediated device.
+ Reserving a queue for a host driver that is in use by an mdev is not
+ allowed.
+
+In both cases, the assignment will return an error; however, a message like
+the following is written to the kernel log:
+
+vfio_ap_mdev e1839397-51a0-4e3c-91e0-c3b9c3d3047d: Userspace may not
+re-assign queue 00.0028 already assigned to \
+e1839397-51a0-4e3c-91e0-c3b9c3d3047d
+
+Notice the mdev reporting the error is the same as the mdev identified
+in the message as the one to which the queue is being assigned.
+It is perfectly okay to assign a queue to an mdev to which it is
+already assigned; the assignment is simply ignored by the vfio_ap device
+driver.
+
+This patch logs more descriptive and accurate messages for both 1 and 2
+above to the kernel log:
+
+Example for 1:
+vfio_ap_mdev 0fe903a0-a323-44db-9daf-134c68627d61: Userspace may not assign
+queue 00.0033 to mdev: already assigned to \
+62177883-f1bb-47f0-914d-32a22e3a8804
+
+Example for 2:
+vfio_ap_mdev 62177883-f1bb-47f0-914d-32a22e3a8804: Can not reserve queue
+00.0033 for host driver: in use by mdev

+
+From: Justin Tee <justin.tee@broadcom.com>
+
+[ Upstream commit 56c3d809b7b450379162d0b8a70bbe71ab8db706 ]
+
+After a port swap between separate fabrics, there may be multiple nodes in
+the vport's fc_nodes list with the same fabric well known address.
+Duplication is temporary and eventually resolves itself after dev_loss_tmo
+expires, but nameserver queries may still occur before dev_loss_tmo. This
+possibly results in returning stale fabric ndlp objects. Fix by adding an
+nlp_state check to ensure the ndlp search routine returns the correct newer
+allocated ndlp fabric object.

+
+Some of the allowed operations put the tape into a known position to
+continue operation assuming only the tape position has changed. But reset
+sets partition, density and block size to drive default values. These
+should be restored to the values before reset.
+
+Normally the current block size and density are stored by the drive. If
+the settings have been changed, the changed values have to be saved by the
+driver across reset.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit

+From: Kai Mäkisara <Kai.Makisara@kolumbus.fi>
+
+[ Upstream commit 8db816c6f176321e42254badd5c1a8df8bfcfdb4 ]
+
+In the days when SCSI-2 was emerging, some drives did claim SCSI-2 but did
+not correctly implement it. The st driver first tries MODE SELECT with the
+page format bit set to set the block descriptor. If not successful, the
+non-page format is tried.
+
+The test only tests the sense code and this triggers also from illegal
+parameter in the parameter list. The test is limited to "old" devices and
+made more strict to remove false alarms.

+[ Upstream commit f2858f308131a09e33afb766cd70119b5b900569 ]
+
+"sockmap_ktls disconnect_after_delete" test has been failing on BPF CI
+after recent merges from netdev:
+* https://github.com/kernel-patches/bpf/actions/runs/14458537639
+* https://github.com/kernel-patches/bpf/actions/runs/14457178732
+
+It happens because disconnect has been disabled for TLS [1], and it
+renders the test case invalid.
+
+Removing all the test code creates a conflict between bpf and
+bpf-next, so for now only remove the offending assert [2].
+
+The test will be removed later on bpf-next.

+Split mctrl_gpio_disable_ms into two differents APIs, a non-blocking one
+and a blocking one. Replace mctrl_gpio_disable_ms calls with the
+relevant version depending on whether the call is protected by some port
+lock.

+Subject: serial: sh-sci: Update the suspend/resume support
+
+From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>
+
+[ Upstream commit 22a6984c5b5df8eab864d7f3e8b94d5a554d31ab ]
+
+The Renesas RZ/G3S supports a power saving mode where power to most of the
+SoC components is turned off. When returning from this power saving mode,
+SoC components need to be re-configured.
+
+The SCIFs on the Renesas RZ/G3S need to be re-configured as well when
+returning from this power saving mode. The sh-sci code already configures
+the SCIF clocks, power domain and registers by calling uart_resume_port()
+in sci_resume(). On suspend path the SCIF UART ports are suspended
+accordingly (by calling uart_suspend_port() in sci_suspend()). The only
+missing setting is the reset signal. For this assert/de-assert the reset
+signal on driver suspend/resume.
+
+In case the no_console_suspend is specified by the user, the registers need
+to be saved on suspend path and restore on resume path. To do this the
+sci_console_save()/sci_console_restore() functions were added. There is no
+need to cache/restore the status or FIFO registers. Only the control
+registers. The registers that will be saved/restored on suspend/resume are
+specified by the struct sci_suspend_regs data structure.

+Subject: smack: recognize ipv4 CIPSO w/o categories
+
+From: Konstantin Andreev <andreev@swemel.ru>
+
+[ Upstream commit a158a937d864d0034fea14913c1f09c6d5f574b8 ]
+
+If SMACK label has CIPSO representation w/o categories, e.g.:
+
+| # cat /smack/cipso2
+| foo 10
+| @ 250/2
+| ...
+
+then SMACK does not recognize such CIPSO in input ipv4 packets
+and substitues '*' label instead. Audit records may look like
+
+| lsm=SMACK fn=smack_socket_sock_rcv_skb action=denied
+| subject="*" object="_" requested=w pid=0 comm="swapper/1" ...
+
+This happens in two steps:
+
+1) security/smack/smackfs.c`smk_set_cipso
+ does not clear NETLBL_SECATTR_MLS_CAT
+ from (struct smack_known *)skp->smk_netlabel.flags
+ on assigning CIPSO w/o categories:
+
+| rcu_assign_pointer(skp->smk_netlabel.attr.mls.cat, ncats.attr.mls.cat);
+| skp->smk_netlabel.attr.mls.lvl = ncats.attr.mls.lvl;
+
+2) security/smack/smack_lsm.c`smack_from_secattr
+ can not match skp->smk_netlabel with input packet's
+ struct netlbl_lsm_secattr *sap
+ because sap->flags have not NETLBL_SECATTR_MLS_CAT (what is correct)
+ but skp->smk_netlabel.flags have (what is incorrect):
+
+| if ((sap->flags & NETLBL_SECATTR_MLS_CAT) == 0) {
+| if ((skp->smk_netlabel.flags &
+| NETLBL_SECATTR_MLS_CAT) == 0)
+| found = 1;
+| break;
+| }
+
+This commit sets/clears NETLBL_SECATTR_MLS_CAT in
+skp->smk_netlabel.flags according to the presense of CIPSO categories.
+The update of smk_netlabel is not atomic, so input packets processing
+still may be incorrect during short time while update proceeds.

+Subject: soc: apple: rtkit: Implement OSLog buffers properly
+
+From: Hector Martin <marcan@marcan.st>
+
+[ Upstream commit a06398687065e0c334dc5fc4d2778b5b87292e43 ]
+
+Apparently nobody can figure out where the old logic came from, but it
+seems like it has never been actually used on any supported firmware to
+this day. OSLog buffers were apparently never requested.
+
+But starting with 13.3, we actually need this implemented properly for
+MTP (and later AOP) to work, so let's actually do that.

+
+From: Janne Grunau <j@jannau.net>
+
+[ Upstream commit 22af2fac88fa5dbc310bfe7d0b66d4de3ac47305 ]
+
+rtkit messages as communication with the DCP firmware for framebuffer
+swaps or input events are time critical so use WQ_HIGHPRI to prevent
+user space CPU load to increase latency.
+With kwin_wayland 6's explicit sync mode user space load was able to
+delay the IOMFB rtkit communication enough to miss vsync for surface
+swaps. Minimal test scenario is constantly resizing a glxgears
+Xwayland window.

+Subject: soc: ti: k3-socinfo: Do not use syscon helper to build regmap
+
+From: Andrew Davis <afd@ti.com>
+
+[ Upstream commit a5caf03188e44388e8c618dcbe5fffad1a249385 ]
+
+The syscon helper device_node_to_regmap() is used to fetch a regmap
+registered to a device node. It also currently creates this regmap
+if the node did not already have a regmap associated with it. This
+should only be used on "syscon" nodes. This driver is not such a
+device and instead uses device_node_to_regmap() on its own node as
+a hacky way to create a regmap for itself.
+
+This will not work going forward and so we should create our regmap
+the normal way by defining our regmap_config, fetching our memory
+resource, then using the normal regmap_init_mmio() function.

+From: Sean Anderson <sean.anderson@linux.dev>
+
+[ Upstream commit 89785306453ce6d949e783f6936821a0b7649ee2 ]
+
+RXEMPTY can cause an IRQ, even though we may not do anything about it
+(such as if we are waiting for more received data). We must still handle
+these IRQs because we can tell they were caused by the device.

+Subject: tcp: bring back NUMA dispersion in inet_ehash_locks_alloc()
+
+From: Eric Dumazet <edumazet@google.com>
+
+[ Upstream commit f8ece40786c9342249aa0a1b55e148ee23b2a746 ]
+
+We have platforms with 6 NUMA nodes and 480 cpus.
+
+inet_ehash_locks_alloc() currently allocates a single 64KB page
+to hold all ehash spinlocks. This adds more pressure on a single node.
+
+Change inet_ehash_locks_alloc() to use vmalloc() to spread
+the spinlocks on all online nodes, driven by NUMA policies.
+
+At boot time, NUMA policy is interleave=all, meaning that
+tcp_hashinfo.ehash_locks gets hash dispersion on all nodes.
+
+Tested:

+Subject: timer_list: Don't use %pK through printk()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Thomas Weißschuh <thomas.weissschuh@linutronix.de>
+
+[ Upstream commit a52067c24ccf6ee4c85acffa0f155e9714f9adce ]
+
+This reverts commit f590308536db ("timer debug: Hide kernel addresses via
+%pK in /proc/timer_list")
+
+The timer list helper SEQ_printf() uses either the real seq_printf() for
+procfs output or vprintk() to print to the kernel log, when invoked from
+SysRq-q. It uses %pK for printing pointers.
+
+In the past %pK was prefered over %p as it would not leak raw pointer
+values into the kernel log. Since commit ad67b74d2469 ("printk: hash
+addresses printed with %p") the regular %p has been improved to avoid this
+issue.
+
+Furthermore, restricted pointers ("%pK") were never meant to be used
+through printk(). They can still unintentionally leak raw pointers or
+acquire sleeping looks in atomic contexts.
+
+Switch to the regular pointer formatting which is safer, easier to reason
+about and sufficient here.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
+
+[ Upstream commit 196a062641fe68d9bfe0ad36b6cd7628c99ad22c ]
+
+Binary printing functions are using printf() type of format, and compiler
+is not happy about them as is:
+
+kernel/trace/trace.c:3292:9: error: function ‘trace_vbprintk’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format]
+kernel/trace/trace_seq.c:182:9: error: function ‘trace_seq_bprintf’ might be a candidate for ‘gnu_printf’ format attribute [-Werror=suggest-attribute=format]
+
+Fix the compilation errors by adding __printf() attribute.
+
+While at it, move existing __printf() attributes from the implementations
+to the declarations. IT also fixes incorrect attribute parameters that are
+used for trace_array_printk().

+
+Doing this allows using registers as retrieved from an mcontext to be
+pushed to a process using PTRACE_SETREGS.
+
+It is not entirely clear to me why CSGSFS was masked. Doing so creates
+issues when using the mcontext as process state in seccomp and simply
+copying the register appears to work perfectly fine for ptrace.

+Subject: vfio/pci: Handle INTx IRQ_NOTCONNECTED
+
+From: Alex Williamson <alex.williamson@redhat.com>
+
+[ Upstream commit 860be250fc32de9cb24154bf21b4e36f40925707 ]
+
+Some systems report INTx as not routed by setting pdev->irq to
+IRQ_NOTCONNECTED, resulting in a -ENOTCONN error when trying to
+setup eventfd signaling. Include this in the set of conditions
+for which the PIN register is virtualized to zero.
+
+Additionally consolidate vfio_pci_get_irq_count() to use this
+virtualized value in reporting INTx support via ioctl and sanity
+checking ioctl paths since pdev->irq is re-used when the device
+is in MSI mode.
+
+The combination of these results in both the config space of the
+device and the ioctl interface behaving as if the device does not
+support INTx.

+==================================================================
+
+When the data race occurs, the function virtqueue_enable_cb_delayed() sets
+event_triggered to false, and virtqueue_disable_cb_split/packed() reads it
+as false due to the race condition. Since event_triggered is an unreliable
+hint used for optimization, this should only cause the driver temporarily
+suggest that the device not send an interrupt notification when the event
+index is used.
+
+Fix this KCSAN reported data-race issue by explicitly tagging the access as
+data_racy.

+Subject: vxlan: Join / leave MC group after remote changes
+
+From: Petr Machata <petrm@nvidia.com>
+
+[ Upstream commit d42d543368343c0449a4e433b5f02e063a86209c ]
+
+When a vxlan netdevice is brought up, if its default remote is a multicast
+address, the device joins the indicated group.
+
+Therefore when the multicast remote address changes, the device should
+leave the current group and subscribe to the new one. Similarly when the
+interface used for endpoint communication is changed in a situation when
+multicast remote is configured. This is currently not done.
+
+Both vxlan_igmp_join() and vxlan_igmp_leave() can however fail. So it is
+possible that with such fix, the netdevice will end up in an inconsistent
+situation where the old group is not joined anymore, but joining the new
+group fails. Should we join the new group first, and leave the old one
+second, we might end up in the opposite situation, where both groups are
+joined. Undoing any of this during rollback is going to be similarly
+problematic.
+
+One solution would be to just forbid the change when the netdevice is up.
+However in vnifilter mode, changing the group address is allowed, and these
+problems are simply ignored (see vxlan_vni_update_group()):
+
+ # ip link add name br up type bridge vlan_filtering 1
+ # ip link add vx1 up master br type vxlan external vnifilter local 192.0.2.1 dev lo dstport 4789
+ # bridge vni add dev vx1 vni 200 group 224.0.0.1
+ # tcpdump -i lo &
+ # bridge vni add dev vx1 vni 200 group 224.0.0.2
+ 18:55:46.523438 IP 0.0.0.0 > 224.0.0.22: igmp v3 report, 1 group record(s)
+ 18:55:46.943447 IP 0.0.0.0 > 224.0.0.22: igmp v3 report, 1 group record(s)
+ # bridge vni
+ dev vni group/remote
+ vx1 200 224.0.0.2
+
+Having two different modes of operation for conceptually the same interface
+is silly, so in this patch, just do what the vnifilter code does and deal
+with the errors by crossing fingers real hard.
+
+The vnifilter code leaves old before joining new, and in case of join /
+leave failures does not roll back the configuration changes that have
+already been applied, but bails out of joining if it could not leave. Do
+the same here: leave before join, apply changes unconditionally and do not
+attempt to join if we couldn't leave.

+When using nvmem, ath9k could potentially be loaded before nvmem, which

+
+If nvmem is not ready in time for ath9k, -EPROBE_DEFER is returned. Pass

+
+From: Johannes Berg <johannes.berg@intel.com>
+
+[ Upstream commit f4995cdc4d02d0abc8e9fcccad5c71ce676c1e3f ]
+
+In the original commit 15fae3410f1d ("mac80211: notify driver on
+mgd TX completion") I evidently made a mistake and placed the
+call in the "associated" if, rather than the "assoc_data". Later
+I noticed the missing call and placed it in commit c042600c17d8
+("wifi: mac80211: adding missing drv_mgd_complete_tx() call"),
+but didn't remove the wrong one. Remove it now.

+
+From: Soeren Moch <smoch@web.de>
+
+[ Upstream commit 3d3e28feca7ac8c6cf2a390dbbe1f97e3feb7f36 ]
+
+Occasionally there is an EPROTO error during firmware download.
+This error is converted to EAGAIN in the download function.
+But nobody tries again and so device probe fails.
+
+Implement download retry to fix this.
+
+This error was observed (and fix tested) on a tbs2910 board [1]
+with an embedded RTL8188EU (0bda:8179) device behind a USB hub.

+[ Upstream commit 9e8243025cc06abc975c876dffda052073207ab3 ]
+
+After the firmware is uploaded, download_firmware_validate() checks some
+bits in REG_MCUFW_CTRL to see if everything went okay. The
+RTL8814AU power on sequence sets bits 13 and 12 to 2, which this

+
+Make download_firmware_validate() ignore bits 13 and 12.

+Subject: x86/bugs: Make spectre user default depend on MITIGATION_SPECTRE_V2
+
+From: Breno Leitao <leitao@debian.org>
+
+[ Upstream commit 98fdaeb296f51ef08e727a7cc72e5b5c864c4f4d ]
+
+Change the default value of spectre v2 in user mode to respect the
+CONFIG_MITIGATION_SPECTRE_V2 config option.
+
+Currently, user mode spectre v2 is set to auto
+(SPECTRE_V2_USER_CMD_AUTO) by default, even if
+CONFIG_MITIGATION_SPECTRE_V2 is disabled.
+
+Set the spectre_v2 value to auto (SPECTRE_V2_USER_CMD_AUTO) if the
+Spectre v2 config (CONFIG_MITIGATION_SPECTRE_V2) is enabled, otherwise
+set the value to none (SPECTRE_V2_USER_CMD_NONE).
+
+Important to say the command line argument "spectre_v2_user" overwrites
+the default value in both cases.
+
+When CONFIG_MITIGATION_SPECTRE_V2 is not set, users have the flexibility
+to opt-in for specific mitigations independently. In this scenario,
+setting spectre_v2= will not enable spectre_v2_user=, and command line
+options spectre_v2_user and spectre_v2 are independent when
+CONFIG_MITIGATION_SPECTRE_V2=n.

+Subject: x86/build: Fix broken copy command in genimage.sh when making

+
+From: Nir Lichtman <nir@lichtman.org>
+
+[ Upstream commit e451630226bd09dc730eedb4e32cab1cc7155ae8 ]
+
+Problem: Currently when running the "make isoimage" command there is an
+error related to wrong parameters passed to the cp command:
+
+ "cp: missing destination file operand after 'arch/x86/boot/isoimage/'"
+
+This is caused because FDINITRDS is an empty array.
+
+Solution: Check if FDINITRDS is empty before executing the "cp" command,
+similar to how it is done in the case of hdimage.

+Subject: x86/kaslr: Reduce KASLR entropy on most x86 systems
+
+From: Balbir Singh <balbirs@nvidia.com>
+
+[ Upstream commit 7ffb791423c7c518269a9aad35039ef824a40adb ]
+
+When CONFIG_PCI_P2PDMA=y (which is basically enabled on all
+large x86 distros), it maps the PFN's via a ZONE_DEVICE
+mapping using devm_memremap_pages(). The mapped virtual
+address range corresponds to the pci_resource_start()
+of the BAR address and size corresponding to the BAR length.
+
+When KASLR is enabled, the direct map range of the kernel is
+reduced to the size of physical memory plus additional padding.
+If the BAR address is beyond this limit, PCI peer to peer DMA
+mappings fail.
+
+Fix this by not shrinking the size of the direct map when
+CONFIG_PCI_P2PDMA=y.
+
+This reduces the total available entropy, but it's better than
+the current work around of having to disable KASLR completely.

+
+From: Philip Redkin <me@rarity.fan>
+
+[ Upstream commit 631ca8909fd5c62b9fda9edda93924311a78a9c4 ]
+
+At least with CONFIG_PHYSICAL_START=0x100000, if there is < 4 MiB of
+contiguous free memory available at this point, the kernel will crash
+and burn because memblock_phys_alloc_range() returns 0 on failure,
+which leads memblock_phys_free() to throw the first 4 MiB of physical
+memory to the wolves.
+
+At a minimum it should fail gracefully with a meaningful diagnostic,
+but in fact everything seems to work fine without the weird reserve
+allocation.

+This message seemed to be given out from __ghes_panic() running in
+NMI context.
+
+The __register_nmi_handler() function which takes the nmi_desc lock
+with irq disabled shouldn't be called from NMI context as this can
+lead to deadlock.
+
+The nmi_shootdown_cpus() function can only be invoked once. After the
+first invocation, all other CPUs should be stuck in the newly added
+crash_nmi_callback() and cannot respond to a second NMI.
+
+Fix it by adding a new emergency NMI handler to the nmi_desc
+structure and provide a new set_emergency_nmi_handler() helper to set
+crash_nmi_callback() in any context. The new emergency handler will
+preempt other handlers in the linked list. That will eliminate the need
+to take any lock and serve the panic in NMI use case.

+Subject: xen: Add support for XenServer 6.1 platform device
+
+From: Frediano Ziglio <frediano.ziglio@cloud.com>
+
+[ Upstream commit 2356f15caefc0cc63d9cc5122641754f76ef9b25 ]
+
+On XenServer on Windows machine a platform device with ID 2 instead of
+1 is used.
+
+This device is mainly identical to device 1 but due to some Windows
+update behaviour it was decided to use a device with a different ID.
+
+This causes compatibility issues with Linux which expects, if Xen
+is detected, to find a Xen platform device (5853:0001) otherwise code
+will crash due to some missing initialization (specifically grant
+tables). Specifically from dmesg
+
+ RIP: 0010:gnttab_expand+0x29/0x210
+ Code: 90 0f 1f 44 00 00 55 31 d2 48 89 e5 41 57 41 56 41 55 41 89 fd

+ RSP: 0000:ffffba34c01fbc88 EFLAGS: 00010086
+ ...
+
+The device 2 is presented by Xapi adding device specification to
+Qemu command line.

+Subject: xenbus: Allow PVH dom0 a non-local xenstore
+
+From: Jason Andryuk <jason.andryuk@amd.com>
+
+[ Upstream commit 90989869baae47ee2aa3bcb6f6eb9fbbe4287958 ]
+
+Make xenbus_init() allow a non-local xenstore for a PVH dom0 - it is
+currently forced to XS_LOCAL. With Hyperlaunch booting dom0 and a
+xenstore stubdom, dom0 can be handled as a regular XS_HVM following the
+late init path.
+
+Ideally we'd drop the use of xen_initial_domain() and just check for the
+event channel instead. However, ARM has a xen,enhanced no-xenstore
+mode, where the event channel and PFN would both be 0. Retain the
+xen_initial_domain() check, and use that for an additional check when
+the event channel is 0.
+
+Check the full 64bit HVM_PARAM_STORE_EVTCHN value to catch the off
+chance that high bits are set for the 32bit event channel.
