+Subject: ALSA: usb-audio: Add quirk flag for HEM devices to enable native DSD playback
+
+From: Lukasz Tyl <ltyl@hem-e.com>
+
+commit 122e2cb7e1a30438cc0e8bf70d4279db245d7d5b upstream.
+
+This commit adds new DEVICE_FLG with QUIRK_FLAG_DSD_RAW and Vendor Id for
+HEM devices which supports native DSD. Prior to this change Linux kernel
+was not enabling native DSD playback for HEM devices, and as a result,
+DSD audio was being converted to PCM "on the fly". HEM devices,
+when connected to the system, would only play audio in PCM format,
+even if the source material was in DSD format. With the addition of new
+VENDOR_FLG in the quircks.c file, the devices are now correctly
+recognized, and raw DSD data is transmitted to the device,
+allowing for native DSD playback.

+Subject: ALSA: usb-audio: Fix broken resume due to UAC3 power state
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 8ba61c9f6c9bdfbf9d197b0282641d24ae909778 upstream.
+
+As reported in the bugzilla below, the PM resume of a UAC3 device may
+fail due to the incomplete power state change, stuck at D1.  The
+reason is that the driver expects the full D0 power state change only
+at hw_params, while the normal PCM resume procedure doesn't call
+hw_params.
+
+For fixing the bug, we add the same power state update to D0 at the
+prepare callback, which is certainly called by the resume procedure.
+
+Note that, with this change, the power state change in the hw_params
+becomes almost redundant, since snd_usb_hw_params() doesn't touch the
+parameters (at least it tires so).  But dropping it is still a bit
+risky (e.g. we have the media-driver binding), so I leave the D0 power
+state change in snd_usb_hw_params() as is for now.
+

+Subject: btrfs: can_nocow_file_extent should pass down args->strict from callers
+
+From: Chris Mason <clm@fb.com>
+
+commit deccae40e4b30f98837e44225194d80c8baf2233 upstream.
+
+Commit 619104ba453ad0 ("btrfs: move common NOCOW checks against a file
+extent into a helper") changed our call to btrfs_cross_ref_exist() to
+always pass false for the 'strict' parameter.  We're passing this down
+through the stack so that we can do a full check for cross references
+during swapfile activation.
+
+With strict always false, this test fails:
+
+  btrfs subvol create swappy
+  chattr +C swappy
+  fallocate -l1G swappy/swapfile
+  chmod 600 swappy/swapfile
+  mkswap swappy/swapfile
+
+  btrfs subvol snap swappy swapsnap
+  btrfs subvol del -C swapsnap
+
+  btrfs fi sync /
+  sync;sync;sync
+
+  swapon swappy/swapfile
+
+The fix is to just use args->strict, and everyone except swapfile
+activation is passing false.

+
+[CAUSE]
+Since the introduction of global roots, we handle
+csum/extent/free-space-tree roots as global roots, even if no
+extent-tree-v2 feature is enabled.
+
+So for regular csum/extent/fst roots, we load them into
+fs_info::global_root_tree rb tree.
+
+And we should not expect any conflicts in that rb tree, thus we have an
+ASSERT() inside btrfs_global_root_insert().
+
+But rescue=usebackuproot can break the assumption, as we will try to
+load those trees again and again as long as we have bad roots and have
+backup roots slot remaining.
+
+So in that case we can have conflicting roots in the rb tree, and
+triggering the ASSERT() crash.
+
+[FIX]
+We can safely remove that ASSERT(), as the caller will properly put the
+offending root.
+
+To make further debugging easier, also add two explicit error messages:
+
+- Error message for conflicting global roots
+- Error message when using backup roots slot

+From: Christoph Hellwig <hch@lst.de>
+
+commit 7833b865953c8e62abc76a3261c04132b2fb69de upstream.
+
+can_nocow_extent can reduce the len passed in, which needs to be
+propagated to btrfs_dio_iomap_begin so that iomap does not submit
+more data then is mapped.
+
+This problems exists since the btrfs_get_blocks_direct helper was added
+in commit c5794e51784a ("btrfs: Factor out write portion of
+btrfs_get_blocks_direct"), but the ordered_extent splitting added in
+commit b73a6fd1b1ef ("btrfs: split partial dio bios before submit")
+added a WARN_ON that made a syzkaller test fail.

+
+From: Mike Snitzer <snitzer@kernel.org>
+
+commit 722d90822321497e2837cfc9000202e256e6b32f upstream.
+
+issue_discard() passes GFP_NOWAIT to __blkdev_issue_discard() despite
+its code assuming bio_alloc() always succeeds.
+
+Commit 3dba53a958a75 ("dm thin: use __blkdev_issue_discard for async
+discard support") clearly shows where things went bad:
+
+Before commit 3dba53a958a75, dm-thin.c's open-coded
+__blkdev_issue_discard_async() properly handled using GFP_NOWAIT.
+Unfortunately __blkdev_issue_discard() doesn't and it was missed
+during review.

+Subject: drm/amd: Make sure image is written to trigger VBIOS image update flow
+
+From: Mario Limonciello <mario.limonciello@amd.com>
+
+commit 3eb1a3a04056ba3df3205e169b8acc9da0c65a94 upstream.
+
+The VBIOS image update flow requires userspace to:
+1) Write the image to `psp_vbflash`
+2) Read `psp_vbflash`
+3) Poll `psp_vbflash_status` to check for completion
+
+If userspace reads `psp_vbflash` before writing an image, it's
+possible that it causes problems that can put the dGPU into an invalid
+state.
+
+Explicitly check that an image has been written before letting a read
+succeed.

+Subject: drm/amd/pm: workaround for compute workload type on some skus
+
+From: Kenneth Feng <kenneth.feng@amd.com>
+
+commit 7ca302d488f80cf4529620acc1c545f9022d8bb8 upstream.
+
+On smu 13.0.0, the compute workload type cannot be set on all the skus
+due to some other problems. This workaround is to make sure compute workload type
+can also run on some specific skus.
+
+v2: keep the variable consistent

+
+commit cac9e4418f4cbd548ccb065b3adcafe073f7f7d2 upstream.
+
+If the application sets ->msg_control and we have to later retry this
+command, or if it got queued with IOSQE_ASYNC to begin with, then we
+need to retain the original msg_control value. This is due to the net
+stack overwriting this field with an in-kernel pointer, to copy it
+in. Hitting that path for the second time will now fail the copy from
+user, as it's attempting to copy from a non-user address.

+Subject: kexec: support purgatories with .text.hot sections
+
+From: Ricardo Ribalda <ribalda@chromium.org>
+
+commit 8652d44f466ad5772e7d1756e9457046189b0dfc upstream.
+
+Patch series "kexec: Fix kexec_file_load for llvm16 with PGO", v7.
+
+When upreving llvm I realised that kexec stopped working on my test
+platform.
+
+The reason seems to be that due to PGO there are multiple .text sections
+on the purgatory, and kexec does not supports that.
+
+
+This patch (of 4):
+
+Clang16 links the purgatory text in two sections when PGO is in use:
+
+  [ 1] .text             PROGBITS         0000000000000000  00000040
+       00000000000011a1  0000000000000000  AX       0     0     16
+  [ 2] .rela.text        RELA             0000000000000000  00003498
+       0000000000000648  0000000000000018   I      24     1     8
+  ...
+  [17] .text.hot.        PROGBITS         0000000000000000  00003220
+       000000000000020b  0000000000000000  AX       0     0     1
+  [18] .rela.text.hot.   RELA             0000000000000000  00004428
+       0000000000000078  0000000000000018   I      24    17     8
+
+And both of them have their range [sh_addr ... sh_addr+sh_size] on the
+area pointed by `e_entry`.
+
+This causes that image->start is calculated twice, once for .text and
+another time for .text.hot. The second calculation leaves image->start
+in a random location.
+
+Because of this, the system crashes immediately after:

+
+commit 30134b7c47bd28fdb4db4d12aef824e0579cfee4 upstream.
+
+Fix a possible memory leak in __stmmac_open when stmmac_init_phy fails.
+It's also needed to free everything allocated by stmmac_setup_dma_desc
+and not just the dma_conf struct.
+
+Drop free_dma_desc_resources from __stmmac_open and correctly call
+free_dma_desc_resources on each user of __stmmac_open on error.

+Subject: nilfs2: fix incomplete buffer cleanup in nilfs_btnode_abort_change_key()
+
+From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
+
+commit 2f012f2baca140c488e43d27a374029c1e59098d upstream.
+
+A syzbot fault injection test reported that nilfs_btnode_create_block, a
+helper function that allocates a new node block for b-trees, causes a
+kernel BUG for disk images where the file system block size is smaller
+than the page size.
+
+This was due to unexpected flags on the newly allocated buffer head, and
+it turned out to be because the buffer flags were not cleared by
+nilfs_btnode_abort_change_key() after an error occurred during a b-tree
+update operation and the buffer was later reused in that state.
+
+Fix this issue by using nilfs_btnode_delete() to abandon the unused
+preallocated buffer in nilfs_btnode_abort_change_key().

+Subject: nilfs2: fix possible out-of-bounds segment allocation in resize ioctl
+
+From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
+
+commit fee5eaecca86afa544355569b831c1f90f334b85 upstream.
+
+Syzbot reports that in its stress test for resize ioctl, the log writing
+function nilfs_segctor_do_construct hits a WARN_ON in
+nilfs_segctor_truncate_segments().
+
+It turned out that there is a problem with the current implementation of
+the resize ioctl, which changes the writable range on the device (the
+range of allocatable segments) at the end of the resize process.
+
+This order is necessary for file system expansion to avoid corrupting the
+superblock at trailing edge.  However, in the case of a file system
+shrink, if log writes occur after truncating out-of-bounds trailing
+segments and before the resize is complete, segments may be allocated from
+the truncated space.
+
+The userspace resize tool was fine as it limits the range of allocatable
+segments before performing the resize, but it can run into this issue if
+the resize ioctl is called alone.
+
+Fix this issue by changing nilfs_sufile_resize() to update the range of
+allocatable segments immediately after successful truncation of segment
+space in case of file system shrink.

+Subject: nilfs2: reject devices with insufficient block count
+
+From: Ryusuke Konishi <konishi.ryusuke@gmail.com>
+
+commit 92c5d1b860e9581d64baca76779576c0ab0d943d upstream.
+
+The current sanity check for nilfs2 geometry information lacks checks for
+the number of segments stored in superblocks, so even for device images
+that have been destructively truncated or have an unusually high number of
+segments, the mount operation may succeed.
+
+This causes out-of-bounds block I/O on file system block reads or log
+writes to the segments, the latter in particular causing
+"a_ops->writepages" to repeatedly fail, resulting in sync_inodes_sb() to
+hang.
+
+Fix this issue by checking the number of segments stored in the superblock
+and avoiding mounting devices that can cause out-of-bounds accesses.  To
+eliminate the possibility of overflow when calculating the number of
+blocks required for the device from the number of segments, this also adds
+a helper function to calculate the upper bound on the number of segments
+and inserts a check using it.

+Subject: nouveau: fix client work fence deletion race
+
+From: Dave Airlie <airlied@redhat.com>
+
+commit c8a5d5ea3ba6a18958f8d76430e4cd68eea33943 upstream.
+
+This seems to have existed for ever but is now more apparant after
+commit 9bff18d13473 ("drm/ttm: use per BO cleanup workers")
+
+My analysis: two threads are running, one in the irq signalling the
+fence, in dma_fence_signal_timestamp_locked, it has done the
+DMA_FENCE_FLAG_SIGNALLED_BIT setting, but hasn't yet reached the
+callbacks.
+
+The second thread in nouveau_cli_work_ready, where it sees the fence is
+signalled, so then puts the fence, cleanups the object and frees the
+work item, which contains the callback.
+
+Thread one goes again and tries to call the callback and causes the
+use-after-free.
+
+Proposed fix: lock the fence signalled check in nouveau_cli_work_ready,
+so either the callbacks are done or the memory is freed.

+
+When changing a file size with fallocate() the new size isn't being

+commit 50d927880e0f90d5cb25e897e9d03e5edacc79a8 upstream.
+
+It's trivial to trigger a use-after-free bug in the ocfs2 quotas code using
+fstest generic/452.  After a read-only remount, quotas are suspended and
+ocfs2_mem_dqinfo is freed through ->ocfs2_local_free_info().  When unmounting
+the filesystem, an UAF access to the oinfo will eventually cause a crash.

+Subject: RDMA/uverbs: Restrict usage of privileged QKEYs
+
+From: Edward Srouji <edwards@nvidia.com>
+
+commit 0cadb4db79e1d9eea66711c4031e435c2191907e upstream.
+
+According to the IB specification rel-1.6, section 3.5.3:
+"QKEYs with the most significant bit set are considered controlled
+QKEYs, and a HCA does not allow a consumer to arbitrarily specify a
+controlled QKEY."
+
+Thus, block non-privileged users from setting such a QKEY.

+
+commit 996c3117dae4c02b38a3cb68e5c2aec9d907ec15 upstream.
+
+The locking was changed recently so now the caller holds the wiphy_lock()
+lock.  Taking the lock inside the reg_wdev_chan_valid() function will
+lead to a deadlock.

+If profile-guided optimization is enabled, the purgatory ends up with
+multiple .text sections.  This is not supported by kexec and crashes the
+system.

+Subject: zswap: do not shrink if cgroup may not zswap
+
+From: Nhat Pham <nphamcs@gmail.com>
+
+commit 0bdf0efa180a9cb1361cbded4e2260a49306ac89 upstream.
+
+Before storing a page, zswap first checks if the number of stored pages
+exceeds the limit specified by memory.zswap.max, for each cgroup in the
+hierarchy.  If this limit is reached or exceeded, then zswap shrinking is
+triggered and short-circuits the store attempt.
+
+However, since the zswap's LRU is not memcg-aware, this can create the
+following pathological behavior: the cgroup whose zswap limit is 0 will
+evict pages from other cgroups continually, without lowering its own zswap
+usage.  This means the shrinking will continue until the need for swap
+ceases or the pool becomes empty.
+
+As a result of this, we observe a disproportionate amount of zswap
+writeback and a perpetually small zswap pool in our experiments, even
+though the pool limit is never hit.
+
+More generally, a cgroup might unnecessarily evict pages from other
+cgroups before we drive the memcg back below its limit.
+
+This patch fixes the issue by rejecting zswap store attempt without
+shrinking the pool when obj_cgroup_may_zswap() returns false.
