+Subject: Bluetooth: MGMT: Fix OOB access in parse_adv_monitor_pattern()
+
+From: Ilia Gavrilov <Ilia.Gavrilov@infotecs.ru>
+
+commit 8d59fba49362c65332395789fd82771f1028d87e upstream.
+
+In the parse_adv_monitor_pattern() function, the value of
+the 'length' variable is currently limited to HCI_MAX_EXT_AD_LENGTH(251).
+The size of the 'value' array in the mgmt_adv_pattern structure is 31.
+If the value of 'pattern[i].length' is set in the user space
+and exceeds 31, the 'patterns[i].value' array can be accessed
+out of bound when copied.
+
+Increasing the size of the 'value' array in
+the 'mgmt_adv_pattern' structure will break the userspace.
+Considering this, and to avoid OOB access revert the limits for 'offset'
+and 'length' back to the value of HCI_MAX_AD_LENGTH.
+
+Found by InfoTeCS on behalf of Linux Verification Center
+(linuxtesting.org) with SVACE.

+Subject: drm/amd/display: Enable mst when it's detected but yet to be initialized
+
+From: Wayne Lin <Wayne.Lin@amd.com>
+
+commit 3c6a743c6961cc2cab453b343bb157d6bbbf8120 upstream.
+
+[Why]
+drm_dp_mst_topology_queue_probe() is used under the assumption that
+mst is already initialized. If we connect system with SST first
+then switch to the mst branch during suspend, we will fail probing
+topology by calling the wrong API since the mst manager is yet to
+be initialized.
+
+[How]
+At dm_resume(), once it's detected as mst branc connected, check if
+the mst is initialized already. If not, call
+dm_helpers_dp_mst_start_top_mgr() instead to initialize mst
+
+V2: Adjust the commit msg a bit

+From: Rong Zhang <i@rong.moe>

+commit 6dd97ceb645c08aca9fc871a3006e47fe699f0ac upstream.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com>
+
+commit 487df8b698345dd5a91346335f05170ed5f29d4e upstream.
+
+The Mesa issue referenced below pointed out a possible deadlock:
+
+[ 1231.611031] Possible interrupt unsafe locking scenario:
+
+[ 1231.611033] CPU0 CPU1
+[ 1231.611034] ---- ----
+[ 1231.611035] lock(&xa->xa_lock#17);
+[ 1231.611038] local_irq_disable();
+[ 1231.611039] lock(&fence->lock);
+[ 1231.611041] lock(&xa->xa_lock#17);
+[ 1231.611044] <Interrupt>
+[ 1231.611045] lock(&fence->lock);
+[ 1231.611047]
+ *** DEADLOCK ***
+
+In this example, CPU0 would be any function accessing job->dependencies
+through the xa_* functions that don't disable interrupts (eg:
+drm_sched_job_add_dependency(), drm_sched_entity_kill_jobs_cb()).
+
+CPU1 is executing drm_sched_entity_kill_jobs_cb() as a fence signalling
+callback so in an interrupt context. It will deadlock when trying to
+grab the xa_lock which is already held by CPU0.
+
+Replacing all xa_* usage by their xa_*_irq counterparts would fix
+this issue, but Christian pointed out another issue: dma_fence_signal
+takes fence.lock and so does dma_fence_add_callback.
+
+ dma_fence_signal() // locks f1.lock
+ -> drm_sched_entity_kill_jobs_cb()
+ -> foreach dependencies
+ -> dma_fence_add_callback() // locks f2.lock
+
+This will deadlock if f1 and f2 share the same spinlock.
+
+To fix both issues, the code iterating on dependencies and re-arming them
+is moved out to drm_sched_entity_kill_jobs_work().

+Subject: iommufd: Don't overflow during division for dirty tracking
+
+From: Jason Gunthorpe <jgg@nvidia.com>
+
+commit cb30dfa75d55eced379a42fd67bd5fb7ec38555e upstream.
+
+If pgshift is 63 then BITS_PER_TYPE(*bitmap->bitmap) * pgsize will overflow
+to 0 and this triggers divide by 0.
+
+In this case the index should just be 0, so reorganize things to divide
+by shift and avoid hitting any overflows.

+
+From: Nathan Chancellor <nathan@kernel.org>
+
+commit 2b81082ad37cc3f28355fb73a6a69b91ff7dbf20 upstream.
+
+Commit 2f13daee2a72 ("lib/crypto/curve25519-hacl64: Disable KASAN with
+clang-17 and older") inadvertently disabled KASAN in curve25519-hacl64.o
+for GCC unconditionally because clang-min-version will always evaluate
+to nothing for GCC. Add a check for CONFIG_CC_IS_CLANG to avoid applying
+the workaround for GCC, which is only needed for clang-17 and older.

+From: Helge Deller <deller@gmx.de>
+
+commit fd9f30d1038ee1624baa17a6ff11effe5f7617cb upstream.

+ lock: terminate_lock.2+0x0/0x1c, .magic: dead4ead, .owner: ifconfig/2420, .owner_cpu: 0
+
+While creating the stack trace, the unwinder uses the stack pointer to guess
+the previous frame to read the previous stack pointer from memory. The crash
+happens, because the unwinder tries to read from unaligned memory and as such
+triggers the unalignment trap handler which then leads to the spinlock
+recursion and finally to a deadlock.
+
+Fix it by checking the alignment before accessing the memory.

+Subject: scsi: ufs: core: Add a quirk to suppress link_startup_again
+
+From: Adrian Hunter <adrian.hunter@intel.com>
+
+commit d34caa89a132cd69efc48361d4772251546fdb88 upstream.
+
+ufshcd_link_startup() has a facility (link_startup_again) to issue
+DME_LINKSTARTUP a 2nd time even though the 1st time was successful.
+
+Some older hardware benefits from that, however the behaviour is
+non-standard, and has been found to cause link startup to be unreliable
+for some Intel Alder Lake based host controllers.
+
+Add UFSHCD_QUIRK_PERFORM_LINK_STARTUP_ONCE to suppress
+link_startup_again, in preparation for setting the quirk for affected
+controllers.

+Subject: scsi: ufs: ufs-pci: Fix S0ix/S3 for Intel controllers
+
+From: Adrian Hunter <adrian.hunter@intel.com>
+
+commit bb44826c3bdbf1fa3957008a04908f45e5666463 upstream.
+
+Intel platforms with UFS, can support Suspend-to-Idle (S0ix) and
+Suspend-to-RAM (S3). For S0ix the link state should be HIBERNATE. For
+S3, state is lost, so the link state must be OFF. Driver policy,
+expressed by spm_lvl, can be 3 (link HIBERNATE, device SLEEP) for S0ix
+but must be changed to 5 (link OFF, device POWEROFF) for S3.
+
+Fix support for S0ix/S3 by switching spm_lvl as needed. During suspend
+->prepare(), if the suspend target state is not Suspend-to-Idle, ensure
+the spm_lvl is at least 5 to ensure that resume will be possible from
+deep sleep states. During suspend ->complete(), restore the spm_lvl to
+its original value that is suitable for S0ix.
+
+This fix is first needed in Intel Alder Lake based controllers.

+Subject: smb: client: fix potential UAF in smb2_close_cached_fid()
+
+From: Henrique Carvalho <henrique.carvalho@suse.com>
+
+commit 734e99623c5b65bf2c03e35978a0b980ebc3c2f8 upstream.
+
+find_or_create_cached_dir() could grab a new reference after kref_put()
+had seen the refcount drop to zero but before cfid_list_lock is acquired
+in smb2_close_cached_fid(), leading to use-after-free.
+
+Switch to kref_put_lock() so cfid_release() is called with
+cfid_list_lock held, closing that gap.
+
+Fixes: ebe98f1447bb ("cifs: enable caching of directories for which a lease is held")

+Subject: smb: client: validate change notify buffer before copy
+
+From: Joshua Rogers <linux@joshua.hu>
+
+commit 4012abe8a78fbb8869634130024266eaef7081fe upstream.
+
+SMB2_change_notify called smb2_validate_iov() but ignored the return
+code, then kmemdup()ed using server provided OutputBufferOffset/Length.
+
+Check the return of smb2_validate_iov() and bail out on error.
+
+Discovered with help from the ZeroPath security tooling.

+Subject: virtio-net: fix received length check in big packets
+
+From: Bui Quang Minh <minhquangbui99@gmail.com>
+
+commit 0c716703965ffc5ef4311b65cb5d84a703784717 upstream.
+
+Since commit 4959aebba8c0 ("virtio-net: use mtu size as buffer length
+for big packets"), when guest gso is off, the allocated size for big
+packets is not MAX_SKB_FRAGS * PAGE_SIZE anymore but depends on
+negotiated MTU. The number of allocated frags for big packets is stored
+in vi->big_packets_num_skbfrags.
+
+Because the host announced buffer length can be malicious (e.g. the host
+vhost_net driver's get_rx_bufs is modified to announce incorrect
+length), we need a check in virtio_net receive path. Currently, the
+check is not adapted to the new change which can lead to NULL page
+pointer dereference in the below while loop when receiving length that
+is larger than the allocated one.
+
+This commit fixes the received length check corresponding to the new
+change.
+
