+Subject: accel/ivpu: Reject firmware log with size smaller than header
+
+From: Jhonraushan <raushan.jhon@gmail.com>
+
+commit ddb44baed257560f192b145ed36cf8c0a412de47 upstream.
+
+fw_log_from_bo() validates the tracing buffer header_size and that the
+log fits within the BO, but never checks that log->size is at least
+log->header_size. fw_log_print_buffer() then computes:
+
+  u32 data_size = log->size - log->header_size;
+
+which underflows to a near-U32_MAX value when firmware reports a log whose
+size is smaller than its header. That huge data_size defeats the
+log_start/log_end bounds clamps added by commit dd1311bcf0e6 ("accel/ivpu:
+Add bounds checks for firmware log indices"), so fw_log_print_lines() reads
+far past the small real data region of the BO. A size of 0 also makes
+fw_log_from_bo() advance the offset by 0, causing the callers to loop
+forever on the same header.
+
+Reject logs whose size is smaller than the header (which also rejects
+size == 0).

+Subject: block: fix race in blk_time_get_ns() returning 0
+
+From: Mike Waychison <mike@waychison.com>
+
+commit 691b052139c94ee6640ac39e0b764dd3867897c0 upstream.
+
+blk_time_get_ns() populates the per-plug cached timestamp and then
+returns it by re-reading the field:
+
+       if (!plug->cur_ktime) {
+               plug->cur_ktime = ktime_get_ns();
+               current->flags |= PF_BLOCK_TS;
+       }
+       return plug->cur_ktime;
+
+This is problematic when the compiler emits the final
+"return plug->cur_ktime" as a reload from memory, after PF_BLOCK_TS has
+already been set.
+
+Since the cached timestamp is now invalidated from finish_task_switch()
+(fad156c2af22 "block: invalidate cached plug timestamp after task
+switch"), a task preempted between setting PF_BLOCK_TS and that reload
+has plug->cur_ktime zeroed by blk_plug_invalidate_ts() when it is
+scheduled back in.  The reload then returns 0.
+
+A 0 handed back here is stored as a start timestamp -- e.g.
+blk_account_io_start() writes it to rq->start_time_ns -- and later
+subtracted from "now".  blk_account_io_done() then adds (now - 0), i.e.
+roughly the system uptime, to the per-group nsecs[] counters.  On an
+otherwise idle, healthy device this appears as sudden ~uptime-sized jumps
+in the diskstats time fields (write_ticks/discard_ticks/time_in_queue).
+
+The solution is to be explicit in our reads and writes to this field
+that is preemption volatile.  We also add a barrier() to ensure that any
+setting of PF_BLOCK_TS is ordered to happen after the cur_ktime update.
+
+This issue was discovered using AI-assisted kprobes looking for paths
+that were leaking zeroed timestamps in a live system, based on the
+observation that we were sometimes seeing uptime-sized jumps in kernel
+exported counters. This was flagged by NodeDiskIOSaturation
+prometheus alerts that started firing on all hosts post 7.1.3 kernel
+upgrade, due to node-exporter now exporting a nonsensical
+node_disk_io_time_weighted_seconds_total.

+Subject: bpf: Add missing access_ok call to copy_user_syms
+
+From: Jiri Olsa <jolsa@kernel.org>
+
+commit d5dc200c3a3f217de072af269dd90adddf90e48d upstream.
+
+As reported by sashiko we use __get_user without prior access_ok call on the
+user space pointer. Adding the missing call for the whole pointer array.
+
+Plus removing the err check in the error path, because it's not needed and
+also we can return -ENOMEM directly from the first kvmalloc_array fail path.

+Subject: bpf,fork: wipe ->bpf_storage before bailouts that access it
+
+From: Jann Horn <jannh@google.com>
+
+commit 9b51a6155d14389876916726430da30eabb1d4ed upstream.
+
+Currently, copy_process() can bail out to free_task() before p->bpf_storage
+has been initialized, with this call graph (shown here for the
+!CONFIG_MEMCG case):
+
+copy_process
+  dup_task_struct
+    arch_dup_task_struct
+      [copies the entire task_struct, including ->bpf_storage member]
+  [RLIMIT_NPROC check fails]
+  delayed_free_task
+    free_task
+      bpf_task_storage_free
+        rcu_dereference(task->bpf_storage)
+        bpf_local_storage_destroy
+
+In this case, the nascent task's ->bpf_storage member that
+bpf_local_storage_destroy() operates on is a plain copy of the parent's
+->bpf_storage pointer, not a real initialized pointer.
+This leads to badness (kernel hangs, UAF).
+
+This is reachable as long as the process calling fork() has been inserted
+into a task storage map.

+Subject: can: bcm: add missing rcu list annotations and operations
+
+From: Oliver Hartkopp <socketcan@hartkopp.net>
+
+commit 7b2c3eabc4dafc062a25e10711154f2107526a78 upstream.
+
+sashiko-bot remarked the missing use of list_add_rcu() in
+bcm_[rx|tx]_setup() to have a proper initialized bcm_op structure
+when bcm_proc_show() traverses the bcm_op's under rcu_read_lock().
+
+To cover all initial settings of the bcm_op's the list_add_rcu() calls
+are moved to the end of the setup code.
+
+While at it, also fix the mirroring removal side: bcm_release() called
+bcm_remove_op() - which frees the op via call_rcu() - on ops that were
+still linked in bo->tx_ops/bo->rx_ops, without list_del_rcu() first.
+Unlink each op with list_del_rcu() before handing it to bcm_remove_op(),
+matching the existing pattern in bcm_delete_tx_op()/bcm_delete_rx_op().

+Subject: can: bcm: defer rx_op deallocation to workqueue to fix thrtimer UAF
+
+From: Lee Jones <lee@kernel.org>
+
+commit 68973f9db76144825e4f35dfdc80fb8279eb2d57 upstream.
+
+Commit f1b4e32aca08 ("can: bcm: use call_rcu() instead of costly
+synchronize_rcu()") replaced synchronize_rcu() in bcm_delete_rx_op()
+with call_rcu() and introduced the RX_NO_AUTOTIMER flag.
+
+However, this flag check was omitted for thrtimer in the packet rx
+fast-path. During BCM RX operation teardown, a concurrent RCU reader
+(bcm_rx_handler) can race and re-arm thrtimer via
+bcm_rx_update_and_send() after call_rcu() has been scheduled.  Once
+the RCU grace period elapses, bcm_op is freed.  The subsequently
+firing thrtimer then dereferences the deallocated op, causing a UAF.
+
+Adding flag checks to the rx fast-path (bcm_rx_update_and_send) does not
+fully close the TOCTOU race and introduces latency for every CAN frame.
+Conversely, calling hrtimer_cancel() directly inside the RCU callback
+(softirq context) is fatal as hrtimer_cancel() can sleep, triggering
+a "scheduling while atomic" panic.
+
+Resolve this by deferring the timer cancellation and memory free to a
+dedicated unbound workqueue (bcm_wq).  The RCU callback now queues a
+work item to bcm_wq, which safely cancels both timers and deallocates
+memory in sleepable process context.  A dedicated workqueue is used to
+prevent system-wide WQ saturation and is cleanly flushed/destroyed
+on module unload to avoid rmmod page faults.
+
+Since the deferred work can now outlive the calling context by an
+unbounded amount, also take a reference on op->sk when it is assigned
+and drop it only once the deferred work has cancelled both timers, so a
+socket can no longer be freed out from under a still-armed timer whose
+callback (bcm_send_to_user()) dereferences op->sk.

+Subject: can: bcm: fix lockless bound/ifindex race and silent RX_SETUP failure
+
+From: Oliver Hartkopp <socketcan@hartkopp.net>
+
+commit d9b091d9d22fee81ec53fb55d2032951993ceadb upstream.
+
+bcm_sendmsg() reads bo->ifindex and checks bo->bound before taking
+lock_sock(), while bcm_notify(), bcm_connect() and bcm_release() all
+mutate both fields under that same lock. Because the lockless reads
+and the locked writes are unordered with respect to each other, a
+racing bcm_notify() (device unregister) or bcm_connect() (concurrent
+bind on another thread sharing the socket) can make bcm_sendmsg()
+observe an inconsistent combination, e.g. a stale bound=1 together
+with the now-cleared ifindex=0, silently turning a socket bound to a
+specific CAN interface into one that also matches "any" interface.
+
+Keep the lockless bo->bound check purely as a fast-path reject, and
+move the ifindex read (and a bo->bound re-check) into the locked
+section, where every writer already serializes. This removes the
+possibility of observing the two fields torn against each other,
+rather than trying to fix it with more READ_ONCE()/WRITE_ONCE() pairs
+on two independently updated fields. Annotate the now-purely-lockless
+bo->bound accesses consistently across all its write sites.
+
+Also fix bcm_rx_setup() silently returning success when the target
+device disappears concurrently instead of reporting -ENODEV, so a
+broken RX op is no longer left registered as if it had succeeded.

+Subject: can: esd_usb: kill anchored URBs before freeing netdevs
+
+From: Fan Wu <fanwu01@zju.edu.cn>
+
+commit c43122fef328a70045fe7621c06de6b2b8e19264 upstream.
+
+esd_usb_disconnect() frees each CAN netdev with free_candev() inside
+its per-netdev loop and only calls unlink_all_urbs(dev) afterwards.
+The per-netdev private data (struct esd_usb_net_priv) is embedded in
+the net_device allocation returned by alloc_candev(), so once
+free_candev() has run, dev->nets[i] points to freed memory.
+unlink_all_urbs() then dereferences the freed dev->nets[i] to kill the
+per-netdev TX anchor (usb_kill_anchored_urbs(&priv->tx_submitted)),
+clear active_tx_jobs, and reset priv->tx_contexts[].
+
+Reorder the teardown so the anchored URBs are killed before the netdevs
+are freed, matching other CAN/USB drivers in the same directory such as
+ems_usb, usb_8dev and mcba_usb, which unregister, then unlink, then
+free: unregister the netdevs first (which stops their TX queues), call
+unlink_all_urbs(dev) once, then free the netdevs.
+
+This issue was found by an in-house static analysis tool.

+Subject: can: isotp: use unconditional synchronize_rcu() in isotp_release()
+
+From: Oliver Hartkopp <socketcan@hartkopp.net>
+
+commit 9b1a02e0d980ac6b0e36a90378f847062f81d7e4 upstream.
+
+isotp_notify() unregisters the (RCU) CAN filters via can_rx_unregister()
+and clears so->bound without waiting for a grace period. isotp_release()
+uses so->bound to decide whether it needs to call synchronize_rcu()
+before cancelling so->rxtimer, so when NETDEV_UNREGISTER runs first it
+skips that synchronize_rcu() and can cancel the timer while an
+in-flight isotp_rcv() is still executing and about to re-arm it via
+isotp_send_fc(), leading to a use-after-free timer callback on the
+freed socket.
+
+sakisho-bot remarked a problem with rtnl_lock held in isotp_notify(),
+therefore make isotp_release() always call synchronize_rcu() before
+cancelling the timers, regardless of so->bound. This still closes the
+original race (isotp_notify() clearing so->bound without waiting for
+in-flight isotp_rcv() callers before isotp_release() cancels the RX
+timer) without adding any RCU wait to the netdevice notifier path.

+
+From: Mikulas Patocka <mpatocka@redhat.com>
+
+commit 422f1d4f141eaa3a6e4199ceec86cc6b9bf26570 upstream.
+
+block_to_sector converts a block number to a sector number and adds
+c->start to the result. It is inappropriate to use this function for
+converting the number of blocks to a number to sectors because c->start
+would be incorrectly added to the result.
+
+Luckily, the only target that uses dm_bufio_issue_discard is dm-ebs,
+which sets c->start to 0, so this bug is latent.

+Subject: dm era: fix out-of-bounds memory access for non-zero start sector
+
+From: Samuel Moelius <sam.moelius@trailofbits.com>
+
+commit a868196f03c2b19418ae3d2b69e195d668a271e5 upstream.
+
+dm-era tracks writes in target-relative blocks, but era_map() calculates
+the writeset block before applying the target offset.  Tables with a
+non-zero start sector can therefore pass an absolute mapped-device block
+to metadata_current_marked().
+
+If the absolute block is beyond the current writeset size,
+writeset_marked() tests past the end of the in-core bitset.  KASAN reports
+this as a vmalloc-out-of-bounds access.
+
+Apply the target offset before calculating the era block so writeset
+lookups use the target-relative block number.

+
+If dm_integrity_check_limits fails, the code would exit with
+DM_MAPIO_KILL. However, the range would be already locked at this point,
+and it wouldn't be unlocked, resulting in a deadlock. Let's move the

+commit 76c6f845dc0c614304a6e6ee619b552f97cf24b3 upstream.
+
+sizeof(tt->version) is 12 bytes, but the code writes 16 bytes into the
+output buffer - info->vers->version[0], info->vers->version[1],
+info->vers->version[2] and info->vers->next. This can cause buffer
+overflow.
+
+Fix this buffer overflow by replacing "sizeof(tt->version)" with
+"sizeof(struct dm_target_versions)".

+
+From: Benjamin Marzinski <bmarzins@redhat.com>
+
+commit 9743132a41f4d9d0e54c5f2adcb821b04796bab1 upstream.
+
+Commit c20e36b7631d ("dm log: fix out-of-bounds write due to
+region_count overflow") made sure that region_count could fit in an
+unsigned int. But the bitmap memory isn't allocated based on
+region_count. It uses bitset_size (a size_t variable). The first step of
+calculating bitset_size is to set it to region_count, rounded up to a
+multiple of BITS_PER_LONG. If region_size is less than BITS_PER_LONG
+smaller than UINT_MAX, it will get rounded up to 2^32. On a 32bit
+architecture, this will make bitset_size wrap around to 0 and fail,
+despite region_count being valid.
+
+Since bitset_size gets divided by 8, it can hold any valid region_count.
+It just needs a special case to handle the rollover. If it is 0, the
+value rolled over, and bitset size should be set to the number of bytes
+needed to hold 2^32 bits.

+
+From: Ming-Hung Tsai <mtsai@redhat.com>
+
+commit 5bcd4d3058ebaf46ad2e163829d87dd4870c7a45 upstream.
+
+__reserve_metadata_snap() and __release_metadata_snap() modify the
+superblock's held_root directly in the block_manager's buffer. If the
+subsequent metadata commit fails, the held_root gets flushed to disk
+through the abort_transaction path, resulting in inconsistent metadata.
+
+Reproducer 1: __reserve_metadata_snap()
+
+1. Create a 2 MiB metadata device and make the region after the 14th
+   block inaccessible, to trigger metadata commit failure in the
+   subsequent reserve_metadata_snap operation. The 14th block will be
+   the shadow destination for the index block.
+
+dmsetup create tmeta --table "0 112 linear /dev/sdc 0
+112 3984 error"
+
+2. Create a 16 MiB thin-pool
+
+dmsetup create tdata --table "0 32768 zero"
+dd if=/dev/zero of=/dev/mapper/tmeta bs=4k count=1
+dmsetup create tpool --table "0 32768 thin-pool /dev/mapper/tmeta \
+/dev/mapper/tdata 128 0 1 skip_block_zeroing"
+
+3. Take a metadata snapshot to trigger metadata commit failure and
+   transaction abort. However, the held_root is written to disk,
+   breaking metadata consistency.
+
+dmsetup message tpool 0 "reserve_metadata_snap"
+
+thin_check v1.2.2 result:
+

+3. Reserve then release the metadata snapshot, to trigger metadata
+   commit failure and transaction abort. The held_root gets removed
+   from the on-disk superblock, causing inconsistent metadata.

+Bad reference count for metadata block 7.  Expected 1, but space map contains 2.
+1 metadata blocks have leaked.
+
+Fix by deferring the held_root update to commit time.
+
+Additionally, move the existing-snapshot check in __reserve_metadata_snap
+before the shadow operation to avoid unnecessary work. In
+__release_metadata_snap, clear pmd->held_root before btree deletion so
+partial failure leaks blocks rather than leaving a stale reference, and
+unlock the snapshot block before decrementing its refcount.

+From: Genjian Zhang <zhanggenjian@kylinos.cn>
+
+commit 4b22d0801fadfcae2e106e6ba32e49439c7c7ebf upstream.
+
+__reserve_metadata_snap() increments THIN_SUPERBLOCK_LOCATION in the
+metadata space map before shadowing it. When dm_tm_shadow_block()
+fails, a reference is leaked in the metadata space map.
+
+Fix by adding the missing dm_sm_dec_block().

+Subject: dm-verity: avoid double increment of &use_bh_wq_enabled
+
+From: Mikulas Patocka <mpatocka@redhat.com>
+
+commit 72e9ec2fe32b00994f41719cf77423fca67d48b2 upstream.
+
+verity_parse_opt_args is called twice, first with the only_modifier_opts,
+first with only_modifier_opts == true and then with only_modifier_opts ==
+false. Thus, the static branch &use_bh_wq_enabled was incremented twice
+and the destructor verity_dtr would only decrement it once.
+
+Fix tihs bug by only incrementing it on the first call, on the second
+call, when v->use_bh_wq is true, do nothing.

+From: Mikulas Patocka <mpatocka@redhat.com>
+
+commit 366665416f20527ff7cad548a32d1ddf23195740 upstream.
+
+If dm_resume fails, the kernel attempts to free table with
+dm_table_destroy, but the table was already instantiated with
+dm_swap_table. This commit skips the call to dm_table_destroy in this
+case.

+
+From: Frank Li <Frank.Li@nxp.com>
+
+commit 8ffba0171c6bbce5f093c6dba5a02c0805b31203 upstream.
+
+The DONE_INT_MASK and ABORT_INT_MASK registers are shared by all DMA
+channels, and modifying them requires a read-modify-write sequence.
+Because this operation is not atomic, concurrent calls to
+dw_edma_v0_core_start() can introduce race conditions if two channels
+update these registers simultaneously.
+
+Add a spinlock to serialize access to these registers and prevent race
+conditions.

+Subject: dmaengine: tegra: Fix burst size calculation
+
+From: Kartik Rajput <kkartik@nvidia.com>
+
+commit 4651df83b6c796daead3447e8fd874322918ee4f upstream.
+
+Currently, the Tegra GPC DMA hardware requires the transfer length to
+be a multiple of the max burst size configured for the channel. When a
+client requests a transfer where the length is not evenly divisible by
+the configured max burst size, the DMA hangs with partial burst at
+the end.
+
+Fix this by reducing the burst size to the largest power-of-2 value
+that evenly divides the transfer length. For example, a 40-byte
+transfer with a 16-byte max burst will now use an 8-byte burst
+(40 / 8 = 5 complete bursts) instead of causing a hang.
+
+This issue was observed with the PL011 UART driver where TX DMA
+transfers of arbitrary lengths were stuck.

+Subject: fpga: dfl: add bounds check in dfh_get_param_size()
+
+From: Sebastian Alba Vives <sebasjosue84@gmail.com>
+
+commit 9e8bc49f91f3f81d957c4f1c1f09fe94e2f88f6a upstream.
+
+dfh_get_param_size() can return a parameter size larger than the feature
+region because the loop bounds check is evaluated before incrementing
+size. If the EOP (End of Parameters) bit is set in the same iteration,
+the inflated size is returned without re-validation against max.
+
+This can cause create_feature_instance() to call memcpy_fromio() with a
+size exceeding the ioremap'd region when a malicious FPGA device provides
+crafted DFHv1 parameter headers.
+
+Add a bounds check after the size increment to ensure the accumulated
+size never exceeds the feature boundary.

+Subject: fpga: microchip-spi: fix zero header_size OOB read in mpf_ops_parse_header()
+
+From: Sebastian Alba Vives <sebasjosue84@gmail.com>
+
+commit 43a1974da6bc7ce8f4d1dc1d03d56997428c29c3 upstream.
+
+mpf_ops_parse_header() reads header_size from the bitstream at
+MPF_HEADER_SIZE_OFFSET (24). When header_size is zero, the expression
+*(buf + header_size - 1) reads one byte before the buffer start.
+
+Since initial_header_size is set to 71 in mpf_ops, the fpga-mgr core
+guarantees the buffer is large enough to reach MPF_HEADER_SIZE_OFFSET.
+The only real gap is the zero header_size case, which cannot be
+resolved by providing a larger buffer, so return -EINVAL.

+From: Roman Vivchar <rva333@protonmail.com>
+
+commit deb35336b5bfed5db9231b5348bc1514db930797 upstream.
+
+MediaTek mt65xx family SoCs have no auto restart, however, they still
+support the WRRD mode in the hardware. Because auto_restart is set to 0,
+the WRRD mode will be never enabled, leading to read errors.
+
+Fix this by removing auto_restart check from the WRRD enable path.

+
+If devm_platform_get_and_ioremap_resource() returns an error,
+mlxbf_i2c_init_resource() frees tmp_res before reading tmp_res->io to
+get the error code. This results in a use-after-free.
+
+Save the error code before freeing tmp_res.

+Subject: ice: fix ice_init_link() error return preventing probe
+
+From: Paul Greenwalt <paul.greenwalt@intel.com>
+
+commit eb509638686b0f8a98a0dd9c809f6a8db4d73a45 upstream.
+
+ice_init_link() can return an error status from ice_update_link_info()
+or ice_init_phy_user_cfg(), causing probe to fail.
+
+An incorrect NVM update procedure can result in link/PHY errors, and
+the recommended resolution is to update the NVM using the correct
+procedure. If the driver fails probe due to link errors, the user
+cannot update the NVM to recover. The link/PHY errors logged are
+non-fatal: they are already annotated as 'not a fatal error if this
+fails'.
+
+Since none of the errors inside ice_init_link() should prevent probe
+from completing, convert it to void and remove the error check in the
+caller. All failures are already logged; callers have no meaningful
+recovery path for link init errors.

+Subject: irqchip/crossbar: Use correct index in crossbar_domain_free()
+
+From: Bhargav Joshi <j.bhargav.u@gmail.com>
+
+commit 043db005a8d6932dc7d217c86307e9af0bc10ddc upstream.
+
+crossbar_domain_free() resets the domain data and then uses the nulled
+out irq_data->hwirq member as index to reset the irq_map[] entry and to
+write the relevant crossbar register with a safe entry. That means it
+never frees the correct index and keeps the crossbar register connection
+to the source interrupt active.
+
+If it would not reset the domain data, then this would be even worse as
+irq_data->hwirq holds the source interrupt number, but both the map and
+register index need the corresponding GIC SPI number and not the source
+interrupt number. This might even result in an out of bounds access as
+the source interrupt number can be higher than the maximal index space.
+
+Fix this by using the GIC SPI index from the parent domain's irq_data.

+Subject: ksmbd: fix integer overflow in set_file_allocation_info()
+
+From: Ibrahim Hashimov <security@auditcode.ai>
+
+commit 1c0ae3df692ea2a4ce992f786346154e75a3f0d5 upstream.
+
+set_file_allocation_info() converts the client-supplied
+FILE_ALLOCATION_INFORMATION::AllocationSize into a 512-byte block
+count with:
+
+       alloc_blks = (le64_to_cpu(file_alloc_info->AllocationSize) + 511) >> 9;
+
+AllocationSize is a fully client-controlled __le64 field; the only
+validation performed by the caller (smb2_set_info_file(), case
+FILE_ALLOCATION_INFORMATION) is that the fixed buffer is at least
+sizeof(struct smb2_file_alloc_info) == 8 bytes. The value itself is
+never range-checked before this arithmetic.
+
+When AllocationSize is close to U64_MAX (e.g. 0xffffffffffffffff),
+"AllocationSize + 511" wraps around mod 2^64 to a small number
+(0xffffffffffffffff + 511 = 510), so alloc_blks becomes 0. Since any
+existing regular file has stat.blocks > 0, the function then takes
+the "shrink" branch and calls:
+
+       ksmbd_vfs_truncate(work, fp, alloc_blks * 512);   /* == 0 */
+
+silently truncating the file to size 0, even though the client asked
+to grow the allocation to (what looks like) the maximum possible
+size. The trailing "if (size < alloc_blks * 512) i_size_write(inode,
+size);" restore is guarded by a comparison that is never true once
+alloc_blks == 0, so the truncation is not undone. This lets an
+authenticated SMB client that already holds an open handle with
+FILE_WRITE_DATA on a file silently truncate that same file to size 0
+via a single crafted SET_INFO(FILE_ALLOCATION_INFORMATION) request
+advertising a near-U64_MAX AllocationSize, even though the request
+asks to grow the file's allocation rather than shrink it. This is a
+functional/data-loss bug, not a privilege-boundary
+violation: the same client could already truncate the file via
+FILE_END_OF_FILE_INFORMATION or a plain write.
+
+Fix it by validating AllocationSize against MAX_LFS_FILESIZE, the
+same upper bound the VFS itself uses to reject unrepresentable file
+sizes, before doing the "+511" rounding, and rejecting oversized
+values with -EINVAL. Bounding AllocationSize to
+MAX_LFS_FILESIZE - 511 guarantees the "+511" addition cannot wrap,
+and that the subsequent "alloc_blks * 512" values passed to
+vfs_fallocate() and ksmbd_vfs_truncate() stay within a representable
+loff_t as well.
+
+No legitimate SMB client asks for an allocation size anywhere near
+2^64 bytes, so this only rejects a value that was previously
+silently misinterpreted as zero.
+
+Runtime-verified on a v6.19 KASAN test stand: sending SET_INFO
+(FILE_ALLOCATION_INFORMATION) with AllocationSize = 0xffffffffffffffff
+against ksmbd now returns -EINVAL and leaves the target file's size
+unchanged, where the unpatched kernel truncated it from 4096 to 0
+bytes.

+
+commit 306e443156b82a2a14a3f33da908c303be45529c upstream.
+
+Die erase opcode is supported in multi-die devices only. For single die
+devices, default chip erase opcode must be used.
+
+In s25hx_t_late_init(), die erase opcode is set only when the device is
+multi-die.

+
+From: Miquel Raynal <miquel.raynal@bootlin.com>
+
+commit e1d456b26bf23e30db305a6184e8abd9ab68bbf2 upstream.
+
+In the case of the first block being locked (or the few first blocks),
+if the user want to fully unlock the device it has two possibilities:
+- either it asks to unlock the entire device, and this works;
+- or it asks to unlock just the block(s) that are currently locked,
+  which fails.
+
+It fails because the conditions "can_be_top" and "can_be_bottom" are
+true. Indeed, in this case, we unlock everything, so the TB bit does not
+matter. However in the current implementation, use_top would be true (as
+this is the favourite option) and lock_len, which in practice should be
+reduced down to 0, is set to "nor->params->size - (ofs + len)" which is
+a positive number. This is wrong.
+
+An easy way is to simply add an extra condition. In the unlock() path,
+if we can achieve the same result from both sides, it means we unlock
+everything and lock_len must simply be 0. A comment is added to clarify
+that logic.

+Subject: net: thunderbolt: Fix frags[] overflow by bounding frame_count
+
+From: Maoyi Xie <maoyixie.tju@gmail.com>
+
+commit 55d9895f89970501fe126d1026b586b04a224c27 upstream.
+
+tbnet_poll() assembles a multi-frame ThunderboltIP packet into one skb. The
+first frame goes into the skb linear area and every further frame is added as
+a page fragment.
+
+       skb_add_rx_frag(skb, skb_shinfo(skb)->nr_frags,
+                       page, hdr_size, frame_size,
+                       TBNET_RX_PAGE_SIZE - hdr_size);
+
+A packet of frame_count frames therefore ends up with frame_count - 1
+fragments. tbnet_check_frame() only bounds the peer supplied frame_count to
+TBNET_RING_SIZE / 4 (64), which is far above MAX_SKB_FRAGS (17 by default). A
+peer that sends a packet of 19 or more small frames pushes nr_frags past
+MAX_SKB_FRAGS, so skb_add_rx_frag() writes past skb_shinfo()->frags[] and
+corrupts memory after the shared info.
+
+Tighten the start of packet bound to MAX_SKB_FRAGS + 1 so a packet can never
+produce more fragments than frags[] can hold. This matches the recent skb
+frags overflow fixes in other receive paths, for example f0813bcd2d9d ("net:
+wwan: t7xx: fix potential skb->frags overflow in RX path") and 600dc40554dc
+("net: usb: cdc-phonet: fix skb frags[] overflow in rx_complete()").

+Subject: netdev-genl: report NAPI thread PID in the caller's pid namespace
+
+From: Maoyi Xie <maoyixie.tju@gmail.com>
+
+commit 1f24c0d01db214c9e661915e9972404c96ca73c0 upstream.
+
+netdev_nl_napi_fill_one() reports the NAPI kthread PID in NETDEV_A_NAPI_PID
+using task_pid_nr(), which returns the PID in the initial pid namespace.
+
+NETDEV_CMD_NAPI_GET does not have GENL_ADMIN_PERM and the netdev genl family
+is netnsok, so a caller in a child pid namespace can issue it. That caller
+then sees the kthread's global PID, even though the kthread is not visible
+in its pid namespace, where the value should be 0.
+
+Translate the PID through the caller's pid namespace, the same way commit
+3799c2570982 ("io_uring/fdinfo: translate SqThread PID through caller's
+pid_ns") did for the io_uring SQPOLL thread. The doit and dumpit paths both
+run synchronously in the caller's context, so task_active_pid_ns(current) is
+the caller's pid namespace.

+Subject: NFS: Charge unstable writes by request size, not folio size
+
+From: Benjamin Coddington <ben.coddington@hammerspace.com>
+
+commit 27934d02cbeb8a957dd11c985a579e58d30c5270 upstream.
+
+nfs_folio_mark_unstable() and nfs_folio_clear_commit() charge and
+uncharge NR_WRITEBACK/WB_WRITEBACK by folio_nr_pages(folio) once per
+*request* added to or removed from a commit list. This is correct only
+when a folio has a single associated request. When pg_test splits a
+folio into N sub-folio requests (e.g. pNFS flexfiles striping with a
+stripe unit smaller than the folio size, or plain wsize-limited
+splitting), each of the N requests independently charges the whole
+folio's page count, inflating the accounting by a factor of N per
+folio. With large folios and small stripe units this reaches multiple
+orders of magnitude: a 2 MiB folio split into 512 4 KiB requests can
+charge up to 512x its real size, pushing global dirty+writeback
+accounting past the system's dirty threshold and forcing every
+buffered writer on the host into the hard-throttle path, including
+unrelated in-kernel NFS server threads sharing the box.
+
+Charge each request only for the pages it actually covers.

+Subject: nvmet-rdma: handle inline data with a nonzero offset
+
+From: Bryam Vargas <hexlabsecurity@proton.me>
+
+commit 48c0162f647bb47e6084ffbc71b8f213f5e2f4f8 upstream.
+
+nvmet_rdma_use_inline_sg() maps the host-controlled inline data offset
+into the per-command inline scatterlist.  The bounds check admits any
+offset with off + len <= inline_data_size, but the mapping still assumes
+the data begins in the first inline page:
+
+       sg->offset = off;
+       sg->length = min_t(int, len, PAGE_SIZE - off);
+
+When a port is configured with inline_data_size > PAGE_SIZE (settable up
+to max(SZ_16K, PAGE_SIZE)), an offset in (PAGE_SIZE, inline_data_size]
+makes "PAGE_SIZE - off" underflow, so sg->length is set to ~4 GiB and
+the block backend reads far past the first inline page.  num_pages(len)
+also ignores the offset, so an in-bounds offset whose [off, off+len)
+span crosses a page boundary under-counts the scatterlist.
+
+Map the offset properly: split it into a page index and an in-page
+offset, start the scatterlist at that page, and size the page count from
+page_off + len.  Because the request scatterlist may now start at
+inline_sg[page_idx] rather than inline_sg[0], generalize the inline-SGL
+identity test in nvmet_rdma_release_rsp() to a range test; otherwise the
+persistent inline scatterlist is mistaken for an allocated one and
+nvmet_req_free_sgls() frees an inline page (and warns in
+free_large_kmalloc()).

+Subject: pkey: Move keytype check from pkey api to handler
+
+From: Holger Dengler <dengler@linux.ibm.com>
+
+commit 754e9e49b76fd5be339172aa98544182ed3ca75e upstream.
+
+The PKEY_VERIFYPROTK ioctl takes data from user-space and verifies the
+contained protected key. While checking the integrity of the ioctl
+request structure is the responsibility of the generic pkey_api code,
+the verification of the contained protected key is the responsibility
+of the pkey handler.
+
+The keytype verification (based on the calculated bitsize of the key)
+is part of the protected key verification and therefore the
+responsibility of the pkey handler (which already verifies
+it). Therefore the keytype verification is removed from the generic
+pkey_api code.
+
+As the calculation of the key bitsize is currently wrong, the removal
+of the keytype check in pkey_api also removes this wrong
+calculation. For this reason, the commit is flagged with the Fixes:
+tag.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Daniel Gibson <daniel@gibson.sh>
+
+commit 428b9fd2dce50b4dc5cd9ade10b92efcf57ce7aa upstream.
+
+Enabling the new delay_suspend module parameter delays suspend for
+2.5 seconds which is known to help for some AMD-based Lenovo Laptops
+that otherwise failed to send/receive events for key presses or the
+lid switch after s2idle. Apparently the EC needs to do some things
+in the background before suspend or it gets into a bad state.
+
+There are many reports of AMD-based laptops (mostly but not exclusively
+IdeaPads) about similar issues on the web; this parameter gives
+affected users an easy way to try out if their issues have the same
+root cause and to work around them until their specific device is added
+to the quirks list.
+
+The parameter description has a note encouraging users to report
+their device so it can be added to the quirks list, inspired by a
+similar request in parameter descriptions of the ideapad-laptop module.
+
+The module parameter can be set to "1" to explicitly enable it,
+"0" to disable it even on devices that are assumed to be affected,
+or -1 (the default) to enable it if the device is assumed to be affected
+(according to fwbug_list[])

+Subject: platform/x86/amd/pmc: Delay suspend for some Lenovo Laptops
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Daniel Gibson <daniel@gibson.sh>
+
+commit 9b9e60dd31da054a37d601e9fcabdfd8a2bff354 upstream.
+
+Some IdeaPad Slim 3 devices and similar with AMD CPUs have a
+nonfunctional keyboard and lid switch after s2idle.
+
+It helps to delay suspend by 2.5 seconds so the EC has some time
+to do whatever it needs to get done before suspend - unfortunately
+at least on my 16ABR8 waking it with a timer (wakealarm) still
+triggers the issue, but at least normal resume via keypress or
+lid works fine. On the 14ARP10 wakealarm has been reported to also
+work fine with this patch.
+
+This issue has been reported for many different devices, this patch
+has been tested with the Zen3-based IdeaPad Slim 3 16ABR8 (82XR)
+and the Zen3+-based IdeaPad Slim 3 14ARP10 (83K6) and IdeaPad Slim 3
+15ARP10 (83MM).

+
+commit 037f0b03c663a247366673a807834389107995b7 upstream.
+
+The ECs in the IdeaPads that need the delay_suspend quirk send lots
+of messages when charging, which not only causes intermediate wakeups
+when suspended, but also prevents the device from reaching the deepest
+suspend state.
+
+Because of this amd_pmc_intermediate_wakeup_need_delay() returns false
+during intermediate wakeups and amd_pmc_want_suspend_delay() is called.
+So far it always logged its "Delaying suspend by 2.5s ..." messages
+then, which spams dmesg. This commit makes sure that those messages are
+only logged once per suspend.

+
+commit 6e9cab2247e5b243ae2d907ce7c948a8a9c8d61a upstream.
+
+dell_init() initializes several resources after dell_setup_rfkill(),
+including the optional touchpad LED, keyboard backlight LED, battery
+hook, debugfs directory and dell-laptop notifier.
+
+If a later LED or backlight registration fails, the error path only
+tears down the battery hook and rfkill resources. This leaves the
+notifier, debugfs directory, keyboard backlight LED and optional
+touchpad LED registered after dell_init() returns an error.
+
+Add the missing cleanup calls before tearing down rfkill.
+
+Fixes: 9c656b07997f ("platform/x86: dell-*: Call new led hw_changed API on kbd brightness change")

+Explicitly check the length of the target buffer in the pkey_pckmo
+implementation of the key_to_protkey() handler function. The handler
+function fails, if the generated output data exceeds the length of the
+provided target buffer.

+Subject: scsi: elx: efct: Fix refcount leak in efct_hw_io_abort()
+
+From: WenTao Liang <vulab@iscas.ac.cn>
+
+commit 2c007acf7b31c39c08ce4959451ad00b19be4c1f upstream.
+
+When efct_hw_reqtag_alloc() fails in efct_hw_io_abort(), the error path
+returns -ENOSPC without releasing the reference obtained via
+kref_get_unless_zero() earlier in the function. All other error paths
+correctly drop the reference. This causes a permanent reference leak on the
+io_to_abort object.
+
+Additionally, the abort_in_progress flag is left set to true on this path,
+which means future abort attempts for the same I/O will immediately return
+-EINPROGRESS even though the abort was never submitted, effectively
+blocking recovery.
+
+Fix this by adding the missing kref_put() call and reset abort_in_progress
+to false, matching the cleanup done in the efct_hw_wq_write() failure path
+below.

+
+From: Xu Rao <raoxu@uniontech.com>
+
+commit 1d3a742afeb761eaead774691bde1ced699e9a5d upstream.
+
+SG_GET_REQUEST_TABLE reports per-request diagnostic state through
+sg_req_info::problem. The field is meant to indicate whether there is an
+error to report for a completed request.
+
+sg_fill_request_table() currently combines masked_status, host_status
+and driver_status with bitwise AND. This only reports a problem when all
+three status fields are non-zero at the same time. A normal target check
+condition, for example, has masked_status set while host_status and
+driver_status may both be zero, so the request is incorrectly reported
+as clean.
+
+Use the same condition as sg_new_read(), which sets SG_INFO_CHECK when
+any of the three status fields is non-zero.

+Subject: scsi: target: Bound PR-OUT TransportID parsing to the received buffer
+
+From: Bryam Vargas <hexlabsecurity@proton.me>
+
+commit d04a179085c262c9ed577d0a4cbc6482ff1fd9a3 upstream.
+
+core_scsi3_decode_spec_i_port() and core_scsi3_emulate_register_and_move()
+hand the raw PERSISTENT RESERVE OUT parameter buffer to
+target_parse_pr_out_transport_id() without telling it how many bytes are
+valid.  For an iSCSI TransportID (FORMAT CODE 01b),
+iscsi_parse_pr_out_transport_id() locates the ",i,0x" ISID separator with
+an unbounded strstr() (and on the error path prints the name with a further
+unbounded "%s").  An initiator can submit a TransportID whose iSCSI name
+contains neither a ",i,0x" substring nor a NUL terminator, filling the
+parameter list to its end, so the scan runs off the end of the buffer.
+
+When the parameter list spans more than one page the buffer is a multi-page
+vmap (transport_kmap_data_sg()), so the over-read walks into the trailing
+vmalloc guard page and oopses (KASAN: vmalloc-out-of-bounds in strstr).  It
+is reachable by any fabric that delivers a PR OUT to a device exported
+through an iSCSI TPG, including a guest via vhost-scsi.
+
+Pass the number of received bytes down to the parser and validate the iSCSI
+TransportID's own self-described length (ADDITIONAL LENGTH + 4) once, up
+front: reject it if it is below the spc4r17 minimum or larger than the
+received buffer, then bound the separator search, the ISID walk and the
+name copy by that length.  This is the length check the callers already
+perform after the parse (core_scsi3_decode_spec_i_port() compares tid_len
+against tpdl, core_scsi3_emulate_register_and_move() validates it against
+data_length), moved ahead of the scan.  Also drop the unbounded "%s" of the
+unterminated name.
+
+Add per-format explicit name-length checks before copying into i_str,
+rather than silently truncating with min_t: for FORMAT CODE 00b reject if
+the descriptor body (tid_len - 4 bytes) cannot fit in
+i_str[TRANSPORT_IQN_LEN]; for FORMAT CODE 01b reject if the name portion
+(from &buf[4] up to the separator) cannot fit.  Both checks make the bounds
+intent explicit at each format branch.
+
+While here, also reject a FORMAT CODE 01b TransportID whose ",i,0x"
+separator sits at the very end of the descriptor: that leaves an empty ISID
+and points the returned port nexus pointer at buf + tid_len, one past the
+descriptor, which the registration code (__core_scsi3_locate_pr_reg(),
+__core_scsi3_alloc_registration()) then dereferences as the ISID string --
+the same over-read of the parameter buffer for a malformed descriptor.

+Subject: scsi: target: core: Fix iSCSI ISID use-after-free in REGISTER AND MOVE
+
+From: Bryam Vargas <hexlabsecurity@proton.me>
+
+commit fda6a1f3c3d7047b5ce5654487649c2daa738bfc upstream.
+
+core_scsi3_emulate_pro_register_and_move() maps the PERSISTENT RESERVE OUT
+parameter list with transport_kmap_data_sg() and parses the destination
+TransportID with target_parse_pr_out_transport_id(). For an iSCSI
+TransportID (FORMAT CODE 01b), iscsi_parse_pr_out_transport_id() returns
+the ISID in iport_ptr as a raw pointer into that mapped buffer.
+
+The function then unmaps the buffer with transport_kunmap_data_sg() before
+dereferencing iport_ptr in strcmp(), __core_scsi3_locate_pr_reg() and
+core_scsi3_alloc_registration(). When the parameter list spans more than
+one page (PARAMETER LIST LENGTH > 4096), transport_kmap_data_sg() uses
+vmap() and transport_kunmap_data_sg() does vunmap(), so the kernel virtual
+address backing iport_ptr is torn down and every subsequent dereference is
+a use-after-free read of the unmapped region.
+
+Keep the parameter list mapped until iport_ptr is no longer needed: drop
+the early transport_kunmap_data_sg() and unmap once on the success path,
+right before returning. The error paths already unmap through the existing
+"if (buf) transport_kunmap_data_sg(cmd)" at the out: label, which now runs
+on every post-map error exit because buf is no longer cleared early. Only
+reads of the mapping happen while spinlocks are held; the map and unmap
+calls remain outside any lock. The sibling caller
+core_scsi3_decode_spec_i_port() already uses the buffer before unmapping it
+and is left unchanged.

+Subject: scsi: xen: scsiback: Free the command tag on the TMR submit-failure path
+
+From: Michael Bommarito <michael.bommarito@gmail.com>
+
+commit 66aefc277ebb796ec285d550305535dc3fc0179f upstream.
+
+scsiback_device_action() obtains a command tag in
+scsiback_get_pend_req() and submits a task-management request with
+target_submit_tmr(). When target_submit_tmr() fails it returns < 0 and
+scsiback jumps to the err: label, which sends a response but frees
+nothing, leaking the tag.
+
+Impact: a pvSCSI guest can leak the command tags of a LUN's session,
+stopping the LUN, by issuing VSCSIIF_ACT_SCSI_ABORT or RESET requests
+whenever target_submit_tmr() fails.
+
+transport_generic_free_cmd() cannot be used here. By the time
+target_submit_tmr() returns an error it has already run
+__target_init_cmd() (so se_cmd->cmd_kref is one, not zero), and on its
+target_get_sess_cmd() error path it has freed se_cmd->se_tmr_req via
+core_tmr_release_req() while leaving SCF_SCSI_TMR_CDB set and the
+pointer dangling. Letting the command release run target_free_cmd_mem()
+would then double-free se_tmr_req.
+
+Use the same helper, which returns just the tag, on this path too.

+the se_cmd is initialised (kref_init() via target_init_cmd()) only
+later, in scsiback_cmd_exec(), on the successful VSCSIIF_ACT_SCSI_CDB
+path. The two error paths in scsiback_do_cmd_fn() taken before the
+command is submitted -- a failed scsiback_gnttab_data_map() and an
+unknown ring_req.act -- call
+transport_generic_free_cmd(&pending_req->se_cmd, 0), which kref_put()s a
+refcount of 0. That underflows it ("refcount_t: underflow;
+use-after-free") and, as the release function is not run, leaks the
+command tag.
+
+Impact: a pvSCSI guest can leak every command tag of a LUN's session,
+stopping the LUN, by submitting requests with a bad grant reference or
+an unknown request type; under panic_on_warn the refcount underflow
+panics the host.
+
+Add a helper that just returns the tag with target_free_tag() and sends
+the error response. It frees the tag while the v2p reference still pins
+the session, and snapshots the response fields beforehand because
+freeing the tag can let another ring reuse the pending_req slot.

+Subject: sctp: validate STALE_COOKIE cause length before reading staleness
+
+From: Weiming Shi <bestswngs@gmail.com>
+
+commit 1cd23ca80784223fa2204e16203f754da4e821f8 upstream.
+
+When an ERROR chunk with a STALE_COOKIE cause is received in the
+COOKIE_ECHOED state, sctp_sf_do_5_2_6_stale() reads the 4-byte Measure
+of Staleness that follows the cause header:
+
+       err   = (struct sctp_errhdr *)(chunk->skb->data);
+       stale = ntohl(*(__be32 *)((u8 *)err + sizeof(*err)));
+
+err is the first cause in the chunk, not the STALE_COOKIE cause that
+caused the dispatch, and nothing guarantees the staleness field is
+present. sctp_walk_errors() only requires a cause to be as long as the
+4-byte header, so for a STALE_COOKIE cause of length 4 the read runs
+past the cause, and for a minimal ERROR chunk past skb->tail. The value
+is echoed to the peer in the Cookie Preservative of the reply INIT,
+leaking uninitialized memory.
+
+sctp_sf_cookie_echoed_err() already walks to the STALE_COOKIE cause, so
+check its length there and pass it to sctp_sf_do_5_2_6_stale(), which
+reads that cause instead of the first one. A STALE_COOKIE cause too
+short to hold the staleness field is discarded.
+
+The read is reachable by any peer that can drive an association into
+COOKIE_ECHOED, including an unprivileged process using a raw SCTP socket
+in a user and network namespace.

+Subject: smb: client: use kvzalloc() for megabyte buffer in simple fallocate
+
+From: Fredric Cover <fredric.cover.lkernel@gmail.com>
+
+commit 806c00c23e3ce8eae397a40ced536ef88ae4e012 upstream.
+
+Currently in smb3_simple_fallocate_range(), a 1 MB buffer is allocated
+using kzalloc(). Under heavy memory fragmentation, a contiguous 1 MB block
+of physical memory (an order-8 allocation) may not be available,
+causing the allocation to fail.
+
+This failure was observed during xfstests generic/013 on a 4GB RAM
+test machine running fsstress:
+
+fsstress: page allocation failure: order:8,
+mode:0x40dc0(GFP_KERNEL|__GFP_ZERO|__GFP_COMP),
+nodemask=(null),cpuset=/,mems_allowed=0

+
+Since this scratch buffer does not require physically contiguous memory,
+switch the allocation to kvzalloc(). This retains the performance
+benefits of kmalloc() under normal conditions, while gracefully falling
+back to virtually contiguous memory when physical allocation fails.

+Subject: spi: uniphier: Fix completion initialization order before devm_request_irq()
+
+From: Kunihiko Hayashi <hayashi.kunihiko@socionext.com>
+
+commit f3ad1c87d8201e54b66bd6072442f0b5d5a308ee upstream.
+
+The driver calls devm_request_irq() before initializing the completion
+used by the interrupt handler. Because the interrupt may occur immediately
+after devm_request_irq(), the handler may execute before init_completion().
+
+This may result in calling complete() on an uninitialized completion,
+causing undefined behavior. This has been observed with KASAN.
+
+Fix this by initializing the completion before registering the IRQ.

+Subject: taskstats: retain dead thread stats in TGID queries
+
+From: Yiyang Chen <cyyzero16@gmail.com>
+
+commit b3e4fbb04220efc3bc022bcf31b5689d39c6b111 upstream.
+
+Patch series "taskstats: fix TGID dead-thread stat retention", v3.
+
+This series fixes a taskstats TGID aggregation bug where fields added in
+the TGID query path were not preserved after thread exit, and adds a
+kselftest covering the regression.
+
+The first patch keeps the cached TGID aggregate used for dead threads in
+step with the fields already accumulated for live threads, and also fixes
+the final TGID exit notification emitted when group_dead is true.
+
+The second patch adds a kselftest that verifies TGID CPU stats do not
+regress after a worker thread exits and has been reaped.
+
+
+This patch (of 2):
+
+fill_stats_for_tgid() builds TGID stats from two sources: the cached
+aggregate in signal->stats and a scan of the live threads in the group.
+
+However, fill_tgid_exit() only accumulates delay accounting into
+signal->stats.  This means that once a thread exits, TGID queries lose the
+fields that fill_stats_for_tgid() adds for live threads.
+
+This gap was introduced incrementally by two earlier changes that extended
+fill_stats_for_tgid() but did not make the corresponding update to
+fill_tgid_exit():
+
+- commit 8c733420bdd5 ("taskstats: add e/u/stime for TGID command")
+  added ac_etime, ac_utime, and ac_stime to the TGID query path.
+- commit b663a79c1915 ("taskstats: add context-switch counters")
+  added nvcsw and nivcsw to the TGID query path.
+
+As a result, those fields were accounted for live threads in TGID queries,
+but were dropped from the cached TGID aggregate after thread exit.  The
+final TGID exit notification emitted when group_dead is true also copies
+that cached aggregate, so it loses the same fields.
+
+Factor the per-task TGID accumulation into tgid_stats_add_task() and use
+it in both fill_stats_for_tgid() and fill_tgid_exit().  This keeps the
+cached aggregate used for dead threads aligned with the live-thread
+accumulation used by TGID queries.

+Subject: time: Fix off-by-one in compat settimeofday() usec validation
+
+From: Wang Yan <wangyan01@kylinos.cn>
+
+commit 269f2b43fae692d1f3988c9f888a6301aa537b82 upstream.
+
+The compat version of settimeofday() uses '>' instead of '>=' when
+validating tv_usec against USEC_PER_SEC, allowing the value 1000000 to pass
+the check. After the subsequent conversion to nanoseconds (tv_nsec *=
+NSEC_PER_USEC), this results in tv_nsec == NSEC_PER_SEC, which violates the
+timespec invariant that tv_nsec must be strictly less than NSEC_PER_SEC.
+
+The native settimeofday() was already fixed in commit ce4abda5e126 ("time:
+Fix off-by-one in settimeofday() usec validation"), but the compat
+counterpart was missed.
+
+Fix it by using '>=' to reject tv_usec values outside the valid range [0,
+USEC_PER_SEC - 1].

+
+commit 1a58f6115bfb34eabcc7de8a3a9745b219179781 upstream.
+
+Commit 186d124f07da ("tpm_eventlog.c: fix binary_bios_measurements")
+split the output to write the endian-converted event header first and
+then the variable-length event data.
+
+However, the split was at sizeof(struct tcpa_event) - 1, even though
+event_data was a zero-length array, and later a flexible array member,
+both of which already excluded the event data.
+
+Therefore, the current code writes the first three bytes of event_size
+from the endian-converted header and then the last byte from the raw
+header, which can emit a corrupted event_size on PPC64, where
+do_endian_conversion() maps to be32_to_cpu().
+
+Split one byte later to write the full endian-converted header first,
+followed by the variable-length event->event_data.

+Subject: tpm: Make the TPM character devices non-seekable
+
+From: Jaewon Yang <yong010301@gmail.com>
+
+commit f20d61c22bcaf172d6790b6500e3838e532e71c8 upstream.
+
+The TPM character devices expose a sequential command/response
+interface, but their open handlers leave FMODE_PREAD and FMODE_PWRITE
+enabled.
+
+After a command leaves a response pending, pread(fd, buf, 16, 0x1400)
+passes 0x1400 as *off to tpm_common_read(). The transfer length is
+bounded by response_length, but the offset is used unchecked when
+forming data_buffer + *off. A sufficiently large offset therefore causes
+an out-of-bounds heap read through copy_to_user() and, if the copy
+succeeds, an out-of-bounds zero-write through the following memset().
+
+Positional I/O does not provide coherent semantics for this interface.
+An arbitrary pread offset cannot represent how much of a response has
+been consumed sequentially. The write callback always stores a command
+at the start of data_buffer, while pwrite() does not update file->f_pos
+and can leave the sequential read cursor stale.
+
+Call nonseekable_open() from both open handlers. This removes
+FMODE_PREAD and FMODE_PWRITE, causing positional reads and writes to
+fail with -ESPIPE before reaching the TPM callbacks, and explicitly
+marks the files non-seekable. Normal read() and write() continue to use
+the existing sequential f_pos cursor, leaving the response state machine
+unchanged.
+
+Tested on Linux 6.12 with KASAN and a swtpm TPM2 device:
+
+ - sequential partial reads returned the complete response
+ - pread() and preadv() with offset 0x1400 returned -ESPIPE
+ - pwrite() and pwritev() with offset zero returned -ESPIPE
+ - the pending response remained intact after the rejected operations
+ - a subsequent normal command/response cycle completed normally
+ - no KASAN report was produced.
+
+Fixes: 9488585b21be ("tpm: add support for partial reads")

+Subject: tpm: tpm2-sessions: wait for async KPP completion in tpm_buf_append_salt
+
+From: Michael Bommarito <michael.bommarito@gmail.com>
+
+commit 73851a7c43dfa52d2ed9415889b33daf85da0ed9 upstream.
+
+tpm_buf_append_salt() in drivers/char/tpm/tpm2-sessions.c calls
+crypto_kpp_generate_public_key() and crypto_kpp_compute_shared_secret()
+without installing a completion callback, discards both return values,
+and immediately frees the kpp_request via kpp_request_free(). When the
+resolved ecdh-nist-p256 KPP backend is asynchronous (atmel-ecc, HPRE,
+keembay-ocs), either operation returns -EINPROGRESS and the deferred
+completion worker dereferences the freed request.
+
+The path fires automatically from the hwrng_fillfn kernel thread via
+tpm_get_random -> tpm2_get_random -> tpm2_start_auth_session ->
+tpm_buf_append_salt on every entropy poll, without any userland action.
+
+Install crypto_req_done as the completion callback, wrap both KPP
+operations in crypto_wait_req(), and propagate errors to the caller.
+The wait is a no-op for synchronous backends.

+Subject: tpm: tpm_tis_spi: Use wait_woken() in wait_for_tmp_stat()
+
+From: Jarkko Sakkinen <jarkko@kernel.org>
+
+commit c0c9cfb3b75def8bf200a2d4db09015806acfeaf upstream.
+
+wait_event_interruptible_timeout() evaluates its condition after setting
+the current task state to TASK_INTERRUPTIBLE.
+
+With CONFIG_DEBUG_ATOMIC_SLEEP this triggers a warning when the IRQ wait
+path is used:
+
+    tpm_tis_status()
+      tpm_tis_spi_read_bytes()
+        tpm_tis_spi_transfer_full()
+          spi_bus_lock()
+            mutex_lock()
+
+Address this with the following measures:
+
+1. Call wait_tpm_stat_cond() only while tasking is running.
+2. Use wait_woken() to wait for changes.

+Subject: xen/gntdev: fix error handling in ioctl
+
+From: Wentao Liang <vulab@iscas.ac.cn>
+
+commit 45ca1afe2fd14c04e37227e79d3f8455831d8408 upstream.
+
+When gntdev_ioctl_map_grant_ref() fails to copy the operation result
+back to userspace after successfully adding the mapping to the list,
+the error path returns -EFAULT without releasing the reference
+acquired by gntdev_alloc_map(). The mapping remains in priv->maps
+with a refcount of 1, causing a memory leak and a dangling list
+entry.
+
+Additionally, gntdev_add_map() may modify map->index to avoid overlap
+with existing mappings. Therefore, the index returned to userspace
+must be obtained after gntdev_add_map() completes.
+
+Fix this by holding the mutex across gntdev_add_map(), retrieving
+the correct index, and copy_to_user(). If copy_to_user() fails,
+remove the mapping from the list and release the reference while
+still holding the lock.
+
+Cc: stable@vger.kernel.org
+
+Fix these issues by properly handling all error cases.

+Subject: xfrm: use compat translator only for u64 alignment mismatch
+
+From: Sanman Pradhan <psanman@juniper.net>
+
+commit 355fbcbdc2539cca7890b0d0914d4ce0f985ad74 upstream.
+
+The XFRM compat layer (CONFIG_XFRM_USER_COMPAT) translates 32-bit xfrm
+netlink and setsockopt messages into the native 64-bit layout. It is
+only needed on architectures where the 32-bit and 64-bit ABIs disagree
+on u64 alignment, which the kernel encodes as COMPAT_FOR_U64_ALIGNMENT.
+
+That symbol is defined only by arch/x86. XFRM_USER_COMPAT depends on it,
+so the translator can never be built on any other architecture,
+including arm64, which still provides a 32-bit compat ABI (CONFIG_COMPAT)
+for AArch32 EL0 userspace. On arm64 the AArch32 EABI already aligns u64
+to 8 bytes, identical to the AArch64 ABI, so no translation is required
+and the native code path is correct for 32-bit tasks.
+
+However, xfrm_user_rcv_msg() and xfrm_user_policy() gate on
+in_compat_syscall() alone and then call xfrm_get_translator(), which
+returns NULL when no translator is registered. On arm64 that is always
+the case, so every xfrm netlink message and the XFRM_POLICY setsockopt
+issued by a 32-bit task returns -EOPNOTSUPP. A 32-bit userspace process
+on arm64 (and on any other arch with CONFIG_COMPAT but without
+COMPAT_FOR_U64_ALIGNMENT) therefore cannot configure XFRM state or
+policy through the XFRM_USER netlink API, and cannot use the XFRM_POLICY
+setsockopt path, because both fail before reaching the native parser.
+
+The translator series replaced the blanket compat rejection with a
+translator lookup. That made the path usable on x86 when the translator
+is available, but left architectures that cannot build the translator
+permanently rejected even when their compat layout already matches the
+native layout. Let those architectures use the native parser instead.
+
+Gate the translator requirement on COMPAT_FOR_U64_ALIGNMENT instead of
+on in_compat_syscall() alone. Gating on the ABI property rather than on
+CONFIG_XFRM_USER_COMPAT is deliberate: on x86 with IA32_EMULATION=y but
+XFRM_USER_COMPAT=n, a 32-bit task must still be rejected rather than
+routed through the native parser, which would misread genuinely
+4-byte-aligned x86-32 messages. COMPAT_FOR_U64_ALIGNMENT is the ABI
+property that makes the XFRM translator mandatory.
+
+Only the receive/input direction needs the guard. The send, dump and
+notification paths already call the translator as "if (xtr) { ... }"
+with no error on NULL, so on arches without a translator they no-op and
+the kernel emits native 64-bit-layout messages, which is what an AArch32
+task expects.
+
+Tested on Juniper SRX hardware: with the fix, 32-bit IPsec userspace
+netlink and XFRM_POLICY setsockopt operations that previously failed
+with -EOPNOTSUPP now succeed; x86 behaviour is unchanged by inspection.

+Subject: xfrm: xfrm_interface: require CAP_NET_ADMIN in the device netns for changelink
+
+From: Maoyi Xie <maoyixie.tju@gmail.com>
+
+commit 095515d89b19b6cc19dfcdc846f97403ed1ebce3 upstream.
+
+xfrmi_changelink() operates on at most two netns, dev_net(dev) and the
+interface link netns xi->net. They differ once the device is created in
+or moved to a netns other than the one the request runs in. The rtnl
+changelink path checks CAP_NET_ADMIN only against dev_net(dev), so a
+caller privileged there but not in xi->net can rewrite an interface that
+lives in xi->net.
+
+Gate xfrmi_changelink() on rtnl_dev_link_net_capable() at its top,
+before any attribute is parsed.
