[PATCH openEuler-1.0-LTS] drbd: Fix five use after free bugs in get_initial_state

From: Lv Yunlong <lyl2019(a)mail.ustc.edu.cn> stable inclusion from stable-v5.10.111 commit 594205b4936771a250f9d141e7e0fff21c3dd2d9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6VU CVE: CVE-2022-49085 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit aadb22ba2f656581b2f733deb3a467c48cc618f6 ] In get_initial_state, it calls notify_initial_state_done(skb,..) if cb->args[5]==1. If genlmsg_put() failed in notify_initial_state_done(), the skb will be freed by nlmsg_free(skb). Then get_initial_state will goto out and the freed skb will be used by return value skb->len, which is a uaf bug. What's worse, the same problem goes even further: skb can also be freed in the notify_*_state_change -> notify_*_state calls below. Thus 4 additional uaf bugs happened. My patch lets the problem callee functions: notify_initial_state_done and notify_*_state_change return an error code if errors happen. So that the error codes could be propagated and the uaf bugs can be avoid. v2 reports a compilation warning. This v3 fixed this warning and built successfully in my local environment with no additional warnings. v2: https://lore.kernel.org/patchwork/patch/1435218/ Fixes: a29728463b254 ("drbd: Backport the "events2" command") Signed-off-by: Lv Yunlong <lyl2019(a)mail.ustc.edu.cn> Reviewed-by: Christoph Böhmwalder <christoph.boehmwalder(a)linbit.com> Signed-off-by: Jens Axboe <axboe(a)kernel.dk> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: Wang Hai <wanghai38(a)huawei.com> Signed-off-by: Xiaomeng Zhang <zhangxiaomeng13(a)huawei.com> --- drivers/block/drbd/drbd_int.h | 8 ++--- drivers/block/drbd/drbd_nl.c | 41 ++++++++++++++++---------- drivers/block/drbd/drbd_state.c | 18 +++++------ drivers/block/drbd/drbd_state_change.h | 8 ++--- 4 files changed, 42 insertions(+), 33 deletions(-) diff --git a/drivers/block/drbd/drbd_int.h b/drivers/block/drbd/drbd_int.h index e35a234b0a8f..4f66cf6879fd 100644 --- a/drivers/block/drbd/drbd_int.h +++ b/drivers/block/drbd/drbd_int.h @@ -1688,22 +1688,22 @@ struct sib_info { }; void drbd_bcast_event(struct drbd_device *device, const struct sib_info *sib); -extern void notify_resource_state(struct sk_buff *, +extern int notify_resource_state(struct sk_buff *, unsigned int, struct drbd_resource *, struct resource_info *, enum drbd_notification_type); -extern void notify_device_state(struct sk_buff *, +extern int notify_device_state(struct sk_buff *, unsigned int, struct drbd_device *, struct device_info *, enum drbd_notification_type); -extern void notify_connection_state(struct sk_buff *, +extern int notify_connection_state(struct sk_buff *, unsigned int, struct drbd_connection *, struct connection_info *, enum drbd_notification_type); -extern void notify_peer_device_state(struct sk_buff *, +extern int notify_peer_device_state(struct sk_buff *, unsigned int, struct drbd_peer_device *, struct peer_device_info *, diff --git a/drivers/block/drbd/drbd_nl.c b/drivers/block/drbd/drbd_nl.c index 5b15ffd0c7f5..5a80453be553 100644 --- a/drivers/block/drbd/drbd_nl.c +++ b/drivers/block/drbd/drbd_nl.c @@ -4598,7 +4598,7 @@ static int nla_put_notification_header(struct sk_buff *msg, return drbd_notification_header_to_skb(msg, &nh, true); } -void notify_resource_state(struct sk_buff *skb, +int notify_resource_state(struct sk_buff *skb, unsigned int seq, struct drbd_resource *resource, struct resource_info *resource_info, @@ -4640,16 +4640,17 @@ void notify_resource_state(struct sk_buff *skb, if (err && err != -ESRCH) goto failed; } - return; + return 0; nla_put_failure: nlmsg_free(skb); failed: drbd_err(resource, "Error %d while broadcasting event.

[PATCH openEuler-1.0-LTS] f2fs: fix dereference of stale list iterator after loop body

31 Mar '25

From: Jakob Koschel <jakobkoschel(a)gmail.com> stable inclusion from stable-v4.19.247 commit 385edd3ce5b4b1e9d31f474a5e35a39779ec1110 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBP3SH CVE: CVE-2022-49425 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 2aaf51dd39afb6d01d13f1e6fe20b684733b37d5 ] The list iterator variable will be a bogus pointer if no break was hit. Dereferencing it (cur->page in this case) could load an out-of-bounds/undefined value making it unsafe to use that in the comparision to determine if the specific element was found. Since 'cur->page' *can* be out-ouf-bounds it cannot be guaranteed that by chance (or intention of an attacker) it matches the value of 'page' even though the correct element was not found. This is fixed by using a separate list iterator variable for the loop and only setting the original variable if a suitable element was found. Then determing if the element was found is simply checking if the variable is set.

[PATCH OLK-6.6] tracing: Fix use-after-free in print_graph_function_flags during tracer switching
by Tengda Wu 29 Mar '25

29 Mar '25

From: Tengda Wu <wutengda(a)huaweicloud.com> mainline inclusion from mainline-v6.15 commit 7f81f27b1093e4895e87b74143c59c055c3b1906 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBWWU7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Kairui reported a UAF issue in print_graph_function_flags() during ftrace stress testing [1]. This issue can be reproduced if puting a 'mdelay(10)' after 'mutex_unlock(&trace_types_lock)' in s_start(), and executing the following script: $ echo function_graph > current_tracer $ cat trace > /dev/null & $ sleep 5 # Ensure the 'cat' reaches the 'mdelay(10)' point $ echo timerlat > current_tracer The root cause lies in the two calls to print_graph_function_flags within print_trace_line during each s_show(): * One through 'iter->trace->print_line()'; * Another through 'event->funcs->trace()', which is hidden in print_trace_fmt() before print_trace_line returns. Tracer switching only updates the former, while the latter continues to use the print_line function of the old tracer, which in the script above is print_graph_function_flags. Moreover, when switching from the 'function_graph' tracer to the 'timerlat' tracer, s_start only calls graph_trace_close of the 'function_graph' tracer to free 'iter->private', but does not set it to NULL. This provides an opportunity for 'event->funcs->trace()' to use an invalid 'iter->private'. To fix this issue, set 'iter->private' to NULL immediately after freeing it in graph_trace_close(), ensuring that an invalid pointer is not passed to other tracers. Additionally, clean up the unnecessary 'iter->private = NULL' during each 'cat trace' when using wakeup and irqsoff tracers.

[PATCH openEuler-1.0-LTS] tracing: Make sure trace_printk() can output as soon as it can be used
by Tengda Wu 29 Mar '25

29 Mar '25

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> stable inclusion from stable-v4.19.272 commit b94d7c7654356860dd7719120c7d15ba38b6162a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBWVXX CVE: CVE-2023-53007 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 3bb06eb6e9acf7c4a3e1b5bc87aed398ff8e2253 upstream. Currently trace_printk() can be used as soon as early_trace_init() is called from start_kernel(). But if a crash happens, and "ftrace_dump_on_oops" is set on the kernel command line, all you get will be: [ 0.456075] <idle>-0 0dN.2. 347519us : Unknown type 6 [ 0.456075] <idle>-0 0dN.2. 353141us : Unknown type 6 [ 0.456075] <idle>-0 0dN.2. 358684us : Unknown type 6 This is because the trace_printk() event (type 6) hasn't been registered yet. That gets done via an early_initcall(), which may be early, but not early enough. Instead of registering the trace_printk() event (and other ftrace events, which are not trace events) via an early_initcall(), have them registered at the same time that trace_printk() can be used. This way, if there is a crash before early_initcall(), then the trace_printk()s will actually be useful.

[PATCH openEuler-1.0-LTS] drbd: Fix five use after free bugs in get_initial_state
by Xiaomeng Zhang 29 Mar '25

29 Mar '25

From: Lv Yunlong <lyl2019(a)mail.ustc.edu.cn> stable inclusion from stable-v5.10.111 commit 594205b4936771a250f9d141e7e0fff21c3dd2d9 bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBX1EN Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit aadb22ba2f656581b2f733deb3a467c48cc618f6 ] In get_initial_state, it calls notify_initial_state_done(skb,..) if cb->args[5]==1. If genlmsg_put() failed in notify_initial_state_done(), the skb will be freed by nlmsg_free(skb). Then get_initial_state will goto out and the freed skb will be used by return value skb->len, which is a uaf bug. What's worse, the same problem goes even further: skb can also be freed in the notify_*_state_change -> notify_*_state calls below. Thus 4 additional uaf bugs happened. My patch lets the problem callee functions: notify_initial_state_done and notify_*_state_change return an error code if errors happen. So that the error codes could be propagated and the uaf bugs can be avoid. v2 reports a compilation warning. This v3 fixed this warning and built successfully in my local environment with no additional warnings. v2: https://lore.kernel.org/patchwork/patch/1435218/ Fixes: a29728463b254 ("drbd: Backport the "events2" command") Signed-off-by: Lv Yunlong <lyl2019(a)mail.ustc.edu.cn> Reviewed-by: Christoph Böhmwalder <christoph.boehmwalder(a)linbit.com> Signed-off-by: Jens Axboe <axboe(a)kernel.dk> Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: Wang Hai <wanghai38(a)huawei.com> Signed-off-by: Xiaomeng Zhang <zhangxiaomeng13(a)huawei.com> --- drivers/block/drbd/drbd_int.h | 8 ++--- drivers/block/drbd/drbd_nl.c | 41 ++++++++++++++++---------- drivers/block/drbd/drbd_state.c | 18 +++++------ drivers/block/drbd/drbd_state_change.h | 8 ++--- 4 files changed, 42 insertions(+), 33 deletions(-) diff --git a/drivers/block/drbd/drbd_int.h b/drivers/block/drbd/drbd_int.h index e35a234b0a8f..4f66cf6879fd 100644 --- a/drivers/block/drbd/drbd_int.h +++ b/drivers/block/drbd/drbd_int.h @@ -1688,22 +1688,22 @@ struct sib_info { }; void drbd_bcast_event(struct drbd_device *device, const struct sib_info *sib); -extern void notify_resource_state(struct sk_buff *, +extern int notify_resource_state(struct sk_buff *, unsigned int, struct drbd_resource *, struct resource_info *, enum drbd_notification_type); -extern void notify_device_state(struct sk_buff *, +extern int notify_device_state(struct sk_buff *, unsigned int, struct drbd_device *, struct device_info *, enum drbd_notification_type); -extern void notify_connection_state(struct sk_buff *, +extern int notify_connection_state(struct sk_buff *, unsigned int, struct drbd_connection *, struct connection_info *, enum drbd_notification_type); -extern void notify_peer_device_state(struct sk_buff *, +extern int notify_peer_device_state(struct sk_buff *, unsigned int, struct drbd_peer_device *, struct peer_device_info *, diff --git a/drivers/block/drbd/drbd_nl.c b/drivers/block/drbd/drbd_nl.c index 5b15ffd0c7f5..5a80453be553 100644 --- a/drivers/block/drbd/drbd_nl.c +++ b/drivers/block/drbd/drbd_nl.c @@ -4598,7 +4598,7 @@ static int nla_put_notification_header(struct sk_buff *msg, return drbd_notification_header_to_skb(msg, &nh, true); } -void notify_resource_state(struct sk_buff *skb, +int notify_resource_state(struct sk_buff *skb, unsigned int seq, struct drbd_resource *resource, struct resource_info *resource_info, @@ -4640,16 +4640,17 @@ void notify_resource_state(struct sk_buff *skb, if (err && err != -ESRCH) goto failed; } - return; + return 0; nla_put_failure: nlmsg_free(skb); failed: drbd_err(resource, "Error %d while broadcasting event.

[PATCH OLK-6.6] fs/dcache: fix bad unlock balance in shrink_dentry_list()
by Baokun Li 29 Mar '25

29 Mar '25

[PATCH openEuler-1.0-LTS] rxrpc: Fix listen() setting the bar too high for the prealloc rings

This means that listen(rxrpc_sock, 32) will cause an oops when the socket is closed because rxrpc_service_prealloc_one() allocated one too many calls and rxrpc_discard_prealloc() won't then be able to get rid of them because it'll think the ring is empty. rxrpc_release_calls_on_socket() then tries to abort them, but oopses because call->peer isn't yet set. Fix this by setting the maximum backlog to RXRPC_BACKLOG_MAX - 1 to match the ring capacity. BUG: kernel NULL pointer dereference, address: 0000000000000086 ...

[PATCH openEuler-1.0-LTS] tty: fix deadlock caused by calling printk() under tty_port->lock

From: Qi Zheng <zhengqi.arch(a)bytedance.com> stable inclusion from stable-v4.19.247 commit 04ee31678c128a6cc7bb057ea189a8624ba5a314 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP2T9 CVE: CVE-2022-49441 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 6b9dbedbe3499fef862c4dff5217cf91f34e43b3 ] pty_write() invokes kmalloc() which may invoke a normal printk() to print failure message. This can cause a deadlock in the scenario reported by syz-bot below: CPU0 CPU1 CPU2 ---- ---- ---- lock(console_owner); lock(&port_lock_key); lock(&port->lock); lock(&port_lock_key); lock(&port->lock); lock(console_owner); As commit dbdda842fe96 ("printk: Add console owner and waiter logic to load balance console writes") said, such deadlock can be prevented by using printk_deferred() in kmalloc() (which is invoked in the section guarded by the port->lock). But there are too many printk() on the kmalloc() path, and kmalloc() can be called from anywhere, so changing printk() to printk_deferred() is too complicated and inelegant. Therefore, this patch chooses to specify __GFP_NOWARN to kmalloc(), so that printk() will not be called, and this deadlock problem can be avoided.

From: Laurent Pinchart <laurent.pinchart(a)ideasonboard.com> stable inclusion from stable-v6.6.76 commit 6c36dcd662ec5276782838660f8533a7cb26be49 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPBDI CVE: CVE-2024-57980 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit c6ef3a7fa97ec823a1e1af9085cf13db9f7b3bac upstream. If the uvc_status_init() function fails to allocate the int_urb, it will free the dev->status pointer but doesn't reset the pointer to NULL. This results in the kfree() call in uvc_status_cleanup() trying to double-free the memory. Fix it by resetting the dev->status pointer to NULL after freeing it.

We hold oxu->lock in position (1) of thread 1, and use del_timer_sync() to wait timer to stop, but timer handler also need oxu->lock in position (2) of thread 2. As a result, oxu_bus_suspend() will block forever. This patch extracts del_timer_sync() from the protection of spin_lock_irq(), which could let timer handler to obtain the needed lock.

[PATCH OLK-6.6 V1] kernel: be more careful about dup_mmap() failures and uprobe registering
by Zicheng Qu 28 Mar '25

28 Mar '25

From: "Liam R. Howlett" <Liam.Howlett(a)Oracle.com> mainline inclusion from mainline-v6.14-rc1 commit 64c37e134b120fb462fb4a80694bfb8e7be77b14 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPBM0 CVE: CVE-2025-21709 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/comm… -------------------------------- If a memory allocation fails during dup_mmap(), the maple tree can be left in an unsafe state for other iterators besides the exit path. All the locks are dropped before the exit_mmap() call (in mm/mmap.c), but the incomplete mm_struct can be reached through (at least) the rmap finding the vmas which have a pointer back to the mm_struct. Up to this point, there have been no issues with being able to find an mm_struct that was only partially initialised. Syzbot was able to make the incomplete mm_struct fail with recent forking changes, so it has been proven unsafe to use the mm_struct that hasn't been initialised, as referenced in the link below. Although 8ac662f5da19f ("fork: avoid inappropriate uprobe access to invalid mm") fixed the uprobe access, it does not completely remove the race. This patch sets the MMF_OOM_SKIP to avoid the iteration of the vmas on the oom side (even though this is extremely unlikely to be selected as an oom victim in the race window), and sets MMF_UNSTABLE to avoid other potential users from using a partially initialised mm_struct. When registering vmas for uprobe, skip the vmas in an mm that is marked unstable. Modifying a vma in an unstable mm may cause issues if the mm isn't fully initialised.

[PATCH OLK-6.6 V1] scsi: ufs: core: Fix use-after free in init error and remove paths

From: André Draszik <andre.draszik(a)linaro.org> mainline inclusion from mainline-v6.14-rc2 commit f8fb2403ddebb5eea0033d90d9daae4c88749ada category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPCAA CVE: CVE-2025-21739 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/comm… -------------------------------- devm_blk_crypto_profile_init() registers a cleanup handler to run when the associated (platform-) device is being released. For UFS, the crypto private data and pointers are stored as part of the ufs_hba's data structure 'struct ufs_hba::crypto_profile'. This structure is allocated as part of the underlying ufshcd and therefore Scsi_host allocation. During driver release or during error handling in ufshcd_pltfrm_init(), this structure is released as part of ufshcd_dealloc_host() before the (platform-) device associated with the crypto call above is released. Once this device is released, the crypto cleanup code will run, using the just-released 'struct ufs_hba::crypto_profile'. This causes a use-after-free situation: Call trace: kfree+0x60/0x2d8 (P) kvfree+0x44/0x60 blk_crypto_profile_destroy_callback+0x28/0x70 devm_action_release+0x1c/0x30 release_nodes+0x6c/0x108 devres_release_all+0x98/0x100 device_unbind_cleanup+0x20/0x70 really_probe+0x218/0x2d0 In other words, the initialisation code flow is: platform-device probe ufshcd_pltfrm_init() ufshcd_alloc_host() scsi_host_alloc() allocation of struct ufs_hba creation of scsi-host devices devm_blk_crypto_profile_init() devm registration of cleanup handler using platform-device and during error handling of ufshcd_pltfrm_init() or during driver removal: ufshcd_dealloc_host() scsi_host_put() put_device(scsi-host) release of struct ufs_hba put_device(platform-device) crypto cleanup handler To fix this use-after free, change ufshcd_alloc_host() to register a devres action to automatically cleanup the underlying SCSI device on ufshcd destruction, without requiring explicit calls to ufshcd_dealloc_host().

[PATCH OLK-5.10 V1] list: fix a data-race around ep->rdllist
by Zicheng Qu 28 Mar '25

28 Mar '25

From: Kuniyuki Iwashima <kuniyu(a)amazon.co.jp> stable inclusion from stable-v5.15.46 commit 5d5d993f16be15d124be7b8ec71b28ef7b7dc3af category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6RN CVE: CVE-2022-49443 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/comm… -------------------------------- [ Upstream commit d679ae94fdd5d3ab00c35078f5af5f37e068b03d ] ep_poll() first calls ep_events_available() with no lock held and checks if ep->rdllist is empty by list_empty_careful(), which reads rdllist->prev. Thus all accesses to it need some protection to avoid store/load-tearing. Note INIT_LIST_HEAD_RCU() already has the annotation for both prev and next. Commit bf3b9f6372c4 ("epoll: Add busy poll support to epoll with socket fds.") added the first lockless ep_events_available(), and commit c5a282e9635e ("fs/epoll: reduce the scope of wq lock in epoll_wait()") made some ep_events_available() calls lockless and added single call under a lock, finally commit e59d3c64cba6 ("epoll: eliminate unnecessary lock for zero timeout") made the last ep_events_available() lockless.

[PATCH OLK-6.6 1/2] btrfs: do proper folio cleanup when cow_file_range() failed

From: Qu Wenruo <wqu(a)suse.com> stable inclusion from stable-v6.13.2 commit 692cf71173bb41395c855acbbbe197d3aedfa5d4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPBJV CVE: CVE-2024-57976 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 06f364284794f149d2abc167c11d556cf20c954b upstream. [BUG] When testing with COW fixup marked as BUG_ON() (this is involved with the new pin_user_pages*() change, which should not result new out-of-band dirty pages), I hit a crash triggered by the BUG_ON() from hitting COW fixup path. This BUG_ON() happens just after a failed btrfs_run_delalloc_range(): BTRFS error (device dm-2): failed to run delalloc range, root 348 ino 405 folio 65536 submit_bitmap 6-15 start 90112 len 106496: -28 ------------[ cut here ]------------ kernel BUG at fs/btrfs/extent_io.c:1444!

Although the -ENOSPC is already a bug related to our space reservation code, let's just focus on the error handling. For example, we have the following dirty range [0, 64K) of an inode, with 4K sector size and 4K page size: 0 16K 32K 48K 64K |///////////////////////////////////////| |#######################################| Where |///| means page are still dirty, and |###| means the extent io tree has EXTENT_DELALLOC flag. - Enter extent_writepage() for page 0 - Enter btrfs_run_delalloc_range() for range [0, 64K) - Enter cow_file_range() for range [0, 64K) - Function btrfs_reserve_extent() only reserved one 16K extent So we created extent map and ordered extent for range [0, 16K) 0 16K 32K 48K 64K |////////|//////////////////////////////| |<- OE ->|##############################| And range [0, 16K) has its delalloc flag cleared. But since we haven't yet submit any bio, involved 4 pages are still dirty. - Function btrfs_reserve_extent() returns with -ENOSPC Now we have to run error cleanup, which will clear all EXTENT_DELALLOC* flags and clear the dirty flags for the remaining ranges: 0 16K 32K 48K 64K |////////| | | | | Note that range [0, 16K) still has its pages dirty. - Some time later, writeback is triggered again for the range [0, 16K) since the page range still has dirty flags. - btrfs_run_delalloc_range() will do nothing because there is no EXTENT_DELALLOC flag. - extent_writepage_io() finds page 0 has no ordered flag Which falls into the COW fixup path, triggering the BUG_ON(). Unfortunately this error handling bug dates back to the introduction of btrfs. Thankfully with the abuse of COW fixup, at least it won't crash the kernel. [FIX] Instead of immediately unlocking the extent and folios, we keep the extent and folios locked until either erroring out or the whole delalloc range finished. When the whole delalloc range finished without error, we just unlock the whole range with PAGE_SET_ORDERED (and PAGE_UNLOCK for !keep_locked cases), with EXTENT_DELALLOC and EXTENT_LOCKED cleared. And the involved folios will be properly submitted, with their dirty flags cleared during submission. For the error path, it will be a little more complex: - The range with ordered extent allocated (range (1)) We only clear the EXTENT_DELALLOC and EXTENT_LOCKED, as the remaining flags are cleaned up by btrfs_mark_ordered_io_finished()->btrfs_finish_one_ordered(). For folios we finish the IO (clear dirty, start writeback and immediately finish the writeback) and unlock the folios. - The range with reserved extent but no ordered extent (range(2)) - The range we never touched (range(3)) For both range (2) and range(3) the behavior is not changed. Now even if cow_file_range() failed halfway with some successfully reserved extents/ordered extents, we will keep all folios clean, so there will be no future writeback triggered on them.

[PATCH openEuler-1.0-LTS] ath5k: fix OOB in ath5k_eeprom_read_pcal_info_5111
by Peng Zhang 27 Mar '25

27 Mar '25

From: Zekun Shen <bruceshenzk(a)gmail.com> stable inclusion from stable-v4.19.238 commit 25efc5d03455c3839249bc77fce5e29ecb54677e category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP5YP CVE: CVE-2021-47633 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------- [ Upstream commit 564d4eceb97eaf381dd6ef6470b06377bb50c95a ] The bug was found during fuzzing. Stacktrace locates it in ath5k_eeprom_convert_pcal_info_5111. When none of the curve is selected in the loop, idx can go up to AR5K_EEPROM_N_PD_CURVES. The line makes pd out of bound. pd = &chinfo[pier].pd_curves[idx]; There are many OOB writes using pd later in the code. So I added a sanity check for idx. Checks for other loops involving AR5K_EEPROM_N_PD_CURVES are not needed as the loop index is not used outside the loops. The patch is NOT tested with real device. The following is the fuzzing report BUG: KASAN: slab-out-of-bounds in ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] Write of size 1 at addr ffff8880174a4d60 by task modprobe/214 CPU: 0 PID: 214 Comm: modprobe Not tainted 5.6.0 #1 Call Trace: dump_stack+0x76/0xa0 print_address_description.constprop.0+0x16/0x200 ? ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] ? ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] __kasan_report.cold+0x37/0x7c ? ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] kasan_report+0xe/0x20 ath5k_eeprom_read_pcal_info_5111+0x126a/0x1390 [ath5k] ? apic_timer_interrupt+0xa/0x20 ? ath5k_eeprom_init_11a_pcal_freq+0xbc0/0xbc0 [ath5k] ? ath5k_pci_eeprom_read+0x228/0x3c0 [ath5k] ath5k_eeprom_init+0x2513/0x6290 [ath5k] ? ath5k_eeprom_init_11a_pcal_freq+0xbc0/0xbc0 [ath5k] ? usleep_range+0xb8/0x100 ? apic_timer_interrupt+0xa/0x20 ? ath5k_eeprom_read_pcal_info_2413+0x2f20/0x2f20 [ath5k] ath5k_hw_init+0xb60/0x1970 [ath5k] ath5k_init_ah+0x6fe/0x2530 [ath5k] ? kasprintf+0xa6/0xe0 ? ath5k_stop+0x140/0x140 [ath5k] ? _dev_notice+0xf6/0xf6 ? apic_timer_interrupt+0xa/0x20 ath5k_pci_probe.cold+0x29a/0x3d6 [ath5k] ? ath5k_pci_eeprom_read+0x3c0/0x3c0 [ath5k] ? mutex_lock+0x89/0xd0 ? ath5k_pci_eeprom_read+0x3c0/0x3c0 [ath5k] local_pci_probe+0xd3/0x160 pci_device_probe+0x23f/0x3e0 ? pci_device_remove+0x280/0x280 ? pci_device_remove+0x280/0x280 really_probe+0x209/0x5d0 Reported-by: Brendan Dolan-Gavitt <brendandg(a)nyu.edu> Signed-off-by: Zekun Shen <bruceshenzk(a)gmail.com> Signed-off-by: Kalle Valo <quic_kvalo(a)quicinc.com> Link: https://lore.kernel.org/r/YckvDdj3mtCkDRIt@a-10-27-26-18.dynapool.vpn.nyu.e… Signed-off-by: Sasha Levin <sashal(a)kernel.org> Signed-off-by: ZhangPeng <zhangpeng362(a)huawei.com> --- drivers/net/wireless/ath/ath5k/eeprom.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/net/wireless/ath/ath5k/eeprom.c b/drivers/net/wireless/ath/ath5k/eeprom.c index 94d34ee02265..01163b333945 100644 --- a/drivers/net/wireless/ath/ath5k/eeprom.c +++ b/drivers/net/wireless/ath/ath5k/eeprom.c @@ -746,6 +746,9 @@ ath5k_eeprom_convert_pcal_info_5111(struct ath5k_hw *ah, int mode, } } + if (idx == AR5K_EEPROM_N_PD_CURVES) + goto err_out; + ee->ee_pd_gains[mode] = 1; pd = &chinfo[pier].pd_curves[idx]; -- 2.25.1

[PATCH OLK-6.6] ASoC: soc-pcm: don't use soc_pcm_ret() on .prepare callback
by Qi Xi 27 Mar '25

27 Mar '25

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> mainline inclusion from mainline-v6.14-rc1 commit 301c26a018acb94dd537a4418cefa0f654500c6f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRED3 CVE: CVE-2024-58077 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port" log severity") ignores -EINVAL error message on common soc_pcm_ret(). It is used from many functions, ignoring -EINVAL is over-kill. The reason why -EINVAL was ignored was it really should only be used upon invalid parameters coming from userspace and in that case we don't want to log an error since we do not want to give userspace a way to do a denial-of-service attack on the syslog / diskspace. So don't use soc_pcm_ret() on .prepare callback is better idea.

[PATCH openEuler-1.0-LTS] media: pvrusb2: fix array-index-out-of-bounds in pvr2_i2c_core_init
by Gu Bowen 26 Mar '25

26 Mar '25

From: Pavel Skripkin <paskripkin(a)gmail.com> stable inclusion from stable-v4.19.247 commit a3660e06675bccec4bf149c7229ea1d491ba10d7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6VC CVE: CVE-2022-49478 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 471bec68457aaf981add77b4f590d65dd7da1059 ] Syzbot reported that -1 is used as array index. The problem was in missing validation check. hdw->unit_number is initialized with -1 and then if init table walk fails this value remains unchanged. Since code blindly uses this member for array indexing adding sanity check is the easiest fix for that. hdw->workpoll initialization moved upper to prevent warning in __flush_work.

[PATCH openEuler-1.0-LTS] media: uvcvideo: Remove dangling pointers
by Zhao Yipeng 26 Mar '25

26 Mar '25

From: Ricardo Ribalda <ribalda(a)chromium.org> mainline inclusion from mainline-v6.14-rc1 commit 221cd51efe4565501a3dbf04cc011b537dcce7fb category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC8W CVE: CVE-2024-58002 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/comm… -------------------------------- When an async control is written, we copy a pointer to the file handle that started the operation. That pointer will be used when the device is done. Which could be anytime in the future. If the user closes that file descriptor, its structure will be freed, and there will be one dangling pointer per pending async control, that the driver will try to use. Clean all the dangling pointers during release(). To avoid adding a performance penalty in the most common case (no async operation), a counter has been introduced with some logic to make sure that it is properly handled.

[PATCH OLK-6.6] nilfs2: do not force clear folio if buffer is referenced
by Liu Chuang 26 Mar '25

26 Mar '25

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> mainline inclusion from mainline-v6.14-rc1 commit ca76bb226bf47ff04c782cacbd299f12ddee1ec1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPBK0 CVE: CVE-2025-21722 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------- Patch series "nilfs2: protect busy buffer heads from being force-cleared". This series fixes the buffer head state inconsistency issues reported by syzbot that occurs when the filesystem is corrupted and falls back to read-only, and the associated buffer head use-after-free issue. This patch (of 2): Syzbot has reported that after nilfs2 detects filesystem corruption and falls back to read-only, inconsistencies in the buffer state may occur. One of the inconsistencies is that when nilfs2 calls mark_buffer_dirty() to set a data or metadata buffer as dirty, but it detects that the buffer is not in the uptodate state: WARNING: CPU: 0 PID: 6049 at fs/buffer.c:1177 mark_buffer_dirty+0x2e5/0x520 fs/buffer.c:1177 ...

[PATCH OLK-6.6] ata: libata-sff: Ensure that we cannot write outside the allocated buffer
by Zheng Qixing 26 Mar '25

26 Mar '25

From: Niklas Cassel <cassel(a)kernel.org> stable inclusion from stable-v6.6.78 commit d5e6e3000309359eae2a17117aa6e3c44897bf6c category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBPC5G CVE: CVE-2025-21738 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------ commit 6e74e53b34b6dec5a50e1404e2680852ec6768d2 upstream. reveliofuzzing reported that a SCSI_IOCTL_SEND_COMMAND ioctl with out_len set to 0xd42, SCSI command set to ATA_16 PASS-THROUGH, ATA command set to ATA_NOP, and protocol set to ATA_PROT_PIO, can cause ata_pio_sector() to write outside the allocated buffer, overwriting random memory. While a ATA device is supposed to abort a ATA_NOP command, there does seem to be a bug either in libata-sff or QEMU, where either this status is not set, or the status is cleared before read by ata_sff_hsm_move(). Anyway, that is most likely a separate bug. Looking at __atapi_pio_bytes(), it already has a safety check to ensure that __atapi_pio_bytes() cannot write outside the allocated buffer. Add a similar check to ata_pio_sector(), such that also ata_pio_sector() cannot write outside the allocated buffer.

[PATCH OLK-6.6] block: don't revert iter for -EIOCBQUEUED

From: Jens Axboe <axboe(a)kernel.dk> stable inclusion from stable-v6.6.78 commit 84671b0630ccb46ae9f1f99a45c7d63ffcd6a474 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRECT CVE: CVE-2025-21832 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------ commit b13ee668e8280ca5b07f8ce2846b9957a8a10853 upstream. blkdev_read_iter() has a few odd checks, like gating the position and count adjustment on whether or not the result is bigger-than-or-equal to zero (where bigger than makes more sense), and not checking the return value of blkdev_direct_IO() before doing an iov_iter_revert(). The latter can lead to attempting to revert with a negative value, which when passed to iov_iter_revert() as an unsigned value will lead to throwing a WARN_ON() because unroll is bigger than MAX_RW_COUNT. Be sane and don't revert for -EIOCBQUEUED, like what is done in other spots.
