[PATCH OLK-6.6] netfilter: nft_ct: add seqadj extension for natted connections

commit 90918e3b6404c2a37837b8f11692471b4c512de2
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/11571
CVE: CVE-2025-68206
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
Sequence adjustment may be required for FTP traffic with PASV/EPSV modes.
due to need to re-write packet payload (IP, port) on the ftp control
connection. This can require changes to the TCP length and expected
seq / ack_seq.
The easiest way to reproduce this issue is with PASV mode.
Example ruleset:
table inet ftp_nat {
ct helper ftp_helper {
type "ftp" protocol tcp
l3proto inet
}
chain prerouting {
type filter hook prerouting priority 0; policy accept;
tcp dport 21 ct state new ct helper set "ftp_helper"
}
}
table ip nat {
chain prerouting {
type nat hook prerouting priority -100; policy accept;
tcp dport 21 dnat ip prefix to ip daddr map {
192.168.100.1 : 192.168.13.2/32 }
}
chain postrouting {
type nat hook postrouting priority 100 ; policy accept;
tcp sport 21 snat ip prefix to ip saddr map {
192.168.13.2 : 192.168.100.1/32 }
}
}
Note that the ftp helper gets assigned *after* the dnat setup.
The inverse (nat after helper assign) is handled by an existing
check in nf_nat_setup_info() and will not show the problem.
Topoloy:
+-------------------+ +----------------------------------+
| FTP: 192.168.13.2 | <-> | NAT: 192.168.13.3, 192.168.100.1 |

Fix this by adding the required extension when a conntrack helper is assigned
to a connection that has a nat binding.

category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/7786
CVE: CVE-2025-40083
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
To prevent a potential crash in agg_dequeue (net/sched/sch_qfq.c)
when cl->qdisc->ops->peek(cl->qdisc) returns NULL, we check the return
value before using it, similar to the existing approach in sch_hfsc.c.
To avoid code duplication, the following changes are made:
1. Changed qdisc_warn_nonwc(include/net/pkt_sched.h) into a static
inline function.
2. Moved qdisc_peek_len from net/sched/sch_hfsc.c to
include/net/pkt_sched.h so that sch_qfq can reuse it.
3. Applied qdisc_peek_len in agg_dequeue to avoid crashing.

category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/12429
CVE: CVE-2025-38591
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
The following BPF program, simplified from a syzkaller repro, causes a
kernel warning:
r0 = *(u8 *)(r1 + 169);
exit;
With pointer field sk being at offset 168 in __sk_buff. This access is
detected as a narrower read in bpf_skb_is_valid_access because it
doesn't match offsetof(struct __sk_buff, sk). It is therefore allowed
and later proceeds to bpf_convert_ctx_access. Note that for the
"is_narrower_load" case in the convert_ctx_accesses(), the insn->off
is aligned, so the cnt may not be 0 because it matches the
offsetof(struct __sk_buff, sk) in the bpf_convert_ctx_access. However,
the target_size stays 0 and the verifier errors with a kernel warning:
verifier bug: error during ctx access conversion(1)
This patch fixes that to return a proper "invalid bpf_context access
off=X size=Y" error on the load instruction.
The same issue affects multiple other fields in context structures that
allow narrow access. Some other non-affected fields (for sk_msg,
sk_lookup, and sockopt) were also changed to use bpf_ctx_range_ptr for
consistency.
Note this syzkaller crash was reported in the "Closes" link below, which
used to be about a different bug, fixed in
commit fce7bd8e385a ("bpf/verifier: Handle BPF_LOAD_ACQ instructions
in insn_def_regno()"). Because syzbot somehow confused the two bugs,
the new crash and repro didn't get reported to the mailing list.
Fixes: f96da09473b52 ("bpf: simplify narrower ctx access")
Fixes: 0df1a55afa832 ("bpf: Warn on internal verifier errors")

commit 2ed25aa7f7711f508b6120e336f05cd9d49943c0
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/9417
CVE: CVE-2025-38373
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
The issue arises when kzalloc() is invoked while holding umem_mutex or
any other lock acquired under umem_mutex. This is problematic because
kzalloc() can trigger fs_reclaim_aqcuire(), which may, in turn, invoke
mmu_notifier_invalidate_range_start(). This function can lead to
mlx5_ib_invalidate_range(), which attempts to acquire umem_mutex again,
resulting in a deadlock.
The problematic flow:
CPU0 | CPU1
---------------------------------------|------------------------------------------------
mlx5_ib_dereg_mr() |
→ revoke_mr() |
→ mutex_lock(&umem_odp->umem_mutex) |
| mlx5_mkey_cache_init()
| → mutex_lock(&dev->cache.rb_lock)
| → mlx5r_cache_create_ent_locked()
| → kzalloc(GFP_KERNEL)
| → fs_reclaim()
| → mmu_notifier_invalidate_range_start()
| → mlx5_ib_invalidate_range()
| → mutex_lock(&umem_odp->umem_mutex)
→ cache_ent_find_and_store() |
→ mutex_lock(&dev->cache.rb_lock) |
Additionally, when kzalloc() is called from within
cache_ent_find_and_store(), we encounter the same deadlock due to
re-acquisition of umem_mutex.
Solve by releasing umem_mutex in dereg_mr() after umr_revoke_mr()
and before acquiring rb_lock. This ensures that we don't hold
umem_mutex while performing memory allocations that could trigger
the reclaim path.
This change prevents the deadlock by ensuring proper lock ordering and
avoiding holding locks during memory allocation operations that could
trigger the reclaim path.
The following lockdep warning demonstrates the deadlock:
python3/20557 is trying to acquire lock:
ffff888387542128 (&umem_odp->umem_mutex){+.+.}-{4:4}, at:

--------------------------------
[ Upstream commit 56094ad3eaa21e6621396cc33811d8f72847a834 ]
When user calls open_by_handle_at() on some inode that is not cached, we
will create disconnected dentry for it. If such dentry is a directory,
exportfs_decode_fh_raw() will then try to connect this dentry to the
dentry tree through reconnect_path(). It may happen for various reasons
(such as corrupted fs or race with rename) that the call to
lookup_one_unlocked() in reconnect_one() will fail to find the dentry we
are trying to reconnect and instead create a new dentry under the
parent. Now this dentry will not be marked as disconnected although the
parent still may well be disconnected (at least in case this
inconsistency happened because the fs is corrupted and .. doesn't point
to the real parent directory). This creates inconsistency in
disconnected flags but AFAICS it was mostly harmless. At least until
commit f1ee616214cb ("VFS: don't keep disconnected dentries on d_anon")
which removed adding of most disconnected dentries to sb->s_anon list.
Thus after this commit cleanup of disconnected dentries implicitely
relies on the fact that dput() will immediately reclaim such dentries.
However when some leaf dentry isn't marked as disconnected, as in the
scenario described above, the reclaim doesn't happen and the dentries
are "leaked". Memory reclaim can eventually reclaim them but otherwise
they stay in memory and if umount comes first, we hit infamous "Busy
inodes after unmount" bug. Make sure all dentries created under a
disconnected parent are marked as disconnected as well.

--------------------------------
commit 9eb00b5f5697bd56baa3222c7a1426fa15bacfb5 upstream.
Delete the attempt to progress the queue when checking if fence is
signaled. This avoids deadlock.
dma-fence_ops::signaled can be called with the fence lock in unknown
state. For radeon, the fence lock is also the wait queue lock. This can
cause a self deadlock when signaled() tries to make forward progress on
the wait queue. But advancing the queue is unneeded because incorrectly
returning false from signaled() is perfectly acceptable.

[ Upstream commit 2c5f4a53476e3cab70adc77b38942c066bd2c17c ]
Function new_inode() returns a new inode with inode->i_mapping->gfp_mask
set to GFP_HIGHUSER_MOVABLE. This value includes the __GFP_FS flag, so
allocations in that address space can recurse into filesystem memory
reclaim. We don't want that to happen because it can consume a
significant amount of stack memory.
Worse than that is that it can also deadlock: for example, in several
places, gfs2_unstuff_dinode() is called inside filesystem transactions.
This calls filemap_grab_folio(), which can allocate a new folio, which
can trigger memory reclaim. If memory reclaim recurses into the
filesystem and starts another transaction, a deadlock will ensue.
To fix these kinds of problems, prevent memory reclaim from recursing
into filesystem code by making sure that the gfp_mask of inode address
spaces doesn't include __GFP_FS.
The "meta" and resource group address spaces were already using GFP_NOFS
as their gfp_mask (which doesn't include __GFP_FS). The default value
of GFP_HIGHUSER_MOVABLE is less restrictive than GFP_NOFS, though. To
avoid being overly limiting, use the default value and only knock off
the __GFP_FS flag. I'm not sure if this will actually make a
difference, but it also shouldn't hurt.
This patch is loosely based on commit ad22c7a043c2 ("xfs: prevent stack
overflows from page cache allocation").
Fixes xfstest generic/273.

[PATCH OLK-6.6] KVM: SVM: Don't skip unrelated instruction if INT3/INTO is replaced

commit 87cc1622c88a4888959d64fa1fc9ba1e264aa3d4
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/11544
CVE: CVE-2025-68259
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 4da3768e1820cf15cced390242d8789aed34f54d upstream.
When re-injecting a soft interrupt from an INT3, INT0, or (select) INTn
instruction, discard the exception and retry the instruction if the code
stream is changed (e.g. by a different vCPU) between when the CPU
executes the instruction and when KVM decodes the instruction to get the
next RIP.
As effectively predicted by commit 6ef88d6e36c2 ("KVM: SVM: Re-inject
INT3/INTO instead of retrying the instruction"), failure to verify that
the correct INTn instruction was decoded can effectively clobber guest
state due to decoding the wrong instruction and thus specifying the
wrong next RIP.
The bug most often manifests as "Oops: int3" panics on static branch
checks in Linux guests. Enabling or disabling a static branch in Linux
uses the kernel's "text poke" code patching mechanism. To modify code
while other CPUs may be executing that code, Linux (temporarily)
replaces the first byte of the original instruction with an int3 (opcode
0xcc), then patches in the new code stream except for the first byte,
and finally replaces the int3 with the first byte of the new code
stream. If a CPU hits the int3, i.e. executes the code while it's being
modified, then the guest kernel must look up the RIP to determine how to
handle the #BP, e.g. by emulating the new instruction. If the RIP is
incorrect, then this lookup fails and the guest kernel panics.
The bug reproduces almost instantly by hacking the guest kernel to
repeatedly check a static branch[1] while running a drgn script[2] on
the host to constantly swap out the memory containing the guest's TSS.

--------------------------------
commit 4002ee98c022d671ecc1e4a84029e9ae7d8a5603 upstream.
While the API contract in docs doesn't specify it explicitly, the
generic implementation of the get_function_name() callback from struct
pinmux_ops - pinmux_generic_get_function_name() - can fail and return
NULL. This is already checked in pinmux_check_ops() so add a similar
check in pinmux_func_name_to_selector() instead of passing the returned
pointer right down to strcmp() where the NULL can get dereferenced. This
is normal operation when adding new pinfunctions.

--------------------------------
[ Upstream commit 1e56310b40fd2e7e0b9493da9ff488af145bdd0c ]
The AMD IOMMU host page table implementation supports dynamic page table levels
(up to 6 levels), starting with a 3-level configuration that expands based on
IOVA address. The kernel maintains a root pointer and current page table level
to enable proper page table walks in alloc_pte()/fetch_pte() operations.
The IOMMU IOVA allocator initially starts with 32-bit address and onces its
exhuasted it switches to 64-bit address (max address is determined based
on IOMMU and device DMA capability). To support larger IOVA, AMD IOMMU
driver increases page table level.
But in unmap path (iommu_v1_unmap_pages()), fetch_pte() reads
pgtable->[root/mode] without lock. So its possible that in exteme corner case,
when increase_address_space() is updating pgtable->[root/mode], fetch_pte()
reads wrong page table level (pgtable->mode). It does compare the value with
level encoded in page table and returns NULL. This will result is
iommu_unmap ops to fail and upper layer may retry/log WARN_ON.
CPU 0 CPU 1
------ ------
map pages unmap pages
alloc_pte() -> increase_address_space() iommu_v1_unmap_pages() -> fetch_pte()
pgtable->root = pte (new root value)
READ pgtable->[mode/root]
Reads new root, old mode
Updates mode (pgtable->mode += 1)
Since Page table level updates are infrequent and already synchronized with a
spinlock, implement seqcount to enable lock-free read operations on the read path.

[PATCH v1 openEuler-26.09] Add copy to/from/in user with vectorization support

bugzilla: https://atomgit.com/openeuler/kernel/issues/8445
-------------------------------------------------
1. This implementation uses st1/ld1 4-vector instructions which allow to copy 64 bytes at once
2. Copy code is used only if size of data block to copy is more than 128 bytes
4. To use this functionality you need to set configuration switch CONFIG_USE_VECTORIZED_COPY=y
5. Code can be used on any ARMv8 variant
6. In kernel copy functions like memcpy are not supported now, but can be enabled in future
7. For now we use lightweght version of register context saving/restoration (4-registers)
We introduce support of vectorization for copy_from/to/in_user functions. Nowadays it
works in parallel with original FPSIMD/SVE vectorization and doesn't affect it anyhow.
We have special flag in task struct - TIF_KERNEL_FPSIMD, that set if currently we use
lightweight vectorization in kernel. Task struct has been updated by two fields:
user space fpsimd state and kernel fpsimd state. User space fpsimd state used by
kernel_fpsimd_begin(), kernel_fpsimd_end() functions that wrap lightweight FPSIMD
contexts usage in kernel space. Kernel fpsimd state is used to manage threads switch.
Now there is no support of nested calls of kernel_neon_begin()/kernel_fpsimd_begin()
and there is no plans to support this in future. This is not necessary.
We save lightweight FPSIMD context in kernel_fpsimd_begin(), and restore it in
/kernel_fpsimd_end(). On thread switch we preserve kernel FPSIMD context and restore
user space one if any. This prevens curruption of user space FPSIMD state. Before
switching to the next thread we restore it's kernel FPSIMD context if any.
It is allowed to use FPSIMD in bottom halves, due to in case of BH preemption we check
TIF_KERNEL_FPSIMD flag and save/restore contexts.
Context management if quite lightweight and executed only in case of TIF_KERNEL_FPSIMD
flag is set.
To enable this feature, you need to manually modify one of the
appropriate entries:
/proc/sys/vm/copy_from_user_threshold
/proc/sys/vm/copy_in_user_threshold
/proc/sys/vm/copy_to_user_threshold
Allowed values are following:
-1 - feature enabled
0 - feature always enabled
n (n >0) - feature enabled, if copied size is greater than n KB.
P.S.:
What I am personally don't like in current approach:
1. Additional fields and flag in task struct look quite ugly
2. No way to configure the size of chunk to copy using FPSIMD from user space
3. FPSIMD-based memory movement is not generic, need to enable for memmove(),
memcpy() and friends in future.

[PATCH v1 openEuler-25.03] Add copy to/from/in user with vectorization support
by Nikita Panov 28 Jan '26
by Nikita Panov 28 Jan '26
28 Jan '26
From: Artem Kuzin <artem.kuzin(a)huawei.com>
kunpeng inclusion
category: feature
bugzilla: https://atomgit.com/openeuler/kernel/issues/8445
-------------------------------------------------
1. This implementation uses st1/ld1 4-vector instructions which allow to copy 64 bytes at once
2. Copy code is used only if size of data block to copy is more than 128 bytes
4. To use this functionality you need to set configuration switch CONFIG_USE_VECTORIZED_COPY=y
5. Code can be used on any ARMv8 variant
6. In kernel copy functions like memcpy are not supported now, but can be enabled in future
7. For now we use lightweght version of register context saving/restoration (4-registers)
We introduce support of vectorization for copy_from/to/in_user functions. Nowadays it
works in parallel with original FPSIMD/SVE vectorization and doesn't affect it anyhow.
We have special flag in task struct - TIF_KERNEL_FPSIMD, that set if currently we use
lightweight vectorization in kernel. Task struct has been updated by two fields:
user space fpsimd state and kernel fpsimd state. User space fpsimd state used by
kernel_fpsimd_begin(), kernel_fpsimd_end() functions that wrap lightweight FPSIMD
contexts usage in kernel space. Kernel fpsimd state is used to manage threads switch.
Now there is no support of nested calls of kernel_neon_begin()/kernel_fpsimd_begin()
and there is no plans to support this in future. This is not necessary.
We save lightweight FPSIMD context in kernel_fpsimd_begin(), and restore it in
/kernel_fpsimd_end(). On thread switch we preserve kernel FPSIMD context and restore
user space one if any. This prevens curruption of user space FPSIMD state. Before
switching to the next thread we restore it's kernel FPSIMD context if any.
It is allowed to use FPSIMD in bottom halves, due to in case of BH preemption we check
TIF_KERNEL_FPSIMD flag and save/restore contexts.
Context management if quite lightweight and executed only in case of TIF_KERNEL_FPSIMD
flag is set.
To enable this feature, you need to manually modify one of the
appropriate entries:
/proc/sys/vm/copy_from_user_threshold
/proc/sys/vm/copy_in_user_threshold
/proc/sys/vm/copy_to_user_threshold
Allowed values are following:
-1 - feature enabled
0 - feature always enabled
n (n >0) - feature enabled, if copied size is greater than n KB.
P.S.:
What I am personally don't like in current approach:
1. Additional fields and flag in task struct look quite ugly
2. No way to configure the size of chunk to copy using FPSIMD from user space
3. FPSIMD-based memory movement is not generic, need to enable for memmove(),
memcpy() and friends in future.

From: Artem Kuzin <artem.kuzin(a)huawei.com>
kunpeng inclusion
category: feature
bugzilla: https://atomgit.com/openeuler/kernel/issues/8445
-------------------------------------------------
1. This implementation uses st1/ld1 4-vector instructions which allow to copy 64 bytes at once
2. Copy code is used only if size of data block to copy is more than 128 bytes
4. To use this functionality you need to set configuration switch CONFIG_USE_VECTORIZED_COPY=y
5. Code can be used on any ARMv8 variant
6. In kernel copy functions like memcpy are not supported now, but can be enabled in future
7. For now we use lightweght version of register context saving/restoration (4-registers)
We introduce support of vectorization for copy_from/to/in_user functions. Nowadays it
works in parallel with original FPSIMD/SVE vectorization and doesn't affect it anyhow.
We have special flag in task struct - TIF_KERNEL_FPSIMD, that set if currently we use
lightweight vectorization in kernel. Task struct has been updated by two fields:
user space fpsimd state and kernel fpsimd state. User space fpsimd state used by
kernel_fpsimd_begin(), kernel_fpsimd_end() functions that wrap lightweight FPSIMD
contexts usage in kernel space. Kernel fpsimd state is used to manage threads switch.
Now there is no support of nested calls of kernel_neon_begin()/kernel_fpsimd_begin()
and there is no plans to support this in future. This is not necessary.
We save lightweight FPSIMD context in kernel_fpsimd_begin(), and restore it in
/kernel_fpsimd_end(). On thread switch we preserve kernel FPSIMD context and restore
user space one if any. This prevens curruption of user space FPSIMD state. Before
switching to the next thread we restore it's kernel FPSIMD context if any.
It is allowed to use FPSIMD in bottom halves, due to in case of BH preemption we check
TIF_KERNEL_FPSIMD flag and save/restore contexts.
Context management if quite lightweight and executed only in case of TIF_KERNEL_FPSIMD
flag is set.
To enable this feature, you need to manually modify one of the
appropriate entries:
/proc/sys/vm/copy_from_user_threshold
/proc/sys/vm/copy_in_user_threshold
/proc/sys/vm/copy_to_user_threshold
Allowed values are following:
-1 - feature enabled
0 - feature always enabled
n (n >0) - feature enabled, if copied size is greater than n KB.
P.S.:
What I am personally don't like in current approach:
1. Additional fields and flag in task struct look quite ugly
2. No way to configure the size of chunk to copy using FPSIMD from user space
3. FPSIMD-based memory movement is not generic, need to enable for memmove(),
memcpy() and friends in future.

From: Artem Kuzin <artem.kuzin(a)huawei.com>
kunpeng inclusion
category: feature
bugzilla: https://atomgit.com/openeuler/kernel/issues/8445
-------------------------------------------------
1. This implementation uses st1/ld1 4-vector instructions which allow to copy 64 bytes at once
2. Copy code is used only if size of data block to copy is more than 128 bytes
4. To use this functionality you need to set configuration switch CONFIG_USE_VECTORIZED_COPY=y
5. Code can be used on any ARMv8 variant
6. In kernel copy functions like memcpy are not supported now, but can be enabled in future
7. For now we use lightweght version of register context saving/restoration (4-registers)
We introduce support of vectorization for copy_from/to/in_user functions. Nowadays it
works in parallel with original FPSIMD/SVE vectorization and doesn't affect it anyhow.
We have special flag in task struct - TIF_KERNEL_FPSIMD, that set if currently we use
lightweight vectorization in kernel. Task struct has been updated by two fields:
user space fpsimd state and kernel fpsimd state. User space fpsimd state used by
kernel_fpsimd_begin(), kernel_fpsimd_end() functions that wrap lightweight FPSIMD
contexts usage in kernel space. Kernel fpsimd state is used to manage threads switch.
Now there is no support of nested calls of kernel_neon_begin()/kernel_fpsimd_begin()
and there is no plans to support this in future. This is not necessary.
We save lightweight FPSIMD context in kernel_fpsimd_begin(), and restore it in
/kernel_fpsimd_end(). On thread switch we preserve kernel FPSIMD context and restore
user space one if any. This prevens curruption of user space FPSIMD state. Before
switching to the next thread we restore it's kernel FPSIMD context if any.
It is allowed to use FPSIMD in bottom halves, due to in case of BH preemption we check
TIF_KERNEL_FPSIMD flag and save/restore contexts.
Context management if quite lightweight and executed only in case of TIF_KERNEL_FPSIMD
flag is set.
To enable this feature, you need to manually modify one of the
appropriate entries:
/proc/sys/vm/copy_from_user_threshold
/proc/sys/vm/copy_in_user_threshold
/proc/sys/vm/copy_to_user_threshold
Allowed values are following:
-1 - feature enabled
0 - feature always enabled
n (n >0) - feature enabled, if copied size is greater than n KB.
P.S.:
What I am personally don't like in current approach:
1. Additional fields and flag in task struct look quite ugly
2. No way to configure the size of chunk to copy using FPSIMD from user space
3. FPSIMD-based memory movement is not generic, need to enable for memmove(),
memcpy() and friends in future.

From: Artem Kuzin <artem.kuzin(a)huawei.com>
kunpeng inclusion
category: feature
bugzilla: https://atomgit.com/openeuler/kernel/issues/8445
-------------------------------------------------
1. This implementation uses st1/ld1 4-vector instructions which allow to copy 64 bytes at once
2. Copy code is used only if size of data block to copy is more than 128 bytes
4. To use this functionality you need to set configuration switch CONFIG_USE_VECTORIZED_COPY=y
5. Code can be used on any ARMv8 variant
6. In kernel copy functions like memcpy are not supported now, but can be enabled in future
7. For now we use lightweght version of register context saving/restoration (4-registers)
We introduce support of vectorization for copy_from/to/in_user functions. Nowadays it
works in parallel with original FPSIMD/SVE vectorization and doesn't affect it anyhow.
We have special flag in task struct - TIF_KERNEL_FPSIMD, that set if currently we use
lightweight vectorization in kernel. Task struct has been updated by two fields:
user space fpsimd state and kernel fpsimd state. User space fpsimd state used by
kernel_fpsimd_begin(), kernel_fpsimd_end() functions that wrap lightweight FPSIMD
contexts usage in kernel space. Kernel fpsimd state is used to manage threads switch.
Now there is no support of nested calls of kernel_neon_begin()/kernel_fpsimd_begin()
and there is no plans to support this in future. This is not necessary.
We save lightweight FPSIMD context in kernel_fpsimd_begin(), and restore it in
/kernel_fpsimd_end(). On thread switch we preserve kernel FPSIMD context and restore
user space one if any. This prevens curruption of user space FPSIMD state. Before
switching to the next thread we restore it's kernel FPSIMD context if any.
It is allowed to use FPSIMD in bottom halves, due to in case of BH preemption we check
TIF_KERNEL_FPSIMD flag and save/restore contexts.
Context management if quite lightweight and executed only in case of TIF_KERNEL_FPSIMD
flag is set.
To enable this feature, you need to manually modify one of the
appropriate entries:
/proc/sys/vm/copy_from_user_threshold
/proc/sys/vm/copy_in_user_threshold
/proc/sys/vm/copy_to_user_threshold
Allowed values are following:
-1 - feature enabled
0 - feature always enabled
n (n >0) - feature enabled, if copied size is greater than n KB.
P.S.:
What I am personally don't like in current approach:
1. Additional fields and flag in task struct look quite ugly
2. No way to configure the size of chunk to copy using FPSIMD from user space
3. FPSIMD-based memory movement is not generic, need to enable for memmove(),
memcpy() and friends in future.

From: Artem Kuzin <artem.kuzin(a)huawei.com>

category: feature
bugzilla: https://atomgit.com/openeuler/kernel/issues/8445
-------------------------------------------------
1. This implementation uses st1/ld1 4-vector instructions which allow to copy 64 bytes at once
2. Copy code is used only if size of data block to copy is more than 128 bytes
4. To use this functionality you need to set configuration switch CONFIG_USE_VECTORIZED_COPY=y
5. Code can be used on any ARMv8 variant
6. In kernel copy functions like memcpy are not supported now, but can be enabled in future
7. For now we use lightweght version of register context saving/restoration (4-registers)
We introduce support of vectorization for copy_from/to/in_user functions. Nowadays it
works in parallel with original FPSIMD/SVE vectorization and doesn't affect it anyhow.
We have special flag in task struct - TIF_KERNEL_FPSIMD, that set if currently we use
lightweight vectorization in kernel. Task struct has been updated by two fields:
user space fpsimd state and kernel fpsimd state. User space fpsimd state used by
kernel_fpsimd_begin(), kernel_fpsimd_end() functions that wrap lightweight FPSIMD
contexts usage in kernel space. Kernel fpsimd state is used to manage threads switch.
Now there is no support of nested calls of kernel_neon_begin()/kernel_fpsimd_begin()
and there is no plans to support this in future. This is not necessary.
We save lightweight FPSIMD context in kernel_fpsimd_begin(), and restore it in
/kernel_fpsimd_end(). On thread switch we preserve kernel FPSIMD context and restore
user space one if any. This prevens curruption of user space FPSIMD state. Before
switching to the next thread we restore it's kernel FPSIMD context if any.
It is allowed to use FPSIMD in bottom halves, due to in case of BH preemption we check
TIF_KERNEL_FPSIMD flag and save/restore contexts.
Context management if quite lightweight and executed only in case of TIF_KERNEL_FPSIMD
flag is set.
To enable this feature, you need to manually modify one of the
appropriate entries:
/proc/sys/vm/copy_from_user_threshold
/proc/sys/vm/copy_in_user_threshold
/proc/sys/vm/copy_to_user_threshold
Allowed values are following:
-1 - feature enabled
0 - feature always enabled
n (n >0) - feature enabled, if copied size is greater than n KB.
P.S.:
What I am personally don't like in current approach:
1. Additional fields and flag in task struct look quite ugly
2. No way to configure the size of chunk to copy using FPSIMD from user space
3. FPSIMD-based memory movement is not generic, need to enable for memmove(),
memcpy() and friends in future.

----------------------------------------------------------------------
A bitmap inconsistency issue was observed during stress tests under
mixed huge-page workloads. Ext4 reported multiple e4b bitmap check
failures like:
ext4_mb_complex_scan_group:2508: group 350, 8179 free clusters as
per group info. But got 8192 blocks
Analysis and experimentation confirmed that the issue is caused by a
race condition between page migration and bitmap modification. Although
this timing window is extremely narrow, it is still hit in practice:
folio_lock ext4_mb_load_buddy
__migrate_folio
check ref count
folio_mc_copy __filemap_get_folio
folio_try_get(folio)
......
mb_mark_used
ext4_mb_unload_buddy
__folio_migrate_mapping
folio_ref_freeze
folio_unlock
The root cause of this issue is that the fast path of load_buddy only
increments the folio's reference count, which is insufficient to prevent
concurrent folio migration. We observed that the folio migration process
acquires the folio lock. Therefore, we can determine whether to take the
fast path in load_buddy by checking the lock status. If the folio is
locked, we opt for the slow path (which acquires the lock) to close this
concurrency window.
Additionally, this change addresses the following issues:
When the DOUBLE_CHECK macro is enabled to inspect bitmap-related
issues, the following error may be triggered:
corruption in group 324 at byte 784(6272): f in copy != ff on
disk/prealloc
Analysis reveals that this is a false positive. There is a specific race
window where the bitmap and the group descriptor become momentarily
inconsistent, leading to this error report:
ext4_mb_load_buddy ext4_mb_load_buddy
__filemap_get_folio(create|lock)
folio_lock
ext4_mb_init_cache
folio_mark_uptodate
__filemap_get_folio(no lock)
......
mb_mark_used
mb_mark_used_double
mb_cmp_bitmaps
mb_set_bits(e4b->bd_bitmap)
folio_unlock
The original logic assumed that since mb_cmp_bitmaps is called when the
bitmap is newly loaded from disk, the folio lock would be sufficient to
prevent concurrent access. However, this overlooks a specific race
condition: if another process attempts to load buddy and finds the folio
is already in an uptodate state, it will immediately begin using it without
holding folio lock.

[PATCH OLK-6.6] udp: Deal with race between UDP socket address change and rehash
by Zhang Changzhong 28 Jan '26

commit a502ea6fa94b1f7be72a24bcf9e3f5f6b7e6e90c
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/10960
CVE: CVE-2024-57974
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
-------------------------------------------------
If a UDP socket changes its local address while it's receiving
datagrams, as a result of connect(), there is a period during which
a lookup operation might fail to find it, after the address is changed
but before the secondary hash (port and address) and the four-tuple
hash (local and remote ports and addresses) are updated.
Secondary hash chains were introduced by commit 30fff9231fad ("udp:
bind() optimisation") and, as a result, a rehash operation became
needed to make a bound socket reachable again after a connect().
This operation was introduced by commit 719f835853a9 ("udp: add
rehash on connect()") which isn't however a complete fix: the
socket will be found once the rehashing completes, but not while
it's pending.
This is noticeable with a socat(1) server in UDP4-LISTEN mode, and a
client sending datagrams to it. After the server receives the first
datagram (cf. _xioopen_ipdgram_listen()), it issues a connect() to
the address of the sender, in order to set up a directed flow.
Now, if the client, running on a different CPU thread, happens to
send a (subsequent) datagram while the server's socket changes its
address, but is not rehashed yet, this will result in a failed
lookup and a port unreachable error delivered to the client, as
apparent from the following reproducer:
LEN=$(($(cat /proc/sys/net/core/wmem_default) / 4))
dd if=/dev/urandom bs=1 count=${LEN} of=tmp.in
while :; do
taskset -c 1 socat UDP4-LISTEN:1337,null-eof OPEN:tmp.out,create,trunc &
sleep 0.1 || sleep 1
taskset -c 2 socat OPEN:tmp.in UDP4:localhost:1337,shut-null
wait
done
where the client will eventually get ECONNREFUSED on a write()
(typically the second or third one of a given iteration):
2024/11/13 21:28:23 socat[46901] E write(6, 0x556db2e3c000, 8192): Connection refused
This issue was first observed as a seldom failure in Podman's tests
checking UDP functionality while using pasta(1) to connect the
container's network namespace, which leads us to a reproducer with
the lookup error resulting in an ICMP packet on a tap device:
LOCAL_ADDR="$(ip -j -4 addr show|jq -rM '.[] | .addr_info[0] | select(.scope == "global").local')"
while :; do
./pasta --config-net -p pasta.pcap -u 1337 socat UDP4-LISTEN:1337,null-eof OPEN:tmp.out,create,trunc &
sleep 0.2 || sleep 1
socat OPEN:tmp.in UDP4:${LOCAL_ADDR}:1337,shut-null
wait
cmp tmp.in tmp.out
done
Once this fails:
tmp.in tmp.out differ: char 8193, line 29
we can finally have a look at what's going on:
$ tshark -r pasta.pcap

On the third datagram received, the network namespace of the container
initiates an ARP lookup to deliver the ICMP message.
In another variant of this reproducer, starting the client with:
strace -f pasta --config-net -u 1337 socat UDP4-LISTEN:1337,null-eof OPEN:tmp.out,create,trunc 2>strace.log &
and connecting to the socat server using a loopback address:
socat OPEN:tmp.in UDP4:localhost:1337,shut-null
we can more clearly observe a sendmmsg() call failing after the
first datagram is delivered:
[pid 278012] connect(173, 0x7fff96c95fc0, 16) = 0
[...]
[pid 278012] recvmmsg(173, 0x7fff96c96020, 1024, MSG_DONTWAIT, NULL) = -1 EAGAIN (Resource temporarily unavailable)
[pid 278012] sendmmsg(173, 0x561c5ad0a720, 1, MSG_NOSIGNAL) = 1
[...]
[pid 278012] sendmmsg(173, 0x561c5ad0a720, 1, MSG_NOSIGNAL) = -1 ECONNREFUSED (Connection refused)
and, somewhat confusingly, after a connect() on the same socket
succeeded.
Until commit 4cdeeee9252a ("net: udp: prefer listeners bound to an
address"), the race between receive address change and lookup didn't
actually cause visible issues, because, once the lookup based on the
secondary hash chain failed, we would still attempt a lookup based on
the primary hash (destination port only), and find the socket with the
outdated secondary hash.
That change, however, dropped port-only lookups altogether, as side
effect, making the race visible.
To fix this, while avoiding the need to make address changes and
rehash atomic against lookups, reintroduce primary hash lookups as
fallback, if lookups based on four-tuple and secondary hashes fail.
To this end, introduce a simplified lookup implementation, which
doesn't take care of SO_REUSEPORT groups: if we have one, there are
multiple sockets that would match the four-tuple or secondary hash,
meaning that we can't run into this race at all.
v2:
- instead of synchronising lookup operations against address change
plus rehash, reintroduce a simplified version of the original
primary hash lookup as fallback
v1:
- fix build with CONFIG_IPV6=n: add ifdef around sk_v6_rcv_saddr
usage (Kuniyuki Iwashima)
- directly use sk_rcv_saddr for IPv4 receive addresses instead of
fetching inet_rcv_saddr (Kuniyuki Iwashima)
- move inet_update_saddr() to inet_hashtables.h and use that
to set IPv4/IPv6 addresses as suitable (Kuniyuki Iwashima)
- rebase onto net-next, update commit message accordingly

commit b45f721775947a84996deb5c661602254ce25ce6 upstream.
When loading guest XSAVE state via KVM_SET_XSAVE, and when updating XFD in
response to a guest WRMSR, clear XFD-disabled features in the saved (or to
be restored) XSTATE_BV to ensure KVM doesn't attempt to load state for
features that are disabled via the guest's XFD. Because the kernel
executes XRSTOR with the guest's XFD, saving XSTATE_BV[i]=1 with XFD[i]=1
will cause XRSTOR to #NM and panic the kernel.
E.g. if fpu_update_guest_xfd() sets XFD without clearing XSTATE_BV:

The new behavior is consistent with the AMX architecture. Per Intel's SDM,
XSAVE saves XSTATE_BV as '0' for components that are disabled via XFD
(and non-compacted XSAVE saves the initial configuration of the state
component):
If XSAVE, XSAVEC, XSAVEOPT, or XSAVES is saving the state component i,
the instruction does not generate #NM when XCR0[i] = IA32_XFD[i] = 1;
instead, it operates as if XINUSE[i] = 0 (and the state component was
in its initial state): it saves bit i of XSTATE_BV field of the XSAVE
header as 0; in addition, XSAVE saves the initial configuration of the
state component (the other instructions do not save state component i).
Alternatively, KVM could always do XRSTOR with XFD=0, e.g. by using
a constant XFD based on the set of enabled features when XSAVEing for
a struct fpu_guest. However, having XSTATE_BV[i]=1 for XFD-disabled
features can only happen in the above interrupt case, or in similar
scenarios involving preemption on preemptible kernels, because
fpu_swap_kvm_fpstate()'s call to save_fpregs_to_fpstate() saves the
outgoing FPU state with the current XFD; and that is (on all but the
first WRMSR to XFD) the guest XFD.
Therefore, XFD can only go out of sync with XSTATE_BV in the above
interrupt case, or in similar scenarios involving preemption on
preemptible kernels, and it we can consider it (de facto) part of KVM
ABI that KVM_GET_XSAVE returns XSTATE_BV[i]=0 for XFD-disabled features.

The new behavior is consistent with the AMX architecture. Per Intel's SDM,
XSAVE saves XSTATE_BV as '0' for components that are disabled via XFD
(and non-compacted XSAVE saves the initial configuration of the state
component):
If XSAVE, XSAVEC, XSAVEOPT, or XSAVES is saving the state component i,
the instruction does not generate #NM when XCR0[i] = IA32_XFD[i] = 1;
instead, it operates as if XINUSE[i] = 0 (and the state component was
in its initial state): it saves bit i of XSTATE_BV field of the XSAVE
header as 0; in addition, XSAVE saves the initial configuration of the
state component (the other instructions do not save state component i).
Alternatively, KVM could always do XRSTOR with XFD=0, e.g. by using
a constant XFD based on the set of enabled features when XSAVEing for
a struct fpu_guest. However, having XSTATE_BV[i]=1 for XFD-disabled
features can only happen in the above interrupt case, or in similar
scenarios involving preemption on preemptible kernels, because
fpu_swap_kvm_fpstate()'s call to save_fpregs_to_fpstate() saves the
outgoing FPU state with the current XFD; and that is (on all but the
first WRMSR to XFD) the guest XFD.
Therefore, XFD can only go out of sync with XSTATE_BV in the above
interrupt case, or in similar scenarios involving preemption on
preemptible kernels, and it we can consider it (de facto) part of KVM
ABI that KVM_GET_XSAVE returns XSTATE_BV[i]=0 for XFD-disabled features.

Currently, x86, Riscv, Loongarch use the Generic Entry which makes
maintainers' work easier and codes more elegant. arm64 has already
successfully switched to the Generic IRQ Entry in commit
b3cf07851b6c ("arm64: entry: Switch to generic IRQ entry"), it is
time to completely convert arm64 to Generic Entry.
The goal is to bring arm64 in line with other architectures that already
use the generic entry infrastructure, reducing duplicated code and
making it easier to share future changes in entry/exit paths, such as
"Syscall User Dispatch".
This patch set is rebased on arm64 (for-next/entry). And the performance
was measured on Kunpeng 920 using "perf bench basic syscall" with
"arm64.nopauth selinux=0 audit=1".
After switch to Generic Entry, the performance are below:
| Metric | W/O Generic Framework | With Generic Framework | Change |
| ---------- | --------------------- | ---------------------- | ------ |
| Total time | 2.487 [sec] | 2.393[sec] | ↓3.8% |
| usecs/op | 0.248780 | 0.239361 | ↓3.8% |
| ops/sec | 4,019,620 | 4,177,789 | ↑3.9% |
Compared to earlier with arch specific handling, the performance improved
by approximately 3.9%.
On the basis of optimizing syscall_get_arguments()[1], el0_svc_common()
and syscall_exit_work(), the performance are below:
| Metric | W/O Generic Entry | With Generic Entry opt| Change |
| ---------- | ----------------- | ------------------ | ------ |
| Total time | 2.487 [sec] | 2.264 [sec] | ↓9.0% |
| usecs/op | 0.248780 | 0.226481 | ↓9.0% |
| ops/sec | 4,019,620 | 4,415,383 | ↑9.8% |
Therefore, after the optimization, ARM64 System Call performance improved
by approximately 9%.
It was tested ok with following test cases on kunpeng920 and QEMU
virt platform:
- Perf tests.
- Different `dynamic preempt` mode switch.
- Pseudo NMI tests.
- Stress-ng CPU stress test.
- Hackbench stress test.
- MTE test case in Documentation/arch/arm64/memory-tagging-extension.rst
and all test cases in tools/testing/selftests/arm64/mte/*.
- "sud" selftest testcase.
- get_set_sud, get_syscall_info, set_syscall_info, peeksiginfo
in tools/testing/selftests/ptrace.
- breakpoint_test_arm64 in selftests/breakpoints.
- syscall-abi and ptrace in tools/testing/selftests/arm64/abi
- fp-ptrace, sve-ptrace, za-ptrace in selftests/arm64/fp.
- vdso_test_getrandom in tools/testing/selftests/vDSO
- Strace tests.

category: bugfix
bugzilla: https://atomgit.com/openeuler/kernel/issues/8435
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
When creating a synthetic event based on an existing synthetic event that
had a stacktrace field and the new synthetic event used that field a
kernel crash occurred:
~# cd /sys/kernel/tracing
~# echo 's:stack unsigned long stack[];' > dynamic_events
~# echo 'hist:keys=prev_pid:s0=common_stacktrace if prev_state & 3' >> events/sched/sched_switch/trigger
~# echo 'hist:keys=next_pid:s1=$s0:onmatch(sched.sched_switch).trace(stack,$s1)' >> events/sched/sched_switch/trigger
The above creates a synthetic event that takes a stacktrace when a task
schedules out in a non-running state and passes that stacktrace to the
sched_switch event when that task schedules back in. It triggers the
"stack" synthetic event that has a stacktrace as its field (called "stack").
~# echo 's:syscall_stack s64 id; unsigned long stack[];' >> dynamic_events
~# echo 'hist:keys=common_pid:s2=stack' >> events/synthetic/stack/trigger
~# echo 'hist:keys=common_pid:s3=$s2,i0=id:onmatch(synthetic.stack).trace(syscall_stack,$i0,$s3)' >> events/raw_syscalls/sys_exit/trigger
The above makes another synthetic event called "syscall_stack" that
attaches the first synthetic event (stack) to the sys_exit trace event and
records the stacktrace from the stack event with the id of the system call
that is exiting.
When enabling this event (or using it in a historgram):
~# echo 1 > events/synthetic/syscall_stack/enable
Produces a kernel crash!

The reason is that the stacktrace field is not labeled as such, and is
treated as a normal field and not as a dynamic event that it is.
In trace_event_raw_event_synth() the event is field is still treated as a
dynamic array, but the retrieval of the data is considered a normal field,
and the reference is just the meta data:
// Meta data is retrieved instead of a dynamic array
str_val = (char *)(long)var_ref_vals[val_idx];
// Then when it tries to process it:
len = *((unsigned long *)str_val) + 1;
It triggers a kernel page fault.
To fix this, first when defining the fields of the first synthetic event,
set the filter type to FILTER_STACKTRACE. This is used later by the second
synthetic event to know that this field is a stacktrace. When creating
the field of the new synthetic event, have it use this FILTER_STACKTRACE
to know to create a stacktrace field to copy the stacktrace into.

[PATCH OLK-6.6] ima: don't clear IMA_DIGSIG flag when setting or removing non-IMA xattr

commit d2993a7e98eb70c737c6f5365a190e79c72b8407
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/11626
CVE: CVE-2025-68183
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 88b4cbcf6b041ae0f2fc8a34554a5b6a83a2b7cd ]
Currently when both IMA and EVM are in fix mode, the IMA signature will
be reset to IMA hash if a program first stores IMA signature in
security.ima and then writes/removes some other security xattr for the
file.
For example, on Fedora, after booting the kernel with "ima_appraise=fix
evm=fix ima_policy=appraise_tcb" and installing rpm-plugin-ima,
installing/reinstalling a package will not make good reference IMA
signature generated. Instead IMA hash is generated,
# getfattr -m - -d -e hex /usr/bin/bash
# file: usr/bin/bash
security.ima=0x0404...
This happens because when setting security.selinux, the IMA_DIGSIG flag
that had been set early was cleared. As a result, IMA hash is generated
when the file is closed.
Similarly, IMA signature can be cleared on file close after removing
security xattr like security.evm or setting/removing ACL.
Prevent replacing the IMA file signature with a file hash, by preventing
the IMA_DIGSIG flag from being reset.
Here's a minimal C reproducer which sets security.selinux as the last
step which can also replaced by removing security.evm or setting ACL,
#include <stdio.h>
#include <sys/xattr.h>
#include <fcntl.h>
#include <unistd.h>
#include <string.h>
#include <stdlib.h>
int main() {
const char* file_path = "/usr/sbin/test_binary";
const char* hex_string = "030204d33204490066306402304";
int length = strlen(hex_string);
char* ima_attr_value;
int fd;
fd = open(file_path, O_WRONLY|O_CREAT|O_EXCL, 0644);
if (fd == -1) {
perror("Error opening file");
return 1;
}
ima_attr_value = (char*)malloc(length / 2 );
for (int i = 0, j = 0; i < length; i += 2, j++) {
sscanf(hex_string + i, "%2hhx", &ima_attr_value[j]);
}
if (fsetxattr(fd, "security.ima", ima_attr_value, length/2, 0) == -1) {
perror("Error setting extended attribute");
close(fd);
return 1;
}
const char* selinux_value= "system_u:object_r:bin_t:s0";
if (fsetxattr(fd, "security.selinux", selinux_value, strlen(selinux_value), 0) == -1) {

--------------------------------
commit 737bb912ebbe4571195c56eba557c4d7315b26fb upstream.
This patch is a mitigation to prevent the A-MSDU spoofing vulnerability
for mesh networks. The initial update to the IEEE 802.11 standard, in
response to the FragAttacks, missed this case (CVE-2025-27558). It can
be considered a variant of CVE-2020-24588 but for mesh networks.
This patch tries to detect if a standard MSDU was turned into an A-MSDU
by an adversary. This is done by parsing a received A-MSDU as a standard
MSDU, calculating the length of the Mesh Control header, and seeing if
the 6 bytes after this header equal the start of an rfc1042 header. If
equal, this is a strong indication of an ongoing attack attempt.
This defense was tested with mac80211_hwsim against a mesh network that
uses an empty Mesh Address Extension field, i.e., when four addresses
are used, and when using a 12-byte Mesh Address Extension field, i.e.,
when six addresses are used. Functionality of normal MSDUs and A-MSDUs
was also tested, and confirmed working, when using both an empty and
12-byte Mesh Address Extension field.
It was also tested with mac80211_hwsim that A-MSDU attacks in non-mesh
networks keep being detected and prevented.
Note that the vulnerability being patched, and the defense being
implemented, was also discussed in the following paper and in the
following IEEE 802.11 presentation:

category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13354
CVE: CVE-2025-68801
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 8b0e69763ef948fb872a7767df4be665d18f5fd4 ]
We sometimes observe use-after-free when dereferencing a neighbour [1].
The problem seems to be that the driver stores a pointer to the
neighbour, but without holding a reference on it. A reference is only
taken when the neighbour is used by a nexthop.
Fix by simplifying the reference counting scheme. Always take a
reference when storing a neighbour pointer in a neighbour entry. Avoid
taking a referencing when the neighbour is used by a nexthop as the
neighbour entry associated with the nexthop already holds a reference.
Tested by running the test that uncovered the problem over 300 times.
Without this patch the problem was reproduced after a handful of
iterations.

--------------------------------
[ Upstream commit 8ac1dacec458f55f871f7153242ed6ab60373b90 ]
Cited commit added a dedicated mutex (instead of RTNL) to protect the
multicast route list, so that it will not change while the driver
periodically traverses it in order to update the kernel about multicast
route stats that were queried from the device.
One instance of list entry deletion (during route replace) was missed
and it can result in a use-after-free [1].
Fix by acquiring the mutex before deleting the entry from the list and
releasing it afterwards.

avoid warning, add !folio_test_hugetlb(old). The mem_cgroup_replace_folio
is only used by fuse or shmem, the !folio_test_hugetlb(old) is unnecessary,

No kernel log of the exact same error with an upstream kernel is
available - but the very same deadlock situation can be constructed there,
too:
- task: kmcheck
mlx5_unload_one() tries to acquire devlink lock while the PCI error
recovery code has set pdev->block_cfg_access by way of
pci_cfg_access_lock()
- task: kworker
mlx5_crdump_collect() tries to set block_cfg_access through
pci_cfg_access_lock() while devlink_health_report() had acquired
the devlink lock.
A similar deadlock situation can be reproduced by requesting a
crdump with
> devlink health dump show pci/<BDF> reporter fw_fatal
while PCI error recovery is executed on the same <BDF> physical function
by mlx5_core's pci_error_handlers. On s390 this can be injected with
> zpcictl --reset-fw <BDF>
Tests with this patch failed to reproduce that second deadlock situation,
the devlink command is rejected with "kernel answers: Permission denied" -
and we get a kernel log message of:
mlx5_core 1ed0:00:00.1: mlx5_crdump_collect:50:(pid 254382): crdump: failed to lock vsc gw err -5
because the config read of VSC_SEMAPHORE is rejected by the underlying
hardware.
Two prior attempts to address this issue have been discussed and
ultimately rejected [see link], with the primary argument that s390's
implementation of PCI error recovery is imposing restrictions that
neither powerpc's EEH nor PCI AER handling need. Tests show that PCI
error recovery on s390 is running to completion even without blocking
access to PCI config space.

--------------------------------
[ Upstream commit 0fd20f65df6aa430454a0deed8f43efa91c54835 ]
Do not block PCI config accesses through pci_cfg_access_lock() when
executing the s390 variant of PCI error recovery: Acquire just
device_lock() instead of pci_dev_lock() as powerpc's EEH and
generig PCI AER processing do.
During error recovery testing a pair of tasks was reported to be hung:

[PATCH OLK-6.6] KVM: SVM: Reject SEV{-ES} intra host migration if vCPU creation is in-flight

CVE: CVE-2025-38455
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit ecf371f8b02d5e31b9aa1da7f159f1b2107bdb01 upstream.
Reject migration of SEV{-ES} state if either the source or destination VM
is actively creating a vCPU, i.e. if kvm_vm_ioctl_create_vcpu() is in the
section between incrementing created_vcpus and online_vcpus. The bulk of
vCPU creation runs _outside_ of kvm->lock to allow creating multiple vCPUs
in parallel, and so sev_info.es_active can get toggled from false=>true in
the destination VM after (or during) svm_vcpu_create(), resulting in an
SEV{-ES} VM effectively having a non-SEV{-ES} vCPU.
The issue manifests most visibly as a crash when trying to free a vCPU's
NULL VMSA page in an SEV-ES VM, but any number of things can go wrong.

Deliberately don't check for a NULL VMSA when freeing the vCPU, as crashing
the host is likely desirable due to the VMSA being consumed by hardware.
E.g. if KVM manages to allow VMRUN on the vCPU, hardware may read/write a
bogus VMSA page. Accessing PFN 0 is "fine"-ish now that it's sequestered
away thanks to L1TF, but panicking in this scenario is preferable to
potentially running with corrupted state.

CVE: CVE-2025-39828
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit ec79003c5f9d2c7f9576fc69b8dbda80305cbe3a ]
syzbot reported the splat below. [0]
When atmtcp_v_open() or atmtcp_v_close() is called via connect()
or close(), atmtcp_send_control() is called to send an in-kernel
special message.
The message has ATMTCP_HDR_MAGIC in atmtcp_control.hdr.length.
Also, a pointer of struct atm_vcc is set to atmtcp_control.vcc.
The notable thing is struct atmtcp_control is uAPI but has a
space for an in-kernel pointer.
struct atmtcp_control {
struct atmtcp_hdr hdr; /* must be first */
...
atm_kptr_t vcc; /* both directions */
...
} __ATM_API_ALIGN;
typedef struct { unsigned char _[8]; } __ATM_API_ALIGN atm_kptr_t;
The special message is processed in atmtcp_recv_control() called
from atmtcp_c_send().
atmtcp_c_send() is vcc->dev->ops->send() and called from 2 paths:
1. .ndo_start_xmit() (vcc->send() == atm_send_aal0())
2. vcc_sendmsg()
The problem is sendmsg() does not validate the message length and
userspace can abuse atmtcp_recv_control() to overwrite any kptr
by atmtcp_control.
Let's add a new ->pre_send() hook to validate messages from sendmsg().

--------------------------------
[ Upstream commit 9882a40640036d5bbc590426a78981526d4f2345 ]
Commit c410fa9b07c3 ("drm/mediatek: Add AFBC support to Mediatek DRM
driver") added AFBC support to Mediatek DRM and enabled the
32x8/split/sparse modifier.
However, this is currently broken on Mediatek MT8188 (Genio 700 EVK
platform); tested using upstream Kernel and Mesa (v25.2.1), AFBC is used by
default since Mesa v25.0.
Kernel trace reports vblank timeouts constantly, and the render is garbled:

--------------------------------
The namespaces can access the controller's admin request_queue, and
stale references on the namespaces may exist after tearing down the
controller. Ensure the admin request_queue is active by moving the
controller's 'put' to after all controller references have been released
to ensure no one is can access the request_queue. This fixes a reported
use-after-free bug:

[PATCH OLK-6.6 0/9] arm_mpam: Introduce the Narrow-PARTID feature for MPAM driver
by Zeng Heng 26 Jan '26
by Zeng Heng 26 Jan '26
26 Jan '26
The narrow-partid feature in MPAM allows for a more efficient use of
PARTIDs by enabling a many-to-one mapping of reqpartids (requested PARTIDs)
to intpartids (internal PARTIDs). This mapping reduces the number of unique
PARTIDs needed, thus allowing more tasks or processes to be monitored and
managed with the available resources.
For a mixture of MSCs system, for MSCs that do not support narrow-partid,
we use the PARTIDs exceeding the number of closids as reqPARTIDs for
expanding the monitoring groups.
Therefore, we will expand the information contained in the RMID, so that it
includes not only PMG, but also reqPARTIDs information. The new RMID would
be like:
RMID = (reqPARTID << shift | PMG).
Each control group has m (req)PARTIDs, which are used to expand the
number of monitoring groups under one control group. Therefore, the number
of monitoring groups is no longer limited by the range of MPAM's PMG, which
enhances the extensibility of the system's monitoring capabilities.

arm_mpam: Set INTERNAL as needed when setting MSC controls
Zeng Heng (8):
arm_mpam: Introduce the definitions of intPARTID and reqPARTID
arm_mpam: Add limitation for the Narrow-PARTID feature
arm_mpam: Expand the composition of RMID

There is a stale data issue caused by merging 9e891675aab8. After
the patch was merged, data writeback before punch hole cancellation
was canceled. This led to some regions of unwritten extents not

--------------------------------
Commit bde5f6bc68db ("kmemleak: add scheduling point to kmemleak_scan()")
added a cond_resched() call to the struct page scanning loop to prevent
soft lockup from happening. However, soft lockup can still happen in that
loop in some corner cases when the pages that satisfy the "!(pfn & 63)"
check are skipped for some reasons.
Fix this corner case by moving up the cond_resched() check so that it will
be called every 64 pages unconditionally.

In smb3_reconfigure(), if smb3_sync_session_ctx_passwords() fails, the

Fix this by calling kfree_sensitive() on both password buffers before
returning in this error case.

software_node_get_reference_args() wants to get @index-th element, so
the property value requires at least '(index + 1) * sizeof(*ref)' bytes
but that can not be guaranteed by current OOB check, and may cause OOB
for malformed property.

[PATCH OLK-6.6] cifs: Fix memory and information leak in smb3_reconfigure()

category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13475
CVE: CVE-2025-71151
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
In smb3_reconfigure(), if smb3_sync_session_ctx_passwords() fails, the
function returns immediately without freeing and erasing the newly
allocated new_password and new_password2. This causes both a memory leak
and a potential information leak.
Fix this by calling kfree_sensitive() on both password buffers before
returning in this error case.

Commit 35c18f2933c5 ("Add a new optional ",cma" suffix to the
crashkernel= command line option") and commit ab475510e042 ("kdump:
implement reserve_crashkernel_cma") added CMA support for kdump
crashkernel reservation. This allows the kernel to dynamically allocate
contiguous memory for crash dumping when needed, rather than permanently
reserving a fixed region at boot time.
So extend crashkernel CMA reservation support to riscv. The following
changes are made to enable CMA reservation:
- Parse and obtain the CMA reservation size along with other crashkernel
parameters.
- Call reserve_crashkernel_cma() to allocate the CMA region for kdump.
- Include the CMA-reserved ranges for kdump kernel to use.
- Exclude the CMA-reserved ranges from the crash kernel memory to
prevent them from being exported through /proc/vmcore.
Update kernel-parameters.txt to document CMA support for crashkernel on
riscv architecture.

ret_from_fork+0x2d/0x50
The stress test involves CPU hotplug operations and memory control group
(memcg) operations. The scenario can be described as follows:
echo xx > memory.max cache_ap_online oom_reaper
(CPU23) (CPU50)
xx < usage stop_machine_from_inactive_cpu
for(;;) // all active cpus
trigger OOM queue_stop_cpus_work
// waiting oom_reaper
multi_cpu_stop(migration/xx)
// sync all active cpus ack
// waiting cpu23 ack
// CPU50 loops in multi_cpu_stop
waiting cpu50
Detailed explanation:
1. When the usage is larger than xx, an OOM may be triggered. If the
process does not handle with ths kill signal immediately, it will loop
in the memory_max_write.
2. When cache_ap_online is triggered, the multi_cpu_stop is queued to the
active cpus. Within the multi_cpu_stop function, it attempts to
synchronize the CPU states. However, the CPU23 didn't acknowledge
because it is stuck in a loop within the for(;;).
3. The oom_reaper process is blocked because CPU50 is in a loop, waiting
for CPU23 to acknowledge the synchronization request.
4. Finally, it formed cyclic dependency and lead to softlockup and dead
loop.
To fix this issue, add cond_resched() in the memory_max_write, so that it
will not block migration task.

[PATCH OLK-5.10] HID: core: Harden s32ton() against conversion to 0 bits

category: bugfix

CVE: CVE-2025-38556
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
Testing by the syzbot fuzzer showed that the HID core gets a
shift-out-of-bounds exception when it tries to convert a 32-bit
quantity to a 0-bit quantity. Ideally this should never occur, but
there are buggy devices and some might have a report field with size
set to zero; we shouldn't reject the report or the device just because
of that.
Instead, harden the s32ton() routine so that it returns a reasonable
result instead of crashing when it is called with the number of bits
set to 0 -- the same as what snto32() does.

category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13342
CVE: CVE-2025-68789
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
The ibmpex_high_low_store() function retrieves driver data using
dev_get_drvdata() and uses it without validation. This creates a race
condition where the sysfs callback can be invoked after the data
structure is freed, leading to use-after-free.
Fix by adding a NULL check after dev_get_drvdata(), and reordering
operations in the deletion path to prevent TOCTOU.

category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICGAML
CVE: CVE-2022-50159
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
Presently ima_get_kexec_buffer() doesn't check if the previous kernel's
ima-kexec-buffer lies outside the addressable memory range. This can result
in a kernel panic if the new kernel is booted with 'mem=X' arg and the
ima-kexec-buffer was allocated beyond that range by the previous kernel.
The panic is usually of the form below:
$ sudo kexec --initrd initrd vmlinux --append='mem=16G'

Fix this issue by checking returned PFN range of previous kernel's
ima-kexec-buffer with page_is_ram() to ensure correct memory bounds.

--------------------------------
Since commit ebff7d8f270d ("mem hotunplug: fix kfree() of bootmem
memory"), we could get a resource allocated during boot via
alloc_resource(). And it's required to release the resource using
free_resource(). Howerver, many people use kfree directly which will
result in kernel BUG. In order to fix this without fixing every call
site, just leak a couple of bytes in such corner case.

--------------------------------
In e1000_tbi_should_accept() we read the last byte of the frame via
'data[length - 1]' to evaluate the TBI workaround. If the descriptor-
reported length is zero or larger than the actual RX buffer size, this
read goes out of bounds and can hit unrelated slab objects. The issue
is observed from the NAPI receive path (e1000_clean_rx_irq):

page dumped because: kasan: bad access detected
==================================================================
This happens because the TBI check unconditionally dereferences the last
byte without validating the reported length first:
u8 last_byte = *(data + length - 1);
Fix by rejecting the frame early if the length is zero, or if it exceeds
adapter->rx_buffer_len. This preserves the TBI workaround semantics for
valid frames and prevents touching memory beyond the RX buffer.
Fixes: 2037110c96d5 ("e1000: move tbi workaround code into helper function")

[ Upstream commit 6daa2893f323981c7894c68440823326e93a7d61 ]
There are off-by-one bugs when configuring RSS hash key and lookup
table, causing out-of-bounds reads to memory [1] and out-of-bounds
writes to device registers.
Before commit 43a3d9ba34c9 ("i40evf: Allow PF driver to configure RSS"),
the loop upper bounds were:
i <= I40E_VFQF_{HKEY,HLUT}_MAX_INDEX
which is safe since the value is the last valid index.
That commit changed the bounds to:
i <= adapter->rss_{key,lut}_size / 4
where `rss_{key,lut}_size / 4` is the number of dwords, so the last
valid index is `(rss_{key,lut}_size / 4) - 1`. Therefore, using `<=`
accesses one element past the end.
Fix the issues by using `<` instead of `<=`, ensuring we do not exceed
the bounds.

In e1000_tbi_should_accept() we read the last byte of the frame via
'data[length - 1]' to evaluate the TBI workaround. If the descriptor-
reported length is zero or larger than the actual RX buffer size, this
read goes out of bounds and can hit unrelated slab objects. The issue
is observed from the NAPI receive path (e1000_clean_rx_irq):

page dumped because: kasan: bad access detected
==================================================================
This happens because the TBI check unconditionally dereferences the last
byte without validating the reported length first:
u8 last_byte = *(data + length - 1);
Fix by rejecting the frame early if the length is zero, or if it exceeds
adapter->rx_buffer_len. This preserves the TBI workaround semantics for
valid frames and prevents touching memory beyond the RX buffer.

--------------------------------
[ Upstream commit 569922b82ca660f8b24e705f6cf674e6b1f99cc7 ]
Each cpu DAI should associate with a widget. However, the topology might
not create the right number of DAI widgets for aggregated amps. And it
will cause NULL pointer deference.
Check that the DAI widget associated with the CPU DAI is valid to prevent
NULL pointer deference due to missing DAI widgets in topologies with
aggregated amps.

Commit 35c18f2933c5 ("Add a new optional ",cma" suffix to the
crashkernel= command line option") and commit ab475510e042 ("kdump:
implement reserve_crashkernel_cma") added CMA support for kdump
crashkernel reservation.
Crash kernel memory reservation wastes production resources if too
large, risks kdump failure if too small, and faces allocation difficulties
on fragmented systems due to contiguous block constraints. The new CMA-based
crashkernel reservation scheme splits the "large fixed reservation" into
a "small fixed region + large CMA dynamic region": the CMA memory is
available to userspace during normal operation to avoid waste, and is
reclaimed for kdump upon crash—saving memory while improving reliability.
So extend crashkernel CMA reservation support to arm64. The following changes
are made to enable CMA reservation:
- Parse and obtain the CMA reservation size along with other crashkernel
parameters.
- Call reserve_crashkernel_cma() to allocate the CMA region for kdump.
- Include the CMA-reserved ranges for kdump kernel to use.
- Exclude the CMA-reserved ranges from the crash kernel memory to
prevent them from being exported through /proc/vmcore.
Update kernel-parameters.txt to document CMA support for crashkernel on
arm64 architecture.

[PATCH OLK-5.10] ntfs: set dummy blocksize to read boot_block when mounting
by Li Lingfeng 23 Jan '26

commit d1693a7d5a38acf6424235a6070bcf5b186a360d
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13378
CVE: CVE-2025-71067
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
When mounting, sb->s_blocksize is used to read the boot_block without
being defined or validated. Set a dummy blocksize before attempting to
read the boot_block.
The issue can be triggered with the following syz reproducer:
mkdirat(0xffffffffffffff9c, &(0x7f0000000080)='./file1\x00', 0x0)
r4 = openat$nullb(0xffffffffffffff9c, &(0x7f0000000040), 0x121403, 0x0)
ioctl$FS_IOC_SETFLAGS(r4, 0x40081271, &(0x7f0000000980)=0x4000)
mount(&(0x7f0000000140)=@nullb, &(0x7f0000000040)='./cgroup\x00',
&(0x7f0000000000)='ntfs3\x00', 0x2208004, 0x0)
syz_clone(0x88200200, 0x0, 0x0, 0x0, 0x0, 0x0)
Here, the ioctl sets the bdev block size to 16384. During mount,
get_tree_bdev_flags() calls sb_set_blocksize(sb, block_size(bdev)),
but since block_size(bdev) > PAGE_SIZE, sb_set_blocksize() leaves
sb->s_blocksize at zero.
Later, ntfs_init_from_boot() attempts to read the boot_block while
sb->s_blocksize is still zero, which triggers the bug.

Fix aRFS (accelerated Receive Flow Steering) structures memory leak by
adding a checker to verify if aRFS memory is already allocated while
configuring VSI. aRFS objects are allocated in two cases:
- as part of VSI initialization (at probe), and
- as part of reset handling
However, VSI reconfiguration executed during reset involves memory
allocation one more time, without prior releasing already allocated
resources. This led to the memory leak with the following signature:

Extend crashkernel CMA reservation support to arm64.
The following changes are made to enable CMA reservation on powerpc:
- Parse and obtain the CMA reservation size along with other crashkernel
parameters.
- Call reserve_crashkernel_cma() to allocate the CMA region for kdump.
- Include the CMA-reserved ranges for kdump kernel to use.
- Exclude the CMA-reserved ranges from the crash kernel memory to
prevent them from being exported through /proc/vmcore.
Update kernel-parameters.txt to document CMA support for crashkernel on
arm64 architecture.

commit 039bef30e320827bac8990c9f29d2a68cd8adb5f
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13326
CVE: CVE-2025-68771
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
syzbot reported a kernel BUG in ocfs2_find_victim_chain() because the
`cl_next_free_rec` field of the allocation chain list (next free slot in
the chain list) is 0, triggring the BUG_ON(!cl->cl_next_free_rec)
condition in ocfs2_find_victim_chain() and panicking the kernel.
To fix this, an if condition is introduced in ocfs2_claim_suballoc_bits(),
just before calling ocfs2_find_victim_chain(), the code block in it being
executed when either of the following conditions is true:
1. `cl_next_free_rec` is equal to 0, indicating that there are no free
chains in the allocation chain list
2. `cl_next_free_rec` is greater than `cl_count` (the total number of
chains in the allocation chain list)
Either of them being true is indicative of the fact that there are no
chains left for usage.
This is addressed using ocfs2_error(), which prints
the error log for debugging purposes, rather than panicking the kernel.

[PATCH v4 openEuler-25.03 0/1] NUMA ro-data replication for userspace applications
by Nikita Panov 22 Jan '26
by Nikita Panov 22 Jan '26
22 Jan '26
This patchset implements support of userspace translation tables and
private read-only data replication for AArch64 and is going to
improve latency and memory bandwidth by reducing cross-NUMA memory accesses.
openEuler 25.03 is used as a baseline.
Current implementation supports next functionality:
1. Per-NUMA node replication of userspace translation tables and private read-only data.
We replicate only __private read-only__ data to avoid dealing with
replicas coherence and consistency support. Translation tables, in turn, are able to be
replicated for any kind of underlying data.
2. Ability to enable userspace replication for a certain process via procfs or
for a group of processes via memory cgroup.
3. 4K and 64K pages are supported.
4. Replicated data pages can't be a ksm, migration or swap/reclaim candidates by design.
But for other pages these work as well with replicated translation tables support.
Once the user replication was enabled for a process via either procfs or memory cgroup,
all it's existing private read-only data will be immediately replicated
with translation tables for them. Later, as the process running, __any__ page fault occured
will cause replicating of translation tables related to the faulted address.
Also there is a mechanism implemented on the top of numa-balancer that
will replicate private read-only pages on NUMA faults, as the process running
(numa balancer should be enabled for the mechanism to work).
Known problems:
1. Current implementation doesn't support huge pages,
so you have to build the kernel with huge pages disabled for user replication to work.
Huge pages support will be added in the nearest future.
2. mremap syscall doesn't work with replicated memory yet.
3. page_idle, uprobes and userfaultfd support replicated translation tables,
but not replicated data. Be responsible using these features with userspace replication enabled.
4. When replicating translation tables during page faults,
there should be enough space on __each__ NUMA node for table allocations.
Otherwise it will cause OOM-killer.
Despite the problems above, they are mostly not related to workloads assumed
to benefit from user replication feature,
and such workloads will work properly with the feature enabled.

LeapIO inclusion
category: feature
bugzilla: https://atomgit.com/openeuler/kernel/issues/8338
------------------------------------------
The LeapRAID driver provides support for LeapRAID PCIe RAID controllers,
enabling communication between the host operating system, firmware, and
hardware for efficient storage management.
The main source files are organized as follows:
leapraid_os.c:
Implements the scsi_host_template functions, PCIe device probing, and
initialization routines, integrating the driver with the Linux SCSI
subsystem.
leapraid_func.c:
Provides the core functional routines that handle low-level interactions
with the controller firmware and hardware, including interrupt handling,
topology management, and reset sequence processing, and other related
operations.
leapraid_app.c:
Implements the ioctl interface, providing user-space tools access to device
management and diagnostic operations.
leapraid_transport.c:
Interacts with the Linux SCSI transport layer to add SAS phys and ports.
leapraid_func.h:
Declares common data structures, constants, and function prototypes shared
across the driver.
leapraid.h:
Provides global constants, register mappings, and interface definitions
that facilitate communication between the driver and the controller
firmware.
The leapraid_probe function is called when the driver detects a supported
LeapRAID PCIe device. It allocates and initializes the Scsi_Host structure,
configures hardware and firmware interfaces, and registers the host adapter
with the Linux SCSI mid-layer.
After registration, the driver invokes scsi_scan_host() to initiate device
discovery. The firmware then reports discovered logical and physical
devices to the host through interrupt-driven events and synchronizes their
operational states.
leapraid_adapter is the core data structure that encapsulates all resources
and runtime state information maintained during driver operation, described
as follows:
/**
* struct leapraid_adapter - Main LeapRaid adapter structure
* @list: List head for adapter management
* @shost: SCSI host structure
* @pdev: PCI device structure
* @iomem_base: I/O memory mapped base address
* @rep_msg_host_idx: Host index for reply messages
* @mask_int: Interrupt masking flag
* @timestamp_sync_cnt: Timestamp synchronization counter
* @adapter_attr: Adapter attributes
* @mem_desc: Memory descriptor
* @driver_cmds: Driver commands
* @dynamic_task_desc: Dynamic task descriptor
* @fw_evt_s: Firmware event structure
* @notification_desc: Notification descriptor
* @reset_desc: Reset descriptor
* @scan_dev_desc: Device scan descriptor
* @access_ctrl: Access control
* @fw_log_desc: Firmware log descriptor
* @dev_topo: Device topology
* @boot_devs: Boot devices
* @smart_poll_desc: SMART polling descriptor

LeapIO inclusion
category: feature
bugzilla: https://atomgit.com/openeuler/kernel/issues/8340
------------------------------------------
The LeapRAID driver provides support for LeapRAID PCIe RAID controllers,
enabling communication between the host operating system, firmware, and
hardware for efficient storage management.
The main source files are organized as follows:
leapraid_os.c:
Implements the scsi_host_template functions, PCIe device probing, and
initialization routines, integrating the driver with the Linux SCSI
subsystem.
leapraid_func.c:
Provides the core functional routines that handle low-level interactions
with the controller firmware and hardware, including interrupt handling,
topology management, and reset sequence processing, and other related
operations.
leapraid_app.c:
Implements the ioctl interface, providing user-space tools access to device
management and diagnostic operations.
leapraid_transport.c:
Interacts with the Linux SCSI transport layer to add SAS phys and ports.
leapraid_func.h:
Declares common data structures, constants, and function prototypes shared
across the driver.
leapraid.h:
Provides global constants, register mappings, and interface definitions
that facilitate communication between the driver and the controller
firmware.
The leapraid_probe function is called when the driver detects a supported
LeapRAID PCIe device. It allocates and initializes the Scsi_Host structure,
configures hardware and firmware interfaces, and registers the host adapter
with the Linux SCSI mid-layer.
After registration, the driver invokes scsi_scan_host() to initiate device
discovery. The firmware then reports discovered logical and physical
devices to the host through interrupt-driven events and synchronizes their
operational states.
leapraid_adapter is the core data structure that encapsulates all resources
and runtime state information maintained during driver operation, described
as follows:
/**
* struct leapraid_adapter - Main LeapRaid adapter structure
* @list: List head for adapter management
* @shost: SCSI host structure
* @pdev: PCI device structure
* @iomem_base: I/O memory mapped base address
* @rep_msg_host_idx: Host index for reply messages
* @mask_int: Interrupt masking flag
* @timestamp_sync_cnt: Timestamp synchronization counter
* @adapter_attr: Adapter attributes
* @mem_desc: Memory descriptor
* @driver_cmds: Driver commands
* @dynamic_task_desc: Dynamic task descriptor
* @fw_evt_s: Firmware event structure
* @notification_desc: Notification descriptor
* @reset_desc: Reset descriptor
* @scan_dev_desc: Device scan descriptor
* @access_ctrl: Access control
* @fw_log_desc: Firmware log descriptor
* @dev_topo: Device topology
* @boot_devs: Boot devices
* @smart_poll_desc: SMART polling descriptor

[PATCH OLK-6.6] crypto: af_alg - zero initialize memory allocated via sock_kmalloc
by Yi Yang 22 Jan '26
by Yi Yang 22 Jan '26
22 Jan '26
From: Shivani Agarwal <shivani.agarwal(a)broadcom.com>
stable inclusion
from stable-v6.6.120
commit 84238876e3b3b262cf62d5f4d1338e983fb27010
category: bugfix
bugzilla: https://atomgit.com/src-openeuler/kernel/issues/13428
CVE: CVE-2025-71113
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 6f6e309328d53a10c0fe1f77dec2db73373179b6 upstream.
Several crypto user API contexts and requests allocated with
sock_kmalloc() were left uninitialized, relying on callers to
set fields explicitly. This resulted in the use of uninitialized
data in certain error paths or when new fields are added in the
future.
The ACVP patches also contain two user-space interface files:
algif_kpp.c and algif_akcipher.c. These too rely on proper
initialization of their context structures.
A particular issue has been observed with the newly added
'inflight' variable introduced in af_alg_ctx by commit:
67b164a871af ("crypto: af_alg - Disallow multiple in-flight AIO requests")
Because the context is not memset to zero after allocation,
the inflight variable has contained garbage values. As a result,
af_alg_alloc_areq() has incorrectly returned -EBUSY randomly when
the garbage value was interpreted as true:
https://github.com/gregkh/linux/blame/master/crypto/af_alg.c#L1209
The check directly tests ctx->inflight without explicitly
comparing against true/false. Since inflight is only ever set to
true or false later, an uninitialized value has triggered
-EBUSY failures. Zero-initializing memory allocated with
sock_kmalloc() ensures inflight and other fields start in a known
state, removing random issues caused by uninitialized data.
Fixes: fe869cdb89c9 ("crypto: algif_hash - User-space interface for hash operations")
Fixes: 5afdfd22e6ba ("crypto: algif_rng - add random number generator support")
Fixes: 2d97591ef43d ("crypto: af_alg - consolidation of duplicate code")

--------------------------------
[ Upstream commit 569922b82ca660f8b24e705f6cf674e6b1f99cc7 ]
Each cpu DAI should associate with a widget. However, the topology might
not create the right number of DAI widgets for aggregated amps. And it
will cause NULL pointer deference.
Check that the DAI widget associated with the CPU DAI is valid to prevent
NULL pointer deference due to missing DAI widgets in topologies with
aggregated amps.

---------------------------------------------------------------------------
The do_sea() function defaults to using firmware-first mode, if supported.
It invoke acpi/apei/ghes ghes_notify_sea() to report and handling the SEA
error, The GHES uses a buffer to cache the most recent 4 kinds of SEA
errors. If the same kind SEA error occurs again, GHES will skip to
reporting this SEA error and will not add it to the "ghes_estatus_llist"
list until the cache times out after 10 seconds, at which point the SEA
error will be reprocessed.
The GHES invoke ghes_proc_in_irq() to handle the SEA error, which
ultimately executes memory_failure to process the page with hardware
memory corruption. If the same SEA error appears multiple times
consecutively, it indicates that the previous handling was incomplete or
unable to resolve the fault. In such cases, it is more appropriate to
return a failure when encountering the same error again, and then proceed
to arm64_do_kernel_sea for further processing.
When hardware memory corruption occurs, a memory error interrupt is
triggered. If the kernel accesses this erroneous data, it will trigget
the SEA error exception handler. All such handlers will call
memory_failure() to handle the faulty page.
If a memory error interrupt occurs first, followed by an SEA error
interrupt, the faulty page is first marked as poisoned by the memory error
interrupt process, and then the SEA error interrupt handling process will
send a SIGBUS signel to the process accessing the poisoned page.
However, if the SEA interrupt is reported first, the following exceptional
scenario occurs:
When a user process directly requests and accesses a page with hardware
memory corruption via mmap (such as with devmem), the page containing this
address may still be in a free buddy state in the kernel. At this point,
the page is marked as "poisoned" during the SEA claim memory_failure().
However, since the process does not request the page through the kernel's
MMU, the kernel cannot send SIGBUS signel to the processes. And the memory
error interrupt handling process not support send SIGBUS signel. As a
result, these processes continues to access the faulty page, causing
repeated entries into the SEA exception handler. At this time, it lead to
an SEA error interrupt storm.
The following error logs is explained using the devmem process:
