cleanup:
1) Add a macro to simplify obtaining the packet size
2) Remove redundant checks for cmd and size, as they are always true
3) Use memcpy instead of for loop statements
4) Remove the redundant initialization of ras_rsp_data to 0
5) Other minor cleanup
refactor:
During the dump file process, do not repeatedly open and close the file
No need to subtract the packet header length, then simplify the code for
obtaining the file buffer size.
Add helper of ras_get_rasdfx_header
Add a check to verify if cmd_ret->rsp_data_num is 0
Add a check to verify whether f_header.pkt_num exceeds the maximum value
The header.pkt_length indicates the size in bytes, which needs to be
converted to DWORD size, and then compared with DFX_REG_PACKET_HEAD_LEN
to address potential division by zero issues.
Refactoring of parseing payload.

[PATCH OLK-6.6] vsock/virtio: Validate length in packet header before skb_put()

category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICWO1M
CVE: CVE-2025-39718
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
When receiving a vsock packet in the guest, only the virtqueue buffer
size is validated prior to virtio_vsock_skb_rx_put(). Unfortunately,
virtio_vsock_skb_rx_put() uses the length from the packet header as the
length argument to skb_put(), potentially resulting in SKB overflow if
the host has gone wonky.
Validate the length as advertised by the packet header before calling
virtio_vsock_skb_rx_put().

category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICWGG2
CVE: CVE-2025-38691
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 9768797c219326699778fba9cd3b607b2f1e7950 ]
The error occurs on the third attempt to encode extents. When function
ext_tree_prepare_commit() reallocates a larger buffer to retry encoding
extents, the "layoutupdate_pages" page array is initialized only after the
retry loop. But ext_tree_free_commitdata() is called on every iteration
and tries to put pages in the array, thus dereferencing uninitialized
pointers.
An additional problem is that there is no limit on the maximum possible
buffer_size. When there are too many extents, the client may create a
layoutcommit that is larger than the maximum possible RPC size accepted
by the server.
During testing, we observed two typical scenarios. First, one memory page
for extents is enough when we work with small files, append data to the
end of the file, or preallocate extents before writing. But when we fill
a new large file without preallocating, the number of extents can be huge,
and counting the number of written extents in ext_tree_encode_commit()
does not help much. Since this number increases even more between
unlocking and locking of ext_tree, the reallocated buffer may not be
large enough again and again.

CVE: CVE-2025-38680

--------------------------------
commit 782b6a718651eda3478b1824b37a8b3185d2740c upstream.
The buffer length check before calling uvc_parse_format() only ensured
that the buffer has at least 3 bytes (buflen > 2), buf the function
accesses buffer[3], requiring at least 4 bytes.
This can lead to an out-of-bounds read if the buffer has exactly 3 bytes.
Fix it by checking that the buffer has at least 4 bytes in
uvc_parse_format().
