From: Chuck Lever <chuck.lever(a)oracle.com> mainline inclusion from mainline-v5.17-rc4 commit 0cb4d23ae08c48f6bf3c29a8e5c4a74b8388b960 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IADG80 CVE: CVE-2022-48827 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Dan Aloni reports: > Due to commit 8cfb9015280d ("NFS: Always provide aligned buffers to > the RPC read layers") on the client, a read of 0xfff is aligned up > to server rsize of 0x1000. > > As a result, in a test where the server has a file of size > 0x7fffffffffffffff, and the client tries to read from the offset > 0x7ffffffffffff000, the read causes loff_t overflow in the server > and it returns an NFS code of EINVAL to the client. The client as > a result indefinitely retries the request. The Linux NFS client does not handle NFS?ERR_INVAL, even though all NFS specifications permit servers to return that status code for a READ. Instead of NFS?ERR_INVAL, have out-of-range READ requests succeed and return a short result. Set the EOF flag in the result to prevent the client from retrying the READ request. This behavior appears to be consistent with Solaris NFS servers. Note that NFSv3 and NFSv4 use u64 offset values on the wire. These must be converted to loff_t internally before use -- an implicit type cast is not adequate for this purpose. Otherwise VFS checks against sb->s_maxbytes do not work properly.

[PATCH openEuler-1.0-LTS] net: ieee802154: at86rf230: Stop leaking skb's
by Zhengchao Shao 23 Jul '24

23 Jul '24

From: Miquel Raynal <miquel.raynal(a)bootlin.com> stable inclusion from stable-v4.19.231 commit 6312f6a53fd3ea38125dcaca5e3c9aa7d8a60cf7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IADG4I CVE: CVE-2022-48794 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… --------------------------- [ Upstream commit e5ce576d45bf72fd0e3dc37eff897bfcc488f6a9 ] Upon error the ieee802154_xmit_complete() helper is not called. Only ieee802154_wake_queue() is called manually. In the Tx case we then leak the skb structure. Free the skb structure upon error before returning when appropriate. As the 'is_tx = 0' cannot be moved in the complete handler because of a possible race between the delay in switching to STATE_RX_AACK_ON and a new interrupt, we introduce an intermediate 'was_tx' boolean just for this purpose. There is no Fixes tag applying here, many changes have been made on this area and the issue kind of always existed.

While fixing it I noticed that nothing prevents a vlan to be freed while walking the list from the same path (br forward delay timer). Fix the rcu usage and also make sure we are not accessing freed memory by making br_mst_vlan_set_state use rcu read lock.

[PATCH OLK-6.6] mm: filemap: optimize semantic when thp_exec_enabled is set to 3
by Nanyong Sun 22 Jul '24

22 Jul '24

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAEOV4 CVE: NA -------------------------------- When thp_exec_enabled is set to 3, try PMD mapping THP first, if failed, then try mTHP like cont-64K on ARM64. The previous implementation use hugepage_madvise() in try_enable_file_exec_thp() and it will always set VM_HUGEPAGE to vm_flags, so we lost this semantic, let's check PMD_ORDER by thp_vma_allowable_order() to correct the semantic. And now the khugepaged_enter_vma() step in hugepage_madvise() is missing, this is OK because the process is already entered in khugepaged after this commit 613bec092fe7 ("mm: mmap: register suitable readonly file vmas for khugepaged").
