From: Wang Hai <wanghai38(a)huawei.com> mainline inclusion from mainline-v6.12-rc4 commit fca6caeb4a61d240f031914413fcc69534f6dc03 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2SU3 CVE: CVE-2024-50153 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------ There is a null-ptr-deref issue reported by KASAN: BUG: KASAN: null-ptr-deref in target_alloc_device+0xbc4/0xbe0 [target_core_mod] ... kasan_report+0xb9/0xf0 target_alloc_device+0xbc4/0xbe0 [target_core_mod] core_dev_setup_virtual_lun0+0xef/0x1f0 [target_core_mod] target_core_init_configfs+0x205/0x420 [target_core_mod] do_one_initcall+0xdd/0x4e0 ... entry_SYSCALL_64_after_hwframe+0x76/0x7e In target_alloc_device(), if allocing memory for dev queues fails, then dev will be freed by dev->transport->free_device(), but dev->transport is not initialized at that time, which will lead to a null pointer reference problem. Fixing this bug by freeing dev with hba->backend->ops->free_device().

[PATCH OLK-5.10] RDMA/hns: Fix the valid QP bank set to improve performance
by Chengchang Tang 14 Nov '24

14 Nov '24

From: wenglianfa <wenglianfa(a)huawei.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB2HJE ---------------------------------------------------------------------- QP banks 0, 1, 4, and 5 use one HW FIFO, while QP banks 2, 3, 6, and 7 use another. Currently, if HNS_ROCE_CAP_FLAG_LIMIT_BANK is set, only QP banks 0, 1, 4, and 5 are used, resulting in a single HW FIFO being utilized. Instead, it is proposed to use QP banks 0, 1, 6, and 7 to leverage different FIFOs and improve performance.

The problem arises when a phy control response comes late. After 300 ms the pm8001_phy_control() function returns and the passed enable_completion stack address is no longer valid. Late phy control response invokes complete() on a dangling enable_completion pointer which leads to a kernel crash.

[PATCH OLK-5.10] xfs: Fix missing interval for missing_owner in xfs fsmap

mainline inclusion from mainline-v6.11-rc6 commit ca6448aed4f10ad88eba79055f181eb9a589a7b3 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB42M2 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- In the fsmap query of xfs, there is an interval missing problem: [root@fedora ~]# xfs_io -c 'fsmap -vvvv' /mnt EXT: DEV BLOCK-RANGE OWNER FILE-OFFSET AG AG-OFFSET TOTAL 0: 253:16 [0..7]: static fs metadata 0 (0..7) 8 1: 253:16 [8..23]: per-AG metadata 0 (8..23) 16 2: 253:16 [24..39]: inode btree 0 (24..39) 16 3: 253:16 [40..47]: per-AG metadata 0 (40..47) 8 4: 253:16 [48..55]: refcount btree 0 (48..55) 8 5: 253:16 [56..103]: per-AG metadata 0 (56..103) 48 6: 253:16 [104..127]: free space 0 (104..127) 24 ...... BUG: [root@fedora ~]# xfs_io -c 'fsmap -vvvv -d 104 107' /mnt [root@fedora ~]# Normally, we should be able to get [104, 107), but we got nothing. The problem is caused by shifting. The query for the problem-triggered scenario is for the missing_owner interval (e.g. freespace in rmapbt/ unknown space in bnobt), which is obtained by subtraction (gap). For this scenario, the interval is obtained by info->last. However, rec_daddr is calculated based on the start_block recorded in key[1], which is converted by calling XFS_BB_TO_FSBT. Then if rec_daddr does not exceed info->next_daddr, which means keys[1].fmr_physical >> (mp)->m_blkbb_log <= info->next_daddr, no records will be displayed. In the above example, 104 >> (mp)->m_blkbb_log = 12 and 107 >> (mp)->m_blkbb_log = 12, so the two are reduced to 0 and the gap is ignored: before calculate ----------------> after shifting 104(st) 107(ed) 12(st/ed) |---------| | sector size block size Resolve this issue by introducing the "end_daddr" field in xfs_getfsmap_info. This records |key[1].fmr_physical + key[1].length| at the granularity of sector. If the current query is the last, the rec_daddr is end_daddr to prevent missing interval problems caused by shifting. We only need to focus on the last query, because xfs disks are internally aligned with disk blocksize that are powers of two and minimum 512, so there is no problem with shifting in previous queries. After applying this patch, the above problem have been solved: [root@fedora ~]# xfs_io -c 'fsmap -vvvv -d 104 107' /mnt EXT: DEV BLOCK-RANGE OWNER FILE-OFFSET AG AG-OFFSET TOTAL 0: 253:16 [104..106]: free space 0 (104..106) 3 Fixes: e89c041338ed ("xfs: implement the GETFSMAP ioctl") Signed-off-by: Zizhi Wo <wozizhi(a)huawei.com> Reviewed-by: Darrick J.

[PATCH OLK-5.10 V1] staging: iio: frequency: ad9834: Validate frequency parameter value

In ad9834_write_frequency() clk_get_rate() can return 0. In such case ad9834_calc_freqreg() call will lead to division by zero. Checking 'if (fout > (clk_freq / 2))' doesn't protect in case of 'fout' is 0. ad9834_write_frequency() is called from ad9834_write(), where fout is taken from text buffer, which can contain any value.

BUG: [root@fedora ~]# xfs_io -c 'fsmap -vvvv -d 104 107' /mnt [root@fedora ~]# Normally, we should be able to get [104, 107), but we got nothing. The problem is caused by shifting. The query for the problem-triggered scenario is for the missing_owner interval (e.g. freespace in rmapbt/ unknown space in bnobt), which is obtained by subtraction (gap). For this scenario, the interval is obtained by info->last. However, rec_daddr is calculated based on the start_block recorded in key[1], which is converted by calling XFS_BB_TO_FSBT. Then if rec_daddr does not exceed info->next_daddr, which means keys[1].fmr_physical >> (mp)->m_blkbb_log <= info->next_daddr, no records will be displayed. In the above example, 104 >> (mp)->m_blkbb_log = 12 and 107 >> (mp)->m_blkbb_log = 12, so the two are reduced to 0 and the gap is ignored: before calculate ----------------> after shifting 104(st) 107(ed) 12(st/ed) |---------| | sector size block size Resolve this issue by introducing the "end_daddr" field in xfs_getfsmap_info. This records |key[1].fmr_physical + key[1].length| at the granularity of sector. If the current query is the last, the rec_daddr is end_daddr to prevent missing interval problems caused by shifting. We only need to focus on the last query, because xfs disks are internally aligned with disk blocksize that are powers of two and minimum 512, so there is no problem with shifting in previous queries. After applying this patch, the above problem have been solved: [root@fedora ~]# xfs_io -c 'fsmap -vvvv -d 104 107' /mnt EXT: DEV BLOCK-RANGE OWNER FILE-OFFSET AG AG-OFFSET TOTAL 0: 253:16 [104..106]: free space 0 (104..106) 3 Fixes: e89c041338ed ("xfs: implement the GETFSMAP ioctl") Signed-off-by: Zizhi Wo <wozizhi(a)huawei.com> Reviewed-by: Darrick J.

From: Wang Hai <wanghai38(a)huawei.com> stable inclusion from stable-v5.10.158 commit b775f37d943966f6f77dca402f5a9dedce502c25 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYREC Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 45605c75c52c7ae7bfe902214343aabcfe5ba0ff ] In e100_xmit_prepare(), if we can't map the skb, then return -ENOMEM, so e100_xmit_frame() will return NETDEV_TX_BUSY and the upper layer will resend the skb. But the skb is already freed, which will cause UAF bug when the upper layer resends the skb. Remove the harmful free.

Then Nicolai Stange found more places in aoe have potential use-after-free problem with tx(). e.g. revalidate(), aoecmd_ata_rw(), resend(), probe() and aoecmd_cfg_rsp(). Those functions also use aoenet_xmit() to push packet to tx queue. So they should also use dev_hold() to increase the refcnt of skb->dev. On the other hand, moving dev_put() to tx() causes that the refcnt of skb->dev be reduced to a negative value, because corresponding dev_hold() are not called in revalidate(), aoecmd_ata_rw(), resend(), probe(), and aoecmd_cfg_rsp().

[PATCH OLK-5.10V1] staging: iio: frequency: ad9834: Validate frequency parameter value
by Zicheng Qu 14 Nov '24

14 Nov '24

From: Aleksandr Mishin <amishin(a)t-argos.ru> stable inclusion from stable-v5.10.226 commit 41cc91e3138fe52f8da92a81bebcd0e6cf488c53 category: bugfix bugzilla: IAVU8A CVE: CVE-2024-47663 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit b48aa991758999d4e8f9296c5bbe388f293ef465 upstream. In ad9834_write_frequency() clk_get_rate() can return 0. In such case ad9834_calc_freqreg() call will lead to division by zero. Checking 'if (fout > (clk_freq / 2))' doesn't protect in case of 'fout' is 0. ad9834_write_frequency() is called from ad9834_write(), where fout is taken from text buffer, which can contain any value. Modify parameters checking. Found by Linux Verification Center (linuxtesting.org) with SVACE.
