[PATCH OLK-6.6] xfs: split xfs_mod_freecounter
by Zizhi Wo 02 Dec '24

02 Dec '24

From: Christoph Hellwig <hch(a)lst.de> mainline inclusion from mainline-v6.10-rc1 commit f30f656e25eb72c4309e76b16fa45062e183a2ee category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB7V02 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- xfs_mod_freecounter has two entirely separate code paths for adding or subtracting from the free counters. Only the subtract case looks at the rsvd flag and can return an error. Split xfs_mod_freecounter into separate helpers for subtracting or adding the freecounter, and remove all the impossible to reach error handling for the addition case.

[PATCH OLK-5.10] xfs: Fix data overflow in xfs_mod_fdblocks()
by Zizhi Wo 02 Dec '24

02 Dec '24

Offering: HULK hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB7V02 -------------------------------- If the xfs reserve block related ioctl takes a large input value, the input reserved size is still assigned to mp->m_resblks in xfs_reserve_blocks() even if the requested size is larger than the total free size in the filesystem. This is because the subsequent xfs_mod_fdblocks() will handle the adjustment. However, in the current code, xfs_mod_fdblocks() calculates mp->m_resblks - mp->m_resblks_avail and casts the result to a long long type, while both mp->m_resblks and mp->m_resblks_avail are of type unsigned long long. If the difference between these two values is very large, and the most significant bit (MSB) is set to 1 (indicating a large unsigned value), the result of the cast becomes a large negative value. This causes mp->m_fdblocks to be updated to a very large value. As a result, xfs will incorrectly determine that there is always free space during foreground writes, while background writebacks may fail due to lack of space. Modify the relevant data types in xfs_mod_fdblocks() to address this issue.

[PATCH OLK-6.6] nfs: Ensure write and flush consume writeback errors
by Yang Erkun 30 Nov '24

30 Nov '24

From: Wang Zhaolong <wangzhaolong1(a)huawei.com> HULK inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB7MNY -------------------------------- When the file is closed and the ->flush is executed, the writeback error is not consumed. As a result, when the file is written next time, the writeback error still exists, causing a new write failure. Another problem is that in the write process, only special writeback error codes such as -EDQUOT, -EFBIG, and -ENOSPC are detected, and the error codes are consumed. In this case, other error codes may be left. The writeback error code should be consumed unconditionally in the write(), fsync(), and close() to avoid sampling residual expired codes that are left over from the last invoking. In the fsync process, the error code can be consumed. Therefore, this patch ensures that write and flush can consume error codes.

[PATCH OLK-5.10 00/20] blk-mq/scsi: tracking device queue depth via sbitmap
by Zheng Qixing 29 Nov '24

29 Nov '24

Linux mainline-5.13 uses sbitmap to track the queue depth of SCSI devices. This patch set backports the mainline patches to OLK-5.10 and fixes some KABI issues. Tests on scsi_debug show that this method can improve IO performance by more than 30%.

[PATCH OLK-6.6] [Backport] ext4: avoid remount errors with 'abort' mount option
by Yongjian Sun 29 Nov '24

29 Nov '24

From: Jan Kara <jack(a)suse.cz> mainline inclusion from mainline-v6.12-rc3 commit 76486b104168ae59703190566e372badf433314b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2YWS CVE: CVE-2024-50191 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When we remount filesystem with 'abort' mount option while changing other mount options as well (as is LTP test doing), we can return error from the system call after commit d3476f3dad4a ("ext4: don't set SB_RDONLY after filesystem errors") because the application of mount option changes detects shutdown filesystem and refuses to do anything. The behavior of application of other mount options in presence of 'abort' mount option is currently rather arbitary as some mount option changes are handled before 'abort' and some after it. Move aborting of the filesystem to the end of remount handling so all requested changes are properly applied before the filesystem is shutdown to have a reasonably consistent behavior.

As qos_overload_timer_handler() requires rq lock, while the cpu hotplug attached firstly and waiting for the qos_timer handling, This can cause Hard LOCKUP like: [359230.788754] Call trace: [359230.788755] hrtimer_active+0x7c/0xec [359230.788757] hrtimer_cancel+0x3c/0x60 [359230.788758] unthrottle_qos_cfs_rqs+0xbc/0x110 [359230.788760] unthrottle_offline_cfs_rqs+0x40/0x150 [359230.788762] rq_offline_fair+0x60/0x70 [359230.788764] set_rq_offline.part.0+0x54/0xf4 [359230.788765] set_rq_offline+0x34/0x44 [359230.788767] rq_attach_root+0x1e8/0x260 [359230.788768] cpu_attach_domain+0x244/0x430 [359230.788770] detach_destroy_domains+0xbc/0x140 [359230.788772] partition_sched_domains_locked+0x23c/0x314 [359230.788774] rebuild_sched_domains_locked+0x1f0/0x270 [359230.788776] cpuset_hotplug_workfn+0x514/0x74c [359230.788777] process_one_work+0x34c/0x800 [359230.788779] worker_thread+0xa8/0x500 [359230.788780] kthread+0x1e0/0x220 [359230.788782] ret_from_fork+0x10/0x18 [359230.788783] Kernel panic - not syncing: Hard LOCKUP Fix it by switch to use __unthrottle_qos_cfs_rqs(), instead of unthrottle_qos_cfs_rqs() in unthrottle_offline_cfs_rqs, so that it will not trigger cancel_qos_timer() when cpu hotplug offline.

The mentioned data is observed on the wire. This patch uses skb_put_padto() to pad Ethernet frames properly. The mentioned function zeroes the expanded buffer. In case the packet cannot be padded it is silently dropped. Statistics are also not incremented. This driver does not support statistics in the old 32-bit format or the new 64-bit format. These will be added in the future. In its current form, the patch should be easily backported to stable versions. Ethernet MACs on Amazon-SE and Danube cannot do padding of the packets in hardware, so software padding must be applied.

The commit b8c43360f6e4 ("net: stmmac: No need to calculate speed divider when offload is disabled") allows the "port_transmit_rate_kbps" to be set to a value of 0, which is then passed to the "div_s64" function when tc-cbs is disabled. This leads to a zero-division error. When tc-cbs is disabled, the idleslope, sendslope, and credit values the credit values are not required to be configured.

[PATCH openEuler-22.03-LTS-SP1] wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmit
by Wang Liang 29 Nov '24

29 Nov '24

From: Toke Høiland-Jørgensen <toke(a)redhat.com> stable inclusion from stable-v5.10.227 commit b02eb7c86ff2ef1411c3095ec8a52b13f68db04f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYRA2 CVE: CVE-2024-49938 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 94745807f3ebd379f23865e6dab196f220664179 ] Syzbot points out that skb_trim() has a sanity check on the existing length of the skb, which can be uninitialised in some error paths. The intent here is clearly just to reset the length to zero before resubmitting, so switch to calling __skb_set_length(skb, 0) directly. In addition, __skb_set_length() already contains a call to skb_reset_tail_pointer(), so remove the redundant call. The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similar usage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it.

However, the ath11k_dp_process_rx() function access ath11k_soc_dp_stats::hal_reo_error using the REO destination SRNG ring ID, which is incorrect. SRNG ring ID differ from normal ring ID, and this usage leads to out-of-bounds array access. To fix this issue, modify ath11k_dp_process_rx() to use the normal ring ID directly instead of the SRNG ring ID to avoid out-of-bounds array access.

Unfortunately syzbot can crash a host rather easily using a TBF + SFQ combination, with an STAB on SFQ [1] We can't support TCA_STAB on arbitrary level, this would require to maintain per-qdisc storage.

The mentioned data is observed on the wire. This patch uses skb_put_padto() to pad Ethernet frames properly. The mentioned function zeroes the expanded buffer. In case the packet cannot be padded it is silently dropped. Statistics are also not incremented. This driver does not support statistics in the old 32-bit format or the new 64-bit format. These will be added in the future. In its current form, the patch should be easily backported to stable versions. Ethernet MACs on Amazon-SE and Danube cannot do padding of the packets in hardware, so software padding must be applied.

The commit b8c43360f6e4 ("net: stmmac: No need to calculate speed divider when offload is disabled") allows the "port_transmit_rate_kbps" to be set to a value of 0, which is then passed to the "div_s64" function when tc-cbs is disabled. This leads to a zero-division error. When tc-cbs is disabled, the idleslope, sendslope, and credit values the credit values are not required to be configured.

Otherwise, next time when calling sctp_inet_listen(), if sctp_sk(sk)->reuse is already set via setsockopt(SCTP_REUSE_PORT), sctp_sk(sk)->bind_hash will be dereferenced as sk_state is LISTENING, which causes a crash as bind_hash is NULL.

[PATCH OLK-5.10] wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmit

From: Toke Høiland-Jørgensen <toke(a)redhat.com> stable inclusion from stable-v5.10.227 commit b02eb7c86ff2ef1411c3095ec8a52b13f68db04f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYRA2 CVE: CVE-2024-49938 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 94745807f3ebd379f23865e6dab196f220664179 ] Syzbot points out that skb_trim() has a sanity check on the existing length of the skb, which can be uninitialised in some error paths. The intent here is clearly just to reset the length to zero before resubmitting, so switch to calling __skb_set_length(skb, 0) directly. In addition, __skb_set_length() already contains a call to skb_reset_tail_pointer(), so remove the redundant call. The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similar usage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it.

However, the ath11k_dp_process_rx() function access ath11k_soc_dp_stats::hal_reo_error using the REO destination SRNG ring ID, which is incorrect. SRNG ring ID differ from normal ring ID, and this usage leads to out-of-bounds array access. To fix this issue, modify ath11k_dp_process_rx() to use the normal ring ID directly instead of the SRNG ring ID to avoid out-of-bounds array access.

[PATCH OLK-5.10 00/21] blk-mq/scsi: tracking device queue depth via sbitmap
by Zheng Qixing 29 Nov '24

29 Nov '24

Linux mainline-5.13 uses sbitmap to track the queue depth of SCSI devices. This patch set backports the mainline patches to OLK-5.10 and fixes some KABI issues.

[PATCH OLK-6.6 V1] media: dvbdev: fix the logic when DVB_DYNAMIC_MINORS is not set
by Zicheng Qu 28 Nov '24

28 Nov '24

From: Mauro Carvalho Chehab <mchehab+huawei(a)kernel.org> stable inclusion from stable-v6.6.63 commit db12e874e1a202206c734d89920e4aa9e290efa2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5KR8 CVE: CVE-2024-53063 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a4aebaf6e6efff548b01a3dc49b4b9074751c15b upstream. When CONFIG_DVB_DYNAMIC_MINORS, ret is not initialized, and a semaphore is left at the wrong state, in case of errors. Make the code simpler and avoid mistakes by having just one error check logic used weather DVB_DYNAMIC_MINORS is used or not.

[PATCH OLK-5.10] arm64: mm: Stop use spinlock during pbha early init
by Wupeng Ma 28 Nov '24

28 Nov '24

From: Ma Wupeng <mawupeng1(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I96IZH -------------------------------- During early_pbha_init() in __primary_switched(), debug spinlock related function is not fully initialized. This will lead to kernel unable to boot with CONFIG_LOCK_STAT=y or related configs. Since kernel is running with only one cpu during startup, there is no need to use lock.

[PATCH openEuler-1.0-LTS] crypto: pcrypt - Call crypto layer directly when padata_do_parallel() return -EBUSY

mainline inclusion from mainline-v6.13-rc1 commit 662f2f13e66d3883b9238b0b96b17886179e60e2 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7RZMT Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Since commit 8f4f68e788c3 ("crypto: pcrypt - Fix hungtask for PADATA_RESET"), the pcrypt encryption and decryption operations return -EAGAIN when the CPU goes online or offline. In alg_test(), a WARN is generated when pcrypt_aead_decrypt() or pcrypt_aead_encrypt() returns -EAGAIN, the unnecessary panic will occur when panic_on_warn set 1.
