[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.
