hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9EEIG -------------------------------------- This commit fix the following errors in the code: 1. The arm_smmu_aux_attach_dev function returns an uncertain return value ret when all conditions are not met. In this case, the cd table is not initialized. Therefore, a new default exception value is added. 2. In arm_smmu_ecmdq_probe(), the parameter pre_addr is used in the loop but it is not initialed yet. Also, the parameter "ecmdq" is used before check if it is NULL.

[PATCH OLK-6.6] mm, fs: Add BPF_READAHEAD_OPTIMIZATION option for bpf readhead
by ZhaoLong Wang 07 Apr '24

07 Apr '24

hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I7Y9JD CVE: NA --------------------------- This patch introduces a new configuration option called BPF_READAHEAD_OPTIMIZATION, which is designed to optimize the read performance in Spark SQL scenarios using eBPF to implement a programmable kernel. The changes include: - Add CONFIG_BPF_READAHEAD_OPTIMIZATION to mm/Kconfig, which depends on CONFIG_TRACEPOINTS. - Add conditional compilation directives to fs/ext4/file.c, fs/read_write.c, fs/xfs/xfs_file.c, and include/linux/fs.h to include tracepoint-related headers and functions only when BPF_READAHEAD_OPTIMIZATION is enabled. - Miodify page_cache_sync_ra() in mm/readahead.c to disable forced readahead when BPF_READAHEAD_OPTIMIZATION is not enabled.

[PATCH openEuler-1.0-LTS] net: fec: fix the potential memory leak in fec_enet_init()
by Zhang Zekun 07 Apr '24

07 Apr '24

From: Fugang Duan <fugang.duan(a)nxp.com> stable inclusion from stable-5.10.42 commit 8ee7ef4a57a9e1228b6f345aaa70aa8951c7e9cd bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9BGVY CVE: CVE-2021-47150 ---------------------------------------------- If the memory allocated for cbd_base is failed, it should free the memory allocated for the queues, otherwise it causes memory leak. And if the memory allocated for the queues is failed, it can return error directly.

[PATCH V2 OLK-5.10] [Huawei] iommu/arm-smmu-v3: fix using uninitialized or unchecked symbol
by Zhang Zekun 07 Apr '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9EEIG -------------------------------------- This commit fix the following errors in the code: 1. The arm_smmu_aux_attach_dev function returns an uncertain return value ret when all conditions are not met. In this case, the cd table is not initialized. Therefore, a new default exception value is added. 2. In arm_smmu_ecmdq_probe(), the parameter pre_addr is used in the loop but it is not initialed yet. Also, the parameter "ecmdq" is used before check if it is NULL.

[PATCH OLK-6.6] mm, fs: Add BPF_READAHEAD_OPTIMIZATION option for bpf readhead
by ZhaoLong Wang 03 Apr '24

03 Apr '24

This patch introduces a new configuration option called BPF_READAHEAD_OPTIMIZATION, which is designed to optimize the read performance in Spark SQL scenarios using eBPF to implement a programmable kernel. The changes include: - Add CONFIG_BPF_READAHEAD_OPTIMIZATION to mm/Kconfig, which depends on CONFIG_TRACEPOINTS. - Add conditional compilation directives to fs/ext4/file.c, fs/read_write.c, fs/xfs/xfs_file.c, and include/linux/fs.h to include tracepoint-related headers and functions only when BPF_READAHEAD_OPTIMIZATION is enabled. - Miodify page_cache_sync_ra() in mm/readahead.c to disable forced readahead when BPF_READAHEAD_OPTIMIZATION is not enabled.

BTRFS: error (device vdc: state EA) in cleanup_transaction:2055: errno=-2 No such entry This happens because create_pending_snapshot() initializes the new root item as a copy of the source root item. This includes the refs field, which is 0 for a deleted subvolume. The call to btrfs_insert_root() therefore inserts a root with refs == 0. btrfs_get_new_fs_root() then finds the root and returns -ENOENT if refs == 0, which causes create_pending_snapshot() to abort. Fix it by checking the source root's refs before attempting the snapshot, but after locking subvol_sem to avoid racing with deletion.

[PATCH openEuler-1.0-LTS] scsi: hisi_sas: Update disk locked timeout to 7 seconds
by Xingui Yang 03 Apr '24

03 Apr '24

driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9DOVK CVE: NA --------------------------------------------------------------------------- The sata disk will be locked after the disk sends the DMA Setup frame until all data frame transmission is completed. The CFG_ICT_TIMER_STEP_TRSH register is used for sata disk to configure the step size of the timer which records the time when the disk is locked. The unit is 1us and the default step size is 150ms. If the disk is locked for more than 7 timer steps, the io to be sent to the disk will end abnormally. The current timeout is only about 1 second, it is easy to trigger IO abnormal end when the SATA hard disk returns data slowly. Adjust the timeout to 7 seconds based on ERC time of most disks.

[PATCH openEuler-1.0-LTS v2] tipc: wait and exit until all work queues are done

If the work queue is schedule to run after the TIPC module is removed, kernel will crash as the work queue function cleanup_beareri() code no longer exists when trying to invoke it. To fix it, this patch introduce a member wq_count in tipc_net to track the numbers of work queues in schedule, and wait and exit until all work queues are done in tipc_exit_net().
