[PATCH openEuler-22.03-LTS-SP1] nilfs2: propagate directory read errors from nilfs_find_entry()
by Baokun Li 20 Nov '24

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v5.10.228 commit c1d0476885d708a932980b0f28cd90d9bd71db39 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2YWL CVE: CVE-2024-50202 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 08cfa12adf888db98879dbd735bc741360a34168 upstream. Syzbot reported that a task hang occurs in vcs_open() during a fuzzing test for nilfs2. The root cause of this problem is that in nilfs_find_entry(), which searches for directory entries, ignores errors when loading a directory page/folio via nilfs_get_folio() fails. If the filesystem images is corrupted, and the i_size of the directory inode is large, and the directory page/folio is successfully read but fails the sanity check, for example when it is zero-filled, nilfs_check_folio() may continue to spit out error messages in bursts. Fix this issue by propagating the error to the callers when loading a page/folio fails in nilfs_find_entry(). The current interface of nilfs_find_entry() and its callers is outdated and cannot propagate error codes such as -EIO and -ENOMEM returned via nilfs_find_entry(), so fix it together.

[PATCH openEuler-1.0-LTS] nilfs2: propagate directory read errors from nilfs_find_entry()
by Baokun Li 20 Nov '24

20 Nov '24

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v4.19.323 commit bb857ae1efd3138c653239ed1e7aef14e1242c81 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2YWL CVE: CVE-2024-50202 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 08cfa12adf888db98879dbd735bc741360a34168 upstream. Syzbot reported that a task hang occurs in vcs_open() during a fuzzing test for nilfs2. The root cause of this problem is that in nilfs_find_entry(), which searches for directory entries, ignores errors when loading a directory page/folio via nilfs_get_folio() fails. If the filesystem images is corrupted, and the i_size of the directory inode is large, and the directory page/folio is successfully read but fails the sanity check, for example when it is zero-filled, nilfs_check_folio() may continue to spit out error messages in bursts. Fix this issue by propagating the error to the callers when loading a page/folio fails in nilfs_find_entry(). The current interface of nilfs_find_entry() and its callers is outdated and cannot propagate error codes such as -EIO and -ENOMEM returned via nilfs_find_entry(), so fix it together.

[PATCH OLK-5.10] mm,hwpoison: check mm when killing accessing process

From: Shuai Xue <xueshuai(a)linux.alibaba.com> mainline inclusion from mainline-v6.0 commit 77677cdbc2aa4b5d5d839562793d3d126201d18d category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB5LNL Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The GHES code calls memory_failure_queue() from IRQ context to queue work into workqueue and schedule it on the current CPU. Then the work is processed in memory_failure_work_func() by kworker and calls memory_failure(). When a page is already poisoned, commit a3f5d80ea401 ("mm,hwpoison: send SIGBUS with error virutal address") make memory_failure() call kill_accessing_process() that: - holds mmap locking of current->mm - does pagetable walk to find the error virtual address - and sends SIGBUS to the current process with error info. However, the mm of kworker is not valid, resulting in a null-pointer dereference. So check mm when killing the accessing process.
