[PATCH openEuler-5.10 000/107] NTFS read-write driver GPL

This patch adds NTFS Read-Write driver to fs/ntfs3. Having decades of expertise in commercial file systems development and huge test coverage, we at Paragon Software GmbH want to make our contribution to the Open Source Community by providing implementation of NTFS Read-Write driver for the Linux Kernel. This is fully functional NTFS Read-Write driver. Current version works with NTFS(including v3.1) and normal/compressed/sparse files and supports journal replaying. We plan to support this version after the codebase once merged, and add new features and fix bugs. For example, full journaling support over JBD will be added in later updates. v2: - patch splitted to chunks (file-wise) - build issues fixed - sparse and checkpatch.pl errors fixed - NULL pointer dereference on mkfs.ntfs-formatted volume mount fixed - cosmetics + code cleanup v3: - added acl, noatime, no_acs_rules, prealloc mount options - added fiemap support - fixed encodings support - removed typedefs - adapted Kernel-way logging mechanisms - fixed typos and corner-case issues v4: - atomic_open() refactored - code style updated - bugfixes v5: - nls/nls_alt mount options added - Unicode conversion fixes - Improved very fragmented files operations - logging cosmetics v6: - Security Descriptors processing changed added system.ntfs_security xattr to set SD - atomic_open() optimized - cosmetics Christophe JAILLET (2): fs/ntfs3: Remove a useless test in 'indx_find()' fs/ntfs3: Remove a useless shadowing variable Colin Ian King (4): fs/ntfs3: Fix various spelling mistakes fs/ntfs3: Fix integer overflow in multiplication fs/ntfs3: Remove redundant initialization of variable err fs/ntfs3: Fix a memory leak on object opts Dan Carpenter (5): fs/ntfs3: add checks for allocation failure fs/ntfs3: fix an error code in ntfs_get_acl_ex() fs/ntfs3: Fix error code in indx_add_allocate() fs/ntfs3: Potential NULL dereference in hdr_find_split() fs/ntfs3: Fix error handling in indx_insert_into_root() Gustavo A.

[PATCH openEuler-1.0-LTS 01/40] fuse: fix page stealing
by Yang Yingliang 27 Jan '22

27 Jan '22

From: Miklos Szeredi <mszeredi(a)redhat.com> stable inclusion from linux-4.19.219 commit 65f1f3eb09a3907c5f5edaff6c473b99e49e6020 -------------------------------- commit 712a951025c0667ff00b25afc360f74e639dfabe upstream. It is possible to trigger a crash by splicing anon pipe bufs to the fuse device. The reason for this is that anon_pipe_buf_release() will reuse buf->page if the refcount is 1, but that page might have already been stolen and its flags modified (e.g. PG_lru added). This happens in the unlikely case of fuse_dev_splice_write() getting around to calling pipe_buf_release() after a page has been stolen, added to the page cache and removed from the page cache. Fix by calling pipe_buf_release() right after the page was inserted into the page cache. In this case the page has an elevated refcount so any release function will know that the page isn't reusable.

[PATCH openEuler-5.10 01/47] net: add and use skb_unclone_keeptruesize() helper
by Zheng Zengkai 27 Jan '22

27 Jan '22

From: Eric Dumazet <edumazet(a)google.com> mainline inclusion from mainline-v5.16-rc1 commit c4777efa751d293e369aec464ce6875e957be255 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4RYXI CVE: NA -------------------------------- While commit 097b9146c0e2 ("net: fix up truesize of cloned skb in skb_prepare_for_shift()") fixed immediate issues found when KFENCE was enabled/tested, there are still similar issues, when tcp_trim_head() hits KFENCE while the master skb is cloned. This happens under heavy networking TX workloads, when the TX completion might be delayed after incoming ACK. This patch fixes the WARNING in sk_stream_kill_queues when sk->sk_mem_queued/sk->sk_forward_alloc are not zero.
