[PATCH kernel-4.19 1/2] fuse: truncate pagecache on atomic_o_trunc
by Yang Yingliang 22 Oct '21

22 Oct '21

From: Miklos Szeredi <mszeredi(a)redhat.com> mainline inclusion from mainline-5.14 commit 76224355db7570cbe6b6f75c8929a1558828dd55 category: bugfix bugzilla: 181107 CVE: NA --------------------------- fuse_finish_open() will be called with FUSE_NOWRITE in case of atomic O_TRUNC. This can deadlock with fuse_wait_on_page_writeback() in fuse_launder_page() triggered by invalidate_inode_pages2(). Fix by replacing invalidate_inode_pages2() in fuse_finish_open() with a truncate_pagecache() call. This makes sense regardless of FOPEN_KEEP_CACHE or fc->writeback cache, so do it unconditionally.

[PATCH kernel-4.19 1/4] ext4: check and update i_disksize properly
by Yang Yingliang 22 Oct '21

22 Oct '21

From: Zhang Yi <yi.zhang(a)huawei.com> mainline inclusion from mainline-5.15-rc4 commit 4df031ff5876d94b48dd9ee486ba5522382a06b2 category: perf bugzilla: NA CVE: NA --------------------------- After commit 3da40c7b0898 ("ext4: only call ext4_truncate when size <= isize"), i_disksize could always be updated to i_size in ext4_setattr(), and we could sure that i_disksize <= i_size since holding inode lock and if i_disksize < i_size there are delalloc writes pending in the range upto i_size. If the end of the current write is <= i_size, there's no need to touch i_disksize since writeback will push i_disksize upto i_size eventually. So we can switch to check i_size instead of i_disksize in ext4_da_write_end() when write to the end of the file. we also could remove ext4_mark_inode_dirty() together because we defer inode dirtying to generic_write_end() or ext4_da_write_inline_data_end().
