漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:f2fs: quota: fix to avoid warning in dquot_writeback_dquots()F2FS-fs (dm-59): checkpoint=enable has some unwritten data.------------[ cut here ]------------WARNING: CPU: 6 PID: 8013 at fs/quota/dquot.c:691 dquot_writeback_dquots+0x2fc/0x308pc : dquot_writeback_dquots+0x2fc/0x308lr : f2fs_quota_sync+0xcc/0x1c4Call trace:dquot_writeback_dquots+0x2fc/0x308f2fs_quota_sync+0xcc/0x1c4f2fs_write_checkpoint+0x3d4/0x9b0f2fs_issue_checkpoint+0x1bc/0x2c0f2fs_sync_fs+0x54/0x150f2fs_do_sync_file+0x2f8/0x814__f2fs_ioctl+0x1960/0x3244f2fs_ioctl+0x54/0xe0__arm64_sys_ioctl+0xa8/0xe4invoke_syscall+0x58/0x114checkpoint and f2fs_remount may race as below, resulting triggering warningin dquot_writeback_dquots().atomic write remount - do_remount - down_write(&sb->s_umount); - f2fs_remount- ioctl - f2fs_do_sync_file - f2fs_sync_fs - f2fs_write_checkpoint - block_operations - locked = down_read_trylock(&sbi->sb->s_umount) : fail to lock due to the write lock was held by remount - up_write(&sb->s_umount); - f2fs_quota_sync - dquot_writeback_dquots - WARN_ON_ONCE(!rwsem_is_locked(&sb->s_umount)) : trigger warning because s_umount lock was unlocked by remountIf checkpoint comes from mount/umount/remount/freeze/quotactl, caller ofcheckpoint has already held s_umount lock, calling dquot_writeback_dquots()in the context should be safe.So let s record task to sbi->umount_lock_holder, so that checkpoint canknow whether the lock has held in the context or not by checking currentw/ it.In addition, in order to not misrepresent caller of checkpoint, we shouldnot allow to trigger async checkpoint for those callers: mount/umount/remount/freeze/quotactl.
