btrfs: compare the correct fsid/metadata_uuid in btrfs_validate_super
stable inclusion from stable-v5.10.197 commit df380d6f5c06c7b8e5fd06819aa0b7fe1175d32b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I96Q8P Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=df380d6f5c06c7b8e5fd06819aa0b7fe1175d32b -------------------------------- [ Upstream commit 6bfe3959 ] The function btrfs_validate_super() should verify the metadata_uuid in the provided superblock argument. Because, all its callers expect it to do that. Such as in the following stacks: write_all_supers() sb = fs_info->super_for_commit; btrfs_validate_write_super(.., sb) btrfs_validate_super(.., sb, ..) scrub_one_super() btrfs_validate_super(.., sb, ..) And check_dev_super() btrfs_validate_super(.., sb, ..) However, it currently verifies the fs_info::super_copy::metadata_uuid instead. Fix this using the correct metadata_uuid in the superblock argument. CC: stable@vger.kernel.org # 5.4+ Reviewed-by:Johannes Thumshirn <johannes.thumshirn@wdc.com> Tested-by:
