An error was introduced while porting genpatches's 1500_XATTR_USER_PREFIX.patch to the 6.1 branch. This results in the following issue: $ touch /tmp/testfile $ setfattr -n user.foo -v bar /tmp/testfile #succeeds when it shouldn't $ setfattr -n user.user.foo -v bar /tmp/testfile setfattr: /tmp/testfile: Operation not supported So the restrictions apply to user.user.* instead of user.* The problem is in the following hunk: +--- a/mm/shmem.c 2022-11-22 05:57:29.011626215 -0500 ++++ b/mm/shmem.c 2022-11-22 06:03:33.165939400 -0500 +@@ -3297,6 +3297,14 @@ static int shmem_xattr_handler_set(const + struct shmem_inode_info *info = SHMEM_I(inode); + int err; + ++ ++ if (!strncmp(name, XATTR_USER_PREFIX, XATTR_USER_PREFIX_LEN)) { ++ if (strcmp(name, XATTR_NAME_PAX_FLAGS)) ++ return -EOPNOTSUPP; ++ if (size > 8) ++ return -EINVAL; ++ } ++ + name = xattr_full_name(handler, name); + err = simple_xattr_set(&info->xattrs, name, value, size, flags, NULL); + if (!err) { To fix the issue, the inserted if statement must be moved after the "name = xattr_full_name(handler, name);" line. As noted above, the error was introduced in the 6.1 branch of genpatches; 6.2 and 6.3 are affected, too.
