| H A D | symlink.c | 8c4bca10 Fri Jul 02 01:53:47 CDT 2021 Eric Biggers <ebiggers@google.com> ext4: report correct st_size for encrypted symlinks
The stat() family of syscalls report the wrong size for encrypted
symlinks, which has caused breakage in several userspace programs.
Fix this by calling fscrypt_symlink_getattr() after ext4_getattr() for
encrypted symlinks. This function computes the correct size by reading
and decrypting the symlink target (if it's not already cached).
For more details, see the commit which added fscrypt_symlink_getattr().
