No, I don't think it's the same. This issue, AFAIK, causes default acls to
disappear from a directory, but does not crash the system. It's not really
a security issue, since it does not allow more rights on the files, but
less rights (removing default ACLS). Well, if a user can trigger it, it's
a DOS anyway.
I have not investigated the issue very deeply, but I can tell that it can
be fixed by applying the newer (>= 0.8.72) ACL patches from
To quote Andreas Gruenbacher, "This was fixed in version 0.8.72. The bug
was in function ext2_xattr_cmp and ext3_xattr_cmp: They did not compare
the e_name_index field."

I'll try 2.6.12, because with 2.6.8 (Sarge default 2.6 kernel) I have had
issues with USB2 controllers not being released by the BIOS to the
kernel's driver (which never happened with 2.4.x series) so I could not
use USB2 devices at all.
