Subject: [Regression] "SUNRPC: Add "@len" parameter to gss_unwrap()" breaks NFS Kerberos on upstream stable 5.4.y
Date: Wed, 15 Jul 2020 22:48:06 +0800 [thread overview]
Message-ID: <309E203B-8818-4E33-87F0-017E127788E2@canonical.com> (raw)
Hi,
Multiple users reported NFS causes NULL pointer dereference [1] on Ubuntu, due to commit "SUNRPC: Add "@len" parameter to gss_unwrap()" and commit "SUNRPC: Fix GSS privacy computation of auth->au_ralign".
The same issue happens on upstream stable 5.4.y branch.
The mainline kernel doesn't have this issue though.
Should we revert them? Or is there any missing commits need to be backported to v5.4?
