Hi Greg / Sasha,
Can we please pull commit c3ed222745d9 ("NFSv4: Fix free of uninitialized nfs4_label on referral lookup.") into the 5.15.x tree? As far as I can tell, it should apply cleanly on top of v5.15.75.
Unfortunately, that commit also contains a bug, which requires us to pull in commit 4f40a5b55446 ("NFSv4: Add an fattr allocation to _nfs4_discover_trunking()"), which does not apply cleanly. I've attached a backported version to this email.
I'm seeing the Oops that this commit fixes when I do a NFSv4.2 mount from a NFS client running a 5.15.75 kernel against a server that has referrals configured. The reason is that commit d755ad8dc752 ("NFS: Create a new nfs_alloc_fattr_with_label() function") got pulled into v5.15.46 apparently as part of a dependency.
Both now queued up, thanks.
