Bug description:
I've seen this happen twice in the last 8 days on an NFS server
running Ubuntu precise and kernels 3.2.0-65.98-generic (on the first
occasion) and 3.2.0-67.101-generic (the second time), amd64. This
never happened before in several months of operation; until 2014-07-01
this server was running an older 3.2.0 kernel.
When this error appears in the logs, the system stops answering NFS
RPCs (e.g., "rpcinfo -u localhost nfs 3" hangs) and a reboot is
necessary to restore NFS service. A more detailed stack trace follows.
Looking at the source code (fs/nfsd/vfs.c:set_nfsv4_acl_one()) I see
that the call posix_acl_xattr_size(pacl->a_count) is not preceded by a
check that pacl != NULL. Could this be related to the following entry
in the changelog for 3.2.0-65.98?
