NFSd: set nfsd_serv to NULL after service destruction

2012-10-02T17:40:01+00:00

commit 57c8b13e3cd0f94944c9691ce7f58e5fcef8a12d upstream. In nfsd_destroy(): if (destroy) svc_shutdown_net(nfsd_serv, net); svc_destroy(nfsd_server); svc_shutdown_net(nfsd_serv, net) calls nfsd_last_thread(), which sets nfsd_serv to NULL, causing a NULL dereference on the following line.

nfsd4: fix security flavor of NFSv4.0 callback

2012-09-14T16:59:25+00:00

commit 39307655a1effa8d913bba054c0e985bfaca808c upstream. Commit d5497fc693a446ce9100fcf4117c3f795ddfd0d2 "nfsd4: move rq_flavor into svc_cred" forgot to remove cl_flavor from the client, leaving two places (cl_flavor and cl_cred.cr_flavor) for the flavor to be stored. After that patch, the latter was the one that was updated, but the former was the one that the callback used. Symptoms were a long delay on utime(). This is because the utime() generated a setattr which recalled a delegation, but the cb_recall was ignored by the client because it had the wrong security flavor.

nfsd4: our filesystems are normally case sensitive

2012-08-09T15:23:11+00:00

commit 2930d381d22b9c56f40dd4c63a8fa59719ca2c3c upstream. Actually, xfs and jfs can optionally be case insensitive; we'll handle that case in later patches. Signed-off-by: J. Bruce Fields Signed-off-by: Greg Kroah-Hartman

nfsd4: BUG_ON(!is_spin_locked()) no good on UP kernels

2012-06-14T17:54:08+00:00

Most frequent symptom was a BUG triggering in expire_client, with the server locking up shortly thereafter. Introduced by 508dc6e110c6dbdc0bbe84298ccfe22de7538486 "nfsd41: free_session/free_client must be called under the client_lock". Cc: stable@kernel.org Cc: Benny Halevy Signed-off-by: J. Bruce Fields

nfsd4: fix, consolidate client_has_state

2012-06-01T00:30:39+00:00

Whoops: first, I reimplemented the already-existing has_resources without noticing; second, I got the test backwards. I did pick a better name, though. Combine the two.... Signed-off-by: J. Bruce Fields

nfsd4: don't remove rebooted client record until confirmation

2012-06-01T00:30:34+00:00

In the NFSv4.1 client-reboot case we're currently removing the client's previous state in exchange_id. That's wrong--we should be waiting till the confirming create_session. Signed-off-by: J. Bruce Fields
