NFSv4.1: Clear the old state by our client id before establishing a new lease

2015-03-04T02:52:30+00:00

If the call to exchange-id returns with the EXCHGID4_FLAG_CONFIRMED_R flag set, then that means our lease was established by a previous mount instance. Ensure that we detect this situation, and that we clear the state held by that mount. Reported-by: Jorge Mora Signed-off-by: Trond Myklebust

NFSv4.1: Clean up create_session

NFSv4.1: nfs4_destroy_session must call rpc_destroy_waitqueue

2014-02-01T20:13:39+00:00

There may still be timers active on the session waitqueues. Make sure that we kill them before freeing the memory. Cc: stable@vger.kernel.org # 3.12+ Signed-off-by: Trond Myklebust

When CONFIG_NFS_V4_1 is not enabled, "make C=2" emits this warning:

2013-09-04T16:26:30+00:00

linux/fs/nfs/nfs4session.c:337:6: warning: symbol 'nfs41_set_target_slotid' was not declared. Should it be static? Move nfs41_set_target_slotid() and nfs41_update_target_slotid() back behind CONFIG_NFS_V4_1, since, in the final revision of this work, they are used only in NFSv4.1 and later.

NFS: Add global helper for releasing slot table resources

2013-09-03T19:26:34+00:00

The nfs4_destroy_slot_tables() function is renamed to avoid confusion with the new helper. Signed-off-by: Chuck Lever Signed-off-by: Trond Myklebust

NFS: Enable slot table helpers for NFSv4.0

2013-09-03T19:26:33+00:00

I'd like to re-use NFSv4.1's slot table machinery for NFSv4.0 transport blocking. Re-organize some of nfs4session.c so the slot table code is built even when NFS_V4_1 is disabled. Signed-off-by: Chuck Lever Signed-off-by: Trond Myklebust

NFSv4.1: Add tracepoints for debugging slot table operations

2013-08-22T12:58:27+00:00

Add tracepoints to nfs41_setup_sequence and nfs41_sequence_done to track session and slot table state changes. Signed-off-by: Trond Myklebust

NFSv4.1 Increase NFS4_DEF_SLOT_TABLE_SIZE

2013-08-07T17:10:40+00:00

Increase NFS4_DEF_SLOT_TABLE_SIZE which is used as the client ca_maxreequests value in CREATE_SESSION. Current non-dynamic session slot server implementations use the client ca_maxrequests as a maximum slot number: 64 session slots can handle most workloads.

NFSv4.1 Refactor nfs4_init_session and nfs4_init_channel_attrs

2013-06-28T19:55:19+00:00

nfs4_init_session was originally written to be called prior to nfs4_init_channel_attrs, setting the session target_max response and request sizes that nfs4_init_channel_attrs would pay attention to. In the current code flow, nfs4_init_session, just like nfs4_init_ds_session for the data server case, is called after the session is all negotiated, and is actually used in a RECLAIM COMPLETE call to the server. Remove the un-needed fc_target_max response and request fields from nfs4_session and just set the max_resp_sz and max_rqst_sz in nfs4_init_channel_attrs.
