Replace use of rpc_call_setup() with rpc_init_task(), and in cases where we need to initialise task->tk_action, with rpc_call_start(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

We want the default scheduling priority (priority == 0) to remain RPC_PRIORITY_NORMAL. Also ensure that the priority wait queue scheduling is per process id instead of sometimes being per thread, and sometimes being per inode. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

If we've disconnected from the server, rather than the other way round, then it makes little sense to wait 3 seconds before reconnecting. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

Trond Myklebust authored
xprt_disconnect() should really only be called when the transport shutdown is completed, and it is time to wake up any pending tasks. Rename it to xprt_disconnect_done() in order to reflect the semantical change. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
-
Trond Myklebust authored
Move the calls to xprt_disconnect() over to xprt_force_disconnect() in order to enable the transport layer to manage the state of the XPRT_CONNECTED flag. Ditto in xs_tcp_read_fraghdr(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
-
Trond Myklebust authored
The transport layer should do that itself whenever appropriate. Note that the RDMA transport already assumes that it needs to call xprt_disconnect in xprt_rdma_close(). For TCP sockets, we want to call xprt_disconnect() only after the connection has been closed by both ends. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
-
Trond Myklebust authored
By using shutdown() rather than close() we allow the RPC client to wait for the TCP close handshake to complete before we start trying to reconnect using the same port. We use shutdown(SHUT_WR) only instead of shutting down both directions, however we wait until the server has closed the connection on its side.

Add an xprt->state bit to enable the TCP ->state_change() method to signal whether or not the TCP connection is in the process of closing down. This will to be used by the reconnection logic in a separate patch. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
-
Trond Myklebust authored
Currently the TCP rebinding logic assumes that if we're not using a reserved port, then we don't need to reconnect on the same port if a disconnection event occurs. This breaks most RPC duplicate reply cache implementations. Also take into account the fact that xprt_min_resvport and xprt_max_resvport may change while we're reconnecting, since the user may change them at any time via the sysctls. Ensure that we check the port boundaries every time we loop in xs_bind4/xs_bind6. Also ensure that if the boundaries change, we only scan the ports a maximum of 2 times.

If the server returns an ENOENT error, we still need to do a d_delete() in order to ensure that the dentry is deleted. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

In nfs_do_call_unlink() we check that we haven't raced, and that lookup() hasn't created an aliased dentry to our sillydeleted dentry.

Ensure that readdir revalidates its data cache after blocking on sillyrename. Also fix a typo in nfs_do_call_unlink(): swap the ^= for an |=. The result is the same, since we've already checked that the flag is unset, but it makes the code more readable. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

The new e1000e driver is apparently not yet suitable for general use, so mark it experimental, and re-instate all the PCI-Express device IDs in the old and stable e1000 driver so that people (namely me) can continue to use a driver that actually works. Auke & co have been appraised of the situation.

A bug report on nfsd that states that since it was switched to use splice instead of sendfile, the atime was no longer being updated on the input file. do_generic_mapping_read() does this when accessing the file, make splice do it for the direct splice handler.
