* | SUNRPC: Add support for per-client timeout valuesTrond Myklebust2008-01-30
| | | | | | | | | | | | | | | | In order to be able to support setting the timeo and retrans parameters on a per-mountpoint basis, we move the rpc_timeout structure into the rpc_clnt. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* | SUNRPC: cleanup for rpc_new_client()Trond Myklebust2008-01-30
| | | | | | | | | | | | There is no reason why we shouldn't just pass the rpc_create_args. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* | SUNRPC: Move universal address definitions to global headerChuck Lever2008-01-30
| | | | | | | | | | | | | | | | | | | | Universal addresses are defined in RFC 1833 and clarified in RFC 3530. We need to use them in several places in the NFS and RPC clients, so move the relevant definition and block comment to an appropriate global include file.

* | SUNRPC: rpc_create() default hostname should support AF_INET6 addressesChuck Lever2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | If the ULP doesn't pass a hostname string to rpc_create(), it manufactures one based on the passed-in address. Be smart enough to handle an AF_INET6 address properly in this case. Move the default servername logic before the xprt_create_transport() call to simplify error handling in rpc_create().

* | SUNRPC: Remove an unneeded implicit type cast when calling rpc_depopulate()Chuck Lever2008-01-30
| | | | | | | | | | | | | | | | The two arguments of rpc_depopulate() that pass in inode numbers should use the same type as inode->i_ino: unsigned long. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* | SUNRPC: temp var should match return type of xdr_skb_read_actorChuck Lever2008-01-30
| | | | | | | | | | | | | | | | The return type of xdr_skb_read_actor functions is size_t. This fixes a nit I unwittingly overlooked in commit dd456471. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* | SUNRPC: Fix an unnecessary implicit type cast in rpcrdma_count_chunks()Chuck Lever2008-01-30
| | | | | | | | | | | | | | | | | | | | Nit: rl_nchunks is an unsigned integer, so pass it into rpcrdma_count_chunks() via an unsigned integer argument. This eliminates a harmless mixed sign comparison in rpcrdma_count_chunks() Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Cc: Thomas Talpey <Thomas.Talpey@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | We want the default scheduling priority (priority == 0) to remain RPC_PRIORITY_NORMAL.

* | SUNRPC: Restrict sunrpc client exportsTrond Myklebust2008-01-30
| | | | | | | | | | | | | | | | The sunrpc client exports are not meant to be part of any official kernel API: they can change at the drop of a hat. Mark them as internal functions using EXPORT_SYMBOL_GPL. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* | SUNRPC: Reconnect immediately whenever the server isn't refusing it.Trond Myklebust2008-01-30
| | | | | | | | | | | | | | 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>
* | SUNRPC: Rename xprt_disconnect()Trond Myklebust2008-01-30
| | | | | | | | | | | | | | | | 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>
* | SUNRPC: Make call_status()/call_decode() call xprt_force_disconnect()Trond Myklebust2008-01-30
| | | | | | | | | | | | | | | | | | 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>
* | SUNRPC: xprt_autoclose() should not call xprt_disconnect()Trond Myklebust2008-01-30
| | | | | | | | | | | | | | | | | | | | | | 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>
* | SUNRPC: Use shutdown() instead of close() when disconnecting a TCP socketTrond Myklebust2008-01-30
| | | | | | | | | | | | | | | | | | | | 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.

* | SUNRPC: Allow the client to detect if the TCP connection is closedTrond Myklebust2008-01-30
| | | | | | | | | | | | | | | | 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>
* | SUNRPC: Fix TCP rebinding logicTrond Myklebust2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | SUNRPC: Fix a race in xs_tcp_state_change()Trond Myklebust2008-01-30
| | | | | | | | | | | | | | When scheduling the autoclose RPC call, we want to ensure that we don't race against the test_bit() call in xprt_clear_locked(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | The previous move of the the UDP inDatagrams counter caused the counting of encapsulated packets, SUNRPC data (as opposed to call) packets and RXRPC packets to go missing.

* | SUNRPC xprtrdma: fix XDR tail buf marshalling for all opsJames Lentini2007-12-11
|/ | | | | | | | | | | | | | | | | | rpcrdma_convert_iovs is passed an xdr_buf representing either an RPC request or an RPC reply. In the case of a request, several calculations and tests involving pos are unnecessary. In the case of a reply, several calculations and tests involving pos are incorrect (the code tests pos against the reply xdr buf's len field, which is always 0 at the time rpcrdma_convert_iovs is executed). This change removes the incorrect/unnecessary calculations and tests involving pos. This fixes an observed problem when reading certain file sizes over NFS/RDMA.
