| | * SUNRPC: Invalidate the RPCSEC_GSS session if the server dropped the requestTrond Myklebust2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RFC 2203 requires the server to drop the request if it believes the RPCSEC_GSS context is out of sequence. The problem is that we have no way on the client to know why the server dropped the request. In order to avoid spinning forever trying to resend the request, the safe approach is therefore to always invalidate the RPCSEC_GSS context on every major timeout.

| | * SUNRPC: Don't change the RPCSEC_GSS context on a credential that is in useTrond Myklebust2008-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a server rejects our credential with an AUTH_REJECTEDCRED or similar, we need to refresh the credential and then retry the request. However, we do want to allow any requests that are in flight to finish executing, so that we can at least attempt to process the replies that depend on this instance of the credential. The solution is to ensure that gss_refresh() looks up an entirely new RPCSEC_GSS credential instead of attempting to create a context for the existing invalid credential.

| | * SUNRPC: Don't disconnect more than once if retransmitting NFSv4 requestsTrond Myklebust2008-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NFSv4 requires us to ensure that we break the TCP connection before we're allowed to retransmit a request. However in the case where we're retransmitting several requests that have been sent on the same connection, we need to ensure that we don't interfere with the attempt to reconnect and/or break the connection again once it has been established. We therefore introduce a 'connection' cookie that is bumped every time a connection is broken. This allows requests to track if they need to force a disconnection.

| | | | | | | | | | | | | | | | | | | | | | | | | | | We need to try to ensure that we always use the same credentials whenever we re-establish the clientid on the server. If not, the server won't recognise that we're the same client, and so may not allow us to recover state. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | * SUNRPC: Fix read ordering problems with req->rq_private_buf.lenTrond Myklebust2008-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to ensure that req->rq_private_buf.len is updated before req->rq_received, so that call_decode() doesn't use an old value for req->rq_rcv_buf.len. In 'call_decode()' itself, instead of using task->tk_status (which is set using req->rq_received) must use the actual value of req->rq_private_buf.len when deciding whether or not the received RPC reply is too short. Finally ensure that we set req->rq_rcv_buf.len to zero when retrying a request. A typo meant that we were resetting req->rq_private_buf.len in call_decode(), and then clobbering that value with the old rq_rcv_buf.len again in xprt_transmit().

| | * SUNRPC: Don't attempt to destroy expired RPCSEC_GSS credentials..Trond Myklebust2008-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ..and always destroy using a 'soft' RPC call. Destroying GSS credentials isn't mandatory; the server can always cope with a few credentials not getting destroyed in a timely fashion. This actually fixes a hang situation. Basically, some servers will decide that the client is crazy if it tries to destroy an RPC context for which they have sent an RPCSEC_GSS_CREDPROBLEM, and so will refuse to talk to it for a while. The regression therefor probably was introduced by commit 0df7fb74fbb709591301871a38aac7735a1d6583. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rest of the networking layer uses SOCK_ASYNC_NOSPACE to signal whether or not we have someone waiting for buffer memory. Convert the SUNRPC layer to use the same idiom. Remove the unlikely()s in xs_udp_write_space and xs_tcp_write_space. In fact, the most common case will be that there is nobody waiting for buffer space. SOCK_NOSPACE is there to tell the TCP layer whether or not the cwnd was limited by the application window. Ensure that we follow the same idiom as the rest of the networking layer here too. Finally, ensure that we clear SOCK_ASYNC_NOSPACE once we wake up, so that write_space() doesn't keep waking things up on xprt->pending. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

Instead of having the NFS client code cache credentials that are tied to a particular AUTH method it is therefore preferable to have a generic credential that can be converted into whatever AUTH is in use by the RPC client when the read/write/sillyrename/... is put on the wire. We do this by means of the new "generic" credential, which basically just caches the minimal information that is needed to look up an RPCSEC_GSS, AUTH_SYS, or AUTH_NULL credential.

As long as the softirq is able to signal that the wakeup is due to a timeout (which it can do by setting task->tk_status to -ETIMEDOUT) then the callback functions can just run as standard task->tk_callback functions (in the rpciod/process context). The only possible border-line case would be xprt_timer() for the case of UDP, when the callback is used to reduce the size of the transport congestion window. In testing, however, the effect of moving that update to a callback would appear to be minor. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
