This gets Samba to now correctly return STATUS_PATH_NOT_COVERED when it is supposed to (Windows already did since the direction of the slash was not an issue for them).

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.

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.

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.

One was > that one of the tests in the locking tests was racy when it didn't seem > to need to be and two, that the NFS client asynchronously releases locks > when a process is exiting. ... > The Single UNIX Specification Version 3 specifies that: "All locks > associated with a file for a given process shall be removed when a file > descriptor for that file is closed by that process or the process holding > that file descriptor terminates.". > > This does not specify whether those locks must be released prior to the > completion of the exit processing for the process or not. However, > general assumptions seem to be that those locks will be released. This > leads to more deterministic behavior under normal circumstances. The following patch converts the NFSv2/v3 locking code to use the same mechanism as NFSv4 for sending asynchronous RPC calls and then waiting for them to complete. This ensures that the UNLOCK and CANCEL RPC calls will complete even if the user interrupts the call, yet satisfies the above request for synchronous behaviour on process exit.

| | * | | | | SUNRPC: Fix read ordering problems with req->rq_private_buf.lenTrond Myklebust2008-04-192-14/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().
