| * SUNRPC: Add an rpc_credop callback for binding a credential to an rpc_taskTrond Myklebust2008-03-14
| | | | | | | | | | | | | | We need the ability to treat 'generic' creds specially, since they want to bind instances of the auth cred instead of binding themselves. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| * | SUNRPC: Run rpc timeout functions as callbacks instead of in softirqsTrond Myklebust2008-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An audit of the current RPC timeout functions shows that they don't really ever need to run in the softirq context. 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>

* svc: Move the sockaddr information to svc_xprtTom Tucker2008-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the transport sockaddr to the svc_xprt structure. Convenience functions are added to set and get the local and remote addresses of a transport from the transport provider as well as determine the length of a sockaddr. A transport is responsible for setting the xpt_local and xpt_remote addresses in the svc_xprt structure as part of transport creation and xpo_accept processing. This cannot be done in a generic way and in fact varies between TCP, UDP and RDMA. A set of xpo_ functions (e.g. getlocalname, getremotename) could have been added but this would have resulted in additional caching and copying of the addresses around. Note that the xpt_local address should also be set on listening endpoints; for TCP/RDMA this is done as part of endpoint creation. For connected transports like TCP and RDMA, the addresses never change and can be set once and copied into the rqstp structure for each request. For UDP, however, the local and remote addresses may change for each request. In this case, the address information is obtained from the UDP recvmsg info and copied into the rqstp structure from there. A svc_xprt_local_port function was also added that returns the local port given a transport. This is used by svc_create_xprt when returning the port associated with a newly created transport, and later when creating a generic find transport service to check if a service is already listening on a given port.

* svc: Add xpo_accept transport functionTom Tucker2008-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the accept logic looked into the socket state to determine whether to call accept or recv when data-ready was indicated on an endpoint. Since some transports don't use sockets, this logic now uses a flag bit (SK_LISTENER) to identify listening endpoints. A transport function (xpo_accept) allows each transport to define its own accept processing. A transport's initialization logic is reponsible for setting the SK_LISTENER bit. I didn't see any way to do this in transport independent logic since the passive side of a UDP connection doesn't listen and always recv's. In the svc_recv function, if the SK_LISTENER bit is set, the transport xpo_accept function is called to handle accept processing. Note that all functions are defined even if they don't make sense for a given transport. For example, accept doesn't mean anything for UDP. The function is defined anyway and bug checks if called. The UDP transport should never set the SK_LISTENER bit.
