* sunrpc: honor rpc_task's timeout value in rpcb_create()Eryu Guan2021-04-051-2/+5
| | | | | | | | | | | | Currently rpcbind client is created without setting rpc timeout (thus using the default value). But if the rpc_task already has a customized timeout in its tk_client field, it's also ignored. Let's use the same timeout setting in rpc_task->tk_client->cl_timeout for rpcbind connection.

* SUNRPC: Remove unreachable error condition in rpcb_getport_async()Xiyu Yang2020-05-281-6/+0
| | | | | | | | | | | rpcb_getport_async() invokes rpcb_call_async(), which return the value of rpc_run_task() to "child". Since rpc_run_task() is impossible to return an ERR pointer, there is no need to add the IS_ERR() condition on "child" here. So we need to remove it.

* sunrpc: convert unnecessary GFP_ATOMIC to GFP_NOFSJ. Bruce Fields2019-01-021-2/+2
| | | | | | | | | | | | | | | | | | It's OK to sleep here, we just don't want to recurse into the filesystem as a writeout could be waiting on this. Future work: the documentation for GFP_NOFS says "Please try to avoid using this flag directly and instead use memalloc_nofs_{save,restore} to mark the whole scope which cannot/shouldn't recurse into the FS layer with a short explanation why. All allocation requests will inherit GFP_NOFS implicitly." But I'm not sure where to do this. Should the workqueue be arranging that for us in the case of workqueues created with WQ_MEM_RECLAIM?

* SUNRPC: If the rpcbind channel is disconnected, fail the call to unregisterTrond Myklebust2013-08-071-13/+27
| | | | | | | | | | | | | | | | If rpcbind causes our connection to the AF_LOCAL socket to close after we've registered a service, then we want to be careful about reconnecting since the mount namespace may have changed. By simply refusing to reconnect the AF_LOCAL socket in the case of unregister, we avoid the need to somehow save the mount namespace. While this may lead to some services not unregistering properly, it should be safe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new routine is responsible for service registration in a specified network context.
