Remove include of two headers never used by this file.
Doing so exposed a missing #include in
include/linux/sunrpc/rpc_rdma.h.I did not see any other users dependency but if exist they
should be fixed since these headers are totally irrelevant

The kernel sometimes makes RPC calls to services that aren't running.
Because the kernel's RPC client always assumes the hard retry semantic
when reconnecting a connection-oriented RPC transport, the underlying
reconnect logic takes a long while to time out, even though the remote
may have responded immediately with ECONNREFUSED.In certain cases, like upcalls to our local rpcbind daemon, or for NFS
mount requests, we'd like the kernel to fail immediately if the remote
service isn't reachable. This allows another transport to be tried
immediately, or the pending request can be abandoned quickly.Introduce a per-request flag which controls how call_transmit_status()
behaves when request transmission fails because the server cannot be
reached.We don't want soft connection semantics to apply to other errors. The
default case of the switch statement in call_transmit_status() no
longer falls through; the fall through code is copied to the default
case, and a "break;" is added.The transport's connection re-establishment timeout is also ignored for
such requests. We want the request to fail immediately, so the
reconnect delay is skipped. Additionally, we don't want a connect
failure here to further increase the reconnect timeout value, since
this request will not be retried.Signed-off-by: Chuck Lever

When a SETCLIENTID call comes in, one of the args given is the svc_rqst.
This struct contains an rq_addr field which holds the address that sent
the call. If this is an IPv6 address, then we can use the sin6_scope_id
field in this address to populate the sin6_scope_id field in the
callback address.AFAICT, the rq_addr.sin6_scope_id is non-zero if and only if the client
mounted the server's link-local address.Signed-off-by: Jeff Layton

For events that are rare, such as referral DNS lookups, it makes limited
sense to have a daemon constantly listening for upcalls on a channel. An
alternative in those cases might simply be to run the app that fills the
cache using call_usermodehelper_exec() and friends.The following patch allows the cache_detail to specify alternative upcall
mechanisms for these particular cases.Signed-off-by: Trond Myklebust

There is still a little wart or two there: Since we've already got a
vfsmount, we might as well pass that in to rpc_create_client_dir.
Another point is that if we open code __rpc_lookup_path() here, then we can
avoid looking up the entire parent directory path over and over again: it
doesn't change.Also get rid of rpc_clnt->cl_pathname, since it has no users...

RPC universal address generation is currently done in several places:
rpcb_clnt.c, nfs4proc.c xprtsock.c, and xprtrdma.c. Remove the
redundant cases that convert a socket address to a universal
address. The nfs4proc.c case takes a pre-formatted presentation
address string, not a socket address, so we'll leave that one.Because the new uaddr constructor uses the recently introduced
rpc_ntop(), it now supports proper "::" shorthanding for IPv6
addresses. This allows the kernel to register properly formed
universal addresses with the local rpcbind service, in _all_ cases.The kernel can now also send properly formed universal addresses in
RPCB_GETADDR requests, and support link-local properly when
encoding and decoding IPv6 addresses.Signed-off-by: Chuck Lever
Signed-off-by: Trond Myklebust -
Introduce a set of functions in the kernel's RPC implementation for
converting between a socket address and either a standard
presentation address string or an RPC universal address.The universal address functions will be used to encode and decode
RPCB_FOO and NFSv4 SETCLIENTID arguments. The other functions are
part of a previous promise to deliver shared functions that can be
used by upper-layer protocols to display and manipulate IP
addresses.The kernel's current address printf formatters were designed
specifically for kernel to user-space APIs that require a particular
string format for socket addresses, thus are somewhat limited for the
purposes of sunrpc.ko. The formatter for IPv6 addresses, %pI6, does
not support short-handing or scope IDs. Also, these printf formatters
are unique per address family, so a separate formatter string is
required for printing AF_INET and AF_INET6 addresses.Signed-off-by: Chuck Lever

For nfs41 callbacks we need an svc_xprt to process requests coming up the
backchannel socket as rpc_rqst's that are transformed into svc_rqst's that
need a rq_xprt to be processed.The svc_{udp,tcp}_create methods are too heavy for this job as svc_create_socket
creates an actual socket to listen on while for nfs41 we're "reusing" the
fore channel's socket.Signed-off-by: Benny Halevy
