NLM: Remove unused argument from svc_addsock() function

2008-10-04T21:12:27+00:00

Clean up: The svc_addsock() function no longer uses its "proto"
argument, so remove it.

SUNRPC: Update RPC server's TCP record marker decoder

Clean up: Update the RPC server's TCP record marker decoder to match the
constructs used by the RPC client's TCP socket transport.

svc: Move the sockaddr information to svc_xprt

2008-02-01T21:42:12+00:00

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: Make deferral processing xprt independent

2008-02-01T21:42:12+00:00

This patch moves the transport independent sk_deferred list to the svc_xprt
structure and updates the svc_deferred_req structure to keep pointers to
svc_xprt's directly. The deferral processing code is also moved out of the
transport dependent recvfrom functions and into the generic svc_recv path.

svc: Move the authinfo cache to svc_xprt.

2008-02-01T21:42:12+00:00

Move the authinfo cache to svc_xprt. This allows both the TCP and RDMA
transports to share this logic. A flag bit is used to determine if
auth information is to be cached or not. Previously, this code looked
at the transport protocol.

I've also changed the spin_lock/unlock logic so that a lock is not taken for
transports that are not caching auth info.

svc: Remove sk_lastrecv

2008-02-01T21:42:12+00:00

With the implementation of the new mark and sweep algorithm for shutting
down old connections, the sk_lastrecv field is no longer needed.

svc: Make svc_send transport neutral

2008-02-01T21:42:11+00:00

Move the sk_mutex field to the transport independent svc_xprt structure.
Now all the fields that svc_send touches are transport neutral. Change the
svc_send function to use the transport independent svc_xprt directly instead
of the transport dependent svc_sock structure.

svc: Make close transport independent

2008-02-01T21:42:11+00:00

Move sk_list and sk_ready to svc_xprt. This involves close because these
lists are walked by svcs when closing all their transports. So I combined
the moving of these lists to svc_xprt with making close transport independent.

The svc_force_sock_close has been changed to svc_close_all and takes a list
as an argument. This removes some svc internals knowledge from the svcs.

This code races with module removal and transport addition.

Thanks to Simon Holm Thøgersen for a compile fix.

svc: Move sk_server and sk_pool to svc_xprt

This is another incremental change that moves transport independent
fields from svc_sock to the svc_xprt structure. The changes
should be functionally null.
