svc_xprt_received must be called when ->xpo_recvfrom has finished
receiving a message, so that the XPT_BUSY flag will be cleared and
if necessary, requeued for further work.
This call is currently made in each ->xpo_recvfrom function, often
from multiple different points. In each case it is the earliest point
on a particular path where it is known that the protection provided by
XPT_BUSY is no longer needed.
However there are (still) some error paths which do not call
svc_xprt_received, and requiring each ->xpo_recvfrom to make the call
does not encourage robustness.
So: move the svc_xprt_received call to be made just after the
call to ->xpo_recvfrom(), and move it of the various ->xpo_recvfrom
methods.
This means that it may not be called at the earliest possible instant,
but this is unlikely to be a measurable performance issue.
Note that there are still other calls to svc_xprt_received as it is
also needed when an xprt is newly created.

One the changes in commit d7979ae4a "svc: Move close processing to a
single place" is:
err_delete:
- svc_delete_socket(svsk);
+ set_bit(SK_CLOSE, &svsk->sk_flags);
return -EAGAIN;
This is insufficient. The recvfrom methods must always call
svc_xprt_received on completion so that the socket gets re-queued if
there is any more work to do. This particular path did not make that
call because it actually destroyed the svsk, making requeue pointless.
When the svc_delete_socket was change to just set a bit, we should have
added a call to svc_xprt_received,
This is the problem that b0401d7253 attempted to fix, incorrectly.

Goal is to transfert fields used at lookup time in the first
read-mostly cache line (inside struct sock_common) and move sk_refcnt
to a separate cache line (only written by rx path)
This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr,

Currently, the sunrpc server is refusing to allow us to process new RPC
calls if the TCP send buffer is 2/3 full, even if we do actually have
enough free space to guarantee that we can send another request.
The following patch fixes svc_tcp_has_wspace() so that we only stop
processing requests if we know that the socket buffer cannot possibly fit
another reply.
It also fixes the tcp write_space() callback so that we only clear the
SOCK_NOSPACE flag when the TCP send buffer is less than 2/3 full.
This should ensure that the send window will grow as per the standard TCP
socket code.

The svc_addr_len() helper function returns -EAFNOSUPPORT if it doesn't
recognize the address family of the passed-in socket address. However,
the return type of this function is size_t, which means -EAFNOSUPPORT
is turned into a very large positive value in this case.
The check in svc_udp_recvfrom() to see if the return value is less
than zero therefore won't work at all.
Additionally, handle_connect_req() passes this value directly to
memset(). This could cause memset() to clobber a large chunk of memory
if svc_addr_len() has returned an error. Currently the address family
of these addresses, however, is known to be supported long before
handle_connect_req() is called, so this isn't a real risk.
Change the error return value of svc_addr_len() to zero, which fits in
the range of size_t, and is safer to pass to memset() directly.

The sv_family field is going away. Instead of using sv_family, have
the svc_register() function take a protocol family argument.
Since this argument represents a protocol family, and not an address
family, this argument takes an int, as this is what is passed to
sock_create_kern(). Also make sure svc_register's helpers are
checking for PF_FOO instead of AF_FOO. The value of [AP]F_FOO are
equivalent; this is simply a symbolic change to reflect the semantics
of the value stored in that variable.
sock_create_kern() should return EPFNOSUPPORT if the passed-in
protocol family isn't supported, but it uses EAFNOSUPPORT for this
case. We will stick with that tradition here, as svc_register()
is called by the RPC server in the same path as sock_create_kern().

Allow the NFSv4 server to make use of TCP autotuning behaviour, which
was previously disabled by setting the sk_userlocks variable.
Set the receive buffers to be big enough to receive the whole RPC
request, and set this for the listening socket, not the accept socket.
Remove the code that readjusts the receive/send buffer sizes for the
accepted socket. Previously this code was used to influence the TCP
window management behaviour, which is no longer needed when autotuning
is enabled.
This can improve IO bandwidth on networks with high bandwidth-delay
products, where a large tcp window is required. It also simplifies
performance tuning, since getting adequate tcp buffers previously
required increasing the number of nfsd threads.

My plan is to use an AF_INET listener on systems that support only IPv4,

Max Matveev <makc@sgi.com> says:
Creating a single listener can be dangerous - if net.ipv6.bindv6only
is enabled then it's possible to create another listener in v4
namespace on the same port and steal the traffic from the "unifed"
listener. You need to disable V6ONLY explicitly via a sockopt to stop
that.
