The size of buf[] must account for the string termination needed for
the first strict_strtoul() call. Introduced in commit a02d6926.Fábio Olivé Leite points out that strict_strtoul() requires _either_
'\n\0' _or_ '\0' termination, so use the simpler '\0' here instead.See http://bugzilla.kernel.org/show_bug.cgi?id=14546 .

In order to have better cache layouts of struct sock (separate zones
for rx/tx paths), we need this preliminary patch.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,
sport and id fields. This allows a future patch to define these
fields as macros, like sk_refcnt, without name clashes.Signed-off-by: Eric Dumazet

[[resending with correct cc: - "vfs.kernel.org" just isn't right!]]
xprt->reestablish_timeout is used to cause TCP connection attempts to
back off if the connection fails so as not to hammer the network,
but to still allow immediate connections when there is no reason to
believe there is a problem.It is not used for the first connection (when transport->sock is NULL)
but only on reconnects.It is currently set:
a/ to 0 when xs_tcp_state_change finds a state of TCP_FIN_WAIT1
on the assumption that the client has closed the connection
so the reconnect should be immediate when needed.
b/ to at least XS_TCP_INIT_REEST_TO when xs_tcp_state_change
detects TCP_CLOSING or TCP_CLOSE_WAIT on the assumption that the
server closed the connection so a small delay at least is
required.
c/ as above when xs_tcp_state_change detects TCP_SYN_SENT, so that
it is never 0 while a connection has been attempted, else
the doubling will produce 0 and there will be no backoff.
d/ to double is value (up to a limit) when delaying a connection,
thus providing exponential backoff and
e/ to XS_TCP_INIT_REEST_TO in xs_setup_tcp as simple initialisation.So you can see it is highly dependant on xs_tcp_state_change being
called as expected. However experimental evidence shows that
xs_tcp_state_change does not see all state changes.
("rpcdebug -m rpc trans" can help show what actually happens).Results show:
TCP_ESTABLISHED is reported when a connection is made. TCP_SYN_SENT
is never reported, so rule 'c' above is never effective.When the server closes the connection, TCP_CLOSE_WAIT and
TCP_LAST_ACK *might* be reported, and TCP_CLOSE is always
reported. This rule 'b' above will sometimes be effective, but
not reliably.When the client closes the connection, it used to result in
TCP_FIN_WAIT1, TCP_FIN_WAIT2, TCP_CLOSE. However since commit
f75e674 (SUNRPC: Fix the problem of EADDRNOTAVAIL syslog floods on
reconnect) we don't see *any* events on client-close. I think this
is because xs_restore_old_callbacks is called to disconnect
xs_tcp_state_change before the socket is closed.
In any case, rule 'a' no longer applies.So all that is left are rule d, which successfully doubles the
timeout which is never rest, and rule e which initialises the timeout.Even if the rules worked as expected, there would be a problem because
a successful connection does not reset the timeout, so a sequence
of events where the server closes the connection (e.g. during failover
testing) will cause longer and longer timeouts with no good reason.This patch:
- sets reestablish_timeout to 0 in xs_close thus effecting rule 'a'
- sets it to 0 in xs_tcp_data_ready to ensure that a successful
connection resets the timeout
- sets it to at least XS_TCP_INIT_REEST_TO after it is doubled,
thus effecting rule cI have not reimplemented rule b and the new version of rule c
seems sufficient.I suspect other code in xs_tcp_data_ready needs to be revised as well.
For example I don't think connect_cookie is being incremented as often
as it should be.Signed-off-by: NeilBrown

In cache_defer_req, 'dreq' is used for two significantly different
values that happen to be of the same type.This is both confusing, and makes it hard to extend the range of one of

The extra call to cache_revisit_request in cache_fresh_unlocked is not
needed, as should have been fairly clear at the time of
commit 4013edea9a0b6cdcb1fdf5d4011e47e068fd6efbIf there are requests to be revisited, then we can be sure that
CACHE_PENDING is set, so the second call is sufficient.So remove the first call.
Then remove the 'new' parameter,
then remove the return value for cache_fresh_locked which is only used
to provide the value for 'new'.Signed-off-by: NeilBrown

As "cache_defer_req" does not sound like a predicate, having it return
a boolean value can be confusing. It is more consistent to return
0 for success and negative for error.Exactly what error code to return is not important as we don't
differentiate between reasons why the request wasn't deferred,
we only care about whether it was deferred or not.Signed-off-by: NeilBrown
