Fill in missing pieces in the kernel RPC server's UDP receive path to request IPv6 PKTINFO and correctly parse the IPv6 cmsg header. Without this patch, kernel RPC services drop all incoming requests on UDP on IPv6. Related commit: 7a37f5787e76bf1765c1add3a9a7163f841a28bb Signed-off-by: Chuck Lever Cc: Neil Brown Signed-off-by: J.

While deferred requests normally get revisited quite quickly, it is possible for a request to remain in the deferral queue when the cache item is discarded. We can easily make sure that doesn't happen by calling cache_revisit_request just before the final 'put'. Also there is a small chance that a race would cause one thread to defer a request against a cache item while another thread is failing to queue an upcall for that item. So when the upcall fails, make sure to revisit all deferred requests. Signed-off-by: NeilBrown Signed-off-by: J.

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.

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 4013edea9a0b6cdcb1fdf5d4011e47e068fd6efb If 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'.

The amount of what actually is usable as storage should instead be used as a basis here. Some of the calculations (i.e. those not intending to use high memory) should likely even use (totalram_pages - totalhigh_pages).

[[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 c I 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.
