* [PATCH] knfsd: SUNRPC: Provide room in svc_rqst for larger addressesChuck Lever2007-02-123-5/+9
| | | | | | | | | | | | | | Expand the rq_addr field to allow it to contain larger addresses. Specifically, we replace a 'sockaddr_in' with a 'sockaddr_storage', then everywhere the 'sockaddr_in' was referenced, we use instead an accessor function (svc_addr_in) which safely casts the _storage to _in.

| | | | | | | | | | | | | | | | | for printing There are loads of places where the RPC server assumes that the rq_addr fields contains an IPv4 address. Top among these are error and debugging messages that display the server's IP address. Let's refactor the address printing into a separate function that's smart enough to figure out the difference between IPv4 and IPv6 addresses.

* [PATCH] knfsd: Allow lockd to drop replies as appropriateNeilBrown2006-10-173-19/+15
| | | | | | | | | | | | | | | | | | | | | It is possible for the ->fopen callback from lockd into nfsd to find that an answer cannot be given straight away (an upcall is needed) and so the request has to be 'dropped', to be retried later. That error status is not currently propagated back. So: Change nlm_fopen to return nlm error codes (rather than a private protocol) and define a new nlm_drop_reply code. Cause nlm_drop_reply to cause the rpc request to get rpc_drop_reply when this error comes back. Cause svc_process to drop a request which returns a status of rpc_drop_reply.

* [PATCH] knfsd: Fix bug in recent lockd patches that can cause reclaim to failNeilBrown2006-10-171-1/+10
| | | | | | | | | | | | | | | | | | | | When an nfs server shuts down, lockd needs to release all the locks even though the client still holds them. It should therefore not 'unmonitor' the clients, so that the files in nfs/sm will still be there when the nfs server restarts, so that those clients will be told to reclaim their locks. However the hosts are fully unmonitored, so statd may well remove the files. lockd has a test for 'sm_sticky' and avoid the unmonitor call if it is set, but it is currently not set. So set it when tearing down lockd. Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | Every NLM call includes the client's NSM state. Currently, the Linux client always reports 0 - which seems not to cause any problems, but is not what the protocol says.

* [PATCH] knfsd: match GRANTED_RES replies using cookiesOlaf Kirch2006-10-043-13/+15
| | | | | | | | | | | | | | | | | | When we send a GRANTED_MSG call, we current copy the NLM cookie provided in the original LOCK call - because in 1996, some broken clients seemed to rely on this bug. However, this means the cookies are not unique, so that when the client's GRANTED_RES message comes back, we cannot simply match it based on the cookie, but have to use the client's IP address in addition. Which breaks when you have a multi-homed NFS client. The X/Open spec explicitly mentions that clients should not expect the same cookie; so one may hope that any clients that were broken in 1996 have either been fixed or rendered obsolete.

| | | | | | | | | | | | | | | | As a result of previous patches, the loop in nlmsvc_invalidate_all just sets h_expires for all client/hosts to 0 (though does it in a very complicated way). This was possibly meant to trigger early garbage collection but half the time '0' is in the future and so it infact delays garbage collection. Pre-aging the 'hosts' is not really needed at this point anyway so we throw out the loop and nlm_find_client which is no longer needed.

Then some of that functionality is moved out into nlm_host_rebooted (which calls nlmclnt_recovery which starts a thread which runs reclaimer).

* [PATCH] knfsd: be more selective in which sockets lockd listens onNeilBrown2006-10-022-8/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently lockd listens on UDP always, and TCP if CONFIG_NFSD_TCP is set. However as lockd performs services of the client as well, this is a problem. If CONFIG_NfSD_TCP is not set, and a tcp mount is used, the server will not be able to call back to lockd. So: - add an option to lockd_up saying which protocol is needed - Always open sockets for which an explicit port was given, otherwise only open a socket of the type required - Change nfsd to do one lockd_up per socket rather than one per thread. This - removes the dependancy on CONFIG_NFSD_TCP - means that lockd may open sockets other than at startup - means that lockd will *not* listen on UDP if the only mounts are TCP mount (and nfsd hasn't started). The latter is the only one that concerns me at all - I don't know if this might be a problem with some servers.

* [PATCH] knfsd: add a callback for when last rpc thread finishesNeilBrown2006-10-021-1/+1
| | | | | | | | | | | | nfsd has some cleanup that it wants to do when the last thread exits, and there will shortly be some more. So collect this all into one place and define a callback for an rpc service to call when the service is about to be destroyed.

* LOCKD: Convert to use new rpc_create() APIChuck Lever2006-09-222-47/+44
| | | | | | | | | | | | | | | Replace xprt_create_proto/rpc_create_client with new rpc_create() interface in the Network Lock Manager. Note that the semantics of NLM transports is now "hard" instead of "soft" to provide a better guarantee that lock requests will get to the server. Test plan: Repeated runs of Connectathon locking suite. Check network trace to ensure NLM requests are working correctly.
