* SUNRPC: Ensure client closes the socket when server initiates a closeTrond Myklebust2006-01-06
| | | | | | | | | | | | If the server decides to close the RPC socket, we currently don't actually respond until either another RPC call is scheduled, or until xprt_autoclose() gets called by the socket expiry timer (which may be up to 5 minutes later). This patch ensures that xprt_autoclose() is called much sooner if the server closes the socket. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* SUNRPC: get rid of cl_chattyChuck Lever2006-01-06
| | | | | | | | | | | | Clean up: Every ULP that uses the in-kernel RPC client, except the NLM client, sets cl_chatty. There's no reason why NLM shouldn't set it, so just get rid of cl_chatty and always be verbose. Test-plan: Compile with CONFIG_NFS enabled.

* SUNRPC: transport switch API for setting port numberChuck Lever2006-01-06
| | | | | | | | | | | | | | | At some point, transport endpoint addresses will no longer be IPv4. To hide the structure of the rpc_xprt's address field from ULPs and port mappers, add an API for setting the port number during an RPC bind operation. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked. Probably need to rig a server where certain services aren't running, or that returns an error for some typical operation.

* SUNRPC: new interface to force an RPC rebindChuck Lever2006-01-06
| | | | | | | | | | | | | | | We'd like to hide fields in rpc_xprt and rpc_clnt from upper layer protocols. Start by creating an API to force RPC rebind, replacing logic that simply sets cl_port to zero. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP.

* SUNRPC: switchable buffer allocationChuck Lever2006-01-06
| | | | | | | | | | | | | | | | | | | | Add RPC client transport switch support for replacing buffer management on a per-transport basis. In the current IPv4 socket transport implementation, RPC buffers are allocated as needed for each RPC message that is sent. Some transport implementations may choose to use pre-allocated buffers for encoding, sending, receiving, and unmarshalling RPC messages, however. For transports capable of direct data placement, the buffers can be carved out of a pre-registered area of memory rather than from a slab cache. Test-plan: Millions of fsx operations. Performance characterization with "sio" and "iozone". Use oprofile and other tools to look for significant regression in CPU utilization.

* NFSv4: stateful NFSv4 RPC call interfaceTrond Myklebust2006-01-06
| | | | | | | | | | | | | | The NFSv4 model requires us to complete all RPC calls that might establish state on the server whether or not the user wants to interrupt it. We may also need to schedule new work (including new RPC calls) in order to cancel the new state. The asynchronous RPC model will allow us to ensure that RPC calls always complete, but in order to allow for "synchronous" RPC, we want to add the ability to wait for completion. The waits are, of course, interruptible. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* [PATCH] Keep nfsd from exiting when seeing recv() errorsOlaf Kirch2006-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I submitted this one previously - svc_tcp_recvfrom currently returns any errors to the caller, including ECONNRESET and the like. This is something svc_recv isn't able to deal with: len = svsk->sk_recvfrom(rqstp); [...] if (len == 0 || len == -EAGAIN) { [...] return -EAGAIN; } [...] return len; The nfsd main loop will exit when it sees an error code other than EAGAIN. The following patch fixes this problem svc_recv is not equipped to deal with error codes other than EAGAIN, and will propagate anything else (such as ECONNRESET) up to nfsd, causing it to exit.

* [PATCH] knfsd: fix hash function for IP addresses on 64bit little-endian ↵NeilBrown2006-01-06
| | | | | | | | | | | | | | | | | | | | | | | | machines. The hash.h hash_long function, when used on a 64 bit machine, ignores many of the middle-order bits. (The prime chosen it too bit-sparse). IP addresses for clients of an NFS server are very likely to differ only in the low-order bits. As addresses are stored in network-byte-order, these bits become middle-order bits in a little-endian 64bit 'long', and so do not contribute to the hash. Thus you can have the situation where all clients appear on one hash chain. So, until hash_long is fixed (or maybe forever), us a hash function that works well on IP addresses - xor the bytes together. Thanks to "Iozone" <capps@iozone.org> for identifying this problem.

* [NET]: move struct proto_ops to constEric Dumazet2006-01-03
| | | | | | | | | | | | | | | | | | | | | | I noticed that some of 'struct proto_ops' used in the kernel may share a cache line used by locks or other heavily modified data. (default linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at least) This patch makes sure a 'struct proto_ops' can be declared as const, so that all cpus can share all parts of it without false sharing. This is not mandatory : a driver can still use a read/write structure if it needs to (and eventually a __read_mostly) I made a global stubstitute to change all existing occurences to make them const. This should reduce the possibility of false sharing on SMP, and speedup some socket system calls. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

* [PATCH] knfsd: make sure nfsd doesn't hog a cpu foreverNeilBrown2005-11-15
| | | | | | | | | | | | | | | Being kernel-threads, nfsd servers don't get pre-empted (depending on CONFIG). If there is a steady stream of NFS requests that can be served from cache, an nfsd thread may hold on to a cpu indefinitely, which isn't very friendly. So it is good to have a cond_resched in there (just before looking for a new request to serve), to make sure we play nice.

* [PATCH] SUNRPC: don't reencode when looping in call transmit.Trond Myklebust2005-11-09
| | | | | | | | | | | | | | | If the call to xprt_transmit() fails due to socket buffer space exhaustion, we do not need to re-encode the RPC message when we loop back through call_transmit. Re-encoding can actually end up triggering the WARN_ON() in call_decode() if we re-encode something like a read() request and auth->au_rslack has changed. It can also cause us to increment the RPCSEC_GSS sequence number beyond the limits of the allowed window.

* [PATCH] sanitize lookup_hash prototypeChristoph Hellwig2005-11-09
| | | | | | | | | | | | | | | | | | | | | | | ->permission and ->lookup have a struct nameidata * argument these days to pass down lookup intents. Unfortunately some callers of lookup_hash don't actually pass this one down. For lookup_one_len() we don't have a struct nameidata to pass down, but as this function is a library function only used by filesystem code this is an acceptable limitation. All other callers should pass down the nameidata, so this patch changes the lookup_hash interface to only take a struct nameidata argument and derives the other two arguments to __lookup_hash from it. All callers already have the nameidata argument available so this is not a problem. At the same time I'd like to deprecate the lookup_hash interface as there are better exported interfaces for filesystem usage. Before it can actually be removed I need to fix up rpc_pipefs.
