* RPC: add wrapper for svc_reserve to account for checksumJeff Layton2007-05-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the kernel calls svc_reserve to downsize the expected size of an RPC reply, it fails to account for the possibility of a checksum at the end of the packet. If a client mounts a NFSv2/3 with sec=krb5i/p, and does I/O then you'll generally see messages similar to this in the server's ring buffer: RPC request reserved 164 but used 208 While I was never able to verify it, I suspect that this problem is also the root cause of some oopses I've seen under these conditions: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=227726 This is probably also a problem for other sec= types and for NFSv4. The large reserved size for NFSv4 compound packets seems to generally paper over the problem, however. This patch adds a wrapper for svc_reserve that accounts for the possibility of a checksum. It also fixes up the appropriate callers of svc_reserve to call the wrapper. For now, it just uses a hardcoded value that I determined via testing. That value may need to be revised upward as things change, or we may want to eventually add a new auth_op that attempts to calculate this somehow. Unfortunately, there doesn't seem to be a good way to reliably determine the expected checksum length prior to actually calculating it, particularly with schemes like spkm3.

* [PATCH] knfsd: provide sunrpc pool_mode module optionGreg Banks2007-03-061-19/+114
| | | | | | | | | | | | | | | | | | | | | | Provide a module param "pool_mode" for sunrpc.ko which allows a sysadmin to choose the mode for mapping NFS thread service pools to CPUs. Values are: auto choose a mapping mode heuristically global (default, same as the pre-2.6.19 code) a single global pool percpu one pool per CPU pernode one pool per NUMA node Note that since 2.6.19 the hardcoded behaviour has been "auto", this patch makes the default "global". The pool mode can be changed after boot/modprobe using /sys, if the NFS and lockd services have been shut down. A useful side effect of this change is to fix a small memory leak when unloading the module.

* [PATCH] knfsd: fix recently introduced problem with shutting down a busy NFS ↵NeilBrown2007-03-061-12/+9
| | | | | | | | | | | | | | | | | | | | | server When the last thread of nfsd exits, it shuts down all related sockets. It currently uses svc_close_socket to do this, but that only is immediately effective if the socket is not SK_BUSY. If the socket is busy - i.e. if a request has arrived that has not yet been processes - svc_close_socket is not effective and the shutdown process spins. So create a new svc_force_close_socket which removes the SK_BUSY flag is set and then calls svc_close_socket. Also change some open-codes loops in svc_destroy to use list_for_each_entry_safe.

* [PATCH] Convert highest_possible_processor_id to nr_cpu_idsChristoph Lameter2007-02-201-1/+1
| | | | | | | | | | | | | | | | | We frequently need the maximum number of possible processors in order to allocate arrays for all processors. So far this was done using highest_possible_processor_id(). However, we do need the number of processors not the highest id. Moreover the number was so far dynamically calculated on each invokation. The number of possible processors does not change when the system is running. We can therefore calculate that number once.

* [PATCH] Replace highest_possible_node_id() with nr_node_idsChristoph Lameter2007-02-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | highest_possible_node_id() is currently used to calculate the last possible node idso that the network subsystem can figure out how to size per node arrays. I think having the ability to determine the maximum amount of nodes in a system at runtime is useful but then we should name this entry correspondingly, it should return the number of node_ids, and the the value needs to be setup only once on bootup. The node_possible_map does not change after bootup. This patch introduces nr_node_ids and replaces the use of highest_possible_node_id(). nr_node_ids is calculated on bootup when the page allocators pagesets are initialized.

This was the wrong thing to do. I should have just set SK_CLOSE and let normal mechanisms do the work. Not only wrong, but buggy. The locking is all wrong and it openned up a race where-by a socket could be closed twice. So this patch: Introduces svc_close_socket which sets SK_CLOSE then either leave the close up to a thread, or calls svc_delete_socket if it can get SK_BUSY. Adds a bias to sk_busy which is removed when SK_DEAD is set, This avoid races around shutting down the socket. Changes several 'spin_lock' to 'spin_lock_bh' where the _bh was missing.

| | | | | | | | | | | | | | | | | | | | | 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: tidy up up meaning of 'buffer size' in nfsd/sunrpcNeilBrown2006-10-061-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | There is some confusion about the meaning of 'bufsz' for a sunrpc server. In some cases it is the largest message that can be sent or received. In other cases it is the largest 'payload' that can be included in a NFS message. In either case, it is not possible for both the request and the reply to be this large. One of the request or reply may only be one page long, which fits nicely with NFS. So we remove 'bufsz' and replace it with two numbers: 'max_payload' and 'max_mesg'. Max_payload is the size that the server requests. It is used by the server to check the max size allowed on a particular connection: depending on the protocol a lower limit might be used. max_mesg is the largest single message that can be sent or received. It is calculated as the max_payload, rounded up to a multiple of PAGE_SIZE, and with PAGE_SIZE added to overhead. Only one of the request and reply may be this size. The other must be at most one page. Cc: Greg Banks <gnb@sgi.com> Cc: "J.

The code here contributes to the confusion by using "accept_statp" for a pointer to what the rfc (and wireshark, etc.) refer to as the "reply_stat".

| | | | | | | | | | | | | | | | The NFSACL patches introduced support for multiple RPC services listening on the same transport. However, only the first of these services was registered with portmapper. This was perfectly fine for nfsacl, as you traditionally do not want these to show up in a portmapper listing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are planning to increase RPCSVC_MAXPAGES from about 8 to about 256. This means we need to be a bit careful about arrays of size RPCSVC_MAXPAGES. struct svc_rqst contains two such arrays. However the there are never more that RPCSVC_MAXPAGES pages in the two arrays together, so only one array is needed. The two arrays are for the pages holding the request, and the pages holding the reply. Instead of two arrays, we can simply keep an index into where the first reply page is. This patch also removes a number of small inline functions that probably server to obscure what is going on rather than clarify it, and opencode the needed functionality. Also remove the 'rq_restailpage' variable as it is *always* 0. i.e. if the response 'xdr' structure has a non-empty tail it is always in the same pages as the head. check counters are initilised and incr properly check for consistant usage of ++ etc maybe extra some inlines for common approach general review Signed-off-by: Neil Brown <neilb@suse.de> Cc: Magnus Maatta <novell@kiruna.se> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

The new structure contains a lock which takes over several of the duties of svc_serv->sv_lock, which is now relegated to protecting only sv_tempsocks, sv_permsocks, and sv_tmpcnt in svc_serv. The point is to move the hottest fields out of svc_serv and into svc_pool, allowing a following patch to arrange for a svc_pool per NUMA node or per CPU.

* [PATCH] knfsd: move tempsock aging to a timerGreg Banks2006-10-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following are 11 patches from Greg Banks which combine to make knfsd more Numa-aware. They reduce hitting on 'global' data structures, and create some data-structures that can be node-local. knfsd threads are bound to a particular node, and the thread to handle a new request is chosen from the threads that are attach to the node that received the interrupt. The distribution of threads across nodes can be controlled by a new file in the 'nfsd' filesystem, though the default approach of an even spread is probably fine for most sites. Some (old) numbers that show the efficacy of these patches: N == number of NICs == number of CPUs == nmber of clients. Number of NUMA nodes == N/2 N Throughput, MiB/s CPU usage, % (max=N*100) Before After Before After --- ------ ---- ----- ----- 4 312 435 350 228 6 500 656 501 418 8 562 804 690 589 This patch: Move the aging of RPC/TCP connection sockets from the main svc_recv() loop to a timer which uses a mark-and-sweep algorithm every 6 minutes. This reduces the amount of work that needs to be done in the main RPC loop and the length of time we need to hold the (effectively global) svc_serv->sv_lock.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
