2008-02-069p: transport API reorganizationEric Van Hensbergen6-1145/+1187
This merges the mux.c (including the connection interface) with trans_fd in preparation for transport API changes. Ultimately, trans_fd will need to be rewritten to clean it up and simplify the implementation, but this reorganization is viewed as the first step.

Request from rusty: Just cleaning up patches for 2.6.25 merge, and noticed that net/9p/trans_virtio.c doesn't have a remove function. This will crash when removing the module (console doesn't have one because it can't really be removed). Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2008-02-069p: Convert semaphore to spinlock for p9_idpoolAnthony Liguori1-12/+8
When booting from v9fs, down_interruptible in p9_idpool_get() triggered a BUG as it was being called with IRQs disabled. A spinlock seems like the right thing to be using since the idr functions go out of their way not to sleep. This patch eliminates the BUG by converting the semaphore to a spinlock.

2008-02-05[SCTP]: Fix kernel panic while received AUTH chunk with BAD shared key ↵Wei Yongjun1-3/+3
identifier If SCTP-AUTH is enabled, received AUTH chunk with BAD shared key identifier will cause kernel panic. Test as following: step1: enabled /proc/sys/net/sctp/auth_enable step 2: connect to SCTP server with auth capable. Association is established between endpoints. Then send a AUTH chunk with a bad shareid, SCTP server will kernel panic after received that AUTH chunk. SCTP client SCTP server INIT ----------> (with auth capable) <---------- INIT-ACK (with auth capable) COOKIE-ECHO ----------> <---------- COOKIE-ACK AUTH ----------> AUTH chunk is like this: AUTH chunk Chunk type: AUTH (15) Chunk flags: 0x00 Chunk length: 28 Shared key identifier: 10 HMAC identifier: SHA-1 (1) HMAC: 0000000000000000000000000000000000000000 The assignment of NULL to key can safely be removed, since key_for_each (which is just list_for_each_entry under the covers does an initial assignment to key anyway). If the endpoint_shared_keys list is empty, or if the key_id being requested does not exist, the function as it currently stands returns the actuall list_head (in this case endpoint_shared_keys. Since that list_head isn't surrounded by an actuall data structure, the last iteration through list_for_each_entry will do a container_of on key, and we wind up returning a bogus pointer, instead of NULL, as we should. > Neil Horman wrote: >> On Tue, Jan 22, 2008 at 05:29:20PM +0900, Wei Yongjun wrote: >> >> FWIW, Ack from me.

git broken build) The 2.6 latest git build was broken when using the following configuration options: CONFIG_NET_EMATCH=n CONFIG_NET_CLS_FLOW=y with the following error: net/sched/cls_flow.c: In function 'flow_dump': net/sched/cls_flow.c:598: error: 'struct tcf_ematch_tree' has no member named 'hdr' make[2]: *** [net/sched/cls_flow.o] Error 1 make[1]: *** [net/sched] Error 2 make: *** [net] Error 2 see the recent post by Li Zefan: http://www.spinics.net/lists/netdev/msg54434.html The reason for this crash is that struct tcf_ematch_tree (net/pkt_cls.h) is empty when CONFIG_NET_EMATCH is not defined.

2008-02-04virtio: explicit enable_cb/disable_cb rather than callback return.Rusty Russell1-3/+1

2008-02-03[SOCK] proto: Add hashinfo member to struct protoArnaldo Carvalho de Melo10-93/+87
This way we can remove TCP and DCCP specific versions of sk->sk_prot->get_port: both v4 and v6 use inet_csk_get_port sk->sk_prot->hash: inet_hash is directly used, only v6 need a specific version to deal with mapped sockets sk->sk_prot->unhash: both v4 and v6 use inet_hash directly struct inet_connection_sock_af_ops also gets a new member, bind_conflict, so that inet_csk_get_port can find the per family routine. Now only the lookup routines receive as a parameter a struct inet_hashtable. With this we further reuse code, reducing the difference among INET transport protocols. Eventually work has to be done on UDP and SCTP to make them share this infrastructure and get as a bonus inet_diag interfaces so that iproute can be used with these protocols. net-2.6/net/ipv4/inet_hashtables.c: struct proto | +8 struct inet_connection_sock_af_ops | +8 2 structs changed __inet_hash_nolisten | +18 __inet_hash | -210 inet_put_port | +8 inet_bind_bucket_create | +1 __inet_hash_connect | -8 5 functions changed, 27 bytes added, 218 bytes removed, diff: -191 net-2.6/net/core/sock.c: proto_seq_show | +3 1 function changed, 3 bytes added, diff: +3 net-2.6/net/ipv4/inet_connection_sock.c: inet_csk_get_port | +15 1 function changed, 15 bytes added, diff: +15 net-2.6/net/ipv4/tcp.c: tcp_set_state | -7 1 function changed, 7 bytes removed, diff: -7 net-2.6/net/ipv4/tcp_ipv4.c: tcp_v4_get_port | -31 tcp_v4_hash | -48 tcp_v4_destroy_sock | -7 tcp_v4_syn_recv_sock | -2 tcp_unhash | -179 5 functions changed, 267 bytes removed, diff: -267 net-2.6/net/ipv6/inet6_hashtables.c: __inet6_hash | +8 1 function changed, 8 bytes added, diff: +8 net-2.6/net/ipv4/inet_hashtables.c: inet_unhash | +190 inet_hash | +242 2 functions changed, 432 bytes added, diff: +432 vmlinux: 16 functions changed, 485 bytes added, 492 bytes removed, diff: -7 /home/acme/git/net-2.6/net/ipv6/tcp_ipv6.c: tcp_v6_get_port | -31 tcp_v6_hash | -7 tcp_v6_syn_recv_sock | -9 3 functions changed, 47 bytes removed, diff: -47 /home/acme/git/net-2.6/net/dccp/proto.c: dccp_destroy_sock | -7 dccp_unhash | -179 dccp_hash | -49 dccp_set_state | -7 dccp_done | +1 5 functions changed, 1 bytes added, 242 bytes removed, diff: -241 /home/acme/git/net-2.6/net/dccp/ipv4.c: dccp_v4_get_port | -31 dccp_v4_request_recv_sock | -2 2 functions changed, 33 bytes removed, diff: -33 /home/acme/git/net-2.6/net/dccp/ipv6.c: dccp_v6_get_port | -31 dccp_v6_hash | -7 dccp_v6_request_recv_sock | +5 3 functions changed, 5 bytes added, 38 bytes removed, diff: -33 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

2008-02-01rdma: SVCRDMA sendtoTom Tucker1-0/+520
This file implements the RDMA transport sendto function. A RPC reply on an RDMA transport consists of some number of RDMA_WRITE requests followed by an RDMA_SEND request. The sendto function parses the ONCRPC RDMA reply header to determine how to send the reply back to the client. The send queue is sized so as to be able to send complete replies for requests in most cases. In the event that there are not enough SQ WR slots to reply, e.g. big data, the send will block the NFSD thread. The I/O callback functions in svc_rdma_transport.c that reap WR completions wake any waiters blocked on the SQ. In general, the goal is not to block NFSD threads and the has_wspace method stall requests when the SQ is nearly full.

2008-02-01rdma: SVCRDMA recvfromTom Tucker1-0/+586
This file implements the RDMA transport recvfrom function. The function dequeues work reqeust completion contexts from an I/O list that it shares with the I/O tasklet in svc_rdma_transport.c. For ONCRPC RDMA, an RPC may not be complete when it is received. Instead, the RDMA header that precedes the RPC message informs the transport where to get the RPC data from on the client and where to place it in the RPC message before it is delivered to the server. The svc_rdma_recvfrom function therefore, parses this RDMA header and issues any necessary RDMA operations to fetch the remainder of the RPC from the client. Special handling is required when the request involves an RDMA_READ. In this case, recvfrom submits the RDMA_READ requests to the underlying transport driver and then returns 0. When the transport completes the last RDMA_READ for the request, it enqueues it on a read completion queue and enqueues the transport. The recvfrom code favors this queue over the regular DTO queue when satisfying reads. Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Acked-by: Neil Brown <neilb@suse.de> Signed-off-by: J.

2008-02-01rdma: SVCRDMA Core Transport ServicesTom Tucker1-0/+1080
This file implements the core transport data management and I/O path. The I/O path for RDMA involves receiving callbacks on interrupt context. Since all the svc transport locks are _bh locks we enqueue the transport on a list, schedule a tasklet to dequeue data indications from the RDMA completion queue. The tasklet in turn takes _bh locks to enqueue receive data indications on a list for the transport. The svc_rdma_recvfrom transport function dequeues data from this list in an NFSD thread context.

2008-02-01svc: Add svc_xprt_names service to replace svc_sock_namesTom Tucker1-0/+35
Create a transport independent version of the svc_sock_names function. The toclose capability of the svc_sock_names service can be implemented using the svc_xprt_find and svc_xprt_close services.
