| | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a replacement for the in-kernel portmapper client that supports all 3 versions of the rpcbind protocol. This code is not used yet.

| * SUNRPC: Eliminate side effects from rpc_mallocChuck Lever2007-05-013-33/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently rpc_malloc sets req->rq_buffer internally. Make this a more generic interface: return a pointer to the new buffer (or NULL) and make the caller set req->rq_buffer and req->rq_bufsize. This looks much more like kmalloc and eliminates the side effects. To fix a potential deadlock, this patch also replaces GFP_NOFS with GFP_NOWAIT in rpc_malloc. This prevents async RPCs from sleeping outside the RPC's task scheduler while allocating their buffer.

| * SUNRPC: RPC buffer size estimates are too largeChuck Lever2007-05-013-28/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RPC buffer size estimation logic in net/sunrpc/clnt.c always significantly overestimates the requirements for the buffer size. A little instrumentation demonstrated that in fact rpc_malloc was never allocating the buffer from the mempool, but almost always called kmalloc. To compute the size of the RPC buffer more precisely, split p_bufsiz into two fields; one for the argument size, and one for the result size. Then, compute the sum of the exact call and reply header sizes, and split the RPC buffer precisely between the two. That should keep almost all RPC buffers within the 2KiB buffer mempool limit. And, we can finally be rid of RPC_SLACK_SPACE! Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* | [SCTP]: Set assoc_id correctly during INIT collision.Vlad Yasevich2007-05-044-31/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the INIT/COOKIE-ACK collision cases, it's possible to get into a situation where the association id is not yet set at the time of the user event generation. As a result, user events have an association id set to 0 which will confuse applications. This happens if we hit case B of duplicate cookie processing. In the particular example found and provided by Oscar Isaula <Oscar.Isaula@motorola.com>, flow looks like this: A B ---- INIT-------> (lost) <---------INIT------ ---- INIT-ACK---> <------ Cookie ECHO When the Cookie Echo is received, we end up trying to update the association that was created on A as a result of the (lost) INIT, but that association doesn't have the ID set yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sort out the MTU determination and handling in AF_RXRPC: (1) If it's present, parse the additional information supplied by the peer at the end of the ACK packet (struct ackinfo) to determine the MTU sizes that peer is willing to support. (2) Initialise the MTU size to that peer from the kernel's routing records. (3) Send ACKs rather than ACKALLs as the former carry the additional info, and the latter do not. (4) Declare the interface MTU size in outgoing ACKs as a maximum amount of data that can be stuffed into an RxRPC packet without it having to be fragmented to come in this computer's NIC. (5) If sendmsg() is given MSG_MORE then it should allocate an skb of the maximum size rather than one just big enough for the data it's got left to process on the theory that there is more data to come that it can append to that packet. This means, for example, that if AFS does a large StoreData op, all the packets barring the last will be filled to the maximum unfragmented size.

* | [TCP]: zero out rx_opt in tcp_disconnect()Srinivas Aji2007-05-041-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the server drops its connection, NFS client reconnects using the same socket after disconnecting. If the new connection's SYN,ACK doesn't contain the TCP timestamp option and the old connection's did, tp->tcp_header_len is recomputed assuming no timestamp header but tp->rx_opt.tstamp_ok remains set. Then tcp_build_and_update_options() adds in a timestamp option past the end of the allocated TCP header, overwriting TCP data, or when the data is in skb_shinfo(skb)->frags[], overwriting skb_shinfo(skb) causing a crash soon after. (The issue was debugged from such a crash.) Similarly, wscale_ok and sack_ok also get set based on the SYN,ACK packet but not reset on disconnect, since they are zeroed out at initialization. The patch zeroes out the entire tp->rx_opt struct in tcp_disconnect() to avoid this sort of problem. Signed-off-by: Srinivas Aji <Aji_Srinivas@emc.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I needed to use this recently to talk to a Cisco server. In my case I only did SNAT while the Cisco server used a different address for RTP traffic than the one for SIP. I discovered that nf_nat_sip NATed the RTP address to the SIP one which was unnecessary but OK. However, in doing so it did not DNAT the destination address on the RTP traffic to the Cisco back to the original RTP address. This patch corrects this by noting down the RTP address and using it when the expectation fires.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While porting some changes of the 2.6.21-rc7 pptp/proto_gre conntrack and nat modules to a 2.4.32 kernel I noticed that the gre_key function returns a wrong pointer to the GRE key of a version 0 packet thus corrupting the packet payload. The intended behaviour for GREv0 packets is to act like nf_conntrack_proto_generic/nf_nat_proto_unknown so I have ripped the offending functions (not used anymore) and modified the nf_nat_proto_gre modules to not touch version 0 (non PPTP) packets.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On MIPv6 usage, XFRM sub policy is enabled. When main (IPsec) and sub (MIPv6) policy selectors have the same address set but different upper layer information (i.e. protocol number and its ports or type/code), multiple bundle should be created. However, currently we have issue to use the same bundle created for the first time with all flows covered by the case. It is useful for the bundle to have the upper layer information to be restructured correctly if it does not match with the flow. 1. Bundle was created by two policies Selector from another policy is added to xfrm_dst. If the flow does not match the selector, it goes to slow path to restructure new bundle by single policy. 2. Bundle was created by one policy Flow cache is added to xfrm_dst as originated one. If the flow does not match the cache, it goes to slow path to try searching another policy.

| * [PATCH] INET : IPV4 UDP lookups converted to a 2 pass algoEric Dumazet2007-04-301-57/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some people want to have many UDP sockets, binded to a single port but many different addresses. We currently hash all those sockets into a single chain. Processing of incoming packets is very expensive, because the whole chain must be examined to find the best match. I chose in this patch to hash UDP sockets with a hash function that take into account both their port number and address : This has a drawback because we need two lookups : one with a given address, one with a wildcard (null) address.

| * [AF_IUCV/IUCV]: smp_call_function deadlockMartin Schwidefsky2007-04-291-73/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling smp_call_function can lead to a deadlock if it is called from tasklet context. Fixing this deadlock requires to move the smp_call_function from the tasklet context to a work queue. To do that queue the path pending interrupts to a separate list and move the path cleanup out of iucv_path_sever to iucv_path_connect and iucv_path_pending. This creates a new requirement for iucv_path_connect: it may not be called from tasklet context anymore. Also fixed compile problem for CONFIG_HOTPLUG_CPU=n and another one when walking the cpu_online mask. When doing this, we must disable cpu hotplug.

| * [TCP]: Update references in two old commentsGerrit Renker2007-04-292-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | This updates references to drafts in comments which must be about 10 years old. Internet draft draft-ietf-tcpimpl-prob-03.txt expired in 1998 and was replaced by RFC 2525 in March 1999. Section 3.10 of the draft maps almost identically into section 2.17 of RFC 2525: both are entitled "Failure to RST on close with data pending", the differences in text body amount to a typo and minor sentence change.
