* [AF_RXRPC]: Sort out MTU handling.David Howells2007-05-044-14/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | With the inital implementation we missed to implement a skb backlog queue . The result is that socket receive processing tossed packets. Since AF_IUCV connections are working synchronously it leads to connection hangs. Problems with read, close and select also occured. Using a skb backlog queue is fixing all of these problems .

Shrinks by 8 bytes sizeof(struct ip6_flowlabel) 2) ipv6_addr_cmp() and ipv6_addr_copy() dont need (void *) casts : Compiler might take into account natural alignement of in6_addr structs to emit better code for memcpy()/memcmp() Casts to (void *) force byte accesses. 3) ipv6_addr_prefix() optimization : Better to clear whole struct, as compiler can emit better code for memset(addr, 0, 16) (2 stores on x86_64), and avoid some conditional branches. # size vmlinux.after vmlinux.before text data bss dec hex filename 5262262 647612 557432 6467306 62aeea vmlinux.after 5262550 647612 557432 6467594 62b00a vmlinux.before thats 288 bytes saved.

* [TCP]: zero out rx_opt in tcp_disconnect()Srinivas Aji2007-05-031-2/+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.

| | | | | | | | | | | | | Remove the check for skb->len greater than MTU when doing TSO. When the destination has a smaller MSS than the source, a TSO packet may be smaller than the MTU at the source and we still need to process it as a TSO packet.

* [NETFILTER]: sip: Fix RTP address NATHerbert Xu2007-05-031-1/+25
| | | | | | | | | | | | | | | | 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.

* [NETFILTER]: nf_nat_proto_gre: do not modify/corrupt GREv0 packets through NATJorge Boncompte2007-05-032-30/+8
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | TCP has a transitional state when SACK is not in use during which this invariant is temporarily broken. Without SACK, tcp_clean_rtx_queue does not decrement sacked_out. Therefore calls to tcp_sync_left_out before sacked_out is again corrected by tcp_fastretrans_alert can trigger this trap as sacked_out still has couple of segments that are already out of window.

(2) Rather than using an array size of 6 in some places and an array size of ETH_ALEN in others, pass a pointer instead and pass the array size through so that we can actually check it. (3) Do the buffer fill count check before checking the for_primary_ifa condition again. This permits us to skip that check should maxbufs be reached before we run out of interfaces.

* libata: honour host controllers that want just one hostLinus Torvalds2007-04-301-7/+4
| | | | | | | | | | | | | | | | | | | | The Marvell IDE interface on my machine would hit a BUG_ON() in lib/iomem.c because it was calling ata_pci_init_one() specifying just a single port on the host, but that would actually end up trying to initialize two ports, the second one with bogus information. This fixes "ata_pci_init_one()" so that it actually passes down the n_ports variable that it got from the low-level driver to the host allocation routine ("ata_host_alloc_pinfo()"), which results in the ATA layer actually having the correct port number information. And in order to make it all work, I also needed to fix a few places that had incorrectly hard-coded the fact that a host always had exactly two ports (both ata_pci_init_bmdma() and ata_request_legacy_irqs() would just always iterate over both ports).
