Extend the XFRM framework so that endpoint address(es) in the XFRM databases could be dynamically updated according to a request (MIGRATE message) from user application. Target XFRM policy is first identified by the selector in the MIGRATE message. Next, the endpoint addresses of the matching templates and XFRM states are updated according to the MIGRATE message.

Do liberal tracking (only RSTs need to be in-window) for connections picked up without seeing a SYN to deal with window scaling. Also change logging of invalid packets not to log packets accepted by liberal tracking to avoid spamming the logs. Based on suggestion from James Ralston <ralston@pobox.com> Signed-off-by:

This is nf_conntrack_sane, a netfilter connection tracking helper module for the SANE protocol used by the 'saned' daemon to make scanners available via network. The SANE protocol uses separate control & data connections, similar to passive FTP. The helper module is needed to recognize the data connection as RELATED to the control one. Signed-off-by:

Add checksum default defines for mobility header(MH) which goes through raw socket. As the result kernel's behavior is to handle MH checksum as default. This patch also removes verifying inbound MH checksum at mip6_mh_filter() since it did not consider user specified checksum offset and was redundant check with raw socket code. Signed-off-by:

During an oprofile session of linux-2.6.20 on a dual opteron system, I noticed an expensive divide was done in tg3_poll(). I am using gcc-4.1.1, so the following comment from drivers/net/tg3.c seems over-optimistic : /* Do not place this n-ring entries value into the tp struct itself, * we really want to expose these constants to GCC so that modulo et * al. operations are done with shifts and masks instead of with * hw multiply/modulo instructions. Another solution would be to * replace things like '% foo' with '& (foo - 1)'. */ #define TG3_RX_RCB_RING_SIZE(tp) \ ((tp->tg3_flags2 & TG3_FLG2_5705_PLUS) ? 512 : 1024) Assembly code before patch : (oprofile results included) 6434 0.0088 :ffffffff803684b9: mov 0x6f0(%r15),%eax 587 8.0e-04 :ffffffff803684c0: and $0x40000,%eax 2170 0.0030 :ffffffff803684c5: cmp $0x1,%eax :ffffffff803684c8: lea 0x1(%r13),%eax :ffffffff803684cc: sbb %ecx,%ecx 2051 0.0028 :ffffffff803684ce: xor %edx,%edx :ffffffff803684d0: and $0x200,%ecx 20 2.7e-05 :ffffffff803684d6: add $0x200,%ecx 1986 0.0027 :ffffffff803684dc: div %ecx 103427 0.1410 :ffffffff803684de: cmp %edx,0xffffffffffffff7c(%rbp) Assembly code after the suggested patch : ffffffff803684b9: mov 0x6f0(%r15),%eax ffffffff803684c0: and $0x40000,%eax ffffffff803684c5: cmp $0x1,%eax ffffffff803684c8: sbb %eax,%eax ffffffff803684ca: inc %r13d ffffffff803684cd: and $0x200,%eax ffffffff803684d2: add $0x1ff,%eax ffffffff803684d7: and %eax,%r13d ffffffff803684da: cmp %r13d,0xffffffffffffff7c(%rbp) Signed-off-by:Eric Dumazet <dada1@cosmosbay.com> Acked-by:

This was reported by Ingo Molnar here, http://lkml.org/lkml/2006/12/18/119 The problem is that adummy_init() depends on atm_init() , but adummy_init() is called first. So I put atm_init() into subsys_initcall which seems appropriate, and it will still get module_init() if it becomes a module. Interesting to note that you could crash your system here if you just load the modules in the wrong order. Signed-off-by:

This patch introduces users of the round_jiffies() function in the networking code. These timers all were of the "about once a second" or "about once every X seconds" variety and several showed up in the "what wakes the cpu up" profiles that the tickless patches provide. Some timers are highly dynamic based on network load; but even on low activity systems they still show up so the rounding is done only in cases of low activity, allowing higher frequency timers in the high activity case. The various hardware watchdogs are an obvious case; they run every 2 seconds but aren't otherwise specific of exactly when they need to run. Signed-off-by:

We clear the unused parts of the SACK cache, This prevents us from mistakenly taking the cache data if the old data in the SACK cache is the same as the data in the SACK block. This assumes that we never receive an empty SACK block with start and end both at zero. Signed-off-by:

Move DSACK code outside the SACK fast-path checking code. If the DSACK determined that the information was too old we stayed with a partial cache copied. Most likely this matters very little since the next packet will not be DSACK and we will find it in the cache. but it's still not good form and there is little reason to couple the two checks. Since the SACK receive cache doesn't need the data to be in host order we also remove the ntohl in the checking loop. Signed-off-by:

Only advance the SACK fast-path pointer for the first block, the fast-path assumes that only the first block advances next time so we should not move the cached skb for the next sack blocks. Signed-off-by:

Both aux data and sockaddr tries to use the same buffer which obviously doesn't work. We just happen to have 4 bytes free in the skb->cb if you take away the maximum length of sockaddr_ll. That's just enough to store the one piece of info from aux data that we can't generate at recvmsg(2) time. This is what the following patch does. Signed-off-by:

This patch is needed to make ISC's DHCP server (and probably other DHCP servers/clients using AF_PACKET) to be able to serve another client on the same Xen host. The problem is that packets between different domains on the same Xen host only have partial checksums. Unfortunately this piece of information is not passed along in AF_PACKET unless you're using the mmap interface. Since dhcpd doesn't support packet-mmap, UDP packets from the same host come out with apparently bogus checksums. This patch adds a mechanism for AF_PACKET recvmsg(2) to return the status along with the packet. It does so by adding a new cmsg that contains this information along with some other relevant data such as the original packet length. I didn't include the time stamp information since there is already a cmsg for that. This patch also changes the mmap code to set the CSUMNOTREADY flag on all packets instead of just outoing packets on cooked sockets. Signed-off-by:
