[UDP]: Revert 2-pass hashing changes.

2007-06-07T20:40:50Z

This reverts changesets: 6aaf47fa48d3c44280810b1b470261d340e4ed87 b7b5f487ab39bc10ed0694af35651a03d9cb97ff de34ed91c4ffa4727964a832c46e624dd1495cf5 fc038410b4b1643766f8033f4940bcdb1dace633 There are still some correctness issues recently discovered which do not have a known fix that doesn't involve doing a full hash table scan on port bind. So revert for now. Signed-off-by: David S. Miller

[XFRM]: Allow packet drops during larval state resolution.

2007-05-25T01:17:54Z

The current IPSEC rule resolution behavior we have does not work for a lot of people, even though technically it's an improvement from the -EAGAIN buisness we had before. Right now we'll block until the key manager resolves the route. That works for simple cases, but many folks would rather packets get silently dropped until the key manager resolves the IPSEC rules. We can't tell these folks to "set the socket non-blocking" because they don't have control over the non-block setting of things like the sockets used to resolve DNS deep inside of the resolver libraries in libc. With that in mind I coded up the patch below with some help from Herbert Xu which provides packet-drop behavior during larval state resolution, controllable via sysctl and off by default. This lays the framework to either: 1) Make this default at some point or... 2) Move this logic into xfrm{4,6}_policy.c and implement the ARP-like resolution queue we've all been dreaming of. The idea would be to queue packets to the policy, then once the larval state is resolved by the key manager we re-resolve the route and push the packets out. The packets would timeout if the rule didn't get resolved in a certain amount of time. Signed-off-by: David S. Miller

[UDP]: Fix AF-specific references in AF-agnostic code.

2007-05-11T06:47:22Z

__udp_lib_port_inuse() cannot make direct references to inet_sk(sk)->rcv_saddr as that is ipv4 specific state and this code is used by ipv6 too. Use an operations vector to solve this, and this also paves the way for ipv6 support for non-wild saddr hashing in UDP. Signed-off-by: David S. Miller

[NET]: Treat CHECKSUM_PARTIAL as CHECKSUM_UNNECESSARY

2007-04-26T05:28:43Z

When a transmitted packet is looped back directly, CHECKSUM_PARTIAL maps to the semantics of CHECKSUM_UNNECESSARY. Therefore we should treat it as such in the stack. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller

[SK_BUFF]: Introduce ipv6_hdr(), remove skb->nh.ipv6h

2007-04-26T05:25:14Z

Now the skb->nh union has just one member, .raw, i.e. it is just like the skb->mac union, strange, no? I'm just leaving it like that till the transport layer is done with, when we'll rename skb->mac.raw to skb->mac_header (or ->mac_header_offset?), ditto for ->{h,nh}.

[UDP]: Clean up UDP-Lite receive checksum

2007-04-26T05:23:51Z

This patch eliminates some duplicate code for the verification of receive checksums between UDP-Lite and UDP. It does this by introducing __skb_checksum_complete_head which is identical to __skb_checksum_complete_head apart from the fact that it takes a length parameter rather than computing the first skb->len bytes. As a result UDP-Lite will be able to use hardware checksum offload for packets which do not use partial coverage checksums. It also means that UDP-Lite loopback no longer does unnecessary checksum verification. If any NICs start support UDP-Lite this would also start working automatically. This patch removes the assumption that msg_flags has MSG_TRUNC clear upon entry in recvmsg. Signed-off-by: Herbert Xu Signed-off-by: David S. Miller
