* [INET]: Introduce inet_sk_rebuild_headerArnaldo Carvalho de Melo2005-08-291-5/+0
| | | | | | | | | | From tcp_v4_rebuild_header, that already was pretty generic, I only needed to use sk->sk_protocol instead of the hardcoded IPPROTO_TCP and establish the requirement that INET transport layer protocols that want to use this function map TCP_SYN_SENT to its equivalent state.

* [SOCK]: Introduce sk_setup_capsArnaldo Carvalho de Melo2005-08-291-5/+2
| | | | | | | | | From tcp_v4_setup_caps, that always is preceded by a call to __sk_dst_set, so coalesce this sequence into sk_setup_caps, removing one call to a TCP function in the IP layer.

* [NETFILTER]: reduce netfilter sk_buff enlargementHarald Welte2005-08-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed at netconf'05, we're trying to save every bit in sk_buff. The patch below makes sk_buff 8 bytes smaller. I did some basic testing on my notebook and it seems to work. The only real in-tree user of nfcache was IPVS, who only needs a single bit. Unfortunately I couldn't find some other free bit in sk_buff to stuff that bit into, so I introduced a separate field for them. Maybe the IPVS guys can resolve that to further save space. Initially I wanted to shrink pkt_type to three bits (PACKET_HOST and alike are only 6 values defined), but unfortunately the bluetooth code overloads pkt_type :( The conntrack-event-api (out-of-tree) uses nfcache, but Rusty just came up with a way how to do it without any skb fields, so it's safe to remove it. - remove all never-implemented 'nfcache' code - don't have ipvs code abuse 'nfcache' field. currently get's their own compile-conditional skb->ipvs_property field. IPVS maintainers can decide to move this bit elswhere, but nfcache needs to die. - remove skb->nfcache field to save 4 bytes - move skb->nfctinfo into three unused bits to save further 4 bytes Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S.

* [NETFILTER]: Fix connection tracking bug in 2.6.12Patrick McHardy2005-06-281-1/+7
| | | | | | | | | | | | | | | In 2.6.12 we started dropping the conntrack reference when a packet leaves the IP layer. This broke connection tracking on a bridge, because bridge-netfilter defers calling some NF_IP_* hooks to the bridge layer for locally generated packets going out a bridge, where the conntrack reference is no longer available. This patch keeps the reference in this case as a temporary solution, long term we will remove the defered hook calling. No attempt is made to drop the reference in the bridge-code when it is no longer needed, tc actions could already have sent the packet anywhere.

* [IPV4/IPV6] Ensure all frag_list members have NULL skHerbert Xu2005-05-181-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | Having frag_list members which holds wmem of an sk leads to nightmares with partially cloned frag skb's. The reason is that once you unleash a skb with a frag_list that has individual sk ownerships into the stack you can never undo those ownerships safely as they may have been cloned by things like netfilter. Since we have to undo them in order to make skb_linearize happy this approach leads to a dead-end. So let's go the other way and make this an invariant: For any skb on a frag_list, skb->sk must be NULL. That is, the socket ownership always belongs to the head skb. It turns out that the implementation is actually pretty simple. The above invariant is actually violated in the following patch for a short duration inside ip_fragment. This is OK because the offending frag_list member is either destroyed at the end of the slow path without being sent anywhere, or it is detached from the frag_list before being sent.

* [NETFILTER]: Drop conntrack reference when packet leaves IPPatrick McHardy2005-04-251-0/+2
| | | | | | | | | | | | | | In the event a raw socket is created for sending purposes only, the creator never bothers to check the socket's receive queue. But we continue to add skbs to its queue until it fills up. Unfortunately, if ip_conntrack is loaded on the box, each skb we add to the queue potentially holds a reference to a conntrack. If the user attempts to unload ip_conntrack, we will spin around forever since the queued skbs are pinned. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+1359
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
