Raw Normal View History

Linux-2.6.12-rc2 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!

[IPV4]: Uninline netfilter okfns Now that we don't pass double skb pointers to nf_hook_slow anymore, gcc can generate tail calls for some of the netfilter hook okfn invocations, so there is no need to inline the functions anymore. This caused huge code bloat since we ended up with one inlined version and one out-of-line version since we pass the address to nf_hook_slow. Before: text data bss dec hex filename 8997385 1016524 524652 10538561 a0ce41 vmlinux After: text data bss dec hex filename 8994009 1016524 524652 10535185 a0c111 vmlinux ------------------------------------------------------- -3376 All cases have been verified to generate tail-calls with and without netfilter. The okfns in ipmr and xfrm4_input still remain inline because gcc can't generate tail-calls for them. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

[NET]: Allow forwarding of ip_summed except CHECKSUM_COMPLETE Right now Xen has a horrible hack that lets it forward packets with partial checksums. One of the reasons that CHECKSUM_PARTIAL and CHECKSUM_COMPLETE were added is so that we can get rid of this hack (where it creates two extra bits in the skbuff to essentially mirror ip_summed without being destroyed by the forwarding code). I had forgotten that I've already gone through all the deivce drivers last time around to make sure that they're looking at ip_summed == CHECKSUM_PARTIAL rather than ip_summed != 0 on transmit. In any case, I've now done that again so it should definitely be safe. Unfortunately nobody has yet added any code to update CHECKSUM_COMPLETE values on forward so we I'm setting that to CHECKSUM_NONE. This should be safe to remove for bridging but I'd like to check that code path first. So here is the patch that lets us get rid of the hack by preserving ip_summed (mostly) on forwarded packets.

[IPV4] IPSEC: Omit redirect for tunnelled packet. IPv4 IPsec tunnel gateway incorrectly sends redirect to sender if it is onlink host when network device the IPsec tunnelled packet is arrived is the same as the one the decapsulated packet is sent. With this patch, it omits to send the redirect when the forwarding skbuff carries secpath, since such skbuff should be assumed as a decapsulated packet from IPsec tunnel by own. Request for comments: Alternatively we'd have another way to change net/ipv4/route.c (__mkroute_input) to use RTCF_DOREDIRECT flag unless skbuff has no secpath. It is better than this patch at performance point of view because IPv4 redirect judgement is done at routing slow-path. However, it should be taken care of resource changes between SAD(XFRM states) and routing table. In other words, When IPv4 SAD is changed does the related routing entry go to its slow-path? If not, it is reasonable to apply this patch. Signed-off-by: Masahide NAKAMURA <nakam@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>
