2008-04-14[SKB]: __skb_append = __skb_queue_after Gerrit Renker1-1/+1
This expresses __skb_append in terms of __skb_queue_after, exploiting that __skb_append(old, new, list) = __skb_queue_after(list, old, new). Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-04-13[INET]: sk_reuse is valboolGerrit Renker1-2/+0
sk_reuse is declared as "unsigned char", but is set as type valbool in net/core/sock.c. There is no other place in net/ where sk->sk_reuse is set to a value > 1, so the test "sk_reuse > 1" can not be true. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S.

2008-04-10IPV4: use xor rather than multiple ands for route compareStephen Hemminger1-5/+5
The comparison in ip_route_input is a hot path, by recoding the C "and" as bit operations, fewer conditional branches get generated so the code should be faster.

2008-04-10[Syncookies]: Add support for TCP options via timestamps.Florian Westphal3-9/+91
Allow the use of SACK and window scaling when syncookies are used and the client supports tcp timestamps. Options are encoded into the timestamp sent in the syn-ack and restored from the timestamp echo when the ack is received. Based on earlier work by Glenn Griffin. This patch avoids increasing the size of structs by encoding TCP options into the least significant bits of the timestamp and by not using any 'timestamp offset'. The downside is that the timestamp sent in the packet after the synack will increase by several seconds. changes since v1: don't duplicate timestamp echo decoding function, put it into ipv4/syncookie.c and have ipv6/syncookies.c use it.

2008-04-10IPV4: fib_trie use vmalloc for large tnodesStephen Hemminger1-10/+15
Use vmalloc rather than alloc_pages to avoid wasting memory. The problem is that tnode structure has a power of 2 sized array, plus a header. So the current code wastes almost half the memory allocated because it always needs the next bigger size to hold that small header. This is similar to an earlier patch by Eric, but instead of a list and lock, I used a workqueue to handle the fact that vfree can't be done in interrupt context.

2008-03-27[ESP]: Ensure IV is in linear part of the skb to avoid BUG() due to OOB accessThomas Graf1-1/+1
ESP does not account for the IV size when calling pskb_may_pull() to ensure everything it accesses directly is within the linear part of a potential fragment. This results in a BUG() being triggered when the both the IPv4 and IPv6 ESP stack is fed with an skb where the first fragment ends between the end of the esp header and the end of the IV.

2008-03-26[IPSEC]: Fix BEET outputHerbert Xu2-6/+7
The IPv6 BEET output function is incorrectly including the inner header in the payload to be protected. This causes a crash as the packet doesn't actually have that many bytes for a second header. The IPv4 BEET output on the other hand is broken when it comes to handling an inner IPv6 header since it always assumes an inner IPv4 header. This patch fixes both by making sure that neither BEET output function touches the inner header at all. All access is now done through the protocol-independent cb structure. Two new attributes are added to make this work, the IP header length and the IPv4 option length. They're filled in by the inner mode's output function.

Fix it bu going to a proper label. Found after net namespace's lo refused to unregister :) Many thanks to Den for valuable help during debugging.
