* udp: Drop socket lock for encapsulated packetsHerbert Xu2008-08-09
| | | | | | | | | | | | | | The socket lock is there to protect the normal UDP receive path. Encapsulation UDP sockets don't need that protection. In fact the locking is deadly for them as they may contain another UDP packet within, possibly with the same addresses. Also the nested bit was copied from TCP. TCP needs it because of accept(2) spawning sockets. This simply doesn't apply to UDP so I've removed it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* tcp: Fix kernel panic when calling tcp_v(4/6)_md5_do_lookupGui Jianfeng2008-08-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the following packet flow happen, kernel will panic. MathineA MathineB SYN ----------------------> SYN+ACK <---------------------- ACK(bad seq) ----------------------> When a bad seq ACK is received, tcp_v4_md5_do_lookup(skb->sk, ip_hdr(skb)->daddr)) is finally called by tcp_v4_reqsk_send_ack(), but the first parameter(skb->sk) is NULL at that moment, so kernel panic happens. This patch fixes this bug.

| | | | | | | | | | | | | Here's a revised version, based on Herbert's comments, of a fix for the ipv4-inner, ipv6-outer interfamily ipsec beet mode. It fixes the network header adjustment during interfamily, as well as makes sure that we reserve enough room for the new ipv6 header if we might have something else as the inner family. Also, the ipv4 pseudo header construction was added. Signed-off-by: Joakim Koskela <jookos@gmail.com> Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* tcp: MD5: Fix IPv6 signaturesAdam Langley2008-08-01
| | | | | | | | | | | | | | | | | Reported by Stefanos Harhalakis; although 2.6.27-rc1 talks to itself using IPv6 TCP MD5 packets just fine, Stefanos noted that tcpdump claimed that the signatures were invalid. I broke this in 49a72dfb8814c2d65bd9f8c9c6daf6395a1ec58d ("tcp: Fix MD5 signatures for non-linear skbs"), it was just a typo. Note that tcpdump will still sometimes claim that the signatures are incorrect. A patch to tcpdump has been submitted for this[1].

* tcp: MD5: Fix MD5 signatures on certain ACK packetsAdam Langley2008-07-31
| | | | | | | | | | | | | | I noticed, looking at tcpdumps, that timewait ACKs were getting sent with an incorrect MD5 signature when signatures were enabled. I broke this in 49a72dfb8814c2d65bd9f8c9c6daf6395a1ec58d ("tcp: Fix MD5 signatures for non-linear skbs"). I didn't take into account that the skb passed to tcp_*_send_ack was the inbound packet, thus the source and dest addresses need to be swapped when calculating the MD5 pseudoheader.

* ipv6: Fix ip6_xmit to send fragments if ipfragok is trueWei Yongjun2008-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | SCTP used ip6_xmit() to send fragments after received ICMP packet too big message. But while send packet used ip6_xmit, the skb->local_df is not initialized. So when skb if enter ip6_fragment(), the following code will discard the skb. ip6_fragment(...) { if (!skb->local_df) { ... return -EMSGSIZE; } ... } SCTP do the following step: 1. send packet ip6_xmit(skb, ipfragok=0) 2. received ICMP packet too big message 3. if PMTUD_ENABLE: ip6_xmit(skb, ipfragok=1) This patch fixed the problem by set local_df if ipfragok is true.

* net: missing bits of net-namespace / sysctlAl Viro2008-07-27
| | | | | | | | | | | | | | | | | Piss-poor sysctl registration API strikes again, film at 11... What we really need is _pathname_ required to be present in already registered table, so that kernel could warn about bad order. That's the next target for sysctl stuff (and generally saner and more explicit order of initialization of ipv[46] internals wouldn't hurt either). For the time being, here are full fixups required by ..._rotable() stuff; we make per-net sysctl sets descendents of "ro" one and make sure that sufficient skeleton is there before we start registering per-net sysctls.
