2008-04-04[IPV6] ADDRCONF: Fix array size for sysctls.YOSHIFUJI Hideaki
We have been using __NET_IPV6_MAX for adjusting the size of array for sysctl table, but it does not work any longer because of the deprecation of NET_IPV6_xxx constants. Let's use DEVCONF_MAX instead. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>

2008-04-03[NETNS]: Inet control socket should not hold a namespace.Denis V. Lunev

2008-04-02IPv6: do not create temporary adresses with too short preferred lifetimeBenoit Boissinot

2008-03-31[SOCK][NETNS]: Add a struct net argument to sock_prot_inuse_add and _get.Pavel Emelyanov
This counter is about to become per-proto-and-per-net, so we'll need two arguments to determine which cell in this "table" to work with. All the places, but proc already pass proper net to it - proc will be tuned a bit later. Some indentation with spaces in proc files is done to keep the file coding style consistent.

2008-03-31[IPV6] MCAST: Ensure to check multicast listener(s).YOSHIFUJI Hideaki
In ip6_mc_input(), we need to check whether we have listener(s) for the packet. After commit ae7bf20a6316272acfcaef5d265b18aaa54b41e4, all packets for multicast destinations are delivered to upper layer if IFF_PROMISC or IFF_ALLMULTI is set. In fact, bug was rather ancient; the original (before the commit) intent of the dev->flags check was to skip the ipv6_chk_mcast_addr() call, assuming L2 filters packets appropriately, but it was even not true. Let's explicitly check our multicast list. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Acked-by: David L Stevens <dlstevens@us.ibm.com> Signed-off-by: David S.

2008-03-27[ESP]: Ensure IV is in linear part of the skb to avoid BUG() due to OOB accessThomas Graf
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 Xu
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. Thanks to Joakim Koskela for finding this problem. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-03-26[IPV6]: Fix potential net leak and oops in ipv6 routing code.Pavel Emelyanov
The commits f3db4851 ([NETNS][IPV6] ip6_fib - fib6_clean_all handle several network namespaces) and 69ddb805 ([NETNS][IPV6] route6 - Make proc entry /proc/net/rt6_stats per namespace) made some proc files per net. Both of them introduced potential OOPS - get_proc_net can return NULL, but this check is lost - and a struct net leak - in case single_open() fails the previously got net is not put.
