commit 0794935e "[NETFILTER]: nf_conntrack: optimize hash_conntrack()" results in ARM platforms hashing uninitialised padding. This padding doesn't exist on other architectures. Fix this by replacing NF_CT_TUPLE_U_BLANK() with memset() to ensure everything is initialised. There were only 4 bytes that NF_CT_TUPLE_U_BLANK() wasn't clearing anyway (or 12 bytes on ARM).

Add struct net_device parameter to ip_rt_frag_needed() and update MTU to cache entries where ifindex is specified. This is similar to what is already done in ip_rt_redirect(). Signed-off-by:

This patch adds support for getsockopt for MCAST_MSFILTER for both IPv4 and IPv6. It depends on the previous setsockopt patch, and uses the same method. Signed-off-by:

1) added missing "__user" for kgsr and kgf pointers 2) verify read for only GROUP_FILTER_SIZE(0). The group_filter structure definition (via RFC) includes space for one source in the source list array, but that source need not be present. So, sizeof(group_filter) > GROUP_FILTER_SIZE(0). Fixed the user read-check for minimum length to use the smaller size. 3) remove unneeded "&" for gf_slist addresses Signed-off-by: -

Fixes bug http://bugzilla.kernel.org/show_bug.cgi?id=10556 where conn templates with protocol=IPPROTO_IP can oops backup box. Result from ip_vs_proto_get() should be checked because protocol value can be invalid or unsupported in backup. But for valid message we should not fail for templates which use IPPROTO_IP. Also, add checks to validate message limits and connection state. Show state NONE for templates using IPPROTO_IP. Signed-off-by:

There is a race condition when unloading bridge and netfilter. The problem happens if __fake_rtable is in use by a skb coming in, while someone starts to unload bridge.ko. br_netfilter_fini() is called at the beginning of unload in br_deinit() while skbs still are being forwarded and transferred to local ip stack. Thus there is a possibility of the __fake_rtable pointer not being removed in a skb that goes up to ip stack. This results in a kernel panic, as ip_rcv() calls the input-function of __fake_rtable, which is NULL. Moving the call of br_netfilter_fini() to the end of br_deinit() solves the problem.

AFAICT, it should ask for 'diff' instead of 'diff - skb_tailroom(e->skb)'. Because the resulting sk_buff has not enough space to support the skb_put(skb, diff) call a few lines later, this results in the call to skb_over_panic(). The patch below asks for allocation of a copy with enough space for mangled packet and the same amount of headroom as old sk_buff. While looking at how the regression appeared (e2b58a67), I noticed the same pattern in ipq_mangle_ipv6() and ipq_mangle_ipv4(). The patch corrects those locations too. Tested with bigger reinjected IPv6 packets (nfqnl_mangle() path), things are ok (2.6.25 and today's net-2.6 git tree). Signed-off-by:Arnaud Ebalard <arno@natisbad.org> Signed-off-by:

TBIPA needs to be set to a value (on connected MDIO buses) that doesn't conflict with PHYs on the bus. By hardcoding it to 0x1f, we were preventing boards with PHYs at 0x1f from working properly. Instead, scan the bus when it comes up, and find an address that doesn't have a PHY on it. The TBI PHY configuration code then trusts that the value in TBIPA is either safe, or doesn't matter (ie - it's not an active bus with other PHYs). Signed-off-by:
