Reuse the existing logic for multicast list synchronization for the unicast address list. The core of dev_mc_sync/unsync are split out as __dev_addr_sync/unsync and moved from dev_mcast.c to dev.c. These are then used to implement dev_unicast_sync/unsync as well. I'm working on cleaning up Intel's FCoE stack, which generates new MAC addresses from the fibre channel device id assigned by the fabric as per the current draft specification in T11. When using such a protocol in a VLAN environment it would be nice to not always be forced into promiscuous mode, assuming the underlying Ethernet driver supports multiple unicast addresses as well.

In strategy_allowed_congestion_control of the 2.6.24 kernel, when sysctl_string return 1 on success,it should call tcp_set_allowed_congestion_control to set the allowed congestion control.But, it don't. the sysctl_string return 1 on success, otherwise return negative, never return 0.The patch fix the problem.

Normally during a dump the key of the last dumped entry is used for continuation, but since lock is dropped it might be lost. In that case fallback to the old counter based N^2 behaviour. This means the dump will end up skipping some routes which matches what FIB_HASH does. Signed-off-by:

- Remove an unused definition (LAT_BUCKETS_MAX) in net/core/pktgen.c. - Remove the corresponding comment. - The LAT_BUCKETS_MAX seems to have to do with a patch from a long time ago which was not applied (Ben Greear), which dealt with latency counters.

This is needed because in ndisc.c, we have: static void ndisc_router_discovery(struct sk_buff *skb) { // ... if (ndopts.nd_opts_mtu) { // ... if (rt) rt->u.dst.metrics[RTAX_MTU-1] = mtu; rt6_mtu_change(skb->dev, mtu); // ... } Since the mtu is set directly here, rt6_mtu_change_route thinks that it is unchanged, and so it fails to update the MSS accordingly. This patch lets rt6_mtu_change_route still update MSS if old_mtu == new_mtu. Signed-off-by:Jim Paris <jim@jtan.com> Signed-off-by:

Add a net argument to inet_lookup and propagate it further into lookup calls. Plus tune the __inet_check_established. The dccp and inet_diag, which use that lookup functions pass the init_net into them. Signed-off-by:

This tags the inet_bind_bucket struct with net pointer, initializes it during creation and makes a filtering during lookup. A better hashfn, that takes the net into account is to be done in the future, but currently all bind buckets with similar port will be in one hash chain. Signed-off-by:

These two functions are the same except for what they call to "check_established" and "hash" for a socket.

We have INET_MATCH, INET_TW_MATCH and INET6_MATCH to test sockets and twbuckets for matching, but ipv6 twbuckets are tested manually. Here's the INET6_TW_MATCH to help with it. Signed-off-by:

There are many small but still wrong things with /proc/net/*_tables_* so I decided to do overhaul simultaneously making it more suitable for per-netns /proc/net/*_tables_* implementation. Fix a) xt_get_idx() duplicating now standard seq_list_start/seq_list_next iterators b) tables/matches/targets list was chosen again and again on every ->next c) multiple useless "af >= NPROTO" checks -- we simple don't supply invalid AFs there and registration function should BUG_ON instead. Regardless, the one in ->next() is the most useless -- ->next doesn't run at all if ->start fails. d) Don't use mutex_lock_interruptible() -- it can fail and ->stop is executed even if ->start failed, so unlock without lock is possible. As side effect, streamline code by splitting xt_tgt_ops into xt_target_ops, xt_matches_ops, xt_tables_ops. xt_tables_ops hooks will be changed by per-netns code. Code of xt_matches_ops, xt_target_ops is identical except the list chosen for iterating, but I think consolidating code for two files not worth it given "<< 16" hacks needed for it.

Introduces the xt_hashlimit match revision 1. It adds support for kernel-level inversion and grouping source and/or destination IP addresses, allowing to limit on a per-subnet basis. While this would technically obsolete xt_limit, xt_hashlimit is a more expensive due to the hashbucketing. Kernel-level inversion: Previously you had to do user-level inversion: iptables -N foo iptables -A foo -m hashlimit --hashlimit(-upto) 5/s -j RETURN iptables -A foo -j DROP iptables -A INPUT -j foo now it is simpler: iptables -A INPUT -m hashlimit --hashlimit-over 5/s -j DROP Signed-off-by:

nf_ct_tuple_src_equal() and nf_ct_tuple_dst_equal() both compare the protocol numbers. Unfortunately gcc doesn't optimize out the second comparison, so remove it and prefix both functions with __ to indicate that they should not be used directly.
