2008-09-09ipvs: Restrict connection table size via KconfigSven Wegener
Instead of checking the value in include/net/ip_vs.h, we can just restrict the range in our Kconfig file. This will prevent values outside of the range early.

2008-09-09IPVS: Remove incorrect ip_route_me_harder(), fix IPv6Julius Volz
Remove an incorrect ip_route_me_harder() that was probably a result of merging my IPv6 patches with the local client patches. With this, IPv6+NAT are working again. Signed-off-by: Julius Volz <juliusv@google.com> Signed-off-by: Simon Horman <horms@verge.net.au>
2008-09-09ipvs: handle PARTIAL_CHECKSUMSimon Horman
Now that LVS can load balance locally generated traffic, packets may come from the loopback device and thus may have a partial checksum. The existing code allows for the case where there is no checksum at all for TCP, however Herbert Xu has confirmed that this is not legal.

2008-09-08netns : fix kernel panic in timewait socket destructionDaniel Lezcano

The timewait sockets life cycle is not tied with the network namespace, that means the timewait sockets stay alive while the network namespace dies. The timewait sockets are for avoiding to receive a duplicate packet from the network, if the network namespace is freed, the network stack is removed, so no chance to receive any packets from the outside world. Furthermore, having a pending destruction timer on these sockets with a network namespace freed is not safe and will lead to an oops if the timer callback which try to access data belonging to the namespace like for example in: inet_twdr_do_twkill_work -> NET_INC_STATS_BH(twsk_net(tw), LINUX_MIB_TIMEWAITED); Purging the timewait sockets at the network namespace destruction will: 1) speed up memory freeing for the namespace 2) fix kernel panic on asynchronous timewait destruction Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Acked-by: Denis V.

2008-08-28tcp: Skip empty hash buckets faster in /proc/net/tcpAndi Kleen
On most systems most of the TCP established/time-wait hash buckets are empty. When walking the hash table for /proc/net/tcp their read locks would always be aquired just to find out they're empty. This patch changes the code to check first if the buckets have any entries before taking the lock, which is much cheaper than taking a lock. Since the hash tables are large this makes a measurable difference on processing /proc/net/tcp, especially on architectures with slow read_lock (e.g. PPC) On a 2GB Core2 system time cat /proc/net/tcp > /dev/null (with a mostly empty hash table) goes from 0.046s to 0.005s. On systems with slower atomics (like P4 or POWER4) or larger hash tables (more RAM) the difference is much higher. This can be noticeable because there are some daemons around who regularly scan /proc/net/tcp. Original idea for this patch from Marcus Meissner, but redone by me.
