2008-09-09ipvs: Embed user stats structure into kernel stats structureSven Wegener1-19/+2
Instead of duplicating the fields, integrate a user stats structure into the kernel stats structure. This is more robust when the members are changed, because they are now automatically kept in sync.

2008-09-09ipvs: Restrict connection table size via KconfigSven Wegener1-9/+1
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.

2008-09-09netns : fix kernel panic in timewait socket destructionDaniel Lezcano1-0/+3

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.

2008-08-11ipvs: Embed estimator object into stats objectSven Wegener1-2/+26
There's no reason for dynamically allocating an estimator object for every stats object. Directly embed an estimator object into every stats object and switch to using the kernel-provided list implementation. This makes the code much simpler and faster, as we do not need to traverse the list of all estimators to find the one belonging to a stats object. There's no need to use an rwlock, as we only have one reader. Also reorder the members of the estimator structure slightly to avoid padding overhead. This can't be done with the stats object as the members are currently copied to our user space object via memcpy() and changing it would break ABI.

2008-08-07tcp: Fix kernel panic when calling tcp_v(4/6)_md5_do_lookupGui Jianfeng1-1/+1
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.

2008-08-05ipv4: remove unused field in struct flowi (include/net/flow.h).Rami Rosen1-1/+0
This patch removes an unused field (flags) from struct flowi; it seems that this "flags" field was used once in the past for multipath routing with FLOWI_FLAG_MULTIPATHOLDROUTE flag (which does no longer exist); however, the "flags" field of struct flowi is not used anymore.
