sysctl: simplify ->strategy

2008-10-16T18:21:47Z

name and nlen parameters passed to ->strategy hook are unused, remove them. In general ->strategy hook should know what it's doing, and don't do something tricky for which, say, pointer to original userspace array may be needed (name).

inet: cleanup of local_port_range

2008-10-08T21:18:04Z

I noticed sysctl_local_port_range[] and its associated seqlock sysctl_local_port_range_lock were on separate cache lines. Moreover, sysctl_local_port_range[] was close to unrelated variables, highly modified, leading to cache misses. Moving these two variables in a structure can help data locality and moving this structure to read_mostly section helps sharing of this data among cpus. Cleanup of extern declarations (moved in include file where they belong), and use of inet_get_local_port_range() accessor instead of direct access to ports values.

ipv4: Make Netfilter's ip_route_me_harder() non-local address compatible

2008-10-01T14:44:42Z

Netfilter's ip_route_me_harder() tries to re-route packets either generated or re-routed by Netfilter. This patch changes ip_route_me_harder() to handle packets from non-locally-bound sockets with IP_TRANSPARENT set as local and to set the appropriate flowi flags when re-doing the routing lookup.

tcp: Handle TCP SYN+ACK/ACK/RST transparency

2008-10-01T14:41:00Z

The TCP stack sends out SYN+ACK/ACK/RST reply packets in response to incoming packets. The non-local source address check on output bites us again, as replies for transparently redirected traffic won't have a chance to leave the node. This patch selectively sets the FLOWI_FLAG_ANYSRC flag when doing the route lookup for those replies. Transparent replies are enabled if the listening socket has the transparent socket flag set.

[PATCH] sysctl: make sure that /proc/sys/net/ipv4 appears before per-ns ones

2008-07-27T00:53:10Z

Massage ipv4 initialization - make sure that net.ipv4 appears as non-per-net-namespace before it shows up in per-net-namespace sysctls. That's the only change outside of sysctl.c needed to get sane ordering rules and data structures for sysctls (esp. for procfs side of that mess). Signed-off-by: Al Viro

mib: add net to NET_ADD_STATS_BH

2008-07-17T03:32:25Z

This one is tricky. The thing is that this macro is only used when killing tw buckets, but since this killer is promiscuous wrt to which net each particular tw belongs to, I have to use it only when NET_NS is off. When the net namespaces are on, I use the INET_INC_STATS_BH for each bucket. Signed-off-by: Pavel Emelyanov Signed-off-by: David S. Miller
