2009-04-17[PATCH] net: remove superfluous call to synchronize_net()Eric Dumazet
inet_register_protosw() function is responsible for adding a new inet protocol into a global table (inetsw[]) that is used with RCU rules. As soon as the store of the pointer is done, other cpus might see this new protocol in inetsw[], so we have to make sure new protocol is ready for use. All pending memory updates should thus be committed to memory before setting the pointer. This is correctly done using rcu_assign_pointer() synchronize_net() is typically used at unregister time, after unsetting the pointer, to make sure no other cpu is still using the object we want to dismantle. Using it at register time is only adding an artificial delay that could hide a real bug, and this bug could popup if/when synchronize_rcu() can proceed faster than now. This saves about 13 ms on boot time on a HZ=1000 8 cpus machine ;) (4 calls to inet_register_protosw(), and about 3200 us per call) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2009-04-16myri10ge: force stats update in ethtool gstatsBrice Goglin
Force a statistics update when our ethtool gstats routine is called. Otherwise, ethtool will continue to read stale stats until something forces an update by reading /proc/net/dev This requires putting a lock around the stats update to guard against 2 threads (one via ethtool, and one via procfs) updating the stats at once.

2009-04-16netfilter: nf_nat: add support for persistent mappingsPatrick McHardy
The removal of the SAME target accidentally removed one feature that is not available from the normal NAT targets so far, having multi-range mappings that use the same mapping for each connection from a single client. The current behaviour is to choose the address from the range based on source and destination IP, which breaks when communicating with sites having multiple addresses that require all connections to originate from the same IP address. Introduce a IP_NAT_RANGE_PERSISTENT option that controls whether the destination address is taken into account for selecting addresses. http://bugzilla.kernel.org/show_bug.cgi?id=12954 Signed-off-by: Patrick McHardy <kaber@trash.net>
