net: Use a percpu_counter for orphan_count · dd24c001

由 Eric Dumazet 提交于 11月 25, 2008

Instead of using one atomic_t per protocol, use a percpu_counter
for "orphan_count", to reduce cache line contention on
heavy duty network servers.

Instead of using one atomic_t per protocol, use a percpu_counter
for "sockets_allocated", to reduce cache line contention on
heavy duty network servers. 

Note : We revert commit (248969ae

tc: policing requires a rate estimator · c1b56878

由 Stephen Hemminger 提交于 11月 25, 2008

Found that while trying average rate policing, it was possible to
request average rate policing without a rate estimator. This results
in no policing which is harmless but incorrect.

Since policing could be setup in two steps, need to check
in the kernel.

netns xfrm: per-netns sysctls · b27aeadb

由 Alexey Dobriyan 提交于 11月 25, 2008

Make

	net.core.xfrm_acq_expires
	net.core.xfrm_aevent_rseqth
	net.core.xfrm_larval_drop

sysctls per-netns.

For that make net_core_path[] global, register it to prevent two
/proc/net/core antries and change initcall position -- xfrm_init() is called
from fs_initcall, so this one should be fs_initcall at least.
