Merge branch 'tcp-udp-misc'
Eric Dumazet says:
====================
net: various udp/tcp changes
First round of patches for linux-4.7
Add a generic facility for sockets to be freed after an RCU grace
period, if they need to.
Then UDP stack is changed to no longer use SLAB_DESTROY_BY_RCU,
in order to speedup rx processing for traffic encapsulated in UDP.
It gives a 17 % speedup for normal UDP reception in stress conditions.
Then TCP listeners are changed to use SOCK_RCU_FREE as well
to avoid touching sk_refcnt in synflood case :
I got up to 30 % performance increase for a mono listener.
Then three patches add SK_MEMINFO_DROPS to sock_diag
and add per socket rx drops accounting to TCP.
Last patch adds rate limiting on ACK sent on behalf of SYN_RECV
to better resist to SYNFLOOD targeting one or few flows.
