Merge branch 'tcp-listener-fixes-and-improvement'
Eric Dumazet says:
====================
tcp: lockless listener fixes and improvement
This fixes issues with TCP FastOpen vs lockless listeners,
and SYNACK being attached to request sockets.
Then, last patch brings performance improvement for
syncookies generation and validation.
Tested under a 4.3 Mpps SYNFLOOD attack, new perf profile looks
like :
12.11% [kernel] [k] sha_transform
5.83% [kernel] [k] tcp_conn_request
4.59% [kernel] [k] __inet_lookup_listener
4.11% [kernel] [k] ipt_do_table
3.91% [kernel] [k] tcp_make_synack
3.05% [kernel] [k] fib_table_lookup
2.74% [kernel] [k] sock_wfree
2.66% [kernel] [k] memcpy_erms
2.12% [kernel] [k] tcp_v4_rcv
