This patch series makes changes to TCP/DCCP stacks so that
we can switch listener code to lockless mode.
This is done by marking const the listener socket in all
appropriate paths.
FastOpen code had to be changed to not dynamically allocate
a very small structure to make code simpler for following changes.
Eric Dumazet (14):
tcp/dccp: constify send_synack and send_reset socket argument
tcp: remove unused len argument from tcp_rcv_state_process()
tcp: remove tcp_rcv_state_process() tcp_hdr argument
dccp: use inet6_csk_route_req() helper
inet: constify inet_csk_route_child_sock() socket argument
inet: constify __inet_inherit_port() sock argument
net: constify sk_gfp_atomic() sock argument
dccp: constify dccp_create_openreq_child() sock argument
tcp: constify tcp_create_openreq_child() socket argument
tcp/dccp: constify syn_recv_sock() method sock argument
tcp: cookie_init_sequence() cleanups
tcp: constify tcp_v{4|6}_route_req() sock argument
tcp: constify tcp_syn_flood_action() socket argument
tcp: prepare fastopen code for upcoming listener changes
