Eric Dumazet fe42b170af net-tcp: fastopen: fix high order allocations
[ Upstream commit f5ddcbbb40 ]

This patch fixes two bugs in fastopen :

1) The tcp_sendmsg(...,  @size) argument was ignored.

   Code was relying on user not fooling the kernel with iovec mismatches

2) When MTU is about 64KB, tcp_send_syn_data() attempts order-5
allocations, which are likely to fail when memory gets fragmented.
