net-tcp: fastopen: fix high order allocations
[ Upstream commit f5ddcbbb40aa0ba7fbfe22355d287603dbeeaaac ]
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.
Fixes: 783237e8daf13 ("net-tcp: Fast Open client - sending SYN-data")
