From f5ddcbbb40aa0ba7fbfe22355d287603dbeeaaac Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 20 Feb 2014 10:09:18 -0800 Subject: [PATCH] net-tcp: fastopen: fix high order allocations 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.
