From de248a75c35e0208294cf304b112916254b69184 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 25 Apr 2012 23:43:04 +0000 Subject: tcp repair: Fix unaligned access when repairing options (v2) Don't pick __u8/__u16 values directly from raw pointers, but instead use an array of structures of code:value pairs. This is OK, since the buffer we take options from is not an skb memory, but a user-to-kernel one. For those options which don't require any value now, require this to be zero (for potential future extension of this API). v2: Changed tcp_repair_opt to use two __u32-s as spotted by David Laight.
