3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: =?UTF-8?q?Timo=20Ter=C3=A4s?= <timo.teras@xxxxxx> [ Upstream commit 77a482bdb2e68d13fae87541b341905ba70d572b ] Fix ipgre_header() (header_ops->create) to return the correct amount of bytes pushed. Most callers of dev_hard_header() seem to care only if it was success, but af_packet.c uses it as offset to the skb to copy from userspace only once. In practice this fixes packet socket sendto()/sendmsg() to gre tunnels. Regression introduced in c54419321455631079c7d6e60bc732dd0c5914c5 ("GRE: Refactor GRE tunneling code.")
