Subject: ip_gre: fix ipgre_header to return correct offset MIME-Version: 1.0
From: =?UTF-8?q?Timo=20Ter=C3=A4s?= <[email protected]>
[ 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.")
