From: Greg Kroah-Hartman
Date: Tue Oct 10 2017 - 16:01:21 EST


4.13-stable review patch. If anyone has any objections, please let me know.

------------------

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>


[ Upstream commit 5829e62ac17a40ab08c1b905565604a4b5fa7af6 ]

All other error handling paths in this function go through the 'error'
label. This one should do the same.

Fixes: 9cc9a5cb176c ("datapath: Avoid using stack larger than 1024.")
