[PATCH 3.14 01/39] xfrm: Fix installation of AH IPsec SAs
From: Greg Kroah-Hartman
Date: Fri Aug 08 2014 - 18:02:29 EST
3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tobias Brunner <tobias@xxxxxxxxxxxxxx>
[ Upstream commit a0e5ef53aac8e5049f9344857d8ec5237d31e58b ]
The SPI check introduced in ea9884b3acf3311c8a11db67bfab21773f6f82ba
was intended for IPComp SAs but actually prevented AH SAs from getting
installed (depending on the SPI).
Fixes: ea9884b3acf3 ("xfrm: check user specified spi for IPComp")
