From 7b4dc3600e4877178ba94c7fbf7e520421378aa6 Mon Sep 17 00:00:00 2001 From: Masahide NAKAMURA Date: Wed, 27 Sep 2006 22:21:52 -0700 Subject: [PATCH] [XFRM]: Do not add a state whose SPI is zero to the SPI hash. SPI=0 is used for acquired IPsec SA and MIPv6 RO state. Such state should not be added to the SPI hash because we do not care about it on deleting path.
