From a1caa32295d67284ecba18cd8db692c7166f0706 Mon Sep 17 00:00:00 2001 From: Arnaud Ebalard Date: Mon, 3 Nov 2008 01:30:23 -0800 Subject: [PATCH] XFRM: copy_to_user_kmaddress() reports local address twice While adding support for MIGRATE/KMADDRESS in strongSwan (as specified in draft-ebalard-mext-pfkey-enhanced-migrate-00), Andreas Steffen noticed that XFRMA_KMADDRESS attribute passed to userland contains the local address twice (remote provides local address instead of remote one). This bug in copy_to_user_kmaddress() affects only key managers that use native XFRM interface (key managers that use PF_KEY are not affected). For the record, the bug was in the initial changeset I posted which added support for KMADDRESS (13c1d18931ebb5cf407cb348ef2cd6284d68902d 'xfrm: MIGRATE enhancements (draft-ebalard-mext-pfkey-enhanced-migrate)').
