Problem description:

Could not get racoon to work properly. 

When using IPSec without labels, the kernel sends and ACQUIRE message that
contains a security context. This security context contains garbage. When labels
are not being used, then the kernel should send an ACQUIRE without a security

Upon looking at code, when we allocate a policy, we never initialize the
security structure in the policy. Thus it is possible for it to contain garbage.
Probably should initialize to zero or null. 

I am using a rawhide kernel, vmlinuz-2.6.17-1.2617.2.1.fc6.

Hardware Environment
    Machine type - lpar 
    Cpu type - Power5

Will add patch to this bug report as soon as I create it.

Please mirror this bug report to RedHat and to Issue Tracker.
I would also like iboverma@redhat.com and sgrubb@redhat.com be added to the CC

I'm not sure this was mirrored correctly; I think the Issue Tracker numbers 
start with "RIT".

My understanding is that we mirror with Issue Tracker for the RHEL products
and use Red Hat Bugzilla for Fedora or testing unreleased versions.

OK - I was thinking she was using the beta, but now I see she said rawhide.

I have compiled and tested this patch against rawhide kernel,
I have also compiled against, linux-2.6.17+patch-2.6.18-rc7+2.6.18-rc7-mm1
and will post to netdev@vger.kernel.org for upstream acceptance.

The bug was not in the kernel code, but in the racoon utility.
The racoon utility is the IKE daemon used to configure SAs in IPSec.
I have integrated the fix for this into the racoon patch which was posted 
today on redhat-lspp mailing list.
