Subject: Re: [XFRM] Call dst_check() with appropriate cookie
Date: Tue, 24 May 2005 17:26:37 +0900	[thread overview]
Message-ID: <4292E53D.7030805@miyazawa.org> (raw)

Hello,

Without our patch, the dst_check in xfrm_bundle_ok returns NULL
when it is IPv6 route, then xfrm_bundle_ok always fails.
xfrm_lookup calls xfrm_bundle_ok via stalbe_bundle so that
it goes to restart and recreate bundles.
But stale_bundle always fails. It results the infinite loop accordingly.

This bug only occurs on IPv6. IPv4 works correctly without the patch.

I can not show the evidence of the infinite loop
because the kernel freezes :-<
