Hi Release team,
I would appreciate your pre-approval for the following stable-update.
[ Reason ]
tayga=0.9.2-10 in Trixie regressed in the handling of 'map' directives:
#1082060.
[ Impact ]
This breaks one of the core features of tayga, the ability to establish a
mapping between individual IPv4 and IPv6 addressess. Most importantly this
impacts the 464XLAT CLAT use-case (see the clatd=2.1.0-2+deb13u1 p-u).
[ Tests ]
I've manually validated the fix and confirmed map directives as generated
by clatd work with the "Fix EAM mapping for host addressess" patch.
The patch was taken from a new upstream fork of tayga by Andrew "apalrd"
which has added very rigorous automated tests using scapy and I've reviewed
Andrew's commit history since he forked our 0.9.2-10 and manually confirmed
that no other relevant change was made to the translation code as part of
this concentrated testing effort.
[ Risks ]
The calc_ip4_mask() function we touch here is used throughout the
code. Complex configurations could have interactions we don't expect.
We could de-risk this further by digging into the details of why the
changes to our EAM support patch as part of -9 broke this feature, but I
don't think it necessary given the deep testing Andrew did to arrive at
this single-line change.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in (old)stable
[ ] the issue is verified as fixed in unstable -- No: upload in NEW
[ Changes ]
- Add a patch "Fix EAM mapping for host addressess" which adds a special
case for the ipv4 mask calculation with /32 (host) addressess.
Thanks,
--Daniel
