So indeed there was likely a temporary problem when doing the signing

I checked as well linux-signed-i386 and linux-signed-arm64 but there I
found none with a problem.

Ansgar, assuming at this point we cannot do something anymore for the
point release.

Cyril, Adam, so skip the kernel update for the upcoming point release?

The alternative would be given that the "only" two modules affected
are watchdog and w83977f_wdt to proceed as planned with the point
release (testing, Cyril?) and make a nearby src:linux DSA release
including further security fixes.

6.14.7, 6.12.29 and 6.1.139 are currently beeing reviewed upstream in particular including the ITS variant of the "Training Solo" issue
(side note, to be effective the fixes will need as well a
intel-microcode update, cf. #1105172).

Hola,

We discussed briefly just now and decided that:

- as it's "just" amd64 watchdog and w83977f_wdt modules, and
- a kernel DSA is imminent anyway, and
- deferring the point release and skipping the kernel are both major
upheavals,

we intend to continue as planned and include a warning in the announcement
on release, that affected users should disable their watchdogs or not
reboot until an updated kernel is released very soon after the point
release will be.

If there are other issues we have not considered please speak up urgently.

Hi,

Jonathan Wiltshire <[email protected]> (2025-05-12):

We discussed briefly just now and decided that:

- as it's "just" amd64 watchdog and w83977f_wdt modules, and

It's been a while since I last toyed with watchdogs (and those needed
explicit actions to be enabled anyway), but I'd expect those not to be
shipped or used within d-i, so probable ACK on the installer front.

A quick look through Contents-udeb-* through a reconfigured apt-file
seems to suggest they're not shipped in any udeb. Definitive ACK then.

- a kernel DSA is imminent anyway, and
- deferring the point release and skipping the kernel are both major
upheavals,

we intend to continue as planned and include a warning in the
announcement on release, that affected users should disable their
watchdogs or not reboot until an updated kernel is released very soon
after the point release will be.

If there are other issues we have not considered please speak up
urgently.

Unless you tell me otherwise I'll stick to testing then uploading d-i
with the ABI bumped to 35. (And it can still be rejected from pu-NEW
anyway?)


Cheers,
