Hello and thanks for this bug report. The analysis looks sensible to me, but I'm not really familiar with gss. To better understand the situation I have a couple of questions:
- Does this mean that gss is unusable in Jammy at the moment? AFAICT this is the only bug report about it, so I would be surprised. - Are you able to test openssh from newer Ubuntu releases, ideally including Noble (the next LTS, currently in development)? The gss patch has been updated since Jammy, the last time on: Last-Updated: 2023-12-18 Thanks! ** Changed in: openssh (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/2053146 Title: openssh 8.9p1 for Jammy auth2-gss patch for gssapi-keyex method is slightly wrong Status in openssh package in Ubuntu: Incomplete Bug description: The Authmethod struct now have 4 entries but the initialization of the method_gsskeyex in the debian/patches/gssapi.patch only have 3 entries.
