What You Will Do
- Analyze crashes, hangs and reboots related to live patching: oops and panic logs, vmcore with the crash tool, KASAN reports. Decide if the live patch caused it or not, and say so to the customer.
- Investigate problems during patching: apply failures, stuck transitions, unknown symbols, freeze conflicts with backup tools.
- Investigate missing patches and new kernel or distro support requests, and work with the patch team to add support.
- Answer deep CVE questions: check the patch sources, not only the docs.
- Find the root cause, give the patch team a clear report, and follow it to the fix.
- Be the named engineer for an enterprise customer during a Sev 1: their hosts are down, you own the case until it is closed.
- Help during big CVE events.
- On-call for Sev 1 with the team (24/7 is a contract obligation; we share it).
