Subject: [PATCH v2 0/3] x86: CET-SS related adjustments
Date: Wed, 8 Apr 2026 14:20:29 +0200 [thread overview]
Message-ID: <f064c3af-c22a-40e0-a268-ee37e34297a3@suse.com> (raw)
One might think of this as follow-on to XSA-451, but that's not quite
the right order of events.
There are a few open aspects; see individual patches.
v2, besides addressing small issues, is mainly a re-base over FRED
work finally having gone in.
1: record SSP at non-guest entry points
2: traps: use entry_ssp in fixup_exception_return()
3: prefer shadow stack for producing call traces
