Subject: [PATCH bpf-next v2 0/3] keys: Add well known IDs for fs-verity/dm-verity keys
Date: Thu, 08 Oct 2026 15:57:34 -0500 [thread overview]
Message-ID: <20261008-ajhalaney-dmverity-key-identifier-v2-0-008456d189cb@amutable.com> (raw)
This more or less follows the bpf keyring approach, allowing userspace
to easily find the keys instead of having to parse /proc/keys.
Signed-off-by: Andrew Halaney <andrew@amutable.com>
---
Changes in v2:
- Rebased / target bpf-next/for-next since 264d8fd2794f ("bpf, keys: Add a bpf
keyring for program signature validation") only exists there.
- Grabbed Reviewed-by trailers.
- Link to v1: https://lore.kernel.org/r/20260914-ajhalaney-dmverity-key-identifier-v1-0-01922dc1366a@amutable.com
