SCMP errors received.Replaced by lib/snet: expose metrics #3107, for now. Eventually it would be nice to know what actions got an scmp error reply. - Crypto issues:
- cert/trc request failures: timeouts vs not available
- Signature verification failed (e.g. possible forgery)
- Signature validation failed (e.g. signature from expired cert)
-
