Asymmetric crypto message on boot/dmesg

Hi all,

As someone that runs a TON of old junk in jails (including I believe a 4.11 somewhere), I've been seeing this message for ages:

"Deprecated code (to be removed in FreeBSD 14): Asymmetric crypto features via /dev/crypto"

This pops up during boot (jail startup) and also shows up in the dmesg buffer whenever I guess /dev/crypto is touched. A few questions:

- can we have this message state which jail (even jail ID) is generating the message?
- can the message include the PID of the process or really anything to identify what's triggering this?

I feel like this would be helpful for others with old software who are avoiding 14.x.

If not, what can I do with the system as it is to dig up what's generating this?

I'd like to see if this is something that can be upgraded, even for the jails trapped in CVE amber, or if I'm stuck moving these into vmware of bhyve.

Thanks,

Charles
