It uses malloc'd per-op buffer. While concurrent operations on a session are probably rare, we don't do anything to prevent = them currently and this makes them safe. I also prefer to not muddy the per-ses= sion state with per-op state. The relevant commits are: https://github.com/freebsd/freebsd/commit/6d93ba89e16b137cca55b377c46430815= cb68464 along with 3 followup fixes in this branch: https://github.com/freebsd/freebsd/compare/master...bsdjhb:openssl_engine I don't have an ETA for when this might reach HEAD apart from "soon-ish". I have some other open reviews for /dev/crypto changes that I haven't been ab= le to get any review for already. --=20 You are receiving this mail because: You are the assignee for the bug.=
