I just tested a feature specific to HardenedBSD: force calls to malloc(9) to include the M_ZERO flag (the hardening.kmalloc_zero sysctl tunable.) I have that tunable set to 1 in loader.conf(5) on both laptops. It appears this commit conflicts with the feature in general. I'll see what I can do on HardenedBSD's side to better align our feature with this commit. Sorry for the noise. For reference, here are the two HardenedBSD commits that provide the feature: 1. https://git.hardenedbsd.org/hardenedbsd/HardenedBSD/-/commit/c3ee4601417ae1= daa7a0a3adc9259bf0739a8d55 2. https://git.hardenedbsd.org/hardenedbsd/HardenedBSD/-/commit/5283e229590401= fe389f4ca46c4071a48032d46a Thanks, --=20 Shawn Webb Cofounder / Security Engineer HardenedBSD Tor-ified Signal: +1 303-901-1600 / shawn_webb_opsec.50 https://git.hardenedbsd.org/hardenedbsd/pubkeys/-/raw/master/Shawn_Webb/03A= 4CBEBB82EA5A67D9F3853FF2E67A277F8E1FA.pub.asc --auvisgfq4a56ngvr Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEA6TL67gupaZ9nzhT/y5nonf44foFAma5EVsACgkQ/y5nonf4 4foQQg//b7oi/Elh4DTnpnZnTGKUqy9WLCtEVFqJB8lTn6GJhZqhxTd5fbH5gQPz 9qwwiiFY5J3sf8BhIH6PQmnoo07634p76f4vu2RB1KLAPDTDHKd55iEP1IbvtilL S7e6+ZHmUDIDsbl3hhcLjF1ybfCpgjB+9U8gskHEwDlKECOxsEnVLlGRyZmKjeEj 5Wtd7VlyJHyqWGgzZYN7IaOEdysWhY+C/QXF1Wmz1iZNL81hrfqoZHuEWy+Z/DGi C4l2Mm18ZFxNQk0oPQzK4WyBiEGUywciu2XWNN4VyOOsYNrlnRfuie/EsRLx8qEr 50wor1BlqZ7H8IO+6JkE5Bd/R3yQGc62i06xAEUzKviaPzHVS8MQlm/sgvey9KLd aVOArPqpctCofPaKrEf1N3tLdK0mps5ksVlDvbOHY3X6wtXdhhpUA2Sdok6IaI6Y iqPwp74JwOGwkvr01cJ+v4zevrE6uik3jTORXq98so92FN6ZxtKuHfDYW614qS9i tsaJPGSfG5lpRh8WGY/umzA9B+r7pT33V9hbePVE5wcC0XvbSKwS3w5EaCz6D/tO ybeht4Anj8OL1yc0+hBrTUJ7hosYFcQeztaCsoTKkMuxxNG6Fe1PgbPeIqB1vIWO LDUk+aw20hKeWQPFiRhKC37izH6bL0Rq5q4mRifHlsLApGe6gH0= =rbOq -----END PGP SIGNATURE----- --auvisgfq4a56ngvr--
