--gv4zn2hvd2gk4pez Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hey all, It looks like there's a potential deadlock in some networking code, specifically with ipv4 jails. I can reproduce by running Poudriere on 14-CURRENT. I am using HardenedBSD 14-CURRENT, but we don't have any changes to any point in the code paths that would trigger/cause this kind of kernel panic. I've uploaded the crash.txt file here: https://hardenedbsd.org/~shawn/2021-12-09_crash-01.txt `uname -a`: FreeBSD ci-08 14.0-CURRENT-HBSD FreeBSD 14.0-CURRENT-HBSD #0 h= ardened/current/master-n191216-7474f245a83: Wed Dec 8 22:44:04 EST 2021 = shawn@ci-08:/usr/obj/usr/src/amd64.amd64/sys/HARDENEDBSD amd64 Thanks, --=20 Shawn Webb Cofounder / Security Engineer HardenedBSD https://git.hardenedbsd.org/hardenedbsd/pubkeys/-/raw/master/Shawn_Webb/03A= 4CBEBB82EA5A67D9F3853FF2E67A277F8E1FA.pub.asc --gv4zn2hvd2gk4pez Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEA6TL67gupaZ9nzhT/y5nonf44foFAmGyHqcACgkQ/y5nonf4 4fp6Lw/+OghEgXfpQ14+Cyst2LvmXIkK2lLmN1Tx6+SHOwn0MWarP6SAX4v//Aez I6A7iGDjaQwc6UrXtGMv20fIqVA94p1x6afEwgPE1LZvFKxt9bQTz9rhFTSX1Ikd BPUepnLw7YRbPizfC9omu/IHGfAfx3lGGdsilLxlZixiksaRi8zwb+v5BWN3px7a 4ChMkXiUDBI/GVOvcvzcbnUdk++54rsT+7nbpT3VNBJVRQfi8TxH7B/Fuebc6n4k 7kPvwImBY5Vk0R5Nks2WEOLwDv1TmqW5SozDb21wCSJo8Nb0LCirkciudoYJEwqY JG3vVo7CPa46oxJ4JgLITbuEC6jcr/LjCUJpBIUHRJrPyzapKk1LIE+5S0JtMx3G z8/rIrqSE/Qd6HbK7mfA03oeilcQMPeoYlX/CrcuADNPGnRaOfSs+9OrS5p96iDq 6TI35qjjxyoGo4eUW0Ln2kN0L7bDzkBUPstRogb3kC0kXpel5zAotqqStAyRcz0n PQfvzPQwM9Dxd+7tA7+Zlm743s6zcpFMXGT1suNiXLYlarGYrUKU12w/O0NC/JGJ eJ6wmSVgq2tVLsgR53mRfr2PyQcZXfpVAhEPnGuNVJPCe2sqNizde/Ttzks3bVwO RZ9tU+5SUMe72+fJjpb6JwdoSrcUF1tLVM25PNvl9eAElm+26I0= =lujs -----END PGP SIGNATURE----- --gv4zn2hvd2gk4pez--
