HardenedBSD August 2024 Status Report

This month was focused on ${LIFE} for me. One of our two dogs, Darth Vader, had a planned surgery that ended up being more intensive than originally anticipated. Just today (03 Sep 2024), he got a good bill of health from the veterinarian. He still can't use our doggy door to the backyard, but is a healthy good boy otherwise. :-) We launched our first Signal group for the HardenedBSD community. FreeBSD implemented a mechnism to prohibit local connections to wildcard addresses (like 0.0.0.0 or ::0). With commit 8624aac8cefa38382a1ae3f40b604581bc4cf69f, we now enable the prohibition by default. Commit d2d91bf7ba3eaf7bda029f3004553c6b45b90fe4 causes certain syscalls to have in-kernel dynamic data structures zeroed by default. FreeBSD recently made changes to the in-kernel heap implementation (see malloc(9)). Those changes are incompatible with our hardening.kmalloc_zero feature. I have not had ample time to address this incompatibility, but hope to soon. As such, users who run 15-CURRENT and have set hardening.kmalloc_zero=1 should temporarily disable the feature prior to upgrading to the 01 Sep 2024 build. In ports: net-p2p/heartwood and related ports have been updated to 1.0.0-rc16. A fix for _FORTIFY_SOURCE support has been pulled in for devel/libudev-devd. 0x1eef updated hardenedbsd/sourcezap to v1.0.0. 0x1eef updated hardenedbsd/portzap to v1.0.0. A new (currently untested) build of hbsdfw has been published and can be found here.

All contributions, no matter the form in which they take, are immensely appreciated. Patches, advocacy, funding, or otherwise--it's all important and helpful.\...
