The branch main has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=4b0ae7e001a97e5449835bb8a2e6c2e6f53aac39 commit 4b0ae7e001a97e5449835bb8a2e6c2e6f53aac39 Author: Mark Johnston <markj@FreeBSD.org> AuthorDate: 2026-07-15 14:58:32 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2026-07-15 14:58:32 +0000 stand: Recognize SHT_INIT_ARRAY sections as constructor sections Pass such a section to the kernel using modinfo, otherwise link_elf.c won't execute constructors for the file. This is required for KASAN, otherwise redzones for global buffers are not poisoned during boot.
