https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291273 Bug ID: 291273 Summary: p9fs module missing symbol exports -- dependent modules fail to load with module loader local symbol resolution disabled Product: Base System Version: 16.0-CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: emaste@freebsd.org Blocks: 207898 See https://lists.freebsd.org/archives/freebsd-current/2025-November/009500.html for background. To reproduce, set debug.link_elf_leak_locals=0 debug.link_elf_obj_leak_locals=0 then # kldload virtio_p9fs.ko link_elf_obj: symbol p9_init_zones undefined linker_load_file: /boot/kernel/virtio_p9fs.ko - unsupported file type kldload: an error occurred while loading module virtio_p9fs.ko. Please check dmesg(8) for more details. The module's Makefile should have an EXPORT_SYMS= line that lists all of the symbols to be intentionally exported. Another option is to just set EXPORT_SYMS=YES. An explicit export list is preferred over EXPORT_SYMS=YES, unless we actually want all symbols exported.
