As a disclaimer, I would like to clarify that Gentoo/FreeBSD uses a FreeBSD userland and that Gentoo/FreeBSD has nothing to do with Debian GNU/kFreeBSD. People seem to think Gentoo/FreeBSD is related to Debian GNU/kFreeBSD, which has made collaboration difficult.
With that said, Gentoo Portage is warning about text relocations in kernel modules. This is in a Gentoo/FreeBSD port of emulators/freebsd-kmod that I wrote. For instance, I see: # readelf -d /boot/modules/virtio.ko Dynamic section at offset 0x2f6c contains 13 entries: Tag Type Name/Value 0x00000004 (HASH) 0xd4 0x6ffffef5 (GNU_HASH) 0x238 0x00000005 (STRTAB) 0x4a8 0x00000006 (SYMTAB) 0x298 0x0000000a (STRSZ) 397 (bytes) 0x0000000b (SYMENT) 16 (bytes) 0x00000011 (REL) 0x638 0x00000012 (RELSZ) 1568 (bytes) 0x00000013 (RELENT) 8 (bytes) 0x00000016 (TEXTREL) 0x0 0x0000001e (FLAGS) TEXTREL 0x6ffffffa (RELCOUNT) 108 0x00000000 (NULL) 0x0 Checking /boot/kernel, it seems that all modules have text relocations. My Gentoo/FreeBSD install is a 32-bit chroot on a ZFS Guru install of amd64 FreeBSD. amd64 FreeBSD does not appear to have any text relocations. I don't have a reference i386 install, but according to frogs in ##freebsd on freenode, his i386 FreeBSD also has text relocations. Is this a bug?
