Came across this today (and is reproducable): With COMPAT_IA32 removed from the kernel configuration, accf_http.ko breaks in a bad way. Only shown on the console is the message "kldload: Unsupported file type" when kldload is used to load the module. Worse, the module linker appears to load a portion of the module anyways: # kldstat Id Refs Address Size Name 1 2 0xffffffff80100000 566cd0 kernel 2 1 0xffffffffb468a000 795 accf_http.ko # kldstat -v -i 2 Id Refs Address Size Name 2 1 0xffffffffb468a000 795 accf_http.ko Contains modules: Id Name 173 accf_http And attempts to unload the module fail (which is where I question the reliability of the module linker (no offence intended)): # kldunload accf_http.ko kldunload: can't unload file: Operation not supported icarus# kldunload -v -f accf_http.ko Unloading accf_http.ko, id=2 kldunload: can't unload file: Operation not supported Minor details: -r-xr-xr-x 1 root wheel 5544 Jul 3 10:35 /boot/kernel/accf_http.ko /boot/kernel/accf_http.ko: ELF 64-bit LSB relocatable, AMD x86-64, version 1 (FreeBSD), not stripped Putting COMPAT_IA32 back in results in proper behaviour all around. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
