>Description:
I am not able to load a kernel module (lkm or kmod) in NetBSD 5 RC3.
Note: Unless I am doing something terribly wrong here, this is an
important regression and should be hilighted in release notes if
it will remain in current state.
>How-To-Repeat:
# modload /usr/lkm/udf.o 2>&1 | head
/usr/lkm/udf.o: In function `udf_lkmentry':
: undefined reference to `lkm_nofunc'
/usr/lkm/udf.o: In function `udf_lkmentry':
: undefined reference to `lkm_nofunc'
/usr/lkm/udf.o: In function `udf_lkmentry':
: undefined reference to `lkmdispatch'
/usr/lkm/udf.o: In function `udf_lkmentry':
: undefined reference to `lkm_nofunc'
/usr/lkm/udf.o: In function `udf_lkmentry':
: undefined reference to `lkmdispatch'
# modload /stand/i386/5.0_RC3/modules/udf/udf.kmod
modload: module object must end in .o

State-Changed-Why:
i can reproduce this problem quite easily.
you can work around it by passing "-A /netbsd" (or your real kernel image)
to modload.
the difference is that /dev/ksyms has absolute symbols, and /netbsd has
data/text symbols, and ld(1) doesn't like that.
i tried applying this change from ad@ but it did not change the error:
Module Name: src
Committed By: ad
Date: Fri Dec 5 21:38:10 UTC 2008
Modified Files:
src/sys/kern: kern_ksyms.c
src/sys/sys: ksyms.h
Log Message:
Make the fake ELF object work with gdb.
- Output a .bss section and make all the symbols relative to it, instead
of making them absolute.
- Output a single load section, no need for two.
'gdb /dev/ksyms' still doesn't work because ksyms doesn't do mmap yet.

This is definitely fixed now.
