1) Does the kernel have COMPAT_DF12 or COMPAT_43 defined?
2) Can you check if the kernel has the sys_osethostname symbol? (nm /boot/kernel/kernel | grep sys_osethostname)

Could someone also look at a GENERIC kernel and check if /usr/obj/<whatever>/opt_compat.h defines COMPAT_43 to '1' even if COMPAT_43 is not set in GENERIC? It looks like that is the case here, which is a problem, as it turns on awful gorp.

Adding 'options COMPAT_43' to kernel config solves problem.
(I also found that myself, but thanks a lot for looking into this)

COMPAT_43 was removed from GENERIC recently (2nd Novemer 2011);
but it seems like linux kernel module needs it for now,
I will readd COMPAT_43 to GENERIC.

After fixing this I got another linux emulation problem:
mount_linprocfs panic'ed, I have opened issue 2290 for this.

Venkatesh,

See below for answer for your questions.

-
$ head -99 `find /usr/obj/usr/src/sys/GENERIC -name opt_compat.h`
> /usr/obj/usr/src/sys/GENERIC/usr/src/sys/dev/serial/digi/opt_compat.h <
#define COMPAT_43 1

This isn't a good fix. Can we do something like this:
http://evilprojects.net/dragonflybsd/0001-linux-Add-native-sethostname-implementation.patch
(untested)
instead?

Thanks.

----------------------------------------
Bug #2289: 'kldload linux' fails
http://bugs.dragonflybsd.org/issues/2289

Author: Thomas Nikolajsen
Status: New
Priority: Normal

Target version:

On master and DragonFly_RELEASE_3_0 from yesterday (25th January 2012)
loading linux.ko kernel module fails,
both using loader(8) and kldload(8):
link_elf: symbol sys_osethostname undefined.
(i.e. both binutils 2.22 and 2.21)

This may be binutils related;
I think it worked with binutils 2.17, will test.

This is using a custom kernel; will test GENERIC.

1. kldload linux
   link_elf: symbol sys_osethostname undefined
   kldload: can't load linux: No such file or directory

Here's a fixed version of that patch:

http://apollo.backplane.com/DFlyMisc/linux01.patch

It fixes several issues with Sam's sethostname transplant and also
    fixes linux_ostat (which also needed a transplant).

Thanks for patches; I will test and commit later today.
Just adding COMPAT_43 was quick & dirty work around :)

We would like to have COMPAT_DF12 enabled, but not COMPAT_43; is it clear why COMPAT_43 is being pulled in when only _DF12 is set in GENERIC?

Patch committed to master & rel3_0 (b4d6d1 & 2aeaf5);
hack in linux/Makefile which did set COMPAT_43 is also removed.
