Hi
I have written a KLD module that implements a syscall
I wrote this module on 3.2-release, although this module is going to be
used on a 3.0-release machine
The relevant support for writing a syscall module was added after
3.0-release and is present in 3.1-release according to
http://www.FreeBSD.org/cgi/cvsweb.cgi/src/sys/sys/sysent.h.diff?r1=1.19&r2=1.20
Is it possible for me to hack my kernel module to work on freebsd
3.0-release? I
have tried patching the sys/sysent.h file with the patch linked above and
the module compiles perfectly, although when I kldload'd the module the
system crashed and rebooted. I didnt see the crash message, although I
can get that if it will help.
So my question is, is it possible for me to hack my kernel module to work
on FreeBSD 3.0-release? If not, can isolated patches be made to the
kernel short of doing a cvsup for src-all to enable this to work?
