!== DNIX.txt for Samba release 2.2.0-alpha3 24 Mar 2001
!==
DNIX has a problem with seteuid() and setegid(). These routines are
needed for Samba to work correctly, but they were left out of the DNIX
C library for some reason.
For this reason Samba by default defines the macro NO_EID in the DNIX
section of includes.h. This works around the problem in a limited way,
but it is far from ideal, some things still won't work right.
To fix the problem properly you need to assemble the following two
functions and then either add them to your C library or link them into
Samba.
put this in the file setegid.s:
.globl _setegid
_setegid:
moveq #47,d0
movl #100,a0
moveq #1,d1
movl 4(sp),a1
trap #9
bccs 1$
jmp cerror
1$:
clrl d0
rts
put this in the file seteuid.s:
.globl _seteuid
_seteuid:
moveq #47,d0
movl #100,a0
moveq #0,d1
movl 4(sp),a1
trap #9
bccs 1$
jmp cerror
1$:
clrl d0
rts
after creating the above files you then assemble them using
as seteuid.s
as setegid.s
that should produce the files seteuid.o and setegid.o
then you need to add these to the LIBSM line in the DNIX section of
the Samba Makefile. Your LIBSM line will then look something like this:
LIBSM = setegid.o seteuid.o -ln
You should then remove the line:
#define NO_EID
from the DNIX section of includes.h
Then recompile and try it out!
Note that this file was derived from an email from Peter Olsson
<pol@leissner.se>. I don't have DNIX myself, so you're probably better
off contacting Peter if you have problems.
