Subject: samba: build uses setresuid which doesn't work under 2.0.34 (does apparently under 2.2.x

Date: 2 Jul 1999 21:16:24 -0000

Package: samba
Version: 2.0.4b-3
Severity: grave

After installing this package and adding my user I get an error message in smb.log when I try to connect: 

[1999/07/02 10:48:22, 0] smbd/uid.c:become_gid(105)
  Couldn't set effective gid to 100 currently set to (real=0,eff=0)
[1999/07/02 10:48:22, 0] smbd/service.c:make_connection(425)
  Can't become connected user!

Searching the archives at the samba web site indicates that this is because the package was compiled to use the setresuid call (which apparently was introduced in the 2.1.x kernels). I compiled the package myself from the source package and this solved the problem so if this package was compiled on a 2.2.x system this is likely the problem.

Jens:

This has me puzzled: if I build the Samba packages in a Slink system
HAVE_SETRESUID is not set, but if I build in a Potato system it is
not. Obviously, the package I am uploading is the one built in the
Potato system. The strange thing is that both system are running
kernel 2.2.10 and I believe that in both cases the kernel headers used
for the build are from 2.2.x kernels (I will check that in a moment).

You are not the only one seeing this problem: another user running a
2.0.x kernel reported this today (although did not filed a bug
report).

There's something going on here but I don't know yet what it is. I'll
let you know what I find.

Thanks!

Hi!

I am very sorry for the delay in responding. I moved from Caracas,
Venezuela to Pittsburgh, USA last Wednesday and am working on the basic
stuff (apartment, bank accounts, Internet connectivity, furniture,
etc.). My last days have been very long and hectic and haven't had time
at all to work on Debian. This should change soon...

[HELP]

The problem seems to happen only if Samba was built on a system running
a 2.2.x kernel and glibc2.1 _and_ the binaries are run on a system that
uses a 2.0.x kernel.

If you run these binaries in the same environment they were built on
glibc2.1 and a 2.2.x kernel) everything is fine!

I would appreciate help from someone on this one.

This one is fixed already. samba-2.0.5a-2 is currently in Potato.

> Package: samba-common (main).

[FIX]
This one should be fixed as well with samba-common-2.0.5a-2.

I am closing in this same message the important and grave bugs that are
fixed already (I haven't had time to do so).

See ya!

Hallo Peloy,

this same bug has troubled me earlier this week.
Because there was no indication that it is related to the kernel version
I needed 2 hours to solve the puzzle.

I suggest you add a check in the {pre,post}inst script like

if [ "`uname -r |grep ^2.2`" == "" ]; then 
  echo please upgrade your kernel to 2.2.X
  echo or revert to the stable version.
  echo Press [enter]
  read
fi

TIA,

Jens

Finally, this is fixed in samba-2.0.5a-4. The patch was provided by Debian's
leader Wichert Akerman.

Cheers,

Thanks to a patch provided by our Debian's fearless leader (Wichert) this is
now solved and the same binaries can be used with both 2.0.x and 2.2.x
kernels.

Sorry it took so long.
