I use mock to build packages for old distributions in a chroot-ed
environment on my FC5 box. I've pretty well got this working for all old
distributions now apart from FC2 (see
http://www.fedoraproject.org/wiki/Legacy/Mock). On FC2, the process gets
off to quite a good start, installing the following packages into the
chroot:

In fc2 you should disable SELinux.

In fc2 you should disable SELinux.
I'm running this on FC5; what I'm trying to do is set up a chroot with
FC2 packages. This includes the FC2 version of useradd, and it's this
that's hanging when run in the chroot.
I'd happily give things in the chroot the impression that SELinux is
disabled (I believe mock actually does this already) but I *really*
don't want to disable SELinux on my FC5 host.

I'm running this on FC5; what I'm trying to do is set up a chroot with
FC2 packages. This includes the FC2 version of useradd, and it's this
that's hanging when run in the chroot.
I'd happily give things in the chroot the impression that SELinux is
disabled (I believe mock actually does this already) but I *really*
don't want to disable SELinux on my FC5 host.
Paul.
I have no idea why this would happen then.
And I am not sure I believe them when they say that if SELinux was
disabled this would work differently, unless there is a kernel bug. You
are not seeing avc messages, correct? Usually if it does not work in
permissive mode it is not an SELinux problem.

I guess I'll have to bite the bullet and try it with SELinux disabled

people that have this working with SELinux disabled, and I vaguely
recall it working for me when I was first trying this (with SELinux
disabled, probably a year ago). I've got it working for everything from
RHL7 through to FC5 targets apart from FC2, so I doubt I'm doing
something significantly wrong.

*Usually*...
I guess I'll have to bite the bullet and try it with SELinux disabled
(so I'll have to relabel my desktop box afterwards, sigh). I know of two
people that have this working with SELinux disabled, and I vaguely
recall it working for me when I was first trying this (with SELinux
disabled, probably a year ago). I've got it working for everything from
RHL7 through to FC5 targets apart from FC2, so I doubt I'm doing
something significantly wrong.
I've now got a nice shiny new x86_64 box so at last I've been able to
sacrifice my old build system by disabling SELinux on it. My
recollection was correct - the mock build for FC2 worked just fine with
SELinux disabled.
Any thoughts on what might be going on here?
Paul.

I've now got a nice shiny new x86_64 box so at last I've been able to
sacrifice my old build system by disabling SELinux on it. My
recollection was correct - the mock build for FC2 worked just fine with
SELinux disabled.
Any thoughts on what might be going on here?
Did you ever try stracing the useradd process to see what it is doing at
the point where it hangs?

Did you ever try stracing the useradd process to see what it is doing at
the point where it hangs?
It's a bit fiddly to do this for mock because it runs all "root"
commands through an SUID helper that checks what it's running. However,
by adding the following line to the FC2 mock config line, I think I may
have turned something up:
config_opts['chroot'] = '/usr/bin/strace /usr/sbin/mock-helper chroot'
With this set, the build actually seems to get further than the
"useradd", though the "useradd" does in fact fail because the chroot
is
refused:

So, any thoughts on why the "Operation not permitted" for the chroot
would happen? Is this to do with running under strace, or is it the
underlying issue?
All "chroot" calls seem to have failed in the trace.
Without the strace, I know the "/builddir" directory (which is to be the
home directory of the added user) isn't created, so I suspect that
running under strace isn't the problem in itself.

Actually I have to take this back. Using the same mock hack for FC3
causes a fail in exactly the same way, with all chroot() calls failing.
I think I'll need to hack at the mock-helper code to allow that to
invoke strace rather than running the mock-helper under strace itself.
Or is that likely to fail in the same way?

Did you ever try stracing the useradd process to see what it is doing at
the point where it hangs?
Aha. Now we're getting somewhere:

Any suggestions on how I get past this request to enter a security
context, or better still, have it not ask?
Paul.
Remove multiple from pam_selinux line in /etc/pam.d/su or better yet use
runuser.

Remove multiple from pam_selinux line in /etc/pam.d/su or better yet use
runuser.
FC2 doesn't have runuser, which is why we need to use su here.
I should be able to fix /etc/pam.d/su by patching the FC2 coreutils
package to remove the "multiple"; what's that actually do?
Mock includes a dummy libselinux that works for FC3 onwards in
convincing programs running in the chroot that selinux is disabled:
#include <selinux/selinux.h>
extern int is_selinux_enabled(void)
{
/* always return 0; this way we don't trigger any SELINUX calls */
return 0;
}
/* this function gives failures when installing basic rpms in the root;
* so we fake it out as well */
extern int lsetfilecon(const char *path, security_context_t con)
{
return 0;
}
Why does this not seem to be working for FC2?
Paul.

FC2 doesn't have runuser, which is why we need to use su here.
I should be able to fix /etc/pam.d/su by patching the FC2 coreutils
package to remove the "multiple"; what's that actually do?
This didn't work. Fails in exactly the same way as before.
I do see attempted reads of the non-existent files:
/selinux/access
/selinux/enforce
/selinux/user
/etc/security/failsafe_context
and I see a read of /proc/self/attr/current returning
user_u:system_r:mock_t:s0, which clearly isn't going to be appropriate
for a process running in an FC2 chroot.
Supposing I just remove the pam_selinux from /etc/pam.d/su altogether?
Is that likely to break anything? Any other way of persuading an FC2
system that SELinux is disabled?

Removing it should be fine (and has already happened in FC5). I'm not
clear on the cause though - pam_selinux returns immediately with
PAM_SUCCESS if is_selinux_enabled() returns <= 0.

PAM_SUCCESS if is_selinux_enabled() returns <= 0.
It got further with that line removed, and now hangs when trying to run
rpm as the user "mockbuild" that was added by "useradd". This appears
to
be the first chroot command that's not running as root. It's not obvious
to me what it's waiting for.
Mock root log, with straces of all chroot commands attached.

It got further with that line removed, and now hangs when trying to run
rpm as the user "mockbuild" that was added by "useradd". This appears
to
be the first chroot command that's not running as root. It's not obvious
to me what it's waiting for.
It turns out it must have been waiting for a password, because after
killing the process the echo on the terminal was turned off.
I now believe I have solved this problem. Many, many thanks to Dan and
Stephen for helping.
The mock tool does include a dummy libselinux library that returns 0 for
all calls to is_selinux_enabled(). This library is LD-PRELOAD-ed for
calls to yum to install packages into the chroot. However, it is not
LD-PRELOAD-ed for any other operation, such as running "useradd" or
"rpmbuild" in the chroot. In FC2, this results in a hangup when the user
is prompted for a new context to use if the host system has SELinux
enabled.
I tried building an FC2 libselinux package with the is_selinux_enabled()
hack to install into the chroot so that this wouldn't happen, but this
appeared to have no effect. Further investigation revealed that although
I had included the hack patch in the libselinux package, and that
package was being installed into the chroot, I actually forgotten to
*apply* the patch in the hacked libselinux package and it was therefore
identical to the original FC2 libselinux package. D'oh!
After configuring mock to install the properly-hacked libselinux package
into the chroot, it appears to be building packages successfully now.
Phew!
I'll try it on a few more packages and if all seems well, I'll update
the Legacy/Mock wiki page with the new information.
Paul.
