[HTCondor-users] Condor 8.9.* and USE_PID_NAMESPACES

[Bert DeKnuydt <Bert.DeKnuydt@xxxxxxxxxxxxxxxx>]

Dear Condorese,

Has anyone been able running jobs with

  USE_PID_NAMESPACES = True

under the current development series?

We've been using PID_NAMESPACES since many many years
without any trouble at all, but from 8.9.* it seems
broken for me.

In 8.9.4, it seemed like that condor_pid_ns_init didn't output
its ".condor_pid_ns_status" to the expected place.

In current 8.9.8, I get something along this:

08/11/20 14:17:22 (pid:72741) Running job as user xyzzy
08/11/20 14:17:22 (pid:72741) About to exec 
/usr/libexec/condor/condor_pid_ns_init 
/users/visics/xyzzy/condor/testscript.sh
08/11/20 14:17:22 (pid:72741) Warning: Create_Process: failed to read 
child process failure code

with errno 1 (Operation not permitted) before exec()
08/11/20 14:17:22 (pid:72741) 
Create_Process(/usr/libexec/condor/condor_pid_ns_init,/users/visics/xyzzy/condor/testscript.sh, 
...) failed: (errno=1: 'Operation not permitted')
08/11/20 14:17:22 (pid:72741) Failed to start job, exiting

Higher debug levels available on demand.

The exec /usr/libexec/condor/condor_pid_ns_init is correct and can be 
run manually
(with the environment variable trick).

With USE_PID_NAMESPACES = False, all works okay.

Greetings, Bert.
