Hi,
I did update the init script for stubby, that it runs with ujail. Stubby does
run, but it isn't possible to stop it via '/etc/init.d/stubby stop'. The ujail
process is stopped, but stubby itself not. It looks like that it isn't possible
to stop stubby with SIGTERM. Stubby will be ended by SIGKILL only. Procd sends
first SIGTERM and than SIGKILL to ujail, but ujail sends SIGTERM only. Either
ujail doesn't send SIGKILL if the jailed process doesn't terminate or procd
sends SIGKILL to early so that ujail can't send SIGKILL any more. In the log I
see the following messages:
Fri Dec 10 13:35:52 2021 user.err : jail: forwarding signal 15 to the jailed
process
Fri Dec 10 13:35:52 2021 daemon.err stubby[6669]: jail: forwarding signal 15 to
the jailed process
Fri Dec 10 13:35:57 2021 daemon.info procd: Instance stubby::stubby pid 6669
not stopped on SIGTERM, sending SIGKILL instead
6669 was the pid of the ujail process.
In ujail, I changed a few DEBUG() calls to ERROR(). Without this, the first two
lines are not shown.
Any ideas?
Regards,
Hartmut
