Hi all,
I'm trying to use the technique here
https://medium.com/@felixge/killing-a-child-process-and-all-of-its-children-in-go-54079af94773
.. to ensure all children/grandchildren of my exec of /bin/bash die along
with it, but I am getting the above 'operation not permitted' error when
trying to Start(). It works fine without Setpgid set, but when my /bin/bash
dies, any background children spawned from it are left running, adopted by
init (pid 1).
Any idea why setting syscall.SysProcAttr{Setpgid: true} might not work
with certain other attributes set? My program is a daemon running as root,
and sets Uid/Gid to another non-root user; it also uses github.com/kr/pty,
the Start() method of which also sets some other attributes, .Setctty and
.Setsid. I tried going through the golang stdlib startProcess() code and
related bits, but don't fully understand how all of these optional flags
interact.
Thanks,
-Russ
