I have a hard time believing this is a bug in the code. But more then likely this signal can not be sent, and not sure why this is a stopper.

Hmm, this is possible, I am not familiar enough with GNU/Linux of that particular signal to know any better. It's entirely possible you're right and can't be passed. It's a test stopper because we hae no guidance on what should/shouldn't get proxied, simple as that. So if it's special in some way, then we can skip testing it and close this. I'll poke around on google and see if there are any answers... -- You are receiving this mail because: You are on the CC list for the bug.

https://bugzilla.redhat.com/show_bug.cgi?id=1096276 --- Comment #5 from Lukas Doktor <ldoktor(a)redhat.com> --- I'm not sure either. The only think I know is that when you try the same using pure bash it's able to receive it (the only missing signals are: 17 SIGCHLD 19 SIGSTOP (puts process in background) 20 SIGTSTP 21 SIGTTIN (works with docker, probably xterm problem) 22 SIGTTOU (works with docker, probably xterm problem) The 27 is handled properly using simple bash. I guess it might be used by go somehow? In such case I'd gladly accept man page modification as a solution. -- You are receiving this mail because: You are on the CC list for the bug.

https://bugzilla.redhat.com/show_bug.cgi?id=1096276 --- Comment #6 from Chris Evich <cevich(a)redhat.com> --- Thinking about it more, I think some good docs on what to expect with --sigproxy would be probably be good enough for now. Icing on the cake would be logged debug messages or docker events regarding proxied signals. Either or both would greatly reduce the amount of guessing needed in terms of what is expected to work, what is unreliable, and what is unlikely to work. -- You are receiving this mail because: You are on the CC list for the bug.

In short, all signals save 17 work properly. Signal 17 is not proxied by design. I've submitted a docs patch to clarify that sig-proxy does not actually forward signal 17.

https://bugzilla.redhat.com/show_bug.cgi?id=1096276 --- Comment #11 from Lukas Doktor <ldoktor(a)redhat.com> --- Hi Matthew, from the discussion I'm not sure, what the fix looks like. I found `SIGCHLD is not proxied` in the `docker-1.0.0-10.el7.x86_64` man page. How about the SIGCONT, SIGSTOP and SIGPROF (well and SIGKILL, it only kills the run/attach and the container is still running :-D)? Can you please point me to the documentation, where can I find them? -- You are receiving this mail because: You are on the CC list for the bug.

I'm hesitant to document the remaining few (SIGCONT and SIGPROF) given that they are technically Golang bugs - if they're fixed, the documentation would no longer be accurate. -- You are receiving this mail because: You are on the CC list for the bug.

SIGCHLD, SIGSTOP, and SIGKILL are not proxied. The default is true. Althought, Matthew, I thought about your concern with golang signals. CI should cover them so in case this test starts passing we will create bugzilla to remove the signals from man pages. Would that be acceptable?
