Mike, didn't you say something about SA_RESTART in the original CL?

we are setting SA_RESTART already in the forwarding handlers.  mj shouldn't exit for any signal ... it should forward them all and only exit once its child does.

that said, i can't reproduce this report.  it's working for me.  are you testing minijail as it exists in CrOS today ?  that hasn't been rolled yet to include the signal forwarding logic.

what i tested:
- test.c:
int main(int argc, char *argv[])
{
        signal(SIGTERM, SIG_IGN);
        while (1)
                sleep(100);
}
- run `./minijail0 ./a.out &`
- run `kill -TERM %1` and see minijail send SIGTERM to its child process and then go back to waiting (and child ignores it so nothing exits)
- run `kill -INT %1` and see minijail send SIGINT to its child process which now exits, so minijail itself exits

I tried reproducing your test but I'm seeing different results: after `kill -TERM %1` minijail terminates, orphaning a.out. I built minijail on my workstation at b9a7b16.

you'll need to use 98f4a938cbc4acaff5f06009af50bb4bf19e173b

That last commit fixes it. Thanks.

I'll tag a new Minijail release at 98f4a938cbc4acaff5f06009af50bb4bf19e173b.
