CC'ng basesystem as the script does nothing but killall5 option. I believe this would be better suited for sysvinit folks to handle.
I'm re-assigning this to base-system, since it is an issue with killall5 and not openrc.
sysvinit typically gets baselayout because it is integrated closely ignoring that, look at the error message. it doesnt appear to be coming from `killall5`, it's coming from the attempted execution of killprocs. if `killall5` was screwing up, it'd start with "killall5: ...".
Do you have rc_logger set to "yes" in /etc/conf.rc? If not, please do so then the next time you get this message, re-open this bug and attach /var/log/rc.log. Thanks much. William
I just got more information. If you are using parallel startup (if you have rc_parallel set to yes), andyou have logging turned on, this could be causing interfeerance that could cause the issue.
No more errors after turning off logging and parallel startup. And I need neither of them.
All, Since this has turned out to be a parallel startup/shutdown issue and rc.conf states clearly that you use parallel startup at your own risk, I think this should not block stabilization.
(In reply to comment #8) > All, > > Since this has turned out to be a parallel startup/shutdown issue and > rc.conf states clearly that you use parallel startup at your own risk, I > think this should not block stabilization. > FWIW, I've definitely seen this on occasion on my system, and have never turned parallel on and off. It happens incredibly irregularly, and I can't see any negative effects after the shutdown describes this error. Probably not worth re-opening, since I don't have anything more (or logs, as it hasn't occurred in a week or two), but it's definitely *not* related to parallel ism, as I've never had this enabled on my machine. Running a stable tree, with openrc/BL2 in package.keywords.
it's a bug and needs fixing
Created attachment 256149 [details, diff] Avoid race condition when closing pipe in runscript.c Under normal conditions runscript creates one child and waits for its termination, the termination is signaled by a pipe write from the SIGCHLD sighandler. When running killprocs however more than one SIGHCLD signal is generated, at least on all of my amd64 boxes running on real hardware and in vmware. When the first SIGCHLD occurs svc_exec leaves the loop and closes the pipe. Subsequent SIGCHLDs during the close can lead to a race condition and create an EBADF error in the pipe write (pipe is closed but the file handle is still != -1). The patch avoids this by blocking SIGHCHLD during the pipe close.
This patch is included in openrc-0.6.7. Please re-open if this issue continues after you upgrade. Thanks, William
