[Bug 1610499] Re: /bin/kill in ubuntu16.04 has bug in killing process group
I've been seeing the same problem - numerous services being shutdown, including cron, ssh and even a script I have running on the console to recover. The syslog shows that various systemd "targets" being shutdown, including: Default, Basic System, Timers, Paths, Sockets... This has correlated to running a script on our system (that has been running for many years on many systems) that finds and sends a kill signal to a ser2net connection before opening a remote console. This has been a nightmare on our Ubuntu 16 systems since upgrading from 14, and nearly a daily occurrence on one of them. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1610499 Title: /bin/kill in ubuntu16.04 has bug in killing process group To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1610499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

To xin (pursue) : you also can download procps-3.3.10 source code and compile it in ubuntu16.04, then you could replace /bin/kill with the binary you compile . in this way you dont need copy the libprocps.so.3 . -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1610499 Title: /bin/kill in ubuntu16.04 has bug in killing process group To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1610499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1610499] Re: /bin/kill in ubuntu16.04 has bug in killing process group
I met exactly the same problem when using hadoop in ubuntu 16.04, and copied /bin/kill in ubuntu14.04 to ubuntu16.04 following Dongdong88's suggestion. However it renders /bin/kill simply unusable due to the lack of shared library (the built-in "kill" still works though). I created a link file libprocps.so.3 in /lib/x86_64-linux-gnu and targeted it to libprocps.so.4.0.0. But I am not sure if that will make the issue come back again. We may try copying and use libprocps.so.3.0.0 in ubuntu16.04 if so. I haven't got a chance to test it yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1610499 Title: /bin/kill in ubuntu16.04 has bug in killing process group To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1610499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1610499] Re: /bin/kill in ubuntu16.04 has bug in killing process group
** Description changed:
when i run hadoop in ubuntu 16.04, ssh will exit, all process which
belong to hadoop user will be killed ,through debug ,i found the
/bin/kill in ubuntu16.04 has a bug , it has bug in killing process group
.
Ubuntu version is:
Description:Ubuntu 16.04.1 LTS
Release:16.04
(1)The way to repeat this bug
It is easy to repeat this bug , run “/bin/kill -15 -12345” or any like
“/bin/kill -15 -1” in ubuntu16.04 , it will kill all the process .
(2)Cause analysis
The code of /bin/kill in ubuntu16.04 come from procps-3.3.10 , when I run
“/bin/kill -15 -1” , it actually send signal 15 to -1 ,
-1 mean it will kill all the process .
(3)The bug in procps-3.3.10/skill.c ,I think the code "pid = (long)('0'
- optopt) " is not right .
static void __attribute__ ((__noreturn__)) kill_main(int argc, char
**argv)
{
case '?':
if (!isdigit(optopt)) {
xwarnx(_("invalid argument %c"), optopt);
kill_usage(stderr);
} else {
/* Special case for signal digit negative
* PIDs */
pid = (long)('0' - optopt);
if (kill((pid_t)pid, signo) != 0)
exitvalue = EXIT_FAILURE;
exit(exitvalue);
}
loop=0;
}
(4) the cause
- sometimes when the resource is tight or a hadoop container lost connection
in sometime, the nodemanager will kill this container , it send a signal this
jvm process ,it is a normal behavior for hadoop for hadoop could reexcute this
task. but with kill bug ,it kill all the process belong to a hadoop user .
