Public bug reported:
Example where the subprocess 115576 has not been terminated:
root@ubuntu:~/sudebug/src/shadow-4.1.5.1/src# pkill sleep; ./su test -c 'sleep
9999'&
[1] 115575
root@ubuntu:~/sudebug/src/shadow-4.1.5.1/src# kill $!
root@ubuntu:~/sudebug/src/shadow-4.1.5.1/src# ...waiting for child to
terminate.
pgrep sleep
115576
[1]+ Exit 255 ./su test -c 'sleep 9999'
root@ubuntu:~/sudebug/src/shadow-4.1.5.1/src# pgrep sleep
115576
Expected behavior:
root@ubuntu:~/sudebug/src/shadow-4.1.5.1/src# pkill sleep; ./su test -c 'sleep
9999' &
[1] 115503
root@ubuntu:~/sudebug/src/shadow-4.1.5.1/src# kill $!
root@ubuntu:~/sudebug/src/shadow-4.1.5.1/src#
Session terminated, terminating shell... ...terminated.
...terminated.
[1]+ Exit 143 ./su test -c 'sleep 9999'
root@ubuntu:~/sudebug/src/shadow-4.1.5.1/src# pgrep sleep
