After the synchronous waitpid(create_pid) succeeds, create_pid was never reset to -1. If the PID was later reused by another process, on_sig_exit() would send SIGTERM to that unrelated process. Resolves: RHEL-178025

Subject: [PATCH] Reset create_pid after waitpid to prevent signaling unrelated
|
|
processes
|
|
|
|
After the synchronous waitpid(create_pid) succeeds, create_pid was
|
|
never reset to -1. If the PID was later reused by another process,
|
|
on_sig_exit() would send SIGTERM to that unrelated process.
