https://bugzilla.mindrot.org/show_bug.cgi?id=1905 Summary: check_parent_exists() logic does not cover all cases Product: Portable OpenSSH Version: 5.8p2 Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: ssh-agent AssignedTo: unassigned-bugs at mindrot.org...

The check_parent_exists() function in ssh-agent.c does this: if (parent_pid != -1 && kill(parent_pid, 0) < 0) however, the kill can fail with EPERM even if the parent_pid exists. For example, consider this command: ssh-agent sh -c 'ssh-add ; exec sudo sh -i' The original ssh-agent...

...gent.c) this isn't what actually happens. It looks like the agent lives on as the subprocess, and the subcommand is execed from the parent process. This has troublesome implications for the agent being able to detect when the command dies, since it can't rely on SIGCHLD handlers. Indeed, check_parent_exists() relies on simply storing the process ID and checking to see whether such a process is signalable. Given that process IDs tend to be relatively small numbers (15 bits on Linux), and are reused frequently, it's not hard to imagine this test giving a false positive. It's also troublesome...

I did now try many different drivers from different vendors none of them worked thus I think there is something else wrong. I then did some more tests, trying to find anything being
