            Bug ID: 3024
           Summary: Socket not removed after closing the session
           Product: Portable OpenSSH
           Version: 7.9p1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: ssh
          Assignee: unassigned-bugs at mindrot.org
          Reporter: bugzilla at terrortux.de

Description of problem:
When using the socked forward via -L then after closing the session the
socket created on the locale side are not removed.

Version-Release number of selected component (if applicable):
openssh-clients-7.9p1-5.fc29.x86_64


How reproducible:
Every time


Steps to Reproduce:
1. ssh foo -L /tmp/foo:/var/lib/mysql/mysql.sock
2. close the connection
3. ssh foo -L /tmp/foo:/var/lib/mysql/mysql.sock

Actual results:
The 3rd call will fail with:
unix_listener: cannot bind to path /tmp/foo: Address already in use
Could not request local forwarding.

Expected results:
Working forward.

Additional info:
ssh foo -L /tmp/foo:/var/lib/mysql/mysql.sock
rm /tmp/foo
ssh foo -L /tmp/foo:/var/lib/mysql/mysql.sock
Will work, so nothing will use the socket.

See the Red Hat Bugzilla for the whole communication.
