https://bugzilla.mindrot.org/show_bug.cgi?id=3560

            Bug ID: 3560
           Summary: Memory leak in channels.c
           Product: Portable OpenSSH
           Version: 8.5p1
          Hardware: Other
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: ssh
          Assignee: unassigned-bugs at mindrot.org
          Reporter: m.schmidt at emtec.com

Created attachment 3690
  --> https://bugzilla.mindrot.org/attachment.cgi?id=3690&action=edit
A few lines of code to fix the channels leak.

Function channel_free_all(struct ssh *ssh) misses to free some of its
elements:
- channel_pre
- channel_post
- and the permitted_user and permitted_adm from local and remote perms

This was found through a memory leaking tool (I'm building on Windows
Visual Studio with memory leaks enabled).

I would suggest to add something akin to the attached to the bottom of
channel_free_all(struct ssh *ssh)
