The Logs page shows who added, changed or deleted a compute, from web
or API, and every login, failed login, lockout and logout, with the
client address and a Result column (Done, Failed, Unknown for older
rows). A failed change is recorded with its reason and the error still
reaches the user; a refused one is recorded too.
- logs.audit.write saves each row in its own savepoint and never
raises, so a log write cannot break or undo the action it records.
The audit() context manager writes one row when the change ends.
- Logs gains success and ip; user, host and instance are wider and
date is indexed. The page orders by date then id.
- A compute edit names the changed fields; an edit that changes
nothing writes no row, and an empty password field is no change.
- A compute's VMs leaving the panel get a system row each: owners
kept on the Removed VMs page, moved to another compute, restored,
left without owners, or the removed record expired.
- Job rows carry the result. A job's log entry that cannot be
computed is logged and skipped instead of rolling back the finish
(test_service.py changes this on purpose).
- Logins are recorded by signal receivers; CustomLoginView is removed
and the plain LoginView is used. A wrong OTP code is a failed login,
counted by django-axes toward the lockout.
Panel records and host-side objects follow in the next layers.
Several views returned json.dumps() output through HttpResponse, i.e. as
text/html, and guess_mac_address reflects the URL's vname into it
(reflected XSS). Templates filled the log table and volume dropdowns by
concatenating server data into HTML strings, and log messages contain
user-entered snapshot/disk/clone names (stored XSS that runs when a
superuser opens the Logs tab).
- Use JsonResponse in guess_mac_address, random_mac_address,
guess_clone_name, sshkeys, storages.get_volumes,
datasource.os_metadata_json and logs.vm_logs; sshkeys?plain=true is
served as text/plain.
- stats_tab.html builds log rows with .text(); instance.html and
create_instance_w2.html build <option> elements with .val().text().
