The retry counter is there to ride out a few unanswered polls, but
exhausting it broke out of the loop with complete still unset and fell
through to the 'complete' return, so an SMM that stopped answering
part way through an apply was reported to the operator as updated.
Raise instead; a genuine finish still leaves the loop on the progress
reaching 100.
Now that the expiry comparison actually caches a client, the session it
holds is shared, so tearing it down and replacing it needs the same care
the IMM handler already takes:
Dispose of an expired session with a logout instead of dropping the
reference, otherwise every refresh leaves an authenticated session
behind on an SMM that only has a handful of slots. That logout has to
tolerate a session the SMM has already reaped, hence the except.
Guard the login itself, so two coroutines arriving at an empty or
expired cache do not both log in and orphan one of the two sessions.
Stamp the vintage once the login round trips are done rather than
before, so a slow SMM cannot hand back a client that is already expired.
The old WebConnection.request() added a
'Content-Type: application/x-www-form-urlencoded' header to any POST
carrying a body, but grab_response_with_status() only sets a content
type for dict payloads, so the SMM login and every /data form POST now
go out as text/plain. This is not a fix for an observed failure: an SMM
running FPC variant 38 was measured accepting a text/plain login exactly
as readily as a urlencoded one. It restores the header the synchronous
code always sent and that the TSM and IMM handlers still set explicitly,
rather than relying on every SMM firmware level being equally lax about
what it will parse.
Also stop hard failing on responses the synchronous code discarded on
purpose. 'set=securityrollback:1' is only understood by newer SMM2
firmware. And /data/logout answers 401 once the session is gone, as
measured on that same SMM, so raising on a non-200 there turns a
completed hostname, domain or NTP operation into a spurious error.
The SMM hostname, domain, and NTP helpers looked synchronous even though their web transport is asynchronous. Removing awaits in the Lenovo OEM handler therefore returned unresolved coroutine work instead of completed settings results.
Convert the SMM settings and logout helpers to the asynchronous web interface, validate HTTP status responses, and await each operation from the OEM handler so callers only observe completed results.
The NextScale SMM path still used the removed http.client-style interface against the asynchronous WebConnection implementation. Login, configuration, diagnostic, and firmware operations consequently called unavailable methods or left request coroutines unresolved.
Make web-client creation asynchronous, migrate the affected requests to grab_response_with_status(), and await the cached client accessor. Correct the cache expiry comparison so fresh authenticated clients are reused and stale clients are renewed.
os.path.join(ConfigManager._cfgdir, '/tenants/') discards the cfgdir
because the second component is absolute, so it resolves to /tenants/
rather than <cfgdir>/tenants.
Tenants are not used yet but let's not face this issue in the future.
Rename the format parameter to fmt to stop shadowing the builtin,
pass the already parsed key data dict directly to _restore_keys
instead of reserializing it, use yaml.safe_dump for symmetry with
the safe loader, and consolidate the five repeated per-format dump
blocks into one helper.
Diskless profiles had the updatestatus callback in onboot.sh commented
out because no suitable status existed: 'complete' clears
deployment.pendingprofile, which the PXE responder requires to answer
the next network boot of a diskless node.
Add a 'booted' status that records the pending profile as
deployment.profile while leaving pendingprofile armed and skipping
autolock, and enable the onboot.sh callback in all diskless profiles.
nodedeploy now shows 'pending: <profile> (booted)' for a running
stateless node.
PyYAML implements YAML 1.1 implicit typing, so hand edited values like
'yes', '52:54:00:12:34:56', or '2026-07-17' in a YAML dump would be
restored as bool, sexagesimal int, or date instead of strings (the
date additionally crashing the JSON re-serialization). Load with a
SafeLoader subclass that only implicitly types scalars the PyYAML
dumper would have quoted when emitting strings, keeping dump/restore
round trips faithful.
Restoring a YAML dump without --yaml (or vice versa) previously
reported 'Cannot restore without keys, this may be a redacted dump'.
Point at the actual format of the dump instead when the keys file
exists in the other format.
The following post install steps were missing on Ubuntu builds:
- Permission fixes
- sysctl load
- Service restart
- confluent PAM symlink to /etc/pam.d/sshd. It works without it on
Ubuntu because it falls back to other which allows login on Ubuntu,
but the behaviour should be the same on every OS. Furtheremore, an
admin might implement additional steps to sshd PAM and would like to
have this in Confluent, too
The CA database under /etc/confluent/tls/ca is typically created by a root context such as osdeploy initialize -t, but the confluent service runs as the owner of /etc/confluent, and openssl ca rewrites the database (index, serial) as the invoking user on every issuance. Certificate issuance through the running service (e.g. the /self/tlscert deployment API) then fails on the root-owned database until packaging happens to repair the ownership.
Run the CA creation (full CA and the currently unused simple CA variant) and the openssl ca invocation under normalize_uid, the convention already used when publishing the CA certificate. The issued certificate is staged through a temporary file since the destination may only be writable by the invoking user, e.g. the web server certificate paths.
Existing root-owned CA databases are repaired by packaging or manually via: chown -R --reference=/etc/confluent /etc/confluent/tls
Apply ruff's safe autofixes.
The changes are mechanical and behaviour-preserving. Issues fixed:
- F401: remove unused imports.
- F841: drop unused local variables and assignments, including discarded
await/return values, unused "except ... as e" bindings, and unused
"with ... as name" targets.
- F541: remove the f prefix from f-strings that contain no placeholders.
- E711: compare against None with "is"/"is not" instead of "=="/"!=".
- E712: test truthiness directly instead of comparing to True.
- E713: use "x not in y" instead of "not x in y".
- E714: use "is not" instead of "not ... is".
- E731: convert lambdas bound to a name into def statements.
- W291/W293: trim trailing whitespace on touched lines.
Before the async port the bmc var was used for a "host=bmc" parameter
which does not exist anymore.
Now add [] around IPv6 addresses with missing brackets but keep the scope zone like %eth0
as this is needed in current code.
The IPMI 1.5 session-challenge callback returned coroutine objects from error reporting and session activation instead of expressing an asynchronous callback contract directly. That made completion depend on the dispatch path noticing and awaiting the returned object.
Make the callback asynchronous and explicitly await both onlogon() and _activate_session(), ensuring failure notification and activation finish before callback dispatch continues.
