Closes the cred-coverage gap for two database services that had been
capturing only the username:
- MySQL — extends _handle_packet to read the auth-response after the
null-terminated username. mysql_native_password puts a 1-byte
length followed by 20 bytes: SHA1(password) XOR SHA1(salt +
SHA1(SHA1(password))). Plaintext irrecoverable, lands as
secret_kind="mysql_native_password" with the 20 hash bytes in
secret_b64. Hash is canonical for "hashcat -m 11200" if an operator
ever wants to crack offline.
- MSSQL — fixes a pre-existing bug AND adds password capture. The
prior _parse_login7_username read offsets 36/38, which is actually
ibHostName/cchHostName in the Login7 layout — username sat at
40/42 and was never touched. Replaced with _parse_login7_creds()
reading the correct offsets (40 username, 44 password). Login7
password is XOR-then-nibble-swap obfuscated against 0xa5;
_deobfuscate_login7_password reverses it. Plaintext-recoverable,
lands as secret_kind="plaintext".
The pre-existing test_login7_auth_logged_and_closes only verified the
error response ships and the connection closes; it didn't validate
the parsed username, so the hostname-as-username bug was silent. New
tests cover both the deobfuscation algorithm directly and the full
ingester round-trip for both services.
Sync: copies the canonical syslog_bridge.py into mysql/ and mssql/
template build contexts so service_testing tests load the version
with classify_authorization + encode_secret available.
37 tests pass in the touched scope. Phases 3-7 still pending.
Every service template now pulls version strings, cluster/node UUIDs, auth
salts, greeting banners, and uptime from the seeded per-instance RNG instead
of hard-coded defaults. Scanners sweeping the fleet now see legitimately
diverging fingerprints per decky while each decky's own responses stay
internally consistent across restarts.
Covers elasticsearch, ftp, http, https, ldap, mongodb, mqtt, mssql, mysql,
postgres, redis, and smtp templates.
The docker build contexts and syslog_bridge.py lived at repo root, which
meant setuptools (include = ["decnet*"]) never shipped them. Agents
installed via `pip install $RELEASE_DIR` got site-packages/decnet/** but no
templates/, so every deploy blew up in deployer._sync_logging_helper with
FileNotFoundError on templates/syslog_bridge.py.
Move templates/ -> decnet/templates/ and declare it as setuptools
package-data. Path resolutions in services/*.py and engine/deployer.py drop
one .parent since templates now lives beside the code. Test fixtures,
bandit exclude path, and coverage omit glob updated to match.
