Unticking 'Save password' only disabled auto-connect: the dialog still handed
the stored verifier to the connection, so a password typed at the same time was
ignored, and a server that still has the legacy hash refused the login before it
could upgrade the account.
Clear the verifier in effect on untick, restore it on re-tick unless a password
has been typed, and drop the stale 'Password saved' hint. The downgrade abort
can now point at unticking the box and logging in with the password, without the
extra reconnect round-trip.

* [Security] Add challenge-response auth with scrypt verifiers and stop storing plaintext passwords
Challenge-response authentication: the client derives a scrypt verifier
(RFC 7914, EVP_PBE_scrypt, N=32768, r=8, p=1) and authenticates with
HMAC-SHA256(key, nonce), so neither the password nor its hash is
transmitted. The stored format becomes
"$scrypt$<n>$<r>$<p>$<salt>$<verifier>" and Response_PasswordSalt
now carries the cost parameters. Strict servers only accept scrypt
verifiers; legacy accounts are migrated after a successful login.
Fix#344 for challenge-response servers: a saved profile stores the
derived verifier under the password key instead of the plaintext password.
The connect dialog loads it without revealing it, autoconnect passes it
through, the change-password dialog no longer prefills the old password
field with it, and the client only persists the verifier when
"Save password" is checked.

* [Security] Harden credential format acceptance and challenge nonce validation
* [Security] Refuse KDF downgrade; trim profile name and warn on silent credential drop
* [Security] Add SupportsAll ServerOptions enumerator to fix enum validation assert
The server advertised both SupportsPasswordHash (1) and
SupportsChallengeResponseAuth (2) via a bitwise-OR that produced the
value 3, which no enumerator declared. Protobuf's proto2 enum
validation rejects the value in _internal_set_server_options, crashing
servatrice on the debug assertion. Add a SupportsAll = 3 enumerator with
an identical wire value so the bitmask reads unchanged while the value
is now a documented, valid member of the enum.
* [Security] Normalize username when issuing challenge nonce
cmdRequestPasswordSalt bound the challenge nonce to the raw, un-simplified
username while cmdLogin verifies it against the simplified name. A user
who typed leading or trailing whitespace in the username box would be
silently rejected during challenge-response login even with the correct
password. Simplify at the nonce-issuing site so both commands agree on
the normalized name.
Also drive-by formatting: collapse the now single-expression
serverOptions initializer onto one line.
* [Security] Keep an encrypted legacy password backup for old-client logins
Migrating an account to scrypt stranded pre-challenge clients, which can
only present the legacy salt+hash: after migration the server served them
a scrypt salt they cannot use, so the only recovery was a password reset.
When security/legacy_backup_key is configured (64 hex chars,
openssl rand -hex 32), submitPasswordVerifier now seals the legacy
credential with AES-256-GCM under that key before overwriting the row,
storing it in password_legacy_backup with the time it was last used. Old
clients keep working: cmdRequestPasswordSalt serves the backup's 16-char
salt in password_salt so they can derive the legacy hash they were
always able to compute, while new clients derive the verifier from the
new scrypt_salt field, which always carries the verifier salt. The
non-challenge login path accepts the plaintext or legacy hash against
the decrypted backup and refreshes its window; a migrated row with no
usable backup fails closed.
Backups age out so a database dump taken after the window closes never
carries a crackable legacy hash: getUsableLegacyBackup purges on first
use past security/legacy_backup_ttl_days (default 90, clamped 1..3650),
and a six-hourly sweep drops backups idle accounts never touch.
changeUserPassword clears the backup since a new credential invalidates
it. Without a configured key nothing is sealed or purged, so a
temporarily missing key cannot destroy existing backups.
The AAD is the simplified user name on both sides, sealing the blob to
its row so it cannot be moved between accounts. Sealing failures
degrade to the previous lockout behaviour rather than blocking
migration. The columns extend the unmerged 0036->0037 migration, so the
schema version stays 37.
* [Security] Address review: proto compat, plaintext verify, AAD case, strict scope
Fix the two blockers and follow-ups from the 2026-10-16 review:
- Advertise challenge-response in a new supports_challenge_response
field instead of the ServerOptions enum and drop SupportsAll:
proto2 enums are closed, so already-released clients parsed
server_options = 3 as NoOptions and fell back to plaintext
passwords. server_options stays exactly SupportsPasswordHash
on the wire; old clients ignore the new field.
- Verify a plaintext password directly against a migrated scrypt
row with verifyPassword() so email changes (cmdAccountEdit)
and old clients sending password keep working without a
legacy backup key. Pre-hashed values are still checked
against the backup, and its TTL window is refreshed only
when the backup is what actually matched.
- Use the stored row name as the AES-GCM AAD on both seal
and open so a login whose case differs from the stored
name (utf8mb4_unicode_ci) still opens its backup.
- Require challenge-response in strict mode only for
registered SQL accounts (userExists gate), leaving
guest/unregistered logins and none/password auth
methods unaffected.
- Document in servatrice.ini.example that a captured
legacy hash can take over a not-yet-migrated account
and that strict only constrains registered SQL
accounts. Schema version is 38.
* [Security] Raise legacy backup TTL default to 180 days
Gives operators and slow-to-upgrade users a longer downgrade
window for pre-challenge clients before unused encrypted
legacy password backups age out.
* [Security] Fix servatrice.cpp formatting per clang-format-18
* [Security] Add missing forward declaration for Command_SubmitPasswordVerifier
The cmdSubmitPasswordVerifier declaration references the proto-generated
type, which otherwise does not name a type in this header and breaks
every C++ build.

* [DeckList] Apply include-what-you-use to libcockatrice_deck_list
* [IWYU] Apply include-what-you-use across the tree
Run one whole-tree IWYU pass over the libcockatrice_* libraries, the
Cockatrice client, Oracle, Servatrice and the test suite, so each
translation unit includes what it uses directly and forward-declares
what it does not need.
IWYU only analyses real translation units, never the moc code CMake
generates from Q_OBJECT headers, so it strips includes that moc output
silently relies on. Where a type is passed by value (or nested in a
QList/QMap) in a signal or slot signature, the generated moc code needs
the complete type; those includes are kept with an explanatory
`// IWYU pragma: keep`. The same holds for Q_DECLARE_METATYPE targets
such as QSqlDatabase.
A handful of includes are added by hand where callers brace-initialize a
const-reference parameter, which also requires the complete type.
Applied as a single commit on purpose: stripping includes from the
libcockatrice_* headers is precisely what breaks the client, test and
server translation units, and the fixes for those live in the same
translation units. Splitting by component would therefore leave
intermediate commits that do not compile.
All 426 modified Q_OBJECT/Q_GADGET headers were verified to be
moc-self-contained by compiling each generated moc_*.cpp standalone;
several built only because of moc include ordering in
mocs_compilation.cpp before the keep-includes were added.
* [Tooling] Emit public Qt headers and fix IWYU fallout CI found
Three problems the local build could not see, all because a green local
build only proves the configuration it was run under.
Private Qt headers. IWYU emitted private, lowercase Qt headers, and
qtypes.h does not exist at all before Qt 6.9, so the Debian 12 and
Ubuntu 24.04 jobs on Qt 6.4.2 failed to compile. The generator only
emitted a mapping when the capital header name mirrored the private one
(QAbstractAnimation for qabstractanimation.h), so qtypes.h, which is
wrapped by QtTypes instead, got no mapping and kept the private
spelling. Map it explicitly to <QtTypes>, which is public since Qt 5 and
provides the same typedefs either way, and rewrite the 100 affected
includes.
Do not generalize this to "prefer any Qt* wrapper". The table is
generated from whichever Qt is installed, and the wrappers are not
equally old: QtLogging only appeared in Qt 6.8 and QtMinMax in 6.5, so
that heuristic trades one breakage for another. Every other lowercase
header still in the tree has shipped publicly since Qt 5, so those are
left alone.
Platform-guarded includes. IWYU only sees the preprocessor configuration
it is handed, so it dropped an include that only the macOS branch of
main.cpp needs, and the macOS jobs failed on an undeclared
UrlSchemeEventFilter. Restore the include. Force-compiling every file
that carries a platform guard under Q_OS_MAC, Q_OS_MACOS and __APPLE__
reports nothing else, so the macOS branches are covered rather than
assumed.
shellcheck. Drop a leftover variable and stop assigning the
include-what-you-use lookup, which was only ever an existence check.
* [Tooling] Map Qt 6.5+ split headers to QtGlobal for Qt 6.4 compatibility
IWYU emitted QtTypes, QtPreprocessorSupport, QtVersionChecks, QtAssert,
QtMinMax, QtClassHelperMacros, QtEnvironmentVariables and QtTranslation.
Qt 6.5 split those declarations out of qglobal.h into separate headers, so
neither the Qt* wrapper nor the q*.h private name exists on the oldest Qt we
support (6.4.2), and Debian 12 / Ubuntu 24.04 fail with "No such file or
directory". qtypes.h is worse still: it only appeared in Qt 6.9.
QtGlobal is the one spelling that works across the whole supported range. It
has been public since Qt 5, defines these declarations itself up to Qt 6.4, and
includes the split headers from Qt 6.5 on, so redirect all eight private
headers to it and collapse the affected includes in the tree.
Curated overrides now take precedence over the name-mirroring rule, which
cannot know about Qt version floors because the mapping is generated from
whatever Qt is installed. That rule was mapping qtversionchecks.h to
<QtVersionChecks> even with an override present, because the override was only
consulted as a fallback. A curated key that matches nothing is now a hard
error rather than a silent fallback, and the redirected headers are no longer
advertised as the home of a symbol.
Verified every Qt include in the tree resolves against the real
qt6-base-dev 6.4.2 package: 15 distinct includes, 0 missing.
* [Tooling] Map QOverload to QtGlobal and drop the QMetaMethodArgument include
Two more headers IWYU emitted do not exist on Qt 6.4.2:
QOverload was split out of qglobal.h in Qt 6.5, so on 6.4.2 it is declared in
qglobal.h directly and the standalone header is a hard error. QtGlobal covers
both, so map qoverload.h to it like the other 6.5+ split headers.
QMetaMethodArgument is never referenced anywhere in the tree. It is a bare
forwarder for qobjectdefs.h that our generator advertised as a class symbol,
which is how IWYU came to add the include at all. The symbol mappings are
generated from header names, so they cannot tell a forwarder that happens to be
capitalised from a real class; removing the unused include is the fix, and the
generic case stays a known limitation of the generator.
Extending the audit to every Q* header (an earlier pass only matched headers
starting with "Qt" or lowercase q*.h, so it missed all of them) against the real
qt6-base-dev, qt6-multimedia-dev, qt6-declarative-dev, qt6-svg-dev and
qt6-websockets-dev 6.4.2 packages: 341 distinct Qt includes, 0 missing.
* [Game] Give moc the complete CardItem type in player_actions.h
player_actions.h forward declares CardItem but passes QList<CardItem *> by
value in actPlay/actPlayFacedown/actHide. moc instantiates the metatype for
those parameters, and on Qt 6.4 that expands to sizeof(CardItem), so Ubuntu
24.04 fails with "invalid application of 'sizeof' to incomplete type
'CardItem'". Newer Qt tolerates the incomplete type, which is why only the
6.4.2 jobs failed.
Include the defining header with an IWYU pragma keep, matching how the other
MOC-required includes in this area are handled.
* [Game] Give moc the complete ServerInfo_Card type
player_logic.h, game_scene.h, view_zone.h and view_zone_widget.h forward
declare ServerInfo_Card but pass QList<const ServerInfo_Card *> through signal
and slot signatures. moc instantiates the metatype for those parameters, which
Qt 6.4 expands to sizeof(ServerInfo_Card), so the connect in game_scene.cpp
fails on Debian 12 and Ubuntu 24.04 with "invalid application of 'sizeof' to
incomplete type 'const ServerInfo_Card'". Newer Qt tolerates it, so only the
6.4.2 jobs failed.
Include the generated protobuf header with an IWYU pragma keep, following the
pattern already used for ServerInfo_Player and ServerInfo_User in
game_event_handler.h.
* [Client] Complete the types Qt 6.4 needs for connect and moc
Qt 6.4 expands QMetaType::fromType on the normalised argument list of a
PMF connect and on moc-generated metatypes, which requires sizeof on every
signal and slot parameter. Newer Qt tolerates forward declarations there,
so only the Debian 12 and Ubuntu 24.04 jobs failed, with
"invalid application of 'sizeof' to incomplete type" for QMouseEvent,
QPrinter and GameReplay.
Replace the forward declarations with the real includes:
- QMouseEvent in the nine widget headers that pass it through signals
- QPrinter in abstract_tab_deck_editor.cpp, for the actPrintDeck lambda
- game_replay.pb.h in tab_replays.h. GameReplay is a protobuf message, so
the project's game/replay.h only forward declares it and cannot supply
the complete type.
Found by recompiling all 1918 project TUs against the Debian Qt 6.4.2
headers, which reproduces those two CI jobs locally in one pass.
* [Client] Complete Release and QMenu for Qt 6.4 moc and connect
Continuing the Qt 6.4 complete-type sweep:
- window_main.cpp connects ClientUpdateChecker::finishedCheck to
MainWindow::checkClientUpdatesFinished, whose Release * parameter made
moc 6.4 instantiate the metatype. GameReplay turned out to be a protobuf
message, so Release likewise needed release_channel.h in the three
headers declaring those signals: window_main.h, dlg_update.h and
client_update_checker.h.
- moc 6.4 also needs sizeof(QMenu) for the QList<QMenu *> carried by
TabSupervisor::setMenu and MainWindow::updateTabMenu.
Verified by regenerating moc output with the Debian moc 6.4.2 for all 434
Q_OBJECT/Q_GADGET classes and compiling it, plus recompiling all 1612
source TUs, against the Qt 6.4.2 headers: no remaining failures.
