3fc11c0f81 port forward shared conn (#16062)
* hbb_common: bump to the port-forward-mux proto

Also latches PortForward.multiplex into login_scope_digest, which
destructures PortForward's fields exhaustively by design (a new field
must be latched or deliberately ignored to compile).

* port_forward_mux: fix RecvWindow counter overflow on long transfers

Replace cumulative accounting (granted/received) with remaining credit
tracking to prevent u32 overflow after 4 GiB of data on a single channel.
Wire behavior is identical, but the fix allows large file transfers
without mid-stream channel closure.

Add regression test for 8 GiB transfer to verify fix.

* server: multiplexed port-forward connections stay in the protobuf loop

Wire PortForwardMux into Connection: take the multiplexed path at login
when the controller sets PortForward.multiplex, route
PortForwardChannel frames to it from on_message, sweep the channel
table's targets after open/close, and clean it up on connection close.

Introduce is_port_forward() (socket-based or multiplexed) and use it
at the four sites that classify the connection, so a multiplexed
connection stays in the message loop, gets TestDelay keepalives, and
reports features.port_forward_mux in PeerInfo. The three sites that
break into the raw pipe loop or gate the keepalive still check
port_forward_socket specifically, since a multiplexed connection must
not take that path.

Publishing after spawn let a loop that dies immediately reset the state

concurrently opened channels, and drops an unused Clone derive.

* port_forward_mux: fix bulk test's premature half-close, pin the half-close limitation

many_channels_echo_concurrently_and_a_bulk_one_does_not_starve_them dropped
its bulk write half as soon as writing finished, which shuts down the write
side of the socket and, by design (see the design doc's TCP half-close
non-goal; today's run_forward does the same), ends the whole channel. Keep
the write half alive until the reader is done so the test measures
starvation, not half-close. Add a_local_half_close_ends_the_whole_channel to
pin that limitation in code.

* port_forward_mux: cap send credit and other final review fixes

Fix 1 (critical): clamp SendCredit to MAX_SEND_CREDIT (= CHANNEL_WINDOW)
in both new() and add(), so a peer with tunnel permission can no longer
advertise an unbounded window and force the controlled side's unbounded
FrameSink::Direct sink to buffer unlimited target data per channel.

Fix 2: rename the "starve" test to many_channels_echo_concurrently and
drop its (untrue) starvation claim, since it opens every channel before
the bulk transfer starts. Add a_channel_opened_during_a_bulk_transfer_
is_served_promptly, which opens the small channel while the bulk one is
demonstrably mid-flight.

Fix 3: only look up the tunnel permission for `open` frames in the
PortForwardChannel arm of on_message, instead of once per data frame.

Fix 4: two rustfmt deviations in connection.rs (matches! wrapping and a
tuple literal), fixed by hand without a blanket cargo fmt run.

* port_forward_mux: report a refused channel's reason as an error dialog

The controlled side already answers a refused port-forward channel with
opened { success: false, message }; on the multiplexed path TunnelHandle::
on_frame only logged that message at debug and closed the channel, so the
user saw a closed connection with no explanation, worst on the RDP path
where only the RDP client's own error remained. on_frame now returns the
message the window should show, deduplicated per distinct reason (capped
at MAX_REPORTED_OPEN_ERRORS) so one page load's dozen refused connections
surface one dialog per reason instead of a dozen.

* port forward: apply the whole-branch review

Correctness:
- listen(): the Legacy arm is merged with the Claimed arm. On its own it
  ignored outcome.local_eof, so a client that hung up during login still
  got a target connect, an audit record and a CM row on the controlled
  side, and ignored outcome.mux, so a peer upgraded while a legacy window
  stayed open answered as a tunnel while the controller went raw.
- Refusal dialogs are deduplicated per quiet spell (10 s) rather than per
  tunnel lifetime; the lifetime set went silent for the rest of a
  long-lived window after the first burst.
- Android's CM listener handles UpdatePortForward; it fell into `_ => {}`.
- relay_socket_to_tunnel reads into one scratch buffer per channel and
  sends an exact-size copy. A frame owning its 64 KiB read allocation
  pinned it until sent, once per byte on interactive traffic.

Consistency and cleanups:
- The controlled side's refusal text is the raw pipe's wording, RDP
  substitution included.
- connection.rs: the PortForwardChannel arm is a one-line hook, the CM
  label is pushed from the 1 s tick alone, and the unreachable inner.tx
  fall-through is gone.
- The Ready enum is removed; wait_ready() returns Option<Claim>.
- SendCredit::add wakes with notify_one alone.
- on_ui_command() replaces the two ui_receiver handlers in listen().
- TunnelHandle is no longer re-exported (unused-import warning).

* port forward: a legacy window stays legacy until it is reopened

Review: the merged `Claimed | Legacy` arm gave a legacy window a hot
transition to a tunnel — every accept re-negotiated, and a peer upgraded
while the window stayed open was promoted underneath live connections.
The product does not need a mode switch inside a window's lifetime, and
the transition was extra state-machine surface for nothing: reopening
the window picks up an upgraded peer.

The two arms are separate again. `Claimed` negotiates once and the
peer's answer fixes the window's mode. `Legacy` logs in for every accept
as before, asks for no tunnel — `LoginConfigHandler::port_forward_mux`
carries the request per login, so the raw pipe never has to talk to a
peer that thinks it agreed to multiplex — and ignores what the peer
reports. Both arms keep skipping a local socket that hung up during
login.

* server: admit only INITIAL_WINDOW on a channel before opened

The demultiplexer accepted CHANNEL_WINDOW into a pending channel's
unbounded queue, four times the bound the channel task enforces once
it polls. The window now starts at INITIAL_WINDOW and is widened right
before `opened` advertises the rest.

* port_forward_mux: a tunnel ends when its window drops the Tunnel

The loop held its own handle and state sender, so once the window
closed nothing was left to stop it: it kept answering TestDelay and the
peer connection, CM row included, lived on until the peer went away.
`Tunnel` now owns a watch sender nobody sends on; the loop's receiver
errors when the last `Tunnel` drops, and the loop ends.

* port forward: one tunnel per mapping, bound to the authenticated target

The login latches `PortForward.host`/`port` into the session scope and
approval is shown that target, but a window-wide tunnel let any later
`open` name another target with only `enable-tunnel` rechecked. A
tunnel now belongs to one listener and serves the one target its login
authenticated: the controlled side refuses an `open` for any other
target, and a window with several targets uses one connection each,
approved on its own.

With one owner per tunnel the claim needs no waiters: `Establishing`,
`Claim::Wait` and `wait_ready` go, and `try_claim` becomes a plain
read. The CM label that followed a tunnel's targets goes with them; a
row shows its mapping's target, as before.

* port_forward_mux: a window violation drops the channel on the spot

Both demultiplexers only queued a `Violation` and left the entry until
the channel task woke and exited, so a peer that kept sending past the
window queued one more entry per frame in the meantime, bounded by
nothing. The entry now goes the moment `accept` fails; later frames for
that id are unknown-channel noise.

* port forward: the login's target travels with the accept, not the handler

`listen()` wrote `lc.port_forward` (and, on this branch, `port_forward_mux`)
into the window's shared `LoginConfigHandler` before connecting, and
`create_login_msg` read them back only when the peer's `Hash` arrived.
Two mappings logging in at the same time could therefore swap targets:
on master that bridged a local socket to the wrong target, and with a
tunnel bound to its login's target it also left the mapping refusing
every later accept until it was recreated.

The target is now a `PortForward` carried by the interface clone that
handles one accept, passed explicitly down to `create_login_msg`; the
handler no longer has a field to race on. No lock spans the login.

* port_forward_mux: pin permission revocation and whole-tunnel failure in tests

Both already hold; the review asked for them to be stated. `enable-tunnel`
turned off mid-session refuses the next `open` while the live channel
keeps relaying, and a dead tunnel ends every channel on it together,
after which the next accept establishes again on the same `Tunnel`.

* port forward: the raw pipe runs the code it always ran

The multiplexed login had replaced `connect_and_login`, so a mapping
with the setting off, a peer without the feature, or a listener latched
`Legacy` still went through the tunnel's state machine, the capped
pre-read and the changed local-EOF rule. Feature off now means the old
code: `listen()` keeps its accept arm and `connect_and_login` as they
were, and the tunnel is a branch taken only when the setting is on, in
`establish_tunnel` with its own `connect_and_login_mux`. The one line
the raw path does differently is the target riding with the accept's
interface clone instead of the shared handler.

`get_port_forward_mux_enabled` had one caller and moves in here, so
`common.rs` is untouched.

* port forward: a UI login answers the challenge its own connection was given

`handle_login_from_ui` hashed the typed password against `lc.hash`, the
window's shared handler field, and the window's password prompt is
broadcast to every listener. With two mappings both waiting on that
prompt, the `Hash` that arrived last had overwritten the other's, so
one of the two answered the wrong challenge and failed to log in.
Master shares the same state and broadcasts the same way.

The `Hash` is now a parameter of the login; `Session` keeps it beside
the connection it belongs to, and the per-accept clone that
`with_port_forward` makes gets a slot of its own. `lc.hash` stays for
`handle_peer_info`, which only needs the salt, and that is per peer.

* port forward: a mapping without its hash waits for it before answering the prompt

The window's password prompt is broadcast to every mapping, and can
reach one whose own connection has not received its `Hash` yet. That
mapping used to answer anyway, with a digest over an empty challenge:
the peer refused it and counted a failed attempt, and the empty-salt
result was written into the shared `lc.password`, where the mapping that
prompted had just stored the right one and the next `handle_peer_info`
would persist whatever was there.

The connection's challenge is now `Option<Hash>`, `None` until
`handle_hash` runs, and `handle_login_from_ui` sends nothing without it.
The mapping that prompted stores the salted password in the shared
handler, and the waiting one logs in with that against its own challenge
when its `Hash` arrives, without prompting again.

Test: A answers its prompt, the same broadcast reaches B before its
hash, B sends nothing, B's hash arrives and its login carries B's
challenge and B's target with no dialog. It runs the real `handle_hash`
for B.

* port forward: the tunnel's login is the raw pipe's, asked for by a window flag

Master's fix for the shared login slots (#16069) keeps the target and
the challenge in the window's `LoginConfigHandler` and serializes the
mappings' logins with a turn lock, all inside `port_forward.rs`. This
branch had carried a broader shape of the same fix, a `with_port_forward`
on `Interface` and the target and `Hash` as parameters through the login
functions, which every caller had to follow. That is gone: `Interface`,
`Session`, `create_login_msg`, `send_login`, `handle_hash` and
`handle_login_from_ui` are as on master.

What the tunnel needs on top is one bit in the login, `multiplex`. It is
a window flag beside `port_forward` in the handler, set once in `io_loop`
before the window's mappings start, so an accept's claim and its login
read the same value; the setting takes effect for windows opened after
it changes. `connect_and_login_mux` is now master's `connect_and_login`
with the tunnel's three differences and the same `hash_arrived` and
`login_from_ui` calls. The raw pipe is master's, line for line.

`enable-port-forward-mux` was readable only by editing the config file.

The two new keys are translated in every language. The three that the

Eight entries stay empty on purpose. They are keys that only ur.rs still

* port forward: closing the tunnel reaches channels parked on their socket

A channel whose far end neither reads nor writes has both relays parked
on the socket, not on the inbound queue, so `close_all` dropping the
queue's sender woke neither: the socket and both tasks lived on until
the far end hung up. Both sides now hold a per-tunnel teardown signal
that `run_channel` selects on beside its own cancel, and `close_all`

* port forward: a mapping latched to the raw pipe logs in without asking for the tunnel

The login copied the window's `port_forward_mux` into `multiplex`, so a
mapping that had latched to the raw pipe on an old peer kept asking for
the tunnel. Once that peer was upgraded it answered with a tunnel while
the controller switched to raw framing, and every later connection on
the mapping was dead until it was re-added. The login now carries its
own `port_forward_multiplex`, filled with the target under the turn
lock: the probe asks, the raw pipe does not.

* port forward: a channel opened as its tunnel closes still gets the teardown

`open` can straddle `close_all`: the claim passed, the frame receiver was
still alive, and the channel subscribed after the signal had gone out.
`watch::subscribe` marks earlier sends as seen, and the entry sits in a
map that was already cleared, so nothing would ever end it. The signal is
now a level: `close_all` raises it with `send_replace`, which stores even
with no channel live, and `run_channel` waits for the value rather than
for a change.

The codec takes a header declaring up to 1 GiB and hands the packet up
only once it has all arrived, so the channel window bounded what the

at 2 * MAX_FRAME as soon as multiplexing is agreed: a data frame with
its envelope and MAC fits with room to spare, and a header over the cap
ends the tunnel before a byte of payload is read. TCP only; the
WebSocket and WebRTC codecs carry caps of their own.

socket, so the new local connection's bytes went into the old target
connection. The id is now taken under the map's lock and advanced past
any id in use.

f28ac38ccf feat: optionally sync clipboard between connected sessions (#15934)
* feat(clipboard): optionally sync clipboard between connected sessions

Clipboard content received from a remote session is written to the local
clipboard with an owner marker, so the client clipboard loop deliberately
skips re-broadcasting it to avoid echo loops. As a result, text copied in
one remote window could not be pasted in another connected remote window.

Add an opt-in local option (allow-sync-clipboard-between-sessions) that
relays Clipboard/MultiClipboards messages received from one session to
all other connected sessions, excluding the source session. Per-session
clipboard permissions and view-only mode are still respected via the
existing send path, and the owner marker on the receiving peers prevents
any echo back.

Desktop (flutter) only; file clipboard is not affected.

* fix(lang): propagate sync-clipboard-between-sessions-tip to all locale files

Add the new key to template.rs and every locale file per the localization
convention, move the en.rs entry to the end of the list, and drop comments
that only restated the names next to them.

* fix(lang): add the 'Sync clipboard between sessions' label to the localization catalog

The checkbox label goes through translate(), so add it to template.rs
and every locale file so non-English locales can translate it. en.rs is
skipped since the English display text is identical to the key.

* fix(clipboard): check the source session's full clipboard permission before relaying

The relay was gated only by the incoming clipboard_allowed check
(!disable_clipboard && !view_only). Gate it with
is_text_clipboard_required() instead, which additionally respects the
source session's server_clipboard_enabled and server_keyboard_enabled
state, matching the predicate already applied to destination sessions.
A message arriving after the source permission was revoked (or from a
non-conforming peer) is no longer propagated to other sessions. The
existing local update_clipboard behavior is unchanged.

* fix(lang): translate the new clipboard sync entries in all locale files

Fill the 'Sync clipboard between sessions' label and its tooltip in
every locale file instead of leaving them blank, following each file's
existing terminology. template.rs keeps the empty master entries.

Remove MANAGE_EXTERNAL_STORAGE, READ_EXTERNAL_STORAGE, and
WRITE_EXTERNAL_STORAGE from the Android manifest. Remove
requestLegacyExternalStorage. Replace broad external storage with
app-scoped external storage for the file-transfer workspace.

File import uses the system file_picker. File export uses Android's
SAF ACTION_CREATE_DOCUMENT with path validation that restricts
export sources to app-owned directories.

Remove the external_path dependency.

* fix: android: use SAF for file imports

Replace file_picker imports with Android's Storage Access Framework to avoid legacy storage permissions, stale cached files, and duplicate staging of large imports. Stream selected documents into app-scoped storage with failure-safe replacement, keep exports restricted to validated app storage roots, use filesDir for the internal fallback workspace, and remove legacy permissions contributed during manifest merging.

7aa98d43cf Refact/plugin removal leftovers (#15864)
* fix(flutter): dispose the settings PageController and order dispose() correctly

`dispose()` began with `super.dispose()`, so the mixin chain marked the State
defunct before the WidgetsBindingObserver registration and the periodic timer
were released. The `PageController` was never disposed at all: `Get.delete`
only runs `onDelete()` for a `GetLifeCycleBase`, and a plain `ChangeNotifier`
is not one, so every open/close of the Settings tab leaked one controller with
its listener still attached.

Also guard `switch2page` on the `Rx<SettingsTabKey>` registration it actually
reads rather than only the `PageController` — now that both are really
deleted, a partial teardown would throw into the catch and silently open the
wrong tab — and re-check `mounted` after the await in the `_videoConnTimer`
tick, which `Timer::cancel` cannot stop once the body has started.

* refact: finish the plugin-framework removal sweep

#15854 removed the feature but stopped short of its leftovers:

- `Uninstall`, `Enable`, `Disable`, `Options` and `Please install plugins`
  were consumed only by the deleted `flutter/lib/plugin/**`; drop them from
  template.rs and the 50 locale files (250 dead entries). `Update` and
  `Install` stay, still used by desktop_home_page.dart.
- The server no longer sends `PrvOnFailedPlugin`, and the client no longer
  offers to install plugins when privacy mode fails to turn on.
- Drop the MSI `F_Client_Plugins` / `F_Server_Plugins` localization strings;
  no `.wxs` references them.
- `_DisplayMenu`'s constructor became a pure pass-through once `pluginItem`
  was removed, and the cfg inside `handle_input` repeats the one on the
  function itself.
- Normalize `src/lang/sl.rs` to 0644, the only executable file under src/.

6ad56075d6 Drag whole toolbar; snap to all four edges of the remote session window (#15051)
* Drag whole toolbar; snap to all four edges

Today the drag handle on the remote-session toolbar repositions only
the handle row -- the icons themselves stay centered at the top. This
change applies the position to the entire toolbar wrapper so dragging
the handle moves the whole thing, and extends snapping from top-only
to any of the four window edges.

When docked left/right the toolbar reflows vertically. A live ghost
preview shows where the toolbar will land while you drag, with a small
hysteresis bias to keep the preview from flickering near corners.

The legacy 'remote-menubar-drag-x' session option is read as a fallback
on first load so existing users keep their saved horizontal position;
new option keys are 'remote-menubar-edge' and 'remote-menubar-frac'.

Tested locally on Windows. macOS / Linux / web desktop use the same
shared widget with no platform-specific calls, but I did not verify
them.

* Load edge independently and clamp loaded fraction

Addresses CodeRabbit review on #15051: parse the saved edge regardless
of whether the new fraction option is present so a partial write of
frac doesn't reset the toolbar back to top, and clamp the loaded
fraction to the kOptionRemoteMenubarDragLeft/Right contract so a
corrupted or out-of-range saved value can't bypass the bounds until
the user drags again.

* Require edge activation zone to switch dock; preserve horizontal slide

Per review feedback on #15051: nearest-edge-wins made a low-intent
horizontal slide too easy to escalate into a high-impact orientation
change (vertical reflow on left/right dock). The default drag now
keeps the toolbar on its current dock edge and just updates the
fraction along that edge -- the prior horizontal-slide behavior.

An alternate edge is only previewed/committed when the cursor enters
its 32 px activation zone; once previewed, the cursor has to move
back 64 px before reverting (hysteresis at the zone boundary).

* Gate multi-edge docking behind a settings toggle; default = horizontal slide

Replaces the activation-zone approach with an explicit opt-in setting
in Settings -> Other ("Allow docking remote toolbar to any window
edge"). This addresses the concern that a low-intent horizontal drag
shouldn't be able to trigger a high-impact orientation change, while
still letting users who want multi-edge docking opt in cleanly.

Default (toggle off):
  - The original horizontal slide is preserved.
  - The bug fix from the first commit still applies: dragging the
    handle moves the whole toolbar, and the position persists across
    collapse/expand (no more re-center on re-open).
  - Draggable is axis-locked to horizontal so the feedback widget
    stays on the top line during drag.

Opt-in (toggle on):
  - Full nearest-edge wins with the live preview ghost and corner
    hysteresis; toolbar reflows vertically on left/right docks.
  - Draggable is unlocked for 2D drag.

Reads the option via mainGetLocalBoolOptionSync so the toolbar's
default state matches what the settings checkbox shows; the option
key uses the allow- prefix so unset defaults to off.

Takes effect on next session (setting is read at session init).

The setting key (allow-multi-edge-toolbar-dock) is read by the
existing local-options machinery and persists per-install without
needing to be registered in libs/hbb_common's KEYS_LOCAL_SETTINGS.
Can add that registration in a parallel hbb_common PR if preferred.

* Fix remote toolbar drag positioning & persistence

Align drag fraction calculation with the toolbar's actual travel range,
keep preview sizing stable during drag, and preserve legacy horizontal
position storage when multi-edge docking is disabled.
