This name better matches the name from [MS-RDPBCGR]. Also, the size
of the UTF-8 buffer allocated for the client name is not large
enough for some of the names which could potentially be passed across
in UTF-16 from the client.
The data in 'struct xrdp_client_info' which is shared with xorgxrdp
is separated out into a separate structure. This makes it simpler to
change 'struct xrdp_client_info' without affecting xorgxrdp.
1) In FIPS mode, Classic RDP security is not allowed at all.
2) In FIPS mode xrdp-keygen creates an empty file
3) Documentation wording improved around the security_level setting
4) Logging improved around the security negotiation
5) Warnings now generated if Classic RDP security is negotiated
This commit allows a keycode_set to be specified as a module parameter
in xrdp.ini. This has the following effects:-
1) xrdp loads the specified keycode set for mapping RDP scancodes to
X11 keycodes. These are then passed to xorgxrdp as part of key press/
key release events.
2) The name of the XKB rules which use the specified keycode set are
passed to xorgxrdp so that XKB can be configured with rules which
match the chosen keycodes.
The effect is to remove all keycode set dependencies from xorgxrdp.
Normally evdev rules and evdev keycodes will be used but base rules and
base keycodes can be used instead for applications that require them.
Also, any systems which do not ship the evdev rules can be made to
work with base rules.
- xrdp is not now built with XRDP_IBUS to allow other input
methods to be more easily supported.
- chansrv is only aked to start an input method if the client
supports it.
- chansrv sends a status report back to xrdp when asked to start
and input method.
- ./configure without --enable-ibus now works.
* Store EGFX state before entering resize state machine
At present the EGFX state is destroyed by states WMRZ_EGFX_DELETE_SURFACE
through WRMZ_EGFX_DELETE. This means that at WMRZ_EGFX_INITIALIZE we
cannot distinguish between EGFX not being ever used, and EGFX
having been torn down. Consequently, when running non-GFX, we don't
correctly recover the session.
* Allow multiple reasons for suppress_output
Replaces the single boolean for suppress_output with
a bitmask, to allow output to be suppressed for
more than one reason
* Disable output during resize
* Add states to dynamic resize
Adds states to the dynamic resize state machine so we wait for a
Deactivation-Reactivation sequence to finish before sending pointer
updates, etc.
* suppress module output during the dynamic resize
* Add support for dynamic resize to VNC backend
xrdp_mm needs to be informed when a resize has been performed so that
the resize stte machine can be updsate.
- Mostly base functions and utilities necessary to enable RFX
Progressive
- Add more EGFX work & mode flags.
- Update encoder.
- Does not yet include caps determination to enable RFX progressive
(yet).
- Update protocol constants
To implement a scalable login screen, we need to be able to ascertain
the DPI of the connected primary monitor.
At present, in a multi-monitor situation, this information is available in
the struct display_size_description, which can be searched for the primary
monitor. This is only the case however if the Display Control Channel
Extension is in use ([MS-RDPEDISP]), and a DISPLAYCONTROL_MONITOR_LAYOUT
has been received.
This PR retrieves physical monitor size information from the following
two additional places.
1) The TS_UD_CS_CORE PDU. Physical size information is optionally
included in this PDU for single-screen configurations.
2) The TS_UD_CS_MONITOR_EX PDU. This includes physical size
information for multiple-screen configurations.
The connected client is currently described in two places in
the xrdp_client_info structure:-
1) In the connection_description field. This was introduced as
field client_ip by commit d797b2cf49
for xrdp v0.6.0
2) In the client_addr and client_port fields introduced by commit
25369460a1 for xrdp v0.8.0
This commit unifies these two sets of fields into a single
set of fields describing the connection IP and port (for
AF_INET/AF_INET6 connections only) and a connection description
for all connection types.
The code in os_calls to provide client logging has been simplified
somewhat which should make it easier to add new connection types (e.g.
AF_VSOCK).
The old connection_description field used to be passed to sesman to
inform sesman of the IP address of the client, and also to provide
a string for 'C' field session policy matching. 'C' field session policy
matching does not actually need this string (see #2239), and so now only
the IP field is passed to sesman.
- Eliminate duplicaiton for display_size_description
- monitorCount needs to be uint32_t
- width/height -> session_width/session_height
- Update CLIENT_INFO_CURRENT_VERSION
- Also some misc unit test updates.
- Minor log updates.
There are two places where monitor descriptions are passed through the
RDP protocol:
- TS_UD_CS_MONITOR ([MS-RDPBCGR] 2.2.1.3.6 Client Monitor Data)
- DISPLAYCONTROL_PDU_TYPE_MONITOR_LAYOUT ([MS-RDPEDISP] 2.2.2.2)
The processing logic for both of them is similar enough that they should be unified.
Also update to define the constants for the maximum and minimum desktop width/height for monitors and total area.
Also a large number of clarifications for the constants and protocol
requirements.
Note that this is also the first step to making resizing work with the extension GFX channel as well as an important
foundational step to enable HiDPI compatibility.
Also some misc logging updates.
- Based on https://github.com/jsorg71/xrdp/tree/dynamic_monitor
- Tested with xorgxrdp
- Tested with vnc
- Only works with single monitor.
- Update documentation to clarify the difference between MSTSC and
Microsoft Remote Desktop.
- Does not include compatibility with /gfx at this time, which is still
in testing.
- Updates to include ms-rdpedisp.h header for the 2.2.2 specification of
the protocol.
- Adds new dynamic_monitor_layout struct that shares the number of
monitors with xrdp_client_info.h
- Does not allow for BPP changes because the RDP protocol doesn't
support it.
- Option to disable feature as NeutrinoRDP doesn't support it (It was
based on FreeRDP 1.0.1 which didn't yet have this feature.)
- Add CLIENT_MONITOR_DATA_MAXIMUM_MONITORS constant and reference
spec definition.
Depends on https://github.com/neutrinolabs/xorgxrdp/pull/183
If a server is multihomed (i.e. mutiple domains) the
users are identified by their domain name. This change
allows to concat the domain name to the username with
a specific separator.
This feature allows to embed a token in the username field. Tokens
are separated from the username by the ASCII field separator character
0x1F (unicode 0x001F).
The MS specs determine that the character buffer lenngths
for usernames, domains, passwords, alternate shells, etc
can be up to 512 characters including the mandatory null
terminator.
