- Fixes MSTSC resizing (with RFX as well).
- Queue system so that resizes are processed when XRDP and the X server
are ready, not immediately.
- Deletes and recreates the encoder (RFX fix)
- Introduces a dynamic_monitor_description struct that is used for the
queue system.
- Fix some lines previously introduced by the original resizing code to
be 80 chars long, as is the standard for XRDP.
While this feature is part of other branches for testing EGFX
integration, it somehow never made it into devel. This should fix
https://github.com/neutrinolabs/xrdp/issues/1928, for real this time!
The RFX compression mode requires an encoder. When you resize RFX, you
have to recreate the encoder.
This will fix it as well: https://github.com/neutrinolabs/xrdp/pull/2175,
however, that PR is bigger and more complex and may take longer.
Made session allocation policies more readable and maintainable.
The 'C' policy which was confusing before has been replaced with the
'Separate' keyword. This is a public interface change, but is unlikely
to affect many users.
The logging in session_get_bydata() is substantially improved, making
it far easier to spot why sessions are getting matched or not matched.
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.
Windows 10 RDS is quite relaxed about missing channel join PDUs,
whereas we have to adhere quite tightly to the specification to
make sure we get a TLS "Client hello" where appropriate. This makes
us incompatible with older RDP clients. For example, the Wyse sx0
thin client does not send a channel join PDU for the user channel.
Older, non-TLS versions of xrdp supported these devices.
This commit re-implements the xrdp v0.6.1 behaviour for non-TLS
connections only, allowing system administrators to use these devices
on trusted networks. These devices are in any case too old to
establish a modern TLS connection.
The Windows 10 RDS sets the user channel ID to be one more than the
ID of the last allocated static virtual channel. Currently we set it to
1002 (0x03ea) which is allocated to the server channel. This change
makes xrdp emulate RDS more closely.
The code in xrdp_mm.c to connect to chansrv over a TCP socket has
been removed, with the move to UDS. This PR simply removes the
chansrv TCP listening code. Without doing this, some configurations
result in a failure of xrdp to connect to chansrv.
