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.
- 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.
* Added s_rem(s) for getting the remaining bytes in a stream
* Added s_rem_out() macro
* Fixed 15bpp pointer error checking
* Combined the 512 and 2048 bit certificate sending code paths
* Other detailed comments and logging added following MS-RDPBCGR
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.
Constants from MS documents (MS-RDPBCGR etc) moved out of
common/xrdp_constants.h into includes named after the documents.
Similar includes moved from sesman/chansrv to the common area.
remove not used chansrv <-> xrdp messages
move static channel disable control into libxrdp
remove some blocking read, write chansrv calls
add drdynvc calls to libxrdp
add drdynvc calls to chansrv
channel cleanup
In most cases, checking fd > 0 is not valid. open(2) returns -1 on
error, 0 on stdin, 1 on stdout, 2 on stderr, >2 . The border should be
between -1 and 0. Additionally, between 2 and 3.
