Fix a regression introduced in v0.10.x, where it became impossible to
connect to a VNC server which did not support the ExtendedDesktopSize
encoding.
(cherry picked from commit 6b25bdb7db487ff73152643815d55977d7a7efda)
The current code doesn't allow for an empty string to be pasted to the
clipboard on the X11 side. This is done by some lock screen programs
to prevent information leakage.
on connection, client IP and name are passed from xrdp to sesman to
sesexec, and then back to sesman again.
xrdp-sesadmin can now access the connection data from sesman
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.
This allows sesexec to send a reason for a connection close
request to xrdp.
xrdp is also updated to support server initiated disconnection sequences
from [MS-RDPBCGR] 1.3.1.4, along with reporting a reason to the client
for the disconnection.
Two problems were found:-
1) A useless test in scp_list.c - testing an unsigned int was >= 0.
2) Flow control issues in scp.c:scp_get_connect_session_response() meant
that file descriptors could be leaked. A helper function has been
used to simplify the code.
This allows the system administrator to specify whether the
reconnectwm.sh script should only be run on reconnects, or should
be run for all connections to a session.
The start session method is reworked to pass a response back to the
client.
If the method was successful, a session list entry is created. This
is different to the provious behaviour, where we created the
session list entry unconditionally.
This new arrangement means that we need a different way to avoid
a race condition where two users may try to create a session at the
same time, and end up with the same display. We do this by keeping
track of newly allocated displays as part of the SCP connections. When
we allocate a display, the SCP connection displays are also taken
into account.
This type can be used to store sets of integers. It is intended to
be used to keep track of the display numbers allocated to sessions and
SCP connections.
A test suite for the new type is also added.
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.
