One of the tests uses a child process which generates SIGSEGV.
On FreeBSD this generates a corefile by default which breaks
the 'make distcheck' process.
When xrdp is built with IPv6 support it will only fall back to IPv4 if
IPv6 is not supported (EAFNOSUPPORT). However, if the system is IPv6
capable but doesn't have an IPv6 address set (at least inside a FreeBSD
jail) EPROTONOSUPPORT is returned from socket().
When a resize is underway on a busy X server, it is possible for a
queued EGFX cmd (order #62) to be processed after the decoder has been
deleted. This causes a client disconnect with no useful error message.
g_strncpy() is the wrong function for copying strings in struct utmp[x]
as it always terminates strings.
strncpy() itself would be a good choice, but is marked by many compilers
as being unsafe to use.
str2memcpy() is taken from util-linux, and is exactly right for this
application.
POSIX.1 doesn't define ut_host in struct utmpx. Also, Linux has support
for an exit status value in ut_exit. This commit adds conditional code
for both ut_host and ut_exit to maximise portability.
- renamed the two files, including the header was conflicting with official headers
- configure look for utmp/utmpx headers, wo we know which struct to use
- reworked the usage for linux, works mostly (last still showing 'gone' for loggued users)
In GFX mode, if we're using xorgxrdp, frame updates are send directly
from the client, bypassing the screen buffer in xrdp_mm.
This commit only allows the xrdp_mm screen buffer to be invalidated
if the painter has drawn into it since the module was loaded. This
prevents the unused (and invalid) frame buffer being pushed to the client
in GFX mode with xorgxrdp.
Input message 300 to xorgxrdp which communicated a screen size
has been replaced with message 302 which sends a list of monitors
to xorgxrdp. This simplifies the initialisation and resize logic
somewhat, but a compatible version of xorgxrdp must be used
Significant updates for the VNC module:-
1) Support for the new API calls allowing both server and client
multi-monitor resizes.
2) The s member variable of the vnc_screen_layout structure is no longer
dynamically allocated.
3) The module server_width and server_height member variables are
removed as these are just duplicating server_layout.total_width and
server_layout.total_height.
4) When the server screens are resized, there is no need to restart the
entire resize state machine as we already know at this point that
the server supports resizing.
