This commit moves the '[Channels]' parsing code for xrdp.ini
from xrdp_wm_init() to an earlier location in xrdp_wm_create().
libxrdp can now check that drdynvc is not disabled before starting it,
and xrdp_wm can disable GFX if virtual channels are not available.
The responsibility for starting the drdynvc channel is moved out of
libxrdp into the application. This will make it easier to allow the
application to check the channel is enabled before starting it.
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
