This commit allows a keycode_set to be specified as a module parameter
in xrdp.ini. This has the following effects:-
1) xrdp loads the specified keycode set for mapping RDP scancodes to
X11 keycodes. These are then passed to xorgxrdp as part of key press/
key release events.
2) The name of the XKB rules which use the specified keycode set are
passed to xorgxrdp so that XKB can be configured with rules which
match the chosen keycodes.
The effect is to remove all keycode set dependencies from xorgxrdp.
Normally evdev rules and evdev keycodes will be used but base rules and
base keycodes can be used instead for applications that require them.
Also, any systems which do not ship the evdev rules can be made to
work with base rules.
If the setting require_credentials is true, there should be no way
for the user to get to a login screen.
This commit makes the following changes if this flag is active:-
- Makes the checks around TS_INFO_PACKET more explicit.
- Closes the connection if the first login attempt fails.
On Linux, the TCP send buffer size is increased to 32768 if it is less
that this (which it normally is). This however has the effect of disabling
dynamic buffer sizing, leading to a maximum available bandwidth of
max_bandwidth = 262144 (bits) / round_trip_time (secs)
This is not noticeable on a LAN with an RTT of around 0.5ms, but
very noticeable on a WAN with an RTT of 0.25s.
Comments in the config file and manpage in this area are improved, as
is the logging if the parameters are actually set.
xrdp is updated to use the separate authenticate/authorization (AA) and
command processing interface now provided by sesman.
PAM processing has been removed entirely and moved into the seman PAM
module. As a result, gateway processing for proxy use-cases can be
made use of by non-PAM systems.
Since multiple processes can write logs simultaneously, and there
is no explicit synchronization between them, logs redirected to
stdout may interleave. When logging to the disk file, synchronization
is obtained by using a combination of O_APPEND and O_SYNC flags when
log file is being opened, which is not possible when <stdout>
redirection is in use.
So documentation is updated to cleanly notify that this is debug-only
feature, not for regular use
This commit adds the variables fv1_select and default_dpi to
xrdp.ini. These variables allow for a different font to be
loaded, depending on the DPI of the login screen.
This commit adds:
* replace multiple logging macros with LOG and LOG_DEVEL
* logging configuration for chanserv
* logging configuration for console output
* logging configuration for per file or method log level filtering for
debug builds
* file, line, and method name in log message for debug builds
