Daniel Richard G 1c0c923ad1 Split g_file_open() into _ro() and _rw() variants 
Rename g_file_open() to g_file_open_rw(), and add a new g_file_open_ro()
call that wraps the common g_file_open_ex(file, 1, 0, 0, 0) idiom. This
will make the file access mode more explicit in the code.

Change all calls to g_file_open() to the _ro() or _rw() variant as
appropriate, and replace g_file_open_ex(file, 1, 0, 0, 0) with the _ro()
call.

Lastly, add tests for the two new calls to test_os_calls.c (code
courteously provided by matt335672).

matt335672 c5971b535d sesexec: Changes to existing files from sesman 
env.c : The value of XRDP_SESSION in the environment is now set to the
        PID of the sesexec process, which ties up the session with the
        output of "xrdp-sesadmin -c=list".

        Later versions of xrdp-sesadmin can use this value to get
        information about the current process.

matt335672 8e291846d5 Create pre-session list 
This is made from the old sesman_con structure. It describes
a connection to sesman which is not yet running a session.

matt335672 dadb393443 Add sesexec control module 
This module provides a secure way for sesman to start the sesexec program
and establish a private communications channel with it.

matt335672 3d95954d87 Move session_list to struct list * 
This commit now uses the standard list module to manage the active
session list, rather than having special code to do this.

matt335672 1a9d15bef0 Remove explicit auth_stop_session() call 
Now that authentication/authorization and session creation are
happening in the same process, there is no need for a separate call
to finish an auth session. This change prevents the upper software
layers from needing to track whether auth_start_session() has been
called or not.

matt335672 82ede29388 libsesman: Make x11_display_offset and max_sessions unsigned 2023-05-02 11:55:22 +01:00
matt335672 06580ec448 sesman config: Add MaxDisplayNumber 
When allocating a display number, we should be aware that
IANA only allow TCP displays up to :63. This PR adds that restriction in
to sesman.ini as a default, to prevent us allocating unavailable TCP
ports.

By default TCP ports are not enabled for X servers, but users can easily
change this if they wish to access X displays directly over the network.

This restriction is in addition to the MaxSessions limit already present
in sesman.ini

matt335672 e96d77bac1 Remove g_mk_socket_path() from codepaths 
The socket dir is only used if we are starting a session
with sesman. Consequently, it only makes sense to create
this directory within sesman itself.

Lennart Sauerbeck 5741653900 sesman: Prevent the use of 'alternate shell' 
By setting the new config value 'AllowAlternateShell' to 'no' it is now
possible to prevent the use of an alternate shell, which can be set by
the connecting user.
The default remains unchanged and any shell is allowed if the config
value is not specified. It can also be set explicitly to 'yes' to achieve
the same outcome.

Fixes: #850
