(cherry picked from commit 2c25e60abc5d080682d804fcbd25f9aee60fa2a1)
Disable clipboard_event_selection_request call is overkill for
blocking text/image/file purpose.
For example, it breaks existing behavior (slow response from gedit,
gimp as a side effects)
Instead, in clipboard_event_selection_request, these media format will
be blocked respectively which depends on the following configurations
in sesman.ini [Security] section.
* RestrictInboundClipboard=text
* RestrictInboundClipboard=file
* RestrictInboundClipboard=image
You can also set comma separated list.
* RestrictInboundClipboard=text,file,image
RestrictOutboundClipboard kills all of test/file/image
transfer via clipboard.
For controlling each content type behavior,
clipboard_xevent is not appropriate place to block respectively.
Instead, in clipboard_event_selection_notify, these media type
will be blocked which depends on the following configurations in
sesman.ini [Security] section.
* RestrictOutboundClipboard=text
* RestrictOutboundClipboard=file
* RestrictOutboundClipboard=image
You can also set comma separated list
* RestrictOutboundClipboard=text, file, image
It supports the extended configurations for sesman.ini:
Before:
[Security]
RestrictOutboundClipboard=true or false
After:
[Security]
RestrictInboundClipboard=[true or false | text or file or image | comma separated list]
RestrictOutboundClipboard=[true or false | text or file or image | comma separated list]
Above configuration is disabled by default (false)
And it can be specified comma separated list like this:.
RestrictInboundClipboard=file, image
RestrictOutboundClipboard=text, file, image
Note that if RestrictOutboundClipboard=true,file is set,
file is ignored and it is treated as RestrictOutboundClipboard=true
It is same for RestrictInboundClipboard.
According to https://github.com/neutrinolabs/xrdp/wiki/Logging,
it may be better to emit this log message because this log is
useful for system administrator to know whether RestrictOutboundClipboard
configuration works or not
And raise log level to info because it is informative for system
administrator.
As g_file_atom2 is x-special/gnome-copied-files
(See g_file_atom2 definition in sesman/chansrv/clipboard.c),
it should be "x-special/gnome-copied-files" in this context.
