* Use $XDG_STATE_HOME for known hosts storagePierre Ossman2024-05-303-4/+8
| | | | | This is an often changed database, so it is better suited for $XDG_STATE_HOME rather than the more static $XDG_DATA_HOME.
* Only do restorecon() for legacy directoryPierre Ossman2024-05-301-12/+12
| | | | | This is only needed because of an historical type change of the legacy directory, so avoid doing it anywhere else.
* Fix late vncsession loggingPierre Ossman2024-05-301-0/+7
| | | | | | | | | The syslog file descriptor will be closed when we are cleaning up in preparation for running the vncserver script, so we need to explicitly reopen things in case we need to log errors. At the same time, try to be polite and explicitly close the log when appropriate.
* Respect PAM modules for $XDG_STATE_HOMEPierre Ossman2024-05-301-3/+16
| | | | | E.g. pam_env.so might modify this variable, so we should see what we get out of PAM when building a log file path.
* Add comment that PAM configuration is an examplePierre Ossman2024-05-201-0/+4
| | | | | | There is too much variation between distributions for us to have a good PAM configuration that works everywhere. Try to make this more obvious by having a comment at the top of the file.

| | | | | | | | | | | | | | | | Specifies that the server must ignore all keyboard or mouse events sent by the client. Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2180903 Signed-off-by: Carlos Santos <casantos@redhat.com>

| * Move the AccessRights type and constants to the rfb namespaceCarlos Santos2024-04-2317-60/+116
| | | | | | | | | | | | | | | | | | They must belong to the rfb namespace, not to the SConnection class. Also add an AccessNone constant, since it's better to use a mnemonic symbol rather than zero to initialize the accessRights members. Signed-off-by: Carlos Santos <casantos@redhat.com>
* | Don't check pointers for zero length buffersPierre Ossman2024-05-202-4/+4
| | | | | | | | | | It's perfectly fine to give a NULL pointer if the length has explicitly been specified as zero.

| | | | | | | | | | | | | | | | | | The norm is that the install target is read only from the point of view of the source and build directory, so avoid accidentally triggering any build.

* | Use XQueryPointer() instead to detect zaphodPierre Ossman2024-04-101-4/+8
| | | | | | | | | | | | FLTK can send events with fl_xevent pointing to random memory, which means that we cannot trust that structure. XQueryPointer() can give us what we need, at the cost of an extra round trip.

* Don't link gcrypt for static GnuTLSPierre Ossman2024-03-151-5/+0
| | | | | | GnuTLS seems to have dropped grypt support ages ago, so let's not confuse things by assuming it might be needed when linking GnuTLS statically.
* Properly propagate CursorWarpedTo()Pierre Ossman2024-03-141-0/+5
| | | | | Although unlikely, there might be other parts of the X server that are also interested in this call. Make sure we propagate things on properly.

| | | | | It doesn't just control button events, but all types of pointer events, including movement.
* Fix shared memory leakAdam Halim2024-01-261-1/+1
| | | | | | | | The MIT-SHM documentation: https://www.x.org/releases/X11R7.7/doc/xextproto/shm.html says to run XShmDetach() first, and then to destroy the segment. (cherry picked from commit 585ee24d4cd81759ca7206d5d5181a491c2e8898)
* Increase time required to override pointerClientSamuel Mannehed2024-01-261-1/+1
| | | | | | | | | | | | | | | | | | Mouse events in shared connections are locked to one viewer at a time. If the a mouse drag is happening in the first viewer, the second viewer can't interfere unless the first viewer has been inactive for a set amount of time. This timeout was put in place in 71c83b479335337b25dc331d3fb4a6e29382ceb5 to handle the case where the first viewer disconnects while the mouse drag is happening. Prior to the timeout, this resulted in all input being blocked. This commit increases this timeout from 3 seconds to 10 seconds. This is to minimize the risk of this happening during "normal" use. With this change, the first viewer has to be inactive for 10 seconds before the second viewer can take control again. In the case where the first viewer disconnects, a waiting time of 10 seconds for the second viewer seems very reasonable.

|\ | | | | VNCServerST: Add a timeout to pointer button ownership
| * VNCServerST: Add a timeout to pointer button ownershipMike Looijmans2024-01-222-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When one clients holds down a button on the pointer device (probably dragging something), other clients' attempts at pointer operations are denied. This yields a sane user experience, but with limits. When one clients starts dragging, and then his network connection fails, other clients are denied access to the pointer until the VNC server finally discovers that the connection is dead and closes it. This can take about 15 minutes. Add a timeout to this policy: If we don't hear from the client for 3 seconds, other clients are allowed to control the pointer once more. This solves the problem that one failing network could make the server completely deaf to other clients for a long time. Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl>

| * Allow combining socket activation and extra portsPierre Ossman2024-01-242-36/+50
| | | | | | | | | | | | The common use case is probably to only listem to the systemd provided socket when using socket activation, but it might not be the only use case. Make sure things can be combined if explicitly requested.

| * x0vncserver: Add support for systemd socket activationMike Looijmans2024-01-124-29/+65
| | | | | | | | | | | | | | | | | | | | systemd can pass in sockets as file descriptors 3 and beyond. Allows the server to use socket activation. When triggered by systemd, no other listening sockets (e.g. rfbport) will be activated. Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl>
* | VNCSConnectionST: Release mouse button(s) on closeMike Looijmans2024-01-151-0/+3
|/ | | | | | | | | | | | | | | | | | | | | When the connection is severed, release all mouse buttons. This fixes an issue with x0vncserver where the local display would stop responding to mouse events if the connection closes while the remote user was holding down a mouse button. To reproduce, start a VNC client, press and hold a mouse button and then kill the connection (e.g. close client, kill server, yank network cable). This caused the local screen to no longer respond to any mouse-down events until a VNC client reconnects and clicks anywhere. This may inject a "mouse release" event while closing, however, if you click on your screen and then yank the mouse cable, a mouse release event also would not come unexpectedly, so the cure's side effects aren't as bad as the disease.
