* Update currentTime in dispatch loopUlrich Sibiller2019-09-291-0/+3
| | | | | | | | | | | | | | | | | | commit 312910b4e34215aaa50fc0c6092684d5878dc32f Author: Chase Douglas <chase.douglas@canonical.com> Date: Wed Apr 18 11:15:40 2012 -0700 Update currentTime in dispatch loop A request, like input device grabs, may check a request timestamp against currentTime. It is possible for currentTime to lag a previously sent event timestamp. If the client makes a request based on such an event timestamp, the request may fail the validity check against currentTime unless we always update the time before processing the request.

* nxagent: drop nxagentRootTileWindowUlrich Sibiller2019-08-271-2/+0
| | | | | | | | We either use a solid black or a white background and no backround pixmap. So nxagentRootTileWindow is always empty and we can drop all stuff around it. remove nxagentSplashCount, too, since it is no longer checked anywhere.
* rework xkb device private handlingUlrich Sibiller2019-06-221-0/+9
| | | | | | | We can only free the xkbDevicePrivate because we do not know the details of any other (possible) extension. So let's limit to that one private for now and call the new xkbFreePrivates from dix (where such a function is completely missing).

* CloseDevice: call XkbRemoveResourceClient before freeing key class structUlrich Sibiller2019-06-191-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | This patch is not necessary at the current code level. But when xkb code introduced the dev->key check Xorg upstream missed that. So we backport it now to skip that trap when updating xkb code. Author: Alan Coopersmith <alan.coopersmith@sun.com> Date: Mon Jan 4 18:21:54 2010 -0800 CloseDevice: call XkbRemoveResourceClient before freeing key class struct XkbRemoveResourceClient() returns immediately if dev->key is NULL. CloseDevice calls XkbRemoveResourceClient until it removes all resources. If we free dev->key and NULL it before XkbRemoveResourceClient, then infinite loop ensues, and the server appears to hang on exit or crash.

| | | | | | | | | CheckMotion() had been commented in add881931f2e702fb1952f4e1baba04b3dc536ee as it looked identical to the version from dix/events.c except for some commented code. But this based (probably) on a thinko - code that had been disabled by NX became active again this way. Fix this by removing the comments and by adding #ifdef/else to emphasize the difference.

This leads to weird behaviour for extensions that truly require running under the same OS services as the client, like MIT-SHM and DRI2. Add two new legal values for the initial connection's byteOrder field, 'r' and 'R'. These act like 'l' and 'B' respectively, but have the side effect of forcing the client to be treated as non-local. Forwarding proxies should attempt to munge the first packet of the connection accordingly; older servers will reject connections thusly munged, so the proxy should fall back to passthrough if the munged connection attempt fails.

However, the Popen code tears down and recreates the SIGALRM handler via OsSignal(), and this flag is dropped at this time. Clean the code to use just a single codepath for creating this signal handler, always applying SA_RESTART.

If process execution is inside certain blocking system calls when these signals arrive, e.g. with the kernel blocked on a contended semaphore, the system calls will be interrupted. Some system calls are automatically restartable (the kernel re-executes them with the same parameters once the signal handler returns) but only if the signal handler allows it. Set SA_RESTART on the signal handlers to enable this convenient behaviour.

Rather than doing this, just stop the timer before going into the select() portion of the WaitFor loop. It's a cheap system call, and it will only get called if there's no more commands batched up from the active fd. This change also allows some of the functions to be simplified; setitimer() will only fail if it's passed invalid data, and we don't do that... so make it void and remove all the conditional code that deals with failure. The change also allows us to remove a few variables that were used for housekeeping between the signal handler and the main loop. Signed-off-by: Keith Packard <keithp@koto.keithp.com> **Note**: The above change also required ABI changes in hw/nxagent/. commit abe0a51f3f790f8c055289465e130177c4b647cc Author: Ben Byer <bbyer@bbyer.apple.com> Date: Fri Sep 21 17:07:36 2007 -0700 So, like, checking return codes of system calls (signal, etc) is good.

Because our "popen" implementation uses stdio, and because nobody's stdio library is capable of surviving signals, we need to make absolutely sure that we hide the SIGALRM from the smart scheduler. Otherwise, when you open a menu in openoffice, and it recompiles XKB to deal with the accelerators, and you popen xkbcomp because we suck, then the scheduler will tell you you're taking forever doing something stupid, and the wait() code will get confused, and input will hang and your CPU usage slams to 100%.
