* 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.

* Keyboard.c: nullify freed pointersUlrich Sibiller2019-06-191-7/+11
| | | | | | | While trying to properly free memory allocated by XKB I accidently called nxagentFreeKeyboardDeviceData twice and noticed it would cause a segfault here. As the other pointers are also nullified after being freed let's just do it here, too.
* Screen.c: Fix: make sure RRCloseScreen is being calledUlrich Sibiller2019-06-191-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes ArcticaProject/nx-libs#598 In nxagentOpenScreen we first initialized the RRExtension for the screen and then replaced pScreen->CloseScreen by nxagentCloseScreen. This resulted in RandR's RRCloseScreen (and any other CloseScreen procedure installed by extensions) being no longer called. Moving RandR init after configuring pScreen->CloseScreen ensures the correct calling cascade: RRCloseScreen -> nxagentCloseScreen ->fbCloseScreen (called explicitly by nxagentCloseScreen). Which in turn will fix this memory leak: ==9688== 328 (312 direct, 16 indirect) bytes in 1 blocks are definitely lost in loss record 271 of 319 ==9688== at 0x4837B65: calloc (vg_replace_malloc.c:752) ==9688== by 0x4ED2C6: RRScreenInit (randr.c:329) ==9688== by 0x1F2B18: nxagentInitRandRExtension (Extensions.c:122) ==9688== by 0x1DEAFF: nxagentOpenScreen (Screen.c:1409) ==9688== by 0x16D7F8: AddScreen (dispatch.c:4257) ==9688== by 0x1DA0CF: InitOutput (Init.c:397) ==9688== by 0x14DCC2: main (main.c:280)

* Window.c: Drop defines CWParent and CWStackingOrderUlrich Sibiller2019-06-122-17/+14

| | | | | | | | | | | This was eventually replaced by nxagentAddConfiguredWindow(pWin, CW_Map) some lines below which is just leading to the same code being executed some time later. (nxagentAddConfiguredWindow() will add a window to a list. nxagentFlushConfiguredWindow() is called at certain points to update all windows in that list in one go. "update" here means calling XConfigureWindow() or XMapWindow() on the real display.)

As these also should be in upstream code we add them there (Note: Xorg never fixed this but totally rewrote the miPaintWindow() later on.) This allows us to totally drop our special version of miPaintWindow().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not sure how it came to this situation, but the following commit is partly contained in our version of the code. Some lines had not been removed, tough... commit c80c41767eb101e9dbd8393d8cca7764b4e248a4 Author: Aaron Plattner <aplattner@nvidia.com> Date: Mon Oct 25 22:01:32 2010 -0700 os: Fix BigReq ignoring when another request is pending Commit cf88363db0ebb42df7cc286b85d30d7898aea840 fixed the handling of BigReq requests that are way too large and handles the case where the read() syscall returns a short read. However, it neglected to handle the case where it returns a long read, which happens when the client has another request in the queue after the bogus large one. Handle the long read case by subtracting the smaller of 'needed' and 'gotnow' from oci->ignoreBytes. If needed < gotnow, simply subtract the two, leaving gotnow equal to the number of extra bytes read. Since the code immediately following the (oci->ignoreBytes > 0) block tries to handle the next request, advance oci->bufptr immediately instead of setting oci->lenLastReq and letting the next call to ReadRequestFromClient do it. Fixes the XTS pChangeKeyboardMapping-3 test.

| | | | | | | | | 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.
