2011-05-02Clean up memory better when GetVisualInfo fails in ProcDbeGetVisualInfoAlan Coopersmith1-14/+11
Use calloc to initialize pScrVisInfo array so we don't have to check which ones were already initialized when freeing them all. On failure, set rc if necessary, and jump to code at end that already frees all the necessary allocations and return rc. Fixes parfait reported error: Error: Memory leak (CWE 401) Memory leak of pointer 'pScrVisInfo' allocated with malloc((count * 16)) at line 724 of dbe/dbe.c in function 'ProcDbeGetVisualInfo'. 'pScrVisInfo' allocated at line 693 with malloc((count * 16)). pScrVisInfo leaks when rc != 0 at line 710 and j >= i at line 716. [ This bug was found by the Parfait 0.3.7 bug checking tool.

2010-07-02miDbe window priv priv is pre-allocated, don't use dixSetPrivate (bug 28639)Keith Packard1-6/+0
miDbeInit pre-allocates space in each DBE window private private for a MiDbeWindowPrivPrivRec. miDbeAllocBackBufferName used the pre-allocated space correctly (simply fetching it instead of allocating a new piece of memory). However, it then called dixSetPrivate anyways, which isn't necessary, and (in the new dixPrivate world) causes an assert failure.

2010-06-05Remove dixRegisterPrivateOffset; hard-code devPrivates offsets insteadKeith Packard1-4/+0
For predefined resource types, the offset of the devPrivates field was already kept in a constant table. The only non-predefined type needing this treatment was dbeDrawableResType, which is just a magic alias for RT_PIXMAP. This patch special-cases looking up RC_DRAWABLE offsets and uses the table directly for everything else. Signed-off-by: Keith Packard <keithp@keithp.com> Reviewed-by: Jamey Sharp <jamey@minilop.net>
2010-06-02Fix pixmap validation in miDbePositionWindow.Aaron Plattner1-6/+14
miDbePositionWindow allocates two pixmaps: a front buffer, and a back buffer. If the buffers are supposed to be initialized, it validates a GC against the front buffer, then uses it to fill and/or copy both the front buffer *and* the back buffer, without revalidating. If the acceleration architecture needs different GC funcs for the two pixmaps -- for example if allocation of the front buffer exhausted video memory -- then this can cause crashes because the GC is not validated for the back buffer pixmap. Fix this by performing the rendering for the front buffer first, then revalidating against the back buffer before performing the back buffer rendering.

A grep on xorg/* revealed there's no consumer of this define. Quote Alan Coopersmith: "The consumer was in past versions of the headers now located in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h, all the event definitions were only available if NEED_EVENTS were defined, and all the reply definitions required NEED_REPLIES. Looks like Xproto.h dropped them by X11R6.3, which didn't have the #ifdef's anymore, so these are truly ancient now."

2008-12-03Rework symbol visibility for easier maintenancePaulo Cesar Pereira de Andrade2-2/+2
Save in a few special cases, _X_EXPORT should not be used in C source files. Instead, it should be used in headers, and the proper C source include that header. Some special cases are symbols that need to be shared between modules, but not expected to be used by external drivers, and symbols that are accessible via LoaderSymbol/dlopen. This patch also adds conditionally some new sdk header files, depending on extensions enabled. These files were added to match pattern for other extensions/modules, that is, have the headers "deciding" symbol visibility in the sdk. These headers are: o Xext/panoramiXsrv.h, Xext/panoramiX.h o fbpict.h (unconditionally) o vidmodeproc.h o mioverlay.h (unconditionally, used only by xaa) o xfixes.h (unconditionally, symbols required by dri2) LoaderSymbol and similar functions now don't have different prototypes, in loaderProcs.h and xf86Module.h, so that both headers can be included, without the need of defining IN_LOADER. xf86NewInputDevice() device prototype readded to xf86Xinput.h, but not exported (and with a comment about it).
2008-11-29Export symbols defined in the sdk.Paulo Cesar Pereira de Andrade1-1/+1
This is the biggest "visibility" patch. Instead of doing a "export" symbol on demand, export everything in the sdk, so that if some module fails due to an unresolved symbol, it is because it is using a symbol not in the sdk. Most exported symbols shouldn't really be made visible, neither advertised in the sdk, as they are only used by a single shared object. Symbols in the sdk (or referenced in sdk macros), but not defined anywhere include: XkbBuildCoreState() XkbInitialMap XkbXIUnsupported XkbCheckActionVMods() XkbSendCompatNotify() XkbDDXFakePointerButton() XkbDDXApplyConfig() _XkbStrCaseCmp() _XkbErrMessages[] _XkbErrCode _XkbErrLocation _XkbErrData XkbAccessXDetailText() XkbNKNDetailMaskText() XkbLookupGroupAndLevel() XkbInitAtoms() XkbGetOrderedDrawables() XkbFreeOrderedDrawables() XkbConvertXkbComponents() XkbWriteXKBSemantics() XkbWriteXKBLayout() XkbWriteXKBKeymap() XkbWriteXKBFile() XkbWriteCFile() XkbWriteXKMFile() XkbWriteToServer() XkbMergeFile() XkmFindTOCEntry() XkmReadFileSection() XkmReadFileSectionName() InitExtInput() xf86CheckButton() xf86SwitchCoreDevice() RamDacSetGamma() RamDacRestoreDACValues() xf86Bpp xf86ConfigPix24 xf86MouseCflags[] xf86SupportedMouseTypes[] xf86NumMouseTypes xf86ChangeBusIndex() xf86EntityEnter() xf86EntityLeave() xf86WrapperInit() xf86RingBell() xf86findOptionBoolean() xf86debugListOptions() LoadSubModuleLocal() LoaderSymbolLocal() getInt10Rec() xf86CurrentScreen xf86ReallocatePciResources() xf86NewSerialNumber() xf86RandRSetInitialMode() fbCompositeSolidMask_nx1xn fbCompositeSolidMask_nx8888x0565C fbCompositeSolidMask_nx8888x8888C fbCompositeSolidMask_nx8x0565 fbCompositeSolidMask_nx8x0888 fbCompositeSolidMask_nx8x8888 fbCompositeSrc_0565x0565 fbCompositeSrc_8888x0565 fbCompositeSrc_8888x0888 fbCompositeSrc_8888x8888 fbCompositeSrcAdd_1000x1000 fbCompositeSrcAdd_8000x8000 fbCompositeSrcAdd_8888x8888 fbGeneration fbIn fbOver fbOver24 fbOverlayGeneration fbRasterizeEdges fbRestoreAreas fbSaveAreas composeFunctions VBEBuildVbeModeList() VBECalcVbeModeIndex() TIramdac3030CalculateMNPForClock() shadowBufPtr shadowFindBuf() miRRGetScreenInfo() RRSetScreenConfig() RRModePruneUnused() PixmanImageFromPicture() extern int miPointerGetMotionEvents() miClipPicture() miRasterizeTriangle() fbPush1toN() fbInitializeBackingStore() ddxBeforeReset() SetupSprite() InitSprite() DGADeliverEvent() SPECIAL CASES o defined as _X_INTERNAL xf86NewInputDevice() o defined as static fbGCPrivateKey fbOverlayScreenPrivateKey fbScreenPrivateKey fbWinPrivateKey o defined in libXfont.so, but declared in xorg/dixfont.h GetGlyphs() QueryGlyphExtents() QueryTextExtents() ParseGlyphCachingMode() InitGlyphCaching() SetGlyphCachingMode()
