2010-02-17os: Prevent core dump from being truncated.Rami Ylimaki2-6/+6
The problem fixed by this patch can be reproduced on Linux with the following steps. - Access NULL pointer intentionally in ProcessOtherEvent on key press. - Instead of saving core dump to a file, write it into a pipe. echo "|/usr/sbin/my-core-dumper" > /proc/sys/kernel/core_pattern - Dump the core by pressing a key. While the core is being dumped into the pipe, the smart schedule timer will cause a pending SIGALRM. Linux kernel stops writing data to the pipe when there are pending signals. This causes the core dump to be truncated. On my system I'm expecting a 6 MB dump but the size will be 60 kB instead. The problem is solved if we block the SIGALRM caused by expired smart schedule timer. I haven't been able to reproduce this problem in the following cases. - Save core dump to a file instead of a pipe. - kill -SEGV `pidof Xorg` - Press a key to dump core while gdb is attached to Xorg. - Give option -dumbSched to Xorg. Also note that the fix works only when NoTrapSignals has the default value FALSE. The problem can still be reproduced if error signals aren't trapped. In addition to pending SIGALRM, there is a similar problem with pending SIGIO from the keyboard driver during core dump.

2009-10-13Rootless: Abstract some of the Xplugin specific stuff which has crept into ↵Jeremy Huddleston5-68/+26
rootlessWindow.c The rootless extension now directly calls some Xplugin functions, and relies on types defined in Xplugin.h, which isn't very abstracted :-) This patch is a start at abstracting some of the Xplugin specific stuff which has crept into rootlessWindow.c. This has been done in a pretty mindless fashion, without much thought as to if the additions to the generic rootless interface are the correct ones There is some confusion as to if RootlesscolormapCallback() returns a Bool or xp_error_enum value (not so abstact), but I have no way of checking, of finding out if Xplugin actually checks the result :-) Based on patches from Colin Harrison, Jon Turney and Yaakov Selkowitz Signed-off-by: Jon TURNEY <jon.turney@dronecode.org.uk> Signed-off-by: Jeremy Huddleston <jeremyhu@freedesktop.org> Signed-off-by: Keith Packard <keithp@keithp.com>

2008-12-10Add dependency tracking to sdksyms.c and export composite wrapper.Paulo Cesar Pereira de Andrade1-8/+8
Thanks to David Miller for noticing a make problem with sdksyms.c not being regenerated when sdksyms.sh is updated. This is not yet the best solution; automake generates dependency for sdksyms.o, but the build really should also regenerate sdksyms.c when sdksyms.o needs to be regenerated. Export the symbols in miext/cw/cw.h. These symbols are in libxaa, and at least the nvidia driver uses them. Maybe cw.h should be installed in the sdk.
2008-12-03Rework symbol visibility for easier maintenancePaulo Cesar Pereira de Andrade10-75/+75
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).
2008-12-02Add visibility flags to XSERVER_CFLAGS.Paulo Cesar Pereira de Andrade1-1/+1
This is done to actually change DIX_CFLAGS, as not all "modules" use XORG_CFLAGS. Also export the symbols that are required by other modules after the change.
2008-11-30Remove declarations of symbols that are never defined.Paulo Cesar Pereira de Andrade1-3/+0
These symbols were removed from the X Server, or never declared. One symbol that may need special attention is XkbBuildCoreState(), that doesn't have a prototype anywhere, but is called from xkb/xkbEvents.c:XkbFilterEvents(), and also used by the macros XkbStateFieldFromRec() and XkbGrabStateFromRec() defined in include/xkbstr.h. fb/wfbrename.h also may need some cleanup, as it makes several "renames" of non existing symbols.
2008-11-29Export symbols defined in the sdk.Paulo Cesar Pereira de Andrade7-22/+25
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()

2008-08-30damage: initial attempt at a damage marker mechanismMaarten Maathuis3-12/+107
- This should allow drivers to recieve post submission events for X<->opengl synchronisation. - Lacking a testcase, i'm open to suggestion how to do it better. - The idea is: - driver recieves event - driver creates personal identification and inserts marker into X fifo. - when something wants to use an X pixmap, it checks if something is pending. - If so, it synchronizes the 2nd fifo using the initial identification. - Driver is not required to use interrupt based systems (price too high). - Lower latency is ofcource better. - If this is somehow unusable for you, then come up with improvements. - For that reason i wouldn't consider the api fixed for the moment.
