2015-07-08Should use ErrorFSigSafe in OsSigHandlerJon TURNEY1-1/+1
2015-04-23Improve crashreportingJon TURNEY1-2/+2
Rather than invoking an external script to do crashreporting, load an optional DLL which contains the crashreporter. Use new interfaces in Cygwin 2.0.0 to extract EXCEPTION_POINTERS from the signal information, and pass those to the crashreporter.

2015-02-08Add crash reportingJon TURNEY1-0/+2
xorg_backtrace() is called in a few places to generate a backtrace for the log, when the condition is not fatal (mi queue overflow, vpnprintf unrecognized format), where we don't want to run the crash reporter So add a separate, explicit invocation of the crash reporter, which is invoked on a fatal signal only
2015-02-08Add -notrapsignalsJon TURNEY1-21/+28
Add -notrapsignals to disable catching of fatal signals (to either continue or log) and just use the default signal processing instead.

2013-11-11Trap SIGBUS to handle truncated shared memory segmentsKeith Packard1-0/+5
If a client passes a section of memory via file descriptor and then subsequently truncates that file, the underlying pages will be freed and the addresses invalidated. Subsequent accesses to the page will fail with a SIGBUS error. Trap that SIGBUS, figure out which segment was causing the error and then allocate new pages to fill in for that region. Mark the offending shared segment as invalid and free the resource ID so that the client will be able to tell when subsequently attempting to use the segment.

2012-07-09Reliably reset signals at server init timeKeith Packard1-0/+1
Each DDX currently calls OsReleaseSIGIO in case it was suspended when the server regen started. This causes a BUG to occur if SIGIO was *not* blocked at that time. Instead of relying on each DDX, make the OS layer reliably reset all signal state at server init time, ensuring that signals are suitably unblocked and that the various signal state counting variables are set back to zero.

While we probably don't need to be signal safe here since we will never return to the normal context, the logging signal context check will cause unsafe logging to be unhandled.

2012-03-21Introduce a consistent coding styleKeith Packard1-144/+141
This is strictly the application of the script 'x-indent-all.sh' from util/modular. Compared to the patch that Daniel posted in January, I've added a few indent flags: -bap -psl -T PrivatePtr -T pmWait -T _XFUNCPROTOBEGIN -T _XFUNCPROTOEND -T _X_EXPORT The typedefs were needed to make the output of sdksyms.sh match the previous output, otherwise, the code is formatted badly enough that sdksyms.sh generates incorrect output. The generated code was compared with the previous version and found to be essentially identical -- "assert" line numbers and BUILD_TIME were the only differences found. The comparison was done with this script: dir1=$1 dir2=$2 for dir in $dir1 $dir2; do (cd $dir && find . -name '*.o' | while read file; do dir=`dirname $file` base=`basename $file .o` dump=$dir/$base.dump objdump -d $file > $dump done) done find $dir1 -name '*.dump' | while read dump; do otherdump=`echo $dump | sed "s;$dir1;$dir2;"` diff -u $dump $otherdump done Signed-off-by: Keith Packard <keithp@keithp.com> Acked-by: Daniel Stone <daniel@fooishbar.org> Acked-by: Alan Coopersmith <alan.coopersmith@oracle.com>

Turns out, there's an initializer at the top of backtrace() that (on some arches) calls dlopen(). dlopen(), unsurprisingly, calls malloc(). So, call backtrace() early in signal handler setup so we can later safely call it from the signal handler itself.

2008-12-03Rework symbol visibility for easier maintenancePaulo Cesar Pereira de Andrade1-5/+5
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 Andrade1-5/+5
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()

OsInitColors always just returned TRUE, so just remove calls to it and insane special-case logic. Remove unused kcolor.c implementation, and merge oscolor.h into oscolor.c since it was the only user.
