2014-04-22xfixes: Forbid manipulating clip for source-only pictures (#28968)Adam Jackson1-1/+1
Just throw BadPicture instead of crashing. It's not currently a meaningful thing to do anyway, RenderSetPictureRectangles would error if you tried (which this patch changes to BadPicture as well for consistency). The problem with trying to do it is if the clip is specified as a pixmap then we try to convert it to a region, and ->BitmapToRegion requires a ScreenPtr, and source-only pictures don't have one. I can imagine a use for client clip on source-only pictures, so if we really wanted to allow this, probably the way forward is to always store the clip as a region internally, and when setting the clip _from_ a pixmap, look up BitmapToRegion relative to the pixmap not the picture. But since clearly nobody can be relying on it working...

2012-03-21Introduce a consistent coding styleKeith Packard1-1908/+1876
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>

2009-10-01render: Fix crash in RenderAddGlyphs (#23645)Peter Hutterer1-1/+5
This patch fixes two bugs: size is calculated as glyph height * padded_width. If the client submits garbage, this may get above INT_MAX, resulting in a negative size if size is unsigned. The sanity checks don't trigger for negative sizes and the server goes and writes into random memory locations. If the client submits glyphs with a width or height 0, the destination pixmap is NULL, causing a null-pointer dereference. Since there's nothing to composite if the width/height is 0, we might as well skip the whole thing anyway. Tested with Xvfb, Xephyr and Xorg.
