2017-03-01dispatch: Mark swapped dispatch as _X_COLDAdam Jackson1-1/+1
This touches everything that ends up in the Xorg binary; the big missing part is GLX since that's all generated code. Cuts about 14k from the binary on amd64. Signed-off-by: Adam Jackson <ajax@redhat.com> Reviewed-by: Eric Anholt <eric@anholt.net>

2015-04-21Let calloc handle multiplicationAlan Coopersmith1-2/+2
It's going to multiply anyway, so if we have non-constant values, might as well let it do the multiplication instead of adding another multiply, and good versions of calloc will check for & avoid overflow in the process.

2014-12-08Xi: unvalidated lengths in Xinput extension [CVE-2014-8095]Alan Coopersmith1-0/+2
Multiple functions in the Xinput extension handling of requests from clients failed to check that the length of the request sent by the client was large enough to perform all the required operations and thus could read or write to memory outside the bounds of the request buffer. This commit includes the creation of a new REQUEST_AT_LEAST_EXTRA_SIZE macro in include/dix.h for the common case of needing to ensure a request is large enough to include both the request itself and a minimum amount of extra data following the request header.

2012-07-09Remove unneccesary casts from WriteToClient callsAlan Coopersmith1-1/+1
Casting return to (void) was used to tell lint that you intended to ignore the return value, so it didn't warn you about it. Casting the third argument to (char *) was used as the most generic pointer type in the days before compilers supported C89 (void *) (except for a couple places it's used for byte-sized pointer math).

XInput 2.1 and earlier clients do not know about touches. We must report touch emulated button presses for these clients. For later clients, we only report true pointer button presses.

2012-03-21Introduce a consistent coding styleKeith Packard1-37/+26
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>
2011-11-09input: replace remaining GetPairedDevice() with GetMaster()Peter Hutterer1-1/+1

2011-02-22Switch to use IsFloating()Peter Hutterer1-1/+1
This is not a straightforward search/replacement due to a long-standing issue. dev->u.master is the same field as dev->u.lastSlave. Thus, if dev is a master device, a check for dev->u.master may give us false positives and false negatives. The switch to IsFloating() spells out these cases and modifies the conditions accordingly to cover both cases.

2010-06-03Move each screen's x/y origin into ScreenRec.Jamey Sharp1-4/+5
Many references to the dixScreenOrigins array already had the corresponding screen pointer handy, which meant they usually looked like "dixScreenOrigins[pScreen->myNum]". Adding a field to ScreenRec instead of keeping this information in a parallel array simplifies those expressions, and eliminates a MAXSCREENS-sized array. Since dix declared the dixScreenOrigins array, I figure allocating a screen private for these values is overkill.

The only remaining X-functions used in server are XNF*, the rest is converted to plain alloc/calloc/realloc/free/strdup. X* functions are still exported from server and x* macros are still defined in header file, so both ABI and API are not affected by this change.
