* Fix negotiation in stage 10 errorVadim Troshchinskiy2015-09-281-1/+37
| | | | | Problem fixed by adding a select() call to implement a timeout, and retrying writes if needed.
* use xfree instead of free for xalloced dataUlrich Sibiller2015-09-262-3/+3
| | | | | This was brought in by a backport since in later versions xalloc/xfree have been replaced by malloc/free.

| | | | | | | | The lastSetTime value which indicates when the configuration within the server was last changed was not getting set in the appropriate RandR requests. Signed-off-by: Keith Packard <keithp@keithp.com>
* Backport: randr: Clean up compiler warnings about unused and shadowing variablesKeith Packard2015-06-073-21/+5
| | | | | | | | | | | | set but not used variables shadowing a previous local A hidden problem was that the VERIFY_RR_* macros define local 'rc' variables, any other local definitions for those would be shadowed and generate warnings from gcc. I've renamed the other locals 'ret' instead of 'rc'. Signed-off-by: Keith Packard <keithp@keithp.com>
* Backport: randr: Fix REQUEST vs. REQUEST_SIZE_MATCH mismatchAaron Plattner2015-06-071-1/+1
| | | | | | | | | | | ProcRRGetScreenSizeRange uses REQUEST(xRRGetScreenSizeRangeReq) followed by REQUEST_SIZE_MATCH(xRRGetScreenInfoReq). This happens to work out because both requests have the same size, so this is not a functional change, just a cosmetic one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The length checking code validates PutImage height and byte width by making sure that byte-width >= INT32_MAX / height.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ProcPutImage() calculates a length field from a width, left pad and depth specified by the client (if the specified format is XYPixmap). The calculations for the total amount of memory the server needs for the pixmap can overflow a 32-bit number, causing out-of-bounds memory writes on 32-bit systems (since the length is stored in a long int variable). v2: backport to nx-libs 3.6.x (Mike DePaulo) v3: port to NXdispatch.c rather than dispatch.c (Mike DePaulo) Reported-by: Ilja Van Sprundel <ivansprundel@ioactive.com> Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com> Reviewed-by: Peter Hutterer <peter.hutterer@who-t.net> Conflicts: dix/dispatch.c

|/ | | | | | | | | | | | | | | | | | | | | | | xorg/Xserver http://lists.x.org/archives/xorg-announce/2013-October/002332.html Save a pointer to the passed in closure structure before copying it and overwriting the *c pointer to point to our copy instead of the original. If we hit an error, once we free(c), reset c to point to the original structure before jumping to the cleanup code that references *c. Since one of the errors being checked for is whether the server was able to malloc(c->nChars * itemSize), the client can potentially pass a number of characters chosen to cause the malloc to fail and the error path to be taken, resulting in the read from freed memory. Since the memory is accessed almost immediately afterwards, and the X server is mostly single threaded, the odds of the free memory having invalid contents are low with most malloc implementations when not using memory debugging features, but some allocators will definitely overwrite the memory there, leading to a likely crash. v2: Apply to NXdixfonts.c rather than dixfonts.c (Mike DePaulo)

This involves creating a new API call void NXTransCleanupForReconnect(void); which basically cleans up the global state for the connection but does not exit the process. Background ========== This is needed for the IOS platform, where the nxproxy model of forking does not work. Also NX handles most of the errors with an "exit" call which in IOS cannot be easily handled.
