randr: Do not update ConnectionInfo if NULL

2021-06-08T06:20:05+00:00

Backport of this xorg-xserver commit: commit 941aeb3b92e644923bd112eef8023f033a140ee6 Author: Olivier Fourdan Date: Fri May 13 08:58:58 2016 +0200 randr: Do not update ConnectionInfo if NULL RRScreenSizeNotify() will update the connection information block, but if this occurs during initialization before ConnectionInfo is even initialized, this will lead to a crash. Simply check for ConnectionInfo prior to update it to avoid the crash.

randr: fix broken macros / memory corruption

2020-10-16T18:47:31+00:00

By casting the rrScrPriv to ScreenPtr we are using the offsets from the Screen structure for referencing data in the rrScrPriv structure causing data corruption. As both macros use the same casting this still works until the location where the data resides is overwritten. For 64bit the location was the "rotations" member in rrScrPriv which was not problematic because it is barely used. But on 32bit it was "numCrtcs" which is heavily used. On unwrap this was 0 and lead to a segfault. Fixes ArcticaProject/nx-libs#943

randr: always realloc crtcs and outputs

2017-12-07T06:20:55+00:00

Backported from X.org: commit 16381d186e7c791031392ed8afcfd33009854e9e Author: Giuseppe Bilotta giuseppe.bilotta@gmail.com Date: Thu Nov 9 10:21:20 2017 +0100 randr: always realloc crtcs and outputs When the last crtc (resp. output) is destroyed, the rrScrPriv crtcs (resp. outputs) fields do not get cleared, which can lead to a situation where the private's numCrtcs (resp. numOutputs) field is zero, but the associated memory is still allocated. Just checking if numCrtcs (resp. numOutputs) is zero is thus not a good criteria to determine whetehr to use a realloc or a malloc. Since crtcs (resp. outputs) are NULL-initialized anyway, relying on numCrtcs (resp. numOutputs) is actually unnecessary, because reallocation of a NULL ptr is equivalent to a malloc anyway. Therefore, just use realloc() unconditionally, and ensure that the fields are properly initialized.
