File 0001-Xinput-Catch-missing-configlayout-when-deleting-dev.patch of Package xorg-x11-server
>From 829037395f8b93e69a30852a95e378f78c3ccd6b Mon Sep 17 00:00:00 2001 From: Luc Verhaegen <libv@skynet.be> Date: Wed, 12 Nov 2008 17:09:33 +0100 Subject: [PATCH] Xinput: Catch missing configlayout when deleting device. In DeleteInputDeviceRequest (xf86Xinput.c), we access idev members even if idev is null. This takes down the xserver hard in some cases (kernel SIGABRT), and segfaults on other cases. ================================================================================ --- xorg-server-1.7.99/hw/xfree86/common/xf86Xinput.c +++ xorg-server-1.7.99/hw/xfree86/common/xf86Xinput.c @@ -870,17 +870,20 @@ else xf86DeleteInput(pInfo, 0); - /* devices added through HAL aren't in the config layout */ - it = xf86ConfigLayout.inputs; - while(*it && *it != idev) - it++; - - if (!(*it)) /* end of list, not in the layout */ + if (idev) { - free(idev->driver); - free(idev->identifier); - xf86optionListFree(idev->commonOptions); - free(idev); + /* devices added through HAL aren't in the config layout */ + it = xf86ConfigLayout.inputs; + while(*it && *it != idev) + it++; + + if (!(*it)) /* end of list, not in the layout */ + { + free(idev->driver); + free(idev->identifier); + xf86optionListFree(idev->commonOptions); + free(idev); + } } } OsReleaseSignals();
