+Subject: [PATCH] dix: allocate enough space for logical button maps
+
+Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for
+each logical button currently down. Since buttons can be arbitrarily mapped
+to anything up to 255 make sure we have enough bits for the maximum mapping.

+Subject: [PATCH] glx: Call XACE hooks on the GLX buffer
+
+The XSELINUX code will label resources at creation by checking the
+access mode. When the access mode is DixCreateAccess, it will call the
+function to label the new resource SELinuxLabelResource().
+
+However, GLX buffers do not go through the XACE hooks when created,
+hence leaving the resource actually unlabeled.
+
+When, later, the client tries to create another resource using that
+drawable (like a GC for example), the XSELINUX code would try to use
+the security ID of that object which has never been labeled, get a NULL
+pointer and crash when checking whether the requested permissions are
+granted for subject security ID.
+
+To avoid the issue, make sure to call the XACE hooks when creating the
+GLX buffers.
+
+Credit goes to Donn Seeley <donn@xmission.com> for providing the patch.

+Subject: [PATCH] ephyr,xwayland: Use the proper private key for cursor
+
+The cursor in DIX is actually split in two parts, the cursor itself and
+the cursor bits, each with their own devPrivates.
+
+The cursor itself includes the cursor bits, meaning that the cursor bits
+devPrivates in within structure of the cursor.
+
+Both Xephyr and Xwayland were using the private key for the cursor bits
+to store the data for the cursor, and when using XSELINUX which comes
+with its own special devPrivates, the data stored in that cursor bits'
+devPrivates would interfere with the XSELINUX devPrivates data and the
+SELINUX security ID would point to some other unrelated data, causing a
+crash in the XSELINUX code when trying to (re)use the security ID.
