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.
