-Subject: dix: Disallow GenericEvent in SendEvent request.
-
-The SendEvent request holds xEvent which is exactly 32 bytes long, no more,
-no less. Both ProcSendEvent and SProcSendEvent verify that the received data
-exactly match the request size. However nothing stops the client from passing
-in event with xEvent::type = GenericEvent and any value of
-xGenericEvent::length.
-
-In the case of ProcSendEvent, the event will be eventually passed to
-WriteEventsToClient which will see that it is Generic event and copy the
-arbitrary length from the receive buffer (and possibly past it) and send it to
-the other client. This allows clients to copy unitialized heap memory out of X
-server or to crash it.
-
-In case of SProcSendEvent, it will attempt to swap the incoming event by
-calling a swapping function from the EventSwapVector array. The swapped event
-is written to target buffer, which in this case is local xEvent variable. The
-xEvent variable is 32 bytes long, but the swapping functions for GenericEvents
-expect that the target buffer has size matching the size of the source
-GenericEvent. This allows clients to cause stack buffer overflows.

-Subject: Xi: Do not try to swap GenericEvent.
-
-The SProcXSendExtensionEvent must not attempt to swap GenericEvent because
-it is assuming that the event has fixed size and gives the swapping function
-xEvent-sized buffer.
-
-A GenericEvent would be later rejected by ProcXSendExtensionEvent anyway.

-Subject: Xi: Zero target buffer in SProcXSendExtensionEvent.
-
-Make sure that the xEvent eventT is initialized with zeros, the same way as
-in SProcSendEvent.
-
-Some event swapping functions do not overwrite all 32 bytes of xEvent
-structure, for example XSecurityAuthorizationRevoked. Two cooperating
-clients, one swapped and the other not, can send
-XSecurityAuthorizationRevoked event to each other to retrieve old stack data
-from X server. This can be potentialy misused to go around ASLR or
-stack-protector.

-Subject: [PATCH] modesetting: Set correct DRM event context version
-
-DRM_EVENT_CONTEXT_VERSION is the latest context version supported by
-whatever version of libdrm is present. modesetting was blindly asserting
-it supported whatever version that may be, even if it actually didn't.
-
-With libdrm 2.4.78, setting a higher context version than 2 will attempt
-to call the page_flip_handler2 vfunc if it was non-NULL, which being a
-random chunk of stack memory, it might well have been.
-
-Set the version as 2, which should be bumped only with the appropriate
-version checks.
