branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.08.x
The last bump [1] forgot to rename the patch directory and remove
upstream patches.
We still need to fix the monotonic clock check which doesn't work
when cross-compiling.

-Subject: [PATCH] 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] 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: [PATCH] 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.
