For direct contexts, most context attributes don't require any
particular awareness on the part of the server. Examples include
GLX_ARB_create_context_no_error and GLX_ARB_context_flush_control, where
all of the behavior change lives in the renderer; since that's on the
client side for a direct context, there's no reason for the X server to
validate the attribute.
The context attributes will still be validated on the client side, and
we still validate attributes for indirect contexts since the server
implementation might need to handle them. For example, the indirect
code might internally use ARB_context_flush_control for all contexts, in
which case it would need to manually emit glFlush when the client
switches between two indirect contexts that didn't request the no-flush
attribute.

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.

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.

This currently does a meson build using a docker image I've prepared.
The Dockerfile source is at:
https://github.com/anholt/xserver-travis
Docker proved to be necessary to cut the build time per Travis push.
If some day we end up using meson in more of the X stack, we may be
able to move more dependencies out of the docker image and into the CI
build (putting the I in CI). Until then, we'll have to do docker
image rebuilds when dependencies are added/updated.
To enable Travis CI on your github repository, see the first two steps
of the docs at:
https://docs.travis-ci.com/user/getting-started/
Once you do that, pushing branches to your github repo will trigger
builds, which will send you email if they fail. Current build status
can be veiewed your account on travis-ci.org:
