+Subject: [PATCH] glamor: make current in prepare paths
+
+Lots of the accel paths only make current once they start
+doing someting, so a lot of them call the bail paths without
+make current, which means on PRIME systems for example
+we end up in the wrong context.
+
+Add a prepare pixmap in the prepare fallback path.

+Subject: [PATCH] os: make sure the clientsWritable fd_set is initialized
+ before use
+
+In WaitForSomething(), the fd_set clientsWritable may be used unitialized when
+the boolean AnyClientsWriteBlocked is set in the WakeupHandler(). This leads to
+a crash in FlushAllOutput() after x11proto's commit
+2c94cdb453bc641246cc8b9a876da9799bee1ce7.
+
+The problem did not manifest before because both the XFD_SIZE and the maximum
+number of clients were set to 256. As the connectionTranslation table was
+initalized for the 256 clients to 0, the test on the index not being 0 was
+aborting before dereferencing the client #0.
+
+As of commit 2c94cdb453bc641246cc8b9a876da9799bee1ce7 in x11proto, the XFD_SIZE
+got bumped to 512. This lead the OutputPending fd_set to have any fd above 256
+to be uninitialized which in turns lead to reading an index after the end of
+the ConnectionTranslation table. This index would then be used to find the
+client corresponding to the fd marked as pending writes and would also result
+to an out-of-bound access which would usually be the fatal one.
+
+Fix this by zeroing the clientsWritable fd_set at the beginning of
+WaitForSomething(). In this case, the bottom part of the loop, which would
+indirectly call FlushAllOutput, will not do any work but the next call to
+select will result in the execution of the right codepath. This is exactly what
+we want because we need to know the writable clients before handling them. In
+the end, it also makes sure that the fds above MaxClient are initialized,
+preventing the crash in FlushAllOutput().
+
+Thanks to everyone involved in tracking this one down!
