 "Not much so far. We have the usual batch of bugs and two fixes to code
  merged this cycle:

   - Restore valgrind support for the ioctl verbs interface merged this
     window, and fix a missed error code on an error path from that
     conversion

   - A user reported crash on obsolete mthca hardware

   - pvrdma was using the wrong command opcode toward the hypervisor

   - NULL pointer crash regression when dumping rdma-cm over netlink

   - Be conservative about exposing the global rkey"

      drm/sun4i: backend: add missing of_node_puts · 4bb0e6d7
      Julia Lawall authored 
      The device node iterators perform an of_node_get on each
iteration, so a jump out of the loop requires an of_node_put.

Remote and port also have augmented reference counts, so drop them
on each iteration and at the end of the function, respectively.
Remote is only used for the address it contains, not for the
contents of that address, so the reference count can be dropped
immediately.

The semantic patch that fixes the first part of this problem is
as follows (http://coccinelle.lip6.fr):

// <smpl>
@@
expression root,e;
local idexpression child;
iterator name for_each_child_of_node;
@@

 for_each_available_child_of_node(root, child) {
   ... when != of_node_put(child)
       when != e = child
+  of_node_put(child);
?  break;
   ...
}
... when != child
// </smpl>

      seccomp: fix UAF in user-trap code · a811dc61
      Tycho Andersen authored 
      On the failure path, we do an fput() of the listener fd if the filter fails
to install (e.g. because of a TSYNC race that's lost, or if the thread is
killed, etc.). fput() doesn't actually release the fd, it just ads it to a
work queue. Then the thread proceeds to free the filter, even though the
listener struct file has a reference to it.

To fix this, on the failure path let's set the private data to null, so we
know in ->release() to ignore the filter.
