Merge tag 'md/3.15-fixes' of git://neil.brown.name/md

Pull two md bugfixes from Neil Brown:
 "Two md bugfixes for possible corruption when restarting reshape

  If a raid5/6 reshape is restarted (After stopping and re-assembling
  the array) and the array is marked read-only (or read-auto), then the
  reshape will appear to complete immediately, without actually moving
  anything around.  This can result in corruption.

  There are two patches which do much the same thing in different
  places.  They are separate because one is an older bug and so can be
  applied to more -stable kernels"

* tag 'md/3.15-fixes' of git://neil.brown.name/md:
  md: always set MD_RECOVERY_INTR when interrupting a reshape thread.
  md: always set MD_RECOVERY_INTR when aborting a reshape or other "resync".
atm: fore200e.c: Cleaning up uninitialized variables

There is a risk that the variable will be used without being initialized.

This was largely found by using a static code analysis program called cppcheck.

net: filter: fix possible memory leak in __sk_prepare_filter()

__sk_prepare_filter() was reworked in commit bd4cf0ed3 (net: filter:
rework/optimize internal BPF interpreter's instruction set) so that it should
have uncharged memory once things went wrong. However that work isn't complete.
Error is handled only in __sk_migrate_filter() while memory can still leak in
the error path right after sk_chk_filter().

bridge: Add bridge ifindex to bridge fdb notify msgs

(This patch was previously posted as RFC at
http://patchwork.ozlabs.org/patch/352677/)

This patch adds NDA_MASTER attribute to neighbour attributes enum for
bridge/master ifindex. And adds NDA_MASTER to bridge fdb notify msgs.

Today bridge fdb notifications dont contain bridge information.
Userspace can derive it from the port information in the fdb
notification. However this is tricky in some scenarious.

Example, bridge port delete notification comes before bridge fdb
delete notifications. And we have seen problems in userspace
when using libnl where, the bridge fdb delete notification handling code
does not understand which bridge this fdb entry is part of because
the bridge and port association has already been deleted.
And these notifications (port membership and fdb) are generated on
separate rtnl groups.

Fixing the order of notifications could possibly solve the problem
for some cases (I can submit a separate patch for that).

This patch chooses to add NDA_MASTER to bridge fdb notify msgs
because it not only solves the problem described above, but also helps
userspace avoid another lookup into link msgs to derive the master index.
