This fixes bugs where the port is not receiving multicast or VLAN tagged
packets when in promiscuous mode. This can occur when a SW bridge is
created on top of the device.
This also fixes issues where the promiscuous behavior setting was not
being preserved across a reset caused by features being enabled or
disabled.
We are using defport instead of doing a true promiscuous mode because we do
not need to receive the SRIOV or VMDq VSI directed traffic which would suck
up bandwidth and is really not intended for the SW bridge.
In addition, with defport we get VLAN promiscuous behavior which is not
possible from the VSI level promiscuous setting.

Pull user namespace updates from Eric Biederman:
"This finishes up the changes to ensure proc and sysfs do not start
implementing executable files, as the there are application today that
are only secure because such files do not exist.
It akso fixes a long standing misfeature of /proc/<pid>/mountinfo that
did not show the proper source for files bind mounted from
/proc/<pid>/ns/*.
It also straightens out the handling of clone flags related to user
namespaces, fixing an unnecessary failure of unshare(CLONE_NEWUSER)
when files such as /proc/<pid>/environ are read while <pid> is calling
unshare. This winds up fixing a minor bug in unshare flag handling
that dates back to the first version of unshare in the kernel.
Finally, this fixes a minor regression caused by the introduction of
sysfs_create_mount_point, which broke someone's in house application,
by restoring the size of /sys/fs/cgroup to 0 bytes. Apparently that
application uses the directory size to determine if a tmpfs is mounted
on /sys/fs/cgroup.
The bind mount escape fixes are present in Al Viros for-next branch.
and I expect them to come from there. The bind mount escape is the
last of the user namespace related security bugs that I am aware of"

====================
flow_dissector: Paramterize dissection and other features
This patch set adds some new capabilities to flow_dissector:
- Add flags to flow dissector functions to control dissection
- Flag to stop dissection when L3 header is seen (don't
dissect L4)
- Flag to stop dissection when encapsulation is detected
- Flag to parse first fragment of fragmented packet. This
may provide L4 ports
- Added new reporting in key_control
- Packet is a fragment
- Packet is a first fragment
- Packet has encapsulation
Also:
- Make __skb_set_sw_hash a general function
- Create functions to get a flow hash based on flowi4 or flowi6
structures without an reference to an skbuff
- Ignore flow dissector return value from ___skb_get_hash. Just
use whatever key fields are found to make a hash
Tested:
Ran 200 netperf TCP_RR instances for IPv6 and IPv4. Did not see any
regression. Ran UDP_RR with 10000 byte request and response size
for IPv4 and IPv6, no regression observed however I did see better
performance with IPv6 flow labels due to use of flow labels for L4
hash.

In ___skb_get_hash ignore return value from skb_flow_dissect_flow_keys.
A failure in that function likely means that there was a parse error,
so we may as well use whatever fields were found before the error was
hit. This is also good because it means we won't keep trying to derive
the hash on subsequent calls to skb_get_hash for the same packet.

Add an input flag to flow dissector on rather dissection should be
stopped when a flow label is encountered. Presumably, the flow label
is derived from a sufficient hash of an inner transport packet so
further dissection is not needed (that is ports are not included in
the flow hash). Using the flow label instead of ports has the additional
benefit that packet fragments should hash to same value as non-fragments
for a flow (assuming that the same flow label is used).
We set this flag by default in for skb_get_hash.

Instead of returning immediately (on a parsing failure for instance) we

The problem is that mdiobus_unregister() deletes the bus device before
unregistering the phy devices on the bus. This wasn't a problem before
because the phys were not children of the bus:
/sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0:03
/sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0
But now that they are:
/sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0/xgene-mii-eth0:03
when mdiobus_unregister deletes the bus device, the phy subdirs are
removed from sysfs also. So when the phys are unregistered afterward,
we get the warning. This patch changes the order so that phys are
unregistered before the bus device is deleted.
