Xbox One controllers that shipped with or were upgraded to the 2015
firmware discard the current rumble packets we send. This patch changes
the Xbox One rumble packet to a form that both the newer and older
firmware will accept.

It is based on changes made to support newer Xbox One controllers in
the SteamOS brewmaster-4.1 kernel branch.

After initially connecting a wired Xbox 360 controller or sending it
a command to change LEDs, a status/response packet is interpreted as
controller input. This causes the state of buttons represented in
byte 2 of the controller data packet to be incorrect until the next
valid input packet. Wireless Xbox 360 controllers are not affected.

Writing a new value to the LED device while holding the Start button
and running jstest is sufficient to reproduce this bug. An event will
come through with the Start button released.

Xboxdrv also won't attempt to read controller input from a packet
where byte 0 is non-zero. It also checks that byte 1 is 0x14, but
that value differs between wired and wireless controllers and this
code is shared by both. I think just checking byte 0 is enough to
eliminate unwanted packets.

The following are some examples of 3-byte status packets I saw:
01 03 02
02 03 00
03 03 03
08 03 00

Currently, when creating or updating a route, no check is performed
in both ipv4 and ipv6 code to the hoplimit value.

The caller can i.e. set hoplimit to 256, and when such route will
 be used, packets will be sent with hoplimit/ttl equal to 0.

This commit adds checks for the RTAX_HOPLIMIT value, in both ipv4
ipv6 route code, substituting any value greater than 255 with 255.

This is consistent with what is currently done for ADVMSS and MTU
in the ipv4 code.

The slab name ends up being visible in the directory structure under
/sys, and even if you don't have access rights to the file you can see
the filenames.

Just use a 64-bit counter instead of the pointer to the 'net' structure
to generate a unique name.

This code will go away in 4.7 when the conntrack code moves to a single
kmemcache, but this is the backportable simple solution to avoiding
leaking kernel pointers to user space.

  Given that it's a completely new feature and the patches don't touch
