cxgb4: Add API to correctly calculate tuple fields

Adds constant definitions for TP_VLAN_PRI_MAP for the Compressed

Also, the CPL Parameters field for T5 is 40 bits so we need to prototype

cxgb4: Account for stid entries properly in case of IPv6
IPv6 uses 2 TIDs with CLIP enabled and 4 TIDs without CLIP.
Currently we are incrementing STIDs in use by 1 for both IPv4 and IPv6 which

Further, driver currently does not have interface to query if CLIP is programmed

by 4 for IPv6 assuming absence of CLIP. Such assumption keeps us on safe side and
we don't end up allocating more stids for IPv6 than actually supported.

net: inet_diag: zero out uninitialized idiag_{src,dst} fields
Jakub reported while working with nlmon netlink sniffer that parts of
the inet_diag_sockid are not initialized when r->idiag_family != AF_INET6.
That is, fields of r->id.idiag_src[1 ... 3], r->id.idiag_dst[1 ... 3].
In fact, it seems that we can leak 6 * sizeof(u32) byte of kernel [slab]
memory through this. At least, in udp_dump_one(), we allocate a skb in ...
rep = nlmsg_new(sizeof(struct inet_diag_msg) + ..., GFP_KERNEL);
... and then pass that to inet_sk_diag_fill() that puts the whole struct
inet_diag_msg into the skb, where we only fill out r->id.idiag_src[0],
r->id.idiag_dst[0] and leave the rest untouched:
r->id.idiag_src[0] = inet->inet_rcv_saddr;
r->id.idiag_dst[0] = inet->inet_daddr;
struct inet_diag_msg embeds struct inet_diag_sockid that is correctly /
fully filled out in IPv6 case, but for IPv4 not.
So just zero them out by using plain memset (for this little amount of
bytes it's probably not worth the extra check for idiag_family == AF_INET).
Similarly, fix also other places where we fill that out.

This patch is to fix a compiler warning of __bad_udelay due to a value
of >999 being passed as a parameter to udelay() in the function
e1000e_phy_has_link_generic(). This affects the gcc compiler when
it is given a flag of -O3 and the icc compiler.
This patch is also making the change from mdelay() to msleep() in the
same function, since it was determined though code inspection that this
function is never called in atomic context.

net: allow netdev_all_upper_get_next_dev_rcu with rtnl lock held
It is useful to be able to walk all upper devices when bringing
a device online where the RTNL lock is held. In this case it
is safe to walk the all_adj_list because the RTNL lock is used
to protect the write side as well.
This patch adds a check to see if the rtnl lock is held before
throwing a warning in netdev_all_upper_get_next_dev_rcu().
Also because we now have a call site for lockdep_rtnl_is_held()
outside COFIG_LOCK_PROVING an inline definition returning 1 is
needed. Similar to the rcu_read_lock_is_held().

neigh: Netlink notification for administrative NUD state change
The neighbour code sends up an RTM_NEWNEIGH netlink notification if
the NUD state of a neighbour cache entry is changed by a timer (e.g.
from REACHABLE to STALE), even if the lladdr of the entry has not
changed.
But an administrative change to the the NUD state of a neighbour cache
entry that does not change the lladdr (e.g. via "ip -4 neigh change
... nud ...") does not trigger a netlink notification. This means
that netlink listeners will not hear about administrative NUD state
changes such as from a resolved state to PERMANENT.
This patch changes the neighbor code to generate an RTM_NEWNEIGH
message when the NUD state of an entry is changed administratively.

the work in netvsc_change_mtu(), in the mean time, netdev_notify_peers() may be
called from worker and also trying to hold the rtnl_lock. This will lead the
flush won't succeed forever. Solve this by not canceling and flushing the work,
this is safe because the transmission done by NETDEV_NOTIFY_PEERS was

cpupower: Fix segfault due to incorrect getopt_long arugments
If a user calls 'cpupower set --perf-bias 15', the process will end with
a SIGSEGV in libc because cpupower-set passes a NULL optarg to the atoi
call. This is because the getopt_long structure currently has all of
the options as having an optional_argument when they really have a
required argument. We change the structure to use required_argument to
match the short options and it resolves the issue.

Bluetooth: Fix HCI User Channel permission check in hci_sock_sendmsg
The HCI User Channel is an admin operation which enforces CAP_NET_ADMIN
when binding the socket. Problem now is that it then requires also
CAP_NET_RAW when calling into hci_sock_sendmsg. This is not intended
and just an oversight since general HCI sockets (which do not require
special permission to bind) and HCI User Channel share the same code
path here.
Remove the extra CAP_NET_RAW check for HCI User Channel write operation
since the permission check has already been enforced when binding the
socket. This also makes it possible to open HCI User Channel from a
privileged process and then hand the file descriptor to an unprivilged
process.

Pull device mapper fixes from Mike Snitzer:
"A set of device-mapper fixes for 3.13.
A fix for possible memory corruption during DM table load, fix a
possible leak of snapshot space in case of a crash, fix a possible
deadlock due to a shared workqueue in the delay target, fix to
initialize read-only module parameters that are used to export metrics
for dm stats and dm bufio.
Quite a few stable fixes were identified for both the thin-
provisioning and caching targets as a result of increased regression
testing using the device-mapper-test-suite (dmts). The most notable
of these are the reference counting fixes for the space map btree that
is used by the dm-array interface -- without these the dm-cache
metadata will leak, resulting in dm-cache devices running out of
metadata blocks. Also, some important fixes related to the
thin-provisioning target's transition to read-only mode on error"
