37beae65fa tools: selftests: psock_tpacket: get rid of macro wrappers
The TPACKET_V3 test code consists of a lot of unecessary macro
wrappers that rather obfuscate what members are accessed in what
way. So get rid of them and make the code more readable. Also
credit Chetan for providing tpacket_v3 example code. Furthermore,
get rid of private offset usage, as we do not need it here.

c590b5e2f0 ethtool: make .get_dump_data() harder to misuse by drivers
As the patch "bnx2x: remove zeroing of dump data buffer" showed,
it is too easy implement .get_dump_data incorrectly in a driver.

Let's make sure drivers cannot get confused by userspace requesting
a too big dump.

Also WARN if the driver sets dump->len to something weird and make
sure the length reported to userspace is the actual length of data
copied to userspace.

8cc2d927c2 bnx2x: fill in sane dump flag information
bnx2x did not set dump->version in its .get_dump_flag() method.
Let's set it to BNX2X_DUMP_VERSION. It's not a particularly nice
number (0x50acff01 currently), but at least it's something
deterministic.

dump->flag should report the value previously set using ethtool -W.

058eec4116 bnx2x: remove zeroing of dump data buffer
There is no need to initialize the dump data with zeros.
data is allocated with vzalloc, so it's already zero-filled.

More importantly, the memset is harmful, because dump->len (the length
requested by userspace) can be bigger than the allocated buffer (whose
size is determined by asking the driver's .get_dump_flag method).

e02010adee net: sctp: get rid of SCTP_DBG_TSNS entirely
After having reworked the debugging framework, Neil and Vlad agreed to
get rid of the leftover SCTP_DBG_TSNS code for a couple of reasons:

We can use systemtap scripts to investigate these things, we now have
pr_debug() helpers that make life easier, and if we really need anything
else besides those tools, we will be forced to come up with something
better than we have there. Therefore, get rid of this ifdef debugging
code entirely for now.

actually we can just hold idev->lock before taking pmc->mca_lock,
and avoid taking idev->lock again when iterating idev->addr_list,
since the upper callers of mld_newpack() already take
read_lock_bh(&idev->lock).

6c734fb859 gre: fix a regression in ioctl
When testing GRE tunnel, I got:

 # ip tunnel show
 get tunnel gre0 failed: Invalid argument
 get tunnel gre1 failed: Invalid argument

This is a regression introduced by commit c544193214
("GRE: Refactor GRE tunneling code.") because previously we
only check the parameters for SIOCADDTUNNEL and SIOCCHGTUNNEL,
after that commit, the check is moved for all commands.

So, just check for SIOCADDTUNNEL and SIOCCHGTUNNEL.

After this patch I got:

 # ip tunnel show

 gre1: gre/ip  remote 192.168.122.101  local 192.168.122.45  ttl inherit

bb33381d0c net: sctp: rework debugging framework to use pr_debug and friends
We should get rid of all own SCTP debug printk macros and use the ones
that the kernel offers anyway instead. This makes the code more readable
and conform to the kernel code, and offers all the features of dynamic
debbuging that pr_debug() et al has, such as only turning on/off portions
of debug messages at runtime through debugfs. The runtime cost of having
CONFIG_DYNAMIC_DEBUG enabled, but none of the debug statements printing,
is negligible [1]. If kernel debugging is completly turned off, then these
statements will also compile into "empty" functions.

While we're at it, we also need to change the Kconfig option as it /now/
only refers to the ifdef'ed code portions in outqueue.c that enable further
debugging/tracing of SCTP transaction fields. Also, since SCTP_ASSERT code
was enabled with this Kconfig option and has now been removed, we
transform those code parts into WARNs resp. where appropriate BUG_ONs so
that those bugs can be more easily detected as probably not many people
have SCTP debugging permanently turned on.

To turn on all SCTP debugging, the following steps are needed:

 # mount -t debugfs none /sys/kernel/debug
 # echo -n 'module sctp +p' > /sys/kernel/debug/dynamic_debug/control

This can be done more fine-grained on a per file, per line basis and others
as described in [2].

1067964305 lib: vsprintf: add IPv4/v6 generic %p[Ii]S[pfs] format specifier
In order to avoid making code that deals with printing both, IPv4 and
IPv6 addresses, unnecessary complicated as for example ...

  if (sa.sa_family == AF_INET6)
    printk("... %pI6 ...", ..sin6_addr);
  else
    printk("... %pI4 ...", ..sin_addr.s_addr);

... it would be better to introduce a format specifier that can deal
with those kind of situations internally; just as we have a "struct
sockaddr" for generic mapping into "struct sockaddr_in" or "struct
sockaddr_in6" as e.g. done in "union sctp_addr". Then, we could
reduce the above statement into something like:

  printk("... %pIS ..", &sockaddr);

In case our pointer is NULL, pointer() then deals with that already at
an earlier point in time internally. While we're at it, support for both
%piS/%pIS, where 'S' stands for sockaddr, comes (almost) for free.

Additionally to that, postfix specifiers 'p', 'f' and 's' are supported
as suggested and initially implemented in 2009 by Joe Perches [1].
Handling of those additional specifiers orientate on the initial RFC that
was proposed. Also we support IPv6 compressed format specified by 'c' and
various other IPv4 extensions as stated in the documentation part.

Likely, there are many other areas than just SCTP in the kernel to make
use of this extension as well.

c9ab4d85de neighbour: fix a race in neigh_destroy()
There is a race in neighbour code, because neigh_destroy() uses
skb_queue_purge(&neigh->arp_queue) without holding neighbour lock,
while other parts of the code assume neighbour rwlock is what
protects arp_queue

Convert all skb_queue_purge() calls to the __skb_queue_purge() variant

Use __skb_queue_head_init() instead of skb_queue_head_init()
to make clear we do not use arp_queue.lock

And hold neigh->lock in neigh_destroy() to close the race.

52bd4c0c15 ipv6: fix ecmp lookup when oif is specified
There is no reason to skip ECMP lookup when oif is specified, but this implies
to check oif given by user when selecting another route.
When the new route does not match oif requirement, we simply keep the initial
one.

5c29fb12e8 ipv6: only apply anti-spoofing checks to not-pointopoint tunnels
Because of commit 218774dc34 ("ipv6: add
anti-spoofing checks for 6to4 and 6rd") the sit driver dropped packets
for 2002::/16 destinations and sources even when configured to work as a
tunnel with fixed endpoint. We may only apply the 6rd/6to4 anti-spoofing
checks if the device is not in pointopoint mode.

This was an oversight from me in the above commit, sorry.  Thanks to
Roman Mamedov for reporting this!

John W. Linville says:

====================
Yet one more pull request for wireless updates intended for 3.11...

For the mac80211 bits, Johannes says:

"Here we have a few memory leak fixes related to BSS struct handling
mostly from Ben, including a fix for a more theoretical problem
(associating while a BSS struct times out) from myself, a compilation
warning fix from Arend, mesh fixes from Thomas, tracking the beacon
bitrate (Alex), a bandwidth change event fix (Ilan) and some initial
work for 5/10 MHz channels from Simon."

Regarding the iwlwifi bits, Johannes says:

"Emmanuel removed some unneeded/unsupported module parameters and adds a
Bluetooth 1x1 lookup-table for some upcoming products. From Alex I have
an older patch to add low-power receive support, this depended on a
mac80211 commit that only just came in with the merge from wireless-next
I did. Ilan made beacon timings better, and Eytan added some debug
statements for thermal throttling. I have a few cleanups, a fix for a
long-standing but rare warning, and, arguably the most important patch
here, the firmware API version bump for the 7260/3160 devices."

Also included is a Bluetooth pull -- Gustavo says:

"Here goes a set of patches to 3.11. The biggest work here is from Andre Guedes
on the move of the Discovery to use the new request framework. Other than that
Johan provided a bunch of fixes to the L2CAP code. The rest are just small
fixes and clean ups."

On top of all that, there are a variety of updates and fixes to
brcmfmac, rt2x00, wil6210, ath9k, ath10k, and a few others here and
there.  This also includes a pull of the wireless tree, in order to
prevent some merge conflicts.

b01978cacf net/mlx4_core: Dynamic VST to VST vlan/qos changes
Within VST mode, enable modifying the vlan and/or qos
for a VF without requiring unbind/rebind.

This requires firmware which supports the UPDATE_QP command.
(If the command is not available, we fall back to requiring
unbind/bind to activate these changes).

To avoid race conditions with modify-qp on QPs that are affected
by update-qp, this operation is performed on the comm_wq.

If the update operation succeeds for all the necessary QPs, a
vlan_unregister is performed for the abandoned vlan id.

they are:

* Enforce policy to several nfnetlink subsystem, from Daniel

* Use xt_socket to match the third packet (to perform simplistic
  socket-based stateful filtering), from Eric Dumazet.

* Avoid large timeout for picked up from the middle TCP flows,
  from Florian Westphal.

* Exclude IPVS from struct net if IPVS is disabled and removal
  of unnecessary included header file, from JunweiZhang.

* Release SCTP connection immediately under load, to mimic current
  TCP behaviour, from Julian Anastasov.

* Replace and enhance SCTP state machine, from Julian Anastasov.

* Add tweak to reduce sync traffic in the presence of persistence,
  also from Julian Anastasov.

* Add tweak for the IPVS SH scheduler not to reject connections
  directed to a server, choose a new one instead, from Alexander
  Frolkin.

* Add support for sloppy TCP and SCTP modes, that creates state
  information on any packet, not only initial handshake packets,
  from Alexander Frolkin.

496e4ae7dc netfilter: nf_queue: add NFQA_SKB_CSUM_NOTVERIFIED info flag
The common case is that TCP/IP checksums have already been
verified, e.g. by hardware (rx checksum offload), or conntrack.

Userspace can use this flag to determine when the checksum
has not been validated yet.

If the flag is set, this doesn't necessarily mean that the packet has
an invalid checksum, e.g. if NIC doesn't support rx checksum.

Userspace that sucessfully enabled NFQA_CFG_F_GSO queue feature flag can
infer that IP/TCP checksum has already been validated if either the
SKB_INFO attribute is not present or the NFQA_SKB_CSUM_NOTVERIFIED
flag is unset.

3b233fe043 nlmon: fix comparison in nlmon_is_valid_mtu
This patch fixes the following warning introduced in e4fc408e0e
("packet: nlmon: virtual netlink monitoring device for packet
sockets") reported by Dan Carpenter:

warning: "drivers/net/nlmon.c:31 nlmon_is_valid_mtu()
	 warn: always true condition '(new_mtu <= ((~0 >> 1))) =>
				      (s32min-s32max <= s32max)'"

Thus, we should simply remove the test against INT_MAX. Next to that
we also need to explicitly cast the sizeof() case as the comparison
is type promoted to unsigned long so negative values are then
valid instead of invalid. While at it, this also adds a comment about
Netlink and MTUs.
