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).

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.

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].

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.

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

* 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.

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.
