lib80211: remove unused print_ssid()

2014-10-14T00:18:27+00:00

In kernel we have %*pE specifier to print an escaped buffer.  All users
now switched to that approach.

This fixes a bug as well.  The current implementation wrongly prints
octal numbers: only two first digits are used in case when 3 are
required and the rest of the string ends up cut off.

Additionally by default the \f, \v, \a, and \e are escaped to their
alphabetic representation.  It's safe to do since it is currently used
for messaging only.

====================
pull request: wireless-next 2014-09-22

Please pull this batch of updates intended for the 3.18 stream...

For the mac80211 bits, Johannes says:

"This time, I have some rate minstrel improvements, support for a very
small feature from CCX that Steinar reverse-engineered, dynamic ACK
timeout support, a number of changes for TDLS, early support for radio
resource measurement and many fixes. Also, I'm changing a number of
places to clear key memory when it's freed and Intel claims copyright
for code they developed."

For the bluetooth bits, Johan says:

"Here are some more patches intended for 3.18. Most of them are cleanups
or fixes for SMP. The only exception is a fix for BR/EDR L2CAP fixed
channels which should now work better together with the L2CAP
information request procedure."

For the iwlwifi bits, Emmanuel says:

"I fix here dvm which was broken by my last pull request. Arik
continues to work on TDLS and Luca solved a few issues in CT-Kill. Eyal
keeps digging into rate scaling code, more to come soon. Besides this,
nothing really special here."

Beyond that, there are the usual big batches of updates to ath9k, b43,
mwifiex, and wil6210 as well as a handful of other bits here and there.
Also, rtlwifi gets some btcoexist attention from Larry.

Please let me know if there are problems!
====================

Had to adjust the wil6210 code to comply with Joe Perches's recent
change in net-next to make the netdev_*() routines return void instead
of 'int'.

cfg80211: allow requesting SMPS mode on ap start

2014-09-11T11:37:02+00:00

Add feature bits to indicate device support for
static-smps and dynamic-smps modes.

Add a new NL80211_ATTR_SMPS_MODE attribue to allow
configuring the smps mode to be used by the ap
(e.g. configuring to ap to dynamic smps mode will
reduce power consumption while having minor effect
on throughput)

cfg80211/mac80211: add wmm info to assoc event

2014-09-11T10:24:39+00:00

Userspace might need to know what queues are configured
for uapsd (e.g. for setting proper default values in tspecs).

Add this bitmap to the association event (inside wmm
nested attribute)

Add additional parameter to cfg80211_rx_assoc_resp,
and update its callers.

cfg80211: add WMM traffic stream API

2014-09-11T10:21:18+00:00

Add nl80211 and driver API to validate, add and delete traffic
streams with appropriate settings.

The API calls for userspace doing the action frame handshake
with the peer, and then allows only to set up the parameters
in the driver. To avoid setting up a session only to tear it
down again, the validate API is provided, but the real usage
later can still fail so userspace must be prepared for that.

cfg80211: clear nl80211 messages carrying keys after processing

2014-09-11T10:07:39+00:00

Clear any nl80211 messages that might contain keys after
processing them to avoid leaving their data in memory
"forever" after they've been freed.

cfg80211: don't put kek/kck/replay counter on the stack

2014-09-11T10:07:34+00:00

There's no need to put the values on the stack, just pass a
pointer to the data in the nl80211 message. This reduces stack
usage and avoids potential issues with putting sensitive data
on the stack.

cfg80211: clear wext keys when freeing and removing them

2014-09-11T10:07:28+00:00

When freeing the keys stored for wireless extensions, clear the memory
to avoid having the key material stick around in memory "forever".
Similarly, when userspace overwrites a key, actually clear it instead
of just setting the key length to zero.
