Amitkumar Karwar 5116f3cef2 mwifiex: update bss band information
In recent commit "mwifiex: use cfg80211 dynamic scan..."
(7c6fa2a843..) scan table handling in driver is removed to
make use of cfg80211 dynamic scan table. Now driver sends
beacon buffers found in scanning directly to stack and parse
the buffer for requested BSS only during association.

Beacon buffer doesn't contain bss band information. Driver
gets it from firmware in separate tlv (chan_band_tlv).
Currently since we don't inform stack about bss bandinfo,
there is an issue with 5GHz association.

Use "priv" field of struct cfg80211_bss to store bandinfo.
This fixes 5GHz association issue.

Amitkumar Karwar d06b7b9e1f mwifiex: fix 5GHz association issue
Sometimes association in 5GHz doesn't work. Dmesg log shows
"Can not find requested SSID xyz" error message. Currently
while preparing scan channel list for firmware Null entries
are created for disabled channels. The routine which retrieves
this list ignores channels after Null entry. Hence sometimes
driver doesn't scan the channel of requested AP and association
fails. The issue is fixed by avoiding those NULL entries.

Daniel Drake b4c3f34aff libertas: scan behaviour consistency improvements
When scanning for the broadcast SSID, there is no need to add the
SSID TLV (restoring the behaviour of the driver behaviour in the wext
days, confirmed in Marvell specifications).

If bssid is unspecified, the current scan code will usually fire off an
active scan probing for the specific requested SSID. However, if a scan
is ongoing (or has just finished), those scan results will be used
instead (even if that scan is totally different, e.g. a passive scan on
channel 4 for a different SSID). Fix this inconsistency by always
firing off a scan when associating without a bssid.

Jouni Malinen 38ba3c57af cfg80211: Validate cipher suite against supported ciphers
Instead of using a hardcoded list of cipher suites in nl80211.c, use a
shared function in util.c to verify that the driver advertises support
for the specified cipher. This provides more accurate validation of the
values and allows vendor-specific cipher suites to be added in drivers.

Jouni Malinen 6d30240e3d cfg80211: Remove strict validation of AKM suites
NL80211_ATTR_AKM_SUITES can be used to configure new AKMs, like FT or
the SHA-256 -based AKMs or FT from 802.11r/802.11w. In addition, vendor
specific AKMs could be used. The current validation code for the connect
command prevents cfg80211-based drivers from using these mechanisms even
if the driver would not actually use this AKM value (i.e., it uses
WPA/RSN IE from user space). mac80211-based drivers allow any AKM to be
used since this value is not used there.

Remove the unnecessary validation step in cfg80211 to allow drivers to
decide what AKMs are supported. In theory, we could handle this by
advertising supported AKMs, but that would not be very effective unless
we enforce all drivers (including mac80211) to advertise the set of
supported AKMs. This would require additional changes in many places
whenever a new AKM is introduced even though no actually functionality
changes may be required in most drivers.

Jouni Malinen 00b1edf169 ath6kl: fix TCP corruption
Commit 94e532d1a ("ath6kl: Fix system freeze under heavy data load")
aligns the skb data without checking if the skb is cloned. Because of
this ath6kl can corrupt the local TCP stack information that can result
in TCP retransmission failing and TCP connections stalling.

To avoid the corruption we need to copy the skb. Now the alignment
in ath6kl_htc_tx_buf_align() doesn't corrupt TCP packets anymore (and is
not even used for the cloned skb's that got copied since the alignment
of the data is handled at the copy time).

Johannes Berg 6c80c39d9a iwlagn: fix dangling scan request
If iwl_scan_initiate() fails for any reason,
priv->scan_request and priv->scan_vif are left
dangling. This can lead to a crash later when
iwl_bg_scan_completed() tries to run a pending
scan request.

In practice, this seems to be very rare due to
the STATUS_SCANNING check earlier. That check,
however, is wrong -- it should allow a scan to
be queued when a reset/roc scan is going on.
When a normal scan is already going on, a new
one can't be issued by mac80211, so that code
can be removed completely. I introduced this
bug when adding off-channel support in commit
266af4c745.

Kalle Valo 5694f96296 ath6kl: pass only unicast frames for aggregation
When pinging form ar6003 to the AP RTT was high even when power save was
disabled:

100 packets transmitted, 97 received, 3% packet loss, time 99125ms
rtt min/avg/max/mdev = 1.875/46.733/795.506/139.181 ms

After some investigation one reason for this was that received
multicast traffic confused the aggrecation logic and caused 400 ms
timeouts when receiving multicast frames from AP.

A simple way to fix is to pass only unicast frames for aggregation. This
improves RTT:

100 packets transmitted, 99 received, 1% packet loss, time 99144ms
rtt min/avg/max/mdev = 2.083/13.084/403.390/56.794 ms

Jouni Malinen 32c1087460 ath6kl: Export beacon interval and DTIM period through STA info
Now that we allow the first Beacon frame after each connection to
be processed at the host, we can figure out the DTIM period and
expose it with Beacon interval through STA info BSS parameters
to user space.

Jouni Malinen 551185ca0a ath6kl: Update BSS information after connection
Since we may end up using a dummy BSS entry when roaming, allow one Beacon
frame -based bssinfo from the current BSS to be processed prior to starting
to filter all bssinfo events. This allows cfg80211 BSS table to be filled
with proper data in the roaming case where the full Beacon data may not
have been present at the time of roamed event.

Jouni Malinen 82e14f56f7 ath6kl: Remove unnecessary bssinfo event header conversion
There is no point in unconditionally converting the bssinfo header
to the old version since only the new header is being used and the
driver can as well read the values from it when needed. Leaving out
the conversion saves some extra memory copying.

In addition, use the calculated "rssi" value snr - 95 dBm to get the
proper value in cfg80211 BSS table (i.e., something that more or less
matches with the value used in STA info).

Jouni Malinen 457fb0415a ath6kl: Remove the unused node table implementation
Now that the scan results are reported directly to the cfg80211 BSS
table there is no need for maintaining this internal node table
implementation for scan results. Remove the definitions and node
table functions.

Jouni Malinen 1aaa8c7469 ath6kl: Replace internal node table with cfg80211 BSS table
The internal node table in ath6kl was not really used for any useful
purpose. It was just used to collect scan results during a scan and then
provide them in a burst to cfg80211 at the completion of the scan. There
is no point in doing this since cfg80211 is perfectly capable of
maintaining the BSS table and the BSS inform messages are sent in
separate function calls anyway.

This provides more complete information in the cfg80211 BSS table since
this allows Beacon and Probe Response frames to be distinguished and IEs
from them reported separately.

Jouni Malinen 3b25ed186f ath6kl: Remove unnecessary node table update on disconnect event
Since ath6kl does not actually update cfg80211 BSS table when this
event occurs, there is not much need for removing the entries from
the internal table that is not really used or exposed.
