wireless: Treat IPv6 diffserv the same as IPv4 for 802.11e

2012-01-04T19:30:43+00:00

Wireless will select a different hardware queue based on the
top 3 bits of the diffserv field, for ipv4. Extend that queue
selection mechanism to ipv6, and make the calls orthogonal.

cfg80211: Fix race in bss timeout

2011-12-13T20:30:28+00:00

It is quite possible to run into a race in bss timeout where
the drivers see the bss entry just before notifying cfg80211
of a roaming event but it got timed out by the time rdev->event_work
got scehduled from cfg80211_wq. This would result in the following
WARN-ON() along with the failure to notify the user space of
the roaming. The other situation which is happening with ath6kl
that runs into issue is when the driver reports roam to same AP
event where the AP bss entry already got expired. To fix this,
move cfg80211_get_bss() from __cfg80211_roamed() to cfg80211_roamed().

cfg80211: work around a sparse issue

2011-11-21T21:22:10+00:00

sparse reports:
net/wireless/util.c:499:30: error: cannot size expression
net/wireless/util.c:503:30: error: cannot size expression

This is evidently due to the EXPORT_SYMBOL() of the
bridge_tunnel_header and rfc1042 header variables.
Move them to the end of the file to work around the
sparse issue. The error itself from sparse can be
ignored safely, but since sparse stops parsing at
errors, other issues after this would go undetected.

cfg80211/mac80211: Revert "move information element parsing logic to cfg80211"

2011-11-21T21:20:49+00:00

No other driver ever ended up using this, and
the commit forgot to move the prototype so no
driver could have used it. Revert it, if any
driver shows up and needs it it can be moved
again, but until then it's more efficient to
have it in mac80211 where the only user is.

net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30+00:00

These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.

mac80211: data path modification for TDLS peers

2011-09-30T19:57:09+00:00

Mark the STA entries of enabled TDLS peers with a new "peer authorized"
flag.

During link setup, allow special TDLS setup frames through the AP, but
otherwise drop all packets destined to the peer. This is required by the
TDLS (802.11z) specification in order to prevent reordering of MSDUs
between the AP and direct paths.

When setup completes and the peer is authorized, send data directly,
bypassing the AP.

In the Rx path, allow data to be received directly from TDLS peers.

cfg80211: Validate cipher suite against supported ciphers

2011-09-27T18:29:54+00:00

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.
