mac80211: remove message on receiving unexpected unencrypted frames

2008-04-15T19:04:36Z

Some people are getting this message a lot, and we have traced it to broken access points that much too often send completely empty frames (all bytes zeroed, which they shouldn't do at all.) Since we cannot do anything about such frames in any case except the special case where we're debugging an AP, just remove the message. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: make alignment warning optional

2008-02-01T21:12:24Z

Driver authors should be aware of the alignment requirements, but not everybody cares about the warning. This patch makes it depend on a new Kconfig symbol MAC80211_DEBUG_PACKET_ALIGNMENT which can be enabled regardless of MAC80211_DEBUG and is recommended for driver authors (only). This also restricts the warning to data packets so other packets need not be realigned to not trigger the warning. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: fixing null qos data frames check for reordering buffer

2008-02-01T03:26:38Z

This patch fixes a wrong condition for null qos data frames, causing us to drop data frames needed for reordering as well. Signed-off-by: Ron Rindjunsky Signed-off-by: John W. Linville Signed-off-by: David S. Miller

mac80211: fix alignment warning

2008-02-01T03:26:34Z

When I introduced the alignment warning I forgot the A-MSDU case which has a different requirement because each frame contains 14-byte 802.3 headers in front of the IP payload. This patch moves the alignment warning to a place where we know whether we're dealing with an A-MSDU frame and adjusts it accordingly. Signed-off-by: Johannes Berg Signed-off-by: John W.

mac80211: fix rx flow sparse errors, make functions static

This patch adds static declarations to functions in the Rx flow in order to eliminate sparse errors Signed-off-by: Ron Rindjunsky Signed-off-by: Tomas Winkler Signed-off-by: John W. Linville

mac80211: fix RCU locking in __ieee80211_rx_handle_packet

2008-01-28T23:10:43Z

Commit c7a51bda ("mac80211: restructure __ieee80211_rx") extracted __ieee80211_rx_handle_packet out of __ieee80211_rx and hence changed the locking rules for __ieee80211_rx_handle_packet(), it is now invoked under RCU lock. There is, however, one instance left where it contains an rcu_read_unlock() in an error path, which is a bug. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: move interface type to vif structure

2008-01-28T23:09:37Z

Drivers that support mixed AP/STA operation may well need to know the type of a virtual interface when iterating over them. The easiest way to support that is to move the interface type variable into the vif structure. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: A-MPDU Rx adding BAR handling capability

mac80211: A-MPDU Rx handling aggregation reordering

2008-01-28T23:01:00Z

This patch handles the reordering of the Rx A-MPDU. This issue occurs when the sequence of the internal MPDUs is not in the right order. such a case can be encountered for example when some MPDUs from previous aggregations were recieved, while others failed, so current A-MPDU will contain a mix of re-transmited MPDUs and new ones.

mac80211: restructure __ieee80211_rx

2008-01-28T23:00:57Z

This patch makes a separation between Rx frame pre-handling which stays in __ieee80211_rx and Rx frame handlers, moving to __ieee80211_rx_handle_packet. Although this separation has no affect in regular mode of operation, this kind of mechanism will be used in A-MPDU frames reordering as it allows accumulation of frames during pre-handling, dispatching them to later handling when necessary.
