2006-12-02[PATCH] ieee80211: Drop and count duplicate data frames to remove 'replay ↵Larry Finger
detected' log messages In the SoftMAC version of the IEEE 802.11 stack, not all duplicate messages are detected. For the most part, there is no difficulty; however for TKIP and CCMP encryption, the duplicates result in a "replay detected" log message where the received and previous values of the TSC are identical. This change adds a new variable to the ieee80211_device structure that holds the 'seq_ctl' value for the previous frame. When a new frame repeats the value, the frame is dropped and the appropriate counter is incremented. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

2006-12-02[PATCH] ieee80211: Move IV/ICV stripping into ieee80211_rxDaniel Drake
This patch adds a host_strip_iv_icv flag to ieee80211 which indicates that ieee80211_rx should strip the IV/ICV/other security features from the payload. This saves on some memmove() calls in the driver and seems like something that belongs in the stack as it can be used by bcm43xx, ipw2200, and zd1211rw I will submit the ipw2200 patch separately as it needs testing. This patch also adds some sensible variable reuse (idx vs keyidx) in ieee80211_rx Signed-off-by: Daniel Drake <dsd@gentoo.org> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2006-10-31[PATCH] ieee80211: don't flood log with errorsJiri Benc
The "ieee80211: Workaround malformed 802.11 frames from AP" patch (see http://kernel.org/git/?p=linux/kernel/git/linville/wireless-2.6.git;a=commit;h=f09fc44d8c25f22c4d985bb93857338ed02feac6 ) fixes the problem with some buggy APs but also converts debug message into an error one. This floods the log with errors when you are near such AP (you get a message for every beacon). This patch reverts the error message back to the debug one.

2006-08-29[PATCH] ieee80211: Workaround malformed 802.11 frames from APZhu Yi
Stop processing further but return success when we receive a malformed packet from the AP. We need this patch to workaround some AP bugs. For example, the beacon frames from the Orinoco AP1000 contains an IE (value = 128) with length equals to 8 but the actual frame length is only 7.

ieee80211_rx_any is new to 2.6.18-rc1, even though it appears this function was never completed: http://lists.sipsolutions.net/pipermail/softmac-dev/2006-February/000103.html This patch changes ieee80211_rx_any to always claim the skb, which avoids further driver complexity and the possibility of leaking management frames.

2006-07-27[PATCH] ieee80211: small ERP handling additionsDaniel Drake
This adds a flag to the ieee80211_network structure which indicates whether the stored erp_value is valid (a check against 0 is not enough, since an ERP of 0 is valid and very meaningful). I also added the ERP IE bit-definitions to ieee80211.h. This is needed by some upcoming softmac patches.

2006-03-17[PATCH] ieee80211: Don't update network statistics from off-channel packets.James Ketrenos
This patch fixes a problem in the ieee80211 probe response and beacon reception code that would use the packet statistics for a network even if they were received on a channel other than that which the network exists on. This causes a problem in overlapping channels where, for example, a strong AP on channel 2 could have its beacons received on channels 1 and 3, but at much lower signal levels. If scanning was done sequentially, this means the beacon received on channel 3 would update the AP's signal level as being much lower than it really is, which subsequently could cause that AP to be passed over and an alternate AP selected.
