2007-02-05[PATCH] softmac: avoid assert in ieee80211softmac_wx_get_rateJohn W. Linville1-0/+6
Unconfigured bcm43xx device can hit an assert() during wx_get_rate queries. This is because bcm43xx calls ieee80211softmac_start late (i.e. during open instead of probe). bcm43xx_net_open -> bcm43xx_init_board -> bcm43xx_select_wireless_core -> ieee80211softmac_start Fix is to check that device is running before completing ieee80211softmac_wx_get_rate.

2006-12-19[PATCH] ieee80211softmac: Fix errors related to the work_struct changesUlrich Kunitz1-2/+2
The signature of work functions changed recently from a context pointer to the work structure pointer. This caused a problem in the ieee80211softmac code, because the ieee80211softmac_assox_work function has been called directly with a parameter explicitly casted to (void*). This compiled correctly but resulted in a softlock, because mutex_lock was called with the wrong memory address. The patch fixes the problem. Another issue was a wrong call of the schedule_work function. Softmac works again and this fixes the problem I mentioned earlier in the zd1211rw rx tasklet patch. The patch is against Linus' tree (commit af1713e0).

2006-12-02[PATCH] ieee80211: Drop and count duplicate data frames to remove 'replay ↵Larry Finger1-0/+5
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.

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.

2006-11-28[PATCH] softmac: remove netif_tx_disable when scanningMichael Buesch1-2/+0
In the scan section of ieee80211softmac, network transmits are disabled. When SoftMAC re-enables transmits, it may override the wishes of a driver that may have very good reasons for disabling transmits. At least one failure in bcm43xx can be traced to this problem. In addition, several unexplained problems may arise from the unexpected enabling of transmits. Note that making this change introduces a new bug that would allow transmits for the current session to be transmitted on the wrong channel; however, the new bug is much less severe than the one being fixed, as the new one only leads to a few retransmits, whereas the old one can bring the interface down. A fix that will not introduce new bugs is being investigated; however, the current, more serious one should be fixed now.

2006-07-27[PATCH] softmac: ERP handling and driver-level notificationsDaniel Drake4-25/+96
This patch implements ERP handling in softmac so that the drivers can support protection and preambles properly. I added a new struct, ieee80211softmac_bss_info, which is used for BSS-dependent variables like these. A new hook has been added (bssinfo_change), which allows the drivers to be notified when anything in bssinfo changes. I modified the txrates_change API to match the bssinfo_change API. The existing one is a little messy and the usefulness of providing the old rates is questionable (and can be implemented at driver level if really necessary). No drivers are using this API (yet), so this should be safe. Signed-off-by: Daniel Drake <dsd@gentoo.org> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

To prevent this, I added a flag to stop multiple authentication attempts by the association layer.

2006-07-05[PATCH] 2.6.17 missing a call to ieee80211softmac_capabilities from ↵Larry Finger1-0/+3
ieee80211softmac_assoc_req In commit ba9b28d19a3251bb1dfe6a6f8cc89b96fb85f683, routine ieee80211softmac_capabilities was added to ieee80211softmac_io.c. As denoted by its name, it completes the capabilities IE that is needed in the associate and reassociate requests sent to the AP. For at least one AP, the Linksys WRT54G V5, the capabilities field must set the 'short preamble' bit or the AP refuses to associate. In the commit noted above, there is a call to the new routine from ieee80211softmac_reassoc_req, but not from ieee80211softmac_assoc_req. This patch fixes that oversight. As noted in the subject, v2.6.17 is affected. My bcm43xx card had been unable to associate since I was forced to buy a new AP. I finally was able to get a packet dump and traced the problem to the capabilities info. Although I had heard that a patch was "floating around", I had not seen it before 2.6.17 was released. As this bug does not affect security and I seem to have the only AP affected by it, there should be no problem in leaving it for 2.6.18.
