* [NET]: DIV_ROUND_UP cleanup (part two)Ilpo Järvinen2007-10-10
| | | | | | | | | | | Hopefully captured all single statement cases under net/. I'm not too sure if there is some policy about #includes that are "guaranteed" (ie., in the current tree) to be available through some other #included header, so I just added linux/kernel.h to each changed file that didn't #include it previously.

* [PATCH] softmac: Fix inability to associate with WEP networksLarry Finger2007-09-21
| | | | | | | | | | | Commit 4cf92a3c was submitted as a fix for bug #8686 at bugzilla.kernel.org (http://bugzilla.kernel.org/show_bug.cgi?id=8686). Unfortunately, the fix led to a new bug, reported by Yoshifuji Hideaki, that prevented association for WEP encrypted networks that use ifconfig to control the device. This patch effectively reverts the earlier commit and does a proper fix for bug #8686. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * [PATCH] ieee80211softmac: Fix setting of initial transmit ratesLarry Finger2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a bug in ieee80211softmac that always sets the user rate to 11Mbs, no matter the capabilities of the device. This bug was probably beneficial as long as the bcm43xx cards were rate limited; however, most are now capable of relatively high speeds. This patch fixes that bug and eliminates an assert that is no longer needed. Once the cards are capable of full OFDM speeds, the 24 Mbs rate will be changed to 54 Mbs.

* [PATCH] ieee80211softmac: Fix errors related to the work_struct changesUlrich Kunitz2006-12-19
| | | | | | | | | | | | | | | | | | | 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.

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.
