2006-05-05[PATCH] softmac: make non-operational after being stoppedDaniel Drake4-2/+38
zd1211 with softmac and wpa_supplicant revealed an issue with softmac and the use of workqueues. Some of the work functions actually reschedule themselves, so this meant that there could still be pending work after flush_scheduled_work() had been called during ieee80211softmac_stop(). This patch introduces a "running" flag which is used to ensure that rescheduling does not happen in this situation. I also used this flag to ensure that softmac's hooks into ieee80211 are non-operational once the stop operation has been started. This simply makes softmac a little more robust, because I could crash it easily by receiving frames in the short timeframe after shutting down softmac and before turning off the ZD1211 radio. (ZD1211 is now fixed as well!) Signed-off-by: Daniel Drake <dsd@gentoo.org> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2006-05-05[PATCH] softmac: don't reassociate if user asked for deauthenticationDaniel Drake1-2/+3
When wpa_supplicant exits, it uses SIOCSIWMLME to request deauthentication. softmac then tries to reassociate without any user intervention, which isn't the desired behaviour of this signal. This change makes softmac only attempt reassociation if the remote network itself deauthenticated us.

2006-04-24[PATCH] softmac: fix SIOCSIWAPJohannes Berg3-14/+35
There are some bugs in the current implementation of the SIOCSIWAP wext, for example that when you do it twice and it fails, it may still try another access point for some reason. This patch fixes this by introducing a new flag that tells the association code that the bssid that is in use was fixed by the user and shouldn't be deviated from.

2006-04-19[PATCH] softmac: report when scanning has finishedJohannes Berg1-0/+6
Make softmac report a scan event when scanning has finished, that way userspace can wait for the event to happen instead of polling for the results. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2006-04-19[PATCH] softmac: fix event sendingJohannes Berg2-5/+31
Softmac is sending custom events to userspace already, but it should _really_ be sending the right WEXT events instead. This patch fixes that.

2006-04-19[PATCH] softmac: handle iw_mode properlyjohannes@sipsolutions.net1-3/+15
Below patch allows using iw_mode auto with softmac. bcm43xx forces managed so this bug wasn't noticed earlier, but this was one of the problems why zd1211 didn't work earlier. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2006-04-19[PATCH] softmac: dont send out packets while scanningjohannes@sipsolutions.net1-0/+2
Seems we forgot to stop the queue while scanning. Better do that so we don't transmit packets all the time during background scanning. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2006-04-19[PATCH] softmac: return -EAGAIN from getscan while scanningjohannes@sipsolutions.net1-0/+10
Below patch was developed after discussion with Daniel Drake who mentioned to me that wireless tools expect an EAGAIN return from getscan so that they can wait for the scan to finish before printing out the results.

2006-04-19[PATCH] softmac: fix spinlock recursion on reassocMichael Buesch1-1/+2
This fixes a spinlock recursion on receiving a reassoc request. On reassoc, the softmac calls back into the driver. This results in a driver lock recursion. This schedules the assoc workqueue, instead of calling it directly. Probably, we should defer the _whole_ management frame processing to a tasklet or workqueue, because it does several callbacks into the driver. That is dangerous. This fix should go into linus's tree, before 2.6.17 is released, because it is remote exploitable (DoS by crash). Signed-off-by: John W. Linville <linville@tuxdriver.com>

2006-03-27[PATCH] softmac: reduce default rate to 11Mbps.David Woodhouse2-10/+19
We don't make much of an attempt to fall back to lower rates, and 54M just isn't reliable enough for many people. In fact, it's not clear we even set it to 11M if we're trying to associate with an 802.11b AP. This patch makes us default to 11M, which ought to work for most people. When we actually handle dynamic rate adjustment, we can reconsider the defaults -- but even then, probably it makes as much sense to start at 11M and adjust it upwards as it does to start at 54M and reduce it.

2006-03-27[PATCH] softmac: reduce scan dwell timeDavid Woodhouse1-1/+1
It currently takes something like 8 seconds to do a scan, because we spend half a second on each channel. Reduce that time to 20ms per channel. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2006-03-27[PATCH] Minor (janitorial) change to ieee80211Larry Finger1-2/+2
The attached patch removes a potential problem from ieee80211_wx.c, by changing the name of routine ipw2100_translate_scan to ieee80211_translate_scan. The problem is minor as the routine is declared static; however, if it were made global, it would pollute the namespace. Signed-Off-By: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

2006-03-23[PATCH] Restore channel setting after scan.David Woodhouse1-0/+7
After a scan, we weren't switching back to the original channel if we were associated with an AP. So NetworkManager's periodic scans would disrupt connectivity until the ESSID was manually set again.

2006-03-22[PATCH] ieee80211_rx_any: filter out packets, call ieee80211_rx or ieee80211_rx_mgtDenis Vlasenko1-0/+74
Version 2 of the patch. Added checks for version 0 and proper from/to DS bits. Even in promisc mode we won't receive packets from another BSSes. bcm43xx_rx() contains code to filter out packets from foreign BSSes and decide whether to call ieee80211_rx or ieee80211_rx_mgt. This is not bcm specific. Patch adapts that code and adds it to 80211 as ieee80211_rx_any() function. Signed-off-by: Denis Vlasenko <vda@ilport.com.ua> Signed-off-by: John W.

2006-03-17[PATCH] ieee80211: Don't update network statistics from off-channel packets.James Ketrenos1-1/+13
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.

Fix QoS is not active even the network and the card is QOS enabled. The problem is we pass the wrong ieee80211_network address to ipw_handle_beacon/ipw_handle_probe_response, thus the ieee80211_network->qos_data.active will not be set, causing the driver not sending QoS frames at all.

2006-02-27[PATCH] ieee80211_geo.c: remove frivolous BUG_ON'sPete Zaitcev1-3/+6
I have come to consider BUG_ON generally harmful. The idea of an assert is to prevent a program to execute past a point where its state is known erroneous, thus preventing it from dealing more damage to the data (or hiding the traces of malfunction). The problem is, in kernel this harm has to be balanced against the harm of forced reboot. The last straw was our softmac tree, where "iwlist eth1 scan" causes a lockup. It is absolutely frivolus and provides no advantages a normal assert has to provide. In fact, doing this impedes debugging. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: John W.

This patch creates two functions ieee80211_wx_set_auth and ieee80211_wx_get_auth that can be used by drivers for the wireless extension handlers instead of writing their own, if the implementation should be software only. These patches enable using bcm43xx devices with WPA and this seems (as far as I can tell) to be the only difference between the stock ieee80211 and softmac's ieee80211 left.
