mac80211: connect with HT20 if HT40 is not permitted

2012-10-17T11:46:38Z

Some changes to fix issues with HT40 APs in Korea and follow-up changes to allow using HT40 even if the local regulatory database disallows it caused issues with iwlwifi (and could cause issues with other devices); iwlwifi firmware would assert if you tried to connect to an AP that has an invalid configuration (e.g. using HT40- on channel 140.) Fix this, while avoiding the "Korean AP" issue by disabling HT40 and advertising HT20 to the AP when connecting.

cfg80211/mac80211: avoid state mishmash on deauth

2012-10-15T15:21:34Z

Avoid situation when we are on associate state in mac80211 and on disassociate state in cfg80211. This can results on crash during modules unload (like showed on this thread: http://marc.info/?t=134373976300001&r=1&w=2) and possibly other problems.

mac80211: don't send delBA before disassoc

2012-09-21T14:14:13Z

When we disassociate, it's not really useful to send delBA action frames since we're going to send disassoc/deauth anyway, so change that. Signed-off-by: Johannes Berg

mac80211: change locking around ieee80211_recalc_smps

Make the function acquire the necessary mutex itself to simplify the callers. Signed-off-by: Johannes Berg

mac80211: handle power constraint/country IE better

2012-09-14T12:06:51Z

Currently, mac80211 uses the power constraint IE, and reduces the regulatory max TX power by it. This can cause issues if the AP is advertising a large power constraint value matching a high TX power in its country IE, for example in this case: ... Country: US Environment: Indoor/Outdoor ... Channels [157 - 157] @ 30 dBm ... Power constraint: 13 dB ... What happened here is that our local regulatory TX power is 15 dBm, and gets reduced by 13 dB so we end up with only 2 dBm effective TX power, which is way too low. Instead, handle the country IE/power constraint IE combined and restrict our TX power to the max of the regulatory power and the maximum power advertised by the AP, in this case 17 dBm (= 30 dBm - 13 dB). Also print a message when this happens to let the user know and help us debug issues with it. Reported-by: Carl A. Cook Tested-by: Carl A. Cook Signed-off-by: Johannes Berg

mac80211: move ieee80211_send_deauth_disassoc outside mlme code

2012-09-07T11:50:34Z

Move ieee80211_send_deauth_disassoc() to util.c to make it available for the rest of the mac80211 code. Signed-off-by: Antonio Quartulli [reword commit message] Signed-off-by: Johannes Berg

mac80211: check power constraint IE size when parsing

2012-09-06T15:11:00Z

The power constraint IE is always a single byte so check the size when parsing instead of later. Signed-off-by: Johannes Berg

mac80211: disconnect if channel switch fails

Disconnect from the AP if channel switching in the driver failed or if the new channel is unavailable. Signed-off-by: Johannes Berg

mac80211: clear bssid on auth/assoc failure

2012-09-04T15:14:19Z

ifmgd->bssid wasn't cleared properly in some auth/assoc failure cases, causing mac80211 and the low-level driver to go out of sync. Clear ifmgd->bssid on failure, and notify the driver. Cc: stable@kernel.org # 3.4+ Signed-off-by: Eliad Peller Signed-off-by: Johannes Berg
