mac80211: fix ibss scanning

2013-01-17T16:46:36Z

commit 34bcf71502413f8903ade93746f2d0f04b937a78 upstream. Do not scan on no-IBSS and disabled channels in IBSS mode. Doing this can trigger Microcode errors on iwlwifi and iwlegacy drivers. Also rename ieee80211_request_internal_scan() function since it is only used in IBSS mode and simplify calling it from ieee80211_sta_find_ibss(). This patch should address: https://bugzilla.redhat.com/show_bug.cgi?id=883414 https://bugzilla.kernel.org/show_bug.cgi?id=49411 Reported-by: Jesse Kahtava Reported-by: Mikko Rapeli Signed-off-by: Stanislaw Gruszka Signed-off-by: Johannes Berg Signed-off-by: Greg Kroah-Hartman

mac80211: deinitialize ibss-internals after emptiness check

2012-11-13T20:35:07Z

The check whether the IBSS is active and can be removed should be performed before deinitializing the fields used for the check/search. Otherwise, the configured BSS will not be found and removed properly. To make it more clear for the future, rename sdata->u.ibss to the local pointer ifibss which is used within the checks. This behaviour was introduced by f3209bea110cade12e2b133da8b8499689cb0e2e ("mac80211: fix IBSS teardown race") Cc: stable@vger.kernel.org Cc: Ignacy Gawedzki Signed-off-by: Simon Wunderlich Signed-off-by: Johannes Berg

mac80211: fix SSID copy on IBSS JOIN

2012-10-26T20:52:18Z

The 'ssid' field of the cfg80211_ibss_params is a u8 pointer and its length is likely to be less than IEEE80211_MAX_SSID_LEN most of the time. This patch fixes the ssid copy in ieee80211_ibss_join() by using the SSID length to prevent it from reading beyond the string.

mac80211: fix IBSS auth TX debug message

2012-09-20T08:31:34Z

In the IBSS auth TX debug message the BSSID and DA address are reversed, fix that. Signed-off-by: Sylvain Roger Rieunier [reword commit message and make it fit 72 cols] Signed-off-by: Johannes Berg

mac80211: reply to AUTH with DEAUTH if sta allocation fails in IBSS

2012-09-07T11:50:47Z

Whenever a host gets an AUTH frame it first allocates a new station and then replies with another AUTH frame. However, if sta allocations fails the host should send a DEAUTH frame instead to tell the other end that something went wrong.

mac80211: add supported rates change notification in IBSS

2012-08-20T11:31:43Z

In IBSS it is possible that the supported rates set for a station changes over time (e.g. it gets first initialised as an empty set because of no available information about rates and updated later). In this case the driver has to be notified about the change in order to update its internal table accordingly (if needed). This behaviour is needed by all those drivers that handle rc internally but leave stations management to mac80211 Reported-by: Gui Iribarren Signed-off-by: Antonio Quartulli [Johannes - add docs, validate IBSS mode only, fix compilation] Signed-off-by: Johannes Berg

mac80211: use oper_channel in ibss

2012-07-31T14:18:52Z

Using hw.conf.channel is wrong as it could be the temporary channel if any function like the beacon get function is called while scanning or during other temporary out-of-channel activities. Use oper_channel instead. Signed-off-by: Johannes Berg

mac80211: clean up debugging

2012-06-24T09:32:29Z

There are a few things that make the logging and debugging in mac80211 less useful than it should be right now: * a lot of messages should be pr_info, not pr_debug * wholesale use of pr_debug makes it require *both* Kconfig and dynamic configuration * there are still a lot of ifdefs * the style is very inconsistent, sometimes the sdata->name is printed in front Clean up everything, introducing new macros and separating out the station MLME debugging into a new Kconfig symbol.
