* cfg80211: add bss_type and privacy arguments in cfg80211_get_bss()Dedy Lansky2015-03-031-8/+78
| | | | | | | | | | | | | | | | | | | | 802.11ad adds new a network type (PBSS) and changes the capability field interpretation for the DMG (60G) band. The same 2 bits that were interpreted as "ESS" and "IBSS" before are re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid values are: "IBSS", "PBSS" (new) and "AP". In order to get the BSS struct for the new PBSS networks, change the cfg80211_get_bss() function to take a new enum ieee80211_bss_type argument with the valid network types, as "capa_mask" and "capa_val" no longer work correctly (the search must be band-aware now.) The remaining bits in "capa_mask" and "capa_val" are used only for privacy matching so replace those two with a privacy enum as well.

* cfg80211-wext: return -E2BIG when buffer can't hold full BSS entryJames Minor2015-02-281-76/+136
| | | | | | | | | | | | | | | | When using the wext compatibility code in cfg80211, part of the IEs can be truncated if the passed user buffer is large enough for part of the BSS but not large enough for all of the IEs. This can cause an EAP network to show up as a PSK network. Always return -E2BIG in this case to avoid truncating data. Since this changes the control flow, use an on-stack variable for a small buffer instead of allocating it.

* cfg80211-wext: export symbols only when neededJohannes Berg2015-02-281-2/+2
| | | | | | | | | | | | | | When a fully converted cfg80211 driver needs cfg80211-wext for userspace API purposes, the symbols need not be exported. When other drivers (orinoco/hermes or ipw2200) are enabled, they do need the symbols exported as they use them directly. Make those drivers select a new CFG80211_WEXT_EXPORT Kconfig symbol (instead of just CFG80211_WEXT) and export the functions only if requested - this saves about 1/2k due to the size of EXPORT_SYMBOL() itself.

* cfg80211: clarify BSS probe response vs. beacon dataJohannes Berg2014-08-261-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few possible cases of where BSS data came from: 1) only a beacon has been received 2) only a probe response has been received 3) the driver didn't report what it received (this happens when using cfg80211_inform_bss[_width]()) 4) both probe response and beacon data has been received Unfortunately, in the userspace API, a few things weren't there: a) there was no way to differentiate cases 1) and 4) above without comparing the data of the IEs b) the TSF was always from the last frame, instead of being exposed for beacon/probe response separately like IEs Fix this by i) exporting a new flag attribute that indicates whether or not probe response data has been received - this addresses (a) ii) exporting a BEACON_TSF attribute that holds the beacon's TSF if a beacon has been received iii) not exporting the beacon attributes in case (3) above as that would just lead userspace into thinking the data actually came from a beacon when that isn't clear To implement this, track inside the IEs struct whether or not it (definitely) came from a beacon.

| * cfg80211: allow RSSI compensationEmmanuel Grumbach2014-05-221-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Channels in 2.4GHz band overlap, this means that if we send a probe request on channel 1 and then move to channel 2, we will hear the probe response on channel 2. In this case, the RSSI will be lower than if we had heard it on the channel on which it was sent (1 in this case). The firmware / low level driver can parse the channel in the DS IE or HT IE and compensate the RSSI so that it will still have a valid value even if we heard the frame on an adjacent channel. This can be done up to a certain offset. Add this offset as a configuration for the low level driver. A low level driver that can compensate the low RSSI in this case should assign the maximal offset for which the RSSI value is still valid.

* cfg80211/mac80211: ignore signal if the frame was heard on wrong channelEmmanuel Grumbach2014-03-191-9/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 2.4Ghz band, the channels overlap since the delta between different channels is 5Mhz while the width of the receiver is 20Mhz (at least). This means that we can hear beacons or probe responses from adjacent channels. These frames will have a significant lower RSSI which will feed all kinds of logic with inaccurate data. An obvious example is the roaming algorithm that will think our AP is getting weak and will try to move to another AP. In order to avoid this, update the signal only if the frame has been heard on the same channel as the one advertised by the AP in its DS / HT IEs. We refrain from updating the values only if the AP is already in the BSS list so that we will still have a valid (but inaccurate) value if the AP was heard on an adjacent channel only. To achieve this, stop taking the channel from DS / HT IEs in mac80211. The DS / HT IEs is taken into account to discard the frame if it was received on a disabled channel. This can happen due to the same phenomenon: the frame is sent on channel 12, but heard on channel 11 while channel 12 can be disabled on certain devices. Since this check is done in cfg80211, stop even checking this in mac80211.

* cfg80211: send scan results from work queueJohannes Berg2014-02-061-15/+25
| | | | | | | | | | | | | | | | | | | | | | | | Due to the previous commit, when a scan finishes, it is in theory possible to hit the following sequence: 1. interface starts being removed 2. scan is cancelled by driver and cfg80211 is notified 3. scan done work is scheduled 4. interface is removed completely, rdev->scan_req is freed, event sent to userspace but scan done work remains pending 5. new scan is requested on another virtual interface 6. scan done work runs, freeing the still-running scan To fix this situation, hang on to the scan done message and block new scans while that is the case, and only send the message from the work function, regardless of whether the scan_req is already freed from interface removal. This makes step 5 above impossible and changes step 6 to be 5. scan done work runs, sending the scan done message As this can't work for wext, so we send the message immediately, but this shouldn't be an issue since we still return -EBUSY.

* cfg80211: don't "leak" uncompleted scansEliad Peller2013-12-051-13/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ___cfg80211_scan_done() can be called in some cases (e.g. on NETDEV_DOWN) before the low level driver notified scan completion (which is indicated by passing leak=true). Clearing rdev->scan_req in this case is buggy, as scan_done_wk might have already being queued/running (and can't be flushed as it takes rtnl()). If a new scan will be requested at this stage, the scan_done_wk will try freeing it (instead of the previous scan), and this will later result in a use after free. Simply remove the "leak" option, and replace it with a standard WARN_ON.

| | | | | | | | | | | | | | | Virtually all code paths in cfg80211 already (need to) hold the RTNL. As such, there's little point in having another four mutexes for various parts of the code, they just cause lock ordering issues (and much of the time, the RTNL and a few of the others need thus be held.)

* cfg80211: always check for scan end on P2P deviceJohannes Berg2013-03-241-3/+5
| | | | | | | | | | | | | | | | If a P2P device wdev is removed while it has a scan, then the scan completion might crash later as it is already freed by that time. To avoid the crash always check the scan completion when the P2P device is being removed for some reason. If the driver already canceled it, don't want and free it, otherwise warn and leak it to avoid later crashes. In order to do this, locking needs to be changed away from the rdev mutex (which can't always be guaranteed). For now, use the sched_scan_mtx instead, I'll rename it to just scan_mtx in a later patch. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

To understand this, consider a case where multiple BSS entries with the same channel and BSSID exist but have different SSID length. Then comparing against the probe response SSID length is bound to cause problems since the hidden one might be either zeroed out or zero-length.

This means that cmp_hidden_bss() needs to similarly return a number bigger than zero (use 1) instead of -1 when ie1 is bigger than ie2, which is the case if an ie2 byte is non-zero.
