* Add os_exec() helper to run external programsJouni Malinen2015-10-203-0/+68

* P2P: Validate SSID element length before copying itJouni Malinen2015-10-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | This fixes a possible memcpy overflow for P2P dev->oper_ssid in p2p_add_device(). The length provided by the peer device (0..255 bytes) was used without proper bounds checking and that could have resulted in arbitrary data of up to 223 bytes being written beyond the end of the dev->oper_ssid[] array (of which about 150 bytes would be beyond the heap allocation) when processing a corrupted management frame for P2P peer discovery purposes. This could result in corrupted state in heap, unexpected program behavior due to corrupted P2P peer device information, denial of service due to process crash, exposure of memory contents during GO Negotiation, and potentially arbitrary code execution. Thanks to Google security team for reporting this issue and smart hardware research group of Alibaba security team for discovering it.

* P2P: Fix broken rx action frame handling (INTERNAL-SQUASH)Eyal Shapira2012-11-132-1/+5
| | | | | | | | | | | | | | | | | | | | | | Commit "P2P: Fix duplicate handling of rx action frames" went too far and dropped any rx action frames arriving on the GO interface. It assumed that any action frames were duplicated and received on both GO interface and P2P device interface. This is wrong as some actions frames like P2P presence request are sent to the GO interface address and won't be duplicated. The root cause of the duplication lies within the Rx path in mac80211 in Johannes` patch "mac80211: accept public action frames with mismatched BSSID". When wpa_s works with a separate group interface this creates a duplicated Rx on both the P2P dev interface and the GO interface. Fix the issue by canceling the duplication in wpa_s and discarding public action frames with unmatching bssid arriving on a dedicated GO interface (This should be squashed with "P2P: Fix duplicate handling of rx action frames") Signed-off-by: Eyal Shapira <eyal@wizery.com>

* P2P: cancel action frame offchan wait after recv go neg resp (UPSTREAM)Eyal Shapira2012-11-021-1/+1
| | | | | | | | | | | A wait of 200ms is configured after sending the go neg request. The go neg process can end quickly within less than 200ms. If this wait isn't canceled it can cause the beaconing of the GO to start while mac80211 is still off channel on the listen channel and this may cause beaconing on the wrong channel if oper channel is different from the listen channel.

* P2P: cancel action frame offchan wait after recv go neg confEyal Shapira2012-10-241-0/+1
| | | | | | | | | | | The missing call to scan_action_done keeps us offchan on the listen channel for 250ms following sending go neg resp. In case the oper channel is different from the listen channel and we're GO a race could lead to start beaconing while offchan. This causes the beacons to go out on the listen channel instead of the oper channel. Signed-off-by: Eyal Shapira <eyal@wizery.com>

* nl80211: make unicast RX filter always match STA iface mac (ANDROID)Eyal Shapira2012-09-131-4/+4
| | | | | | | | | | | | | | This is part of changing the RX filters configuration to being global and not dependent on the interface context. RX filter #0 should point to a filter matching any unicast frame sent to the STA (wlan0) mac. The configuration is done by querying the mac address of the interface. As we now have reconfiguration of filters done from the context of the p2p interface filter #0 would get reconfigured with the P2P dev mac. Avoid this by hard coded querying for the mac of wlan0 when creating the pattern for RX filter #0. Signed-off-by: Eyal Shapira <eyal@wizery.com>
* nl80211: reconfigure RX filters whenever a new interface is added (ANDROID)Eyal Shapira2012-09-131-0/+35
| | | | | | | | | | This is used to reconfigure RX filters to include a new filter whenever the P2P group interface is added. The new filter matches any unicast frame sent to a dest mac which matches the P2P group interface mac. This is important as otherwise we wouldn't allow any data frames through to this interface.

* nl80211: support configuring RX filters dynamically (ANDROID)Eyal Shapira2012-09-121-5/+128
| | | | | | | | | | | | The current RX filters are statically defined and can only be enabled or disabled by the DRIVER RX-FILTER commands. Add support to add or remove RX filters "on the fly" from within wpa_s code so we can use this to add an RX filter matching unicast packets going to the new P2P interface mac. Whenever the filters change the whole list of filters needs to be configured to the kernel. Signed-off-by: Eyal Shapira <eyal@wizery.com>
* nl80211: make rx filters config global (ANDROID)Eyal Shapira2012-09-121-12/+24
| | | | | | | | | | | | The RX filters (wowlan) configuration is per interface but this doesn't reflect the state in the kernel where it's per hw device (effectively in Android global). In JB this is more important as wpa_s uses up to 3 different interfaces when running P2P+STA. Also, fix a minor bug in nl80211_toggle_wowlan_trigger where the wpa_s wowlan state changed even if configuring the kernel failed. Signed-off-by: Eyal Shapira <eyal@wizery.com>

* Make copies basic_rates list more usefulJouni Malinen2012-09-071-0/+2
| | | | | | | | | | | Commit e5693c4775bae65faa960f80889f98b0a6cb2e1c added a copy of the determined basic rate set into struct hostapd_iface, but did not actually copy the terminating -1 value. This could be problematic if something were to actually try to use this list since would be no way to know what is the last entry in the list. Fix this by copying the terminating value.

* P2P: prefer operating channels where HT40 is possibleArik Nemtsov2012-09-041-0/+15
| | | | | | | | When no other user preference is specified, opt to use an operating channel that allows HT40 operation. This way, if driver capabilities and regulatory constraints allow, we might enjoy increased bandwidth. Signed-hostap: Arik Nemtsov <arik@wizery.com>
* P2P: always re-select oper channel if not hard codedArik Nemtsov2012-09-041-1/+16
| | | | | | | | | | | Since the operating channel is randomly set to 1/6/11 on init, which is always in the channel intersection, we were effectively ignoring the set of p2p preferred channels. Fix this by trying to get the best channel we can, unless the user hard coded the operating channel in the configuration file. Fall back to the initial randomly selected channel if a better one cannot be chosen. Signed-hostap: Arik Nemtsov <arik@wizery.com>
* P2P: Use larger GO config timeout if HT40 is usedJouni Malinen2012-09-045-3/+29

* Remove default ACM=1 from AC_VO and AC_VIJouni Malinen2012-09-041-2/+2
| | | | | | | | | | There is no need to mandate admission control (ACM=1) by default, so clear that flag in the case the configuration file does not specify wmm_ac_{vo,vi}_acm value. This gets closer to the values mentioned in the sample hostapd.conf file and reduces the need to specify WMM parameters in the configuration file for most common use cases.

* AP: configure basic rates from iface and not confArik Nemtsov2012-09-041-1/+1
| | | | | | | | | The conf doesn't contain any basic rates in some cases. Most notably, when starting a p2p GO in 5Ghz. Use the iface rates which are initialized in hostapd_prepare_rates() to the conf rates or set to default values if no conf values exist. Signed-hostap: Arik Nemtsov <arik@wizery.com>
* Add P2P IEs to probe requests only when in P2P (UPSTREAM)Eyal Shapira2012-08-132-0/+17
| | | | | | | | | | | | The current code caused P2P and consquently WPS IEs to be added to any probe as the check was for non null global->p2p. global->p2p gets set whenever P2P is initialized globally and that occurs on the first interface init. Fix this by indicating wps is in use only when in active P2P discovery or connection establishement.

* P2P: Increase GO Negotiation timeoutsJouni Malinen2012-08-122-3/+3
| | | | | | | | | | | | | | | | | | | | | | p2p_set_timeout() calls in GO Neg Req/Resp TX callbacks used timeout of 100 ms which is the value given in the P2P specification for GO Negotiation, but this was actually shorter than the wait-for-offchannel-TX value (200 ms) used for the driver call. In addition, it looks like some devices (e.g., Galaxy Nexus with JB image) can take longer time to reply to GO Negotiation Response (somewhere between 200 and 250 ms has been observed). Increase the wait-for-GO-Neg-Resp timeout from 100 ms to 200 ms if GO Negotiation Request frame was acknowledged (this matches with the offchannel wait timeout that used previously). The no-ack case is left at 100 ms since we use GO Negotiation Request frame also to discover whether the peer is on its Listen channel. Increase the wait-for-GO-Neg-Conf timeout from 100 ms to 250 ms (and increase the offchannel wait timeout to matching 250 ms) as a workaround for devices that take over 200 ms to reply to GO Negotiation Response.

* nl80211: avoid using another interface for P2P GO (INTERNAL)Eyal Shapira2012-08-021-1/+0
| | | | | | | | | | | | | | | | | Relevant for wl6/7 only, we need to figure out the wl8 MR case. We now declare iface combinations in wlcore due to cfg80211 enforcement of that. Since we declare support for concurrent STA and P2P_GO, wpa_s would like to use another interface for GO. However, since we don't really support P2P_GO so well in MR but we do want to enable it in MR, prevent wpa_s from using P2P concurrent mode. This should be removed once we support P2P_GO properly in MR. [Arik - should be changed to a configuration parameter to wpa_s, and the current default should be preserved] Signed-off-by: Eyal Shapira <eyal@wizery.com>

* P2P: Improve scan results handling (BRCM)Eyal Shapira2012-08-022-0/+25
| | | | | | | | | | | Avoid reporting scan results to the application in case a P2P search is in progress as there will be many events but the scan is only done on channels 1,6,11.

| | | | | | | | | | | | | | p2p find can now defer starting the p2p scan due to an ongoing scan on a different interface. Relying on p2p_cb_on_scan_complete which is a per interface flag is wrong here and we won't resume the p2p find in case the scan wasn't on the same interface (which is the case in Android JB). Fix this by relying on the global p2p state instead.
