* package: fix segfault of iwinfo.scanlist("radio0").Jo-Philipp Wich2014-08-121-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | This is a bug revealed in r41830. First, the static variable `char nif[IFNAMSIZ]` of nl80211_phy2ifname() would be zeroed out if the argument is "wlan0" or the like. This will happen in the following call stack. nl80211_get_scanlist("radio0", buf, len); nl80211_phy2ifname("radio0") // return static var nif with content "wlan0" nl80211_get_scanlist(nif, buf, len); // tail call nl80211_get_mode(nif); nl80211_phy2ifname(nif); // zero out nif Later we try nl80211_ifadd("") which was supposed to create interface "tmp.", but that won't happen because nl80211_msg() will put an invalid ifidx 0 to the nlmsg. Then iwinfo_ifup() and iwinfo_ifdown() would fail and happily nl80211_get_scanlist() returned 0 and left *len undefined. Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com> SVN-Revision: 42151

* iwinfo: avoid creating tmp.* ifaces for scanningJo-Philipp Wich2014-07-251-2/+22
| | | | | | | | | | | | If the iface to scan on already is in ad-hoc, station or monitor mode then do not spawn a temporary iface. Also preventively disable IPv6 on temporary ifaces before bringing them up to avoid potential security issues. Signed-off-by: Jo-Philipp Wich <jow@openwrt.org> SVN-Revision: 41830
* iwinfo: continue scanning even if temporary mac cannot be changedJo-Philipp Wich2014-07-251-2/+1
| | | | | | | | | | So far iwinfo aborted a wifi scan attempt if the mac of the spawned interface could not be changed. Change the code to try anyway - this should fix wifi scanning on RaLink devices. Signed-off-by: Jo-Philipp Wich <jow@openwrt.org> SVN-Revision: 41826

* libiwinfo: ignore log messages from wpa_supplicant while scanningJo-Philipp Wich2013-06-091-16/+47
| | | | | | | | | | | | | | | wpa_supplicant may send log and event messages intermixed with the expected scan results. This makes "iwinfo wlan0 scan" and LuCI "site survey" display nothing when many AP's are around. Eliminate the CTRL-EVENT-BSS-ADDED events, interspersed log messages, lines with unexpected format. Increase timeout to handle the max number of channels (2.4, 3.6, 4.9, 5 GHz). Insure receive buffer is null-terminated. Signed-off-by: Jean-Pierre Tosoni <jp.tosoni@acksys.fr> SVN-Revision: 36888
