Two virtual wireless devices are instantiated during network devices initialization. A new flag (-wifi) is added that controls whether these virtual wifi devices are instantiated and configured during proc initialization. Also, two new pseudo syscalls are added: 1. syz_80211_inject_frame(mac_addr, packet, packet_len) -- injects an arbitrary packet into the wireless stack. It is injected as if it originated from the device identitied by mac_addr. 2. syz_80211_join_ibss(interface_name, ssid, ssid_len, mode) -- puts a specific network interface into IBSS state and joins an IBSS network. Arguments of syz_80211_join_ibss: 1) interface_name -- null-terminated string that identifies a wireless interface 2) ssid, ssid_len -- SSID of an IBSS network to join to 3) mode -- mode of syz_80211_join_ibss operation (see below) Modes of operation: JOIN_IBSS_NO_SCAN (0x0) -- channel scan is not performed and syz_80211_join_ibss waits until the interface reaches IF_OPER_UP. JOIN_IBSS_BG_SCAN (0x1) -- channel scan is performed (takes ~ 9 seconds), syz_80211_join_ibss does not await IF_OPER_UP. JOIN_IBSS_BG_NO_SCAN (0x2) -- channel scan is not performed, syz_80211_join_ibss does not await IF_OPER_UP. Local testing ensured that these syscalls are indeed able to set up an operating network and inject packets into mac80211. |
