Save the ids of the netlink trigger scan commands that we send and cancel them in scan_ifindex_remove to fix a race leading to a segfault. The segfault would happen every time if scan_ifindex_remove was called in the same main loop iteration in which we sent the command, on shutdown: ^CTerminate src/netdev.c:netdev_free() Freeing netdev wlan3[6] src/device.c:device_disassociated() 6 src/device.c:device_enter_state() Old State: connected, new state: disconnected src/device.c:device_enter_state() Old State: disconnected, new state: autoconnect src/scan.c:scan_periodic_start() Starting periodic scan for ifindex: 6 src/device.c:device_free() src/device.c:bss_free() Freeing BSS 02:00:00:00:00:00 src/device.c:bss_free() Freeing BSS 02:00:00:00:01:00 Removing scan context for ifindex: 6 src/scan.c:scan_context_free() sc: 0x5555557ca290 src/scan.c:scan_notify() Scan notification 33 src/netdev.c:netdev_operstate_down_cb() netdev: 6, success: 1 src/scan.c:scan_periodic_done() src/scan.c:scan_periodic_done() Periodic scan triggered for ifindex: 1434209520 Program received signal SIGSEGV, Segmentation fault. 0x0000000000000064 in ??
