Ok, I dodn't know that - thanks for pointing it out. In my setup here, SSIDs are always valid alphanumeric strings, and I was mislead by the comment that mentions the NULL-termination. > drivers/net/wireless/libertas$ grep lbs_deb_ * | grep ssid|grep '%s' > assoc.c: lbs_deb_join("current SSID '%s', ssid length %u\n", > assoc.c: lbs_deb_join("requested ssid '%s', ssid length %u\n", > assoc.c: lbs_deb_join("ADHOC_START: SSID '%s', ssid length %u\n", > scan.c: lbs_deb_wext("set_scan, essid '%s'\n", Those macros are stubbed out as nops in my setup, so they can unfortunately not be the reason. I'll dig deeper :) Thanks, Daniel -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
