| | | | | | | | | | | | | | Regardless if a verbose scan is required or not, we'd still want to display the full SSID name by default so use the IEE80211_NWID_LEN constant to set the value to use instead.

* ifconfig(8): Attempt to render non-printable sequences w/ UTF-8 EnvironmentKyle Evans2018-06-281-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently ifconfig(8) only prints the hex representation of ssid names with non-ASCII characters. Many modern terminals are able to properly render non-ASCII characters. This change checks if the terminal charmap is UTF-8, and if so, will render the characters, rather than the hex value. This behavior is circumvented by running ifconfig(8) in a non-UTF8 locale; e.g. C or POSIX. It was pointed out by kp@ during the review that APs have the option to broadcast whether their SSIDs may be interpreted as UTF-8. Ideally, we would honor this and only attempt this behavior if it's so-broadcasted by the AP. However, a sample survey showed that hostapd will advertise this if indicated in config but it doesn't seem to be so common in the AP market, so this would be effectively useless as we'll rarely know if the SSID should be renderable as UTF-8. Despite this, it was decided to be OK with this anyways- there's a straightforward path to doing it the right way based on advertisement by AP if we need to go that route, and one can revert to old behavior easily enough at runtime if we get it wrong.

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-1/+3
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change default regulatory domain from DEBUG (no limitations; exposes all device channels) to FCC; as a result, newly created wireless interface with default settings will have less chances to violate country-specific regulations. This change will not affect drivers with pre-initialized regdomain structure (currentry ath(4) and mwl(4)); in that case, the default channel list must correspond to the default regdomain / country setting. You can switch to another regdomain / country via corresponding ifconfig(8) options; the driver must implement ic_getradiocaps() method to restore full channel list. Full country / regdomain list may be obtained via 'ifconfig <iface> list countries' command. Example: change country to Germany: ifconfig wlan0 down # all wlans on the device must be down ifconfig wlan0 country DE ifconfig wlan0 up # wpa_supplicant(8), dhclient(8) etc At the creation time: ifconfig wlan0 create wlandev wpi0 country DE To make changes permanent add the following line to the rc.conf(5): create_args_wlan0="country DE" Tested with - Intel 3945BG (wpi(4)). - WUSB54GC (rum(4)).
