Cy Schubert 953efa5b20 wpa_supplicant/hostapd: Fix uninitialized packet pointer on error The packet pointer (called packet) will remain uninitialized when pcap_next_ex() returns an error. This occurs when the wlan interface is shut down using ifconfig destroy. Adding a NULL assignment to packet duplicates what pcap_next() does. The reason we use pcap_next_ex() in this instance is because with pacp_next() when we receive a null pointer if there was an error or if no packets were read. With pcap_next_ex() we can differentiate between an error and legitimately no packets were received.

This package may include either wpa_supplicant, hostapd, or both. See
README file respective subdirectories (wpa_supplicant/README or
hostapd/README) for more details.

Source code files were moved around in v0.6.x releases and compared to
earlier releases, the programs are now built by first going to a
subdirectory (wpa_supplicant or hostapd) and creating build
configuration (.config) and running 'make' there (for Linux/BSD/cygwin
builds).
