Bjoern A. Zeeb bfb202c455 WPA: driver_bsd.c: backout upstream IFF_ change and add logging This reverts the state to our old supplicant logic setting or clearing IFF_UP if needed. In addition this adds logging for the cases in which we do (not) change the interface state. Depending on testing this seems to help bringing WiFi up or not log any needed changes (which would be the expected wpa_supplicant logic now). People should look out for ``(changed)`` log entries (at least if debugging the issue; this way we will at least have data points). There is a hypothesis still pondered that the entire IFF_UP toggling only exploits a race in net80211 (see further discssussions for more debugging and alternative solutions see D38508 and D38753). That may also explain why the changes to the rc startup script [1] only helped partially for some people to no longer see the continuous CTRL-EVENT-SCAN-FAILED. It is highly likely that we will want further changes and until we know for sure that people are seeing ''(changed)'' events this should stay local. Should we need to upstream this we'll likely need #ifdef __FreeBSD__ around this code.

file for more instructions.


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).
