https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264238 --- Comment #67 from Cy Schubert <cy@FreeBSD.org> --- wpa_driver_bsd_scan() calls set80211param() to set IEEE80211_IOC_ROAMING to IEEE80211_ROAMING_MANUAL immediately after setting mediaopt to STA. This is unconditional and if it fails it will issue a message to syslog. All this is passed to bsd_set80211() which calls ioctl at line 120: if (ioctl(drv->global->sock, SIOCS80211, &ireq) < 0) { wpa_printf(MSG_ERROR, "ioctl[SIOCS80211, op=3D%u, val=3D%u,= " "arg_len=3D%u]: %s", op, val, arg_len, strerror(errno)); return -1; } It is this error message we see in syslog, which may well be that it's fail= ing to set IEEE80211_ROAMING_MANUAL. A backtrace would be able to confirm this. The interesting thing we notice is that op contains various values. I've se= en -1 and 20 so far. op is passed to bsd_set80211() via set80211var() and set80211param(), each of which is called by numerous other callers. strerrorr(errno) is "invalid argument." The question remains, which caller is responsible for this? Once the user c= an obtain a dump, the backtrace will tell us which calling path is used and we= can discover where opt and val are set, because both of these are set many fram= es above this frame, thus will be on the stack. The user will need to provide wpa_supplicant.core from the binary I sent he= r -- because I put an abort() in place of the return. --=20 You are receiving this mail because: You are on the CC list for the bug.=
