Hi,
it seems there is demand for WPA-None support (at least there is a PR,
and I've been ask about it), so, I went ahead and implemented it.
I've done tests with 3 clients using attached wpa_supplicant.conf and
couldn't find any kind of issues/regressions.
Summary of the changes:
- WPA-None requires ap_scan=2:
The major difference between ap_scan=1 (default) and 2 is, that no
IEEE80211_IOC_SCAN* ioctls/functions are called, though, there is a
dependency on those. For example the call to wpa_driver_bsd_scan()
sets the interface UP, this never happens, therefore the interface
must be marked up in wpa_driver_bsd_associate(). IEEE80211_IOC_SSID
also is not called, which means that the SSID has not been set prior
to the IEEE80211_MLME_ASSOC call.
- WPA-None has no support for sequence number updates, it doesn't make
sense to check for replay violations..
- I had some crashes right after the switch to RUN state, issue is
that sc->sc_lastrs was not yet defined.

Hi folks,
A couple of days ago I sent a mail to this list detailing an issue I
have. To summarize: every once in a while my ::1 address on lo0 is
replaced with another ipv6-address that's configured on lo3 and used in
a child jail of a jail. I've been digging a bit through the FreeBSD
source code and found a possible spot where this may occur.
In the function in6_selectsrc() in /sys/netinet6/in6_src.c the following
code can be found:
TAILQ_FOREACH(ia, &V_in6_ifaddrhead, ia_link) {
...
prison_local_ip6(cred, &ia->ia_addr.sin6_addr,
(inp != NULL &&
(inp->inp_flags & IN6P_IPV6_V6ONLY) != 0)) != 0)
continue;
...
}
prison_local_ip6() appears to replace a loopback address with a jail's
main address:
if (IN6_IS_ADDR_LOOPBACK(ia6)) {
bcopy(&pr->pr_ip6[0], ia6, sizeof(struct in6_addr));
...
The way I read this code is that it replaces the interface address 'ia'
when it is a loopback address with the prison's main address.
Can anyone with more clue about this code tell if I read this correctly
and possibly even help with fixing the problem if that is the case?
Thanks,
Pieter

thanks!
yep, i understood the stacks in from vr0 to the bridge. but yes,
short-cutting the diagram was a bad. thanks for the fix.
it's the bridge that worries me. took me a while to make it work

ok this is similar to my setup in some ways.
but the picture is wrong,
remember that vr0 is not (or at least should not be) part of the bridge.
the real picture is:

where [R] is the IP forwarding code (i.e routing not bridging)

my profile is pppoe which is shown below
It's not completely different from yours but seems to work

I can't help you withthe bridge part but it should be ok I think.

pppoe:
set device PPPoE:vr1
set redial 10.3 10000
set speed 115200 #not really intersting
set timeout 0 # Never time out
disable dns
disable ipv6cp
disable sroutes
set authname heyitsme
set authkey really?
set login
enable lqr
set ifaddr X.X.X.X/32 0.0.0.0/0 255.255.255.255 0.0.0.0
add default HISADDR # Add a (sticky) default route

You are reading this correctly. Good catch! I'll look how to fix that.
