Hi,
this is a followup on the misc@ "problem with ral in hopstap mode on -current"
thread.
I had an AP running with a ral pci card in a soekris box with 4.2 for years.
About two weeks ago, I updated to -current. When the box is started, then the
ral card
works fine as AP for a while, but then suddenly stops. To fix the problem I had
to do a:
sh /etc/netstart ral0 on the AP, and wireless was back, working well, the
clients could connect again.
While the clients were unable to connect, the card itself on the AP looked fine
all the time:
$ ifconfig ral0
ral0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
lladdr 00:11:09:9a:9a:7e
priority: 4
groups: wlan
media: IEEE802.11 autoselect hostap (autoselect mode 11b hostap)
status: active
ieee80211: nwid brb.freifunk.net chan 1 bssid 00:11:09:9a:9a:7e 100dBm

inet6 fe80::211:9ff:fe9a:9a7e%ral0 prefixlen 64 scopeid 0x4
When the problem happened, I ran tcpdump -n -i ral0 -y IEEE802_11_RADIO -vvv,
and saw the output below.
>From some answers on misc@, others reported having seen similar problems
>starting to happen between
4.6 and 4.7. Sthen@ suggested to me to revert revision 1.56 of
src/sys/net80211/ieee80211_node.c
So I did.

So adding this rc=1 on Friday evening, now over the whole weekend, up to this
morning, my wireless is working stable now,
as it was before with the 4.2.
The commit log for the 1.56 revision was:
revision 1.56
date: 2010/02/17 18:34:37; author: damien; state: Exp; lines: +1 -2
Do not always create a new node when a beacon or a probe response
is received. The creation of a new node is already handled in
ieee80211_recv_probe_resp() when necessary.
This avoids creating empty nodes with wrong channels when beacons
are received on the wrong channel (overlapping channels).
Those empty nodes may also prevent the real node from being
discovered because of ieee80211_find_node_for_beacon() filtering.
This should prevent entries of the form:
nwid "" chan 3 bssid 00:01:02:03:04:05 0dB 54M
in "ifconfig if0 scan" output, like reported by Rivo Nurges.
So the change will probably reintroduce the problem that the change was
supposed to fix, and probably another different fix
to my problem or the problem above is needed.
I don't know what the real fix could be, but I'm willing to test anything that
gets thrown at me.
If more information is needed, let me know.
cheers,
Sebastian
