[Cerowrt-devel] segfault in radio configuration

cero 3.10.32-12, on a 3800

I had a power outage (power strip bumped), and the wndr rebooted, and came
up without wireless radios running.  I ssh'd in and found this in the logs:

Wed Mar 26 14:33:41 2014 user.notice root: ingress shaping activated
Wed Mar 26 14:33:41 2014 kern.info kernel: [   27.777343] IPv6:
ADDRCONF(NETDEV_UP): sw00: link is not ready
Wed Mar 26 14:33:41 2014 daemon.notice netifd: radio0 (1556): Segmentation
fault (core dumped)
Wed Mar 26 14:33:41 2014 daemon.notice netifd: radio0 (1556): cat: can't
open '/var/run/wifi-phy0.pid': No such file or directory
Wed Mar 26 14:33:41 2014 kern.info kernel: [   27.839843] cfg80211: Calling
CRDA for country: US
Wed Mar 26 14:33:42 2014 kern.info kernel: [   27.859375] cfg80211:
Regulatory domain changed to country: US

Something appears to have segfaulted trying to set the country-code to FR.
 I changed /etc/config/wireless to use the US country code, restarted
networking, and the radios came up just fine.

Any ideas (and anyone want the core?)

There were several segfault bugs fixed in netifd since that release.
There was also an issue with correctly parsing the wireless regdb.
Please upgrade. You've got heartbleed, too.

What's the recommended version?

Only visible to me, though... This doesn't do outbound ssl, and only my
laptop talks to it.

3.10.36-3 and later are patched for heartbleed. Regrettably we are still
tracking down the wifi bug that was occuring frequently in recent releases,
and although I *think* it's harder to hit in 3.10.36-4, it can still be hit.
