Re: [Cerowrt-devel] archer c7 v2, policing, hostapd, test openwrt build

I don't remember what I did. I remember sticking something in to
improve entropy, and ripping out a patch to hostapd that tried to
manufacture it.

right now I'm merely trying to stablize the new bits - dnssec for
dnsmasq 2.73rc1, babel-1.6 (not in this build) with procd and
ipv6_subtrees and atomic updates, get someone F/T on the minstrel
stuff, and get heads down on per station queuing by mid april. I was
not expecting to make chaos calmer with the last at all and am still
not, and next up is getting some profiling infrastructure in place
that actually works....

For general purposes, seed a good RNG once before first use, using /dev/urandom, then just keep pulling values from it as needed.  Or, if cryptographic quality is required, use an actual crypto library’s RNG.
