Erk! we shouldn't do this for every login!
And we arguably should have a limit on the
number of nodes scanned, anyway.
The code in uint32 do_reseed says:
We use /dev/urandom as a read of /dev/random can block if
the entropy pool dries up. This leads clients to timeout
or be very slow on connect.
I'd suggest adding an integer counter and a
limit to do_dirrand: in place of
while ((p = readdirname(dp)))
just put in
for (i=0; p = readdirname(dp) && i < XXX; i++)
A side comment: the size of items in a Solaris /dev
clusters around 25 characters, and so isn't a really
good source of randomness.
