When calling circuit_build_times_shuffle_and_store_array, we were
passing a uint32_t as an int. arma is pretty sure that this can't
actually cause a bug, because of checks elsewhere in the code, but
it's best not to pass a uint32_t as an int anyway.
Found by doorss; fix on 0.2.2.4-alpha.
Left circuit_build_times_get_bw_scale() uncommented because it is in the wrong
place due to an improper bug2317 fix. It needs to be moved and renamed, as it
is not a cbt parameter.
To quote arma: "So instead of stopping your CBT from screaming, you're just
going to throw it in the closet and hope you can't hear it?"
Yep. The log message can happen because at 95% point on the curve, we can be
way beyond the max timeout we've seen, if the curve has few points and is
shallow.
Also applied Nick's rule of thumb for rewriting some other notice log messages
to read like how you would explain them to a raving lunatic on #tor who was
shouting at you demanding what they meant. Hopefully the changes live up to
that standard.
If we got a signed digest that was shorter than the required digest
length, but longer than 20 bytes, we would accept it as long
enough.... and then immediately fail when we want to check it.
Fixes bug 2409; bug in 0.2.2.20-alpha; found by piebeer.
When we added support for separate client tls certs on bridges in
a2bb0bfdd5 we forgot to correctly initialize this when changing
from relay to bridge or vice versa while Tor is running. Fix that
by always initializing keys when the state changes.
Fixes bug 2433.
Our regular DH parameters that we use for circuit and rendezvous
crypto are unchanged. This is yet another small step on the path of
protocol fingerprinting resistance.
This patch imposes (very long) limits on the length of a line in a
directory document, and on the length of a certificate. I don't
think it should actually be possible to overrun these remotely,
since we already impose a maximum size on any directory object we're
downloading, but a little defensive programming never hurt anybody.
Roger emailed me that doorss reported these on IRC, but nobody seems
to have put them on the bugtracker.
