6215ebb266 Reduce log severity for unused ClientTransportPlugin lines
Tor Browser includes several ClientTransportPlugin lines in its
torrc-defaults file, leading every Tor Browser user who looks at her
logs to see these notices and wonder if they're dangerous.

3c2c6a6116 In routerlist_assert_ok(), check r2 before taking &(r2->cache_info)
Technically, we're not allowed to take the address of a member can't
exist relative to the null pointer.  That makes me wonder how any sane
compliant system implements the offsetof macro, but let's let sleeping
balrogs lie.

962765a35d Don't list relays w/ bw estimate of 0 in the consensus
This implements a feature from bug 13000. Instead of starting a bwauth
run with this wrong idea about their bw, relays should do the self-test
and then get measured.
2014-09-02 18:55:01 -04:00
Sebastian Hahn
14abf1c3f1 Don't delay uploading a new desc if bw estimate was 0
When a tor relay starts up and has no historical information about its
bandwidth capability, it uploads a descriptor with a bw estimate of 0.
It then starts its bw selftest, but has to wait 20 minutes to upload the
next descriptor due to the MAX_BANDWIDTH_CHANGE_FREQ delay. This change
should mean that on average, relays start seeing meaningful traffic a
little quicker, since they will have a higher chance to appear in the
consensus with a nonzero bw.

00ffccd9a6 Another clang analyzer complaint wrt HT_GENERATE
We're calling mallocfn() and reallocfn() in the HT_GENERATE macro
with the result of a product.  But that makes any sane analyzer
worry about overflow.

This patch keeps HT_GENERATE having its old semantics, since we
aren't the only project using ht.h.  Instead, define a HT_GENERATE2
that takes a reallocarrayfn.

setting it to 0 on success.  Also add a goto which was missing: its
