609065f165 DefecTor countermeasure: change server- and client-side DNS TTL clipping

Additionally, we move some defines to dns.h, and give them better
names.

5227ff4aad Remove redundant options checks for IPv6 preference conflicts 
It is no longer possible for the IPv6 preference options to differ from the
IPv6 usage: preferring IPv6 implies possibly using IPv6.

Also remove the corresponding unit test warning message checks.
(But keep the unit tests themselves - they now run without warnings.)

f4ebbf7567 fixup! Fix unit test failures in response to DNS hijacking. 2017-01-04 09:03:41 -05:00

c4a6b56cc1 Fix unit test failures in response to DNS hijacking. 
Some DNS NXDOMAIN hijackers hijack truly ridiculous domains, like
"invalid-stuff!!" or "1.2.3.4.5".  This would provoke unit test
failures where we used addresses like that to force
tor_addr_lookup() to fail.  The fix, for testing, is to mock
tor_addr_lookup() with a variant that always fails when it gets
a name with a !.

Fixes bugs 20862 and 20863.

04f21f0322 Remove abort handler from the backtrace generator 
The abort handler masks the exit status of the backtrace generator by
capturing the abort signal from the backtrace handler and exiting with
zero. Because the output of the backtrace generator is meant to be piped
to `bt_test.py`, its exit status is unimportant and is currently
ignored.

The abort handler calls `exit(3)` which is not asynchronous-signal-safe
and calling it in this context is undefined behavior [0].

Closes ticket 21026.
