This migrates away from SHA1, and provides further hash flooding
protection on top of the randomised siphash implementation.
Add unit tests to make sure that different inputs don't have the
same hash.
The wrong list was used when looking up expired intro points in a rend
service object causing what we think could be reachability issues and
triggering a BUG log.

exit-policy/reject-private lists the reject rules added by
ExitPolicyRejectPrivate. This makes it easier for stem to
display exit policies.
Add unit tests for getinfo exit-policy/*.

(But it won't work on some systems without IPv4/IPv6 localhost
(some BSD jails) by design, to avoid creating sockets on routable
IP addresses. However, those systems likely have the AF_UNIX socketpair,
which tor prefers.)
Fixes bug #17638; bugfix on a very early tor version,
earlier than 22dba27d8d (23 Nov 2004) / svn:r2943.
Patch by "teor".
Make unit tests pass on IPv6-only systems, and systems without
localhost addresses (like some FreeBSD jails).
Fixes:
* get_if_addrs_ifaddrs: systems without localhost
* get_if_addrs_ioctl: only works on IPv4 systems
* socket: check IPv4 and IPv6, skip on EPROTONOSUPPORT
* socketpair_ersatz: uses IPv4, skip on EPROTONOSUPPORT
Fixes bug #17632; bugfix on unit tests in 0.2.7.3-rc.
c464a36772 was a partial fix for this issue in #17255;
it was released in unit tests in 0.2.7.4-rc.

Long ago we used to call connection_ap_handshake_attach_circuit()
only in a few places, since connection_ap_attach_pending() attaches
all the pending connections, and does so regularly. But this turned
out to have a performance problem: it would introduce a delay to
launching or connecting a stream.
We couldn't just call connection_ap_attach_pending() every time we
make a new connection, since it walks the whole connection list. So
we started calling connection_ap_attach_pending all over, instead!
But that's kind of ugly and messes up our callgraph.
So instead, we now have connection_ap_attach_pending() use a list
only of the pending connections, so we can call it much more
frequently. We have a separate function to scan the whole
connection array to see if we missed adding anything, and log a
warning if so.
Closes ticket #17590
Mark fallback directory mirrors as "too busy" when they return
a 503 response. Previously, the code just marked authorities as busy.
Unless clients set their own fallback directories, they will never see
this bug. (There are no default fallbacks yet.)
Fixes bug 17572; bugfix on 5c51b3f1f0 released in 0.2.4.7-alpha.

Without this check, we potentially look up to 3 characters before
the start of a malloc'd segment, which could provoke a crash under
certain (weird afaik) circumstances.
Fixes 17404; bugfix on 0.2.6.3-alpha.
* Don't assume that every test box has an IPv4 address
* Don't assume that every test box has a non-local address
Resolves issue #17255 released in unit tests in 0.2.7.3-rc.
Now that x509_get_not{Before,After} are functions in OpenSSL 1.1
(not yet releasesd), we need to define a variant that takes a const
pointer to X509 and returns a const pointer to ASN1_time.
Part of 17237. I'm not convinced this is an openssl bug or a tor
bug. It might be just one of those things.
When logging to syslog, allow a tag to be added to the syslog identity
("Tor"), i.e. the string prepended to every log message. The tag can be
configured by setting SyslogIdentityTag and defaults to none. Setting
it to "foo" will cause logs to be tagged as "Tor-foo". Closes: #17194.
Warn when the state file was last written in the future.
Tor doesn't know that consensuses have expired if the clock is in the past.
Patch by "teor". Implements ticket #17188.
Ensure that either a valid address is returned in address pointers,
or that the address data is zeroed on error.
Ensure that free_interface_address6_list handles NULL lists.
Add unit tests for get_interface_address* failure cases.
Fixes bug #17173.
Patch by fk/teor, not in any released version of tor.
Use environment variables instead. This repairs 'make distcheck',
which was running into trouble when it tried to chmod the generated
scripts.
Fixes 17148.
