* 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.
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.
This allows builds on machines with a crippled openssl to fail early
during configure. Bugfix on 0.2.7.1-alpha, which introduced the
requirement for ECC support. Fixes bug 17109.
Advise users how to configure separate IPv4 and IPv6 exit
policies in the manpage and sample torrcs.
Related to fixes in ticket #16069 and #17027. Patch by "teor".
Patch on 2eb7eafc9d and a96c0affcb (25 Oct 2012),
released in 0.2.4.7-alpha.
src/test/test_policy.c:
Merged calls to policies_parse_exit_policy by adding additional arguments.
fixup to remaining instance of ~EXIT_POLICY_IPV6_ENABLED.
Compacting logic test now produces previous list length of 4, corrected this.
src/config/torrc.sample.in:
src/config/torrc.minimal.in-staging:
Merged torrc modification dates in favour of latest.
ExitPolicyRejectPrivate now rejects more local addresses by default:
* the relay's published IPv6 address (if any), and
* any publicly routable IPv4 or IPv6 addresses on any local interfaces.
This resolves a security issue for IPv6 Exits and multihomed Exits that
trust connections originating from localhost.
Resolves ticket 17027. Patch by "teor".
Patch on 42b8fb5a15 (11 Nov 2007), released in 0.2.0.11-alpha.
In previous versions of Tor, ExitPolicy accept6/reject6 * produced
policy entries for IPv4 and IPv6 wildcard addresses.
To reduce operator confusion, change accept6/reject6 * to only produce
an IPv6 wildcard address.
Resolves bug #16069.
Patch on 2eb7eafc9d and a96c0affcb (25 Oct 2012),
released in 0.2.4.7-alpha.
Tor now warns when ExitPolicy lines occur after accept/reject *:*
or variants. These lines are redundant, and were always ignored.
Partial fix for ticket 16069. Patch by "teor".
Patch on 2eb7eafc9d and a96c0affcb (25 Oct 2012),
released in 0.2.4.7-alpha.
When parsing torrc ExitPolicies, we now warn if:
* an IPv4 address is used on an accept6 or reject6 line. The line is
ignored, but the rest of the policy items in the list are used.
(accept/reject continue to allow both IPv4 and IPv6 addresses in torrcs.)
* a "private" address alias is used on an accept6 or reject6 line.
The line filters both IPv4 and IPv6 private addresses, disregarding
the 6 in accept6/reject6.
When parsing torrc ExitPolicies, we now issue an info-level message:
* when expanding an accept/reject * line to include both IPv4 and IPv6
wildcard addresses.
In each instance, usage advice is provided to avoid the message.
Partial fix for ticket 16069. Patch by "teor".
Patch on 2eb7eafc9d and a96c0affcb (25 Oct 2012),
released in 0.2.4.7-alpha.
Add get_interface_address[6]_list by refactoring
get_interface_address6. Add unit tests for new and existing functions.
Preparation for ticket 17027. Patch by "teor".
Patch on 42b8fb5a15 (11 Nov 2007), released in 0.2.0.11-alpha.
This controls the circuit dirtyness reset behavior added for Tor
Browser's user experience fix (#15482). Unlike previous iterations
of this patch, the tunable actually works, and is documented.
(These inputs are possible when Shadow starts the world at time_t 0,
and breaks our assumption that Tor didn't exist in the 1970s.)
Fixes regression introduced in 241e6b09. Fixes#16980.
When this is set, and Tor is running as a relay, it will not
generate or load its secret identity key. You can manage the secret
identity key with --keygen. Implements ticket 16944.
In a nutshell, since a circuit can not exit at its entry point, it's very
easy for an attacker to find the hidden service guard if only one EntryNodes
is specified since for that guard, the HS will refuse to build a rendezvous
circuit to it.
For now, the best solution is to stop tor to allow a single EntryNodes for
an hidden service.
Fixes#14917

Make "bridges+hs" the default test network. This tests almost all
tor functionality during make test-network, while allowing tests
to succeed on non-IPv6 systems.
Requires chutney commit 396da92 in test-network-bridges-hs.
Closes tickets 16945 (tor), 16946 (chutney) . Patches by "teor".
Previously we'd put these strings right on the controllers'
outbufs. But this could cause some trouble, for these reasons:
1) Calling the network stack directly here would make a huge portion
of our networking code (from which so much of the rest of Tor is
reachable) reachable from everything that potentially generated
controller events.
2) Since _some_ events (EVENT_ERR for instance) would cause us to
call connection_flush(), every control_event_* function would
appear to be able to reach even _more_ of the network stack in
our cllgraph.
3) Every time we generated an event, we'd have to walk the whole
connection list, which isn't exactly fast.
This is an attempt to break down the "blob" described in
http://archives.seul.org/tor/dev/Mar-2015/msg00197.html -- the set of
functions from which nearly all the other functions in Tor are
reachable.
Closes ticket 16695.
"option to prevent guard,exit,hsdir flag assignment"
"A node will never receive the corresponding flag unless
that node is specified in the
TestingDirAuthVote{Exit,Guard,HSDir} list, regardless of
its uptime, bandwidth, exit policy, or DirPort".
Patch modified by "teor": VoteOnHidServDirectoriesV2
is now obsolete, so TestingDirAuthVoteHSDir always
votes on HSDirs.
Closes ticket 14882. Patch by "robgjansen".

This probably requires the user to manually set CFLAGS, but should
result in a net gain on 32 bit x86. Enabling SSE2 support would be
possible on x86_64, but will result in slower performance.
Implements feature #16535.
Instead of having it call update_all_descriptor_downloads and
update_networkstatus_downloads directly, we can have it cause them to
get rescheduled and called from run_scheduled_events.
Closes ticket 16789.
The code was always in our Ed25519 wrappers, so enable it when using
the ed25519-donna backend, and deal with the mocking related
crypto_rand silliness.
Implements feature 16533.
