The unit tests added in e033d5e90b got malformed_list added to
router_parse_addr_policy_item_from_string calls, but unit tests from
subsequent commits didn't get the extra argument until now.
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.

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.

Increase default boostrap time in test-network.sh to 30 seconds,

make test-network-all is Makefile target which verifies a series
of test networks generated using test-network.sh and chutney.
It runs IPv6 and mixed version test networks if the prerequisites are

Service descriptors are now generated regardless of the the
PublishHidServDescriptors option. The generated descriptors are stored
in the service descriptor cache.
The PublishHidServDescriptors = 1 option now prevents descriptor
publication to the HSDirs rather than descriptor generation.
We don't want to accept any work after one of our worker functions has
returned WQ_RPL_SHUTDOWN. This testcase currently fails, because we do
not actually stop any of the worker threads.
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.
Test that TestingDirAuthVote{Exit,Guard,HSDir}[Strict] work on
routersets matching all routers, one router, and no routers.
TestingDirAuthVote{Exit,Guard,HSDir} set the corresponding flag
on routerstatuses which match the routerset, but leave other flags
unmodified.
TestingDirAuthVote{Exit,Guard,HSDir}Strict clear the corresponding flag
on routerstatuses which don't match the routerset.
URI syntax (and DNS syntax) allows for a single trailing `.` to
explicitly distinguish between a relative and absolute
(fully-qualified) domain name. While this is redundant in that RFC 1928
DOMAINNAME addresses are *always* fully-qualified, certain clients
blindly pass the trailing `.` along in the request.
Fixes bug 16674; bugfix on 0.2.6.2-alpha.
The workqueue test help message has two issues. First, the message uses 4 space
indentation when 2 space indentation seems more common. Second, the help
message misses some options.
This commit fixes both issues.

The runtime sanity checking is slightly different from the optimized
basepoint stuff in that it uses a given implementation's self tests if
available, and checks if signing/verification works with a test vector
from the IETF EdDSA draft.
The unit tests include a new testcase that will fuzz donna against ref0,
including the blinding and curve25519 key conversion routines. If this
is something that should be done at runtime (No?), the code can be
stolen from there.
Note: Integrating batch verification is not done yet.
Integration work scavanged from nickm's `ticket8897_9663_v2` branch,
with minor modifications. Tor will still sanity check the output but
now also attempts to catch extreme breakage by spot checking the
optimized implementation vs known values from the NaCl documentation.
Implements feature 9663.
The following arguments change how chutney verifies the network:
--bytes n sends n bytes per test connection (10 KBytes)
--connections n makes n test connections per client (1)
--hs-multi-client 1 makes each client connect to each HS (0)
Requires the corresponding chutney performance testing changes.
Note: using --connections 7 or greater on a HS will trigger #15937.
Patch by "teor".
RFC 952 is approximately 30 years old, and people are failing to comply,
by serving A records with '_' as part of the hostname. Since relaxing
the check is a QOL improvement for our userbase, relax the check to
allow such abominations as destinations, especially since there are
likely to be other similarly misconfigured domains out there.
When I fixed#11243, I made it so we would take the digest of a
descriptor before tokenizing it, so we could desist from download
attempts if parsing failed. But when I did that, I didn't remove an
assertion that the descriptor began with "onion-key". Usually, this
was enforced by "find_start_of_next_microdescriptor", but when
find_start_of_next_microdescriptor returned NULL, the assertion was
triggered.
Fixes bug 16400. Thanks to torkeln for reporting and
cypherpunks_backup for diagnosing and writing the first fix here.
clang 3.7 complains that using a preprocessor directive inside

# The first commit's message is:

Also, have testing-level options to set the lifetimes and
expiration-tolerances of all key types, plus a non-testing-level
option to set the lifetime of any auto-generated signing key.
# The 2nd commit message will be skipped:
# fixup! Regenerate ed25519 keys when they will expire soon.
Extrainfo documents are now ed-signed just as are router
descriptors, according to proposal 220. This patch also includes
some more tests for successful/failing parsing, and fixes a crash
bug in ed25519 descriptor parsing.
An earlier version of these tests was broken; now they're a nicer,
more robust, more black-box set of tests. The key is to have each
test check a handshake message that is wrong in _one_ way.
When there are annotations on a router descriptor, the
ed25519-identity element won't be at position 0 or 1; it will be at
router+1 or router-1.
This patch also adds a missing smartlist function to search a list for
an item with a particular pointer.
This module implements a key-pinning mechanism to ensure that it's
safe to use RSA keys as identitifers even as we migrate to Ed25519
keys. It remembers, for every Ed25519 key we've seen, what the
associated Ed25519 key is. This way, if we see a different Ed25519
key with that RSA key, we'll know that there's a mismatch.
We persist these entries to disk using a simple format, where each
line has a base64-encoded RSA SHA1 hash, then a base64-endoded
Ed25519 key. Empty lines, misformed lines, and lines beginning with
a # are ignored. Lines beginning with @ are reserved for future
extensions.
Routers now use TAP and ntor onion keys to sign their identity keys,
and put these signatures in their descriptors. That allows other
parties to be confident that the onion keys are indeed controlled by
the router that generated the descriptor.
For prop220, we have a new ed25519 certificate type. This patch
implements the code to create, parse, and validate those, along with
code for routers to maintain their own sets of certificates and
keys. (Some parts of master identity key encryption are done, but
the implementation of that isn't finished)
As OpenSSL >= 1.0.0 is now required, ECDHE is now mandatory. The group
has to be validated at runtime, because of RedHat lawyers (P224 support
is entirely missing in the OpenSSL RPM, but P256 is present and is the
default).

The SH_LOG_COMPILER feature doesn't work with older automakes, and
those are still in use in many environments we want to support
development on, like Debian Stable.
Instead, use autoconf substitution to fill out the shebang lines on
the shell scripts, and an intermediate make target to make them
executable.
This is a bugfix on the patches for #15344. Bug not in any released

When we made assertions not get compiled in for the coverage case, we

For this to work bt_test.py now returns an exit code indicating success or
failure. Additionally, check-local and its specific dependencies are now
obsolete so they are removed.
The zero length keys test now requires the path to the Tor binary as the first
parameter to ensure the correct Tor binary is used without hard coding a path.
The wrapper script calls the zero length keys test for each test separately to
ensure the correct shell is used (as configured by autoconf). Another solution
would have been to place the tests into separate functions so multiple tests
could be run internally. This would have made a diff of considerable size and
frankly it is outside the scope of this fix.

The HS_DESC event was using rend_data_t from the dir connection to reply the
onion address and authentication type. With the new HSFETCH command, it's
now possible to fetch a descriptor only using the descriptor id thus
resulting in not having an onion address in any HS_DESC event.
This patch removes rend_query from the hs desc control functions and replace
it by an onion address string and an auth type.
On a successful fetch, the service id is taken from the fetched descriptor.
For that, an extra parameter is added to "store as a client" function that
contains the cache entry stored.
This will make the control event functions scale more easily over time if
other values not present in rend_data_t are needed since the rend_data from
the dir connection might not contained everything we need.

Till someone writes get_interface_address6 interface enumeration that is
routing table aware, these tests will continue to fail on certain
systems because the get_interface_address6() code is broken.
We no longer base our opinion on whether someone is a directory solely
on the routerstatus we might have for that relay, but also on a
routerinfo. Remove logic in test checking that. This broke unit tests in

Background processes spawned by Tor now will have a valid stdin.
Pluggable transports can detect this behavior with the aformentioned
enviornment variable, and exit if stdin ever gets closed.
It invokes undefined behavior, I'm afraid, since there's no other
c-legal way to test whether memwipe() works when we're not allowed to
look at it.
Closes ticket 15377.
