Use bridges+hs-v23 for "make test-network",
rather than using chutney's old default.
This change requires a recent version of chutney,
because the old bridges+hs-v23 did not work.
(See chutney's 33302 for details.)
Closes 28208.
The IPv6 test only runs if IPv6 is available.
Also, explicitly use the bridges+hs-v2 network for the IPv4-only test.
This network was chutney's default as of January 2020.
Closes 33300.
Add test-network-ipv4 and test-network-ipv6 tests to the Makefile.
These tests run the IPv4-only and dual-stack chutney flavours from
test-network-all.
Closes ticket 33280.
Closing these file descriptors can hide sanitiser logs.
Instead, flush the logs before tor exits, using fsync().
Some Windows environments don't have fsync(), so we check
for it at compile time.
Fixes bug 33087; bugfix on 0.4.1.6.
Stop executing the checked-out pre-commit hook from the pre-push hook.
Instead, execute the copy in the user's git dir.
Fixes bug 33284; bugfix on 0.4.1.1-alpha.
This patch ensures that we always lowercase the BridgeDistribution from
torrc in descriptors before submitting it.

Between 042 and 043, the dirauth options were modularized so this merge commit
address this by moving the AuthDirRejectUncompressedRequests to the module
along with a series of accessors.

Authorities were never sending back 503 error code because by design they
should be able to always answer directory requests regardless of bandwidth
capacity.
However, that recently backfired because of a large number of requests from
unknown source using the DirPort that are _not_ getting their 503 code which
overloaded the DirPort leading to the authority to be unable to answer to its
fellow authorities.
This is not a complete solution to the problem but it will help ease off the
load on the authority side by sending back 503 codes *unless* the connection
is from a known relay or an authority.

The "once" flag makes tor_bug_occurred_() say that future instances
of the warning will be suppressed -- but that's not something that
BUG() does. Fixes bug 33095; bugfix on 0.4.1.1-alpha.
When we added the ACTIVE and DORMANT virtual signals, we taught the
signal command to handle them, but we didn't teach SIGNAL event to
report them.
To solve this problem and prevent it from recurring, this patch
revises the implementation of control_event_signal() to use the same
signal_table that handle_control_signal() uses. This way, the two
controller commands can't become out of sync.
Fixes bug 33104; bugfix on 0.4.0.1-alpha.
Fixes bug 32673; bugfix on 0.3.0.4-alpha. We introduced these
checks in ee5471f9aa to help diagnose 21369, but we used "-1"
when "TOR_TLS_ERROR_MISC" would have been correct. Found by opara.
I don't think that this is actually getting triggered in the wild,
but if it were, it could cause nasty behavior: spurious
WANTREAD/WANTWRITE returns have a way of turning into CPU-eating
busy-loops.
We introduced these BUG() checks in b0ddaac074 to prevent a
recurrence of bug 23690. But there's a report of the BUG() message
getting triggered and filling up the disk. Let's change it to
IF_BUG_ONCE().

Stop allowing failures on the Travis CI stem tests job. It looks like

Make Tor clients tell dual-stack exits that they prefer IPv6
connections.
This change is equivalent to setting the PreferIPv6 flag on
SOCKSPorts (and most other listener ports). Tor Browser has
been setting this flag for some time, and we want to remove a
client distinguisher at exits.
Also update the man page, putting all the IP flags in their
non-default forms.
Closes ticket 32637.
* ticket 32695 removed networkstatus_consensus_has_ipv6(),
keep that change in master.
* ticket 20218 modifies the function name and comment for
routerstatus_has_visibly_changed(), keep that change
in ticket20218_rebased_squashed.
We already check if there are invalid values in
check_bridge_distribution_setting() and reject the value if that is the
case. We can therefore only have strings of [A-Z] | [a-z] | [0-9] | '-'
| '_' here which is according to the directory specification.

We hit this assertion with bug 32868, but I'm stymied figuring out
how we wound up with a routerstatus like this. This patch is a
diagnostic to attempt to figure out what is going on, and to avoid a
crash in the meantime.
When practracker is disabled, its output will be empty. We don't
want that happening during our tests.

When we updated main.c to use the same entry points as tor_api.h, we
didn't update ntmain.c. This led to bugs as the two got out of
sync.
There are two calls that we drop in this patch: first, I drop the
call to set_main_thread(), since that's redundant with the init
function in compat_winthreads.c (but see #32884). Second, I drop
the check for CMD_RUN_TOR: I'll add that back with a subsequent
commit.
Closes ticket 32883.
Allow calls to dup() which was introduced in commit a22fbab986.
From a security perspective, I don't think this should impact the
security of the sandbox significantly. As far as I can tell, there
is nothing an adversary can do with a duplicated FD that can't be
done with the original.
We stopped looking at this option in 85cf6dcba3, back when we
implemented the minimal pieces of prop275. Since then, we've had
code to validate and adjust this option, and to give it a different
value in testing networks, but the option hasn't actually done
anything.
We can safely mark it as OBSOLETE, since doing so does not make any
old configuration get rejected.
Closes ticket 32807.
With v3, the "pending_final_cpath" of a circuit is always NULL which means
that for v3, established client rendezvous circuit waiting for the intro point
to ACK, will always end up timing out quickly.
This can increase the delays to which you connect to a service since in order
to succeed, the rendezvous circuit needs to fully established
(CIRCUIT_PURPOSE_C_REND_JOINED) within the cutoff of the introduction circuit
as well which is these days around 2-3 seconds.

Python 2 will be end-of-life as of 1 Jan 2020, so we can finally

In #26913 we solved a bug where CacheDirectoryGroupReadable would
override DataDirectoryGroupReadable when the two directories are the
same. We never did the same for KeyDirectory, though, because
that's a rare setting.
Now that I'm testing this code, though, fixing this issue seems
fine. Fixes bug #27992; bugfix on 0.3.3.1-alpha.
When we added the $FILTER for Windows newlines, we made

Fixes bug 32468; bugfix on 0.4.2.1-alpha.
When a SOCKS5 client sends a RESOLVE_PTR request, it must include
either an IPv4 or IPv6 address. In the past this was required to be a
binary address (address types 1 or 4), but since the refactoring of
SOCKS5 support in Tor 0.3.5.1-alpha, strings (address type 3) are also
allowed if they represent an IPv4 or IPv6 literal.
However, when a binary IPv6 address is provided,
parse_socks5_client_request converts it into a string enclosed in
brackets. This doesn't match what string_is_valid_ipv6_address
expects, so this would fail with the error "socks5 received
RESOLVE_PTR command with hostname type. Rejecting."
By replacing string_is_valid_ipv4_address/string_is_valid_ipv6_address
with tor_addr_parse, we accept strings both with and without brackets.
This fixes the handling of binary addresses, and also improves
symmetry with CONNECT and RESOLVE requests.

Obviously correct changes to already reviewed code.
Up till now, we have warned about all missing documentation, which
meant that we could never make doxygen warnings fatal. This has led
to our doxygen output getting full of errors several times in the
past.
This commit changes our approach to doxygen warnings: missing
documentation warnings are only on when the user asks for them with
--enable-missing-doc-warnings. When that option is not present,
doxygen respects the --enable-fatal-warnings flag.
Closes ticket 32385.
The current pkg-config setup has no sense of whether it is cross-compiling,
so it will detect things on the build system that are not present or are
wrong for the host system. This forces the cross-compiling build to only
look for pkg-config .pc files in --prefix.
A version of this has been the setup for many years with the Android builds.
