Parse the value to UseEntryNodes_option, then set UseEntryNodes before
validating options.
This way, Authorities, Tor2web, and Single Onion Services don't write
spurious "UseEntryNodes 0" lines to their configs. Document the fact that
these tor configurations ignore UseEntryNodes in the manual page.
Also reorder options validation so we modify UseEntryNodes first, then
check its value against EntryNodes.
And silence a warning about disabled UseEntryNodes for hidden services
when we're actually in non-anonymous single onion service mode.
The changes in #19973 fixed ReachableAddresses being applied
too broadly, but they also broke Tor2web (somewhat unintentional)
compatibility with ReachableAddresses.
This patch restores that functionality, which makes intro and
rend point selection is consistent between Tor2web and Single Onion
Services.
Add experimental OnionServiceSingleHopMode and
OnionServiceNonAnonymousMode options. When both are set to 1, every
hidden service on a tor instance becomes a non-anonymous Single Onion
Service. Single Onions make one-hop (direct) connections to their
introduction and renzedvous points. One-hop circuits make Single Onion
servers easily locatable, but clients remain location-anonymous.
This is compatible with the existing hidden service implementation, and
works on the current tor network without any changes to older relays or
clients.

Redesign single onion service poisoning.
When in OnionServiceSingleHopMode, each hidden service key is poisoned
(marked as non-anonymous) on creation by creating a poison file in the
hidden service directory.
Existing keys are considered non-anonymous if this file exists, and
anonymous if it does not.
Tor refuses to launch in OnionServiceSingleHopMode if any existing keys
are anonymous. Similarly, it refuses to launch in anonymous client mode
if any existing keys are non-anonymous.
Rewrite the unit tests to match and be more comprehensive.
Adds a bonus unit test for rend_service_load_all_keys().
(We check consensus method when deciding whether to assume a node is
valid. No need to check the consensus method for Running, since
we will never see a method before 13.)

Fixes bug 20117; bugfix on 02c320916e in tor-0.2.4.10-alpha.
Reported by Jesse V.
Users can't run an anonymous client and non-anonymous single
onion service at the same time. We need to know whether we have
any client ports or sockets open to do this check.
When determining whether a client port (SOCKS, Trans, NATD, DNS)
is set, count unix sockets when counting client listeners. This
has no user-visible behaviour change, because these options are
set once and never read in the current tor codebase.
Don't count sockets when setting ControlPort_set, that's what
ControlSocket is for. (This will be reviewed in #19665.)
Don't count sockets when counting server listeners, because the code
that uses these options expects to count externally-visible ports.
(And it would change the behaviour of Tor.)
Copying the integer 42 in a char buffer has a different representation
depending on the endianess of the system thus that unit test was failing on
big endian system.
This commit introduces a python script, like the one we have for SRV, that
computes a COMMIT/REVEAL from scratch so we can use it as a test vector for
our encoding unit tests.
With this, we use a random value of bytes instead of a number fixing the
endianess issue and making the whole test case more solid with an external
tool that builds the COMMIT and REVEAL according to the spec.

Rely on onion_populate_cpath to check that we're only using
TAP for the rare hidden service cases.

This bug had existed since 0.2.4.7-alpha, but now that we have
FallbackDirs by default, it actually matters.
Fixes bug 19947; bugfix on 0.2.4.7-alpha or maybe 0.2.8.1-alpha.
Rubiate wrote the patch; teor wrote the changes file.
OpenBSD removes this function, and now that Tor requires Libevent 2,
we should also support the OpenBSD Libevent 2.

If we know a node's version, and it can't do ntor, consider it not running.
If we have a node's descriptor, and it doesn't have a valid ntor key,
consider it not running.
Refactor these checks so they're consistent between authorities and clients.
Before, they checked for version 0.2.4.18-rc or later, but this
would not catch relays without version lines, or buggy or malicious
relays missing an ntor key.
If we did not find a non-private IPaddress by iterating over interfaces,
we would try to get one via
get_interface_address6_via_udp_socket_hack(). This opens a datagram
socket with IPPROTO_UDP. Previously all our datagram sockets (via
libevent) used IPPROTO_IP, so we did not have that in the sandboxing
whitelist. Add (SOCK_DGRAM, IPPROTO_UDP) sockets to the sandboxing
whitelist. Fixes bug 19660.
The test-network-all target assumes the test-driver script lives in the
current working directory. This assumption breaks out-of-tree builds
because it actually lives in the source directory.
Automake 1.12 introduces `LOG_DRIVER` which defines the location of the
test driver script. Because Tor still supports Automake 1.11 we use the
default value of this variable directly. The default value uses the
configured shell for calling the test driver script and explicitly
prefixes the source directory.
This fixes#19608, allowing IPv6-only clients to use
microdescriptors, while preserving the ability of bridge clients
to have some IPv4 bridges and some IPv6 bridges.
Fix on c281c036 in 0.2.8.2-alpha.
We introduded a shadowed variable, thereby causing a log message to
be wrong. Fixes 19578. I believe the bug was introduced by
54d7d31cba in 0.2.2.29-beta.
asciidoc adds a timestamp at the end of a generated HTML file.
This timestamp is based on the date of the file but it can change
depending on the TZ environment variable.
Our sandboxing code would not allow us to write to stats/hidserv-stats,
causing tor to abort while trying to write stats. This was previously
masked by bug#19556.
When sandboxing is enabled, we could not write any stats to disk.
check_or_create_data_subdir("stats"), which prepares the private stats
directory, calls check_private_dir(), which also opens and not just stats() the
directory. Therefore, we need to also allow open() for the stats dir in our
sandboxing setup.
From 0.2.7.2-alpha onwards, Exits would reject all the IP addresses
they knew about in their exit policy. But this may have disclosed
addresses that were otherwise unlisted.
Now, only advertised addresses are rejected by default by
ExitPolicyRejectPrivate. All known addresses are only rejected when
ExitPolicyRejectLocalInterfaces is explicitly set to 1.
If we manually remove fallbacks in C by adding '/*' and '*/' on separate
lines, stem still parses them as being present, because it only looks at
the start of a line.
Add a comment to this effect in the generated source code.
zlib 1.2 came out in 2003; earlier versions should be dead by now.
Our workaround code was only preventing us from using the gzip
encoding (if we decide to do so), and having some dead code linger
around in torgzip.c
The Autoconf macro AC_USE_SYSTEM_EXTENSIONS defines preprocessor macros
which turn on extensions to C and POSIX. The macro also makes it easier
for developers to use the extensions without needing (or forgetting) to
define them manually.
The macro can be safely used because it was introduced in Autoconf 2.60
and Tor requires Autoconf 2.63 and above.
When deleting an ephemeral HS, we were only iterating on circuit with an
OPEN state. However, it could be possible that an intro point circuit didn't
reached the open state yet.
This commit makes it that we close the circuit regardless of its state
except if it was already marked for close.
