When seccomp sandbox is active, SAVECONF failed because it was not
able to save the backup files for torrc. This commit simplifies
the implementation of SAVECONF and sandbox by making it keep only
one backup of the configuration file.
This option changes the time for which a bandwidth measurement period
must have been in progress before we include it when reporting our
observed bandwidth in our descriptors. Without this option, we only
consider a time period towards our maximum if it has been running
for a full day. Obviously, that's unacceptable for testing
networks, where we'd like to get results as soon as possible.
For non-testing networks, I've put a (somewhat arbitrary) 2-hour
minimum on the option, since there are traffic analysis concerns
with immediate reporting here.
Closes#40337.
Fun bug where we thought we were using the default "false" value when an
implicit address was detected but if we had an explicit address before, the
flag was set to true and then we would only use that value.
And thus, for some configurations, implicit addresses would be flagged as
explicit and then configuring ports goes bad.

In other words, if PublishServerDescriptor is set to 0 and AssumeReachable to
1, then allow a relay to hold a RFC1918 address.

This validation was only done if DisableNetwork was off because we would use
the global list of transports/bridges and DisableNetwork would not populate
it.
This was a problem for any user using DisableNetwork which includes Tor
Browser and thus leading to the Bug() warning.
Without a more in depth refactoring, we can't do this validation without the
global list.
The previous commit makes it that any connection to a bridge without a
transport won't happen thus we keep the security feature of not connecting to
a bridge without its corresponding transport.

When selecting the first advertised port, we always prefer the one with an

If we get an address suggestion from a directory authority and we have no
address configured or discovered, log it at notice level so the operator can
learn what address will be used by Tor.

When making sure we have a Bridge line with a ClientTransportPlugin, we
now check in the managed proxy list and so we can catch any missing
ClientTransportPlugin for a Bridge line.

The "-static" compile flag was set globally which means that all autoconf test
were attempting to be built statically and lead to failures of detecting
OpenSSL libraries and others.
This commit adds this flag only to the "tor" binary build.
There is also a fix on where to find libevent.a since it is using libtool, it
is in .libs/.
At this commit, there are still warnings being emitted that informs the user
that the built binary must still be linked dynamically with glibc.

Commit c3a0f75796 added this feature for ORPort
that we ignore any port that is not the family of our default address when
parsing the port. So if port_parse_config() was called with an IPv4 default
address, all IPv6 address would be ignored.
That makes sense for ORPort since we call twice port_parse_config() for
0.0.0.0 and [::] but for the rest of the ports, it is not good since a
perfectly valid configuration can be:
SocksPort 9050
SocksPort [::1]:9050
Any non-ORPort only binds by default to an IPv4 except the ORPort that binds
to both IPv4 and IPv6 by default.
The fix here is to always parse all ports within port_parse_config() and then,
specifically for ORPort, remove the duplicates or superseding ones. The
warning is only emitted when a port supersedes another.
A unit tests is added to make sure SocksPort of different family always exists
together.

Typos found with codespell.
Please keep in mind that this should have impact on actual code
and must be carefully evaluated:
src/core/or/lttng_circuit.inc
- ctf_enum_value("CONTROLER", CIRCUIT_PURPOSE_CONTROLLER)
+ ctf_enum_value("CONTROLLER", CIRCUIT_PURPOSE_CONTROLLER)
At this commit, a new service registers to the module and a store is created.
It also remove itself from the metrics module if it goes away.
In order to hook into the metrics subsystem, this commit attaches the HS
subsystem into the subsystem global list so its get_metrics() call can be
accessible.
HS initialization is still _not_ done through the subsys module as it is
likely require much more testing.

Tor has a feature to preserve unrecognized state file entries in
order to maintain forward compatibility. But this feature, along
with some unused code that we never actually removed, led to us
keeping items that were of no use to the user, other than at worst
to preserve ancient information about them.
This commit adds a feature to remove obsolete entries when we load
the file.
Closes ticket 40137.
This patch moves the logic for handling outbound addresses in torrc to
before we handle pluggable transports. Since we need access to the
values in OutboundBindAddress and friends for #5304 we have to parse
these values before we spawn any PT's.
This commit is code movement only.
See: https://bugs.torproject.org/5304
This patch renames the enumeration value in `outbound_addr_t` from
`OUTBOUND_ADDR_EXIT_AND_OR` to `OUTBOUND_ADDR_ANY` since with the
arrival of `OUTBOUND_ADDR_PT` it no longer makes sense to call the
fallback value for "Exit and OR". Instead we rename it to "any".
See: https://bugs.torproject.org/5304
This patch adds a new option to torrc: `OutboundBindAddressPT`. This
option works in the same way as `OutboundBindAddressOR` and
`OutboundBindAddressExit` in that it allows the user to specify which
outbound IP address the user wants the PT to make its connections from.
There is one difference though in that OutboundBindAddressPT will only
be a suggestion for the PT to use since Tor cannot enforce whether or
not the PT actually uses this option for anything.
