This adds a couple of configure commands to control whether we're
requiring all dependencies to be available locally (default) or not
(--enable-cargo-online-mode). When building from a tarball, we require
the RUST_DEPENDENCIES variable to point to the local repository of
crates. This also adds src/ext/rust as a git submodule that contains
such a local repository for easy setup.
Passing --enable-cargo-online-mode during configure allows cargo to make
network requests while building Tor or running tests. If this flag is
not supplied, the dependencies need to be available in the form of a
local mirror.
This gives an indication in the log that Tor was built with Rust
support, as well as laying some groundwork for further string-returning
APIs to be converted to Rust
config_get_lines is now split into two functions:
- config_get_lines which is the same as before we had %include
- config_get_lines_include which actually processes %include
Cleanup logic in test_intro_point_registration() invoked tt_assert()
in a way that could cause it to jump backward into the cleanup code if
the assertion failed, causing Coverity to see a double free (CID
1397192). Move the tt_assert() calls into a helper function having
the well-defined task of testing hs_circuitmap_free_all().
Fixes#22231.
A descriptor only contains the curve25519 public key in the enc-key field so
the private key should not be in that data structure. The service data
structures will have access to the full keypair (#20657).
Furthermore, ticket #21871 has highlighted an issue in the proposal 224 about
the encryption key and legacy key being mutually exclusive. This is very wrong
and this commit fixes the code to follow the change to the proposal of that
ticket.

A for-loop in test_channelpadding_timers() would never run because it
was trying to increment a counter up to CHANNELS_TO_TEST/3 after an
earlier block already incremented it to CHANNELS_TO_TEST/2.
Fixes#22221, CID 1405983.

The descriptor fields can't be validated properly during encoding because they
are signed by a descriptor signing key that we don't have in the unit test.
Removing the test case for now but ultimately we need an independent
implementation that can encode descriptor and test our decoding functions with
that.

Create the hs_test_helpers.{c|h} files that contains helper functions to
create introduction point, descriptor and compare descriptor.
Used by both the hs cache and hs descriptor tests. Unify them to avoid code
duplication.
Also, this commit fixes the usage of the signing key that was wrongly used
when creating a cross signed certificate.

This change prevents a no-longer-supported behavior where we change
options that would later be written back to torrc with a SAVECONF.
Also, use the "Pointer to final pointer" trick to build the
normalized list, to avoid special-casing the first element.
asan was finding an alignment issue with a cast, so set the field in the
trunnel struct and then encode it instead. Also, enable log capture and
verification.
Checking all of these parameter lists for every single connection every second
seems like it could be an expensive waste.
Updating globally cached versions when there is a new consensus will still
allow us to apply consensus parameter updates to all existing connections
immediately.
IMO, these tests should be calling options_init() to properly set everything
to default values, but when that is done, about a dozen tests fail. Setting
the one default value that broke the tests for my branch. Sorry for being
lame.
This unifies CircuitIdleTimeout and PredictedCircsRelevanceTime into a single
option, and randomizes it.
It also gives us control over the default value as well as relay-to-relay
connection lifespan through the consensus.

This defense will cause Cisco, Juniper, Fortinet, and other routers operating
in the default configuration to collapse netflow records that would normally
be split due to the 15 second flow idle timeout.
Collapsing these records should greatly reduce the utility of default netflow
data for correlation attacks, since all client-side records should become 30
minute chunks of total bytes sent/received, rather than creating multiple
separate records for every webpage load/ssh command interaction/XMPP chat/whatever
else happens to be inactive for more than 15 seconds.
The defense adds consensus parameters to govern the range of timeout values
for sending padding packets, as well as for keeping connections open.
The defense only sends padding when connections are otherwise inactive, and it
does not pad connections used solely for directory traffic at all. By default
it also doesn't pad inter-relay connections.
Statistics on the total padding in the last 24 hours are exported to the
extra-info descriptors.
