Apparently, the unit tests relied on being able to make ed->x509
link certs even when they hadn't set any server flags in the
options. So instead of making "client" mean "never generate an
ed->x509 cert", we'll have it mean "it's okay not to generate an
ed->x509 cert".
(Going with a minimal fix here, since this is supposed to be a
stable version.)
The tests previously assumed that the link handshake code would be
calling get_my_certs() -- when I changed it to call get_own_cert()
instead for the (case 2) 22460 fix, the tests failed, since the tls
connection wasn't really there.
This change makes us start mocking out the tor_tls_get_own_cert()
function too.
It also corrects the behavior of the mock_get_peer_cert() function
-- it should have been returning a newly allocated copy.
It's okay to call add_ed25519_cert with a NULL argument: so,
document that. Also, add a tor_assert_nonfatal() to catch any case
where we have failed to set own_link_cert when conn_in_server_mode.
Whenever we rotate our TLS context, we change our Ed25519
Signing->Link certificate. But if we've already started a TLS
connection, then we've already sent the old X509 link certificate,
so the new Ed25519 Signing->Link certificate won't match it.
To fix this, we now store a copy of the Signing->Link certificate
when we initialize the handshake state, and send that certificate
as part of our CERTS cell.
Fixes one case of bug22460; bugfix on 0.3.0.1-alpha.
Previously we could sometimes change our signing key, but not
regenerate the certificates (signing->link and signing->auth) that
were signed with it. Also, we would regularly replace our TLS x.509
link certificate (by rotating our TLS context) but not replace our
signing->link ed25519 certificate. In both cases, the resulting
inconsistency would make other relays reject our link handshakes.
Fixes two cases of bug 22460; bugfix on 0.3.0.1-alpha.
The encrypted_data_length_is_valid() function wasn't validating correctly the
length of the encrypted data of a v3 descriptor. The side effect of this is
that an HSDir was rejecting the descriptor and ultimately not storing it.
Fixes#22447

A fair number of our mock_impl declarations were messed up so that
even our special AM_ETAGSFLAGS couldn't find them.
This should be a whitespace-only patch.
When directory authorities reject a router descriptor due to keypinning,
free the router descriptor rather than leaking the memory.
Fixes bug 22370; bugfix on 0.2.7.2-alpha.
If we add the element itself, we will later free it when we free the
descriptor, and the next time we go to look at MyFamily, things will
go badly.
Fixes the rest of bug 22368; bugfix on 0.3.1.1-alpha.
If we free them here, we will still attempt to access the freed memory
later on, and also we will double-free when we are freeing the config.
Fixes part of bug 22368.
This patch lifts the return value, rv, variable to the beginning of the
function, adds a 'done' label for clean-up and function exit and makes
the rest of the function use the rv value + goto done; instead of
cleaning up in multiple places.

We used to not set the guard state in launch_direct_bridge_descriptor_fetch().
So when a bridge descriptor fetch failed, the guard subsystem would never
learn about the fail (and hence the guard's reachability state would not
be updated).
Directory authorities now reject relays running versions
0.2.9.1-alpha through 0.2.9.4-alpha, because those relays
suffer from bug 20499 and don't keep their consensus cache
up-to-date.
Resolves ticket 20509.
parse_config_line_from_str_verbose() already looks for strings
that are surrounded by quotes, and processes them with
unescape_string(). So things were getting decoded twice, which was
(in turn) playing havoc with backslashes on Windows.
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
Before we've set our options, we can neither call get_options() nor
networkstatus_get_latest_consensus().
Fixes bug 22252; bugfix on 4d9d2553ba
in 0.2.9.3-alpha.
Replace the 177 fallbacks originally introduced in Tor 0.2.9.8 in
December 2016 (of which ~126 were still functional), with a list of
151 fallbacks (32 new, 119 existing, 58 removed) generated in May 2017.
Resolves ticket 21564.
This patch makes us use FALLBACK_COMPRESS_METHOD to try to fetch an
object from the consensus diff manager in case no mutually supported
result was found. This object, if found, is then decompressed using the
spooling system to the client.
See: https://bugs.torproject.org/21667
This patch removes the calls to spooled_resource_new() when trying to
download the consensus. All calls should now be going through the
consdiff manager.
See: https://bugs.torproject.org/21667
This patch ensures that we use the current consensus in the case where
no consensus diff was found or a consensus diff wasn't requested.
See: https://bugs.torproject.org/21667
These still won't do anything till I get the values to be filled in.
Also, I changed the API a little (with corresponding changes in
directory.c) to match things that it's easier to store.
This patch changes handle_get_current_consensus() to make it read the
current consensus document from the consensus caching subsystem.
See: https://bugs.torproject.org/21667
Failure to do this caused an assertion failure with #22246 . This
assertion failure can be triggered remotely, so we're tracking it as
medium-severity TROVE-2017-002.
Closes bug 22245; bugfix on 0.0.9rc1, when bandwidth accounting was
first introduced.
