When we made assertions not get compiled in for the coverage case, we
missed one case where, for our tests, we really DO want to have an
assertion fail: the backtrace test.
Bugfix on 1228dd293b60a8eaab03472fa29428c5e2752c44; bug not in any
released tor
The "longest possible policy" comment in
router_parse_addr_policy_item_from_string() used an example policy
that was actually shorter than the maximum length.
This comment was amended, and expanded to count the maximum number of
characters.
Comment change only.
For this to work bt_test.py now returns an exit code indicating success or
failure. Additionally, check-local and its specific dependencies are now
obsolete so they are removed.
The zero length keys test now requires the path to the Tor binary as the first
parameter to ensure the correct Tor binary is used without hard coding a path.
The wrapper script calls the zero length keys test for each test separately to
ensure the correct shell is used (as configured by autoconf). Another solution
would have been to place the tests into separate functions so multiple tests
could be run internally. This would have made a diff of considerable size and
frankly it is outside the scope of this fix.
Unit tests for the 10 valid combinations of set/NULL config options
DirAuthorities, AlternateBridgeAuthority, AlternateDirAuthority,
and FallbackDir.
Add assertion in consider_adding_dir_servers() for checks in
validate_dir_servers():
"You cannot set both DirAuthority and Alternate*Authority."
Only add the default fallback directories when the DirAuthorities,
AlternateDirAuthority, and FallbackDir directory config options
are set to their defaults.
The default fallback directory list is currently empty, this fix will
only change tor's behaviour when it has default fallback directories.
Fixes bug 15642; bugfix on 90f6071d8d in 0.2.4.7-alpha. Patch by "teor".
When self-testing reachability, use ExtendAllowPrivateAddresses
to determine if local/private addresses imply reachability.
The previous fix used TestingTorNetwork, which implies
ExtendAllowPrivateAddresses, but this excluded rare configs where
ExtendAllowPrivateAddresses is set but TestingTorNetwork is not.

The HS_DESC_CONTENT event results in multiple line thus must be prefixed
with a "650+" and ending with "650 OK".

The HS_DESC event was using rend_data_t from the dir connection to reply the
onion address and authentication type. With the new HSFETCH command, it's
now possible to fetch a descriptor only using the descriptor id thus
resulting in not having an onion address in any HS_DESC event.
This patch removes rend_query from the hs desc control functions and replace
it by an onion address string and an auth type.
On a successful fetch, the service id is taken from the fetched descriptor.
For that, an extra parameter is added to "store as a client" function that
contains the cache entry stored.
This will make the control event functions scale more easily over time if
other values not present in rend_data_t are needed since the rend_data from
the dir connection might not contained everything we need.

Big refactor of the HS client descriptor fetch functionnality. This allows
to fetch an HS descriptor using only a descriptor ID. Furthermore, it's also
possible to provide a list of HSDir(s) now that are used instead of the
automatically choosen one.
The approach taken was to add a descriptor_id field to the rend_data_t
structure so it can be used, if available, by the HS client. The onion
address field however has priority over it that is if both are set, the
onion address is used to fetch the descriptor.
A new public function is introduced called rend_client_fetch_v2_desc(...)
that does NOT lookup the client cache before fetching and can take a list of
HSDirs as a parameter.
The HSFETCH control command now uses this new function thus making it work
and final.

As defined in section 4.1.26 in the control-spec.txt, this new event replies
the content of a successfully fetched HS descriptor. This also adds a unit
test for the controller event.

This adds the command on the controller side that parses and validate
arguments but does nothing for now. The HS desriptor fetch must be
modularized a bit more before we can use the command.
See control-spec.txt section 3.26 for more information on this command.

Incidently, this fixes a bug where the maximum value was never used when
only using crypto_rand_int(). For instance this example below in
rendservice.c never gets to INTRO_POINT_LIFETIME_MAX_SECONDS.
int intro_point_lifetime_seconds =
INTRO_POINT_LIFETIME_MIN_SECONDS +
crypto_rand_int(INTRO_POINT_LIFETIME_MAX_SECONDS -
INTRO_POINT_LIFETIME_MIN_SECONDS);

An introduction point is currently rotated when the amount of INTRODUCE2
cells reached a fixed value of 16384. This makes it pretty easy for an
attacker to inflate that number and observe when the IP rotates which leaks
the popularity of the HS (amount of client that passed through the IP).
This commit makes it a random count between the current value of 16384 and
two times that.
Fixes#15745
