Removes a check to PublishHidServDescriptors in
rend_consider_services_upload(). This allows descriptors to be
generated and stored in the local cache when PublishHidServDescriptor = 0.
Keep the PublishHidServDescriptors option check in
rend_consider_descriptor_republication(). We will never need to republish
a descriptor if we are not publishing descriptors to the HSDirs.
Service descriptors are now generated regardless of the the
PublishHidServDescriptors option. The generated descriptors are stored
in the service descriptor cache.
The PublishHidServDescriptors = 1 option now prevents descriptor
publication to the HSDirs rather than descriptor generation.
Deindent a block of code inside the PublishHidServDescriptors option
check in upload_service_descriptor(). Stylistic commit to make the
subsequent reworking of this code cleaner.
The HS_DESC CREATED event should be emmited when a new service descriptor

Adds a service descriptor cache which is indexed by service ID. This
descriptor cache is used to store service descriptors generated by a
local rendevous service.
The service-side cach can be queried by calling rend_cache_lookup_entry()
with the 'service' argument set to 1.
We don't want to accept any work after one of our worker functions has
returned WQ_RPL_SHUTDOWN. This testcase currently fails, because we do
not actually stop any of the worker threads.
We used to use this when we had some controllers that would accept
long names and some that wouldn't. But it's been obsolete for a
while, and it's time to strip it out of the code.
Previously we'd put these strings right on the controllers'
outbufs. But this could cause some trouble, for these reasons:
1) Calling the network stack directly here would make a huge portion
of our networking code (from which so much of the rest of Tor is
reachable) reachable from everything that potentially generated
controller events.
2) Since _some_ events (EVENT_ERR for instance) would cause us to
call connection_flush(), every control_event_* function would
appear to be able to reach even _more_ of the network stack in
our cllgraph.
3) Every time we generated an event, we'd have to walk the whole
connection list, which isn't exactly fast.
This is an attempt to break down the "blob" described in
http://archives.seul.org/tor/dev/Mar-2015/msg00197.html -- the set of
functions from which nearly all the other functions in Tor are
reachable.

If an OP were to send a CREATE_FAST cell to an OR, and that
CREATE_FAST cell had unparseable key material, then tor_free() would
be called on the create cell twice. This fix removes the second
(conditional on the key material being bad) call to tor_free(), so
that now the create cell is always freed once, regardless of the status of
the key material.
(This isn't actually a double-free bug, since tor_free() sets its
input to NULL, and has no effect when called with input NULL.)
Instead of having it call update_all_descriptor_downloads and
update_networkstatus_downloads directly, we can have it cause them to
get rescheduled and called from run_scheduled_events.

The base64 and base32 functions used to be in crypto.c;

This patch makes a {crypto,util}_format.[ch], and puts more functions

The control port was using set_max_file_descriptors() with a limit set to 0
to query the number of maximum socket Tor can use. With the recent changes
to that function, a check was introduced to make sure a user can not set a
value below the amount we reserved for non socket.
This commit adds get_max_sockets() that returns the value of max_sockets so
we can stop using that "setter" function to get the current value.
Finally, the dead code is removed that is the code that checked for limit
equal to 0. From now on, set_max_file_descriptors() should never be used
with a limit set to 0 for a valid use case.

When cleaning up extra circuits that we've opened for performance reason, we
need to count all the introduction circuit and not only the established ones
else we can end up with too many introduction points.

To upload a HS descriptor, this commits makes it that we wait for all
introduction point to be fully established.
Else, the HS ends up uploading a descriptor that may contain intro points
that are not yet "valid" meaning not yet established or proven to work. It
could also trigger three uploads for the *same* descriptor if every intro
points takes more than 30 seconds to establish because of desc_is_dirty
being set at each intro established.
To achieve that, n_intro_points_established varialbe is added to the
rend_service_t object that is incremented when we established introduction
point and decremented when we remove a valid intro point from our list.
The condition to upload a descriptor also changes to test if all intro
points are ready by making sure we have equal or more wanted intro points
that are ready.
The desc_id_dirty flag is kept to be able to still use the
RendInitialPostPeriod option.

There is a case where if the introduction circuit fails but the node is
still in the consensus, we clean up the intro point and choose an other one.
This commit fixes that by trying to reuse the existing intro point with a
maximum value of retry.
A retry_nodes list is added to rend_services_introduce() and when we remove
an invalid intro points that fits the use case mentionned before, we add the
node to the retry list instead of removing it. Then, we retry on them before
creating new ones.
This means that the requirement to remove an intro point changes from "if no
intro circuit" to "if no intro circuit then if no node OR we've reached our
maximum circuit creation count".
For now, the maximum retries is set to 3 which it completely arbitrary. It
should also at some point be tied to the work done on detecting if our
network is down or not.
Fixes#8239
Signed-off-by: David Goulet <dgoulet@ev0ke.net>
The reasoning for refactoring this function is that removing the
introduction point adaptative algorithm (#4862) ended up changing quite a
bit rend_services_introduce(). Also, to fix some open issues (#8239, #8864
and #13483), this work had to be done.
First, this removes time_expiring variable in an intro point object and
INTRO_POINT_EXPIRATION_GRACE_PERIOD trickery and use an expiring_nodes list
where intro nodes that should expire are moved to that list and cleaned up
only once the new descriptor is successfully uploaded. The previous scheme
was adding complexity and arbitrary timing to when we expire an intro point.
We keep the intro points until we are sure that the new descriptor is
uploaded and thus ready to be used by clients. For this,
rend_service_desc_has_uploaded() is added to notify the HS subsystem that
the descriptor has been successfully uploaded. The purpose of this function
is to cleanup the expiring nodes and circuits if any.
Secondly, this adds the remove_invalid_intro_points() function in order to
split up rend_services_introduce() a bit with an extra modification to it
that fixes#8864. We do NOT close the circuit nor delete the intro point if
the circuit is still alive but the node was removed from the consensus. Due
to possible information leak, we let the circuit and intro point object
expire instead.
Finally, the whole code flow is simplified and large amount of documentation
has been added to mostly explain the why of things in there.

The runtime sanity checking is slightly different from the optimized
basepoint stuff in that it uses a given implementation's self tests if
available, and checks if signing/verification works with a test vector
from the IETF EdDSA draft.
The unit tests include a new testcase that will fuzz donna against ref0,
including the blinding and curve25519 key conversion routines. If this
is something that should be done at runtime (No?), the code can be
stolen from there.
Note: Integrating batch verification is not done yet.
Integration work scavanged from nickm's `ticket8897_9663_v2` branch,
with minor modifications. Tor will still sanity check the output but
now also attempts to catch extreme breakage by spot checking the
optimized implementation vs known values from the NaCl documentation.
Implements feature 9663.
This needs to be done to allow for the possibility of removing the
ref10 code at a later date, though it is not performance critical.
When integrated by kludging it into tor, it passes unit tests, and is
twice as fast.
Integrating it the "wrong" way into common/crypto_ed25519.c passes
`make check`, and there appear to be some known answer tests for this,
so I assume I got it right.
Blinding a public key goes from 139.10 usec to 70.78 usec using
ed25519-donna (NB: Turboboost/phase of moon), though the code isn't
critical path, so supporting it is mostly done for completeness.
Integrate ed25519-donna into the build process, and provide an
interface that matches the `ref10` code. Apart from the blinding and
Curve25519 key conversion, this functions as a drop-in replacement for
ref10 (verified by modifying crypto_ed25519.c).
Tests pass, and the benchmarks claim it is quite a bit faster, however
actually using the code requires additional integration work.
The following arguments change how chutney verifies the network:
--bytes n sends n bytes per test connection (10 KBytes)
--connections n makes n test connections per client (1)
--hs-multi-client 1 makes each client connect to each HS (0)
Requires the corresponding chutney performance testing changes.
Note: using --connections 7 or greater on a HS will trigger #15937.

This is a way to specify the amount of introduction points an hidden service

Fixes#4862
Signed-off-by: David Goulet <dgoulet@ev0ke.net>
When we ran out of intro points for a hidden service (which could
happen on a newnym), we would change the connection's state back to
"waiting for hidden service descriptor." But this would make an
assertion fail if we went on to call circuit_get_open_circ_or_launch
again.
This fixes bug 16013; I believe the bug was introduced in
38be533c69, where we made it possible for
circuit_get_open_circ_or_launch() to change the connection's state.
RFC 952 is approximately 30 years old, and people are failing to comply,
by serving A records with '_' as part of the hostname. Since relaxing
the check is a QOL improvement for our userbase, relax the check to
allow such abominations as destinations, especially since there are
likely to be other similarly misconfigured domains out there.
When I fixed#11243, I made it so we would take the digest of a
descriptor before tokenizing it, so we could desist from download
attempts if parsing failed. But when I did that, I didn't remove an
assertion that the descriptor began with "onion-key". Usually, this
was enforced by "find_start_of_next_microdescriptor", but when
find_start_of_next_microdescriptor returned NULL, the assertion was
triggered.

This is a new collator type that follows proposal 220 for deciding
which identities to include. The rule is (approximately):
If a <ed,rsa> identity is listed by more than half of authorities,
include it. And include all <rsa> votes about that node as
matching.
Otherwise, if an <*,rsa> or <rsa> identity is listed by more than
half of the authorities, and no <ed,rsa> has been listed, include
it.
* Include ed25519 identities in votes
* Include "no ed25519 identity" in votes
* Include some commented-out code about identity voting. (This
will disappear.)
* Include some functions for identity voting (These will disappear.)
* Enforce uniqueness in ed25519 keys within a vote
Extrainfo documents are now ed-signed just as are router
descriptors, according to proposal 220. This patch also includes
some more tests for successful/failing parsing, and fixes a crash
bug in ed25519 descriptor parsing.
An earlier version of these tests was broken; now they're a nicer,
more robust, more black-box set of tests. The key is to have each
test check a handshake message that is wrong in _one_ way.
This includes the link handshake variations for proposal220.
We'll use this for testing first, and then use it to extend our
current code to support prop220.
When there are annotations on a router descriptor, the
ed25519-identity element won't be at position 0 or 1; it will be at
router+1 or router-1.
This patch also adds a missing smartlist function to search a list for
an item with a particular pointer.
With this patch:
* Authorities load the key-pinning log at startup.
* Authorities open a key-pinning log for writing at startup.
* Authorities reject any router with an ed25519 key where they have
previously seen that ed25519 key with a different RSA key, or vice
versa.
* Authorities warn about, but *do not* reject, RSA-only descriptors
when the RSA key has previously gone along with an Ed25519 key.
(We should make this a 'reject' too, but we can't do that until we're
sure there's no legit reason to downgrade to 0.2.5.)
This module implements a key-pinning mechanism to ensure that it's
safe to use RSA keys as identitifers even as we migrate to Ed25519
keys. It remembers, for every Ed25519 key we've seen, what the
associated Ed25519 key is. This way, if we see a different Ed25519
key with that RSA key, we'll know that there's a mismatch.
We persist these entries to disk using a simple format, where each
line has a base64-encoded RSA SHA1 hash, then a base64-endoded
Ed25519 key. Empty lines, misformed lines, and lines beginning with
a # are ignored. Lines beginning with @ are reserved for future
extensions.
Routers now use TAP and ntor onion keys to sign their identity keys,
and put these signatures in their descriptors. That allows other
parties to be confident that the onion keys are indeed controlled by
the router that generated the descriptor.

For prop220, we have a new ed25519 certificate type. This patch

keys. (Some parts of master identity key encryption are done, but
the implementation of that isn't finished)
If the OpenSSL team accepts my patch to add an
SSL_get_client_ciphers function, this patch will make Tor use it
when available, thereby working better with openssl 1.1.
We previously used this function instead of SSL_set_cipher_list() to
set up a stack of client SSL_CIPHERs for these reasons:
A) In order to force a particular order of the results.
B) In order to be able to include dummy entries for ciphers that
this build of openssl did not support, so we could impersonate
Firefox harder.
But we no longer do B, since we merged proposal 198 and stopped
lying about what ciphers we know.
And A was actually pointless, since I had misread the implementation
of SSL_set_cipher_list(). It _does_ do some internal sorting, but
that is pre-sorting on the master list of ciphers, not sorting on
the user's preferred order.
As OpenSSL >= 1.0.0 is now required, ECDHE is now mandatory. The group
has to be validated at runtime, because of RedHat lawyers (P224 support
is entirely missing in the OpenSSL RPM, but P256 is present and is the
default).
Resolves ticket #16140.
The key here is to never touch ssl->cipher_list directly, but only
via SSL_get_ciphers(). But it's not so simple.
See, if there is no specialized cipher_list on the SSL object,
SSL_get_ciphers returns the cipher_list on the SSL_CTX. But we sure
don't want to modify that one! So we need to use
SSL_set_cipher_list first to make sure that we really have a cipher
list on the SSL object.
When set, this limits the maximum number of simultaneous streams per
rendezvous circuit on the server side of a HS, with further RELAY_BEGIN
cells being silently ignored.
This can be modified via "HiddenServiceMaxStreamsCloseCircuit", which
if set will cause offending rendezvous circuits to be torn down instead.

Ephemeral services will be listed in rend_services_list at the end of

order to have a single place where we initialize that data structure.
Furthermore, an array of descriptor IDs is added (one per replica) so we can
keep a copy of the current id in the object. It will be used to purge the
last hid serv request cache using those descriptor IDs. When they change,
they will be replaced and the old ones will be purged from the cache.

Fixes#15850, part of #15801. Change file is added by this commit. The
original comment in the reverted commit is removed because right now we
*need* a DirPort until #15849 is implemented so no doubt nor confusion there
anymore.
This reverts commit 80bed1ac96.
