When validating a new descriptor against our rend cache failure, we were
added the failure entry to the new cache entry without duplicating. It was
then freed just after the validation ending up in a very bad memory state
that was making tor abort(). To fix this, a dup function has been added and
used just before adding the failure entry.

Some slower configurations, like OS X i386, need 35 seconds to reliably
bootstrap larger chutney networks. Increase default bootstrap time in
src/test/test-network.h to 35 seconds.
No functional changes, but since NoKeepAliveIsolateSOCKSAuth isn't
part of isoflag, it should be checked where all other similar options
are, and bypass the (no-op) masking at the end.
Increase default boostrap time in test-network.sh to 30 seconds,
for larger networks like bridges+ipv6+hs.
This avoids the failure-hiding issues inherent in the retry approach
in #16952.
This controls the circuit dirtyness reset behavior added for Tor
Browser's user experience fix (#15482). Unlike previous iterations
of this patch, the tunable actually works, and is documented.
(These inputs are possible when Shadow starts the world at time_t 0,
and breaks our assumption that Tor didn't exist in the 1970s.)
Fixes regression introduced in 241e6b09. Fixes#16980.
make test-network-all is Makefile target which verifies a series
of test networks generated using test-network.sh and chutney.
It runs IPv6 and mixed version test networks if the prerequisites are
available.
Each test network reports PASS, FAIL, or SKIP.
Closes ticket 16953. Patch by "teor".
Also adds "--hs-multi-client 1" option to TEST_NETWORK_FLAGS.
This resolves#17012.
Larger networks, such as bridges+hs, may fail until #16952 is merged.
Performing lookups in both the client and service side descriptor
caches from the same rend_cache_lookup_entry() function increases the
risk of accidental API misuse.
I'm separating the lookup functions to keep the caches distinct.
Parameterize the rend_cache_clean() function to allow it clean
old rendezvous descriptors from the service-side cache as well as
the client descriptor cache.
Including the replica number in the HS_DESC CREATED event provides
more context to a control port client. The replica allows clients
to more easily identify each replicated descriptor from the
independantly output control events.
Entries in the service-side descriptor cache are now cleaned when
rend_cache_free_all() is called. The call to tor_free(intro_content)
in rend_cache_store_v2_desc_as_service() is moved to prevent a
potential double-free when a service has a descriptor with a newer
timestamp already in it's service-side descriptor cache.
Adds an Enum which represents the different types of rendezvous
descriptor caches. This argument is passed in each call to
rend_cache_lookup_entry() to specify lookup in the client-side or
service-side descriptor caches.
Adds a control command to fetch a local service descriptor from the
service descriptor cache. The local service descriptor cache is
referenced by the onion address of the service.
This control command is documented in the control spec.
When this is set, and Tor is running as a relay, it will not
generate or load its secret identity key. You can manage the secret
identity key with --keygen. Implements ticket 16944.
Apparently this only happens with clang (or with some particular
clang versions), and only on i386.
Fixes 16970; bug not in any released Tor.
Found by Teor; fix from Yawning.
In a nutshell, since a circuit can not exit at its entry point, it's very
easy for an attacker to find the hidden service guard if only one EntryNodes
is specified since for that guard, the HS will refuse to build a rendezvous
circuit to it.
For now, the best solution is to stop tor to allow a single EntryNodes for
an hidden service.
