Return early when there is no suitable IPv6 ORPort.
Show the address and port on error, using a convenience function.
Code simplification and refactoring.
Cleanup after 32588.
When IPv6 ORPorts are set to "auto", tor relays and bridges would
advertise an incorrect port in their descriptor.
This may be a low-severity memory safety issue, because the published
port number may be derived from uninitialised or out-of-bounds memory
reads.
Fixes bug 32588; bugfix on 0.2.3.9-alpha.
Previously we just ignored this option, which would leave it unset,
and cause an assertion failure later on when running with the User
option.
Fixes bug 33668; bugfix on 0.4.3.1-alpha.
Copy required DLLs to test and app, before running tor's tests.
This ensures that tor.exe and test*.exe use the correct version of each
DLL. This fix is not required, but we hope it will avoid DLL search
issues in future.
Closes bug 33673; bugfix on 0.3.4.2-alpha.
For example, "TOR_SKIP_TESTCASES=crypto/.. ./src/test/test" will run
the tests and suppress all the "crypto/" tests. You could get the
same effect by running "./src/test/test :crypto/..", but that can be
harder to arrange from CI.
Part of a fix/workaround for 33643.
Given that ed25519 public key validity checks are usually not needed
and (so far) they are only necessary for onion addesses in the Tor
protocol, we decided to fix this specific bug instance without
modifying the rest of the codebase (see below for other fix
approaches).
In our minimal fix we check that the pubkey in
hs_service_add_ephemeral() is valid and error out otherwise.
In the openssl that I have, it should be safe to only check the size
of n. But if I'm wrong, or if other openssls work differently, we
should check whether any of the fields are too large.
Issue spotted by Teor.
This function does a nonfatal assertion to make sure that a machine
is not registered twice, but Tobias Pulls found a case where it
happens. Instead, make the function exit early so that it doesn't
cause a remotely triggered memory leak.
Fixes bug 33619; bugfix on 0.4.0.1-alpha. This is also tracked as
TROVE-2020-004.
