The tor_cert_get_checkable_sig function uses the signing key included in
the certificate (if available) when a separate public key is not given.
When the signature is valid, the tor_cert_checksig function copies the
public key from the checkable structure to the public key field of the
certificate signing key.
In situations where the separate public key is not given but the
certificate includes a signing key, the source and destination pointers
in the copy operation are equal and invoke undefined behavior.
Undefined behaviour is avoided by ensuring both pointers are different.
The wrong list was used when looking up expired intro points in a rend
service object causing what we think could be reachability issues and
triggering a BUG log.

Without this check, we potentially look up to 3 characters before
the start of a malloc'd segment, which could provoke a crash under
certain (weird afaik) circumstances.
Fixes 17404; bugfix on 0.2.6.3-alpha.
* Don't assume that every test box has an IPv4 address
* Don't assume that every test box has a non-local address
Resolves issue #17255 released in unit tests in 0.2.7.3-rc.
Now that x509_get_not{Before,After} are functions in OpenSSL 1.1
(not yet releasesd), we need to define a variant that takes a const
pointer to X509 and returns a const pointer to ASN1_time.
Part of 17237. I'm not convinced this is an openssl bug or a tor
bug. It might be just one of those things.
Ensure that either a valid address is returned in address pointers,
or that the address data is zeroed on error.
Ensure that free_interface_address6_list handles NULL lists.
Add unit tests for get_interface_address* failure cases.
Fixes bug #17173.
Patch by fk/teor, not in any released version of tor.
... that was removed by 31eb486c46 which first appeared in
0.2.7.3-rc.
If tor is running in a ElectroBSD (or FreeBSD) jail it can't
get any IP addresses that aren't assigned to the jail by
looking at the interfaces and (by design) the
get_interface_address6_via_udp_socket_hack() fallback doesn't
work either.
The missing return code check resulted in tor_addr_is_internal()
complaining about a "non-IP address of type 49", due to reading
uninitialised memory.
Fixes#17173.
BSD make takes spaces around = literally
and produces a "TESTING_TOR_BINARY "
variable with a trailing space, which leads
to test_keygen.sh failure.
Fixes 17154
