These functions must really never fail; so have crypto_rand() assert
that it's working okay, and have crypto_seed_rng() demand that
callers check its return value. Also have crypto_seed_rng() check
RAND_status() before returning.
Stop ignoring ExitPolicyRejectPrivate in getinfo
exit-policy/reject-private. Fix a memory leak.
Set ExitPolicyRejectPrivate in the unit tests, and make a mock
function declaration static.
Fix unit tests for get_interface_address6_list to assume less
about the interface addresses on the system.
Instead, mock get_interface_address6_list and use the mocked
function to provide a range of address combinations.
This migrates away from SHA1, and provides further hash flooding
protection on top of the randomised siphash implementation.
Add unit tests to make sure that different inputs don't have the
same hash.
exit-policy/reject-private lists the reject rules added by
ExitPolicyRejectPrivate. This makes it easier for stem to
display exit policies.
Add unit tests for getinfo exit-policy/*.
Completes ticket #17183. Patch by "teor".
Modify policies_parse_exit_policy_reject_private so it also blocks
the addresses configured for OutboundBindAddressIPv4_ and
OutboundBindAddressIPv6_, and any publicly routable port addresses
on exit relays.
Add and update unit tests for these functions.
In my testing, an IPv6-only FreeBSD jail without ::1 returned EINVAL
from tor_ersatz_socketpair. Let's not fail the unit test because of
this - it would only ever use tor_socketpair() anyway.
(But it won't work on some systems without IPv4/IPv6 localhost
(some BSD jails) by design, to avoid creating sockets on routable
IP addresses. However, those systems likely have the AF_UNIX socketpair,
which tor prefers.)
Fixes bug #17638; bugfix on a very early tor version,
earlier than 22dba27d8d (23 Nov 2004) / svn:r2943.
Patch by "teor".
Make unit tests pass on IPv6-only systems, and systems without
localhost addresses (like some FreeBSD jails).
Fixes:
* get_if_addrs_ifaddrs: systems without localhost
* get_if_addrs_ioctl: only works on IPv4 systems
* socket: check IPv4 and IPv6, skip on EPROTONOSUPPORT
* socketpair_ersatz: uses IPv4, skip on EPROTONOSUPPORT
Fixes bug #17632; bugfix on unit tests in 0.2.7.3-rc.
c464a36772 was a partial fix for this issue in #17255;
it was released in unit tests in 0.2.7.4-rc.
