Tor 0.2.9 has a broader range of fixes and workarounds here, but for
0.2.8, we're just going to maintain the existing behavior.
(The alternative would be to backport both
1eba088054 and
16fcbd21c9 , but the latter is kind of
a subtle kludge in the configure.ac script, and I'm not a fan of
backporting that kind of thing.)
(OpenSSL 1.1 makes EVP_CIPHER_CTX opaque, _and_ adds acceleration
for counter mode on more architectures. So it won't work if we try
the older approach, and it might help if we try the newer one.)
Fixes bug 20588.
When computing old Tor protocol line version in protover, we were looking at
0.2.7.5 twice instead of the specific case for 0.2.9.1-alpha.
Fixes#20810

Coverity doesn't like it when there are paths to the end of the
function where something doesn't get freed, even when those paths
are only reachable on unit test failure.
Fixes CID 1372899 and CID 1372900. Bug not in any released Tor.
newconn->address is strdup'ed twice when new_type == CONN_TYPE_AP
and conn->socket_family == AF_UNIX. Whilst here, juggle code to
make sure newconn->port is assigned from an initialised value in
the above case.
Instead, refuse to start tor if any hidden service key has been used in
a different hidden service anonymity mode.
Fixes bug 20638; bugfix on 17178 in 0.2.9.3-alpha; reported by ahf.
The original single onion service poisoning code checked poisoning state
in options_validate, and poisoned in options_act. This was problematic,
because the global array of hidden services had not been populated in
options_validate (and there were ordrering issues with hidden service
directory creation).
This patch fixes this issue in rend_service_check_dir_and_add, which:
* creates the directory, or checks permissions on an existing directory, then
* checks the poisoning state of the directory, then
* poisons the directory.
When validating, only the permissions checks and the poisoning state checks
are perfomed (the directory is not modified).
(We only create HS directories if we are acting on the config.)
Log a BUG warning if the directories aren't present immediately before they
are used, then fail.
For relays that don't know their own address, avoid attempting
a local hostname resolve for each descriptor we download. Also cut
down on the number of "Success: chose address 'x.x.x.x'" log lines.
Fixes bugs 20423 and 20610; bugfix on 0.2.8.1-alpha.
Single onion services and Tor2web deliberately create long-term one-hop
circuits to their intro and rend points, respectively.
These log messages are intended to diagnose issue 8387, which relates to
circuits hanging around forever for no reason.
Fixes bug 20613; bugfix on 0.2.9.1-alpha. Reported by "pastly".
It's not okay to use the same varargs list twice, and apparently
some windows build environments produce code here that would leave
tor_asprintf() broken. Fix for bug 20560; bugfix on 0.2.2.11-alpha
when tor_asprintf() was introduced.
Because as Teor puts it: "[Resetting on 503] is exactly what we
don't want when relays are busy - imagine clients doing an automatic
reset every time they DoS a relay..."
Fixes bug 20593.
