Now, when a user who has set EntryNodes finishes bootstrapping, Tor
automatically repopulates the guard set based on this new directory
information. Fixes bug 16825; bugfix on 0.2.3.1-alpha.
If unix socket was configured as listener (such as a ControlSocket or a
SocksPort unix socket), and tor was started as root but not configured
to switch to another user, tor would segfault while trying to string
compare a NULL value. Fixes bug 18261; bugfix on 0.2.8.1-alpha. Patch
by weasel.
We use sensible parameters taken from common sources, and no longer
have dynamic DH groups as an option, but it feels prudent to have
OpenSSL validate p and g at initialization time.
We've never actually tested this support, and we should probably assume
it's broken.
To the best of my knowledge, only OpenVMS has this, and even on
OpenVMS it's a compile-time option to disable it. And I don't think
we build on openvms anyway. (Everybody else seems to be working
around the 2038 problem by using a 64-bit time_t, which won't expire
for roughly 292 billion years.)
Closes ticket 18184.
ClientUseIPv4 0 tells tor to avoid IPv4 client connections.
ClientPreferIPv6DirPort 1 tells tor to prefer IPv6 directory connections.
Refactor policy for IPv4/IPv6 preferences.
Fix a bug where node->ipv6_preferred could become stale if
ClientPreferIPv6ORPort was changed after the consensus was loaded.
Update documentation, existing code, add unit tests.
This closes bug 18162; bugfix on a45b131590, which fixed a related
issue long ago.
In addition to the #18162 issues, this fixes a signed integer overflow
in smarltist_add_all(), which is probably not so great either.
Allow fallback directories which have been stable for 30 days
to work around #18050, which causes relays to submit descriptors
with 0 DirPorts when restarted. (Particularly during Tor version
upgrades.)
Ignore low fallback directory count in alpha builds.
