We used to regenerate our descriptor whenever we'd get a sighup. This
was caused by a bug in options_transition_affects_workers() that would
return true even if the options were exactly the same. Down the call
path we'd call init_keys(), which made us make a new descriptor which
the authorities would reject, and the node would subsequently fall out
of the consensus.
This patch fixes only the first part of this bug:
options_transition_affects_workers() behaves correctly now. The second
part still wants a fix.
When we configure a new bridge via the controller, don't wait up to ten
seconds before trying to fetch its descriptor. This wasn't so bad when
you listed your bridges in torrc, but it's dreadful if you configure
your bridges via vidalia.
Bumped the char maximum to 512 for HTTPProxyAuthenticator &
HTTPSProxyAuthenticator. Now stripping all '\n' after base64
encoding in alloc_http_authenticator.
Rename crypto_pk_check_key_public_exponent to crypto_pk_public_exponent_ok:
it's nice to name predicates s.t. you can tell how to interpret true
and false.
Fixed a trivial conflict where this and the ControlSocketGroupWritable
code both added different functions to the same part of connection.c.
Conflicts:
src/or/connection.c
When running a system-wide instance of Tor on Unix-like systems, having
a ControlSocket is a quite handy mechanism to access Tor control
channel. But it would be easier if access to the Unix domain socket can
be granted by making control users members of the group running the Tor
process.
This change introduces a UnixSocketsGroupWritable option, which will
create Unix domain sockets (and thus ControlSocket) 'g+rw'. This allows
ControlSocket to offer same access control measures than
ControlPort+CookieAuthFileGroupReadable.
See <http://bugs.debian.org/552556> for more details.
This code changes it so that we don't remove bridges immediately when
we start re-parsing our configuration. Instead, we mark them all, and
remove all the marked ones after re-parsing our bridge lines. As we
add a bridge, we see if it's already in the list. If so, we just
unmark it.
This new behavior will lose the property we used to have that bridges
were in bridge_list in the same order in which they appeared in the
torrc. I took a quick look through the code, and I'm pretty sure we
didn't actually depend on that anywhere.
This is for bug 3019; it's a fix on 0.2.0.3-alpha.
rransom notes correctly that now that we aren't checking our HSDir
flag, we have no actual reason to check whether we are listed in the
consensus at all when determining if we should act like a hidden
service directory.
Previously, if they changed in torrc during a SIGHUP, all was well,
since we would just clear all transient entries from the addrmap
thanks to bug 1345. But if you changed them from the controller, Tor
would leave old mappings in place.
The VirtualAddrNetwork bug has been here since 0.1.1.19-rc; the
AutomapHosts* bug has been here since 0.2.0.1-alpha.
This bug couldn't happen when TrackExitHosts changed in torrc, since
the SIGHUP to reload the torrc would clear out all the transient
addressmap entries before. But if you used SETCONF to change
TrackExitHosts, old entries would be left alone: that's a bug, and so
this is a bugfix on Tor 0.1.0.1-rc.
If you really want to purge the client DNS cache, the TrackHostExits
mappings, and the virtual address mappings, you should be using NEWNYM
instead.
Fixes bug 1345; bugfix on Tor 0.1.0.1-rc.
Note that this needs more work: now that we aren't nuking the
transient addressmap entries on HUP, we need to make sure that
configuration changes to VirtualAddressMap and TrackHostExits actually
have a reasonable effect.
We'll eventually want to do more work here to make sure that the ports
are stable over multiple invocations. Otherwise, turning your node on
and off will get you a new DirPort/ORPort needlessly.
Otherwise, it will just immediately close any port declared with "auto"
on the grounds that it wasn't configured. Now, it will allow "auto" to
match any port.
This means FWIW if you configure a socks port with SocksPort 9999
and then transition to SocksPort auto, the original socksport will
not get closed and reopened. I'm considering this a feature.
HTTPS error code 403 is now reported as:
"The https proxy refused to allow connection".
Used a switch statement for additional error codes to be explained
in the future.
The old behavior contributed to unreliability when hidden services and
hsdirs had different consensus versions, and so had different opinions
about who should be cacheing hsdir info.
Bugfix on 0.2.0.10-alpha; based on discussions surrounding bug 2732.
