When classifying a client's selection of TLS ciphers, if the client
ciphers are not yet available, do not cache the result. Previously,
we had cached the unavailability of the cipher list and never looked
again, which in turn led us to assume that the client only supported
the ancient V1 link protocol. This, in turn, was causing Stem
integration tests to stall in some cases. Fixes bug 30021; bugfix
on 0.2.4.8-alpha.
When we fixed 28614, our answer was "if we failed to load the
consensus on windows and it had a CRLF, retry it." But we logged
the failure at "warn", and we only logged the retry at "info".
Now we log the retry at "notice", with more useful information.
Fixes bug 30004.
This is just in case there is some rogue platform that uses a
nonstandard value for SEEK_*, and does not define that macro in
unistd.h. I think that's unlikely, but it's conceivable.
Previously we used time(NULL) to set the Expires: header in our HTTP
responses. This made the actual contents of that header untestable,
since the unit tests have no good way to override time(), or to see
what time() was at the exact moment of the call to time() in
dircache.c.
This gave us a race in dir_handle_get/status_vote_next_bandwidth,
where the time() call in dircache.c got one value, and the call in
the tests got another value.
I'm applying our regular solution here: using approx_time() so that
the value stays the same between the code and the test. Since
approx_time() is updated on every event callback, we shouldn't be
losing any accuracy here.
Fixes bug 30001. Bug introduced in fb4a40c32c4a7e5; not in any
released Tor.
When a directory authority is using a bandwidth file to obtain the
bandwidth values that will be included in the next vote, serve this
bandwidth file at /tor/status-vote/next/bandwidth.z.
Let's use the same function exit point for BUG() codepath that we're using
for every other exit condition. That way, we're not forgetting to clean up
the memarea.
Previously, or_connection_t did not record whether or not the
connection uses a pluggable transport. Instead, it stored the
underlying proxy protocol of the pluggable transport in
proxy_type. This made bootstrap reporting treat pluggable transport
connections as plain proxy connections.
Store a separate bit indicating whether a pluggable transport is in
use, and decode this during bootstrap reporting.
Fixes bug 28925; bugfix on 0.4.0.1-alpha.
