We don't want to accept any work after one of our worker functions has
returned WQ_RPL_SHUTDOWN. This testcase currently fails, because we do
not actually stop any of the worker threads.
We used to use this when we had some controllers that would accept
long names and some that wouldn't. But it's been obsolete for a
while, and it's time to strip it out of the code.
Previously we'd put these strings right on the controllers'
outbufs. But this could cause some trouble, for these reasons:
1) Calling the network stack directly here would make a huge portion
of our networking code (from which so much of the rest of Tor is
reachable) reachable from everything that potentially generated
controller events.
2) Since _some_ events (EVENT_ERR for instance) would cause us to
call connection_flush(), every control_event_* function would
appear to be able to reach even _more_ of the network stack in
our cllgraph.
3) Every time we generated an event, we'd have to walk the whole
connection list, which isn't exactly fast.
This is an attempt to break down the "blob" described in
http://archives.seul.org/tor/dev/Mar-2015/msg00197.html -- the set of
functions from which nearly all the other functions in Tor are
reachable.
Closes ticket 16695.
Test that TestingDirAuthVote{Exit,Guard,HSDir}[Strict] work on
routersets matching all routers, one router, and no routers.
TestingDirAuthVote{Exit,Guard,HSDir} set the corresponding flag
on routerstatuses which match the routerset, but leave other flags
unmodified.
TestingDirAuthVote{Exit,Guard,HSDir}Strict clear the corresponding flag
on routerstatuses which don't match the routerset.
Make it easier to unit test TestingDirAuthVote{Exit,Guard,HSDir}
by refactoring the code which sets flags based on them into a
new function dirserv_set_routerstatus_testing.
"option to prevent guard,exit,hsdir flag assignment"
"A node will never receive the corresponding flag unless
that node is specified in the
TestingDirAuthVote{Exit,Guard,HSDir} list, regardless of
its uptime, bandwidth, exit policy, or DirPort".
Patch modified by "teor": VoteOnHidServDirectoriesV2
is now obsolete, so TestingDirAuthVoteHSDir always
votes on HSDirs.
Closes ticket 14882. Patch by "robgjansen".

Fix an error in the manual page and comments for
TestingDirAuthVoteHSDir, which suggested that a
HSDir required "ORPort connectivity". While this is true,
it is in no way unique to the HSDir flag. Of all the flags,
only HSDirs need a DirPort configured in order for the
authorities to assign that particular flag.
Fixed as part of 14882. Patch by "teor".
Bugfix on 0.2.6.3 (f9d57473e1 on 10 January 2015).
This probably requires the user to manually set CFLAGS, but should
result in a net gain on 32 bit x86. Enabling SSE2 support would be
possible on x86_64, but will result in slower performance.
Implements feature #16535.
* FIXES#16823: https://bugs.torproject.org/16823
If an OP were to send a CREATE_FAST cell to an OR, and that
CREATE_FAST cell had unparseable key material, then tor_free() would
be called on the create cell twice. This fix removes the second
(conditional on the key material being bad) call to tor_free(), so
that now the create cell is always freed once, regardless of the status of
the key material.
(This isn't actually a double-free bug, since tor_free() sets its
input to NULL, and has no effect when called with input NULL.)
These scripts are now a little more bulletproof, cache data a little
better, and generate more information. Notably, they search for the
vectors or edges to cut that would lower the size of the largest
SCC.
