557f332957 Fix a bug in our bug 9776 fix. 
By calling circuit_n_chan_done() unconditionally on close, we were
closing pending connections that might not have been pending quite for
the connection we were closing.  Fix for bug 9880.

Thanks to skruffy for finding this and explaining it patiently until
we understood.

d1dbaf2473 Relays should send timestamp in NETINFO.

4f036acd27 back out most of 1d0ba9a 
this was causing directory authorities to send a time of 0 on all
connections they generated themselves, which means everybody reachability
test caused a time skew warning in the log for that relay.

(i didn't just revert, because the changes file has been modified by
other later commits.)

fd2954d06d Round down hidden service descriptor publication times to nearest hour

accadd8752 Remove the timestamp from AUTHENTICATE cells; replace with random bytes 
This isn't actually much of an issue, since only relays send
AUTHENTICATE cells, but while we're removing timestamps, we might as
well do this too.

Part of proposal 222.  I didn't take the approach in the proposal of
using a time-based HMAC, since that was a bad-prng-mitigation hack
from SSL3, and in real life, if you don't have a good RNG, you're
hopeless as a Tor server.

f8b44eedf7 Get ready to stop sending timestamps in INTRODUCE cells 
For now, round down to the nearest 10 minutes.  Later, eliminate entirely by
setting a consensus parameter.

(This rounding is safe because, in 0.2.2, where the timestamp mattered,
REND_REPLAY_TIME_INTERVAL was a nice generous 60 minutes.)

7dbf66713f When freeing a cert_list_t, avoid memory leak. 
We were freeing these on exit, but when we added the dl_status_map
field to them in fddb814f, we forgot to arrange for it to be freed.

I've moved the cert_list_free() code into its own function, and added
an appropriate dsmap_free() call.

dece40fd77 Fix an assert when disabling ORPort with accounting disabled. 
The problem was that the server_identity_key_is_set() function could
return true under conditions where we don't really have an identity
key -- specifically, where we used to have one, but we stopped being a
server.

This is a fix for 6979; bugfix on 0.2.2.18-alpha where we added that
assertion to get_server_identity_key().

15b9a1ff10 Correctly re-process non-option cmdline args on sighup 
Whenever we had an non-option commandline arguments *and*
option-bearing commandline arguments on the commandline, we would save
only the latter across invocations of options_init_from_torrc, but
take their existence as license not to re-parse the former.  Yuck!

Incidentally, this fix lets us throw away the backup_arg[gv] logic.

Fix for bug 9746; bugfix on d98dfb3746,

a2754d418d Try using INT_MAX, not SOMAXCONN, to set listen() backlog. 
Fall back to SOMAXCONN if INT_MAX doesn't work.

We'd like to do this because the actual maximum is overrideable by the
kernel, and the value in the header file might not be right at all.
All implementations I can find out about claim that this is supported.

This would make us do testing circuits "even when cbt is disabled by
consensus, or when we're a directory authority, or when we've failed

(Backport to Tor 0.2.3)

Relays previously, when initiating a connection, would only send a
NETINFO after sending an AUTHENTICATE.  But bridges, when receiving a
connection, would never send AUTH_CHALLENGE.  So relays wouldn't
AUTHENTICATE, and wouldn't NETINFO, and then bridges would be
surprised to be receiving CREATE cells on a non-open circuit.

1bb4a4f9bd Send NETINFO on receiving a NETINFO if we have not yet sent one. 
Relays previously, when initiating a connection, would only send a
NETINFO after sending an AUTHENTICATE.  But bridges, when receiving a
connection, would never send AUTH_CHALLENGE.  So relays wouldn't
AUTHENTICATE, and wouldn't NETINFO, and then bridges would be
surprised to be receiving CREATE cells on a non-open circuit.

Fixes bug 9546.

17e9fc09c3 Coverage support: build with --enable-coverage to have tests run with gcov 
If you pass the --enable-coverage flag on the command line, we build
our testing binaries with appropriate options eo enable coverage
testing.  We also build a "tor-cov" binary that has coverage enabled,
for integration tests.

On recent OSX versions, test coverage only works with clang, not gcc.
So we warn about that.

Also add a contrib/coverage script to actually run gcov with the
appropriate options to generate useful .gcov files.  (Thanks to
automake, the .o files will not have the names that gcov expects to
find.)

Also, remove generated gcda and gcno files on clean.

a3e0a87d95 Completely refactor how FILENAME_PRIVATE works 
We previously used FILENAME_PRIVATE identifiers mostly for
identifiers exposed only to the unit tests... but also for
identifiers exposed to the benchmarker, and sometimes for
identifiers exposed to a similar module, and occasionally for no
really good reason at all.

Now, we use FILENAME_PRIVATE identifiers for identifiers shared by
Tor and the unit tests.  They should be defined static when we
aren't building the unit test, and globally visible otherwise. (The
STATIC macro will keep us honest here.)

For identifiers used only by the unit tests and never by Tor at all,
on the other hand, we wrap them in #ifdef TOR_UNIT_TESTS.

This is not the motivating use case for the split test/non-test
build system; it's just a test example to see how it works, and to
take a chance to clean up the code a little.

f7d654b81e Start work on fancy compiler tricks to expose extra stuff to our tests 
This is mainly a matter of automake trickery: we build each static
library in two versions now: one with the TOR_UNIT_TESTS macro
defined, and one without.  When TOR_UNIT_TESTS is defined, we can
enable mocking and expose more functions. When it's not defined, we
can lock the binary down more.

The alternatives would be to have alternate build modes: a "testing
configuration" for building the libraries with test support, and a
"production configuration" for building them without.  I don't favor
that approach, since I think it would mean more people runnning
binaries build for testing, or more people not running unit tests.

behavior has been wrong for a while.)

2e1fe1fcf9 Implement a real OOM-killer for too-long circuit queues. 
This implements "algorithm 1" from my discussion of bug #9072: on OOM,
find the circuits with the longest queues, and kill them.  It's also a
fix for #9063 -- without the side-effects of bug #9072.

The memory bounds aren't perfect here, and you need to be sure to
allow some slack for the rest of Tor's usage.

This isn't a perfect fix; the rest of the solutions I describe on
codeable.

DESTROYs.
