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.
Allow connections to single onion services to remain idle without being
disconnected.
Relays acting as rendezvous points for single onion services were
mistakenly closing idle established rendezvous circuits after 60 seconds,
thinking that they are unused directory-fetching circuits that had served
their purpose.
Fixes bug 29665; bugfix on 0.2.1.26.
Stop leaking parts of the shared random state in the shared-random unit
tests. The previous fix in 29599 was incomplete.
Fixes bug 29706; bugfix on 0.2.9.1-alpha.
Turns out that when reloading a tor configured with hidden service(s), we
weren't copying all the needed information between the old service object to
the new one.
For instance, the desc_is_dirty timestamp wasn't which could lead to the
service uploading its descriptor much later than it would need to.
The replaycache wasn't also moved over and some intro point information as
well.

Prior to #23100, we were not counting HS circuit build times in our
calculation of the timeout. This could lead to a condition where our timeout
was set too low, based on non HS circuit build times, and then we would
abandon all HS circuits, storing no valid timeouts in the histogram.
This commit avoids the assert.
malloc_options needs to be declared extern (and declaring it extern
means we need to initialize it separately)

Stop logging "Tried to establish rendezvous on non-OR circuit..." as
a warning. Instead, log it as a protocol warning, because there is
nothing that relay operators can do to fix it.
Fixes bug 29029; bugfix on 0.2.5.7-rc.
Merge Phoul's two lists into teor's list.
Replace the 150 fallbacks originally introduced in Tor 0.3.3.1-alpha in
January 2018 (of which ~115 were still functional), with a list of
157 fallbacks (92 new, 65 existing, 85 removed) generated in
December 2018.
Closes ticket 24803.

Correctly identify Windows 8.1, Windows 10, and Windows Server 2008
and later from their NT versions.
On recent Windows versions, the GetVersionEx() function may report
an earlier Windows version than the running OS. To avoid user
confusion, add "[or later]" to Tor's version string on affected
versions of Windows.
Remove Windows versions that were never supported by the
GetVersionEx() function.
Stop duplicating the latest Windows version in get_uname().
Fixes bug 28096; bugfix on 0.2.2.34; reported by Keifer Bly.
Apparently some freebsd compilers can't tell that 'c' will never
be used uninitialized.
Fixes bug 28413; bugfix on 0.2.9.3-alpha when we added support for
longer AES keys to this function.
Remember, you can't check to see if there are N bytes left in a
buffer by doing (buf + N < end), since the buf + N computation might
take you off the end of the buffer and result in undefined behavior.
Fixes 28202; bugfix on 0.2.0.3-alpha.
Treat backtrace test failures as expected on NetBSD, OpenBSD, and
macOS/Darwin, until we solve bug 17808.
(FreeBSD failures have been treated as expected since 18204 in 0.2.8.)
Fixes bug 27948; bugfix on 0.2.5.2-alpha.
Use the Travis Homebrew addon to install packages on macOS. The package
list is the same, but the Homebrew addon does not do a `brew update` by
default.
This makes builds faster, at the cost of using slightly older packages.
Implements ticket 27738.
On GCC and Clang, there's a feature to warn you about bad
conditionals like "if (a = b)", which should be "if (a == b)".
However, they don't warn you if there are extra parentheses around
"a = b".
Unfortunately, the tor_assert() macro and all of its kin have been
passing their inputs through stuff like PREDICT_UNLIKELY(expr) or
PREDICT_UNLIKELY(!(expr)), both of which expand to stuff with more
parentheses around "expr", thus suppressing these warnings.
To fix this, this patch introduces new macros that do not wrap
expr. They're only used when GCC or Clang is enabled (both define
__GNUC__), since they require GCC's "({statement expression})"
syntax extension. They're only used when we're building the
unit-test variant of the object files, since they suppress the
branch-prediction hints.
I've confirmed that tor_assert(), tor_assert_nonfatal(),
tor_assert_nonfatal_once(), BUG(), and IF_BUG_ONCE() all now give
compiler warnings when their argument is an assignment expression.
Fixes bug 27709.
Bugfix on 0.0.6, where we first introduced the "tor_assert()" macro.
