Many buffer functions have a hard limit of INT_MAX for datalen, but
this limitation is not enforced in all functions:
- buf_move_all may exceed that limit with too many chunks
- buf_move_to_buf exceeds that limit with invalid buf_flushlen argument
- buf_new_with_data may exceed that limit (unit tests only)
This patch adds some annotations in some buf_pos_t functions to
guarantee that no out of boundary access could occur even if another
function lacks safe guards against datalen overflows.
[This is a backport of the submitted patch to 0.2.9, where the
buf_move_to_buf and buf_new_with_data functions did not exist.]
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.
Since we have moved coveralls to the script target the entire build will
now fail if coveralls fail. We handle it more gracefully by echo'ing the
failure instead of doing a hard-failure.

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.
Apparently, even though the manpage says it returns an int, it
can return a long instead and cause a warning.
Bug not in any released Tor. Part of #28399
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.
