   Log Message:
   tor: update to 0.2.9.8
   Updated provided by reezer (maintainer) in PR pkg/51745

   Changes in version 0.2.9.8 - 2016-12-19
    Tor 0.2.9.8 is the first stable release of the Tor 0.2.9 series.

    The Tor 0.2.9 series makes mandatory a number of security features
    that were formerly optional. It includes support for a new shared-
    randomness protocol that will form the basis for next generation
    hidden services, includes a single-hop hidden service mode for
    optimizing .onion services that don't actually want to be hidden,
    tries harder not to overload the directory authorities with excessive
    downloads, and supports a better protocol versioning scheme for
    improved compatibility with other implementations of the Tor protocol.

    And of course, there are numerous other bugfixes and improvements.

    This release also includes a fix for a medium-severity issue (bug
    21018 below) where Tor clients could crash when attempting to visit a
    hostile hidden service. Clients are recommended to upgrade as packages
    become available for their systems.

    Below are listed the changes since Tor 0.2.8.11.  For a list of
    changes since 0.2.9.7-rc, see the ChangeLog file.

    o New system requirements:
      - When building with OpenSSL, Tor now requires version 1.0.1 or
        later. OpenSSL 1.0.0 and earlier are no longer supported by the
        OpenSSL team, and should not be used. Closes ticket 20303.
      - Tor now requires Libevent version 2.0.10-stable or later. Older
        versions of Libevent have less efficient backends for several
        platforms, and lack the DNS code that we use for our server-side
        DNS support. This implements ticket 19554.
      - Tor now requires zlib version 1.2 or later, for security,
        efficiency, and (eventually) gzip support. (Back when we started,
        zlib 1.1 and zlib 1.0 were still found in the wild. 1.2 was
        released in 2003. We recommend the latest version.)

    o Deprecated features:
      - A number of DNS-cache-related sub-options for client ports are now
        deprecated for security reasons, and may be removed in a future
        version of Tor. (We believe that client-side DNS caching is a bad
        idea for anonymity, and you should not turn it on.) The options
        are: CacheDNS, CacheIPv4DNS, CacheIPv6DNS, UseDNSCache,
        UseIPv4Cache, and UseIPv6Cache.
      - A number of options are deprecated for security reasons, and may
        be removed in a future version of Tor. The options are:
        AllowDotExit, AllowInvalidNodes, AllowSingleHopCircuits,
        AllowSingleHopExits, ClientDNSRejectInternalAddresses,
        CloseHSClientCircuitsImmediatelyOnTimeout,
        CloseHSServiceRendCircuitsImmediatelyOnTimeout,
        ExcludeSingleHopRelays, FastFirstHopPK, TLSECGroup,
        UseNTorHandshake, and WarnUnsafeSocks.
      - The *ListenAddress options are now deprecated as unnecessary: the
        corresponding *Port options should be used instead. These options
        may someday be removed. The affected options are:
        ControlListenAddress, DNSListenAddress, DirListenAddress,
        NATDListenAddress, ORListenAddress, SocksListenAddress,
        and TransListenAddress.

    o Major bugfixes (parsing, security, new since 0.2.9.7-rc):
      - Fix a bug in parsing that could cause clients to read a single
        byte past the end of an allocated region. This bug could be used
        to cause hardened clients (built with --enable-expensive-hardening)
        to crash if they tried to visit a hostile hidden service. Non-
        hardened clients are only affected depending on the details of
        their platform's memory allocator. Fixes bug 21018; bugfix on
        0.2.0.8-alpha. Found by using libFuzzer. Also tracked as TROVE-
        2016-12-002 and as CVE-2016-1254.

    o Major features (build, hardening):
      - Tor now builds with -ftrapv by default on compilers that support
        it. This option detects signed integer overflow (which C forbids),
        and turns it into a hard-failure. We do not apply this option to
        code that needs to run in constant time to avoid side-channels;
        instead, we use -fwrapv in that code. Closes ticket 17983.
      - When --enable-expensive-hardening is selected, stop applying the
        clang/gcc sanitizers to code that needs to run in constant time.
        Although we are aware of no introduced side-channels, we are not
        able to prove that there are none. Related to ticket 17983.

    o Major features (circuit building, security):
      - Authorities, relays, and clients now require ntor keys in all
        descriptors, for all hops (except for rare hidden service protocol
        cases), for all circuits, and for all other roles. Part of
        ticket 19163.
      - Authorities, relays, and clients only use ntor, except for
        rare cases in the hidden service protocol. Part of ticket 19163.

    o Major features (compilation):
      - Our big list of extra GCC warnings is now enabled by default when
        building with GCC (or with anything like Clang that claims to be
        GCC-compatible). To make all warnings into fatal compilation
        errors, pass --enable-fatal-warnings to configure. Closes
        ticket 19044.
      - Use the Autoconf macro AC_USE_SYSTEM_EXTENSIONS to automatically
        turn on C and POSIX extensions. (Previously, we attempted to do
        this on an ad hoc basis.) Closes ticket 19139.

    o Major features (directory authorities, hidden services):
      - Directory authorities can now perform the shared randomness
        protocol specified by proposal 250. Using this protocol, directory
        authorities generate a global fresh random value every day. In the
        future, this value will be used by hidden services to select
        HSDirs. This release implements the directory authority feature;
        the hidden service side will be implemented in the future as part
        of proposal 224. Resolves ticket 16943; implements proposal 250.

    o Major features (downloading, random exponential backoff):
      - When we fail to download an object from a directory service, wait
        for an (exponentially increasing) randomized amount of time before
        retrying, rather than a fixed interval as we did before. This
        prevents a group of Tor instances from becoming too synchronized,
        or a single Tor instance from becoming too predictable, in its
        download schedule. Closes ticket 15942.

    o Major features (resource management):
      - Tor can now notice it is about to run out of sockets, and
        preemptively close connections of lower priority. (This feature is
        off by default for now, since the current prioritizing method is
        yet not mature enough. You can enable it by setting
        "DisableOOSCheck 0", but watch out: it might close some sockets
        you would rather have it keep.) Closes ticket 18640.

    o Major features (single-hop "hidden" services):
      - Add experimental HiddenServiceSingleHopMode and
        HiddenServiceNonAnonymousMode options. When both are set to 1,
        every hidden service on that Tor instance becomes a non-anonymous
        Single Onion Service. Single Onions make one-hop (direct)
        connections to their introduction and rendezvous points. One-hop
        circuits make Single Onion servers easily locatable, but clients
        remain location-anonymous. This is compatible with the existing
        hidden service implementation, and works on the current Tor
        network without any changes to older relays or clients. Implements
        proposal 260, completes ticket 17178. Patch by teor and asn.

    o Major features (subprotocol versions):
      - Tor directory authorities now vote on a set of recommended
        "subprotocol versions", and on a set of required subprotocol
        versions. Clients and relays that lack support for a _required_
        subprotocol version will not start; those that lack support for a
        _recommended_ subprotocol version will warn the user to upgrade.
        This change allows compatible implementations of the Tor protocol(s)
        to exist without pretending to be 100% bug-compatible with
        particular releases of Tor itself. Closes ticket 19958; implements
        part of proposal 264.

    o Major bugfixes (circuit building):
      - Hidden service client-to-intro-point and service-to-rendezvous-
        point circuits use the TAP key supplied by the protocol, to avoid
        epistemic attacks. Fixes bug 19163; bugfix on 0.2.4.18-rc.

    o Major bugfixes (download scheduling):
      - Avoid resetting download status for consensuses hourly, since we
        already have another, smarter retry mechanism. Fixes bug 8625;
        bugfix on 0.2.0.9-alpha.
      - If a consensus expires while we are waiting for certificates to
        download, stop waiting for certificates.
      - If we stop waiting for certificates less than a minute after we
        started downloading them, do not consider the certificate download
        failure a separate failure. Fixes bug 20533; bugfix
        on 0.2.0.9-alpha.
      - When using exponential backoff in test networks, use a lower
        exponent, so the delays do not vary as much. This helps test
        networks bootstrap consistently. Fixes bug 20597; bugfix on 20499.

    o Major bugfixes (exit policies):
      - Avoid disclosing exit outbound bind addresses, configured port
        bind addresses, and local interface addresses in relay descriptors
        by default under ExitPolicyRejectPrivate. Instead, only reject
        these (otherwise unlisted) addresses if
        ExitPolicyRejectLocalInterfaces is set. Fixes bug 18456; bugfix on
        0.2.7.2-alpha. Patch by teor.

    o Major bugfixes (hidden services):
      - Allow Tor clients with appropriate controllers to work with
        FetchHidServDescriptors set to 0. Previously, this option also
        disabled descriptor cache lookup, thus breaking hidden services
        entirely. Fixes bug 18704; bugfix on 0.2.0.20-rc. Patch by "twim".
      - Clients now require hidden services to include the TAP keys for
        their intro points in the hidden service descriptor. This prevents
        an inadvertent upgrade to ntor, which a malicious hidden service
        could use to distinguish clients by consensus version. Fixes bug
        20012; bugfix on 0.2.4.8-alpha. Patch by teor.

    o Major bugfixes (relay, resolver, logging):
      - For relays that don't know their own address, avoid attempting a
        local hostname resolve for each descriptor we download. This
        will cut down on the number of "Success: chose address 'x.x.x.x'"
        log lines, and also avoid confusing clock jumps if the resolver
        is slow. Fixes bugs 20423 and 20610; bugfix on 0.2.8.1-alpha.

    o Minor features (port flags):
      - Add new flags to the *Port options to give finer control over which
        requests are allowed. The flags are NoDNSRequest, NoOnionTraffic,
        and the synthetic flag OnionTrafficOnly, which is equivalent to
        NoDNSRequest, NoIPv4Traffic, and NoIPv6Traffic. Closes enhancement
        18693; patch by "teor".

    o Minor features (build, hardening):
      - Detect and work around a libclang_rt problem that would prevent
        clang from finding __mulodi4() on some 32-bit platforms, and thus
        keep -ftrapv from linking on those systems. Closes ticket 19079.
      - When building on a system without runtime support for the runtime
        hardening options, try to log a useful warning at configuration
        time, rather than an incomprehensible warning at link time. If
        expensive hardening was requested, this warning becomes an error.
        Closes ticket 18895.

    o Minor features (client, directory):
      - Since authorities now omit all routers that lack the Running and
        Valid flags, we assume that any relay listed in the consensus must
        have those flags. Closes ticket 20001; implements part of
        proposal 272.

    o Minor features (code safety):
      - In our integer-parsing functions, ensure that the maximum value we
        allow is no smaller than the minimum value. Closes ticket 19063;
        patch from "U+039b".

    o Minor features (compilation, portability):
      - Compile correctly on MacOS 10.12 (aka "Sierra"). Closes
        ticket 20241.

    o Minor features (config):
      - Warn users when descriptor and port addresses are inconsistent.
        Mitigates bug 13953; patch by teor.

    o Minor features (controller):
      - Allow controllers to configure basic client authorization on
        hidden services when they create them with the ADD_ONION controller
        command. Implements ticket 15588. Patch by "special".
      - Fire a STATUS_SERVER controller event whenever the hibernation
        status changes between "awake"/"soft"/"hard". Closes ticket 18685.
      - Implement new GETINFO queries for all downloads that use
        download_status_t to schedule retries. This allows controllers to
        examine the schedule for pending downloads. Closes ticket 19323.

    o Minor features (development tools, etags):
      - Teach the "make tags" Makefile target how to correctly find
        "MOCK_IMPL" function definitions. Patch from nherring; closes
        ticket 16869.

    o Minor features (directory authority):
      - After voting, if the authorities decide that a relay is not
        "Valid", they no longer include it in the consensus at all. Closes
        ticket 20002; implements part of proposal 272.
      - Directory authorities now only give the Guard flag to a relay if
        they are also giving it the Stable flag. This change allows us to
        simplify path selection for clients. It should have minimal effect
        in practice, since >99% of Guards already have the Stable flag.
        Implements ticket 18624.
      - Directory authorities now write their v3-status-votes file out to
        disk earlier in the consensus process, so we have a record of the
        votes even if we abort the consensus process. Resolves
        ticket 19036.

    o Minor features (fallback directory list, new since 0.2.9.7-rc):
      - Replace the 81 remaining fallbacks of the 100 originally
        introduced in Tor 0.2.8.3-alpha in March 2016, with a list of 177
        fallbacks (123 new, 54 existing, 27 removed) generated in December
        2016. Resolves ticket 20170.

    o Minor features (hidden service):
      - Stop being so strict about the payload length of "rendezvous1"
        cells. We used to be locked in to the "TAP" handshake length, and
        now we can handle better handshakes like "ntor". Resolves
        ticket 18998.

    o Minor features (infrastructure, time):
      - Tor now includes an improved timer backend, so that we can
        efficiently support tens or hundreds of thousands of concurrent
        timers, as will be needed for some of our planned anti-traffic-
        analysis work. This code is based on William Ahern's "timeout.c"
        project, which implements a "tickless hierarchical timing wheel".
        Closes ticket 18365.
      - Tor now uses the operating system's monotonic timers (where
        available) for internal fine-grained timing. Previously we would
        look at the system clock, and then attempt to compensate for the
        clock running backwards. Closes ticket 18908.

    o Minor features (logging):
      - Add a set of macros to check nonfatal assertions, for internal
        use. Migrating more of our checks to these should help us avoid
        needless crash bugs. Closes ticket 18613.
      - Provide a more useful warning message when configured with an
        invalid Nickname. Closes ticket 18300; patch from "icanhasaccount".
      - When dumping unparseable router descriptors, optionally store them
        in separate files, named by digest, up to a configurable size
        limit. You can change the size limit by setting the
        MaxUnparseableDescSizeToLog option, and disable this feature by
        setting that option to 0. Closes ticket 18322.

    o Minor features (performance):
      - Change the "optimistic data" extension from "off by default" to
        "on by default". The default was ordinarily overridden by a
        consensus option, but when clients were bootstrapping for the
        first time, they would not have a consensus to get the option
        from. Changing this default saves a round-trip during startup.
        Closes ticket 18815.

    o Minor features (relay, usability):
      - When the directory authorities refuse a bad relay's descriptor,
        encourage the relay operator to contact us. Many relay operators
        won't notice this line in their logs, but it's a win if even a few
        learn why we don't like what their relay was doing. Resolves
        ticket 18760.

    o Minor features (security, TLS):
      - Servers no longer support clients that lack AES ciphersuites.
        (3DES is no longer considered an acceptable cipher.) We believe
        that no such Tor clients currently exist, since Tor has required
        OpenSSL 0.9.7 or later since 2009. Closes ticket 19998.

    o Minor features (testing):
      - Disable memory protections on OpenBSD when performing our unit
        tests for memwipe(). The test deliberately invokes undefined
        behavior, and the OpenBSD protections interfere with this. Patch
        from "rubiate". Closes ticket 20066.
      - Move the test-network.sh script to chutney, and modify tor's test-
        network.sh to call the (newer) chutney version when available.
        Resolves ticket 19116. Patch by teor.
      - Use the lcov convention for marking lines as unreachable, so that
        we don't count them when we're generating test coverage data.
        Update our coverage tools to understand this convention. Closes
        ticket 16792.
      - Our link-handshake unit tests now check that when invalid
        handshakes fail, they fail with the error messages we expected.
      - Our unit testing code that captures log messages no longer
        prevents them from being written out if the user asked for them
        (by passing --debug or --info or --notice or --warn to the "test"
        binary). This change prevents us from missing unexpected log
        messages simply because we were looking for others. Related to
        ticket 19999.
      - The unit tests now log all warning messages with the "BUG" flag.
        Previously, they only logged errors by default. This change will
        help us make our testing code more correct, and make sure that we
        only hit this code when we mean to. In the meantime, however,
        there will be more warnings in the unit test logs than before.
        This is preparatory work for ticket 19999.
      - The unit tests now treat any failure of a "tor_assert_nonfatal()"
        assertion as a test failure.
      - We've done significant work to make the unit tests run faster.

    o Minor features (testing, ipv6):
      - Add the hs-ipv6 chutney target to make test-network-all's IPv6
        tests. Remove bridges+hs, as it's somewhat redundant. This
        requires a recent chutney version that supports IPv6 clients,
        relays, and authorities. Closes ticket 20069; patch by teor.
      - Add the single-onion and single-onion-ipv6 chutney targets to
        "make test-network-all". This requires a recent chutney version
        with the single onion network flavors (git c72a652 or later).
        Closes ticket 20072; patch by teor.

    o Minor features (Tor2web):
      - Make Tor2web clients respect ReachableAddresses. This feature was
        inadvertently enabled in 0.2.8.6, then removed by bugfix 19973 on
        0.2.8.7. Implements feature 20034. Patch by teor.

    o Minor features (unix domain sockets):
      - When configuring a unix domain socket for a SocksPort,
        ControlPort, or Hidden service, you can now wrap the address in
        quotes, using C-style escapes inside the quotes. This allows unix
        domain socket paths to contain spaces. Resolves ticket 18753.

    o Minor features (user interface):
      - Tor now supports the ability to declare options deprecated, so
        that we can recommend that people stop using them. Previously, this
        was done in an ad-hoc way. There is a new --list-deprecated-options
        command-line option to list all of the deprecated options. Closes
        ticket 19820.

    o Minor features (virtual addresses):
      - Increase the maximum number of bits for the IPv6 virtual network
        prefix from 16 to 104. In this way, the condition for address
        allocation is less restrictive. Closes ticket 20151; feature
        on 0.2.4.7-alpha.

    o Minor bug fixes (circuits):
      - Use the CircuitBuildTimeout option whenever
        LearnCircuitBuildTimeout is disabled. Previously, we would respect
        the option when a user disabled it, but not when it was disabled
        because some other option was set. Fixes bug 20073; bugfix on
        0.2.4.12-alpha. Patch by teor.

    o Minor bugfixes (build):
      - The current Git revision when building from a local repository is
        now detected correctly when using git worktrees. Fixes bug 20492;
        bugfix on 0.2.3.9-alpha.

    o Minor bugfixes (relay address discovery):
      - Stop reordering IP addresses returned by the OS. This makes it
        more likely that Tor will guess the same relay IP address every
        time. Fixes issue 20163; bugfix on 0.2.7.1-alpha, ticket 17027.
        Reported by René Mayrhofer, patch by "cypherpunks".

    o Minor bugfixes (memory allocation):
      - Change how we allocate memory for large chunks on buffers, to
        avoid a (currently impossible) integer overflow, and to waste less
        space when allocating unusually large chunks. Fixes bug 20081;
        bugfix on 0.2.0.16-alpha. Issue identified by Guido Vranken.

    o Minor bugfixes (bootstrap):
      - Remember the directory server we fetched the consensus or previous
        certificates from, and use it to fetch future authority
        certificates. This change improves bootstrapping performance.
        Fixes bug 18963; bugfix on 0.2.8.1-alpha.

    o Minor bugfixes (circuits):
      - Make sure extend_info_from_router() is only called on servers.
        Fixes bug 19639; bugfix on 0.2.8.1-alpha.

    o Minor bugfixes (client, fascistfirewall):
      - Avoid spurious warnings when ReachableAddresses or FascistFirewall
        is set. Fixes bug 20306; bugfix on 0.2.8.2-alpha.

    o Minor bugfixes (client, unix domain sockets):
      - Disable IsolateClientAddr when using AF_UNIX backed SocksPorts as
        the client address is meaningless. Fixes bug 20261; bugfix
        on 0.2.6.3-alpha.

    o Minor bugfixes (code style):
      - Fix an integer signedness conversion issue in the case conversion
        tables. Fixes bug 19168; bugfix on 0.2.1.11-alpha.

    o Minor bugfixes (compilation):
      - Build correctly on versions of libevent2 without support for
        evutil_secure_rng_add_bytes(). Fixes bug 19904; bugfix
        on 0.2.5.4-alpha.
      - When building with Clang, use a full set of GCC warnings.
        (Previously, we included only a subset, because of the way we
        detected them.) Fixes bug 19216; bugfix on 0.2.0.1-alpha.
      - Detect Libevent2 functions correctly on systems that provide
        libevent2, but where libevent1 is linked with -levent. Fixes bug
        19904; bugfix on 0.2.2.24-alpha. Patch from Rubiate.
      - Run correctly when built on Windows build environments that
        require _vcsprintf(). Fixes bug 20560; bugfix on 0.2.2.11-alpha.

    o Minor bugfixes (configuration):
      - When parsing quoted configuration values from the torrc file,
        handle Windows line endings correctly. Fixes bug 19167; bugfix on
        0.2.0.16-alpha. Patch from "Pingl".

    o Minor bugfixes (directory authority):
      - Authorities now sort the "package" lines in their votes, for ease
        of debugging. (They are already sorted in consensus documents.)
        Fixes bug 18840; bugfix on 0.2.6.3-alpha.
      - Die with a more useful error when the operator forgets to place
        the authority_signing_key file into the keys directory. This
        avoids an uninformative assert & traceback about having an invalid
        key. Fixes bug 20065; bugfix on 0.2.0.1-alpha.
      - When allowing private addresses, mark Exits that only exit to
        private locations as such. Fixes bug 20064; bugfix
        on 0.2.2.9-alpha.
      - When parsing a detached signature, make sure we use the length of
        the digest algorithm instead of a hardcoded DIGEST256_LEN in
        order to avoid comparing bytes out-of-bounds with a smaller digest
        length such as SHA1. Fixes bug 19066; bugfix on 0.2.2.6-alpha.

    o Minor bugfixes (getpass):
      - Defensively fix a non-triggerable heap corruption at do_getpass()
        to protect ourselves from mistakes in the future. Fixes bug
        19223; bugfix on 0.2.7.3-rc. Bug found by Guido Vranken, patch
        by nherring.

    o Minor bugfixes (guard selection):
      - Don't mark guards as unreachable if connection_connect() fails.
        That function fails for local reasons, so it shouldn't reveal
        anything about the status of the guard. Fixes bug 14334; bugfix
        on 0.2.3.10-alpha.
      - Use a single entry guard even if the NumEntryGuards consensus
        parameter is not provided. Fixes bug 17688; bugfix
        on 0.2.5.6-alpha.

    o Minor bugfixes (hidden services):
      - Increase the minimum number of internal circuits we preemptively
        build from 2 to 3, so a circuit is available when a client
        connects to another onion service. Fixes bug 13239; bugfix
        on 0.1.0.1-rc.
      - Allow hidden services to run on IPv6 addresses even when the
        IPv6Exit option is not set. Fixes bug 18357; bugfix
        on 0.2.4.7-alpha.
      - Stop logging intro point details to the client log on certain
        error conditions. Fixed as part of bug 20012; bugfix on
        0.2.4.8-alpha. Patch by teor.
      - When deleting an ephemeral hidden service, close its intro points
        even if they are not completely open. Fixes bug 18604; bugfix
        on 0.2.7.1-alpha.
      - When configuring hidden services, check every hidden service
        directory's permissions. Previously, we only checked the last
        hidden service. Fixes bug 20529; bugfix on 0.2.6.2-alpha.

    o Minor bugfixes (IPv6, testing):
      - Check for IPv6 correctly on Linux when running test networks.
        Fixes bug 19905; bugfix on 0.2.7.3-rc; patch by teor.

    o Minor bugfixes (Linux seccomp2 sandbox):
      - Add permission to run the sched_yield() and sigaltstack() system
        calls, in order to support versions of Tor compiled with asan or
        ubsan code that use these calls. Now "sandbox 1" and
        "--enable-expensive-hardening" should be compatible on more
        systems. Fixes bug 20063; bugfix on 0.2.5.1-alpha.

    o Minor bugfixes (logging):
      - Downgrade a harmless log message about the
        pending_entry_connections list from "warn" to "info". Mitigates
        bug 19926.
      - Log a more accurate message when we fail to dump a microdescriptor.
        Fixes bug 17758; bugfix on 0.2.2.8-alpha. Patch from Daniel Pinto.
      - When logging a directory ownership mismatch, log the owning
        username correctly. Fixes bug 19578; bugfix on 0.2.2.29-beta.
      - When we are unable to remove the bw_accounting file, do not warn
        if the reason we couldn't remove it was that it didn't exist.
        Fixes bug 19964; bugfix on 0.2.5.4-alpha. Patch from pastly.

    o Minor bugfixes (memory leak):
      - Fix a series of slow memory leaks related to parsing torrc files
        and options. Fixes bug 19466; bugfix on 0.2.1.6-alpha.
      - Avoid a small memory leak when informing worker threads about
        rotated onion keys. Fixes bug 20401; bugfix on 0.2.6.3-alpha.
      - Fix a small memory leak when receiving AF_UNIX connections on a
        SocksPort. Fixes bug 20716; bugfix on 0.2.6.3-alpha.
      - When moving a signed descriptor object from a source to an
        existing destination, free the allocated memory inside that
        destination object. Fixes bug 20715; bugfix on 0.2.8.3-alpha.
      - Fix a memory leak and use-after-free error when removing entries
        from the sandbox's getaddrinfo() cache. Fixes bug 20710; bugfix on
        0.2.5.5-alpha. Patch from "cypherpunks".
      - Fix a small, uncommon memory leak that could occur when reading a
        truncated ed25519 key file. Fixes bug 18956; bugfix
        on 0.2.6.1-alpha.

    o Minor bugfixes (option parsing):
      - Count unix sockets when counting client listeners (SOCKS, Trans,
        NATD, and DNS). This has no user-visible behavior changes: these
        options are set once, and never read. Required for correct
        behavior in ticket 17178. Fixes bug 19677; bugfix on
        0.2.6.3-alpha. Patch by teor.

    o Minor bugfixes (options):
      - Check the consistency of UseEntryGuards and EntryNodes more
        reliably. Fixes bug 20074; bugfix on 0.2.4.12-alpha. Patch
        by teor.
      - Stop changing the configured value of UseEntryGuards on
        authorities and Tor2web clients. Fixes bug 20074; bugfix on
        commits 51fc6799 in 0.1.1.16-rc and acda1735 in 0.2.4.3-alpha.
        Patch by teor.

    o Minor bugfixes (relay):
      - Ensure relays don't make multiple connections during bootstrap.
        Fixes bug 20591; bugfix on 0.2.8.1-alpha.
      - Do not try to parallelize workers more than 16x without the user
        explicitly configuring us to do so, even if we do detect more than
        16 CPU cores. Fixes bug 19968; bugfix on 0.2.3.1-alpha.

    o Minor bugfixes (testing):
      - The test-stem and test-network makefile targets now depend only on
        the tor binary that they are testing. Previously, they depended on
        "make all". Fixes bug 18240; bugfix on 0.2.8.2-alpha. Based on a
        patch from "cypherpunks".
      - Allow clients to retry HSDirs much faster in test networks. Fixes
        bug 19702; bugfix on 0.2.7.1-alpha. Patch by teor.
      - Avoid a unit test failure on systems with over 16 detectable CPU
        cores. Fixes bug 19968; bugfix on 0.2.3.1-alpha.
      - Let backtrace tests work correctly under AddressSanitizer:
        disable ASAN's detection of segmentation faults while running
        test_bt.sh, so that we can make sure that our own backtrace
        generation code works. Fixes bug 18934; bugfix
        on 0.2.5.2-alpha. Patch from "cypherpunks".
      - Fix the test-network-all target on out-of-tree builds by using the
        correct path to the test driver script. Fixes bug 19421; bugfix
        on 0.2.7.3-rc.
      - Stop spurious failures in the local interface address discovery
        unit tests. Fixes bug 20634; bugfix on 0.2.8.1-alpha; patch by
        Neel Chauhan.
      - Use ECDHE ciphers instead of ECDH in tortls tests. LibreSSL has
        removed the ECDH ciphers which caused the tests to fail on
        platforms which use it. Fixes bug 20460; bugfix on 0.2.8.1-alpha.
      - The tor_tls_server_info_callback unit test no longer crashes when
        debug-level logging is turned on. Fixes bug 20041; bugfix
        on 0.2.8.1-alpha.

    o Minor bugfixes (time):
      - Improve overflow checks in tv_udiff and tv_mdiff. Fixes bug 19483;
        bugfix on all released tor versions.
      - When computing the difference between two times in milliseconds,
        we now round to the nearest millisecond correctly. Previously, we
        could sometimes round in the wrong direction. Fixes bug 19428;
        bugfix on 0.2.2.2-alpha.

    o Minor bugfixes (Tor2web):
      - Prevent Tor2web clients from running hidden services: these services
        are not anonymous due to the one-hop client paths. Fixes bug
        19678. Patch by teor.

    o Minor bugfixes (user interface):
      - Display a more accurate number of suppressed messages in the log
        rate-limiter. Previously, there was a potential integer overflow
        in the counter. Now, if the number of messages hits a maximum, the
        rate-limiter doesn't count any further. Fixes bug 19435; bugfix
        on 0.2.4.11-alpha.
      - Fix a typo in the passphrase prompt for the ed25519 identity key.
        Fixes bug 19503; bugfix on 0.2.7.2-alpha.

    o Code simplification and refactoring:
      - Remove redundant declarations of the MIN macro. Closes
        ticket 18889.
      - Rename tor_dup_addr() to tor_addr_to_str_dup() to avoid confusion.
        Closes ticket 18462; patch from "icanhasaccount".
      - Split the 600-line directory_handle_command_get function into
        separate functions for different URL types. Closes ticket 16698.

    o Documentation:
      - Add module-level internal documentation for 36 C files that
        previously didn't have a high-level overview. Closes ticket 20385.
      - Correct the IPv6 syntax in our documentation for the
        VirtualAddrNetworkIPv6 torrc option. Closes ticket 19743.
      - Correct the minimum bandwidth value in torrc.sample, and queue a
        corresponding change for torrc.minimal. Closes ticket 20085.
      - Fix spelling of "--enable-tor2web-mode" in the manpage. Closes
        ticket 19153. Patch from "U+039b".
      - Module-level documentation for several more modules. Closes
        tickets 19287 and 19290.
      - Document the --passphrase-fd option in the tor manpage. Fixes bug
        19504; bugfix on 0.2.7.3-rc.
      - Document the default PathsNeededToBuildCircuits value that's used
        by clients when the directory authorities don't set
        min_paths_for_circs_pct. Fixes bug 20117; bugfix on 0.2.4.10-alpha.
        Patch by teor, reported by Jesse V.
      - Fix manual for the User option: it takes a username, not a UID.
        Fixes bug 19122; bugfix on 0.0.2pre16 (the first version to have
        a manpage!).
      - Fix the description of the --passphrase-fd option in the
        tor-gencert manpage. The option is used to pass the number of a
        file descriptor to read the passphrase from, not to read the file
        descriptor from. Fixes bug 19505; bugfix on 0.2.0.20-alpha.

    o Removed code:
      - We no longer include the (dead, deprecated) bufferevent code in
        Tor. Closes ticket 19450. Based on a patch from "U+039b".

    o Removed features:
      - Remove support for "GET /tor/bytes.txt" DirPort request, and
        "GETINFO dir-usage" controller request, which were only available
        via a compile-time option in Tor anyway. Feature was added in
        0.2.2.1-alpha. Resolves ticket 19035.
      - There is no longer a compile-time option to disable support for
        TransPort. (If you don't want TransPort, just don't use it.) Patch
        from "U+039b". Closes ticket 19449.

    o Testing:
      - Run more workqueue tests as part of "make check". These had
        previously been implemented, but you needed to know special
        command-line options to enable them.
      - We now have unit tests for our code to reject zlib "compression
        bombs". (Fortunately, the code works fine.)

   Log Message:
   Updated tor to 0.2.9.9.

   Changes in version 0.2.9.9 - 2017-01-23
    Tor 0.2.9.9 fixes a denial-of-service bug where an attacker could
    cause relays and clients to crash, even if they were not built with
    the --enable-expensive-hardening option. This bug affects all 0.2.9.x
    versions, and also affects 0.3.0.1-alpha: all relays running an affected
    version should upgrade.

    This release also resolves a client-side onion service reachability
    bug, and resolves a pair of small portability issues.

    o Major bugfixes (security):
      - Downgrade the "-ftrapv" option from "always on" to "only on when
        --enable-expensive-hardening is provided." This hardening option,
        like others, can turn survivable bugs into crashes -- and having
        it on by default made a (relatively harmless) integer overflow bug
        into a denial-of-service bug. Fixes bug 21278 (TROVE-2017-001);
        bugfix on 0.2.9.1-alpha.

    o Major bugfixes (client, onion service):
      - Fix a client-side onion service reachability bug, where multiple
        socks requests to an onion service (or a single slow request)
        could cause us to mistakenly mark some of the service's
        introduction points as failed, and we cache that failure so
        eventually we run out and can't reach the service. Also resolves a
        mysterious "Remote server sent bogus reason code 65021" log
        warning. The bug was introduced in ticket 17218, where we tried to
        remember the circuit end reason as a uint16_t, which mangled
        negative values. Partially fixes bug 21056 and fixes bug 20307;
        bugfix on 0.2.8.1-alpha.

    o Minor features (geoip):
      - Update geoip and geoip6 to the January 4 2017 Maxmind GeoLite2
        Country database.

    o Minor bugfixes (portability):
      - Avoid crashing when Tor is built using headers that contain
        CLOCK_MONOTONIC_COARSE, but then tries to run on an older kernel
        without CLOCK_MONOTONIC_COARSE. Fixes bug 21035; bugfix
        on 0.2.9.1-alpha.
      - Fix Libevent detection on platforms without Libevent 1 headers
        installed. Fixes bug 21051; bugfix on 0.2.9.1-alpha.
