Changes in version 0.4.8.10 - 2023-12-08
This is a security release fixing a high severity bug (TROVE-2023-007)
affecting Exit relays supporting Conflux. We strongly recommend to update as
soon as possible.
o Major bugfixes (TROVE-2023-007, exit):
- Improper error propagation from a safety check in conflux leg
linking lead to a desynchronization of which legs were part of a
conflux set, ultimately causing a UAF and NULL pointer dereference
crash on Exit relays. Fixes bug 40897; bugfix on 0.4.8.1-alpha.
o Minor features (fallbackdir):
- Regenerate fallback directories generated on December 08, 2023.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2023/12/08.
o Minor bugfixes (bridges, statistics):
- Correctly report statistics for client count over Pluggable
transport. Fixes bug 40871; bugfix on 0.4.8.4

Changes in version 0.4.8.9 - 2023-11-09
This is another security release fixing a high severity bug affecting onion
services which is tracked by TROVE-2023-006. We are also releasing a guard
major bugfix as well. If you are an onion service operator, we strongly
recommend to update as soon as possible.
o Major bugfixes (guard usage):
- When Tor excluded a guard due to temporary circuit restrictions,
it considered *additional* primary guards for potential usage by
that circuit. This could result in more than the specified number
of guards (currently 2) being used, long-term, by the tor client.
This could happen when a Guard was also selected as an Exit node,
but it was exacerbated by the Conflux guard restrictions. Both
instances have been fixed. Fixes bug 40876; bugfix
on 0.3.0.1-alpha.
o Major bugfixes (onion service, TROVE-2023-006):
- Fix a possible hard assert on a NULL pointer when recording a
failed rendezvous circuit on the service side for the MetricsPort.
Fixes bug 40883; bugfix on 0.4.8.1-alpha
o Minor features (fallbackdir):
- Regenerate fallback directories generated on November 09, 2023.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2023/11/09.
Changes in version 0.4.8.8 - 2023-11-03
We are releasing today a fix for a high security issue, TROVE-2023-004, that
is affecting relays. Also a few minor bugfixes detailed below. Please upgrade
as soon as posssible.
o Major bugfixes (TROVE-2023-004, relay):
- Mitigate an issue when Tor compiled with OpenSSL can crash during
handshake with a remote relay. Fixes bug 40874; bugfix
on 0.2.7.2-alpha.
o Minor features (fallbackdir):
- Regenerate fallback directories generated on November 03, 2023.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2023/11/03.
o Minor bugfixes (directory authority):
- Look at the network parameter "maxunmeasuredbw" with the correct
spelling. Fixes bug 40869; bugfix on 0.4.6.1-alpha.
o Minor bugfixes (vanguards addon support):
- Count the conflux linked cell as valid when it is successfully
processed. This will quiet a spurious warn in the vanguards addon.
Fixes bug 40878; bugfix on 0.4.8.1-alpha.

retrieved on 2023/09/25.
Changes in version 0.4.8.6 - 2023-09-18
This version contains an important fix for onion service regarding congestion
control and its reliability. Apart from that, uneeded BUG warnings have been
suppressed especially about a compression bomb seen on relays. We strongly
recommend, in particular onion service operators, to upgrade as soon as
possible to this latest stable.
o Major bugfixes (onion service):
- Fix a reliability issue where services were expiring their
introduction points every consensus update. This caused
connectivity issues for clients caching the old descriptor and
intro points. Bug reported and fixed by gitlab user
@hyunsoo.kim676. Fixes bug 40858; bugfix on 0.4.7.5-alpha.

Changes in version 0.4.8.4 - 2023-08-23
Finally, this is the very first stable release of the 0.4.8.x series making,
among other features, Proof-of-Work (prop#327) and Conflux (prop#329)
available to the entire network. Several new features and a lot of bugfixes
detailed below.
o Major feature (denial of service):
- Extend DoS protection to partially opened channels and known relays.
Because re-entry is not allowed anymore, we can apply DoS protections
onto known IP namely relays. Fixes bug 40821; bugfix on 0.3.5.1-alpha.
o Major features (onion service, proof-of-work):
- Implement proposal 327 (Proof-Of-Work). This is aimed at thwarting
introduction flooding DoS attacks by introducing a dynamic Proof-Of-Work
protocol that occurs over introduction circuits. This introduces several
torrc options prefixed with "HiddenServicePoW" in order to control this
feature. By default, this is disabled. Closes ticket 40634.
o Major features (conflux):
- Implement Proposal 329 (conflux traffic splitting). Conflux splits
traffic across two circuits to Exits that support the protocol. These
circuits are pre-built only, which means that if the pre- built conflux
pool runs out, regular circuits will then be used. When using conflux
circuit pairs, clients choose the lower-latency circuit to send data to
the Exit. When the Exit sends data to the client, it maximizes
throughput, by fully utilizing both circuits in a multiplexed fashion.
Alternatively, clients can request that the Exit optimize for latency
when transmitting to them, by setting the torrc option 'ConfluxClientUX
latency'. Onion services are not currently supported, but will be in
arti. Many other future optimizations will also be possible using this
protocol. Closes ticket 40593.
o Major features (dirauth):
- Directory authorities and relays now interact properly with directory
authorities if they change addresses. In the past, they would continue to
upload votes, signatures, descriptors, etc to the hard-coded address in
the configuration. Now, if the directory authority is listed in the
consensus at a different address, they will direct queries to this new
address. Implements ticket 40705.
o Major bugfixes (conflux):
- Fix a relay-side crash caused by side effects of the fix for bug
40827. Reverts part of that fix that caused the crash and adds additional
log messages to help find the root cause. Fixes bug 40834; bugfix on
0.4.8.3-rc.
o Major bugfixes (conflux):
- Fix a relay-side assert crash caused by attempts to use a conflux circuit
between circuit close and free, such that no legs were on the conflux
set. Fixed by nulling out the stream's circuit back- pointer when the
last leg is removed. Additional checks and log messages have been added
to detect other cases. Fixes bug 40827; bugfix on 0.4.8.1-alpha.
o Major bugfixes (proof of work, onion service, hashx):
- Fix a very rare buffer overflow in hashx, specific to the dynamic
compiler on aarch64 platforms. Fixes bug 40833; bugfix on 0.4.8.2-alpha.
o Major bugfixes (vanguards):
- Rotate to a new L2 vanguard whenever an existing one loses the Stable or
Fast flag. Previously, we would leave these relays in the L2 vanguard
list but never use them, and if all of our vanguards end up like this we
wouldn't have any middle nodes left to choose from so we would fail to
make onion-related circuits. Fixes bug 40805; bugfix on 0.4.7.1-alpha.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2023/08/23.
o Minor features (fallbackdir):
- Regenerate fallback directories generated on August 23, 2023.
o Minor features (testing):
- All Rust code is now linted (cargo clippy) as part of GitLab CI, and
existing warnings have been fixed. - Any unit tests written in Rust now
run as part of GitLab CI.
o Minor feature (CI):
- Update CI to use Debian Bullseye for runners.
o Minor feature (client, IPv6):
- Make client able to pick IPv6 relays by default now meaning
ClientUseIPv6 option now defaults to 1. Closes ticket 40785.
o Minor feature (compilation):
- Fix returning something other than "Unknown N/A" as libc version
if we build tor on an O.S. like DragonFlyBSD, FreeBSD, OpenBSD
or NetBSD.
o Minor feature (cpuworker):
- Always use the number of threads for our CPU worker pool to the
number of core available but cap it to a minimum of 2 in case of a
single core. Fixes bug 40713; bugfix on 0.3.5.1-alpha.
o Minor feature (lzma):
- Fix compiler warnings for liblzma >= 5.3.1. Closes ticket 40741.
o Minor feature (MetricsPort, relay):
- Expose time until online keys expires on the MetricsPort. Closes
ticket 40546.
o Minor feature (MetricsPort, relay, onion service):
- Add metrics for the relay side onion service interactions counting
seen cells. Closes ticket 40797. Patch by "friendly73".
o Minor features (directory authorities):
- Directory authorities now include their AuthDirMaxServersPerAddr
config option in the consensus parameter section of their vote.
Now external tools can better predict how they will behave.
Implements ticket 40753.
o Minor features (directory authority):
- Add a new consensus method in which the "published" times on
router entries in a microdesc consensus are all set to a
meaningless fixed date. Doing this will make the download size for
compressed microdesc consensus diffs much smaller. Part of ticket
40130; implements proposal 275.
o Minor features (network documents):
- Clients and relays no longer track the "published on" time
declared for relays in any consensus documents. When reporting
this time on the control port, they instead report a fixed date in
the future. Part of ticket 40130.
o Minor features (fallbackdir):
- Regenerate fallback directories generated on June 01, 2023.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2023/06/01.
o Minor features (hs, metrics):
- Add tor_hs_rend_circ_build_time and tor_hs_intro_circ_build_time
histograms to measure hidden service rend/intro circuit build time
durations. Part of ticket 40757.
o Minor features (metrics):
- Add a `reason` label to the HS error metrics. Closes ticket 40758.
- Add service side metrics for REND and introduction request
failures. Closes ticket 40755.
- Add support for histograms. Part of ticket 40757.
o Minor features (pluggable transports):
- Automatically restart managed Pluggable Transport processes when
their process terminate. Resolves ticket 33669.
o Minor features (portability, compilation):
- Use OpenSSL 1.1 APIs for LibreSSL, fixing LibreSSL 3.5
compatibility. Fixes issue 40630; patch by Alex Xu (Hello71).
o Minor features (relay):
- Do not warn about configuration options that may expose a non-
anonymous onion service. Closes ticket 40691.
o Minor features (relays):
- Trigger OOS when bind fails with EADDRINUSE. This improves
fairness when a large number of exit connections are requested,
and properly signals exhaustion to the network. Fixes issue 40597;
patch by Alex Xu (Hello71).
o Minor features (tests):
- Avoid needless key reinitialization with OpenSSL during unit
tests, saving significant time. Patch from Alex Xu.
o Minor bugfix (hs):
- Fix compiler warnings in equix and hashx when building with clang.
Closes ticket 40800.
o Minor bugfix (FreeBSD, compilation):
- Fix compilation issue on FreeBSD by properly importing
sys/param.h. Fixes bug 40825; bugfix on 0.4.8.1-alpha.
o Minor bugfixes (compression):
- Right after compression/decompression work is done, check for
errors. Before this, we would consider compression bomb before
that and then looking for errors leading to false positive on that
log warning. Fixes bug 40739; bugfix on 0.3.5.1-alpha. Patch
by "cypherpunks".
o Minor bugfixes (compilation):
- Fix all -Werror=enum-int-mismatch warnings. No behavior change.
Fixes bug 40824; bugfix on 0.3.5.1-alpha.
o Minor bugfixes (protocol warn):
- Wrap a handful of cases where ProtocolWarning logs could emit IP
addresses. Fixes bug 40828; bugfix on 0.3.5.1-alpha.
o Minor bugfix (congestion control):
- Reduce the accepted range of a circuit's negotiated 'cc_sendme_inc'
to be +/- 1 from the consensus parameter value. Fixes bug 40569;
bugfix on 0.4.7.4-alpha.
- Remove unused congestion control algorithms and BDP calculation
code, now that we have settled on and fully tuned Vegas. Fixes bug
40566; bugfix on 0.4.7.4-alpha.
- Update default congestion control parameters to match consensus.
Fixes bug 40709; bugfix on 0.4.7.4-alpha.
o Minor bugfixes (compilation):
- Fix "initializer is not a constant" compilation error that
manifests itself on gcc versions < 8.1 and MSVC. Fixes bug 40773;
bugfix on 0.4.8.1-alpha
o Minor bugfixes (conflux):
- Count leg launch attempts prior to attempting to launch them. This
avoids inifinite launch attempts due to internal circuit building
failures. Additionally, double-check that we have enough exits in
our consensus overall, before attempting to launch conflux sets.
Fixes bug 40811; bugfix on 0.4.8.1-alpha.
- Fix a case where we were resuming reading on edge connections that
were already marked for close. Fixes bug 40801; bugfix
on 0.4.8.1-alpha.
- Fix stream attachment order when creating conflux circuits, so
that stream attachment happens after finishing the full link
handshake, rather than upon set finalization. Fixes bug 40801;
bugfix on 0.4.8.1-alpha.
- Handle legs being closed or destroyed before computing an RTT
(resulting in warns about too many legs). Fixes bug 40810; bugfix
on 0.4.8.1-alpha.
- Remove a "BUG" warning from conflux_pick_first_leg that can be
triggered by broken or malicious clients. Fixes bug 40801; bugfix
on 0.4.8.1-alpha.
o Minor bugfixes (KIST):
- Prevent KISTSchedRunInterval from having values of 0 or 1, neither
of which work properly. Additionally, make a separate
KISTSchedRunIntervalClient parameter, so that the client and relay
KIST values can be set separately. Set the default of both to 2ms.
Fixes bug 40808; bugfix on 0.3.2.1-alpha.
o Minor bugfix (relay, logging):
- The wrong max queue cell size was used in a protocol warning
logging statement. Fixes bug 40745; bugfix on 0.4.7.1-alpha.
o Minor bugfixes (logging):
- Avoid ""double-quoting"" strings in several log messages. Fixes
bug 22723; bugfix on 0.1.2.2-alpha.
- Correct a log message when cleaning microdescriptors. Fixes bug
40619; bugfix on 0.2.5.4-alpha.
o Minor bugfixes (metrics):
- Decrement hs_intro_established_count on introduction circuit
close. Fixes bug 40751; bugfix on 0.4.7.12.
o Minor bugfixes (pluggable transports, windows):
- Remove a warning `BUG()` that could occur when attempting to
execute a non-existing pluggable transport on Windows. Fixes bug
40596; bugfix on 0.4.0.1-alpha.
o Minor bugfixes (relay):
- Remove a "BUG" warning for an acceptable race between a circuit
close and considering that circuit active. Fixes bug 40647; bugfix
on 0.3.5.1-alpha.
- Remove a harmless "Bug" log message that can happen in
relay_addr_learn_from_dirauth() on relays during startup. Finishes
fixing bug 40231. Fixes bug 40523; bugfix on 0.4.5.4-rc.
o Minor bugfixes (sandbox):
- Allow membarrier for the sandbox. And allow rt_sigprocmask when
compiled with LTTng. Fixes bug 40799; bugfix on 0.3.5.1-alpha.
- Fix sandbox support on AArch64 systems. More "*at" variants of
syscalls are now supported. Signed 32 bit syscall parameters are
checked more precisely, which should lead to lower likelihood of
breakages with future compiler and libc releases. Fixes bug 40599;
bugfix on 0.4.4.3-alpha.
o Minor bugfixes (state file):
- Avoid a segfault if the state file doesn't contains TotalBuildTimes
along CircuitBuildAbandonedCount being above 0. Fixes bug 40437;
bugfix on 0.3.5.1-alpha.
o Removed features:
- Remove the RendPostPeriod option. This was primarily used in
Version 2 Onion Services and after its deprecation isn't needed
anymore. Closes ticket 40431. Patch by Neel Chauhan.

Changes in version 0.4.7.13 - 2023-01-12
This version contains three major bugfixes, two for relays and one for
client being a security fix, TROVE-2022-002. We have added, for Linux, the
support for IP_BIND_ADDRESS_NO_PORT for relays using OutboundBindAddress.
We strongly recommend to upgrade to this version considering the important
congestion control fix detailed below.
o Major bugfixes (congestion control):
- Avoid incrementing the congestion window when the window is not
fully in use. Thia prevents overshoot in cases where long periods
of low activity would allow our congestion window to grow, and
then get followed by a burst, which would cause queue overload.
Also improve the increment checks for RFC3742. Fixes bug 40732;
bugfix on 0.4.7.5-alpha.
o Major bugfixes (relay):
- When opening a channel because of a circuit request that did not
include an Ed25519 identity, record the Ed25519 identity that we
actually received, so that we can use the channel for other
circuit requests that _do_ list an Ed25519 identity. (Previously
we had code to record this identity, but a logic bug caused it to
be disabled.) Fixes bug 40563; bugfix on 0.3.0.1-alpha. Patch
from "cypherpunks".
o Major bugfixes (TROVE-2022-002, client):
- The SafeSocks option had its logic inverted for SOCKS4 and
SOCKS4a. It would let the unsafe SOCKS4 pass but not the safe
SOCKS4a one. This is TROVE-2022-002 which was reported on
Hackerone by "cojabo". Fixes bug 40730; bugfix on 0.3.5.1-alpha.
o Minor feature (authority):
- Reject 0.4.6.x series at the authority level. Closes ticket 40664.
o Minor features (fallbackdir):
- Regenerate fallback directories generated on January 12, 2023.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2023/01/12.
o Minor features (relays):
- Set the Linux-specific IP_BIND_ADDRESS_NO_PORT option on outgoing
sockets, allowing relays using OutboundBindAddress to make more
outgoing connections than ephemeral ports, as long as they are to
separate destinations. Related to issue 40597; patch by Alex
Xu (Hello71).
o Minor bugfixes (relay, metrics):
- Fix typo in a congestion control label on the MetricsPort. Fixes
bug 40727; bugfix on 0.4.7.12.
o Minor bugfixes (sandbox, authority):
- With the sandbox enabled, allow to write "my-consensus-
{ns|microdesc}" and to rename them as well. Fixes bug 40729;
bugfix on 0.3.5.1-alpha.
o Code simplifications and refactoring:
- Rely on actual error returned by the kernel when choosing what
resource exhaustion to log. Fixes issue 40613; Fix
on tor-0.4.6.1-alpha.

Changes in version 0.4.7.12 - 2022-12-06
This version contains a major change that is a new key for moria1. Also, new
metrics are exported on the MetricsPort for the congestion control
subsystem.
o Directory authority changes (moria1):
- Rotate the relay identity key and v3 identity key for moria1. They
have been online for more than a decade and refreshing keys
periodically is good practice. Advertise new ports too, to avoid
confusion. Closes ticket 40722.
o Minor feature (Congestion control metrics):

Changes in version 0.4.7.10 - 2022-08-12
This version updates the geoip cache that we generate from IPFire location
database to use the August 9th, 2022 one. Everyone MUST update to this
latest release else circuit path selection and relay metrics are badly
affected.
o Major bugfixes (geoip data):
- IPFire informed us on August 12th that databases generated after
(including) August 10th did not have proper ARIN network allocations. We
are updating the database to use the one generated on August 9th, 2022.
Fixes bug 40658; bugfix on 0.4.7.9.
Changes in version 0.4.7.9 - 2022-08-11
This version contains several major fixes aimed at reducing memory pressure on
relays and possible side-channel. It also contains a major bugfix related to
congestion control also aimed at reducing memory pressure on relays.
Finally, there is last one major bugfix related to Vanguard L2 layer node
selection.
We strongly recommend to upgrade to this version especially for Exit relays
in order to help the network defend against this ongoing DDoS.
o Major bugfixes (congestion control):
- Implement RFC3742 Limited Slow Start. Congestion control was
overshooting the congestion window during slow start, particularly
for onion service activity. With this fix, we now update the
congestion window more often during slow start, as well as dampen
the exponential growth when the congestion window grows above a
capping parameter. This should reduce the memory increases guard
relays were seeing, as well as allow us to set lower queue limits
to defend against ongoing DoS attacks. Fixes bug 40642; bugfix
on 0.4.7.5-alpha.
o Major bugfixes (relay):
- Remove OR connections btrack subsystem entries when the connections
close normally. Before this, we would only remove the entry on error and
thus leaking memory for each normal OR connections. Fixes bug 40604;
bugfix on 0.4.0.1-alpha.
- Stop sending TRUNCATED cell and instead close the circuit from which we
received a DESTROY cell. This makes every relay in the circuit path to
stop queuing cells. Fixes bug 40623; bugfix on 0.1.0.2-rc.
o Major bugfixes (vanguards):
- We had omitted some checks for whether our vanguards (second layer
guards from proposal 333) overlapped. Now make sure to pick each
of them to be independent. Also, change the design to allow them
to come from the same family. Fixes bug 40639; bugfix
on 0.4.7.1-alpha.
o Minor features (dirauth):
- Add a torrc option to control the Guard flag bandwidth threshold
percentile. Closes ticket 40652.
- Add an AuthDirVoteGuard torrc option that can allow authorities to
assign the Guard flag to the given fingerprints/country code/IPs.
This is a needed feature mostly for defense purposes in case a DoS
hits the network and relay start losing the Guard flags too fast.
- Make UPTIME_TO_GUARANTEE_STABLE, MTBF_TO_GUARANTEE_STABLE,
TIME_KNOWN_TO_GUARANTEE_FAMILIAR WFU_TO_GUARANTEE_GUARD tunable
from torrc.
o Minor features (fallbackdir):
- Regenerate fallback directories generated on August 11, 2022.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2022/08/11.
o Minor bugfixes (congestion control):
- Add a check for an integer underflow condition that might happen
in cases where the system clock is stopped, the ORconn is blocked,
and the endpoint sends more than a congestion window worth of non-
data control cells at once. This would cause a large congestion
window to be calculated instead of a small one. No security
impact. Fixes bug 40644; bugfix on 0.4.7.5-alpha.
o Minor bugfixes (defense in depth):
- Change a test in the netflow padding code to make it more
_obviously_ safe against remotely triggered crashes. (It was safe
against these before, but not obviously so.) Fixes bug 40645;
bugfix on 0.3.1.1-alpha.
o Minor bugfixes (relay):
- Do not propagate either forward or backward a DESTROY remote reason when
closing a circuit in order to avoid a possible side channel. Fixes bug
40649; bugfix on 0.1.2.4-alpha.

Changes in version 0.4.7.8 - 2022-06-17
This version fixes several bugfixes including a High severity security issue
categorized as a Denial of Service. Everyone running an earlier version
should upgrade to this version.
o Major bugfixes (congestion control, TROVE-2022-001):
- Fix a scenario where RTT estimation can become wedged, seriously
degrading congestion control performance on all circuits. This
impacts clients, onion services, and relays, and can be triggered
remotely by a malicious endpoint. Tracked as CVE-2022-33903. Fixes
bug 40626; bugfix on 0.4.7.5-alpha.
o Minor features (fallbackdir):
- Regenerate fallback directories generated on June 17, 2022.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2022/06/17.
o Minor bugfixes (linux seccomp2 sandbox):
- Allow the rseq system call in the sandbox. This solves a crash
issue with glibc 2.35 on Linux. Patch from pmu-ipf. Fixes bug
40601; bugfix on 0.3.5.11.
o Minor bugfixes (logging):
- Demote a harmless warn log message about finding a second hop to
from warn level to info level, if we do not have enough
descriptors yet. Leave it at notice level for other cases. Fixes
bug 40603; bugfix on 0.4.7.1-alpha.
- Demote a notice log message about "Unexpected path length" to info
level. These cases seem to happen arbitrarily, and we likely will
never find all of them before the switch to arti. Fixes bug 40612;
bugfix on 0.4.7.5-alpha.
o Minor bugfixes (relay, logging):
- Demote a harmless XOFF log message to from notice level to info
level. Fixes bug 40620; bugfix on 0.4.7.5-alpha.

Historically, the MD5 checksums in our LFS files serve as a protection
against broken downloads, or accidentally corrupted source files.
While the sources are nowadays downloaded via HTTPS, it make sense to
beef up integrity protection for them, since transparently intercepting
TLS is believed to be feasible for more powerful actors, and the state
of the public PKI ecosystem is clearly not helping.
Therefore, this patch switches from MD5 to BLAKE2, updating all LFS
files as well as make.sh to deal with this checksum algorithm. BLAKE2 is
notably faster (and more secure) than SHA2, so the performance penalty
introduced by this patch is negligible, if noticeable at all.
In preparation of this patch, the toolchain files currently used have
been supplied with BLAKE2 checksums as well on
https://source.ipfire.org/.

Changes in version 0.4.6.9 - 2021-12-15
This version fixes several bugs from earlier versions of Tor. One important
piece is the removal of DNS timeout metric from the overload general signal.
See below for more details.
o Major bugfixes (relay, overload):
- Don't make Tor DNS timeout trigger an overload general state.
These timeouts are different from DNS server timeout. They have to
be seen as timeout related to UX and not because of a network
problem. Fixes bug 40527; bugfix on 0.4.6.1-alpha.
o Minor feature (reproducible build):
- The repository can now build reproducible tarballs which adds the
build command "make dist-reprod" for that purpose. Closes
ticket 26299.
o Minor features (compilation):
- Give an error message if trying to build with a version of
LibreSSL known not to work with Tor. (There's an incompatibility
with LibreSSL versions 3.2.1 through 3.4.0 inclusive because of
their incompatibility with OpenSSL 1.1.1's TLSv1.3 APIs.) Closes
ticket 40511.
o Minor features (fallbackdir):
- Regenerate fallback directories generated on December 15, 2021.
o Minor features (geoip data):
- Update the geoip files to match the IPFire Location Database, as
retrieved on 2021/12/15.
o Minor bugfixes (compilation):
- Fix our configuration logic to detect whether we had OpenSSL 3:
previously, our logic was reversed. This has no other effect than
to change whether we suppress deprecated API warnings. Fixes bug
40429; bugfix on 0.3.5.13.
o Minor bugfixes (relay):
- Reject IPv6-only DirPorts. Our reachability self-test forces
DirPorts to be IPv4, but our configuration parser allowed them to
be IPv6-only, which led to an assertion failure. Fixes bug 40494;
bugfix on 0.4.5.1-alpha.
o Documentation (man, relay):
- Missing "OverloadStatistics" in tor.1 manpage. Fixes bug 40504;
bugfix on 0.4.6.1-alpha.

Changes in version 0.4.6.8 - 2021-10-26
This version fixes several bugs from earlier versions of Tor. One
highlight is a fix on how we track DNS timeouts to report general
relay overload.
o Major bugfixes (relay, overload state):
- Relays report the general overload state for DNS timeout errors
only if X% of all DNS queries over Y seconds are errors. Before
that, it only took 1 timeout to report the overload state which
was just too low of a threshold. The X and Y values are 1% and 10
minutes respectively but they are also controlled by consensus
parameters. Fixes bug 40491; bugfix on 0.4.6.1-alpha.
o Minor features (fallbackdir):
- Regenerate fallback directories for October 2021. Closes
ticket 40493.
o Minor features (testing):
- On a testing network, relays can now use the
TestingMinTimeToReportBandwidth option to change the smallest
amount of time over which they're willing to report their observed
maximum bandwidth. Previously, this was fixed at 1 day. For
safety, values under 2 hours are only supported on testing
networks. Part of a fix for ticket 40337.
- Relays on testing networks no longer rate-limit how frequently
they are willing to report new bandwidth measurements. Part of a
fix for ticket 40337.
- Relays on testing networks now report their observed bandwidths
immediately from startup. Previously, they waited until they had
been running for a full day. Closes ticket 40337.
o Minor bugfix (onion service):
- Do not flag an HSDir as non-running in case the descriptor upload
or fetch fails. An onion service closes pending directory
connections before uploading a new descriptor which can thus lead
to wrongly flagging many relays and thus affecting circuit building
path selection. Fixes bug 40434; bugfix on 0.2.0.13-alpha.
- Improve logging when a bad HS version is given. Fixes bug 40476;
bugfix on 0.4.6.1-alpha.
o Minor bugfix (CI, onion service):
- Exclude onion service version 2 Stem tests in our CI. Fixes bug 40500;
bugfix on 0.3.2.1-alpha.
o Minor bugfixes (compatibility):
- Fix compatibility with the most recent Libevent versions, which no
longer have an evdns_set_random_bytes() function. Because this
function has been a no-op since Libevent 2.0.4-alpha, it is safe
for us to just stop calling it. Fixes bug 40371; bugfix
on 0.2.1.7-alpha.
o Minor bugfixes (onion service, TROVE-2021-008):
- Only log v2 access attempts once total, in order to not pollute
the logs with warnings and to avoid recording the times on disk
when v2 access was attempted. Note that the onion address was
_never_ logged. This counts as a Low-severity security issue.
Fixes bug 40474; bugfix on 0.4.5.8.
Since we configure Tor to use libseccomp, the latter has been updated
for kernel 5.15 as well, hence we need to ship Tor either way.

running an earlier version, whether as a client, a relay, or an onion
service, should upgrade to Tor 0.3.5.16, 0.4.5.10, or 0.4.6.7.
o Major bugfixes (cryptography, security):
- Resolve an assertion failure caused by a behavior mismatch between
our batch-signature verification code and our single-signature
verification code. This assertion failure could be triggered
remotely, leading to a denial of service attack. We fix this issue
by disabling batch verification. Fixes bug 40078; bugfix on
0.2.6.1-alpha. This issue is also tracked as TROVE-2021-007 and
CVE-2021-38385. Found by Henry de Valence.

on 0.4.6.2-alpha.
o Minor bugfixes (relay):
- Reduce the compression level for data streaming from HIGH to LOW
in order to reduce CPU load on the directory relays. Fixes bug
40301; bugfix on 0.3.5.1-alpha.
o Minor bugfixes (timekeeping):
- Calculate the time of day correctly on systems where the time_t
type includes leap seconds. (This is not the case on most
operating systems, but on those where it occurs, our tor_timegm
function did not correctly invert the system's gmtime function,
which could result in assertion failures when calculating voting
schedules.) Fixes bug 40383; bugfix on 0.2.0.3-alpha.

Full changelog as per https://gitweb.torproject.org/tor.git/plain/ChangeLog?h=tor-0.4.5.7:
Changes in version 0.4.5.7 - 2021-03-16
Tor 0.4.5.7 fixes two important denial-of-service bugs in earlier
versions of Tor.
One of these vulnerabilities (TROVE-2021-001) would allow an attacker
who can send directory data to a Tor instance to force that Tor
instance to consume huge amounts of CPU. This is easiest to exploit
against authorities, since anybody can upload to them, but directory
caches could also exploit this vulnerability against relays or clients
when they download. The other vulnerability (TROVE-2021-002) only
affects directory authorities, and would allow an attacker to remotely
crash the authority with an assertion failure. Patches have already
been provided to the authority operators, to help ensure
network stability.
We recommend that everybody upgrade to one of the releases that fixes
these issues (0.3.5.14, 0.4.4.8, or 0.4.5.7) as they become available
to you.
This release also updates our GeoIP data source, and fixes a few
smaller bugs in earlier releases.
o Major bugfixes (security, denial of service):
- Disable the dump_desc() function that we used to dump unparseable
information to disk. It was called incorrectly in several places,
in a way that could lead to excessive CPU usage. Fixes bug 40286;
bugfix on 0.2.2.1-alpha. This bug is also tracked as TROVE-2021-
001 and CVE-2021-28089.
- Fix a bug in appending detached signatures to a pending consensus
document that could be used to crash a directory authority. Fixes
bug 40316; bugfix on 0.2.2.6-alpha. Tracked as TROVE-2021-002
and CVE-2021-28090.
o Minor features (geoip data):
- We have switched geoip data sources. Previously we shipped IP-to-
country mappings from Maxmind's GeoLite2, but in 2019 they changed
their licensing terms, so we were unable to update them after that
point. We now ship geoip files based on the IPFire Location
Database instead. (See https://location.ipfire.org/ for more
information). This release updates our geoip files to match the
IPFire Location Database as retrieved on 2021/03/12. Closes
ticket 40224.
o Minor bugfixes (directory authority):
- Now that exit relays don't allow exit connections to directory
authority DirPorts (to prevent network reentry), disable
authorities' reachability self test on the DirPort. Fixes bug
40287; bugfix on 0.4.5.5-rc.
o Minor bugfixes (documentation):
- Fix a formatting error in the documentation for
VirtualAddrNetworkIPv6. Fixes bug 40256; bugfix on 0.2.9.4-alpha.
o Minor bugfixes (Linux, relay):
- Fix a bug in determining total available system memory that would
have been triggered if the format of Linux's /proc/meminfo file
had ever changed to include "MemTotal:" in the middle of a line.
Fixes bug 40315; bugfix on 0.2.5.4-alpha.
o Minor bugfixes (metrics port):
- Fix a BUG() warning on the MetricsPort for an internal missing
handler. Fixes bug 40295; bugfix on 0.4.5.1-alpha.
o Minor bugfixes (onion service):
- Remove a harmless BUG() warning when reloading tor configured with
onion services. Fixes bug 40334; bugfix on 0.4.5.1-alpha.
o Minor bugfixes (portability):
- Fix a non-portable usage of "==" with "test" in the configure
script. Fixes bug 40298; bugfix on 0.4.5.1-alpha.
o Minor bugfixes (relay):
- Remove a spammy log notice falsely claiming that the IPv4/v6
address was missing. Fixes bug 40300; bugfix on 0.4.5.1-alpha.
- Do not query the address cache early in the boot process when
deciding if a relay needs to fetch early directory information
from an authority. This bug resulted in a relay falsely believing
it didn't have an address and thus triggering an authority fetch
at each boot. Related to our fix for 40300.
o Removed features (mallinfo deprecated):
- Remove mallinfo() usage entirely. Libc 2.33+ now deprecates it.
Closes ticket 40309.

https://gitweb.torproject.org/tor.git/plain/ChangeLog?h=tor-0.4.4.7:
Changes in version 0.4.4.7 - 2021-02-03
Tor 0.4.4.7 backports numerous bugfixes from later releases,
including one that made v3 onion services more susceptible to
denial-of-service attacks, and a feature that makes some kinds of
DoS attacks harder to perform.
o Major bugfixes (onion service v3, backport from 0.4.5.3-rc):
- Stop requiring a live consensus for v3 clients and services, and
allow a "reasonably live" consensus instead. This allows v3 onion
services to work even if the authorities fail to generate a
consensus for more than 2 hours in a row. Fixes bug 40237; bugfix
on 0.3.5.1-alpha.
o Major feature (exit, backport from 0.4.5.5-rc):
- Re-entry into the network is now denied at the Exit level to all
relays' ORPorts and authorities' ORPorts and DirPorts. This change
should help mitgate a set of denial-of-service attacks. Closes
ticket 2667.
o Minor feature (build system, backport from 0.4.5.4-rc):
- New "make lsp" command to generate the compile_commands.json file
used by the ccls language server. The "bear" program is needed for
this. Closes ticket 40227.
o Minor features (compilation, backport from 0.4.5.2-rc):
- Disable deprecation warnings when building with OpenSSL 3.0.0 or
later. There are a number of APIs newly deprecated in OpenSSL
3.0.0 that Tor still requires. (A later version of Tor will try to
stop depending on these APIs.) Closes ticket 40165.
o Minor features (crypto, backport from 0.4.5.3-rc):
- Fix undefined behavior on our Keccak library. The bug only
appeared on platforms with 32-byte CPU cache lines (e.g. armv5tel)
and would result in wrong digests. Fixes bug 40210; bugfix on
0.2.8.1-alpha. Thanks to Bernhard Übelacker, Arnd Bergmann and
weasel for diagnosing this.
o Minor bugfixes (compatibility, backport from 0.4.5.1-rc):
- Strip '\r' characters when reading text files on Unix platforms.
This should resolve an issue where a relay operator migrates a
relay from Windows to Unix, but does not change the line ending of
Tor's various state files to match the platform, and the CRLF line
endings from Windows end up leaking into other files such as the
extra-info document. Fixes bug 33781; bugfix on 0.0.9pre5.
o Minor bugfixes (compilation, backport from 0.4.5.3-rc):
- Fix a compilation warning about unreachable fallthrough
annotations when building with "--enable-all-bugs-are-fatal" on
some compilers. Fixes bug 40241; bugfix on 0.3.5.4-alpha.
o Minor bugfixes (SOCKS5, backport from 0.4.5.3-rc):
- Handle partial SOCKS5 messages correctly. Previously, our code
would send an incorrect error message if it got a SOCKS5 request
that wasn't complete. Fixes bug 40190; bugfix on 0.3.5.1-alpha.
o Minor bugfixes (testing, backport from 0.4.5.2-alpha):
- Fix the `config/parse_tcp_proxy_line` test so that it works
correctly on systems where the DNS provider hijacks invalid
queries. Fixes part of bug 40179; bugfix on 0.4.3.1-alpha.
- Fix our Python reference-implementation for the v3 onion service
handshake so that it works correctly with the version of hashlib
provided by Python 3.9. Fixes part of bug 40179; bugfix
on 0.3.1.6-rc.
- Fix the `tortls/openssl/log_one_error` test to work with OpenSSL
3.0.0. Fixes bug 40170; bugfix on 0.2.8.1-alpha.
