Changes in version 0.4.5.1-alpha - 2020-10-30
- Tor 0.4.5.1-alpha is the first alpha release in the 0.4.5.x series.
- It improves support for IPv6, address discovery and self-testing, code
+ Tor 0.4.5.1-alpha is the first alpha release in the 0.4.5.x series. It
+ improves support for IPv6, address discovery and self-testing, code
metrics and tracing.
Here are the changes since 0.4.4.5.
- o Major features (IPv6, relay):
- - The torrc option Address now supports IPv6. By doing so, we've also
- unified the interface to find our address to support IPv4, IPv6 and
- hostname. Closes ticket 33233.
-
- o Major features (relay, IPv6):
- - Relays now automatically bind on IPv6 for their ORPort unless specified
- otherwise with the IPv4Only flag. Closes ticket 33246.
-
- o Major features (tracing):
- - Add a tracing library with USDT and LTTng-UST support. Few tracepoints
- were added in the circuit subsystem. More will come incrementally. This
- feature is compiled out by default. It needs to be enabled at configure
- time. See documentation in doc/HACKING/Tracing.md. Closes ticket 32910.
+ - The "optimistic data" feature is now always on; there is no longer
+ an option to disable it from the torrc file or from the consensus
+ directory. Closes part of 40139. - The "usecreatefast" network
+ parameter is now removed; there is no longer an option for authorities
+ to turn it off. Closes part of 40139.
o Major features (IPv6, relay):
- - Launch IPv4 and IPv6 ORPort self-test circuits on relays and bridges.
- Closes ticket 33222.
+ - The torrc option Address now supports IPv6. By doing so, we've
+ also unified the interface to find our address to support IPv4,
+ IPv6 and hostname. Closes ticket 33233.
+ - Launch IPv4 and IPv6 ORPort self-test circuits on relays and
+ bridges. Closes ticket 33222.
o Major features (metrics):
- - Introduce a new MetricsPort which exposes, through an HTTP GET /metrics, a
- series of metrics that tor collects at runtime. At the moment, the only
- supported output format is Prometheus data model. Closes ticket 40063;

o Major features (relay self-testing, IPv6):
- - Relays now track their IPv6 ORPort separately from the reachability of
- their IPv4 ORPort. They will not publish a descriptor unless _both_
- ports appear to be externally reachable. Closes ticket 34067.

+ - Relays now automatically bind on IPv6 for their ORPort unless
+ specified otherwise with the IPv4Only flag. Closes ticket 33246.
- When a relay with IPv6 support opens a connection to another
relay, and the extend cell lists both IPv4 and IPv6 addresses, the
- first relay now picks randomly which address to use. Closes
+ first relay now picks randomly which address to use. Closes

+ incrementally. This feature is compiled out by default. It needs
+ to be enabled at configure time. See documentation in
+ doc/HACKING/Tracing.md. Closes ticket 32910.
+
o Major bugfix (TLS, buffer):
- - When attempting to read N bytes on a TLS connection, really try to read
- those N bytes. Before that, Tor would stop reading after the first TLS
- record which can be smaller than N bytes even though more data was waiting
- on the TLS connection socket. The remaining data would have been read at
- the next mainloop event. Fixes bug 40006; bugfix on 0.1.0.5-rc.

o Minor features (address discovery):
- - If no Address statements are found, relays now prioritize guessing their
- address by looking at the local interface instead of the local hostname.
- If the interface address can't be found, the local hostname is used.
- Closes ticket 33238.
-
- o Minor features (configuration):
- - Allow the using wildcards (* and ?) with the %include option on
- configuration files. Closes ticket 25140. Patch by Daniel Pinto.
- - Allows configuration options EntryNodes, ExcludeNodes,
- ExcludeExitNodes, ExitNodes, MiddleNodes, HSLayer2Nodes and
- HSLayer3Nodes to be specified multiple times. Closes ticket
- 28361. Patch by Daniel Pinto.
-
- o Minor features (control port):
- - Add a DROPTIMEOUTS control port command to drop circuit build timeout
- history and reset the timeout. Closes ticket 40002.
-
- o Minor features (directory authorities):
- - Create new consensus method that removes the unecessary = padding
- from ntor-onion-key. Closes ticket 7869. Patch by Daniel Pinto.

o Minor features (authorities):
- Authorities now list a different set of protocols as required and
- recommended. These lists are chosen so that only truly recommended
- and/or required protocols are included, and so that clients using 0.2.9
- or later will continue to work (even though they are not supported),

o Minor features (bootstrap reporting):
- When reporting bootstrapping status on a relay, do not consider
connections that have never been the target of an origin circuit.
Previously, all connection failures were treated as potential
- bootstrapping failures, including those that had been opened because of
- client requests. Closes ticket 25061.

+ because of client requests. Closes ticket 25061.
o Minor features (build):
- - If the configure script has given any warnings, remind the user about
- them at the end of the script. Related to 40138.
- - When running the configure script, try to detect version mismatches
- between the openssl headers and libraries, and suggest that the
- user should try "--with-openssl-dir". Closes 40138.

static library. This may help with embedding Tor in other
- programs. Note that most Tor functions do not constitute a
- part of a stable or supported API: Only those functions in

Patch by Neel Chauhan.
o Minor features (control port, relay):
- - Introduce "GETINFO address/v4" and "GETINFO address/v6" in the control
- port to fetch the Tor host's respective IPv4 or IPv6 address. We keep

- - When receiving an incoming circuit, only accept it as evidence that we
- are reachable if the declared address of its channel is the same
- address we think that we have. Otherwise, it could be evidence that
- we're reachable on some other address. Fixes bug 20165; bugfix on
- 0.1.0.1-rc.

o Minor bugfixes (SOCKS, onion services):
- - Make sure we send the SOCKS request address in relay begin cells when a
- stream is attached with the purpose CIRCUIT_PURPOSE_CONTROLLER. Fixes bug

o Minor bugfixes (string handling):
- - In summarize_protover_flags(), treat empty strings the same as NULL.
- This prevents protocols_known from being set. Previously, we treated
- empty strings as normal strings, which led to protocols_known being
- set. Fixes bug 34232; bugfix on 0.3.3.2-alpha. Patch by Neel Chauhan.

o Minor bugfixes (v2 onion services):
- - For HSFETCH commands on v2 onion services addresses, check the length of
- bytes decoded, not the base32 length. This takes the behavior introduced
- in commit a517daa56f5848d25ba79617a1a7b82ed2b0a7c0 into consideration.
- Fixes bug 34400; bugfix on 0.4.1.1-alpha. Patch by Neel Chauhan.

- o Code simplification and refactoring (autoconf):
- - Remove autoconf checks for unused funcs and headers. Closes ticket
- 31699; Patch by @bduszel
-
- o Code simplification and refactoring (maintainer scripts):
- - Disable by default the pre-commit hook. Use the environment variable
- TOR_EXTRA_PRE_COMMIT_CHECKS in order to run it. Furthermore, stop running
- practracker in the pre-commit hook and make check-local. Closes ticket
- 40019.
-
- o Code simplification and refactoring (relay address):
- - Most of IPv4 representation was using "uint32_t". It has now been moved to
- use the internal "tor_addr_t" interface instead. This is so we can
- properly integrate IPv6 along IPv4 with common interfaces. Closes ticket

o Code simplification and refactoring:
- Add and use a set of functions to perform downcasts on constant
connection and channel pointers. Closes ticket 40046.
- - Refactor our code that logs a descriptions of connections, channels,
- and the peers on them, to use a single call path. This change
- enables us to refactor the data types that they use, and eliminate
- many confusing users of those types. Closes ticket 40041.

- Refactor some common node selection code into a single function.
Closes ticket 34200.
- - Remove the now-redundant 'outbuf_flushlen' field from our connection
- type. It was previously used for an older version of our rate-limiting
- logic. Closes ticket 33097.
- - Rename "fascist_firewall_*" identifiers to "reachable_addr_*" instead,
- for consistency with other code. Closes ticket 18106.

- Rename functions about "advertised" ports which are not in fact
guaranteed to return the ports have been advertised. Closes
ticket 40055.
- Split implementation of several command line options from
- options_init_from_torrc into smaller isolated functions.
- Patch by Daniel Pinto. Closes ticket 40102.
- - When an extend cell is missing an IPv4 or IPv6 address, fill in the address
- from the extend info. This is similar to what was done in ticket 33633 for
- ed25519 keys. Closes ticket 33816. Patch by Neel Chauhan.

+
+ o Removed features:
+ - We no longer ship or build a "tor.service" file for use with

- option to disable it from the torrc file or from the consensus
- directory.
- Closes part of 40139.
- - The "usecreatefast" network parameter is now removed; there is no
