Changes in version 0.3.4.1-alpha - 2018-05-1?
XXX BLURB
+ o New system requirements:
+ - Tor no longer tries to support systems without mmap() or some
+ local equivalent. Apparently, compilation on such systems has been
+ broken for some time, without anybody noticing or complaining.
+ Closes ticket 25398.
o Major feature (directory authority, modularization):
- - The directory authority subsystem has been modularized. The code is now
- located in src/or/dirauth/ which is compiled in by default. To disable the
- module, the configure option --disable-module-dirauth has been added.
- Closes ticket 25610;

+ To disable the module, the configure option
+ --disable-module-dirauth has been added. Closes ticket 25610;
o Major feature (main loop, CPU usage):
- - Previously, tor would enable at startup all possible main loop event
- regardless if it needed them. For instance, directory authorities
- callbacks were fired up even for client only. We have now refactored this
- whole interface to only enable the appropriate callbacks depending on what
- are tor roles (client only, relay, hidden service, etc.). Furthermore,
- these events now depend on DisableNetwork or the hibernation state in
- order to enable them. This is a big step towards reducing client CPU usage
- by reducing the amount of wake ups the daemon does. Closes ticket 25376

+ device is sleeping, or Tor is not running. Closes ticket 26063.
o Major features (main loop, CPU wakeup):
- The bandwidth-limitation logic has been refactored so that
- bandwidth calculations are performed on-demand, rather than
- every TokenBucketRefillInterval milliseconds.
- This change should improve the granularity of our bandwidth
- calculations, and limit the number of times that the Tor process needs
- to wake up when it is idle. Closes ticket 25373.

+ number of times that the Tor process needs to wake up when it is

o Major bugfixes (directory authorities, security):
- - When directory authorities read a zero-byte bandwidth file, they log
- a warning with the contents of an uninitialised buffer. Log a warning
- about the empty file instead.
- Fixes bug 26007; bugfix on 0.2.2.1-alpha.

+ - Correctly detect when onion services get disabled after HUP. Fixes
+ bug 25761; bugfix on 0.3.2.1.
o Major bugfixes (protover, voting):
- - Revise Rust implementation of protover to use a more memory-efficient
- voting algorithm and corresponding data structures, thus avoiding a
- potential (but small impact) DoS attack where specially crafted protocol
- strings would expand to several potential megabytes in memory. In the
- process, several portions of code were revised to be methods on new,
- custom types, rather than functions taking interchangeable types, thus
- increasing type safety of the module. Custom error types and handling
- were added as well, in order to facilitate better error dismissal/handling

- module. This should prevent a bug where authentication cookies
- are not generated on restart. Fixes bug 25512; bugfix on 0.3.3.1-alpha.

o Minor bugfixes (test):
- - When testing workqueue event-cancellation, make sure that we actually
- cancel an event, and that cancel each event with equal probability.
- (It was previously possible, though extremely unlikely, for our
- event-canceling test not to cancel any events.) Fixes bug 26008;

o Minor bugfixes (testing):
- - Repeat part of the test in test_client_pick_intro() a number of times,
- to give it consistent coverage. Fixes bug 25996; bugfix on

- - Remove randomness from the hs_common/responsible_hsdirs test,
- so that it always takes the same path through the function it tests.

Fixes bug 25997; bugfix on 0.3.2.1-alpha.
o Minor bugfixes (tests):
- - Change the behavior of the "channel/outbound" test so that it never
- causes a 10-second rollover for the EWMA circuitmux code. Previously,
- this behavior would happen randomly, and result in fluctuating test
- coverage. Fixes bug 25994; bugfix on 0.3.3.1-alpha.

- Use X509_new() to allocate certificates that will be freed later
with X509_free(). Previously, some parts of the unit tests had
- used tor_malloc_zero(), which is incorrect, and which caused
- test failures on Windows when they were built with extra hardening.
- Fixes bugs 25943 and 25944; bugfix on 0.2.8.1-alpha.
- Patch by Marcin CieÅ?lak.
- - While running the circuit_timeout test, fix the PRNG to a deterministic
- AES stream, so that the test coverage from this test will itself be
- deterministic. Fixes bug 25995; bugfix on 0.2.2.2-alpha.

o Minor bugfixes (vanguards):
- - Allow the last hop in a vanguard circuit to be the same as our first,
- to prevent the adversary from influencing guard node choice by choice
- of last hop. Also prevent the creation of A - B - A paths, or A - A
- paths, which are forbidden by relays. Fixes bug 25870; bugfix on

o Code simplification and refactoring:
- We remove the PortForwsrding and PortForwardingHelper options, related
- functions, and the port_forwarding tests. These options were used by
- the now-deprecated Vidalia to help ordinary users become Tor relays or
- bridges. Closes ticket 25409. Patch by Neel Chauhan.

- In order to make the OR and dir checking function in router.c less
- confusing we renamed some functions and consider_testing_reachability()
- has been splitted into router_should_check_reachability() and
- router_do_reachability_checks(). Also we improved the documentation in
- some functions. Closes ticket 18918.
- - Initial work to isolate Libevent usage to a handful of modules in our
- codebase, to simplify our call structure, and so that we can more
- easily change event loops in the future if needed. Closes ticket
- 23750.
- - Introduce a function to call getsockname() and return
- tor_addr_t, to save a little complexity throughout the codebase.

- Make hsdir_index in node_t a hsdir_index_t rather than a pointer
as hsdir_index is always present. Also, we move hsdir_index_t into
or.h. Closes ticket 23094. Patch by Neel Chauhan.

- that do not allocate memory for the output buffer string.
- NODE_DESC_BUF_LEN constant and format_node_description() function
- cannot be used externally from router.c module anymore.

- Our main loop has been simplified so that all important operations
happen inside events. Previously, some operations had to happen
outside the event loop, to prevent infinite sequences of event
activations. Closes ticket 25374.
- - Put a SHA1 public key digest in hs_service_intro_point_t, and use it in
- register_intro_circ() and service_intro_point_new(). This prevents the

- Refactor token-bucket implementations to use a common backend.
Closes ticket 25766.
- - Remove extern declaration of stats_n_seconds_working variable from main,
- protecting its accesses with get_uptime() and reset_uptime() functions.
- Closes ticket 25081, patch by â??valentecaioâ??.
- - Remove our previous logic for "cached gettimeofday()" -- our coarse
- monotonic timers are fast enough for this purpose, and far less
- error-prone. Implements part of ticket 25927.

- Remove the return value for fascist_firewall_choose_address_base(),
and sister functions such as fascist_firewall_choose_address_node()
and fascist_firewall_choose_address_rs(). Also, while we're here,
initialize the ap argument as leaving it uninitialized can pose a
security hazard. Closes ticket 24734. Patch by Neel Chauhan.
- - Rename two fields of connection_t struct.
- timestamp_lastwritten is renamed to timestamp_last_write_allowed and
- timestamp_lastread is renamed to timestamp_last_read_allowed.

- Since Tor requires C99, remove our old workaround code for libc
implementations where free(NULL) doesn't work. Closes ticket 24484.
- - Use our standard rate-limiting code to deal with excessive libevent
- failures, rather than the hand-rolled logic we had before.

- in node_ipv6_or_preferred() and node_ipv6_dir_preferred() in
- order to check for a null address. Closes ticket 23873. Patch

o Deprecated features:
- - As we are not recommending 0.2.5 anymore we require relays that once had
- an ed25519 key associated with their RSA key to always have that key
- instead of allowing them to drop back to a version that didn't support
- ed25519. This means they need to use a new RSA key if the want to
- downgrade to an older version of tor without ed25519. Closes ticket 20522.

o Documentation:
- - Correct an IPv6 error in the documentation for ExitPolicy.
- Closes ticket 25857. Patch from "CTassisF".
-
- o New system requirements:
- - Tor no longer tries to support systems without mmap() or some local
- equivalent. Apparently, compilation on such systems has been broken for
- some time, without anybody noticing or complaining. Closes ticket
- 25398.
+ - Correct an IPv6 error in the documentation for ExitPolicy. Closes
+ ticket 25857. Patch from "CTassisF".
o Removed features:
- - Directory authorities will no longer support voting according to any
- consensus method before consensus method 25. This keeps authorities
- compatible with all authorities running 0.2.9.8 and later, and does
- not break any clients or relays. Implements ticket 24378 and
- proposal 290.

- The PortForwarding and PortForwardingHelper features have been
- removed. The reasoning is, given that implementations of NAT traversal
- protocols within common consumer grade routers are frequently buggy, and
- that the target audience for a NAT punching feature is a perhaps
- less-technically-inclined relay operator, when the helper fails to setup
- traversal the problems are usually deep, ugly, and very router specific,
- making them horrendously impossible for technical support to reliable
- assist with, and thus resulting in frustration all around. Unfortunately,
- relay operators who would like to run relays behind NATs will need to
- become more familiar with the port forwarding configurations on their
- local router. Closes 25409.

- in testing simulations to measure how often connection buckets were
- emptied, in order to improve our scheduling, but it has not

- The old "round-robin" circuit multiplexer (circuitmux)
implementation has been removed, along with a fairly large set of
- code that existed to support it. It has not been the default
+ code that existed to support it. It has not been the default
circuitmux since we introduced the "EWMA" circuitmux in 0.2.4.x,
but it still required an unreasonable amount of memory and CPU.
Closes ticket 25268.
