If you want to see more detailed descriptions of the changes in each development snapshot, see the ChangeLog file. +Changes in version 0.4.2.6 - 2020-01-30 + This is the second stable release in the 0.4.2.x series. It backports + several bugfixes from 0.4.3.1-alpha, including some that had affected + the Linux seccomp2 sandbox or Windows services. If you're running with + one of those configurations, you'll probably want to upgrade; + otherwise, you should be fine with 0.4.2.5. + + o Major bugfixes (linux seccomp sandbox, backport from 0.4.3.1-alpha): + - Correct how we use libseccomp. Particularly, stop assuming that + rules are applied in a particular order or that more rules are + processed after the first match. Neither is the case! In + libseccomp <2.4.0 this lead to some rules having no effect. + libseccomp 2.4.0 changed how rules are generated, leading to a + different ordering, which in turn led to a fatal crash during + startup. Fixes bug 29819; bugfix on 0.2.5.1-alpha. Patch by + Peter Gerber. + - Fix crash when reloading logging configuration while the + experimental sandbox is enabled. Fixes bug 32841; bugfix on + 0.4.1.7. Patch by Peter Gerber. + + o Minor bugfixes (correctness checks, backport from 0.4.3.1-alpha): + - Use GCC/Clang's printf-checking feature to make sure that + tor_assertf() arguments are correctly typed. Fixes bug 32765; + bugfix on 0.4.1.1-alpha. + + o Minor bugfixes (logging, crash, backport from 0.4.3.1-alpha): + - Avoid a possible crash when trying to log a (fatal) assertion + failure about mismatched magic numbers in configuration objects. + Fixes bug 32771; bugfix on 0.4.2.1-alpha. + + o Minor bugfixes (testing, backport from 0.4.3.1-alpha): + - When TOR_DISABLE_PRACTRACKER is set, do not apply it to the + test_practracker.sh script. Doing so caused a test failure. Fixes + bug 32705; bugfix on 0.4.2.1-alpha. + - When TOR_DISABLE_PRACTRACKER is set, log a notice to stderr when + skipping practracker checks. Fixes bug 32705; bugfix + on 0.4.2.1-alpha. + + o Minor bugfixes (windows service, backport from 0.4.3.1-alpha): + - Initialize the publish/subscribe system when running as a windows + service. Fixes bug 32778; bugfix on 0.4.1.1-alpha. + + o Testing (backport from 0.4.3.1-alpha): + - Turn off Tor's Sandbox in Chutney jobs, and run those jobs on + Ubuntu Bionic. Turning off the Sandbox is a work-around, until we + fix the sandbox errors in 32722. Closes ticket 32240. + - Re-enable the Travis CI macOS Chutney build, but don't let it + prevent the Travis job from finishing. (The Travis macOS jobs are + slow, so we don't want to have it delay the whole CI process.) + Closes ticket 32629. + + o Testing (continuous integration, backport from 0.4.3.1-alpha): + - Use zstd in our Travis Linux builds.

The "distinguishing one dynamic web page from another" challenge makes exitmap tricky in the general case, but we can remove that variable here. + +One catch is that Cloudflare currently gives alt-svc headers in response to fetches from Tor addresses. So that means we need a web client that can follow alt-srv headers -- maybe we need a full Selenium like client? + +Once we get the infrastructure set up, we would be smart to run a second one which is just wget or curl or lynx or something, i.e. which doesn't behave like Tor Browser, in order to be able to track the difference between how Cloudflare responds to Tor Browser vs other browsers. + +I imagine that Cloudflare should be internally tracking how they're handling Tor requests, but having a public tracker (a) gives the data to everybody, and (b) helps Cloudflare have a second opinion in case their internal data diverges from the public version. + +The Berkeley ICSI group did research that included this sort of check: +https://www.freehaven.net/anonbib/#differential-ndss2016 +https://www.freehaven.net/anonbib/#exit-blocking2017 +but what I have in mind here is essentially a simpler subset of this research, skipping the complicated part of "how do you tell what kind of response you got" and with an emphasis on automation and consistency. + +There are two interesting metrics to track over time: one is the fraction of exit relays that are getting hit with captchas, and the other is the chance that a Tor client, choosing an exit relay in the normal weighted faction, will get hit by a captcha. + +Then there are other interesting patterns to look for, e.g. "are certain IP addresses punished consistently and others never punished, or is whether you get a captcha much more probabilistic and transient?"

Some come in the form of browser extensions and javascript blockers, others are full fledged web browsers designed with providing extra security to their users. + +One of this is the Tor Browser. The Tor Browser was designed to provide privacy while surfing the web and defend users against both network and local forensic adversaries. There are two main categories of requirements that have been considered: Security Requirements, and Privacy Requirements. + +Security Requirements are the minimum properties in order for a browser to be able to support Tor and similar privacy proxies safely. Privacy requirements are primarily concerned with reducing linkability: the ability for a user's activity on one site to be linked with their activity on another site without their knowledge or explicit consent. + +Websites can work seamsly with the Tor Browser and other privacy enhancing browsers and tools if they adopt a series of respectful and ethical patterns. + +The Tor Browser is in fact, based on Mozilla's Extended Support Release (ESR) Firefox branch. We have a series of patches against this browser to enhance privacy and security. Browser behavior is additionally augmented through the Torbutton extension, and we also change a number of Firefox preferences from their defaults. + +The Tor Project has developed over the years a set of web development guidelines that allow websites to work with security enhanced browsers without causing any or minimal functionality destruption to their users.
