When you're logged into Twitter, https://twitter.com/ shows you your
stream of tweets. With the current version, a user can't see its own
stream anymore. Can you redirect to the search page only for
non-logged-in users?

[tor-dev] Analysis of ASan usage

2016-02-18 Thread Jens Kubieziel
Hi,

FYI:
oss-security lately had a posting with the title »Address Sanitizer
local root«
(http://www.openwall.com/lists/oss-security/2016/02/17/9>)
The author showed that building a suid binary with ASan enables local
root exploits. He also shows some other problems with this approach.

In his posting he mentions the Tor Browser and recommends to not use the
word »hardened«, because it is misleading.

[tor-dev] Status of remaining SVN repositories

2015-10-27 Thread Jens Kubieziel
Hi,

Tor has a SVN with several repositories in it. The ticket #4929 deals
with migrating them to git
(https://trac.torproject.org/projects/tor/ticket/4929>). I made a
table within the ticket to track the current status. Most of the
repositories are in git right now. However some remain where I don't
know what the current status is. This are:
- blossom
- bsockets
- incognito
- libevent-urz
- topf
- projects (it seems sub repos are in git)
- website

Should the first five repos also be moved to trac or what do we want to
do with them?

Sometimes #tor and #tor-dev get spammed by some individual. During these
times the channel operator sets some protection or bans special
hostnames. If this is the case for you, just wait some time and come
back later. Usually those protections are removed after the spammer is
gone.
As far as I see it both channels have no special flags right now.

[tor-dev] Accessing hidden services with TAP or ntor

2014-02-20 Thread Jens Kubieziel
Hi,

we had some discussions during the dev meeting regarding hidden services
and why users sometimes report that the access to them fails. The
general problem might be that the specific hidden service doesn't exist
anymore. However in some cases the HS exists (see
http://tor.stackexchange.com/q/1442/88> as an example).

So one theory was that the transistion from TAP to ntor might cause
problems. I tried to test it and found no evidence so far.

What did I do? I checked out the current Tor source from git and the
tor-0.2.3.25 tagged version. I built both versions and gave them a
minimal torrc (SocksPort, Log, DataDir, ControlPort). After the Tor
process built a circuit I used a random page from the hidden wiki and
tried to access it. If it failed, I tried either the HS from TorProject
or DDG. If it succeeded, I built a new circuit and tried another HS.

During the first tests I used the hotel network, which was kind of
flaky. With a more stable connection I tested nearly 20 hidden services
and found no difference in the behaviour of both Tor versions. Both
failed on one random HS and opened all other reasonably fast.

While this is no final proof it is good evidence that there is no
connection between failing hidden services and TAP/ntor. So maybe we
need another theory to test. ;)

Re: [tor-dev] Proposal 203: Avoiding censorship by impersonating an HTTPS server

Some ideas:
- some random content with a CC license
  We could have a list or something of CC-licensed content. The
  webserver mirrors either the whole site or some subsites. I'm thinking
  of some Wikipedia sites or books from Project Gutenberg.
- country related content
  We could check the users IP address and try to geolocate it. Based on
  that country information the webserver could deliver some local
  content. But where should we get country-specific content.
- 451
  If someone is in trolling mood, he just can deliver a 451 error. ;)
- Login page/random fresh installation
  We could also present some page which looks like a valid login page or
  a fresh installation (Apache, Mediawiki or something other popular).
  Another similar idea is it to deliver some error page, like a blank
  page with a MySQL-, PHP-, Tomcat or any other error message.
