We need to make sure that the worst thing that a weird consensus param
can do to us is to break our Tor (and only if the other Tors are
reliably broken in the same way) so that the majority of directory
authorities can't pull any attacks that are worse than the DoS that
they can trigger by simply shutting down.
One of these worse things was the cbtnummodes parameter, which could
lead to heap corruption on some systems if the value was sufficiently
large.
This commit fixes this particular issue and also introduces sanity
checking for all consensus parameters.
The spec stated that support for the helper-nodes command would be removed
in 0.1.3.x, however support for this command is still in Tor. Updated the spec
to reflect this and added a node that the command is deprecated.
Several updates to grammars for events and GETINFO results. All relate
to the fact that LongName has replaced ServerID since 0.2.2.1-alpha. See
documentation of VERBOSE_NAMES for more information. The following
grammars were changed:
* orconn-status GETINFO result
* entry-guards GETINFO result
* Path general token
* OR Connection status changed event
* New descriptors available event
In all cases a note was added about when the old grammar applies.
(1) Made the wording of the comments consistant with token names.
Digest/Fingerprint and Name/Nickname were being used interchangeably.
Better to just use Fingerprint and Nickname becuase they are the names
of the tokens.
(2) Places the tokens currently in use before the tokens used in older
versions. ServerSpec should be documented before ServerID.
(3) Added a note to the comments about ServerID that cross reference
the VERBOSE_FEATURE, allowing users to see when and why ServerID was
replaced with LongName.
(1) On by default is a bad way to describe features. Rather, they
are always on and should be viewed as a part of the control
protocol. Updated the wording in USEFEATURE to reflect this.
(2) Made descriptions of Tor versions consistant across all
features. There is the version in which a feature was introduced and
the version in which it became part of the protocol.
(3) Reworded the description of the VERBOSE_NAMES feature. The
previous wording describes the way things used to be first. Better to
lead with the current state of things and then describe how it differs
from old versions.
We decided to no longer ship expert packages for OS X because they're a
lot of trouble to keep maintained and confuse users. For those who want
a tor on OS X without Vidalia, macports is a fine option. Alternatively,
building from source is easy, too.
The polipo stuff that is still required for the Vidalia bundle build can
now be found in the torbrowser repository,
git://git.torproject.org/torbrowser.git.
* doc/Makefile.am: Move $(VAR:MOD) expansions inside "if USE_ASCIIDOC".
* doc/Makefile.am: Use proper variable name for text input files.
* doc/Makefile.am: Initialize vars to empty when !USE_ASCIIDOC.
In tor-spec.txt, instead of saying "nodes may X" instead say "Current
nodes do X; this is nonconformant. Clients should watch out for that."

At best, this patch helps us avoid sending queued relayed cells that
would get ignored during the time between when a destroy cell is
sent and when the circuit is finally freed. At worst, it lets us
release some memory a little earlier than it would otherwise.
Fix for bug #1184. Bugfix on 0.2.0.1-alpha.
* doc/Makefile.am: Change $(VAR:MOD) to ${VAR:MOD} -- make(1) on
NetBSD substitutes '$(:x)' to 'x' rather than the empty string. This
bites us in doc/ when configured with `--disable-asciidoc'. Curly
braces should work in all implementations of make(1) but this patch
changes only the places where we use the VAR:MOD expansion.
V3 authorities no longer decide not to vote on Guard+Exit. The bandwidth
weights should take care of this now.
Also, lower the max threshold for WFU to 0.98, to allow more nodes to become
guards.
Previously, we said (more or less), "a2x is broken and here's how you could
try to fix it". Instead, we now say "We need a2x to build manpages; a2x
didn't work; here is a fix that might work for you; alternatively you
could just skip manpage building."
Addresses bug 1524.
Also, give the message as a here-document rather than a bunch of echos.
There are now four ways that CBT can be disabled:
1. Network-wide, with the cbtdisabled consensus param.
2. Via config, with "LearnCircuitBuildTimeout 0"
3. Via config, with "AuthoritativeDirectory 1"
4. Via a state file write failure.
The main changes are to explain how we use git branches, how we use
changes files, and what should go into a patch. Putting these in
HACKING means that we shouldn't need to constantly refer to the or-dev
emails where we explain this stuff.
Everything that accepted the 'Circ' name handled it wrong, so even now
that we fixed the handling of the parameter, we wouldn't be able to
set it without making all the 0.2.2.7..0.2.2.10 relays act wonky.
This patch makes Tors accept the 'Circuit' name instead, so we can
turn on circuit priorities without confusing the versions that treated
the 'Circ' name as occasion to act weird.
Zax from #tor noticed that while we list docbook-xsl and docbook-xml
in our helpful error text when making the docs fails, we forgot to
also list libxml2-utils. Let's add that.
- Mention potentially negative consequence of server push, combined
with client caching
- Make the new cell type more generic, allowing other types of
exit-side transforms (suggested by nickm)
