Clients are now willing to send optimistic circuit data (before they
receive a 'connected' cell) to relays of any version. We used to
only do it for relays running 0.2.3.1-alpha or later, but now all
relays are new enough.
Resolves ticket 13153.
Stop modifying the value of our DirReqStatistics torrc option just
because we're not a bridge or relay. This bug was causing Tor
Browser users to write "DirReqStatistics 0" in their torrc files
as if they had chosen to change the config.
Fixes bug 4244; bugfix on 0.2.3.1-alpha.
This implements the meat of #12899. This commit should simply remove the
parts of Tor dirauths used to check whether a relay was supposed to be
named or not, it doesn't yet convert to a new mechanism for
reject/invalid/baddir/badexiting relays.
Back in 078d6bcd, we added an event number 0x20, but we didn't make
the event_mask field big enough to compensate.
Patch by "teor". Fixes 13085; bugfix on 0.2.5.1-alpha.
This is in preparation for a big patch series removing the entire Naming
system from Tor. In its wake, the approved-routers file is being
deprecated, and a replacement option to allow only pre-approved routers
is not being implemented.
When we merged the cookieauthfile creation logic in 33c3e60a37, we
accidentally took out this feature. Fixes bug 12864, bugfix on
0.2.5.1-alpha.
Also adds an ExtORPortCookieAuthFileGroupReadable, since there's no
reason not to.
Conflicts:
src/or/channel.c
src/or/circuitlist.c
src/or/connection.c
Conflicts involved removal of next_circ_id and addition of
unusable-circid tracking.
The point of the "idle timeout" for connections is to kill the
connection a while after it has no more circuits. But using "last
added a non-padding cell" as a proxy for that is wrong, since if the
last circuit is closed from the other side of the connection, we
will not have sent anything on that connection since well before the
last circuit closed.
This is part of fixing 6799.
When applied to 0.2.5, it is also a fix for 12023.
Instead of killing an or_connection_t that has had no circuits for
the last 3 minutes, give every or_connection_t a randomized timeout,
so that an observer can't so easily infer from the connection close
time the time at which its last circuit closed.
Also, increase the base timeout for canonical connections from 3
minutes to 15 minutes.
Fix for ticket 6799.
This was previously satisfied by using a temporary variable, but there
are three other instances in circuitlist.c that gcc is now bothered by,
so now introduce a CONST_TO_ORIGIN_CIRCUIT that takes a const
circuit_t instead.
If we can't detect the physical memory, the new default is 8 GB on
64-bit architectures, and 1 GB on 32-bit architectures.
If we *can* detect the physical memory, the new default is
CLAMP(256 MB, phys_mem * 0.75, MAX_DFLT)
where MAX_DFLT is 8 GB on 64-bit architectures and 2 GB on 32-bit
architectures.
You can still override the default by hand. The logic here is simply
trying to choose a lower default value on systems with less than 12 GB
of physical RAM.
This means that tor can run without needing to communicate with ioctls
to the firewall, and therefore doesn't need to run with privileges to
open the /dev/pf device node.
A new TransProxyType is added for this purpose, "pf-divert"; if the user
specifies this TransProxyType in their torrc, then the pf device node is
never opened and the connection destination is determined with getsockname
(as per pf(4)). The default behaviour (ie., when TransProxyType is "default"
when using the pf firewall) is still to assume that pf is configured with
rdr-to rules.
This isn't on by default; to get it, you need to set "TransProxyType
ipfw". (The original patch had automatic detection for whether
/dev/pf is present and openable, but that seems marginally fragile.)
Most of these are simple. The only nontrivial part is that our
pattern for using ENUM_BF was confusing doxygen by making declarations
that didn't look like declarations.
By default, after you've made a connection to port XYZ, we assume
you might still want to have an exit ready to connect to XYZ for one
hour. This patch lets you lower that interval.
Implements ticket 91
On busy servers, this function takes up something like 3-7% in
different profiles, and gets invoked every time we need to participate
as the midpoint in a hidden service.
So maybe walking through a linked list of all the circuits here wasn't
a good idea.
These options were added back in 0.1.2.5-alpha, but no longer make any
sense now that all directories support tunneled connections and
BEGIN_DIR cells. These options were on by default; now they are
always-on.
This is a fix for 10849, where TunnelDirConns 0 would break hidden
services -- and that bug arrived, I think, in 0.2.0.10-alpha.
(There is no longer meaningfully any such thing as a HS authority,
since we stopped uploading or downloading v0 hs descriptors in
0.2.2.1-alpha.)
Implements #10881, and part of #10841.
