Otherwise, it's possible to create streams or circuits with these
bogus IDs, leading to orphaned circuits or streams, or to ones that
can cause bandwidth DOS problems.
Fixes bug 7889; bugfix on all released Tors.
Apparently some compilers like to eliminate memset() operations on
data that's about to go out-of-scope. I've gone with the safest
possible replacement, which might be a bit slow. I don't think this
is critical path in any way that will affect performance, but if it
is, we can work on that in 0.2.4.
Fixes bug 7352.
If we completed the handshake for the v2 link protocol but wound up
negotiating the wong protocol version, we'd become so confused about
what part of the handshake we were in that we'd promptly die with an
assertion.
This is a fix for CVE-2012-2250; it's a bugfix on 0.2.3.6-alpha.
All servers running that version or later should really upgrade.
Bug and fix from "some guy from France." I tweaked his code slightly
to make it log the IP of the offending node.
Clients now consider the ClientRejectInternalAddresses config option
when using a microdescriptor consensus stanza to decide whether
an exit relay would allow exiting to an internal address. Fixes
bug 7190; bugfix on 0.2.3.1-alpha.
Our implementation of parse_short_policy was screwed up: it would
ignore the last character of every short policy. Obviously, that's
broken.
This patch fixes the busted behavior, and adds a bunch of unit tests
to make sure the rest of that function is okay.
Fixes bug 7192; fix on 0.2.3.1-alpha.
Failure to do so left us open to a remotely triggerable assertion
failure. Fixes CVE-2012-2249; bugfix on 0.2.3.6-alpha. Reported by
"some guy from France".
Allow one-hop directory fetching circuits the full "circuit build timeout"
period, rather than just half of it, before failing them and marking
the relay down. This fix should help reduce cases where clients declare
relays (or worse, bridges) unreachable because the TLS handshake takes
a few seconds to complete.
Fixes bug 6743 (one piece of bug 3443); bugfix on 0.2.2.2-alpha, where
we changed the timeout from a static 30 seconds.
We've had over two months to fix them, and didn't. Now we need
0.2.3.x stable. Yes, it would be cool to get this working in
0.2.3.x, but not at the expense of delaying every other feature that
_does_ work in 0.2.3.x. We can do a real fix in 0.2.4.
This is important, since otherwise an attacker can use timing info
to probe the internal network.
Also, add an option (ExtendAllowPrivateAddresses) so that
TestingTorNetwork won't break.
Fix for bug 6710; bugfix on all released versions of Tor.
Failure to do this would lead to double-free cases and similar,
especially when the exit's DNS was broken. See bug 6472 for full
details; this is a fix for 6472.
Anonymous patch from "cypherpunks" on trac.
This is done to avoid spurious warns. Additional log lines are also
added to try to track down the codepaths where we are somehow overcounting
success counts.
This patch extracts the inner part of config_register_addressmaps --
the part that knows about detecting wildcard addresses addresses --
and makes it into a new function. The new function is deliberately
not moved or reindented, so that the diff is smaller.
I need this to fix bug 6244.
