arma's rationale: "I think this is a bug, since people intentionally
set DirPortFrontPage, so they really do want their relay to serve that
page when it's asked for. Having it appear only sometimes (or roughly
never in Sebastian's case) makes it way less useful."
Fixes bug 1013; bugfix on 0.2.1.8-alpha.
If the Tor is running with AutomapHostsOnResolve set, it _is_
reasonable to do a DNS lookup on a .onion address. So instead we make
tor-resolve willing to try to resolve anything. Only if Tor refuses
to resolve it do we suggest to the user that resolving a .onion
address may not work.
Fix for bug 1005.
Fix an edge case where a malicious exit relay could convince a
controller that the client's DNS question resolves to an internal IP
address. Bug found and fixed by "optimist"; bugfix on 0.1.2.8-beta.
Apparently all the stuff that does a linear scan over all the DNS
cache entries can get really expensive when your DNS cache is very
large. It's hard to say how much this will help performance, since
gprof doesn't count time spent in OpenSSL or zlib, but I'd guess 10%.
Also, this patch removes calls to assert_connection_ok() from inside
the read and write callbacks, which are similarly unneeded, and a
little costlier than I'm happy with.
This is probably worth backporting to 0.2.0.
Provide a useful warning when launch_circuit tries to make us use a
node we don't want to use. Just give an info message when this is a
normal and okay situation. Fix for logging issues in bug 984.
This patch adds a function to determine whether we're in the main
thread, and changes control_event_logmsg() to return immediately if
we're in a subthread. This is necessary because otherwise we will
call connection_write_to_buf, which modifies non-locked data
structures.
Bugfix on 0.2.0.x; fix for at least one of the things currently
called "bug 977".
Tas (thanks!) noticed that when *ListenAddress is set, Tor would
still warn on startup when *Port is low and hibernation is active.
The patch parses all the *ListenAddress lines, and checks the
ports. Bugfix on 0.2.1.15-rc
If we ever add an event, then set it, then add it again, there will be
now two pointers to the event in the event base. If we delete one and
free it, the first pointer will still be there, and possibly cause a
crash later.
This patch adds detection for this case to the code paths in
eventdns.c, and works around it. If the warning message ever
displays, then a cleverer fix is in order.
{I am not too confident that this *is* the fix, since bug 957 is very
tricky. If it is, it is a bugfix on 0.2.0.}
When we got a descriptor that we (as an authority) rejected as totally
bad, we were freeing it, then using the digest in its RAM to look up its
download status. Caught by arma with valgrind. Bugfix on 0.2.1.9-alpha.
The trick is that we should assert that our next_mem pointer has not
run off the end of the array _before_ we realign the pointer, since
doing that could take us over the end... but only if we're on a system
where malloc() gives us ram in increments smaller than sizeof(void*).
This matters because a cpuworker can close its socket when it
finishes. Cpuworker typically runs in another thread, so without a
lock here, we can have a race condition and get confused about how
many sockets are open. Possible fix for bug 939.
(Don't crash immediately if we have leftover chunks to free after
freeing chunks in a buffer freelist; instead log a debugging message
that might help.)
bytes (aka 20KB/s), to match our documentation. Also update
directory authorities so they always assign the Fast flag to relays
with 20KB/s of capacity. Now people running relays won't suddenly
find themselves not seeing any use, if the network gets faster
on average.

IP address changes: directory mirrors were mistakenly telling them
their old address if they asked via begin_dir, so they never got
an accurate answer about their new address, so they just vanished
after a day. Should fix bugs 827, 883, and 900 -- but alas, only
after every directory mirror has upgraded.

ago. This change should significantly improve client performance,
especially once more people upgrade, since relays that have been
a guard for a long time are currently overloaded.

The directory authorities were refusing v3 consensus votes from
other authorities, since the votes are now 504K. Fixes bug 959;
bugfix on 0.0.2pre17 (where we raised it from 50K to 500K ;).
svn:r19194
When we used smartlist_free to free the list of succesful uploads
because we had succeeded in uploading everywhere, we did not actually
set the successful_uploads field to NULL, so later it would get freed
again in rend_service_descriptor_free. Fix for bug 948; bug
introduced in 0.2.1.6-alpha.
