Hidden service clients didn't use a cached service descriptor that
was older than 15 minutes, but wouldn't fetch a new one either. Now,
use a cached descriptor no matter how old it is and only fetch a new
one when all introduction points fail. Fix for bug 997. Patch from
Marcus Griep.
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
With the last fix of task 932 (5f03d6c), client requests are only added to
the history when they happen after the start of the current history. This
conflicts with the unit tests that insert current requests first (defining
the start of the client request history) followed by requests in the past.
The fix is to insert requests in chronological order in the unit tests.
- Write geoip stats to disk every 24 hours, not every hour.
- Remove configuration options and define reasonable defaults.
- Clear history of client requests every 24 hours (which wasn't done at
all before).
Specifically if you send SIGUSR1, it will add two lines to the log file:
May 22 07:41:59.576 [notice] Our DNS cache has 3364 entries.
May 22 07:41:59.576 [notice] Our DNS cache size is approximately 1022656
bytes.
[tweaked a bit by nickm]
Really, our idiocy was that we were calling event_set() on the same
event more than once, which sometimes led to us calling event_set() on
an event that was already inserted, thus making it look uninserted.
With this patch, we just initialize the timeout events when we create
the requests and nameservers, and we don't need to worry about
double-add and double-del cases at all.
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.
Bridges are not supposed to publish router descriptors to the directory
authorities. It defeats the point of bridges when they are included in the
public relay directory.
This patch puts out a warning and exits when the node is configured as
a bridge and to publish v1, v2, or v3 descriptors at the same time.
Also fixes part of bug 932.
This addresses the first part of bug 918. Users are now warned when
they try to use hibernation in combination with a port below 1024
when they're not on Windows. We don't want to die here, because
people might run Tor as root, use a capabilities system or some
other platform that will allow them to re-attach low ports.

(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.)
Now, when you call tor --digests, it dumps the SHA1 digest of each
source file that Tor was built with. We support both 'sha1sum' and
'openssl sha1'. If the user is building from a tarball and they
haven't edited anything, they don't need any program that calculates
SHA1. If they _have_ modified a file but they don't have a program to
calculate SHA1, we try to build so we do not output digests.
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 ;).

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.
svn:r19073
tor_sscanf() only handles %u and %s for now, which will make it
adequate to replace sscanf() for date/time/IP parsing. We want this
to prevent attackers from constructing weirdly formed descriptors,
cells, addresses, HTTP responses, etc, that validate under some
locales but not others.

It seems that 64-bit Sparc Solaris demands 64-bit-aligned access to
uint64_t, but does not 64-bit-align the stack-allocated char array we
use for cpuworker tags. So this patch adds a set/get_uint64 pair, and
uses them to access the conn_id field in the tag.
