what's happening here is that we're fetching certs for obsolete
authorities -- probably legacy signers in this case. but try to
remain general in the log message.
It's natural for the definition of bandwidth_rule_t to be with the functions
that actually care about its values. Unfortunately, this means declaring
bandwidth_rate_rule_to_string() out of sequence. Someday we'll just rename
reasons.c to strings.c, and put it at the end of or.h, and this will all be
better.
Works like the --enable-static-openssl/libevent options. Requires
--with-zlib-dir to be set. Note that other dependencies might still
pull in a dynamicly linked zlib, if you don't link them in statically
too.
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.
I'm adding this because I can never remember what stuff like 'rule 3'
means. That's the one where if somebody goes limp or taps out, the
fight is over, right?
When you mean (a=b(c,d)) >= 0, you had better not say (a=b(c,d)>=0).
We did the latter, and so whenever CircPriorityHalflife was in the
consensus, it was treated as having a value of 1 msec (that is,
boolean true).
We need to make sure we have an event_base in dns.c before we call
anything that wants one. Make sure we always have one in dns_reset()
when we're a client. Fixes bug 1341.
Now if you're a published relay and you set RefuseUnknownExits, even
if your dirport is off, you'll fetch dir info from the authorities,
fetch it early, and cache it.
In the future, RefuseUnknownExits (or something like it) will be on
by default.
From http://archives.seul.org/tor/relays/Mar-2010/msg00006.html :
As I understand it, the bug should show up on relays that don't set
Address to an IP address (so they need to resolve their Address
line or their hostname to guess their IP address), and their
hostname or Address line fails to resolve -- at that point they'll
pick a random 4 bytes out of memory and call that their address. At
the same time, relays that *do* successfully resolve their address
will ignore the result, and only come up with a useful address if
their interface address happens to be a public IP address.
When the bandwidth-weights branch added the "directory-footer"
token, and began parsing the directory footer at the first
occurrence of "directory-footer", it made it possible to fool the
parsing algorithm into accepting unsigned data at the end of a
consensus or vote. This patch fixes that bug by treating the footer
as starting with the first "directory-footer" or the first
"directory-signature", whichever comes first.
Treat strings returned from signed_descriptor_get_body_impl() as not
NUL-terminated. Since the length of the strings is available, this is
not a big problem.
Discovered by rieo.
Don't allow anything but directory-signature tokens in a consensus after
the first directory-signature token. Fixes bug in bandwidth-weights branch.

Another dereference-then-NULL-check sequence. No reports of this bug
triggered in the wild. Fixes bugreport 1256.
Thanks to ekir for discovering and reporting this bug.
Fix a dereference-then-NULL-check sequence. This bug wasn't triggered
in the wild, but we should fix it anyways in case it ever happens.
Also make sure users get a note about this being a bug when they
see it in their log.

This means that "if (E<G) {abc} else if (E>=G) {def}" can be replaced with
"if (E<G) {abc} else {def}"
Doing the second test explicitly made my mingw gcc nervous that we might
never be initializing casename.
For my 64-bit Linux system running with GCC 4.4.3-fc12-whatever, you
can't do 'printf("%lld", (int64_t)x);' Instead you need to tell the
compiler 'printf("%lld", (long long int)x);' or else it doesn't
believe the types match. This is why we added U64_PRINTF_ARG; it
looks like we needed an I64_PRINTF_ARG too.
asprintf() is a GNU extension that some BSDs have picked up: it does a printf
into a newly allocated chunk of RAM.
Our tor_asprintf() differs from standard asprintf() in that:
- Like our other malloc functions, it asserts on OOM.
- It works on windows.
- It always sets its return-field.
All other bandwidthrate settings are restricted to INT32_MAX, but
this check was forgotten for PerConnBWRate and PerConnBWBurst. Also
update the manpage to reflect the fact that specifying a bandwidth
in terabytes does not make sense, because that value will be too
large.

On Windows, we don't have a notion of ~ meaning "our homedir", so we
were deliberately using an #ifdef to avoid calling expand_filename()
in multiple places. This is silly: The right place to turn a function
into a no-op on a single platform is in the function itself, not in
every single call-site.
Spec conformance issue: The code didn't force the network-status-version
token to be the first token in a v3 vote or consensus.
Problem discovered by Parakeep.
We need to use evdns_add_server_port_with_base() when configuring
our DNS listener, because libevent segfaults otherwise. Add a macro
in compat_libevent.h to pick the correct implementation depending
on the libevent version.
Fixes bug 1143, found by SwissTorExit
The src and dest of a memcpy() call aren't supposed to overlap,
but we were sometimes calling tor_addr_copy() as a no-op.
Also, tor_addr_assign was a redundant copy of tor_addr_copy(); this patch
removes it.
We implemented ratelimiting for warnings going into the logfile, but didn't
rate-limit controller events. Now both log warnings and controller events
are rate-limited.
Tor has tor_lookup_hostname(), which prefers ipv4 addresses automatically.
Bug 1244 occured because gethostbyname() returned an ipv6 address, which
Tor cannot handle currently. Fixes bug 1244; bugfix on 0.0.2pre25.
Reported by Mike Mestnik.
The problem was that we didn't allocate enough memory on 32-bit
platforms with 64-bit time_t. The memory leak occured every time
we fetched a hidden service descriptor we've fetched before.
When calculating the is_exit flag for a routerinfo_t, we don't need
to call exit_policy_is_general_exit() if router_exit_policy_rejects_all()
tells us it definitely is an exit. This check is much cheaper than
running exit_policy_is_general_exit().
exit_policy_is_general_exit() assumed that there are no redundancies
in the passed policy, in the sense that we actively combine entries
in the policy to really get rid of any redundancy. Since we cannot
do that without massively rewriting the policy lines the relay
operators set, fix exit_policy_is_general_exit().
Fixes bug 1238, discovered by Martin Kowalczyk.
We accidentally freed the internal buffer for bridge stats when we
were writing the bridge stats file or honoring a control port
request for said data. Change the interfaces for
geoip_get_bridge_stats* to prevent these problems, and remove the
offending free/add a tor_strdup.
Fixes bug 1208.
