b67657bd95 Properly handle non-terminated strings
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.

1e1d471002 Don't believe unauthenticated info in a consensus.
Don't allow anything but directory-signature tokens in a consensus after
the first directory-signature token.  Fixes bug in bandwidth-weights branch.

86828e2004 Proper NULL checking in circuit_list_path_impl()
Another dereference-then-NULL-check sequence. No reports of this bug
triggered in the wild. Fixes bugreport 1256.

f36c36f4a8 Proper NULL checking for hsdesc publication
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.

Thanks to ekir for discovering and reporting this bug.

a9802d3322 Zero a cipher completely before freeing it
We used to only zero the first ptrsize bytes of the cipher. Since
cipher is large enough, we didn't zero too many bytes. Discovered
and fixed by ekir. Fixes bug 1254.

512cebadad For integers, if !(E<G), then we can infer that E>=G.
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.

eb10d441b6 Fix 64-bit printf issues in consensus-bw-weights5-merge.
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.

6fa8dacb97 Add a tor_asprintf() function, and use it in a couple of places.
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.

215930a7de Check snprintf return values in format_networkstatus_vote.
Maybe this is what parakeep was complaining about? Really wish he
would stick around more. Playing these guessing games is not fun :(

50d6960332 Cast our weights down to ints from int64.
They are capped to be between 0 and weight_scale (10000) by the code
just before the snprintf.

2917c0596c Restrict PerConnBWRate|Burst to INT32_MAX, update manpage
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.

d35b8dc582 Make expand_filename into a tor_strdup() alias on windows.
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.
