22804c0391 Check for CPUs more accurartely when ONLN != CONF. 
There are two ways to use sysconf to ask about the number of
CPUs. When we're on a VM, we would sometimes get it wrong by asking
for the number of total CPUs (say, 64) when we should have been asking
for the number of CPUs online (say, 1 or 2).

Fix for bug 8002.

8cdd8b8353 Fix numerous problems with Tor's weak RNG. 
We need a weak RNG in a couple of places where the strong RNG is
both needless and too slow.  We had been using the weak RNG from our
platform's libc implementation, but that was problematic (because
many platforms have exceptionally horrible weak RNGs -- like, ones
that only return values between 0 and SHORT_MAX) and because we were
using it in a way that was wrong for LCG-based weak RNGs.  (We were
counting on the low bits of the LCG output to be as random as the
high ones, which isn't true.)

This patch adds a separate type for a weak RNG, adds an LCG
implementation for it, and uses that exclusively where we had been
using the platform weak RNG.

49dd5ef3a3 Add and use and unlikely-to-be-eliminated memwipe() 
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.

56c0baa523 Rename all reserved C identifiers we defined 
For everything we declare that starts with _, make it end with _ instead.

This is a machine-generated patch.  To make it, start by getting the
list of reserved identifiers using:

     git ls-tree -r --name-only HEAD | grep  '\.[ch]$' | \
       xargs ctags --c-kinds=defglmpstuvx -o - | grep '^_' | \
       cut -f 1 | sort| uniq

You might need gnu ctags.

Then pipe the output through this script:
==============================

use strict;

BEGIN { print "#!/usr/bin/perl -w -i -p\n\n"; }

chomp;

next if (
     /^__attribute__/ or
     /^__func__/ or
     /^_FILE_OFFSET_BITS/ or
     /^_FORTIFY_SOURCE/ or
     /^_GNU_SOURCE/ or
     /^_WIN32/ or
     /^_DARWIN_UNLIMITED/ or
     /^_FILE_OFFSET_BITS/ or
     /^_LARGEFILE64_SOURCE/ or
     /^_LFS64_LARGEFILE/ or
     /^__cdecl/ or
     /^__attribute__/ or
     /^__func__/ or
    /^_WIN32_WINNT/);

my $ident = $_;

my $better = $ident;
$better =~ s/^_//;

$better = "${better}_";

print "s/(?<![A-Za-z0-9_])$ident(?![A-Za-z0-9_])/$better/g;\n";
==============================

Then run the resulting script on all the files you want to change.
(That is, all the C except that in src/ext.)  The resulting script was:

1e5683b167 Be more careful calling wcstombs 
The function is not guaranteed to NUL-terminate its output.  It
*is*, however, guaranteed not to generate more than two bytes per
multibyte character (plus terminating nul), so the general approach
I'm taking is to try to allocate enough space, AND to manually add a
NUL at the end of each buffer just in case I screwed up the "enough
space" thing.

Fixes bug 5909.

This would cause Tor to fail if you tried to have a PF_UNIX control

for other reasons, but there's no reason to fail like _this_.

c03a233faa Remove __ from HAVE_EXTERN_ENVIRON_DECLARED__ 
I think that the trailing __ got added in false analogy to
HAVE_MACRO__func__, HAVE_MACRO__FUNC__, and HAVE_MACRO__FUNCTION__.
But those macros actually indicate the presence of __func__,
__FUNC__, and __FUNCTION__ respectively.  The __ at the end of
HAVE_EXTERN_ENVIRON_DECLARED would only be appropriate if the
environ were declared__, whatever that means.

(As a side-note, HAVE_MACRO__func__ and so on should probably be
renamed HAVE_MACRO___func__ and so on.  But that can wait.)

This is an identifier renaming only.

077b9f19a4 If SOCK_CLOEXEC and friends fail, fall back to regular socket() calls 
Since 0.2.3.1-alpha, we've supported the Linux extensions to socket(),
open(), socketpair(), and accept() that enable us to create an fd and
make it close-on-exec with a single syscall.  This not only saves us a
syscall (big deal), but makes us less vulnerable to race conditions
where we open a socket and then exec before we can make it
close-on-exec.

But these extensions are not supported on all Linuxes: They were added
between 2.6.23 or so and 2.6.28 or so.  If you were to build your Tor
against a recent Linux's kernel headers, and then run it with a older
kernel, you would find yourselve unable to open sockets.  Ouch!

The solution here is that, when one of these syscalls fails with
EINVAL, we should try again in the portable way.  This adds an extra
syscall in the case where we built with new headers and are running
with old ones, but it will at least allow Tor to work.

Fixes bug 5112; bugfix on 0.2.3.1-alpha.

cfeafe5e77 Use a 64-bit type to hold sockets on win64. 
On win64, sockets are of type UINT_PTR; on win32 they're u_int;
elsewhere they're int.  The correct windows way to check a socket for
being set is to compare it with INVALID_SOCKET; elsewhere you see if
it is negative.

On Libevent 2, all callbacks take sockets as evutil_socket_t; we've
been passing them int.

64-bit windows.  Fixes bug 3270.

59f9097d5c Hand-conversion and audit phase of memcmp transition 
Here I looked at the results of the automated conversion and cleaned
them up as follows:

   If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
   changed it to a fast_memcmp or fast_memeq.

   Otherwise if there was a tor_memcmp that could turn into a
   tor_memneq or tor_memeq, I converted it.

This wants close attention.

[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

51e551d383 Detect and handle NULL returns from (gm/local)time_r 
These functions can return NULL for otherwise-valid values of
time_t.  Notably, the glibc gmtime manpage says it can return NULL
if the year if greater than INT_MAX, and the windows MSDN gmtime
page says it can return NULL for negative time_t values.

Also, our formatting code is not guaranteed to correctly handle
years after 9999 CE.

This patch tries to correct this by detecting NULL values from
gmtime/localtime_r, and trying to clip them to a reasonable end of
the scale.  If they are in the middle of the scale, we call it a
downright error.

Arguably, it's a bug to get out-of-bounds dates like this to begin
with.  But we've had bugs of this kind in the past, and warning when
we see a bug is much kinder than doing a NULL-pointer dereference.

Boboper found this one too.

9c7e2cf010 Locking failures on windows are indicated by EACCES 
Patch our implementation of tor_lockfile_lock() to handle this case
correctly. Also add a note that blocking behaviour differs from windows
to *nix. Fixes bug 2504, issue pointed out by mobmix.

b8a7bad799 Make payloads into uint8_t. 
This will avoid some signed/unsigned assignment-related bugs.

785086cfba Have all of our allocation functions and a few others check for underflow 
It's all too easy in C to convert an unsigned value to a signed one,
which will (on all modern computers) give you a huge signed value.  If
you have a size_t value of size greater than SSIZE_T_MAX, that is way
likelier to be an underflow than it is to be an actual request for
more than 2gb of memory in one go.  (There's nothing in Tor that
should be trying to allocate >2gb chunks.)

but this is what we do elsewhere
