c32a43a4d2 Move openssl version compatibility defines into a new header. 2015-11-10 10:02:21 -05:00
Nick Mathewson
347fe449fe Move formatting functions around.
The base64 and base32 functions used to be in crypto.c;
crypto_format.h had no header; some general-purpose functions were in
crypto_curve25519.c.

This patch makes a {crypto,util}_format.[ch], and puts more functions
there.  Small modules are beautiful!

0f3eeca9b8 Integrate ed25519-donna (Not yet used).
Integrate ed25519-donna into the build process, and provide an
interface that matches the `ref10` code.  Apart from the blinding and
Curve25519 key conversion, this functions as a drop-in replacement for
ref10 (verified by modifying crypto_ed25519.c).

Tests pass, and the benchmarks claim it is quite a bit faster, however
actually using the code requires additional integration work.

c66dd17980 Drop support for --digests
This is a fair amount of maintainance burden, and doesn't help much
more than the git microversion.

Closes ticket 14742.

1228dd293b Disable assertions during coverage builds
This removes roughly 5000 branches in my testing. We never want to
trigger assertions even during tests, so this is sane. Implements #15400.

7a86d53dee Clean up generated files.
Remove src/or/or_sha1.i and src/common/common_sha1.i on `make clean` and remove
the temporary micro-revision file when its no longer needed.

Additional changes;
- show a message when generating the micro-revision file.
- add the temporary micro revision file to the list of files to be removed on
  `make clean` just in case.
- fix indentation of the make rule to improve readability.

6f331645c7 Remove mempools and buf freelists
They have been off-by-default since 0.2.5 and nobody has complained. :)

Also remove the buf_shrink() function, which hasn't done anything
since we first stopped using contiguous memory to store buffers.

c2f0d52b7f Split threading-related code out of compat.c
Also, re-enable the #if'd out condition-variable code.

Work queues are going to make us hack on all of this stuff a bit more
closely, so it might not be a terrible idea to make it easier to hack.

909aa51b3f Remove configure option to disable curve25519
By now, support in the network is widespread and it's time to require
more modern crypto on all Tor instances, whether they're clients or
servers. By doing this early in 0.2.6, we can be sure that at some point
all clients will have reasonable support.

e84e1c9745 More generic passphrase hashing code, including scrypt support
Uses libscrypt when found; otherwise, we don't have scrypt and we

f9c1ba6493 Add a basic seccomp2 syscall filter on Linux
It's controlled by the new Sandbox argument.  Right now, it's rather
coarse-grained, it's Linux-only, and it may break some features.

17e9fc09c3 Coverage support: build with --enable-coverage to have tests run with gcov
If you pass the --enable-coverage flag on the command line, we build
our testing binaries with appropriate options eo enable coverage
testing.  We also build a "tor-cov" binary that has coverage enabled,
for integration tests.

On recent OSX versions, test coverage only works with clang, not gcc.
So we warn about that.

Also add a contrib/coverage script to actually run gcov with the
appropriate options to generate useful .gcov files.  (Thanks to
automake, the .o files will not have the names that gcov expects to
find.)

Also, remove generated gcda and gcno files on clean.

f7d654b81e Start work on fancy compiler tricks to expose extra stuff to our tests
This is mainly a matter of automake trickery: we build each static
library in two versions now: one with the TOR_UNIT_TESTS macro
defined, and one without.  When TOR_UNIT_TESTS is defined, we can
enable mocking and expose more functions. When it's not defined, we
can lock the binary down more.

The alternatives would be to have alternate build modes: a "testing
configuration" for building the libraries with test support, and a
"production configuration" for building them without.  I don't favor
that approach, since I think it would mean more people runnning
binaries build for testing, or more people not running unit tests.

5ea9a90d68 Fix compilation with --disable-curve25519 option
The fix is to move the two functions to format/parse base64
curve25519 public keys into a new "crypto_format.c" file.  I could
have put them in crypto.c, but that's a big file worth splitting
anyway.

Fixes bug 8153; bugfix on 0.2.4.8-alpha where I did the fix for 7869.

89ec584805 Add a wrapper around, and test and build support for, curve25519.
We want to use donna-c64 when we have a GCC with support for
64x64->uint128_t multiplying.  If not, we want to use libnacl if we
can, unless it's giving us the unsafe "ref" implementation.  And if
that isn't going to work, we'd like to use the
portable-and-safe-but-slow 32-bit "donna" implementation.

We might need more library searching for the correct libnacl,
especially once the next libnacl release is out -- it's likely to have
bunches of better curve25519 implementations.

I also define a set of curve25519 wrapper functions, though it really
shouldn't be necessary.

We should eventually make the -donna*.c files get build with
-fomit-frame-pointer, since that can make a difference.

2a4a149624 Move to non-recursive make
This gives us a few benefits:
1) make -j clean all
   this will start working, as it should. It currently doesn't.
2) increased parallel build
   recursive make will max out at number of files in a directory,
   non-recursive make doesn't have such a limitation
3) Removal of duplicate information in make files,
   less error prone

I've also slightly updated how we call AM_INIT_AUTOMAKE, as the way
that was used was not only deprecated but will be *removed* in the next
major automake release (1.13).... so probably best that we can continue
to bulid tor without requiring old automake.
