7c8f20ba44 In tor_tls_get_my_certs(), set cert ptrs even on failure
Nothing should ever look at them on failure, but in some cases,
the unit tests don't check for failure, and then GCC-LTO freaks out.

7ace8d5a61 Assert that some trunnel _new() functions return non-NULL
The trunnel functions are written under the assumption that their
allocators can fail, so GCC LTO thinks they might return NULL.  In
point of fact, they're using tor_malloc() and friends, which can't
fail, but GCC won't necessarily figure that out.

Instead, have it call a mockable function.  We don't want
crypto_strongest_rand() to be mockable, since doing so creates a

in a test mode.

600e046ed3 Rename crypto_pk_check_key(), use it more reasonably, add tests
This function was a wrapper around RSA_check_key() in openssl, which
checks for invalid RSA private keys (like those where p or q are
composite, or where d is not the inverse of e, or where n != p*q).
We don't need a function like this in NSS, since unlike OpenSSL, NSS
won't let you import a bogus private key.

I've renamed the function and changed its return type to make it
more reasonable, and added a unit test for trying to read a key
where n != p*q.

later if we need one in the future.

fc0dc5aa9e Refactor tor_ersatz_socketpair() not to need socket.
This change also makes tor_ersatz_socketpair() follow the same

Nick Mathewson
60705a5719 Use NSS in crypto_rand.c
This is comparatively straightforward too, except for a couple of
twists:

   * For as long as we're building with two crypto libraries, we
     want to seed _both_ their RNGs, and use _both_ their RNGs to
     improve the output of crypto_strongest_rand()

   * The NSS prng will sometimes refuse to generate huge outputs.
     When it does, we stretch the output with SHAKE.  We only need
     this for the tests.

3a45f6ffe9 Implementation for a simple order-preserving encryption scheme.
This is meant for use when encrypting the current time within the
period in order to get a monotonically increasing revision counter
without actually revealing our view of the time.

This scheme is far from the most state-of-the-art: don't use it for
anything else without careful analysis by somebody much smarter than
I am.

See ticket #25552 for some rationale for this logic.
