* get_processor_timestamp should never return 0 if it can help it.Jack Lloyd2016-09-011-16/+59
| | | | | | | For example it used to return 0 on Linux/ARM... If no QPC or asm version, use clock_gettime if available, or else std::chrono::high_resolution_clock as a fallback.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds copyright notices for Juraj Somorovsky and Christian Mainka of Hackmanit for the changes in 7c7fcecbe6a and 6d327f879c Add Policy::check_peer_key_acceptable which lets the app set an arbitrary callback for examining keys - both the end entity signature keys from certificates and the peer PFS public keys. Default impl checks that the algorithm size matches the min keylength. This centralizes this logic and lets the application do interesting things. Adds a policy for ECDSA group size checks. Increases default policy minimums to 2048 RSA and 256 ECC. (Maybe I'm an optimist after all.)

This avoids the overhead of empty std::functions when using the virtual interface, and ensures the virtual interface works since there is no callback path that does not involve a vtable lookup. Rename the TLS::Callback functions. Since the idea is that often an owning class will pass *this as the callbacks argument, it is good to namespace the virtual functions so as not to conflict with other names chosen by the class. Specifically, prefixes all cb functions with tls_ Revert changes to use the old style alert callback (with no longer used data/len params) so no API changes are required for old code. The new Callbacks interface continues to just receive the alert code itself. Switch to virtual function interface in CLI tls_client for testing. Inline tls_server_handshake_state.h - only used in tls_server.cpp Fix tests - test looked like it was creating a new client object but it was not actually being used. And when enabled, it failed because the queues were not being emptied in between. So, fix that.

Makes it much easier to review the builds in the Travis web UI. Adds sanitizer builds for Clang on both Linux and OS X. Clang is a different compiler from GCC and its sanitizers may catch things GCC does not. I have no idea if Apple's Clang has some magic sanitizer sauce stock LLVM does not, so maybe sanitizer build on OS X can be skipped. Adds Linux cross compile targets for ARM32, ARM64, PPC64, and MinGW x86 using the cross compiler available in Trusty. All of them build and are set up to run through qemu/wine. All of the tests currently fail and so are marked as expected fail in the Travis matrix. The ARM test runs seem to have thread problems; ARM32 thread creation just fails with an exception, as if pthreads was disabled. All other tests pass ok for ARM32. On Aarch64, it looks like there is a hard crash the first time the library tries creating a thread. Both of these might be due to statically linking the binary? I have been unable to convince Ubuntu's qemu-ppc64 to execute binaries compiled by Ubuntu's ppc64 cross compiler. I'm downloading an Ubuntu ISO to try this in a VM. Running under Wine exposes several issues, both in Wine and Botan. Many functions are stubs and it appears that entropy collection fails as a result. This triggers a bug in the FFI tests which causes a crash there. A pox on time zones; _mkgmtime is a MSVC extension and is not available on MinGW GCC. Add a last resort call that just uses the localzone variant instead. Adds valgrind target, remove a bogus poison in pubkey.cpp (it was effectively asserting that all of RSA was const time which is sadly not true at all). Moves -Wshadow to maintainer mode for GCC - GCC 4.8 has a noisy variant of -Wshadow which warns if a parameter masks a function name, but this comes up all the time in constructors. Later GCCs no longer warn about this (even with -Wshadow), so the warnings are never fixed, but they cause noise in CI output and hide interesting warnings like warning: vec_lvsl is deprecated for little endian; use assignment for unaligned loads and stores [-Wdeprecated] __vector unsigned char perm = vec_lvsl(0, static_cast<u32bit*>(nullptr));
* | | | RNG changes (GH #593)Jack Lloyd2016-08-2426-356/+758
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change reseed interval logic to count calls to `randomize` rather than bytes, to match SP 800-90A Changes RNG reseeding API: there is no implicit reference to the global entropy sources within the RNGs anymore. The entropy sources must be supplied with the API call. Adds support for reseding directly from another RNG (such as a system or hardware RNG). Stateful_RNG keeps optional references to both an RNG and a set of entropy sources. During a reseed, both sources are used if set. These can be provided to HMAC_DRBG constructor. For HMAC_DRBG, SP800-90A requires we output no more than 2**16 bytes per DRBG request. We treat requests longer than that as if the caller had instead made several sequential maximum-length requests. This means it is possible for one or more reseeds to trigger even in the course of generating a single (long) output (generate a 256-bit key and use ChaCha or HKDF if this is a problem). Adds RNG::randomize_with_ts_input which takes timestamps and uses them as the additional_data DRBG field. Stateful_RNG overrides this to also include the process ID and the reseed counter. AutoSeeded_RNG's `randomize` uses this. Officially deprecates RNG::make_rng and the Serialized_RNG construtor which creates an AutoSeeded_RNG. With these removed, it would be possible to perform a build with no AutoSeeded_RNG/HMAC_DRBG at all (eg, for applications which only use the system RNG).

Precomputes the result of Ciphersuite::valid at construction time.
