| * Improvements in X.509 cert handling for python bindingsRené Korthaus2016-02-202-17/+89
| | | | | | | | | | | | | | | | Add implementation for ffi botan_x509_cert_get_public_key(). Add subject_dn() function to python x509_cert class. Have python x509_cert constructor take a buffer alternatively. Have python x509_cert functions time_starts() and time_expires() return a python timestamp.
* | Add more tests for modular inverseJack Lloyd2016-02-212-4/+475
| | | | | | | | | | The result of fuzzing with AFL for a while, then running cmin on the result.
* | Avoid some Wshadows in GCC 4.8Jack Lloyd2016-02-203-11/+10
|/ | | | | | | | | | | | | | | In GCC 4.7 and 4.8, Wshadow also warns if a local variable conflicts with a member function. This was changed in GCC 4.9 (GCC bugzilla 57709) but causes a lot of warnings on Travis which is on 4.8. Clang's Wshadow behaves like GCC 4.9 The worst offendor was Exception's constructor argument being named `what` which conflicts with the member function of the same name, being in a public header this causes so many warnings the Travis log files are truncated. This fixes Exception and a couple of others. Fixing all cases would be a slog that I'm not up for right at the moment.

| | | | | | Removes a fair number of the power mod test cases for size and test time. Would be better to add a randomized or fuzzer-based test. Otherwise no change.
* Add constant time conditional swap, add, sub for bigint wordsJack Lloyd2016-02-175-2/+233
| | | | | | | | | Not optimized and relies on asm support for const time word_add/word_sub instructions. Fix a bug introduced in 46e9a89 - unpoison needs to call the valgrind API with the pointer rather than the reference. Caused values not to be unpoisoned.
* Reject zero length TLS records out of hand.Jack Lloyd2016-02-161-4/+11
| | | | | | | | | | | | | | | | | Later checks on the record length in CCS and record handling already rejected a zero length record but when reading an empty record, readbuf.size() == TLS_HEADER_SIZE and so creating the pointer byte* record_contents = &readbuf[TLS_HEADER_SIZE]; would trigger when running under (at least) GCC'S iterator debugging, and likely other iterator checkers also. Since no completely empty record is defined, reject it immediately at the record layer. Found by Juraj Somorovsky Also correct DTLS record handling for large messages: a zero length or too-long packet should be dropped rather than an exception being thrown.
* Add KDF1 as explicit dependency in MCEIESJack Lloyd2016-02-151-0/+1
| | | | | | | | | | Previously MCEIES used KEM with a raw SHA-512 hash. When the KDF oriented KEM interface was added in 72f0f0ad2a it switched to using KDF1(SHA-512) since for a 64-byte output and no salt, the output matches the original hash. This avoids breaking the format. Prevents runtime failures when MCEIES is enabled in the build but KDF1 is not. GH #369
* In compression wrappers add an overflow check before calling mallocJack Lloyd2016-02-131-3/+21
| | | | | | | | | | If malloc fails, don't save the size that was attempted. Otherwise a failing malloc followed by a free(nullptr) would zero a block of memory equal to the failed allocation starting from the null address. It's not clear if zlib,bzip2,lzma expect the return of the malloc function to be zero but LZMA at least seems to read from it before writing. Zero it.

* Fix Coverity findings in McEliece codeJack Lloyd2016-02-093-14/+20
| | | | | | | | Initialize variables in constructor in gf2m_decomp_rootfind_state Add asserts on the degree where a positive value was assumed. How polyn_gf2m handles the degree needs some work but this should do for now.
* Add asserts to help out CoverityJack Lloyd2016-02-092-0/+4
| | | | | | It somehow deduces an input that is both > 0 and for which high_bit never finds a bit set and returns 0. In both cases that would lead to block being 0 and a negative shift.
* Check result of dynamic_castJack Lloyd2016-02-091-10/+17
| | | | | | Unlikely to fail in this case but anything's possible. Found by Coverity
* Removes randomization from choice of keys in X509 test.Jack Lloyd2016-02-091-17/+15
| | | | | | | Would be better to iterate over all of the key types for this type of coverage. Avoids Coverity dead code warning on the error-case throw.
* Fix memory leaks in FFI testsJack Lloyd2016-02-091-7/+16
| | | | | | | | | | Some tests only deallocated in the branch where some other test on the object succeeded. The ECDH FFI test didn't deallocate any of its objects, which was missed by valgrind before now because the test was not being run. Found by Coverity scanner
* Avoid Coverity false positiveJack Lloyd2016-02-091-1/+5
| | | | | | | | It assumes unpoison is expecting a pointer to T and sizeof(T), but the sizeof is evaluated in unpoison but only in the case of building with valgrind. Just call the valgrind API again directly

* Make SRP6 support optional in TLSJack Lloyd2016-02-0710-20/+72

* Add explicit fork check to HMAC_RNGJack Lloyd2016-02-076-85/+118
| | | | | | | | | | | Add OS functions get_process_id, get_processor_timestamp, and get_system_timestamp_ns. HMAC_RNG uses the pid call to detect forks to initiate a reseed. It also adds the output of all three functions (the pid, the CPU cycle counter, and the system timestamp) into the PRF input. Calls the new OS timer functions from hres_timer entropy source. Removes the call to QPC in es_win32 which is mostly redundant with the one in hres_timer.

* Revert GH #365 Replace deprecated Win API calls in Win32_EntropySourceJack Lloyd2016-02-061-3/+3
| | | | | | | | | | | | | | | | | | Thinking it over I've realized this was not a good move; XP may be EOLed but is still widely used and even VS 2015 still supports targeting XP. It's not really the same situation as going to extra efforts for supporting SunOS 5.1 or VAX/VMS, instead it actively broke support for something which is still widely deployed. And for those building for XP the options are patch out the call (GH #416) or disable win32_stats altogether in their build. I'd like to prevent downstream distributors from having to patch, because that can get messy. And while the design of CryptGenRandom is not disclosed it apparently has changed over time and at one point (IIRC) used RC4 to generate outputs, so if there is any OS that could use some extra help generating seed material it is XP. There may be future code that really makes use of APIs added after XP - CryptoNG, TPM support, etc and then people targetting XP will have to compile out those modules. But it doesn't make sense to break it here for this small gain.
* Order the accesses to A[] in the Keccak permutation.Jack Lloyd2016-02-061-17/+17
| | | | | | Consistent speed up of about ~5% on my machine. Also tried moving all the A[] values to local registers, was slower.
* Fix two bugs in 1.11.27 which caused test failures.1.11.28Jack Lloyd2016-02-013-4/+6
| | | | | | | | | | | | | The check on each individual size in curve_mul is too strict since we rely on redc(x*1) during the on the curve computation. Fix an off by one in ressol which caused it to occasionally reject valid values. Updating version 1.11.28 since existing 1.11.27 tag already pushed :( Fix an off-by-one in ressol which would cause it to occasionly give up too early.
* Fix heap overflow in ECC point multiplicationJack Lloyd2016-02-016-4/+76
| | | | | | | | | | | | | | If affine coordinates larger than the prime modulus were given, a later multiplication could overflow the size of an allocated output buffer, which was sized based on the size of the prime. This will cause an overflow into either the system heap or if the mlock/mmap pool allocator is in use, then into the adjacent key material stored in the pool. Reported by Alex Gaynor who found it with AFL Also fix a one word overwrite in P-521 reduction. Found with AFL
* Fix (nearly) infinite loop in RESSOL (modular square root).Jack Lloyd2016-02-013-8/+43
| | | | | | | It first computed the first i for q**(2**i) == 1, then checked that i was smaller than s. Given a composite modulus (for which the algorithm does not work), the loop might do a very large amount of work before returning the failure.
