There's a case when the environment variable OPENSSL_CONF is useless... when cross compiling for mingw and your wine environment has an environment variable OPENSSL_CONF. The latter will override anything that's given when starting wine and there make the use of that environment variable useless in our tests. Therefore, we should not trust it, and use explicit '-config' options instead. Reviewed-by:

Makefile.shared was designed to figure out static library names, shared library names, library version compatibility, import library names and the like on its own. This was a design for pre-1.1.0 OpenSSL because the main Makefile didn't have all that knowledge. With 1.1.0, the situation isn't the same, a lot more knowledge is included in the main Makefile, and while Makefile.shared did things right most of the time (there are some corner cases, such as the choice of .sl or .so as DSO extension on some HPUX versions), there's still an inherent fragility when one has to keep an eye on Makefile.shared to make sure it produces what the main Makefile produces. This change simplifies Makefile.shared by removing all its "intelligence" and have it depend entirely on the input from the main Makefile instead. That way, all the naming is driven from configuration data. Reviewed-by:

Based on discussion in PR #3566. Reduce duplicated code in original asn1_utctime_to_tm and asn1_generalizedtime_to_tm, and introduce a new internal function asn1_time_to_tm. This function also checks if the days in the input time string is valid or not for the corresponding month. Test cases are also added. Reviewed-by:

Add a new config param to specify how the CSPRNG should be seeded. Illegal values or nonsensical combinations (e.g., anything other than "os" on VMS or HP VOS etc) result in build failures. Add RDSEED support. Add RDTSC but leave it disabled for now pending more investigation. Refactor and reorganization all seeding files (rand_unix/win/vms) so that they are simpler. Only require 128 bits of seeding material. Many document improvements, including why to not use RAND_add() and the limitations around using load_file/write_file. Document RAND_poll(). Cleanup Windows RAND_poll and return correct status More completely initialize the default DRBG. Reviewed-by:

"Optimize" is in quotes because it's rather a "salvage operation" for now. Idea is to identify processor capability flags that drive Knights Landing to suboptimial code paths and mask them. Two flags were identified, XSAVE and ADCX/ADOX. Former affects choice of AES-NI code path specific for Silvermont (Knights Landing is of Silvermont "ancestry"). And 64-bit ADCX/ADOX instructions are effectively mishandled at decode time. In both cases we are looking at ~2x improvement. AVX-512 results cover even Skylake-X :-) Hardware used for benchmarking courtesy of Atos, experiments run by Romain Dolbeau <romain.dolbeau@atos.net>. Kudos! Reviewed-by:

Looking at http://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-90Ar1.pdf we see that in the CTR_DRBG_Update() algorithm (internal page number 51), the provided input data is (after truncation to seedlen) xor-d with the key and V vector (of length keylen and blocklen respectively). The comment in ctr_XOR notes that xor-ing with 0 is the identity function, so we can just ignore the case when the provided input is shorter than seedlen. The code in ctr_XOR() then proceeds to xor the key with the input, up to the amount of input present, and computes the remaining input that could be used to xor with the V vector, before accessing a full 16-byte stretch of the input vector and ignoring the calculated length. The correct behavior is to respect the supplied input length and only xor the indicated number of bytes. Reviewed-by:

The intention of the removed code was to check if the previous operation carried. However this does not work. The "mask" value always ends up being a constant and is all ones - thus it has no effect. This check is no longer required because of the previous commit. Reviewed-by:

In TLS mode of operation the padding value "pad" is obtained along with the maximum possible padding value "maxpad". If pad > maxpad then the data is invalid. However we must continue anyway because this is constant time code. We calculate the payload length like this: inp_len = len - (SHA_DIGEST_LENGTH + pad + 1); However if pad is invalid then inp_len ends up -ve (actually large +ve because it is a size_t). Later we do this: /* verify HMAC */ out += inp_len; len -= inp_len; This ends up with "out" pointing before the buffer which is undefined behaviour. Next we calculate "p" like this: unsigned char *p = out + len - 1 - maxpad - SHA256_DIGEST_LENGTH; Because of the "out + len" term the -ve inp_len value is cancelled out so "p" points to valid memory (although technically the pointer arithmetic is undefined behaviour again). We only ever then dereference "p" and never "out" directly so there is never an invalid read based on the bad pointer - so there is no security issue. This commit fixes the undefined behaviour by ensuring we use maxpad in place of pad, if the supplied pad is invalid. With thanks to Brian Carpenter for reporting this issue. Reviewed-by: -

SSL_clear() does not reset the SSL_METHOD if a session already exists in the SSL object. However, TLSv1.3 does not have an externally visible version fixed method (only an internal one). The state machine assumes that we are always starting from a version flexible method for TLSv1.3. The simplest solution is to just fix SSL_clear() to always reset the method if it is using the internal TLSv1.3 version fixed method. Reviewed-by:
