2019-09-28Reorganize local header filesDr. Matthias St. Pierre
Apart from public and internal header files, there is a third type called local header files, which are located next to source files in the source directory. Currently, they have different suffixes like '*_lcl.h', '*_local.h', or '*_int.h' This commit changes the different suffixes to '*_local.h' uniformly.

2019-09-28Reorganize private crypto header filesDr. Matthias St. Pierre
Currently, there are two different directories which contain internal header files of libcrypto which are meant to be shared internally: While header files in 'include/internal' are intended to be shared between libcrypto and libssl, the files in 'crypto/include/internal' are intended to be shared inside libcrypto only. To make things complicated, the include search path is set up in such a way that the directive #include "internal/file.h" could refer to a file in either of these two directoroes. This makes it necessary in some cases to add a '_int.h' suffix to some files to resolve this ambiguity: #include "internal/file.h" # located in 'include/internal' #include "internal/file_int.h" # located in 'crypto/include/internal' This commit moves the private crypto headers from 'crypto/include/internal' to 'include/crypto' As a result, the include directives become unambiguous #include "internal/file.h" # located in 'include/internal' #include "crypto/file.h" # located in 'include/crypto' hence the superfluous '_int.h' suffixes can be stripped. The files 'store_int.h' and 'store.h' need to be treated specially; they are joined into a single file.

2019-09-12util/mkerr.pl: make it not depend on the function codeRichard Levitte
The output C code was made to use ERR_func_error_string() to see if a string table was already loaded or not. Since this function returns NULL always, this check became useless. Change it to use ERR_reason_error_string() instead, as there's no reason to believe we will get rid of reason strings, ever. To top it off, we rebuild all affected C sources.

2019-03-27Increase rounds of Miller-Rabin testing DH_checkJake Massimo
DH_check is used to test the validity of Diffie-Hellman parameter sets (p, q, g). Among the tests performed are primality tests on p and q, for this BN_is_prime_ex is called with the rounds of Miller-Rabin set as default. This will therefore use the average case error estimates derived from the function BN_prime_checks_for_size based on the bit size of the number tested. However, these bounds are only accurate on testing random input. Within this testing scenario, where we are checking the validity of a DH parameter set, we can not assert that these parameters are randomly generated. Thus we must treat them as if they are adversarial in nature and increase the rounds of Miller-Rabin performed. Generally, each round of Miller-Rabin can declare a composite number prime with probability at most (1/4), thus 64 rounds is sufficient in thwarting known generation techniques (even in safe prime settings - see https://eprint.iacr.org/2019/032 for full analysis). The choice of 64 rounds is also consistent with SRP_NUMBER_ITERATIONS_FOR_PRIME 64 as used in srp_Verify_N_and_g in openssl/apps/s_client.c.

2018-12-06Refactor the computation of API version limitsRichard Levitte
Previously, the API version limit was indicated with a numeric version number. This was "natural" in the pre-3.0.0 because the version was this simple number. With 3.0.0, the version is divided into three separate numbers, and it's only the major number that counts, but we still need to be able to support pre-3.0.0 version limits. Therefore, we allow OPENSSL_API_COMPAT to be defined with a pre-3.0.0 style numeric version number or with a simple major number, i.e. can be defined like this for any application: -D OPENSSL_API_COMPAT=0x10100000L -D OPENSSL_API_COMPAT=3 Since the pre-3.0.0 numerical version numbers are high, it's easy to distinguish between a simple major number and a pre-3.0.0 numerical version number and to thereby support both forms at the same time. Internally, we define the following macros depending on the value of OPENSSL_API_COMPAT: OPENSSL_API_0_9_8 OPENSSL_API_1_0_0 OPENSSL_API_1_1_0 OPENSSL_API_3 They indicate that functions marked for deprecation in the corresponding major release shall not be built if defined.

2018-09-05Fix segfault in RSA_free() (and DSA/DH/EC_KEY)Nicola Tuveri
`RSA_free()` and friends are called in case of error from `RSA_new_method(ENGINE *e)` (or the respective equivalent functions). For the rest of the description I'll talk about `RSA_*`, but the same applies for the equivalent `DSA_free()`, `DH_free()`, `EC_KEY_free()`. If `RSA_new_method()` fails because the engine does not implement the required method, when `RSA_free(RSA *r)` is called, `r->meth == NULL` and a segfault happens while checking if `r->meth->finish` is defined. This commit fixes this issue by ensuring that `r->meth` is not NULL before dereferencing it to check for `r->meth->finish`. Fixes #7102 .
