2022-10-05Stop raising ERR_R_MALLOC_FAILURE in most placesRichard Levitte
Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and at least handle the file name and line number they are called from, there's no need to report ERR_R_MALLOC_FAILURE where they are called directly, or when SSLfatal() and RLAYERfatal() is used, the reason `ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`. There were a number of places where `ERR_R_MALLOC_FAILURE` was reported even though it was a function from a different sub-system that was called. Those places are changed to report ERR_R_{lib}_LIB, where {lib} is the name of that sub-system. Some of them are tricky to get right, as we have a lot of functions that belong in the ASN1 sub-system, and all the `sk_` calls or from the CRYPTO sub-system. Some extra adaptation was necessary where there were custom OPENSSL_malloc() wrappers, and some bugs are fixed alongside these changes.

2020-10-15Rename OPENSSL_CTX prefix to OSSL_LIB_CTXDr. Matthias St. Pierre
Many of the new types introduced by OpenSSL 3.0 have an OSSL_ prefix, e.g., OSSL_CALLBACK, OSSL_PARAM, OSSL_ALGORITHM, OSSL_SERIALIZER. The OPENSSL_CTX type stands out a little by using a different prefix. For consistency reasons, this type is renamed to OSSL_LIB_CTX.

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.

2019-07-15Make sure all BIGNUM operations work within the FIPS providerMatt Caswell
The FIPS provider does not have a default OPENSSL_CTX so, where necessary, we need to ensure we can always access an explicit OPENSSL_CTX. We remove functions from the FIPS provider that use the default OPENSSL_CTX, and fixup some places which were using those removed functions.

Various things just turned on/off asserts, mainly for checking non-NULL arguments, which is now removed: camellia, bn_ctx, crypto/modes.

For a local variable: TYPE *p; Allocations like this are "risky": p = OPENSSL_malloc(sizeof(TYPE)); if the type of p changes, and the malloc call isn't updated, you could get memory corruption. Instead do this: p = OPENSSL_malloc(sizeof(*p)); Also fixed a few memset() calls that I noticed while doing this. Reviewed-by: Richard Levitte <levitte@openssl.org>

2004-03-25Replace the BN_CTX implementation with my current work. I'm leaving theGeoff Thorpe
little TODO list in there as well as the debugging code (only enabled if BN_CTX_DEBUG is defined). I'd appreciate as much review and testing as can be spared for this. I'll commit some changes to other parts of the bignum code shortly to make better use of this implementation (no more fixed size limitations). Note also that under identical optimisations, I'm seeing a noticable speed increase over openssl-0.9.7 - so any feedback to confirm/deny this on other systems would also be most welcome.
2004-03-13Document a change I'd already made, and at the same time, correct theGeoff Thorpe

2004-03-09More changes coming out of the bignum auditing. BN_CTX_get() should ideallyGeoff Thorpe
return a "zero" bignum as BN_new() does - so reset 'top'. During BN_CTX_end(), released bignums should be consistent so enforce this in debug builds. Also, reduce the number of wasted BN_clear_free() calls from BN_CTX_end() (typically by 75% or so). Submitted by: Nils Larsch Reviewed by: Geoff Thorpe, Ulf Möller
