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.

2019-10-10Rework how our providers are builtRichard Levitte
We put almost everything in these internal static libraries: libcommon Block building code that can be used by all our implementations, legacy and non-legacy alike. libimplementations All non-legacy algorithm implementations and only them. All the code that ends up here is agnostic to the definitions of FIPS_MODE. liblegacy All legacy implementations. libnonfips Support code for the algorithm implementations. Built with FIPS_MODE undefined. Any code that checks that FIPS_MODE isn't defined must end up in this library. libfips Support code for the algorithm implementations. Built with FIPS_MODE defined. Any code that checks that FIPS_MODE is defined must end up in this library. The FIPS provider module is built from providers/fips/*.c and linked with libimplementations, libcommon and libfips. The Legacy provider module is built from providers/legacy/*.c and linked with liblegacy, libcommon and libcrypto. If module building is disabled, the object files from liblegacy and libcommon are added to libcrypto and the Legacy provider becomes a built-in provider. The Default provider module is built-in, so it ends up being linked with libimplementations, libcommon and libnonfips. For libcrypto in form of static library, the object files from those other libraries are simply being added to libcrypto.

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.

2016-02-20Always build library object files with shared library cflagsRichard Levitte
This takes us away from the idea that we know exactly how our static libraries are going to get used. Instead, we make them available to build shareable things with, be it other shared libraries or DSOs. On the other hand, we also have greater control of when the shared library cflags. They will never be used with object files meant got binaries, such as apps/openssl or test/test*. With unified, we take this a bit further and prepare for having to deal with extra cflags specifically to be used with DSOs (dynamic engines), libraries and binaries (applications).

2015-05-22Fix the update target and remove duplicate file updatesRichard Levitte
We had updates of certain header files in both Makefile.org and the Makefile in the directory the header file lived in. This is error prone and also sometimes generates slightly different results (usually just a comment that differs) depending on which way the update was done. This removes the file update targets from the top level Makefile, adds an update: target in all Makefiles and has it depend on the depend: or local_depend: targets, whichever is appropriate, so we don't get a double run through the whole file tree.
