Take into account no_store when pushing algorithm

2024-12-20T17:20:17Z

When we put algorithm to the store, we have a fallback to the OSSL_LIB_CTX level store when store is NULL. Reviewed-by: Matt Caswell Reviewed-by: Tomas Mraz (Merged from https://github.com/openssl/openssl/pull/26197)

"Reserve" the method store when constructing methods

2022-07-20T06:28:17Z

Introducing the concept of reserving the store where a number of provided operation methods are to be stored. This avoids racing when constructing provided methods, which is especially pertinent when multiple threads are trying to fetch the same method, or even any implementation for the same given operation type. This introduces a |biglock| in OSSL_METHOD_STORE, which is separate from the |lock| which is used for more internal and finer grained locking.

Refactor method construction pre- and post-condition

2022-05-05T13:05:54Z

The existing pre- and post-condition functions are supposed to check if methods have already been created and stored, using provider operation bits. This is supposed to only be done for "permanent" method stores. However, the way the pre-condition was called, it could not know if the set of implementations to be stored is likely to end up in a "permanent" or a temporary store. It needs access to the |no_store| flag returned by the provider's operation query function, because that call was done after the pre-condition was called. This requires a bit of refactoring, primarly of |algorithm_do_this()|, but also of |ossl_method_construct_precondition()|.

CORE: Encure that cached fetches can be done per provider

2021-10-27T10:41:15Z

This mostly entails passing around a provider pointer, and handling queries that includes a pointer to a provider, where NULL means "any". This also means that there's a need to pass the provider pointer, not just down to the cache functions, but also be able to get it from ossl_method_store_fetch(). To this end, that function's OSSL_PROVIDER pointer argument is modified to be a pointer reference, so the function can answer back what provider the method comes from. Test added.

CORE: add a provider argument to ossl_method_construct()

This makes it possible to limit the search of methods to that particular provider. This uses already available possibilities in ossl_algorithm_do_all(). Reviewed-by: Tomas Mraz Reviewed-by: Matt Caswell (Merged from https://github.com/openssl/openssl/pull/16725)

CORE: Do a bit of cleanup of core fetching

2021-06-16T11:32:53Z

Some data, like the library context, were passed both through higher level callback structures and through arguments to those same higher level callbacks. This is a bit unnecessary, so we rearrange the callback arguments to simply pass that callback structure and rely on the higher level fetching functionality to pick out what data they need from that structure.
