JFTR, this patch that was added in openssl-3 is breaking python3* in staging:N * Make file access errors much more readable: APPS load_key_certs_crls() openssl-OSSL_STORE_open_ex-Prevent-spurious-error-unregister.patch it appears it is subject of multiple regressions, I see merged and unmerged fixes in this area as followup of it. I'm trying to find the right set of patches to cherry-pick onwards, but if we don't have a strong reason to keep it, dropping it would fix 3-4 build failures.
