* [3.12] gh-104432: Use `memcpy()` to avoid misaligned loads (GH-104433) (#107355)Miss Islington (bot)2023-07-272-7/+25
| | | | | | | | | | gh-104432: Use `memcpy()` to avoid misaligned loads (GH-104433) Fix potential unaligned memory access on C APIs involving returned sequences of `char *` pointers within the :mod:`grp` and :mod:`socket` modules. These were revealed using a ``-fsaniziter=alignment`` build on ARM macOS. (cherry picked from commit f01e4cedba1a17d321664834bb255d9d04ad16ce) Co-authored-by: Christopher Chavez <chrischavez@gmx.us>

| | | | | | | | (gh-105258) (gh-107303) The _xxsubinterpreters module was meant to only use public API. Some internal C-API usage snuck in over the last few years (e.g. gh-28969). This fixes that.

| | | | | | | | | | | | | | | | | | | | (#105199) gh-103142: Upgrade binary builds and CI to OpenSSL 1.1.1u (GH-105174) Upgrade builds to OpenSSL 1.1.1u. This OpenSSL version addresses a pile if less-urgent CVEs since 1.1.1t. The Mac/BuildScript/build-installer.py was already updated. Also updates _ssl_data_111.h from OpenSSL 1.1.1u, _ssl_data_300.h from 3.0.9, and adds a new _ssl_data_31.h file from 3.1.1 along with the ssl.c code to use it. Manual edits to the _ssl_data_300.h file prevent it from removing any existing definitions in case those exist in some peoples builds and were important (avoiding regressions during backporting). backports of this prior to 3.12 will not include the openssl 3.1 header.
