Subject: [PATCH 01/32] bpo-33604: Raise TypeError on missing hmac arg.
(GH-16805)
Also updates the documentation to clarify the situation surrounding
the digestmod parameter that is required despite its position in the
argument list as of 3.8.0 as well as removing old python2 era
references to "binary strings".
We indavertently had this raise ValueError in 3.8.0 for the missing
arg. This is not considered an API change as no reasonable code would
be catching this missing argument error in order to handle it.
(cherry picked from commit f33c57d5c780da1500619f548585792bb5b750ee)

Subject: [PATCH 02/32] [3.8] bpo-38270: Fix indentation of test_hmac
assertions (GH-17446) (GH-17450)
Since https://github.com/python/cpython/commit/c64a1a61e6fc542cada40eb069a239317e1af36e two assertions were indented and thus ignored when running test_hmac.
This PR fixes it. As the change is quite trivial I didn't add a NEWS entry.

From 36204b47f4f48d4be8e4772f4ab8fc39ca98934b Mon Sep 17 00:00:00 2001
From: Christian Heimes <christian@python.org>
Date: Fri, 13 Sep 2019 02:30:00 +0200
Subject: [PATCH 25/32] bpo-9216: Add usedforsecurity to hashlib constructors
(GH-16044)
The usedforsecurity keyword only argument added to the hash constructors is useful for FIPS builds and similar restrictive environment with non-technical requirements that legacy algorithms be forbidden by their implementations without being explicitly annotated as not being used for any security related purposes. Linux distros with FIPS support benefit from this being standard rather than making up their own way(s) to do it.

Kernel's getrandom() source is not yet FIPS compliant. Use OpenSSL's
DRBG in FIPS mode and disable os.getrandom() function.
