Subject: [PATCH 7/7] Disable hash-based PYCs in FIPS mode
From a0c3f9ac5a4e60ab22418a3196ae46ba34e9477b Mon Sep 17 00:00:00 2001
From: Nikita Sobolev <mail@sobolevn.me>
Date: Thu, 24 Nov 2022 01:47:31 +0300
Subject: [PATCH 7/7] closes gh-99508: fix `TypeError` in
`Lib/importlib/_bootstrap_external.py` (GH-99635)
If FIPS mode is on, we can't use siphash-based HMAC
(_Py_KeyedHash), so:
- Unchecked hash PYCs can be imported, but not created
- Checked hash PYCs can not be imported nor created
- The default mode is timestamp-based PYCs, even if
SOURCE_DATE_EPOCH is set.
If FIPS mode is off, there are no changes in behavior.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1835169

From: Petr Viktorin <encukou@gmail.com>
Date: Wed, 31 Jul 2024 00:19:48 +0200
Subject: [PATCH] 00435: gh-121650: Encode newlines in headers, and verify
headers are sound (GH-122233)
Per RFC 2047:
> [...] these encoding schemes allow the
> encoding of arbitrary octet values, mail readers that implement this
> decoding should also ensure that display of the decoded data on the
> recipient's terminal will not cause unwanted side-effects
It seems that the "quoted-word" scheme is a valid way to include
a newline character in a header value, just like we already allow
undecodable bytes or control characters.
They do need to be properly quoted when serialized to text, though.
This should fail for custom fold() implementations that aren't careful
about newlines.
(cherry picked from commit 097633981879b3c9de9a1dd120d3aa585ecc2384)

# > [...] these encoding schemes allow the
