Mauro says:
Sphinx installation is not trivial, as not all versions are supported,
and it requires a lot of stuff for math, images and PDF/LaTeX output
to work.
So, add a script that checks if everything is fine, providing
distro-specific hints about what's needed for it to work.
Add support for detecting and installing missing packages
on Mageia. I opted to use "urpmi" at the install instructions,
as this is present on Mageia since ever. Yet, if I were using
Mageia 6, I would likely be using "dnf", as it is, IMHO,
easier to use.
Tested with Mageia 6.

Unfortunately, on some models of some architectures getting a fully
seeded CRNG is extremely difficult, and so this can result in dmesg
getting spammed for a surprisingly long time. This is really bad from
a security perspective, and so architecture maintainers really need to
do what they can to get the CRNG seeded sooner after the system is
booted. However, users can't do anything actionble to address this,
and spamming the kernel messages log will only just annoy people.
For developers who want to work on improving this situation,
CONFIG_WARN_UNSEEDED_RANDOM has been renamed to
CONFIG_WARN_ALL_UNSEEDED_RANDOM. By default the kernel will always
print the first use of unseeded randomness. This way, hopefully the
security obsessed will be happy that there is _some_ indication when
the kernel boots there may be a potential issue with that architecture
or subarchitecture. To see all uses of unseeded randomness,
developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM.

mm: fix overflow check in expand_upwards()
Using strscpy was wrong because FORTIFY_SOURCE is passing the maximum
possible size of the outermost object, but strscpy defines the count
parameter as the exact buffer size, so this could copy past the end of
the source. This would still be wrong with the planned usage of
__builtin_object_size(p, 1) for intra-object overflow checks since it's
the maximum possible size of the specified object with no guarantee of
it being that large.
Reuse of the fortified functions like this currently makes the runtime
error reporting less precise but that can be improved later on.
