We tried to enable this back in 2020, and failed. Since then, things
may have been improved, so let's give this low-hanging fruit another
try.

Stopping services before potentially tampering with files they use is a
more sane approach than doing the latter and hope the running service
can cope with it. Suricata, at least, reportedly doesn't.

If available, the kernel will enable IOMMU (a/k/a DMA remapping) by
default on boot. To tools making use of that, particularly hypervisors,
this provides better security without any downsides.

Please refer to https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.15.57
for the changelog of this version. Since it introduces
architecture-dependent rootfile changes due to CPU side-channel
mitigations, changes to ARM rootfiles have been omitted due to the lack
of hardware.
Supposed hardening changes will be submitted separately.

The second version of this patch uses @ instead of / for sed delimiters,
which makes the command less hard to read. Since Core Update 170 already
requires a reboot at this point, the respective directive is omitted.

Excerpt from changelog:
" --- 9.16.31 released ---
5917. [bug] Update ifconfig.sh script as is miscomputed interface
identifiers when destroying interfaces. [GL #3061]
5915. [bug] Detect missing closing brace (}) and computational
overflows in $GENERATE directives. [GL #3429]
5913. [bug] Fix a race between resolver query timeout and
validation in resolver.c:validated(). Remove
resolver.c:maybe_destroy() as it is no loger needed.
[GL #3398]
5909. [bug] The server-side destination port was missing from dnstap
captures of client traffic. [GL #3309]
5905. [bug] When the TCP connection would be closed/reset between
the connect/accept and the read, the uv_read_start()
return value would be unexpected and cause an assertion
failure. [GL #3400]
5903. [bug] When named checks that the OPCODE in a response matches
that of the request, if there is a mismatch named logs
an error. Some of those error messages incorrectly
used RCODE instead of OPCODE to lookup the nemonic.
This has been corrected. [GL !6420]"

- Update from version 8.2 to 9.0
- Update of rootfile
- Remove gcc10 detection patch as this is now built into the source tarball
- Update hardening crash patch. The issue related to the gcc10 patch seems to suggest
that when that is fixed then the hardening crash patch is not required but it wasn't
100% clear. So I have left the patch in place as it only changes one line and if it
worked with the earlier versions then it should also work now. If it is decided that
it is not needed then it can always be removed at a future update.
- Changelog is massive with over 30000 lines.
vim provides fixed updates such as 8.2 and 9.0 but then issues very frequent patch
updates. For version 8.2 there are 5172 patch updates none of which have been applied
to IPFire. All of these are now built into version 9.0
https://vimhelp.org/version9.txt.html#new-9 provides the details of what is new with
version 9.0, including details of all the 5172 patches.
- Key thing for version 9.0 is that there is a new Vim9 script language which is not
backwards compatible. However the old legacy script language will continue to be
supported so all old scripts can continue to be used.
- Version 9.0 already has 48 patches released. The releases occur virtually every day
with several days having multiple patch releases.
- Once this 9.0 version of vim has been confirmed to work successfully by people
experienced in using vim (I struggle to remember the set of characters to press to
exit from an editing session), then my plan is to periodically submit an update of the
patches, although some may be missed out as they are not relevant for IPFire - such
as deleting Travis CI config and improving the recognition of some Visual Basic files.
