XDP dns rate limit program has static tail call
which requires revert xdp-tool commit:
(039bdea "xdp-loader: Only load the BPF program we need from object files")
XDP dns rate limit program also uses bpf_printk helper which is not
supported on FireBeeOS since kernel CONFIG_BPF_EVENTS which allows user
to do kprobe, uprobe, tracepoint is not enabled, so bpf_printk helper is
not available, so removed bpf_printk
see discussion in [0] xdp-loader load xdp program with bpf tail call result in Bad file descriptor(-9)

This reverts commit 7773f82726.
After ISO installation in real hardware and reboot,
the boot process appears to be "stucking" in
"dracut: Switching root".
see https://github.com/vincentmli/FireBeeOS/issues/1
revert the commit resolves the issue, I suspect maybe
the output after "dractu: Switching root" is directed
to serial console? anyway revert this change temporarily.
flash image build still need to have serial console access
for better user experience when trying flash image in KVM/Libvirt
virtual environment.

- If a fresh install is done then only the DROP_HOSTILE_IN & DROP_HOSTILE_OUT
rrd directories are created.
- With the DROP_HOSTILE directory missing then when the fwhits graph is updated an error
message is caused by the inability to open the required files.
- This patch adds an if/else loop into the fwhits graph code to deal with the two cases
of the DROP_HOSTILE being present or not depending on the history and if a backup with
logs has been restored from when DROP_HOSTILE was in use.
- Tested on vm testbed and created a historical line for the hostile data when it was not
split
- There might be a simpler or better approach than this but it was the only option I
could identify. I couldn't find anything about being able to use if loops within the
RRD::Graph loop

- Update from version 2.5.0 to 2.6.0
- Update of rootfile
- This update fixes two CVE's. Not sure if IPFire would be vulnerable or not but safer
to update anyway.
- Changelog
2.6.0
Security fixes:
#789#814 CVE-2023-52425 -- Fix quadratic runtime issues with big tokens
that can cause denial of service, in partial where
dealing with compressed XML input. Applications
that parsed a document in one go -- a single call to
functions XML_Parse or XML_ParseBuffer -- were not affected.
The smaller the chunks/buffers you use for parsing
previously, the bigger the problem prior to the fix.
Backporters should be careful to no omit parts of
pull request #789 and to include earlier pull request #771,
in order to not break the fix.
#777 CVE-2023-52426 -- Fix billion laughs attacks for users
compiling *without* XML_DTD defined (which is not common).
Users with XML_DTD defined have been protected since
Expat >=2.4.0 (and that was CVE-2013-0340 back then).
Bug fixes:
#753 Fix parse-size-dependent "invalid token" error for
external entities that start with a byte order mark
#780 Fix NULL pointer dereference in setContext via
XML_ExternalEntityParserCreate for compilation with
XML_DTD undefined

This is necessary since we now have a much shorter lifetime for the host
certificate. However, it is complicated to do this is which is why we
are copying the previous certificate and generate a new CSR. This is
then signed.
A caveat of this patch is that we do not rollover the key.
