The patch which adjusts the options for IPFire in the libvirtd.conf does
not apply in a newer version of libvirt. Creating this patch is harder
than to use a separate config file.
This separate config file also enables us to adjust options much faster.

These settings now will be read from
/var/ipfire/suricata/suricata-dns-servers.yaml, which will be
generated by the generate_dns_servers_file() function, located in
ids-functions.pl and called by various scripts.
Fixes#12166.

This function is used to generate a yaml file which take care of the
current used DNS configuration and should be included in the main

There is no legitimate reason to do this. Setting header X-Frame-Options

By default, even modern browsers sent the URL of ther originating
site to another one when accessing hyperlinks. This is an information
leak and may expose internal details (such as FQDN or IP address)
of an IPFire installation to a third party.

CBC ciphers contain some known vulnerabilities and should not be used
anymore. While dropping them for OpenSSL clients or public web servers
still causes interoperability problems with legacy setups, they can
be safely removed from IPFire's administrative UI.
This patch changes the used cipersuite to:
TLS_CHACHA20_POLY1305_SHA256 TLSv1.3 Kx=any Au=any Enc=CHACHA20/POLY1305(256) Mac=AEAD
TLS_AES_256_GCM_SHA384 TLSv1.3 Kx=any Au=any Enc=AESGCM(256) Mac=AEAD
TLS_AES_128_GCM_SHA256 TLSv1.3 Kx=any Au=any Enc=AESGCM(128) Mac=AEAD
ECDHE-ECDSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH Au=ECDSA Enc=AESGCM(256) Mac=AEAD
ECDHE-ECDSA-CHACHA20-POLY1305 TLSv1.2 Kx=ECDH Au=ECDSA Enc=CHACHA20/POLY1305(256) Mac=AEAD
ECDHE-ECDSA-AES128-GCM-SHA256 TLSv1.2 Kx=ECDH Au=ECDSA Enc=AESGCM(128) Mac=AEAD
ECDHE-RSA-AES256-GCM-SHA384 TLSv1.2 Kx=ECDH Au=RSA Enc=AESGCM(256) Mac=AEAD
ECDHE-RSA-CHACHA20-POLY1305 TLSv1.2 Kx=ECDH Au=RSA Enc=CHACHA20/POLY1305(256) Mac=AEAD
ECDHE-RSA-AES128-GCM-SHA256 TLSv1.2 Kx=ECDH Au=RSA Enc=AESGCM(128) Mac=AEAD
Since TLS 1.3 ciphers will be added automatically by OpenSSL, mentioning
them in "SSLCipherSuite" is unnecessary. ECDSA is preferred over RSA for
performance reasons.

We need to allow some more packets to pass through the
mangle chains so that the layer 7 filter can determine
what protocol it finds.
If L7 filter decides that a connection is of type "unknown",
we mark it as default, or it is marked with the correct class.

This reverts commit e4d242da4a.
this fails because we let QoS running and it doesn't like if the imq0
device was removed. (why imq0 can removed when it is up?)
This is useless since no ISP will evaluate those settings
any more and it has a rather large impact on throughput.

This patch modifies the connection tracking in that ways that
it sets a connection mark which will be retrieved when a packet
is being redirected to the IFB interface.
This way, we can use classification without having the packet
being sent through iptables first.

This is an alternative implementation to the Intermediate Queuing
Device (IMQ) which is an out-of-tree kernel patch and has been
criticised for being slow, especially with mutliple processors.
IFB is part of the mainline kernel and a lot less code.
