Processors in virtual machines are *virtual*. Therefore this
only degrades the performance of the guest, but does not increase
it's security.
This patch always leaves SMT enabled in all virtual environments.

If this module is not being loaded, the kernel will mark any
GRE connection as INVALID in connection tracking, which will
be then silently dropped by a firewall rule.

Since more processes depend on good randomness, we need to
make sure that the kernel's PRNG is initialized as early as
possible.
For systems without a HWRNG, we will need to fall back to our
noisy loop and wait until we have enough randomness.
This patch also removes saving and restoring the seed. This
is no longer useful because the kernel's PRNG only takes any
input after it has successfully been seeded from other sources.
Hence adding this seed does not increase its randomness.

Records which are from the same domain than the IPFire hostname
might not be returned by unbound. This change explicitely instructs
unbound to check local data before checking the global DNS.

Due to strange NFQUEUE behaviour, traffic to remote VPN (IPsec or
OpenVPN) destinations was emitted to the internet (ppp0 or red0
interface) directly if the IPS was enabled but crashed during operation.
This patch places the IPSECBLOCK and OVPNBLOCK chains before the
ones responsible for forwarding traffic into the IPS.
Thanks to Michael for his debugging effort.

Since we are running unbound locally which always runs DNSSEC
validation, we can simply trust it and pass the ad flag on to
applications which make use of it.

on some machines the i2c sensor search take very long time
which cause hang at first boot.
Now the search is started in background and waited for max one
minute before continue load of collectd.
On such machines collectd will not get all sensors at first startup.

When unbound is running multiple threads, we have observed
that queries where sent for each thread.
Since no user should have so much DNS traffic that more than
one processor core is being saturated, this is a safe change.

It will run on all installations after this patch has been

Since DNSSEC relies on time to validate its signatures,
a common problem is that some systems (usually those without
a working RTC) are not being able to reach their time server.

Those checks have caused us a lot of trouble and are now being dropped.
Users must make sure to choose servers that support DNSSEC or enable
any of the tunneling mechanisms to be able to reach them.
