This seems to be a failed concept and causes issues with transferring
large packets through an IPsec tunnel connection.
This configures the kernel to still respond to PMTU ICMP discovery
messages, but will not try this on its own.

AES-GCM 128, 196 and 256 bit has been added to Net-to-Net and Roadwarrior section.
HMAC selection for N2N will be disabled if AES-GCM is used since GCM provides an own message authentication (GMAC).
'auth *' line in N2N.conf will be deleted appropriately if AES-GCM is used since '--tls-auth' is not available for N2N.
HMAC selection menu for Roadwarriors is still available since '--tls-auth' is available for RWs
which uses the configuered HMAC even AES-GCM has been applied.

Sending the server signature is unnecessary and might leak
some internal information (although ServerTokens is already
set to "Prod").

In the past the apache configuration was part of the backup
and may have been restored after Core Update 118 was installed
with PHP being dropped amongst other things.
This patch will make sure that only keys are being backuped.

Fixed a DoS vulnerability in the parser for PKCS#1 RSASSA-PSS
signatures that was caused by insufficient input validation.
One of the configurable parameters in algorithm identifier
structures for RSASSA-PSS signatures is the mask generation
function (MGF). Only MGF1 is currently specified for this purpose.
However, this in turn takes itself a parameter that specifies
the underlying hash function. strongSwan's parser did not
correctly handle the case of this parameter being absent,
causing an undefined data read.
This vulnerability has been registered as CVE-2018-6459.

When a tunnel that is in always-on configuration closes
unexpectedly, we can instruct strongSwan to restart it
immediately which is precisely what we do now.

ccache needs this and usually comes with an own bundled
version but fails to build in version 3.4.1.
Since this is a small library only and we really want
ccache to use compression, we will build this indepently
and let ccache use it from the system.

This can be used together but there is no need to
always install amavis when someone wants to use postfix
Signed-off-by: Michael Tremer <michael.tremer@ipfire.org>
This is outdated and half of it is not maintained any more.
Users should configure postfix themselves based on the
default configuration.
