Added --enable-openssl-checks to send all SPA packets encrypted via libfko
through the OpenSSL library to ensure that the libfko usage of AES is always
compatible with OpenSSL. This ensures that the fwknop usage of AES is properly
implemented as verified by the OpenSSL library, which is a frequently audited
high profile crypto engine. If a vulnerability is discovered in OpenSSL and a
change is made, then the --enable-openssl-checks mode will allow the test suite
to discover this in a automated fashion for fwknop.
[client] (Franck Joncourt) Contributed a patch to allow the fwknop
client to be stopped during the password entry prompt with Ctrl-C before
any SPA packet is sent on the wire.
Added a new '--pcap-file <file>' option to allow pcap files to
be processed directly by fwknopd instead of sniffing an interface. This
feature is mostly intended for debugging purposes.
Added --disable-gpg to the autoconf ./configure script
via configure.ac. This makes it easy to not have fwknop/fwknopd
link against libgpgme even if it is installed on the local system.
fwknop can be easily managed with upstart with the addition of this config.
Here is an example:
# service fwknop start
fwknop start/running, process 4269
Updated the 'make install' step to not overwrite any existing config files in
/etc/fwknop/ and instead install new copies from the source tree at
/etc/fwknop/fwknopd.conf.inst and /etc/fwknop/access.conf.inst
Set restrictive permissions on /etc/fwknop/ directory and /etc/fwknop/* files.
Current default permissions on /etc/fwknop/ and /etc/fwknop/* are too lax.
Implemented a new check to ensure that the iptables 'comment' match exists to
ensure the proper environment for fwknopd operations. This check is controlled
by the new ENABLE_IPT_COMMENT_CHECK variable, and was suggested by Hank
Leininger.
