  • Revision ID: teddy@fukt.bsnet.se-20090209020113-726hq380zvp8zt97
Four new interrelated features:

1. Support using a different network interface via both initramfs.conf
   (the DEVICE setting) and the kernel command line (sixth field of
   the "ip=" option as in Linux' Documentation/nfsroot.txt).

2. Support connecting to a specified Mandos server directly using a
   kernel command line option ("mandos=connect:<ADDRESS>:<PORT>").

3. Support connecting directly to an IPv4 address (and port) using the
   "--connect" option of mandos-client.

4. Support an empty string to the --interface option to mandos-client.

* Makefile (WARN): Increase strictness by changing to
                   "-Wstrict-aliasing=1".

* debian/mandos-client.README.Debian (Use the Correct Network
  Interface): Changed to refer to initramfs.conf and nfsroot.txt.
  (Test the Server): Improve wording.
  (Non-local Connection): New section.
* initramfs-tools-script: Obey DEVICE environment variable and setting
                          from "/conf/initramfs.conf".  Also let any
                          "ip=" kernel command line option override
                          it.  Support new "mandos=connect" option.
                          Call "configure_networking" to set up IP
                          address on interface if necessary.
* plugin-runner.conf: Change example.
* plugins.d/mandos-client.c: Some whitespace and comment changes.
  (start_mandos_communication): Take an additional argument for
                                address family, all callers changed.
                                Connect to an IPv4 address if address
                                family is AF_INET.  Only set IPv6
                                scope_id for link-local addresses.
  (main): Accept empty interface name; this will not bring up any
         interface and leave the interface as unspecified.  Also do
         not restore kernel log level if lowering it failed.
* plugins.d/mandos-client.xml (OPTIONS): Document that the
                                         "--interface" option accepts
                                         an empty string.
  (EXAMPLE): Change example IPv6 address to a link-local address.
