ikectl's built-in CA command for simple configurations has a fixed certificate
validity for the ca certificate. Raise this from 365 days to 4500 as expiry means
installing new CA certificates on all client machines which can cause significant
pain. This doesn't change the default validity for server certificates which
remains at 1 year (controlled by ikeca.cnf) - refreshing key and certificate
on these can be done easily without visiting all machines. ok deraadt@

Since r1.41 the extensions are included in the CSR. Thus ca_request()
already sets the extension values and returns. ca_sign() re-uses the
information to write out the extension file. Since ca_request() uses
strings stored on the stack, on return the pointers to those strings
will be unusable. To fix this, strdup() the strings passed ca_setenv()
so we can re-use them in another scope. And free() them when we clear
the environment in ca_clrenv().

Invoke openssl with -passin file rather than -key in ca_revoke().
From Andrei-Marius Radu via sthen@

ca_revoke() gets called two ways. Directly from ca_opt() with keyname
set to the cert to revoke, and indirectly from ca_create() with a
keyname set to NULL.

ca_create() sets REQ_EXT so avoid setting it in ca_revoke() when keyname
is NULL and the crl database is being initialised.

Avoids "REQ_EXT already set" when creating a CA error introduced
in rev 1.44 which set REQ_EXT unconditionally in ca_revoke().

set the client/server certificate options with all the common keyusage
and extendedkeyusage and nscerttype flags. the ikectl CA can now be used
with all kinds of other vpn tools in addition to iked and isakmpd.

check if a directory exists before trying to create it in the export
case as well, spotted by mikeb

if non absolute paths are specified in install commands assume they
are relative to /etc

allow optional paths for the install commands so we can
install into the isakmpd directory hierarchy for example.

Allow to show certificate details (show ca x cert [y]).

only try to setup a passfile when creating a CA

Allow to specify the export password on the command line (optionally, for
scripting). The "peer" argument now needs to be preceded with the "peer"
keyword, eg. ... export peer 10.1.1.1 instead of export 10.1.1.1.

- add a -q (quiet) command line option that will be used by ikeca to
set openssl batch mode: don't ask for x509 options, use the defaults.
- allow to specify the initial ca password on the command line to also
make it scriptable.
- allow to create certificates for clientAuth or serverAuth only
(eg. ikectl ca foo certificate bar server).
- cosmetics: move double declarations of ca_*() functions to parser.h.

set saner permissions on the directory we export, so we don't change
perms of /etc/iked when extracting

OK jsg@

When we create a new CA, also create an empty (but valid) CRL list.
While here, set our used defaults in the config file.

OK reyk@, jsg@

fix the permissions on directories inside the exported tarball
in the cert case.

More appropriate contents for the exported ca tarball.

Add a ca export command for EAP mode where we only require the CA cert,
and make both export commands optionally take an argument that will be
added to a peer.txt file in the exported output. Additionally
include any site specific notes from /usr/share/iked if present.

man page bits and help with the parser from reyk

use the full path to zip

Add commands to create/delete/install/import keys without
involving certificates as suggested by reyk and don't
recreate private keys if a key already exists.

ok reyk@

Add a command to revoke a certificate and generate a CRL;
make the ca install command install the CRL as well.

discussed with reyk@

switch iked pki files to /etc/iked, discussed with reyk.

Install the cert as well as the keys and make certs world
readable as suggested by reyk@

Import iked, a new implementation of the IKEv2 protocol.

iked(8) is an automatic keying daemon for IPsec, like isakmpd(8), that
IPsec creates flows and SAs automatically. Unlike isakmpd, iked(8)
implements the newer IKEv2 protocol instead of IKEv1/ISAKMP. The
daemon is still work-in-progress and not enabled in the builds, but is
already able to establish IKEv2 sessions with some other IKEv2
implementations as a responder.

with lots of help and debugging by jsg@
