Control startup of PROC_CERT and PROC_IKEV2.
Currenly PROC_PARENT sends the configuration to both PROC_CERT and
PROC_IKEV2 and finishes by sending IMSG_CTL_ACTIVE to PROC_IKEV2.
However, when PROC_IKEV2 receives IMSG_CTL_ACTIVE it does not know
the state of PROC_CERT: PROC_CERT might not have processed the
initial configuration while PROC_IKEV2 already sends requests to
PROC_CERT, causing failed requests, or even crashes (NULL deref of
ca_certs).
In order to make sure that PROC_CERT is ready before
IMSG_CTL_ACTIVE is sent to PROC_IKEV2 that startup protocol
is changed as follows:
(1) PROC_PARENT sends configuration to both PROC_CERT and PROC_IKEV2
(2) PROC_PARENT sends IMSG_CTL_ACTIVE to PROC_CERT
(3) PROC_CERT acks IMSG_CTL_ACTIVE by sending it back to PROC_PARENT
(4) PROC_PARENT now knows that PROC_CERT is ready and has processed
all messages from step (1)
(5) PROC_PARENT sends IMSG_CTL_ACTIVE to PROC_IKEV2 and knows that
IMSG_CTL_ACTIVE will be processed by PROC_IKEV2 after all
messages from step (1)
(6) PROC_IKEV2 can now assume that PROC_CERT is ready because it has
already processed IMSG_CTL_ACTIVE

pledge exposed a simple bug: the unprivileged child tried to print the policy after receiving it from the parent. print_policy -> print_proto -> getprotobynumber -> pledge abort because it tried to access /etc/protocols without rpath. It was just a debugging message that can be moved to the parent (printing the policy on the sender side and not the receiver side). The parent has rpath and dns. Issue found by sthen@ with "proto etherip" OK sthen@ benno@

Remove the ikev1 stub - Since I started iked, it has an empty privsep process for ISAKMP+IKEv1. I kept it to let somebody either contribute the old protocol one day, I never intended to implement IKEv1 myself, or to add a new kind of pipe to isakmpd to hand off IKEv1 messages. As IKEv2 is widely supported by all major OS and networking vendors now, I'm happy to scrap the idea of supporting ISAKMP+IKEv1. It is still possible to use isakmpd for legacy VPNs. OK mikeb@

cleanup IKE-SA tree handling (fixes repeated-insert & double-remove) sa_new() always re-inserts an SA into the SA tree. in case of a key collision it would try to free the new SA. While doing that it would accidentially free the existing SA, since config_free_sa() does RB_REMOVE() uncoditionally. This change fixes this by: a) moving the responsibility for RB_REMOVE() to CALLER of config_free_sa() and b) by calling config_free_sa() instead of sa_free() from sa_new() It also changes to code to NEVER re-add an SA to the tree. So RB_INSERT() is ONLY called once per SA. The code also makes sure that there is always a KEY defined for this tree (ispi). ok mikeb@

get rid of acquire flows completely, as they tend to pass traffic when there's no sa established (as pointed out by reyk). instead use require mode feature to send acquires from the kernel. this allows us to get rid of the code that changes flow mode to acquire and keep all installed flows in the tree and save up on some code that deals with renegotiation. also several entities were renamed (iked_acqflows -> iked_activeflows, iked_ipsecsas -> iked_activesas, ikev2_acquire -> ikev2_acquire_sa). ok reyk

Reimplement the iked(8) policy evaluation for incoming connections to use the last matching semantics of PF. The previous rbtree-based implementation was broken and tried to do a longest prefix match. But instead of prefix match and using radix-trees to fix it I decided with mikeb@ to implement it as last matching policy evaluation. The last matching policy wins; the "quick" keyword can enforce first matching; additional keywords like "skip" are specific to iked(8). See iked.conf(5) for more details. The implementation also uses skip steps based on PF's code. It significantly speeds up the evaluation of many policies but also adds a little delay when loading them (only noticeable with thousands of policies). This allows iked(8) to scale well with thousands of configured policies but I also liked the fact to have skip steps in another piece of code. ok dhartmei@ for using his skip step code under the ISC license in policy.c ok mikeb@, jmc@

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@ ok deraadt@
