ipcpd: normal: Refactor application entities and add neighbors struct

This refactors the different Application Entities of the normal
IPCP. They all listen to and use the connection manager to establish
new application connections.
This commit also adds a neighbors struct to the normal IPCP. It
contains neighbor structs that contain application
connection. Notifiers can be registered in case a neighbor changes
(added, removed, QoS changed).
The flow manager has an instance of this neighbors struct and listens
to these events to update its flow set. The routing component also
listens to these events so that it can update the FSDB if needed. The
flow manager now also creates the PFF instances and the routing
instances per QoS cube.
The RIB manager also uses this an instance of the neighbors struct and
listens to neighbor events as well.

ipcpd: normal: Add connection manager
|
| |/ /
| | |
| | |
| | |
| | |
| | |
| | | |
This adds the connection manager which allows the different AEs of the
normal IPCP to register with it. An AE can then use the connection
manager to allocate a flow to a neighbor, or to wait for a new
connection from a neighbor.

lib: Split authentication from CACEP
|
| |/ /
| | |
| | |
| | |
| | |
| | |
| | | |
By removing authentication as part of CACEP, all policies
disappear. CACEP becomes a policy-free connection establishment
protocol between Application Entities. Authentication can later be
added cleanly as a pure policy function when needed.

The AE name should not be passed over the layer boundaries. If an
application has more than one AE it should exchange this in CACEP.

The information passed to CACEP is split between the information about
the connection and the information to be used during the
authentication exchange.

This fixes bad timedwaits for the state of the reg_entry. Also
slightly revised timedwaits throughout the prototype.

tools: Continue oping server after failed write
|

| | |
| | |
| | |
| | |
| | | |
When hammering the oping thread, it will have write fails when the
buffer gets full as its flow is non-blocking. It would stop and
deallocate the flow, but should just continue.

Sometimes the receiver thread got the SDU before the writer thread has
set the sent time when testing over the local. The sent time is now
written before actually sending to avoid this.

irmd: Fix detection of IRMd
|
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
When starting two IRMds, the second one exits, but applications can't
contact the first because the second instance took the UNIX socket.
Now the lockfile is checked for running IRMd instances before opening
the UNIX socket.

lib: Exchange protocol info during CACEP
|
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
This exchanges a protocol name, a protocol version and concrete syntax
for the protocol upon CACEP. For CDAP, only version 1 and GPB are
supported. No lists for other supported versions or syntaxes are
exchanged (but the proto file supports it). CACEP fails if there is a
mismatch between the protocol names, version and syntax specified by
the communicating parties.

Revises CACEP policies to stateless library calls. It provides two
policies: an anonymous authentication policy that will generate random
credentials for the peer, and a simple authentication policy that will
return a name for the peer and an address.
Changes the normal IPCP to use the updates API calls.

This revises the endian header to let the build time checks of
endianness be performed by the standard libraries. We just check for
the OS that is being used and provide the endian functions from
OpenBSD to everyone. It also updates the SHA3 sources to use this new
header. The byte order header is removed.
