The IRMd kept a mapping from layer names to registered names, but this
is obsolete since the introduction of the query functionality.

This makes the TTL non-optional and allows the maximum (initial) value
of the TTL to be specified at bootstrap (the default is set to
60). The fd in the DT PCI is now called EID (Endpoint ID). The names
"dif" and "ae" have been replaced by "layer" and "component"
respectively in all sources.

This refactors ouroboros to use "program" instead of "application
process" and "process" instead of "application process instance" to
align with current naming in current Operating Systems courses instead
of the ISO nomenclature adopted by RINA. This change permeates through
the entire implementation. Also contains some minor other refactors.

When registering a name in a dif before binding a program to it
without auto, the IRMd would erroneously log that the binding failed.

This makes the threadpool use pthread_cancel instead of setting an
exit flag that threadpool managed threads check periodically. This
drastically reduces CPU consumption in the irmd when running a lot of
applications. It requires cancellation handlers in the ipcp and irmd
to be implemented to ensure safe cancellation during operation and
shutdown.

This revises the build system to have configuration per system
component. System settings can now be set using cmake.
The standard compliance defines were removed from configuration header
and are set in the sources where needed. Also some small code
refactors, such as moving the data for shims out of the ipcp structure
to the respective shims were performed.

All information passed over the IRMd/IPCP boundary for using IPC
services (flow allocation, registration) is now hashed. This
effectively fixes the shared namespace between DIFs and the IRMDs.
This PR also fixes some API issues (adding const identifiers),
shuffles the include headers a bit and some small bugs.

Our mailserver was migrated from intec.ugent.be to the central
ugent.be emailserver. This PR updates the header files to reflect this
change as well. Some header files were also homogenized if the
parameters within the functions were badly aligned.

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.

When there is a burst of successive flow allocations for a certain
name, each such request will block a thread in the IRMD for
IRMD_REQ_ARR_TIMEOUT ms to allow the application some time to respond.
This refactors some parts of the IRMd.

This removes the logfile and outputs log messages to the logging
system. The creation of the logfiles (as well as the ap_init() call)
were moved into ipcp_init() to simplify the IPCP creation and
shutdown.

If an IPCP SEGVs abruptly, the sanitizer in the IRMd would also cause
a SEGV because of looping over a registry linked list inside another
safe loop over the same list. A function is added to the registry to
avoid this.

This adds the ability to query IPCPs if a name can be reached through
them, e.g. if a name is available in a DIF. This means that in the
shim-udp a DNS query is performed, in the shim-eth-llc an ARP-like
query has been added, in the local a check is done to see if the name
is registered, and in the normal currently no application is reachable
through it.

The complete data model inside the IRMd has been restructured. The
bind operation was revised to allow binding of AP and AP instances and
register those names with different DIFs (see "irm bind" for details).
Server applications require to call ap_init with a server name
argument, client application that do not the be reachable over any DIF
can call ap_init(NULL). Calling ap_init for a client with a specified
name will not have adverse consequences for the application, but will
consume unnecessary resources in the IRMd.
Application servers can now be started at any point after the IRMd has
been started. Starting servers, binding AP names and registering names in
DIFs can be performed in any order that does not defy temporal logic.
Supports naming instances by their pid. In case of IPCP Instances
created with the IRM tool, the name assigned during "irm ipcp create"
can be used.
All the changes required updates in the tools.

Threads from the threadpool will now check the state of the IRMd and
exit gracefully without a need to cancel them. This avoids the unsafe
call of pthread_cancel in the signal handler.

When a pending accept is shutdown on irmd exit, there are no more
threads running, but it should also change the state to NULL. This is
now correctly handled in the cleanup of the cancellation point.
Also fixed a busy wait with a condition variable.

|

|
|
|
|
|

Flow allocation requests and registered api states revised so all
states are tracked with a condition variable. This is a more reliable
approach and improves stability of flow allocation.
Some other refactoring was also done, such as renaming port_map_entry
to irm_flow and hiding some internal structures of the registry.

The destroy now only frees after all threads stopped using the object.
Also fixes a SEGV when trying to allocate a flow to a remote name.

Easier names for the functions.The registry now uses a single list to

For locally registered processes, the IRMd will first look for the
local, then the normal, then the shim-udp. It will look for a normal,
a shim-eth-llc and ultimately a shim-udp for non-local destinations.
It does not yet check if a remote destination is actually known in a
DIF.

from/with a name and not remove it from the registry entirely.

The stack used pid 0 (the scheduler) to indicate an invalid process
instance, probably as a leftover from the deprecated application
process instance id. Using -1 is a better solution.
