The replication of the database was missing a lock. Now the database
is first copied under lock and then sent.

This revises the RIB so it gets the complete file attribute list from
the component instead of setting some attributes in the library. This
will allow setting read/write access later on in the component
itself. The time of last change of lsdb entries in the file system is
now set to the time of the last received Link State Update for that
entry.

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"dif" and "ae" have been replaced by "layer" and "component"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 will trigger the existing member to send all entries in its
database as LSAs to the new member.

This will remove google protocol buffers from the link state routing
algorithm in the normal IPCP. It now uses packed structs, as supported
by the compilers of choice.

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.

This adds a cleanup handler to ensure the lock is released in the
event that the thread is cancelled during a write. An alternative
solution could be to make the flow write in a non-blocking way (only
the blocking write contains an execution path that has a cancellation
point).

This will let the link state policy react to flow up and down events
by notifying the PFFs of the routing instances of this event so they
can take an appropriate action.

This adds the Loop-Free Alternates (LFA) policy. In case a link goes
down a LFA may be selected to route the SDUs on without causing loops
instead of the main hop that just went down.

This adds a refcount to the graph edges so that it is only included in
the calculation if both sides announced it.

This keeps the index in the vertex struct so that is more easily
available during Dijkstra.

This returns a list as routing table instead of a pointer to a pointer
to a pointer, which simplifies the looping through the routing table
and makes it more extensible for future additions.

This turns the PDU Forwarding Function of the IPCP into a policy. For
now only the simple PFF policy is available.

The DHT will now enroll or sync when a data transfer connection is
added. This avoids the need to create a temporary data transfer
connection during enrollment (and speeds it up considerably).
The notifier system was modified to take an opaque pointer to the
object that registers as a parameter.

This adds a virtual RIB that is accessible as a filesystem that is
accessed through a fuse mountpoint (configurable , default is
/tmp/ouroboros). Currently, each IPCP will export its link state
database.

This removes the RIB as a datastructure and CDAP as the protocol
between IPCPs. CDAP, the rib and related sources are deprecated. The
link-state protocol policy is udpated to use its own protocol based on
a simple broadcast strategy along a tree. The neighbors struct is
deprecated and moved to the library as a generic notifier component.

The graph adjacency manager has been deprecated in favor of providing
an external interface into the connectivity manager so that
adjacencies can be controlled from the command line, user scripts or
user applications.
The gam and its associated policies were removed from the normal IPCP
and the IRM configuration tools. The "/members" part of the RIB was
deprecated. Removal of the gam means that initial connectivity based
on changes in the RIB can't be provided, so some changes were
required throughout the normal IPCP.
The enrollment procedure was revised to establish its own
connectivity. First, it gets boot information from a peer by
establishing a connection to the remote enrollment component and
downloading the IPCP configuratoin. This is now done using its own
protocol buffers message in anticipation of deprecation of the RIB and
CDAP for communication within a DIF.
After the boot information is downloaded, it establishes a data
transfer flow for enrolling the directory (DHT). After the DHT has
enrolled, it signals the peer to that enrollment is done, and the data
transfer connection is torn down.
Signaling connections is done via the nbs struct, which is now passed
to the connmgr, which enables control of the connectivity graph from
external sources.

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.
|
| |
|
|
This makes the routing component into a policy since different
approaches may exist to do this, depending on how high the rank of the
DIF is.
