The routing now takes the results of the routing table to fill in the
forwarding table, by going through the neighbors and filling in the
right fd.
|
|
|
|
|
| |
This fixes a bad free. The table was only freed if it was NULL,
instead of the other way around.
|

This adds a check to prevent a negative malloc in case the graph
structure is empty.

The next vertex was not taken at the end of the Dijkstra calculation
loop.
|
|
|
|
|
|
|

This fixes a dumb segfault in the dijkstra calculation. If an entry
can be removed from the table it was set to NULL. However, if the
table is completely empty, the index was -1, resulting in an illegal
access into the table.

ipcpd: Increase update timeout in fmgr
|
| |
| |
| |
| | |
This works around a possible bug in glibc 2.25.

This adds routing table calculation to the graph component. The
routing instances can then periodically ask the graph component for
the routing table, and update their PFFs accordingly.

This initializes conn_info in the ribmgr and fmgr before it is passed
to cacep.

This fixes some memleaks as reported by valgrind.

The QoS spec was not being initialized before being added to the graph
structure, resulting in an error when compiled with clang.

These solve several bugfixes in the normal.

When the flow_req_arr returned a negative error, it was not handled
correctly in the local IPCP, and an access was made into a table with
a negative integer. This handles it correctly.

ipcpd: normal: Split fmgr init into init and start
|
| | |
| | |
| | |
| | |
| | |
| | | |
This split the initialization of the flow manager into an init part
and a start part. This avoids the usage of data structures that have
not been properly initialized yet.

The temporary cube parameter must be initialized if a qosspec is
passed to avoid uninitialized values for the qoscube in the prototype.

ipcpd: Fix cleanup of connmgr
|
| | | |
| | | |

This lessens the likelyhood that the CDAP SDU thread is not yet active
when a new connection starts sending CDAP messages.

This lets the routing component listen to RIB events. It listens to
/fsdb which is populated with FSOs. The graph that is kept within the
routing component is updated depending on the event that was received.
|
| | | |
| | | |
| | | |
| | | |
| | | |
| | | | |
This adds a graph structure which will be updated by routing when it
is notified about a new RIB event. The routing can then use this graph
as input for calculating the shortest path to a destination.

This makes the routing component create a Flow State Database
(FSDB). An FSDB contains Flow State Objects (FSOs). An FSO is created
when a neighbor is added, it is deleted when a neighbor is removed and
its QoS is updated when a neighbor's QoS changes.

You can now add multiple flows to a CDAP instance. This will simplify
sending messages to different peers (e.g. for syncing the RIB). A
request will now return an array of keys terminated by
CDAP_KEY_INVALID. Removes the enum from the CDAP proto file to just
take the opcode as an integer.

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.

This removes the CDAP flow class, which is no longer needed.

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.

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.

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.

This prevents assertion failures in the IPCP in some cases. IPCPs can
now safely assert the type.

This changes the address authority to follow a similar approach to
that of the other policies. No function pointers are passed to its
user anymore.

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.

Avoids some code duplication in the normal IPCP with respect to
establishing authenticated CDAP flows.

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.

Moves the definitions of paths in the RIB for the normal IPCP to a

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.
