The initial implementation for the ECDHE key exchange was doing the
key exchange after a flow was established. The public keys are now
sent allowg on the flow allocation messages, so that an encrypted
tunnel can be created within 1 RTT. The flow allocation steps had to
be extended to pass the opaque data ('piggybacking').

The API calls for the IPCP to inform the IRMd of IPCP creation and
incoming flow request had the pid_t in the call. This pid_t is removed
and the getpid() call is now placed inside the function. Also
refactors the cleanup for the main() functions of some of the lower
IPCPs.

This fixes the deallocation of non-initialized IPCP flows. These can
occur when some operations are not implemented.

The flow allocator now passes the full qos specification to the
endpoint, instead of just a cube. This is a more flexible
architecture, as it makes QoS cubes internal to the layers.
Adds endianness transforms for the flow allocator protocol in the
normal IPCP.

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 call ipcp_sdb_reserve to reserve memory in the rdrbuff
without directly writing to a flow. The ipcp_flow_del function was
renamed to ipcp_sdb_release. The functions operating on sdbs are moved
to their own header.

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.

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.

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.

The IPCP will now respond with an ipcp_create_r message when it fails,
informing the IRMd.
Also adds some const qualifiers in the public headers and fixes
some formatting in dev.c.

Now correctly relays the qoscube end-to-end in the stack.
A simple function specifying the cube in the spec is used for initial
testing.
The translation is now done in dev.c, but it could be moved elsewhere
when qos cabability matures and the need arises.

Receiver timeouts can now be set on a flow using the flow_set_timeout
function. Specifying NULL disables the timeout. The flow_get_timeout
function gets the value for the timeout.
This commit also deprecates fcntl in favor of flow_get_flags and
flow_set_flags functions.
struct qos_spec is typedef'd as a qosspec_t.
The tools and cdap.c are updated to use the new API.
Fixes a bug in operf client where the client's writer thread wouldn't
cancel on SIGINT.

The steps for flow deallocation have been further refined. An
operation ipcp_flow_fini() which wait for all SDUs to be read from a
flow has been added. The shim IPCPs and the local IPCP have been
adapted to this new API.
Deallocation messages have been removed from the shim IPCPs, since
there is insufficient state synchronisation between them to make this
work reliably.

The fast path will now use an incoming ring buffer per flow per
process. This necessitated the development of a new method for the
asynchronous io call, which is now based on an event queue system for
scalability (fqueue). The ipcpd's and tools have been updated to this
API.
|

IPCPs can now use ap_init() to initialize the memory. All flows are
accessed using flow descriptors, this greatly simplifies IPCP
development. Reverts the fast path to a single ap_rbuff per process.
Splits lib/ipcp into irmd/ipcp and lib/ipcp-dev. Adds a lib/shim-dev
holding tailored functions for shims. Moves the buffer_t to utils.h.
Fixes the shim-eth-llc length field. Removes the flow from shared.h.
