The ipcp-ops header was removed and merged into ipcp.h. The common
components dif_name and ipcp_type have been moved to the main ipcp
struct. After this move, ipcp_data only contained shim information, so
it was renamed to shim_data. The ipcp_init() function checks the type
and will only include the shim_data if the type is not an IPCP_NORMAL.
All ipcps have been adapted to this change in API.

The pci function will store offsets to avoid having to recalculate
them every time. TTL handling is removed from the fmgr, the TTL is
automatically decreased when deserializing the PCI (or set to 1 if
there is no TTL present so the PDU will be forwarded). The
deserialisation function now takes a pointer to a struct pci as input
to avoid memory allocation and release each time a PDU is
processed. Some checks have been replaced with assert() and return
values replaced with void where it makes sense.

This PR updates the normal IPCP to use the new RIB. The old ribmgr is
removed and replaced by a stub that needs to be implemented. All
components (dir, fmgr, frct) were adapted to the new RIB API. A lot
of functionality was moved outside of the ribmgr, such as the
addr_auth, which is now a component of the IPCP. The address is also
stored to the ipcpi struct. The irm tool has an option to set the gam
policy of the rib manager.

Sometimes the timerwheel test could fail because of scheduler timings
(an issue more apparent in Virtual Machines). When the first check
fails, the test will wait for another complete round of the
timerwheel. The maximum number of slots in the test is reduced to
reduce the test time.

This allows the selection of a policy for the graph adjacency
manager. Currently we only support constructing a complete graph.

After a previous commit the API of the linked list was changed. This
updates the files that were not yet merged upstream.

This commit adds the graph adjacency manager to the normal IPCP, which
sets up N-1 flows to other members.

This allows IPCPs to bind a name, so that they can announce their name
to neighbors which can then allocate a flow to them. Registering of
the name happens by an administrator. It also moves the irmd_api to
common ground, since it is used by all IPCPs.

The state must be set to IPCP_INIT before the main_loop threads are
started or else they will exit if they reach the check earlier than
the state is set.

The state of the IPCP should revert to INIT when pthread_create fails
in the normal and bootstrapping procedures.

These operations separe the starting and joining of the main ipcp
threads into ipcp_boot() and ipcp_shutdown() operations. This allows
the proper cleanup of user data and user threads after the IPCP is
requested to shut down.

This removes a bad unlock in the flow manager.

ipcpd: Refactor normal ipcp, initial commit

Reorganizes the normal IPCP a bit to make sure internal components do
not need to access the state of the IPCP. The IPCP has now a thread
calling accept and delegating it to the correct component based on the
AE name (this used to be in the fmgr).
Internal components are initialized upon enrollment or bootstrap of
the IPCP. If a step fails, the IPCP goes back to the INIT state, if
all components boot correctly, it goes to the operational state.
RIB synchronization is still done by sending a CDAP start/stop and
syncing with a ribmgr state, but needs revision later on.

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.

The main thread will wait for the IPCP_OPERATIONAL state before
starting the fmgr main thread by calling fmgr_init(), instead of the
fmgr itself waiting for that state.
|
| |
|
|
|
|
|
|
| |
Since the mainloop threadpool is created on ipcp_init and all threads
waited for on ipcp_fini, there is no need for it to be accessible from
elsewhere.

This avoids normal ipcps using the flat address policy having a high
probability for picking the same address when created from a script.

This adds a hash table that takes 64-bit integers as key and uses
separate chaining on collision. It also adds the PDU Forwarding
Function, which the Flow Manager can use to lookup the fd towards the
next hop. Routing policies will add/update/remove entries in the PFF.

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.

irmd, ipcp: Call select on FreeBSD

*BSD accept() doesn't timeout on the timeval set by setsockopt
SO_RCVTIMEO. The irmd and ipcp will now call select on the irmd fd
