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

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

Fixes warnings by some compilers about possibly uninitialized access.

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.

ipcpd: Fix missing return in ribmgr

This corrects the license statements on all files. Installed headers
are LGPLv2.1, the rest of the code is GPLv2.

Refactors the normal IPCP fmgr and ribmgr, and modifies the API for
cdap so that no callbacks are needed.

ipcpd: Change IPCP_RUNNING to IPCP_OPERATIONAL

Changes a state of the IPCP to a more correct terminology.

This fixes several bad cleanups in the normal IPCP when it is shutting
down.

Fixes issues with uint64_t not corresponding with unsigned long in
printf statements. Reorganises a calculation to reduce overflows.

This adds a directory to the normal IPCP that maps names on IPCP
addresses.

This addresses some comments after a code review by Dimitri.

This will split the IPCP state PENDING_ENROL into IPCP_CONFIG and
IPCP_BOOTING. IPCP_CONFIG is concerned only with configuring the IPCP
with the bare essence. When in IPCP_BOOTING, the IPCP will complete
its configuration by starting its policies, and thus making the IPCP
completely functioning.

This adds some helper functions to construct pathnames. Users of the
RIB manager may find these handy when constructing RIB objects.
|
|
|
|
|
|
|
| |
This changes the way RIB object attributes are set. Previously the
struct was called ro_props and it had to be allocated on the heap. Now
it follows the model of pthreads closely. This commit also changes the
callbacks of the RO subscribers to return void instead of int.
|
|
|
|
|
| |
This will add a check in the flat address policy to see if the address
is in use or not.
|
|

The RIB manager now keeps track of ROs it has already received. The
identification of a RO it knows is kept in a struct ro id. For the
deletion of these RO ids, a timerwheel to the RIB manager. It also
deletes ROs if they have a specified timeout.
|
|
|
|
|
| |
This adds the remote syncing of RIB objects. Subscribers are notified
upon receipt of new/deleted/updated RIB objects.
|
|
|
|
|
| |
This adds the ability to create/update/destroy RIB objects. Syncing
with other DIF members is not yet supported.
|
|

This will simplify the CDAP API. Now the opcode has to be given when
sending a CDAP request. Before a separate operation was provided since
some of the function parameters are unused for certain commands.
|
|
|
|
|
|
| |
This adds a policy for obtaining a flat address, and thus also the
infrastructure for policies in the IPCP. The IPCP should check if the
address is available; this is currently not there yet.
|
|
|
|
|
| |
This reduces the risk for some bugs, for instance due to
signed/unsigned mismatches and unused variables.

This commit will remove the RMT component from the normal IPCP, as
some of its functionality would else be duplicated in the FMGR. Now
all reading from flows, either N-1 or N+1 is done in the FMGR, then
either passed to the FRCT or a lookup is performed in the PFF (not
there yet) and the PDU is forwarded.

This is the first version of the fast path bootstrap in the normal
IPCP. It sets up a connection with the other end, and creates the
appropriate data structures. N+1 and N-1 SDUs are read and written and
passed through the right components.

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.

This adds the operations needed in the normal IPCP to get and set the
Protocol Control Information. It allows to allocate or release space
in the current DU. The struct pci can be serialized into newly
allocate space. Vice versa, a struct pci can be deserialized given a
DU. It allows for decreasing the TTL in the DU and for calculating the
CRC32. The TTL and CRC32 can now be selected when creating a new DIF.

Destruction of the object in the reply stage was unsafe.
|
|
|
|
|
|
| |
The state lock was reverted to an rwlock to avoid interference of
management functions with the fast path. IPCPs now close without
calling unsafe functions in the signal handler.

This adds a condition variable with a timeout to the CDAP request so
that we can respond correctly to the answer from the remote. It also
adds a timeout to the condition variable waiting on completion of
enrollment. Furthermore, for every CDAP callback a new thread is now
spawned, to avoid deadlocking in case a callback is stuck.
|
|
|
|
|
|
|
| |
This adds a condition variable to the IPCP state, so that upon state
changes any listeners to state changes can be notified. It also
replaces the read/write lock with a mutex in order to be able to do
so.
|
|
|

This adds the functionality of exchanging the static DIF information
between 2 DIF members. After exchange the enrollment is stopped, and
the IPCP that initiated enrollment transitions to the enrolled state.

This will add more functionality for enrolling two normal IPCPs with
each other. Some bugs were fixed in CDAP. Now on enrolling, an IPCP
will send a START message to the other IPCP. Next step is syncing the
RIBs.
|
|
|
|
|
|
| |
This provides the normal IPCP with bootstrapping and the initial steps
for enrollment. Next step is actually reacting to an enrollment
request and sending the data transfer constants.
|
|
|
|
|
|
| |
This adds the main loop to the normal IPCP, just like it is present in
the shim IPCPs. So in essence, the normal IPCP now reacts to all
operations from ipcp.h.
|
|
This adds the intial implementation of establishing management N-1
flows between normal IPCPs. On calling fmgr_mgmt_flow, a management
flow will be setup to a certain destination IPCP. After flow
allocation, the fd is handed to the RIB manager. The flow manager also
listens for incoming flow requests. In case they are management flows,
they are handed to the RIB manager, otherwise to the FRCT.
