This commits adds the functions and messages to specify a fixed
protocol syntax during CACEP. It also revises the messages for
specifying the DT protocol syntax from the irm tool.

The IPCP will now report the DIF name and the hash value to the IRMd
as a dif_info struct. This can later be extended to add further
capability reporting. Some bugfixes in normal.

Be hashing

Currently CRC32, MD5, and SHA3 (224, 256, 384 and 512 bit) are supported.

lib, ipcpd, irmd: Register hash instead of name
|
| |
| |

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.

Setting the timeouts on flow_alloc and flow_accept will now work. This
makes some changes to the UNIX sockets used for management
communication between the APs, IRMd and IPCPs.

This makes the IRMd add/remove worker threads dynamically.
IRMD_TPM_TIMEOUT sets a timer in the threadpool manager for checking
idle threads. Each time this timer expires, it will reduce the
threadpool by one. IRMD_MIN_AV_THREADS is the minimum number of
available worker threads. If the number of active threads goes under
this threshold, the threadpool manager will create threads to get the
number of threads to IRMD_MAX_AV_THREADS, unless IRMD_MAX_THREADS is
reached.

This fixes the bug in handling multiple concurrent flow allocations.
|

|
|

The flow_alloc_res and flow_alloc_resp calls have been removed. The
flow_alloc and flow_accept calls are now both blocking and take an
additional timeout argument.
|
|
|
|
|
|
| |
Some blocking calls caused mainloops to never exit. The irm_sanitizer
will now clean up those structs before exiting. This will speed up
regular exit and avoids non-cancelling threads.

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.

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.

When starting two IRMds, the second one exits, but applications can't
contact the first because the second instance took the UNIX socket.
Now the lockfile is checked for running IRMd instances before opening
the UNIX socket.

When there is a burst of successive flow allocations for a certain
name, each such request will block a thread in the IRMD for
IRMD_REQ_ARR_TIMEOUT ms to allow the application some time to respond.
This refactors some parts of the IRMd.

The acceptor will not log disconnects with IRMd. Unexpected
disconnects will be reported and handled by management components.

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.

This removes the logfile and outputs log messages to the logging
system. The creation of the logfiles (as well as the ap_init() call)
were moved into ipcp_init() to simplify the IPCP creation and
shutdown.

If an IPCP SEGVs abruptly, the sanitizer in the IRMd would also cause
a SEGV because of looping over a registry linked list inside another
safe loop over the same list. A function is added to the registry to
avoid this.

When trying to double bootstrap, the entry name was strdup'd before
the bootstrap leaking the previous name. Now it bootstraps first and
sets the name after a successful bootstrap only.

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.

This changes the return value of the register and unregister
functions. If they were able to reg/unreg some entries a positive
value is returned, otherwise an error. Some spelling errors in the
IRMd have also been fixed.

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.
