This removes the _DEFAULT_SOURCE definition in the endian header as it
should not be there. This avoids double and conflicting definitions.

This changes the terminology to use layer instead of DIF and deprecate
the word "shim" for the IPCPs that attach to Ethernet LLC and UDP .The
terminology has not yet been changed in the variable names etc.
This reflects the design choices in Ouroboros to make IPCPs pure
resource allocators instead of also providing an "IPC service". The
Ouroboros IPCPs that attach to Ethernet and UDP implement the
allocator and are thus not really shims.

This turns the PDU Forwarding Function of the IPCP into a policy. For
now only the simple PFF policy is available.

This removes the RIB as a datastructure and CDAP as the protocol
between IPCPs. CDAP, the rib and related sources are deprecated. The
link-state protocol policy is udpated to use its own protocol based on
a simple broadcast strategy along a tree. The neighbors struct is
deprecated and moved to the library as a generic notifier component.

The graph adjacency manager has been deprecated in favor of providing
an external interface into the connectivity manager so that
adjacencies can be controlled from the command line, user scripts or
user applications.
The gam and its associated policies were removed from the normal IPCP
and the IRM configuration tools. The "/members" part of the RIB was
deprecated. Removal of the gam means that initial connectivity based
on changes in the RIB can't be provided, so some changes were
required throughout the normal IPCP.
The enrollment procedure was revised to establish its own
connectivity. First, it gets boot information from a peer by
establishing a connection to the remote enrollment component and
downloading the IPCP configuratoin. This is now done using its own
protocol buffers message in anticipation of deprecation of the RIB and
CDAP for communication within a DIF.
After the boot information is downloaded, it establishes a data
transfer flow for enrolling the directory (DHT). After the DHT has
enrolled, it signals the peer to that enrollment is done, and the data
transfer connection is torn down.
Signaling connections is done via the nbs struct, which is now passed
to the connmgr, which enables control of the connectivity graph from
external sources.

This revises the build system to have configuration per system
component. System settings can now be set using cmake.
The standard compliance defines were removed from configuration header
and are set in the sources where needed. Also some small code
refactors, such as moving the data for shims out of the ipcp structure
to the respective shims were performed.

This implements a Distributed Hash Table (DHT) based on the Kademlia
protocol, with default parameters set as used in the BitTorrent
Mainline DHT. This initial implementation is almost feature complete,
except for some things to be done after a testing period: caching and
stale peer bumping, and setting the expiration timeout via the IRM
tool.

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

Moves the definitions of paths in the RIB for the normal IPCP to a
header ribconfig.h to avoid repetition.

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.

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.

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

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

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

The release build failed since an assert was optimized out, which
resulted in a unused variable error.

This addresses some comments after a code review by Dimitri.

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.
