This changes the IRM API after discussions with Dimitri. The register
operation is now split into a bind and register operation. The same
for unregister; unbind and unregister. PIDs are now used as the
application instance name. A name for a PID is only provided for
scriptability in bash. It is therefore also no longer passed down to
the IPCP. Every operation on an IPCP through the IRM API has to use
the PID. Quering of the PIDs by name is possible. The IRM tool has
been updated to use this new API as well. A subcommand 'ipcp' has been
added for operations that take effect on IPCPs only.

The installation prefix was taking a trailing backslash, while it is
common not to do so. Fixed it so that any trailing backslash is
removed by the compilation and installation scripts.

Functionality that was previously thought to be part of the DIF
Allocator is actually namespace management. Hence the file has been
renamed and the API updated.

This removes any implementation specific error numbers. Only errors
that are implementation independent should be returned.

This adds error numbers specificly for Ouroboros. It also refactors
some of the header files that are installed.

Update to POSIX 200112L to allow use of robust mutexes in the
shm_du_map. Removed the implementation of the rw_lock in favor of
pthread_rwlock_t.
Placeholder for the shm_du_map_sanitize function.

Reverting from previous commit. Even when running Ouroboros sandboxed,
the sockets and shared memory should be created in the default system
paths.
|

|
|

|

This sets the correct install directories for all the binaries,
library and header files. It also sets the right permissions on the
sockets and shared memory so that regular users can also use the
ouroboros library. Root privileges are required to run the irmd.

Added the pid of the irmd to the shm_du_map. The IRMd will check for
an existing shm_du_map. If there is an existing file, it will exit if
the owner IRMd is running or remove it if the owner IRMd is not
running.
Also simplifies calculation of the shm_du_map pointers and corrects
exiting calls for the IRMd.
Fixes #8.

The registration function has been moved to the irm tool, applications
now need to be registered by an administrator. Currently only supports
one instance per registered name, and an AP can be registered under
only one name.
The irmd can now start a registered server application on demand.
For the full functionality of the tool, execute "irm register".
AP name removed from flow allocation. Flow allocation does not send
the source ap name as it is quite useless. The accept() call now only
returns the AE name.

This introduces an IPC process that relays data between two local AP's
over the shm_du_map. Only configuration it has is a DIF name.
It required small modification elsewhere:
lib: added support for the IPCP_LOCAL type
irm: added support for the IPCP_LOCAL type
dif_config: added the IPCP_LOCAL type
tools: added support for the IPCP_LOCAL type

The cbr client will now use busy waiting by default to control the
sending rate. A --sleep option has been added to allow low CPU usage
when sending at low data rates. A --flood option has been added that
writes SDU's as fast as possible.

Adds time_utils.h to the library containing useful functions for
arithmetic with timespec and timeval structures.

The fast path has been rewritten to have certainty to read the correct
flow. Deallocation will not release port_id's or fd's until they are
explicitly released locally.

dev.c: read now only reads an SDU if is is for the correct port_id
shm_ap_rbuff: added a function peek() that returns the port_id of the
tail.

Adds a missing modulo calculation that would result in index -1 being
returned instead of zero when the ringbuffer skipped back to the
beginning.

This fixes wrong header inclusion that would make programs which are
not developed within ouroboros fail upon compilation, since they would
not find certain headers on their system.

This adds read/write locks, allowing for concurrent reads on the locked
datastructure. This is needed for the fast path.

This adds the QoS cube definition, which is an enum to select which
QoS is needed in the IPCP. An application has to use the qos_spec in
qos.h to define what it needs. The IRMd will map this unto a qos cube
definition.
Some headers are now also no longer installed on the system, since
they are only to be used within the irmd and ipcps.

This allows someone to disable the use of DNS in the shim UDP. It also
adds a config file specific for the shim UDP (which holds the nsupdate
location). Certain defines were also moved to the global config file.

This commit has a first implementation of flow allocation (the "slow
path") and read/write (the "fast path") for ouroboros. It provides
basic but unstable communications over the shared memory.
It required a lot of changes all over the stack, and fixes a number of
previously undetected issues.
This PR still need heavy revision regarding data model, locking and
cleanup.
lib/dev: modifications to the API. It now uses an ap_init() call to
set the AP name and sets the Instance ID to the pid of the process. It
also binds the AP to the shared memory and creates tables for mappings
in the fast path. A call to ap_fini() releases the resources.
lib/shm_ap_rbuff: added ring buffer for data exchange between
processes in the fast path. It passes an index in the shm_du_map.
lib/shm_du_map: rewrote API to work with calls from dev.c. Garbage
collector added. Tests updated to new API.
ipcpd/ipcp-data: removed everything related to flows, as these are
universal for all ap's and kept in ap_data (dev.c), or similar structs
for shim ipcps.
shim-udp: added flow allocator and read/write functions and shm
elements.
irmd: revised data model and structures necessary for flow allocation.
tools: echo updated to new dev.h API.
messaging system was updated to comply with new flow allocation
messages. All exchanges use pid and port_id to bootstrap the fast
path.

This adds support for adding the application name to a BIND DNS server
through the nsupdate utility.
|
|
|
|
|
| |
flow allocation now propagates on the client side up to the IPCP.
added UNKNOWN_AP and UNKNOWN_AE definitions to dev.h
|
|
|
|
|
| |
ipcp_create now returns the pid of the created process to allow for
more efficient scripting.
|
|
|
|

All instance-id's in ouroboros will be set by the system to the pid of
the process associated with this application process instance. This
means that the user has no way to choose the instance id's. Function
calls that assumed manually defined instance id's have been replaced
throughout the system.

Unregistering ap's now works. An AP now registers/unregisters its AP-I
by sending its AP name and its pid to the IRMd. The IPCPs register
whatevercast names. An AP name is currently mapped on a whatevercast
name represented by the same string literal. The IRMd allows
registration of only one AP-I per AP. A Name Space Management system
is needed in the processing system so we can resolve this completely.
Changing the stack to register whatevercast names required some changes
all over the ipcpd implemented and in the library.

Basic functions for implementation of IPC processes, and
implementation of core functions of the shim IPCP over UDP. Updates
to the build system to compile these IPC processes, as well as some
fixes in the irmd (rudimentary capturing exit signals) and some fixes
in the library, mainly relating to the messaging.
Basic implementation of creation / bootstrapping / deletion of the
shim UDP. Placeholders for other functions.

This adds dif_config to the prototype, in which one is able to specify
the parameters a DIF should have. The bootstrap operation of an IPCP
takes this as parameter and is oblivious to whether it is a shim or a
normal IPCP. The dif_config struct is also correctly serialized and
deserialized and passed opaquely to the correct IPCP. This IPCP is in
charge of deserializing it correctly.

This moves strdup to utils to make it globally available.

This adds the messages that are sent to the IPCPs related to
flows. Some messages are also sent to the IRMd (e.g. when a new flow
arrives).
|

This adds the operations related to flows to ipcp.h. Previously it
only contained operations on the IPCP level.
