ouroboros/src/ipcpd/ipcp-data.h, branch 0.3Ouroboros main repositoryhttp://www.ouroboros.rocks/cgit/ouroboros/atom?h=0.32016-10-26T09:52:53Zlib, irmd, ipcpd: Add name querying to IPCPs2016-10-26T09:52:53ZSander Vrijderssander.vrijders@intec.ugent.be2016-10-25T11:22:51Zurn:sha1:f0646875d0bc941e339d305d0c68b13543cd6f2a
This adds the ability to query IPCPs if a name can be reached through
them, e.g. if a name is available in a DIF. This means that in the
shim-udp a DNS query is performed, in the shim-eth-llc an ARP-like
query has been added, in the local a check is done to see if the name
is registered, and in the normal currently no application is reachable
through it.
ipcpd: Improve locking in ipcp-data2016-10-23T14:00:33Zdimitri staessensdimitri.staessens@intec.ugent.be2016-10-23T14:00:33Zurn:sha1:5a2e524418154deab5cac0e65d48a8391c860eea
This solves some potential data races in the shims.
build: Compile with strict conversion2016-10-22T11:27:02Zdimitri staessensdimitri.staessens@intec.ugent.be2016-10-21T18:13:41Zurn:sha1:3cafbf3cfe5c58a6988dbfc4c29148ebb804f5c2
This has the code checked with -Wcast-qual and -Wconversion flags.
These flags were removed because SWIG generated code fails.
lib, ipcp: Revise fast path and flow interfaces2016-10-04T13:16:00Zdimitri staessensdimitri.staessens@intec.ugent.be2016-09-18T04:27:43Zurn:sha1:c96efb13edfaf9b2f2c626bd2a5d5d5afd38155f
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.

ipcpd: Fix bootstrap with api_bind2016-08-12T12:57:24Zdimitri staessensdimitri.staessens@intec.ugent.be2016-08-12T11:11:07Zurn:sha1:54b1ba99e15660e2e12dbc564f7e7428b5440446
Calling api_bind during bootstrap caused the IRMd to lock up.
api_bind is now called after the normal completes bootstrapping.

ipcp-data was not correctly destroyed.
lib: Provide first implementation of revised CDAP2016-07-05T13:43:13ZSander Vrijderssander.vrijders@intec.ugent.be2016-07-05T13:43:13Zurn:sha1:a315150a16c02f3cb694e639d5aba555fce4b4c3
This commit introduces a first version of the revised CDAP
specification. CACEP (for authentication purposes) has been separated
from CDAP. Application developers may use CDAP if they find it
useful. Within Ouroboros CDAP will be used to perform operations on
the RIB of an IPCP.
lib, irmd, ipcpd: Change of IRM API2016-06-28T14:22:01ZSander Vrijderssander.vrijders@intec.ugent.be2016-06-28T14:11:19Zurn:sha1:0d789ed8d938cc342c8f2138280795a1d5a61e3d
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.
Fixes #12
irmd: flow allocation and fast path2016-05-07T14:11:09Zdimitri staessensdimitri.staessens@intec.ugent.be2016-05-07T14:11:09Zurn:sha1:eb9f44379d5316e7f7e9311d7a66d2041eca743a
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.
lib: instance ID's are now set to the process PID2016-04-26T12:42:05Zdimitri staessensdimitri.staessens@intec.ugent.be2016-04-26T12:42:05Zurn:sha1:6be9ae98877f23b05f69e6006036fec0f6c9d338
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.
