lib, irmd, ipcpd: Add name querying to IPCPs

2016-10-26T09:52:53Z

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-data

2016-10-23T14:00:33Z

This solves some potential data races in the shims.

lib: Refactor shm_du_map to shm_rdrbuff

2016-08-29T18:32:54Z

The shm_du_map is renamed to shm_rdrbuff to reflect the Random Deletion Ringbuffer used in the implementation. The close_on_exit call is removed and SDUs are cleaned up by the application in the ap_fini() call. This required a non-blocking peek() operation in the shm_ap_rbuff. Some initial implementation for future support of qos cubes has been added to the shm_rdrbuff.

ipcpd: Fix bootstrap with api_bind

2016-08-12T12:57:24Z

Calling api_bind during bootstrap caused the IRMd to lock up. api_bind is now called after the normal completes bootstrapping.

ipcpd: Fix memory leaks

2016-08-04T15:17:49Z

ipcp-data was not correctly destroyed.

lib: utils: deprecate strdup

2016-07-05T05:12:24Z

When introducing robust mutexes, ouroboros moved to POSIX 200809L which includes the strdup function in . Including will give access to strdup. Fixes #15.

irmd: flow allocation and fast path

2016-05-07T14:11:09Z

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.

ipcpd: Hide IRMd messages and fix formatting

2016-04-27T16:08:20Z

This abstracts away the IRMd messages by calling the functions from ipcp.h in the ouroboros library. It also fixes some formatting issues.

lib: instance ID's are now set to the process PID

2016-04-26T12:42:05Z

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.

irmd: reg/unreg whatevercast names

2016-04-22T15:39:30Z

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.
