Removes name_is_equal. Just using instance_name_cmp is encouraged. It
also removes a wrong initialization in the irm tool.

Did a rename of the struct so that it can hold all data related to an
IPCP in the system. The DIF name an IPCP belongs to is set on
bootstrap and enrolment.

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).

lib, irmd: Update communication with IRMd

All messages sent to the IRMd now also get a reply back with the
result of the operation.

This removes the custom ser/des methods for communicating with the
IPCP daemon and also uses GPB instead.
|
| | | |
| | | |
| | | |
| | | |
| | | | |
IRMd and dev.c now also use GPB instead of our own ser/des. irm_msg
struct has been dropped as well as the methods associated with it.

Removes rina_name_t from that API. Passing ap_name and api_id as
params instead. The IRM tool has been updated accordingly. Some errors
in the build related to protobuf-c have also been resolved.
|
| | | |
| | | |
| | | |
| | | |
| | | |
| | | | |
This adds a cmake file so that the build can ask to generate
protobuf-c files from .proto files. The messages between the IRM and
the library are compiled into the library.

moved the flow definition to the library and made it public.

The flow structure can be used to maintain the status of flows in ipcp
instances. It should probably not be exposed outside ipcpd's.
It has a flag FLOW_MT_SAFE which includes locking in case the IPCP has
a multithreaded implementation that may require it.

ipcpd: added shm_pci_t to manipulate PCI in shm

Updated tests. Added code to drop a corner case (packet where the tail
PCI would cross the edge of the ring buffer) because solving this very
rare case is not worth the performance hit on the ringbuffer the extra
code would incur. This means the ringbuffer might drop a very small
percentage of packets.

This adds several messages for the dev.h API calls to communicate with
the IRM daemon. The deserializing of these messages is still missing
and the irmd hasn't been updated with them either.

tools: Simple echo application
|

This adds a simple echo application written to show application how to
use the API. It also updates the dev.h header file with the insights
gained from performing this excercise.

Got rid of divisions and modulo operations.
Change in the meaning of a #define.
SHM_DU_MAP_SIZE: is now an exponent of 2. Default is 10, allowing
for 1024 blocks in the map.

Elements must be created/destroyed in order, but IPCPs can access PCI
while the PDU is in the ring buffer.
Test updated, no more waits are needed.

The shared memory map will allow passing SDU's between IPCPs
efficiently. It is a single block of managed memory. SDU's are stored
in a shm_du_buff datastructure, which is a list of blocks inside the
shared memory region. The mechanism for passing SDU's is not yet
implemented and could be either within the region or using another
local IPC mechanism.
The following things are configured at compile time:
SHM_FILE_NAME : the name. Default is "ouroboros_du_map".
SHM_DU_BUFF_BLOCK_SIZE: size of a block inside the shared memory
region. Default is the pagesize of the system.
SHM_DU_MAP_SIZE : the approximate size in bytes of the shared
memory map. The actual filesize may differ by
a small margin. Default is 4MB.

Some allocations were not freed in case the creation of a new IPCP
failed.

This adds the messages required for the IRMd to communicate with an
IPC Process through the library.

This removes some memleaks present in the sockets layer. It also fixes
the bad initialization of the difs_size param in the irm_msg.

This adds the functionality to create and destroy IPCPs. Upon creation
a new process is forked and execve'd. Upon destruction the IPCP is
destroyed by killing it with SIGTERM.

A NULL pointer was being passed instead of the actual name of the
IPCP.

This adds a test for the bitmap. During the testing I also removed
some bugs that were present in the bitmap implementation.

Tests should have "_test.c" appended and include the source they are
testing. The build system will find it in the parent directory.
Removed linked_list example test as it is now useless.
