lib: shared memory map
|

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.

lib: Adds IRMd messages for the dev.h API calls
|
| | |
| | |
| | |
| | |
| | |
| | | |
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.

logs will now display as follows:
(EE): error, in red
(WW): warning, in yellow
(II): info, in green
(NI): missing code, in blue
(DB): debug messages in white

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.

lib: Add communication with IPCP daemon
|
| |
| |
| |
| |
| | |
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

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.

This moves the function definitions of list.h into a separate source

source file.

tests: added test for the du_buff structure
|
| | |
| | |
| | |
| | |
| | |

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.

tests/du_buff.c: tests the du_buff_t structure by creating different

sdu's at different locations in the du_buff_t

This replaces the stubs in the irmd and calls the actual IPCP
operations from the library. It also calls the DIF Allocator API in
one of the operations.
