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.

fixes memleaks in du_buff and du_buff_test
fixes bug in copy operation

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.

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.

tests/du_buff.c: tests the du_buff_t structure by creating different
size du_buff_t's and filling it with different size
sdu's at different locations in the du_buff_t
tests/CMakefile.txt: added du_buff test
lib/du_buff.c: fixed unsafe #define adding brackets

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.

Testing framework

This adds a build target 'check', which executes a test suite for
every daemon/library. Every test suite consists of a test driver that
executes a function in a file with the same name as the function. The
compile_debug script executes the 'check' target to validate there are
no regressions. Packaging is also fixed and the prototype can be
shipped as a tarball.

This moves the debugging switch down to the CMakeList associated with
every program or library. It allows to build apps individually with
debugging info on or off.

IRM command line tool

This provides the other messages that are used to communicate between
the library and the IRM Daemon. The IRM tool just calls the library
right now to see if it works. A full fledged program will be provided
in a next commit.

This adds the %s identifier in a sprintf. A non-literal was passed and
used as a literal.

Fixes two errors in the library. The return code of a write to a
socket was ignored. A non literal string was passed to sprintf as a
literal one.

Initial support for communicating with the IRM

Provides the initial support to create IPCPs via a command-line
tool. It extends the socket layer with a message that is sent over a
socket to the irmd when the irm_create_ipcp library function is called
from a program.

du_buff.c : Will now allocate memory only upon init, not upon create.
User can add compiler flag DU_BUFF_BLOCKSIZE to set the
size of a du_buff memory block. If the size for the
du_buff is larger than DU_BUFF_BLOCKSIZE, the du_buff will
be structured as follows:
HEAD -> DATA_BLOCK -> ... -> DATA_BLOCK -> TAIL
HEAD and TAIL are contiguous and may be larger than
DU_BUFF_BLOCKSIZE if required.
