Upon receipt of a frame, the minimum of the length reported in the
frame and the frame length reported by kernel is taken. Some device
drivers change the length in the frame. Some others add padding,
making the length reported by the kernel too high. This is a lousy
workaround to make it work on as many systems as possible.

It was missing the FLOW_PENDING state. All states that are not
FLOW_ALLOCATED should return -1. This is now fixed.

When a pending accept is shutdown on irmd exit, there are no more
threads running, but it should also change the state to NULL. This is
now correctly handled in the cleanup of the cancellation point.
Also fixed a busy wait with a condition variable.

irmd: Revised flow allocation
|
| |/
| |
| |
| |
| |
| |
| |
| |
| | |
Flow allocation requests and registered api states revised so all
states are tracked with a condition variable. This is a more reliable
approach and improves stability of flow allocation.
Some other refactoring was also done, such as renaming port_map_entry
to irm_flow and hiding some internal structures of the registry.

The protobuf include directory was not being correctly handed to the
compiler when building. Now the include directory is added
project-wide. And the protobuf package is searched for only once.

ipcpd: normal: Add main loop to normal IPCP
|
| |
| |
| |
| |
| |
| | |
This adds the main loop to the normal IPCP, just like it is present in
the shim IPCPs. So in essence, the normal IPCP now reacts to all
operations from ipcp.h.

The destroy now only frees after all threads stopped using the object.
Also fixes a SEGV when trying to allocate a flow to a remote name.

ipcpd: normal: Establish N-1 management flows
|

This adds the intial implementation of establishing management N-1
flows between normal IPCPs. On calling fmgr_mgmt_flow, a management
flow will be setup to a certain destination IPCP. After flow
allocation, the fd is handed to the RIB manager. The flow manager also
listens for incoming flow requests. In case they are management flows,
they are handed to the RIB manager, otherwise to the FRCT.

This adds the initial headers for the normal IPCP. The normal IPCP
consists of 3 main components:
* The flow manager, in charge of managing N and N-1 flows.
* The RIB manager, in charge of managing the RIB
* FRCT: The flow and retransmission control task

This removes the parameter N-1 DIF from the enroll operation. IPCPs
should just allocate a flow to a DIF name and let the N-1 DIF resolve
it.

Correct implementation of allocation for the Protocol Control
Information. Also removes stale code checking for a corner case when
the du map still wrapped multi-block SDU's.

Easier names for the functions.The registry now uses a single list to
keep track of applications (bindings), moved the auto_exec state per
binding.

For locally registered processes, the IRMd will first look for the
local, then the normal, then the shim-udp. It will look for a normal,
a shim-eth-llc and ultimately a shim-udp for non-local destinations.
It does not yet check if a remote destination is actually known in a
DIF.

All includes of <errno.h> within ouroboros are replaced with the
ouroboros errno.

The pid of the IRMd is stored in a lockfile in shared memory. This
makes checking if the IRMd is running independent of the
configuration, as previously the IRMd pid was stored at the end of the
shm_du_map, which could not be read by an IRMd that would be compiled
with different configuration options.
Also corrects some unnecessary includes

lib:irmd: Fix logs and irm_create
|

IRMd and ipcps will now close the logfile upon exit.
Also corrects exit(1) to exit(EXIT_FAILURE) and exit(0) to
exit(EXIT_SUCCESS).

The irm_create() function called irmd_destroy before some key values
were initialized.
Logs cleanup was missing.

Added check if the owner of the du map is actually running so a new
IRMd instance can remove a stale DU map.

Writing output to log files is now enabled by default. Logs are
written to <INSTALL_PREFIX>/var/log/ouroboros, which is created on
install. There is a log file for the irmd and one per IPCP. To still
get (colored) output on stdout, provide the --stdout switch when
starting the irmd.

When an application closes the shm_du_map, it will clean all remaining

close.

Reflects that the functions (dis)associate an application instance
from/with a name and not remove it from the registry entirely.

The stack used pid 0 (the scheduler) to indicate an invalid process
instance, probably as a leftover from the deprecated application
process instance id. Using -1 is a better solution.

lib: Provide first implementation of revised CDAP
|
| |

This commit fixes some errors reported during compilation that were
undiscovered by my gcc compiler but found by clang, and errors not
found on my system but found by the CI platform.

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.

When introducing robust mutexes, ouroboros moved to POSIX 200809L
which includes the strdup function in <string.h>. Including
<ouroboros/config.h> will give access to strdup.

The bind function will search all directories specified in the PATH
variable for the ap fed to the irm bind command and check if it is
executable by the uid executing irm bind command.
Adds missing info logs for the bind/unbind and unreg operations in the
irmd.

This will make the library check if the user has permissions to
execute the binary when auto is set. This prevents writing malicious
software that would use the irmd to execute other applications to
which the user has no access.

This PR enhances the shared memory providing recovery if a process
crashes. It adds a SHM_DU_TIMEOUT_MICROS variable, setting an
expiration time for SDU's when shared memory is full. If an
application doesn't read a blocking SDU within this time, the shared
memory will be cleansed of all SDU's for this application and the
application's rbuff will be cleared.
Some refactoring of the API's. Fixed wrong pthread checks in IRMd.
