When an application closes the shm_du_map, it will clean all remaining
sdu's for that application. Adds a function to clean the shm_du_map on
close.

The irmd will now collect terminated child processes (autostarted
api's and ipcpd's). Upon exit, all autostarted api's will be killed.

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.
Fixes #16.

All registry functionality has been extracted from the IRMd to improve
modularity and legibility of the code.

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.

When empty, gpb does not send a message. Functions that return null
will now send a message with return value set to -1.

The bind tool and the auto_execute function will check if the binary
exists and is executable.
Return value of auto_execute corrected to pid_t

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.

This changes the IRM API after discussions with Dimitri. The register
operation is now split into a bind and register operation. The same
for unregister; unbind and unregister. PIDs are now used as the
application instance name. A name for a PID is only provided for
scriptability in bash. It is therefore also no longer passed down to
the IPCP. Every operation on an IPCP through the IRM API has to use
the PID. Quering of the PIDs by name is possible. The IRM tool has
been updated to use this new API as well. A subcommand 'ipcp' has been
added for operations that take effect on IPCPs only.
Fixes #12

build: Fix installation prefix
|
| |
| |
| |

The installation prefix was taking a trailing backslash, while it is
common not to do so. Fixed it so that any trailing backslash is
removed by the compilation and installation scripts.

IPCP destruction was erroneously removed. This has been fixed.
Autostart of application is fixed, it would trigger even with an
instance waiting for flows. Moved SIGPIPE handler to the top to allow
shutting down the IRMD when running with valgrind (which triggers
SIGPIPE).

Functionality that was previously thought to be part of the DIF
Allocator is actually namespace management. Hence the file has been
renamed and the API updated.

This removes any implementation specific error numbers. Only errors
that are implementation independent should be returned.

This adds error numbers specificly for Ouroboros. It also refactors
some of the header files that are installed.

Update to POSIX 200112L to allow use of robust mutexes in the

Reverting from previous commit. Even when running Ouroboros sandboxed,
the sockets and shared memory should be created in the default system
paths.

ipcpd: Adds RX_RING and TX_RING in shim-eth-llc
|
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
This adds the RX_RING and TX_RING socket options to the shim-eth-llc
for faster transmission and reception. On systems where these options
are not available the old method of sending and receiving is
used. Further optimization would be creating and assigning a
read/write thread per CPU core, but that becomes very platform
specific, and is not required in the short term.

This sets the correct install directories for all the binaries,
library and header files. It also sets the right permissions on the
sockets and shared memory so that regular users can also use the
ouroboros library. Root privileges are required to run the irmd.

If an IPCP dies, the IRMd will remove the stale resources.

Port_id's on pending flows that time out are now released. Flows that
are stale because one of the parent processes exited are removed.

Added the pid of the irmd to the shm_du_map. The IRMd will check for
an existing shm_du_map. If there is an existing file, it will exit if
the owner IRMd is running or remove it if the owner IRMd is not
running.
Also simplifies calculation of the shm_du_map pointers and corrects
exiting calls for the IRMd.
