Fix missing set of api upon flow_alloc.
Various locking fixes.

This adds the functionality of exchanging the static DIF information
between 2 DIF members. After exchange the enrollment is stopped, and
the IPCP that initiated enrollment transitions to the enrolled state.

Sometimes the POSIX version was not set in source files. This caused
the compiler to not find the timespec struct, since we are using C89.
|
|
|

Blocking I/O now uses condition variables in the shared memory instead
of busy waiting. Timeouts can be specified. This requires the size of
the rbuffs and du_map to be the same, to guarantee that when the
shm_du_map is not full, the ap_rbuffs can't be full either.
Added the timeout option to the flow for future use.

This adds a flow_select() call that will sleep until an SDU can be
read on a flow. It returns the file descriptor for which an SDU is
ready. It takes as optional argument a timespec struct to specify a
timeout.

This provides the normal IPCP with bootstrapping and the initial steps
for enrollment. Next step is actually reacting to an enrollment
request and sending the data transfer constants.

Various portability fixes for FreeBSD. POSIX requires shm file names
to start with a "/" to be portable. lseek(2) can be undefined on
POSIX shm, replaced with ftruncate(2). IRMd check on existing lockfile
more portable.
FreeBSD 11.0 is preferred as it natively supports robust mutexes.
Full working LLC implementation pending.

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.

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 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.
Fixes #18.

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
Fixes #21.

The irm_create() function called irmd_destroy before some key values
were initialized.

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
sdu's for that application. Adds a function to clean the shm_du_map on
close.

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.

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

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.

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.

Update to POSIX 200112L to allow use of robust mutexes in the
shm_du_map. Removed the implementation of the rw_lock in favor of
pthread_rwlock_t.

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

|
|
|

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.

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.
Fixes #8.

The registration function has been moved to the irm tool, applications
now need to be registered by an administrator. Currently only supports
one instance per registered name, and an AP can be registered under
only one name.
The irmd can now start a registered server application on demand.
For the full functionality of the tool, execute "irm register".
AP name removed from flow allocation. Flow allocation does not send
the source ap name as it is quite useless. The accept() call now only
returns the AE name.

This introduces an IPC process that relays data between two local AP's
over the shm_du_map. Only configuration it has is a DIF name.
It required small modification elsewhere:
lib: added support for the IPCP_LOCAL type
irm: added support for the IPCP_LOCAL type
dif_config: added the IPCP_LOCAL type
tools: added support for the IPCP_LOCAL type

The cbr client will now use busy waiting by default to control the
sending rate. A --sleep option has been added to allow low CPU usage
when sending at low data rates. A --flood option has been added that
writes SDU's as fast as possible.

The fast path has been rewritten to have certainty to read the correct
flow. Deallocation will not release port_id's or fd's until they are
explicitly released locally.

dev.c: read now only reads an SDU if is is for the correct port_id
shm_ap_rbuff: added a function peek() that returns the port_id of the
tail.

Adds a missing modulo calculation that would result in index -1 being
returned instead of zero when the ringbuffer skipped back to the
beginning.
