This simplifies the echo-app tool implementation to a single source
file since it's meant to be a small example application.

This commit deprecates ouroboros_init and ouroboros_fini and adds them
as a constructor or destructor, causing these function to be run
automatically when a program that links to the library calls and exits
main(). For this to fully work, the library had to be split so that we
can avoid the irmd calling these functions (the IRMd has to create the
shm structures on which these calls depend).
The library is split in 3 parts: libouroboros-dev, libouroboros-irm
and libouroboros-common. The latter is linked to the other two so that
including libouroboros-dev or libouroboros-irm will also link
libouroboros-common.

Fixes #35

The flow_alloc_res and flow_alloc_resp calls have been removed. The
flow_alloc and flow_accept calls are now both blocking and take an
additional timeout argument.

Our mailserver was migrated from intec.ugent.be to the central
ugent.be emailserver. This PR updates the header files to reflect this
change as well. Some header files were also homogenized if the
parameters within the functions were badly aligned.
|
|
|
|

The CMakeLists files are now properly indented.

The AE name should not be passed over the layer boundaries. If an
application has more than one AE it should exchange this in CACEP.

This corrects the license statements on all files. Installed headers

Receiver timeouts can now be set on a flow using the flow_set_timeout
function. Specifying NULL disables the timeout. The flow_get_timeout
function gets the value for the timeout.
This commit also deprecates fcntl in favor of flow_get_flags and
flow_set_flags functions.
struct qos_spec is typedef'd as a qosspec_t.
The tools and cdap.c are updated to use the new API.
Fixes a bug in operf client where the client's writer thread wouldn't
cancel on SIGINT.

This has the code checked with -Wcast-qual and -Wconversion flags.
These flags were removed because SWIG generated code fails.
|
|
|
|
|
| |
This reduces the risk for some bugs, for instance due to
signed/unsigned mismatches and unused variables.

The complete data model inside the IRMd has been restructured. The
bind operation was revised to allow binding of AP and AP instances and
register those names with different DIFs (see "irm bind" for details).
Server applications require to call ap_init with a server name
argument, client application that do not the be reachable over any DIF
can call ap_init(NULL). Calling ap_init for a client with a specified
name will not have adverse consequences for the application, but will
consume unnecessary resources in the IRMd.
Application servers can now be started at any point after the IRMd has
been started. Starting servers, binding AP names and registering names in
DIFs can be performed in any order that does not defy temporal logic.
Supports naming instances by their pid. In case of IPCP Instances
created with the IRM tool, the name assigned during "irm ipcp create"
can be used.
All the changes required updates in the tools.

This call will allow grouping AP instances of a certain AP together
which are configured identically. Adds the bind operation to dev and
updates the applications to make use of this call. Flow_alloc is now
only called with the pid and doesn't send the apn anymore.

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.

paths cannot start with "/" or PREFIX will be omitted. PREFIX must be
set before the project() call.
|
|
|
|
|
|

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.

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.

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 fixes bad indentation and log messages without a newline in the
echo application.

This commit has a first implementation of flow allocation (the "slow
path") and read/write (the "fast path") for ouroboros. It provides
basic but unstable communications over the shared memory.
It required a lot of changes all over the stack, and fixes a number of
previously undetected issues.
This PR still need heavy revision regarding data model, locking and
cleanup.
lib/dev: modifications to the API. It now uses an ap_init() call to
set the AP name and sets the Instance ID to the pid of the process. It
also binds the AP to the shared memory and creates tables for mappings
in the fast path. A call to ap_fini() releases the resources.
lib/shm_ap_rbuff: added ring buffer for data exchange between
processes in the fast path. It passes an index in the shm_du_map.
lib/shm_du_map: rewrote API to work with calls from dev.c. Garbage
collector added. Tests updated to new API.
ipcpd/ipcp-data: removed everything related to flows, as these are
universal for all ap's and kept in ap_data (dev.c), or similar structs
for shim ipcps.
shim-udp: added flow allocator and read/write functions and shm
elements.
irmd: revised data model and structures necessary for flow allocation.
tools: echo updated to new dev.h API.
messaging system was updated to comply with new flow allocation
messages. All exchanges use pid and port_id to bootstrap the fast
path.

Initial code for application registration. Specifying "*" will (for
now) register with the first IPCP available in the system. Modified
the echo server not to barf messages on failed accept()

all functions taking a char * ap_name and uint id now take either a
instance_name_t or instance_name_t *

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.
|
|
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.
