* irmd: Always use reg_destroy_procDimitri Staessens2024-02-231-5/+5
| | | | | | | | | | | Destroying a process will now always be done with reg_destroy_proc, regardless of whether it was an IPCP or spawned. This makes it easier to keep the registry consistent and avoid races. Also improves some logs and updates some default settings.

* lib: Revise app flow allocationDimitri Staessens2024-02-231-4/+5
| | | | | | | | | | | | | This revises the application flow allocator to use the flow_info struct/message between the components. Revises the messaging to move the use protocol buffers to its own source (serdes-irm). Adds a timeout to the IRMd flow allocator to make sure flow allocations don't hang forever (this was previously taken care of by the sanitize thread).

* irmd: Revise IRMd internalsDimitri Staessens2024-02-191-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is a full revision of the IRMd internal implementation. The registry is now a proper subcomponent managing its own internal lock (a single mutex). Some tests are added for the registry and its data structures. Some macros for tests are added in <ouroboros/test.h>. Flow allocation is now more symmetric between the client side (alloc) and server size (accept). Each will create a flow in pending state (ALLOC_PENDING/ACCEPT_PENDING) that is potentially fulfilled by an IPCP using respond_alloc and respond_accept primitives. Deallocation is split in flow_dealloc (application side) and ipcp_flow_dealloc (IPCP side) to get the flow in DEALLOC_PENDING and DEALLOCATED state. Cleanup of failed flow allocation is now properly handled instead of relying on the sanitizer thread. The new sanitizer only needs to monitor crashed processes. On shutdown, the IRMd will now detect hanging processes and SIGKILL them and clean up their fuse mountpoints if needed. A lot of other things have been cleaned up and shuffled around a bit.

* irmd: Move registry objects to their own sourcesDimitri Staessens2023-03-211-4/+5
| | | | | | | | | | | | | | Rename internal data structures so it's clear that they are the IRMd representation of these objects for management purposes. Split functionality for these objects off and and move them to their own source files. Rename internal functions of the IRMd to reflect this, with some small refactoring.

* build: Fix TOML library variableDimitri Staessens2023-03-081-5/+6
| | | | | | | | LIBTOML_LIBRARIES should be explicitly set to "" if the TOML C99 library is not present. Signed-off-by: Dimitri Staessens <dimitri@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>
* irmd: Add configuration file supportDimitri Staessens2023-03-081-1/+36
| | | | | | | | | | | | | | | | | | | | | This adds initial support for configuration files using the C99 TOML parser (to be installed separately from https://github.com/cktan/tomlc99). The default location for the IRMd configuration file is /etc/ouroboros/irmd.conf. This is configurable at build time. An example file will be installed in the configuration directory with the name irmd.conf.example. Config file support can be disabled using the DISABLE_CONFIGFILE build option. There were some refactors and changes to the configuration messages and protobuf files. This works towards consolidation of protobuf C as an option for more generic handling of serialization/deserialization of various messages.

* ipcpd, irmd: Handle signal in main threadDimitri Staessens2018-10-181-2/+0
| | | | | | | | | The signals are now handled in the main thread instead of an asynchronous signal handler. The acceptloop is now correctly cancelled and the associated timeouts are removed.

* build: Update default values0.11.7Sander Vrijders2018-05-291-1/+1
| | | | | | | | | | | This sets updated default values for the default build. A higher connect timeout until we have asynchronous local IPC. Disabled SWIG since the lastest gcc reports an error. IPCP flow stats enabled by default since their impact on the performance is very limited. Waiting for the directory to enroll before returning to increase stability.

* build: Use GNUInstallDirs instead of hardcoded values0.9.9Sander Vrijders2018-02-061-1/+1
| | | | | | | | This changes the build to use GNUInstallDirs instead of hardcoded values. Package maintainers can then override these defaults by passing the correct value to cmake on the command line. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* lib, tools: Rename application process and instanceDimitri Staessens2017-12-021-2/+2
| | | | | | | | | | | This refactors ouroboros to use "program" instead of "application process" and "process" instead of "application process instance" to align with current naming in current Operating Systems courses instead of the ISO nomenclature adopted by RINA. This change permeates through the entire implementation. Also contains some minor other refactors.

* build: Add options for debug builds with sanitizerDimitri Staessens2017-11-141-2/+2
| | | | | | | | | This adds three build types, DebugASan, DebugTSan and DebugLSan that enable the Address, Thread and Leak Sanitizer by setting the fsanitize flag to the compiler. This option is supported by both gcc and clang. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* lib: Deprecate ouroboros_init and ourboros_finidimitri staessens2017-10-141-1/+1
| | | | | | | | | | | | | | 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.
* irmd: Add specific timeout for IPCP connectSander Vrijders2017-08-301-0/+2
| | | | | | This adds a specific timeout for IPCP connect, since it may take a lot longer than the regular socket timeout due to flow allocations in the IPCP.
* build: Revise the build systemdimitri staessens2017-08-211-0/+22
| | | | | | | | | | This revises the build system to have configuration per system component. System settings can now be set using cmake. The standard compliance defines were removed from configuration header and are set in the sources where needed. Also some small code refactors, such as moving the data for shims out of the ipcp structure to the respective shims were performed.
* build: Format CMakeLists.txt filesSander Vrijders2017-03-031-11/+11
| | | | The CMakeLists files are now properly indented.
* lib, ipcp: Revise fast path and flow interfacesdimitri staessens2016-10-041-0/+1
| | | | | | | | | | | | IPCPs can now use ap_init() to initialize the memory. All flows are accessed using flow descriptors, this greatly simplifies IPCP development. Reverts the fast path to a single ap_rbuff per process. Splits lib/ipcp into irmd/ipcp and lib/ipcp-dev. Adds a lib/shim-dev holding tailored functions for shims. Moves the buffer_t to utils.h. Fixes the shim-eth-llc length field. Removes the flow from shared.h. Fixes #4 Fixes #5
* irmd, lib: Rebuild the IRMd data modeldimitri staessens2016-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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.
* lib, irmd: Bind AP instances to AP_subsetsdimitri staessens2016-08-101-0/+1
| | | | | | | 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.
* irmd: Refactor and bugfixesdimitri staessens2016-08-081-0/+2
| | | | | | | Refactors the IRMd to extract reg_api and irm_flow structures to their own sources. Fixes some locking bugs.
* irmd: Move registry to its own sourcesdimitri staessens2016-07-051-0/+1
| | | | | All registry functionality has been extracted from the IRMd to improve modularity and legibility of the code.
* build: correct sandboxingdimitri staessens2016-06-271-1/+1
| | | | | paths cannot start with "/" or PREFIX will be omitted. PREFIX must be set before the project() call.
* build: Fix installation prefixSander Vrijders2016-06-271-1/+1
| | | | | | 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.
* build: Change install directories and set correct permissionsSander Vrijders2016-06-201-1/+1
| | | | | | | | | 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. Fixes #7
* irmd: Add wildcarding of DIF namesSander Vrijders2016-05-291-0/+1
| | | | | This adds wildcarding of DIF names so that application developers can for instance specify home.* to specify all home DIFs.
* build: Add check target, fix packagingSander Vrijders2016-03-071-1/+4
| | | | | | | | | 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.
* build: Move debugging switch to correct CMakeListsSander Vrijders2016-03-031-0/+5
| | | | | | 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.
* src: Rename daemons and add tools folderSander Vrijders2016-02-221-0/+16
This renames the daemons to end with a 'd', as is common for UNIX daemons. It also adds a tools folder, that will hold the tools of the Ouroboros prototype. Examples are a simple echo application, an application to instruct the IRM ...
