| | | | | | | | | | | | | | | | | | Removing the testdriver source by the driver name doesn't work anymore in CMake 3.29 because of the following (breaking) change: Changed in version 3.29: The test driver source is listed by absolute path in the build tree. Previously it was listed only as <driverName>. https://cmake.org/cmake/help/latest/command/create_test_sourcelist.html When using CMake 3.29 or above, Ouroboros will use the list POP_FRONT function (introduced in CMake 3.15) to get rid of it. https://cmake.org/cmake/help/latest/command/list.html#pop-front Signed-off-by: Dimitri Staessens <dimitri@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>

* lib: Rename CACEP to CEP and set conngmr timeout0.21.2Dimitri Staessens2024-02-269-73/+81
| | | | | | | | | | | | | | | | The Common Application Connection Establishment Protocol (CACEP) is a RINA construct associated with the Common Distributed Application Protocol (CDAP). We dropped CDAP as O7s sees connection establishment as common to all applications (though it can be a nop). The wiki already refers to this as (O7s) Connection Establishment Protocol (CEP). The connection manager will now timeout waiting for CEP messages to avoid hanging forever, configurable at build time via CONNMGR_RCV_TIMEOUT.

* irmd: Fix memleak on cancelDimitri Staessens2024-02-261-5/+12
| | | | | | | | | | | If the mainloop is cancelled during a write, the response buffer leaks.

* ipcpd: Mitigate race in wait_req_arr and wait_respDimitri Staessens2024-02-261-6/+15
| | | | | | | | | | | | | | | | | | | | The wait_flow_req_arr and wait_flow_resp functions are there to ensure the responses of the IRMd to flow allocation requests arrive in the correct order. These functions use a mutex: alloc_lock. After these functions return, the IPCP will switch to it's own (usually read-write) lock. In the local IPCP, this leaves room for a race where the state of the flow is accessed in alloc_resp before it is updated in wait_flow_req_arr. This race is only visible in the local IPCP, as the other IPCP have to send information between these calls, but it is theoretically possible when using any IPCP for local IPC. In the ipcpd-local, it happens ~0.01% to ~0.03% of flow allocations. This mitigates the problem in the ipcpd-local by adding a 1ms wait to the flow allocation if this race is detected.

* irmd: Fix flow deallocation timeoutDimitri Staessens2024-02-262-8/+15

* irmd: Always use reg_destroy_procDimitri Staessens2024-02-237-126/+95
| | | | | | | | | | | 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.

Revises the messaging to move the use protocol buffers to its own source (serdes-irm).

* irmd: Revise IRMd internalsDimitri Staessens2024-02-1959-3248/+6962
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | Error instead of warn when the --config param is set, but the file is not found. This prevents the IRMd from being in a 'half state', where it is started, but the expected config is not applied. One simply has to remove the --config option OR supply a correct filepath.

* irmd: Fix parsing empty argument in configfileThijs Paelman2024-01-131-1/+1
| | | | | | | | | | | | | | Previously, args=[""] would crash the IRMd when it tried to auto-instantiate the program. Now, specifying an empty string as argument to a program WILL automatically start that program if there is an incoming flow, but without any arguments, as intended. Remark: The semantics might be a bit less clear than e.g. args=["--listen"], but they are a natural extension.

* irmd: Fix parsing multiple args in configfileThijs Paelman2023-12-311-9/+11
| | | | | | | | | | | | | | | | | New method retains the original string in parsing the args string into an argv dynamic array. Previous method (`strtok`) didn't work, because it is a destructive function, changing the supplied string. We however needed to apply it twice to the same string. It is still done twice in a loop, to make sure argc is exact. Other methods, like counting the amount of spaces to determine argc, would be incorrect for his particular way of tokenizing if arguments are separated by e.g. two spaces. Also fixes a wrong pointer dereference, which did go unnoticed before due to the previous error.

* lib: Move public key handling from app to IRMdDimitri Staessens2023-12-174-125/+188
| | | | | | | | | | | | | | | The application was generating its public keypair for its ECDHE key exchange. This is now done by the IRMd, which will check the requested qosspec and then apply what is needed. The flow_alloc and flow_accept calls will just return the symmetric key to the application. This makes it easier when we add configurations with given public key pairs and other encryption algorithms, which can then all be configured globally in the IRMd instead of having all the options replicated and implemented in each and every application.

* lib: Fix reading FUSE output on RaspbianDimitri Staessens2023-11-262-8/+17
| | | | | | | | | | | | | | | | | The previous patch only fixed listing the contents on the fuse filesystem. Apparently files with st_blocks = 0 as seen as empty on Raspbian, and the FUSE read() function isn't invoked for such files. Setting st_blocks to 1 fixes that, but st_blksize is ignored for fuse. So, on raspbian the filesize is now a huge number, but at least reading the fuse filesystem works. Corrected the filesystem attributes for the IPCP output for systems that don't rely on st_blocks to assess filesize. Also set the file mode to 0644 as these are not executables.
