lib: Rename CACEP to CEP and set conngmr timeout

2024-02-26T08:00:09Z

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.

lib: Revise app flow allocation

2024-02-23T15:41:37Z

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 internals

2024-02-19T10:49:07Z

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 . 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.

include: Use common definition between lib and IRMd

2024-01-31T09:27:56Z

Some definitions/enums were different between the library and IRMd (flow_state, ipcp_state). This moves them to common ground. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Fix passing symmetric key on allocation

2023-12-31T15:47:55Z

The check if the flow requires a key in irmd flow_alloc was missing when setting the pointers for the piggyback data, so non-encrypted flow allocations failed on irm_msg__pack(). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix wrong fccntl return for FLOWGRCVTIMEO

2023-12-17T12:25:06Z

The send timeout was returned instead of the receive timeout. Signed-off-by: Thijs Paelman Signed-off-by: Sander Vrijders

lib: Move public key handling from app to IRMd

2023-12-17T12:23:49Z

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: Add newlines to stderr output at init

The stderr lines had no newline. Fixed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix timeout overflow on 32-bit systems

2023-11-08T08:17:53Z

The timeout comparison for keepalives could overflow on 32-bit systems, as times were converted to nanoseconds and be limited to a bit over 4 seconds. This caused flow reads to fail miserably with EFLOWPEER errors when keepalives were set higher on these systems. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
