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.

lib: Fix lengths of shared memory objects

Seems like all shared memory objects were truncated to a size that came up a byte short. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Flag all flows down as the IRMd exits

2022-03-03T11:05:57Z

On exit of the IRMd all flows will now be flagged as down, so external applications will not hang anymore. Note: reads keep work from flows that are down until there are no more remaining packets in the buffer, but no more packets can be written. When the RIB is used, the external application may exit a bit later than the IRMd, so I added a brief sleep before the IRMd tries to remove the fuse main directory.

lib, ipcpd, irmd: Wrap pthread unlocks for cleanup

2021-06-23T06:36:48Z

This add an ouroboros/pthread.h header that wraps the pthread_..._unlock() functions for cleanup using pthread_cleanup_push() as this casting is not safe (and there were definitely bad casts in the code). The close() function is now also wrapped for cleanup in ouroboros/sockets.h. This allows enabling more compiler checks. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
