lib: Remove the not-so lockless rbuff_ll

2026-01-07T13:33:39+00:00

The "lockless" rbuff was mixing paradigms as it still has mutexes and condvars to avoid spinning on blocking behaviour. This was a bad idea. We'll add proper lockless implementations later. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Revise IRMd internals

2024-02-19T10:49:07+00:00

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: Wrap pthread_cond_timedwait for NULL abstime

2023-10-25T07:53:27+00:00

We often have the pattern where we NULL-check abstime for pthread_cond_timedwait to call pthread_cond_wait if it is. Added a __timedwait function to wrap this. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Add rbuff support for FLOWPEER state

2022-03-30T13:05:05+00:00

This allows setting the FLOWPEER state on a flow to signal a peer is unresponsive. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Flag all flows down as the IRMd exits

2022-03-03T11:05:57+00:00

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: Handle FLOWDOWN during blocking read

2022-02-21T08:05:27+00:00

The blocking read from the rbuff was not correctly handling flow down states, returning a valid index. The attempt to fetch the header then failed on an assertion. The blocking read will now return -EFLOWDOWN if the flow is marked down by the IPCP. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib, ipcpd, irmd: Wrap pthread unlocks for cleanup

2021-06-23T06:36:48+00:00

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
