irmd: Fix wrong hash length when getting ipcpd

2024-02-26T07:59:15Z

The get_ipcpd_by_dst function was returning the hash length of the last IPCP in the list instead of the length of the actual hash. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Always use reg_destroy_proc

2024-02-23T15:41:38Z

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. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

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: Store IPCP name and type in info struct

2023-11-29T08:57:29Z

The information for an IPCP is now stored in an ipcp_info struct, containing name and type. The IRM public API is not changed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

include: Rename layer.layer_name to layer.name

2023-11-29T08:57:29Z

The layer_info had a member layer_name which is a bit redundant. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Use CMAKE_INSTALL_SBINDIR to spawn IPCPs

2023-04-03T06:35:49Z

The "/sbin/" was hard-coded, which will fail if the installation SBIN directory is configured to something else. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Use buffer_t for piggybacked data

2023-03-18T16:12:27Z

Instead of passing a const void * and len, it now passes buffer_t to operations that send piggybacked data (flow_req_arr and flow_reply) and a buffer_t * for operations that send and receive piggybacked data (flow_alloc and flow_accept).

irmd: Add configuration file support

2023-03-08T14:59:37Z

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.
