lib: Add struct llist for lists tracking len

2026-02-18T06:58:21+00:00

The DHT uses a struct {struct list_head, size_t len} pattern, which is also useful in the registry and other places. Having a struct llist (defined in list.h) with consistent macros for addition/deletion etc removes a lot of duplication and boilerplate and reduces the risk of inconsistent updates. The list management is now a macro-only implementation. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Fix invisible IPCP_TARGET variables

2026-02-13T08:22:29+00:00

The IPCP_*_TARGET variables (e.g., set(IPCP_LOCAL_TARGET ipcpd-local)) were defined locally in each IPCP's CMakeLists.txt (e.g., CMakeLists.txt), but the configure_file() that substitutes @IPCP_LOCAL_TARGET@ into config.h.in runs in a sibling scope that is processed before ipcpd. Since CMake variables don't propagate between sibling directory scopes, all @IPCP_*_TARGET@ substituted to empty strings, resulting in IPCP_LOCAL_EXEC "". Moved the IPCP_*_TARGET definitions into the cmake/config/ipcp/*.cmake files so they are known when generating config.h. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Refactor CMake back to in-tree CMakeLists

2026-02-13T08:22:29+00:00

This moves the build definitions back to src/ subdirectories (CMakeLists.txt per component). Configuration and dependencies are kept out of tree. Configuration options are bundled into cmake/config/ modules. Dependencies are grouped by component (system/, crypt/, eth/, coverage/, etc.). It now consistently uses target-based commands (target_include_directories, target_link_libraries) instead of global include_directories(). Proper PRIVATE/PUBLIC visibility for executable link libraries. CONFIG_OUROBOROS_DEBUG now properly set based on being a valid debug config (not just checking the string name). It also adds OuroborosTargets export for find_package() support and CMake package config files (OuroborosConfig.cmake) for easier integration with CMake projects. The build logic now follows more idiomatic CMake practices with configuration separated from target definitions. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Refactor CMake modules

2026-01-07T09:00:06+00:00

This moves the CMake build logic out of the source tree and splits it up into a more modular form. The tests now have a CMakeLists.txt file in their respective source directory. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Fix the flow_join operation

2025-09-24T06:06:47+00:00

This fixes a regression in the code path for joining a broadcast Layer. It deprecates the qos parameter on flow_join, as the QoS is implied by the broadcast Layer itself. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Update DHT for unicast layer

2025-08-06T10:34:15+00:00

This is a rewrite of the DHT for name-to-address resolution in the unicast layer. It is now integrated as a proper directory policy. The dir_wait_running function is removed, instead the a DHT peer is passed on during IPCP enrolment. Each DHT request/response gets a random 64-bit ID ('cookie'). DHT messages to the same peer are deduped, except in the case when the DHT is low on contacts. In that case, it will contact the per it received at enrolment for more contacts. To combat packet loss, these messages are not deduped by means of a 'magic cookie', chosen at random when the DHT starts. The DHT parameters (Kademlia) can be set using the configfile or the IRM command line tools: if DIRECTORY_POLICY == DHT [dht_alpha (default: 3)] [dht_k (default: 8)] [dht_t_expire (default: 86400)] [dht_t_refresh (default: 900)] [dht_t_replicate (default: 900)] This commit also adds support for a protocol debug level (PP). Protocol debugging for the DHT can be enabled using the DEBUG_PROTO_DHT build flag. The DHT has the following message types: DHT_STORE, sent to k peers. Not acknowledged. DHT_STORE --> [2861814146dbf9b5|ed:d9:e2:c4]. key: bcc236ab6ec69e65 [32 bytes] val: 00000000c4e2d9ed [8 bytes] exp: 2025-08-03 17:29:44 (UTC). DHT_FIND_NODE_REQ, sent to 'alpha' peers, with a corresponding response. This is used to update the peer routing table to iteratively look for the nodes with IDs closest to the requested key. DHT_FIND_NODE_REQ --> [a62f92abffb451c4|ed:d9:e2:c4]. cookie: 2d4b7acef8308210 key: a62f92abffb451c4 [32 bytes] DHT_FIND_NODE_RSP <-- [2861814146dbf9b5|ed:d9:e2:c4]. cookie: 2d4b7acef8308210 key: a62f92abffb451c4 [32 bytes] contacts: [1] [a62f92abffb451c4|9f:0d:c1:fb] DHT_FIND_VALUE_REQ, sent to 'k' peers, with a corresponding response.

lib: Swap len and data in the buffer_t

2025-07-25T14:24:46+00:00

This is how the ProtoBufCBinary data type is defined, so it will allow easier conversion until we get rid of it. But it makes sense, as the size_t will always be aligned. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Refactor ipcp main struct

2025-07-23T13:07:59+00:00

The ipcpi (IPCP instance) is now cleanly tucked away within its source file instead of exposed all over the place. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Revise app flow allocation

2024-02-23T15:41:37+00:00

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).
