irmd: Fix bad merge in reg.c

2026-02-22T17:33:20+00:00

A merge conflict was left unresolved, resulting in compilation errors. Signed-off-by: Sander Vrijders Signed-off-by: Dimitri Staessens

irmd: Fix memleak in reg tests

2026-02-22T15:06:49+00:00

Call freebuf(pbuf) before returning from each test thread function. Since clrbuf zeroes pbuf.data to NULL on the success path, free(NULL) is safe. On the failure path of reg_respond_*, it now properly frees the still-allocated data. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Skip vertices with empty forwarding lists

2026-02-22T15:05:00+00:00

Fixes ECMP routing table to skip unreachable vertices with empty forwarding lists, avoiding uninitialized nhop access. Replace inner vertex list walk with bounded index loop instead of using a list_for_each to track indices (which confuses the static analyzer as it seems it can't prove the index remains valid). Remove spurious free(*dist) on ECMP success path (caller frees). Extract edge cleanup into free_edges helper in del_vertex to avoid a static analyzer false positive.

lib: Fix ssm pool double free

2026-02-22T15:04:31+00:00

Remove double-free in ssm_pool_destroy — ssm_pool_close already frees the pool. The pool sharding test had a free spbs/ptrs on partial malloc failure. Now initializes children array to -1 to prevent reading uninitialized values. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix invalid malloc pointer type

2026-02-22T15:04:24+00:00

The static analyzer complained about the struct in6_addr malloc being converted to uint8_t *. Fixed by casting IN6_LEN to a size_t numeric value instead of the direct sizeof. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix unused values in unicast IPCP

2026-02-22T15:04:16+00:00

Use the key in the store operation in the DHT, to avoid static analyzer seeing it as being set without being used in release builds. The length of the packet buffer is only used when tracking DT stats, so should be set within the IPCP_FLOW_STATS guard. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Allow direct rbuff between local processes

2026-02-22T15:02:16+00:00

This allows bypassing the IPCP for local processes that share the same packet pool, lowering latency between processes to comparable levels as Unix sockets (RTT in the order of a microsecond). For local processes, no IPCPs are needed: $ irm b prog oping n oping $ oping -l Ouroboros ping server started. New flow 64. Received 64 bytes on fd 64. The direct IPC can be disabled with the DISABLE_DIRECT_IPC build flag. Note that this is needed for rumba 'local' experiments to emulate network topologies. Without this flag all processes will just communicate directly. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Add git hash to version string

2026-02-18T07:02:16+00:00

Embed git commit hash into version.h and irmd --version output using git describe. Regenerated at build time to stay current across commits. Ouroboros version MAJOR.MINOR.PATCH (TAG-COMMITS-GHASH-dirty) Example for dirty work tree (uncommitted changes): $ irmd --version Ouroboros version 0.22.0 (0.22.0-36-g86dba544-dirty) Example after commit: $ sudo irmd --version Ouroboros version 0.22.0-37-g55fa9445 Officical release (on tag): Ouroboros version 0.22.0 Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Fix lsdb being renamed to lspb

2026-02-18T07:00:14+00:00

A recent bulk rename of sdb -> spb (shm du buff to shm pkt buff) unintentionally renamed the lsdb. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

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
