* ipcpd: Update DHT for unicast layerDimitri Staessens2 days26-2220/+5289
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <search factor> (default: 3)] [dht_k <replication factor> (default: 8)] [dht_t_expire <expiration (s)> (default: 86400)] [dht_t_refresh <contact refresh (s)> (default: 900)] [dht_t_replicate <replication (s)> (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.

* lib: Fix flow timeouts after flow allocationDimitri Staessens2 days1-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | There were two timeout bugs in the flow allocation steps. Found these when debugging why some links were always timing out in one direction. The first bug only affects flows going through the connection manager in the IPCP (such as the management flow used by the link state routing component. The connection manager was setting a timeout on the flow for its handling connection establishment, but didn't reset that timeout before handing the flow to the internal component after the CEP was complete. The link-state routing component was showing flow read timeouts (ETIMEDOUT) without setting one. This was not causing the links to time out. The second one was that the IPCP was keeping the qosspec from on the np1 flow, which, when the qosspec requested for the applicatoin had a keepalive set, would always time out. This bug was the root cause for some link advertisements not to be read and links to time out in the link-state routing component.

* irmd: Initial Flow Allocation Protocol HeaderDimitri Staessens2025-07-235-13/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the initial version for the flow allocation protocol header between IRMd instances. This is a step towards flow authentication. The header supports secure and authenticated flow allocation, supporting certificate-based authentication and ephemeral key exchange for end-to-end encryption. id: 128-bit identifier for the entity. timestamp: 64-bit timestamp (replay protection). certificate: Certificate for authentication. public key: ECDHE public key for key exchange. data: Application data. signature: Signature for integrity/authenticity. Authentication and encryption require OpenSSL to be installed. The IRMd compares the allocation request delay with the MPL of the Layer over which the flow allocation was sent. MPL is now reported by the Layer in ms instead of seconds. Time functions revised for consistency and adds some tests. The TPM can now print thread running times in Debug builds (TPM_DEBUG_REPORT_INTERVAL) and abort processes with hung threads (TPM_DEBUG_ABORT_TIMEOUT). Long running threads waiting for input should call tpm_wait_work() to avoid trigger a process abort.

* lib: Rename CACEP to CEP and set conngmr timeout0.21.2Dimitri Staessens2024-02-265-31/+45
| | | | | | | | | | | | | | | | The Common Application Connection Establishment Protocol (CACEP) is a RINA construct associated with the Common Distributed Application Protocol (CDAP). We dropped CDAP as O7s sees connection establishment as common to all applications (though it can be a nop). The wiki already refers to this as (O7s) Connection Establishment Protocol (CEP). The connection manager will now timeout waiting for CEP messages to avoid hanging forever, configurable at build time via CONNMGR_RCV_TIMEOUT.

* ipcpd: Mitigate race in wait_req_arr and wait_respDimitri Staessens2024-02-261-6/+15
| | | | | | | | | | | | | | | | | | | | The wait_flow_req_arr and wait_flow_resp functions are there to ensure the responses of the IRMd to flow allocation requests arrive in the correct order. These functions use a mutex: alloc_lock. After these functions return, the IPCP will switch to it's own (usually read-write) lock. In the local IPCP, this leaves room for a race where the state of the flow is accessed in alloc_resp before it is updated in wait_flow_req_arr. This race is only visible in the local IPCP, as the other IPCP have to send information between these calls, but it is theoretically possible when using any IPCP for local IPC. In the ipcpd-local, it happens ~0.01% to ~0.03% of flow allocations. This mitigates the problem in the ipcpd-local by adding a 1ms wait to the flow allocation if this race is detected.

* irmd: Revise IRMd internalsDimitri Staessens2024-02-1911-71/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <ouroboros/test.h>. 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 reading FUSE output on RaspbianDimitri Staessens2023-11-261-2/+6
| | | | | | | | | | | | | | | | | The previous patch only fixed listing the contents on the fuse filesystem. Apparently files with st_blocks = 0 as seen as empty on Raspbian, and the FUSE read() function isn't invoked for such files. Setting st_blocks to 1 fixes that, but st_blksize is ignored for fuse. So, on raspbian the filesize is now a huge number, but at least reading the fuse filesystem works. Corrected the filesystem attributes for the IPCP output for systems that don't rely on st_blocks to assess filesize. Also set the file mode to 0644 as these are not executables.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The common enrollment code between the unicast and broadcast IPCP included the same C source from a source file in the unicast and broadcast directories. Now it's handled by defining COMMON_SOURCES for the unicast and broadcast IPCP. For now, only the enrollment component is common. Two things are needed for the connection manager: * Routing to be fixed to use a supporting broadcast layer. Then management flows can be removed from the unicast IPCP (as they are in fact data transfer flows of the broadcast layer that supports the routing dissemination traffic). * DHT to enroll as part of IPCP enrollment. Now it enrolls when a data transfer flow is established to be more akin to how Kademlia nodes join a Kademlia DHT, but this should be revised to adhere more to O7s enrollment concepts. After that, the connection manager code will also be completely shared between the unicast and broadcast layer and the connmgr will also be common code.
