build: Include tests in 'all' target

2025-11-07T07:36:20+00:00

When BUILD_TESTING=ON, then the default 'all' target will now build also the tests. This behaviour could be controlled by an extra variable (see https://stackoverflow.com/a/42235335), but this increases complexity without many benefits. Signed-off-by: Thijs Paelman Signed-off-by: Sander Vrijders

lib: Move encryption control from QoS to name

2025-09-10T06:21:58+00:00

This removes the flow encryption option (cypher_s) from the qosspec. The configuration file is configured in the security options (default /etc/ouroboros/security/). For this poc, encryption can be disabled client or server side by putting an enc.cfg file. If that file is present in the client folder, the client will require encryption. If that file is present on the server side, the server will require encryption and reject non-encrypted flows. Encryption is now configured outside of any application control. Example: /etc/ouroboros/security/client/oping/enc.cfg exists: irmd(II): Encryption enabled for oping. irmd(DB): File /etc/ouroboros/security/client/oping/crt.pem does not exist. irmd(II): No security info for oping. irmd(DB): Generated ephemeral keys for 87474. irmd/oap(PP): OAP_HDR [caf203681d997941 @ 2025-09-02 17:08:05 (UTC) ] --> irmd/oap(PP): Certificate: irmd/oap(PP): Ephemeral Public Key: [91 bytes] irmd/oap(PP): Data: irmd/oap(PP): Signature: Example: /etc/ouroboros/security/client/oping/enc.cfg does not exist: irmd(II): Allocating flow for 87506 to oping. irmd(DB): File /etc/ouroboros/security/client/oping/enc.cfg does not exist. irmd(DB): File /etc/ouroboros/security/client/oping/crt.pem does not exist. irmd(II): No security info for oping. irmd/oap(PP): OAP_HDR [e84bb9d7c3d9c002 @ 2025-09-02 17:08:30 (UTC) ] --> irmd/oap(PP): Certificate: irmd/oap(PP): Ephemeral Public Key: irmd/oap(PP): Data: irmd/oap(PP): Signature: Example: /etc/ouroboros/security/server/oping/enc.cfg exists: irmd(II): Flow request arrived for oping. irmd(DB): IPCP 88112 accepting flow 7 for oping. irmd(II): Encryption enabled for oping. irmd(DB): File /etc/ouroboros/security/server/oping/crt.pem does not exist. irmd(II): No security info for oping. irmd/oap(PP): OAP_HDR [3c717b3f31dff8df @ 2025-09-02 17:13:06 (UTC) ] <-- irmd/oap(PP): Certificate: irmd/oap(PP): Ephemeral Public Key: irmd/oap(PP): Data: irmd/oap(PP): Signature: irmd(WW): Encryption required but no key provided. The server side will pass the ECRYPT to the client: $ oping -l Ouroboros ping server started. Failed to accept flow: -1008 $ oping -n oping -c 1 Failed to allocate flow: -1008. Encryption on flows can now be changed at runtime without needing to touch/reconfigure/restart the process. Note: The ECRYPT result is passed on via the flow allocator responses through the IPCP (discovered/fixed some endianness issues), but the reason for rejecting the flow can be considered N+1 information... We may move that information up into the OAP header at some point. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Add flow authentication

2025-08-18T18:57:23+00:00

This adds initial implementation of peer authentication as part of flow allocation. If credentials are not provided, this will be accepted and logged as info that the flow is not authenticated. Certificates and keys are passed as .pem files. The key file should not be encrypted, else the IRMd will open a prompt for the password. The default location for these .pem files is in /etc/ouroboros/security. It is strongly recommended to make this directory only accessible to root. ├── security │ ├── cacert │ │ └── ca.root.o7s.crt.pem │ ├── client │ │ ├── │ │ | ├── crt.pem │ │ | └── key.pem │ │ └── | | ├──... | | │ ├── server │ │ ├── │ │ | ├── crt.pem │ │ | └── key.pem │ │ └── | | ├── ... | | │ └── untrusted │ └── sign.root.o7s.crt.pem Trusted root CA certificates go in the /cacert directory, untrusted certificates for signature verification go in the /untrusted directory. The IRMd will load these certificates at boot. The IRMd will look for certificates in the /client and /server directories. For each name a subdirectory can be added and the credentials in that directory are used to sign the OAP header for flows at flow_alloc() on the client side and flow_accept() on the server side. These defaults can be changed at build time using the following variables (in alphabetical order): OUROBOROS_CA_CRT_DIR /etc/ouroboros/security/cacert OUROBOROS_CLI_CRT_DIR /etc/ouroboros/security/client OUROBOROS_SECURITY_DIR /etc/ouroboros/security OUROBOROS_SRV_CRT_DIR /etc/ouroboros/security/server OUROBOROS_UNTRUSTED_DIR /etc/ouroboros/security/untrusted The directories for the names can also be configured at IRMd boot using the configuraton file and at runtime when a name is created using the "irm name create" CLI tool. The user needs to have permissions to access the keyfile and certificate when specifying the paths with the "irm name create" CLI tool. Signed-off-by: Dimitri Staessens

irmd: Initial Flow Allocation Protocol Header

2025-07-23T13:07:52+00:00

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

build: Fix tests with CMake >= 3.29

2024-04-16T12:16:16+00:00

Removing the testdriver source by the driver name doesn't work anymore in CMake 3.29 because of the following (breaking) change: Changed in version 3.29: The test driver source is listed by absolute path in the build tree. Previously it was listed only as . https://cmake.org/cmake/help/latest/command/create_test_sourcelist.html When using CMake 3.29 or above, Ouroboros will use the list POP_FRONT function (introduced in CMake 3.15) to get rid of it. https://cmake.org/cmake/help/latest/command/list.html#pop-front Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
