* irmd: Use long-form options in config filesThijs Paelman2023-12-171-2/+3
| | | | | | | | | Since config files are meant to be read, use long-form arguments where possible. Also fixed autostart behaviour for oecho. Signed-off-by: Thijs Paelman <thijs@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>
* lib: Move public key handling from app to IRMdDimitri Staessens2023-12-174-125/+188
| | | | | | | | | | | | | | | The application was generating its public keypair for its ECDHE key exchange. This is now done by the IRMd, which will check the requested qosspec and then apply what is needed. The flow_alloc and flow_accept calls will just return the symmetric key to the application. This makes it easier when we add configurations with given public key pairs and other encryption algorithms, which can then all be configured globally in the IRMd instead of having all the options replicated and implemented in each and every application.

* irmd: Don't log an error when server quitsDimitri Staessens2023-11-301-2/+7
| | | | | | | | | | The revision of the IRMd caused it to log an error when an application terminates and closes the unix socket (EPIPE) or the IRMd shutds down (EIRMD). These are expected and correct behaviour. Replaced the error logs with debug logs. Signed-off-by: Dimitri Staessens <dimitri@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>

* ipcpd: Fix eth management packets blocking rdrbuff0.20.3Dimitri Staessens2023-11-263-21/+20
| | | | | | | | | | The ipcpd-eth-* reserve a packet buffer slot for the N+1 data packets whenever receiving a frame. For management frames, that slot is not needed and it was not released, thus blocking the rdrbuff.

* lib: Fix reading FUSE output on RaspbianDimitri Staessens2023-11-262-8/+17
| | | | | | | | | | | | | | | | | 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.

* lib: Fix FUSE output on RaspbianDimitri Staessens2023-11-202-1/+5
| | | | | | | | | | | | For some reason, 'ls' on raspbian invoked the fuse readdir() in a loop where the first call had fuse_file_info * info set to NULL and subsequent calls had info->nonseekable set to 1. Since we don't check the value the info struct, this caused an infinite loop when trying to list the contents of the fuse filesystem subdirectories of /tmp/ouroboros/.

| | | | | | | | | | The timeout comparison for keepalives could overflow on 32-bit systems, as times were converted to nanoseconds and be limited to a bit over 4 seconds. This caused flow reads to fail miserably with EFLOWPEER errors when keepalives were set higher on these systems.

| | | | | | | | | | The irmd was automatically loading the default configfile (usually /etc/ouroboros/irmd.conf) if present. Now the --config parameter has to be set for the irmd to load a config.

* irmd: Remove separate rwlock for flowsDimitri Staessens2023-10-251-62/+36
| | | | | | | | | | Modifications for flows were made under a different rwlock (flows_lock) than the rwlock used for names, etc (reg_lock). This has little value and unnecessarily complicates things.

* lib: Revise port construct in applicationDimitri Staessens2023-09-201-84/+91
| | | | | | | | | | | | | | | | | | The application had a port construct, which is a leftover from the early days implementing RINA specs, which had a "port_id" to access flows. O7s doesn't really have a "port" concept, only flows. The port_wait_assign function was used in the IPCP to wait for the IRMd to assign the flow_id and return so the flow object could be created. This renames things a bit, and also simplifies the locking to us a single lock/condvar for managing flows. This should be further improved to move the flow state into the flow object, maintain a double mapping of to flow objects (id_to_flow and fd_to_flow) and malloc flow objects at flow allocation, instead of keeping the full table in memory at init to further reduce memory footprint.

* ipcpd: Register event handler after scheduler startDimitri Staessens2023-09-201-10/+15
| | | | | | | | | | | The event handler was registered before the scheduler was started. Which could in theory cause addition of fds to an uninitialized scheduler. The event handler is now registered after the scheduler is created as part of dt_start. Likewise it now unregisters as part of dt_stop.

* ipcpd: Simplify including common enrollment codeDimitri Staessens2023-08-305-31/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | This adds the log_xxx_id() macros to print a logline prefixed with a 64-bit identifier in hex format, for instance: [2a92d78c2f52b76a] Hello ouroboros! The ID is assumed to be 8 bytes in big endian format (it uses the HASH_FMT functions and hashes are stored in big endian byte arrays). The implementation uses the compiler-specific '##' operator to allow empty variadics. E.g. func(arg , ## __VA_ARGS__); will eat the comma if __VA_ARGS__ is empty and thus allow func(arg); Signed-off-by: Dimitri Staessens <dimitri@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>
