ipcpd: Broadcast destruction of DHT requests

2023-09-20T16:53:25+00:00

When a request is cancelled/destroyed, all blocking threads should exit. Noticed some hangs on the DHT, this seems to fix/reduce it. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Revise port construct in application

2023-09-20T16:51:19+00:00

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: Fix dereference of unknown pointer type

2023-09-20T16:51:19+00:00

The event handler was dereferencing the pointer to a connection, but the pointer type is not known yet. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Register event handler after scheduler start

2023-09-20T16:51:19+00:00

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.

lib: Revise application init and fini

2023-09-20T16:51:19+00:00

The init will now print more useful errors if a process fails to initialize. Also rearranged these procedures a little bit. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Rename portevent to flowevent

2023-09-20T16:51:19+00:00

Doesn't make any sense to call it a port event... Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Print ascii Ouroboros logo at startup

2023-09-20T16:51:19+00:00

The IRMd will now print a stylized logo at startup: ▄▄█████▄▄▄ ▄█▀▀ ▀▀███▄ █ ██ ▄▄▄ ▄███▄ ▄ ▄ ▄ ▄▄ ▄▄ █ ▄▄ ▄▄ ▄ ▄▄ ▄▄ ▄▄ ██ █ █ █████ █ █ █▀ ▀ █ █ █▀ █ █ █ █▀ ▀ █ █ ▀▄ ▀ ██ ▀▄▄▄▀ ▀█▀ █ █ █ █ █ █▄ █ █ █ █ █ █ ▄ ▀▄ █▄ █ ▀▀▀ ▀ ▀ ▀▀ ▀ ▀▀ ▀▀ ▀ ▀▀ ▀▀ ▀█▄▄▄▄▄▄▄▄▀ ▀▀▀▀▀▀ All credits to Zen for providing the ASCII art!

ipcpd: Revise logging

2023-08-30T15:12:41+00:00

This revises the logging in the IPCPs to be a more consistent and reduce duplicate messages in nested functions. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Move protobuf definitions to pb/ directory

2023-08-30T15:11:41+00:00

This moves the protobuf definition in the library to a pb/ directory. Also renames the protobuf files and does a quick review of the #define guards in the include library to specify _LIB_ for internal/non-public library headers. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

ipcpd: Move alloc race mitigation to common source

2023-08-30T08:33:20+00:00

All flow allocator code was duplicating the mitigation for a race where the IRMd response for the flow allocation with a new flow fd was arriving before the response to the flow_req_arr. This is now moved to the ipcp common source. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
