lib: Fix timeout overflow on 32-bit systems

2023-11-08T08:17:53+00:00

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

lib: Remove pid from flow struct

2023-10-25T09:41:59+00:00

The pid of the N-1 IPCP process was needlessly stored in the flow struct. We only need it to open the right shared memory maps, which is done when the flow is created. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Wrap pthread_cond_timedwait for NULL abstime

2023-10-25T07:53:27+00:00

We often have the pattern where we NULL-check abstime for pthread_cond_timedwait to call pthread_cond_wait if it is. Added a __timedwait function to wrap this. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Make crypt.c independent source file

2023-10-25T07:51:35+00:00

The cryptography functions were in a C source that was directly imported into dev.c, enabling ECDHE+AES256 symmetric key encryption on flows. Now crypt.c is an independent source file with associated crypt.h header, to prepare for security management and configuration in the IRMd.

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.

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

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: Add IDs to enrollment

2023-08-23T11:09:11+00:00

The enrollment messages now have a 64-bit ID to easier track enrollments in the logs in larger scale tests. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

include: Revise printing hashes

2023-08-23T11:09:11+00:00

The code was a bit convoluted to print hashes as hex strings. Renamed to HASH_FMT32 and HASH_VAL32 to make clear we are printing the first 32 bits only, and added options to print 64 up to 512 bits as well. This doesn't depend on endianness anymore. Adds a small test for the hash (printing) functions. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
