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

lib: Fix lengths of shared memory objects

2023-08-23T11:09:10+00:00

Seems like all shared memory objects were truncated to a size that came up a byte short. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix lockfile length

2023-08-23T11:09:10+00:00

Off-by-one error in lockfile file length. Refactor to reduce code duplication. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix signed/unsigned mismatches on raspbian

2023-08-23T11:09:10+00:00

Compilation on raspberry pi revealed some previously undetected signed/unsigned comparisons in the library. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Link libcrypt and fix cmake compatibility

2023-08-23T11:09:10+00:00

Compatibility with versions of CMake older than 3.5 is deprecated from CMake 3.27 onwards, and will be removed from a future version. Calls to cmake_minimum_required() or cmake_policy() that set the policy version to an older value now issue a deprecation diagnostic. Fixed by indicating a max tested value for cmake_minimum_required(). Changed linking with OpenSSL to link with libcrypto only, we don't require libssl.
