lib: Revise app flow allocation

2024-02-23T15:41:37Z

This revises the application flow allocator to use the flow_info struct/message between the components. Revises the messaging to move the use protocol buffers to its own source (serdes-irm). Adds a timeout to the IRMd flow allocator to make sure flow allocations don't hang forever (this was previously taken care of by the sanitize thread).

lib: Wrap pthread_cond_timedwait for NULL abstime

2023-10-25T07:53:27Z

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

2023-10-25T07:51:35Z

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.

include: Revise printing hashes

2023-08-23T11:09:11Z

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 signed/unsigned mismatches on raspbian

2023-08-23T11:09:10Z

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

lib: Rename timerwheel_ack timerwheel_delayed_ack

2022-04-13T06:54:15Z

This makes it clear that we are scheduling a potential delayed acknowledgment instead of acknowledging a packet scheduled for retransmission. Also some small cosmetic fixes. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix delayed ACK under high load

2022-04-03T16:01:01Z

The delayed ACK was wrongly measuring the delay against the receiver activity instead of the sender activity. Also fixed receiver activity not being updated for non-data packets (and duplicates and other dropped traffic). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
