lib: Fix CRC32 hashing

2024-02-19T15:06:34+00:00

I assumed that all hashes were stored in Big Endian, but apparently the CRC32 was still in machine endianness when calculated by the rhash implementation. Fixed and updated hash tests a bit. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Fix missing newlines at end of file

2024-02-19T13:09:38+00:00

Some files had a newline at the end, others didn't. Now they all do. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Revise IRMd internals

2024-02-19T10:49:07+00:00

This is a full revision of the IRMd internal implementation. The registry is now a proper subcomponent managing its own internal lock (a single mutex). Some tests are added for the registry and its data structures. Some macros for tests are added in . Flow allocation is now more symmetric between the client side (alloc) and server size (accept). Each will create a flow in pending state (ALLOC_PENDING/ACCEPT_PENDING) that is potentially fulfilled by an IPCP using respond_alloc and respond_accept primitives. Deallocation is split in flow_dealloc (application side) and ipcp_flow_dealloc (IPCP side) to get the flow in DEALLOC_PENDING and DEALLOCATED state. Cleanup of failed flow allocation is now properly handled instead of relying on the sanitizer thread. The new sanitizer only needs to monitor crashed processes. On shutdown, the IRMd will now detect hanging processes and SIGKILL them and clean up their fuse mountpoints if needed. A lot of other things have been cleaned up and shuffled around a bit.

include: Use common definition between lib and IRMd

2024-01-31T09:27:56+00:00

Some definitions/enums were different between the library and IRMd (flow_state, ipcp_state). This moves them to common ground. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Make list empty on delete

2024-01-31T09:27:56+00:00

The list_del operation now lets nxt and prv point to the element itself, so that list_is_empty(e) is true after list_del(e). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Update licenses to 2024

2024-01-13T09:20:14+00:00

irmd: Fix passing symmetric key on allocation

2023-12-31T15:47:55+00:00

The check if the flow requires a key in irmd flow_alloc was missing when setting the pointers for the piggyback data, so non-encrypted flow allocations failed on irm_msg__pack(). Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Fix wrong fccntl return for FLOWGRCVTIMEO

2023-12-17T12:25:06+00:00

The send timeout was returned instead of the receive timeout. Signed-off-by: Thijs Paelman Signed-off-by: Sander Vrijders

lib: Move public key handling from app to IRMd

2023-12-17T12:23:49+00:00

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.

lib: Fix memleak when creating IPCP

2023-12-17T12:23:49+00:00

The irm_create_ipcp leaked the ipcp_info protobuf message. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
