libcsp 1.6, 16-04-2020
----------------------
- Updated documentation.
- Updated Python bindings, removed Python2 support.
- Removed timeout for send (internally only) and interface tx functions - the timeout was only used on I2C interface.
- Updated example code to a single csp_server_client.c implementation.
- Renamed (scoped) clock_set_time()/clock_get_time() to csp_clock_set_time()/csp_clock_get_time()
- Changed csp_sys_reboot()/csp_sys_shutdown() to use callbacks, default POSIX impl. in csp/arch/posix/csp_system.h.
- Added support for timestamps in logs by setting CSP_DEBUG_TIMESTAMP (uses csp_clock_get_time()).
- Renamed mac to via (structs, functions, examples and documentation)
- RDP: Ensure connection is kept in CLOSE_WAIT for period of time. In some cases, the connection would switch to CLOSED immediately.
- RDP: Fixed connection leak, if a RST segment was received on a closed connecton.
- RDP: Ensure connection is closed from both userspace and protocol, before closing completely (preventing undetermined behaviour).
- RDP: Added support for fast close of a connection (skipping the CLOSE_WAIT period), but only if both ends agree on close.
- RDP: Fixed issue "Possible bug in RDP TX timeout" (#109), see issue on github for further details.
- Added Travis-CI support on Github, build: Linux, Mac and Windows.
- Changed #ifdef/ifndef to single #if in order to support forced disabling and alignment with log macro's.
- Updated thread API, documentation, aligned implementation
- Refactored all CSP interfaces.
- Accept csp_route_t, instead of csp_iface_t.
- No static members -> multiple interfaces of all types.
- Added csp_iface_t.interface_data for interface data.
- Added csp_iface_t.driver_data for driver data (unknown to interface level).
- Check for buffer overrun
- Set MTU if not already set, and it make sense on the respective interface.
- Driver Tx function is now a callback, must be set by the application (in the interface data).
- csp_packet_t (and other structs) are no longer packed (increases performance), padding is increased from 8->10 bytes for alignment.
- Refactored rtable CIDR/static implementation:
- Use same format for storing table (text).
- Added csp_route_t to hold route entry, e.g. interface and via.
- Replaced csp_rtable_find_iface()/csp_rtable_find_mac() with csp_rtable_find_route()
- Added csp_get_memfree()/csp_get_buf_free()/csp_get_uptime(), which returns an error code.
- Improved logging, check level before doing the actual call. Added support for external log macros.
- Removed unused defines/functions: csp_conn_lock, csp_conn_unlock, CSP_PROMISC
- Replaced CSP_MAX_DELAY and CSP_INFINITY with CSP_MAX_TIMEOUT (same value).
- Added csp_calloc(), csp/arch/csp_malloc.h
- Added csp_buffer_data_size(), csp/csp_buffer.h
- Updated header documentation (doxygen).
- Restructured header includes.
- api: Added const for read-only pointers.
- api: Changed a number of uint8_t pointers to void to avoid cast.
libcsp 1.5-internal, 21-08-2018
-------------------------------
