Inspired by Marco Veeneman. Change signature of get_value function to return s16_t, where values <0 indicate an error. This is mapped to SNMP_ERR_GENERROR.
- The abstraction from crypto framework was not well suitable to MBEDTLS, so I decided to move everything into an own file.
- I removed several #defines and created function prototypes instead - this is more type-safe, and users don't need to reinvent the function signatures.
- Header files were splitted into a public and a private part.
- Only SNMPv3 authentication was tested, privacy not yet.
- SNMPv2c support
- Greatly reduced RAM usage, no memory pools any more
- API cleanup
- MIB2 is separated from SNMP stack
- Support for multiple MIBs (snmp_set_mibs call) - e.g. for private MIB
- Improved MIB2 implementation (tcpConnTable etc.)
- Redesigned simple and generic API for MIB implementation
- Comfortable node types for scalar arrays and tables
- Counter64, bit and truthvalue datatype support
- Callbacks for SNMP writes
- Runs on two APIs: RAW and netconn
- Async API is gone - the stack now supports netconn API instead,
so blocking operations can be done in MIB calls.
SNMP runs in a worker thread when netconn API is used.
- Simplified thread sync support for MIBs - useful when MIBs
need to access variables shared with other threads without locking
(used in MIB2 to access lwIP stats from lwIP thread)
Currently in work:
- Traps rewrite
- MIB compiler
