6.2.0

30 April 2023

Clixon 6.2.0 brings no new major feature changes, but completes YANG
schema mount and other features required by the clixon controller
project, along with minor improvements and bugfixes.

API changes on existing protocol/config features

Users may have to change how they access the system

  • New clixon-config@2023-03-01.yang revision
    • Added options: CLICON_RESTCONF_NOALPN_DEFAULT
    • Extended datastore-format with CLI and text
  • New clixon-lib@2023-03-01.yang revision
    • Added creator meta-object

C/CLI-API changes on existing features

Developers may need to change their code

  • C-API
    • clixon_xml2file and clixon_xml2cbuf added prefix argument
      • Example application is to add "+"/"-" for diffs
      • Example change:
        • clixon_xml2file(f,x,p,f,s,a) -> clixon_xml2file(f,x,p,NULL,f,s,a)
        • clixon_xml2cbuf(c,x,l,p,d,s) -> clixon_xml2cbuf(c,x,l,p,NULL,d,s)
    • xmldb_validate is removed. Yang checks should be enough, remnant of time before YANG checks.
    • xml_diff: removed 1st yspec parameter
    • xml2xpath(): Added int apostrophe as 4th parameter, default 0
      • This is for being able to choose single or double quote as xpath literal quotes
    • clicon_msg_rcv: Added intr parameter for interrupting on ^C (default 0)
    • Renamed include file: clixon_backend_handle.hto clixon_backend_client.h
    • candidate_commit(): validate_level (added in 6.1) marked obsolete

Minor features

  • Adjusted to Openssl 3.0
  • Unified netconf input function
    • Three different implementations were used in external, internal and controller code
      • Internal netconf still not moved to unified
    • The new clixon_netconf_input API unifies all three uses
    • Code still experimental controlled by NETCONF_INPUT_UNIFIED_INTERNAL
  • RFC 8528 YANG schema mount
    • Made cli/autocli mount-point-aware
  • Internal NETCONF (client <-> backend)
    • Ensure message-id increments
    • Separated rpc from notification socket in same session
  • Restconf: Added fallback mechanism for non-ALPN HTTPS
    • Set CLICON_RESTCONF_NOALPN_DEFAULT to http/2 or http/1.1
    • For http/1 or http/2 only, that will be the default if no ALPN is set.
  • Fixed: Add support decimal64 for SNMP

Corrected Bugs

  • Fixed RESTCONF race conditions on SSL_shutdown sslerr ZERO_RETURN appears occasionally and exits.
  • Fixed: RESTCONF: some client cert failure leads to restconf exit. Instead close and continue
