clixon/test/test_nacm_module_write.sh
Olof hagsand e7b60619da * Pushed tag to 4.0.1.PRE 
* Restconf RFC 8040 increased feature compliance
  * Cache-Control: no-cache added in HTTP responses (RFC Section 5.5)
  * Restconf monitoring capabilities (RFC Section 9.1)
* Added support for Yang extensions
  * New plugin callback: ca_extension
  * Main backend example includes example code on how to implement a Yang extension in a plugin.
* JSON changes
  * Non-pretty-print output removed all extra spaces.
    * Example: `{"nacm-example:x": 42}` --> {"nacm-example:x":42}`
  * Empty JSON container changed from `null` to `{}`.
    * Empty list and leafs remain as `null`
* Removed unnecessary configure dependencies
  * libnsl, libcrypt, libm, if_vlan,...
* pseudo-plugin added, to enable callbacks also for main programs. Useful for extensions
* Yang Unique statements with multiple schema identifiers did not work on some platforms due to memory error.

# Authentication and authorization and IETF NACM
# NACM module rules
# A module rule has the "module-name" leaf set but no nodes from the
# "rule-type" choice set.
# @see test_nacm.sh is slightly modified - this follows the RFC more closely
# See RFC 8341 A.1 and A.2
# Note: use clixon-example instead of ietf-netconf-monitoring since the latter is
# A) Three tracks in the code for leaf/leaf-list, container/lists, and root
# B) Three operations: create, update, delete (write)
# C) Two access operations: permit, deny (also default deny/permit)
# This gives 18 testcases
# Set group access:
# - Admin: permit: create, update, delete
# - Limit: permit: create, delete; deny: update
# - Guest: permit: update; deny: create delete
# ops\track:| root | leaf | list
#-----------+--------+--------+----------

# delete | p/d | p/d | p/d
