This patch allows the application to modify the CID, PID and VID in the composition data. Version 2: Do not allow to change CRPL in the composition data. Additionaly verify the device key when updating comp data and remove unused function in the 3rd patch. Version 1: According the Mesh Profile (2.3.4 Elements) the modification of fields other than "Elements" is not prohibited. Also in my opinion (as you can see in the 1st patch), there is no need to use pointer to the node_composition struct. The static is more clear and less problematic. Jakub Witowski (4): mesh: use static node_comp instead of the pointer mesh: add cid/pid/vid setter mesh: remove unused node_set_device_key() mesh: allow to reattach with new composition data mesh/mesh-config-json.c | 40 ++++++++++++---- mesh/mesh-config.h | 2 + mesh/node.c | 100 +++++++++++++++++++++++++--------------- mesh/node.h | 1 - 4 files changed, 96 insertions(+), 47 deletions(-) -- 2.20.1
