This is reproducable with v2018.03, v2018.05, v2018.07, v2018.09,
v2018.11 and with current origin/master (358902586727 "Merge branch
'2018-12-06-master-imports'").
For the elder releases I had to apply
d796735c334b "test: overlay: add missing include"
The value of off is -9 in the tests above. This is -FDT_ERR_BADMAGIC.
Adding some debug output sheds more light:
test/overlay/cmd_ut_overlay.c(290) do_ut_overlay: fdt_base_copy
000000007ef33340
test/overlay/cmd_ut_overlay.c(291) do_ut_overlay: uts->priv 000000007ef33340
Running 9 overlay tests
Test: fdt_overlay_add_node_by_path
test/overlay/cmd_ut_overlay.c(127) fdt_overlay_add_node_by_path:
uts->priv 0000000000000000
This is the patch that led to problem:
e93232e15ec9 ("test: overlay: Use cmd_ut_category()")
The uts created in do_ut_overlay() is not the one used in cmd_ut_category().
The easiest fix would be using a static variable for passing the fdt.
The neatest solution would be cmd_ut_category() calling an
initialization function for the category so that we can use a single
instance of uts for the whole test.
As this API is your design I would prefer leaving the resolution to you.
Besides resolving the error I think we should run 'ut overlay' on Travis
CI for all qemu platforms.
Best regards
Heinrich
