Hello Takahiro,
Jose's ESRT implementation calls efi_firmware_fit_get_image_info()
multiple times. This results in a segmentation fault in the depths of
dfu_free_entities() involving device_chld_remove().
I used
env set dfu_alt_info "sf 0:0=u-boot-bin raw 0x100000 0x50000;u-boot-env
raw 0x150000 0x200000"
for testing on sandbox_defconfig.
If I comment out the dfu_free_entities() calls the segmentation fault is
avoided.
Could you, please, check with Lukasz when and if you should call
dfu_free_entities() in efi_get_dfu_info().
Best regards
Heinrich

I'm not sure yet, but dfu_init_env_entities() and dfu_free_entities()
are always paired in get_image_info() as in other use cases like
dfu and thordown commands.
