get psci states without check in fuinc ‘’psci_do_state_coordination‘’
Closed, ResolvedPublic


In function 'psci_do_state_coordination', the req_states returns from ‘psci_get_req_local_pwr_states‘,and will be 'NULL' when pwrlvl is not valid. 'plat_get_target_pwr_state' uses req_states without any check will lead to unexpected result.

thanks a lot.

As you mentioned, req_states will be NULL only if pwrlvl is not valid. However, in my opinion, many checks have been done earlier to the invocation of the function to make sure pwrlvl is valid. See lines 246 and 428 in lib/psci/psci_common.c file. Can you tell if you have noticed any issue in your platform with PSCI library?

Ok, thanks a lot.
