[PATCH] arm64: module: PLT allowed even !RANDOM_BASE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Module PLT feature can be enabled even when RANDOM_BASE is disabled.
Break BLT entry counts of relocation types will make module plt entry
allocation fail and finally exec format error for even correct and plt
allocation available modules.
