These architectures should use probe_read_{user,kernel}_str # helpers. # # For backward compatibility, the problematic functions are still # available on architectures where the user and kernel address spaces # are not overlapping. This is defined # CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE. # # At the moment, these backward compatible functions are enabled only on # x86_64, arm, and arm64. Let's do it also on powerpc that has the non # overlapping address space as well. # # Fixes: 0ebeea8ca8a4 ("bpf: Restrict bpf_probe_read{, str}() only to archs where they work") # Signed-off-by: Petr Mladek #
