However, it doesn't add these to # __clear_user(), which is used in the ptrace regset code. # # As there's only one direct user of __clear_user() (the regset code), # and the time taken to set the AMR for KUAP purposes is going to # dominate the cost of a quick access_ok(), there's not much point # having a separate path. # # Rename __clear_user() to __arch_clear_user(), and make __clear_user() # just call clear_user(). # # Reported-by: syzbot+f25ecf4b2982d8c7a640@syzkaller-ppc64.appspotmail.com # Reported-by: Daniel Axtens <dja@axtens.net> # Suggested-by: Michael Ellerman <mpe@ellerman.id.au>
