Linus Torvalds ce69fb3b39 Refactor kallsyms_show_value() users for correct cred 
Several users of kallsyms_show_value() were performing checks not
 during "open". Refactor everything needed to gain proper checks against
 file->f_cred for modules, kprobes, and bpf.

Merge tag 'kallsyms_show_value-v5.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull kallsyms fix from Kees Cook:
 "Refactor kallsyms_show_value() users for correct cred.

  I'm not delighted by the timing of getting these changes to you, but
  it does fix a handful of kernel address exposures, and no one has
  screamed yet at the patches.

  Several users of kallsyms_show_value() were performing checks not
  during "open". Refactor everything needed to gain proper checks
  against file->f_cred for modules, kprobes, and bpf"
