Revision 11bbd8b416f8abf40900dc5041152892f873d915 authored by Michal Koutný on 01 June 2019, 05:30:16 UTC, committed by Linus Torvalds on 01 June 2019, 22:51:31 UTC
Despite comment of validate_prctl_map claims there are no capability
checks, it is not completely true since commit 4d28df6152aa ("prctl: Allow
local CAP_SYS_ADMIN changing exe_file"). Extract the check out of the
function and make the function perform purely arithmetic checks.
This patch should not change any behavior, it is mere refactoring for
following patch.
