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.
