Revision 3318a386e4ca68c76e0294363d29bdc46fcad670 authored by Serge Hallyn on 30 October 2008, 16:52:23 UTC, committed by Linus Torvalds on 01 November 2008, 16:49:45 UTC
While Linux doesn't honor setuid on scripts. However, it mistakenly behaves differently for file capabilities. This patch fixes that behavior by making sure that get_file_caps() begins with empty bprm->caps_*. That way when a script is loaded, its bprm->caps_* may be filled when binfmt_misc calls prepare_binprm(), but they will be cleared again when binfmt_elf calls prepare_binprm() next to read the interpreter's file capabilities.
