running set*id processes. To do this, the bprm_secureexec LSM hook is collapsed into the bprm_set_creds hook so the secureexec-ness of an exec can be determined early enough to make decisions about rlimits and the resulting memory layouts. Other logic acting on the secureexec-ness of an exec is similarly consolidated. Capabilities needed some special handling, but the refactoring removed other special handling, so that was a wash. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Kees Cook <kees@outflux.net> iQIcBAABCgAGBQJZrwRKAAoJEIly9N/cbcAmhboP/iwLbYfWngIJdu3pYKrW+CEg uUVY6RNnsumJ5yEhD/yQKXSPmZ8PkC8vexPYvf8TcPOlMRQuhVvdiR0FfSUvkMWy pB8ZVCyAV1uSnW4BH61FCxHInrahy8jlvQwnAujvw+FNxhcQjyEGKupOLIMGLioQ 8G5Ihf+hOjiXRhKbXueQi89n8i4jEI5YTH1RnC+Gsy8jG11EC9BhPddKSMaUKZA3 HYYqUyV0daYpGuxTOxaRdDO5wb6rlS+B46hqtOsSsIBOQkCjnLCRcdeMCqvXjQmv kyZj03cPlUjEHqh3d3nB6utvVWReGf/p986//kQjT1OZPhATbySAu7wUHoLik3dU zuexudNTBROf6YXahMxSJp348GS++xoBFARa78402E++U7C4/eoclbLCWAylBwVA H+QAHFYRC2WFoskejSYBRPz6HLr1SIaSYMsKbkHqP07zi6p3ic2Uq3XvOP2zL/5p l/mXa1Fs2vcDOWPER8a8b9mVkJDvuXj6J11lG+q80UWAWC3sd9GkSwOen80ps3Xo /7dd+h2BAJSSVxZQFxd5YCx99mT0ntQZ797PhjxOY6SX/xUdOCAp9x1zDU5OUovP q2ty3UTd7tq8h1RnHOnrn9cKmMmI7kpBvEfPGM507cEVjyfsMu2jJtUxN9dXOAkB aebEsg3C8M6z5OdGVpWH =Yva4 -----END PGP SIGNATURE----- Merge tag 'secureexec-v4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull secureexec update from Kees Cook: "This series has the ultimate goal of providing a sane stack rlimit when running set*id processes.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
