* ssp: appease -Wgnu-statement-expression-from-macro-expansionKyle Evans8 days7-13/+13
| | | | | | | | | | | | | | | It's a stupid warning, but some ports enable it by default and were already defining _FORTIFY_SOURCE, thus exposing the new macros immediately. This at least fixes the libfido2 build, perhaps others as well. While we're here, fix a fresh build of stand w/ FORTIFY_SOURCE enabled by not pulling in the ssp headers if _STANDALONE is defined. We do not have runtime support in libsa as of the time of writing. Reported by: netchild Sponsored by: Stormshield Sponsored by: Klara, Inc.

| | | | | We haven't exposed gets(3) in a long time, rip out __gets_chk before it's too late and something builds a gets(3) user with it enabled.
* Add a build knob for _FORTIFY_SOURCEKyle Evans10 days4-0/+13
| | | | | | | | | | | | | | | | | In the future, we will Default to _FORTIFY_SOURCE=2 if SSP is enabled, otherwise default to _FORTIFY_SOURCE=0. For now we default it to 0 unconditionally to ease bisect across older versions without the new symbols, and we'll put out a call for testing. include/*.h include their ssp/*.h equivalents as needed based on the knob. Programs and users are allowed to override FORTIFY_SOURCE in their Makefiles or src.conf/make.conf to force it off.

* Prepare the system for _FORTIFY_SOURCEKyle Evans10 days1-2/+6
| | | | | | | | | | | | | | | Notably: - libc needs to #undef some of the macros from ssp/* for underlying implementations - ssp/* wants a __RENAME() macro (snatched more or less from NetBSD) There's some extra hinkiness included for read(), since libc spells it as "_read" while the rest of the world spells it "read."

| | | | | | | | | | | | | | | | There is a conflict between bsm/audit.h and security/audit/audit.h due to the way that staging is being set up using .PATH to point to the full directory and the leaf files being specified in the list. Due to this, the bsm/audit.h was getting staged as both bsm/audit.h and security/audit/audit.h since the sys/bsm directory is listed first in the .PATH list. Use sys/security in the .PATH instead of sys/security/audit and specify the audit header files as audit/<name>.h. This ensures that we get the correct audit.h stanged for security/audit/audit.h.

* pf: convert state retrieval to netlinkAlexander V. Chernikov2023-10-101-1/+2
| | | | | | | | | | | | | | | | | | | | Use netlink to export pf's state table. The primary motivation is to improve how we deal with very large state stables. With the previous implementation we had to build the entire list (both in the kernel and in userspace) before we could start processing. With netlink we start to get data in userspace while the kernel is still generating more. This reduces peak memory consumption (which can get to the GB range once we hit millions of states). Netlink also makes future extension easier, in that we can easily add fields to the state export without breaking userspace. In that regard it's similar to an nvlist-based approach, except that it also deals with transport to userspace and that it performs significantly better than nvlists. Testing has failed to measure a performance difference between the previous struct-copy based ioctl and the netlink approach. Differential Revision: https://reviews.freebsd.org/D38888

* pkgbase: Move headers and libs out of runtime and utilitiesDoug Rabson2023-09-122-1/+3
| | | | | | | | | | | | | | | | | | | | Headers from src/include were in the runtime-dev package but subdirectories of src/include ended up in utilities-dev by default. Neither package is a good choice - the headers in src/include are not useful without the libraries contained in clibs-dev. This moves the standard C headers to clibs-dev (C++ headers are already in this package). While working on this, I found that various clang libraries and headers were also bundled into utilities-dev by default so these are also moved to clang-dev. I also added a FreeBSD-build-essential meta package to make it simple to install all the toolchain parts.

The goal is to allow a daemon to run as an unprivileged process while still being able a set of privileged operations needed. We add APIs to libveriexec so that userland processes can check labels and an exec_script API that allows a suitably labeled process to run something like a python interpreter directly if necessary; overcomming the 'indirect' flag applied to the interpreter.

* arm64 lib32: prepare arm64 headers to redirect to armMike Karels2023-07-252-4/+69
| | | | | | | | | | | | | | | | | | | | | | | In order to compile lib32 libraries and other 32-bit code on arm64, <machine/foo.h> needs to be redirected to an arm header rather than arm64 when building with -m32. Ifdef the arm64 headers that are installed in /usr/include/machine and used by user-level software (including references from /usr/include/*.h) so that if __arm__ is defined when including the arm64 version, <arm/foo.h> is included rather than using the rest of the file's contents. Some arm headers had no arm64 equivalent; headers were added just to do the redirection. These files use #error if __arm__ is not defined to guard against confusion. Also add an include/arm Makefile, and modify Makefiles as needed to install everything, including the arm files in /usr/include/arm. fenv.h comes from lib/msun/arm/fenv.h.

Thus, guard the definition here so that rtld_paths.h's definition continues to take precedence. Note that, although all in-tree uses of _PATH_ELF_HINTS have included rtld_paths.h already, pax-utils wants _PATH_ELF_HINTS from elf-hints.h and so we cannot just drop the define. In-tree uses must just continue to make sure that they include rtld_paths.h to get the right value for libcompat builds as is already required.
