* Move all sources from the llvm project into contrib/llvm-project.Dimitry Andric2019-12-20215-153750/+0
| | | | | | | | | | | | | This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. Notes: svn path=/head/; revision=355940

Thanks to Eric Fiselier for the patch. Differential Revision: https://reviews.llvm.org/D66836 llvm-svn: 370891 Merge commit b92deded8 from llvm git (by Louis Dionne): [libc++] Move __clamp_to_integral to <cmath>, and harden against min()/max() macros llvm-svn: 370900 Merge commit 0ec6a4882 from llvm git (by Louis Dionne): [libc++] Fix potential OOB in poisson_distribution See details in the original Chromium bug report: https://bugs.chromium.org/p/chromium/issues/detail?id=994957 Together, these fix a security issue in libc++'s implementation of std::poisson_distribution, which can be exploited to read data which is out of bounds. Note there are no programs in the FreeBSD base system that use std::poisson_distribution, so this is only a possible issue for ports and external programs which have been built against libc++. Therefore, I am bumping __FreeBSD_version for the benefit of our port maintainers. Requested by: emaste Security: potential OOB read MFC after: 3 days Notes: svn path=/head/; revision=354460
* Use __FreeBSD_version to determine if gets() has been removed.John Baldwin2019-10-151-1/+3
| | | | | | | | | | | | | | | | | | | | | GCC compilers set __FreeBSD__ statically to a build-time determined targeted version (which in ports always matches the build host's version). This means that when building any version (12 or 13, etc.) of riscv or some other architecture via GCC on a 12.x host, __FreeBSD__ will always be set to 12. As a result, __FreeBSD__ cannot be used to reliably detect the target FreeBSD version being built. Instead, __FreeBSD_version from either <sys/param.h> (in the kernel) or <osreldate.h> (in userland) should be used. This changes the gets() test in libc++ to use __FreeBSD_version from <osreldate.h>.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gets is unsafe and shouldn't be used (for many years now). Leave it in the existing symbol version so anything that previously linked aginst it still runs, but do not allow new software to link against it. (The compatability/legacy implementation must not be static so that the symbol and in particular the compat sym gets@FBSD_1.0 make it into libc.)

* Create new EINTEGRITY error with message "Integrity check failed".Kirk McKusick2019-01-172-13/+42
| | | | | | | | | | | | | | | | | | | | | | An integrity check such as a check-hash or a cross-correlation failed. The integrity error falls between EINVAL that identifies errors in parameters to a system call and EIO that identifies errors with the underlying storage media. EINTEGRITY is typically raised by intermediate kernel layers such as a filesystem or an in-kernel GEOM subsystem when they detect inconsistencies. Uses include allowing the mount(8) command to return a different exit value to automate the running of fsck(8) during a system boot. These changes make no use of the new error, they just add it. Later commits will be made for the use of the new error number and it will be added to additional manual pages as appropriate.
