Previously open(2) was allowed in capability mode, with a comment that suggested this was likely the case to facilitate debugging. The system call would still fail later on, but it's better to disallow the syscall altogether. We now have the kern.trap_enotcap sysctl or PROC_TRAPCAP_CTL proccontrol to aid in debugging. In any case libc has translated open() to the openat syscall since r277032. Reviewed by: kib, rwatson Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D10850

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
