* Add a ${CP} alias for copying files in the build.Will Andrews2015-01-161-1/+1
| | | | | | | | | | | | | | | | | Some users build FreeBSD as non-root in Perforce workspaces. By default, Perforce sets files read-only unless they're explicitly being edited. As a result, the -f argument must be used to cp in order to override the read-only flag when copying source files to object directories. Bare use of 'cp' should be avoided in the future. Update all current users of 'cp' in the src tree. Reviewed by: emaste MFC after: 1 week Sponsored by: Spectra Logic Notes: svn path=/head/; revision=277273

* sh: Make sure output suitable as shell input is also printable.Jilles Tjoelker2014-12-143-22/+76
| | | | | | | | | | | | | | Commands like 'export -p', 'set' and 'trap', and tracing enabled via 'set -x' generate output suitable as shell input by adding quotes as necessary. If there are control characters other than newline or invalid UTF-8 sequences, use $'...' and \OOO to display them safely. The resulting output is not parsable by a strict POSIX.1-2008 shell but sh from FreeBSD 9.0 and newer and many other shells can parse it. Notes: svn path=/head/; revision=275766
* Add facility to stop all userspace processes. The supposed use of theKonstantin Belousov2014-12-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | feature is to quisce the system before suspend. Stop is implemented by reusing the thread_single(9) with the special mode SINGLE_ALLPROC. SINGLE_ALLPROC differs from the existing single-threading modes by allowing (requiring) caller to operate on other process. Interruptible sleeps for !TDF_SBDRY threads are suspended like SIGSTOP does it, instead of aborting the sleep, like SINGLE_NO_EXIT, to avoid spurious EINTRs on resume. Provide debugging sysctl debug.stop_all_proc, which causes total stop and suspends syncer, while waiting for variable reset for resume. It is used for debugging; should be removed after the real use of the interface is added.

* sh: Make getopts memory-safe if with changing arguments.Jilles Tjoelker2014-10-265-6/+39
| | | | | | | | | | | | | | | POSIX does not permit to continuing a getopts loop with different arguments. For parsing the positional parameters, we handle this case by resetting the getopts state when the positional parameters are changed in any way (and the getopts state is local to a function). However, in the syntax getopts <optstring> <var> <arg...>, changes could lead to invalid memory access. In the syntax getopts <optstring> <var> <arg...>, store a copy of the arguments and continue to use them until getopts is reset. Notes: svn path=/head/; revision=273700

* Revert r267233 for now. PIE support needs to be reworked.Bryan Drewery2014-08-191-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | 1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other build-only utility libraries. 2. Another 40% is fixed by generating _pic.a variants of various libraries. 3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR) where it never would work anyhow, such as csu or loader. This suggests there may be better ways of adding support to the tree. Many of these cases can be fixed such that -fPIE will work but there is really no reason to have it in those cases. 4. Some of the uses are working around hacks done to some Makefiles that are really building libraries but have been using bsd.prog.mk because the code is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have been needed. We likely do want to enable PIE by default (opt-out) for non-tree consumers (such as ports). For in-tree though we probably want to only enable PIE (opt-in) for common attack targets such as remote service daemons and setuid utilities. This is also a great performance compromise since ASLR is expected to reduce performance. As such it does not make sense to enable it in all utilities such as ls(1) that have little benefit to having it enabled. Reported by: kib Notes: svn path=/head/; revision=270168
