* Tackle the endian.h mess. Make it so that:guenther2014-07-121-4/+6
| | | | | | | | | | | | | | | | | | * you can #include <sys/endian.h> instead of <machine/endian.h>, and ditto <endian.h> (fixes code that pulls in <sys/endian.h> first) * those will always export the symbols that POSIX specified for <endian.h>, including the new {be,le}{16,32,64}toh() set. c.f. http://austingroupbugs.net/view.php?id=162 if __BSD_VISIBLE then you also get the symbols that our <machine/endian.h> currently exports (ntohs, NTOHS, dlg's bemtoh*, etc) * when doing POSIX compiles (not __BSD_VISIBLE), then <netinet/in.h> and <arpa/inet.h> will *stop* exporting the extra symbols like BYTE_ORDER and betoh* ok deraadt@
* CPU_BUSY_CYCLE(): A new MI statement for busy loop power reductionuebayasi2014-07-111-1/+3
| | | | | | | | | | The new CPU_BUSY_CYCLE() may be put in a busy loop body so that CPU can reduce power consumption, as Linux's cpu_relax() and FreeBSD's cpu_spinwait(). To start minimally, use PAUSE on i386/amd64 and empty on others. The name is chosen following the existing cpu_idle_*() functions. Naming and API may be polished later. OK kettenis@

* Move the increment of uvmexp.softs back to the caller of mi_ast():guenther2014-05-111-1/+2
| | | | | | | it needs to be done atomicly on some MP archs and we don't have atomic_add_int() everywhere yet. Also, mi_ast() was meant to be inline. noted by miod@

* Have each thread keeps its own (counted!) reference to the process's ucredsguenther2014-04-181-1/+4
| | | | | | | | | to avoid possible use-after-free references when swapping ids in threaded processes. "Do I have the right creds?" checks are always made with the threads creds. Inspired by FreeBSD and NetBSD "right time" deraadt@

| | | | | | | | | struct ucred; struct process then directly links to the ucred Based on a discussion at c2k10 or so before noting that FreeBSD and NetBSD did this too. ok matthew@

* Move p_emul and p_sigcode from proc to process.guenther2014-03-262-7/+7
| | | | | | | | | Tweak the handling of ktrace EMUL when changing ktracing: only generate one per process (not one per thread) and pass the correct proc pointer down to the VFS layer. Permit generating of NAMI and CSW records inside ktrace(2) itself. ok deraadt@ millert@

| | | | | | <machine/pmap.h> where it belongs, and compensate in <uvm/uvm_extern.h> by including <uvm/uvm_pmap.h> before <uvm/uvm_page.h>. Tested on all MACHINE_ARCH but amd64 and i386 (and hppa64).

| | | | | | | | make it a list of processes, and change P_NOZOMBIE and P_STOPPED from thread flags to process flags. Add allprocess list for the code that just wants to see processes. ok tedu@

* cleanup and consolidate the spinlock_lock (what a name!) code.tedu2013-06-011-4/+8
| | | | | | | | | | it's now atomic_lock to better reflect its usage, and librthread now features a new spinlock that's really a ticket lock. thrlseep can handle both types of lock via a flag in the clock arg. (temp back compat hack) remove some old stuff that's accumulated along the way and no longer used. some feedback from dlg, who is concerned with all things ticket lock. (you need to boot a new kernel before installing librthread)
