It was using the value of the cpu's %cr2 register but thats not valid: CR2 Contains a value called Page Fault Linear Address (PFLA). When a page fault occurs, the address the program attempted to access is stored in the CR2 register. And this is thus NOT the illegal instruction address! kern/kern_sig.c by christos: PR kern/45327: Jared McNeill: ptrace: siginfo doesn't work with traced processes When saving the signal in p->p_xstat, clear it from the pending mask, but don't remove it from the siginfo queue, so that next time the debugger delivers it, the original information is found. When posting a signal from the debugger l->l_sigpendset is not set, so we use the process pending signal and add it back to the process pending set. Split sigget into sigget() and siggetinfo(). When a signal comes from the debugger (l->l_sigpendset == NULL), using siggetinfo() try to fetch the siginfo information from l->l_sigpend and then from p->p_sigpend if it was not found. This allows us to pass siginfo information for traps from the debugger. don't delete signal from the debugger. kern/kern_sleepq.c by christos: PR kern/40594: Antti Kantee: Don't call issignal() here to determine what errno to set for the interrupted syscall, because issignal() will consume the signal and it will not be delivered to the process afterwards. Instead call sigispending() (which now returns the first pending signal) and does not consume the signal. We need to process SA_STOP signals immediately, and not deliver them to the process. Instead of re-structuring the code to do that, call issignal() like before in that case. (tail -F /file^Zfg should not get interrupted). kern/kern_subr.c by jmcneill, christos: PR kern/45312: ptrace: PT_SETREGS can't alter system calls Add a new PT_SYSCALLEMU request that cancels the current syscall, for use with PT_SYSCALL.

Fix sigactsunshare() to do what the manpage and the commit tells it to do! I.e. unshare a process its sigacts by creating a new one BUT maintaining all signal state. The old code would CLEAR all the signal state. It used to work only due to the fact that sigactunshare() is only used in execsigs() and the fact that SIG_DFL was NULL.

Remove pfind() and pgfind(), fix locking in various broken uses of these. Rename real routines to proc_find() and pgrp_find(), remove PFIND_* flags and have consistent behaviour. Provide proc_find_raw() for special cases. Fix memory leak in sysctl_proc_corename(). COMPAT_LINUX: rework ptrace() locking, minimise differences between different versions per-arch. Note: while this change adds some formal cosmetics for COMPAT_DARWIN and COMPAT_IRIX - locking there is utterly broken (for ages). Fixes PR/43176.

More changes to improve kern_descrip.c. - Avoid atomics in more places. - Remove the per-descriptor mutex, and just use filedesc_t::fd_lock. It was only being used to synchronize close, and in any case we needed to take fd_lock to free the descriptor slot. - Optimize certain paths for the <NDFDFILE case. - Sprinkle more comments and assertions. - Cache more stuff in filedesc_t. - Fix numerous minor bugs spotted along the way. - Restructure how the open files array is maintained, for clarity and so that we can eliminate the membar_consumer() call in fd_getfile(). This is mostly syntactic sugar; the main functional change is that fd_nfiles now lives alongside the open file array. Some measurements with libmicro: - simple file syscalls are like close() are between 1 to 10% faster. - some nice improvements, e.g. poll(1000) which is ~50% faster.

Change how we make SA threads not generate upcalls. Instead of clearing LW_SA, use a private flag, LP_SA_NOBLOCK, that we set when we want to not generate upcalls. This means we do NOT need to lock (l) (ourselves) to set it. Adjust tests that look at LW_SA. Now, we are an upcall-generating lwp if ((l->l_flag & LW_SA) && (~l->l_pflag & LP_SA_NOBLOCK)). Introduce code pattern to set & remember this: f = ~l->l_pflag & LP_SA_NOBLOCK; l->l_pflag |= LP_SA_NOBLOCK; ... /* f is now LP_SA_NOBLOCK if it wasn't set in l_pflag before */ l->l_pflag ^= f; I updated a lot of the trap handlers to do trap handling iff LP_SA_NOBLOCK is not set. I tried to figure out if the trap handler could be triggered for user-based faults as opposed to kernel faults to user addresses, and only look at LP_SA_NOBLOCK for the latter. Above is a result of discussions with rmind at to reduce lock twiddling. Also, per same discussions, add locking to sys_sa_preempt(). p_lock is the lock we want. Also, per same discussions, remove use of LSSUSPENDED as a thread state. We needed to use it when we were emulating the 4.X and previous behavior of hiding cached threads. For the moment, we now have them instead remain visible to all and have them sleeping on the "lwpcache" wait channel. sa_newcachelwp(): sa_putcachelwp() wants savp_mutex held, not p_lock. Tweak some comments.

Add getucontext32_sa() and getucontext_sa(), and use them. They
are sa-specific versions of getucontext{,32}(). The main difference
is that they do NOT require the p_lock be held. We report an empty
signal mask, both to avoid needing p_lock and because the process
signal mask is almost always 0 for SA.

Check in merge of signal handling changes. This is a fairly-direct port of what existed before SA was removed. Expicitly add a sigset_t named sa_sigmask to sadata, and use it to note what signals are masked for an SA thread. Clear it out when going SA. Tweak how we clear LW_SA when we're allocating space for delivering a signal - the whole point is we don't want to generate a BLOCKED upcall, so we have to clear it BEFORE we allocate, not after (like the old code seems to have done). While here, tweak indentation in savar.h to improve readability.

Per discussion with ad at n dot o, revert signal mask handling changes. The l_sigstk changes are most likely totally un-needed as SA will never use a signal stack - we send an upcall (or will as other diffs are brought in). The l_sigmask changes were too controvertial. In all honesty, I think it's probably best to revert them. The main reason they were there is the fact that in an SA process, we don't mask signals per kernel thread, we mask them per user thread. In the kernel, we want them all to get turned into upcalls. Thus the normal state of l_sigmask in an SA process is for it to always be empty. While we are in the process of delivering a signal, we want to temporarily mask a signal (so we don't recursively exhaust our upcall stacks). However signal delivery is rare (important, but rare), and delivering back-to-back signals is even rarer. So rather than cause every user of a signal mask to be prepared for this very rare case, we will just add a second check later in the signal delivery code. Said change is not in this diff. This also un-compensates all of our compatability code for dealing with SA. SA is a NetBSD-specific thing, so there's no need for Irix, Linux, Solaris, SVR4 and so on to cope with it. As previously, everything other than kern_sa.c compiles in i386 GENERIC as of this checkin. I will switch to ALL soon for compile testing.

Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since we no longer need to guard against access from hardware interrupt handlers. Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the child process share the parent's lock so that signal state may be kept in sync. Partially addresses PR kern/37437.

Network protocol interrupts can now block on locks, so merge the globals proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock). Implications: - Inspecting process state requires thread context, so signals can no longer be sent from a hardware interrupt handler. Signal activity must be deferred to a soft interrupt or kthread. - As the proc state locking is simplified, it's now safe to take exit() and wait() out from under kernel_lock. - The system spends less time at IPL_SCHED, and there is less lock activity.

Add PaX ASLR (Address Space Layout Randomization) [from elad and myself]
For regular (non PIE) executables randomization is enabled for:
1. The data segment
2. The stack
For PIE executables(*) randomization is enabled for:
1. The program itself
2. All shared libraries
3. The data segment
4. The stack
(*) To generate a PIE executable:
- compile everything with -fPIC
- link with -shared-libgcc -Wl,-pie
This feature is experimental, and might change. To use selectively add
options PAX_ASLR=0
in your kernel.
Currently we are using 12 bits for the stack, program, and data segment and
16 or 24 bits for mmap, depending on __LP64__.

- Increase the number of thread priorities from 128 to 256. How the space is set up is to be revisited. - Implement soft interrupts as kernel threads. A generic implementation is provided, with hooks for fast-path MD code that can run the interrupt threads over the top of other threads executing in the kernel. - Split vnode::v_flag into three fields, depending on how the flag is locked (by the interlock, by the vnode lock, by the file system). - Miscellaneous locking fixes and improvements.

Check for this and return EINVAL if not; this gives a cheap test for corrupted ucontexts eg on a signal handler stack which would go unnoticed otherwise. -Don't ckeck for NULL ucontext pointers explicitely.

Implement a few changes needed to properly resolve PR#30924, as discussed in the PR. - introduce sys/timevar.h to hold kernel-specific stuff relevant to sys/time.h. Ideally, timevar.h would contain all (or almost) of the #ifdef _KERNEL part of time.h, but that's a pretty big and tedious change to make. For now, it will contain only the prototypes I introduced when working on COMPAT_NETBSD32. - split copyinout_t into copyin_t and copyout_t, it makes prototypes more explicit about the meaning of a given argument. Suggested by yamt@. - move copyinout_t definition in sys/time.h to systm.h as copyin_t and copyout_t - make everything uses the new types and include the proper headers at the proper places.

avoid calling into the pool code while holding sched_lock since both pool_get() and pool_put() can call wakeup(). instead, allocate the struct sadata_upcall before taking sched_lock in mi_switch() and free it after releasing sched_lock. clean up some modularity warts by adding a callback to struct sadata_upcall for freeing sa_arg.

Rework the coredump code to have no explicit knownledge of how coredump
i/o is done. Instead, pass an opaque cookie which is then passed to a
new routine, coredump_write, which does the actual i/o. This allows the
method of doing i/o to change without affecting any future MD code.
Also, make netbsd32_core.c [re]use core_netbsd.c (in a similar manner that
core_elf64.c uses core_elf32.c) and eliminate that code duplication.
cpu_coredump{,32} is now called twice, first with a NULL iocookie to fill
the core structure and a second to actually write md parts of the coredump.
All i/o is nolonger random access and is suitable for shipping over a stream.

Move the sigfilter hook to a more adequate location, and rename it to better fit what it does. The softsignal feature is used in Darwin to trace processes. When the traced process gets a signal, this raises an exception. The debugger will receive the exception message, use ptrace with PT_THUPDATE to pass the signal to the child or discard it, and then it will send a reply to the exception message, to resume the child. With the hook at the beginnng of kpsignal2, we are in the context of the signal sender, which can be the kill(1) command, for instance. We cannot afford to sleep until the debugger tells us if the signal should be delivered or not. Therefore, the hook to generate the Mach exception must be in the traced process context. That was we can sleep awaiting for the debugger opinion about the signal, this is not a problem. The hook is hence located into issignal, at the place where normally SIGCHILD is sent to the debugger, whereas the traced process is stopped. If the hook returns 0, we bypass thoses operations, the Mach exception mecanism will take care of notifying the debugger (through a Mach exception), and stop the faulting thread.

Add a sigfilter emulation hook. It is used at the beginning of kpsignal2() so that a specific emulation has the oportunity to filter out some signals. if sigfilter returns 0, then no signal is sent by kpsignal2(). There is another place where signals can be generated: trapsignal. Since this function is already an emulation hook, no call to the sigfilter hook was introduced in trapsignal. This is needed to emulate the softsignal feature in COMPAT_DARWIN (signals sent as Mach exception messages)

Cleanup signal delivery for SA processes: General idea: only consider the LWP on the VP for signal delivery, all other LWPs are either asleep or running from waking up until repossessing the VP. - in kern_sig.c:kpsignal2: handle all states the LWP on the VP can be in - in kern_sig.c:proc_stop: only try to stop the LWP on the VP. All other LWPs will suspend in sa_vp_repossess() until the VP-LWP donates the VP. Restore original behaviour (before SA-specific hacks were added) for non-SA processes. - in kern_sig.c:proc_unstop: only return the LWP on the VP - handle sa_yield as case 0 in sa_switch instead of clearing L_SA, add an L_SA_YIELD flag - replace sa_idle by L_SA_IDLE flag since it was either NULL or == sa_vp Also don't output itimerfire overrun warning if the process is already exiting. Also g/c sa_woken because it's not used. Also g/c some #if 0 code.

Add the gating of system calls that cause modifications to the underlying file system. The function vfs_write_suspend stops all new write operations to a file system, allows any file system modifying system calls already in progress to complete, then sync's the file system to disk and returns. The function vfs_write_resume allows the suspended write operations to complete. From FreeBSD with slight modifications. Approved by: Frank van der Linden <fvdl@netbsd.org>

* Shuffle some data structures so, and add a flags word to ksiginfo_t. Right now the only flag is used to indicate if a ksiginfo_t is a result of a trap. Add a predicate macro to test for this flag. * Add initialization macros for ksiginfo_t's. * Add accssor macro for ksi_trap. Expands to 0 if the ksiginfo_t was not the result of a trap. This matches the sigcontext trapcode semantics. * In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal. Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles the case of non-trap-generated signals that have a > 0 si_code. This patch fixes a signal delivery problem with threaded programs noted by Matthias Drochner on tech-kern. As discussed on tech-kern. Reviewed and OK's by Christos.

handle siginfo for deferred signals. Allocate a ksiginfo pool, and store the information there. TODO: 1. since timer stuff gets called from an interrupt context, we could preallocate ksiginfo_t's from the pool, so we don't need a kmem pool. 2. probably the sa signal delivery syscall can be changed to take a ksiginfo_t so we can use only one pool. 3. maybe when we add realtime signal support, add a resource limit on the number of ksiginfo_t's a process can allocate.

SA fixes from Stephan Uphoff. Quoting him: The patch below (hopefully) improves some signaling problems found by Nathan. It also contains some cleanup of the sa_upcall_userret() function removing any sleep calls using PCATCH. Unblocked threads now only use an upcall stack after they acquire the virtual CPU. This prevents unblocked threads from stealing all available upcall stacks. Tested by Nick Hudson.

Two fixes: * Change the semantics of proc_unstop() slightly, so that it is responsible for making all stopped LWPs runnable, instead of all-but-one. Return value is a LWP that can be interrupted if doing so is necessary to take a signal. Adjust callers of proc_stop() to the new, simpler semantics. * When a non-continue signal is delivered to a stopped process and there is a LWP sleeping interruptably, call setrunnable() (by way of the 'out:' target in psignal1) instead of calling unsleep() so that it becomes LSSTOP in issignal() and continuable by proc_unstop().

In sigexit(), call the userret hook instead of assuming it's our coredump hook; calling the coredump hook when the process has made it to exit1() is counterproductive. Clear P_SA in p->p_flag as well as L_SA in l_flag to avoid problems with the signal code when we're exiting.

Separate the scheduler from the context switching code. This is done by adding an extra argument to mi_switch() and cpu_switch() which specifies the new process. If NULL is passed, then the new function chooseproc() is invoked to wait for a new process to appear on the run queue. Also provides an opportunity for optimisations if "switching to self". Also added are C versions of the setrunqueue() and remrunqueue() low-level primitives if __HAVE_MD_RUNQUEUE is not defined by MD code. All these changes are contingent upon the __HAVE_CHOOSEPROC flag being defined by MD code to indicate that cpu_switch() supports the changes.

Alter the handling of stopping multi-LWP processes: Instead of setting the state of LSSLEEP lwps to LSSTOP, arrange for them to notice the process state in issignal(), so that LWPs only stop at the user/kernel boundary. This avoids some sticky situations, for example, with the NFS recieve lock, and is conceptually cleaner.

Add kernel support for having userland provide the signal trampoline: * struct sigacts gets a new sigact_sigdesc structure, which has the sigaction and the trampoline/version. Version 0 means "legacy kernel provided trampoline". Other versions are coordinated with machine- dependent code in libc. * sigaction1() grows two more arguments -- the trampoline pointer and the trampoline version. * A new __sigaction_sigtramp() system call is provided to register a trampoline along with a signal handler. * The handler is no longer passed to sensig() functions. Instead, sendsig() looks up the handler by peeking in the sigacts for the process getting the signal (since it has to look in there for the trampoline anyway). * Native sendsig() functions now select the appropriate trampoline and its arguments based on the trampoline version in the sigacts. Changes to libc to use the new facility will be checked in later. Kernel version not bumped; we will ride the 1.6C bump made recently.

Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (*de*referencing curproc is another story, but that's always been true).

Allow stop signals to act on processes whose LWPs are all sleeping uninterruptably. Suspend LWPs in a process dumping core, rather than simply clearing the L_DETACHED flag; their trap frames, and therefore kernel stacks, need to stick around until coredump() gets around to writing them out.

Setting P_WEXIT in sigexit() isn't enough anymore; we have to also set a userret handler. Fixes some annoying crashes when core dumping multi-LWP processes across NFS. This also lets us un-detach LWPs so that they can't be reaped before coredump gets a chance to dump their state.

- Centralize p_nrlwps handling in those functions which actually set the LWP state to LSRUN. Simplifies matters considerably. - Trying to keep track of the preempted LWP was a bad idea; go back to searching for now. - Send a PREEMPTED upcall from proc_unstop(), so that stopped processes know that something happened, and so that all runnable LWPs of a unstopped process have an upcall to deliver (Ideally, the LWP that was runnable when the process was stopped should return first, and any LWPs that were woken up while the process was stopped would interrupt it, but that's difficult to arrange).

Pool deals fairly well with physical memory shortage, but it doesn't deal with shortages of the VM maps where the backing pages are mapped (usually kmem_map). Try to deal with this: * Group all information about the backend allocator for a pool in a separate structure. The pool references this structure, rather than the individual fields. * Change the pool_init() API accordingly, and adjust all callers. * Link all pools using the same backend allocator on a list. * The backend allocator is responsible for waiting for physical memory to become available, but will still fail if it cannot callocate KVA space for the pages. If this happens, carefully drain all pools using the same backend allocator, so that some KVA space can be freed. * Change pool_reclaim() to indicate if it actually succeeded in freeing some pages, and use that information to make draining easier and more efficient. * Get rid of PR_URGENT. There was only one use of it, and it could be dealt with by the caller. From art@openbsd.org.

PR/14795: Christos Zoulas: Fix locking problem on MP systems where ltsleep() is calling CURSIG() which can call issignal() and issignal() could not deal with being called from a locked context. This happens when a process receives SIGTTIN, and issignal() calls psignal() to post SIGCHLD to the parent. XXX: It is really messy to have issignal() handle the job control functionality and the whole signal interlocking protocol needs to be re-designed. For now this fix (provided by enami) does the trick. I've been running with this fix for weeks, and atatat has stress-tested the kernel running ~30 make kernels...

Reduce use of curproc in several places: - Change ktrace interface to pass in the current process, rather than p->p_tracep, since the various ktr* function need curproc anyway. - Add curproc as a parameter to mi_switch() since all callers had it handy anyway. - Add a second proc argument for inferior() since callers all had curproc handy. Also, miscellaneous cleanups in ktrace: - ktrace now always uses file-based, rather than vnode-based I/O (simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD. Do non-blocking I/O, and yield a finite number of times when receiving EWOULDBLOCK before giving up. - move code duplicated between sys_fktrace and sys_ktrace into ktrace_common. - simplify interface to ktrwrite()

Add kernel logging of processes which exit on signals which can cause a core to drop, and whether the core dropped, or, if it did not, why not (i.e. error number). Logs process ID, name, signal that hit it, and whether the core dump was successful. logging only happens if kern_logsigexit is non-zero, and it can be changed by the new sysctl(3) value KERN_LOGSIGEXIT. The name of this sysctl and its function are taken from FreeBSD, at the suggestion of Greg Woods in PR 6224. Default behavior is zero for a normal kernel, and one for a kernel compiled with DIAGNOSTIC.

Remplace kern.shortcorename sysctl with a more flexible sheme, core filename format, which allow to change the name of the core dump, and to relocate it in a directory. Credits to Bill Sommerfeld for giving me the idea :) The default core filename format can be changed by options DEFCORENAME and/or kern.defcorename Create a new sysctl tree, proc, which holds per-process values (for now the corename format, and resources limits). Process is designed by its pid at the second level name. These values are inherited on fork, and the corename fomat is reset to defcorename on suid/sgid exec. Create a p_sugid() function, to take appropriate actions on suid/sgid exec (for now set the P_SUGID flag and reset the per-proc corename). Adjust dosetrlimit() to allow changing limits of one proc by another, with credential controls.

Add a read/write lock to the proclists and PID hash table. Use the write lock when doing PID allocation, and during the process exit path. Use a read lock every where else, including within schedcpu() (interrupt context). Note that holding the write lock implies blocking schedcpu() from running (blocks softclock). PID allocation is now MP-safe. Note this actually fixes a bug on single processor systems that was probably extremely difficult to tickle; it was possible that schedcpu() would run off a bad pointer if the right clock interrupt happened to come in the middle of a LIST_INSERT_HEAD() or LIST_REMOVE() to/from allproc.

Rework the process exit path, in preparation for making process exit and PID allocation MP-safe. A new process state is added: SDEAD. This state indicates that a process is dead, but not yet a zombie (has not yet been processed by the process reaper). SDEAD processes exist on both the zombproc list (via p_list) and deadproc (via p_hash; the proc has been removed from the pidhash earlier in the exit path). When the reaper deals with a process, it changes the state to SZOMB, so that wait4 can process it. Add a P_ZOMBIE() macro, which treats a proc in SZOMB or SDEAD as a zombie, and update various parts of the kernel to reflect the new state.

(Avoids uses the stackgap crap for these system calls.) * Add a new flag (p_checksig) to indicate that a process may have signals pending and userret() needs to do the full (slow) check. * Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE. * Correct emulation bugs with restoring SS_ONSTACK. * Make the signal mask in the sigcontext always use the emulated mask format. * Store signals internally in sigaction structures, rather than maintaining a bunch of little sigsets for each SA_* bit. * Keep track of where we put the signal trampoline, rather than figuring it out in *_sendsig(). * Issue a warning when a non-emulated sigaction bit is observed. * Add missing emulated signals, and a native SIGPWR (currently not used). * Implement the `not reset when caught' semantics for relevant signals. Note: Only code touched by the i386 port has been modified. Other ports and emulations need to be updated.

Significantly restructure the way signal state for a process is stored. Rather than using bitmasks to redundantly store the information kept in the process's sigacts (because the sigacts was kept in the u-area), hang sigacts directly off the process, and access it directly. Simplify signal setup code tremendously by storing information in the sigacts as an array of struct sigactions, rather than in a different format, since userspace uses sigactions. Make sigacts sharable by adding reference counting.

lots of changes: prototype migration, move lots of variables, definitions, and structure elements around. kill some unnecessary type and macro definitions. standardize clock handling. More changes than you'd want.

I suppose a SIGKILL or SIGTERM should make a process go about its business fast. But the previous situation would allow "sigblock(sigmask(SIGTERM)); kill(SIGTERM)" to thwart priority policies.

Make all files using spl*() #include cpu.h. Changes from trunk. init_main.c: New method of pseudo-device of initialization. kern_clock.c: hardclock() and softclock() now take a pointer to a clockframe. softclock() only does callouts. kern_synch.c: Remove spurious declaration of endtsleep(). Adjust uses of averunnable for new struct loadav. subr_prf.c: Allow printf() formats in panic(). tty.c: averunnable changes. vfs_subr.c: va_size and va_bytes are now quads.

init_main.c: clock changes from 4.4; initclocks() is called after vfsinit(). No startrtclock() or enablertclock(). Some pseudo-device cruft, but this needs to be updated. kern_clock.c: from 4.4: gatherstats() --> statclock(). statclock(), hardclock(), and softclock() take a `struct clockframe *'. New initclocks(), harclock(), statclock(), startprofclock(), and stopprofclock(). kern_synch.c: from 4.4: machine-independent swtch(), which is now where process time is integrated. Calls cpu_swtch() with the current process as an arg. subr_autoconf.c: Fix typo. subr_prf.c: msgbufp and msgbufmapped are define in machdep.c tty.c: Make TIOCHPCL #ifdef COMPAT_43. Incorporate changes from main branch.

These changes are due to a mismatch with user functions prototyped as func(short) and the fact the the kernel uses full ints. This caused problems on the pc532 port. These fixes take the good 16 bits passed by the user program and converts them into the correct form for the kernel.

the swtch() calls here should not need to be splclock() protected, and certainly don't need to be bracketed by splclock()/splnone(), the latter of which is a jolitz invention.
