Delete the msyscall mechanism entirely, since mimmutable+pinsyscalls has
replaced it with a more strict mechanism, which happens to be lockless O(1)
rather than micro-lock O(1)+O(log N).  Also nop-out the sys_msyscall(2) guts,
but leave the syscall around for a bit longer so that people can build through
it, since ld.so(1) still wants to call it.

Implement per-CPU caching for the page table page (vp) pool and the PTE
descriptor (pted) pool in the arm64 pmap implementation.  This
significantly reduces the side-effects of lock contention on the kernel
map lock that is (incorrectly) translated into excessive page daemon
wakeups.  This is not a perfect solution but it does lead to significant
speedups on machines with many CPU cores.

This requires adding a new pmap_init_percpu() function that gets called
at the point where kernel is ready to set up the per-CPU pool caches.
Dummy implementations of this function are added for all non-arm64
architectures.  Some other architectures can probably benefit from
providing an actual implementation that sets up per-CPU caches for
pmap pools as well.

Remove p_rtime from struct proc and replace it by passing the timespec
as argument to the tuagg_locked function.

- Remove incorrect use of p_rtime in other parts of the tree. p_rtime was
almost always 0 so including it in any sum did not alter the result.
- In main() the update of time can be further simplified since at that time
only the primary cpu is running.
- Add missing nanouptime() call in cpu_hatch() for hppa
- Rename tuagg_unlocked to tuagg_locked like it is done in the rest of

Move the clockqueue_init() call out of clockintr_cpu_init() and up

This will allow sched_init_cpu() to allocate clockintr handles for a

Add support for per-cpu event counters, to be used for clock and IPI
counters where the event being counted occurs across all CPUs in the
system.  Counter instances can be made per-cpu by calling evcount_percpu()
after the counter is attached, and this can occur before or after all system
CPUs are attached.  Per-cpu counter instances should be incremented using
evcount_inc().

Simplfity setregs() by passing it the ps_strings and switching
sys_execve() to return EJUSTRETURN.

setregs() is the MD routine used by sys_execve() to set up the
thread's trapframe and PCB such that, on 'return' to userspace, it
has the register values defined by the ABI and otherwise zero.  It
had to set the syscall retval[] values previously because the normal
syscall return path overwrites a couple registers with the retval[]
values.  By instead returning EJUSTRETURN that and some complexity
with program-counter handling on m88k and sparc64 goes away.

Also, give setregs() add a 'struct ps_strings *arginfo' argument
so powerpc, powerpc64, and sh can directly get argc/argv/envp
values for registers instead of copyin()ing the one in userspace.

kernel: remove global "randompid" toggle

Apparently, we used to created several kthreads before the kernel
random number generator was up and running.  A toggle, "randompid",
was needed to tell allocpid() whether it made sense to attempt to
allocate random PIDs.

However, these days we get e.g. arc4random(9) into a working state
before any kthreads are spawned, so the toggle is no longer needed.

Enable pool cache on knote pool

Use the pool cache to reduce the overhead of memory management in
function kqueue_register().

When EV_ADD is given, kqueue_register() pre-allocates a knote to avoid
potential sleeping in the middle of the critical section that spans
from knote lookup to insertion. However, the pre-allocation is useless
if the lookup finds a matching knote.

The cost of knote allocation will become significant with kqueue-based
poll(2) and select(2) because the frequency of allocation will increase.
Most of the cost appears to come from the locking inside the pool.
The pool cache amortizes it by using CPU-local caches of free knotes
as buffers.

Start the SMR thread when all CPUs are ready for scheduling. This
prevents the appearance of a "smr: dispatch took N seconds" message
during boot when there is an early smr_call(). Such a call can happen
with mfii(4). The initial dispatch cannot make progress until
smr_grace_wait() can visit all CPUs.

This fix is essentially a hack. It makes use of the fact that there
is no hard guarantee on how quickly the callback of smr_call() gets
invoked. It is assumed that the SMR call backlog does not grow large
during boot.

An alternative fix is to make smr_grace_wait() skip secondary CPUs
until they have been started. However, this could break if the spinup
logic of secondary CPUs was changed.

Repurpose the "syscalls must be on a writeable page" mechanism to
enforce a new policy: system calls must be in pre-registered regions.
We have discussed more strict checks than this, but none satisfy the
cost/benefit based upon our understanding of attack methods, anyways
let's see what the next iteration looks like.

This is intended to harden (translation: attackers must put extra
effort into attacking) against a mixture of W^X failures and JIT bugs
which allow syscall misinterpretation, especially in environments with
polymorphic-instruction/variable-sized instructions.  It fits in a bit
with libc/libcrypto/ld.so random relink on boot and no-restart-at-crash
behaviour, particularily for remote problems. Less effective once on-host
since someone the libraries can be read.

For static-executables the kernel registers the main program's
PIE-mapped exec section valid, as well as the randomly-placed sigtramp
page.  For dynamic executables ELF ld.so's exec segment is also
labelled valid; ld.so then has enough information to register libc's
exec section as valid via call-once msyscall(2)

For dynamic binaries, we continue to to permit the main program exec
segment because "go" (and potentially a few other applications) have
embedded system calls in the main program.  Hopefully at least go gets
fixed soon.

We declare the concept of embedded syscalls a bad idea for numerous
reasons, as we notice the ecosystem has many of
static-syscall-in-base-binary which are dynamically linked against
libraries which in turn use libc, which contains another set of
syscall stubs.  We've been concerned about adding even one additional
syscall entry point... but go's approach tends to double the entry-point
attack surface.

This was started at a nano-hackathon in Bob Beck's basement 2 weeks
ago during a long discussion with mortimer trying to hide from the SSL
scream-conversations, and finished in more comfortable circumstances
next to a wood-stove at Elk Lakes cabin with UVM scream-conversations.

Introduce safe memory reclamation, a mechanism for reclaiming shared
objects that readers can access without locking. This provides a basis
for read-copy-update operations.

Readers access SMR-protected shared objects inside SMR read-side
critical section where sleeping is not allowed. To reclaim
an SMR-protected object, the writer has to ensure mutual exclusion of
other writers, remove the object's shared reference and wait until
read-side references cannot exist any longer. As an alternative to
waiting, the writer can schedule a callback that gets invoked when
reclamation is safe.

The mechanism relies on CPU quiescent states to determine when an
SMR-protected object is ready for reclamation.

The <sys/smr.h> header additionally provides an implementation of
singly- and doubly-linked lists that can be used together with SMR.
These lists allow lockless read access with a concurrent writer.

Move boottime into the timehands.

To protect the timehands we first need to protect the basis for all UTC
time in the kernel: the boottime.

Because the boottime can be changed at any time it needs to be versioned
along with the other members of the timehands to enable safe lockless reads
when using it for anything.  So the global boottime timespec goes away and
the static boottimebin becomes a member of the timehands.  Instead of reading
the global boottime you use one of two interfaces: binboottime(9) or
microboottime(9). nanoboottime(9) can trivially be added later, though there
are no consumers for it at the moment.

This introduces one small change in behavior.  We used to advance the
reported boottime just before launching kernel threads from main().
This makes it look to userland like we "booted" moments before those
threads were launched.  Because there is no longer a boottime global we
can no longer trivially do this from main(), so the boottime we report
to userspace via e.g. kern.boottime will now reflect whatever the time
was when we bootstrapped the timehands via inittodr(9).  This is usually
no more than a minute before the kernel threads are launched from main().
The prior behavior can be restored by adding a new interface to the
timecounter layer in a future commit.

Based on FreeBSD r303387.

Discussed with mpi@ and visa@.

Simplify the startup of the cleaner, reaper and update threads by
passing the main function directly to kthread_create(9). The start_*
functions are mere stepping stones nowadays and can be pruned.
They used to contain more logic in the pre-kthread era.

While here, set `cleanerproc' and `syncerproc' during the thread
creation rather than expect the threads to set the proc pointer.
Also, rename `sched_sync' to `syncer_thread' to reduce confusion
with the scheduler-related functions.

Implement MAP_STACK option for mmap().  Synchronous faults (pagefault and
syscall) confirm the stack register points at MAP_STACK memory, otherwise
SIGSEGV is delivered. sigaltstack() and pthread_attr_setstack() are modified
to create a MAP_STACK sub-region which satisfies alignment requirements.
Observe that MAP_STACK can only be set/cleared by mmap(), which zeroes the
contents of the region -- there is no mprotect() equivalent operation, so
there is no MAP_STACK-adding gadget.
This opportunistic software-emulation of a stack protection bit makes
stack-pivot operations during ROPchain fragile (kind of like removing a
tool from the toolbox).

Automatically create a default lo(4) interface per rdomain.

In order to stop abusing lo0 for all rdomains, a new loopback interface
will be created every time a rdomain is created.  The unit number will
be the same as the rdomain, i.e. lo1 will be attached to rdomain 1.

If this loopback interface is already in use it wont be possible to create
the corresponding rdomain.

In order to know which lo(4) interface is attached to a rdomain, its index
is stored in the rtable/rdomain map.

This is a long overdue since the introduction of rtable/rdomain.  It also
fixes a recent regression due to resetting the rdomain of an incoming
packet reported by semarie@, Andreas Bartelt and Nils Frohberg.

add generalised access to per cpu data structures and counters.

both the cpumem and counters api simply allocates memory for each cpu in
the system that can be used for arbitrary per cpu data (via cpumem), or
a versioned set of counters per cpu (counters).

there is an alternate backend for uniprocessor systems that basically
turns the percpu data access into an immediate access to a single
allocation.

there is also support for percpu data structures that are available at
boot time by providing an allocation for the boot cpu. after autoconf,
these allocations have to be resized to provide for all cpus that were
enumerated by boot.

Initialize the routing table before domains.

The routing table is not an optional component of the network stack
and initializing it inside the "routing domain" requires some ugly
introspection in the domain interface.

This put the rtable* layer at the same level of the if* level.  These
two subsystem are organized around the two global data structure used
in the network stack:

- the global &ifnet list, to be used in process context only, and
- the routing table which can be read in interrupt context.

This change makes the rtable_* layer domain-aware and extends the
"struct domain" such that INET, INET6 and MPLS can specify the length
of the binary key used in lookups.  This allows us to keep, or move
towards, AF-free route and rtable layers.

While here stop the madness and pass the size of the maximum key length
in *byte* to rn_inithead0().

introduce srp, which according to the manpage i wrote is short for
"shared reference pointers".

srp allows concurrent access to a data structure by multiple cpus
while avoiding interlocking cpu opcodes. it manages its own reference
counts and the garbage collection of those data structure to avoid
use after frees.

internally srp is a twisted version of hazard pointers, which are
a relative of RCU.

jmatthew wrote the bulk of a hazard pointer implementation and
changed bpf to use it to allow mpsafe access to bpfilters. however,
at s2k15 we were trying to apply it to other data structures but
the memory overhead of every hazard pointer would have blown out
significantly in several uses cases. a bulk of our time at s2k15
was spent reworking hazard pointers into srp.

this diff adds the srp api and adds the necessary metadata to struct
cpuinfo on our MP architectures. srp on uniprocessor platforms has
alternate code that is optimised because it knows there'll be no
concurrent access to data by multiple cpus.

srp is made available to the system via param.h, so it should be
available everywhere in the kernel.

the docs likely need improvement cos im too close to the implementation.

emul_native is only used for kernel threads which can't dump core, so
delete coredump_trad(), uvm_coredump(), cpu_coredump(), struct md_coredump,
and various #includes that are superfluous.

This leaves compat_linux processes without a coredump callback.  If that
ability is desired, someone should update it to use coredump_elf32() and
verify the results...

introduce a garbage collector for (very) idle pool pages.

now that idle pool pages are timestamped we can tell how long theyve
been idle. this adds a task that runs every second that iterates
over all the pools looking for pages that have been idle for 8
seconds so it can free them.

this idea probably came from a conversation with tedu@ months ago.

Introduce a thread for zeroing pages without holding the kernel lock.  This
way we can do some useful kernel lock in parallel with other things and create
a reservoir of zeroed pages ready for use elsewhere.  This should reduce
latency.  The thread runs at the absolutel lowest priority such that we don't
keep other kernel threads or userland from doing useful work.

Can be easily disabled by disabling the kthread_create(9) call in main().
Which perhaps we should do for non-MP kernels.

introduce tasks and taskqs as an alternative to workqs.

tasks are modelled on the timeout api, so users familiar with
timeout_set, timeout_add, and timeout_del will already know what
to expect from task_set, task_add, and task_del.

i wrote this because workq_add_task can fail in the place you
actually need it, and there arent any good ways of recovering at
that point.  workq_queue_task was added to try and help, but required
external state to be stored for users of that api to know whether
something was already queued or not.

workqs also didnt provide a way to cancel or remove work.

this has been percolating with a bunch of people. putting it in as i
wrote it so i can apply their feedback to the code with the history kept
in cvs.

move attach mpath before any hardware. the benefits being:

- the mpath hooks path drivers call dont have to parse autoconf
structures to tell if mpath may attach in the future. it now either
has already attached or never will, which is simpler to check.

- i can get rid of the global mpath target array by moving it into
the mpath softc because of the above.

- makes reasoning about state transitions (especially around when
to attach) when groups of paths are implemented a lot simpler

the only real caveat is dmesg feng shui may be ruined. i can come
back and look at this after i move mpath itself forward though.

executable and DSO (via crtbegin.c/crtbeginS.c).  Not used yet, but
needed before GCC can start emitting -fstack-protector code that uses

Make context switching much more MI:
 - Move the functionality of choosing a process from cpu_switch into
   a much simpler function: cpu_switchto. Instead of having the locore
   code walk the run queues, let the MI code choose the process we
   want to run and only implement the context switching itself in MD
   code.
 - Let MD context switching run without worrying about spls or locks.
 - Instead of having the idle loop implemented with special contexts
   in MD code, implement one idle proc for each cpu. make the idle
   loop MI with MD hooks.
 - Change the proc lists from the old style vax queues to TAILQs.
 - Change the sleep queue from vax queues to TAILQs. This makes
   wakeup() go from O(n^2) to O(n)

Introduce a md pmap hook, pmap_remove_holes(), which is supposed to mark
the holes a MMU may have from a given vm_map. This will be automagically
invoked for newly created vmspaces.

On platforms with MMU holes (e.g. sun4, sun4c and vax), this prevents
mmap(2) hints which would end up being in the hole to be accepted as valid,
causing unexpected signals when the process tries to access the hole
(since pmap can not fill the hole anyway).

Unfortunately, the logic mmap() uses to pick a valid address for anonymous
mappings needs work, as it will only try to find an address higher than the
hint, which causes all mmap() with a hint in the hole to fail on vax. This
will be improved later.

Since p_flag is often manipulated in interrupts and without biglock
it's a good idea to use atomic.h operations on it. This mechanic
change updates all bit operations on p_flag to atomic_{set,clear}bits_int.

Only exception is that P_OWEUPC is set by MI code before calling
need_proftick and it's automatically cleared by ADDUPC. There's
no reason for MD handling of that flag since everyone handles it the

Kernel stack can be swapped. This means that stuff that's on the stack
should never be referenced outside the context of the process to which
this stack belongs unless we do the PHOLD/PRELE dance. Loads of code
doesn't follow the rules here. Instead of trying to track down all
offenders and fix this hairy situation, it makes much more sense
to not swap kernel stacks.

From art@, tested by many some time ago.

Create the init process earlier, before the root filesystem is mounted,
and have it stall on a semaphore. This allows all kthread creations which
could have been requested during autoconf to be processed before root
is mounted as well.

This causes umass devices attached to any usb with flags 1 (such as on macppc)
to configure properly instead of panicing the kernel at mountroot time.

From NetBSD; tested by various.

This touches only MI code, and adds new time keeping code.  The
code is all conditionalized on __HAVE_TIMECOUNTER, and not
enabled on any platforms.

adjtime(2) support exists, courtesy of nordin@, sysctl(2) support
and a concept of quality for each time source attached exists.

High quality time sources exists for PIIX4 ACPI timer as well as
some AMD power management chips.  This will have to be redone
once we actually add ACPI support (at that time we need to use
the ACPI interfaces to get at these clocks).

This moves access to wall and uptime variables in MI code,
encapsulating all such access into wall-defined functions
that makes sure locking is done as needed.

It also cleans up some uses of wall time vs. uptime some
places, but there is sure to be more of these needed as
well, particularily in MD code.  Also, many current calls
to microtime() should probably be changed to getmicrotime(),
or to the {,get}microuptime() versions.

Go back to defining simplelocks as noops, even if MULTIPROCESSOR.  Instead use
a new real simple recursive-lock capable lock implementation for the few
necessary locks (kernel, scheduler, tlb shootdown, printf and ddb MP).
This because we cannot trust the old fine-grained locks spread out all over
our kernel, and not really tested.

Yet another sync to NetBSD uvm.
Today we add a pmap argument to pmap_update() and allocate map entries for
kernel_map from kmem_map instead of using the static entries. This should
get rid of MAX_KMAPENT panics. Also some uvm_loan problems are fixed.

Count pages not buffers. This fixes deadlock condition which mainly
occurs on the fs with large block size. We can have situation where
numcleanbufs < locleanbufs and numdirtybufs < hidirtybufs.  So, buffer
flushing daemon never wakeups and other processes asleep forever waiting
for a clean buffers. We count pages only for the dirty buffers which are
on freelist(BQ_DIRTY).

 The first implementation of the buffer flushing daemon. It solves our
problem when syncer can't do its work because of vnode locks (PR1983).
This also solves our problem where bigger number of buffers results in a
much worse perfomance. In my configuration (i386, 128mb, BUFCACHEPERCENT=35)
this speedup tar -xzf ports.tar.gz in 2-4 times. In configuration with
low number of buffers and softupdates this may slowdown some operations
up to 15%.

 The major difference with current buffer cache is that new implementation
uses separate queues for dirty and clean buffers. I.e. BQ_LRU and BQ_AGE
replaced by BQ_CLEAN and BQ_DIRTY. This simplifies things a lot and
doesn't affect perfomance in a bad manner.

Thanks to art and costa for pointing on errors.

Tested by brad, millert, naddy, art, jj, camield

Cryptographic services framework, and software "device driver". The
idea is to support various cryptographic hardware accelerators (which
may be (detachable) cards, secondary/tertiary/etc processors,
software crypto, etc). Supports session migration between crypto
devices. What it doesn't (yet) support:
 - multiple instances of the same algorithm used in the same session
 - use of multiple crypto drivers in the same session
 - asymmetric crypto

No support for a userland device yet.

IPsec code path modified to allow for asynchronous cryptography
(callbacks used in both input and output processing). Some unrelated
code simplification done in the process (especially for AH).

Development of this code kindly supported by Network Security
Technologies (NSTI). The code was writen mostly in Greece, and is
being committed from Montreal.

Merge of MACHINE_NEW_CONTIG (aka MNN) code from Chuck Cranor,
<chuck@openbsd.org>. This code is as of yet disabled on all platforms,
actually not yet supported on more than mvme68k, although other
platforms are expected soon, as code is already available.
This code makes handling of multiple physical memory regions
consistent over all platforms, as well as keeping the performance of
maintaining a single continuous memory chunk.  It is also a
requirement for the upcoming UVM replacement VM system.

What I did in this merge: just declared the pmap_map function in a
MD include file per port that needs it.  It's not an exported pmap
interface, says Chuck.  It ended up in differnt include files on
differnet ports, as I tried to follow the current policy on a per-arch
basis.

Make sure config_init gets called before consinit, as at least one port
actually uses config_* functions for console attachment.  Document
config_init should not call malloc as the move was over the mem-init
function calls too.

from netbsd;
New generic disk framework.  Highlights:
New metrics handling.  Metrics are now kept in the new `struct disk'.
Busy time is now stored as a timeval, and transfer count in bytes.
Storage for disklabels is now dynamically allocated, so that the size
of the disk structure is not machine-dependent.
Several new functions for attaching and detaching disks, and handling
metrics calculation.
Old-style instrumentation is still supported in drivers that did it
before.  However, old-style instrumentation is being deprecated, and
will go away once the userland utilities are updated for the new
framework.
For usage and architectural details, see the forthcoming disk(9)
manual page.
