Rework posix_spawn locking and memory management: - always provide a vmspace for the new proc, initially borrowing from proc0 (this part fixes PR 46286) - increase parallelism between parent and child if arguments allow this, avoiding a potential deadlock on exec_lock - add a new flag for userland to request old (lockstepped) behaviour for better error reporting - adapt test cases to the previous two and add a new variant to test the diagnostics flag - fix a few memory (and lock) leaks - provide netbsd32 compat

Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.

Add support for cpu-specific uarea allocation routines. Allows different allocation for user and system lwps. MIPS will use this to map uareas of system lwp used direct-mapped addresses (to reduce the overhead of switching to kernel threads). ibm4xx could use to map uareas via direct mapped addresses and avoid the problem of having the kernel stack not in the TLB.

- Merge sched_pstats() and uvm_meter()/uvm_loadav(). Avoids double loop through all LWPs and duplicate locking overhead. - Move sched_pstats() from soft-interrupt context to process 0 main loop. Avoids blocking effect on real-time threads. Mostly fixes PR/38792. Note: it might be worth to move the loop above PRI_PGDAEMON. Also, sched_pstats() might be cleaned-up slightly.

Remove uarea swap-out functionality: - Addresses the issue described in PR/38828. - Some simplification in threading and sleepq subsystems. - Eliminates pmap_collect() and, as a side note, allows pmap optimisations. - Eliminates XS_CTL_DATA_ONSTACK in scsipi code. - Avoids few scans on LWP list and thus potentially long holds of proc_lock. - Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k. - Removes __SWAP_BROKEN cases. Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on acorn26 (thanks to <bjh21>). Discussed on <tech-kern>, reviewed by <ad>.

Only swapout uareas if VMSWAP_UAREA is defined (which is should be by default). If it's not defined and PMAP_MAP_POOLPAGE is defined and USPACE == PAGE_SIZE, then allocate/map USPACE via uvm_pagealloc/PMAP_MAP_POOLPAGE. On platforms like MIPS with 16KB pages, this means that uareas (and hence lwp kernel stacks) will be always be accessible since they will be KSEG0.

Ephemeral mapping (emap) implementation. Concept is based on the idea that activity of other threads will perform the TLB flush for the processes using emap as a side effect. To track that, global and per-CPU generation numbers are used. This idea was suggested by Andrew Doran; various improvements to it by me. Notes: - For now, zero-copy on pipe is not yet enabled. - TCP socket code would likely need more work. - Additional UVM loaning improvements are needed. Proposed on <tech-kern>, silence there. Quickly reviewed by <ad>.

- add new RLIMIT_AS (aka RLIMIT_VMEM) resource that limits the total
address space available to processes. this limit exists in most other
modern unix variants, and like most of them, our defaults are unlimited.
remove the old mmap / rlimit.datasize hack.
- adds the VMCMD_STACK flag to all the stack-creation vmcmd callers.
it is currently unused, but was added a few years ago.
- add a pair of new process size values to kinfo_proc2{}. one is the
total size of the process memory map, and the other is the total size
adjusted for unused stack space (since most processes have a lot of
this...)
- patch sh, and csh to notice RLIMIT_AS. (in some cases, the alias
RLIMIT_VMEM was already present and used if availble.)
- patch ps, top and systat to notice the new k_vm_vsize member of
kinfo_proc2{}.
- update irix, svr4, svr4_32, linux and osf1 emulations to support
this information. (freebsd could be done, but that it's best left
as part of the full-update of compat/freebsd.)
this addresses PR 7897. it also gives correct memory usage values,
which have never been entirely correct (since mmap), and have been
very incorrect since jemalloc() was enabled.
tested on i386 and sparc64, build tested on several other platforms.
thanks to many folks for feedback and testing but most espcially
chuq and yamt for critical suggestions that lead to this patch not
having a special ugliness i wasn't happy with anyway :-)

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.

Merge scheduler changes from the vmlocking branch. All discussed on tech-kern: - Invert priority space so that zero is the lowest priority. Rearrange number and type of priority levels into bands. Add new bands like 'kernel real time'. - Ignore the priority level passed to tsleep. Compute priority for sleep dynamically. - For SCHED_4BSD, make priority adjustment per-LWP, not per-process.

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.

Rearrange process exit path to avoid need to free resources from different
process context ('reaper').
From within the exiting process context:
* deactivate pmap and free vmspace while we can still block
* introduce MD cpu_lwp_free() - this cleans all MD-specific context (such
as FPU state), and is the last potentially blocking operation;
all of cpu_wait(), and most of cpu_exit(), is now folded into cpu_lwp_free()
* process is now immediatelly marked as zombie and made available for pickup
by parent; the remaining last lwp continues the exit as fully detached
* MI (rather than MD) code bumps uvmexp.swtch, cpu_exit() is now same
for both 'process' and 'lwp' exit
uvm_lwp_exit() is modified to never block; the u-area memory is now
always just linked to the list of available u-areas. Introduce (blocking)
uvm_uarea_drain(), which is called to release the excessive u-area memory;
this is called by parent within wait4(), or by pagedaemon on memory shortage.
uvm_uarea_free() is now private function within uvm_glue.c.
MD process/lwp exit code now always calls lwp_exit2() immediatelly after
switching away from the exiting lwp.
g/c now unneeded routines and variables, including the reaper kernel thread

Replace the traditional buffer memory management -- based on fixed per buffer virtual memory reservation and a private pool of memory pages -- by a scheme based on memory pools. This allows better utilization of memory because buffers can now be allocated with a granularity finer than the system's native page size (useful for filesystems with e.g. 1k or 2k fragment sizes). It also avoids fragmentation of virtual to physical memory mappings (due to the former fixed virtual address reservation) resulting in better utilization of MMU resources on some platforms. Finally, the scheme is more flexible by allowing run-time decisions on the amount of memory to be used for buffers. On the other hand, the effectiveness of the LRU queue for buffer recycling may be somewhat reduced compared to the traditional method since, due to the nature of the pool based memory allocation, the actual least recently used buffer may release its memory to a pool different from the one needed by a newly allocated buffer. However, this effect will kick in only if the system is under memory pressure.

eliminate uvm_useracc() in favor of checking the return value of copyin() or copyout(). uvm_useracc() tells us whether the mapping permissions allow access to the desired part of an address space, and many callers assume that this is the same as knowing whether an attempt to access that part of the address space will succeed. however, access to user space can fail for reasons other than insufficient permission, most notably that paging in any non-resident data can fail due to i/o errors. most of the callers of uvm_useracc() make the above incorrect assumption. the rest are all misguided optimizations, which optimize for the case where an operation will fail. we'd rather optimize for operations succeeding, in which case we should just attempt the access and handle failures due to insufficient permissions the same way we handle i/o errors. since there appear to be no good uses of uvm_useracc(), we'll just remove it.

simplify tests: The case where l_stat == LSONPROC and l_cpu == curcpu cannot happen because the pagedaemon is the LWP on curcpu and the pagedaemon is a kernel thread and the code is only used by the pagedaemon. See also updated patch in PR kern/23095, which I ment to checkin originally.

In uvm_lwp_fork(), check if PMAP_UAREA() is defined and if so, invoke it with the KVA of the newly-wired uarea. This is useful on some architectures (e.g. xscale) where the uarea mapping can be tweaked to use the mini-data cache instead of the main cache.

Rework the way in which the map is traversed when dumping core. Now we read-lock the map and call uvm_map_lookup_entry() instead of simply walking from the header to the next and to the next, etc. Dumping from sparsely populated amaps could cause faults that would result in amaps being split, which (in turn) resulted in the core dumping routines dumping some regions of memory twice. This makes the core file too large, the headers not match, gdb not work properly, and so on. Addresses PR 19260.

introduce a new UVM fault type, VM_FAULT_WIREMAX. this is different
from VM_FAULT_WIRE in that when the pages being wired are faulted in,
the simulated fault is at the maximum protection allowed for the mapping
instead of the current protection. use this in uvm_map_pageable{,_all}()
to fix the problem where writing via ptrace() to shared libraries that
are also mapped with wired mappings in another process causes a
diagnostic panic when the wired mapping is removed.
this is a really obscure problem so it deserves some more explanation.
ptrace() writing to another process ends up down in uvm_map_extract(),
which for MAP_PRIVATE mappings (such as shared libraries) will cause
the amap to be copied or created. then the amap is made shared
(ie. the AMAP_SHARED flag is set) between the kernel and the ptrace()d
process so that the kernel can modify pages in the amap and have the
ptrace()d process see the changes. then when the page being modified
is actually faulted on, the object pages (from the shared library vnode)
is copied to a new anon page and inserted into the shared amap.
to make all the processes sharing the amap actually see the new anon
page instead of the vnode page that was there before, we need to
invalidate all the pmap-level mappings of the vnode page in the pmaps
of the processes sharing the amap, but we don't have a good way of
doing this. the amap doesn't keep track of the vm_maps which map it.
so all we can do at this point is to remove all the mappings of the
page with pmap_page_protect(), but this has the unfortunate side-effect
of removing wired mappings as well. removing wired mappings with
pmap_page_protect() is a legitimate operation, it can happen when a file
with a wired mapping is truncated. so the pmap has no way of knowing
whether a request to remove a wired mapping is normal or when it's due to
this weird situation. so the pmap has to remove the weird mapping.
the process being ptrace()d goes away and life continues. then,
much later when we go to unwire or remove the wired vm_map mapping,
we discover that the pmap mapping has been removed when it should
still be there, and we panic.
so where did we go wrong? the problem is that we don't have any way
to update just the pmap mappings that need to be updated in this
scenario. we could invent a mechanism to do this, but that is much
more complicated than this change and it doesn't seem like the right
way to go in the long run either.
the real underlying problem here is that wired pmap mappings just
aren't a good concept. one of the original properties of the pmap
design was supposed to be that all the information in the pmap could
be thrown away at any time and the VM system could regenerate it all
through fault processing, but wired pmap mappings don't allow that.
a better design for UVM would not require wired pmap mappings,
and Chuck C. and I are talking about this, but it won't be done
anytime soon, so this change will do for now.
this change has the effect of causing MAP_PRIVATE mappings to be
copied to anonymous memory when they are mlock()d, so that uvm_fault()
doesn't need to copy these pages later when called from ptrace(), thus
avoiding the call to pmap_page_protect() and the panic that results
from this when the mlock()d region is unlocked or freed. note that
this change doesn't help the case where the wired mapping is MAP_SHARED.
discussed at great length with Chuck Cranor.

a whole bunch of changes to improve performance and robustness under load:
- remove special treatment of pager_map mappings in pmaps. this is
required now, since I've removed the globals that expose the address range.
pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
no longer any need to special-case it.
- eliminate struct uvm_vnode by moving its fields into struct vnode.
- rewrite the pageout path. the pager is now responsible for handling the
high-level requests instead of only getting control after a bunch of work
has already been done on its behalf. this will allow us to UBCify LFS,
which needs tighter control over its pages than other filesystems do.
writing a page to disk no longer requires making it read-only, which
allows us to write wired pages without causing all kinds of havoc.
- use a new PG_PAGEOUT flag to indicate that a page should be freed
on behalf of the pagedaemon when it's unlocked. this flag is very similar
to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
pageout fails due to eg. an indirect-block buffer being locked.
this allows us to remove the "version" field from struct vm_page,
and together with shrinking "loan_count" from 32 bits to 16,
struct vm_page is now 4 bytes smaller.
- no longer use PG_RELEASED for swap-backed pages. if the page is busy
because it's being paged out, we can't release the swap slot to be
reallocated until that write is complete, but unlike with vnodes we
don't keep a count of in-progress writes so there's no good way to
know when the write is done. instead, when we need to free a busy
swap-backed page, just sleep until we can get it busy ourselves.
- implement a fast-path for extending writes which allows us to avoid
zeroing new pages. this substantially reduces cpu usage.
- encapsulate the data used by the genfs code in a struct genfs_node,
which must be the first element of the filesystem-specific vnode data
for filesystems which use genfs_{get,put}pages().
- eliminate many of the UVM pagerops, since they aren't needed anymore
now that the pager "put" operation is a higher-level operation.
- enhance the genfs code to allow NFS to use the genfs_{get,put}pages
instead of a modified copy.
- clean up struct vnode by removing all the fields that used to be used by
the vfs_cluster.c code (which we don't use anymore with UBC).
- remove kmem_object and mb_object since they were useless.
instead of allocating pages to these objects, we now just allocate
pages with no object. such pages are mapped in the kernel until they
are freed, so we can use the mapping to find the page to free it.
this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment. Currently this is a no-op on most platforms, so they should see no difference. Reviewed by Jason.

Rather than starting init and creating kthreads by forking and then doing a cpu_set_kpc(), just pass the entry point and argument all the way down the fork path starting with fork1(). In order to avoid special-casing the normal fork in every cpu_fork(), MI code passes down child_return() and the child process pointer explicitly. This fixes a race condition on multiprocessor systems; a CPU could grab the newly created processes (which has been placed on a run queue) before cpu_set_kpc() would be performed.

Change the pmap_enter() API slightly; pmap_enter() now returns an error value (KERN_SUCCESS or KERN_RESOURCE_SHORTAGE) indicating if it succeeded or failed. Change the `wired' and `access_type' arguments to a single `flags' argument, which includes the access type, and flags: PMAP_WIRED the old `wired' boolean PMAP_CANFAIL pmap_enter() is allowed to fail If PMAP_CANFAIL is not specified, the pmap should behave as it always has in the face of a drastic resource shortage: fall over dead. Change the fault handler to deal with failure (which indicates resource shortage) by unlocking everything, waiting for the pagedaemon to free more memory, then retrying the fault.

Turn the proclist lock into a read/write spinlock. Update proclist locking calls to reflect this. Also, block statclock rather than softclock during in the proclist locking functions, to address a problem reported on current-users by Sean Doran.

Make uvm_vslock() return the error code from uvm_fault_wire(). All places which use uvm_vslock() should now test the return value. If it's not KERN_SUCCESS, wiring the pages failed, so the operation which is using uvm_vslock() should error out. XXX We currently just EFAULT a failed uvm_vslock(). We may want to do more about translating error codes in the future.

Allow the caller to specify a stack for the child process. If NULL, the child inherits the stack pointer from the parent (traditional behavior). Like the signal stack, the stack area is secified as a low address and a size; machine-dependent code accounts for stack direction. This is required for clone(2).

Add a new `access type' argument to pmap_enter(). This indicates what type of memory access a mapping was caused by. This is passed through from uvm_fault() and udv_fault(), and in most other cases is 0. The pmap module may use this to preset R/M information. On MMUs which require R/M emulation, the implementation may preset the bits and avoid taking another fault. On MMUs which keep R/M information in hardware, the implementation may preset its cached bits to speed up the next call to pmap_is_modified() or pmap_is_referenced().
