Add a new resource to limit the number of lwps per user, RLIMIT_NTHR. There is a global sysctl kern.maxlwp to control this, which is by default 2048. The first lwp of each process or kernel threads are not counted against the limit. To show the current resource usage per user, I added a new sysctl that dumps the uidinfo structure fields.

Measure kinfo_proc2::p_vm_vsize in pages, as it was always documented. This value seems to never have been used anywhere. This makes it consistent with it's cousin p_vm_msize (which is in pages as well and has several uses).

Refactor ps_strings access. Based on PK_32, write either the normal version or the 32bit compat layout in execve1. Introduce a new function copyin_psstrings for reading it back from userland and converting it to the native layout. Refactor procfs to share most of the code with the kern.proc_args sysctl handler. This material is based upon work partially supported by The NetBSD Foundation under a contract with Joerg Sonnenberger.

many changes for COMPAT_LINUX: - update the linux syscall table for each platform. - support new-style (NPTL) linux pthreads on all platforms. clone() with CLONE_THREAD uses 1 process with many LWPs instead of separate processes. - move the contents of sys__lwp_setprivate() into a new lwp_setprivate() and use that everywhere. - update linux_release[] and linux32_release[] to "2.6.18". - adjust placement of emul fork/exec/exit hooks as needed and adjust other emul code to match. - convert all struct emul definitions to use named initializers. - change the pid allocator to allow multiple pids to refer to the same proc. - remove a few fields from struct proc that are no longer needed. - disable the non-functional "vdso" code in linux32/amd64, glibc works fine without it. - fix a race in the futex code where we could miss a wakeup after a requeue operation. - redo futex locking to be a little more efficient.

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.

lwp0 seems like an lwp instead of a process, so move bits related to it from kern_proc.c to kern_lwp.c. This makes kern_proc "scheduling-clean" and more easily usable in environments with a non-integrated scheduler (like, to take a random example, rump).

Change RSS (resident set size) limit. Instead of setting it arbitrarily to the total free memory available to the system, use the smallest value between VM_MAXUSER_ADDRESS and total free memory (having a RSS limit bigger than VM_MAXUSER_ADDRESS has no real meaning). Fix a possible int overflow when ptoa(uvmexp.free) is bigger than 4GB with a 32 bits vaddr_t. This change is similar to the one made in rev 1.144 of uvm/uvm_glue.c.

Add the DTrace hooks to the kernel (KDTRACE_HOOKS config option). DTrace adds a pointer to the lwp and proc structures which it uses to manage its state. These are opaque from the kernel perspective to keep the kernel free of CDDL code. The state arenas are kmem_alloced and freed as proccesses and threads are created and destoyed. Also add a check for trap06 (privileged/illegal instruction) so that DTrace can check for D scripts that may have triggered the trap so it can clean up after them and resume normal operation. Ok with core@.

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>.

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.

Change the way p->p_limit (and hence p->p_rlimit) is locked. Should fix PR/36939 and make the rlimit code MP safe. Posted for comment to tech-kern (non received!) The p_limit field (for a process) is only be changed once (on the first write), and a reference to the old structure is kept (for code paths that have cached the pointer). Only p->p_limit is now locked by p->p_mutex, and since the referenced memory will not go away, is only needed if the pointer is to be changed. The contents of 'struct plimit' are all locked by pl_mutex, except that the code doesn't bother to acquire it for reads (which are basically atomic). Add FORK_SHARELIMIT that causes fork1() to share the limits between parent and child, use it for the IRIX_PR_SULIMIT. Fix borked test for both IRIX_PR_SUMASK and IRIX_PR_SDIR being set.

- Fix sleepq_block() to return EINTR if the LWP is cancelled. Pointed out by yamt@. - Introduce SOBJ_SLEEPQ_LIFO, and use for LWPs sleeping via _lwp_park. libpthread enqueues most waiters in LIFO order to try and wake LWPs that ran recently, since their working set is more likely to be in cache. Matching the order of insertion reduces the time spent searching queues in the kernel. - Do not boost the priority of LWPs sleeping in _lwp_park, just let them sleep at their user priority level. LWPs waiting for some I/O event in the kernel still wait with kernel priority and get woken more quickly. This needs more evaluation and is to be revisited, but the effect on a variety of benchmarks is positive. - When waking LWPs, do not send an IPI to remote CPUs or arrange for the current LWP to be preempted unless (a) the thread being awoken has kernel priority and has higher priority than the currently running thread or (b) the remote CPU is idle.

I think it existed to cache the numbers in kernel memory of a zombie when proc->p_stats was part of the 'u' area - so got freed earlier and wouldn't (easily) be accessible from a separate process. However since both the p_ru and p_stats fields are freed at the same time it is no longer needed. Ride the recent 4.99.19 version change.

introduce a function, proclist_foreach_call, to iterate all procs on a proclist and call the specified function for each of them. primarily to fix a procfs locking problem, but i think that it's useful for others as well. while i'm here, introduce PROCLIST_FOREACH macro, which is similar to LIST_FOREACH but skips marker entries which are used by proclist_foreach_call.

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

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.

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()

After some discussion with Mycroft, change splstatclock() to splclock(). The rule is that you don't get to call scheduler-related functions (e.g. wakeup()) above the clock interrupt. Going to statclock unnecessarily hoses e.g. serial interrupts on the SPARC.

Per my comment earlier in the file, we only need to go do splsoftclock() when write-locking the proclist; splstatclock() is a wee bit overkill.

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.

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.

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.

- Add a new proclist, deadproc, which holds dead-but-not-yet-zombie processes. - Create a new data structure, the proclist_desc, which contains a pointer to a proclist, and eventually, a pointer to the lock for that proclist. Declare a static array of proclist_descs, proclists[], consisting of allproc, deadproc, and zombproc.
