exit_lwps, lwp_wait: fix a race condition by re-trying if p_lock was dropped in a case of process exit. Necessary to re-flag all LWPs for exit, as their state might have changed or new LWPs spawned. Should fix PR/46168 and PR/46402.

Use separate names for the multitudinous uses of `q' in exit1. Now I can follow which process is which in this routine. If I jiggle the whitespace so line numbers don't change, there is no change in the output of `objdump -d kern_exit.o' for amd64. ok abp

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

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.

Adjust the sleeps in lwpcache and lwpublk. Make them uninterruptable for now. This will prevent signals from waking them. Adjust exit_lwps() to explicitly add LW_SINTR to all of them, so that the process exit code can wake them up. This is needed as threads in both of these wait channels die once they are woken. So they aren't interruptable in the typical sense. I am now able to suspend & resume firefox successfully now.

Add MI code to support in-kernel preemption. Preemption is deferred by one of the following: - Holding kernel_lock (indicating that the code is not MT safe). - Bracketing critical sections with kpreempt_disable/kpreempt_enable. - Holding the interrupt priority level above IPL_NONE. Statistics on kernel preemption are reported via event counters, and where preemption is deferred for some reason, it's also reported via lockstat. The LWP priority at which preemption is triggered is tuneable via sysctl.

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.

A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).

- 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.

Remove proc->p_ru and the 'rusage' pool. 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.

Improvements to lwp_wait1(), for PR kern/35932: - Better detect simple cycles of threads calling _lwp_wait and return EDEADLK. Does not handle deeper cycles like t1 -> t2 -> t3 -> t1. - If there are multiple threads in _lwp_wait, then make sure that targeted waits take precedence over waits for any LWP to exit. - When checking for deadlock, also count the number of zombies currently in the process as potentially reapable. Whenever a zombie is murdered, kick all waiters to make them check again for deadlock. - Add more comments. Also, while here: - LOCK_ASSERT -> KASSERT in some places - lwp_free: change boolean arguments to type 'bool'. - proc_free: let lwp_free spin waiting for the last LWP to exit, there's no reason to do it here.

Don't free specificdata in lwp_exit2(); it's not safe to block there. Instead, free an LWP's specificdata from lwp_exit() (if it is not the last LWP) or exit1() (if it is the last LWP). For consistency, free the proc's specificdata from exit1() as well. Add lwp_finispecific() and proc_finispecific() functions to make this more convenient.

1) Complete Linux exit_group() emulation Members of the thread group must die without reporting to the parent and without going to zombie stage. We do that by reparenting to init before catching a SIGKILL. The parent will not see the child death. The thread group leader must report the exit status, even if it exits because of another thread calling exit_group(). We do that by storing the exit status in struct linux_emuldata_shared, and the exit hook has the duty of setting struct proc's p_xstat for the thread group leader. 2) For exit/fork/exec hooks, move the NPTL specific code to separate functions that are shared between COMPAT_LINUX and COMPAT_LINUX32 3) Fix LINUX_CLONE_PARENT_SETTID semantics

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.

once exit1() releases big kernel lock, the struct proc can be freed and re-used by another cpu immediately. in that case, lwp_exit2() will access freed memory. to fix this: - remove curlwp from p_lwps in exit1() rather than letting lwp_exit2() do so. - add assertions to ensure freed proc has no lwps. kern/24329 from me and kern/24574 from Havard Eidnes.

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

kernel part of no-syscall upcall stack return: libpthread registers an offset between ss_sp and struct sa_stackinfo_t (located in struct __pthread_st) when calling sa_register. The kernel increments the sast_gen counter in struct sastack when an upcall stack is used. libpthread increments the sasi_stackgen counter in struct sa_stackinfo_t when an upcall stack is freed. The kernel compares the two counters to decide if a stack is free or in use. - add struct sa_stackinfo_t with sasi_stackgen to count stack use in userland - add sast_gen to struct sastack to count stack use in kernel - add SA_FLAG_STACKINFO to enable the stackinfo_offset argument in the sa_register syscall - add sa_stackinfo_offset to struct sadata for offset between ss_sp and struct sa_stackinfo_t - add ssize_t stackinfo_offset argument to sa_register, initialize struct sadata's sa_stackinfo_offset from it if SA_FLAG_STACKINFO is set - add sa_getstack, sa_getstack0, sa_stackused and sa_setstackfree functions to find/use/free upcall stacks and use these where appropriate - don't record stack for upcall in sa_upcall0 - pass sau to sa_switchcall instead of l2 (l2 = curlwp in sa_switchcall) - add sa_vp_blocker to struct sadata to pass recently blocked lwp to sa_switchcall - delay finding a stack for blocked upcalls to sa_switchcall - add sa_stacknext to struct sadata pointing to next most likely free upcall stack; also g/c sa_stackslist in struct sadata and sast_list in struct sastack - add L_SA_WOKEN flag: LWP is on sa_woken queue - add L_SA_RECYCLE flag: LWP should be recycled in sa_setwoken - replace l_upcallstack with L_SA_WOKEN/L_SA_RECYCLE/L_SA_BLOCKING flags - g/c now unused sast_blocker in struct sastack - make sa_switchcall, sa_upcall0 and sa_upcall_getstate static in kern_sa.c - call sa_upcall_userret only once in userret - split sa_makeupcalls out of sa_upcall_userret and use to process the sa_upcalls queue - on process exit: mark LWPs sleeping in saunblock interruptible; also there are no LWPs sleeping on l->l_upcallstack anymore; also clear sa_wokenq_head to prevent unblocked upcalls additional changes: - cleanup timerupcall sa_vp == curlwp check - add check in sa_yield if we didn't block on our way here and we wouldn't any longer be the LWP on the VP - invalidate sa_vp_ofaultaddr after resolving pagefault

exit1(): make sure that, if orphaned child is being traced, it's reparented back to original parent before it's killed. This makes the original parent aware that the child has exited if the debugger failed to wait() on the debugged zombie before exiting. Since we clear tracing flags before killing the child, the reparenting logic in wait4() wouldn't be triggered, so it's necessary to do it here.

A flag is set in old parent process when the child is reparented in ptrace(2). If it's set when process is exiting, all running processes have their 'old parent process' pointer checked and reset if appropriate. Also change to use 'struct proc *' pointer directly, rather than pid_t. This fixes security/14444 by David Sainty. Reviewed by Christos Zoulas.

Don't uvm_deallocate() the address space in exit1(). The address space is already torn down in uvmspace_free() when the vmspace refrence count reaches 0. Move the shmexit() call into uvmspace_free(). Note that there is a beneficial side-effect of deferring the unmap to uvmspace_free() -- on systems where TLB invalidations are particularly expensive, the unmapping of the address space won't have to cause TLB invalidations; uvmspace_free() is going to be run in a context other than the exiting process's, so the "pmap is active" test will evaluate to FALSE in the pmap module.

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.

A few things to make the Linux clone(2) emulation work a bit better: - When the exit signal is specified to be 0, don't just assume they meant SIGCHLD. In the Linux world, this appears to mean "don't deliver an exit signal at all". - Simplify P_EXITSIG(); don't check against initproc here, just change the exit signal to SIGCHLD if reparenting to initproc. A very simple clone(2) test program now works, and the MpegTV package starts, but doesn't run properly yet (I believe there is a separate bug which keeps it from working properly).

Fix the recently infamous "sucky performance" problem by charging wait(2)'ing parents for children's p_estcpu. I think this problem has always been there. It's particularly noticable with X because the server builds up non-trivial CPU, and hence, non-trivial p_estcpu scheduler penalty. The repeatedly forked children were always starting from scratch and receiving a scheduler preference.

Substantial signal handling changes: * Increase the size of sigset_t to accomodate 128 signals -- adding new versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and sys_sigsuspend() to handle the changed arguments. * Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(), sys_sigpending() and sys_sigsuspend() into separate functions, and call them from all the emulations rather than hard-coding everything. (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.

Delay turning off P_TRACED until the process is actually waited on. It can't have any signals delivered while exiting, so this should be okay. Change the test for a traced process in wait4() to exclude a process that was started by the debugger; in this case, only one SIGCHLD should be delivered.

Reinstate P_FSTRACE, with different semantics: * Never send a SIGCHLD to the parent if P_FSTRACE is set. * Do not permit mixing ptrace(2) and procfs; only permit using the one that was attached.

Mike Karels' solution to Andrew Herbert <andrew@werple.apana.org.au>'s kern_exit race condition problem. this is a hack: don't vrele() or vgoneall() if we don't have the vnode any more. no vgoneall() is necessary, because if the refcnt is zero, there's nobody to take it away from! a possible "real" long term solution would be to change the extra ref into a bit in the vnode's flags, and DTRT in the places where the last ref is killed. That has some problems, too.

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.
