sys: Use membar_release/acquire around reference drop. This just goes through my recent reference count membar audit and changes membar_exit to membar_release and membar_enter to membar_acquire -- this should make everything cheaper on most CPUs without hurting correctness, because membar_acquire is generally cheaper than membar_enter.

sys: Membar audit around reference count releases. If two threads are using an object that is freed when the reference count goes to zero, we need to ensure that all memory operations related to the object happen before freeing the object. Using an atomic_dec_uint_nv(&refcnt) == 0 ensures that only one thread takes responsibility for freeing, but it's not enough to ensure that the other thread's memory operations happen before the freeing. Consider: Thread A Thread B obj->foo = 42; obj->baz = 73; mumble(&obj->bar); grumble(&obj->quux); /* membar_exit(); */ /* membar_exit(); */ atomic_dec -- not last atomic_dec -- last /* membar_enter(); */ KASSERT(invariant(obj->foo, obj->bar)); free_stuff(obj); The memory barriers ensure that obj->foo = 42; mumble(&obj->bar); in thread A happens before KASSERT(invariant(obj->foo, obj->bar)); free_stuff(obj); in thread B. Without them, this ordering is not guaranteed. So in general it is necessary to do membar_exit(); if (atomic_dec_uint_nv(&obj->refcnt) != 0) return; membar_enter(); to release a reference, for the `last one out hit the lights' style of reference counting. (This is in contrast to the style where one thread blocks new references and then waits under a lock for existing ones to drain with a condvar -- no membar needed thanks to mutex(9).) I searched for atomic_dec to find all these. Obviously we ought to have a better abstraction for this because there's so much copypasta. This is a stop-gap measure to fix actual bugs until we have that. It would be nice if an abstraction could gracefully handle the different styles of reference counting in use -- some years ago I drafted an API for this, but making it cover everything got a little out of hand (particularly with struct vnode::v_usecount) and I ended up setting it aside to work on psref/localcount instead for better scalability. I got bored of adding #ifdef __HAVE_ATOMIC_AS_MEMBAR everywhere, so I only put it on things that look performance-critical on 5sec review. We should really adopt membar_enter_preatomic/membar_exit_postatomic or something (except they are applicable only to atomic r/m/w, not to atomic_load/store_*, making the naming annoying) and get rid of all the ifdefs.

Add inline functions to manipulate the klists that link up knotes via kn_selnext: - klist_init() - klist_fini() - klist_insert() - klist_remove() These provide some API insulation from the implementation details of these lists (but not completely; see vn_knote_attach() and vn_knote_detach()). Currently just a wrapper around SLIST(9). This will make it significantly easier to switch kn_selnext linkage to a different kind of list.

On debugger attach to a prestarted process don't report SIGTRAP Introduce PSL_TRACEDCHILD that indicates tracking of birth of a process. A freshly forked process checks whether it is traced and if so, reports SIGTRAP + TRAP_CHLD event to a debugger as a result of tracking forks-like events. There is a time window when a debugger can attach to a newly created process and receive SIGTRAP + TRAP_CHLD instead of SIGSTOP. Fixes races in t_ptrace_wait* tests when a test hangs or misbehaves, especially the ones reported in tracer_sysctl_lookup_without_duplicates.

Load struct fdfile::ff_file with atomic_load_consume. Exceptions: when we're only testing whether it's there, not about to dereference it. Note: We do not use atomic_store_release to set it because the preceding mutex_exit should be enough. (That said, it's not clear the mutex_enter/exit is needed unless refcnt > 0 already, in which case maybe it would be a win to switch from the membar implied by mutex_enter to the membar implied by atomic_store_release -- which I would generally expect to be much cheaper. And a little clearer without a long comment.)

Fix a race condition when handling concurrent LWP signals and add a test Fix a race condition that caused PT_GET_SIGINFO to return incorrect information when multiple signals were delivered concurrently to different LWPs. Add a regression test that verifies that when 50 threads concurrently use pthread_kill() on themselves, the debugger receives all signals with correct information. The kernel uses separate signal queues for each LWP. However, the signal context used to implement PT_GET_SIGINFO is stored in 'struct proc' and therefore common to all LWPs in the process. Previously, this member was filled in kpsignal2(), i.e. when the signal was sent. This meant that if another LWP managed to send another signal concurrently, the data was overwritten before the process was stopped. As a result, PT_GET_SIGINFO did not report the correct LWP and signal (it could even report a different signal than wait()). This can be quite reliably reproduced with the number of 20 LWPs, however it can also occur with 10. This patch moves setting of signal context to issignal(), just before the process is actually stopped. The data is taken from per-LWP or per-process signal queue. The added test confirms that the debugger correctly receives all signals, and PT_GET_SIGINFO reports both correct LWP and signal number. Reviewed by kamil.

Add void * function pointer casts. There are different ways to "fix" those
warnings:
1. this one: add a void * cast (which I think is the least intrusive)
2. add pragmas to elide the warning
3. add intermediate inline conversion functions
4. change the called function prototypes, adding unused arguments and
converting some of the pointer arguments to void *.
5. make the functions varyadic (which defeats the purpose of checking)
6. pass command line flags to elide the warning
I did try 3 and 4 and I was not pleased with the result (sys_ptrace_common.c)
(3) added too much code and defines, and (4) made the regular use clumsy.

Fix one the the root causes of unreliability of the ptrace(2)ed threads In case of sigswitchin away in issignal() and continuing the execution on PT_CONTINUE (or equivalent call), there is a time window when another thread could cause the process state to be changed to PS_STOPPING. In the current logic, a thread would receive signal 0 (no-signal) and exit from issignal(), returning to userland and never finishing the process of stopping all LWPs. This causes hangs waitpid() waiting for SIGCHLD and the callout polling for the state of the process in an infinite loop. Instead of prompting for a returned signal from a debugger, repeat the issignal() loop, this will cause checking the PS_STOPPING flag again and sigswitching away in the scenario of stopping the process.

Refactor sigswitch() Make the function static as it is now local to kern_sig.c. Rename the 'relock' argument to 'proc_lock_held' as it is more verbose. This was suggested by mjg@freebsd. While there this flips the users between true<->false. Add additional KASSERT(9) calls here to validate whethe proc_lock is used accordingly.

This fixes missed in action signals. NetBSD truss can now report reliably all TRAP_SCE/SCX/etc events without reports of missed ones. his was one of the reasons why debuggee with multiple threads misbehaved under a debugger. This change is v.2 of the previously reverted commit for the same fix. This version contains recovery path that stopps triggering event SIGTRAP for a detached debugger.

Move TRAP_CHLD/TRAP_LWP ptrace information from struct proc to siginfo Storing struct ptrace_state information inside struct proc was vulnerable to synchronization bugs, as multiple events emitted in the same time were overwritting other ones. Cache the original parent process id in p_oppid. Reusing here p_opptr is in theory prone to slight race codition. Change the semantics of PT_GET_PROCESS_STATE, reutning EINVAL for calls prompting for the value in cases when there wasn't registered an appropriate event. Add an alternative approach to check the ptrace_state information, directly from the siginfo_t value returned from PT_GET_SIGINFO. The original PT_GET_PROCESS_STATE approach is kept for compat with older NetBSD and OpenBSD. New code is recommended to keep using PT_GET_PROCESS_STATE. Add a couple of compile-time asserts for assumptions in the code. No functional change intended in existing ptrace(2) software. All ATF ptrace(2) and ATF GDB tests pass. This change improves reliability of the threading ptrace(2) code.

Stop masking SIGSTOP in a vfork(2)ed child Keep the traditional BSD behavior masking SIGTSTP, SIGTTIN and SIGTTOU in a vfork(2)ed child before exec(3)/exit(3). This is useful in shells and prevents deadlocking, when a parent cannot unstop the sleeping child. Change the behavior for SIGSTOP. This signal is by design not maskable and this property shall be obeyed without exceptions. The STOP behavior is expected in the context of debuggers and useful in standalone programs. It is still possible to stop a vfork(2)ed child, however it requires proc.curproc.stopfork=1, but it is not a flexible solution. FreeBSD and OpenBSD keep masking SIGSTOP in a vfork(2)ed child. Linux does not mask stop signals in the same scenarios. This fixes ATF test: t_vfork:raise2. No known regressions reported in the existing ATF tests.

Correct handling of: vfork(2) + PT_TRACE_ME + raise(2) Follow the FreeBSD approach of not routing signals to the parent that is a became tracer after calling PT_TRACE_ME by the vfork(2)ed child (before exec(3)/exit(3)). Now if a child calls raise(3), the signal is processed directly to this child. Add new ATF ptrace(2) tests: - traceme_vfork_raise1 (SIGKILL) - traceme_vfork_raise2 (SIGSTOP) // temporarily disabled - traceme_vfork_raise3 (SIGABRT) - traceme_vfork_raise4 (SIGHUP) - traceme_vfork_raise5 (SIGCONT) The FreeBSD implementation introduces P_PPTRACE for this special case. Right know keep opencoding check of this case in the kernel. It might be refactored in future. The Linux kernel does not follow this approach and causes dead locking of the processes (parent and child). Defer handling SIGSTOP into future. This is an intermediate step towards correct handling of fork(2) and vfork(2) in the context of ptrace(2). All new tests pass. There are no regressions in existing ATF ptrace(2) tests.

This API covers other frontends to fork1(9) like posix_spawn(2) or clone(2), if they cause parent to wait for exec(2) or exit(2) of the child. Changes: - Add new argument to sigswitch() determining whether we need to acquire the proc_lock or whether it's already held. - Refactor fork1(9) for fork(2) and vfork(2)-like events. Call sigswitch() from fork(1) for forking or vforking parent, instead of emitting kpsignal(9). We need to emit the signal and suspend the parent, returning to user and relock proc_lock. - Add missing prototype for proc_stop_done() in kern_sig.c. - Make sigswitch a public function accessible from other kernel code including <sys/signalvar.h>. - Remove an entry about unimplemented PTRACE_VFORK in the ptrace(2) man page. - Permin PTRACE_VFORK in the ptrace(2) frontend for userland. - Remove expected failure for unimplemented PTRACE_VFORK tests in the ATF ptrace(2) test-suite. - Relax signal routing constraints under a debugger for a vfork(2)ed child. This intended to protect from signaling a parent of a vfork(2)ed child that called PT_TRACE_ME, but wrongly misrouted other signals in vfork(2) use-cases.

Remove the filesystem tracing feature This is a legacy interface from 4.4BSD, and it was introduced to overcome shortcomings of ptrace(2) at that time, which are no longer relevant (performance). Today /proc/#/ctl offers a narrow subset of ptrace(2) commands and is not applicable for modern applications use beyond simplistic tracing scenarios. This removal will simplify kernel internals. Users will still be able to use all the other /proc files. This change won't affect other procfs files neither Linux compat features within mount_procfs(8). /proc/#/ctl isn't available on Linux. Remove: - /proc/#/ctl from mount_procfs(8) - P_FSTRACE note from the documentation of ps(1) - /proc/#/ctl and filesystem tracing documentation from mount_procfs(8) - KAUTH_REQ_PROCESS_PROCFS_CTL documentation from kauth(9) - source code file miscfs/procfs/procfs_ctl.c - PFSctl and procfs_doctl() from sys/miscfs/procfs/procfs.h - KAUTH_REQ_PROCESS_PROCFS_CTL from sys/sys/kauth.h - PSL_FSTRACE (0x00010000) from sys/sys/proc.h - P_FSTRACE (0x00010000) from sys/sys/sysctl.h Reduce code complexity after removal of this functionality. Update TODO.ptrace accordingly: remove two entries about /proc tracing. Do not keep legacy notes as comments in the headers about removed PSL_FSTRACE / P_FSTRACE, as this interface had little number of users (close or equal to zero). Proposed on tech-kern@. All filesystem tracing utility users are encouraged to switch to ptrace(2). Sponsored by <The NetBSD Foundation>

Introduce new ptrace(2) interface: PT_SET_SIGINFO and PT_GET_SIGINFO
This interface is designed to read signal information emited to tracee and
fake this signal with new value.
This functionality is required to distinguish types of events that occured
in the tracee and intercepted by a debugger.
These accessors introduce a new structure type ptrace_siginfo:
/*
* Signal Information structure
*/
typedef struct ptrace_siginfo {
siginfo_t psi_siginfo; /* signal information structure */
lwpid_t psi_lwpid; /* destination LWP of the signal
* value 0 means the whole process
* (route signal to all LWPs) */
} ptrace_siginfo_t;
Include <sys/siginfo.h> in <sys/ptrace.h> in order to not break existing
software due to unknown symbol siginfo_t.
This interface has been proposed to the tech-kern@ mailing list.

Add another field to the SDT_PROBE_DEFINE macro, so our DTrace probes can named the same as those on other platforms. For example, proc:::exec-success, not proc:::exec_success. Implementation follows the same basic principle as FreeBSD's; add another field to the SDT_PROBE_DEFINE macro which is the name as exposed to userland.

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.

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.

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.

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.

For regular (non PIE) executables randomization is enabled for:

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__.

Change the process/lwp flags seen by userland via sysctl back to the P_*/L_* naming convention, and rename the in-kernel flags to avoid conflict. (P_ -> PK_, L_ -> LW_ ). Add back the (now unused) LSDEAD constant. Restores source compatibility with pre-newlock2 tools like ps or top. Reviewed by Andrew Doran.

-SUS says that a successful call to setcontext(2) does not return. This implies that _UC_CPU must be set in the context passed. 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. This is an error, except in the swapcontext() case where it can be easily caught in userland.

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.

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.

* 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.

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.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records. The general change has been to replace "struct proc *" with "struct lwp *" in various function prototypes, pass the lwp through and use l_proc to get the process pointer when needed.

When unblocking threads, do not call setrunnable() on the thread we will be returning because the code path that calls is will very likely call setrunnable() again on the returned thread, leading to a panic because the thread returned is already at LSRUN. This fixes a problem where netbsd would panic when using gdb (5.3) on a process with multiple lwp's like this: % gdb program (gdb) run ^C (gdb) quit

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(). Addresses PR kern/19990 by Martin Husemann, with suggestions from enami tsugutomo.

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.

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.

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...

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()

Introduce a new process state distinct from SRUN called SONPROC which indicates that the process is actually running on a processor. Test against SONPROC as appropriate rather than combinations of SRUN and curproc. Update all context switch code to properly set SONPROC when the process becomes the current process on the CPU.

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.

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.
