Changes to make EVFILT_PROC MP-safe: Because the locking protocol around processes is somewhat complex compared to other events that can be posted on kqueues, introduce new functions for posting NOTE_EXEC, NOTE_EXIT, and NOTE_FORK, rather than just using the generic knote() function. These functions KASSERT() their locking expectations, and deal with other complexities for each situation. knote_proc_fork(), in particiular, needs to handle NOTE_TRACK, which requires allocation of a new knote to attach to the child process. We don't want to be allocating memory while holding the parent's p_lock. Furthermore, we also have to attach the tracking note to the child process, which means we have to acquire the child's p_lock. So, to handle all this, we introduce some additional synchronization infrastructure around the 'knote' structure: - Add the ability to mark a knote as being in a state of flux. Knotes in this state are guaranteed not to be detached/deleted, thus allowing a code path drop other locks after putting a knote in this state. - Code paths that wish to detach/delete a knote must first check if the knote is in-flux. If so, they must wait for it to quiesce. Because multiple threads of execution may attempt this concurrently, a mechanism exists for a single LWP to claim the detach responsibility; all other threads simply wait for the knote to disappear before they can make further progress. - When kqueue_scan() encounters an in-flux knote, it simply treats the situation just like encountering another thread's queue marker -- wait for the flux to settle and continue on. (The "in-flux knote" idea was inspired by FreeBSD, but this works differently from their implementation, as the two kqueue implementations have diverged quite a bit.) knote_proc_fork() uses this infrastructure to implement NOTE_TRACK like so: - Attempt to put the original tracking knote into a state of flux; if this fails (because the note has a detach pending), we skip all processing (the original process has lost interest, and we simply won the race). - Once the note is in-flux, drop the kq and forking process's locks, and allocate 2 knotes: one to post the NOTE_CHILD event, and one to attach a new NOTE_TRACK to the child process. Notably, we do NOT go through kqueue_register() to do this, but rather do all of the work directly and KASSERT() our assumptions; this allows us to directly control our interaction with locks. All memory allocations here are performed with KM_NOSLEEP, in order to prevent holding the original knote in-flux indefinitely. - Because the NOTE_TRACK use case adds knotes to kqueues through a sort of back-door mechanism, we must serialize with the closing of the destination kqueue's file descriptor, so steal another bit from the kq_count field to notify other threads that a kqueue is on its way out to prevent new knotes from being enqueued while the close path detaches them. In addition to fixing EVFILT_PROC's reliance on KERNEL_LOCK, this also fixes a long-standing bug whereby a NOTE_CHILD event could be dropped if the child process exited before the interested process received the NOTE_CHILD event (the same knote would be used to deliver the NOTE_EXIT event, and would clobber the NOTE_CHILD's 'data' field). Add a bunch of comments to explain what's going on in various critical sections, and sprinkle additional KASSERT()s to validate assumptions in several more locations.

Refactor interval timers to make it possible to support types other than the BSD/POSIX per-process timers: - "struct ptimer" is split into "struct itimer" (common interval timer data) and "struct ptimer" (per-process timer data, which contains a "struct itimer"). - Introduce a new "struct itimer_ops" that supplies information about the specific kind of interval timer, including it's processing queue, the softint handle used to schedule processing, the function to call when the timer fires (which adds it to the queue), and an optional function to call when the CLOCK_REALTIME clock is changed by a call to clock_settime() or settimeofday(). - Rename some fuctions to clearly identify what they're operating on (ptimer vs itimer). - Use kmem(9) to allocate ptimer-related structures, rather than having dedicated pools for them. Welcome to NetBSD 9.99.77.

- Replace pid_table_lock with a lockless lookup covered by pserialize, with
the "writer" side being pid_table expansion. The basic idea is that when
doing an LWP lookup there is usually already a lock held (p->p_lock), or a
spin mutex that needs to be taken (l->l_mutex), and either can be used to
get the found LWP stable and confidently determine that all is correct.
- For user processes LSLARVAL implies the same thing as LSIDL ("not visible
by ID"), and lookup by ID in proc0 doesn't really happen. In-tree the new
state should be understood by top(1), the tty subsystem and so on, and
would attract the attention of 3rd party kernel grovellers in time, so
remove it and just rely on LSIDL.

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.

- proc_find() retains traditional semantics of requiring the canonical PID to look up a proc. Add a separate proc_find_lwpid() to look up a proc by the ID of any of its LWPs. - Add proc_find_lwp_acquire_proc(), which enables looking up the LWP *and* a proc given the ID of any LWP. Returns with the proc::p_lock held. - Rewrite lwp_find2() in terms of proc_find_lwp_acquire_proc(), and add allow the proc to be wildcarded, rather than just curproc or specific proc. - lwp_find2() now subsumes the original intent of lwp_getref_lwpid(), but in a much nicer way, so garbage-collect the remnants of that recently added mechanism.

Overhaul the way LWP IDs are allocated. Instead of each LWP having it's own LWP ID space, LWP IDs came from the same number space as PIDs. The lead LWP of a process gets the PID as its LID. If a multi-LWP process's lead LWP exits, the PID persists for the process. In addition to providing system-wide unique thread IDs, this also lets us eliminate the per-process LWP radix tree, and some associated locks. Remove the separate "global thread ID" map added previously; it is no longer needed to provide this functionality. Nudged in this direction by ad@ and chs@.

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.

Add support for PTRACE_POSIX_SPAWN to report posix_spawn(3) events posix_spawn(3) is a first class syscall in NetBSD, different to (V)FORK+EXEC as these operations are executed in one go. This differs to Linux and FreeBSD, where posix_spawn(3) is implemented with existing kernel primitives (clone(2), vfork(2), exec(3)) inside libc. Typically LLDB and GDB software is aware of FORK/VFORK events. As discussed with the LLDB community, instead of slicing the posix_spawn(3) operation into phases emulating (V)FORK+EXEC(+VFORK_DONE) and returning intermediate state to the debugger, that might have abnormal state, introduce new event type: PTRACE_POSIX_SPAWN. A debugger implementor can easily map it into existing fork+exec semantics or treat as a distinct event. There is no functional change for existing debuggers as there was no support for reporting posix_spawn(3) events on the kernel side.

Centralized shared part of child_return() into MI part Add a new function md_child_return() for MD specific bits only. New child_return() is now part of MI and central code that handles uniformly tracing code (KTR and ptrace(2)). Synchronize value passed to ktrsysret() among ports to SYS_fork. This is a traditional value and accessing p_lflag to check for PL_PPWAIT shall use locking against proc_lock. Returning SYS_fork vs SYS_vfork still isn't correct enough as there are more entry points to forking code. Instead of making it too good, just settle with plain SYS_fork for all ports.

PR/53998: Joel Bertrand: Limit the number of semaphores on a per-user basis not a per-process. We cannot really keep track on a per-process basis because a parent process can create the semaphore and a child can free it taking credit for it. There is also a similar issue about resource exhaustion if we limited the number of lwps per process as opposed to per user (which we don't).

Cause a process's user and system times to become non-decreasing. This alters the invented values (ie: statistically calculated) that are returned - for small values, the values are likely going to be different than they were, but that's largely nonsense anyway (except that the sum of utime & stime does equal cpu time consumed by the process). Once the values get large enough to be meaningful the difference made by this change will be in the noise, and irrelevant. This needs a couple of additions to struct proc, so we are now into 8.99.17

Make {s,g}et{db,fp,}regs work again for PK_32 processes
XXX: pullup-8
add disgusting magic to handle compat_netbsd32 as a module.
use process_*reg32 instead of struct *reg32.
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).

untangle the mess:
- factor out common code
- break each ptrace subcall to its own sub-function
.. more to come ...
- reduce ifdef ugliness by moving it up top.
- factor out PT_IO and make PT_{READ,WRITE}_{I,D} use it
- factor out PT_DUMPCORE
- factor out sendsig code
.. more to come ...
handle siginfo requests for ptrace32
ptrace: Partially undo PT_{READ,WRITE}_{I,D} and unbreak these commands
The refactored code did not work and was generating EFAULT.
Sponsored by <The NetBSD Foundation>
Merge the code back; the problem was that since we are reading/writing
to a kernel address for PT_{READ,WRITE}_{I,D} we need the kernel vmspace.
provide separate read and write functions to accomodate register functions
that need a size argument.
don't ignore error from copyout_piod
Use the proper process (the tracee) to get information about lwps and
registers and the tracer for vmspace.
Add new sysctl(3) entry: security.models.extensions.user_set_dbregs
Model this new sysctl(3) entry after "user_set_cpu_affinity" in the same
level of sysctl(3) switches.
Allow to read unconditionally Debug Registers (no change here). This is
convenient as even if a user of a debugger does not use hardware assisted
watchpoints/breakpoints, a debugger can still prompt these values to store
in an internal cache with context of registers. Reading them should have
no security concerns.
Add a paranoid MI switch that prohibits by default setting these registers
by a regular user (non-superuser). Make this switch disabled by default.
There are enough reserved bits out there to allow using them
unconditionally on hardened hosts.
Features shipped with Debug Registers are optional features in debuggers.
There is no reduction in elementary functionality.

Introduce PT_GETDBREGS and PT_SETDBREGS in ptrace(2) on i386 and amd64
This interface is modeled after FreeBSD API with the usage.
This replaced previous watchpoint API. The previous one was introduced
recently in NetBSD-current and remove its spurs without any
backward-compatibility.
Design choices for Debug Register accessors:
- exec() (TRAP_EXEC event) must remove debug registers from LWP
- debug registers are only per-LWP, not per-process globally
- debug registers must not be inherited after (v)forking a process
- debug registers must not be inherited after forking a thread
- a debugger is responsible to set global watchpoints/breakpoints with the
debug registers, to achieve this PTRACE_LWP_CREATE/PTRACE_LWP_EXIT event
monitoring function is designed to be used
- debug register traps must generate SIGTRAP with si_code TRAP_DBREG
- debugger is responsible to retrieve debug register state to distinguish
the exact debug register trap (DR6 is Status Register on x86)
- kernel must not remove debug register traps after triggering a trap event
a debugger is responsible to detach this trap with appropriate PT_SETDBREGS
call (DR7 is Control Register on x86)
- debug registers must not be exposed in mcontext
- userland must not be allowed to set a trap on the kernel
Implementation notes on i386 and amd64:
- the initial state of debug register is retrieved on boot and this value is
stored in a local copy (initdbregs), this value is used to initialize dbreg
context after PT_GETDBREGS
- struct dbregs is stored in pcb as a pointer and by default not initialized
- reserved registers (DR4-DR5, DR9-DR15) are ignored
Further ideas:
- restrict this interface with securelevel
Tested on real hardware i386 (Intel Pentium IV) and amd64 (Intel i7).
This commit enables 390 debug register ATF tests in kernel/arch/x86.
All tests are passing.
This commit does not cover netbsd32 compat code. Currently other interface
PT_GET_SIGINFO/PT_SET_SIGINFO is required in netbsd32 compat code in order to
validate reliably PT_GETDBREGS/PT_SETDBREGS.
This implementation does not cover FreeBSD specific defines in their
<x86/reg.h>: DBREG_DR7_LOCAL_ENABLE, DBREG_DR7_GLOBAL_ENABLE, DBREG_DR7_LEN_1
etc. These values tend to be reinvented by each tracer on its own. GNU
Debugger (GDB) works with NetBSD debug registers after adding this patch:
--- gdb/amd64bsd-nat.c.orig 2016-02-10 03:19:39.000000000 +0000

Introduce PTRACE_LWP_{CREATE,EXIT} in ptrace(2) and TRAP_LWP in siginfo(5)
Add interface in ptrace(2) to track thread (LWP) events:
- birth,
- termination.
The purpose of this thread is to keep track of the current thread state in
a tracee and apply e.g. per-thread designed hardware assisted watchpoints.
This interface reuses the EVENT_MASK and PROCESS_STATE interface, and
shares it with PTRACE_FORK, PTRACE_VFORK and PTRACE_VFORK_DONE.
Change the following structure:
typedef struct ptrace_state {
int pe_report_event;
pid_t pe_other_pid;
} ptrace_state_t;
to
typedef struct ptrace_state {
int pe_report_event;
union {
pid_t _pe_other_pid;
lwpid_t _pe_lwp;
} _option;
} ptrace_state_t;
#define pe_other_pid _option._pe_other_pid
#define pe_lwp _option._pe_lwp
This keeps size of ptrace_state_t unchanged as both pid_t and lwpid_t are
defined as int32_t-like integer. This change does not break existing
prebuilt software and has minimal effect on necessity for source-code
changes. In summary, this change should be binary compatible and shouldn't
break build of existing software.
Introduce new siginfo(5) type for LWP events under the SIGTRAP signal:
TRAP_LWP. This change will help debuggers to distinguish exact source of
SIGTRAP.
Add two basic t_ptrace_wait* tests:
lwp_create1:
Verify that 1 LWP creation is intercepted by ptrace(2) with
EVENT_MASK set to PTRACE_LWP_CREATE
lwp_exit1:
Verify that 1 LWP creation is intercepted by ptrace(2) with
EVENT_MASK set to PTRACE_LWP_EXIT
All tests are passing.
Surfing the previous kernel ABI bump to 7.99.59 for PTRACE_VFORK{,_DONE}.

Add support for PTRACE_VFORK_DONE and stub for PTRACE_VFORK in ptrace(2) PTRACE_VFORK is supposed to be used to track vfork(2)-like events, when parent gives birth to new process child and stops till it exits or calls exec(). Currently PTRACE_VFORK is a stub. PTRACE_VFORK_DONE is notification to notify a debugger that a parent has resumed after vfork(2)-like action. PTRACE_VFORK_DONE throws SIGTRAP with TRAP_CHLD.

We never exec(2) with a kernel vmspace, so do not test for that, but instead KASSERT() that we don't. When calculating the load address for the interpreter (e.g. ld.elf_so), we need to take into account wether the exec'd process will run with topdown memory or bottom up. We can not use the current vmspace's flags to test for that, as this happens too early. Luckily the execpack already knows what the new state will be later, so instead of testing the current vmspace, pass the info as additional argument to struct emul e_vm_default_addr. Fix all such functions and adopt all callers.

It was using the value of the cpu's %cr2 register but thats not valid: CR2 Contains a value called Page Fault Linear Address (PFLA).

When posting a signal from the debugger l->l_sigpendset is not set, so we use the process pending signal and add it back to the process pending set. 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. don't delete signal from the debugger. kern/kern_sleepq.c by christos: PR kern/40594: Antti Kantee: Don't call issignal() here to determine what errno to set for the interrupted syscall, because issignal() will consume the signal and it will not be delivered to the process afterwards. Instead call sigispending() (which now returns the first pending signal) and does not consume the signal. We need to process SA_STOP signals immediately, and not deliver them to the process. Instead of re-structuring the code to do that, call issignal() like before in that case.

Add a MAP_NOSYSCALLS flag to mmap. This flag prohibits executing of system calls from the mapped region. This can be used for emulation perposed or for extra security in the case of generated code. Its implemented by adding mapping-attributes to each uvm_map_entry. These can then be queried when needed. Currently the MAP_NOSYSCALLS is only implemented for x86 but other architectures are easy to adapt; see the sys/arch/x86/x86/syscall.c patch. Port maintainers are encouraged to add them for their processor ports too. When this feature is not yet implemented for an architecture the MAP_NOSYSCALLS is simply ignored with virtually no cpu cost..

Nuke all threads belonging to a process calling exec before allowing the exec handshake to return. In addition to being The Right Thing To Do, fixes some nasty conditions for CLOEXEC fd's (or at least does so in theory, I couldn't create any problems although I tried).

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.

Move sysctl routines from init_sysctl.c to kern_descrip.c (for descriptors) and kern_proc.c (for processes). This makes them usable in a rump kernel, in case somebody was wondering.

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.

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@.

Initial checkin of re-adding SA. Everything except kern_sa.c compiles in GENERIC for i386. This is still a work-in-progress, but this checkin covers most of the mechanical work (changing signalling to be able to accomidate SA's process-wide signalling and re-adding includes of sys/sa.h and savar.h). Subsequent changes will be much more interesting. Also, kern_sa.c has received partial cleanup. There's still more to do, though.

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.

Add PaX ASLR (Address Space Layout Randomization) [from elad and myself]
For regular (non PIE) executables randomization is enabled for:
1. The data segment
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__.

- Fix interactivity problems under high load. Beacuse soft interrupts
are being stacked on top of regular LWPs, more often than not aston()
was being called on a soft interrupt thread instead of a user thread,
meaning that preemption was not happening on EOI.
- Don't use bool in a couple of data structures. Sub-word writes are not
always atomic and may clobber other fields in the containing word.
- For SCHED_4BSD, make p_estcpu per thread (l_estcpu). Rework how the
dynamic priority level is calculated - it's much better behaved now.
- Kill the l_usrpri/l_priority split now that priorities are no longer
directly assigned by tsleep(). There are three fields describing LWP
priority:
l_priority: Dynamic priority calculated by the scheduler.
This does not change for kernel/realtime threads,
and always stays within the correct band. Eg for
timeshared LWPs it never moves out of the user
priority range. This is basically what l_usrpri
was before.
l_inheritedprio: Lent to the LWP due to priority inheritance
(turnstiles).
l_kpriority: A boolean value set true the first time an LWP
sleeps within the kernel. This indicates that the LWP
should get a priority boost as compensation for blocking.
lwp_eprio() now does the equivalent of sched_kpri() if
the flag is set. The flag is cleared in userret().
- Keep track of scheduling class (OTHER, FIFO, RR) in struct lwp, and use
this to make decisions in a few places where we previously tested for a
kernel thread.
- Partially fix itimers and usr/sys/intr time accounting in the presence
of software interrupts.
- Use kthread_create() to create idle LWPs. Move priority definitions
from the various modules into sys/param.h.
- newlwp -> lwp_create

Use a per-proc rwlock: rw_tryenter(RW_READER) to gain a reference, and rw_enter(RW_WRITER) by the process itself to drain out reference holders before major changes like exiting. - Fix numerous bugs and locking issues in procfs. - Mark procfs MPSAFE.

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.

proc_free: release proclist_lock earlier as suggested by Andrew Doran.
calling lwp_free with the lock held leads a deadlock.
1. CPU1: do_sys_wait -> lwp_free busy-waits for an LWP exiting on CPU2,
holding proclist_lock.
2. CPU2: the exiting LWP is interrupted by softclock.
3. CPU2: softclock -> sched_pstats tries to acquire proclist_lock.
it also busy-waits because the owning LWP is running.

- Fix a bug with _lwp_park() where if the computed wakeup time was under 1 microsecond into the future, the thread could enter an untimed sleep. - Change the signature of _lwp_park() to accept an lwpid_t and second hint pointer, but do so in a way that remains compatible with older pthread libraries. This can be used to wake another thread before the calling thread goes asleep, saving at least one syscall + involuntary context switch. This turns out to be a fairly large win on the condvar benchmarks that I have tried. - Mark some more syscalls MP safe.

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.

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.

fix a long-standing scheduler problem that p_estcpu is doubled for each fork-wait cycles. - updatepri: factor out the code to decay estcpu so that it can be used by scheduler_wait_hook. - scheduler_fork_hook: record how much estcpu is inherited from the parent process. - scheduler_wait_hook: don't add back inherited estcpu to the parent.

make scheduler work better when a system has many runnable processes by making p_estcpu fixpt_t. PR/31542. 1. schedcpu() decreases p_estcpu of all processes every seconds, by at least 1 regardless of load average. 2. schedclock() increases p_estcpu of curproc by 1, at about 16 hz. in the consequence, if a system has >16 processes with runnable lwps, their p_estcpu are not likely increased. by making p_estcpu fixpt_t, we can decay it more slowly when loadavg is high. (ie. solve #1.) i left kinfo_proc2::p_estcpu (ie. ps -O cpu) scaled because i have no idea about its absolute value's usage other than debugging, for which raw values are more valuable.

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

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.

Introduce lwp_emuldata and the associated hooks. No hook is provided for the exec case, as the emulation already has the ability to intercept that with the e_proc_exec hook. It is the responsability of the emulation to take appropriaye action about lwp_emuldata in e_proc_exec. Patch reviewed by Christos.

Dynamic sysctl. Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(), vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.

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)

add support for non-executable mappings (where the hardware allows this) and make the stack and heap non-executable by default. the changes fall into two basic catagories: - pmap and trap-handler changes. these are all MD: = alpha: we already track per-page execute permission with the (software) PG_EXEC bit, so just have the trap handler pay attention to it. = i386: use a new GDT segment for %cs for processes that have no executable mappings above a certain threshold (currently the bottom of the stack). track per-page execute permission with the last unused PTE bit. = powerpc/ibm4xx: just use the hardware exec bit. = powerpc/oea: we already track per-page exec bits, but the hardware only implements non-exec mappings at the segment level. so track the number of executable mappings in each segment and turn on the no-exec segment bit iff the count is 0. adjust the trap handler to deal. = sparc (sun4m): fix our use of the hardware protection bits. fix the trap handler to recognize text faults. = sparc64: split the existing unified TSB into data and instruction TSBs, and only load TTEs into the appropriate TSB(s) for the permissions. fix the trap handler to check for execute permission. = not yet implemented: amd64, hppa, sh5 - changes in all the emulations that put a signal trampoline on the stack. instead, we now put the trampoline into a uvm_aobj and map that into the process separately. originally from openbsd, adapted for netbsd by me.

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.

- Introduce a e_fault field in struct proc to provide emulation specific memory fault handler. IRIX uses irix_vm_fault, and all other emulation use NULL, which means to use uvm_fault. - While we are there, explicitely set to NULL the uninitialized fields in struct emul: e_fault and e_sysctl on most ports - e_fault is used by the trap handler, for now only on mips. In order to avoid intrusive modifications in UVM, the function pointed by e_fault does not has exactly the same protoype as uvm_fault: int uvm_fault __P((struct vm_map *, vaddr_t, vm_fault_t, vm_prot_t)); int e_fault __P((struct proc *, vaddr_t, vm_fault_t, vm_prot_t)); - In IRIX share groups, all the VM space is shared, except one page. This bounds us to have different VM spaces and synchronize modifications to the VM space accross share group members. We need an IRIX specific hook to the page fault handler in order to propagate VM space modifications caused by page faults.

Pull up revision 1.142 (requested by jdolocek in ticket #557): Make sure that the pointer to old parent process for ptraced children gets reset properly when the old parent exits before the child. 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.

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.

Note this implementation does not yet implement priority inheritence, nor does it currently differentiate between reader and writer queues (though they are provided for in the API).

Added two flags to emulation packages: EMUL_BSD_ASYNCIO_PIPE notes that the emulated binaries expect the original BSD pipe behavior for asynchronous I/O, which is to fire SIGIO on read() and write(). OSes without this flag do not expect any SIGIO to be fired on read() and write() for pipes, even when async I/O was requested. As far as we know, the OSes that need EMUL_BSD_ASYNCIO_PIPE are NetBSD, OSF/1 and Darwin. EMUL_NO_SIGIO_ON_READ notes that the emulated binaries that requested asynchrnous I/O expect the reader process to be notified by a SIGIO, but not the writer process. OSes without this flag expect the reader and the writer to be notified when some data has arrived or when some data have been read. As far as we know, the OSes that need EMUL_NO_SIGIO_ON_READ are Linux and SunOS.

per emulation and contains pointer to respective probe function
- interp is allocated via MALLOC() rather than on stack
- elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is

In vfs_shutdown() use suspendsched() suspend scheduling, and use tsleep() instead of DELAY to give kernel threads a chance to run (needed to flush buffers to a RAID disk). Also, keep trying flushing buffers when the number of dirty buffers decreases (20 rounds may not be enouth for a very large buffer cache).

Implement suspendsched() by putting all sleeping and runnable processes in SSTOP state, execpt P_SYSTEM and curproc processes. We have to way to find the original state of the process so we can't restart scheduling, so this can only be used at shutdown time. XXX suspendsched() should also deal with processes running on other CPUs. I don't know how to do that, and as long as we have a kernel big lock, this shouldn't be a problem.

Add the sched_suspend/sched_resume functions, as discussed on tech-kern, with the following modifications to the initial patch: - rename SHOLD and P_HOST to SSUSPEND and P_SUSPEND to avoid confusion with PHOLD() - don't deal with SSUSPEND/P_SUSPEND in fork1(), if we come here while scheduler is suspended we're forking proc0, which can't have P_SUSPEND set. sched_suspend() suspends the scheduling of users process, by removing all processes from the run queues and changing their state from SRUN to SSUSPEND. Also mark all user process but curproc P_SUSPEND. When a process has to be put in SRUN and is marked P_SUSPEND, it's placed in the SSUSPEND state instead. sched_resume() places all SSUSPEND processes back in SRUN, clear the P_SUSPEND flag.

Track which process a CPU is running/has last run on by adding a p_cpu member to struct proc. Use this in certain places when accessing scheduler state, etc. For the single-processor case, just initialize p_cpu in fork1() to avoid having to set it in the low-level context switch code on platforms which will never have multiprocessing. While I'm here, comment a few places where there are known issues for the SMP implementation.

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.

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()

First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state: - Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future. - Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU). - Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate. - All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made. Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

The sysctl also takes the size of each element, so that if "struct kinfo_proc2" grows over time old binaries will still be able to request a fixed size amount of data. + KERN_PROC_ARGS - return the argv or envv for a particular process id. envv will only be returned if the process has the same user id as the requestor or if the requestor is root. + KERN_FSCALE - return the current kernel fixpt scale factor. + KERN_CCPU - return the scheduler exponential decay value. + KERN_CP_TIME - return cpu time state counters.

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.

New callout mechanism with two major improvements over the old timeout()/untimeout() API: - Clients supply callout handle storage, thus eliminating problems of resource allocation. - Insertion and removal of callouts is constant time, important as this facility is used quite a lot in the kernel. The old timeout()/untimeout() API has been removed from the kernel.

Add some very simple code to auto-size the kmem_map. We take the amount of physical memory, divide it by 4, and then allow machine dependent code to place upper and lower bounds on the size. Export the computed value to userspace via the new "vm.nkmempages" sysctl. NKMEMCLUSTERS is now deprecated and will generate an error if you attempt to use it. The new option, should you choose to use it, is called NKMEMPAGES, and two new options NKMEMPAGES_MIN and NKMEMPAGES_MAX allow the user to configure the bounds in the kernel config file.

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).

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.

Significantly restructure the way signal state for a process is stored. Rather than using bitmasks to redundantly store the information kept in the process's sigacts (because the sigacts was kept in the u-area), hang sigacts directly off the process, and access it directly. Simplify signal setup code tremendously by storing information in the sigacts as an array of struct sigactions, rather than in a different format, since userspace uses sigactions. Make sigacts sharable by adding reference counting.

Fix an inconsistency that came in with Lite: setrq() was renamed to setrunqueue(), but remrq() was never renamed. Rename remrq() to remrunqueue(). Also, move remrunqueue() prototype from vm/vm_extern.h to sys/proc.h, so that it's in the same place as the setrunqueue() prototype and other related prototypes.
