* Committed the wrong version (an earlier try) of the KERN_FILE2 vsguenther2012-06-021-2/+4
| | | | rthreads fix. Update to the correct one.
* Eliminate the f_usecount ref count in struct file; instead of sleepingguenther2012-05-011-2/+2
| | | | | | | | | at the top of closef() until all in-progress calls finish, just do the advisory locking bits required of close() by POSIX and let whichever thread has the last reference do the call to the file's fo_close() method and the final cleanup. lots of discussion with deraadt@ and others; worked out with and ok krw@
* Fix kvm_deadfile2_byid()'s handling of kernel vs user addresses forguenther2012-04-201-14/+43
| | | | | | | | fd_ofiles and fd_ofileflags, reading in the separate allocation when necessary. Lets fstat -p and fstat -u work on kernel crash dumps again. ok millert@
* Make it optional for kvm_getprocs() (and related sysctl) to returnpirofti2012-04-171-1/+9
| | | | | | | | | | | | thread information. Add a KERN_PROC_SHOW_THREADS flag that has to be set in order to get the thread info and make it off by default. This creates backwards compatibility for applications that relied on a given size/number of items to be returned. Modify ps(1) and top(1) accordingly. Okay guenther@.

* Add per thread accounting, mainly for usage & friends.pirofti2012-04-122-5/+40
| | | | | | | | | | | | | | This expands the already bloated FILL_KPROC macro to take an extra parameter that indicates if the callee is a thread or a process. The userland bits are adjusted accordingly and ps(1) and top(1) now display per thread usage times when -H is used. Also pkill(1) had to be adjusted so that duplicates don't pop up. libkvm does basically the same thing as the kernel bits. Okay guenther@.
* libkvm: minor bumpariane2012-04-111-1/+1
| | | | Due to the struct size of vm_map_entry having grown by sizeof(vsize_t).
* The kinfo_file2 structure's f_wbytes member was being filled with theguenther2012-03-281-2/+2
| | | | | | read byte count instead of the written byte count. pointed out by paulm at tetrardus.net, ok dcoppa@

| | | | | | | of per-rthread. Handling of per-thread tick and runtime counters inspired by how FreeBSD does it. ok kettenis@
* pull in more .h (spotted since struct vnode was not in scope)deraadt2012-03-161-1/+12

* 0 is a valid uid for files sysctl, don't skip it. reminded by guenthertedu2012-03-131-2/+2

* Major bump, since struct vm_map and vm_map_entry changed size and layout.ariane2012-03-091-1/+1

* Userspace counterpart of new vmmap.ariane2012-03-091-13/+14
| | | | Allows memory walks to function.
* Add rtable id and thread id to struct kinfo_proc (and fix process id)guenther2012-01-076-65/+53
| | | | | | | | | | | and add an 'rtableid' keyword to ps. Add rtable id, thread id, and socket splice info to struct kinfo_file2 and make fstat display socket splice information. Remove old KVM_PROC2 and kinfo_proc2 interfaces; bump libkvm major Socket splice info and corrections from bluhm@ "Lovely" deraadt@
* The ktrace vnode has moved to struct process and changed name.guenther2011-12-141-3/+3
| | | | Missed commit pointed out by mikeb@

* Recommit the reverted sigacts change now that the NFS use-after-freeguenther2011-07-051-2/+14
| | | | | | | | problem has been tracked down. This fixes the sharing of the signal handling state: shared bits go in sigacts, per-rthread bits goes in struct proc. ok deraadt@
* move the specfs code to a place people can see it; ok guenther thib krwderaadt2011-07-042-6/+4

* Userland counterpart of the vmmap backout; cranks major version of libkvm.ariane2011-06-062-15/+14
|
* Reimplement uvm/uvm_map.ariane2011-05-241-13/+14
| | | | | | | | | | | | | vmmap is designed to perform address space randomized allocations, without letting fragmentation of the address space go through the roof. Some highlights: - kernel address space randomization - proper implementation of guardpages - roughly 10% system time reduction during kernel build Tested by alot of people on tech@ and developers. Theo's machines are still happy.
* Revert the sigacts diff: NFS can apparently retain pointers to processesguenther2011-04-181-14/+2
| | | | | | until they're zombies and then send them signals (for intr mounts). Until that is untangled, the sigacts change is unsafe. sthen@ was the victim for this one
* p_sigacts is NULL for zombies, so FILL_KPROC() and kvm_proclist() haveguenther2011-04-151-7/+12
| | | | | | to handle that with the sigacts change. problem observed and diagnosed by claudio@ and kettenis@
* Correct the sharing of the signal handling state: stuff that shouldguenther2011-04-151-2/+9
| | | | | | | | | | | | be shared (p_sigignore, p_sigcatch, P_NOCLDSTOP, P_NOCLDWAIT) moves to struct sigacts, wihle stuff that should be per rthread (ps_oldmask, SAS_OLDMASK, ps_sigstk) moves to struct proc. Treat the coredumping state bits (ps_sig, ps_code, ps_type, ps_sigval) as per-rthread until our locking around coredumping is better. Oh, and remove the old SunOS-compat ps_usertramp member.

* Replace the old, broken KERN_PROC ABI and its matching functionsguenther2011-03-126-370/+66
| | | | | | | | | in libkvm with the stable-ABI versions that are currently named KERN_PROC2, kvm_get{proc,argv,envv}2(). The latter names and symbols will continue to be supported for a few releases. Committing now that they ports people have had a couple releases to update pkgs that usd the old functions

* Correct the links between threads, processes, pgrps, and sessions,guenther2010-07-262-20/+34
| | | | | | | | | so that the process-level stuff is to/from struct process and not struct proc. This fixes a bunch of problem cases in rthreads. Based on earlier work by blambert and myself, but mostly written at c2k10. Tested by many: deraadt, sthen, krw, ray, and in snapshots
* Move some macros in <msdosfs/denode.h> to outside the #ifdef _KERNELguenther2010-07-171-3/+1
| | | | | | so that libkvm doesn't need to define that, thereby avoiding some warnings. ok miod@
* Fail instead of lying if a process asks sysctl()'s KERN_PROC2 orguenther2010-06-292-2/+13
| | | | | | | KERN_FILE2 (or their libkvm wrappers) for more information than the running implementation knows how to provide. ok millert@ deraadt@
* Use MACHINE_CPU instead of MACHINE_ARCH to pick the correct machine dependentmiod2010-02-031-2/+7
| | | | | | | files or directories when applicable. The inspiration and name of MACHINE_CPU come from NetBSD, although the way to provide it to Makefiles is completely different. ok kettenis@
* the comment is right, this can indeed go away.jasper2010-01-121-2/+1
| | | | | | it's unused inside libkvm, and nothing else is allowed to use it. ok guenther@ "sure" deraadt@
* Reimplement kvm_getproc2()'s support for reading crash dumps andguenther2010-01-104-204/+383
| | | | | | | | | | | | | | /dev/mem to be direct instead of going through kvm_getprocs(), as that function is going to get more an more broken as we move stuff from struct proc to struct process for rthreads. To minimize the code copying, put the common logic of filling in a kinfo_proc2 structure into a macro FILL_KPROC2() in <sys/sysctl.h> for use from both the kernel and user-space. This also hides the KERN_PROC #define behind "#if defined(_KERNEL)||defined(_LIBKVM)", as it's deprecated. Positive feedback from millert and blambert; so committing to unblock further rthreads work.

* Allow mips ports to override VM_{MIN,MAX}_KERNEL_ADDRESS, and provide themiod2009-11-221-3/+15
| | | | | | | address as a kernel variable for use by libkvm. On sgi IP27 and IP30 kernels, use XKSEG instead of CKSSEG; this will allow kernel KVM size to grow in the future if necessary.
