2014-07-08decouple struct uvmexp into a new file, so that uvm_extern.h and sysctl.hTheo de Raadt
don't need to be married. ok guenther miod beck jsing kettenis
2014-07-04Track whether a process is a zombie or not yet fully built via flagsPhilip Guenther
PS_{ZOMBIE,EMBRYO} on the process instead of peeking into the process's thread data. This eliminates the need for the thread-level SDEAD state. Change kvm_getprocs() (both the sysctl() and kvm backends) to report the "most active" scheduler state for the process's threads. tweaks kettenis@ feedback and ok matthew@
2014-06-04In fusefs_unmount() we need to send the FBT_DESTROY fusebuf only ifSylvestre Gallon
vflush(9) succeed. Problem reported by Helg Bredow. OK sthen@
2014-05-20Add -o max_read=XXX support in fuse. This is needed by usmb to have aSylvestre Gallon
working read() and write(). ok tedu@
2014-05-19Add some consistency in fuse error handling. We need to return ENXIOSylvestre Gallon
when the fuse communication channel is broken and ENOSYS when the libfuse callback does not exist. Reported by Helg Bredow, thanks! ok tedu@
2014-05-06Include <sys/vmmeter.h> directly instead of relying on it beingMartin Pieuchot
pulled by <uvm/uvm_extern.h> and turn uvm_total() into a private function. The preferred way to get memory stats is through the VM_UVMEXP sysctl(3) since VM_METER is just a wrapper on top of it. In the kernel, use `uvmexp' directly instead of uvm_total(). This change does not remove <sys/vmmeter.h> from <uvm/uvm_extern.h> to give some more time to port maintainers to fix their ports. ok guenther@ as part of a larger diff.
2014-03-18Do not rely on the fact that sys/vnode.h includes all the worldMartin Pieuchot
through uvm/uvm.h and add proper includes for function definitions. ok syl@

2014-01-20Threads can't be zombies, only processes, so change zombproc to zombprocess,Philip Guenther
make it a list of processes, and change P_NOZOMBIE and P_STOPPED from thread flags to process flags. Add allprocess list for the code that just wants to see processes. ok tedu@
2014-01-20Do not complain if release is not implemented in fuse client.Sylvestre Gallon
ok millert@.
2014-01-20Move p_textvp from struct proc to struct process so that the exit codePhilip Guenther
can be further simplified. ok kettenis@

OK tedu@ "it looks good to me" from guenther@

Input from millert@. Ok millert@, tedu@.
2013-12-10Unset fuse_mnt in fusefs_unmount after vflushing and freeing fbufs in use.pelikan
This way, if fuse unmounts a FS without FBT_DESTROY, the fuse_mnt pointer is already invalidated. Also, on weird unmount situations with vnodes in use, vflush() them before doing fuse_device_cleanup(). Tested with ntfs-3g, ok syl@.
2013-12-03Add support for FBT_RECLAIM that allow us to free the representationSylvestre Gallon
of vnode in userspace. "I think it's right" from tedu@.

2013-12-03Add some missing check to know if the communication channel withSylvestre Gallon

2013-06-03add a bunch of files for ISC-licensed FUSE support. ok beck deraadtTed Unangst
from Sylvestre Gallon ccna.syl gmail.com. Many thanks to Sylvestre for all the hard work.
2013-04-15Add an f_mntfromspec member to struct statfs, which specifies the name ofJoel Sing
the special provided when the mount was requested. This may be the same as the special that was actually used for the mount (e.g. in the case of a device node) or it may be different (e.g. in the case of a DUID). Whilst here, change f_ctime to a 64 bit type and remove the pointless f_spare members. Compatibility goo courtesy of guenther@ ok krw@ millert@
2013-03-28Add support for _PC_TIMESTAMP_RESOLUTION for ffs/mfs, cd9600, ext2,Philip Guenther
msdos, NFS, fifos and devices, plus support for querying it in getconf(2) and the requisite pathconf(2) manpage blurb ok tedu@
2013-03-28Handle the pathconf _PC_PATH_MAX, _PC_PIPE_BUF, _PC_ASYNC_IO,Philip Guenther
_PC_PRIO_IO, and _PC_SYNC_IO names in VOP_PATHCONF(), as they're fs-independent for us. Since we don't support latter three on any fs, we can also define the related _POSIX_{ASYNC,PRIO,SYNC}_IO symbols in <unistd.h> (via sys/unistd.h) with value -1. Also, zap pointless tty-only values from procfs(!). ok beck@, deraadt@
2012-09-10Cleanup VFS mount string handling:Joel Sing
- Avoid using copyinstr() without checking the return value. - sys_mount() has already copied the path in, so pass this to the filesystem mount code so that it does not have to copy it in again. - Avoid copyinstr()/bzero() dance when we can simply bzero() and strlcpy(). ok krw@
2012-06-20Cleanup our filesystem pathconf() code a little bit to make it easierMatthew Dempsky
to diff against FreeBSD's. From Brad; no object file change on amd64.
2012-04-10Make the KERN_NPROCS and KERN_MAXPROC sysctl()s and the RLIMIT_NPROC rlimitPhilip Guenthe
count processes instead of threads. New sysctl()s KERN_NTHREADS and KERN_MAXTHREAD count and limit threads. The nprocs and maxproc kernel variables are replaced by nprocess, maxprocess, nthreads, and maxthread. ok tedu@ mikeb@
2012-03-23Make rusage totals, itimers, and profile settings per-process insteadPhilip Guenthe
of per-rthread. Handling of per-thread tick and runtime counters inspired by how FreeBSD does it. ok kettenis@
2012-03-10Add PS_EXITING to better differentiate between the process exiting andPhilip Guenthe
the main thread exiting. c.f. regress/sys/kern/main-thread-exited/
2012-02-20First steps for making ptrace work with rthreads:Philip Guenthe
- move the P_TRACED and P_INEXEC flags, and p_oppid, p_ptmask, and p_ptstat member from struct proc to struct process - sort the PT_* requests into those that take a PID vs those that can also take a TID - stub in PT_GET_THREAD_FIRST and PT_GET_THREAD_NEXT ok kettenis@
2011-12-24Remove the ability to ptrace via procfs, as no one is using it, so fixingPhilip Guenthe
and extending it to support rthreads would be a waste of time. Also, don't show rthreads in the process listing in procfs. Reassurances that compat_linux doesn't need this from ajacoutot@ ok kettenis@
