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@
2011-07-04move the specfs code to a place people can see it; ok guenther thib krwTheo de Raadt

2011-07-02kqueue attach functions should return an errno or 0, not a plain 1. FixNicholas Marriott
the obvious cases to return EINVAL and ENXIO. ok tedu deraadt
2011-04-05Remove portalfs.Thordur I. Bjornsson
While it is a terribly cool idea, it's just awful and since noone has stepped up to the plate to keep it up with the current vop state, retire it to the attic. ok krw@, deraadt@, guenther@, miod@. comments from jmc@
2011-04-05Every single vop_default is set to eopnotsupp, so retire itThordur I. Bjornsson
and return EOPNOTSUPP directly from the VOP_* functions. Filesystems should, at some point fill in every function in the vop_default struct so we can get rid of the 'if' statements in VOP_*.
2011-04-02Move P_SUGID and P_SUGIDEXEC from struct proc to struct process, soPhilip Guenthe
that you can't evade the checks by doing the dirty work in an rthread ok blambert@, deraadt@
2010-12-21Bring back the "End the VOP experiment." diff, naddy's issues whereThordur I. Bjornsson
unrelated, and his alpha is much happier now. OK deraadt@
2010-09-23In procfs_root(), while the vn_lock on a newly-allocated vnode can notOwain Ainsworth
fail it is still good practise to either check the return value or to provide a flag that won't (to avoid copy pasted code that gets it wrong). So change LK_EXCLUSIVE to LK_EXCLUSIVE | LK_RETRY, removing the one caller of vn_lock in the tree that doesn't either pass LK_RETRY or check the return value. ok thib@, jsing@ as part of a larger diff.
2010-09-10Backout the VOP diff until the issues naddy was seeing on alpha (gcc3)Thordur I. Bjornsson
have been resolved.
2010-09-06End the VOP experiment. Instead of the ridicolusly complicated operationThordur I. Bjornsson
vector setup that has questionable features (that have, as far as I can tell never been used in practice, atleast not in OpenBSD), remove all the gunk and favor a simple struct full of function pointers that get set directly by each of the filesystems. Removes gobs of ugly code and makes things simpler by a magnitude. The only downside of this is that we loose the vnoperate feature so the spec/fifo operations of the filesystems need to be kept in sync with specfs and fifofs, this is no big deal as the API it self is pretty static. Many thanks to armani@ who pulled an earlier version of this diff to current after c2k10 and Gabriel Kihlman on tech@ for testing. Liked by many. "come on, find your balls" deraadt@.
2010-07-26Correct the links between threads, processes, pgrps, and sessions,Philip Guenthe
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
2010-07-17Wrap kernel function declarations in #ifdef _KERNEL to eliminate warningsPhilip Guenthe
when the header is used by userspace. ok miod@

2010-05-18dont let sys/ioctl.h imply that you get the ioctls in dkio.h. thisDavid Gwynne
gets rid of #include <sys/dkio.h> in sys/ioctl.h and adds #include <sys/dkio.h> to the places that actually want and use the disk ioctls. this became an issue when krw@'s X build failed when he was testing a change to dkio.h. tested by krw@ help from and ok miod@

same diff as before, with the uninitalized variable fixed. ok toby@
2009-07-09Remove the VREF() macro and replaces all instances with a call to verf(),Thordur I. Bjornsson
which is exactly what the macro does. Macro's that are nothing more then: #define FUNCTION(arg) function(arg) are almost always pointless and should go away. OK blambert@ Agreed by many.
2009-06-25backout the buf_acquire() does the bremfree() since all callersThordur I. Bjornsson
where doing bremfree() befure calling buf_acquire(). This is causing us headache pinning down a bug that showed up when deraadt@ too cvs to current, and will have to be done anyway as a preperation for backouts. OK deraadt@

Just put it in the buf_acquire function. oga@ ok

a locking botch in portal_open(); - set f_namemax at mount time and use copy_statfs_info() in portal_statfs(); This diff is a slight tweak of the diff sent in PR5968 by Frank Denis (j at pureftpd.org) Thanks!

2008-06-12Bring biomem diff back into the tree after the nfs_bio.c fix went in.Theo de Raadt
ok thib beck art
2008-06-11back out biomem diff since it is not right yet. Doing very largeTheo de Raadt
file copies to nfsv2 causes the system to eventually peg the console. On the console ^T indicates that the load is increasing rapidly, ddb indicates many calls to getbuf, there is some very slow nfs traffic making none (or extremely slow) progress. Eventually some machines seize up entirely.
2008-06-10Buffer cache revampBob Beck
1) remove multiple size queues, introduced as a stopgap. 2) decouple pages containing data from their mappings 3) only keep buffers mapped when they actually have to be mapped (right now, this is when buffers are B_BUSY) 4) New functions to make a buffer busy, and release the busy flag (buf_acquire and buf_release) 5) Move high/low water marks and statistics counters into a structure 6) Add a sysctl to retrieve buffer cache statistics Tested in several variants and beat upon by bob and art for a year. run accidentally on henning's nfs server for a few months... ok deraadt@, krw@, art@ - who promises to be around to deal with any fallout
2008-06-09Update access(2) to have modern semantics with respect to X_OK andTodd C. Miller
the superuser. access(2) will now only indicate success for X_OK on non-directories if there is at least one execute bit set on the file. OK deraadt@ thib@ otto@

2008-05-03Introduce vop_generic_bmap(); use it where applicable.Thordur I. Bjornsson
one thing of note, fifofs changes in that its bmap now sets the runp too 0, but that was an oversight in the old code. ok art@

2007-12-27fifofs, deadfs and specfs all have the same "trivial lookup routine thatThordur I. Bjornsson
