fvdl 975751cda2 vinsheadfree -> ungetnewvnode 2000-06-27 23:51:51 +00:00
fvdl c39797c045 Add vinsheadfree, a small function to push vnodes that have just
been allocated by getnewvnode, back onto the head of the free list.
Needed in some VFS_VGET functions to deal with races.

mrg 2f159a1bac remove/move more mach vm header files:
<vm/pglist.h> -> <uvm/uvm_pglist.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.

pooka 7747299e6d Correct situation where vnode was left hanging around when trying to
mount a filesystem with securelevel 2. A second mount-attempt left
everything completely frozen.

Fix by Bill Sommerfeld.

cgd ef767ee388 Replace my personal attribution string ("This product includes software
developed by Christopher G. Demetriou for the NetBSD Project.") with
a generic NetBSD one ("This product includes software developed for the
NetBSD Project.  See http://www.netbsd.org/ for information about NetBSD.")
so that this same set of terms can be used by others if they so desire.
(Eventually i'll be converting more/all of my code.)

chs b4aac1046f round the sizes of mapped text and data segments to PAGE_SIZE.
fixes PR 10079.
2000-06-13 06:21:51 +00:00
chs ded9898d88 make sure that the size we pass to uvm_map() is a multiple of PAGESIZE.
this should fix PR 10175 and prevent the panic of PR 10079.

simonb e907fee281 In the KERN_GETPROC* handler:
* Handle KERN_PROC_SESSION that has been defined in <sys/sysctl.h> from
  day one.
* Add handlers for KERN_PROC_GID and KERN_PROC_RGID.
* If "op" doesn't valid, return EINVAL.

sommerfeld c0011ad705 Fix several problems with lockf/fcntl byte range locks:
- document a data structure invariant in lockf.h
 - add KASSERT() to check the invariant.
 - be more consistent about dequeuing ourselves from the blocked list
after a tsleep().
 - Fix two places where the invariant is violated.
 - correct a few comments here and there
 - If we're still following a lock dependancy chain after maxlockdepth
processes and haven't gotten back to the start, assume that we're in a
cycle anyway and return EDEADLK.

Fix is a superset of an existing fix in FreeBSD, but independantly
derived.

Fixes kern/3860.

sommerfeld e964d558a7 Fix assorted bugs around shutdown/reboot/panic time.
- add a new global variable, doing_shutdown, which is nonzero if
vfs_shutdown() or panic() have been called.
- in panic, set RB_NOSYNC if doing_shutdown is already set on entry
so we don't reenter vfs_shutdown if we panic'ed there.
 - in vfs_shutdown, don't use proc0's process for sys_sync unless
curproc is NULL.
 - in lockmgr, attribute successful locks to proc0 if doing_shutdown
&& curproc==NULL, and  panic if we can't get the lock right away; avoids the
spurious lockmgr DIAGNOSTIC panic from the ddb reboot command.
 - in subr_pool, deal with curproc==NULL in the doing_shutdown case.
 - in mfs_strategy, bitbucket writes if doing_shutdown, so we don't
wedge waiting for the mfs process.
 - in ltsleep, treat ((curproc == NULL) && doing_shutdown) like the
panicstr case.

Appears to fix: kern/9239, kern/10187, kern/9367.
May also fix kern/10122.

thorpej 6ea30ef2e8 Use ltsleep(). 2000-06-08 05:50:59 +00:00
thorpej fcc7898856 Change tsleep() to ltsleep(), which takes an interlock argument. The
interlock is released once the scheduler is locked, so that a race
between a sleeper and an awakener is prevented in a multiprocessor
environment.  Provide a tsleep() macro that provides the old API.

thorpej 0a3a6e34f8 Oops, missed a couple of places where CMSG_*() should be used. No
functional change in this case, but the code is now correct.

thorpej 724a90318e - Fix file descriptor passing AGAIN. This has apparently been broken
on LP64 systems (and probably the SPARC) since the __cmsg_alignbytes()
  changes went in.
- Change file descriptor passing to use CMSG_DATA(), not (cm + 1).  This
  pretty much has to be done in order to make it work properly on LP64,
  and considering that it's been broken this long...
- Use CMSG_SPACE() to determine the mbuf length needed for a given
  control message, and CMSG_LEN() to stash in the cmsg_len member.

thorpej 5b281c5932 Move schedticks and cp_time into schedstate_percpu. Also, allow
non-primary CPUs to call hardclock(), but make them bail about
before updating global timekeeping state (that's the job of the
primary CPU).

simonb 7e6435a651 White space nit in previous. 2000-06-02 16:05:49 +00:00
simonb 38cc1b3975 Add new sysctl node "KERN_SYSVIPC_INFO" with "KERN_SYSVIPC_MSG_INFO",
"KERN_SYSVIPC_SEM_INFO" and "KERN_SYSVIPC_SHM_INFO" to return the
info and data structures for the relevent SysV IPC types.  The return
structures use fixed-size types and should be compat32 safe.  All
user-visible changes are protected with
	#if !defined(_POSIX_C_SOURCE) && !defined(_XOPEN_SOURCE)

Make all variable declarations extern in msg.h, sem.h and shm.h and
add relevent variable declarations to sysv_*.c and remove unneeded
header files from those .c files.

Make compat14 SysV IPC conversion functions and sysctl_file() static.

Change the data pointer to "void *" in sysctl_clockrate(),
sysctl_ntptime(), sysctl_file() and sysctl_doeproc().
2000-06-02 15:53:03 +00:00
cgd 00b28e7a52 another mod of opportunity: const poison. (cfprint_t should take
const char * as second arg, too, but that's Hard.)  also, convert use
of "(char *)0" to NULL.

thorpej 956b3ca3b3 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.

sommerfeld 879eaa480a Fix clearing of ktrace points:
- need deep compare of open files, not a shallow pointer compare.
 - reorder fdrelease()/FILE_UNUSE() invocations so fdrelease doesn't
block waiting for something which can't happen until after it returns.
