mycroft 967a4693f2 Set the B_NOCACHE bit so that NFSv3 will not try to do async writes. 1998-11-08 19:45:17 +00:00
jonathan 9a06d5e2a6 Compute compile-time value of old-VM parameter MAX_KMAPENT from NPROC
(2x NPROC plus slop) unless expclitly set. Use current constant value
(100) as a lower bound, as suggested by Chuck Cranor.

Move NPROC and other parameter definitions from param.c to param.h so
they are visible to vm/vm_map.h.

Systems with hand-tuned NPROC should now support that many processes.

chuck 1449d78fd3 remove the following if UVM is defined:
- share_map in vm_map_object.   UVM doesn't use share maps, so drop unused
	partial support for them to simplify the code.
 - is_main_map in vm_map.   no longer needed once share maps are gone.
 - vm_map_version_t.   map versions are handled elsewhere in UVM.

tv 8219f068e2 Declare silent success on madvise(). As an advisory call, it is harmless
to pretend success even though it's not supported, and some emulations
rely on its success.

mrg b5f69ff667 add a `char se_path[PATH_MAX]' member to struct swapent, that
the pathname of the swap device is saved into.  add a char *swd_path
member to struct swapdev, that contains a copy of the pathname
(using malloc(9)).  rename swapctl(2)'s SWAP_STATS to SWAP_OSTATS,
and add a new SWAP_STATS command (number).  make swapctl(SWAP_STATS,
...) [new version] copy the path out.  if COMPAT_13, also include
support for SWAP_OSTATS.  also fix a minor bug in swapctl(2).

the point of this is that swapfiles are now shown in `swapctl -l'.

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

thorpej 6626878e7b It is no longer necessary for pmap_pinit() and pmap_release() to be
pmap interface functions, as NetBSD no longer uses statically allocated
pmaps (except for the kernel pmap, which is special-cased anyhow).

mrg 6b11eea5b2 reject attempts to map an immutable or append-only file, shared with
write protection.  this stops data corruption where it was possible
to change the in-memory copy of an append-only file (but not the on-disk
copy).  this is documented in NetBSD security advisory 1998-003.  thanks
to darrenr, lukem, cgd, mycroft and mrg for this.

kleink afeaa5bb57 Use size_t to pass the length of the memory region to operate on to chgkprot(),
kernacc(), useracc(), vslock() and vsunlock(); (unsigned) ints are not
adequate on all platforms.

thorpej 73863dd3c9 Pass vslock() and vsunlock() a proc *, rather than implicitly operating
on curproc.

thorpej 2018d40811 Allocate kernel virtual address space for the U-area before allocating
the new proc structure when performing a fork.  This makes it much
easier to abort a fork operation and return an error if we run out
of KVA space.

The U-area pages are still wired down in {,u}vm_fork(), as before.

type is not supported (neither VREG nor VCHR, or not a vnode at all), fail
with ENODEV instead of EINVAL.

chuck 3d3a01805a correctly count ru_majflt. the fix pulled in from pr#1397 is incorrect.
calling vm_pager_get() doesn't count as a "majflt" unless the pager
returns VM_PAGER_OK.  when walking an object chain we can get VM_PAGER_FAIL
(indicating that the requested data does not reside in this object
and we must continue to walk the chain) -- we don't want to count this
as a majflt.

i also added code to count ru_minflt.
