kenh b519a199d6 Pass MNT_NODEVMTIME flag to lower VFS layer. 1998-12-01 23:17:25 +00:00
tls 6321478a33 At securelevel >=2, don't allow new mounts, only allow change from rw to ro. 1998-11-14 06:38:54 +00:00
thorpej 2f3f9379cf Add a couple more file systems to mountcompatnames[] (even though they
didn't exist in 4.3BSD or NetBSD 0.9) and always put the table into
the kernel.  It's going to be needed for VFS sysctls.

perry 275d1554aa Abolition of bcopy, ovbcopy, bcmp, and bzero, phase one.
bcopy(x, y, z) ->  memcpy(y, x, z)
ovbcopy(x, y, z) -> memmove(y, x, z)
   bcmp(x, y, z) ->  memcmp(x, y, z)
  bzero(x, y)    ->  memset(x, 0, y)

kleink e9d6f5e996 Per IEEE Std 1003.1b-1993, implement the fdatasync() system call which is
identical to fsync() with the expecption of not being required to synchronize
file status information.
1998-06-05 20:31:36 +00:00
kleink 382743ada3 Convert fsync vnode operator implementations and usage from the old `waitfor'
argument and MNT_WAIT/MNT_NOWAIT to `flags' and FSYNC_WAIT.

kleink 3a1500efe9 Per X/Open CAE Spec Issue 5 Version 2, change the buffer size argument of
readlink() from type `int' to type `size_t'.  This isn't an ABI change, since
the calling convention of our only LP64 platform (the Alpha) already promotes
this argument to a `long'.

This may not be the final action on this matter; readlink() still returns
an `int', which may change in a future revision of the standard.

kleink 071ab13ebb Move the permission check in change_owner() back to ufs_vnops::ufs_chown()
again - the facility required in this context would be a filesystem-specific
super-user determination, which is not available yet.  Also, add some
clarification to a comment.

fvdl e5bc90f40c Merge with Lite2 + local changes 1998-03-01 02:20:01 +00:00
kleink 3ef309317a * Factor out some permission-checking code from ufs_setattr() into
change_owner().
* Change the semantics of chown(), fchown() and lchown(): when requesting a
  change of the owner of a file, clear the set-user-id bit; analogous behaviour
  for group changes.
* Since the above is a violation of the semantics specified by POSIX and
  X/Open, add corresponding compatibility syscalls: __posix_chown(),
  __posix_fchown(), __posix_lchown().  (Neither fchown() nor lchown() is
  specified by POSIX; the prefix is intended to reflect the semantics.)
* Rename posix_rename() to __posix_rename() to follow the above convention.

mrg d90485202c - add defopt's for UVM, UVMHIST and PMAP_NEW.
- remove unnecessary UVMHIST_DECL's.
1998-02-10 14:08:44 +00:00
mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

thorpej ec98cfce8a sys_mount(): Use vfs_getopsbyname() rather than groveling the vfssw[]
manualls.
1998-02-03 09:11:55 +00:00
kleink 087ac96d12 Update to last commit: do not pass the accounting flag to suser(), since the call does not actually *use* super-user privileges. Pointed out by Charles. 1997-12-21 18:50:57 +00:00
kleink aa4d1febf1 Due to the feedback received, change chown(), fchown() and lchown() not to
clear the setgid and setuid bits if called by the superuser.  Addresses
PR kern/4662.

enami 4589c896eb Conditionalize the recognition of symbolic link permission by
per fs mount option `symperm'.

thorpej 14cd99880c Fix the shared library versioning snafu caused by the recent changes
to the stat(2) family and msync(2).  This uses a primitive function
versioning scheme.

This reverts the libc shared library major version from 13 to 12, and
adds a few new interfaces to bring us to libc version 12.20.

From Frank van der Linden <fvdl@NetBSD.ORG>.

mycroft 9341cad610 After conversion of the file flags, if neither FREAD nor FWRITE is set,
return EINVAL.

Suggested by der Mouse.  Ok'ed by Jason R. Thorpe.

thorpej b4b543bc6f In sys_mount(), use vfs_getopsbyname() rather than using an explicit
reference to vfssw[].
1997-10-09 00:39:19 +00:00
thorpej c08ce9b419 If COMPAT_09 or COMPAT_43 are defined, include a table of "mount compatnames",
which maps the old file system index numbers to the new (well, since after
NetBSD 0.9) string-based method of finding a file system ops vector.  Use
this table rather than assuming the ordering of the vfssw[] array when
emulating the old mount system call.
1997-10-06 09:19:11 +00:00
enami 83d3cd0ec7 New function sys_lchmod(), sys_lchown() and sys_lutimes() to manipulate
symbolic links.
1997-10-03 14:44:26 +00:00
enami ea531316f0 - New function change_mode() to set mode given a vnode.
- New function change_utimes() to set access and modification times
  given a vnode.
- In the function sys_chmod() and sys_fchmod(), call change_mode().
- In the function sys_utimes() and sys_futimes(), call
  change_utimes().
1997-10-03 14:14:36 +00:00
enami a117f2d89b Reorder some piece of code;
In the function sys_utimes, do NDINIT() and namei() first.
In the function sys_futimes, do getvnode() first.
1997-10-03 13:46:02 +00:00
enami dec1d15959 In the function sys_chmod and sys_utimes, use VOP_UNLOCK(vp) and vrele(vp)
instead of vput(vp).
1997-10-03 13:37:33 +00:00
enami ba054536f8 Fold lone line to fit column < 80. 1997-10-03 13:32:06 +00:00
enami 9f882ea0ee Cosmetic change;
(error = ...) -> (error = ...) != 0, like other place.

kleink 66105c37fc Lseek(2) usage cleanup: the use of L_SET/L_INCR/L_XTND is deprecated,
use SEEK_SET/SEEK_CUR/SEEK_END instead.

fvdl b5e26aee04 Invalidate publicly exported FS info when unmounting it locally. 1997-06-24 23:44:57 +00:00
kleink d3aadd8976 Add posix_rename() syscall. 1997-05-18 19:56:48 +00:00
mycroft e3f99a9397 Pass the vnode type to vaccess(), and use it when checking VEXEC. Make sure
that the mode bits passed to vaccess() and returned by foo_getattr() contain
only permission bits.
1997-05-08 16:19:43 +00:00
mycroft 837a72363d VEXEC -> VLOOKUP, as appropriate. 1997-05-08 10:57:17 +00:00
mycroft d7f33c5e60 va_mode contains stat bits. Use S_IS[UG]ID rather than VS[UG]ID. 1997-05-08 10:19:10 +00:00
kleink 29c5707479 * Make chown()/fchown() use a piece of common code to set ownership.
* Setting the ownership of a file now implies clearing its set-{group,user}-id
  bits.
1997-04-30 19:29:43 +00:00
kleink e490ffb5cc Addendum to last commit: "simplify" usage of a vnode pointer. 1997-04-11 22:08:28 +00:00
kleink 589549e022 Use VOP_SEEK() in lseek(2). 1997-04-11 22:03:58 +00:00
kleink 116d655640 Back out POSIX.1 conformance change to lseek(2); this will be attended to
in a different way.
1997-04-09 23:26:06 +00:00
kleink 9300dedf8e Back out last change to rename(2) until a sane solution for the coexistence
of both BSD and POSIX semantics is available.
1997-04-07 00:04:16 +00:00
kleink 9d8538dd8b Changed lseek(2): return EINVAL upon attempt to seek to negative offset. 1997-04-04 13:57:06 +00:00
kleink 50ccaeca39 Converted rename(2) to proper POSIX.1 behavior: if "from" and "to"
are links to the same file, do nothing. This also eliminates the
previous (and incorrect) check, which was far more complicated.
1997-04-04 13:32:48 +00:00
fvdl 9599f78147 Add missing part of MNT_NOATIME commit: add it to the flags that can
be set by the mount system call.
1997-03-13 20:20:39 +00:00
fvdl 0538233e2c Implement changes to make fix for NQNFS and MFS unmounting (race conditions)
work. Not quite as good as with the Lite2 merges, but it'll do until then.

* dounmount() expects to be called with the mountpoint marked busy
* all callers of dounmount() thus make the call themselves
* if a filesystem was being unmounted, and we're woken up in vfs_busy(),
  don't reference the mountpoint struct pointer, as it has very probably
  been freed.
