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.

mycroft 11c9f28f0e Update comment. 1997-10-19 03:29:20 +00:00
enami db7f1ad2ad Check read permission of symbolic link in vfs layer, when doing readlink(2). 
Suggested by der Mouse.  Ok'ed by Jason R. Thorpe.
 1997-10-11 00:05:15 +00:00
fvdl 541b204984 Add vn_readdir function for use in both the old getdirentries and 
the new getdents(). Add getdents().
 1997-10-10 02:09:30 +00:00
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.
 1997-10-03 13:29:20 +00:00
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.
 1997-08-25 19:31:43 +00:00
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.

mikel b0e7d3c13b sync filesystems in reverse order. suggested originally by Jim Rees 
<rees@citi.umich.edu>, with some updating by Greg Hudson <ghudson@mit.edu>.

tls 4b1213d27c sync needs to clean VM objects backed by vnode pagers 1997-02-13 02:54:06 +00:00
fvdl c745cba077 If the target for a rename() call exists, it will be removed. So, don't 
leave any pages around (i,e, insert a vnode_pager_uncache()).
 1997-02-10 12:41:19 +00:00
cgd e7af2a8237 * catch up with system call argument type fixups/const poisoning. 
* Fix arguments to various copyin()/copyout() invocations, to avoid
  gratuitous casts.
* Some KNF formatting fixes
 1996-12-22 10:21:06 +00:00
cgd 6d3337bdf6 permit MNT_NOCOREDUMP as a generic mount flag. 1996-10-23 23:07:08 +00:00
jtc 4039b6bcba Return ESPIPE when filedes is associated with a FIFO. 1996-10-21 17:42:48 +00:00
mycroft 584810c846 Implement futimes(). 1996-04-23 10:29:02 +00:00
thorpej 44dcfee5ea Move an #ifdef FIFO so this compiles on a SPARC (-Wall) if FIFO is not 
defined.
 1996-03-22 06:51:04 +00:00
fvdl 6c53a8d22f Remove previously introduced bug: always make sure mappings of a removed 
file don't stick around.

christos 09afd77655 More proto fixes 1996-02-09 18:59:18 +00:00
mycroft 06a1236be9 Rearrange the locking in sys_unlink(), more like nfsrv_remove(). 1996-02-09 15:39:12 +00:00
mycroft 53fccab940 Fix vop_link, vop_symlink, and vop_remove semantics in several ways: 
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.
 1996-02-09 14:45:36 +00:00
mycroft 7366dec9ec No need for LOCKPARENT in sys_lstat(), and eliminate dead variables. 1996-02-08 02:54:20 +00:00
jtc d9d402d0fb Revert to sane symlink semantics. This something we should have done 
long ago.  Fixes many PRs.

christos e630447d8c First pass at prototyping 1996-02-04 02:17:43 +00:00

mycroft 99686e0059 Add a vnode** argument to getvnode(), prototype it, and make it return 
EBADF if the file descriptor has been revoked.
