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.

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.

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()).

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.
