kleink 4648a78bba Regen: addition of fdatasync(). 1998-06-05 20:36:53 +00:00
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.

thorpej 7a239c12c6 In vfs_unmountall(), if curproc is NULL, abort, because unmounting

kleink 5d9a1f3207 Regen: syscalls.master changed. 1998-03-27 13:09:52 +00:00
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.

thorpej b436157e65 Make proc0 use the statically-allocate vmspace0 again, and make it use
the kernel's pmap, since proc0 (and other that share its address space)
are kernel-only processes, and should never contain userspace mappings.

This makes it easier to detect errors, like entering user mappings
for kernel processes, in pmap modules, and makes some sense, considering
that kernel processes are really just "thread contexts" for the kernel.
1998-03-27 01:52:01 +00:00
thorpej 272d8a4a38 Process 2 (the pagedaemon) always runs in kernel space, so share VM

thorpej 6c57a3c322 Change vfs_opv_init_explicit() to not allocate the vnode operations
vectors; defer that to vfs_opv_init().

Change the interface to vfs_opv_init() and export it; it now takes a
pointer to an array of vnodeopv_desc *'s to initialize.  Allocate
the vnode operations vectors here.  Called by vfs_attach().

Implement vfs_opv_free(), which deallocates the vnode operations
vectors.  Called by vfs_detach().

Change vfsinit() to build the initial vfs_list by traversing the
vfs_list_inital[] table, and vfs_attach()'ing those file systems.
Also, initialize special vnodeopv_descs (dead, fifo, spec) which
are not associated with any particular file system.

1998-02-14 20:01:05 +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.
