thorpej 9a3b52d482 Yay! This file is finally DEAD DEAD DEAD! 1998-02-18 07:17:13 +00:00
thorpej d1f0dbf1b1 Don't use vfssw[], it's gone; use vfs_list instead.
Implement vfs_attach() and vfs_detach(), which add and remove file systems
from the kernel.
1998-02-18 07:16:41 +00:00
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.

kleink f339e80ad6 Regen: syscalls.master change (addition of __posix_chown(), __posix_fchown(),
__posix_lchown(); posix_rename() -> __posix_rename()).
1998-02-14 20:05:53 +00:00
kleink 3404e6deb3 Implement __posix_chown(), __posix_fchown() and __posix_lchown(). Also,
rename posix_rename() to __posix_rename() to follow this convention.
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.

mrg 5ef401eaaf oops, forgot to add this file earlier. 1998-02-05 14:58:45 +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 66abe4217c Implement an activity log for malloc() and free(), useful for tracking
down "Data modified on freelist" and "muliple free" problems.

The log is activated by the MALLOCLOG option, and the size of the
event ring buffer is controlable via the MALLOGLOGSIZE option (default
is 100000 entries).

From Chris Demetriou, cleaned up a little by me per suggestions in the
e-mail from Chris that contained the code.

mrg a20d56e92e add new version of non contiguous memory code, written by chuck cranor,
called "MACHINE_NEW_NONCONGIG".  this is required for UVM, the new VM
system (also written by chuck) that is coming soon.  adds new functions:
	vm_page_physload() -- tell the VM system about an area of memory.
	vm_physseg_find() -- returns index in vm_physmem array that this
		address is in.
and several new versions of old functions/macros defined in vm_page.h.

this is the MI portion.  sparc, and then later i386 portions to come.
all other ports need to change to this ASAP!  (alpha is already being
worked on)

thorpej cbf3cc6bb8 Make insertion and removal of sockets from the partial and incoming
connections queues O(C) rather than O(N).
1998-01-07 23:47:08 +00:00
thorpej cc22126721 Implement passing credentials as ancillary data on Unix domain sockets,
enabled with the LOCAL_CREDS socket option on the listener.  Semantics are
similar to BSD/OS's:
- Creds are available with first data on SOCK_STREAM, and with every datagram
  on SOCK_DGRAM.
- It is not possible to forge credentials.

Different in that:
- Different credential data structure (ours does not rely on the format
  of internal kernel data structures, and does not pass the login name).
- We can pass creds and file descriptors at the same time (this does not
  work in BSD/OS).

Luke Mewburn <lukem@netbsd.org> gets credit for inspiring me to implement
this.  :-)

thorpej 2e85747e9e From 4.4BSD-Lite2 (noted by Frank van der Linden):
so_linger is used as an argument to tsleep(), so was stuffed with
clockticks for the TCP linger time.  However, so_linger is set directly from
l_linger if the linger time is specified, and l_linger is seconds (although
this is not currently documented anywhere).  Fix this to set the TCP
linger time in seconds, and multiply so_linger by hz when tsleep() is
called to actually perform the linger.
