enami 9ccb5d2e4d Add system call lchmod (#274), lchown (#275) and lutimes (#276). 1997-10-03 15:06:18 +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).

thorpej a2721a0f1b In vfs_shutdown(), do the "sync and wait for it to finish" _before_
unmounting all of the file systems.  If we encounter a condition where
all of the dirty buffers could not flush, then don't unmount file systems,
since it might be likely to wedge.

leo d4713d24c2 Implement the kernel part of pr-1891. This allows for a more flexible sized
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

1997-06-26 06:13:36 +00:00
thorpej 1351e629b3 Several small changes to eliminate kludginess in dealing with unix domain
socket names:
- In unp_setsockaddr() and unp_setpeeraddr(), if the socket name can't
  fit into a single mbuf, allocate enough external storage space to
  hold it.
- In unp_bind() and unp_connect(), perform a similar operation, but allocate
  one extra byte, and ensure that the pathname is nul-terminated.
Many thanks to enami tsugutomo <enami@cv.sony.co.jp> for the sanity
checking.
1997-06-26 06:06:40 +00:00
thorpej e1fb68eb29 In sockargs():
- Add a comment describing my feelings about this interface, in general.
- Remove the COMPAT_OLDSOCK length hack.  Instead, if the socket argument
  is too long to fit in an mbuf, allocate enough external storage to
  hold it.
- If the socket argument is a sockaddr, don't allow the length to be
  greater than 255, as that would overflow sa_len.
Many thanks to enami tsugutomo <enami@cv.sony.co.jp> for his sanity checking.
1997-06-26 06:01:59 +00:00
thorpej 01cbda9800 In sbappendaddr(), if the sockaddr length is larger than will fit in

  Inspired by PR #3770, from Havard Eidnes <he@vader.runit.sintef.no>.
- For SO_SNDLOWAT and SO_RCVLOWAT, don't let the low-water mark get
  set above the high-water mark.  Behavior is now consistent with
  BSD/OS: If such an attempt is made, silently truncate to the high-water
  value.

thorpej 91f7efbaf9 Fix crash dump device selection after the recent swap changes:
- If RB_ASKNAME, prompt for the dump device, defaulting to
  partition 'b' of the root device, if the root device is a disk.
- Else, if dumpspec is set to "none", do not configure a dump device.
- Else, if dumpspec is set by config(8), attempt to use that device.
- Else, dumpspec is wildcarded or unspecified; if the root device is
  a disk, select partition b.  (which was the previous default dump
  partition)

Note, dumps to a local disk now work even if root is on nfs.

thorpej 2a4b742e6a Update and enhancement to the mbuf code, to support use of non-cluster
external storage.  Highlights:

	- additional "void *" argument to (*ext_free)(), an opaque
	  cookie for use by the free function.
	- MCLALLOC() and MCLFREE() calls are gone.  They are replaced
	  by MEXTADD() (add external storage to mbuf), MEXTMALLOC()
	  (malloc() external storage and attach to mbuf), and
	  MEXTREMOVE() (remove external storage from mbuf).
	- completely new external storage reference counting
	  mechanism; mclrefcnt[] is gone.

These changes will eventually be used to pass driver DMA buffers up
the network stack, and reduce/eliminate copies in certain code paths
(e.g. NFS writes).

cgd 747448fc3e mark syscall() and __syscall() as INDIR syscalls 1996-12-22 06:46:50 +00:00
cgd 0e9ddb9039 * Don't actually output args structure definitions for INDIR syscalls (typo).
* Don't output prototypes for INDIR syscalls (since they always show up as
  sys_nosys() in the syscall table).
* Add "indir" to the comment for INDIR syscalls in the syscalls table, so
  it's more obvious why they call sys_nosys().

cgd ba32ea9a68 update copyright date 1996-12-22 06:33:46 +00:00
cgd 286395d1b3 * remember (i.e. don't throw away) system call return types.
* Deal with multi-word system call return types (i.e. foo *, or
  struct foo *, or struct foo, etc.).
* Add a new class of system calls "INDIR" (for "indirect"), which
  is to be used to represent indirect syscalls like syscall() and
  __syscall() which are implemented in MD code and which don't want
  args structures defined.  (The old way of declaring this type of
  syscalls still works.)
* Allow system calls to be marked as having a variable number of
  arguments, by inserting "..." (no trailing comma) before the
  first hf the optional arguments in the syscall definition.  Because
  of the way syscall arguments are handled by MI code, _ALL_ syscall
  arguments must actually be included in the definition, i.e.
  "optional" arguments are either "are there or aren't," i.e. these
  aren't really varargs functions.  Therefore, for normal syscalls,
  there _must_ be arguments listed after the "...".  For INDIR
  syscalls, which really do have a variable number of arguments and
  which aren't handled via the normal mechanism, that requirement is
  not in force.
* output primitive (machine-parsable) syscall descriptions as comments
  in <sys/syscall.h>.  These can be used to easily build real function
  prototypes, or to build stub functions for use by lint.

cgd 66764a1a2f Check for a new definition, __BROKEN_INDIRECT_CONFIG, and if it is _not_
defined:
	define match functions to take a struct cfdata * as their second
	argument, config_search() to take a struct cfdata * as its second
	argument, and config_{root,}search() to return struct cfdata *.

	remove 'cd_indirect' cfdriver element.

	remove config_scan().

	remove config_make_softc() as a seperate function, reintegrating
	its functionality into config_attach().

Ports will define __BROKEN_INDIRECT_CONFIG until their drivers prototypes
are updated to work with the new definitions, and until it is sure that
their indirect-config drivers do not assume that they have a softc
in their match routine.

thorpej f85bef61f1 Include sys_getfh() if NFSSERVER || NFSCLIENT. 1996-12-03 00:28:31 +00:00
thorpej f02e8b3cf0 Make NFSSERVER work without NFSCLIENT. This is achieved by splitting
the client and server/shared data initialization into separate functions,
and calling the server/shared initialization directly from main().
Problem noted in PR #1308 (Kenneth Stailey) and PR #1780 (Chris Demetriou).
Fix suggested in PR #1780 by Chris Demetriou, and munged a bit by me,
and OK'd by Frank van der Linden <fvdl@netbsd.org>.

cgd 3340f02c2b fix two problems with shutdown hook code:
(1) after removing a shutdown hook (in shutdownhook_disestablish()),
    free it.  We created it, we have to free it.  Without this,
    shutdownhook_disestablish() leaks memory.
(2) in doshutdownhooks(), before running each hook, remove it from the
    shutdown hook list.  This makes sure that every hook is tried once
    (because doshutdownhooks() is called from before rebooting, and
    a fault in a shutdown hook will cause doshutdownhooks() to be called
    again), but prevents the hooks from potentially being run infinitely
    (as used to be possible, in the above-mentioned situation).

cgd e77b6879f7 Feature:
If not compiled with -D_KERNEL, include different includes and
do so macro magic so that this will fit sanely into test harnesses.
When used in user-land, this should be compiled with -D_EXTENT_TESTING.

Bug fixes:
(extent_insert_and_optimize) You can't do things like:
	LIST_REMOVE(elem->...le_next, ...);
	free(elem->...le_next, ...);
They just don't work (and will corrupt your list and/or malloc free list).

(extent_alloc_region_descriptor) Unless you wait, malloc can fail.
Don't accidentally deref a potentially-NULL pointer.

thorpej 9d9479eb2f Make ntp_gettime() and ntp_adjtime() like other system calls:
- The functions that implement them and the argument names are
  prepended with "sys_".
- Optional systems calls are "UNIMPL" if the support is not being
  compiled into the kernel.

thorpej 156e926117 Implement bitmask_snprintf(), which takes a value and a string
representing the names of those bits, prints them into a buffer
provided by the caller, and returns a pointer to that buffer.
Functionality is identical to that of the (non-standard) `%b' printf()
format, which will be deprecated.

Rename the non-exported function ksprintn() to ksnprintn(), and change
it to use a buffer provided by the caller, rather than at static
buffer.

jonathan bbcd2bb1ef Elf32 fixes for mips shared libraries:
* handle interpreters with nonzero virtual address of entry-point:
   subtract p_vaddr from computed entrypoint, as the mips elf exec did.

 * Add #ifdef ELF_INTERP_NON_RELOCATABLE/#endif around the code
   that tries to choose a `good' address at which to load an interpreter,
   if none was set by the emul probe  function.
   (the address chosen could be improved to avoid  fragmenting the
    process virtual address space).

 * define ELF_INTERP_NON_RELOCATABLE in machine/elf_machdep.h for mips CPUs,
   which currently use a GNU-derived ld.so.

ELF_INTERP_NON_RELOCATABLE is not necessary for native NetBSD/alpha ELF
binaries. It may be required for GNU-derived ELF dynamic loaders (Linux/i386?)

thorpej 26a25a87b2 Optimization of soqinsque() and soqremque():
Keep queue of pending sockets in a double linked list.  Previously,
a singly linked list was used, giving O(N) insertion/deletion times,
and was a major time consumer for sockets with large pending queues.
The double linked list give O(C) insertion/deletion times with only
a small cost in complexity.

Since a socket can be on, at most, one queue at a time, both so_q and
so_q0 can safely be used as (forward and backward, respectively) queue
pointers.

Submitted my Matt Thomas <matt@3am-software.com>, a long time ago.
(Geez, I've been running with this patch for _months_, and had completely
forgotten about it!)

modified.)  Propagate the const poisoning to code that uses the namei
