cgd 008f5aedf9 apply patch from PR 2788 (from Dennis Ferguson <dennis@jnx.com>) to
more smoothly apply "tickfix"es microsecond deltas (when compensating
for clocks running at > 1000Hz).
1997-01-15 04:59:39 +00:00
cgd 99fb250b5c fix from PR 2787 (from Dennis Ferguson <dennis@jnx.com>): when adjtime
is running (and NTP is not enabled), the adjtime()-handling code clobbers
any tickfix that may be necessary for systems with clocks with frequency
greater than 1000Hz.

perry b89a3425b7 Eliminate obsolete TIMEZONE and DST options.
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.

cgd 7e31391b10 update for new syscalls.master 1996-12-22 08:05:47 +00:00
cgd acad90d846 * (slight) general cleanup
* change in-kernel syscall prototypes to match user-land prototypes in
  the following ways:
    + add 'const' where appropriate.
    + make the following "safe" type changes where appropriate:
	caddr_t -> struct msghdr *
	caddr_t -> struct sockaddr *
	caddr_t -> void *
	char * -> void *
	int -> uid_t (safe because uid_t not used as index/count)
	int -> gid_t (safe because gid_t not used as index/count)
	u_int -> size_t
    + change "int" to "u_long" in flags arguments to chflags() and
      fchflags().  This is safe because the arguments are used as
      flag bits and there's nothing that would cause the top bit
      of the int to be set yet, and because the user-land definitions
      already specified u_long, so a u_long's worth of argument was
      already being passed in.

cgd 997ec138ad change ntp_gettime's struct ntptimeval *'s name to match kern_ntptime.c 1996-12-22 07:47:43 +00:00
cgd c99936a735 * fix return types. previously, most things returned 'int.' which was
wrong for a bunch of functions:
	void:		sys_exit, sys_sync
	ssize_t:	sys_read, sys_write, sys_recvmsg, sys_sendmsg,
			sys_recvfrom, sys_readv, sys_writev, sys_sendto
	long:		sys_pathconf, sys_fpathconf
	void *:		sys_shmat

* Note that sys_open, sys_ioctl, and sys_fcntl are defined such that their
  last argument is optional.

These changes should not have any real effect, because right now this
information is not actually used for anything.

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

  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!)
