cgd f784b878c2 ACCOUNTING define doesn't exist any more... 1993-10-20 23:04:33 +00:00
cgd 9ceb615f82 add some timeout_t typedefs 1993-10-20 00:53:34 +00:00
cgd fc8ee7437c knf'ify, clean up some, move sysacct() args out of function declaration. 1993-10-20 00:45:34 +00:00
cgd 287eb9a50e delete my '/dev/acct'-style accounting in favor of the version written by 
Mark Tinguely (tinguely@plains.NoDak.edu).  It's the 'standard' way
of doing accounting, rather than a wacky one.
 1993-10-20 00:16:40 +00:00
cgd 2ff9ed5060 fix my last change; for some reason i thought that 'p' was defined 
in these functions.  use curproc instead.
 1993-10-19 23:41:44 +00:00
cgd ddd610e422 from Mark Tinguely, with mods by davidg and then fially fixed by cgd. 
do the space-used integration, over time, for processes.
 1993-10-19 23:37:50 +00:00
cgd dfaa02a09b pay for block i/o. slightly different than how done by Mark Tinguely. 1993-10-19 02:47:56 +00:00
cgd dd818c7cd0 get rid of __main() -- it's going into libkern 1993-10-15 06:16:22 +00:00
deraadt c52686ddb3 from magnum branch: nbqd() was broken 1993-10-13 03:15:57 +00:00
cgd a84055b552 use the ALIGN macro to align the stack, rather than rounding up 
by a (char *).  the former is safe, even on strange machines
(read: sparc).
 1993-10-06 07:27:58 +00:00
cgd 714fa4716b changed the Debugger() call, which not all kernels have, to panic(), 
but only when DIAGNOSTIC is defined.
 1993-10-06 07:24:21 +00:00
cgd 772436479d new, improved, and rationally-implemented vfs_bio. no more serious 
structural changes should happen, as it now does the right thing
w.r.t. buffer resizing and having lots of buffers vs. relatively
little buffer space.  Ports can now "do the standard thing", re:
nbuf and bufpages, which is make nbuf = bufpages by default.
 1993-10-04 04:56:28 +00:00
mycroft 9a1fcf008b Update after fixing syscalls.master. 1993-10-02 09:55:09 +00:00
mycroft c05111e593 Put back the $'s in the RCS id that the last commit removed. 1993-10-02 09:51:40 +00:00
cgd e27f6e3ea0 patch from Christoph Badura <bad@flatlin.ka.sub.org> to fix credential 
use by read-ahead blocks.  This fixes those weak NFS authentication
messages, and allows us to use BSDI NFS servers again...
 1993-10-01 21:47:11 +00:00
cgd 1d0f22a29a convert to use the buffers which are (now) statically allocated at 
startup in machdep.c...  buffers are now *never* allocated after boot.
currently, the limitation that says bufpages must cover nbuf*MAXBSIZE
still exists, but this is one step closer to removing that limitation.
 1993-09-29 04:49:15 +00:00
cgd 4a21fe3648 ifdef out the ttyfree()'s, so that fill_eproc doesn't panic when 
a process's session still holds a ref to a tty which has been deallocated
and reused.
 1993-09-29 02:36:21 +00:00
cgd 94ac210002 rewrite biodone to the spec in the daemon book, and to account for 
the fact that buffers with B_CALL set shouldn't be brelse()'d.
 1993-09-21 00:40:02 +00:00
brezak 1905040ad2 Add sysarch() syscall. 1993-09-19 18:55:38 +00:00
cgd 9c32bc786a make allproc be volatile, and cast things accordingly. 
suggested by torek, because CSRG had problems with reordering
of assignments to allproc leading to strange panics from kernels
compiled with gcc2...

mycroft 40222e846f Fix from Noriyuki Soda <soda@sra.co.jp>:

        to pass file descriptors through UNIX domain socket.

jtc 070f4a7f50 Removed functions moved to libkern: strcpy, strcmp, strlen, ffs, etc. 1993-09-11 00:08:03 +00:00
phil de69711383 These changes are due to a mismatch with user functions prototyped as 
func(short) and the fact the the kernel uses full ints.  This caused
problems on the pc532 port.  These fixes take the good 16 bits passed
by the user program and converts them into the correct form for the
kernel.

sef b477be52eb Yet more of the ptrace() reorg; now ptrace_setregs() and ptrace_getregs() 
are present, along with PT_GETREGS and PT_SETREGS ptrace commands.
 1993-09-05 03:53:52 +00:00
cgd 15359c9f59 enable loadable execution handlers. need to do something better re: 
how much of the file to pass in the exec package, but i think the
solution to that will be to pass e.g. a disk block's worth, or whatever;
if exec handlers really need more, they've got the damned vnode.
 1993-09-05 01:36:28 +00:00
cgd 83aeee1bc0 there now exists an "exec switch". break the a.out code into another 
module, and tidy up the interface so that other object formats are
more easily supportable.

cgd a05bd46763 patch from Szabolcs Sziget <pink@bagira.fsz.bme.hu> to load lkm device 
drivers properly.
 1993-09-05 00:55:57 +00:00
sef fddf2c7605 ptrace_single_step() and ptrace_set_pc() should return errors if 
necessary.  (Mainly because the SPARC can't easily single step, so
it should return EINVAL, and then ptrace() should return that to the
user.)

cgd d365662684 ok, initialize that errno, to make theo and gcc2 happy... 1993-08-31 01:52:34 +00:00
cgd 518f7c78d6 a program being exec'd *must* cause *some* exec commands to be invoked; 
if it doesn't there's a problem in the kernel, because a program
with no exec commands run will have no address space except the stack,
and i don't think it's valid to have a "run from stack only" exec type,
so panic.  if need for that case comes up later, it can be changed...

cgd 54eb3b1f88 brought in fixed/renamed/matching MS-DOS FS code, from Jeff Polk 
<polk@bsdi.com>.  His notes are as follows:
------------------------------------------------------------------------------

 July 22, 1993

 - Changed name of entire package from PCFS to MSDOSFS

 - Fixed bugs:
      root directory size in clusters instead of bytes
      growing directory didn't update in-core size
      link, symlink, mknod didn't free locked parent (deadlock)
      lookup returned real error on create and rename instead of EJUSTRETURN
      rename changed `.' entry in child instead of name entry in parent
      rename removed `.' entry in child instead of removing entry in
              parent when moving a directory from one dir to another
      createde() left new node locked when write of parent failed (deadlock)
      removede() decremented refcount even on error (rmdir's which failed
              due to write errors left in-core cache entries inconsistent)
      changed validation for filesystem to not check for the boot signature
              since some disks (e.g., mtools) aren't bootable
      directories are always show current time as modify time
              (needed for NFS export since DOS never updates dir mod times --
               ctime is true create time).

 - Added support for cookies changes to the readdir() vnode
      interface (#ifdef __bsdi__)

 - Punted on the whole problem of inode generation numbers.  This means
   that there's a chance of using a stale file handle to access a new
   file, but it doesn't appear to be the common case, and I don't see
   how to generate reasonable generation numbers without changing something
   on the disk (which is the way the SVR4 filesystem survival kit guys
   did it).  I don't think it would be very safe to change the on-disk
   format.

        Jeff Polk (polk@BSDI.COM)

cgd cd56dd1638 merge in changes from netbsd-0-9-ALPHA2 1993-08-07 07:53:27 +00:00
cgd ea4defd6da do the Net/2 thing with startrtclock() for non-i386 architectures. 
i386's startrtclock should be moved down, as well, but i believe it
does some magic...
 1993-08-07 06:25:43 +00:00
cgd f5ec218873 the swtch() calls here should not need to be splclock() protected, 
and certainly don't need to be bracketed by splclock()/splnone(),
the latter of which is a jolitz invention.
 1993-08-07 05:16:38 +00:00
mycroft bbc8c11fd5 Nuke an extra `||' Chris inserted. 1993-08-03 02:45:20 +00:00
cgd d6b4910ac2 fix from Garrett Wollman <wollman@emba.uvm.edu> to return EPROTONOTSUPP 
if user tries to get a socket for a protocol with no usrreq function
 1993-08-03 01:36:10 +00:00
mycroft 5cc9898c12 Cosmetic change to VOP_ADVLOCK() fix. 1993-08-03 00:11:29 +00:00
mycroft f9ce597695 Collapse a bunch of `if (a & x) b |= x; else b &= ~x;' statements. 
Whoever wrote this fugly code must've been on drugs.
 1993-08-02 23:37:56 +00:00
mycroft 4862b84c92 Add RCS identifiers (this time on the correct side of the branch), and 
incorporate recent changes in netbsd-0-9 branch.
 1993-08-01 19:22:24 +00:00

cgd 9bd082f70e replace jolitz's vfs__bio with a better one from CMU via mw. 
so, replace vfs__bio, and deal with attendant changes.
 1993-07-19 16:38:35 +00:00
cgd 57ee917973 allocate out of kmem_map, not buffer_map. buffer_map is for 
*buffers*...  hopefully this won't fragment kmem_map too much.
it should probably be put into its own map, but doesn't need to be
right now.
