cgd 436e431478 BSDI official patch #15: 
SUMMARY:
    "panic: vrele: null vp", the problem seems to be that two renames are
    moving the same source, and the second one can't do it.
ALSO:
    in sync, check that rootfs is non-null before using it.

cgd 299ff91b14 BSDI official patch #14: 
SUMMARY:
    Here is a patch for a kernel hang that can be provoked with a write
    or send of a negative amount.  The talk program is capable of exercising
    this bug.  This patch also includes a fix for a bug that caused data
    to be delivered to TCP in smaller chunks than desired, and which caused
    TCP to send a short packet when starting up.  Finally, there is a bug
    fix for MSG_PEEK with an oobmark pending.

cgd 13ca4d98c7 it's correct to return EACCES if FS is mounted MNT_NOEXEC. 1993-10-26 01:42:56 +00:00
cgd c7582cbd4f use copyinstr rather than strcpy to copy in the saved shell-script 
name from userland.  From Markus Wild, mw@lamp
 1993-10-26 00:32:29 +00:00
cgd ce7108c729 slightly clean up ws's original patch to this file for the sense 
of wait vs. nowait.  this patch from torek.

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.

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.

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.

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>:

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.

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

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)

the latter of which is a jolitz invention.

cgd 57ee917973 allocate out of kmem_map, not buffer_map. buffer_map is for

andrew 3e701a1438 * ansifications 
* Yuval Yarom's socket recv(2) fixes - access rights problems (see also
  uipc_socket.c).
 1993-06-27 06:08:40 +00:00
andrew d46fb2c3fb * ansifications 
* Yuval Yarom's socket recv(2) fixes, to prevent incorrect blocking and
  lack thereof with recv(2) and MSG_WAITALL.  Fixes a sbdrop() panic during
  some MSG_WAITALL recv(2) sleeps.  Access rights fix (also in
  uipc_syscalls.c) too.  A test program which shows these problems is
  available.

andrew 6535028529 * ansifications 
* fixed the arguments given to the line discipline l_open function in
  ptsopen()

andrew 4d08b29158 * ansifications 
* question about whether the "tp->t_state |= TS_ISOPEN" in ttyopen() should
  be shifted to the end of the block in which it appears.
 1993-06-27 06:06:14 +00:00
andrew f74843ee98 * ansifications 
* cleaned up hardclock() to avoid checking "p" multiple times, and avoid a
  gcc2 possible-use-before-initialisation warning.
* changed softclock() timeout callback functions to be of type timeout_t -
  a pointer to a void fn(int).  No-one was using the second, tick, argument
  that was being passed to these callbacks - it is much cleaner to drop the
  thing entirely, rather than add a whole heap of casts of dubious
  correctness to calls to timeout(), etc.  The old style is kept in an
  #ifdef, for future reference.
 1993-06-27 06:05:32 +00:00
andrew 0e6cb953ea ANSIfications - removed all implicit function return types and argument 
definitions.  Ensured that all files include "systm.h" to gain access to
general prototypes.  Casts where necessary.

cgd 24fe3e4563 fixed bug where extra spaces at the end of a shell name would 
cause shell scripts to be executed incorrectly.  shells would
receive an *empty* arg for name of script, open it, the kernel
would say "oh, that's ." or something similar, and the results
would be interesting...  found, diagnosed, and killed by me.
