cgd 491d6b4b9d fix problem where exec would lose on shell scripts with symlinks in 
their names.  fix from "James W. Dolter" <jdolter@sawtooth.eecs.umich.edu>.
test script:

#!/bin/csh
mkdir /tmp/foodir
cat > /tmp/foodir/testscript <<EOF
#!/bin/sh
echo "Executing script \$1"
EOF
chmod 755 /tmp/foodir/testscript
(cd /tmp ; ln -s foodir foosym)
echo "Trying full path (w/o symlink) to /tmp/foodir/testscript"
/tmp/foodir/testscript "with out symlink"
echo "Trying full path (w/ symlink) to /tmp/foosym/testscript"
/tmp/foosym/testscript "with symlink"
echo "End of Test"

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 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.

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.

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

cgd eb4c4de385 replace exec. 
new one based on one by Wolfgang Solfrank, but majorly hacked

deraadt ada4945e6b patches to make kernel malloc() retryable. from <MDICKSON@CSI.compuserve.com> 1993-05-27 14:34:29 +00:00
deraadt b671aede02 slight functionality change to make the rbpack() and 
rbunpack() code that I wrote before work cleaner. Many old drivers
call nnn = q_to_b(queue, buf, len), where nnn gets set to len.
for those who are porting:
	q_to_b(queue, buf, len) --> rbunpack(queue, buf, len)
	b_to_q(buf, queue, len) --> rbpack(buf, queue, len)
ie. they are essentialy drop in replacements now.

 1993-04-09 19:37:49 +00:00
cgd a128c34f9c From: Guido van Rooij <guido@gvr.win.tue.nl> 
when mmapping a file, permissions are checked as it should be. When
mprotect()-ing the address range afterwards, no protection was checked
regarding the protection of the file originally opened. So
when you open /usr/bin/su RDONLY and SHARED you could afterwards change
the mmapped region to READ|WRITE. This gave the possibility to obtain
root privs obviously.
 1993-04-09 17:16:30 +00:00

deraadt 6efd5159e0 getdomainname fix. had to declare get/setdomainname() implicitly extern. 1993-04-02 20:38:22 +00:00
cgd b02974b037 Jay Fenlason <hack@datacube.com>: 
1: the fi_readers and fi_writers fields of the fifoinfo structure were not
being initialized to 0.  This caused the driver to not sleep the first
process to open the fifo--it thought there was already another process to
talk to (most of the time.)

2: fifo_open() was calling tsleep() without unlocking the inode of the fifo
file.  This caused *any* subsequent access to the file (even an ls (!)) to
hang forever.  Note that this bug was usually masked by bug #1 above.
 1993-04-02 20:19:48 +00:00
deraadt 355265a866 added: the entire domainanme set. domainmame(1), domainname(2), and a spiffy
