src/sys/dev/dpt/dpt_control.c, branch release/4.0.0_cvs

This commit was manufactured by cvs2svn to create tag

'RELENG_4_0_0_RELEASE'.

This commit was manufactured to restore the state of the 4.0-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

Remove five now unused fields from struct cdevsw. They should never

1999-09-25T18:24:47+00:00

have been there in the first place.  A GENERIC kernel shrinks almost 1k.

Add a slightly different safetybelt under nostop for tty drivers.

Add some missing FreeBSD tags

$Id$ -> $FreeBSD$

Simplify cdevsw registration.

1999-05-31T11:29:30+00:00

The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

I4b and vinum not changed.  Patches emailed to authors.  LINT
probably broken until they catch up.

This commit should be a extensive NO-OP:

1999-05-30T16:53:49+00:00

        Reformat and initialize correctly all "struct cdevsw".

        Initialize the d_maj and d_bmaj fields.

        The d_reset field was not removed, although it is never used.

I used a program to do most of this, so all the files now use the
same consistent format.  Please keep it that way.

Vinum and i4b not modified, patches emailed to respective authors.

I'm told by the PR author that this page_size increment was in

1999-05-13T05:24:53+00:00

the wrong place; back it out.

During probe, the page lockdown code in dpt_control.c does some

1999-05-11T11:03:18+00:00

bad math: it does not handle page-boundary conditions, and will not
end up mapping all of the requested addresses.  This will cause a panic:
page fault during probe on some systems.  I have a machine that will
panic every time (when using the dpt driver) on kernel probe when there
are 5 drives installed.  When there are 4 drives, it is fine.
Fix is to always allocate/deallocate an extra page.
There is also a bonus splx() fix on an early error return.

Examine all occurrences of sprintf(), strcat(), and str[n]cpy()

1998-12-04T22:54:57+00:00

for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.
