2cd253ad0f Replace the preprocessor variable names BDEV_MAJOR and CDEV_MAJOR with
VINUM_BDEV_MAJOR and VINUM_CDEV_MAJOR respectively.

Set DRIVE_MAXACTIVE and VINUM_MAXACTIVE to 30000, effectively
disabling the request limitation code.  This code was added as an
attempt to escape from a bug which seems to have gone away, and it's
very likely I'll remove the code Real Soon Now, but I don't want to do
it just yet.

struct drive: Remove references to vnode pointers, including debug
output.  Vinum now talks directly to the device driver.  Instead, add
a dev_t.

enum plexorg: Add an instance for RAID-4.

Change checks for striped or RAID-5 plexes to a macro 'isstriped',
which now also includes RAID-4.

Change checks for RAID-5 plexes to a macro 'isparity', which now also
includes RAID-4.

e862b9e36a open_drive: open drives directly rather than going via namei and
vn_open.  This is necessary in order to be able to open drives before
the root file system is mounted.  This also involves restructuring the
drive struct, which no longer contains a vnode pointer.  Instead,
open_drive sets an open flag.  It's a horrible kludge, and I'll gladly
borrow a Danish axe and hack it in little pieces when devfs comes.

read_drive, write_drive, drive_io_done: Replace with driveio.  The
function names are now macros.

read_drive and write_drive existed in the first place.

e435b3206e Add support for RAID-4, even though it is inferior in almost every way
to RAID-5.  peter claims that it might be faster for sequential

e50342e665 Yesterday I had to fix a badly broken disk, and found that fsck kept dying:
DIR I=64512 CONNECTED. PARENT WAS I=4032
  fsck: cannot find inode 995904

fsdb found the inodes with no problem:

  fsdb (inum: 64512)> inode 995904
  current inode: directory
  I=995904 MODE=40777 SIZE=512
        MTIME=Feb 14 15:27:07 2000 [0 nsec]
        CTIME=Feb 14 15:27:07 2000 [0 nsec]

  Direct blocks: 8094568 0 0 0 0 0 0 0 0 0 0 0
  Indirect blocks:  0 0 0

The problem turns out to be a program logic error in fsck.  It stores
directory inodes internally in hash lists, using the number of
directories to form the hash key:

        inpp = &inphead[inumber % numdirs];

Elsewhere, however, it increments numdirs when it finds unattached
directories.  I've made the following fix, which solved the problem in
the case in hand.

b3f1e629e9 This fixes a problem where the SIOCGIFCONF ioctl goes wrong. This
is triggered when qmail is used with INET6 enabled.  The bug
manifests itself in that the space variable can become negative
and that in the comparison in the guards of the 2 loops, this was
not noticed because sizeof() returns an unsigned and thus the signed
variable gets promoted to unsigned. I decided not to make space
unsigned because I think we should guard against this from happening.
Thus panic() in case space becomes negative.

6b5c2dd6a1 Fix a serious bug in syslogd regarding the handling of pipes. The bug
would cause syslogd to eventually kill innocent processes in the
system over time (note: not `could' but `would').  Many thanks to my
colleague Mirko for digging into the kernel structures and providing
me with the debugging framework to find out about the nature of this
bug (and to isolate that syslogd was the culprit) in a rather large
set of distributed machines at client sites where this happened
occasionally.

Whenever a child process was no longer responsive, or when syslogd
receives a SIGHUP so it closes all its logging file descriptors, for
any descriptor that refers to a pipe syslogd enters the data about the
old logging child process into a `dead queue', where it is being
removed from (and the status of the dead kitten being fetched) upon
receipt of a SIGCHLD.  However, there's a high probability that the
SIGCHLD already arrives before the child's data are actually entered
into the dead queue inside the SIGHUP handler, so the SIGCHLD handler
has nothing to fetch and remove and simply continues.  Whenever this
happens, the process'es data remain on the dead queue forever, and
since domark() tried to get rid of totally unresponsive children by
first sending a SIGTERM and later a SIGKILL, it was only a matter of
time until the system had recycled enough PIDs so an innocent process
got shot to death.

Fix the race by masking SIGHUP and SIGCHLD from both handlers mutually.

Add additional bandaids ``just in case'', i. e. don't enter a process
into the dead queue if we can't signal it (this should only happen in
case it is already dead by that time so we can fetch the status
immediately instead of deferring this to the SIGCHLD handler); for the
kill(2) inside domark(), check for an error status (/* Can't happen */
:) and remove it from the dead queue in this case (which if it would
have been there in the first place would have reduced the problem to a
statistically minimal likelihood so i certainly would never have
noticed the bug at all :).

Mirko also reviewed the fix in priciple (mutual blocking of both
signals inside the handlers), but not the actual code.
