4591d9bb7e UFS_UPDATE() takes a boolean `waitfor' arg, so don't pass it the value
MNT_WAIT when we mean boolean `true' or check for that value not being
passed.  There was no problem in practice because MNT_WAIT had the

2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
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.

d2165c2f7d Fixed bloatage of `struct inode'. We used 5 "spare" fields for ext2fs,
but when i_effnlink was added to support soft updates, there was only
room for 4 spares.  The number of spares was not reduced, so the inode
size became 260 (on i386's), or 512 after rounding up by malloc().
Use one spare field in `struct dinode' instead of the 5th spare field
in the inode and reduced to 4 spares in the inode so that the size is
256 again.

Changed the types of the spares in the inode from int to u_int32_t
so that the inode size has more chance of being <= 256 under other
arches, and downdated ext2fs to match (it was broken to use ints
before rev.1.1).

8f359bc68c Quick fix for not being able to sync all the buffers in boot() if
an ext2fs file system is mounted.  The soft update changes added
a check for B_DELWRI buffers.  This exposed the complete brokenness
of the previous quick fix for failing syncs (PR 3571, committed on
1997/08/04).  Use a new buffer flag B_DIRTY and don't abuse B_DELWRI.
B_DIRTY buffers are still written too late, as broken in the previous
fix.  This is fairly harmless, because B_DIRTY is only used for
bitmap buffers and fsck.ext2 can fix up the bitmaps perfectly.

Fixed a race in ULCK_BUF() (bremfree() was outside of the splbio()
section).

syncs weren't optimized properly (they probably still aren't, but are bug

ext2fs is too broken to mount read-write (it apparently doesn't clear
indirect blocks).

a094db128f Fixed clean flag handling:
Fixes for bugs not shared with ffs:
- don't mount unclean filesystems rw unless forced to.
- accept EXT2_ERROR_FS (treat it like !EXT2_VALID_FS).  We still don't set
  this or honour the maximal mount count.
- don't attempt to print the name of the mount point when mounting an
  unclean file system, since the name of the previous mount point is
  unknown and the name of the current mount point is still "".

Fixes for bugs shared with ffs until recently:
- don't set the clean flag on unmount of an initially-unclean filesystem
  that was (forcibly) mounted rw.
- set the clean flag on rw -> ro update of a mounted initially-clean
  filesystem.
- fixed some style bugs (mostly long lines).

The fixes are slightly simpler than for ffs, because the relevant on-disk
state is not a simple boolean variable, and the superblock has a core-only
extension.

1874ef935c Quick fix for breakage of read clustering on non-IDE drives. Read
clustering is obsolescent technology so hardly anyone noticed.  On
a DORS 32160 SCSI drive with 4 tags, read clustering makes very
little difference even for huge sequential reads.  However, on a
ZIP SCSI drive with 0 tags, the minimum overhead per block is about
40 msec, so very large clusters must be used to get anywhere near
the maximum transfer rate.  Using clusters consisting of 1 8K block
reduces the transfer rate to about 250K/sec.  Under msdosfs, missing
read clustering is normal and a cluster size of 1 512 byte block
reduces the transfer rate to about 25K/sec.

3055187290 Sync timestamp changes for inodes of special files to disk as late
as possible (when the inode is reclaimed).  Temporarily only do
this if option UFS_LAZYMOD configured and softupdates aren't enabled.
UFS_LAZYMOD is intentionally left out of /sys/conf/options.

This is mainly to avoid almost useless disk i/o on battery powered
machines.  It's silly to write to disk (on the next sync or when the
inode becomes inactive) just because someone hit a key or something
wrote to the screen or /dev/null.

add4ae9324 Fixed (?) races in mark_buffer_dirty(). We abuse the buffer cache
by hacking on locked buffers without getblk()ing them, and we didn't
even use splbio() to prevent biodone() changing the buffer underneath
use when a write completes.  I think there was no problem in practice
on i386's because the operations on b_flags and numdirtybufs happen to
be atomic.  We still depend on biodone()'s operations on b_flags not
interfering with ours.  I think there is only interference for B_ERROR,
and this is harmless because errors for async writes are ignored anyway.

Don't use mark_buffer_dirty() except for superblock-related metadata.
It was used in just one case where ordinary BSD buffering is more
natural.

9b7a8fb7d8 Removed unused function ll_w_block(). It has always had races due

---------
Make callers of namei() responsible for releasing references or locks
instead of having the underlying filesystems do it.  This eliminates
redundancy in all terminal filesystems and makes it possible for stacked
transport layers such as umapfs or nullfs to operate correctly.

Quality testing was done with testvn, and lat_fs from the lmbench suite.

Some NFS client testing courtesy of Patrik Kudo.

vop_mknod and vop_symlink still release the returned vpp.  vop_rename
still releases 4 vnode arguments before it returns.  These remaining cases
will be corrected in the next set of patches.

79cc756d8b As described by the submitter:
Reverse the VFS_VRELE patch.  Reference counting of vnodes does not need
to be done per-fs.  I noticed this while fixing vfs layering violations.
Doing reference counting in generic code is also the preference cited by
John Heidemann in recent discussions with him.

The implementation of alternative vnode management per-fs is still a valid
requirement for some filesystems but will be revisited sometime later,
most likely using a different framework.

227ee8a188 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

the same.

34bdbbd0de The intent is to get rid of WILLRELE in vnode_if.src by making
a complement to all ops that return a vpp, VFS_VRELE.  This is
initially only for file systems that implement the following ops
that do a WILLRELE:

	vop_create, vop_whiteout, vop_mknod, vop_remove, vop_link,
	vop_rename, vop_mkdir, vop_rmdir, vop_symlink

This is initial DNA that doesn't do anything yet.  VFS_VRELE is
implemented but not called.

A default vfs_vrele was created for fs implementations that use the
standard vnode management routines.

VFS_VRELE implementations were made for the following file systems:

Standard (vfs_vrele)
	ffs mfs nfs msdosfs devfs ext2fs

Custom
	union umapfs

Just EOPNOTSUPP
	fdesc procfs kernfs portal cd9660

These implementations may change as VOP changes are implemented.

In the next phase, in the vop implementations calls to vrele and the vrele
part of vput will be moved to the top layer vfs_vnops and made visible
to all layers.  vput will be replaced by unlock in these cases.  Unlocking
will still be done in the per fs layer but the refcount decrement will be
triggered at the top because it doesn't hurt to hold a vnode reference a
little longer.  This will have minimal impact on the structure of the
existing code.

This will only be done for vnode arguments that are released by the various
fs vop implementations.

Wider use of VFS_VRELE will likely require restructuring of the code.

Ever since I first say the way the mount flags were used I've hated the
fact that modes, and events, internal and exported, and short-term
and long term flags are all thrown together. Finally it's annoyed me enough..
This patch to the entire FreeBSD tree adds a second mount flag word
to the mount struct. it is not exported to userspace. I have moved
some of the non exported flags over to this word. this means that we now
have 8 free bits in the mount flags. There are another two that might
well move over, but which I'm not sure about.
The only user visible change would have been in pstat -v, except
that davidg has disabled it anyhow.
I'd still like to move the state flags and the 'command' flags
apart from each other.. e.g. MNT_FORCE really doesn't have the
same semantics as MNT_RDONLY, but that's left  for another day.

   control clustered I/O from userland.
2. When foofs_mount mounts block device, foofs_mount checks D_CLUSTERR
   and D_CLUSTERW bits of the d_flags member in the block device switch
   table.  If D_NOCLUSTERR / D_NOCLUSTERW are set, MNT_NOCLUSTERR /
   MNT_NOCLUSTERW bits will be set.  In this case, MNT_NOCLUSTERR and
   MNT_NOCLUSTERW cannot be cleared from userland.

0fa2443f0e Uncut&paste cache_lookup().
This unifies several times in theory indentical 50 lines of code.

The filesystems have a new method: vop_cachedlookup, which is the
meat of the lookup, and use vfs_cache_lookup() for their vop_lookup
method.  vfs_cache_lookup() will check the namecache and pass on
to the vop_cachedlookup method in case of a miss.

It's still the task of the individual filesystems to populate the
namecache with cache_enter().

Filesystems that do not use the namecache will just provide the
vop_lookup method as usual.

The vfs_bio code in general had little ability to handle buffer resource
management, and now it does.  Also, there are a lot more knobs for tuning the
vfs_bio code now.  The knobs came free because of the need that there
always be some immediately available buffers (non-delayed or locked) for
use.  Note that the buffer cache code is much less likely to get bogged
down with lots of delayed writes, even more so than before.

9081eec1fb Make the necessary changes so that an ELF kernel can be built. I
have successfully built, booted, and run a number of different ELF
kernel configurations, including GENERIC.  LINT also builds and
links cleanly, though I have not tried to boot it.

The impact on developers is virtually nil, except for two things.
All linker sets that might possibly be present in the kernel must be
listed in "sys/i386/i386/setdefs.h".  And all C symbols that are
also referenced from assembly language code must be listed in
"sys/i386/include/asnames.h".  It so happens that failure to do
these things will have no impact on the a.out kernel.  But it will
break the build of the ELF kernel.

The ELF bootloader works, but it is not ready to commit quite yet.

87241caa43 This commit is the embodiment of some VFS read clustering improvements.
Firstly, now our read-ahead clustering is on a file descriptor basis and not
on a per-vnode basis.  This will allow multiple processes reading the
same file to take advantage of read-ahead clustering.  Secondly, there
previously was a problem with large reads still using the ramp-up
algorithm.  Of course, that was bogus, and now we read the entire
"chunk" off of the disk in one operation.   The read-ahead clustering
algorithm should use less CPU than the previous also (I hope :-)).

f886b4857a Removed gratuitous differences between ext2_readwrite.c and ufs_readwrite.c.
This fixes several bugs and one missing feature:
- cluster_read() was needlessly used for reading files of size exactly 1
  block.
- EFAULT errors for read didn't terminate the loop.  This was probably
  harmless.
- IO_VMIO handling was missing near line 275.  I don't know what this does.
- B_CLUSTEROK was only set if (doclusterwrite) nead line 293.  This was
  harmless, if only because another bug prevents doclusterwrite from being

  ioctl headers.  Header spam currently increases kernel build
  times by 10-20%.  There are more than 30000 #includes (not counting

- include <sys/types.h> if and only it is necessary to make the header

87f6c6625d Pass 3 of the great devsw changes
most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)

If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)

pass 4 will be to make the devsw tables of type (cdevsw * )
rather than (cdevsw)
seems to work here..

my next trick will be to define cdevsw[] and bdevsw[]

Each of these drivers has a SYSINIT linker set entry
that comes in very early.. and asks teh driver to add it's own
entry to the two devsw[] tables.

some slight reworking of the commits from yesterday (added the SYSINIT
stuff and some usually wrong but token DEVFS entries to all these
devices.

BTW does anyone know where the 'ata' entries in conf.c actually reside?
seems we don't actually have a 'ataopen() etc...

If you want to add a new device in conf.c
please  make sure I know
so I can keep it up to date too..

as before, this is all dependent on #if defined(JREMOD)

f57e65478d Introduced a type `vop_t' for vnode operation functions and used
it 1138 times (:-() in casts and a few more times in declarations.
This change is null for the i386.

The type has to be `typedef int vop_t(void *)' and not `typedef
int vop_t()' because `gcc -Wstrict-prototypes' warns about the
latter.  Since vnode op functions are called with args of different
(struct pointer) types, neither of these function types is any use
for type checking of the arg, so it would be preferable not to use
the complete function type, especially since using the complete
type requires adding 1138 casts to avoid compiler warnings and
another 40+ casts to reverse the function pointer conversions before
calling the functions.

9fa18570a2 Obtained from: partly from ancient patches of mine via 1.1.5
Introduce TS_CONNECTED and TS_ZOMBIE states.  TS_CONNECTED is set
while a connection is established.  It is set while (TS_CARR_ON or
CLOCAL is set) and TS_ZOMBIE is clear.  TS_ZOMBIE is set for on to
off transitions of TS_CARR_ON that occur when CLOCAL is clear and
is cleared for off to on transitions of CLOCAL.  I/o can only occur
while TS_CONNECTED is set.  TS_ZOMBIE prevents further i/o.

Split the input-event sleep address TSA_CARR_ON(tp) into TSA_CARR_ON(tp)
and TSA_HUP_OR_INPUT(tp).  The former address is now used only for
off to on carrier transitions and equivalent CLOCAL transitions.
The latter is used for all input events, all carrier transitions
and certain CLOCAL transitions.  There are some harmless extra
wakeups for rare connection- related events.  Previously there were
too many extra wakeups for non-rare input events.

Drivers now call l_modem() instead of setting TS_CARR_ON directly
to handle even the initial off to on transition of carrier.  They
should always have done this.  l_modem() now handles TS_CONNECTED
and TS_ZOMBIE as well as TS_CARR_ON.

gnu/isdn/iitty.c:
Set TS_CONNECTED for first open ourself to go with bogusly setting
CLOCAL.

i386/isa/syscons.c, i386/isa/pcvt/pcvt_drv.c:
We fake carrier, so don't also fake CLOCAL.

kern/tty.c:
Testing TS_CONNECTED instead of TS_CARR_ON fixes TIOCCONS forgetting to
test CLOCAL.  TS_ISOPEN was tested instead, but that broke when we disabled
the clearing of TS_ISOPEN for certain transitions of CLOCAL.

Testing TS_CONNECTED fixes ttyselect() returning false success for output
to devices in state !TS_CARR_ON && !CLOCAL.

Optimize the other selwakeup() call (this is not related to the other
changes).

kern/tty_pty.c:
ptcopen() can be declared in traditional C now that dev_t isn't short.

Give names to the magic tty i/o sleep addresses and use them.  This makes
it easier to remember what the addresses are for and to keep them unique.

a16721a13a Move the inline code for waking up writers to a new function
ttwwakeup().  The conditions for doing the wakeup will soon become
more complicated and I don't want them duplicated in all drivers.

It's probably not worth making ttwwakeup() a macro or an inline
function.  The cost of the function call is relatively small when
there is a process to wake up.  There is usually a process to wake
up for large writes and the system call overhead dwarfs the function
call overhead for small writes.

Nuke `symbolic sleep message strings'.  Use unique literal messages so that
`ps l' shows unambiguously where processes are sleeping.

0d1de831ea Obtained from: partly from an ancient patch of mine via 1.1.5
Temporarily nuke TS_WOPEN.  It was only used for the obscure MDMBUF
flow control option in the kernel and for informational purposes
in `pstat -t'.  The latter worked properly only for ptys.  In
general there may be multiple processes sleeping in open() and
multiple processes that successfully opened the tty by opening it
in O_NONBLOCK mode or during a window when CLOCAL was set.  tty.c
doesn't have enough information to maintain the flag but always
cleared it in ttyopen().

TS_WOPEN should be restored someday just so that `pstat -t' can
display it (MDMBUF is already fixed).  Fixing it requires counting
of processes sleeping in open() in too many serial drivers.

3cddb2a3e2 John Aycock's BSD copyrighted sequencer assembler and sequencer code. This
is identical to the older version, just the copyright has changed.  Many
thanks go to Dean Gehnert of the Linux camp who went the extra mile to make
this happen.

Other changes:

Update assembler man page to include the -v and -D options

Merge in Dean's latest changes to the assembler

Have the sequencer do a MSG_REJECT when the negotiated syncronous rate
is lower than the adapter supports.  This forces asyncronous mode which
is faster at these rates anyway.

This code will be moved shortly to the non-gpld portion of the tree.

cc865dd008 Off by one error in -MSG-START+0 was just Justin being tired -- revert to
old value.

Remove unnecessary check for active messages in setup SCB.  This same test
would also jump to p_mesgin_done which would "ACK" an extra time possibly
confusing the target.

Tell the kernel driver whenever we send an ABORT_TAG message.

5743c01c3f Major overhaul of the aic7xxx driver:
- Report valid residual byte counts.  We actually pause the sequencer
	  when the residual is non-zero.  I thought about using DMA to do this,
	  bus sequencer program space is tight.

	- Fix embarassing off by one error in the computation of a 2's
	  compliment variable.  This was most likely the cause of the
	  many problems reported with the tagged queuing code.

	- Handle "MAX_SYNC" as a special case (ie we are the ones starting
	  the sync negotiation sequence).  This was done so that the target
	  scratch area can be initialed to 0 offset (asyncronous transfers)
	  safely.  The initialization to 0 (was 15) is necessary since in
	  some cases a Wide negotiation could run into problems if SCSIRATE
	  was set wrong and we went into data(in/out).

	- Trim the DMA routines a little by using some procedures.  Net
	  effect is more functionality with 3 less instructions after this
	  update.

	- Toggle the WIDEODD bit of the DFCNTRL whenever this is not the
	  last SG block.  It has no effect in the 8bit bus configuration,
	  but in the Wide configuration ensures that the overlap byte is
	  held in the SCSI block if the transfer is odd so it will end
	  up in the next SG (the correct behavior).

(b) add a function callback vector to tty drivers that will return a pointer
    to a valid tty structure based upon a dev_t
(c) make syscons structures the same size whether or not APM is enabled so
    utilities don't crash if NAPM changes (and make the damn kernel compile!)
