cgd(4): Omit technically-correct-but-broken adiantum dependency again.

It is true that cgd_crypto.c depends on sys/crypto/adiantum now, and
transitively on sys/crypto/aes.

However, there's a problem with the cgd module having a formal
(transitive) module dependency on the aes module.

Yesterday I thought the problem with this was that fpu_kern_enter was
artificially restricted while cold -- to detect, and noisily crash
on, reentrance, it raises the IPL to IPL_VM, asserts that the IPL is
not _higher_ (so it can't be re-entered by an IPL_SCHED or IPL_HIGH
interrupt), and asserts that it's not currently in use on the current
CPU.

Early at boot, the IPL is at IPL_HIGH, and no interrupts are possible
anyway, so the assertions tripped for artificial reasons, which I
fixed in:

https://mail-index.netbsd.org/source-changes/2022/04/01/msg137840.html

However, I had forgotten that there's a deeper problem for the cgd
module dependency on aes.  The ordering of events is:

1. Initialize builtin MODULE_CLASS_DRIVER modules -- including cgd.

2. Run configure -- including detecting CPUs, which on aarch64 is
   where the decision of which AES (and ChaCha) implementation to use
   based on supported CPU features.

3. Initialize builtin MODULE_CLASS_MISC modules -- including aes,
   _if_ there are no driver-class modules that depend on it.

There's a tangle of ordering dependencies here:

- MODULE_CLASS_DRIVER modules providing _autoconf_ drivers generally
  have to be initialized _before_ configure, because you need the
  driver to be initialized before configure can attach its devices.

- configure must run _before_ aes is initialized because the decision
  of which AES implementation to choose depends on CPU features
  detected in configure, and the prospect of dynamically changing the
  AES implementation is too painful to contemplate (it may change the
  key schedule, so it would invalidate any existing key schedules
  precomputed by callers like uvm_swap or configured cgd devices,
  which raises a host of painful concurrency issues to invalidate
  these cached key schedules on all CPUs in all subsystems using
  them).

- cgd doesn't figure into the configure stage of autoconf, but it
  nevertheless has to be MODULE_CLASS_DRIVER because specfs autoloads
  MODULE_CLASS_DRIVER modules in case they provide _devsw_ drivers
  (i.e., /dev nodes), as cgd does.  And we don't have a mechanism for
  identifying `autoconf driver modules' separately from `devsw driver
  modules' because some modules provide both and each module can have
  only one class.

For now, this is breaking boot on several tier I architectures so
let's nix the cgd->adiantum->aes module dependency as a stop-gap
measure.

Create a loaable adiantum module, and make cgd require it.

This enablees use of a loadable cgd module, rather thtan requiring
it to be built-in.

cgd(4): Remove recently added dependency on adiantum.

While this dependency is technically correct, it triggers a problem
with module initialization for builtin modules that manifests as an
instant crash on boot for x86 (and likely arm) kernels, and that
problem is not trivial to solve immediately.  See the top of
sys/crypto/aes/aes_impl.c for a summary of the problem and why it's
tricky.

So as a stop-gap measure, we'll remove this dependency for now; we
can reinstate it later once the underlying problem with module
initialization order is resolved.

(actually first reported, to my knowledge, by pgoyette@, but this
line tells syzkaller that we fixed the problem)

For device modules that provide both auto-config and /dev/xxx
interfaces, make sure that initialization and destruction
follow the proper sequence.  This is triggered by the recent
changes to the devsw stuff; per riastradh@ the required call
sequence is:

	devsw_attach()
	config_init_component() or config_cf*_attach()
	...
	config_fini_component() or config_cf*_detach()
	devsw_detach()

While here, add a few missing calls to some of the detach
routines.

Testing of these changes has been limited to:
	1. compile without build break
	2. no related test failures from atf
	3. modload/modunload work as well as
	   before.

No functional device testing done, since I don't have any
of these devices.  Let me know of any damage I might cause
here!

XXX Some of the modules affected by this commit are already
XXX broken;  see kern/56772.  This commit does not break
any additional modules (as far as I know).

cgd(4): Fix criterion for detach when wedgies are held.

The somewhat confusingly named DK_BUSY(dksc, pmask) answers the
following question:

        Suppose I hold either the character or the block device (but
        not both) of all of the partitions in pmask.  Is anyone else
        using the disk, rendering it unsafe to detach?

This is useful for ioctls like CGDIOCCLR and VNDIOCCLR, which must be
issued on open file descriptors for the disk, so the question cannot
simply be answered by testing whether dk_openmask != 0.
Instead, DK_BUSY breaks the question into the following criteria:

        1. Are there any _other_ partitions than those in pmask open
           at all?  If so, it must be someone else, since I only hold
           partitions in pmask -- hence the disk is busy.
        2. Are any of the partitions in pmask open _both_ as a block
           device _and_ as a character device?  If so, it must be
           someone else, since I only hold _either_ the character
           _or_ the block device open but not both -- hence the disk
           is busy.

When config_detach_all runs at shutdown time, it tries to detach
cgd(4), which has DVF_DETACH_SHUTDOWN; this is important so we submit
queued writes to the underlying disk and wait for them to complete
with dk_drain.

If cgd(4) has any dk wedges with file systems mounted still
configured on it, it isn't ready to detach yet.  But asking
DK_BUSY(dksc, 1 << RAW_PART) returns false, because the dk wedges
only hold RAW_PART open as a block device -- so if nobody has
RAW_PART open as a character device, or any other partitions open,
cgd_detach blithely goes on its way to forcibly detach the wedges.

Instead, ask DK_BUSY(dksc, 0), because the caller -- cgd_detach
issued by config_detach_all -- does not, in fact, hold any partitions
open, so it doesn't need to work around them like ioctl(CGDIOCCLR)
does.  Fixes hang in zfs on dk on cgd during shutdown (and probably
also zfs on cgd without any intervening dk but I haven't tested).

(This change might have the side effect that `drvctl -d cgdN' doesn't
work, but I don't care.)

Add a flag to dk_dump for virtual disk devices.

If a disk is backed by a physical medium other than itself, such as
cgd(4), then it passes DK_DUMP_RECURSIVE to disable the recursion
detection for dk_dump.

If, however, a device represents a physical medium on its own, such
as wd(4), then it passes 0 instead.

With this, I can now dump to dk on cgd on dk on wd.

New ioctl DIOCGSECTORALIGN returns sector alignment parameters.

struct disk_sectoralign {
        /* First aligned sector number.  */
        uint32_t dsa_firstaligned;
        /* Number of sectors per aligned unit.  */
        uint32_t dsa_alignment;
};

- Teach wd(4) to get it from ATA.
- Teach cgd(4) to pass it through from the underlying disk.
- Teach dk(4) to pass it through with adjustments.
- Teach zpool (zfs) to take advantage of it.
  => XXX zpool doesn't seem to understand when the vdev's starting
     sector is misaligned.

Missing:
- ccd(4) and raidframe(4) support -- these should support _using_
  DIOCGSECTORALIGN to decide where to start putting ccd or raid
  stripes on disk, and these should perhaps _implement_
  DIOCGSECTORALIGN by reporting the stripe/interleave factor.
- sd(4) support -- I don't know any obvious way to get it from SCSI,
  but if any SCSI wizards know better than I, please feel free to
  teach sd(4) about it!
- any ld(4) attachments -- might be worth teaching the ld drivers for
  nvme and various raid controllers to get the aligned sector size

There's some duplicate logic here for now.  I'm doing it this way,
rather than gathering the logic into a new disklabel_sectoralign
function or something, so that this change is limited to adding a new
ioctl, without any new kernel symbols, in order to make it easy to
pull up to netbsd-9 without worrying about the module ABI.

Make getdiskinfo() compatible with a DIOCGWEDGEINFO.

dkw_parent is defined to hold the disk name as used by disk_find(), not
a partition (i.e. no partition letter appended).

Use utility functions to handle disk geometry.

Add a flag to dk_dump for virtual disk devices.

If a disk is backed by a physical medium other than itself, such as
cgd(4), then it passes DK_DUMP_RECURSIVE to disable the recursion
detection for dk_dump.

If, however, a device represents a physical medium on its own, such
as wd(4), then it passes 0 instead.

With this, I can now dump to dk on cgd on dk on wd.

Introduce config_detach_release() which does all the work from the
former config_detach().  Now, config_detach() simply acquires a
reference to the device, which config_detach_release() can release!

This is needed because some drivers call config_detach() with a
reference, while other drivers have not been updated to use the
localcount reference mechanism.  So we provide a shim to make
everyone equal.

don't return without calling device_release(), as any subsequent attempt to

When initializing the rump cgd component, use the correct driver name
(as found in the devsw_conv[] table).  This will get us the "official"
major numbers for the cgd device.

After creating the rump file-space nodes for /dev/cgd* we then need to
detach the [bc]devsw's because normal module initialization will do its
own attachment, and we don't want that to fail.

While here, since we're doing the devsw_attach() twice, share the
results from the first call rather than starting from scratch.

First pass at updating the cgd(4) driver for use with localcount(9)
ref-counts.

So far all I've done is to manage the ref-counts.  This will defer
removal of the driver from the devsw tables and/or the autoconf tree
while anyone has a reference to any of the device's critical data
(mostly, the softc or the device_t).  Note that these ref-counts will
only defer the removal;  once the references are released, the removal
will proceed.

On-going work is needed to identify potentially blocking operations,
and to deny any removals if such operations are in-flight.  We really
shouldn't be waiting (possibly indefinitely) for these operations to
complete, especially since removals could be attempted by the module(9)
subsystem while holding the kernel_config lock.

This increase complexity only marginally: the underlying drivers have
to do the while() loop themselves, but this can now be done properly with
bufq_peek()/bufq_get(), removing the buffer from the queue at the right time.
This handle both the recursion and reordering issues (the reordering
issue is described here:
https://mail-index.netbsd.org/tech-kern/2014/05/19/msg017089.html
the recursion isssue is PR #25240).

Difference with the patch posted to tech-kern@: KASSERT() that the
buffer we remove with bufq_get() is the same as the one we bufq_peek()'d
just before.
Hopefully this will allow more disk drivers to use dksubr.c

Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

the drvctl framework.  And call this new functionality from cgd(4),
the consumer of dksubr.c.  We do this to allow gpt(8) to be able
to label cgd(4) disks.  We also add in some DIOCGSECTORSIZE logic
and we ensure that the WEDGE ioctls are not called on either
uninitialised disks or disks which have not been opened for write
access.

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

Introduce struct pathbuf. This is an abstraction to hold a pathname
and the metadata required to interpret it. Callers of namei must now
create a pathbuf and pass it to NDINIT (instead of a string and a
uio_seg), then destroy the pathbuf after the namei session is
complete.

Update all namei call sites accordingly. Add a pathbuf(9) man page and
update namei(9).

The pathbuf interface also now appears in a couple of related
additional places that were passing string/uio_seg pairs that were
later fed into NDINIT. Update other call sites accordingly.

Remove the "struct lwp *" argument from all VFS and VOP interfaces.
The general trend is to remove it from all kernel interfaces and

It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes

It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.

Change dk_lookup() to accept an additional argument of the type enum uio_seg
that tells whether the given path is in user space or kernel space, so it
can tell NDINIT().
While the raidframe calls were ok, both ccd(4) and cgd(4) were passing
pointers to user space data, which leads to strange error on i386, as
reported by Jukka Salmi on current-users.

The issue has been there since last august, I'm actually a bit surprised
that no one in the meantime has used ccd(4) or cgd(4) on an arch where it
would have simply faulted.

- Pass the error number and residual count to biodone(), and let it handle
  setting error indicators. Prepare to eliminate B_ERROR.
- Add a flag argument to brelse() to be set into the buf's flags, instead
  of doing it directly. Typically used to set B_INVAL.
- Add a "struct cpu_info *" argument to kthread_create(), to be used to
  create bound threads. Change "bool mpsafe" to "int flags".
- Allow exit of LWPs in the IDL state when (l != curlwp).
- More locking fixes & conversion to the new API.

Modified the dksubr routines to:

	o  expect the disk's start routine to return an int.  If the
	   int is non-zero, we enqueue the request and try again
	   later.
	o  have a dk_start() routine which runs the request queue.
	o  have a dk_iodone() function which should be called by the
	   driver using the framwork from its iodone.  dk_iodone will
	   retry the queue since presumably further progress may be
	   possible once a request is complete.  It is required that
	   the underlying driver have the resources to keep at least
	   one transaction in flight at any time.

Modified cgd to:

	o  be able to keep one transaction in flight at any time
	   (almost) by keeping a buffer of size MAXPHYS in its softc
	   and use it.

We still need to make the cgd_cbufpool per device rather than global
and provide a low water mark for it.

Addresses PR: kern/24715
(at least according to the submitter.)

Fix a longstanding bug in key-handling for the blowfish cipher.

This is an incompatible change, and will break all existing cgd images
encrypted with blowfish. Users will need to dump their data before
booting a kernel with this change, and recreate cgd's and restore data
afterwards.

I believe this affects a very small number of users other than myself;
indeed after several alert mails in an attempt to find them, only 2
such users have come forward. They have both agreed the requirement
for backwards compatibility does not warrant the effort nor the mess
in the code.  This code does exist, if it should later prove to be
needed, but will not be in the tree.

Further, by the nature of the issue, I have strong reasons to believe
that, even if they missed these mails, there would be few other users
of blowfish who update their systems with any regularity; any such
users would have tripped over the problem in the same way I did when
it was first found over a year ago.

The problem stems from two issues with the underlying blowfish
encryption routines used by cgd:
 - they take key length arguments counted in bytes, rather than bits
   like all the opther ciphers.
 - they silently truncate any keys longer than an internal limit,
   rather than returning an error (which would have exposed the
   previous discrepancy immediately).

As a result, the kernel reads too much data as the key from cgdconfig,
and then truncates most of it. This can easily be demonstrated/tested.
Currently, Blowfish users will find that if they mis-enter the cgd
passphrase on the first attempt, when validation fails and cgdconfig
prompts for the passphrase again, the cgd will not correctly configure
even when given a correct passphrase.

Make VOP_STRATEGY(bp) a real VOP as discussed on tech-kern.

VOP_STRATEGY(bp) is replaced by one of two new functions:

- VOP_STRATEGY(vp, bp)  Call the strategy routine of vp for bp.
- DEV_STRATEGY(bp)      Call the d_strategy routine of bp->b_dev for bp.

DEV_STRATEGY(bp) is used only for block-to-block device situations.

Apply the aborted ktrace-lwp changes to a specific branch.  This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it.  This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

implement separate read/write disk statistics:
	- disk_unbusy() gets a new parameter to tell the IO direction.
	- struct disk_sysctl gets 4 new members for read/write bytes/transfers.
	when processing hw.diskstats, add the read&write bytes/transfers for
	the old combined stats to attempt to keep backwards compatibility.

unfortunately, due to multiple bugs, this will cause new kernels and old
vmstat/iostat/systat programs to fail.  however, the next time this is
change it will not fail again.

this is just the kernel portion.
