Repair handling of ccd sysctls to not use newp as an index.
This is a work-around for kern/58051. It is not a complete fix.

hannken | Using a ccd(4) with GPT (dk* at ccd*) the disk framework will call
ccdstrategy() -> ccdstart() -> ccdbuffer() from softint context.
Allocating the buffer with PR_WAITOK here is forbidden.
Change ccdstart() / ccdbuffer() to report failure back to caller and
pass PR_WAITOK / PR_NOWAIT as an additional argument.
Call ccdstart() with PR_NOPWAIT from ccdstrategy() and on error defer
to the kthread. Call ccdstart() with PR_WAITOK from kthread so requests
from kthread always succeed to allocate the buffers.
Remove the (non working) throttling on low memory as it is no longer needed.
Fixes PR kern/58043 "kernel crash in assert_sleepable() in -current,
dk(4) driver?"

ad | uvm_availmem(): give it a boolean argument to specify whether a recent
cached value will do, or if the very latest total must be fetched. It can
be called thousands of times a second and fetching the totals impacts not

pgoyette | Many years ago someone created a new __link_set_sysctl_funcs to hold
the list of routines that need to be called for setting up sysctl
variables. This worked great for all code included in the kernel
itself, but didn't deal with modules that want to create their own
sysctl data. So, we ended up with a lot of #ifdef _MODULE blocks
so modules could explicitly call their setup functions when loaded
as non-built-in modules.
So today, we complete the task that was started so many years ago.
When modules are loaded, after we've called xxx_modcmd(INIT...) we
check if the module contains its own __link_set_sysctl_funcs, and
if so we call the functions listed. We add a struct sysctllog member
to the struct module so we can call sysctl_teardown() when the module
gets unloaded. (The sequence of events ensures that the sysctl stuff
doesn't get created until the rest of the module's init code does any
required memory allocation.)
So, no more need to explicitly call the sysctl setup routines when
built as a loadable module.

pgoyette | There is currently a counter nactive which tracks the INSERT and REMOVE
of entries in the ccds LIST.
Since the counter is checked only when the ccd module is being unloaded,
remove the counter completely and just check for LIST_EMPTY(ccds).
No functional change intended.

chs | branches: 1.172.2;
remove checks for failure after memory allocation calls that cannot fail:
kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()
all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

jdolecek | branches: 1.171.4;
introduce DKCACHE_COMBINE() macro - it combines the flags in a way that
all common flags are retained, and flags regarding write cache are preserved
if either of the devices has it; callers can thus rely on write cache not
being possible to be used when both flags are missing
use the new macro for ccd(4)
|

jdolecek | support DIOCGCACHE - result is intersection of flags returned by underlying

mlelstv | Enhance disk metrics by calculating a weighted sum that is incremented
by the number of concurrent I/O requests. Also introduce a new disk_wait()
function to measure requests waiting in a bufq.
iostat -y now reports data about waiting and active requests.
So far only drivers using dksubr and dk, ccd, wd and xbd collect data about
waiting requests.

pgoyette | Create the kern.ccd sysctl sub-tree when built as a module. Even though
the contents of the sub-tree are all structures, and thus not displayed
via sysctl(8), the info is potentially useful to programs. (For example,
ccdconfig could use this to determine how many units are available.)
The sub-tree is already available when the module is included as built-in
module.

christos | We have three sets of DTYPE_ constants in the kernel:
altq Drop Type
disklabel Disk Type
file Descriptor Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.
|

rmind | 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.

dholland | 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.

cube | 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.

- 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.

gehenna | Merge the gehenna-devsw branch into the trunk.
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

Pool deals fairly well with physical memory shortage, but it doesn't
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map). Try to deal with this:
* Group all information about the backend allocator for a pool in a
separate structure. The pool references this structure, rather than
the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
to become available, but will still fail if it cannot callocate KVA
space for the pages. If this happens, carefully drain all pools using
the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
some pages, and use that information to make draining easier and more
efficient.
* Get rid of PR_URGENT. There was only one use of it, and it could be
dealt with by the caller.

thorpej | A performance optimization, inspired by a conversation with Thor Simon:
- Keep a freelist of component buffer headers, defaulting
to 8 headers per component (tunable with the CCDNBUF
kernel compile option).
- When allocating a component buffer, try to pull a header
off the freelist first, falling back on MALLOC() if the
freelist is empty. Use MALLOC() rather than malloc(),
because it will attempt to short-cut the allocation before
actually making a full-blown malloc() call.
- Keep statistics on how many component buffer headers have
been allocated and how many of those allocations have
resulted in freelist misses.
With these changes, I observed measurable decreases in system and
wall clock time on operations on an 8G ccd, as well as a measurable
drop in the time spent in ccdbuffer() (measured with kernel profiling).

thorpej | New generic disk framework. Highlights:
- New metrics handling. Metrics are now kept in the new

transfer count in bytes.
- Storage for disklabels is now dynamically allocated, so that
the size of the disk structure is not machine-dependent.
- Several new functions for attaching and detaching disks, and
handling metrics calculation.
Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.
For usage and architectural details, see the forthcoming disk(9) manual
page.

fvdl | * add a VCLONED vnode flag that indicates a vnode representing a cloned
device.
* rename REVOKEALL to REVOKEALIAS, and add a REVOKECLONE flag, to pass
to VOP_REVOKE
* the revoke system call will revoke all aliases, as before, but not the
clones
* vdevgone is called when detaching a device, so make it use REVOKECLONE
to get rid of all clones as well
* clean up all uses of VOP_OPEN wrt. locking.
* add a few VOPS to spec_vnops that need to do something when it's a
clone vnode (access and getattr)
* add a copy of the vnode vattr structure of the original 'master' vnode
to the specinfo of a cloned vnode. could possibly redirect getattr to
the 'master' vnode, but this has issues with revoke
* add a vdev_reassignvp function that disassociates a vnode from its
original device, and reassociates it with the specified dev_t. to be
used by cloning devices only, in case a new minor is allocated.
* change all direct references in drivers to v_devcookie and v_rdev
to vdev_privdata(vp) and vdev_rdev(vp). for diagnostic purposes
when debugging race conditions that still exist wrt. locking and
revoking vnodes.
* make the locking state of a vnode consistent when passed to
d_open and d_close (unlocked). locked would be better, but has
some deadlock issues

thorpej | Commit my "devvp" changes to the thorpej-devvp branch. This
replaces the use of dev_t in most places with a struct vnode *.
This will form the basic infrastructure for real cloning device
support (besides being architecurally cleaner -- it'll be good
to get away from using numbers to represent objects).

darrenr | 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.

* The kernel's struct ccd_softc has extra structure members over the
userland version; provide another ccd global variable (ccd_softc_elemsize)
containing the kernel's size, and use that it ccdconfig(8) to convert the
kernel's ccd_softc into userland versions.
Fixes 'ccdconfig -g'.
* Use DISKUNIT() instead of home-grown cruft to determine the `N' of "ccdN".
Fixes 'ccdconfig -g ccd1'.

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.

is set up is to be revisited.
- Implement soft interrupts as kernel threads. A generic implementation
is provided, with hooks for fast-path MD code that can run the interrupt
threads over the top of other threads executing in the kernel.
- Split vnode::v_flag into three fields, depending on how the flag is
locked (by the interlock, by the vnode lock, by the file system).
- Miscellaneous locking fixes and improvements.
|
| 1.118.2.3 |

ad | - 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".

pgoyette | Convert the MODULE_{,VOID_}HOOK_CALL macros to do everything in-line
rather than defining an intermediate hook##call function. Almost
all of the hooks are called only once, and although we lose the
ability of doing things like
if (MODULE_HOOK_CALL(...) == 0) ...
we simplify things quite a bit. With this change, we no longer need
to have both declaration and definition macros, and the definition
no longer needs to have both prototype argument list and a "real"
argument list.
FWIW, the above if now needs to written as
int ret;
MODULE_HOOK_CALL(..., ret);
if (ret == 0) ...
with appropriate use of braces {}.

pgoyette | Don't restrict hooks to having only int or void types. Pass the hook's
type to the various macros, as needed.
Allows us to reduce diffs to original in at least one or two places (we
no longer have to provide an additional parameter to the hook routine
for returning a non-int return value).

pgoyette | Create a variant of the HOOK macros that handles hook routines of
type void, and use them where appropriate.
|
| 1.175.2.9 |
| 13-Jan-2019 |
pgoyette | Remove the HOOK2 versions of the MODULE_HOOK macros. There were
only a few uses, and using them led to some lack of clarity in the
code. Instead, we now use two separate hooks, with names that
make it clear(er) what we're doing.
This also positions us to start unraveling some of the rtsock_50
mess, which will need (at least) five hooks.

| 1.175.2.8 |
| 29-Sep-2018 |
pgoyette | In MODULE_HOOK_CALL_DECL we don't need to provide the actual argument
list for calling the hook function, nor do we need to provide the
default value (for when the hook has not been set).

pgoyette | The COMPAT_HOOK macros were renamed to MODULE_HOOK, adjust all callers
|
| 1.175.2.6 |
| 18-Sep-2018 |
pgoyette | Split the COMPAT_CALL_HOOK to separate the declaration from the
implementation. Some hooks are called from multiple source files,
and the old method resulted in duplicate implementations.
Implement MP-safe hooks for the usb_subr_30 code. Pass the helper
functions as arguments to the compat code so it does not have to
determine if the kernel contains usb code.

pgoyette | Yay - we got the ccd_ioctl_60 stuff to build!
Now we can use that as a template for cleaning up all the others.

pgoyette | Remove definition of compat_ccd_ioctl_60() - this is now defined in
sys/kern/compat_stub.c (sync/merge botch)

For now, we only handle the dev/ccd and NTP needs; more to follow.

Use raw device for configuring units. This is necessary as
having a block device opened prevents autodiscovery of wedges.
Fix ioctl locking. Add dkdriver.
Check dkdriver before calling a driver function.

martin | Pull up following revision(s) (requested by hannken in ticket #669):
sys/dev/ccd.c: revision 1.190
Using a ccd(4) with GPT (dk* at ccd*) the disk framework will call
ccdstrategy() -> ccdstart() -> ccdbuffer() from softint context.
Allocating the buffer with PR_WAITOK here is forbidden.
Change ccdstart() / ccdbuffer() to report failure back to caller and
pass PR_WAITOK / PR_NOWAIT as an additional argument.
Call ccdstart() with PR_NOPWAIT from ccdstrategy() and on error defer
to the kthread. Call ccdstart() with PR_WAITOK from kthread so requests
from kthread always succeed to allocate the buffers.
Remove the (non working) throttling on low memory as it is no longer needed.
Fixes PR kern/58043 "kernel crash in assert_sleepable() in -current,
dk(4) driver?"
