do not destroy 'snapdir' when it becomes  inactive

That was just wrong.  In fact, we can safely keep this static entry when
it's inactive.
Now the destructive action is moved to the reclaim method and the
function is renamed from zfsctl_snapdir_inactive(0 to
zfsctl_snapdir_reclaim().

Also, we can use gfs_vop_reclaim() instead of gfs_dir_inactive() +
kmem_free().

Lastly, we can just assert that the node does not any children when it
is reclaimed, even on the force unmount.  That's because zfs_umount()
does an extra vflush() pass which should destroy all snapshot-mountpoint
vnodes that are the snapdir's children.

Those vnodes should not linger.  "Stale" nodes may get out of

snapshot.

While there fix the argument type for zfsctl_snapshot_reclaim().
Also, its original argument can be passed to gfs_vop_reclaim() directly.

fix locking in zfsctl_root_lookup

Dropping the root vnode's lock after VFS_ROOT() didn't really help the
fact that we acquired the lock while holding its child's, .zfs, lock
while performing the operaiton.
So, directly use zfs_zget() to get the root vnode.

While there simplify the code in zfsctl_freebsd_root_lookup.
We know that .zfs is always exclusively locked.
We know that there is already a reference on *vpp, so no need for an
extra one.
Account for the fact that .. lookup may ask for a different lock type,
not necessarily LK_EXCLUSIVE.  And handle a possible failure to acquire
the lock given the lock flags.

MFC after:  5 weeks

299946 by avg:
gfs_lookup_dot() does not have to acquire any locks

In fact, that was dangerous.  For example, zfsctl_snapshot_reclaim()
calls gfs_dir_lookup() on ".." path and that ends up calling
gfs_lookup_dot() which violated locking order by acquiring the parent's
directory vnode lock after the child's vnode lock.

Also, the previous behavior was inconsistent as gfs_dir_lookup()
returned a locked vnode for . and .. lookups, but not for any other.

Now gfs_lookup_dot() just references a resulting vnode and the locking
is done in its consumers, where necessary.
Note that we do not enable shared locking support for any gfs / zfsctl
vnodes.

This commit partially reverts r273641.

299945 by avg:
avoid deadlock between zfsctl_snapdir_lookup and zfsctl_snapshot_reclaim

The former acquired a snap vnode lock while holding sd_lock while the
latter does the opposite.

The solution is drop sd_lock before acquiring the vnode lock.  That
should be okay as we are still holding a lock on the 'snapshot'
directory in the exclusive mode.  That lock ensures that there are no
concurrent lookups in the directory and thus no concurrent mount attempts.

But now we have to account for the possibility that the snap vnode
might get reclaim after we drop sd_lock and before we can get
the node lock.  So, check for that case and retry.

No, those settings are not too early.  However, the routing to different
CPUs now happens earlier than it used to.  What is the line before the
MSI lines?  You can take a picture with your phone/camera if that's simplest.

No, there is absolutely zero/zilch/nada about this that is specific to
Intel CPUs.  Very, very little in FreeBSD is specific to AMD vs Intel
CPUs.  It is, OTOH, quite likely that this is specific to device driver
for a piece of hardware.

This should fix the build on older stable/10, since install is a bootstrap

Pending a decision how to fix this properly, revert utimensat usage. Copies
with the -p option will again appear older than the original almost always,
but -p is not commonly used.

fix a vnode reference leak caused by illumos compat traverse()

This commit partially reverts r273641 which introduced the leak.
It did so to accomodate for some consumers of traverse() that expected
the starting vnode to stay as-is.  But that introduced the leak in the
case when a mounted filesystem was found and its root vnode was
returned.

r299914 removed the troublesome consumers and now there is no reason to
keep the starting vnode.  So, now the new rules are:
- if there is no mounted filesystem, then nothing is changed
- otherwise the starting vnode is always released
- the root vnode of the mounted filesystem is returned locked and
  referenced in the case of success

I tried ctrl-alt-esc, nothing happens.  Maybe because USB isn't
up yet.

Judging from the way the case fan starts ramping up it seems like
the CPU is in a tight loop.

Add a new get_id interface to pci and pcib. This will allow us to both

For the former the interface returns an int to signal an error. The ID is
returned at a uintptr_t * argument.

For the latter there is a type argument that allows selecting the ID type.
This only specifies a single type, however a MSI type will be added
to handle the need to find the ID the hardware passes to the ARM GICv3
interrupt controller.

Introduce MSI and MSI-X support to intrng. This adds a new msi device
interface with 5 methods to mirror the 5 MSI/MSI-X methods in the pcib
interface. The pcib driver will need to perform a device specific lookup
to find the MSI controller and pass this to intrng as the xref. Intrng
will finally find the controller and have it handle the requested operation.

You should be able to enter ddb at this point. Methods depend on the
console used, serial break for serial console, ctrl-alt-esc for sc/vt
AFAIR. If you have IPMI/DRAC/ILO, send nmi.

After getting at ddb> prompt, do 'bt' then 'ps' then 'alltrace' and
show the output.

EARLY_AP_STARTUP hangs during boot

2016-05-16 Thread Gary Jennejohn 
I tried out EARLY_AP_STARTUP, but the kernel hangs and I can't
break into DDB.

I did a verbose boot and the last lines I see are related to routing
MSI-X to various local APIC vectors.  I copied the last few lines and
they look like this:

msi: routing MSI-X IRQ 256 to local APIC 2 vector 48
msi: routing MSI-X IRQ 257 to local APIC 3 vector 48
msi: routing MSI-X IRQ 258 to local APIC 4 vector 48
msi: routing MSI-X IRQ 256 to local APIC 0 vector 49

I tried disabling msi and msix in /boot/loader.conf, but the settings
were ignored (probabaly too early).

I'm running on a AMD Phenom(tm) II X6 1090T Processor.

So, maybe this option only really works correctly on Intel CPUs?

Introduce MSI and MSI-X support to intrng. This adds a new msi device
interface with 5 methods to mirror the 5 MSI/MSI-X methods in the pcib
interface. The pcib driver will need to perform a device specific lookup
to find the MSI controller and pass this to intrng as the xref. Intrng
will finally find the controller and have it handle the requested operation.

zfsctl_ops_snapshot: remove methods should never be called

We pretend that snapshots mounted under .zfs are part of the original
filesystem and we try very hard to hide vnodes on top of which the snapshots
are mounted.  Given that I believe that the removed operations should
never be called.  They might have been called previously because
of issues fixed in r299906, r299908 and r299913.

dounmount: do not call mountcheckdirs() for mounts with MNT_IGNORE

This is a bit hackish, but the flag is currently set only for ZFS
snapshots mounted under .zfs.  mountcheckdirs() can change cdir/rdir
references to a covered vnode.  But for the said snapshots the covered
vnode is really ephemeral and it must never be accessed (except
for a few specific cases).

To do:  consider removing mountcheckdirs() entirely

No he can’t and I haven’t in years either.   Searching bugs might however be a 
good idea;  there is a LOR category or tag somewhere.

Introduce basic etherswitch support for Ralink SoCs

This revision introduces basic support for the internal ESW switch found
Ralink/Mediatek SoCs such as RT3050, RT3352, RT5350, MT7628; and GSW
found in MT7620 and MT7621.

It only supports 802.1q VLANs and doesn't support external PHYs at the
moment (only the ones that are built into the switch itself).

zfsctl_snapdir_lookup: always clear VV_ROOT flag of snapshot's root VV_ROOT

Previosuly we did that only if the snapshot was mounted earlier, its
root vnode got recycled and then we accessed it again.
We never cleared the flag for a freshly mounted snapshot.

That was very inconsistent and probably a source of some bugs.
Or maybe that painted over some bugs which might get revealed now.

We should consistently clear the flag because we try very hard to
pretend that snapshots auto-mounted under .zfs are part of their
original filesystem.  In other words, we try to hide the fact that they
are different filesystems / mountpoints.

add zfs_vptocnp with special handling for snapshots under .zfs

The logic is similar to that already present in zfs_dirlook() to handle
a dot-dot lookup on a root vnode of a snapshot mounted under
.zfs/snapshot/.
illumos does not have an equivalent of vop_vptocnp, so there only the
lookup had to be patched up.

zfsctl: fix several problems with reference counts

* Remove excessive references on a snapshot mountpoint vnode.
  zfsctl_snapdir_lookup() called VN_HOLD() on a vnode returned from
  zfsctl_snapshot_mknode() and the latter also had a call to VN_HOLD()
  on the same vnode.
  On top of that gfs_dir_create() already returns the vnode with the
  use count of 1 (set in getnewvnode).
  So there was 3 references on the vnode.

* mount_snapshot() should keep a reference to a covered vnode.
  That reference is owned by the mountpoint (mounted snapshot filesystem).

* Remove cryptic manipulations of a covered vnode in zfs_umount().
  FreeBSD dounmount() already does the right thing and releases the covered
  vnode.
