fix vnode lock assertion for extended attributes directory

Background.  In ZFS a file with extended attributes has a special
directory associated with it where each extended attribute is a file.
The attribute's name is a file name and its value is a file content.
When the ownership of a file with extended attributes is changed, ZFS
also changes ownership of the special directory.  This is where the bug
was hit.

The bug was introduced in r209158.

Nota bene.  ZFS vnode locks are typically acquired before
z_teardown_lock (i.e., before ZFS_ENTER).  But this is not the case for
the vnodes that represent the extended attribute directory and files.
Those are always locked after ZFS_ENTER.  This is confusing and fragile.

amdsbwd, intpm: unify bits specific to AMD chipsets (FCHs, southbridges)

AMD chipsets have proprietary mechanisms for dicovering resources.
Those resources are not discoverable via plug-and-play mechanisms
like PCI configuration registers or ACPI.
For this reason a chipset-specific knowledge of proprietary registers
is required.

At present there are two FreeBSD drivers that require the proprietary
resource discovery.  One is amdsbwd which is a driver for the watchdog
timer in the AMD chipsets.  The other is intpm SMBus driver when it
attaches to the newer AMD chipsets where the resources of the SMBus HBA
are not described in the regular PCI way.

In both cases the resources are discovered by accessing AMD PMIO space.
Thus, many definitions are shared between the two drivers.
This change puts those defintions into a common header file.

As an added benefit, intpm driver now supports newest FCHs built into
AMD processors of Family 15h, models 70h-7Fh and Family 16h, models
30h-3Fh.

Fix regression from r297400, which truncates headers in case of low socket
buffer and put a small optimization for low socket buffer case:

- Do not hack uio_resid, and let m_uiotombuf() properly take care of it. This
  fixes truncation of headers at low buffer.
- If headers ate all the space, jump right to the end of the cycle, to
  avoid doing single page I/O and allocating zero length mbuf.
- Clear hdr_uio only if space is positive, which indicates that all uio
  was copied in.

This wasn't a problem when the NICs were configured to only process

Once avos and I flipped on "beacons from all BSSIDs" to allow for
correct IBSS merging, we found this interesting behaviour.

This adds a check against the current SSID.

* If there's no VAP SSID, allow anything
* If there's a VAP SSID, check if the incoming frame has a suitable
  SSID and if so, allow it.

This prevents nodes being created for other SSIDs in probe and beacon
frames - ie, beacons overlapping IBSSes with different SSIDs, and
probe requests from arbitrary devices.

kib [Wed, 21 Sep 2016 11:31:58 +0000 (11:31 +0000)]
Add kernel interfaces to call EFI Runtime Services.

Runtime services require special execution environment for the call.
Besides that, OS must inform firmware about runtime virtual memory map
which will be active during the calls, with the SetVirtualAddressMap()
runtime call, done while the 1:1 mapping is still used.  There are two
complication: the SetVirtualAddressMap() effectively must be done from
loader, which needs to know kernel address map in advance.  More,
despite not explicitely mentioned in the specification, both 1:1 and
the map passed to SetVirtualAddressMap() must be active during the
SetVirtualAddressMap() call.  Second, there are buggy BIOSes which
require both mappings active during runtime calls as well, most likely
because they fail to identify all relocations to perform.

On amd64, we can get rid of both problems by providing 1:1 mapping for
the duration of runtime calls, by temprorary remapping user addresses.
As result, we avoid the need for loader to know about future kernel
address map, and avoid bugs in BIOSes.  Typically BIOS only maps
something in low 4G.  If not runtime bugs, we would take advantage of
the DMAP, as previous versions of this patch did.

Similar but more complicated trick can be used even for i386 and 32bit
runtime, if and when the EFI boot on i386 is supported.  We would need
a trampoline page, since potentially whole 4G of VA would be switched
on calls, instead of only userspace portion on amd64.

Context switches are disabled for the duration of the call, FPU access
is granted, and interrupts are not disabled.  The later is possible
because kernel is mapped during calls.

To test, the sysctl mib debug.efi_time is provided, setting it to 1
makes one call to EFI get_time() runtime service, on success the efitm
structure is printed to the control terminal.  Load efirt.ko, or add
EFIRT option to the kernel config, to enable code.

Simple post-mortem reporter for amd64 loader.efi.

There is no way to see anything about the faults occuring in
loader.efi. Some intel BIOSes do output a line into serial port at
115200/8/1 regardless of the current port settings with the EFI error
number, but this is too little, and not always available, esp. if the
user does not know where to look.

The patch adds a simple facility to grab exceptions and at least dump
generic registers and some exception details.  Due to the relative
complexity of correctly taking over the BIOS IDT setup, only install
the facility on user request.

Two new commands, 'grab_faults' and 'ungrab_faults' are provided,
first one takes over, second undoes the first. It is supposed that
user would execute 'grab' by the developer direction of collecting the
debugging data.  The 'fault' command generates exception to test the
setup.

Fault handlers use dedicated stack to improve chances of catching
stack/TSS exceptions.  Due to this, BIOS IDT is duplicated into a
private copy, and debugger needs to find a free GDT slot for TSS. This
is done in somewhat complicated efi_redirect_exceptions().

CLOCK_GETTIME() with the lock.

Now all time-related accesses to the CMOS for RTC should be under the
