68a66d149a net_sched: fix order of queue length updates in qdisc_replace()
This important to call qdisc_tree_reduce_backlog() after changing queue
length. Parent qdisc should deactivate class in ->qlen_notify() called from
qdisc_tree_reduce_backlog() but this happens only if qdisc->q.qlen in zero.

Missed class deactivations leads to crashes/warnings at picking packets
from empty qdisc and corrupting state at reactivating this class in future.

138b57f0f8 net: ibm: emac: Fix some error handling path in 'emac_probe()'
If 'irq_of_parse_and_map()' or 'of_address_to_resource()' fail, 'err' is
known to be 0 at this point.
So return -ENODEV instead in the first case and use 'of_iomap()' instead of
the equivalent 'of_address_to_resource()/ioremap()' combinaison in the 2nd
case.

Doing so, the 'rsrc_regs' field of the 'emac_instance struct' becomes
redundant and is removed.

While at it, turn a 'err != 0' test into an equivalent 'err' to be more
consistent.

274043c6c9 bpf: fix double free from dev_map_notification()
In the current code, dev_map_free() can still race with dev_map_notification().
In dev_map_free(), we remove dtab from the list of dtabs after we purged
all entries from it. However, we don't do xchg() with NULL or the like,
so the entry at that point is still pointing to the device. If a unregister
notification comes in at the same time, we therefore risk a double-free,
since the pointer is still present in the map, and then pushed again to
__dev_map_entry_free().

All this is completely unnecessary. Just remove the dtab from the list
right before the synchronize_rcu(), so all outstanding readers from the
notifier list have finished by then, thus we don't need to deal with this
corner case anymore and also wouldn't need to nullify dev entires. This is
fine because we iterate over the map releasing all entries and therefore
dev references anyway.

a0aeb3b2ac Merge tag 'drm-amdkfd-next-2017-08-18' of git://people.freedesktop.org/~gabbayo/linux into drm-next
This is the amdkfd pull request for 4.14 merge window.
AMD has started cleaning the pipe and sending patches from their internal
development to the upstream community.

The plan as I understand it is to first get all the non-dGPU patches to
upstream and then move to upstream dGPU support.

The patches here are relevant only for Kaveri and Carrizo.

The following is a summary of the changes:
- Add new IOCTL to set a Scratch memory VA
- Update PM4 headers for new firmware that support scratch memory
- Support image tiling mode
- Remove all uses of BUG_ON
- Various Bug fixes and coding style fixes

2bfbe7881e kbuild: Do not use hyphen in exported variable name
This definition in Makefile.dtbinst:

    export dtbinst-root ?= $(obj)

should define and export dtbinst-root when handling the root dts
directory, and do nothing in the subdirectories.  However some shells,
including dash, will not pass through environment variables whose name
includes a hyphen.  Usually GNU make does not use a shell to recurse,
but if e.g. $(srctree) contains '~' it will use a shell here.

Rename the variable to dtbinst_root.

8c97023cf0 Kbuild: use -fshort-wchar globally
Commit 971a69db7d ("Xen: don't warn about 2-byte wchar_t in efi")
added the --no-wchar-size-warning to the Makefile to avoid this
harmless warning:

arm-linux-gnueabi-ld: warning: drivers/xen/efi.o uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail

Changing kbuild to use thin archives instead of recursive linking
unfortunately brings the same warning back during the final link.

The kernel does not use wchar_t string literals at this point, and
xen does not use wchar_t at all (only efi_char16_t), so the flag
has no effect, but as pointed out by Jan Beulich, adding a wchar_t
string literal would be bad here.

Since wchar_t is always defined as u16, independent of the toolchain
default, always passing -fshort-wchar is correct and lets us
remove the Xen specific hack along with fixing the warning.

197e7e5213 Sanitize 'move_pages()' permission checks
The 'move_paghes()' system call was introduced long long ago with the
same permission checks as for sending a signal (except using
CAP_SYS_NICE instead of CAP_SYS_KILL for the overriding capability).

That turns out to not be a great choice - while the system call really
only moves physical page allocations around (and you need other
capabilities to do a lot of it), you can check the return value to map
out some the virtual address choices and defeat ASLR of a binary that
still shares your uid.

So change the access checks to the more common 'ptrace_may_access()'
model instead.

This tightens the access checks for the uid, and also effectively
changes the CAP_SYS_NICE check to CAP_SYS_PTRACE, but it's unlikely that
anybody really _uses_ this legacy system call any more (we hav ebetter
NUMA placement models these days), so I expect nobody to notice.

Famous last words.

This commit enables building of the new driver. For this version, all
routines are built into a single module r8822be. When this driver is
moved to the wireless tree, halmac, phydm, and rtl8822be will become
new modules.

9ce99b04b5 staging: r8822be: Add phydm mini driver
The RTL8822BE, an 802.11ac wireless network card, is now appearing in
new computers. Its driver is being placed in staging to reduce the time
that users of this new card will have access to in-kernel drivers.

New Realtek wireless devices have a new method for PHY control and
dynamic management. The RTL8822BE is the first of these devices, thus
there is additional code required.

In the final version, this code will be a separate module; however,
it is combined with the r8822be driver to minimize the interference
with the drivers in the wireless tree.

The RTL8822BE, an 802.11ac wireless network card, is now appearing in
new computers. Its driver is being placed in staging to reduce the time
that users of this new card will have access to in-kernel drivers.

New Realtek devices implement a common sub-driver to control the MAC
layer. The RTL8822BE is the first of these devices, thus its introduction
involves some extra code. In the wireless tree, this will be a separate
module; however, it is compiled into the 8822be driver here.

53a75f22e7 NFS: Fix NFSv2 security settings
For a while now any NFSv2 mount where sec= is specified uses
AUTH_NULL. If sec= is not specified, the mount uses AUTH_UNIX.
Commit e68fd7c807 ("mount: use sec= that was specified on the
command line") attempted to address a very similar problem with
NFSv3, and should have fixed this too, but it has a bug.

The MNTv1 MNT procedure does not return a list of security flavors,
so our client makes up a list containing just AUTH_NULL. This should
enable nfs_verify_authflavors() to assign the sec= specified flavor,
but instead, it incorrectly sets it to AUTH_NULL.

I expect this would also be a problem for any NFSv3 server whose
MNTv3 MNT procedure returned a security flavor list containing only
AUTH_NULL.

Fixes: e68fd7c807 ("mount: use sec= that was specified on ... ")

b79e87e070 NFSv4.1: don't use machine credentials for CLOSE when using 'sec=sys'
An NFSv4.1 client might close a file after the user who opened it has
logged off.  In this case the user's credentials may no longer be
valid, if they are e.g. kerberos credentials that have expired.

NFSv4.1 has a mechanism to allow the client to use machine credentials
to close a file.  However due to a short-coming in the RFC, a CLOSE
with those credentials may not be possible if the file in question
isn't exported to the same security flavor - the required PUTFH must
be rejected when this is the case.

Specifically if a server and client support kerberos in general and
have used it to form a machine credential, but the file is only
exported to "sec=sys", a PUTFH with the machine credentials will fail,
so CLOSE is not possible.

As RPC_AUTH_UNIX (used by sec=sys) credentials can never expire, there
is no value in using the machine credential in place of them.
So in that case, just use the users credentials for CLOSE etc, as you would
in NFSv4.0

fd01b25979 SUNRPC: ECONNREFUSED should cause a rebind.
If you
 - mount and NFSv3 filesystem
 - do some file locking which requires the server
   to make a GRANT call back
 - unmount
 - mount again and do the same locking

then the second attempt at locking suffers a 30 second delay.
Unmounting and remounting causes lockd to stop and restart,
which causes it to bind to a new port.
The server still thinks the old port is valid and gets ECONNREFUSED
when trying to contact it.
ECONNREFUSED should be seen as a hard error that is not worth
retrying.  Rebinding is the only reasonable response.

This patch forces a rebind if that makes sense.
