After the subdriver's remove() routine has completed, the card's layer
mode is undetermined again. Reflect this in the layer2 field.
If qeth_dev_layer2_store() hits an error after remove() was called, the
card _always_ requires a setup(), even if the previous layer mode is
requested again.
But qeth_dev_layer2_store() bails out early if the requested layer mode
still matches the current one. So unless we reset the layer2 field,
re-probing the card back to its previous mode is currently not possible.

By updating q->used_buffers only _after_ do_QDIO() has completed, there
is a potential race against the buffer's TX completion. In the unlikely
case that the TX completion path wins, qeth_qdio_output_handler() would
decrement the counter before qeth_flush_buffers() even incremented it.

pull-request: bpf-next 2018-07-20
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add sharing of BPF objects within one ASIC: this allows for reuse of
the same program on multiple ports of a device, and therefore gains
better code store utilization. On top of that, this now also enables
sharing of maps between programs attached to different ports of a
device, from Jakub.
2) Cleanup in libbpf and bpftool's Makefile to reduce unneeded feature
detections and unused variable exports, also from Jakub.
3) First batch of RCU annotation fixes in prog array handling, i.e.
there are several __rcu markers which are not correct as well as
some of the RCU handling, from Roman.
4) Two fixes in BPF sample files related to checking of the prog_cnt
upper limit from sample loader, from Dan.
5) Minor cleanup in sockmap to remove a set but not used variable,
from Colin.

Make /sys/class/net per net namespace objects belong to container
This is a revival of an older patch set from Dmitry Torokhov:
https://lore.kernel.org/lkml/1471386795-32918-1-git-send-email-dmitry.torokhov@gmail.com/
My submission of v2 is here:
https://lore.kernel.org/lkml/1531497949-1766-1-git-send-email-tyhicks@canonical.com/
Here's Dmitry's description:
There are objects in /sys hierarchy (/sys/class/net/) that logically
belong to a namespace/container. Unfortunately all sysfs objects start
their life belonging to global root, and while we could change
ownership manually, keeping tracks of all objects that come and go is
cumbersome. It would be better if kernel created them using correct
uid/gid from the beginning.
This series changes kernfs to allow creating object's with arbitrary
uid/gid, adds get_ownership() callback to ktype structure so subsystems
could supply their own logic (likely tied to namespace support) for
determining ownership of kobjects, and adjusts sysfs code to make use
of this information. Lastly net-sysfs is adjusted to make sure that
objects in net namespace are owned by the root user from the owning
user namespace.
Note that we do not adjust ownership of objects moved into a new
namespace (as when moving a network device into a container) as
userspace can easily do it.
I'm reviving this patch set because we would like this feature for
system containers. One specific use case that we have is that libvirt is
unable to configure its bridge device inside of a system container due
to the bridge files in /sys/class/net/ being owned by init root instead
of container root. The last two patches in this set are patches that
I've added to Dmitry's original set to allow such configuration of the
bridge device.
Eric had previously provided feedback that he didn't favor these changes
affecting all layers of the stack and that most of the changes could
remain local to drivers/base/core.c. That feedback is certainly sensible
but I wanted to send out v2 of the patch set without making that large
of a change since quite a bit of time has passed and the bridge changes
in the last patch of this set shows that not all of the changes will be
local to drivers/base/core.c. I'm happy to make the changes if the
original request still stands.
* Changes since v2:
- Added my Co-Developed-by and Signed-off-by tags to all of Dmitry's
patches that I've modified
- Patch 1 received build failure fixes in
arch/x86/kernel/cpu/intel_rdt_rdtgroup.c
- Patch 2 was updated to drop the declaration of sysfs_add_file() from
sysfs.h since the patch removed all other uses of the function
- Patch 5 is a new patch that prevents tx_maxrate from being written
to from inside of a container
+ Maybe I'm being too cautious here but the restriction can always
be loosened up later
- Patches 6 and 7 were updated to make net_ns_get_ownership() always
initialize uid and gid, even when the network namespace is NULL, so
that it isn't a dangerous function to reuse
+ Requested by Christian Brauner
- I've looked at all sysfs attributes affected by this patch set and
feel comfortable about the changes. There are quite a few affected
attributes that don't have any capable()/ns_capable() checks in
their store operations (per_bond_attrs, at91_sysfs_attrs,
sysfs_grcan_attrs, ican3_sysfs_attrs, cdc_ncm_sysfs_attrs,
qmi_wwan_sysfs_attrs) but I think this is acceptable. It means that
container root, rather than specifically CAP_NET_ADMIN inside of the
network namespace that the device belongs to, can write to those
device attributes. It's the same situation that those devices have
today in that init root is able to write to the attributes without
necessarily having CAP_NET_ADMIN. I think that this should probably
be fixed in order to be consistent with what netdev_store() does by
verifying CAP_NET_ADMIN in the network namespace but that it doesn't
need to happen in this patch set.

Make net_ns_get_ownership() reusable by networking code outside of core.
This is useful, for example, to allow bridge related sysfs files to be
owned by container root.
Add a function comment since this is a potentially dangerous function to
use given the way that kobject_get_ownership() works by initializing uid
and gid before calling .get_ownership().

Normally kobjects and their sysfs representation belong to global root,
however it is not necessarily the case for objects in separate namespaces.
For example, objects in separate network namespace logically belong to the
container's root and not global root.
This change lays groundwork for allowing network namespace objects
ownership to be transferred to container's root user by defining
get_ownership() callback in ktype structure and using it in sysfs code to
retrieve desired uid/gid when creating sysfs objects for given kobject.

This change allows creating kernfs files and directories with arbitrary
uid/gid instead of always using GLOBAL_ROOT_UID/GID by extending
kernfs_create_dir_ns() and kernfs_create_file_ns() with uid/gid arguments.
The "simple" kernfs_create_file() and kernfs_create_dir() are left alone
and always create objects belonging to the global root.
When creating symlinks ownership (uid/gid) is taken from the target kernfs
object.

* tag 'nds32-for-linus-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/greentime/linux:
nds32: fix build error "relocation truncated to fit: R_NDS32_25_PCREL_RELA" when make allyesconfig
nds32: To simplify the implementation of update_mmu_cache()
nds32: Fix the dts pointer is not passed correctly issue.
nds32: To implement these icache invalidation APIs since nds32 cores don't snoop data cache. This issue is found by Guo Ren. Based on the Documentation/core-api/cachetlb.rst and it says:
nds32: Fix build error caused by configuration flag rename
nds32: define __NDS32_E[BL]__ for sparse
Fix a relatively old initialization issue in intel_pstate causing
the pcc-cpufreq driver to be used instead of it on some HP Proliant
systems, which turned into a functional regression during the 4.17
cycle, because pcc-cpufreq is a scalability disaster and that was
amplified by the idle loop rework done at that time (Rafael Wysocki).

Pull ACPI fix from Rafael Wysocki:
"Extend the recently added suspend-to-idle quirk for Thinkpad X1 Carbon
6th to other systems from that familiy which turned out to need it too

ACPI / EC: Use ec_no_wakeup on more Thinkpad X1 Carbon 6th systems
Fix return code check for "max brightness" ACPI call.
The Dell laptop ACPI video brightness control is not present on dell
laptops anymore, but was present in older kernel versions.
The code that checks the return value is incorrect since the SMM
refactoring.
The old code was:
if (buffer->output[0] == 0)
Which was changed to:
ret = dell_send_request(...)
if (ret)
However, dell_send_request() will return 0 if buffer->output[0] == 0,
so we must change the check to:
if (ret == 0)
This issue was found on a Dell M4800 laptop, and the fix tested on it
as well.
