As we did recently in commit 158f323b98 ("net: adjust skb->truesize in

via a call to skb_condense().
If all frags were freed, then skb->truesize can be recomputed.
This call can be done if skb is not yet owned, or destructor is

Andrey found a way to trigger the WARN_ON_ONCE(delta < len) in
skb_try_coalesce() using syzkaller and a filter attached to a TCP
socket over loopback interface.
I believe one issue with looped skbs is that tcp_trim_head() can end up
producing skb with under estimated truesize.
It hardly matters for normal conditions, since packets sent over
loopback are never truncated.
Bytes trimmed from skb->head should not change skb truesize, since
skb->head is not reallocated.

On slave list updates, the bonding driver computes its hard_header_len
as the maximum of all enslaved devices's hard_header_len.
If the slave list is empty, e.g. on last enslaved device removal,
ETH_HLEN is used.
Since the bonding header_ops are set only when the first enslaved
device is attached, the above can lead to header_ops->create()
being called with the wrong skb headroom in place.
If bond0 is configured on top of ipoib devices, with the
following commands:
ifup bond0
for slave in $BOND_SLAVES_LIST; do
ip link set dev $slave nomaster
done
ping -c 1 <ip on bond0 subnet>
we will obtain a skb_under_panic() with a similar call trace:

This change addresses the issue avoiding updating the bonding device

Tony Lindgren reports a kernel oops that resulted from my compile-time
fix on the default config. This shows two problems:
a) configurations that did not already enable PTP_1588_CLOCK will
now miss the cpts driver
b) when cpts support is disabled, the driver crashes. This is a
preexisting problem that we did not notice before my patch.
While the second problem is still being investigated, this modifies
the dependencies again, getting us back to the original state, with
another 'select NET_PTP_CLASSIFY' added in to avoid the original
link error we got, and the 'depends on POSIX_TIMERS' to hide
the CPTS support when turning it on would be useless.

To overcome bugs as described and fixed in 89087c456f ("bpf: Fix
values type used in test_maps"), provide a generic BPF_DECLARE_PERCPU()
and bpf_percpu() accessor macro for all percpu map values used in
tests.
Declaring variables works as follows (also works for structs):
BPF_DECLARE_PERCPU(uint32_t, my_value);
They can then be accessed normally as uint32_t type through:
bpf_percpu(my_value, <cpu_nr>)
For example:
bpf_percpu(my_value, 0)++;
Implicitly, we make sure that the passed type is allocated and aligned
by gcc at least on a 8-byte boundary, so that it works together with
the map lookup/update syscall for percpu maps. We use it as a usage
example in test_maps, so that others are free to adapt this into their
code when necessary.

The nvdimm_flush() mechanism helps to reduce the impact of an ADR
(asynchronous-dimm-refresh) failure. The ADR mechanism handles flushing
platform WPQ (write-pending-queue) buffers when power is removed. The
nvdimm_flush() mechanism performs that same function on-demand.
When a pmem namespace is associated with a block device, an
nvdimm_flush() is triggered with every block-layer REQ_FUA, or REQ_FLUSH
request. These requests are typically associated with filesystem
metadata updates. However, when a namespace is in device-dax mode,
userspace (think database metadata) needs another path to perform the
same flushing. In other words this is not required to make data
persistent, but in the case of metadata it allows for a smaller failure
domain in the unlikely event of an ADR failure.
The new 'deep_flush' attribute is visible when the individual DIMMs
backing a given interleave-set are described by platform firmware. In
ACPI terms this is "NVDIMM Region Mapping Structures" and associated
"Flush Hint Address Structures". Reads return "1" if the region supports
triggering WPQ flushes on all DIMMs. Reads return "0" the flush
operation is a platform nop, and in that case the attribute is
read-only.
Why sysfs and not an ioctl? An ioctl requires establishing a new
ioctl function number space for device-dax. Given that this would be
called on a device-dax fd an application could be forgiven for
accidentally calling this on a filesystem-dax fd. Placing this interface
in libnvdimm sysfs removes that potential for collision with a
filesystem ioctl, and it keeps ioctls out of the generic device-dax
implementation.

iTCO_wdt driver need access to PMC_CFG GCR register to modify the
noreboot setting. Currently, this is done by passing PMC_CFG reg
address as memory resource to watchdog driver and allowing it directly
modify the PMC_CFG register. But currently PMC driver also has
requirement to memory map the entire GCR register space in this driver.
This causes mem request failure in watchdog driver. So this patch fixes
this issue by adding API to update noreboot flag and passes them
to watchdog driver via platform data.
