In the zoned storage model, the sectors within a zone are typically all
writeable. With the introduction of the Zoned Namespace (ZNS) Command
Set in the NVM Express organization, the model was extended to have a
specific writeable capacity.
Extend the zone descriptor data structure with a zone capacity field to
indicate to the user how many sectors in a zone are writeable.
Introduce backward compatibility in the zone report ioctl by extending
the zone report header data structure with a flags field to indicate if
the capacity field is available.

Sometimes it's handy to know when the socket gets freed. In
particular, we'd like to try to use a smarter allocation of
ports for bpf_bind and explore the possibility of limiting
the number of SOCK_DGRAM sockets the process can have.
Implement BPF_CGROUP_INET_SOCK_RELEASE hook that triggers on
inet socket release. It triggers only for userspace sockets
(not in-kernel ones) and therefore has the same semantics as
the existing BPF_CGROUP_INET_SOCK_CREATE.

Initially the thermal framework had a very simple notification
mechanism to send generic netlink messages to the userspace.
The notification function was never called from anywhere and the
corresponding dead code was removed. It was probably a first attempt
to introduce the netlink notification.
At LPC2018, the presentation "Linux thermal: User kernel interface",
proposed to create the notifications to the userspace via a kfifo.
The advantage of the kfifo is the performance. It is usually used from
a 1:1 communication channel where a driver captures data and sends it
as fast as possible to a userspace process.
The drawback is that only one process uses the notification channel
exclusively, thus no other process is allowed to use the channel to
get temperature or notifications.
This patch defines a generic netlink API to discover the current
thermal setup and adds event notifications as well as temperature
sampling. As any genetlink protocol, it can evolve and the versioning
allows to keep the backward compatibility.
In order to prevent the user from getting flooded with data on a
single channel, there are two multicast channels, one for the
temperature sampling when the thermal zone is updated and another one
for the events, so the user can get the events only without the
thermal zone temperature sampling.
Also, a list of commands to discover the thermal setup is added and
can be extended when needed.

AFU (Accelerated Function Unit) is dynamic region of the DFL based FPGA,
and always defined by users. Some DFL based FPGA cards allow users to
implement their own interrupts in AFU. In order to support this,
hardware implements a new UINT (AFU Interrupt) private feature with
related capability register which describes the number of supported
AFU interrupts as well as the local index of the interrupts for
software enumeration, and from software side, driver follows the common
DFL interrupt notification and handling mechanism, and it implements
two ioctls below for user to query number of irqs supported and set/unset
interrupt triggers.
Ioctls:
* DFL_FPGA_PORT_UINT_GET_IRQ_NUM
get the number of irqs, which is used to determine how many interrupts
UINT feature supports.
* DFL_FPGA_PORT_UINT_SET_IRQ
set/unset eventfds as AFU interrupt triggers.

Framebuffer Compression
Amlogic uses a proprietary lossless image compression protocol and format
for their hardware video codec accelerators, either video decoders or
video input encoders.
It considerably reduces memory bandwidth while writing and reading
frames in memory.
The underlying storage is considered to be 3 components, 8bit or 10-bit
per component, YCbCr 420, single plane :
- DRM_FORMAT_YUV420_8BIT
- DRM_FORMAT_YUV420_10BIT
This modifier will be notably added to DMA-BUF frames imported from the V4L2
Amlogic VDEC decoder.
This introduces the basic layout composed of:
- a body content organized in 64x32 superblocks with 4096 bytes per
superblock in default mode.
- a 32 bytes per 128x64 header block
This layout is tranferrable between Amlogic SoCs supporting this modifier.
The Memory Saving option exist changing the layout superblock size to save memory when
using 8bit components pixels size.
Finally is also adds the Scatter Memory layout, meaning the header contains IOMMU
references to the compressed frames content to optimize memory access
and layout.
In this mode, only the header memory address is needed, thus the content
memory organization is tied to the current producer execution and cannot
be saved/dumped neither transferrable between Amlogic SoCs supporting this
modifier.

Introduce helper bpf_get_task_stack(), which dumps stack trace of given
task. This is different to bpf_get_stack(), which gets stack track of
current task. One potential use case of bpf_get_task_stack() is to call
it from bpf_iter__task and dump all /proc/<pid>/stack to a seq_file.
bpf_get_task_stack() uses stack_trace_save_tsk() instead of
get_perf_callchain() for kernel stack. The benefit of this choice is that
stack_trace_save_tsk() doesn't require changes in arch/. The downside of
using stack_trace_save_tsk() is that stack_trace_save_tsk() dumps the
stack trace to unsigned long array. For 32-bit systems, we need to
translate it to u64 array.

Some PCIe devices do not expect a PASID value in PRI Page Responses.
If the "PRG Response PASID Required" bit in the PRI capability is zero,
then the OS should not set the PASID field. Similarly on Arm SMMU,
responses to stall events do not have a PASID.
Currently iommu_page_response() systematically checks that the PASID in
the page response corresponds to the one in the page request. This can't
work with virtualization because a page response coming from a guest OS
won't have a PASID if the passed-through device does not require one.
Add a flag to page requests that declares whether the corresponding
response needs to have a PASID. When this flag isn't set, allow page
responses without PASID.

Currently, drivers can only tell whether the link is up/down using
LINKSTATE_GET, but no additional information is given.
Add attributes to LINKSTATE_GET command in order to allow drivers
to expose the user more information in addition to link state to ease
the debug process, for example, reason for link down state.
Extended state consists of two attributes - link_ext_state and
link_ext_substate. The idea is to avoid 'vendor specific' states in order
to prevent drivers to use specific link_ext_state that can be in the future
common link_ext_state.
The substates allows drivers to add more information to the common
link_ext_state. For example, vendor can expose 'Autoneg' as link_ext_state
and add 'No partner detected during force mode' as link_ext_substate.
If a driver cannot pinpoint the extended state with the substate
accuracy, it is free to expose only the extended state and omit the
substate attribute.

In order to allow acting on dropped and/or ECN-marked packets, add two new
qevents to the RED qdisc: "early_drop" and "mark". Filters attached at
"early_drop" block are executed as packets are early-dropped, those
attached at the "mark" block are executed as packets are ECN-marked.
Two new attributes are introduced: TCA_RED_EARLY_DROP_BLOCK with the block
index for the "early_drop" qevent, and TCA_RED_MARK_BLOCK for the "mark"
qevent. Absence of these attributes signifies "don't care": no block is
allocated in that case, or the existing blocks are left intact in case of
the change callback.
For purposes of offloading, blocks attached to these qevents appear with
newly-introduced binder types, FLOW_BLOCK_BINDER_TYPE_RED_EARLY_DROP and
FLOW_BLOCK_BINDER_TYPE_RED_MARK.

FPGA user applications may be interested in interrupts generated by
DFL features. For example, users can implement their own FPGA
logics with interrupts enabled in AFU (Accelerated Function Unit,
dynamic region of DFL based FPGA). So user applications need to be
notified to handle these interrupts.
In order to allow userspace applications to monitor interrupts,
driver requires userspace to provide eventfds as interrupt
notification channels. Applications then poll/select on the eventfds
to get notified.
This patch introduces a generic helper functions to do eventfds binding
with given interrupts.
Sub feature drivers are expected to use XXX_GET_IRQ_NUM to query irq
info, and XXX_SET_IRQ to set eventfds for interrupts. This patch also

In some setups multiple hard interfaces with similar link qualities
or throughput values are available. But people have expressed the desire
to consider one of them as a backup only.
Some creative solutions are currently in use: Such people are
configuring multiple batman-adv mesh/soft interfaces, wire them
together with some veth pairs and then tune the hop penalty to achieve
an effect similar to a tunable per interface hop penalty.
This patch introduces a new, configurable, per hard interface hop penalty
to simplify such setups.

git://anongit.freedesktop.org/drm/drm-misc into drm-fixes
Short summary of fixes pull (less than what git shortlog provides):
* In mcde, set up fbdev after device registration and removde the last access
to dev->dev_private. Fixes an error message and a segmentation fault.
* Set the connector type for LogicPT Type 28 and newhaven_nhd_43_480272ef_atxl
panels.
* In uvesafb, fix the handling of the noblank option.
* Fix panel orientation for Asus T101HA and Acer S1003.
* Fix DMA configuration for sun4i if IOMMU is present.
* Fix regression in VT restoration. Unbreaks userspace (i.e., Xorg) VT handling.

The helper is used in tracing programs to cast a socket
pointer to a tcp6_sock pointer.
The return value could be NULL if the casting is illegal.
A new helper return type RET_PTR_TO_BTF_ID_OR_NULL is added
so the verifier is able to deduce proper return types for the helper.
Different from the previous BTF_ID based helpers,
the bpf_skc_to_tcp6_sock() argument can be several possible
btf_ids. More specifically, all possible socket data structures
with sock_common appearing in the first in the memory layout.
This patch only added socket types related to tcp and udp.
All possible argument btf_id and return value btf_id
for helper bpf_skc_to_tcp6_sock() are pre-calculcated and
cached. In the future, it is even possible to precompute
these btf_id's at kernel build time.

When we modify or create a new fdb entry sometimes we want to avoid
refreshing its activity in order to track it properly. One example is
when a mac is received from EVPN multi-homing peer by FRR, which doesn't
want to change local activity accounting. It makes it static and sets a
flag to track its activity.
