    By the way, the BPF kernel selftests run with -mcpu=probe for better
    test coverage.
 
+Q: In some cases clang flag "-target bpf" is used but in other cases the
+   default clang target, which matches the underlying architecture, is used.
+   What is the difference and when I should use which?
+
+A: Although LLVM IR generation and optimization try to stay architecture
+   independent, "-target <arch>" still has some impact on generated code:
+
+     - BPF program may recursively include header file(s) with file scope
+       inline assembly codes. The default target can handle this well,
+       while bpf target may fail if bpf backend assembler does not
+       understand these assembly codes, which is true in most cases.
+
+     - When compiled without -g, additional elf sections, e.g.,
+       .eh_frame and .rela.eh_frame, may be present in the object file
+       with default target, but not with bpf target.
+
+     - The default target may turn a C switch statement into a switch table
+       lookup and jump operation. Since the switch table is placed
+       in the global readonly section, the bpf program will fail to load.
+       The bpf target does not support switch table optimization.
+       The clang option "-fno-jump-tables" can be used to disable
+       switch table generation.
+
+   You should use default target when:
+
+     - Your program includes a header file, e.g., ptrace.h, which eventually
+       pulls in some header files containing file scope host assembly codes.
+     - You can add "-fno-jump-tables" to work around the switch table issue.
+
+   Otherwise, you can use bpf target.
+
 Happy BPF hacking!

+============
+
+A mount option is available to create a serverless mount that is only usable

+
+	mount -t afs none /afs -o dyn
+
+This creates a mount that just has an empty directory at the root.  Attempting

 Remote Controller core
 ~~~~~~~~~~~~~~~~~~~~~~
 
+The remote controller core implements infrastructure to receive and send
+remote controller keyboard keystrokes and mouse events.
+
+Every time a key is pressed on a remote controller, a scan code is produced.
+Also, on most hardware, keeping a key pressed for more than a few dozens of
+milliseconds produce a repeat key event. That's somewhat similar to what
+a normal keyboard or mouse is handled internally on Linux\ [#f1]_. So, the
+remote controller core is implemented on the top of the linux input/evdev
+interface.
+
+.. [#f1]
+
+   The main difference is that, on keyboard events, the keyboard controller
+   produces one event for a key press and another one for key release. On
+   infrared-based remote controllers, there's no key release event. Instead,
+   an extra code is produced to indicate key repeats.
+
+However, most of the remote controllers use infrared (IR) to transmit signals.
+As there are several protocols used to modulate infrared signals, one
+important part of the core is dedicated to adjust the driver and the core
+system to support the infrared protocol used by the emitter.
+
+The infrared transmission is done by blinking a infrared emitter using a
+carrier. The carrier can be switched on or off by the IR transmitter
+hardware. When the carrier is switched on, it is called *PULSE*.
+When the carrier is switched off, it is called *SPACE*.
+
+In other words, a typical IR transmission can be viewed as a sequence of
+*PULSE* and *SPACE* events, each with a given duration.
+
+The carrier parameters (frequency, duty cycle) and the intervals for
+*PULSE* and *SPACE* events depend on the protocol.
+For example, the NEC protocol uses a carrier of 38kHz, and transmissions
+start with a 9ms *PULSE* and a 4.5ms SPACE. It then transmits 16 bits of
+scan code, being 8 bits for address (usually it is a fixed number for a
+given remote controller), followed by 8 bits of code. A bit "1" is modulated
+with 560µs *PULSE* followed by 1690µs *SPACE* and a bit "0"  is modulated
+with 560µs *PULSE* followed by 560µs *SPACE*.
+
+At receiver, a simple low-pass filter can be used to convert the received
+signal in a sequence of *PULSE/SPACE* events, filtering out the carrier
+frequency. Due to that, the receiver doesn't care about the carrier's
+actual frequency parameters: all it has to do is to measure the amount
+of time it receives *PULSE/SPACE* events.
+So, a simple IR receiver hardware will just provide a sequence of timings
+for those events to the Kernel. The drivers for hardware with such kind of
+receivers are identified by  ``RC_DRIVER_IR_RAW``, as defined by
+:c:type:`rc_driver_type`\ [#f2]_. Other hardware come with a
+microcontroller that decode the *PULSE/SPACE* sequence and return scan
+codes to the Kernel. Such kind of receivers are identified
+by ``RC_DRIVER_SCANCODE``.
+
+.. [#f2]
+
+   The RC core also supports devices that have just IR emitters,
+   without any receivers. Right now, all such devices work only in
+   raw TX mode. Such kind of hardware is identified as
+   ``RC_DRIVER_IR_RAW_TX``.
+
+When the RC core receives events produced by ``RC_DRIVER_IR_RAW`` IR
+receivers, it needs to decode the IR protocol, in order to obtain the
+corresponding scan code. The protocols supported by the RC core are
+defined at enum :c:type:`rc_proto`.
+
+When the RC code receives a scan code (either directly, by a driver
+of the type ``RC_DRIVER_SCANCODE``, or via its IR decoders), it needs
+to convert into a Linux input event code. This is done via a mapping
+table.
+
+The Kernel has support for mapping tables available on most media
+devices. It also supports loading a table in runtime, via some
+sysfs nodes. See the :ref:`RC userspace API <Remote_controllers_Intro>`
+for more details.

 The V4L2 events provide a generic way to pass events to user space.
 The driver must use :c:type:`v4l2_fh` to be able to support V4L2 events.
 
-Events are defined by a type and an optional ID. The ID may refer to a V4L2
-object such as a control ID. If unused, then the ID is 0.
+Events are subscribed per-filehandle. An event specification consists of a
+``type`` and is optionally associated with an object identified through the
+``id`` field. If unused, then the ``id`` is 0. So an event is uniquely
+identified by the ``(type, id)`` tuple.
 
-When the user subscribes to an event the driver will allocate a number of
-kevent structs for that event. So every (type, ID) event tuple will have
-its own set of kevent structs. This guarantees that if a driver is generating
-lots of events of one type in a short time, then that will not overwrite
-events of another type.
+The :c:type:`v4l2_fh` struct has a list of subscribed events on its
+``subscribed`` field.
 
-But if you get more events of one type than the number of kevents that were
-reserved, then the oldest event will be dropped and the new one added.
+When the user subscribes to an event, a :c:type:`v4l2_subscribed_event`
+struct is added to :c:type:`v4l2_fh`\ ``.subscribed``, one for every
+subscribed event.
+
+Each :c:type:`v4l2_subscribed_event` struct ends with a
+:c:type:`v4l2_kevent` ringbuffer, with the size given by the caller
+of :c:func:`v4l2_event_subscribe`. This ringbuffer is used to store any events
+raised by the driver.
+
+So every ``(type, ID)`` event tuple will have its own
+:c:type:`v4l2_kevent` ringbuffer. This guarantees that if a driver is
+generating lots of events of one type in a short time, then that will
+not overwrite events of another type.
+
+But if you get more events of one type than the size of the
+:c:type:`v4l2_kevent` ringbuffer, then the oldest event will be dropped
+and the new one added.
+
+The :c:type:`v4l2_kevent` struct links into the ``available``
+list of the :c:type:`v4l2_fh` struct so :ref:`VIDIOC_DQEVENT` will
+know which event to dequeue first.
+
+Finally, if the event subscription is associated with a particular object
+such as a V4L2 control, then that object needs to know about that as well
+so that an event can be raised by that object. So the ``node`` field can
+be used to link the :c:type:`v4l2_subscribed_event` struct into a list of
+such objects.
+
+So to summarize:
+
+- struct :c:type:`v4l2_fh` has two lists: one of the ``subscribed`` events,
+  and one of the ``available`` events.
+
+- struct :c:type:`v4l2_subscribed_event` has a ringbuffer of raised
+  (pending) events of that particular type.
+
+- If struct :c:type:`v4l2_subscribed_event` is associated with a specific
+  object, then that object will have an internal list of
+  struct :c:type:`v4l2_subscribed_event` so it knows who subscribed an
+  event to that object.
 
 Furthermore, the internal struct :c:type:`v4l2_subscribed_event` has
 ``merge()`` and ``replace()`` callbacks which drivers can set. These
 callbacks are called when a new event is raised and there is no more room.
+
 The ``replace()`` callback allows you to replace the payload of the old event
 with that of the new event, merging any relevant data from the old payload
 into the new payload that replaces it. It is called when this event type has
-only one kevent struct allocated. The ``merge()`` callback allows you to merge
-the oldest event payload into that of the second-oldest event payload. It is
-called when there are two or more kevent structs allocated.
+a ringbuffer with size is one, i.e. only one event can be stored in the
+ringbuffer.
+
+The ``merge()`` callback allows you to merge the oldest event payload into
+that of the second-oldest event payload. It is called when
+the ringbuffer has size is greater than one.
 
 This way no status information is lost, just the intermediate steps leading
 up to that state.

+    File descriptor returned by :ref:`open() <dmx_fopen>`.
+
+``argp``
+    Pointer to struct :c:type:`dmx_exportbuffer`.
+
+
+Description
+===========
+
+This ioctl is an extension to the memory mapping I/O method.
+It can be used to export a buffer as a DMABUF file at any time after
+buffers have been allocated with the :ref:`DMX_REQBUFS` ioctl.
+
+To export a buffer, applications fill struct :c:type:`dmx_exportbuffer`.
+Applications must set the ``index`` field. Valid index numbers
+range from zero to the number of buffers allocated with :ref:`DMX_REQBUFS`
+(struct :c:type:`dmx_requestbuffers` ``count``) minus one.
+Additional flags may be posted in the ``flags`` field. Refer to a manual
+for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
+and O_RDWR are supported.
+All other fields must be set to zero. In the
+case of multi-planar API, every plane is exported separately using
+multiple :ref:`DMX_EXPBUF` calls.
+
+After calling :ref:`DMX_EXPBUF` the ``fd`` field will be set by a
+driver, on success. This is a DMABUF file descriptor. The application may
+pass it to other DMABUF-aware devices. It is recommended to close a DMABUF
+file when it is no longer used to allow the associated memory to be reclaimed.
+
+
+Examples
+========
+
+
+.. code-block:: c
+
+    int buffer_export(int v4lfd, enum dmx_buf_type bt, int index, int *dmafd)
+    {
+	struct dmx_exportbuffer expbuf;
+
+	memset(&expbuf, 0, sizeof(expbuf));
+	expbuf.type = bt;
+	expbuf.index = index;
+	if (ioctl(v4lfd, DMX_EXPBUF, &expbuf) == -1) {
+	    perror("DMX_EXPBUF");
+	    return -1;
+	}
+
+	*dmafd = expbuf.fd;
+
+	return 0;
+    }
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+

+
+
+.. c:function:: void *mmap( void *start, size_t length, int prot, int flags, int fd, off_t offset )
+    :name: dmx-mmap
+
+Arguments
+=========
+
+``start``
+    Map the buffer to this address in the application's address space.
+    When the ``MAP_FIXED`` flag is specified, ``start`` must be a
+    multiple of the pagesize and mmap will fail when the specified
+    address cannot be used. Use of this option is discouraged;
+    applications should just specify a ``NULL`` pointer here.
+
+``length``
+    Length of the memory area to map. This must be a multiple of the
+    DVB packet length (188, on most drivers).
+
+``prot``
+    The ``prot`` argument describes the desired memory protection.
+    Regardless of the device type and the direction of data exchange it
+    should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
+    and write access to image buffers. Drivers should support at least
+    this combination of flags.
+
+``flags``
+    The ``flags`` parameter specifies the type of the mapped object,
+    mapping options and whether modifications made to the mapped copy of
+    the page are private to the process or are to be shared with other
+    references.
+
+    ``MAP_FIXED`` requests that the driver selects no other address than
+    the one specified. If the specified address cannot be used,
+    :ref:`mmap() <dmx-mmap>` will fail. If ``MAP_FIXED`` is specified,
+    ``start`` must be a multiple of the pagesize. Use of this option is
+    discouraged.
+
+    One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
+    ``MAP_SHARED`` allows applications to share the mapped memory with
+    other (e. g. child-) processes.
+
+    .. note::
+
+       The Linux Digital TV applications should not set the
+       ``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
+       flags.
+
+``fd``
+    File descriptor returned by :ref:`open() <dmx_fopen>`.
+
+``offset``
+    Offset of the buffer in device memory, as returned by
+    :ref:`DMX_QUERYBUF` ioctl.
+
+
+Description
+===========
+
+The :ref:`mmap() <dmx-mmap>` function asks to map ``length`` bytes starting at
+``offset`` in the memory of the device specified by ``fd`` into the
+application address space, preferably at address ``start``. This latter
+address is a hint only, and is usually specified as 0.
+
+Suitable length and offset parameters are queried with the
+:ref:`DMX_QUERYBUF` ioctl. Buffers must be allocated with the
+:ref:`DMX_REQBUFS` ioctl before they can be queried.
+
+To unmap buffers the :ref:`munmap() <dmx-munmap>` function is used.
+
+
+Return Value
+============
+
+On success :ref:`mmap() <dmx-mmap>` returns a pointer to the mapped buffer. On
+error ``MAP_FAILED`` (-1) is returned, and the ``errno`` variable is set
+appropriately. Possible error codes are:
+
+EBADF
+    ``fd`` is not a valid file descriptor.

+    Pointer to struct :c:type:`dmx_buffer`.
+
+
+Description
+===========
+
+Applications call the ``DMX_QBUF`` ioctl to enqueue an empty
+(capturing) or filled (output) buffer in the driver's incoming queue.
+The semantics depend on the selected I/O method.
+
+To enqueue a buffer applications set the ``index`` field. Valid index
+numbers range from zero to the number of buffers allocated with
+:ref:`DMX_REQBUFS` (struct :c:type:`dmx_requestbuffers` ``count``) minus
+one. The contents of the struct :c:type:`dmx_buffer` returned
+by a :ref:`DMX_QUERYBUF` ioctl will do as well.
+
+When ``DMX_QBUF`` is called with a pointer to this structure, it locks the
+memory pages of the buffer in physical memory, so they cannot be swapped
+out to disk. Buffers remain locked until dequeued, until the
+the device is closed.
+
+Applications call the ``DMX_DQBUF`` ioctl to dequeue a filled
+(capturing) buffer from the driver's outgoing queue. They just set the ``reserved`` field array to zero. When ``DMX_DQBUF`` is called with a
+pointer to this structure, the driver fills the remaining fields or
+returns an error code.
+
+By default ``DMX_DQBUF`` blocks when no buffer is in the outgoing
+queue. When the ``O_NONBLOCK`` flag was given to the
+:ref:`open() <dmx_fopen>` function, ``DMX_DQBUF`` returns
+immediately with an ``EAGAIN`` error code when no buffer is available.
+
+The struct :c:type:`dmx_buffer` structure is specified in
+:ref:`buffer`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EAGAIN
+    Non-blocking I/O has been selected using ``O_NONBLOCK`` and no
+    buffer was in the outgoing queue.
+
+EINVAL
+    The ``index`` is out of bounds, or no buffers have been allocated yet.
+
+EIO
+    ``DMX_DQBUF`` failed due to an internal error. Can also indicate
+    temporary problems like signal loss or CRC errors.

+
+``argp``
+    Pointer to struct :c:type:`dmx_requestbuffers`.
+
+Description
+===========
+
+This ioctl is used to initiate a memory mapped or DMABUF based demux I/O.
+
+Memory mapped buffers are located in device memory and must be allocated
+with this ioctl before they can be mapped into the application's address
+space. User buffers are allocated by applications themselves, and this
+ioctl is merely used to switch the driver into user pointer I/O mode and
+to setup some internal structures. Similarly, DMABUF buffers are
+allocated by applications through a device driver, and this ioctl only
+configures the driver into DMABUF I/O mode without performing any direct
+allocation.
+
+To allocate device buffers applications initialize all fields of the
+struct :c:type:`dmx_requestbuffers` structure. They set the  ``count`` field
+to the desired number of buffers,  and ``size`` to the size of each
+buffer.
+
+When the ioctl is called with a pointer to this structure, the driver will
+attempt to allocate the requested number of buffers and it stores the actual
+number allocated in the ``count`` field. The ``count`` can be smaller than the number requested, even zero, when the driver runs out of free memory. A larger
+number is also possible when the driver requires more buffers to
+function correctly. The actual allocated buffer size can is returned
+at ``size``, and can be smaller than what's requested.
+
+When this I/O method is not supported, the ioctl returns an ``EOPNOTSUPP``
+error code.
+
+Applications can call :ref:`DMX_REQBUFS` again to change the number of
+buffers, however this cannot succeed when any buffers are still mapped.
+A ``count`` value of zero frees all buffers, after aborting or finishing
+any DMA in progress.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EOPNOTSUPP
+    The  the requested I/O method is not supported.

 LIRC supports some modes of receiving and sending IR codes, as shown

+.. _lirc-scancode-flag-repeat:
+
+``LIRC_MODE_SCANCODE``
+
+    This mode is for both sending and receiving IR.
+
+    For transmitting (aka sending), create a ``struct lirc_scancode`` with
+    the desired scancode set in the ``scancode`` member, :c:type:`rc_proto`
+    set the IR protocol, and all other members set to 0. Write this struct to
+    the lirc device.
+
+    For receiving, you read ``struct lirc_scancode`` from the lirc device,
+    with ``scancode`` set to the received scancode and the IR protocol
+    :c:type:`rc_proto`. If the scancode maps to a valid key code, this is set
+    in the ``keycode`` field, else it is set to ``KEY_RESERVED``.
+
+    The ``flags`` can have ``LIRC_SCANCODE_FLAG_TOGGLE`` set if the toggle
+    bit is set in protocols that support it (e.g. rc-5 and rc-6), or
+    ``LIRC_SCANCODE_FLAG_REPEAT`` for when a repeat is received for protocols
+    that support it (e.g. nec).
+
+    In the Sanyo and NEC protocol, if you hold a button on remote, rather than
+    repeating the entire scancode, the remote sends a shorter message with
+    no scancode, which just means button is held, a "repeat". When this is
+    received, the ``LIRC_SCANCODE_FLAG_REPEAT`` is set and the scancode and
+    keycode is repeated.
+
+    With nec, there is no way to distinguish "button hold" from "repeatedly
+    pressing the same button". The rc-5 and rc-6 protocols have a toggle bit.
+    When a button is released and pressed again, the toggle bit is inverted.
+    If the toggle bit is set, the ``LIRC_SCANCODE_FLAG_TOGGLE`` is set.
+
+    The ``timestamp`` field is filled with the time nanoseconds

+UVC Payload Header Data
+
+
+Description
+===========
+
+This format describes standard UVC metadata, extracted from UVC packet headers
+and provided by the UVC driver through metadata video nodes. That data includes
+exact copies of the standard part of UVC Payload Header contents and auxiliary
+timing information, required for precise interpretation of timestamps, contained
+in those headers. See section "2.4.3.3 Video and Still Image Payload Headers" of
+the "UVC 1.5 Class specification" for details.
+
+Each UVC payload header can be between 2 and 12 bytes large. Buffers can
+contain multiple headers, if multiple such headers have been transmitted by the
+camera for the respective frame. However, the driver may drop headers when the
+buffer is full, when they contain no useful information (e.g. those without the
+SCR field or with that field identical to the previous header), or generally to
+perform rate limiting when the device sends a large number of headers.
+
+Each individual block contains the following fields:
+

+10-bit Bayer formats
+
+Description
+===========
+
+These four pixel formats are used by Intel IPU3 driver, they are raw
+sRGB / Bayer formats with 10 bits per sample with every 25 pixels packed
+to 32 bytes leaving 6 most significant bits padding in the last byte.
+The format is little endian.
+
+In other respects this format is similar to :ref:`V4L2-PIX-FMT-SRGGB10`.
+Below is an example of a small image in V4L2_PIX_FMT_IPU3_SBGGR10 format.
+
+**Byte Order.**
+Each cell is one byte.

+
+===========================
+Kernel Maintainer PGP guide
+===========================
+
+:Author: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
+
+This document is aimed at Linux kernel developers, and especially at
+subsystem maintainers. It contains a subset of information discussed in
+the more general "`Protecting Code Integrity`_" guide published by the
+Linux Foundation. Please read that document for more in-depth discussion
+on some of the topics mentioned in this guide.
+
+.. _`Protecting Code Integrity`: https://github.com/lfit/itpol/blob/master/protecting-code-integrity.md
+
+The role of PGP in Linux Kernel development
+===========================================
+
+PGP helps ensure the integrity of the code that is produced by the Linux
+kernel development community and, to a lesser degree, establish trusted
+communication channels between developers via PGP-signed email exchange.
+
+The Linux kernel source code is available in two main formats:
+
+- Distributed source repositories (git)
+- Periodic release snapshots (tarballs)
+
+Both git repositories and tarballs carry PGP signatures of the kernel
+developers who create official kernel releases. These signatures offer a
+cryptographic guarantee that downloadable versions made available via
+kernel.org or any other mirrors are identical to what these developers
+have on their workstations. To this end:
+
+- git repositories provide PGP signatures on all tags
+- tarballs provide detached PGP signatures with all downloads
+
+.. _devs_not_infra:
+
+Trusting the developers, not infrastructure
+-------------------------------------------
+
+Ever since the 2011 compromise of core kernel.org systems, the main
+operating principle of the Kernel Archives project has been to assume
+that any part of the infrastructure can be compromised at any time. For
+this reason, the administrators have taken deliberate steps to emphasize
+that trust must always be placed with developers and never with the code
+hosting infrastructure, regardless of how good the security practices
+for the latter may be.
+
+The above guiding principle is the reason why this guide is needed. We
+want to make sure that by placing trust into developers we do not simply
+shift the blame for potential future security incidents to someone else.
+The goal is to provide a set of guidelines developers can use to create
+a secure working environment and safeguard the PGP keys used to
+establish the integrity of the Linux kernel itself.
+
+.. _pgp_tools:
+
+PGP tools
+=========
+
+Use GnuPG v2
+------------
+
+Your distro should already have GnuPG installed by default, you just
+need to verify that you are using version 2.x and not the legacy 1.4
+release -- many distributions still package both, with the default
+``gpg`` command invoking GnuPG v.1. To check, run::
+
+    $ gpg --version | head -n1
+
+If you see ``gpg (GnuPG) 1.4.x``, then you are using GnuPG v.1. Try the
+``gpg2`` command (if you don't have it, you may need to install the
+gnupg2 package)::
+
+    $ gpg2 --version | head -n1
+
+If you see ``gpg (GnuPG) 2.x.x``, then you are good to go. This guide
+will assume you have the version 2.2 of GnuPG (or later). If you are
+using version 2.0 of GnuPG, then some of the commands in this guide will
+not work, and you should consider installing the latest 2.2 version of
+GnuPG. Versions of gnupg-2.1.11 and later should be compatible for the
+purposes of this guide as well.
+
+If you have both ``gpg`` and ``gpg2`` commands, you should make sure you
+are always using GnuPG v2, not the legacy version. You can enforce this
+by setting the appropriate alias::
+
+    $ alias gpg=gpg2
+
+You can put that in your ``.bashrc`` to make sure it's always the case.
+
+Configure gpg-agent options
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The GnuPG agent is a helper tool that will start automatically whenever
+you use the ``gpg`` command and run in the background with the purpose
+of caching the private key passphrase. There are two options you should
+know in order to tweak when the passphrase should be expired from cache:
+
+- ``default-cache-ttl`` (seconds): If you use the same key again before
+  the time-to-live expires, the countdown will reset for another period.
+  The default is 600 (10 minutes).
+- ``max-cache-ttl`` (seconds): Regardless of how recently you've used
+  the key since initial passphrase entry, if the maximum time-to-live
+  countdown expires, you'll have to enter the passphrase again. The
+  default is 30 minutes.
+
+If you find either of these defaults too short (or too long), you can
+edit your ``~/.gnupg/gpg-agent.conf`` file to set your own values::
+
+    # set to 30 minutes for regular ttl, and 2 hours for max ttl
+    default-cache-ttl 1800
+    max-cache-ttl 7200
+
+.. note::
+
+    It is no longer necessary to start gpg-agent manually at the
+    beginning of your shell session. You may want to check your rc files
+    to remove anything you had in place for older versions of GnuPG, as
+    it may not be doing the right thing any more.
+
+Set up a refresh cronjob
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+You will need to regularly refresh your keyring in order to get the
+latest changes on other people's public keys, which is best done with a
+daily cronjob::
+
+    @daily /usr/bin/gpg2 --refresh >/dev/null 2>&1
+
+Check the full path to your ``gpg`` or ``gpg2`` command and use the
+``gpg2`` command if regular ``gpg`` for you is the legacy GnuPG v.1.
+
+.. _master_key:
+
+Protect your master PGP key
+===========================
+
+This guide assumes that you already have a PGP key that you use for Linux
+kernel development purposes. If you do not yet have one, please see the
+"`Protecting Code Integrity`_" document mentioned earlier for guidance
+on how to create a new one.
+
+You should also make a new key if your current one is weaker than 2048 bits
+(RSA).
+
+Master key vs. Subkeys
+----------------------
+
+Subkeys are fully independent PGP keypairs that are tied to the "master"
+key using certifying key signatures (certificates). It is important to
+understand the following:
+
+1. There are no technical differences between the "master key" and "subkeys."
+2. At creation time, we assign functional limitations to each key by
+   giving it specific capabilities.
+3. A PGP key can have 4 capabilities:
+
+   - **[S]** key can be used for signing
+   - **[E]** key can be used for encryption
+   - **[A]** key can be used for authentication
+   - **[C]** key can be used for certifying other keys
+
+4. A single key may have multiple capabilities.
+5. A subkey is fully independent from the master key. A message
+   encrypted to a subkey cannot be decrypted with the master key. If you
+   lose your private subkey, it cannot be recreated from the master key
+   in any way.
+
+The key carrying the **[C]** (certify) capability is considered the
+"master" key because it is the only key that can be used to indicate
+relationship with other keys. Only the **[C]** key can be used to:
+
+- add or revoke other keys (subkeys) with S/E/A capabilities
+- add, change or revoke identities (uids) associated with the key
+- add or change the expiration date on itself or any subkey
+- sign other people's keys for web of trust purposes
+
+By default, GnuPG creates the following when generating new keys:
+
+- A master key carrying both Certify and Sign capabilities (**[SC]**)
+- A separate subkey with the Encryption capability (**[E]**)
+
+If you used the default parameters when generating your key, then that
+is what you will have. You can verify by running ``gpg --list-secret-keys``,
+for example::
+
+    sec   rsa2048 2018-01-23 [SC] [expires: 2020-01-23]
+          000000000000000000000000AAAABBBBCCCCDDDD
+    uid           [ultimate] Alice Dev <adev@kernel.org>
+    ssb   rsa2048 2018-01-23 [E] [expires: 2020-01-23]
+
+Any key carrying the **[C]** capability is your master key, regardless
+of any other capabilities it may have assigned to it.
+
+The long line under the ``sec`` entry is your key fingerprint --
+whenever you see ``[fpr]`` in the examples below, that 40-character
+string is what it refers to.
+
+Ensure your passphrase is strong
+--------------------------------
+
+GnuPG uses passphrases to encrypt your private keys before storing them on
+disk. This way, even if your ``.gnupg`` directory is leaked or stolen in
+its entirety, the attackers cannot use your private keys without first
+obtaining the passphrase to decrypt them.
+
+It is absolutely essential that your private keys are protected by a
+strong passphrase. To set it or change it, use::
+
+    $ gpg --change-passphrase [fpr]
+
+Create a separate Signing subkey
+--------------------------------
+
+Our goal is to protect your master key by moving it to offline media, so
+if you only have a combined **[SC]** key, then you should create a separate
+signing subkey::
+
+    $ gpg --quick-add-key [fpr] ed25519 sign
+
+Remember to tell the keyservers about this change, so others can pull down
+your new subkey::
+
+    $ gpg --send-key [fpr]
+
+.. note:: ECC support in GnuPG
+
+    GnuPG 2.1 and later has full support for Elliptic Curve
+    Cryptography, with ability to combine ECC subkeys with traditional
+    RSA master keys. The main upside of ECC cryptography is that it is
+    much faster computationally and creates much smaller signatures when
+    compared byte for byte with 2048+ bit RSA keys. Unless you plan on
+    using a smartcard device that does not support ECC operations, we
+    recommend that you create an ECC signing subkey for your kernel
+    work.
+
+    If for some reason you prefer to stay with RSA subkeys, just replace
+    "ed25519" with "rsa2048" in the above command.
+
+
+Back up your master key for disaster recovery
+---------------------------------------------
+
+The more signatures you have on your PGP key from other developers, the
+more reasons you have to create a backup version that lives on something
+other than digital media, for disaster recovery reasons.
+
+The best way to create a printable hardcopy of your private key is by
+using the ``paperkey`` software written for this very purpose. See ``man
+paperkey`` for more details on the output format and its benefits over
+other solutions. Paperkey should already be packaged for most
+distributions.
+
+Run the following command to create a hardcopy backup of your private
+key::
+
+    $ gpg --export-secret-key [fpr] | paperkey -o /tmp/key-backup.txt
+
+Print out that file (or pipe the output straight to lpr), then take a
+pen and write your passphrase on the margin of the paper. **This is
+strongly recommended** because the key printout is still encrypted with
+that passphrase, and if you ever change it you will not remember what it
+used to be when you had created the backup -- *guaranteed*.
+
+Put the resulting printout and the hand-written passphrase into an envelope
+and store in a secure and well-protected place, preferably away from your
+home, such as your bank vault.
+
+.. note::
+
+    Your printer is probably no longer a simple dumb device connected to
+    your parallel port, but since the output is still encrypted with
+    your passphrase, printing out even to "cloud-integrated" modern
+    printers should remain a relatively safe operation. One option is to
+    change the passphrase on your master key immediately after you are
+    done with paperkey.
+
+Back up your whole GnuPG directory
+----------------------------------
+
+.. warning::
+
+    **!!!Do not skip this step!!!**
+
+It is important to have a readily available backup of your PGP keys
+should you need to recover them. This is different from the
+disaster-level preparedness we did with ``paperkey``. You will also rely
+on these external copies whenever you need to use your Certify key --
+such as when making changes to your own key or signing other people's
+keys after conferences and summits.
+
+Start by getting a small USB "thumb" drive (preferably two!) that you
+will use for backup purposes. You will need to encrypt them using LUKS
+-- refer to your distro's documentation on how to accomplish this.
+
+For the encryption passphrase, you can use the same one as on your
+master key.
+
+Once the encryption process is over, re-insert the USB drive and make
+sure it gets properly mounted. Copy your entire ``.gnupg`` directory
+over to the encrypted storage::
+
+    $ cp -a ~/.gnupg /media/disk/foo/gnupg-backup
+
+You should now test to make sure everything still works::
+
+    $ gpg --homedir=/media/disk/foo/gnupg-backup --list-key [fpr]
+
+If you don't get any errors, then you should be good to go. Unmount the
+USB drive, distinctly label it so you don't blow it away next time you
+need to use a random USB drive, and put in a safe place -- but not too
+far away, because you'll need to use it every now and again for things
+like editing identities, adding or revoking subkeys, or signing other
+people's keys.
+
+Remove the master key from  your homedir
+----------------------------------------
+
+The files in our home directory are not as well protected as we like to
+think.  They can be leaked or stolen via many different means:
+
+- by accident when making quick homedir copies to set up a new workstation
+- by systems administrator negligence or malice
+- via poorly secured backups
+- via malware in desktop apps (browsers, pdf viewers, etc)
+- via coercion when crossing international borders
+
+Protecting your key with a good passphrase greatly helps reduce the risk
+of any of the above, but passphrases can be discovered via keyloggers,
+shoulder-surfing, or any number of other means. For this reason, the
+recommended setup is to remove your master key from your home directory
+and store it on offline storage.
+
+.. warning::
+
+    Please see the previous section and make sure you have backed up
+    your GnuPG directory in its entirety. What we are about to do will
+    render your key useless if you do not have a usable backup!
+
+First, identify the keygrip of your master key::
+
+    $ gpg --with-keygrip --list-key [fpr]
+
+The output will be something like this::
+
+    pub   rsa2048 2018-01-24 [SC] [expires: 2020-01-24]
+          000000000000000000000000AAAABBBBCCCCDDDD
+          Keygrip = 1111000000000000000000000000000000000000
+    uid           [ultimate] Alice Dev <adev@kernel.org>
+    sub   rsa2048 2018-01-24 [E] [expires: 2020-01-24]
+          Keygrip = 2222000000000000000000000000000000000000
+    sub   ed25519 2018-01-24 [S]
+          Keygrip = 3333000000000000000000000000000000000000
+
+Find the keygrip entry that is beneath the ``pub`` line (right under the
+master key fingerprint). This will correspond directly to a file in your
+``~/.gnupg`` directory::
+
+    $ cd ~/.gnupg/private-keys-v1.d
+    $ ls
+    1111000000000000000000000000000000000000.key
+    2222000000000000000000000000000000000000.key
+    3333000000000000000000000000000000000000.key
+
+All you have to do is simply remove the .key file that corresponds to
+the master keygrip::
+
+    $ cd ~/.gnupg/private-keys-v1.d
+    $ rm 1111000000000000000000000000000000000000.key
+
+Now, if you issue the ``--list-secret-keys`` command, it will show that
+the master key is missing (the ``#`` indicates it is not available)::
+
+    $ gpg --list-secret-keys
+    sec#  rsa2048 2018-01-24 [SC] [expires: 2020-01-24]
+          000000000000000000000000AAAABBBBCCCCDDDD
+    uid           [ultimate] Alice Dev <adev@kernel.org>
+    ssb   rsa2048 2018-01-24 [E] [expires: 2020-01-24]
+    ssb   ed25519 2018-01-24 [S]
+
+You should also remove any ``secring.gpg`` files in the ``~/.gnupg``
+directory, which are left over from earlier versions of GnuPG.
+
+If you don't have the "private-keys-v1.d" directory
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you do not have a ``~/.gnupg/private-keys-v1.d`` directory, then your
+secret keys are still stored in the legacy ``secring.gpg`` file used by
+GnuPG v1. Making any changes to your key, such as changing the
+passphrase or adding a subkey, should automatically convert the old
+``secring.gpg`` format to use ``private-keys-v1.d`` instead.
+
+Once you get that done, make sure to delete the obsolete ``secring.gpg``
+file, which still contains your private keys.
+
+.. _smartcards:
+
+Move the subkeys to a dedicated crypto device
+=============================================
+
+Even though the master key is now safe from being leaked or stolen, the
+subkeys are still in your home directory. Anyone who manages to get
+their hands on those will be able to decrypt your communication or fake
+your signatures (if they know the passphrase). Furthermore, each time a
+GnuPG operation is performed, the keys are loaded into system memory and
+can be stolen from there by sufficiently advanced malware (think
+Meltdown and Spectre).
+
+The best way to completely protect your keys is to move them to a
+specialized hardware device that is capable of smartcard operations.
+
+The benefits of smartcards
+--------------------------
+
+A smartcard contains a cryptographic chip that is capable of storing
+private keys and performing crypto operations directly on the card
+itself. Because the key contents never leave the smartcard, the
+operating system of the computer into which you plug in the hardware
+device is not able to retrieve the private keys themselves. This is very
+different from the encrypted USB storage device we used earlier for
+backup purposes -- while that USB device is plugged in and mounted, the
+operating system is able to access the private key contents.
+
+Using external encrypted USB media is not a substitute to having a
+smartcard-capable device.
+
+Available smartcard devices
+---------------------------
+
+Unless all your laptops and workstations have smartcard readers, the
+easiest is to get a specialized USB device that implements smartcard
+functionality.  There are several options available:
+
+- `Nitrokey Start`_: Open hardware and Free Software, based on FSI
+  Japan's `Gnuk`_. Offers support for ECC keys, but fewest security
+  features (such as resistance to tampering or some side-channel
+  attacks).
+- `Nitrokey Pro`_: Similar to the Nitrokey Start, but more
+  tamper-resistant and offers more security features, but no ECC
+  support.
+- `Yubikey 4`_: proprietary hardware and software, but cheaper than
+  Nitrokey Pro and comes available in the USB-C form that is more useful
+  with newer laptops. Offers additional security features such as FIDO
+  U2F, but no ECC.
+
+`LWN has a good review`_ of some of the above models, as well as several
+others. If you want to use ECC keys, your best bet among commercially
+available devices is the Nitrokey Start.

+
+Configure your smartcard device
+-------------------------------
+
+Your smartcard device should Just Work (TM) the moment you plug it into
+any modern Linux workstation. You can verify it by running::
+
+    $ gpg --card-status
+
+If you see full smartcard details, then you are good to go.
+Unfortunately, troubleshooting all possible reasons why things may not
+be working for you is way beyond the scope of this guide. If you are
+having trouble getting the card to work with GnuPG, please seek help via
+usual support channels.
+
+To configure your smartcard, you will need to use the GnuPG menu system, as
+there are no convenient command-line switches::
+
+    $ gpg --card-edit
+    [...omitted...]
+    gpg/card> admin
+    Admin commands are allowed
+    gpg/card> passwd
+
+You should set the user PIN (1), Admin PIN (3), and the Reset Code (4).
+Please make sure to record and store these in a safe place -- especially
+the Admin PIN and the Reset Code (which allows you to completely wipe
+the smartcard).  You so rarely need to use the Admin PIN, that you will
+inevitably forget what it is if you do not record it.
+
+Getting back to the main card menu, you can also set other values (such
+as name, sex, login data, etc), but it's not necessary and will
+additionally leak information about your smartcard should you lose it.
+
+.. note::
+
+    Despite having the name "PIN", neither the user PIN nor the admin
+    PIN on the card need to be numbers.
+
+Move the subkeys to your smartcard
+----------------------------------
+
+Exit the card menu (using "q") and save all changes. Next, let's move
+your subkeys onto the smartcard. You will need both your PGP key
+passphrase and the admin PIN of the card for most operations::
+
+    $ gpg --edit-key [fpr]
+
+    Secret subkeys are available.
+
+    pub  rsa2048/AAAABBBBCCCCDDDD
+         created: 2018-01-23  expires: 2020-01-23  usage: SC
+         trust: ultimate      validity: ultimate
+    ssb  rsa2048/1111222233334444
+         created: 2018-01-23  expires: never       usage: E
+    ssb  ed25519/5555666677778888
+         created: 2017-12-07  expires: never       usage: S
+    [ultimate] (1). Alice Dev <adev@kernel.org>
+
+    gpg>
+
+Using ``--edit-key`` puts us into the menu mode again, and you will
+notice that the key listing is a little different. From here on, all
+commands are done from inside this menu mode, as indicated by ``gpg>``.
+
+First, let's select the key we'll be putting onto the card -- you do
+this by typing ``key 1`` (it's the first one in the listing, the **[E]**
+subkey)::
+
+    gpg> key 1
+
+In the output, you should now see ``ssb*`` on the **[E]** key. The ``*``
+indicates which key is currently "selected." It works as a *toggle*,
+meaning that if you type ``key 1`` again, the ``*`` will disappear and
+the key will not be selected any more.
+
+Now, let's move that key onto the smartcard::
+
+    gpg> keytocard
+    Please select where to store the key:
+       (2) Encryption key
+    Your selection? 2
+
+Since it's our **[E]** key, it makes sense to put it into the Encryption
+slot.  When you submit your selection, you will be prompted first for
+your PGP key passphrase, and then for the admin PIN. If the command
+returns without an error, your key has been moved.
+
+**Important**: Now type ``key 1`` again to unselect the first key, and
+``key 2`` to select the **[S]** key::
+
+    gpg> key 1
+    gpg> key 2
+    gpg> keytocard
+    Please select where to store the key:
+       (1) Signature key
+       (3) Authentication key
+    Your selection? 1
+
+You can use the **[S]** key both for Signature and Authentication, but
+we want to make sure it's in the Signature slot, so choose (1). Once
+again, if your command returns without an error, then the operation was
+successful::
+
+    gpg> q
+    Save changes? (y/N) y
+
+Saving the changes will delete the keys you moved to the card from your
+home directory (but it's okay, because we have them in our backups
+should we need to do this again for a replacement smartcard).
+
+Verifying that the keys were moved
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you perform ``--list-secret-keys`` now, you will see a subtle
+difference in the output::
+
+    $ gpg --list-secret-keys
+    sec#  rsa2048 2018-01-24 [SC] [expires: 2020-01-24]
+          000000000000000000000000AAAABBBBCCCCDDDD
+    uid           [ultimate] Alice Dev <adev@kernel.org>
+    ssb>  rsa2048 2018-01-24 [E] [expires: 2020-01-24]
+    ssb>  ed25519 2018-01-24 [S]
+
+The ``>`` in the ``ssb>`` output indicates that the subkey is only
+available on the smartcard. If you go back into your secret keys
+directory and look at the contents there, you will notice that the
+``.key`` files there have been replaced with stubs::
+
+    $ cd ~/.gnupg/private-keys-v1.d
+    $ strings *.key | grep 'private-key'
+
+The output should contain ``shadowed-private-key`` to indicate that
+these files are only stubs and the actual content is on the smartcard.
+
+Verifying that the smartcard is functioning
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To verify that the smartcard is working as intended, you can create a
+signature::
+
+    $ echo "Hello world" | gpg --clearsign > /tmp/test.asc
+    $ gpg --verify /tmp/test.asc
+
+This should ask for your smartcard PIN on your first command, and then
+show "Good signature" after you run ``gpg --verify``.
+
+Congratulations, you have successfully made it extremely difficult to
+steal your digital developer identity!
+
+Other common GnuPG operations
+-----------------------------
+
+Here is a quick reference for some common operations you'll need to do
+with your PGP key.
+
+Mounting your master key offline storage
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You will need your master key for any of the operations below, so you
+will first need to mount your backup offline storage and tell GnuPG to
+use it::
+
+    $ export GNUPGHOME=/media/disk/foo/gnupg-backup
+    $ gpg --list-secret-keys
+
+You want to make sure that you see ``sec`` and not ``sec#`` in the
+output (the ``#`` means the key is not available and you're still using
+your regular home directory location).
+
+Extending key expiration date
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The master key has the default expiration date of 2 years from the date
+of creation. This is done both for security reasons and to make obsolete
+keys eventually disappear from keyservers.
+
+To extend the expiration on your key by a year from current date, just
+run::
+
+    $ gpg --quick-set-expire [fpr] 1y
+
+You can also use a specific date if that is easier to remember (e.g.
+your birthday, January 1st, or Canada Day)::
+
+    $ gpg --quick-set-expire [fpr] 2020-07-01
+
+Remember to send the updated key back to keyservers::
+
+    $ gpg --send-key [fpr]
+
+Updating your work directory after any changes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After you make any changes to your key using the offline storage, you will
+want to import these changes back into your regular working directory::
+
+    $ gpg --export | gpg --homedir ~/.gnupg --import
+    $ unset GNUPGHOME
+
+
+Using PGP with Git
+==================
+
+One of the core features of Git is its decentralized nature -- once a
+repository is cloned to your system, you have full history of the
+project, including all of its tags, commits and branches. However, with
+hundreds of cloned repositories floating around, how does anyone verify
+that their copy of linux.git has not been tampered with by a malicious
+third party?
+
+Or what happens if a backdoor is discovered in the code and the "Author"
+line in the commit says it was done by you, while you're pretty sure you
+had `nothing to do with it`_?
+
+To address both of these issues, Git introduced PGP integration. Signed
+tags prove the repository integrity by assuring that its contents are
+exactly the same as on the workstation of the developer who created the
+tag, while signed commits make it nearly impossible for someone to
+impersonate you without having access to your PGP keys.
+
+.. _`nothing to do with it`: https://github.com/jayphelps/git-blame-someone-else
+
+Configure git to use your PGP key
+---------------------------------
+
+If you only have one secret key in your keyring, then you don't really
+need to do anything extra, as it becomes your default key.  However, if
+you happen to have multiple secret keys, you can tell git which key
+should be used (``[fpr]`` is the fingerprint of your key)::
+
+    $ git config --global user.signingKey [fpr]
+
+**IMPORTANT**: If you have a distinct ``gpg2`` command, then you should
+tell git to always use it instead of the legacy ``gpg`` from version 1::
+
+    $ git config --global gpg.program gpg2
+
+How to work with signed tags
+----------------------------
+
+To create a signed tag, simply pass the ``-s`` switch to the tag
+command::
+
+    $ git tag -s [tagname]
+
+Our recommendation is to always sign git tags, as this allows other
+developers to ensure that the git repository they are pulling from has
+not been maliciously altered.
+
+How to verify signed tags
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To verify a signed tag, simply use the ``verify-tag`` command::
+
+    $ git verify-tag [tagname]
+
+If you are pulling a tag from another fork of the project repository,
+git should automatically verify the signature at the tip you're pulling
+and show you the results during the merge operation::
+
+    $ git pull [url] tags/sometag
+
+The merge message will contain something like this::
+
+    Merge tag 'sometag' of [url]
+
+    [Tag message]
+
+    # gpg: Signature made [...]
+    # gpg: Good signature from [...]
+
+If you are verifying someone else's git tag, then you will need to
+import their PGP key. Please refer to the
+":ref:`verify_identities`" section below.
+
+Configure git to always sign annotated tags
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Chances are, if you're creating an annotated tag, you'll want to sign
+it. To force git to always sign annotated tags, you can set a global
+configuration option::
+
+    $ git config --global tag.forceSignAnnotated true
+
+How to work with signed commits
+-------------------------------
+
+It is easy to create signed commits, but it is much more difficult to
+use them in Linux kernel development, since it relies on patches sent to
+the mailing list, and this workflow does not preserve PGP commit
+signatures. Furthermore, when rebasing your repository to match
+upstream, even your own PGP commit signatures will end up discarded. For
+this reason, most kernel developers don't bother signing their commits
+and will ignore signed commits in any external repositories that they
+rely upon in their work.
+
+However, if you have your working git tree publicly available at some
+git hosting service (kernel.org, infradead.org, ozlabs.org, or others),
+then the recommendation is that you sign all your git commits even if
+upstream developers do not directly benefit from this practice.
+
+We recommend this for the following reasons:
+
+1. Should there ever be a need to perform code forensics or track code
+   provenance, even externally maintained trees carrying PGP commit
+   signatures will be valuable for such purposes.
+2. If you ever need to re-clone your local repository (for example,
+   after a disk failure), this lets you easily verify the repository
+   integrity before resuming your work.
+3. If someone needs to cherry-pick your commits, this allows them to
+   quickly verify their integrity before applying them.
+
+Creating signed commits
+~~~~~~~~~~~~~~~~~~~~~~~
+
+To create a signed commit, you just need to pass the ``-S`` flag to the
+``git commit`` command (it's capital ``-S`` due to collision with
+another flag)::
+
+    $ git commit -S
+
+Configure git to always sign commits
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can tell git to always sign commits::
+
+    git config --global commit.gpgSign true
+
+.. note::
+
+    Make sure you configure ``gpg-agent`` before you turn this on.
+
+.. _verify_identities:
+
+How to verify kernel developer identities
+=========================================
+
+Signing tags and commits is easy, but how does one go about verifying
+that the key used to sign something belongs to the actual kernel
+developer and not to a malicious imposter?
+
+Configure auto-key-retrieval using WKD and DANE
+-----------------------------------------------
+
+If you are not already someone with an extensive collection of other
+developers' public keys, then you can jumpstart your keyring by relying
+on key auto-discovery and auto-retrieval. GnuPG can piggyback on other
+delegated trust technologies, namely DNSSEC and TLS, to get you going if
+the prospect of starting your own Web of Trust from scratch is too
+daunting.
+
+Add the following to your ``~/.gnupg/gpg.conf``::
+
+    auto-key-locate wkd,dane,local
+    auto-key-retrieve
+
+DNS-Based Authentication of Named Entities ("DANE") is a method for
+publishing public keys in DNS and securing them using DNSSEC signed
+zones. Web Key Directory ("WKD") is the alternative method that uses
+https lookups for the same purpose. When using either DANE or WKD for
+looking up public keys, GnuPG will validate DNSSEC or TLS certificates,
+respectively, before adding auto-retrieved public keys to your local
+keyring.
+
+Kernel.org publishes the WKD for all developers who have kernel.org
+accounts. Once you have the above changes in your ``gpg.conf``, you can
+auto-retrieve the keys for Linus Torvalds and Greg Kroah-Hartman (if you
+don't already have them)::
+
+    $ gpg --locate-keys torvalds@kernel.org gregkh@kernel.org
+
+If you have a kernel.org account, then you should `add the kernel.org
+UID to your key`_ to make WKD more useful to other kernel developers.
+
+.. _`add the kernel.org UID to your key`: https://korg.wiki.kernel.org/userdoc/mail#adding_a_kernelorg_uid_to_your_pgp_key
+
+Web of Trust (WOT) vs. Trust on First Use (TOFU)
+------------------------------------------------
+
+PGP incorporates a trust delegation mechanism known as the "Web of
+Trust." At its core, this is an attempt to replace the need for
+centralized Certification Authorities of the HTTPS/TLS world. Instead of
+various software makers dictating who should be your trusted certifying
+entity, PGP leaves this responsibility to each user.
+
+Unfortunately, very few people understand how the Web of Trust works.
+While it remains an important aspect of the OpenPGP specification,
+recent versions of GnuPG (2.2 and above) have implemented an alternative
+mechanism called "Trust on First Use" (TOFU). You can think of TOFU as
+"the SSH-like approach to trust." With SSH, the first time you connect
+to a remote system, its key fingerprint is recorded and remembered. If
+the key changes in the future, the SSH client will alert you and refuse
+to connect, forcing you to make a decision on whether you choose to
+trust the changed key or not. Similarly, the first time you import
+someone's PGP key, it is assumed to be valid. If at any point in the
+future GnuPG comes across another key with the same identity, both the
+previously imported key and the new key will be marked as invalid and
+you will need to manually figure out which one to keep.
+
+We recommend that you use the combined TOFU+PGP trust model (which is
+the new default in GnuPG v2). To set it, add (or modify) the
+``trust-model`` setting in ``~/.gnupg/gpg.conf``::
+
+    trust-model tofu+pgp
+
+How to use keyservers (more) safely
+-----------------------------------
+
+If you get a "No public key" error when trying to validate someone's
+tag, then you should attempt to lookup that key using a keyserver. It is
+important to keep in mind that there is absolutely no guarantee that the
+key you retrieve from PGP keyservers belongs to the actual person --
+that much is by design. You are supposed to use the Web of Trust to
+establish key validity.
+
+How to properly maintain the Web of Trust is beyond the scope of this
+document, simply because doing it properly requires both effort and
+dedication that tends to be beyond the caring threshold of most human
+beings. Here are some shortcuts that will help you reduce the risk of
+importing a malicious key.
+
+First, let's say you've tried to run ``git verify-tag`` but it returned
+an error saying the key is not found::
+
+    $ git verify-tag sunxi-fixes-for-4.15-2
+    gpg: Signature made Sun 07 Jan 2018 10:51:55 PM EST
+    gpg:                using RSA key DA73759BF8619E484E5A3B47389A54219C0F2430
+    gpg:                issuer "wens@...org"
+    gpg: Can't check signature: No public key
+
+Let's query the keyserver for more info about that key fingerprint (the
+fingerprint probably belongs to a subkey, so we can't use it directly
+without finding out the ID of the master key it is associated with)::
+
+    $ gpg --search DA73759BF8619E484E5A3B47389A54219C0F2430
+    gpg: data source: hkp://keys.gnupg.net
+    (1) Chen-Yu Tsai <wens@...org>
+          4096 bit RSA key C94035C21B4F2AEB, created: 2017-03-14, expires: 2019-03-15
+    Keys 1-1 of 1 for "DA73759BF8619E484E5A3B47389A54219C0F2430".  Enter number(s), N)ext, or Q)uit > q
+
+Locate the ID of the master key in the output, in our example
+``C94035C21B4F2AEB``. Now display the key of Linus Torvalds that you
+have on your keyring::
+
+    $ gpg --list-key torvalds@kernel.org
+    pub   rsa2048 2011-09-20 [SC]
+          ABAF11C65A2970B130ABE3C479BE3E4300411886
+    uid           [ unknown] Linus Torvalds <torvalds@kernel.org>
+    sub   rsa2048 2011-09-20 [E]
+
+Next, open the `PGP pathfinder`_. In the "From" field, paste the key
+fingerprint of Linus Torvalds from the output above. In the "To" field,
+paste they key-id you found via ``gpg --search`` of the unknown key, and
+check the results:
+
+- `Finding paths to Linus`_
+
+If you get a few decent trust paths, then it's a pretty good indication
+that it is a valid key. You can add it to your keyring from the
+keyserver now::
+
+    $ gpg --recv-key C94035C21B4F2AEB
+
+This process is not perfect, and you are obviously trusting the
+administrators of the PGP Pathfinder service to not be malicious (in
+fact, this goes against :ref:`devs_not_infra`). However, if you
+do not carefully maintain your own web of trust, then it is a marked
+improvement over blindly trusting keyservers.

+ * registers are chosen by the compiler in $n form, allowing us to avoid using

+ *
+ * It also allows newer instructions (not implemented by the assembler) to be
+ * transparently implemented using assembler macros, instead of needing separate
+ * cases depending on toolchain support.
+ *
+ * Simple usage example:
+ * __asm__ __volatile__("parse_r __rt, %0\n\t"
+ *			".insn\n\t"
+ *			"# di    %0\n\t"

   link_notify callback when the pipeline is modified. It should be
   decided whether this feature is useful enough to make it generally
   available by exporting to v4l2-core.
+
+- The OF graph is walked at probe time to form the list of fwnodes to
+  be passed to v4l2_async_notifier_register(), starting from the IPU
+  CSI ports. And after all async subdevices have been bound,
+  v4l2_fwnode_parse_link() is used to form the media links between
+  the entities discovered by walking the OF graph.
+
+  While this approach allows support for arbitrary OF graphs, there
+  are some assumptions for this to work:
+
+  1. All port parent nodes reachable in the graph from the IPU CSI
+     ports bind to V4L2 async subdevice drivers.
+
+     If a device has mixed-use ports such as video plus audio, the
+     endpoints from the audio ports are followed to devices that must
+     bind to V4L2 subdevice drivers, and not for example, to an ALSA
+     driver or a non-V4L2 media driver. If the device were bound to
+     such a driver, imx-media would never get an async completion
+     notification because the device fwnode was added to the async
+     list, but the driver does not interface with the V4L2 async
+     framework.
+
+  2. Every port reachable in the graph is treated as a media pad,
+     owned by the V4L2 subdevice that is bound to the port's parent.
+
+     This presents problems for devices that don't make this port = pad
+     assumption. Examples are SMIAPP compatible cameras which define only
+     a single output port node, but which define multiple pads owned
+     by multiple subdevices (pixel-array, binner, scaler). Or video
+     decoders (entity function MEDIA_ENT_F_ATV_DECODER), which also define
+     only a single output port node, but define multiple pads for video,
+     VBI, and audio out.
+
+     A workaround at present is to set the port reg properties to
+     correspond to the media pad index that the port represents. A
+     possible long-term solution is to implement a subdev API that
+     maps a port id to a media pad index.
+
+  3. Every endpoint of a port reachable in the graph is treated as
+     a media link, between V4L2 subdevices that are bound to the
+     port parents of the local and remote endpoints.
+
+     Which means a port must not contain mixed-use endpoints, they
+     must all refer to media links between V4L2 subdevices.

-(The good news is ref-counting of lirc_zilog internal structures appears to be
-complete.  Testing has shown the cx18 module can be unloaded out from under
-irw + lircd + lirc_dev, with the /dev/lirc0 device node open, with no adverse
-effects.  The cx18 module could then be reloaded and irw properly began
-receiving button presses again and ir_send worked without error.)
-
-
-3. Bridge drivers, if able, should provide a chip reset() callback
-to lirc_zilog via struct IR_i2c_init_data.  cx18 and ivtv already have routines
-to perform Z8 chip resets via GPIO manipulations.  This would allow lirc_zilog
-to bring the chip back to normal when it hangs, in the same places the
-original lirc_pvr150 driver code does.  This is not strictly needed, so it
-is not required to move lirc_zilog out of staging.
-
-Note: Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed
-and installed on Hauppauge products.  When working on either module, developers
-must consider at least the following bridge drivers which mention an IR Rx unit
-at address 0x71 (indicative of a Z8):

- * Overview:
- *
- * Events are subscribed per-filehandle. An event specification consists of a
- * type and is optionally associated with an object identified through the
- * 'id' field. So an event is uniquely identified by the (type, id) tuple.
- *
- * The v4l2-fh struct has a list of subscribed events. The v4l2_subscribed_event
- * struct is added to that list, one for every subscribed event.
- *
- * Each v4l2_subscribed_event struct ends with an array of v4l2_kevent structs.
- * This array (ringbuffer, really) is used to store any events raised by the
- * driver. The v4l2_kevent struct links into the 'available' list of the
- * v4l2_fh struct so VIDIOC_DQEVENT will know which event to dequeue first.
- *
- * Finally, if the event subscription is associated with a particular object
- * such as a V4L2 control, then that object needs to know about that as well
- * so that an event can be raised by that object. So the 'node' field can
- * be used to link the v4l2_subscribed_event struct into a list of that
- * object.
- *
- * So to summarize:
- *
- * struct v4l2_fh has two lists: one of the subscribed events, and one of the
- * pending events.
- *
- * struct v4l2_subscribed_event has a ringbuffer of raised (pending) events of
- * that particular type.
- *
- * If struct v4l2_subscribed_event is associated with a specific object, then
- * that object will have an internal list of struct v4l2_subscribed_event so
- * it knows who subscribed an event to that object.
