+Part 0: Assumptions
+======================
+
+This document assumes the reader has basic knowledge in network drivers
+and in general interrupt moderation.
+
+
+Part I: Introduction
+======================
+
+Dynamic Interrupt Moderation (DIM) (in networking) refers to changing the
+interrupt moderation configuration of a channel in order to optimize packet
+processing. The mechanism includes an algorithm which decides if and how to
+change moderation parameters for a channel, usually by performing an analysis on
+runtime data sampled from the system. Net DIM is such a mechanism. In each
+iteration of the algorithm, it analyses a given sample of the data, compares it
+to the previous sample and if required, it can decide to change some of the
+interrupt moderation configuration fields. The data sample is composed of data
+bandwidth, the number of packets and the number of events. The time between
+samples is also measured. Net DIM compares the current and the previous data and
+returns an adjusted interrupt moderation configuration object. In some cases,
+the algorithm might decide not to change anything. The configuration fields are
+the minimum duration (microseconds) allowed between events and the maximum
+number of wanted packets per event. The Net DIM algorithm ascribes importance to
+increase bandwidth over reducing interrupt rate.
+
+
+Part II: The Net DIM Algorithm
+===============================
+
+Each iteration of the Net DIM algorithm follows these steps:
+1. Calculates new data sample.
+2. Compares it to previous sample.
+3. Makes a decision - suggests interrupt moderation configuration fields.
+4. Applies a schedule work function, which applies suggested configuration.
+
+The first two steps are straightforward, both the new and the previous data are
+supplied by the driver registered to Net DIM. The previous data is the new data
+supplied to the previous iteration. The comparison step checks the difference
+between the new and previous data and decides on the result of the last step.
+A step would result as "better" if bandwidth increases and as "worse" if
+bandwidth reduces. If there is no change in bandwidth, the packet rate is
+compared in a similar fashion - increase == "better" and decrease == "worse".
+In case there is no change in the packet rate as well, the interrupt rate is
+compared. Here the algorithm tries to optimize for lower interrupt rate so an
+increase in the interrupt rate is considered "worse" and a decrease is
+considered "better". Step #2 has an optimization for avoiding false results: it
+only considers a difference between samples as valid if it is greater than a
+certain percentage. Also, since Net DIM does not measure anything by itself, it
+assumes the data provided by the driver is valid.
+
+Step #3 decides on the suggested configuration based on the result from step #2
+and the internal state of the algorithm. The states reflect the "direction" of
+the algorithm: is it going left (reducing moderation), right (increasing
+moderation) or standing still. Another optimization is that if a decision
+to stay still is made multiple times, the interval between iterations of the
+algorithm would increase in order to reduce calculation overhead. Also, after
+"parking" on one of the most left or most right decisions, the algorithm may
+decide to verify this decision by taking a step in the other direction. This is
+done in order to avoid getting stuck in a "deep sleep" scenario. Once a
+decision is made, an interrupt moderation configuration is selected from
+the predefined profiles.
+
+The last step is to notify the registered driver that it should apply the
+suggested configuration. This is done by scheduling a work function, defined by
+the Net DIM API and provided by the registered driver.
+
+As you can see, Net DIM itself does not actively interact with the system. It
+would have trouble making the correct decisions if the wrong data is supplied to
+it and it would be useless if the work function would not apply the suggested
+configuration. This does, however, allow the registered driver some room for
+manoeuvre as it may provide partial data or ignore the algorithm suggestion
+under some conditions.
+
+
+Part III: Registering a Network Device to DIM
+==============================================
+
+Net DIM API exposes the main function net_dim(struct net_dim *dim,
+struct net_dim_sample end_sample). This function is the entry point to the Net
+DIM algorithm and has to be called every time the driver would like to check if
+it should change interrupt moderation parameters. The driver should provide two
+data structures: struct net_dim and struct net_dim_sample. Struct net_dim
+describes the state of DIM for a specific object (RX queue, TX queue,
+other queues, etc.). This includes the current selected profile, previous data
+samples, the callback function provided by the driver and more.
+Struct net_dim_sample describes a data sample, which will be compared to the
+data sample stored in struct net_dim in order to decide on the algorithm's next
+step. The sample should include bytes, packets and interrupts, measured by
+the driver.
+
+In order to use Net DIM from a networking driver, the driver needs to call the
+main net_dim() function. The recommended method is to call net_dim() on each
+interrupt. Since Net DIM has a built-in moderation and it might decide to skip
+iterations under certain conditions, there is no need to moderate the net_dim()
+calls as well. As mentioned above, the driver needs to provide an object of type
+struct net_dim to the net_dim() function call. It is advised for each entity
+using Net DIM to hold a struct net_dim as part of its data structure and use it
+as the main Net DIM API object. The struct net_dim_sample should hold the latest
+bytes, packets and interrupts count. No need to perform any calculations, just
+include the raw data.
+
+The net_dim() call itself does not return anything. Instead Net DIM relies on
+the driver to provide a callback function, which is called when the algorithm
+decides to make a change in the interrupt moderation parameters. This callback
+will be scheduled and run in a separate thread in order not to add overhead to
+the data flow. After the work is done, Net DIM algorithm needs to be set to
+the proper state in order to move to the next iteration.
+
+
+Part IV: Example
+=================
+
+The following code demonstrates how to register a driver to Net DIM. The actual
+usage is not complete but it should make the outline of the usage clear.
+
+my_driver.c:
+
+#include <linux/net_dim.h>
+
+/* Callback for net DIM to schedule on a decision to change moderation */
+void my_driver_do_dim_work(struct work_struct *work)
+{
+	/* Get struct net_dim from struct work_struct */
+	struct net_dim *dim = container_of(work, struct net_dim,
+					   work);
+	/* Do interrupt moderation related stuff */
+	...
+
+	/* Signal net DIM work is done and it should move to next iteration */
+	dim->state = NET_DIM_START_MEASURE;
+}
+
+/* My driver's interrupt handler */
+int my_driver_handle_interrupt(struct my_driver_entity *my_entity, ...)
+{
+	...
+	/* A struct to hold current measured data */
+	struct net_dim_sample dim_sample;
+	...
+	/* Initiate data sample struct with current data */
+	net_dim_sample(my_entity->events,
+		       my_entity->packets,
+		       my_entity->bytes,
+		       &dim_sample);
+	/* Call net DIM */
+	net_dim(&my_entity->dim, dim_sample);
+	...
+}
+
+/* My entity's initialization function (my_entity was already allocated) */
+int my_driver_init_my_entity(struct my_driver_entity *my_entity, ...)
+{
+	...
+	/* Initiate struct work_struct with my driver's callback function */
+	INIT_WORK(&my_entity->dim.work, my_driver_do_dim_work);
+	...
+}

+ * Before encoding a non-upper directory file handle from real layer N, we need
+ * to check if it will be possible to reconnect an overlay dentry from the real
+ * lower decoded dentry. This is done by following the overlay ancestry up to a
+ * "layer N connected" ancestor and verifying that all parents along the way are
+ * "layer N connectable". If an ancestor that is NOT "layer N connectable" is
+ * found, we need to copy up an ancestor, which is "layer N connectable", thus
+ * making that ancestor "layer N connected". For example:
+ *
+ * layer 1: /a
+ * layer 2: /a/b/c
+ *
+ * The overlay dentry /a is NOT "layer 2 connectable", because if dir /a is
+ * copied up and renamed, upper dir /a will be indexed by lower dir /a from
+ * layer 1. The dir /a from layer 2 will never be indexed, so the algorithm (*)
+ * in ovl_lookup_real_ancestor() will not be able to lookup a connected overlay
+ * dentry from the connected lower dentry /a/b/c.
+ *
+ * To avoid this problem on decode time, we need to copy up an ancestor of
+ * /a/b/c, which is "layer 2 connectable", on encode time. That ancestor is
+ * /a/b. After copy up (and index) of /a/b, it will become "layer 2 connected"
+ * and when the time comes to decode the file handle from lower dentry /a/b/c,
+ * ovl_lookup_real_ancestor() will find the indexed ancestor /a/b and decoding
+ * a connected overlay dentry will be accomplished.
+ *
+ * (*) the algorithm in ovl_lookup_real_ancestor() can be improved to lookup an
+ * entry /a in the lower layers above layer N and find the indexed dir /a from
+ * layer 1. If that improvement is made, then the check for "layer N connected"
+ * will need to verify there are no redirects in lower layers above N. In the
+ * example above, /a will be "layer 2 connectable". However, if layer 2 dir /a
+ * is a target of a layer 1 redirect, then /a will NOT be "layer 2 connectable":

+Motivation
+==========
+
+One of the nice things about network namespaces is that they allow one
+to easily create and test complex environments.
+
+Unfortunately, these namespaces can not be used with actual switching
+ASICs, as their ports can not be migrated to other network namespaces
+(NETIF_F_NETNS_LOCAL) and most of them probably do not support the
+L1-separation provided by namespaces.
+
+However, a similar kind of flexibility can be achieved by using VRFs and
+by looping the switch ports together. For example:
+
+                             br0
+                              +
+               vrf-h1         |           vrf-h2
+                 +        +---+----+        +
+                 |        |        |        |
+    192.0.2.1/24 +        +        +        + 192.0.2.2/24
+               swp1     swp2     swp3     swp4
+                 +        +        +        +
+                 |        |        |        |
+                 +--------+        +--------+
+
+The VRFs act as lightweight namespaces representing hosts connected to
+the switch.
+
+This approach for testing switch ASICs has several advantages over the
+traditional method that requires multiple physical machines, to name a
+few:
+
+1. Only the device under test (DUT) is being tested without noise from
+other system.
+
+2. Ability to easily provision complex topologies. Testing bridging
+between 4-ports LAGs or 8-way ECMP requires many physical links that are
+not always available. With the VRF-based approach one merely needs to
+loopback more ports.
+
+These tests are written with switch ASICs in mind, but they can be run
+on any Linux box using veth pairs to emulate physical loopbacks.
+
+Guidelines for Writing Tests
+============================
+
+o Where possible, reuse an existing topology for different tests instead
+  of recreating the same topology.
+o Where possible, IPv6 and IPv4 addresses shall conform to RFC 3849 and
+  RFC 5737, respectively.
+o Where possible, tests shall be written so that they can be reused by
+  multiple topologies and added to lib.sh.
+o Checks shall be added to lib.sh for any external dependencies.
+o Code shall be checked using ShellCheck [1] prior to submission.

+# Check that route PMTU values match expectations, and that initial device MTU

+#
+# Tests currently implemented:
+#
+# - pmtu_vti4_exception
+#	Set up vti tunnel on top of veth, with xfrm states and policies, in two
+#	namespaces with matching endpoints. Check that route exception is not
+#	created if link layer MTU is not exceeded, then exceed it and check that
+#	exception is created with the expected PMTU. The approach described
+#	below for IPv6 doesn't apply here, because, on IPv4, administrative MTU
+#	changes alone won't affect PMTU
+#
+# - pmtu_vti6_exception
+#	Set up vti6 tunnel on top of veth, with xfrm states and policies, in two
+#	namespaces with matching endpoints. Check that route exception is
+#	created by exceeding link layer MTU with ping to other endpoint. Then
+#	decrease and increase MTU of tunnel, checking that route exception PMTU
+#	changes accordingly
+#
+# - pmtu_vti4_default_mtu
+#	Set up vti4 tunnel on top of veth, in two namespaces with matching
+#	endpoints. Check that MTU assigned to vti interface is the MTU of the
+#	lower layer (veth) minus additional lower layer headers (zero, for veth)
+#	minus IPv4 header length
+#
+# - pmtu_vti6_default_mtu
+#	Same as above, for IPv6
+#
+# - pmtu_vti4_link_add_mtu
+#	Set up vti4 interface passing MTU value at link creation, check MTU is
+#	configured, and that link is not created with invalid MTU values
+#
+# - pmtu_vti6_link_add_mtu
+#	Same as above, for IPv6
+#
+# - pmtu_vti6_link_change_mtu
+#	Set up two dummy interfaces with different MTUs, create a vti6 tunnel
+#	and check that configured MTU is used on link creation and changes, and
+#	that MTU is properly calculated instead when MTU is not configured from

+OVERVIEW OF TDC EXECUTION
+-------------------------
+
+One run of tests is considered a "test suite" (this will be refined in the
+future).  A test suite has one or more test cases in it.
+
+A test case has four stages:
+
+  - setup
+  - execute
+  - verify
+  - teardown
+
+The setup and teardown stages can run zero or more commands.  The setup
+stage does some setup if the test needs it.  The teardown stage undoes
+the setup and returns the system to a "neutral" state so any other test
+can be run next.  These two stages require any commands run to return
+success, but do not otherwise verify the results.
+
+The execute and verify stages each run one command.  The execute stage
+tests the return code against one or more acceptable values.  The
+verify stage checks the return code for success, and also compares
+the stdout with a regular expression.
+
+Each of the commands in any stage will run in a shell instance.

+
+PLUGIN ARCHITECTURE
+-------------------
+
+There is now a plugin architecture, and some of the functionality that
+was in the tdc.py script has been moved into the plugins.
+
+The plugins are in the directory plugin-lib.  The are executed from
+directory plugins.  Put symbolic links from plugins to plugin-lib,
+and name them according to the order you want them to run.
+
+Example:
+
+bjb@bee:~/work/tc-testing$ ls -l plugins
+total 4
+lrwxrwxrwx  1 bjb  bjb    27 Oct  4 16:12 10-rootPlugin.py -> ../plugin-lib/rootPlugin.py
+lrwxrwxrwx  1 bjb  bjb    25 Oct 12 17:55 20-nsPlugin.py -> ../plugin-lib/nsPlugin.py
+-rwxr-xr-x  1 bjb  bjb     0 Sep 29 15:56 __init__.py
+
+The plugins are a subclass of TdcPlugin, defined in TdcPlugin.py and
+must be called "SubPlugin" so tdc can find them.  They are
+distinguished from each other in the python program by their module
+name.
+
+This base class supplies "hooks" to run extra functions.  These hooks are as follows:
+
+pre- and post-suite
+pre- and post-case
+pre- and post-execute stage
+adjust-command (runs in all stages and receives the stage name)
+
+The pre-suite hook receives the number of tests and an array of test ids.
+This allows you to dump out the list of skipped tests in the event of a
+failure during setup or teardown stage.
+
+The pre-case hook receives the ordinal number and test id of the current test.
+
+The adjust-command hook receives the stage id (see list below) and the
+full command to be executed.  This allows for last-minute adjustment
+of the command.
+
+The stages are identified by the following strings:
+
+  - pre  (pre-suite)
+  - setup
+  - command
+  - verify
+  - teardown
+  - post (post-suite)
+
+
+To write a plugin, you need to inherit from TdcPlugin in
+TdcPlugin.py.  To use the plugin, you have to put the
+implementation file in plugin-lib, and add a symbolic link to it from
+plugins.  It will be detected at run time and invoked at the
+appropriate times.  There are a few examples in the plugin-lib
+directory:
+
+  - rootPlugin.py:
+      implements the enforcement of running as root
+  - nsPlugin.py:
+      sets up a network namespace and runs all commands in that namespace
+  - valgrindPlugin.py
+      runs each command in the execute stage under valgrind,
+      and checks for leaks.
+      This plugin will output an extra test for each test in the test file,
+      one is the existing output as to whether the test passed or failed,
+      and the other is a test whether the command leaked memory or not.
+      (This one is a preliminary version, it may not work quite right yet,

+tdc - Adding plugins for tdc
+
+Author: Brenda J. Butler - [email protected]
+
+ADDING PLUGINS
+--------------
+
+A new plugin should be written in python as a class that inherits from TdcPlugin.
+There are some examples in plugin-lib.
+
+The plugin can be used to add functionality to the test framework,
+such as:
+
+- adding commands to be run before and/or after the test suite
+- adding commands to be run before and/or after the test cases
+- adding commands to be run before and/or after the execute phase of the test cases
+- ability to alter the command to be run in any phase:
+    pre        (the pre-suite stage)
+    prepare
+    execute
+    verify
+    teardown
+    post       (the post-suite stage)
+- ability to add to the command line args, and use them at run time
+
+
+The functions in the class should follow the following interfaces:
+
+    def __init__(self)
+    def pre_suite(self, testcount, testidlist)     # see "PRE_SUITE" below
+    def post_suite(self, ordinal)                  # see "SKIPPING" below
+    def pre_case(self, test_ordinal, testid)       # see "PRE_CASE" below
+    def post_case(self)
+    def pre_execute(self)
+    def post_execute(self)
+    def adjust_command(self, stage, command)       # see "ADJUST" below
+    def add_args(self, parser)                     # see "ADD_ARGS" below
+    def check_args(self, args, remaining)          # see "CHECK_ARGS" below
+
+
+PRE_SUITE
+
+This method takes a testcount (number of tests to be run) and
+testidlist (array of test ids for tests that will be run).  This is
+useful for various things, including when an exception occurs and the
+rest of the tests must be skipped.  The info is stored in the object,
+and the post_suite method can refer to it when dumping the "skipped"
+TAP output.  The tdc.py script will do that for the test suite as
+defined in the test case, but if the plugin is being used to run extra
+tests on each test (eg, check for memory leaks on associated
+co-processes) then that other tap output can be generated in the
+post-suite method using this info passed in to the pre_suite method.
+
+
+SKIPPING
+
+The post_suite method will receive the ordinal number of the last
+test to be attempted.  It can use this info when outputting
+the TAP output for the extra test cases.
+
+
+PRE_CASE
+
+The pre_case method will receive the ordinal number of the test
+and the test id.  Useful for outputing the extra test results.
+
+
+ADJUST
+
+The adjust_command method receives a string representing
+the execution stage and a string which is the actual command to be
+executed.  The plugin can adjust the command, based on the stage of
+execution.
+
+The stages are represented by the following strings:
+
+    'pre'
+    'setup'
+    'command'
+    'verify'
+    'teardown'
+    'post'
+
+The adjust_command method must return the adjusted command so tdc
+can use it.
+
+
+ADD_ARGS
+
+The add_args method receives the argparser object and can add
+arguments to it.  Care should be taken that the new arguments do not
+conflict with any from tdc.py or from other plugins that will be used
+concurrently.
+
+The add_args method should return the argparser object.
+
+
+CHECK_ARGS
+
+The check_args method is so that the plugin can do validation on
+the args, if needed.  If there is a problem, and Exception should
+be raised, with a string that explains the problem.
+
+eg:  raise Exception('plugin xxx, arg -y is wrong, fix it')
