+ * BPF_PROG2 is an enhanced version of BPF_PROG in order to handle struct

+ * of u64 values for each argument. Therefore, BPF_PROG2 has different
+ * syntax from BPF_PROG. For example, for the following BPF_PROG syntax:
+ *
+ * int BPF_PROG(test2, int a, int b) { ... }
+ *
+ * the corresponding BPF_PROG2 syntax is:
+ *
+ * int BPF_PROG2(test2, int, a, int, b) { ... }
+ *
+ * where type and the corresponding argument name are separated by comma.
+ *
+ * Use BPF_PROG2 macro if one of the arguments might be a struct/union larger
+ * than 8 bytes:
+ *
+ * int BPF_PROG2(test_struct_arg, struct bpf_testmod_struct_arg_1, a, int, b,
+ * int, c, int, d, struct bpf_testmod_struct_arg_2, e, int, ret)

+ * This test makes sure BPF stats collection using rstat works correctly.
+ * The test uses 3 BPF progs:
+ * (a) counter: This BPF prog is invoked every time we attach a process to a
+ * cgroup and locklessly increments a percpu counter.
+ * The program then calls cgroup_rstat_updated() to inform rstat
+ * of an update on the (cpu, cgroup) pair.
+ *
+ * (b) flusher: This BPF prog is invoked when an rstat flush is ongoing, it
+ * aggregates all percpu counters to a total counter, and also
+ * propagates the changes to the ancestor cgroups.
+ *
+ * (c) dumper: This BPF prog is a cgroup_iter. It is used to output the total
+ * counter of a cgroup through reading a file in userspace.
+ *
+ * The test sets up a cgroup hierarchy, and the above programs. It spawns a few
+ * processes in the leaf cgroups and makes sure all the counters are aggregated
+ * correctly.

-# This test sends 1Gbps of traffic through the switch, into which it then
-# injects a burst of traffic and tests that there are no drops.
-#
-# The 1Gbps stream is created by sending >1Gbps stream from H1. This stream
-# ingresses through $swp1, and is forwarded thtrough a small temporary pool to a
-# 1Gbps $swp3.
-#
-# Thus a 1Gbps stream enters $swp4, and is forwarded through a large pool to
-# $swp2, and eventually to H2. Since $swp2 is a 1Gbps port as well, no backlog
-# is generated.
-#
-# At this point, a burst of traffic is forwarded from H3. This enters $swp5, is
-# forwarded to $swp2, which is fully subscribed by the 1Gbps stream. The
-# expectation is that the burst is wholly absorbed by the large pool and no
-# drops are caused. After the burst, there should be a backlog that is hard to
-# get rid of, because $sw2 is fully subscribed. But because each individual
-# packet is scheduled soon after getting enqueued, SLL and HLL do not impact the
-# test.

+# This test sends many small packets (size is less than cell size) through the

+# are queued till they will be sent.
+#
+# The idea is to verify that the switch can handle at least 85% of maximum
+# supported descrpitors by hardware. Then, we verify that the driver configures
+# firmware to allow infinite size of egress descriptor pool, and does not use a
+# lower limitation. Increase the size of the relevant pools such that the pool's

+# This script is designed for testing the support of NEXT-C-SID flavor for SRv6
+# End behavior.
+# A basic knowledge of SRv6 architecture [1] and of the compressed SID approach
+# [2] is assumed for the reader.
+#
+# The network topology used in the selftest is depicted hereafter, composed by
+# two hosts and four routers. Hosts hs-1 and hs-2 are connected through an
+# IPv4/IPv6 L3 VPN service, offered by routers rt-1, rt-2, rt-3 and rt-4 using
+# the NEXT-C-SID flavor. The key components for such VPNs are:
+#
+# i) The SRv6 H.Encaps/H.Encaps.Red behaviors [1] apply SRv6 Policies on
+# traffic received by connected hosts, initiating the VPN tunnel;
+#
+# ii) The SRv6 End behavior [1] advances the active SID in the SID List
+# carried by the SRH;
+#
+# iii) The NEXT-C-SID mechanism [2] offers the possibility of encoding several
+# SRv6 segments within a single 128-bit SID address, referred to as a
+# Compressed SID (C-SID) container. In this way, the length of the SID
+# List can be drastically reduced.
+# The NEXT-C-SID is provided as a "flavor" of the SRv6 End behavior
+# which advances the current C-SID (i.e. the Locator-Node Function defined
+# in [2]) with the next one carried in the Argument, if available.
+# When no more C-SIDs are available in the Argument, the SRv6 End behavior
+# will apply the End function selecting the next SID in the SID List.
+#
+# iv) The SRv6 End.DT46 behavior [1] is used for removing the SRv6 Policy and,
+# thus, it terminates the VPN tunnel. Such a behavior is capable of
+# handling, at the same time, both tunneled IPv4 and IPv6 traffic.

+#
+# Local SID/C-SID table
+# =====================
+#
+# Each SRv6 router is configured with a Local SID/C-SID table in which
+# SIDs/C-SIDs are stored. Considering an SRv6 router rt-x, SIDs/C-SIDs are
+# configured in the Local SID/C-SIDs table as follows:
+#
+# Local SID/C-SID table for SRv6 router rt-x
+# +-----------------------------------------------------------+
+# |fcff:x::d46 is associated with the non-compressed SRv6 |
+# | End.DT46 behavior |
+# +-----------------------------------------------------------+
+# |fcbb:0:0x00::/48 is associated with the NEXT-C-SID flavor |
+# | of SRv6 End behavior |
+# +-----------------------------------------------------------+
+# |fcbb:0:0x00:d46::/64 is associated with the SRv6 End.DT46 |
+# | behavior when NEXT-C-SID compression is turned on |
+# +-----------------------------------------------------------+
+#
+# The fcff::/16 prefix is reserved for implementing SRv6 services with regular
+# (non compressed) SIDs. Reachability of SIDs is ensured by proper configuration
+# of the IPv6 routing tables in the routers.
+# Similarly, the fcbb:0::/32 prefix is reserved for implementing SRv6 VPN
+# services leveraging the NEXT-C-SID compression mechanism. Indeed, the
+# fcbb:0::/32 is used for encoding the Locator-Block while the Locator-Node
+# Function is encoded with 16 bits.
+#
+# Incoming traffic classification and application of SRv6 Policies
+# ================================================================
+#
+# An SRv6 ingress router applies different SRv6 Policies to the traffic received
+# from a connected host, considering the IPv4 or IPv6 destination address.
+# SRv6 policy enforcement consists of encapsulating the received traffic into a
+# new IPv6 packet with a given SID List contained in the SRH.
+# When the SID List contains only one SID, the SRH could be omitted completely
+# and that SID is stored directly in the IPv6 Destination Address (DA) (this is
+# called "reduced" encapsulation).
+#
+# Test cases for NEXT-C-SID
+# =========================
+#
+# We consider two test cases for NEXT-C-SID: i) single SID and ii) double SID.
+#
+# In the single SID test case we have a number of segments that are all
+# contained in a single Compressed SID (C-SID) container. Therefore the
+# resulting SID List has only one SID. Using the reduced encapsulation format
+# this will result in a packet with no SRH.
+#
+# In the double SID test case we have one segment carried in a Compressed SID
+# (C-SID) container, followed by a regular (non compressed) SID. The resulting
+# SID List has two segments and it is possible to test the advance to the next
+# SID when all the C-SIDs in a C-SID container have been processed. Using the
+# reduced encapsulation format this will result in a packet with an SRH
+# containing 1 segment.
+#
+# For the single SID test case, we use the IPv4 addresses of hs-1 and hs-2, for
+# the double SID test case, we use their IPv6 addresses. This is only done to
+# simplify the test setup and avoid adding other hosts or multiple addresses on
+# the same interface of a host.
+#
+# Traffic from hs-1 to hs-2
+# -------------------------
+#
+# Packets generated from hs-1 and directed towards hs-2 are handled by rt-1
+# which applies the SRv6 Policies as follows:
+#
+# i) IPv6 DA=cafe::2, H.Encaps.Red with SID List=fcbb:0:0400:0300:0200:d46::
+# ii) IPv4 DA=10.0.0.2, H.Encaps.Red with SID List=fcbb:0:0300::,fcff:2::d46
+#
+# ### i) single SID
+#
+# The router rt-1 is configured to enforce the given Policy through the SRv6
+# H.Encaps.Red behavior which avoids the presence of the SRH at all, since it
+# pushes the single SID directly in the IPv6 DA. Such a SID encodes a whole
+# C-SID container carrying several C-SIDs (e.g. 0400, 0300, etc).
+#
+# As the packet reaches the router rt-4, the enabled NEXT-C-SID SRv6 End
+# behavior (associated with fcbb:0:0400::/48) is triggered. This behavior
+# analyzes the IPv6 DA and checks whether the Argument of the C-SID container
+# is zero or not. In this case, the Argument is *NOT* zero and the IPv6 DA is
+# updated as follows:
+#
+# +---------------------------------------------------------------+
+# | Before applying the rt-4 enabled NEXT-C-SID SRv6 End behavior |
+# +---------------------------------------------------------------+
+# | +---------- Argument |
+# | vvvvvvvvvvvvvvvv |
+# | IPv6 DA fcbb:0:0400:0300:0200:d46:: |
+# | ^^^^ <-- shifting |
+# | | |
+# | Locator-Node Function |
+# +---------------------------------------------------------------+
+# | After applying the rt-4 enabled NEXT-C-SID SRv6 End behavior |
+# +---------------------------------------------------------------+
+# | +---------- Argument |
+# | vvvvvvvvvvvv |
+# | IPv6 DA fcbb:0:0300:0200:d46:: |
+# | ^^^^ |
+# | | |
+# | Locator-Node Function |
+# +---------------------------------------------------------------+
+#
+# After having applied the enabled NEXT-C-SID SRv6 End behavior, the packet is
+# sent to the next node, i.e. rt-3.
+#
+# The enabled NEXT-C-SID SRv6 End behavior on rt-3 is executed as the packet is
+# received. This behavior processes the packet and updates the IPv6 DA with
+# fcbb:0:0200:d46::, since the Argument is *NOT* zero. Then, the packet is sent
+# to the router rt-2.
+#
+# The router rt-2 is configured for decapsulating the inner IPv6 packet and,
+# for this reason, it applies the SRv6 End.DT46 behavior on the received
+# packet. It is worth noting that the SRv6 End.DT46 behavior does not require
+# the presence of the SRH: it is fully capable to operate properly on
+# IPv4/IPv6-in-IPv6 encapsulations.
+# At the end of the decap operation, the packet is sent to the
+# host hs-2.
+#
+# ### ii) double SID
+#
+# The router rt-1 is configured to enforce the given Policy through the SRv6
+# H.Encaps.Red. As a result, the first SID fcbb:0:0300:: is stored into the
+# IPv6 DA, while the SRH pushed into the packet is made of only one SID, i.e.
+# fcff:2::d46. Hence, the packet sent by hs-1 to hs-2 is encapsulated in an
+# outer IPv6 header plus the SRH.
+#
+# As the packet reaches the node rt-3, the router applies the enabled NEXT-C-SID
+# SRv6 End behavior.
+#
+# +---------------------------------------------------------------+
+# | Before applying the rt-3 enabled NEXT-C-SID SRv6 End behavior |
+# +---------------------------------------------------------------+
+# | +---------- Argument |
+# | vvvv (Argument is all filled with zeros) |
+# | IPv6 DA fcbb:0:0300:: |
+# | ^^^^ |
+# | | |
+# | Locator-Node Function |
+# +---------------------------------------------------------------+
+# | After applying the rt-3 enabled NEXT-C-SID SRv6 End behavior |
+# +---------------------------------------------------------------+
+# | |
+# | IPv6 DA fcff:2::d46 |
+# | ^^^^^^^^^^^ |
+# | | |
+# | SID copied from the SID List contained in the SRH |
+# +---------------------------------------------------------------+
+#
+# Since the Argument of the C-SID container is zero, the behavior can not
+# update the Locator-Node function with the next C-SID carried in the Argument
+# itself. Thus, the enabled NEXT-C-SID SRv6 End behavior operates as the
+# traditional End behavior: it updates the IPv6 DA by copying the next
+# available SID in the SID List carried by the SRH. After that, the packet is
+# sent to the node rt-2.
+#
+# Once the packet is received by rt-2, the router decapsulates the inner IPv6
+# packet using the SRv6 End.DT46 behavior (associated with the SID fcff:2::d46)
+# and sends it to the host hs-2.
+#
+# Traffic from hs-2 to hs-1
+# -------------------------
+#
+# Packets generated from hs-2 and directed towards hs-1 are handled by rt-2
+# which applies the SRv6 Policies as follows:
+#
+# i) IPv6 DA=cafe::1, SID List=fcbb:0:0300:0400:0100:d46::
+# ii) IPv4 DA=10.0.0.1, SID List=fcbb:0:0300::,fcff:1::d46
+#
+# For simplicity, such SRv6 Policies were chosen so that, in both use cases (i)
+# and (ii), the network paths crossed by traffic from hs-2 to hs-1 are the same
+# as those taken by traffic from hs-1 to hs-2.
+# In this way, traffic from hs-2 to hs-1 is processed similarly to traffic from
+# hs-1 to hs-2. So, the traffic processing scheme turns out to be the same as
+# that adopted in the use cases already examined (of course, it is necessary to
+# consider the different SIDs/C-SIDs).
