Add a test case for IPv6 source address delete.
As David suggested, add tests:
- Single device using src address
- Two devices with the same source address
- VRF with single device using src address
- VRF with two devices using src address
As Ido points out, in IPv6, the preferred source address is looked up in
the same VRF as the first nexthop device. This will give us similar results
to IPv4 if the route is installed in the same VRF as the nexthop device, but
not when the nexthop device is enslaved to a different VRF. So add tests:
- src address and nexthop dev in same VR
- src address and nexthop device in different VRF
The link local address delete logic is different from the global address.
It should only affect the associate device it bonds to. So add tests cases
for link local address testing.
Here is the test result:
IPv6 delete address route tests
Single device using src address
TEST: Prefsrc removed when src address removed on other device [ OK ]
Two devices with the same source address
TEST: Prefsrc not removed when src address exist on other device [ OK ]
TEST: Prefsrc removed when src address removed on all devices [ OK ]
VRF with single device using src address
TEST: Prefsrc removed when src address removed on other device [ OK ]
VRF with two devices using src address
TEST: Prefsrc not removed when src address exist on other device [ OK ]
TEST: Prefsrc removed when src address removed on all devices [ OK ]
src address and nexthop dev in same VRF
TEST: Prefsrc removed from VRF when source address deleted [ OK ]
TEST: Prefsrc in default VRF not removed [ OK ]
TEST: Prefsrc not removed from VRF when source address exist [ OK ]
TEST: Prefsrc in default VRF removed [ OK ]
src address and nexthop device in different VRF
TEST: Prefsrc not removed from VRF when nexthop dev in diff VRF [ OK ]
TEST: Prefsrc not removed in default VRF [ OK ]
TEST: Prefsrc removed from VRF when nexthop dev in diff VRF [ OK ]
TEST: Prefsrc removed in default VRF [ OK ]
Table ID 0
TEST: Prefsrc removed from default VRF when source address deleted [ OK ]
Link local source route
TEST: Prefsrc not removed when delete ll addr from other dev [ OK ]
TEST: Prefsrc removed when delete ll addr [ OK ]
TEST: Prefsrc not removed when delete ll addr from other dev [ OK ]
TEST: Prefsrc removed even ll addr still exist on other dev [ OK ]

As the initial commit 1a01727676 ("selftests: Add VRF route leaking
tests") said, the IPv6 MTU test fails as source address selection
picking ::1. Every time we run the selftest this one report failed.
There seems not much meaning to keep reporting a failure for 3 years
that no one plan to fix/update. Let't just skip this one first. We can
add it back when the issue fixed.

Currently any error during render leads to output an empty file.
That is quite annoying when using tools/net/ynl/ynl-regen.sh
which git greps files with content of "YNL-GEN.." and therefore ignores
empty files. So once you fail to regen, you have to checkout the file.
Avoid that by rendering to a temporary file first, only at the end
copy the content to the actual destination.

Implement a new test program mptcpify: if the family is AF_INET or
AF_INET6, the type is SOCK_STREAM, and the protocol ID is 0 or
IPPROTO_TCP, set it to IPPROTO_MPTCP. It will be hooked in
update_socket_protocol().
Extend the MPTCP test base, add a selftest test_mptcpify() for the
mptcpify case. Open and load the mptcpify test prog to mptcpify the
TCP sockets dynamically, then use start_server() and connect_to_fd()
to create a TCP socket, but actually what's created is an MPTCP
socket, which can be verified through 'getsockopt(SOL_PROTOCOL)'
and 'getsockopt(MPTCP_INFO)'.

This selftest is designed for testing the support of NEXT-C-SID flavor
for SRv6 End.X behavior. It instantiates a virtual network composed of
several nodes: hosts and SRv6 routers. Each node is realized using a
network namespace that is properly interconnected to others through veth
pairs, according to the topology depicted in the selftest script file.
The test considers SRv6 routers implementing IPv4/IPv6 L3 VPNs leveraged
by hosts for communicating with each other. Such routers i) apply
different SRv6 Policies to the traffic received from connected hosts,
considering the IPv4 or IPv6 protocols; ii) use the NEXT-C-SID
compression mechanism for encoding several SRv6 segments within a single
128-bit SID address, referred to as a Compressed SID (C-SID) container.
The NEXT-C-SID is provided as a "flavor" of the SRv6 End.X behavior,
enabling it to properly process the C-SID containers. The correct
execution of the enabled NEXT-C-SID SRv6 End.X behavior is verified
through reachability tests carried out between hosts belonging to the
same VPN.

This test verifies whether the encapsulated packets have the correct
configured TTL. It does so by sending ICMP packets through the test
topology and mirroring them to a gretap netdevice. On a busy host
however, more than just the test ICMP packets may end up flowing
through the topology, get mirrored, and counted. This leads to
potential spurious failures as the test observes much more mirrored
packets than the sent test packets, and assumes a bug.

Test if the correct drop reason is reported when OVS drops a packet due

From: Eric Garver <eric@garver.life>
This adds an explicit drop action. This is used by OVS to drop packets
for which it cannot determine what to do. An explicit action in the
kernel allows passing the reason _why_ the packet is being dropped or
zero to indicate no particular error happened (i.e: OVS intentionally
dropped the packet).
Since the error codes coming from userspace mean nothing for the kernel,
we squash all of them into only two drop reasons:
- OVS_DROP_EXPLICIT_WITH_ERROR to indicate a non-zero value was passed
- OVS_DROP_EXPLICIT to indicate a zero value was passed (no error)
e.g. trace all OVS dropped skbs
# perf trace -e skb:kfree_skb --filter="reason >= 0x30000"
[..]
106.023 ping/2465 skb:kfree_skb(skbaddr: 0xffffa0e8765f2000, \
location:0xffffffffc0d9b462, protocol: 2048, reason: 196611)
reason: 196611 --> 0x30003 (OVS_DROP_EXPLICIT)
Also, this patch allows ovs-dpctl.py to add explicit drop actions as:
"drop" -> implicit empty-action drop
"drop(0)" -> explicit non-error action drop
"drop(42)" -> explicit error action drop

Add a test case to check whether sockmap redirection works correctly
when data length returned by stream_parser is less than skb->len.
In addition, this test checks whether strp_done is called correctly.
The reason is that we returns skb->len - 1 from the stream_parser, so
the last byte in the skb will be held by strp->skb_head. Therefore,
if strp_done is not called to free strp->skb_head, we'll get a memleak
warning.

It’s because the recv(... MSG_DONTWAIT) syscall in the test case is
called before the queued work sk_psock_backlog() in the kernel finishes
executing. So the data to be read is still queued in psock->ingress_skb
and cannot be read by the user program. Therefore, the non-blocking
recv() reads nothing and reports an EAGAIN error.
So replace recv(... MSG_DONTWAIT) with xrecv_nonblock(), which calls
select() to wait for data to be readable or timeout before calls recv().

The reason behind commit af7b29b1de ("Revert "net/sched: taprio: make

patch it reverted caused a crash when attaching a CBS shaper to one of
the taprio classes. Prevent that from happening again by adding a test
case for it, which now passes correctly in both offload and software

Check that the "Can only be attached as root qdisc" error message from
taprio is effective by attempting to attach it to a class of another
taprio qdisc. That operation should fail.
In the bug that was squashed by change "net/sched: taprio: try again to
report q->qdiscs[] to qdisc_leaf()", grafting a child taprio to a root
software taprio would be misinterpreted as a change() to the root
taprio. Catch this by looking at whether the base-time of the root
taprio has changed to follow the base-time of the child taprio,
something which should have absolutely never happened assuming correct
semantics.
Vinicius points out that looking at "base_time" in the tc qdisc show
output is unreliable because user space is in a race with the kernel
applying the setting. So we create a helper bash script which waits
while there is any pending schedule.

This makes a difference for the software scheduling mode, where
dev_queue->qdisc_sleeping is the same as the taprio root Qdisc itself,
but when we're talking about what Qdisc and stats get reported for a
traffic class, the root taprio isn't what comes to mind, but q->qdiscs[]

To understand the difference, I've attempted to send 100 packets in
software mode through class 8001:5, and recorded the stats before and
after the change.
Here is before:

and here is after:
class taprio 8001:1 root

backlog 0b 0p requeues 0
window_drops 0
class taprio 8001:2 root

The most glaring (and expected) difference is that before, all class
stats reported the global stats, whereas now, they really report just
the counters for that traffic class.
Finally, Pedro Tammela points out that there is a tc selftest which
checks specifically which handle do the child Qdiscs corresponding to
each class have. That's changing here - taprio no longer reports
tcm->tcm_info as the same handle "1:" as itself (the root Qdisc), but 0
(the handle of the default pfifo child Qdiscs). Since iproute2 does not
print a child Qdisc handle of 0, adjust the test's expected output.

Some test cases check that the group timer is (or isn't) 0. Instead of
grepping for "0.00" grep for " 0.00" as the former can also match
"260.00" which is the default group membership interval.

As explained in commit 8bcfb4ae4d ("selftests: forwarding: Fix failing
tests with old libnet"), old versions of libnet (used by mausezahn) do
not use the "SO_BINDTODEVICE" socket option. For IP unicast packets,
this can be solved by prefixing mausezahn invocations with "ip vrf
exec". However, IP multicast packets do not perform routing and simply
egress the bound device, which does not exist in this case.
Fix by specifying the source and destination MAC of the packet which
will cause mausezahn to use a packet socket instead of an IP socket.

The test installs filters that match on various IP fragments (e.g., no
fragment, first fragment) and expects a certain amount of packets to hit
each filter. This is problematic as the filters are not specific enough
and can match IP packets (e.g., IGMP) generated by the stack, resulting
in failures [1].
Fix by making the filters more specific and match on more fields in the
IP header: Source IP, destination IP and protocol.

The test checks that filters that match on source or destination MAC
were only hit once. A host can send more than one packet with a given
source or destination MAC, resulting in failures.
Fix by relaxing the success criterion and instead check that the filters
were not hit zero times. Using tc_check_at_least_x_packets() is also an
option, but it is not available in older kernels.

The test relies on 'nc' being the netcat version from the nmap project.
While this seems to be the case on Fedora, it is not the case on Ubuntu,
resulting in failures such as [1].
Fix by explicitly using the 'ncat' utility from the nmap project and the
skip the test in case it is not installed.
