in current Linux, MTU policing does not take into account that packets at
the TC ingress have the L2 header pulled. Thus, the same TC police action
(with the same value of tcfp_mtu) behaves differently for ingress/egress.
In addition, the full GSO size is compared to tcfp_mtu: as a consequence,
the policer drops GSO packets even when individual segments have the L2 +
L3 + L4 + payload length below the configured valued of tcfp_mtu.
Improve the accuracy of MTU policing as follows:
- account for mac_len for non-GSO packets at TC ingress.
- compare MTU threshold with the segmented size for GSO packets.
Also, add a kselftest that verifies the correct behavior.

The ->rtm_tos option is normally used to route packets based on both
the destination address and the DS field. However it's ignored for
IPv6 routes. Setting ->rtm_tos for IPv6 is thus invalid as the route
is going to work only on the destination address anyway, so it won't
behave as specified.

Use the new dscp_t type to replace the fc_tos field of fib_config, to
ensure IPv4 routes aren't influenced by ECN bits when configured with
non-zero rtm_tos.
Before this patch, IPv4 routes specifying an rtm_tos with some of the
ECN bits set were accepted. However they wouldn't work (never match) as
IPv4 normally clears the ECN bits with IPTOS_RT_MASK before doing a FIB
lookup (although a few buggy code paths don't).
After this patch, IPv4 routes specifying an rtm_tos with any ECN bit
set is rejected.
Note: IPv6 routes ignore rtm_tos altogether, any rtm_tos is accepted,

masking the ECN bits of ->flowi4_tos to prevent those from influencing

After this patch fib4-rules only compare the DSCP bits. ECN can't

Using tos 0x1 with 'ip route get <IPv4 address> ...' doesn't test much
of the tos option handling: 0x1 just sets an ECN bit, which is cleared
by inet_rtm_getroute() before doing the fib lookup. Let's use 0x10
instead, which is actually taken into account in the route lookup (and
is less surprising for the reader).
For consistency, use 0x10 for the IPv6 route lookup too (IPv6 currently
doesn't clear ECN bits, but might do so in the future).

Although both iproute2 and the kernel accept 1 and 2 as tos values for
new routes, those are invalid. These values only set ECN bits, which
are ignored during IPv4 fib lookups. Therefore, no packet can actually
match such routes. This selftest therefore only succeeds because it
doesn't verify that the new routes do actually work in practice (it
just checks if the routes are offloaded or not).
It makes more sense to use tos values that don't conflict with ECN.
This way, the selftest won't be affected if we later decide to warn or
even reject invalid tos configurations for new routes.

Core
----
- Defer freeing TCP skbs to the BH handler, whenever possible,
or at least perform the freeing outside of the socket lock section
to decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice
and net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.
- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF
---
- New helpers:
- bpf_find_vma(), find and inspect VMAs for profiling use cases
- bpf_loop(), runtime-bounded loop helper trading some execution
time for much faster (if at all converging) verification
- bpf_strncmp(), improve performance, avoid compiler flakiness
- bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
for tracing programs, all inlined by the verifier
- Support BPF relocations (CO-RE) in the kernel loader.
- Further the support for BTF_TYPE_TAG annotations.
- Allow access to local storage in sleepable helpers.
- Convert verifier argument types to a composable form with different
attributes which can be shared across types (ro, maybe-null).
- Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
creating new, extensible ones where missing and deprecating those
to be removed.
Protocols
---------
- WiFi (mac80211/cfg80211):
- notify user space about long "come back in N" AP responses,
allow it to react to such temporary rejections
- allow non-standard VHT MCS 10/11 rates
- use coarse time in airtime fairness code to save CPU cycles
- Bluetooth:
- rework of HCI command execution serialization to use a common
queue and work struct, and improve handling errors reported
in the middle of a batch of commands
- rework HCI event handling to use skb_pull_data, avoiding packet
parsing pitfalls
- support AOSP Bluetooth Quality Report
- SMC:
- support net namespaces, following the RDMA model
- improve connection establishment latency by pre-clearing buffers
- introduce TCP ULP for automatic redirection to SMC
- Multi-Path TCP:
- support ioctls: SIOCINQ, OUTQ, and OUTQNSD
- support socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT,
IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY
- support cmsgs: TCP_INQ
- improvements in the data scheduler (assigning data to subflows)
- support fastclose option (quick shutdown of the full MPTCP
connection, similar to TCP RST in regular TCP)
- MCTP (Management Component Transport) over serial, as defined by
DMTF spec DSP0253 - "MCTP Serial Transport Binding".
Driver API
----------
- Support timestamping on bond interfaces in active/passive mode.
- Introduce generic phylink link mode validation for drivers which
don't have any quirks and where MAC capability bits fully express
what's supported. Allow PCS layer to participate in the validation.
Convert a number of drivers.
- Add support to set/get size of buffers on the Rx rings and size of
the tx copybreak buffer via ethtool.
- Support offloading TC actions as first-class citizens rather than
only as attributes of filters, improve sharing and device resource
utilization.
- WiFi (mac80211/cfg80211):
- support forwarding offload (ndo_fill_forward_path)
- support for background radar detection hardware
- SA Query Procedures offload on the AP side
New hardware / drivers
----------------------
- tsnep - FPGA based TSN endpoint Ethernet MAC used in PLCs with
real-time requirements for isochronous communication with protocols

Pull networking updates from Jakub Kicinski:
"Core
----
- Defer freeing TCP skbs to the BH handler, whenever possible, or at
least perform the freeing outside of the socket lock section to
decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice and
net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.
- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF
---
- New helpers:
- bpf_find_vma(), find and inspect VMAs for profiling use cases
- bpf_loop(), runtime-bounded loop helper trading some execution
time for much faster (if at all converging) verification
- bpf_strncmp(), improve performance, avoid compiler flakiness
- bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
for tracing programs, all inlined by the verifier
- Support BPF relocations (CO-RE) in the kernel loader.
- Further the support for BTF_TYPE_TAG annotations.
- Allow access to local storage in sleepable helpers.
- Convert verifier argument types to a composable form with different
attributes which can be shared across types (ro, maybe-null).
- Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
creating new, extensible ones where missing and deprecating those
to be removed.
Protocols
---------
- WiFi (mac80211/cfg80211):
- notify user space about long "come back in N" AP responses,
allow it to react to such temporary rejections
- allow non-standard VHT MCS 10/11 rates
- use coarse time in airtime fairness code to save CPU cycles
- Bluetooth:
- rework of HCI command execution serialization to use a common
queue and work struct, and improve handling errors reported in
the middle of a batch of commands
- rework HCI event handling to use skb_pull_data, avoiding packet
parsing pitfalls
- support AOSP Bluetooth Quality Report
- SMC:
- support net namespaces, following the RDMA model
- improve connection establishment latency by pre-clearing buffers
- introduce TCP ULP for automatic redirection to SMC
- Multi-Path TCP:
- support ioctls: SIOCINQ, OUTQ, and OUTQNSD
- support socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT,
IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY
- support cmsgs: TCP_INQ
- improvements in the data scheduler (assigning data to subflows)
- support fastclose option (quick shutdown of the full MPTCP
connection, similar to TCP RST in regular TCP)
- MCTP (Management Component Transport) over serial, as defined by
DMTF spec DSP0253 - "MCTP Serial Transport Binding".
Driver API
----------
- Support timestamping on bond interfaces in active/passive mode.
- Introduce generic phylink link mode validation for drivers which
don't have any quirks and where MAC capability bits fully express
what's supported. Allow PCS layer to participate in the validation.
Convert a number of drivers.
- Add support to set/get size of buffers on the Rx rings and size of
the tx copybreak buffer via ethtool.
- Support offloading TC actions as first-class citizens rather than
only as attributes of filters, improve sharing and device resource
utilization.
- WiFi (mac80211/cfg80211):
- support forwarding offload (ndo_fill_forward_path)
- support for background radar detection hardware
- SA Query Procedures offload on the AP side
New hardware / drivers
----------------------
- tsnep - FPGA based TSN endpoint Ethernet MAC used in PLCs with
real-time requirements for isochronous communication with protocols
like OPC UA Pub/Sub.

MPTCP join self-tests are a bit fragile as they reply on
delays instead of events to catch-up with the expected
sockets states.
Replace the delay with state checking where possible and
reduce the number of sleeps in the most complex scenarios.
This will both reduce the tests run-time and will improve
stability.

Include into the path manager status a bitmap tracking the list
of local endpoints still available - not yet used - for the
relevant mptcp socket.
Keep such map updated at endpoint creation/deletion time, so
that we can easily skip already used endpoint at local address
selection time.
The endpoint used by the initial subflow is lazyly accounted at
subflow creation time: the usage bitmap is be up2date before
endpoint selection and we avoid such unneeded task in some relevant
scenarios - e.g. busy servers accepting incoming subflows but
not creating any additional ones nor annuncing additional addresses.
Overall this allows for fair local endpoints usage in case of
subflow failure.
As a side effect, this patch also enforces that each endpoint
is used at most once for each mptcp connection.

In a similar fashion to the asymmetric test, add a test for symmetric

In asymmetric routing the ingress VTEP routes the packet into the
correct VxLAN tunnel, whereas the egress VTEP only bridges the packet to
the correct host. Therefore, packets in different directions use
different VNIs - the target VNI.
Add a test which is similar to the existing IPv4 test to check IPv6.
The test uses a simple topology with two VTEPs and two VNIs and verifies
that ping passes between hosts (local / remote) in the same VLAN (VNI)
and in different VLANs belonging to the same tenant (VRF).
While the test does not check VM mobility, it does configure an anycast
gateway using a macvlan device on both VTEPs.

Add tests similar to vxlan_bridge_1d.sh and vxlan_bridge_1d_port_8472.sh.
The tests set up a topology with three VxLAN endpoints: one
"local", possibly offloaded, and two "remote", formed using veth pairs
and likely purely software bridges. The "local" endpoint is connected to
host systems by a VLAN-unaware bridge.
Since VxLAN tunnels must be unique per namespace, each of the "remote"

Currently `ping_do()` and `ping6_do()` send 10 packets.
There are cases that it is not possible to catch only the interesting
packets using tc rule, so then, it is possible to send many packets and
verify that at least this amount of packets hit the rule.
Add `PING_COUNT` variable, which is set to 10 by default, to allow tests

Currently rp_filter tests in fib_tests.sh:fib_rp_filter_test() are
failing. ping sockets are bound to dummy1 using the "-I" option
(SO_BINDTODEVICE), but socket lookup is failing when receiving ping
replies, since the routing table thinks they belong to dummy0.
For example, suppose ping is using a SOCK_RAW socket for ICMP messages.
When receiving ping replies, in __raw_v4_lookup(), sk->sk_bound_dev_if
is 3 (dummy1), but dif (skb_rtable(skb)->rt_iif) says 2 (dummy0), so the
raw_sk_bound_dev_eq() check fails. Similar things happen in
ping_lookup() for SOCK_DGRAM sockets.
These tests used to pass due to a bug [1] in iputils, where "ping -I"
actually did not bind ICMP message sockets to device. The bug has been
fixed by iputils commit f455fee41c07 ("ping: also bind the ICMP socket
to the specific device") in 2016, which is why our rp_filter tests
started to fail. See [2] .
Fixing the tests while keeping everything in one netns turns out to be
nontrivial. Rework the tests and build the following topology:
┌─────────────────────────────┐ ┌─────────────────────────────┐
│ network namespace 1 (ns1) │ │ network namespace 2 (ns2) │
│ │ │ │
│ ┌────┐ ┌─────┐ │ │ ┌─────┐ ┌────┐ │
│ │ lo │<───>│veth1│<────────┼────┼─>│veth2│<──────────>│ lo │ │
│ └────┘ ├─────┴──────┐ │ │ ├─────┴──────┐ └────┘ │
│ │192.0.2.1/24│ │ │ │192.0.2.1/24│ │
│ └────────────┘ │ │ └────────────┘ │
└─────────────────────────────┘ └─────────────────────────────┘
Consider sending an ICMP_ECHO packet A in ns2. Both source and
destination IP addresses are 192.0.2.1, and we use strict mode rp_filter
in both ns1 and ns2:
1. A is routed to lo since its destination IP address is one of ns2's
local addresses (veth2);
2. A is redirected from lo's egress to veth2's egress using mirred;
3. A arrives at veth1's ingress in ns1;
4. A is redirected from veth1's ingress to lo's ingress, again, using
mirred;
5. In __fib_validate_source(), fib_info_nh_uses_dev() returns false,
since A was received on lo, but reverse path lookup says veth1;
6. However A is not dropped since we have relaxed this check for lo in
commit 66f8209547 ("fib: relax source validation check for loopback
packets");
Making sure A is not dropped here in this corner case is the whole point
of having this test.
7. As A reaches the ICMP layer, an ICMP_ECHOREPLY packet, B, is
generated;
8. Similarly, B is redirected from lo's egress to veth1's egress (in
ns1), then redirected once again from veth2's ingress to lo's
ingress (in ns2), using mirred.
Also test "ping 127.0.0.1" from ns2. It does not trigger the relaxed
check in __fib_validate_source(), but just to make sure the topology
works with loopback addresses.

In commit 6de6e46d27 ("cls_flower: Fix inability to match GRE/IPIP
packets"), cls_flower was fixed to match an outer packet of a tunneled
packet as would be expected, rather than dissecting to the inner packet and
matching on that.
This fix uncovered several issues in packet matching in mirroring
selftests:
- in mirror_gre_bridge_1d_vlan.sh and mirror_gre_vlan_bridge_1q.sh, the
vlan_ethtype match is copied around as "ip", even as some of the tests
are running over ip6gretap. This is fixed by using an "ipv6" for
vlan_ethtype in the ip6gretap tests.
- in mirror_gre_changes.sh, a filter to count GRE packets is set up to
match TTL of 50. This used to trigger in the offloaded datapath, where
the envelope TTL was matched, but not in the software datapath, which
considered TTL of the inner packet. Now that both match consistently, all
the packets were double-counted. This is fixed by marking the filter as
skip_hw, leaving only the SW datapath component active.

In some platforms the numa node numbers are not necessarily consecutive,
meaning that not all nodes from 0 to the value returned by numa_max_node()
are available on the system. Using node numbers which are not available
results on errors from libnuma such as:
---- IPv4 UDP ----
send node 0, receive socket 0
libnuma: Warning: Cannot read node cpumask from sysfs
./reuseport_bpf_numa: failed to pin to node: No such file or directory
Fix it by checking if the node number bit is set on numa_nodes_ptr, which
is defined on libnuma as "Set with all nodes the kernel has exposed to
userspace".

Explicitly pass -6 to netcat when the test is using IPv6 to prevent
failures.
Also make sure to pass "-N" to netcat to close the socket after EOF on
the client side, otherwise we would always hit the timeout and the test
would fail.

Currently the simult_flows.sh self-tests are not very stable,
especially when running on slow VMs.
The tests measure runtime for transfers on multiple subflows
and check that the time is near the theoretical maximum.
The current test infra introduces a bit of jitter in test
runtime, due to multiple explicit delays. Additionally the
runtime is measured by the shell script wrapper. On a slow
VM, the script overhead is measurable and subject to relevant
jitter.
One solution to make the test more stable would be adding more
slack to the expected time; that could possibly hide real
regressions. Instead move the measurement inside the command
doing the transfer, and drop most unneeded sleeps.

When I fixed IGMPv3/MLDv2 to use the bridge's multicast_membership_interval
value which is chosen by user-space instead of calculating it based on
multicast_query_interval and multicast_query_response_interval I forgot
to update the selftests relying on that behaviour. Now we have to
manually set the expected GMI value to perform the tests correctly and get
proper results (similar to IGMPv2 behaviour).

A number of mlxsw-specific selftests currently detect whether they are run
on a compatible machine, and bail out silently when not. These tests are
however done in a somewhat impenetrable manner by directly comparing PCI
IDs against a blacklist or a whitelist, and bailing out silently if the
machine is not compatible.
Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying
the supported machines in a human-readable manner. If the current machine
is incompatible, the helper emits a SKIP message and returns an error code,
based on which the caller can gracefully bail out in a suitable way. This
allows a more readable conditions such as:
mlxsw_only_on_spectrum 2+ || return
Convert all existing open-coded guards to the new helper. Also add two new
guards to do_mark_test() and do_drop_test(), which are supported only on
Spectrum-2+, but the corresponding check was not there.

These programs are useful, but not all selftests require them.
Additionally, on embedded boards without package management (things like
buildroot), installing mausezahn or jq is not always as trivial as
downloading a package from the web.
So it is actually a bit annoying to require programs that are not used.
Introduce options that can be set by scripts to not enforce these
dependencies. For compatibility, default to "yes".

The current default does not allowing additional subflows, mostly
as a safety restriction to avoid uncontrolled resource consumption
on busy servers.
Still the system admin and/or the application have to opt-in to
MPTCP explicitly. After that, they need to change (increase) the
default maximum number of additional subflows.
Let set that to reasonable default, and make end-users life easier.
Additionally we need to update some self-tests accordingly.

Test that applications binding listening sockets to VRFs without
specifying TCP_MD5SIG_FLAG_IFINDEX will work as expected. This would
be broken if __tcp_md5_do_lookup always made a strict comparison on
l3index. See this email:
https://lore.kernel.org/netdev/209548b5-27d2-2059-f2e9-2148f5a0291b@gmail.com/
Applications using tcp_l3mdev_accept=1 and a single global socket (not
bound to any interface) also should have a way to specify keys that are
only for the default VRF, this is done by --force-bind-key-ifindex
without otherwise binding to a device.

Do this by converting to getopt_long because nettest has too many
