[ Upstream commit bc4c0a48bdad7f225740b8e750fdc1da6d85e1eb ]
The get_next_frame() function in psock_tpacket.c was missing a return
statement in its default switch case, leading to a compiler warning.
This was caused by a `bug_on(1)` call, which is defined as an
`assert()`, being compiled out because NDEBUG is defined during the
build.
Instead of adding a `return NULL;` which would silently hide the error
and could lead to crashes later, this change restores the original
author's intent. By adding `#undef NDEBUG` before including <assert.h>,
we ensure the assertion is active and will cause the test to abort if
this unreachable code is ever executed.

[ Upstream commit c36748e8733ef9c5f4cd1d7c4327994e5b88b8df ]
The `__WORDSIZE` macro, defined in the non-standard `<bits/wordsize.h>`
header, is a GNU extension and not universally available with all
toolchains, such as Clang when used with musl libc.
This can lead to build failures in environments where this header is
missing.
The intention of the code is to determine the bit width of a C `long`.
Replace the non-portable `__WORDSIZE` with the standard and portable
`sizeof(long) * 8` expression to achieve the same result.
This change also removes the inclusion of the now-unused
`<bits/wordsize.h>` header.

[ Upstream commit ca22da2fbd693b54dc8e3b7b54ccc9f7e9ba3640 ]
William reports kernel soft-lockups on some OVS topologies when TC mirred
egress->ingress action is hit by local TCP traffic [1].
The same can also be reproduced with SCTP (thanks Xin for verifying), when
client and server reach themselves through mirred egress to ingress, and
one of the two peers sends a "heartbeat" packet (from within a timer).
Enqueueing to backlog proved to fix this soft lockup; however, as Cong
noticed [2], we should preserve - when possible - the current mirred
behavior that counts as "overlimits" any eventual packet drop subsequent to
the mirred forwarding action [3]. A compromise solution might use the
backlog only when tcf_mirred_act() has a nest level greater than one:
change tcf_mirred_forward() accordingly.
Also, add a kselftest that can reproduce the lockup and verifies TC mirred
ability to account for further packet drops after TC mirred egress->ingress
(when the nest level is 1).

[2] https://lore.kernel.org/netdev/Y0w%2FWWY60gqrtGLp@pop-os.localdomain/
[3] such behavior is not guaranteed: for example, if RPS or skb RX
timestamping is enabled on the mirred target device, the kernel
can defer receiving the skb and return NET_RX_SUCCESS inside
tcf_mirred_forward().

[ Upstream commit 235174b2bed88501fda689c113c55737f99332d8 ]
Commit 4094871db1d6 ("udp: only do GSO if # of segs > 1") avoided GSO
for small packets. But the kernel currently dismisses GSO requests only
after checking MTU/PMTU on gso_size. This means any packets, regardless
of their payload sizes, could be dropped when PMTU becomes smaller than
requested gso_size. We encountered this issue in production and it
caused a reliability problem that new QUIC connection cannot be
established before PMTU cache expired, while non GSO sockets still
worked fine at the same time.
Ideally, do not check any GSO related constraints when payload size is
smaller than requested gso_size, and return EMSGSIZE instead of EINVAL
on MTU/PMTU check failure to be more specific on the error cause.

[ Upstream commit f67a90a0c8f5b3d0acc18f10650d90fec44775f9 ]
Lately, an additional locking was added by commit c0a40097f0bc
("drivers: core: synchronize really_probe() and dev_uevent()"). The
locking protects dev_uevent() calling. This function is used to send
messages from the kernel to user space. Uevent messages notify user space
about changes in device states, such as when a device is added, removed,
or changed. These messages are used by udev (or other similar user-space
tools) to apply device-specific rules.
After reloading devlink instance, udev events should be processed. This
locking causes a short delay of udev events handling.
One example for useful udev rule is renaming ports. 'forwading.config'
can be configured to use names after udev rules are applied. Some tests run
devlink_reload() and immediately use the updated names. This worked before
the above mentioned commit was pushed, but now the delay of uevent messages
causes that devlink_reload() returns before udev events are handled and
tests fail.
Adjust devlink_reload() to not assume that udev events are already
processed when devlink reload is done, instead, wait for udev events to
ensure they are processed before returning from the function.

[ Upstream commit af2b7e5b741aaae9ffbba2c660def434e07aa241 ]
In selftests/net/msg_zerocopy.c, it has a while loop keeps calling sendmsg
on a socket with MSG_ZEROCOPY flag, and it will recv the notifications
until the socket is not writable. Typically, it will start the receiving
process after around 30+ sendmsgs. However, as the introduction of commit
dfa2f0483360 ("tcp: get rid of sysctl_tcp_adv_win_scale"), the sender is
always writable and does not get any chance to run recv notifications.
The selftest always exits with OUT_OF_MEMORY because the memory used by
opt_skb exceeds the net.core.optmem_max. Meanwhile, it could be set to a
different value to trigger OOM on older kernels too.
Thus, we introduce "cfg_notification_limit" to force sender to receive
notifications after some number of sendmsgs.

[ Upstream commit 855067defa36b1f9effad8c219d9a85b655cf500 ]
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.
Fix this by tightening up the mirror action match. Change it from
matchall to a flower classifier matching on ICMP packets specifically.

[ Upstream commit 329c9cd769c2e306957df031efff656c40922c76 ]
The test tool can check that the zerocopy number of completions value is
valid taking into consideration the number of datagram send calls. This can
catch the system into a state where the datagrams are still in the system
(for example in a qdisk, waiting for the network interface to return a
completion notification, etc).
This change adds a retry logic of computing the number of completions up to
a configurable (via CLI) timeout (default: 2 seconds).

"udpgro_bench.sh" invokes udpgso_bench_rx/udpgso_bench_tx programs
subsequently and while doing so, there is a chance that the rx one is not

./udpgso_bench_tx: connect: Connection refused

Cited commit added the table ID to the FIB info structure, but did not
prevent structures with different table IDs from being consolidated.
This can lead to routes being flushed from a VRF when an address is
deleted from a different VRF.
Fix by taking the table ID into account when looking for a matching FIB
info. This is already done for FIB info structures backed by a nexthop
object in fib_find_info_nh().

[ Upstream commit d5082d386eee7e8ec46fa8581932c81a4961dcef ]
When the kernel receives a route deletion request from user space it
tries to delete a route that matches the route attributes specified in
the request.
If only prefix information is specified in the request, the kernel
should delete the first matching FIB alias regardless of its associated
FIB info. However, an error is currently returned when the FIB info is
backed by a nexthop object:
# ip nexthop add id 1 via 192.0.2.2 dev dummy10
# ip route add 198.51.100.0/24 nhid 1
# ip route del 198.51.100.0/24
RTNETLINK answers: No such process
Fix by matching on such a FIB info when legacy nexthop attributes are
not specified in the request. An earlier check already covers the case
where a nexthop ID is specified in the request.
Add tests that cover these flows. Before the fix:
# ./fib_nexthops.sh -t ipv4_fcnal

Add a test which causes a WARNING on kernels which treat a
nexthop route like a normal route when comparing for deletion and a
device is specified. That is, a route is found but we hit a warning while
matching it. The warning is from fib_info_nh() in include/net/nexthop.h
because we run it on a fib_info with nexthop object. The call chain is:
inet_rtm_delroute -> fib_table_delete -> fib_nh_match (called with a
nexthop fib_info and also with fc_oif set thus calling fib_info_nh on
the fib_info and triggering the warning).
Repro steps:
$ ip nexthop add id 12 via 172.16.1.3 dev veth1
$ ip route add 172.16.101.1/32 nhid 12

[ Upstream commit b8e629b05f5d23f9649c901bef09fab8b0c2e4b9 ]
As mentioned in the blamed commit, flood_unicast_test() works by
checking the match count on a tc filter placed on the receiving
interface.
But the second host interface (host2_if) has no interest in receiving a
packet with MAC DA de:ad:be:ef:13:37, so its RX filter drops it even
before the ingress tc filter gets to be executed. So we will incorrectly
get the message "Packet was not flooded when should", when in fact, the
packet was flooded as expected but dropped due to an unrelated reason,
at some other layer on the receiving side.
Force h2 to accept this packet by temporarily placing it in promiscuous
mode. Alternatively we could either deliver to its MAC address or use
tcpdump_start, but this has the fewest complications.
This fixes the "flooding" test from bridge_vlan_aware.sh and
bridge_vlan_unaware.sh, which calls flood_test from the lib.

operational
commit 3122257c02afd9f199a8fc84ae981e1fc4958532 upstream.
In emulated environments, the bridge ports enslaved to br1 get a carrier
before changing br1's PVID. This means that by the time the PVID is
changed, br1 is already operational and configured with an IPv6
link-local address.
When the test is run with netdevs registered by mlxsw, changing the PVID
is vetoed, as changing the VID associated with an existing L3 interface
is forbidden. This restriction is similar to the 8021q driver's
restriction of changing the VID of an existing interface.
Fix this by taking br1 down and bringing it back up when it is fully
configured.
With this fix, the test reliably passes on top of both the SW and HW
data paths (emulated or not).

[ Upstream commit b50d3b46f84282d795ae3076111acb75ae1031f3 ]
The purpose of the last test case is to test VXLAN encapsulation and
decapsulation when the underlay lookup takes place in a non-default VRF.
This is achieved by enslaving the physical device of the tunnel to a
VRF.
The binding of the VXLAN UDP socket to the VRF happens when the VXLAN
device itself is opened, not when its physical device is opened. This
was also mentioned in the cited commit ("tests that moving the underlay
from a VRF to another works when down/up the VXLAN interface"), but the
test did something else.
Fix it by reopening the VXLAN device instead of its physical device.

The cleanup() function takes care of killing processes launched by the

sees any process to kill:

Fix this by running cleanup() in the context of the test subshell.
Now that each test cleans the environment after completion, there's no
need for calling cleanup() again when the next test starts. So let's
drop it from the setup() function. This is okay because cleanup() is
also called when pmtu.sh starts, so even the first test starts in a
clean environment.
Also, use tcpdump's immediate mode. Otherwise it might not have time to
process buffered packets, resulting in missing packets or even empty
pcap files for short tests.
Note: PAUSE_ON_FAIL is still evaluated before cleanup(), so one can
still inspect the test environment upon failure when using -p.

[ Upstream commit 9c1952aeaa98b3cfc49e2a79cb2c7d6a674213e9 ]
udpgso_bench_tx call setup_sockaddr() for dest address before
parsing all arguments, if we specify "-p ${dst_port}" after "-D ${dst_ip}",
then ${dst_port} will be ignored, and using default cfg_port 8000.
This will cause test case "multiple GRO socks" failed in udpgro.sh.

[ Upstream commit 5471d5226c3b39b3d2f7011c082d5715795bd65c ]
The below referenced commit correctly updated the computation of number
of segments (gso_size) by using only the gso payload size and
removing the header lengths.
With this change the regression test started failing. Update
the tests to match this new behavior.
Both IPv4 and IPv6 tests are updated, as a separate patch in this series
will update udp_v6_send_skb to match this change in udp_send_skb.

[ Upstream commit 71da1aec215290e249d09c44c768df859f3a3bba ]
The recent GRE selftests defined NUM_NETIFS=10. If the users copy
forwarding.config.sample to forwarding.config directly, they will get
error "Command line is not complete" when run the GRE tests, because
create_netif_veth() failed with no interface name defined.
Fix it by extending the NETIFS with p9 and p10.

IPv6 allows binding a socket to a device then binding to an address
not on the device (__inet6_bind -> ipv6_chk_addr with strict flag
not set). Update the bind tests to reflect legacy behavior.
