Commit 29f834aa32 ("net_sched: sch_fq: add 3 bands and WRR
scheduling") introduces multiple traffic bands, and per-band maximum
packet count.
Per-band limits ensures that packets in one class cannot fill the
entire qdisc and so cause DoS to the traffic in the other classes.
Verify this behavior:
1. set the limit to 10 per band
2. send 20 pkts on band A: verify that 10 are queued, 10 dropped
3. send 20 pkts on band A: verify that 0 are queued, 20 dropped
4. send 20 pkts on band B: verify that 10 are queued, 10 dropped
Packets must remain queued for a period to trigger this behavior.
Use SO_TXTIME to store packets for 100 msec.
The test reuses existing upstream test infra. The script is a fork of
cmsg_time.sh. The scripts call cmsg_sender.
The test extends cmsg_sender with two arguments:
* '-P' SO_PRIORITY
There is a subtle difference between IPv4 and IPv6 stack behavior:
PF_INET/IP_TOS sets IP header bits and sk_priority
PF_INET6/IPV6_TCLASS sets IP header bits BUT NOT sk_priority
* '-n' num pkts
Send multiple packets in quick succession.
I first attempted a for loop in the script, but this is too slow in
virtualized environments, causing flakiness as the 100ms timeout is
reached and packets are dequeued.
Also do not wait for timestamps to be queued unless timestamps are
requested.

Pull io_uring {get,set}sockopt support from Jens Axboe:
"This adds support for using getsockopt and setsockopt via io_uring.
The main use cases for this is to enable use of direct descriptors,
rather than first instantiating a normal file descriptor, doing the
option tweaking needed, then turning it into a direct descriptor. With
this support, we can avoid needing a regular file descriptor
completely.
The net and bpf bits have been signed off on their side"

Instead of defining basic io_uring functions in the test case, move them
to a common directory, so, other tests can use them.
This simplify the test code and reuse the common liburing
infrastructure. This is basically a copy of what we have in
io_uring_zerocopy_tx with some minor improvements to make checkpatch
happy.
A follow-up test will use the same helpers in a BPF sockopt test.

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.

Some highly optimised applications use SO_INCOMING_CPU to make them
efficient, but they didn't test if it's working correctly by getsockopt()
to avoid slowing down. As a result, no one noticed it had been broken
for years, so it's a good time to add a test to catch future regression.
The test does
1) Create $(nproc) TCP listeners associated with each CPU.
2) Create 32 child sockets for each listener by calling
sched_setaffinity() for each CPU.
3) Check if accept()ed sockets' sk_incoming_cpu matches
listener's one.
If we see -EAGAIN, SO_INCOMING_CPU is broken. However, we might not see
any error even if broken; the kernel could miraculously distribute all SYN
to correct listeners. Not to let that happen, we must increase the number
of clients and CPUs to some extent, so the test requires $(nproc) >= 2 and
creates 64 sockets at least.
Test:
$ nproc
96
$ ./so_incoming_cpu
Before the previous patch:
# Starting 12 tests from 5 test cases.
# RUN so_incoming_cpu.before_reuseport.test1 ...
# so_incoming_cpu.c:191:test1:Expected cpu (5) == i (0)

and then a listen() on the socket is invoked. The listen() should
succeed.
The sk_bind_sendto_listen test is copied over from one of syzbot's
tests: https://syzkaller.appspot.com/x/repro.c?x=1673a38df00000

This test populates the bhash table for a given port with
MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long
a bind request on the port takes.
When populating the bhash table, we create the sockets and then bind
the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT
are set). When timing how long a bind on the port takes, we bind on a
different address without SO_REUSEPORT set. We do not set SO_REUSEPORT
because we are interested in the case where the bind request does not
go through the tb->fastreuseport path, which is fragile (eg
tb->fastreuseport path does not work if binding with a different uid).
To run the script:
Usage: ./bind_bhash.sh [-6 | -4] [-p port] [-a address]
6: use ipv6
4: use ipv4
port: Port number
address: ip address
Without any arguments, ./bind_bhash.sh defaults to ipv6 using ip address
"2001:0db8:0:f101::1" on port 443.
On my local machine, I see:
ipv4:
before - 0.002317 seconds

for communicating with each other. Such routers make use of the SRv6
H.Encaps.Red behavior for applying SRv6 policies to L3 traffic coming
from hosts.
The correct execution of the behavior is verified through reachability
tests carried out between hosts belonging to the same VPN.

ipv4 arp_accept has a new option '2' to create new neighbor entries
only if the src ip is in the same subnet as an address configured on
the interface that received the garp message. This selftest tests all
options in arp_accept.
ipv6 has a sysctl endpoint, accept_untracked_na, that defines the
behavior for accepting untracked neighbor advertisements. A new option
similar to that of arp_accept for learning only from the same subnet is
added to accept_untracked_na. This selftest tests this new feature.

Stop using the KSFT_KHDR_INSTALL flag as installing the kernel headers
from the kselftest Makefile is causing some issues. Instead, rely on
the headers to be installed directly by the top-level Makefile
"headers_install" make target prior to building kselftest.

This test populates the bhash table for a given port with
MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long
a bind request on the port takes.
When populating the bhash table, we create the sockets and then bind
the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT
are set). When timing how long a bind on the port takes, we bind on a
different address without SO_REUSEPORT set. We do not set SO_REUSEPORT
because we are interested in the case where the bind request does not
go through the tb->fastreuseport path, which is fragile (eg
tb->fastreuseport path does not work if binding with a different uid).
To run the test locally, I did:
* ulimit -n 65535000
* ip addr add 2001:0db8:0:f101::1 dev eth0
* ./bind_bhash_test 443

This patch adds a test that has 300 VIPs listening on port 443.
Each VIP:443 will have 80 listening socks by using SO_REUSEPORT.
Thus, it will have 24000 listening socks.
Before removing the port only listening_hash, all socks will be in the
same port 443 bucket and inet_reuseport_add_sock() spends much time to
walk through the bucket. After removing the port only listening_hash
and move all usage to the port+addr lhash2, each bucket in the
ideal case has 80 sk which is much smaller than before.
Here is the test result from a qemu:
Before: listen 24000 socks took 210.210485362 (~210s)
After: listen 24000 socks took 0.207173 (~210ms)

When NET_F_F_GRO_FRAGLIST is enabled and bpf_skb_change_proto is used,
check if udp packets and tcp packets are successfully delivered to user
space. If wrong udp packets are delivered, udpgso_bench_rx will exit
with "Initial byte out of range"
