Add inval_create_ruleset_arguments, extension of
inval_create_ruleset_flags, to also check error ordering for
landlock_create_ruleset(2).
This is similar to the previous commit checking landlock_add_rule(2).
Test coverage for security/landlock is 94.4% of 504 lines accorging to
gcc/gcov-11.

According to the Landlock goal to be a security feature available to
unprivileges processes, it makes more sense to first check for
no_new_privs before checking anything else (i.e. syscall arguments).
Merge inval_fd_enforce and unpriv_enforce_without_no_new_privs tests
into the new restrict_self_checks_ordering. This is similar to the
previous commit checking other syscalls.

This makes more sense to first check the ruleset FD and then the rule

Use the standard interface order h1, swp1, swp2, h2 that is used by the
forwarding selftest framework. The previous order was confusing even
with the ASCII drawing. That isn't needed anymore.
This also drops the fixed MAC addresses and uses STABLE_MAC_ADDRS, which
ensures the MAC addresses are unique.

In commit f3054ffd71b5 ("selftests/powerpc: Return skip code for
spectre_v2"), the spectre_v2 selftest is updated to be aware of cases
where the vulnerability status reported in sysfs is incorrect, skipping
the test instead.
This happens because qemu can misrepresent the mitigation status of the
host to the guest. If the count cache is disabled in the host, and this
is correctly reported to the guest, then the guest won't apply
mitigations. If the guest is then migrated to a new host where
mitigations are necessary, it is now vulnerable because it has not
applied mitigations.
Update the selftest to report when we see excessive misses, indicative of
the count cache being disabled. If software flushing is enabled, also
warn that these flushes are just wasting performance.

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

It is currently limited to the is_mptcp field in case of plain TCP

errors like this:
libbpf: failed to open system Kconfig
libbpf: failed to load object 'kprobe_multi'
libbpf: failed to load BPF skeleton 'kprobe_multi': -22
It's because /proc/config.gz is opened in bpf_object__read_kconfig_file()

file = gzopen("/proc/config.gz", "r");
So this patch enables CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC in

Add a test to demonstrate that when the guest programs an event select
it is matched correctly in the pmu event filter and not inadvertently
filtered. This could happen on AMD if the high nybble[1] in the event
select gets truncated away only leaving the bottom byte[2] left for
matching.
This is a contrived example used for the convenience of demonstrating
this issue, however, this can be applied to event selects 0x28A (OC
Mode Switch) and 0x08A (L1 BTB Correction), where 0x08A could end up
being denied when the event select was only set up to deny 0x28A.

Currently, we simply hang using "while (1) ;" upon any unexpected

The above approach is not useful to anyone because KVM selftests
users will only see a hung application upon any unexpected guest
trap.
This patch improves unexpected guest trap handling for KVM RISC-V

1) Return to host user-space
2) Dump VCPU registers

When build bpf test and install it to another folder, e.g.
make -j10 install -C tools/testing/selftests/ TARGETS="bpf" \

The ima_setup.sh is missed in target folder, which makes test_ima failed.

hw_stats_l3.sh test is failing often for l3 stats shows less than 20
packets after 2 seconds sleep.
This is happening since there is a race between the 2 seconds sleep and
the netdevsim actually delivering the packets.
Increase the sleep time so the packets will be delivered successfully on
time.

Filter out -static for liburandom_read.so and its dependent target.

In case a distribution enables branch protection by default do as we do for
the main kernel and explicitly disable branch protection when building the
test case for having BTI disabled to ensure it doesn't get turned on by the
toolchain defaults.

The "bti" selftests are built with -nostdlib, which apparently
automatically creates a statically linked binary, which is what we want
and need for BTI (to avoid interactions with the dynamic linker).
However this is not true when building a PIE binary, which some
toolchains (Ubuntu) configure as the default.
When compiling btitest with such a toolchain, it will create a
dynamically linked binary, which will probably fail some tests, as the
dynamic linker might not support BTI:
===================
TAP version 13
1..18
not ok 1 nohint_func/call_using_br_x0
not ok 2 nohint_func/call_using_br_x16
not ok 3 nohint_func/call_using_blr
....
===================
To make sure we create static binaries, add an explicit -static on the
linker command line. This forces static linking even if the toolchain
defaults to PIE builds, and fixes btitest runs on BTI enabled machines.
