+/* This file contains sub-register zero extension checks for insns defining
+ * sub-registers, meaning:
+ *   - All insns under BPF_ALU class. Their BPF_ALU32 variants or narrow width
+ *     forms (BPF_END) could define sub-registers.
+ *   - Narrow direct loads, BPF_B/H/W | BPF_LDX.
+ *   - BPF_LD is not exposed to JIT back-ends, so no need for testing.
+ *
+ * "get_prandom_u32" is used to initialize low 32-bit of some registers to
+ * prevent potential optimizations done by verifier or JIT back-ends which could
+ * optimize register back into constant when range info shows one register is a
+ * constant.

+# A test for switch behavior under MC overload. An issue in Spectrum chips
+# causes throughput of UC traffic to drop severely when a switch is under heavy
+# MC load. This issue can be overcome by putting the switch to MC-aware mode.
+# This test verifies that UC performance stays intact even as the switch is
+# under MC flood, and therefore that the MC-aware mode is enabled and correctly
+# configured.
+#
+# Because mlxsw throttles CPU port, the traffic can't actually reach userspace
+# at full speed. That makes it impossible to use iperf3 to simply measure the
+# throughput, because many packets (that reach $h3) don't get to the kernel at
+# all even in UDP mode (the situation is even worse in TCP mode, where one can't
+# hope to see more than a couple Mbps).
+#
+# So instead we send traffic with mausezahn and use RX ethtool counters at $h3.
+# Multicast traffic is untagged, unicast traffic is tagged with PCP 1. Therefore
+# each gets a different priority and we can use per-prio ethtool counters to
+# measure the throughput. In order to avoid prioritizing unicast traffic, prio
+# qdisc is installed on $swp3 and maps all priorities to the same band #7 (and
+# thus TC 0).
+#
+# Mausezahn can't actually saturate the links unless it's using large frames.
+# Thus we set MTU to 10K on all involved interfaces. Then both unicast and

+====================
+Livepatch Self Tests
+====================
+
+This is a small set of sanity tests for the kernel livepatching.
+
+The test suite loads and unloads several test kernel modules to verify
+livepatch behavior.  Debug information is logged to the kernel's message
+buffer and parsed for expected messages.  (Note: the tests will clear
+the message buffer between individual tests.)
+
+
+Config
+------
+
+Set these config options and their prerequisites:
+
+CONFIG_LIVEPATCH=y
+CONFIG_TEST_LIVEPATCH=m
+
+
+Running the tests
+-----------------
+
+Test kernel modules are built as part of lib/ (make modules) and need to
+be installed (make modules_install) as the test scripts will modprobe
+them.
+
+To run the livepatch selftests, from the top of the kernel source tree:
+
+  % make -C tools/testing/selftests TARGETS=livepatch run_tests
+
+
+Adding tests
+------------
+
+See the common functions.sh file for the existing collection of utility
+functions, most importantly set_dynamic_debug() and check_result().  The
+latter function greps the kernel's ring buffer for "livepatch:" and
+"test_klp" strings, so tests be sure to include one of those strings for
+result comparison.  Other utility functions include general module
+loading and livepatch loading helpers (waiting for patch transitions,
+sysfs entries, etc.)

+ * Sigfuz(tm): A PowerPC TM-aware signal fuzzer.
+ *
+ * This is a new selftest that raises SIGUSR1 signals and handles it in a set
+ * of different ways, trying to create different scenario for testing
+ * purpose.
+ *
+ * This test works raising a signal and calling sigreturn interleaved with
+ * TM operations, as starting, suspending and terminating a transaction. The
+ * test depends on random numbers, and, based on them, it sets different TM
+ * states.
+ *
+ * Other than that, the test fills out the user context struct that is passed
+ * to the sigreturn system call with random data, in order to make sure that
+ * the signal handler syscall can handle different and invalid states
+ * properly.
+ *
+ * This selftest has command line parameters to control what kind of tests the
+ * user wants to run, as for example, if a transaction should be started prior
+ * to signal being raised, or, after the signal being raised and before the
+ * sigreturn. If no parameter is given, the default is enabling all options.
+ *
+ * This test does not check if the user context is being read and set
+ * properly by the kernel. Its purpose, at this time, is basically
+ * guaranteeing that the kernel does not crash on invalid scenarios.

-This document describes one way to create the initrd directory hierarchy
-in order to allow an initrd to be built into your kernel.  The trick
-here is to steal the initrd file used on your Linux laptop, Ubuntu in
-this case.  There are probably much better ways of doing this.
+The rcutorture scripting tools automatically create the needed initrd
+directory using dracut.  Failing that, this tool will create an initrd
+containing a single statically linked binary named "init" that loops
+over a very long sleep() call.  In both cases, this creation is done
+by tools/testing/selftests/rcutorture/bin/mkinitrd.sh.
 
-That said, here are the commands:
+However, if you are attempting to run rcutorture on a system that does
+not have dracut installed, and if you don't like the notion of static
+linking, you might wish to press an existing initrd into service:

-#define RSEQ_SIG	0x53053053
+/*
+ * - ARM little endian
+ *
+ * RSEQ_SIG uses the udf A32 instruction with an uncommon immediate operand
+ * value 0x5de3. This traps if user-space reaches this instruction by mistake,
+ * and the uncommon operand ensures the kernel does not move the instruction
+ * pointer to attacker-controlled code on rseq abort.
+ *
+ * The instruction pattern in the A32 instruction set is:
+ *
+ * e7f5def3    udf    #24035    ; 0x5de3
+ *
+ * This translates to the following instruction pattern in the T16 instruction
+ * set:
+ *
+ * little endian:
+ * def3        udf    #243      ; 0xf3
+ * e7f5        b.n    <7f5>
+ *
+ * - ARMv6+ big endian (BE8):
+ *
+ * ARMv6+ -mbig-endian generates mixed endianness code vs data: little-endian
+ * code and big-endian data. The data value of the signature needs to have its
+ * byte order reversed to generate the trap instruction:
+ *
+ * Data: 0xf3def5e7
+ *
+ * Translates to this A32 instruction pattern:
+ *
+ * e7f5def3    udf    #24035    ; 0x5de3
+ *
+ * Translates to this T16 instruction pattern:
+ *
+ * def3        udf    #243      ; 0xf3
+ * e7f5        b.n    <7f5>
+ *
+ * - Prior to ARMv6 big endian (BE32):
+ *
+ * Prior to ARMv6, -mbig-endian generates big-endian code and data
+ * (which match), so the endianness of the data representation of the
+ * signature should not be reversed. However, the choice between BE32
+ * and BE8 is done by the linker, so we cannot know whether code and
+ * data endianness will be mixed before the linker is invoked. So rather
+ * than try to play tricks with the linker, the rseq signature is simply
+ * data (not a trap instruction) prior to ARMv6 on big endian. This is
+ * why the signature is expressed as data (.word) rather than as
+ * instruction (.inst) in assembler.
