For generality and conciseness, make an API which can be used in all
kvm libs and selftests to get vm guest mode strings. And the index i
is checked in the API in case of possiable faults.

Print the errno besides error-string in TEST_ASSERT in the format of
"errno=%d - %s" will explicitly indicate that the string is an error
information. Besides, the errno is easier to be used for debugging
than the error-string.

====================
Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next:
1) Add vlan match and pop actions to the flowtable offload,
patches from wenxu.
2) Reduce size of the netns_ct structure, which itself is
embedded in struct net Make netns_ct a read-mostly structure.
Patches from Florian Westphal.
3) Add FLOW_OFFLOAD_XMIT_UNSPEC to skip dst check from garbage
collector path, as required by the tc CT action. From Roi Dayan.
4) VLAN offload fixes for nftables: Allow for matching on both s-vlan
and c-vlan selectors. Fix match of VLAN id due to incorrect
byteorder. Add a new routine to properly populate flow dissector
ethertypes.
5) Missing keys in ip{6}_route_me_harder() results in incorrect
routes. This includes an update for selftest infra. Patches
from Ido Schimmel.
6) Add counter hardware offload support through FLOW_CLS_STATS.

Extend mptcp_connect tool with SO_MARK support (-M <value>) and
add a test case that checks that the packet mark gets copied to all
subflows.
This is done by only allowing packets with either skb->mark 1 or 2
via iptables.
DROP rule packet counter is checked; if its not zero, print an error
message and fail the test case.

Update various selftest error messages:
* The 'Rx tried to sub from different maps, paths, or prohibited types'
is reworked into more specific/differentiated error messages for better
guidance.
* The change into 'value -4294967168 makes map_value pointer be out of
bounds' is due to moving the mixed bounds check into the speculation
handling and thus occuring slightly later than above mentioned sanity
check.
* The change into 'math between map_value pointer and register with
unbounded min value' is similarly due to register sanity check coming
before the mixed bounds check.
* The case of 'map access: known scalar += value_ptr from different maps'
now loads fine given masks are the same from the different paths (despite
max map value size being different).

Add a kselftest for testing process-wide perf events with synchronous
SIGTRAP on events (using breakpoints). In particular, we want to test
that changes to the event propagate to all children, and the SIGTRAPs
are in fact synchronously sent to the thread where the event occurred.
Note: The "signal_stress" test case is also added later in the series to
perf tool's built-in tests. The test here is more elaborate in that
respect, which on one hand avoids bloating the perf tool unnecessarily,
but we also benefit from structured tests with TAP-compliant output that
the kselftest framework provides.

With clang compiler:
make -j60 LLVM=1 LLVM_IAS=1 <=== compile kernel
make -j60 -C tools/testing/selftests/bpf LLVM=1 LLVM_IAS=1
Some linker flags are not used/effective for some binaries and
we have warnings like:
warning: -lelf: 'linker' input unused [-Wunused-command-line-argument]
We also have warnings like:
.../selftests/bpf/prog_tests/ns_current_pid_tgid.c:74:57: note: treat the string as an argument to avoid this
if (CHECK(waitpid(cpid, &wstatus, 0) == -1, "waitpid", strerror(errno)))

fprintf(stdout, ##format); \
^
The first warning can be silenced with clang option -Wno-unused-command-line-argument.
For the second warning, source codes are modified as suggested by the compiler
to silence the warning. Since gcc does not support the option
-Wno-unused-command-line-argument and the warning only happens with clang
compiler, the option -Wno-unused-command-line-argument is enabled only when
clang compiler is used.

The suggested alternative for getting cache-inhibited memory with 'mem='
and /dev/mem is pretty hacky. Also, PAPR guests do not allow system
memory to be mapped cache-inhibited so despite /dev/mem being available
this will not work which can cause confusion. Instead recommend using
the memtrace buffers. memtrace is only available on powernv so there
will not be any chance of trying to do this in a guest.

Previously when mapping kernel memory on radix, no ptesync was
included which would periodically lead to unhandled spurious faults.
Mapping kernel memory is used when code patching with Strict RWX
enabled. As suggested by Chris Riedl, turning ftrace on and off does a
large amount of code patching so is a convenient way to see this kind
of fault.
Add a selftest to try and trigger this kind of a spurious fault. It
tests for 30 seconds which is usually long enough for the issue to
show up.

We need the driver core fixes in here as well.

The tracing test and the recent kfunc call test require
CONFIG_DYNAMIC_FTRACE. This patch adds it to the config file.

With a relatively recent clang master branch test_map skips a section,
libbpf: elf: skipping unrecognized data section(5) .rodata.str1.1
the cause is some pointless strings from bpf_printks in the BPF program
loaded during testing. After just removing the prints to fix above error
Daniel points out the program is a bit pointless and could be simply the
empty program returning SK_PASS.
Here we do just that and return simply SK_PASS. This program is used with
test_maps selftests to test insert/remove of a program into the sockmap
and sockhash maps. Its not testing actual functionality of the TCP
sockmap programs, these are tested from test_sockmap. So we shouldn't
lose in test coverage and fix above warnings. This original test was
added before test_sockmap existed and has been copied around ever since,
clean it up now.

Very occasionally, MPTCP selftests fail. Yeah, I saw that at least once!
Here we provide more details in case of errors with mptcp_join.sh script
like it was done with mptcp_connect.sh, see
commit 767389c8dd55 ("selftests: mptcp: dump more info on errors")

'mptcp_connect' already has a timeout for poll() but in some cases, it
is not enough.
With "timeout" tool, we will force the command to fail if it doesn't
finish on time. Thanks to that, the script will continue and display
details about the current state before marking the test as failed.
Displaying this state is very important to be able to understand the
issue. Best to have our CI reporting the issue than just "the test
hanged".
Note that in mptcp_connect.sh, we were using a long timeout to validate
the fact we cannot create a socket if a sysctl is set. We don't need
this timeout.
In diag.sh, we want to send signals to mptcp_connect instances that have
been started in the netns. But we cannot send this signal to 'timeout'
otherwise that will stop the timeout and messages telling us SIGUSR1 has
been received will be printed. Instead of trying to find the right PID
and storing them in an array, we can simply use the output of
'ip netns pids' which is all the PIDs we want to send signal to.
