Before rebooting the box, a "ssh sync" is called to the test machine to see
if it is alive or not. But if the test machine is in a partial state, that
ssh may never actually finish, and the ktest test hangs.
Add a 10 second timeout to the sync test, which will fail after 10 seconds
and then cause the test to reboot the test machine.

For the last time, I screwed up my ktest config file, and the build went
into the default "randconfig", blowing away the .config that I had set up.
The reason for the default randconfig was because when this was first
written, I wanted to do a bunch of randconfigs. But as time progressed,
ktest isn't about randconfig anymore, and because randconfig destroys the
config in the build directory, it's a dangerous default to have. Use
oldconfig as the default.

This Kselftest update for Linux 5.6-rc5 consists of a cleanup patch
to undo changes to global .gitignore that added selftests/lkdtm
objects and add them to a local selftests/lkdtm/.gitignore.
Summary of Linus's comments on local vs. global gitignore scope:
- Keep local gitignore patterns in local files.
- Put only global gitignore patterns in the top-level gitignore file.
Local scope keeps things much better separated. It also incidentally
means that if a directory gets renamed, the gitignore file continues
to work unless in the case of renaming the actual files themselves that
are named in the gitignore.

The existing tests attempt to check that JMP32 JSET ignores the upper
bits in the operand registers. However, the tests missed one such bug in
the x32 JIT that is only uncovered when a previous instruction pollutes
the upper 32 bits of the registers.
This patch adds a new test case that catches the bug by first executing
a 64-bit JSET to pollute the upper 32-bits of the temporary registers,
followed by a 32-bit JSET which should ignore the upper 32 bits.

While rendering annotate browser from perf report tui, we keep track
of total number of lines(asm + source) in annotation->nr_entries and
total number of asm lines in annotation->nr_asm_entries. But we don't
reset them before starting. Thus if user annotates same function
multiple times, we restart incrementing these fields with old values.
This causes a segfault when user tries to toggle source code after
annotating same function multiple times. Fix it.

We are allocating disasm_line object in annotation_line__new() instead
of disasm_line__new(). Similarly annotation_line__delete() is actually
freeing disasm_line object as well. This complexity is because of
privsize. But we don't need privsize anymore so get rid of privsize and

For all the perf-config options that can also be set from command line
option, the preference is given to command line version in case of any
conflict. But that's opposite in case of perf annotate. i.e. the more
preference is given to default option rather than command line option.
Fix it.

perf annotate --show-nr-samples does not really show number of samples.
The reason is we have two separate variables for the same purpose.
One is in symbol_conf.show_nr_samples and another is
annotation_options.show_nr_samples.
We save command line option in symbol_conf.show_nr_samples but uses
annotation_option.show_nr_samples while rendering tui/stdio2 browser.
Though, we copy symbol_conf.show_nr_samples to
annotation__default_options.show_nr_samples but that is not really
effective as we don't use annotation__default_options once we copy
default options to dynamic variable annotate.opts in cmd_annotate().
Instead of all these complication, keep only one variable and use it all
over. symbol_conf.show_nr_samples is used by perf report/top as well. So
let's kill annotation_options.show_nr_samples.
On a side note, I've kept annotation_options.show_nr_samples definition
because it's still used by perf-config code. Follow up patch to fix
perf-config for annotate will remove annotation_options.show_nr_samples.

perf annotate --show-total-period does not really show total period.
The reason is we have two separate variables for the same purpose.
One is in symbol_conf.show_total_period and another is
annotation_options.show_total_period.
We save command line option in symbol_conf.show_total_period but uses
annotation_option.show_total_period while rendering tui/stdio2 browser.
Though, we copy symbol_conf.show_total_period to
annotation__default_options.show_total_period but that is not really
effective as we don't use annotation__default_options once we copy
default options to dynamic variable annotate.opts in cmd_annotate().
Instead of all these complication, keep only one variable and use it all
over. symbol_conf.show_total_period is used by perf report/top as well.
So let's kill annotation_options.show_total_period.
On a side note, I've kept annotation_options.show_total_period
definition because it's still used by perf-config code. Follow up patch
to fix perf-config for annotate will remove
annotation_options.show_total_period.

The 'perf annotate' TUI browser provides a 'r' hot key to switch to a

Add a specific test for the crash reported by Phil Sutter and addressed
in the previous patch. The test cases that, in my intention, should
have covered these cases, that is, the ones from the 'concurrency'
section, don't run these sequences tightly enough and spectacularly
failed to catch this.
While at it, define a convenient way to add these kind of tests, by
adding a "reported issues" test section.
It's more convenient, for this particular test, to execute the set
setup in its own function. However, future test cases like this one
might need to call setup functions, and will typically need no tools
other than nft, so allow for this in check_tools().
The original form of the reproducer used here was provided by Phil.

The commits introducing 'mlock-random-test'[1], 'map_fiex_noreplace'[2],
and 'thuge-gen'[3] have not added those in the 'run_vmtests' script and
thus the 'run_tests' command of kselftests doesn't run those. This
commit adds those in the script.
'gup_benchmark' and 'transhuge-stress' are also not included in the

performance measurement rather than pass/fail tests.

Add append value operator "+=" support to bootconfig syntax.
With this operator, user can add new value to the key as
an entry of array instead of overwriting.
For example,
foo = bar
...
foo += baz
Then the key "foo" has "bar" and "baz" values as an array.

Currently, bootconfig adds a new value on the existing key to the tail of an
array. But this looks a bit confusing because an admin can easily rewrite
the original value in the same config file.
This rejects the following value re-definition.
key = value1
...
key = value2
You should rewrite value1 to value2 in this case.

A value node can not co-exist with subkey node under some key
node, e.g.

This is not be allowed because bootconfig API is not designed
to handle such case.

Add bootconfig magic word to the end of bootconfig on initrd
image for indicating explicitly the bootconfig is there.
Also tools/bootconfig treats wrong size or wrong checksum or
parse error as an error, because if there is a bootconfig magic
word, there must be a bootconfig.
The bootconfig magic word is "#BOOTCONFIG\n", 12 bytes word.
Thus the block image of the initrd file with bootconfig is
as follows.
[Initrd][bootconfig][size][csum][#BOOTCONFIG\n]

Currently if you build with O=... the rseq tests don't build:
$ make O=$PWD/output -C tools/testing/selftests/ TARGETS=rseq
make: Entering directory '/linux/tools/testing/selftests'
...
make[1]: Entering directory '/linux/tools/testing/selftests/rseq'
gcc -O2 -Wall -g -I./ -I../../../../usr/include/ -L./ -Wl,-rpath=./ -shared -fPIC rseq.c -lpthread -o /linux/output/rseq/librseq.so
gcc -O2 -Wall -g -I./ -I../../../../usr/include/ -L./ -Wl,-rpath=./ basic_test.c -lpthread -lrseq -o /linux/output/rseq/basic_test
/usr/bin/ld: cannot find -lrseq
collect2: error: ld returned 1 exit status
This is because the library search path points to the source
directory, not the output.
We can fix it by changing the library search path to $(OUTPUT).

Commit 852c8cbf34 ("selftests/kselftest/runner.sh: Add 45 second
timeout per test") added a 45 second timeout for tests, and also added
a way for tests to customise the timeout via a settings file.
For example the ftrace tests take multiple minutes to run, so they
were given longer in commit b43e78f65b ("tracing/selftests: Turn off
timeout setting").
This works when the tests are run from the source tree. However if the
tests are installed with "make -C tools/testing/selftests install",
the settings files are not copied into the install directory. When the
tests are then run from the install directory the longer timeouts are
not applied and the tests timeout incorrectly.
So add the settings files to TEST_FILES of the appropriate Makefiles
to cause the settings files to be installed using the existing install
logic.
