adjustments are in progress
[ Upstream commit 1416270f4a1ae83ea84156ceba19a66a8f88be1f ]
In the past we've warned when ADJ_OFFSET was in progress, usually
caused by ntpd or some other time adjusting daemon running in non
steady sate, which can cause the skew calculations to be
incorrect.
Thus, this patch checks to see if the clock was being adjusted
when we fail so that we don't cause false negatives.

[ Upstream commit 7c27a26e1ed5a7dd709aa19685d2c98f64e1cf0c ]
There are some powerpc selftests, as tm/tm-unavailable, that run for a long
period (>120 seconds), and if it is interrupted, as pressing CRTL-C
(SIGINT), the foreground process (harness) dies but the child process and
threads continue to execute (with PPID = 1 now) in background.
In this case, you'd think the whole test exited, but there are remaining
threads and processes being executed in background. Sometimes these
zombies processes are doing annoying things, as consuming the whole CPU or
dumping things to STDOUT.
This patch fixes this problem by attaching an empty signal handler to
SIGINT in the harness process. This handler will interrupt (EINTR) the
parent process waitpid() call, letting the code to follow through the
normal flow, which will kill all the processes in the child process group.
This patch also fixes a typo.

[ Upstream commit ec348020566009d3da9b99f07c05814d13969c78 ]
When I wrote the sigreturn test, I didn't realize that AMD's busted
IRET behavior was different from Intel's busted IRET behavior:
On AMD CPUs, the CPU leaks the high 32 bits of the kernel stack pointer
to certain userspace contexts. Gee, thanks. There's very little
the kernel can do about it. Modify the test so it passes.

[ Upstream commit 88893cf787d3062c631cc20b875068eb11756e03 ]
Some tests cause the kernel to print things to the kernel log
buffer (ie. printk), in particular oops and warnings etc. However when
running all the tests in succession it's not always obvious which

We can narrow it down by printing which test directory we're running
in to /dev/kmsg, if it's writable.

[ Upstream commit cd4a6f3ab4d80cb919d15897eb3cbc85c2009d4b ]
The subpage_prot syscall is only functional when the system is using
the Hash MMU. Since commit 5b2b80714796 ("powerpc/mm: Invalidate
subpage_prot() system call on radix platforms") it returns ENOENT when
the Radix MMU is active. Currently this just makes the test fail.
Additionally the syscall is not available if the kernel is built with
4K pages, or if CONFIG_PPC_SUBPAGE_PROT=n, in which case it returns
ENOSYS because the syscall is missing entirely.
So check explicitly for ENOENT and ENOSYS and skip if we see either of
those.

writing a single space to the firmware_class.path parameter. This

Instead, write a null byte.

[ Upstream commit fe06fe860250a4f01d0eaf70a2563b1997174a74 ]
The tm-resched-dscr test has started failing sometimes, depending on
what compiler it's built with, eg:
test: tm_resched_dscr
Check DSCR TM context switch: tm-resched-dscr: tm-resched-dscr.c:76: test_body: Assertion `rv' failed.
!! child died by signal 6
When it fails we see that the compiler doesn't initialise rv to 1 before
entering the inline asm block. Although that's counter intuitive, it
is allowed because we tell the compiler that the inline asm will write
to rv (using "=r"), meaning the original value is irrelevant.
Marking it as a read/write parameter would presumably work, but it seems
simpler to fix it by setting the initial value of rv in the inline asm.

commit a9e017d5619eb371460c8e516f4684def62bef3a upstream.
The STR and SLDT instructions are not valid when running on virtual-8086
mode and generate an invalid operand exception. These two instructions are
protected by the Intel User-Mode Instruction Prevention (UMIP) security
feature. In protected mode, if UMIP is enabled, these instructions generate
a general protection fault if called from CPL > 0. Linux traps the general
protection fault and emulates the instructions sgdt, sidt and smsw; but not
str and sldt.
These tests are added to verify that the emulation code does not emulate
these two instructions but the expected invalid operand exception is
seen.
Tests fallback to exit with INT3 in case emulation does happen.

commit 9390afebe1d3f5a0be18b1afdd0ce09d67cebf9e upstream.
Certain user space programs that run on virtual-8086 mode may utilize
instructions protected by the User-Mode Instruction Prevention (UMIP)
security feature present in new Intel processors: SGDT, SIDT and SMSW. In
such a case, a general protection fault is issued if UMIP is enabled. When
such a fault happens, the kernel traps it and emulates the results of
these instructions with dummy values. The purpose of this new
test is to verify whether the impacted instructions can be executed
without causing such #GP. If no #GP exceptions occur, we expect to exit
virtual-8086 mode from INT3.
The instructions protected by UMIP are executed in representative use
cases:
a) displacement-only memory addressing
b) register-indirect memory addressing
c) results stored directly in operands
Unfortunately, it is not possible to check the results against a set of
expected values because no emulation will occur in systems that do not
have the UMIP feature. Instead, results are printed for verification. A
simple verification is done to ensure that results of all tests are
identical.

[ Upstream commit 2adfa4210f8f35cdfb4e08318cc06b99752964c2 ]
The 'configinit.sh' script checks the format of optional argument for the
build directory, printing an error message if the format is not valid.
However, the error message uses the wrong variable, indicating an empty
string even though the user entered a non-empty (but erroneous) string.
This commit fixes the script to use the correct variable.

[ Upstream commit 65c79230576873b312c3599479c1e42355c9f349 ]
The file /sys/module/firmware_class/parameters/path can be used
to set a custom firmware path. The fw_filesystem.sh script creates
a temporary directory to add a test firmware file to be used during
testing, in order for this to work it uses the custom path syfs file
and it was supposed to reset back the file on execution exit. The
script failed to do this due to a typo, it was using OLD_PATH instead
of OLD_FWPATH, since its inception since v3.17.
Its not as easy to just keep the old setting, it turns out that
resetting an empty setting won't actually do what we want, we need
to check if it was empty and set an empty space.
Without this we end up having the temporary path always set after
we run these tests.

commit 352909b49ba0d74929b96af6dfbefc854ab6ebb5 upstream.
This tests that the vsyscall entries do what they're expected to do.
It also confirms that attempts to read the vsyscall page behave as
expected.
If changes are made to the vsyscall code or its memory map handling,
running this test in all three of vsyscall=none, vsyscall=emulate,
and vsyscall=native are helpful.
(Because it's easy, this also compares the vsyscall results to their
vDSO equivalents.)
Note to KAISER backporters: please test this under all three
vsyscall modes. Also, in the emulate and native modes, make sure
that test_vsyscall_64 agrees with the command line or config
option as to which mode you're in. It's quite easy to mess up
the kernel such that native mode accidentally emulates
or vice versa.
Greg, etc: please backport this to all your Meltdown-patched
kernels. It'll help make sure the patches didn't regress
vsyscalls.

Now that we've added a 'trigger_async_request' knob to test the
request_firmware_nowait() API, let's use it. Also add tests for the
empty ("") string, since there have been a couple errors in that

Since we now have real ways that the sysfs write might fail, let's add
the appropriate check on the 'echo' lines too.

commit 796a3bae2fba6810427efdb314a1c126c9490fb3 upstream.
test_execve does rather odd mount manipulations to safely create
temporary setuid and setgid executables that aren't visible to the
rest of the system. Those executables end up in the test's cwd, but
that cwd is MNT_DETACHed.
The core namespace code considers MNT_DETACHed trees to belong to no
mount namespace at all and, in general, MNT_DETACHed trees are only
barely function. This interacted with commit 380cf5ba6b0a ("fs:
Treat foreign mounts as nosuid") to cause all MNT_DETACHed trees to
act as though they're nosuid, breaking the test.
Fix it by just not detaching the tree. It's still in a private
mount namespace and is therefore still invisible to the rest of the
system (except via /proc, and the same nosuid logic will protect all
other programs on the system from believing in test_execve's setuid
bits).
While we're at it, fix some blatant whitespace problems.

commit 65973dd3fd31151823f4b8c289eebbb3fb7e6bc0 upstream.
i386 glibc is buggy and calls the sigaction syscall incorrectly.
This is asymptomatic for normal programs, but it blows up on
programs that do evil things with segmentation. The ldt_gdt
self-test is an example of such an evil program.
This doesn't appear to be a regression -- I think I just got lucky
with the uninitialized memory that glibc threw at the kernel when I
wrote the test.
This hackish fix manually issues sigaction(2) syscalls to undo the
damage. Without the fix, ldt_gdt_32 segfaults; with the fix, it
passes for me.

commit d8d378fa1a0c98ecb50ca52c9bf3bc14e25aa2d2 upstream.
The unit tests crash when hotplug races the previous probe. This race
requires that the loading of the nfit_test module be terminated with
SIGTERM, and the module to be unloaded while the ars scan is still
running.
In contrast to the normal nfit driver, the unit test calls
acpi_nfit_init() twice to simulate hotplug, whereas the nominal case
goes through the acpi_nfit_notify() event handler. The
acpi_nfit_notify() path is careful to flush the previous region
registration before servicing the hotplug event. The unit test was
missing this guarantee.

commit ed8b0de5a33d2a2557dce7f9429dca8cb5bc5879 upstream.
"rm -rf" is bricking some peoples' laptops because of variables being
used to store non-reinitializable firmware driver data that's required
to POST the hardware.
These are 100% bugs, and they need to be fixed, but in the mean time it
shouldn't be easy to *accidentally* brick machines.
We have to have delete working, and picking which variables do and don't
work for deletion is quite intractable, so instead make everything
immutable by default (except for a whitelist), and make tools that
aren't quite so broad-spectrum unset the immutable flag.

When support for _FIT was added, the code presumed that the data
returned by the _FIT method is identical to the NFIT table, which
starts with an acpi_table_header. However, the _FIT is defined
to return a data in the format of a series of NFIT type structure
entries and as a method, has an acpi_object header rather tahn
an acpi_table_header.
To address the differences, explicitly save the acpi_table_header
from the NFIT, since it is accessible through /sys, and change
the nfit pointer in the acpi_desc structure to point to the
table entries rather than the headers.
