It could not find __vdso_getcpu and __vdso_gettimeofday when test getcpu
and gettimeofday on LoongArch.
# make headers && cd tools/testing/selftests/vDSO && make
# ./vdso_test_getcpu
Could not find __vdso_getcpu
# ./vdso_test_gettimeofday
Could not find __vdso_gettimeofday
One simple way is to add LoongArch case to define version and name, just
like commit d942f231afc0 ("selftests/vDSO: Add riscv getcpu & gettimeofday
test"), but it is not the best way.
Since each architecture has already defined names and versions in
vdso_config.h, it is proper to include vdso_config.h to get version and
name for all archs.

Patch series "selftests/vDSO: Fix errors on LoongArch", v4.
This patch (of 2):
There exist the following errors when build vDSO selftests on LoongArch:
# make headers && cd tools/testing/selftests/vDSO && make
...
error: 'VDSO_VERSION' undeclared (first use in this function)
...
error: 'VDSO_NAMES' undeclared (first use in this function)
We can see the following code in arch/loongarch/vdso/vdso.lds.S:
VERSION
{
LINUX_5.10 {
global:
__vdso_getcpu;
__vdso_clock_getres;
__vdso_clock_gettime;
__vdso_gettimeofday;
__vdso_rt_sigreturn;
local: *;
};
}
so VDSO_VERSION should be 6 and VDSO_NAMES should be 1 for LoongArch,
add them to fix the building errors on LoongArch.

There are a couple of raw printf() calls in vdso_test_abi which result in
non KTAP conforment output such as
[vDSO kselftest] VDSO_VERSION: LINUX_2.6
Convert them to use ksft_print_msg() so that they don't cause confusion for

When logging the ID of the currently tested clock vdso_test_clock() puts a
spurious newline at the start of the format string resulting in output
such as
#
clock_id: CLOCK_BOOTTIME
which is a valid but empty KTAP informational message followed by a non
conferment output line. Remove the initial newline to create a more KTAP
friendly
# clock_id: CLOCK_BOOTTIME

The test results from vdso_abi_test are all formatted using a series of
macros:
#define VDSO_TEST_PASS_MSG() "\n%s(): PASS\n", __func__
#define VDSO_TEST_FAIL_MSG(x) "\n%s(): %s FAIL\n", __func__, x
#define VDSO_TEST_SKIP_MSG(x) "\n%s(): SKIP: Could not find %s\n", __func__, x
which don't play nicely with automated KTAP parsers since the actual KTAP
lines are in the form
ok 1
with no test name and we get an additional log line such as
vdso_test_gettimeofday(): PASS
with no preceeding # as KTAP requires. The lack of a test name means that
many automation systems will have a hard time distinguishing between the
different tests or correlating results between runs, the lack of # is less
severe but could potentially cause confusion.
Fix these issues by rewriting all the result reporting to include both the
vDSO function name being tested and (where there is one) the name of the
clock being tested in the main KTAP line. Since we have tests both with and
without a specific clock we abandon the helper macros and just put the
format strings used directly in the ksft_ API calls. When we fail to look
up the relevant vDSO symbol we add a separate print statement explaining
why the skip is being done. This gives output such as:
ok 1 __vdso_gettimeofday
# clock_id: CLOCK_REALTIME
# The time is 1700673118.58091596
ok 2 __vdso_clock_gettime CLOCK_REALTIME
which is much easier for test automation to work with.

is undefined
In the unlikely case that CLOCK_REALTIME is not defined, variable ret is
not initialized and further accumulation of return values to ret can leave
ret in an undefined state. Fix this by initialized ret to zero and changing
the assignment of ret to an accumulation for the CLOCK_REALTIME case.

The nds32 architecture, also known as AndeStar V3, is a custom 32-bit
RISC target designed by Andes Technologies. Support was added to the
kernel in 2016 as the replacement RISC-V based V5 processors were
already announced, and maintained by (current or former) Andes
employees.
As explained by Alan Kao, new customers are now all using RISC-V,
and all known nds32 users are already on longterm stable kernels
provided by Andes, with no development work going into mainline
support any more.
While the port is still in a reasonably good shape, it only gets
worse over time without active maintainers, so it seems best
to remove it before it becomes unusable. As always, if it turns
out that there are mainline users after all, and they volunteer
to maintain the port in the future, the removal can be reverted.

vdso_test_abi contains a batch of tests that verify the validity of the
vDSO ABI.
When a vDSO symbol is not found the relevant test is skipped reporting
KSFT_SKIP. All the tests return values are then added in a single
variable which is checked to verify failures. This approach can have
side effects which result in reporting the wrong kselftest exit status.
Fix vdso_test_abi verifying the return code of each test separately.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.
