x86/bugs: Increase the x86 bugs vector size to two u32s

2023-08-08T17:56:37+00:00

Upstream commit: 0e52740ffd10c6c316837c6c128f460f1aaba1ea

There was never a doubt in my mind that they would not fit into a single
u32 eventually.

tools headers cpufeatures: Sync with the kernel sources

2023-08-08T17:56:37+00:00

commit 1a9bcadd0058a3e81c1beca48e5e08dee9446a01 upstream.

To pick the changes from:

  3b9c723ed7cfa4e1 ("KVM: SVM: Add support for SVM instruction address check change")
  b85a0425d8056f3b ("Enumerate AVX Vector Neural Network instructions")
  fb35d30fe5b06cc2 ("x86/cpufeatures: Assign dedicated feature word for CPUID_0x8000001F[EAX]")

This only causes these perf files to be rebuilt:

  CC       /tmp/build/perf/bench/mem-memcpy-x86-64-asm.o
  CC       /tmp/build/perf/bench/mem-memset-x86-64-asm.o

And addresses this perf build warning:

  Warning: Kernel ABI header at 'tools/arch/x86/include/asm/cpufeatures.h' differs from latest version at 'arch/x86/include/asm/cpufeatures.h'
  diff -u tools/arch/x86/include/asm/cpufeatures.h arch/x86/include/asm/cpufeatures.h

x86/cpufeatures: Assign dedicated feature word for CPUID_0x8000001F[EAX]

2023-08-08T17:56:36+00:00

commit fb35d30fe5b06cc24444f0405da8fbe0be5330d1 upstream.

Collect the scattered SME/SEV related feature flags into a dedicated
word.  There are now five recognized features in CPUID.0x8000001F.EAX,
with at least one more on the horizon (SEV-SNP).  Using a dedicated word
allows KVM to use its automagic CPUID adjustment logic when reporting
the set of supported features to userspace.

No functional change intended.

selftests: tc: set timeout to 15 minutes

2023-07-27T06:37:40+00:00

commit fda05798c22a354efde09a76bdfc276b2d591829 upstream.

When looking for something else in LKFT reports [1], I noticed that the
TC selftest ended with a timeout error:

  not ok 1 selftests: tc-testing: tdc.sh # TIMEOUT 45 seconds

The timeout had been introduced 3 years ago, see the Fixes commit below.

This timeout is only in place when executing the selftests via the
kselftests runner scripts. I guess this is not what most TC devs are
using and nobody noticed the issue before.

The new timeout is set to 15 minutes as suggested by Pedro [2]. It looks
like it is plenty more time than what it takes in "normal" conditions.

perf dwarf-aux: Fix off-by-one in die_get_varname()

2023-07-27T06:37:17+00:00

[ Upstream commit 3abfcfd847717d232e36963f31a361747c388fe7 ]

The die_get_varname() returns "(unknown_type)" string if it failed to
find a type for the variable.  But it had a space before the opening
parenthesis and it made the closing parenthesis cut off due to the
off-by-one in the string length (14).

selftests/ptp: Fix timestamp printf format for PTP_SYS_OFFSET

2023-06-21T13:44:12+00:00

[ Upstream commit 76a4c8b82938bc5020b67663db41f451684bf327 ]

Previously, timestamps were printed using "%lld.%u" which is incorrect
for nanosecond values lower than 100,000,000 as they're fractional
digits, therefore leading zeros are meaningful.

This patch changes the format strings to "%lld.%09u" in order to add
leading zeros to the nanosecond value.

selftests: fib_tests: mute cleanup error message

2023-05-30T11:44:10+00:00

commit d226b1df361988f885c298737d6019c863a25f26 upstream.

In the end of the test, there will be an error message induced by the
`ip netns del ns1` command in cleanup()

  Tests passed: 201
  Tests failed:   0
  Cannot remove namespace file "/run/netns/ns1": No such file or directory

This can even be reproduced with just `./fib_tests.sh -h` as we're
calling cleanup() on exit.

Redirect the error message to /dev/null to mute it.

V2: Update commit message and fixes tag.
V3: resubmit due to missing netdev ML in V2

selftests/memfd: Fix unknown type name build failure

2023-05-30T11:44:09+00:00

Partially backport v6.3 commit 11f75a01448f ("selftests/memfd: add tests
for MFD_NOEXEC_SEAL MFD_EXEC") to fix an unknown type name build error.
In some systems, the __u64 typedef is not present due to differences in
system headers, causing compilation errors like this one:

fuse_test.c:64:8: error: unknown type name '__u64'
   64 | static __u64 mfd_assert_get_seals(int fd)

This header includes the  __u64 typedef which increases the likelihood
of successful compilation on a wider variety of systems.
