selftests: mptcp: userspace pm: skip if MPTCP is not supported

2023-06-09T08:48:21+00:00

commit 63212608a92a1ff10ae56dbb14e9fb685f7e4ffa upstream.

Selftests are supposed to run on any kernels, including the old ones not
supporting MPTCP.

A new check is then added to make sure MPTCP is supported. If not, the
test stops and is marked as "skipped".

selftests: mptcp: join: avoid using 'cmp --bytes'

2023-06-09T08:48:21+00:00

commit d328fe87067480cf2bd0b58dab428a98d31dbb7e upstream.

BusyBox's 'cmp' command doesn't support the '--bytes' parameter.

Some CIs -- i.e. LKFT -- use BusyBox and have the mptcp_join.sh test
failing [1] because their 'cmp' command doesn't support this '--bytes'
option:

    cmp: unrecognized option '--bytes=1024'
    BusyBox v1.35.0 () multi-call binary.

    Usage: cmp [-ls] [-n NUM] FILE1 [FILE2]

Instead, 'head --bytes' can be used as this option is supported by
BusyBox. A temporary file is needed for this operation.

Because it is apparently quite common to use BusyBox, it is certainly
better to backport this fix to impacted kernels.

selftests: mptcp: connect: skip if MPTCP is not supported

commit d83013bdf90a7994a474b0e650a7fc94b0d4ded6 upstream.

Selftests are supposed to run on any kernels, including the old ones not
supporting MPTCP.

A new check is then added to make sure MPTCP is supported. If not, the
test stops and is marked as "skipped". Note that this check can also
mark the test as failed if 'SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES' env
var is set to 1: by doing that, we can make sure a test is not being
skipped by mistake.

A new shared file is added here to be able to re-used the same check in
the different selftests we have.

selftests/ftrace: Choose target function for filter test from samples

2023-06-09T08:48:12+00:00

[ Upstream commit eb50d0f250e96ede9192d936d220cd97adc93b89 ]

Since the event-filter-function.tc expects the 'exit_mmap()' directly
calls 'kmem_cache_free()', this is vulnerable to code modifications.

Choose the target function for the filter test from the sample
event data so that it can keep test running correctly even if the caller
function name will be changed.

cpupower:Fix resource leaks in sysfs_get_enabled()

2023-06-09T08:48:02+00:00

[ Upstream commit e652be0f59d4ba4d5c636b1f7f4dcb73aae049fa ]

The sysfs_get_enabled() opened file processor not closed,
may cause a file handle leak.
Putting error handling and resource cleanup code together
makes the code easy to maintain and read.
Removed the unnecessary else if branch from the original
function, as it should return an error in cases other than '0'.
