perf probe: Fix memory leak when synthesizing SDT probes

2020-12-30T10:51:29+00:00

[ Upstream commit 5149303fdfe5c67ddb51c911e23262f781cd75eb ]

The argv_split() function must be paired with argv_free(), else we must
keep a reference to the argv array received or do the freeing ourselves,
in synthesize_sdt_probe_command() we were simply leaking that argv[]
array.

perf record: Fix memory leak when using '--user-regs=?' to list registers

2020-12-30T10:51:28+00:00

[ Upstream commit 2eb5dd418034ecea2f7031e3d33f2991a878b148 ]

When using 'perf record's option '-I' or '--user-regs=' along with
argument '?' to list available register names, memory of variable 'os'
allocated by strdup() needs to be released before __parse_regs()
returns, otherwise memory leak will occur.

selftests/bpf: Fix broken riscv build

2020-12-30T10:51:09+00:00

[ Upstream commit 6016df8fe874e1cf36f6357d71438b384198ce06 ]

The selftests/bpf Makefile includes system include directories from
the host, when building BPF programs. On RISC-V glibc requires that
__riscv_xlen is defined. This is not the case for "clang -target bpf",
which messes up __WORDSIZE (errno.h -> ... -> wordsize.h) and breaks
the build.

By explicitly defining __risc_xlen correctly for riscv, we can
workaround this.

selftest/bpf: Add missed ip6ip6 test back

2020-12-30T10:51:06+00:00

[ Upstream commit 58cfa49c2ba7f815adccc27a775e7cf8a8f7f539 ]

In comment 173ca26e9b51 ("samples/bpf: add comprehensive ipip, ipip6,
ip6ip6 test") we added ip6ip6 test for bpf tunnel testing. But in commit
933a741e3b82 ("selftests/bpf: bpf tunnel test.") when we moved it to
the current folder, we didn't add it.

This patch add the ip6ip6 test back to bpf tunnel test. Update the ipip6's
topology for both IPv4 and IPv6 testing. Since iperf test is removed as
currect framework simplified it in purpose, I also removed unused tcp
checkings in test_tunnel_kern.c.

selftests: fix poll error in udpgro.sh

2020-12-30T10:50:56+00:00

[ Upstream commit 38bf8cd821be292e7d8e6f6283d67c5d9708f887 ]

The test program udpgso_bench_rx always invokes the poll()
syscall with a timeout of 10ms. If a larger timeout is specified
via the command line, udpgso_bench_rx is supposed to do multiple
poll() calls till the timeout is expired or an event is received.

Currently the poll() loop errors out after the first invocation with
no events, and may causes self-tests failure alike:

failed
 GRO with custom segment size            ./udpgso_bench_rx: poll: 0x0 expected 0x1

This change addresses the issue allowing the poll() loop to consume
all the configured timeout.

selftests/bpf/test_offload.py: Reset ethtool features after failed setting

2020-12-30T10:50:55+00:00

[ Upstream commit 766e62b7fcd2cf1d43e6594ba37c659dc48f7ddb ]

When setting the ethtool feature flag fails (as expected for the test), the
kernel now tracks that the feature was requested to be 'off' and refuses to
subsequently disable it again. So reset it back to 'on' so a subsequent
disable (that's not supposed to fail) can succeed.

ktest.pl: If size of log is too big to email, email error message

2020-12-21T12:27:05+00:00

commit 8cd6bc0359deebd8500e6de95899a8a78d3ec4ba upstream.

If the size of the error log is too big to send via email, and the sending
fails, it wont email any result. This can be confusing for the user who is
waiting for an email on the completion of the tests.

If it fails to send email, then try again without the log file stating that
it failed to send an email. Obviously this will not be of use if the sending
of email failed for some other reasons, but it will at least give the user
some information when it fails for the most common reason.
