selftests/ftrace: Add new test case which checks non unique symbol

2023-11-08T10:23:34+00:00

[ Upstream commit 03b80ff8023adae6780e491f66e932df8165e3a0 ]

If name_show() is non unique, this test will try to install a kprobe on this
function which should fail returning EADDRNOTAVAIL.
On kernel where name_show() is not unique, this test is skipped.

bpf: Clarify error expectations from bpf_clone_redirect

2023-10-10T19:46:40+00:00

[ Upstream commit 7cb779a6867fea00b4209bcf6de2f178a743247d ]

Commit 151e887d8ff9 ("veth: Fixing transmit return status for dropped
packets") exposed the fact that bpf_clone_redirect is capable of
returning raw NET_XMIT_XXX return codes.

This is in the conflict with its UAPI doc which says the following:
"0 on success, or a negative error in case of failure."

Update the UAPI to reflect the fact that bpf_clone_redirect can
return positive error numbers, but don't explicitly define
their meaning.

selftests/ftrace: Correctly enable event in instance-event.tc

2023-10-10T19:46:40+00:00

[ Upstream commit f4e4ada586995b17f828c6d147d1800eb1471450 ]

Function instance_set() expects to enable event 'sched_switch', so we
should set 1 to its 'enable' file.

Testcase passed after this patch:
  # ./ftracetest test.d/instances/instance-event.tc
  === Ftrace unit tests ===
  [1] Test creation and deletion of trace instances while setting an event
  [PASS]

selftests: tls: swap the TX and RX sockets in some tests

2023-10-10T19:46:37+00:00

[ Upstream commit c326ca98446e0ae4fee43a40acf79412b74cfedb ]

tls.sendmsg_large and tls.sendmsg_multiple are trying to send through
the self->cfd socket (only configured with TLS_RX) and to receive through
the self->fd socket (only configured with TLS_TX), so they're not using
kTLS at all. Swap the sockets.

selftests/tls: Add {} to avoid static checker warning

[ Upstream commit f50688b47c5858d2ff315d020332bf4cb6710837 ]

This silences a static checker warning due to the unusual macro
construction of EXPECT_*() by adding explicit {}s around the enclosing
while loop.

selftests: tracing: Fix to unmount tracefs for recovering environment

2023-09-23T09:00:06+00:00

[ Upstream commit 7e021da80f48582171029714f8a487347f29dddb ]

Fix to unmount the tracefs if the ftracetest mounted it for recovering
system environment. If the tracefs is already mounted, this does nothing.

perf tools: Add an option to build without libbfd

2023-09-23T09:00:05+00:00

[ Upstream commit 0d1c50ac488ebdaeeaea8ed5069f8d435fd485ed ]

Some distributions, like debian, don't link perf with libbfd. Add a
build flag to make this configuration buildable and testable.

This was inspired by:

perf jevents: Make build dependency on test JSONs

[ Upstream commit 517db3b59537a59f6cc251b1926df93e93bb9c87 ]

Currently all JSONs and the mapfile for an arch are dependencies for
building pmu-events.c

The test JSONs are missing as a dependency, so add them.
