selftests/ftrace: Fix to test kprobe $comm arg only if available

2019-11-28T17:28:39+00:00

[ Upstream commit 2452c96e617a0ff6fb2692e55217a3fa57a7322c ]

Test $comm in kprobe-event argument syntax testcase
only if it is supported on the kernel because
$comm has been introduced 4.8 kernel.
So on older stable kernel, it should be skipped.

selftests: net: reuseport_dualstack: fix uninitalized parameter

2019-11-10T10:23:25+00:00

[ Upstream commit d64479a3e3f9924074ca7b50bd72fa5211dca9c1 ]

This test reports EINVAL for getsockopt(SOL_SOCKET, SO_DOMAIN)
occasionally due to the uninitialized length parameter.
Initialize it to fix this, and also use int for "test_family" to comply
with the API standard.

selftests: netfilter: missing error check when setting up veth interface

2019-06-22T06:17:22+00:00

[ Upstream commit 82ce6eb1dd13fd12e449b2ee2c2ec051e6f52c43 ]

A test for the basic NAT functionality uses ip command which needs veth
device. There is a condition where the kernel support for veth is not
compiled into the kernel and the test script breaks. This patch contains
code for reasonable error display and correct code exit.

selftests/timers: Add missing fflush(stdout) calls

2019-06-22T06:17:20+00:00

[ Upstream commit fe48319243a626c860fd666ca032daacc2ba84a5 ]

When running under a pipe, some timer tests would not report output in
real-time because stdout flushes were missing after printf()s that lacked
a newline. This adds them to restore real-time status output that humans
can enjoy.

selftests/net: correct the return value for run_netsocktests

2019-05-16T17:43:43+00:00

[ Upstream commit 30c04d796b693e22405c38e9b78e9a364e4c77e6 ]

The run_netsocktests will be marked as passed regardless the actual test
result from the ./socket:

    selftests: net: run_netsocktests
    ========================================
    --------------------
    running socket test
    --------------------
    [FAIL]
    ok 1..6 selftests: net: run_netsocktests [PASS]

This is because the test script itself has been successfully executed.
Fix this by exit 1 when the test failed.

selftests: netfilter: check icmp pkttoobig errors are set as related

2019-05-16T17:43:42+00:00

[ Upstream commit becf2319f320cae43e20cf179cc51a355a0deb5f ]

When an icmp error such as pkttoobig is received, conntrack checks
if the "inner" header (header of packet that did not fit link mtu)
is matches an existing connection, and, if so, sets that packet as
being related to the conntrack entry it found.

It was recently reported that this "related" setting also works
if the inner header is from another, different connection (i.e.,
artificial/forged icmp error).

Add a test, followup patch will add additional "inner dst matches
outer dst in reverse direction" check before setting related state.

x86/selftests/pkeys: Fork() to check for state being preserved

2019-01-31T07:12:36+00:00

commit e1812933b17be7814f51b6c310c5d1ced7a9a5f5 upstream.

There was a bug where the per-mm pkey state was not being preserved across
fork() in the child.  fork() is performed in the pkey selftests, but all of
the pkey activity is performed in the parent.  The child does not perform
any actions sensitive to pkey state.

To make the test more sensitive to these kinds of bugs, add a fork() where
the parent exits, and execution continues in the child.

To achieve this let the key exhaustion test not terminate at the first
allocation failure and fork after 2*NR_PKEYS loops and continue in the
child.
