selftests/powerpc: Fix compile error on tlbie_test due to newer gcc

2019-11-10T10:25:42+00:00

commit 5b216ea1c40cf06eead15054c70e238c9bd4729e upstream.

Newer versions of GCC (>= 9) demand that the size of the string to be
copied must be explicitly smaller than the size of the destination.
Thus, the NULL char has to be taken into account on strncpy.

This will avoid the following compiling error:

  tlbie_test.c: In function 'main':
  tlbie_test.c:639:4: error: 'strncpy' specified bound 100 equals destination size
      strncpy(logdir, optarg, LOGDIR_NAME_SIZE);
      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  cc1: all warnings being treated as errors

selftests: net: reuseport_dualstack: fix uninitalized parameter

2019-11-10T10:25:28+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

2019-06-22T06:16:16+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

2019-06-19T06:20:57+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

2019-05-16T17:42:24+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

2019-05-16T17:42:23+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.

The changes to fix the CVE 2019-7308 make the bpf verifier stricter
with respect to operations that were allowed earlier in unprivileged
mode. Fixup the test cases so that the error messages now correctly
reflect pointer arithmetic going out of range for tests.
