selftests: tpm: Use /bin/sh instead of /bin/bash

2020-07-09T07:37:51+00:00

commit 377ff83083c953dd58c5a030b3c9b5b85d8cc727 upstream.

It's better to use /bin/sh instead of /bin/bash in order to run the tests
in the BusyBox shell.

selftests/net: report etf errors correctly

2020-06-30T19:36:58+00:00

[ Upstream commit ca8826095e4d4afc0ccaead27bba6e4b623a12ae ]

The ETF qdisc can queue skbs that it could not pace on the errqueue.

Address a few issues in the selftest

- recv buffer size was too small, and incorrectly calculated
- compared errno to ee_code instead of ee_errno
- missed invalid request error type

v2:
  - fix a few checkpatch --strict indentation warnings

selftests/net: in timestamping, strncpy needs to preserve null byte

2020-06-24T15:50:41+00:00

[ Upstream commit 8027bc0307ce59759b90679fa5d8b22949586d20 ]

If user passed an interface option longer than 15 characters, then
device.ifr_name and hwtstamp.ifr_name became non-null-terminated
strings. The compiler warned about this:

timestamping.c:353:2: warning: ‘strncpy’ specified bound 16 equals \
destination size [-Wstringop-truncation]
  353 |  strncpy(device.ifr_name, interface, sizeof(device.ifr_name));

NTB: ntb_test: Fix bug when counting remote files

2020-06-24T15:50:41+00:00

[ Upstream commit 2130c0ba69d69bb21f5c52787f2587db00d13d8a ]

When remote files are counted in get_files_count, without using SSH,
the code returns 0 because there is a colon prepended to $LOC. $VPATH
should have been used instead of $LOC.

selftests/vm/pkeys: fix alloc_random_pkey() to make it really random

2020-06-24T15:50:39+00:00

[ Upstream commit 6e373263ce07eeaa6410843179535fbdf561fc31 ]

alloc_random_pkey() was allocating the same pkey every time.  Not all
pkeys were geting tested.  This fixes it.

selftests/bpf, flow_dissector: Close TAP device FD after the test

2020-06-22T07:31:12+00:00

[ Upstream commit b8215dce7dfd817ca38807f55165bf502146cd68 ]

test_flow_dissector leaves a TAP device after it's finished, potentially
interfering with other tests that will run after it. Fix it by closing the
TAP descriptor on cleanup.
