selftests: forwarding: Fix race condition in mirror installation

2023-06-28T09:14:16+00:00

[ Upstream commit c7c059fba6fb19c3bc924925c984772e733cb594 ]

When mirroring to a gretap in hardware the device expects to be
programmed with the egress port and all the encapsulating headers. This
requires the driver to resolve the path the packet will take in the
software data path and program the device accordingly.

If the path cannot be resolved (in this case because of an unresolved
neighbor), then mirror installation fails until the path is resolved.
This results in a race that causes the test to sometimes fail.

Fix this by setting the neighbor's state to permanent in a couple of
tests, so that it is always valid.

selftests: net: fcnal-test: check if FIPS mode is enabled

2023-06-28T09:14:12+00:00

[ Upstream commit d7a2fc1437f71cb058c7b11bc33dfc19e4bf277a ]

There are some MD5 tests which fail when the kernel is in FIPS mode,
since MD5 is not FIPS compliant. Add a check and only run those tests
if FIPS mode is not enabled.

selftests: net: vrf-xfrm-tests: change authentication and encryption algos

2023-06-28T09:14:12+00:00

[ Upstream commit cb43c60e64ca67fcc9d23bd08f51d2ab8209d9d7 ]

The vrf-xfrm-tests tests use the hmac(md5) and cbc(des3_ede)
algorithms for performing authentication and encryption, respectively.
This causes the tests to fail when fips=1 is set, since these algorithms
are not allowed in FIPS mode. Therefore, switch from hmac(md5) and
cbc(des3_ede) to hmac(sha1) and cbc(aes), which are FIPS compliant.

selftests: mptcp: join: skip mixed tests if not supported

2023-06-28T09:14:04+00:00

commit 6673851be0fc1bfc3353ffb52ff26ae5468f12c9 upstream.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.

One of them is the support of a mix of subflows in v4 and v6 by the
in-kernel PM introduced by commit b9d69db87fb7 ("mptcp: let the
in-kernel PM use mixed IPv4 and IPv6 addresses").

It looks like there is no external sign we can use to predict the
expected behaviour. Instead of accepting different behaviours and thus
not really checking for the expected behaviour, we are looking here for
a specific kernel version. That's not ideal but it looks better than
removing the test because it cannot support older kernel versions.

selftests: mptcp: join: uniform listener tests

2023-06-28T09:14:03+00:00

commit 96b84195df61d374d8028cf426a115ae085031ec upstream.

The alignment was different from the other tests because tabs were used
instead of spaces.

While at it, also use 'echo' instead of 'printf' to print the result to
keep the same style as done in the other sub-tests. And, even if it
should be better with, also remove 'stdbuf' and sed's '--unbuffered'
option because they are not used in the other subtests and they are not
available when using a minimal environment with busybox.
