Subject: [PATCH net 12/17] selftests: forwarding: tc_flower: Relax success criterion
Date: Wed, 2 Aug 2023 10:51:13 +0300	[thread overview]
Message-ID: <20230802075118.409395-13-idosch@nvidia.com> (raw)
In-Reply-To: <20230802075118.409395-1-idosch@nvidia.com>

The test checks that filters that match on source or destination MAC
were only hit once. A host can send more than one packet with a given
source or destination MAC, resulting in failures.

Fix by relaxing the success criterion and instead check that the filters
were not hit zero times. Using tc_check_at_least_x_packets() is also an
option, but it is not available in older kernels.

Fixes: 07e5c75184a1 ("selftests: forwarding: Introduce tc flower matching tests")
Reported-by: Mirsad Todorovac <mirsad.todorovac@alu.unizg.hr>
Closes: https://lore.kernel.org/netdev/adc5e40d-d040-a65e-eb26-edf47dac5b02@alu.unizg.hr/
