Subject: [PATCH v2 4/6] test: fix unsupported BPF instructions in elf load test
Date: Mon, 19 Jan 2026 17:55:07 -0800 [thread overview]
Message-ID: <20260120015759.301155-5-stephen@networkplumber.org> (raw)
In-Reply-To: <20260120015759.301155-1-stephen@networkplumber.org>
The DPDK BPF library only handles the base BPF instructions.
It does not handle JMP32 which would cause the bpf_elf_load
test to fail on clang 20 or later.
Bugzilla ID: 1844
Fixes: cf1e03f881af ("test/bpf: add ELF loading")
Cc: stable@dpdk.org
Signed-off-by: Stephen Hemminger <stephen@networkplumber.org>
Acked-by: Marat Khalili <marat.khalili@huawei.com>
