Subject: [PATCH bpf-next v2 12/12] selftests/bpf: Add tests for by-value kfunc arguments
Date: Tue, 8 Sep 2026 23:26:26 -0700 [thread overview]
Message-ID: <20260909062626.4009860-1-yonghong.song@linux.dev> (raw)
In-Reply-To: <20260909062522.4001896-1-yonghong.song@linux.dev>
Add kfuncs taking a 16-byte struct and an __int128 by value, with
combinations of <= 8 byte arguments and '> 8 && <= 16' byte arguments,
and tests that call them. Each checks the value the kfunc returns, so a
misplaced argument shows up rather than passing quietly.
Between them the cases cover an argument the two conventions place
alike, one arm64 moves between registers, one an ABI moves to or from
the stack, and one both ABIs pad the stack for. All of them run on both
arches; what differs is how many instructions the JIT emits to get
there. Two more cover the rejections that hold everywhere, an aggregate
holding a pointer and one too large to pass by value.
test_stack_arg_big() in stack_arg_fail.c passed a 16-byte struct as the
sixth argument and asserted the unrecognized stack argument type it used
to be reported as. The JIT places that argument now, so the test is
removed and the same call is covered by the cases above.
