Subject: [PATCH v2] RDMA/rxe: Generate a completion for unsupported/invalid opcode
Date: Sun, 10 Apr 2022 19:35:13 +0800 [thread overview]
Message-ID: <20220410113513.27537-1-yangx.jy@fujitsu.com> (raw)
Current rxe_requester() doesn't generate a completion when processing an
unsupported/invalid opcode. If rxe driver doesn't support a new opcode
(e.g. RDMA Atomic Write) and RDMA library supports it, an application
using the new opcode can reproduce this issue. Fix the issue by calling
"goto err;".
Fixes: 8700e3e7c485 ("Soft RoCE driver")
