Subject: [RFC PATCH dlm/next 3/4] dlm: reject SCTP configuration if not enabled
Date: Tue, 29 Apr 2025 16:29:12 -0400	[thread overview]
Message-ID: <20250429202913.2908521-3-aahringo@redhat.com> (raw)
In-Reply-To: <20250429202913.2908521-1-aahringo@redhat.com>

Reject SCTP dlm configuration if the kernel was never build with SCTP.
Currently the only one known user space tool "dlm_controld" will drop an
error in the logs and getting stuck. This behaviour should be fixed to
deliver an error to the user or fallback to TCP.
