Subject: [PATCH] alfred: mark alfred_change_bat_iface_v0 as packed
Date: Tue, 28 Jul 2026 19:06:43 +0200	[thread overview]
Message-ID: <20260728-bugfixes-packed-v1-1-5a1888ab4b87@narfation.org> (raw)

struct alfred_change_bat_iface_v0 is part of the unix socket protocol and
is the only protocol structure in packet.h not marked as __packed. The
current members happen to not require any padding, so the layout is
unaffected for common ABIs. But to be safe, also mark this struct as
packed.
