Subject: [PATCH net 06/10] include: uapi: netfilter_bridge.h: Cover for musl libc
Date: Tue, 17 Feb 2026 17:32:29 +0100 [thread overview]
Message-ID: <20260217163233.31455-7-fw@strlen.de> (raw)
In-Reply-To: <20260217163233.31455-1-fw@strlen.de>
From: Phil Sutter <phil@nwl.cc>
Musl defines its own struct ethhdr and thus defines __UAPI_DEF_ETHHDR to
zero. To avoid struct redefinition errors, user space is therefore
supposed to include netinet/if_ether.h before (or instead of)
linux/if_ether.h. To relieve them from this burden, include the libc
header here if not building for kernel space.
