Subject: [PATCH] netinet/ip.h: Add UAPI definition guard for iphdr
Date: Sun, 22 Dec 2019 00:06:47 -0600	[thread overview]
Message-ID: <20191222060646.7809-1-AWilcox@Wilcox-Tech.com> (raw)

This ensures that the musl definition of 'struct iphdr' does not conflict
with the Linux kernel UAPI definition of it.

Some software, i.e. net-tools, will not compile against 5.4 kernel headers
without this patch and the corresponding Linux kernel patch.
