Subject: [PATCH] bpf: BPF_SYSCALL depends INET
Date: Thu, 23 Jul 2020 07:19:14 -0700 [thread overview]
Message-ID: <20200723141914.20722-1-trix@redhat.com> (raw)
From: Tom Rix <trix@redhat.com>
A link error
kernel/bpf/net_namespace.o: In function `bpf_netns_link_release':
net_namespace.c: undefined reference to `bpf_sk_lookup_enabled'
bpf_sk_lookup_enabled is defined with INET
net_namespace is controlled by BPF_SYSCALL
So add a depends on INET to BPF_SYSCALL
