Still happened today. My guess is that bpfilter_umh needs to be built with the kernel compiler (not the host compiler - since ir is meant to run on the some machine as the kernel, right?) but will require the kernel architecture libc etc I replaced the reverts above with the following: From: Stephen Rothwell Date: Fri, 1 Jun 2018 13:33:28 +1000 Subject: [PATCH] net: bpfilter: mark as BROKEN for now This does not build in a cross compile environment Signed-off-by: Stephen Rothwell --- net/bpfilter/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/net/bpfilter/Kconfig b/net/bpfilter/Kconfig index a948b072c28f..ea4be72fdf6e 100644 --- a/net/bpfilter/Kconfig +++ b/net/bpfilter/Kconfig @@ -2,6 +2,7 @@ menuconfig BPFILTER bool "BPF based packet filtering framework (BPFILTER)" default n depends on NET && BPF && INET + depends on BROKEN help This builds experimental bpfilter framework that is aiming to provide netfilter compatible functionality via BPF -- 2.17.0 -- Cheers, Stephen Rothwell
