After merging the net-next tree, today's linux-next build (x86_64 allmodconfig) failed like this: x86_64-linux-ld: unknown architecture of input file `net/bpfilter/bpfilter_umh.o' is incompatible with i386:x86-64 output Caused by commit d2ba09c17a06 ("net: add skeleton of bpfilter kernel module") In my builds, the host is PowerPC 64 LE ... I have reverted that commit along with 61a552eb487f ("bpfilter: fix build dependency") 13405468f49d ("bpfilter: don't pass O_CREAT when opening console for debug") for today.I am still getting this failure (well, at least yesterday I did).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 <redacted> 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 <redacted> --- 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
yeah. that's another option. Sorry for delay. networking folks are traveling to netconf. The issue is being discussed here: https://patchwork.ozlabs.org/patch/921597/ Currently we're thinking how to add a check that hostcc's arch is equal to cross-cc target arch and ideally equal to arch of the host where it will be run.
