Unable to compile linux-kernel pulled from nf-next tree
Hello, I'm working on a task in netfilter and trying to compile linux-kernel pulled from nf-next tree. https://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next.git but fail with these errors. make-- Kernel: arch/x86/boot/bzImage is ready (#4) MODPOST 4905 modules fs/ufs/ufs.o: Invalid argument scripts/Makefile.modpost:92: recipe for target '__modpost' failed make[1]: *** [__modpost] Error 1 Makefile:1211: recipe for target 'modules' failed make: *** [modules] Error 2 sudo make modules_install install-- cp: cannot stat 'net/nsh/nsh.ko': No such file or directory At main.c:291: - SSL error:02001002:system library:fopen:No such file or directory: bss_file.c:175 - SSL error:2006D080:BIO routines:BIO_new_file:no such file: bss_file.c:178 sign-file: /lib/modules/4.14.0-rc8+/kernel/net/nsh/nsh.ko: No such file or directory scripts/Makefile.modinst:36: recipe for target 'net/nsh/nsh.ko' failed make[2]: *** [net/nsh/nsh.ko] Error 1 Makefile:1232: recipe for target '_modinst_' failed make[1]: *** [_modinst_] Error 2 Makefile:527: recipe for target '__build_one_by_one' failed make: *** [__build_one_by_one] Error 2 Any help will be appreciated.

You should let the netfilter developers know this, not much we can do here, perhaps their branch is broken at the moment :( thanks, greg k-h

There was almost certainly a compile error for this. Go back and look at the 'make' output.
make |& tee build.output is your friend.

You didn't fill up the filesystem you were building in, did you? If you're using a .config that builds 4,900+ modules, that's going to chew disk like crazy, especially if you have CONFIG_DEBUG_KERNEL=y so all of them are built with 'gcc -g'.... (You may want to consider doing a 'make localmodconfig' so it bypasses the 3,500 or more modules that don't apply to your hardware/software config...)

Using `make localmodconfig` doesn't load module nfnetlink in which I'm making the changes. What can be the best way to have a config that builds least but all required modules ? Using `make localmodconfig` don't produces these errors as these modules are no more build. Thanks for your time :)

'make localmodconfig' simply uses the output of 'lsmod' - so if you want nfnetlink included, simply modprobe a module called nfnetlink before you run it. If you're doing a totally new module, it doesn't have to *work*, it just has to modprobe or insmod successfully. Also, make sure you plug in all your USB widgets and devices to make sure they get modprobe'd as well.
