treewide: prefix header search paths with $(srctree)/

2019-05-18T02:49:57+00:00

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].

To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.

Having whitespaces after -I does not matter since commit 48f6e3cf5bc6
("kbuild: do not drop -I without parameter").

bpfilter: re-add header search paths to tools include to fix build error

2019-02-23T21:34:40+00:00

I thought header search paths to tools/include(/uapi) were unneeded,
but it looks like a build error occurs depending on the compiler.

Commit 303a339f30a9 ("bpfilter: remove extra header search paths for
bpfilter_umh") reintroduced the build error fixed by commit ae40832e53c3
("bpfilter: fix a build err").

Apology for the breakage, and thanks to Guenter for reporting this.

bpfilter: remove extra header search paths for bpfilter_umh

2019-02-04T04:11:43+00:00

Currently, the header search paths -Itools/include and
-Itools/include/uapi are not used. Let's drop the unused code.

We can remove -I. too by fixing up one C file.

kbuild: Rename HOSTLDFLAGS to KBUILD_HOSTLDFLAGS

2018-07-17T16:18:05+00:00

In preparation for enabling command line LDFLAGS, re-name HOSTLDFLAGS
to KBUILD_HOSTLDFLAGS as the internal use only flags. This should not
have any visible effects.

bpfilter: include bpfilter_umh in assembly instead of using objcopy

2018-06-28T12:39:16+00:00

What we want here is to embed a user-space program into the kernel.
Instead of the complex ELF magic, let's simply wrap it in the assembly
with the '.incbin' directive.

bpfilter: fix user mode helper cross compilation

2018-06-21T00:19:19+00:00

Use $(OBJDUMP) instead of literal 'objdump' to avoid
using host toolchain when cross compiling.

bpfilter: fix build error

2018-06-20T00:07:46+00:00

bpfilter Makefile assumes that the system locale is en_US, and the
parsing of objdump output fails.
Set LC_ALL=C and, while at it, rewrite the objdump parsing so it spawns
only 2 processes instead of 7.

bpfilter: fix OUTPUT_FORMAT

CONFIG_OUTPUT_FORMAT is x86 only macro.
Used objdump to extract elf file format.

bpfilter: switch to CC from HOSTCC

2018-06-05T14:21:18+00:00

check that CC can build executables and use that compiler instead of HOSTCC
