Subject: [PATCH] datapath: unexport LDFLAGS
|
|
|
|
OpenWrt build system will put "-specs=.../hardened-pie-ld.specs" into
|
|
LDFLAGS when building PIE binaries. However the "-specs" argument is
|
|
inteneded for "gcc" the driver while "ld" the linker when presented will
|
|
complain it as unrecognized error.
|
|
|
|
This can cause Kbuild error when building datapath kernel modules. The
|
|
issue should only happen when compiling against upstream kernel 4.14 and
|
|
earlier. Later ones should have been fixed with kernel upstream commit
|
|
d503ac531a5 ("kbuild: rename LDFLAGS to KBUILD_LDFLAGS")
