tools: ynl: extend CFLAGS to keep options from environmentPackage build environments like Fedora rpmbuild introduced hardeningoptions (e.g. -pie -Wl,-z,now) by passing a -spec option to CFLAGSand LDFLAGS.ynl Makefiles currently override CFLAGS but not LDFLAGS, which leadsto a mismatch and build failure: CC sample devlink /usr/bin/ld: devlink.o: relocation R_X86_64_32 against symbol `ynl_devlink_family' can not be used when making a PIE object; recompile with -fPIE /usr/bin/ld: failed to set dynamic section sizes: bad value collect2: error: ld returned 1 exit statusExtend CFLAGS to support hardening options set by build environment.Signed-off-by: Jan Stancek Acked-by: Jakub Kicinski Reviewed-by: Donald Hunter Link: https://patch.msgid.link/265b2d5d3a6d4721a161219f081058ed47dc846a.1731399562.git.jstancek@redhat.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/net/ynl/samples/Makefile

tools: ynl: rename make hardclean -> distcleanThe make target to remove all generated files used to be called"hardclean" because it deleted files which were tracked by git.We no longer track generated user space files, so use the morecommon "distclean" name.Signed-off-by: Jakub Kicinski Reviewed-by: Donald Hunter Signed-off-by: David S.

f0ec58d5 - tools: ynl: work around stale system headers

Wed, 14 Jun 2023 00:28:00 +0000

tools: ynl: work around stale system headersThe inability to include the uAPI headers directly in tools/is one of the bigger annoyances of compiling user space code.Most projects trade the pain for smaller inconvenience of havingto copy the headers under tools/include.In case of netlink headers I think that we can avoid both.Netlink family headers are simple and should be self-contained.We can try to twiddle the Makefile a little to force-includejust the family header, and use system headers for the rest.This works fairly well. There are two warts - for some reasonif we specify -include $path/family.h as a compilation flag,the #ifdef header guard does not seem to work. So we needto throw the guard in on the command line as well. Seems likeGCC detects that the header is different and tries to includeboth. Second problem is that make wants hash sign to be escapedor not depending on the version. Sigh.Signed-off-by: Jakub Kicinski Signed-off-by: David S.
