[OS-BUILD PATCH] Add wildcard macros -baseonly -gcov
by Don Zickus (via Email Bridge) 18 Sep '24

18 Sep '24

From: Don Zickus <dzickus(a)redhat.com> Add wildcard macros -baseonly -gcov There are multiple usecases for -baseonly and -gcov on various targets in the Makefile. Instead of calling those targets out repeatedly, lets generalize them a bit. Allow adding -baseonly and -gcov to: dist-rpm dist-srpm dist-brew dist-koji distg-brew distg-koji Gcov is useful for adding code coverage. Baseonly is useful to only build the kernel for debugging purposes without userspace tools.

[OS-BUILD PATCHv2] Fix binutils breakage
by Don Zickus (via Email Bridge) 15 Aug '24

15 Aug '24

From: Don Zickus <dzickus(a)redhat.com> Fix binutils breakage The binutils package in Rawhide has stricter checks about PIE/PIC code and will start reporting errors if it detects mixing and matching no-PIE with PIE binaries (especially around bpf binaries). Example errors look like: /usr/bin/ld: /tmp/ccL7dkfR.o: relocation R_X86_64_32S against `.rodata' 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 status Fix this by adding more CFLAGS to force PIE/PIC generated binaries to bpf releated selftests, tools and samples. This patch was provided by Carlos O'Donell and understands how it works. I am just the middle man. All -fPIE errors are resolved except for one about libbpf.a. The static version of the library doesn't take CFLAGS so it can't be forced to build with PIE/PIC. This error is ignored by the spec file, so it is ignored by this patch too.

[OS-BUILD PATCHv17 0/2] redhat/kernel.spec: add uki_addons to create UKI kernel cmdline addons
by Emanuele Giuseppe Esposito (via Email Bridge) 05 Aug '24

05 Aug '24

From: Emanuele Giuseppe Esposito on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/2917 We want to enable kernel.spec to optionally ship UKI addons defined in a common config file in redhat folder. The folder redhat/uki_addons will contain all addons configs specifying the UKI kernel cmdline addons to be created in the next build. An addon config is simply a .addon plain text file, where any line is taken as kernel cmdline, except for the ones starting with '#', which will be automatically ignored. redhat/scripts/uki_addons.py will take care of parsing all configs and folders in redhat/uki_addons and call 'ukify' to create the actual addons. The output addon filename will be a concatenation of all folders in redhat/uki_addons that are part of the addon config path. The folder hierarchy inside of redhat/uki_addons is similar to redhat/configs: $distro/$UKI_NAME/%arch. It is also possible to add .sbat to all the generated addons, by populating redhat/addons/$distro/$UKI_NAME/%arch/sbat/sbat.conf. Syntax is same as the addons config. At build time, Makefile will create a tar.gz archive (uki_addons.tar.gz) containing all the files in redhat/uki_addons. It will then passed to the kernel specfile that will extract the addons from it and generate the UKI kernel cmdline addons. As an example of this feature, add the fips addon to optionally enable fips (https://issues.redhat.com/browse/RHEL-23049) --- redhat/scripts/uki_addons.py | 162 +++++++++++++++++++++++++++++++ redhat/uki_addons/virt/common/fips.addon | 1 + redhat/Makefile | 3 + redhat/kernel.spec.template | 44 ++++++++ 4 files changed, 210 insertions(+), 0 deletions(-)

Building upstream kernel with Fedora config
by Mikhail Gavrilov 24 Jun '24

24 Jun '24

Hi, Instruction [1] about building upstream kernel should be updated, because since commit 5e6abd7f4dce [2] the Fedora kernel config contain CONFIG_SYSTEM_TRUSTED_KEYS="certs/rhel.pem" and this is lead to build error: HOSTCC /home/mikhail/packaging-work/git/linux/tools/bpf/resolve_btfids/ctype.o HOSTCC /home/mikhail/packaging-work/git/linux/tools/bpf/resolve_btfids/str_error_r.o HOSTLD /home/mikhail/packaging-work/git/linux/tools/bpf/resolve_btfids/resolve_btfids-in.o LINK resolve_btfids make[3]: *** No rule to make target 'certs/rhel.pem', needed by 'certs/x509_certificate_list'. Stop. make[3]: *** Waiting for unfinished jobs.... I always use Fedora current kernel config for bisecting upstream kernel. Not sure if my solution is right. But for a quick workaround I decided to remove CONFIG_SYSTEM_TRUSTED_KEYS value.
