[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.

kernel leftovers in /boot/efi/EFI/Linux/
by Germano Massullo 05 Apr '24

05 Apr '24

Hello, during a dnf update I noticed that /boot/efi was full and the system was not able to update. So I found out in /boot/efi/EFI/Linux/ there are many files belonging to kernel RPMs no longer installed on the system. I am wondering why there are these leftovers. Some of the kernel with .fc39.1 in their name are from RPMs I created to test kernel patches, but they don't have anything special compared to regular Fedora kernel RPMs, since I just rebuilt the package after having added a patch. root@machine:/home/user# eza -lah /boot/efi/EFI/Linux/ Permissions Size User Date Modified Name .rwx------@ 61M root 11 dic 2023 3fca3f6e08d1481a961d4954bff61ddf-6.6.4-100.fc39.1.x86_64+debug.efi .rwx------@ 44M root 11 dic 2023 3fca3f6e08d1481a961d4954bff61ddf-6.6.4-100.fc39.1.x86_64.efi .rwx------@ 61M root 11 dic 2023 3fca3f6e08d1481a961d4954bff61ddf-6.6.4-200.fc39.x86_64+debug.efi .rwx------@ 44M root 11 dic 2023 3fca3f6e08d1481a961d4954bff61ddf-6.6.4-200.fc39.x86_64.efi .rwx------@ 62M root 13 dic 2023 3fca3f6e08d1481a961d4954bff61ddf-6.6.6-200.fc39.1.x86_64+debug.efi .rwx------@ 44M root 13 dic 2023 3fca3f6e08d1481a961d4954bff61ddf-6.6.6-200.fc39.1.x86_64.efi .rwx------@ 61M root 20 dic 2023 3fca3f6e08d1481a961d4954bff61ddf-6.6.6-200.fc39.x86_64+debug.efi .rwx------@ 62M root 17 dic 2023 3fca3f6e08d1481a961d4954bff61ddf-6.6.6-201.fc39.1.x86_64+debug.efi .rwx------@ 44M root 17 dic 2023 3fca3f6e08d1481a961d4954bff61ddf-6.6.6-201.fc39.1.x86_64.efi .rwx------@ 1,2M root 20 dic 2023 3fca3f6e08d1481a961d4954bff61ddf-6.6.7-200.fc39.x86_64+debug.efi .rwx------@ 0 root 31 dic 2023 3fca3f6e08d1481a961d4954bff61ddf-6.6.8-200.fc39.x86_64+debug.efi .rwx------@ 0 root 7 gen 00:31 3fca3f6e08d1481a961d4954bff61ddf-6.6.9-200.fc39.x86_64+debug.efi .rwx------@ 0 root 16 gen 11:04 3fca3f6e08d1481a961d4954bff61ddf-6.6.11-200.fc39.x86_64+debug.efi .rwx------@ 0 root 24 gen 20:44 3fca3f6e08d1481a961d4954bff61ddf-6.6.12-200.fc39.x86_64+debug.efi .rwx------@ 0 root 26 gen 23:15 3fca3f6e08d1481a961d4954bff61ddf-6.6.13-200.fc39.x86_64+debug.efi .rwx------@ 0 root 4 feb 17:50 3fca3f6e08d1481a961d4954bff61ddf-6.6.14-200.fc39.x86_64+debug.efi root@machine:/home/user# rpm -q kernel kernel-6.6.12-200.fc39.x86_64 kernel-6.6.13-200.fc39.x86_64 kernel-6.6.14-200.fc39.x86_64

[OS-BUILD PATCHv5 0/2] redhat/kernel.spec: add uki_addons to create UKI kernel cmdline addons
by Emanuele Giuseppe Esposito (via Email Bridge) 08 Mar '24

08 Mar '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/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/addons and call 'ukify' to create the actual addons. The output addon filename will be a concatenation of all folders in redhat/addons that are part of the addon config path. For example, an addon config redhat/addons/1/2/3/test.addon will result in generating redhat/addons_output/1-2-3-test.addon.efi. It is also possible to add .sbat to all the generated addons, by populating redhat/addons/sbat/sbat.conf. Syntax is same as the addons config. At build time, Makefile will create a tar.gz archive (addons.tar.gz) containing all the files in redhat/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/addons/sbat/.gitkeep | 0 redhat/addons/fips.addon | 2 + redhat/scripts/uki_addons.py | 124 +++++++++++++++++++++++++++++++++++++++++++ redhat/Makefile | 3 + redhat/kernel.spec.template | 18 ++++++ 5 files changed, 147 insertions(+), 0 deletions(-)

[OS-BUILD PATCH 0/0] rcutorture: Also force sched priority to timersd on boosting test.
by Don Zickus (via Email Bridge) 28 Feb '24

28 Feb '24

From: Don Zickus on gitlab.com Merge Request: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/2963 NOTE: Truncated patchset since committer email 'bigeasy(a)linutronix.de' does not match the submitter's GitLab public email address 'dzickus(a)redhat.com'. ksoftirqd is statically boosted to the priority level right above the one of rcu_torture_boost() so that timers, which torture readers rely on, get a chance to run while rcu_torture_boost() is polling. However timers processing got split from ksoftirqd into their own kthread (timersd) that isn't boosted. It has the same SCHED_FIFO low prio as rcu_torture_boost() and therefore timers can't preempt it and may starve. The issue can be triggered in practice on v5.17.1-rt17 using: ./kvm.sh --allcpus --configs TREE04 --duration 10m --kconfig "CONFIG_EXPERT=y CONFIG_PREEMPT_RT=y" Fix this with statically boosting timersd just like is done with ksoftirqd in commit ea6d962e80b61 ("rcutorture: Judge RCU priority boosting on grace periods, not callbacks") Suggested-by: Mel Gorman <mgorman(a)suse.de> Cc: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> Cc: Thomas Gleixner <tglx(a)linutronix.de> Signed-off-by: Frederic Weisbecker <frederic(a)kernel.org> Link: https://lkml.kernel.org/r/20220405010752.1347437-1-frederic@kernel.org Signed-off-by: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> --- Documentation/admin-guide/kernel-parameters.txt | 12 + arch/arm/mm/fault.c | 6 + arch/arm/vfp/vfpmodule.c | 74 +- arch/arm/Kconfig | 6 +- arch/arm64/Kconfig | 1 + arch/powerpc/include/asm/stackprotector.h | 7 +- arch/powerpc/kernel/traps.c | 7 +- arch/powerpc/kvm/Kconfig | 1 + arch/powerpc/platforms/pseries/Kconfig | 1 + arch/powerpc/platforms/pseries/iommu.c | 31 +- arch/powerpc/Kconfig | 2 + arch/riscv/include/asm/thread_info.h | 2 + arch/riscv/Kconfig | 2 + arch/x86/include/asm/thread_info.h | 6 +- arch/x86/Kconfig | 3 + drivers/acpi/processor_idle.c | 2 +- drivers/block/zram/zram_drv.c | 37 + drivers/block/zram/zram_drv.h | 3 + drivers/gpu/drm/i915/display/intel_crtc.c | 15 +- drivers/gpu/drm/i915/display/intel_vblank.c | 38 +- drivers/gpu/drm/i915/gt/uc/intel_guc.h | 2 +- drivers/gpu/drm/i915/gt/intel_breadcrumbs.c | 5 +- drivers/gpu/drm/i915/gt/intel_execlists_submission.c | 17 +- drivers/gpu/drm/i915/Kconfig | 1 - drivers/gpu/drm/i915/i915_request.c | 2 - drivers/gpu/drm/i915/i915_trace.h | 6 +- drivers/gpu/drm/i915/i915_utils.h | 2 +- drivers/tty/serial/8250/8250_core.c | 42 +- drivers/tty/serial/8250/8250_port.c | 160 +++- drivers/tty/serial/amba-pl011.c | 12 +- drivers/tty/serial/omap-serial.c | 12 +- drivers/tty/tty_io.c | 9 +- fs/proc/consoles.c | 14 +- include/linux/sched/idle.h | 8 +- include/linux/bottom_half.h | 2 + include/linux/console.h | 127 ++- include/linux/entry-common.h | 2 +- include/linux/entry-kvm.h | 2 +- include/linux/interrupt.h | 29 + include/linux/netdevice.h | 4 + include/linux/printk.h | 32 +- include/linux/sched.h | 13 +- include/linux/serial_8250.h | 6 + include/linux/serial_core.h | 31 +- include/linux/thread_info.h | 24 + include/linux/trace_events.h | 8 +- kernel/entry/common.c | 4 +- kernel/entry/kvm.c | 2 +- kernel/locking/lockdep.c | 5 + kernel/printk/internal.h | 98 + kernel/printk/nbcon.c | 732 +++++++++++++- kernel/printk/printk.c | 675 ++++++++++-- kernel/printk/printk_ringbuffer.c | 335 +++++- kernel/printk/printk_ringbuffer.h | 54 +- kernel/printk/printk_safe.c | 12 + kernel/rcu/rcutorture.c | 6 + kernel/rcu/tree_stall.h | 5 + kernel/sched/core.c | 65 +- kernel/sched/debug.c | 19 + kernel/sched/fair.c | 46 +- kernel/sched/features.h | 2 + kernel/sched/idle.c | 3 +- kernel/sched/rt.c | 5 +- kernel/sched/sched.h | 1 + kernel/time/hrtimer.c | 4 +- kernel/time/tick-sched.c | 2 +- kernel/time/timer.c | 11 +- kernel/trace/trace.c | 2 + kernel/trace/trace_output.c | 16 +- kernel/Kconfig.preempt | 17 +- kernel/ksysfs.c | 12 + kernel/panic.c | 17 + kernel/softirq.c | 95 +- lib/dump_stack.c | 16 +- net/core/dev.c | 39 +- net/core/skbuff.c | 7 +- redhat/configs/pending-fedora/generic/CONFIG_PREEMPT_AUTO | 15 + redhat/configs/pending-fedora/generic/CONFIG_PREEMPT_RT | 15 + redhat/configs/rhel/generic/CONFIG_PREEMPT_AUTO | 1 + redhat/configs/rhel/generic/CONFIG_PREEMPT_RT | 1 + redhat/configs/rhel/rt/debug/CONFIG_PREEMPT_VOLUNTARY | 1 - redhat/configs/rhel/rt/generic/CONFIG_PREEMPT_DYNAMIC | 2 +- redhat/configs/rhel/rt/generic/CONFIG_PREEMPT_RT | 2 +- redhat/configs/rhel/rt/generic/CONFIG_PREEMPT_VOLUNTARY | 2 +- localversion-rt | 1 + 85 files changed, 2740 insertions(+), 435 deletions(-)
