Much of that confusion was around # task_work and TIF_NOTIFY_SIGNAL (which I have now decoupled making the # semantics clearer). # # For people who don't know tracehook.h is a vestiage of an attempt to # implement uprobes like functionality that was never fully merged, and # was later superseeded by uprobes when uprobes was merged. For many # years now we have been removing what tracehook functionaly a little # bit at a time. To the point where anything left in tracehook.h was # some weird strange thing that was difficult to understand" # # * tag 'ptrace-cleanups-for-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: # ptrace: Remove duplicated include in ptrace.c # ptrace: Check PTRACE_O_SUSPEND_SECCOMP permission on PTRACE_SEIZE # ptrace: Return the signal to continue with from ptrace_stop # ptrace: Move setting/clearing ptrace_message into ptrace_stop # tracehook: Remove tracehook.h # resume_user_mode: Move to resume_user_mode.h # resume_user_mode: Remove #ifdef TIF_NOTIFY_RESUME in set_notify_resume # signal: Move set_notify_signal and clear_notify_signal into sched/signal.h # task_work: Decouple TIF_NOTIFY_SIGNAL and task_work # task_work: Call tracehook_notify_signal from get_signal on all architectures # task_work: Introduce task_work_pending # task_work: Remove unnecessary include from posix_timers.h # ptrace: Remove tracehook_signal_handler # ptrace: Remove arch_syscall_{enter,exit}_tracehook # ptrace: Create ptrace_report_syscall_{entry,exit} in ptrace.h # ptrace/arm: Rename tracehook_report_syscall report_syscall # ptrace: Move ptrace_report_syscall into ptrace.h # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 1930a6e739c4b4a654a69164dbe39e554d228915 # < make -s -j 8 ARCH=s390 O=/kisskb/build/linus_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- defconfig # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig # < make -s -j 8 ARCH=s390 O=/kisskb/build/linus_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 8 ARCH=s390 O=/kisskb/build/linus_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- olddefconfig # make -s -j 8 ARCH=s390 O=/kisskb/build/linus_s390-defconfig_s390x-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/s390-linux/bin/s390-linux- /kisskb/src/arch/s390/kernel/machine_kexec.c: In function '__do_machine_kdump': /kisskb/src/arch/s390/kernel/machine_kexec.c:57:9: warning: 'memcpy' offset [0, 511] is out of the bounds [0, 0] [-Warray-bounds] 57 | memcpy((void *) __LC_FPREGS_SAVE_AREA, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 58 | (void *)(prefix + __LC_FPREGS_SAVE_AREA), 512); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/linus_s390-defconfig_s390x-gcc11 # Build took: 0:09:21.979181
