There are three head files(kallsyms.h, kernel.h and sections.h) which include the kernel sections range check, let's make some cleanup and unify them. 1. cleanup arch specific text/data check and fix address boundary check in kallsyms.h 2. make all the basic/core kernel range check function into sections.h 3. update all the callers, and use the helper in sections.h to simplify the code After this series, we have 5 APIs about kernel sections range check in sections.h * is_kernel_core_data() --- come from core_kernel_data() in kernel.h * is_kernel_rodata() --- already in sections.h * is_kernel_text() --- come from kallsyms.h * is_kernel_inittext() --- come from kernel.h and kallsyms.h * is_kernel() --- come from kallsyms.h Cc: linuxppc-dev@xxxxxxxxxxxxxxxx Cc: linux-s390@xxxxxxxxxxxxxxx Cc: linux-arch@xxxxxxxxxxxxxxx Cc: iommu@xxxxxxxxxxxxxxxxxxxxxxxxxx Cc: bpf@xxxxxxxxxxxxxxx v2: - add ACK/RW to patch2, and drop inappropriate fix tag - keep 'core' to check kernel data, suggestted by Steven Rostedt <rostedt@xxxxxxxxxxx>, rename is_kernel_data() to is_kernel_core_data() - drop patch8 which is merged - drop patch9 which is resend independently v1: https://lore.kernel.org/linux-arch/20210626073439.150586-1-wangkefeng.wang@xxxxxxxxxx Kefeng Wang (7): kallsyms: Remove arch specific text and data check kallsyms: Fix address-checks for kernel related range sections: Move and rename core_kernel_data() to is_kernel_core_data() sections: Move is_kernel_inittext() into sections.h kallsyms: Rename is_kernel() and is_kernel_text() sections: Add new is_kernel() and is_kernel_text() powerpc/mm: Use is_kernel_text() and is_kernel_inittext() helper arch/powerpc/mm/pgtable_32.c | 7 +--- arch/x86/kernel/unwind_orc.c | 2 +- arch/x86/net/bpf_jit_comp.c | 2 +- include/asm-generic/sections.h | 71 ++++++++++++++++++++++++++-------- include/linux/kallsyms.h | 21 +++------- include/linux/kernel.h | 2 - kernel/cfi.c | 2 +- kernel/extable.c | 33 ++-------------- kernel/locking/lockdep.c | 3 -- kernel/trace/ftrace.c | 2 +- mm/kasan/report.c | 2 +- net/sysctl_net.c | 2 +- 12 files changed, 72 insertions(+), 77 deletions(-) -- 2.26.2
