These patches fix type mismatches in arm64 syscall wrapper definitions, which trip indirect call checks with Control-Flow Integrity.
Changes in v3: - instead of SYSCALL_DEFINE0, just define __arm64_sys_ni_syscall with the correct type to avoid unnecessary error injection Changes in v2: - more informative commit message for the syscall_fn_t change - added a patch for fixing sys_ni_syscall Sami Tolvanen (3): arm64: fix syscall_fn_t type arm64: use the correct function type in SYSCALL_DEFINE0 arm64: use the correct function type for __arm64_sys_ni_syscall arch/arm64/include/asm/syscall.h | 2 +- arch/arm64/include/asm/syscall_wrapper.h | 18 +++++++++--------- arch/arm64/kernel/sys.c | 14 +++++++++----- arch/arm64/kernel/sys32.c | 7 ++----- 4 files changed, 21 insertions(+), 20 deletions(-) -- 2.22.0.rc1.257.g3120a18244-goog
