Subject: [PATCH v2 0/3] fix function type mismatches in syscall wrappers
Date: Fri, 3 May 2019 12:12:22 -0700 [thread overview]
Message-ID: <20190503191225.6684-1-samitolvanen@google.com> (raw)
These patches fix type mismatches in arm64 syscall wrapper
definitions, which trip indirect call checks with Control-Flow
Integrity.
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
