| # This file is used to populate seccomp's whitelist policy in combination with SYSCALLS.TXT. |
| # Note that the resultant policy is applied only to zygote spawned processes. |
| # |
| # Each non-blank, non-comment line has the following format: |
| # |
| # return_type func_name[|alias_list][:syscall_name[:socketcall_id]]([parameter_list]) arch_list |
| # |
| # where: |
| # arch_list ::= "all" | arch+ |
| # arch ::= "arm" | "arm64" | "mips" | "mips64" | "x86" | "x86_64" |
| # |
| # Note: |
| # - syscall_name corresponds to the name of the syscall, which may differ from |
| # the exported function name (example: the exit syscall is implemented by the _exit() |
| # function, which is not the same as the standard C exit() function which calls it) |
| |
| # - alias_list is optional comma separated list of function aliases |
| # |
| # - The call_id parameter, given that func_name and syscall_name have |
| # been provided, allows the user to specify dispatch style syscalls. |
| # For example, socket() syscall on i386 actually becomes: |
| # socketcall(__NR_socket, 1, *(rest of args on stack)). |
| # |
| # - Each parameter type is assumed to be stored in 32 bits. |
| # |
| # This file is processed by a python script named genseccomp.py. |
