1# This file is used to populate seccomp's whitelist policy in combination with SYSCALLS.TXT.
2# Note that the resultant policy is applied only to zygote spawned processes.
3#
4# Each non-blank, non-comment line has the following format:
5#
6# return_type func_name[|alias_list][:syscall_name[:socketcall_id]]([parameter_list]) arch_list
7#
8# where:
9#       arch_list ::= "all" | arch+
10#       arch      ::= "arm" | "arm64" | "mips" | "mips64" | "x86" | "x86_64"
11#
12# Note:
13#      - syscall_name corresponds to the name of the syscall, which may differ from
14#        the exported function name (example: the exit syscall is implemented by the _exit()
15#        function, which is not the same as the standard C exit() function which calls it)
16
17#      - alias_list is optional comma separated list of function aliases
18#
19#      - The call_id parameter, given that func_name and syscall_name have
20#        been provided, allows the user to specify dispatch style syscalls.
21#        For example, socket() syscall on i386 actually becomes:
22#          socketcall(__NR_socket, 1, *(rest of args on stack)).
23#
24#      - Each parameter type is assumed to be stored in 32 bits.
