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# The final seccomp whitelist is SYSCALLS.TXT - SECCOMP_BLACKLIST.TXT + SECCOMP_WHITELIST.TXT 5# Any entry in the blacklist must be in the syscalls file and not be in the whitelist file 6# 7# Each non-blank, non-comment line has the following format: 8# 9# return_type func_name[|alias_list][:syscall_name[:socketcall_id]]([parameter_list]) arch_list 10# 11# where: 12# arch_list ::= "all" | arch+ 13# arch ::= "arm" | "arm64" | "mips" | "mips64" | "x86" | "x86_64" 14# 15# Note: 16# - syscall_name corresponds to the name of the syscall, which may differ from 17# the exported function name (example: the exit syscall is implemented by the _exit() 18# function, which is not the same as the standard C exit() function which calls it) 19 20# - alias_list is optional comma separated list of function aliases 21# 22# - The call_id parameter, given that func_name and syscall_name have 23# been provided, allows the user to specify dispatch style syscalls. 24# For example, socket() syscall on i386 actually becomes: 25# socketcall(__NR_socket, 1, *(rest of args on stack)). 26# 27# - Each parameter type is assumed to be stored in 32 bits. 28# 29# This file is processed by a python script named genseccomp.py. 30 31int swapon(const char*, int) all 32int swapoff(const char*) all 33
