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. 25 # 26 # This file is processed by a python script named genseccomp.py. 27 28 # b/34651972 29 int access:access(const char *pathname, int mode) arm,x86,mips 30 int stat64:stat64(const char*, struct stat64*) arm,x86,mips 31 32 # b/34719286 33 int eventfd:eventfd(unsigned int initval, int flags) arm,x86,mips 34 35 # b/34817266 36 int epoll_wait:epoll_wait(int epfd, struct epoll_event *events, int maxevents, int timeout) arm,x86,mips 37 38 # b/34908783 39 int epoll_create:epoll_create(int size) arm,x86,mips 40 41 # b/34979910 42 int creat:creat(const char *pathname, mode_t mode) arm,x86,mips 43 int unlink:unlink(const char *pathname) arm,x86,mips 44 45 # b/35059702 46 int lstat64:lstat64(const char*, struct stat64*) arm,x86,mips 47 48 # b/35217603 49 int fcntl:fcntl(int fd, int cmd, ... /* arg */ ) arm,x86,mips 50 pid_t fork:fork() arm,x86,mips 51 int poll:poll(struct pollfd *fds, nfds_t nfds, int timeout) arm,x86,mips 52 53 # b/35906875.
