# 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. # b/34651972 int access:access(const char *pathname, int mode) arm,x86,mips int stat64:stat64(const char*, struct stat64*) arm,x86,mips # b/34719286 int eventfd:eventfd(unsigned int initval, int flags) arm,x86,mips # b/34817266 int epoll_wait:epoll_wait(int epfd, struct epoll_event *events, int maxevents, int timeout) arm,x86,mips # b/34908783 int epoll_create:epoll_create(int size) arm,x86,mips # b/34979910 int creat:creat(const char *pathname, mode_t mode) arm,x86,mips int unlink:unlink(const char *pathname) arm,x86,mips # b/35059702 int lstat64:lstat64(const char*, struct stat64*) arm,x86,mips # b/35217603 int fcntl:fcntl(int fd, int cmd, ... /* arg */ ) arm,x86,mips pid_t fork:fork() arm,x86,mips int poll:poll(struct pollfd *fds, nfds_t nfds, int timeout) arm,x86,mips # b/35906875.
