函数名称：moyo_write_unix_network - Write "struct tomoyo_unix_acl" list.*@param: Pointer to "struct tomoyo_acl_param".* Returns 0 on success, negative value otherwise.

函数原型：int tomoyo_write_unix_network(struct tomoyo_acl_param *param)

返回类型：int

参数：

类型参数名称
struct tomoyo_acl_param *param
329  struct tomoyo_unix_acl e = { One of values in "enum tomoyo_acl_entry_type_index". = TOMOYO_TYPE_UNIX_ACL}
332  protocol等于tomoyo_read_token(param)
333  operation等于tomoyo_read_token(param)
335  以protocol小于TOMOYO checks only SOCK_STREAM, SOCK_DGRAM, SOCK_RAW, SOCK_SEQPACKET.* Therefore, we don't need SOCK_MAX.循环如果非字符串比较则
337  退出
338  以type小于TOMOYO_MAX_NETWORK_OPERATION循环如果tomoyo_permstr(operation, String table for socket's operation. [type])则
340  Bitmask of values in "enum tomoyo_network_acl_index" 或等于1左移type位
341  如果protocol恒等于TOMOYO checks only SOCK_STREAM, SOCK_DGRAM, SOCK_RAW, SOCK_SEQPACKET.* Therefore, we don't need SOCK_MAX.或非Bitmask of values in "enum tomoyo_network_acl_index" 则返回:负EINVAL
343  如果非moyo_parse_name_union - Parse a tomoyo_name_union.*@param: Pointer to "struct tomoyo_acl_param".*@ptr: Pointer to "struct tomoyo_name_union".* Returns true on success, false otherwise.则返回:负EINVAL
345  error等于moyo_update_domain - Update an entry for domain policy.*@new_entry: Pointer to "struct tomoyo_acl_info".*@size: Size of @new_entry in bytes.*@param: Pointer to "struct tomoyo_acl_param".*@check_duplicate: Callback function to find duplicated entry.
348  moyo_put_name_union - Drop reference on "struct tomoyo_name_union".*@ptr: Pointer to "struct tomoyo_name_union".* Returns nothing.
349  返回:error
