手机移动端网卡信息获取原理分析

发布于：2024-04-17 ⋅ 阅读:(31) ⋅ 点赞:(0)

有些场景我们需要获取当前手机上的网卡信息（如双卡双待、Wifi等）。本文准备研究一下这块的原理，以便更好的掌握相关技术原理。

1、底层系统接口 getifaddrs
使用 getifaddrs 接口可以达到我们的目的，该接口会返回本地所有网卡的信息，结果保存在 ifaddrs 结构的链表中，但结果中可能存在不是蜂窝网络的结果，因此需要进一步做筛选过滤。详细介绍可以查阅官方文档：https://man7.org/linux/man-pages/man3/getifaddrs.3.html。

2、存在的问题-虚拟网卡
虚拟网卡是什么， 指名称（ifa_name）中包含 vmnet、vnic 的网卡；

3、关于网卡的常识
3.1 网卡名称，对应 ifaddrs 中的 ifa_name 成员，

ifa_name 用途
awdl0 在iOS中，ifa_name 值为 awdl0 的网络接口代表的是“Apple Wireless Direct Link”（AWDL）。AWDL是苹果开发的一种专用于设备间直接通信的网络协议，利用该协议，苹果设备能够进行点对点的连接，从而支持AirDrop、AirPlay、游戏连接和其他形式的设备间通信。
enX 在 iOS 中，ifa_name 为 en0、en1、en2 等表示的是 Ethernet 接口，通常用于连接到本地网络或者互联网。这些接口代表设备上的不同网络接口，例如 Wi-Fi、以太网（Ethernet）、蓝牙网络等。
pdp_ipX 在iOS设备中，ifa_name 值为 pdp_ip0, pdp_ip1, pdp_ip2, pdp_ip5 等都代表蜂窝数据网络接口。这些接口用于管理设备通过蜂窝网络（例如3G、4G LTE或5G）进行的数据通信。每个 pdp_ipX 接口代表一个蜂窝数据通道，这些通道可以用于不同的数据服务或应用。
utunX 在 iOS 中，ifa_name 为 utun0、utun1、utun2、utun3 等表示的是 UTUN 接口，是一种虚拟网络接口，通常用于建立 VPN（Virtual Private Network，虚拟专用网络）连接。每个 utunX 接口代表一个不同的 VPN 连接，其中 X 是一个数字标识符，用于区分不同的接口。这些接口可以用于实现安全的通信，例如连接到公司内部网络或者使用特定的安全服务。
ipsecX 在 iOS 中，ifa_name 为 ipsec0、ipsec1、ipsec2 等表示的是 IPsec（Internet Protocol Security，互联网协议安全）接口。IPsec 是一种用于保护 IP 数据包的协议，通常用于建立安全的通信连接，例如 VPN（Virtual Private Network，虚拟专用网络）连接。这些接口通常用于实现 IPsec VPN 连接，以提供加密和认证功能，确保通信的安全性和完整性。
anpi0 当ifa_name为anpi0时，代表使用了自定义的网络插件接口（Apple Network Plug-in Interface）。这种接口的应用场景可能是通过自定义的网络插件实现特定的网络功能或协议。例如，某些企业可能需要定制化的网络连接方式，以满足其特定的安全要求或者与特定的网络设备进行通信。
llw0 在 iOS 中，ifa_name 为 llw0 的接口通常与需要低延迟通信（ Low Latency Wireless)的应用相关联。一个实际的应用例子是实时音频或视频通话应用，比如视频会议软件或者语音通话应用。这些应用需要保持低延迟的数据传输，以确保用户之间的通信流畅、自然，而不会出现明显的延迟或者延迟。

3.2 检测网卡是否运行

怎样算是运行？域 IFF_UP 的区别是什么？
(IFF_RUNNING & interface->ifa_flags) // 这里 interface 是 ifaddrs 结构的变量

3.2 检测网卡是否是本地回环地址
怎样算是回环地址？

(IFF_LOOPBACK & interface->ifa_flags)

3.2 检测网卡是否已被分配 ip 地址

(nullptr == interface->ifa_addr)

struct ifaddrs {
	struct ifaddrs	*ifa_next;              /* Next item in list */
	char		*ifa_name;              /* Name of interface */
	unsigned int	ifa_flags;              /* Flags from SIOCGIFFLAGS */
	struct sockaddr *ifa_addr;              /* Address of interface */
	struct sockaddr *ifa_netmask;           /* Netmask of interface */
	union {
		struct sockaddr *ifu_broadaddr;
		/* Broadcast address of interface */
		struct sockaddr *ifu_dstaddr;
		/* Point-to-point destination address */
	} ifa_ifu;
#define              ifa_broadaddr	ifa_ifu.ifu_broadaddr
#define              ifa_dstaddr	ifa_ifu.ifu_dstaddr
	void *ifa_data;                      /* Address-specific data */
};

4、真机测试结果
分别有以下五种情况：1、wifi 功能关闭，移动未插卡且关闭
；2、wifi 功能开启但未连接任何网络，移动未插卡且关闭；3、wifi 功能开启且连接网络，移动未插卡且关闭；4、wifi 功能开启且连接网络，移动单槽插卡且关闭；5、wifi 功能开启且连接网络，移动单槽插卡且开启；6、wifi 功能开启且连接网络，移动双槽槽插卡且开启，不允许切换蜂窝数据；7、wifi 功能开启且连接网络，移动双槽插卡且开启，允许切换蜂窝数据；

6、在哪里新增双链路代码，为什么在该处
在连接建立阶段（创建 socket 时，调用 connect 前），因为 Wifi或者蜂窝必须是二选一，Wifi 弱时不要再做无谓建连尝试了，避免增加网络成本，而是直接使用蜂窝网络即可。

iOS：
interface_index 为蜂窝网络的索引值，socket_fd_ 则为新建的 socket。

setsockopt(socket_fd_, IPPROTO_IP /* IPPROTO_IPV6 */, IP_BOUND_IF,
           &interface_index, sizeof(interface_index));

安卓端：
需要区分 M 还是 L，前者需要用 android_setsocknetwork，后者则使用 setNetworkForSocket。

using LollipopSetNetworkForSocket = int (*)(unsigned net_id, int socket_fd);
using MarshmallowSetNetworkForSocket = int (*)(int64_t net_id, int socket_fd);

MarshmallowSetNetworkForSocket GetMarshmallowSetNetworkForSocket() {
  // On Android M and newer releases use supported NDK API.
  base::FilePath file(base::GetNativeLibraryName("android"));
  // See declaration of android_setsocknetwork() here:
  // http://androidxref.com/6.0.0_r1/xref/development/ndk/platforms/android-M/include/android/multinetwork.h#65
  // Function cannot be called directly as it will cause app to fail to load on
  // pre-marshmallow devices.
  void* dl = dlopen(file.value().c_str(), RTLD_NOW);
  return reinterpret_cast<MarshmallowSetNetworkForSocket>(
      dlsym(dl, "android_setsocknetwork"));
}

LollipopSetNetworkForSocket GetLollipopSetNetworkForSocket() {
  // On Android L use setNetworkForSocket from libnetd_client.so. Android's netd
  // client library should always be loaded in our address space as it shims
  // socket().
  base::FilePath file(base::GetNativeLibraryName("netd_client"));
  // Use RTLD_NOW to match Android's prior loading of the library:
  // http://androidxref.com/6.0.0_r5/xref/bionic/libc/bionic/NetdClient.cpp#37
  // Use RTLD_NOLOAD to assert that the library is already loaded and avoid
  // doing any disk IO.
  void* dl = dlopen(file.value().c_str(), RTLD_NOW | RTLD_NOLOAD);
  return reinterpret_cast<LollipopSetNetworkForSocket>(
      dlsym(dl, "setNetworkForSocket"));
}
