艰难的安装
最近用铭瑄H610-itx攒了一台nas,想着兼容性高一些专门买了H610的双网卡版本,一张是螃蟹的8125BG,一张是intel的i219V,还以为esxi总不能一个网卡都认不出来吧,然而装好机启动esxi8.0的安装程序一看,又是熟悉的没有网卡的报错一闪而过:
临时找了一个USB网卡凑合了一下,这里需要注意即使插了esxi能识别的usb网卡也依旧会在安装时卡在如下界面:
实际上这时候esxi已经安装完成了,只需要拔掉U盘重启就可以了,只不过重启后仍然无法自动获取ip:
这里只要按F2,登录名输入root 密码空着 直接回车就可以登录(大概是上一遍安装时输入的密码没有写入成功吧)
然后直接在Network Restore Options 里选择 Restore Network Settings,重置网络设置,就可以分配到IP了,然后再在Troubleshooting Options中手动把ssh打开,以便后续操作
驱动的秘密
其实8125BG没有驱动我可以接受,但是i219v之前查VMware官网应该是有支持的,于是lspci看了一下,发现我这张i219v的PCI ID是8086:0DC8,网上搜不到很多相关资料;
0000:00:1f.6 Network controller Ethernet controller: Intel Corporation Ethernet Connection (17) I219-V Class 0200: 8086:0dc8 0000:01:00.0 Network controller Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller Class 0200: 10ec:8125
中间有阵子尝试了一下PVE,发现PVE可以正常识别这两张网卡,所以决定直接去翻linux内核里的驱动代码看看这个0DC8
的device id到底是什么网卡:
没想到果然是主板太新了,居然用的是i219V (22)
而整个linux内核源码对E1000_DEV_ID_PCH_RPL_I219_V22
这个宏的引用也只有这一个地方,看到后面跟的函数和E1000_DEV_ID_PCH_RPL_I219_V17
的函数是一模一样的,说明这两张网卡的驱动实现应该没什么区别。而ESXI是支持I219V (17)的,所以如果能**魔改esxi的intel网卡驱动,把其中关于I219V (17)的ID替换成I219V (22)**的,那么理论上就可以让esxi支持I219V (22)
于是首先在esxi里找了一下intel网卡驱动的存放位置,在/usr/lib/vmware/vmkmod/
目录下的ne1000这个文件:
scp到本地用010 Editor打开,搜索i219v (17) 的device id:1A1D
(由于字节序问题要反过来搜索1D1A)
可以看到驱动中确实有I219V (17)的PCI ID信息,理论上只要把这里改成C8 0D
(I219V (22) 的ID)就可以让驱动误以为网卡是I219V (17),然后正常加载
然而当我想尝试修改这个文件的时候却发现这个文件夹内的文件根本没法编辑,即便是简单改一下文件名也会有如下报错:
于是我又将修改后的驱动文件改名为ne1001,然后上传到了这个文件夹,想着如果ESXI内核会遍历这个文件夹下的模块来加载驱动,应该可以一并加载上。但是重启之后却发现之前上传的文件直接消失了!
这时我觉得这个这个目录应该不是一个真正位于磁盘上的目录,而只是内核虚拟出来的,真正的驱动文件应该另有存放位置,所以我直接在根目录下搜索了一下文件名包含ne1000的文件:
注意到还有很多相关的文件,而最后这个文件:/vmfs/volumes/ea311779-c343e9f0-fdb8-e70146ecc34b/ne1000.v00
看起来更像是位于磁盘上的真实文件,所以就搜索了一下v00这个拓展名,找到了这么两个介绍:
https://www.v-front.de/2011/08/anatomy-of-esxi-50-installation-cd-and.html
https://polarclouds.co.uk/esxi7-missing-percs/
原来这些是以gz格式压缩后的设备驱动文件,并且esxi有一个专门的vmtar
命令用来在tar和这种文件中间进行转换:vmtar -x ne1000.v00 -o ne1000.tar
就可以将上面的v00文件转换为tar文件
(这里为了便于查看将7z的显示模式调成了平铺模式,实际的目录类似于deb包,是可以在根目录下直接解压安装的)
开始魔改
可以看到这个文件中除了包含我们之前想修改的ne1000文件,还包含了两个用于描述驱动信息的文件,打开发现这两个文件中也包含着PCI ID的相关信息,所以也要一并改掉,修改完之后的三个文件效果如下:
ne1000:
ne1000.ids:
ne1000.map:
修改完之后上传回之前的目录,再用这三条命令重新打包回v00,覆盖原有的文件:vmtar -c ne1000.tar -o ne1000.vgz
gzip ne1000.vgz
mv ne1000.vgz.gz ne1000.v00
ESXI 启动!
这下重启应该就大功告成了吧?没想到居然还是没认出来网卡!
于是我grep了一下vmkernel log:cat /var/log/vmkernel.log |grep ne1000
发现了如下报错:

看起来已经很接近成功了,因为esxi内核已经尝试去加载这个驱动了,只是驱动内部可能还有代码逻辑来检测网卡id,导致识别失败。
这时就不得不请出IDA Pro了,直接把ne1000这个文件拖进去反编译:
IDA 启动!
根据上面的报错代码failed to identify hw with shared code
直接在在字符串中搜索:
交叉引用找到打印报错的函数:

而ne1000_bridgeIdentify
函数又会依次调用e1000_set_mac_type
、e1000_setup_init_funcs
和e1000_get_bus_info
,而后两个函数的日志似乎没有打印,可见应该是第一个e1000_set_mac_type
函数就出现了错误

这个函数中充满了大量的switch-case,可见确实是在对网卡ID进行判断,我们找到原本I219V-19应该进入的分支:
发现只要将上面的0xD4C改为比0xDC8更大的数就可以正常的网卡进入LABLE_18后面的代码
在使用IDA patch这一处代码之后重新制作v00文件并上传覆盖,重启之后ESXI终于认出了网卡:
后记
在b站上看到有UP主教多久如何更改网卡的eeprom来修改网卡的PCI ID,但是评论区有很多人表示容易把网卡刷坏,那么我这里就提供一种纯软件的解决方法。
感谢你看到这里,如果你并不想像我这样折腾也可以直接下载我patch好的v00文件,只要覆盖掉原本的ne1000.v00后重启即可:
