如何修复不基于CENTOS的802.11 Linux驱动程序？

Question

我已经安装了CENTOS 6.3。我的机器是戴尔工作室。我有下面的无线broadcom模型。

[root@treasure hybrid_wl]# lspci | grep -i wireless
03:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

我从sta.php获得了这个驱动程序的源代码。

我的机器内核是

[root@treasure hybrid_wl]# uname -r
2.6.32-358.18.1.el6.x86_64

在从sta.php构建包时。我得到以下错误。

KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`

我怎么才能解决这个问题？我遗漏了什么？我已经更新了Broadcom支持组的电子邮件id，这里是linux-wlan-client- support -list@broadcom.com。Broadcom是一家领先的公司，我希望他们能在这里提供帮助。我也给他们发了邮件。Broadcom只能在这里分享他们的解决方案，这样世界就可以从中受益。

对于Broadcom，我已经在堆栈溢出上发布了这条消息，因为每个人都可以从中获得优势。目前，我无法在笔记本电脑上使用WIFI。我被有线连接卡住了。请帮帮我，这样我才能让WIFI正常工作。当什么都没有建立的时候，我尝试了下面的最新版本。

make API=WEXT (弃用)

这可以检测到可用的wifi网络，但是它无法连接到AP。看起来这需要无线扩展工具。

我需要为它安装任何东西。还是说，不要使用不推荐的构建规则，而是修复构建错误？你对此有什么建议？

建议，我可以跟进。

关键是: /home/joshis1/hybrid_wl/src/wl/sys/wl_cfg80211_hybrid.c:2122:错误:函数‘cfg80211_roamed’的参数太少

如果您检查wl_cfg80211_hybrid.c ~第2122行

cfg80211_roamed(ndev,
#if LINUX_VERSION_CODE > KERNEL_VERSION(2, 6, 39)
                    NULL,
#endif
    (u8 *)&wl->bssid,  conn_info->req_ie, conn_info->req_ie_len,
    conn_info->resp_ie, conn_info->resp_ie_len,        GFP_KERNEL);
    WL_DBG(("roaming result\n"));
}

虽然我使用2.6.32运行that 6.5，但它运行的是net/cfg80211.h版本，它需要额外的参数，所以我需要将行改为：#if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 32) --或者完全删除if/endif。不幸的是，它并没有就此结束，如果是在需要更改的KERNEL_VERSION中，则大约有十几个wl_cfg80211_hybrid.c。

一旦完成(您可以测试，但运行'make‘，并返回和修复错误)，它确实编译和安装良好。我现在用WPA运行它，等等。如预期的那样。似乎仅仅是RedHat将一些cfg80211从最近的内核引入到2.6.32中，这使模块感到困惑。

上周，我朋友的CentOS 6.4宏碁笔记本电脑(BCM 43227 WiFi)也出现了同样的问题。Broadcom驱动程序只能使用API=WEXT选项构建(否则，与您引用的错误消息相同)，但是它只在“开放”WiFi网络中工作，而不是WPA/WPA 2(不知道WEP)。在/var/log/ WPA _supplicant.log中，当试图连接到WPA网络时，我得到了错误消息association request to the driver failed，而NetworkManager只会继续询问密码。

除了直接编译Broadcom驱动程序之外，我还尝试按照ELRepo wl kmod (通过CentOS维基)的建议构建RPM包，但也失败了( Broadcom文件名与RPM预期的不同)。

这个周末，我再次看了看电脑，发现ELRepo中链接的RPM文件已经改变了，文档本身也在9月26日更新。因此，我再次尝试使用更新的RPM，完全遵循使用说明，这一次它起作用了。得到一个安装了wl.ko内核模块的RPM文件。通过modprobe wl加载它，在此之后，NetworkManager找到了我的WPA2 wifi，并在第一次尝试中连接。
