Ubuntu 安裝drcom報錯error: ‘struct sk_buff’ has no mem

Ubuntu下用源碼安裝drcom時候，make報錯，9.10和10.04都此問題。

1. /tmp/drcom/drcom.c: In function ‘build_ack_skb’:
2. /tmp/drcom/drcom.c:686: error: ‘struct sk_buff’ has no member named ‘dst’
3. /tmp/drcom/drcom.c: In function ‘build_auth_skb’:
4. /tmp/drcom/drcom.c:723: error: ‘struct sk_buff’ has no member named ‘dst’
5. make[3]: *** [/tmp/drcom/drcom.o] Error 1
6. make[2]: *** [_module_/tmp/drcom] Error 2
7. make[2]: Leaving directory `/usr/src/linux-headers-2.6.32-14-generic’
8. make[1]: *** [default] Error 2
9. make[1]: Leaving directory `/tmp/drcom’
10. Compile drcom kernel module failed!

解決方案： 編輯/kmod/drcom.c 查找__ip_select_ident(iph, skb->dst, 0);
改為 __ip_select_ident(iph, skb_dst(skb), 0); Tip：一共有兩處需要修改，建議額外安裝dkms軟件包，sudo apt-get install dkms，這樣就不用每次更新內核後再手動編譯drcom了
