Subject: [PATCH] icmp6 fix no respond to neighbor solicit message |
|
|
|
The structure size used in grub_netbuff_pull to get the pointer to |
|
option header is apparently wrong, which leads to subsequent range check |
|
failed and therefore not responding to any neighbor solicit message in my |
|
testing. |
