Hi Shan Wei or David, ce46cc64d47a8afaf13c300b09a7f9c29f4979b6 net: neighbour: prohibit negative value for unres_qlen_bytes parameter This looks applicable to stable-3.4, I can reproduce it on this 3.4 kernel. It fixes a type overflow when setting unres_qlen. I try to reproduce, and then this patch works well. But git am or patch -p1 failed, because a previous patch [commit 9a6308d74ed (neighbour: Stop using NLA_PUT*().)] change the NLA_PUT_U32 to nla_put_u32. With some modifies, it was built successful for me. What do you think? stable-3.0 and stable-3.2 are free from this bug. And the bug was fixed in 3.8; The commit got its way into mainline in 3.8 cycle. Thanks!
