When neighbour table is full, dst_neigh_lookup/dst_neigh_lookup_skb will return -ENOBUFS which is absolutely non zero, while all the code in kernel which use above functions assume failure only on zero return which will cause panic. (for example: : https://bugzilla.kernel.org/show_bug.cgi?id=54731). This patch corrects above error with smallest changes to kernel source code and also correct two return value check missing bugs in drivers/infiniband/hw/cxgb4/cm.c Tested on my x86_64 SMP machine Reported-by: Zhouyi Zhou <zhouzhouyi@gmail.com> Tested-by: Zhouyi Zhou <zhouzhouyi@gmail.com> Signed-off-by: Zhouyi Zhou <zhouzhouyi@gmail.com> Signed-off-by: David S.
