Re: rnfs: rq_respages pointer is bad

[PATCH v2] IB/ipoib: fix dangling pointer references to ipoib_neigh and ipoib_path

2010-03-01 Thread Ralph Campbell
When using connected mode, ipoib_cm_create_tx() kmallocs a struct ipoib_cm_tx which contains pointers to ipoib_neigh and ipoib_path. If the paths are flushed or the struct neighbour is destroyed, the pointers held by struct ipoib_cm_tx can reference freed memory. Signed-off-by: Ralph Campbell ---
