[PATCH 3.18 106/154] IB/mlx4: Fix memory leak in __mlx4_ib_modify_qp

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Majd Dibbiny <majd@xxxxxxxxxxxx>

commit bede98e781747623ae170667694a71ef19c6ba7f upstream.

In case handle_eth_ud_smac_index fails, we need to free the allocated resources.

Fixes: 2f5bb473681b ("mlx4: Add ref counting to port MAC table for RoCE")
