Date: Sun, 11 Aug 2019 15:07:47 -0500 From: Wenwen Wang <wenwen@...uga.edu> To: Wenwen Wang <wenwen@...uga.edu> Cc: Jeff Kirsher <jeffrey.t.kirsher@...el.com>, "David S. Miller" <davem@...emloft.net>, intel-wired-lan@...ts.osuosl.org (moderated list:INTEL ETHERNET DRIVERS), netdev@...r.kernel.org (open list:NETWORKING DRIVERS), linux-kernel@...r.kernel.org (open list) Subject: [PATCH] net: ixgbe: fix memory leaks In ixgbe_configure_clsu32(), 'jump', 'input', and 'mask' are allocated through kzalloc() respectively in a for loop body. Then, ixgbe_clsu32_build_input() is invoked to build the input. If this process fails, next iteration of the for loop will be executed. However, the allocated 'jump', 'input', and 'mask' are not deallocated on this execution path, leading to memory leaks.
