Subject: [PATCH 4.9 36/47] net: qlogic: Fix memory leak in ql_alloc_large_buffers
Date: Sun, 6 Oct 2019 19:21:23 +0200 [thread overview]
Message-ID: <20191006172018.794229150@linuxfoundation.org> (raw)
In-Reply-To: <20191006172016.873463083@linuxfoundation.org>
From: Navid Emamdoost <navid.emamdoost@gmail.com>
[ Upstream commit 1acb8f2a7a9f10543868ddd737e37424d5c36cf4 ]
In ql_alloc_large_buffers, a new skb is allocated via netdev_alloc_skb.
This skb should be released if pci_dma_mapping_error fails.
Fixes: 0f8ab89e825f ("qla3xxx: Check return code from pci_map_single() in ql_release_to_lrg_buf_free_list(), ql_populate_free_queue(), ql_alloc_large_buffers(), and ql3xxx_send()")
