Subject: [PATCH AUTOSEL 4.14 07/33] scsi: lpfc: Fix crash when lpfc_sli4_hba_setup() fails to initialize the SGLs
Date: Fri, 9 Jul 2021 22:34:49 -0400 [thread overview]
Message-ID: <20210710023516.3172075-7-sashal@kernel.org> (raw)
In-Reply-To: <20210710023516.3172075-1-sashal@kernel.org>
From: James Smart <jsmart2021@gmail.com>
[ Upstream commit 5aa615d195f1e142c662cb2253f057c9baec7531 ]
The driver is encountering a crash in lpfc_free_iocb_list() while
performing initial attachment.
Code review found this to be an errant failure path that was taken, jumping
to a tag that then referenced structures that were uninitialized.
Fix the failure path.
