Subject: [PATCH AUTOSEL for 4.15 12/78] RDMA/iwpm: Fix uninitialized error code in iwpm_send_mapinfo()
Date: Thu, 8 Mar 2018 04:56:06 +0000 [thread overview]
Message-ID: <20180308045525.7662-12-alexander.levin@microsoft.com> (raw)
In-Reply-To: <20180308045525.7662-1-alexander.levin@microsoft.com>
From: Geert Uytterhoeven <geert@linux-m68k.org>
[ Upstream commit 302d6424e4a293a5761997e6c9fc3dfb1e4c355f ]
With gcc-4.1.2:
drivers/infiniband/core/iwpm_util.c: In function ‘iwpm_send_mapinfo’:
drivers/infiniband/core/iwpm_util.c:647: warning: ‘ret’ may be used uninitialized in this function
Indeed, if nl_client is not found in any of the scanned has buckets, ret
will be used uninitialized.
Preinitialize ret to -EINVAL to fix this.
Fixes: 30dc5e63d6a5ad24 ("RDMA/core: Add support for iWARP Port Mapper user space service")
