Subject: [dpdk-dev] [PATCH v3] drivers: ifpga_rawdev: fix fd leak in rte_fpga_do_pr
Date: Tue, 16 Apr 2019 13:05:14 +0800 [thread overview]
Message-ID: <20190416050514.2784-1-liq3ea@163.com> (raw)
Message-ID: <20190416050514.VI7OjLH9mgVgPIfrEJM7ODHwmE26FN0tcKA9hV-uoHo@z> (raw)
In rte_fpga_do_pr() function, if 'stat' return error the
'file_fd' is never closed thus leading a fd leak. This patch
avoids this.
Coverity issue: 279441
Fixes: ef1e8ede3da59e("raw/ifpga: add Intel FPGA bus rawdev driver")
