ubi-tests: ubi_mkvol_request: Fully initialize 'struct ubi_mkvol_request req'

2019-06-16T10:27:10+00:00

'struct ubi_mkvol_request req' is one parameter of the function 'ubi_mkvol' , this parameter will be passed to kernel and then be checked. It acts as a local variable in many ubi tests, such as io_basic, io_read, mkvol_bad, mkvol_basic, etc. After commit c355aa465fce ("ubi: expose the volume CRC check skip flag") in linux-stable, 'struct ubi_mkvol_request' supports a new configuration named 'flags', and req.flags will be checked in kernel function 'verify_mkvol_req'. Currently, there is no initialization for req.flags before 'ubi_mkvol' invoked. So, req.flags can be an arbitrary number passed to kernel. When we run ubi tests in qemu (x86_64, kernel image: 5.2.0-rc4), the following errors may occur: ====================================================================== ====================================================================== ====================================================================== Test on mtdram, fastmap enabled, VID header offset factor 1 ====================================================================== ====================================================================== ====================================================================== mtdram: 16MiB, PEB size 16KiB, fastmap enabled Running mkvol_basic /dev/ubi0 Running mkvol_bad /dev/ubi0 [mkvol_bad] test_mkvol():105: ubi_mkvol failed with error 22 (Invalid argument), expected 28 (No space left on device) [mkvol_bad] test_mkvol():105: bytes = 16060929 Error: mkvol_bad failed FAILURE This patch fully initializes every 'struct ubi_mkvol_request req' passed to 'ubi_mkvol', which can fix the bug that the ubi test failed caused by that req.flags was not initialized. And it is still compatible with old kernel before kernel commit c355aa465fce ("ubi: expose the volume CRC check skip flag"). ---------------------------------------- Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer
