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

ubi-tests: io_paral: Fix error handling of update_volume()

2018-09-08T16:48:46+00:00

The io_paral test returns success even in case it throws e.g. the following error message: [io_paral] update_volume():125: written and read data are different This patch fixes so that the io_paral application returns a non-zero error code when an error is detected.

ubi: tests: Speedup io_paral by using rand_r()

2017-02-21T09:13:26+00:00

rand() is not thread safe, but glibc seems to use a shared state which is protected by a mutex. io_paral spawns a few threads and they call rand() more or less in parallel, which causes heavy lock contention. That makes the test extremely slow on some setups. Signed-off-by: Richard Weinberger Signed-off-by: David Gstir Signed-off-by: David Oberhollenzer

ubi-tests: rename common.[ch] to helpers.[ch]

UBI: sync ubi-user.h with kernel v3.6-rc1

2012-08-22T10:20:49+00:00

Also remove the eraseblock type support, because kernel commit a65a0eb6d198e058687a9214683bd1c418f20d39 set the dtype parameter as obsolete. Also adjust to some renames: * 'UBI_PROP_DIRECT_WRITE' -> 'UBI_VOL_PROP_DIRECT_WRITE' * 'struct ubi_set_prop_req' -> 'struct ubi_set_vol_prop_req'. * 'UBI_IOCSETPROP' -> 'UBI_IOCSETVOLPROP' Signed-off-by: Richard Genoud Signed-off-by: Artem Bityutskiy

mtd-tests: io_paral: build error, "variable length strings"

2011-06-29T05:42:38+00:00

Some compilers will complain about use of strlen() within a static array size declaration. For this type of string, "sizeof() - 1" is equivalent and prevents the build error.
