'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").

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.

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.

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'

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.
