ubi-tests: fm_param: Replace 'fm_auto' with 'fm_autoconvert'

2019-06-16T10:27:18+00:00

The value of fm_param should be 'fm_autoconvert' rather than 'fm_auto' when fastmap is supported by kernel. Currently, following verbose will appear in dmesg when fm_param is set to 'fm_auto': ubi: unknown parameter 'fm_auto' ignored This patch replace 'fm_auto' with 'fm_autoconvert' for fm_param, so ubi kernel module can receive correct parameters. ---------------------------------------- Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

ubi-tests: mkvol test: Checks return value 'ENOSPC' for 'ubi_mkvol'

2019-06-16T10:27:15+00:00

UBI tests try to create too many volumes in mkvol_bad and mkvol_basic. Currently mtd-utils allows return value 'ENFILE' from 'ubi_mkvol', that works fine in most situations. But what if the number of PEBs equals to the maximum count of volumes? For example, mkvol_basic test will fail in a 64MiB flash with 512KiB PEB size. Following is the output of mkvol_basic test: ====================================================================== ====================================================================== ====================================================================== Test on mtdram, fastmap enabled, VID header offset factor 1 ====================================================================== ====================================================================== ====================================================================== mtdram: 64MiB, PEB size 512KiB, fastmap enabled Running mkvol_basic /dev/ubi0 [mkvol_basic] mkvol_multiple():182: function ubi_mkvol() failed with error 28 (No space left on device) [mkvol_basic] mkvol_multiple():183: vol_id 122 Error: mkvol_basic failed FAILURE The reason is that there is no available PEB to support a new volume. We can see following verbose in dmesg: ubi0: attached mtd0 (name "mtdram test device", size 64 MiB) ubi0: user volume: 0, internal volumes: 1, max. volumes count: 128 ubi0: available PEBs: 122, total reserved PEBs: 6, PEBs reserved for bad PEB handling: 0 The maximum count of volumes is 128, so we can create 128 volumes theoretically. But there are 122 available PEBs becauese of existence of reserved PEBs. In addition, a volume occupies at least one PEB. Actually, we can only create 122 volumes, Therefore, 'ubi_mkvol' returns 'ENOSPC' when mkvol_basic tries to create 123rd volume. And we can see corresponding error message in dmesg: ubi0 error: ubi_create_volume [ubi]: not enough PEBs, only 0 available ubi0 error: ubi_create_volume [ubi]: cannot create volume 122, error -28 So, 'ENOSPC' can happen before 'ENFILE' in flash with a small amount of PEBs. This patch checks return value 'ENOSPC' for 'ubi_mkvol' when mkvol test is trying to create too many volumes. ---------------------------------------- Signed-off-by: Zhihao Cheng Signed-off-by: David Oberhollenzer

ubi-tests: io_read: Filter invalid offset value before 'lseek' in io_read test

2019-06-16T10:27:13+00:00

There are many different offset values passed in 'lseek' during io_read testing of ubi test. The offset value maybe a negative number or a big number that exceeds the volume data size, which can lead to ubi tests failure by passing invalid offset value to 'lseek'. For example: Example 1: The data size of volume is 39525 bytes, offset = (sz) - MAX_NAND_PAGE_SIZE - 1, where MAX_NAND_PAGE_SIZE is 65536. Here, offset is a negative value passed to 'lseek', which leads to fail in io_read. ====================================================================== ====================================================================== ====================================================================== 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 Running mkvol_paral /dev/ubi0 Running rsvol /dev/ubi0 Running io_basic /dev/ubi0 Running io_read /dev/ubi0 [io_basic] test_read3():189: function seek() failed with error 22 (Invalid argument) [io_basic] test_read3():190: len = 1 [io_basic] test_read2():237: offset = -26012 [io_basic] test_read1():303: length = 1 [io_basic] test_read():362: alignment = 7905 Error: io_read failed FAILURE Example 2: The data size of volume is 79035 bytes, offset = 2 * MAX_NAND_PAGE_SIZE, where MAX_NAND_PAGE_SIZE is 65536.

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
