big. The current wording got this wrong.

Support for ZSTD compression has been added recently through the ZSTD
library, which is famously known for its incredibly well designed and
stable API.
This patch removes usage of ZSTD_CLEVEL_DEFAULT, which isn't exposed
in older versions of the ZSTD library, and replaces it with with the
constant parameter 0. According to the documentation this should then
use a reasonable default (which is defined internally).
Other possible approachs include defining ZSTD_CLEVEL_DEFAULT to 3
(the value it _currently_ has) if it isn't defined. This patch chooses
the approach of passing 0 since this seems to be encouraged by the
existing documentation.

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.

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.

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.

'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

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 UBIFS image was created via
mkfs.ubifs -x $Comp -m 512 -e 128KiB -c 2200 -r $image $out
I used "debootstrap sid" to create a basic RFS and the results are in
the `image' column. The image2 column denotes the results for the same
image but with .deb files removed.
The time column contains the output of the run time of the command.
ZSTD's compression level three is currently default. Based on the
compression results (for the default level) it outperforms LZO in
run time and compression and is almost as good as ZLIB in terms of
compression but quicker.
The higher compression levels make almost no difference in compression
but take a lot of time.
The compression level used is the default offered by ZSTD. It does not
make sense the higher levels.

The function insert_biterror should be designed to insert error at
the first '1' bit starting at offset byte.
But now, only bit 7 of each byte is checked, because checking mask
is always 0x80.
So, do right shift for checking mask after each checking to check
the whole 8 bits of each bytes.

Commit a767dd30 added a check to add_inode that bails when trying to
store extra data in anything other than a symlink. The symlink
encryption support added by that commit relies on the assumption.
Unfortionately it was overlooked that device special files also store
the device number as additional data in the inode. The check added in
commit a767dd30 broke support for device files in mkfs.ubifs.
This commit adds a quick and dirty fix, moving the check into the
fscrypt branch, breaking only the fscrypt version but restoring old
functionality for unencrypted file systems.

In inode_add_xattr(), it malloc a buffer for name, and then passes
the bufffer ptr to add_xattr(). The ptr will be used to create a new
idx_entry in add_to_index().
However, inode_add_xattr() will free the buffer before return.
which can cause double free in write_index(): free(idx_ptr[i]->name)

When we create a ubi image by ubinize, a UBI_LAYOUT_VOLUME_ID
volume will be created by ubigen_write_layout_vol().
However, after the commit 4c00cf2c5816 (ubiformat: remove
no-volume-table option), ubiformat remove novtbl args in format().
As a result, it will also create a layout volume.
When we attempt to do ubiattach, it will fail for ubi_compare_lebs error:
