2019-11-10mkfs.ubifs: don't leak copied command line argumentsDavid Oberhollenzer
For some command line flags, the argument string is copied. Simply writing over the buffer leads to a resource leak if the same flag is specified on the command line more than once. This patch adds a free() call to the old buffer before overwriting it with the new copy. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-11-10mkfs.ubifs: abort add_directory if readdir failsDavid Oberhollenzer
The existing code sets 'err' to -1 and breaks the readdir loop, but the error state is never read. This patch modifies the readdir loop to actualy jump to the error handling branch if readdir fails. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-11-10mkfs.ubifs: fscrypt: bail from encrypt_block if gen_essiv_salt failsDavid Oberhollenzer
What originally cought my attention was that gen_essiv_salt has a size_t return type and error paths that return -1 on failure. Further investigation revealed that the error value is never checked for. The encrypt_block function doesn't use the return value in any way and simply continues onward. Furthermore, the gen_essiv_salt function has an error case that emits an error message but returns success state. This patch modifes gen_essiv_salt to return an error status in all error branches, changes the return type to ssize_t and adds a check to encrypt_block if gen_essiv_salt fails.

ubihealthd is a simple daemon which scans every PEB of an UBI device in random order. It helps to deal with read disturb on systems which either reboot seldom, use fastmap or read few data. To use this daemon you need Linux >= v5.1. Signed-off-by: Richard Weinberger <richard@nod.at>
2019-08-19mkfs.ubifs: Add authentication supportSascha Hauer
This adds support for authenticated UBIFS images. In authenticated images all UBIFS nodes are hashed as described in the UBIFS authentication whitepaper. Additionally the superblock node contains a hash of the master node and itself is cryptographically signed in a node following the superblock node. The signature is in PKCS #7 CMS format. To generate an authenticated image these options are necessary: --hash-algo=NAME hash algorithm to use for signed images (Valid options include sha1, sha256, sha512) --auth-key=FILE filename or PKCS #11 uri containing the authentication key for signing --auth-cert=FILE Authentication certificate filename for signing.

2019-07-09mkfs.ubifs: remove ZSTD_CLEVEL_DEFAULT for backwards compatibillityDavid Oberhollenzer
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. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-06-16ubi-tests: mkvol test: Checks return value 'ENOSPC' for 'ubi_mkvol'Zhihao Cheng
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 <chengzhihao1@huawei.com> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-06-16ubi-tests: io_read: Filter invalid offset value before 'lseek' in io_read testZhihao Cheng
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.

2019-06-16ubi-tests: ubi_mkvol_request: Fully initialize 'struct ubi_mkvol_request req'Zhihao Cheng
'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 <chengzhihao1@huawei.com> Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

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.

2019-04-03mkfs.ubifs: fix regression when trying to store device special filesDavid Oberhollenzer
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.
