2.13.6
Inject memory/io fault while repairing corrupted UBIFS images.
This testcase mainly checks whether ubifs_repair has problems (eg.
memleak, UAF, null-ptr-def, etc.) in random error paths. Besides,
it provides a similar way to simulate powercut during repairing,
and checks whether ubifs_repair can fix an UBIFS image after many
repairing rounds interrupted by kinds of errors.

Inject powercut while doing fsstress on mounted UBIFS, check the
consistency of UBIFS after repairing.
This testscase mainly makes sure that ubifs_repair can make UBIFS
image be consistent in common stress cases and powercut cases.

2.13.6
Inject random corruption on UBIFS image by writting random data on
kinds of mtd devices (eg. nand, nor), check the consistency of UBIFS
after repairing.
This testcase simulate random bad UBIFS image caused by hardware
exceptions(eg. ecc uncorrectable, unwritten), and makes sure that
ubifs_repair could make UBIFS be consistent after repairing UBIFS
image.

2.13.6
Inject powercut while doing fsstress on mounted UBIFS for kinds of
flashes (eg. nand, nor).
This testcase mainly makes sure that ubifs_repair can make UBIFS image
be consistent on different flashes (eg. nand, nor). Because the
min_io_size of nor flash is 1, the UBIFS image on nor flash will be
different from nand flash after doing powercut, so we need make sure
ubifs_repair can handle these two types of flash.

This is a preparation for adding repairing testcase. There is no debugfs
tools (for example: debugfs[ext4], xfs_db) for UBIFS, so no way to inject
precise corruption into UBIFS image, we have to prepare inconsistent
UBIFS images in advance like e2fsprogs[1] does. (Goto [2] to see how to
generate inconsistent UBIFS images). Here's a descriptons of the various
test images:

+ ubifs_repair tests
+ ==================
+
+ There are seven testcases for ubifs_repair on encryption/non-encryption
+ situations:
+ 1) authentication_refuse: Currently authenticated UBIFS image is not
+ supported for repairing, check whether ubifs_repair can refuse
+ authenticated UBIFS image.
+ 2) random_corrupted_repair: Inject random corruption on UBIFS image
+ by writting random data on kinds of mtd devices (eg. nand, nor),
+ check the consistency of UBIFS after repairing.
+ This testcase simulate random bad UBIFS image caused by hardware
+ exceptions(eg. ecc uncorrectable, unwritten), and makes sure that
+ ubifs_repair could make UBIFS be consistent after repairing UBIFS
+ image.
+ 3) cycle_corrupted_repair_fault_inject: Inject memory/io fault while
+ repairing corrupted UBIFS images.
+ This testcase mainly checks whether ubifs_repair has problems (eg.
+ memleak, UAF, null-ptr-def, etc.) in random error paths. Besides,
+ it provides a similar way to simulate powercut during repairing,
+ and checks whether ubifs_repair can fix an UBIFS image after many
+ repairing rounds interrupted by kinds of errors.
+ 4) cycle_powercut_mount_repair: Inject powercut while doing fsstress
+ on mounted UBIFS, check the consistency of UBIFS after repairing.
+ This testscase mainly makes sure that ubifs_repair can make UBIFS
+ image be consistent in common stress cases and powercut cases.
+ 5) powercut_repair_mount: Inject powercut while doing fsstress on
+ mounted UBIFS for kinds of flashes (eg. nand, nor).
+ This testcase mainly makes sure that ubifs_repair can make UBIFS
+ image be consistent on different flashes (eg. nand, nor). Because
+ the min_io_size of nor flash is 1, the UBIFS image on nor flash
+ will be different from nand flash after doing powercut, so we need
+ make sure ubifs_repair can handle these two types of flash.
+ 6) cycle_mount_repair_check: Do fsstress and repair ubifs image, make
+ sure all files(and their data) are not lost after repairing.
+ This testcase mainly checks whether ubifs_repair could corrupt
+ filesystem content in common case.
+ 7) repair_bad_image: For kinds of inconsistent UBIFS images(which
+ can simulate corruptions caused by some potentional UBIFS bug), check
+ repairing result.
+ This testcase mainly checks whether the behavior is in expected after
+ repairing specific inconsistent UBIFS image. There is no debugfs tools
+ (for example: debugfs[ext4], xfs_db) for UBIFS, so no way to inject
+ precise corruption into UBIFS image, we have to prepare inconsistent
+ UBIFS images in advance like e2fsprogs[1] does. (Goto [2] to see how to
+ generate inconsistent UBIFS images). Here's a descriptons of the various
+ test images:
