In the problem above I've spend several hours waiting for the issue to
appear, only to had the 'luck' that it was found in a file whose name was
256 bytes in length, resulting in the write to fail. Closer examination
showed that the buffer to store the path was 256 bytes in length, but this
buffer also includes /tmp and the read/write suffix and should be able to
contain a filename which is up to 255 bytes (NAME_MAX in linux/limits.h)
in size which is a bad fit. So that array is modified to FILENAME_MAX
(stdio_lim.h) and some checking is added to truncate the filename should
it cause an overflow.
The following log shows the first patch in action (see the correct seed),
and shows why this third patch is needed:

the errors
See my problem description int the previous commit, the point is that integck
in file_check_data reads a buffer, and then checks if the data is correct, it
will do a seek(0), and reread from the same fd. The point is that in the
scenario I observed integck failed (due to a buffer mismatch) but the it saved
(and what was in flash) was actually correct. So I modified this function to
dump the buffers to stderr at the moment an error is found.

And I would expect the file data listing to include at offset 826 something
with a size of 357 and a seed of 5908448. Clearly it is not there (which
is already extremely confusing). The point is that file_write_info first
updates the raw_write, then verifies the data (passing the new write)
and only after that updates the write structure. But in file_check_data
only the newly written data is verified (passed as an argument) whilst
the save_file() function to dump the file uses the raw_writes to recreate
the written data (while raw_writes is only updated after after this check
would have succeeded). Several lines to say that in this patch the verify
only gets called _after_ the datastructures are updated.

When doing something like:
{ printf "\xff"; printf "\xfe"; } | flash_otp_write -u /dev/mtd0 0
flash_otp_write might see only a single byte when reading from stdin for
the first tim. In this case (and without this patch) it pads to
$writesize with '\xff's and writes that out. In the next iteration it
reads the 2nd byte, pads and writes again. So the 2nd byte is written to
offset $writesize instead of 1.

Technically, '-l' linker options should be included only after the
objects which must link to the library. So when we include '-lpthread'
in the LDFLAGS variable, it gets placed too early (i.e., before the
io_paral.o object), and so the pthread linkage never occurs. The
following error probably only shows up with linkers that don't link
pthreads by default.

The is_contained() function returns -1 if an error occurs when
canonicalizing the output file path/root directory. This resulted in the
confusing error message 'Error: The output file cannot be in the UBIFS
root' when specifying a non-existent directory for the output.
This patch changes the error handling to display a different error
message for the case when is_contained() returns -1.
Additionally it frees all memory allocated by is_contained().

We use the 'in_path()' function to check whether the output image is
withing the mkfs.ubifs root directory or not. However, this function
is not correct and it fails for the following situation, as
Marcus Prebble <marcus.prebble@axis.com> reports:
1. We have our root file-system mounted at / and want to build an image
out of it.
2. We have tmpfs mounted at /tmp
3. We mount the root file-system under /tmp/newroot
4. We run mkfs.ubifs with -r /tmp/newroot -o /tmp/image
And this fails. It fails because 'in_path()' misses this use-case.
This patch re-implements the check completely. Now we use 'realpath()'
to find canonical paths and just check that the output file is not
under the root mkfs.ubifs directory.

The offset (which is 64bits when mtd-utils are not compile with
WITHOUT_LARGEFILE) is calculated like that:
offset = nb * size;
But nb and size are int, so on 32bits platforms, there's a possible
overflow.
So, it should be replace with:
offset = (off_t)nb * size;
If WITHOUT_LARGEFILE is defined, there still be an overflow, but it's
what we want, right ?

The ioctl UBI_IOCATT has been extended with max_beb_per1024 parameter.
This parameter is used for adjusting the "maximum expected number of
bad blocks per 1024 blocks" for each mtd device.
The number of physical erase blocks (PEB) that UBI will reserve for bad
block handling is now:
whole_flash_chipset__PEB_number * max_beb_per1024 / 1024
This means that for a 4096 PEB NAND device with 3 MTD partitions:
mtd0: 512 PEB
mtd1: 1536 PEB
mtd2: 2048 PEB
the commands:
ubiattach -m 0 -d 0 -b 20 /dev/ubi_ctrl
ubiattach -m 1 -d 1 -b 20 /dev/ubi_ctrl
ubiattach -m 2 -d 2 -b 20 /dev/ubi_ctrl
will attach mtdx to UBIx and reserve:
80 PEB for bad block handling on UBI0
80 PEB for bad block handling on UBI1
80 PEB for bad block handling on UBI2
=> for the whole device, 240 PEB will be reserved for bad block
handling.
This may seems a waste of space, but as far as the bad blocks can appear
every where on a flash device, in the worst case scenario they can
all appear in one MTD partition.
So the maximum number of expected erase blocks given by the NAND
manufacturer should be reserve on each MTD partition.

mtdoffset is being tested against mtd.size in the outer two loops, but
the third nested one does not test against it.
In case of a bad block we'll try to access an out of bounds offset in
the next MEMGETBADBLOCK ioctl, which will fail with EINVAL.
In case mtdoffset is indeed larger than the partition size, we need to
bail, since there are not enough "good" blocks to complete the write.

findutils v4.1.x does not have the `-exec CMD {} +' syntax. We can just as
easily use the `-exec CMD {} \;' syntax. However, it will launch a lot more
`rm' processes, so we only use it if the first form fails with an error.
This isn't a perfect solution (`find -exec +' can fail for other reasons)
but it works well enough.
This problem manifests itself in RHEL 4, findutils 4.1.20:
$ make clean

find: missing argument to `-exec'
