Hello

This is a bug report concerning the erase-block-summary (EBS) feature:

We're using JFFS2 as our root filesystem on our embedded device. Our 
device is a custom hardware based around a Hynix ARM H7202 processor. 
We're using Intel Strata Flash (NOR). See any of the attached kernel log 
files for more information.

JFFS2 works fine so far (without EBS). We hope to improve the mount time 
with the EBS feature. We're currently using the 2.6.13 kernel, and I 
patched the MTD subsystem with a current version of the MTD CVS 
(09-09-2005). The patched kernel boots happily when EBS is disable, both 
with sumtool-processed images and with normal non-processed images. (see 
without-ebs-with-sumtool.txt and without-ebs-without-sumtool.txt logfiles).

As soon as I enable EBS I get a kernel panic (see 
with-ebs-with-sumtool.txt logfile). I'm pretty sure that the image is 
not corrupt, as the first two tests with EBS disable show. Also, I'm 
using a script to upload new kernel and rootfs images. So there should 
not have been anything gone wrong during the copy process!

Here are the steps I used to build the root filesystem:

mkfs.jffs2 -p 6291456 -d ./rootfs -e 128KiB -l -v -U -D 
./devicetable.txt -o ./rootfs.tmp
sumtool -i ./rootfs.tmp -o ./rootfs.img -e 128KiB -l -v

If you need more information, just let me know.

Best regards,
Simon Kallweit

Re: Bugreport: JFFS2 + EBS

[Ferenc Havasi]

Hi Simon!

Let me explain what I see in your log.

The log of "with sumtooled image but without EBS kernel support" shows a 
lot of "unknow but compatible node". These nodes are the summary nodes. 
They are localated at the end of the used (and already closed) erase 
blocks. The first one is at 0x0001e864 (at the end of erase block 
0x00000000-0x0001FFFF), the last one is 0x0029eed8 (at the end of erase 
block 0x00280000-0x0029FFFF).

With EBS support the mounting process is modified. First the scanning 
process read the end of the erase block. If it is valid summary 
information it is no need to read the whole erase block, if not than the 
original (full) scanning process is applied for that erase block.

See the first error message:

 > jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 
0x002a0000: 0x00b0 instead

It means that the problem is with the first erase block which has no 
summary, so the full scanning method is applied. It try to find valid 
JFFS2 nodes, but it is not succesfull, every word is 0x00b0.

Something similar happened with Pete. The original JFFS2 worked at him, 
but summary did not. We was not able to find the problem, because his 
image worked at us. Finally he found the bug. It was not in the JFFS2 
but in his flash driver. Summary makes some "tricks": read from the end 
of the erase block, if there is no summary go back to the begining of 
it. If the flash driver buggy than it doesn't like it.

I suggest you should dump what is at 0x002a0000, and later (without 
mounting, for example with jffs2dump tool). I suppose it should not be 
0x00b0 - but your flash driver give it back, after tracking back. So my 
first tip is that there is a bug in your flash driver.

You also may send us (or make it downloadable for us) your image to 
analize (and try if it works at us).

I am also curious what happen with EBS support but without sumtool. I 
should mount without problem because it recognise it is not summarized 
image, so apply the original scanning method.

And finaly it may also be more informative to set the JFFS2 debug level 
1 to get more debug message (the summary debug messages is the most 
important for us)

Bye,
Ferenc

I wonder, why don't you do the same trick that I did for fragtree build 
messages and the like, (see debug.h) to be able on/off your summary 
messages independently. Believe me, this is very handy to have a 
possibility to filter unneeded flood.

We are already using it. I rewrote our debug messages to use your debug 
stuff before commiting the patch, and added a "#define 
JFFS2_DBG_SUMMARY_MESSAGES" into debug.h. (or do you think about an 
other thing?)

I agree, it is really usefull.

No, I jus did not look at the last debug.h :-) pardon.

Hm, interesting.

This is 2.6.13 with mtd-cvs from yesterday (actually I produced the
error with other versions also IIRC, trying to reproduce actually):

Kernel says:

JFFS2 warning: (1) jffs2_sum_scan_sumnode: Summary node crc error, skipping summary information.

Further such events for this erase block will not be printed

a dozen of times...

Bootloader says:

emacs on flashed image says:
00000000: 8519 0320 0c00 0000 b1b0 1ee4 8519 01e0

So all is fine. Where is the Kernel reading 0x00b0 from?

Hm, I will search the archive then... Same Bug seems to be here.
Is the mapping code in maps meant by "flashdriver"?

> I am also curious what happen with EBS support but without sumtool.

jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000000:
0x00b0 instead

and so on ...

Doesn't either :(

What a pity, he did not elaborate on that.
I use intel with cfi_cmdset_0001.c.

What I also have with the 2.6.13 Kernel is:

Inode #278 was a directory with children - removing those too...

What does that mean?

Misteriously at the same time mounting virgin jffs2 on 2.6.12 broke
and the XIP in 2.6.13 is not working anymore either. May be our
maps/scb9328 is involved and has to be changed somewhere...
