Hello all,

Buildroot recently bumped the mtd-utils package from version 1.3.1 to 1.4.0.

With the mkfs.jffs2 utility in 1.3.1 I am able to create rootfs.jffs images that
work fine on my i.mx35 arm system.  But, with the 1.4.0 version all the images
do not work.

With the 1.4.0 built images I get messages like this during the kernel boot:

jffs2_scan_eraseblock(): Node at 0x00000000 {0x1985, 0x2003, 0x0000000c) has invalid CRC 0x813c6fd8 (calculated 0xe41eb0b1)

Further such events for this erase block will not be printed
Old JFFS2 bitmask found at 0x00000078
You cannot use older JFFS2 filesystems with newer kernels
Empty flash at 0x0000a46c ends at 0x0000a470

And, if I check the images with jffs2dump I get stuff like:

Wrong hdr_crc  at  0x0001f808, 0x783f44d2 instead of 0x1d1d9bbb
Wrong bitmask  at  0x0001f80c, 0x07f3
Empty space found from 0x0001fffc to 0x00020000

Any ideas what could be wrong with the 1.4.0 release?

Thanks,
Hartley

Could you please bisect the mtd-utils.git tree and find the offending
commit.

With big endian atleast, jffs2dump complains about invalid hdr_crc on
1.4.0, but it's working on HEAD. A bisect shows that the commit fixing
it was Mike's:

commit b864c387e8f16273aad1453d6457d847e29c3d25
Author: Mike Frysinger <vapier@gentoo.org>
Date:   Wed Sep 22 22:32:56 2010 -0400

    mtd-utils: clean up zlib.h usage a bit
    
    Hide zlib's crc32 in compr_zlib.c and mkfs.ubifs/compr.c.
    
    jffs2reader.c and mkfs.jffs2.c don't actually use zlib, so punt the
    include from the file.
    
    mkfs.jffs2.c is implicitly using crc32 from zlib.h instead of the
    local mtd_crc32, so fix the local usage.  otherwise we get warnings
    about undefined crc32 because the file was redirecting the prototype.

Hartley, that commit applies OK to 1.4.0, could you give it a try?

Artem: Time for a v1.4.1 release?

Thanks. If it works, I'll back-port Mike's patch to 1.4.0 and tag it as
1.4.1. So 1.4.1 won't include tons of irrelevant commits.

Great. An easy way to test:

git checkout v1.4.0
make WITHOUT_XATTR=1
./mkfs.jffs2 -e 0x20000 -b -s 0x1000 -d include -o test.jffs2
/usr/sbin/jffs2dump -b -c test.jffs2|head -n 4
Wrong hdr_crc  at  0x00000000, 0x954203f1 instead of 0xf060dc98
Wrong bitmask  at  0x00000004, 0x0000
Wrong hdr_crc  at  0x0000000c, 0xd10532a2 instead of 0xb427edcb
Wrong bitmask  at  0x00000010, 0x0000

git cherry-pick b864c387e8f1
make WITHOUT_XATTR=1
./mkfs.jffs2 -e 0x20000 -b -s 0x1000 -d include -o test.jffs2

Done. You can find v1.4.1 tag, tarball, and announcement in the "news"
section of the web site.

Thanks, but the 1.4.1 tarball is screwed - It contains a bunch of build
files which breaks the build if they aren't removed first.
