The problem is caused by the incorrect handling of the parent inode's
i_nlink count for the dentry to be RENAME_EXCHANGED. There are 3 cases
to consider. Assume we want to RENAME_EXCHANGE struct dentry *a and
struct dentry *b, and inode_a is pointed to by dentry_a, inode_b is
pointed to by dentry_b:
1. If inode_a is a directory, but inode_b isn't, then we must decrease
the i_nlink count of old_dir_i, and increase the i_nlink of new_dir_i.
2. If inode_a isn't a directory, but inode_b is a directory, then we
must increase the i_nlink of old_dir_i, and decrease the i_nlink count
of new_dir_i.
3. If the types of inode_a and inode_b are the same, we don't change the
i_nlink for either old_dir_i or new_dir_i.

The RouterBOOT bootloader does not care where the kernel lives in the SPI
flash, all that matters is that the kernel is wrapped in the custom yaffs
container as generated by kernel2minor.
This container has a fixed signature as follows:
00000000 00 00 00 01 00 00 00 01 ff ff 6b 65 72 6e 65 6c |..........kernel|
This patch adds mtdsplit support for identifying that signature and
triggering the search for the rootfs. rootfs is expected at EB boundary since
we use wget mtd_find_rootfs_from(). We make no use of the yaffs file size
field because it contains invalid data in the image generated by kernel2minor.

This patch adds supports for the WNR2000v1 board with 4MB flash, and
produces device-specific factory, rootfs, and sysupgrade files for the
WNR2000v1. This board is errorneously claimed as supported on the OpenWRT
wiki as AP81, but AP81 image would not work because of APT81 image
requiring having 8MB of flash, while WNR2000v1 has only 4MB.
The image requires the u-boot bootloader to be modified to fuhry's
bootloader first.
Short specification:
- CPU: Atheros AR9132
- 4x 10/100 Mbps Ethernet, 1x WAN 10/100 Mbps
- 4 MB of Flash
- 32 MB of RAM
- UART header (J1) on board
- 1x button
Factory/Initial flash instructions:
- Set up a TFTP server on your local machine.
- Download the uImage for ar71xx-generic and the rootfs image for
ar71xx-generic-wnr2000 and save in the tftp server root.
- Gain serial access to the router via the UART port (telnetenable over
the network only won't work!).
- Upgrade the u-boot bootloader to fuhry's version by running the
script: http://fuhry.com/b/wnr2000/install-repart.sh
- When the router restarts, interrupt u-boot and gain access to u-boot command line.
- Repartititon the board and flash initial uImage and rootfs as follow.
Commands to type in u-boot:
# tells u-boot that we have a tftp server on 192.168.1.10
setenv serverip 192.168.1.10
# tells u-boot that the router should take the address 192.168.1.1
setenv ipaddr 192.168.1.1
# erase the region from 0x050000-0x3f0000
erase 0xbf050000 +0x3A0000
# loads sqfs.bin on TFTP server, and put it to memory address 0x81000000
tftpboot 0x81000000 sqfs.bin
# it will tell you the length of sqfs.bin in hex, let's say ZZZZZZ
# copy bit by bit 0xZZZZZZ bytes from offset 0x050000
cp.b 0x81000000 0xbf050000 0xZZZZZZ
# same to the uImage.bin, write it right next to sqfs.bin
# again, 0xYYYYYY is the length that tftpboot reports
tftpboot 0x81000000 uImage.bin
cp.b 0x81000000 0xbf2a0000 0xYYYYYY
# We need to tell the kernel what board it is booting into, and where to find the partitions
setenv bootargs "board=WNR2000 console=ttyS0,115200 mtdparts=spi0.0:256k(u-boot)ro,64k(u-boot-env)ro,3712k(firmware),64k(art)ro rootfstype=squashfs,jffs2 noinitrd"
# Tell u-boot where to find the uImage
setenv bootcmd "bootm 0xbf2a0000"
# Tell u-boot to save parameters to the u-boot-env partitions
saveenv
# Reset the board
reset
Tested on:
- WNR2000v1 board.
- Initial flash works.
Known bugs:
- I don't know why factory image doesn't work on initial flash on stock
firmware in u-boot recovery mode while it should.
- Sysupgrade does not yet work, if you do -f it will mess up your
installation (requiring a reinstall of sqfs and uImage).
