When having two keys that start with the same characters and the second key just has one character more nand_tffs_read and tffs_read return the wrong value for the longer key. This is due to the usage of strncmp in combination with the length of the shorter key which is usually first in the list before the longer key and when strncmp matches, the search is stopped. The problem only occurs when the length of the two keys is different, not if just the last character is different. The fix is to use strcmp and as such it will only return the value if the key (name) and the key to look for (namefilter) have the same value and length. A sample case returning wrong values is when keys macwlan and macwlan2 are defined and querying macwlan2 returns the value for macwlan. Signed-off-by: Daniel Kestrel <kestrel1974@t-online.de> |

Userspace utilties for accessing TFFS (a name-value storage usually found in AVM Fritz!Box based devices)
Building
mkdir build
cd build
cmake /path/to/fritz_tffs_tools
make
Usage
All command line parameters are documented:
fritz_tffs_read -h
Show all entries from a TFFS partition dump (in the format: name=value):
fritz_tffs_read -i /path/to/tffs.dump -a
Read a TFFS partition and show all entries (in the format: name=value):
fritz_tffs_read -i /dev/mtdX -a
Output only the value of a specific key (this will only show the value):
fritz_tffs_read -i /dev/mtdX -n my_ipaddress
