* fritz-tools: fix returning wrong values due to strncmp usageDaniel Kestrel2021-08-082-2/+2
| | | | | | | | | | | | | | | | | 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.

* fritz_tffs_read: get tffs size from input fileMathias Kresin2017-06-241-3/+7
| | | | | | | | | | Use the size of the input file as maximum tffs size instead of a fixed value. The tffs on a AVM Fritz 300E can be up to 512KByte for example. Fixes a read error for the AVM Fritz 3370 where the tffs partition size is 64Kbyte and smaller than the former default value of 256KByte. Signed-off-by: Mathias Kresin <dev@kresin.me>

* firmware: rework fritz-tools packageMathias Kresin2017-04-085-0/+741
Split the fritz-tools into subpackages. fritz_tffs_read is usefull for all Fritz boards where fritz-cal_extract is only required for the Fritz 4040 at the moment. Rename the tffs related binary to the more catchy name fritz_tffs and move the whole package to utilities since the package doesn't really provide a firmware file. Make the fritz-tools available for all targets and build them shared. The tffs is used by avm on lantiq and ar71xx as well.
