* Fix bug in writefat functionAmeya Thakur2015-10-071-1/+1
| | | | | | | The readfat call returns 1 in case of success and 0 in case of failure. writefat now correctly checks the return value of the call. Change-Id: I95d09ec347ac5f2f751bb40a046f2567a1694422
* Correct free size calculationxiaogang2015-10-071-16/+40
| | | | | | | | | When clearchain or trunc, move the fatcache to rb_free_root tree. This way writefat will generate correct FAT table. When clearchain or trunc, re-calculate the free sectors of filesystem. Change-Id: I3b480ab161db5777e6f948f780b6bdaf3ada9467
* Do not return error if there is no FAT after fresh formatrockiec2015-10-071-2/+6
| | | | | | | After format all clusters are free, so don't return error. This fixes fsck fail on clean FAT16 partitions. Change-Id: Ib21d000eaad1f84d6182c19cbb81cd3a1d069211

* | Fix an out of boundary access in fat.cEthan2010-07-211-10/+12
|/ | | | | | | | | | | | From SD Specifications Part2 - File System For Next Free Cluster, value FFFFFFFFh indicates that there exists no information about the first available (free) cluster. It is a valid value. However fat.c doesn't check the value before use it as array index. This will cause fsck_msdos coredump with some micro sd cards Change-Id: Ibdec1655399d95c3ca98a4f4aaed1fd9bf459f33 Signed-off-by: Ethan <ethan.too@gmail.com>
