fs/fat: correct FAT16/12 file finding in root dir

2014-05-12T20:31:51Z

When write a file into FAT file system, it will search a match file in root dir. So the find_directory_entry() will get the first cluster of root dir content and search the directory item one by one. If the file is not found, we will call get_fatent_value() to get next cluster of root dir via lookup the FAT table and continue the search. The issue is in FAT16/12 system, we cannot get root dir's next clust from FAT table. The FAT table only be use to find the clust of data aera in FAT16/12. In FAT16/12 if the clust is in root dir, the clust number is a negative number or 0, 1. Since root dir is located in front of the data area. Data area start clust #2. So the root dir clust number should < 2. This patch will check above situation before call get_fatenv_value(). If curclust is < 2, include minus number, we just increase one on the curclust since root dir is in continous cluster. The patch also add a sanity check for entry in get_fatenv_value().

fs: fat_write: fix the incorrect last cluster checking

2014-05-12T20:31:50Z

In fat_write.c, the last clust condition check is incorrect: if ((curclust >= 0xffffff8) || (curclust >= 0xfff8)) { ... ... } For example, in FAT32 if curclust is 0x11000. It is a valid clust. But on above condition check, it will be think as a last clust. So the correct last clust check should be: in fat32, curclust >= 0xffffff8 in fat16, curclust >= 0xfff8 in fat12, curclust >= 0xff8 This patch correct the last clust check. Signed-off-by: Josh Wu

fs: fat: Fix cache align error message in fatwrite

2014-05-12T19:19:45Z

Use of malloc of do_fat_write() causes cache error on ARM v7 platforms. Perhaps, the same problem will occur at any other CPUs. This replaces malloc with memalign to fix cache buffer alignment. Signed-off-by: Nobuhiro Iwamatsu Signed-off-by: Yoshiyuki Ito Tested-by: Hector Palacios

fat: implement exists() for FAT fs

This hooks into the generic "file exists" support added in an earlier patch, and provides an implementation for the FAT filesystem. Signed-off-by: Stephen Warren Acked-by: Simon Glass

fs: fat: don't call disk_write with zero sector num

2013-09-06T17:09:07Z

In the set_cluster() function, it will convert the buffer size to sector numbers. Then call disk_write() to write by sector. For remaining buffer, the size is less than a sector, call disk_write() again to write them in one sector. But if the total buffer size is less then one sector, the original code will call disk_write() with zero sector number. It is unnecessary. So this patch fix this. Now it will not call disk_write() if total buffer size is less than one sector. Signed-off-by: Josh Wu

fs/fat: Don't multiply fatsize with sector size
