fs: implement size/fatsize/ext4size

2014-08-09T15:16:57Z

These commands may be used to determine the size of a file without actually reading the whole file content into memory. This may be used to determine if the file will fit into the memory buffer that will contain it. In particular, the DFU code will use it for this purpose in the next commit.

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
