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:ext4:write:fix: Reinitialize global variables after updating a file

2014-05-12T20:31:50Z

This bug shows up when file stored on the ext4 file system is updated. The ext4fs_delete_file() is responsible for deleting file's (e.g. uImage) data. However some global data (especially ext4fs_indir2_block), which is used during file deletion are left unchanged. The ext4fs_indir2_block pointer stores reference to old ext4 double indirect allocated blocks. When it is unchanged, after file deletion, ext4fs_write_file() uses the same pointer (since it is already initialized - i.e. not NULL) to return number of blocks to write. This trunks larger file when previous one was smaller. Lets consider following scenario: 1. Flash target with ext4 formatted boot.img (which has uImage [*] on itself) 2. Developer wants to upload their custom uImage [**] - When new uImage [**] is smaller than the [*] - everything works correctly - we are able to store the whole smaller file with corrupted ext4fs_indir2_block pointer - When new uImage [**] is larger than the [*] - theCRC is corrupted, since truncation on data stored at eMMC was done. 3. When uImage CRC error appears, then reboot and LTHOR/DFU reflashing causes proper setting of ext4fs_indir2_block() and after that uImage[**] is successfully stored (correct uImage [*] metadata is stored at an eMMC on the first flashing). Due to above the bug was very difficult to reproduce. This patch sets default values for all ext4fs_indir* pointers/variables. Signed-off-by: Lukasz Majewski

Code responsible for handling situation when ext4 has block size of 1024B can be ordered to take less space. This patch does that for ext4 common and write files. Signed-off-by: Lukasz Majewski

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

arm: Switch to -mno-unaligned-access when supported by the compiler

2014-02-26T20:19:32Z

When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.
