2012-01-05FAT: update the second FAT when writing a fileDonggeun Kim
After susccessful write to the FAT partition, fsck program may print warning message due to different FAT, provided that the filesystem supports two FATs. This patch makes the second FAT to be same with the first one when writing a file. Signed-off-by: Donggeun Kim <dg77.kim@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2012-01-05fs/fat: Improve error handlingKyle Moffett
The FAT filesystem fails silently in inexplicable ways when given a filesystem with a block-size that does not match the device sector size. In theory this is not an unsupportable combination but requires a major rewrite of a lot of the filesystem. Until that occurs, the filesystem should detect that scenario and display a helpful error message. This scenario in particular occurred on a 512-byte blocksize FAT fs stored in an El-Torito boot volume on a CD-ROM (2048-byte sector size). Additionally, in many circumstances the ->block_read method will not return a negative number to indicate an error but instead return 0 to indicate the number of blocks successfully read (IE: None). The FAT filesystem should defensively check to ensure that it got all of the sectors that it asked for when reading. Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com>
2012-01-05fs/fat: Fix FAT detection to support non-DOS partition tablesKyle Moffett
The FAT filesystem code currently ends up requiring that the partition table be a DOS MBR, as it checks for the DOS 0x55 0xAA signature on the partition table (which may be Mac, EFI, ISO9660, etc) before actually computing the partition offset. This fixes support for accessing a FAT filesystem in an ISO9660 boot volume (El-Torito format) by reordering the filesystem checks and reading the 0x55 0xAA "DOS boot signature" and FAT/FAT32 magic number from the first sector of the partition instead of from sector 0.

2011-12-20FAT: fix some issues in FAT write support codeAnatolij Gustschin
Writing a file to the FAT partition didn't work while a test using a CF card. The test was done on mpc5200 based board (powerpc). There is a number of problems in FAT write code: Compiler warning: fat_write.c: In function 'file_fat_write': fat_write.c:326: warning: 'counter' may be used uninitialized in this function fat_write.c:326: note: 'counter' was declared here 'l_filename' string is not terminated, so a file name with garbage at the end is used as a file name as shown by debug code. Return value of set_contents() is not checked properly so actually a file won't be written at all (as checked using 'fatls' after a write attempt with 'fatwrite' command). do_fat_write() doesn't return the number of written bytes if no error happened. However the return value of this function is used to show the number of written bytes in do_fat_fswrite(). The patch adds some debug code and fixes above mentioned problems and also fixes a typo in error output. NOTE: after a successful write to the FAT partition (under U-Boot) the partition was checked under Linux using fsck. The partition needed fixing FATs: -bash-3.2# fsck -a /dev/sda1 fsck 1.39 (29-May-2006) dosfsck 2.11, 12 Mar 2005, FAT32, LFN FATs differ but appear to be intact. Using first FAT. Performing changes.

2011-10-26FAT: Add FAT write featureDonggeun Kim
In some cases, saving data in RAM as a file with FAT format is required. This patch allows the file to be written in FAT formatted partition. The usage is similar with reading a file. First, fat_register_device function is called before file_fat_write function in order to set target partition. Then, file_fat_write function is invoked with desired file name, start ram address for writing data, and file size.

2011-10-25ext2: Cache line aligned partial sector bounce bufferAnton staaf
Currently, if a device read request is done that does not begin or end on a sector boundary a stack allocated bounce buffer is used to perform the read, and then just the part of the sector that is needed is copied into the users buffer. This stack allocation can mean that the bounce buffer will not be aligned to the dcache line size. This is a problem when caches are enabled because unaligned cache invalidates are not safe. This patch uses ALLOC_CACHE_ALIGN_BUFFER to create a stack allocated cache line size aligned bounce buffer.

2011-04-02fat32 root directory handlingErik Hansen
Fat directory handling didn't check reaching the end of the root directory. It relied on a stop condition based on a directory entry with a name starting with a '\0' character. This check in itself is wrong ('\0' indicates free entry, not end_of_directory) but outside the scope of this fix. For FAT32, the end of the rootdir is reached when the end of the cluster chain is reached. The code didn't check this condition and started to read an incorrect cluster. This caused a subsequent read request of a sector outside the range of the usb stick in use. On its turn, the usb stick protested with a stall handshake. Both FAT32 and non-FAT32 (FAT16/FAT12) end or rootdir checks have been put in. Signed-off-by: Erik Hansen <erik@makarta.com>

2010-12-03UBIFS: Change ubifsload to not read beyond the requested sizeStefan Roese
Until now ubifsload pads the destination with 0 up to a multiple of UBIFS_BLOCK_SIZE (4KiB) while reading a file to memory. This patch changes this behaviour to only read to the requested length. This is either the file length or the length/size provided as parameter to the ubifsload command. Signed-off-by: Stefan Roese <sr@denx.de>

2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
2010-10-29Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk
By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

2010-10-20FAT: buffer overflow with FAT12/16Stefano Babic
Last commit 3831530dcb7b71329c272ccd6181f8038b6a6dd0a was intended "explicitly specify FAT12/16 root directory parsing buffer size, instead of relying on cluster size". Howver, the underlying function requires the size of the buffer in blocks, not in bytes, and instead of passing a double sector size a request for 1024 blocks is sent. This generates a buffer overflow with overwriting of other structure (in the case seen, USB structures were overwritten).
