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.

2011-10-01fat: replace LINEAR_PREFETCH_SIZE with PREFETCH_BLOCKSSergei Shtylyov
Currently in do_fat_read() when reading FAT sectors, we have to divide down LINEAR_PREFETCH_SIZE by the sector size, whereas it's defined as 2 sectors worth of bytes.

2011-10-01fat: root directory cluster only makes sense for FAT32Sergei Shtylyov

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>

2010-11-17Switch 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>

2010-10-20FAT: 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).

2010-10-12VFAT: fix processing of scattered long file name entriesMikhail Zolotaryov
The U-Boot code has the following bugs related to the processing of Long File Name (LFN) entries scattered across several clusters/sectors : 1) get_vfatname() function is designed to gather scattered LFN entries by cluster chain processing - that doesn't work for FAT12/16 root directory. In other words, the function expects the following input data: 1.1) FAT32 directory (which is cluster chain based); OR 1.2) FAT12/16 non-root directory (which is also cluster chain based); OR 1.3) FAT12/16 root directory (allocated as contiguous sectors area), but all necessary information MUST be within the input buffer of filesystem cluster size (thus cluster-chain jump is never initiated). In order to accomplish the last condition, root directory parsing code in do_fat_read() uses the following trick: read-out cluster-size block, process only first sector (512 bytes), then shift 512 forward, read-out cluster-size block and so on. This works great unless cluster size is equal to 512 bytes (in a case you have a small partition), or long file name entries are scattered across three sectors, see 4) for details. 2) Despite of the fact that get_vfatname() supports FAT32 root directory browsing, do_fat_read() function doesn't send current cluster number correctly, so root directory look-up doesn't work correctly. 3) get_vfatname() doesn't gather scattered entries correctly also is the case when all LFN entries are located at the end of the source cluster, but real directory entry (which must be returned) is at the only beginning of the next one. No error detected, the resulting directory entry returned contains a semi-random information (wrong size, wrong start cluster number and so on) i.e. the entry is not accessible. 4) LFN (VFAT) allows up to 20 entries (slots) each containing 26 bytes (13 UTF-16 code units) to represent a single long file name i.e. up to 520 bytes. U-Boot allocates 256 bytes buffer instead, i.e. 10 or more LFN slots record may cause buffer overflow / memory corruption. Also, it's worth to mention that 20+1 slots occupy 672 bytes space which may take more than one cluster of 512 bytes (medium-size FAT32 or small FAT16 partition) - get_vfatname() function doesn't support such case as well. The patch attached fixes these problems in the following way: - keep using 256 bytes buffer for a long file name, but safely prevent a possible buffer overflow (skip LFN processing, if it contains 10 or more slots). - explicitly specify FAT12/16 root directory parsing buffer size, instead of relying on cluster size. The value used is a double sector size (to store current sector and the next one). This fixes the first problem and increases performance on big FAT12/16 partitions; - send current cluster number (FAT32) to get_vfatname() during root directory processing; - use LFN counter to seek the real directory entry in get_vfatname() - fixes the third problem; - skip deleted entries in the root directory (to prevent bogus buffer overflow detection and LFN counter steps). Note: it's not advised to split up the patch, because a separate part may operate incorrectly. Signed-off-by: Mikhail Zolotaryov <lebon@lebon.org.ua>

2010-07-24FAT32: fix broken root directory handling.Wolfgang Denk
On FAT32, instead of fetching the cluster numbers from the FAT, the code assumed (incorrectly) that the clusters for the root directory were allocated contiguously. In the result, only the first cluster could be accessed. At the typical cluster size of 8 sectors this caused all accesses to files after the first 128 entries to fail - "fatls" would terminate after 128 files (usually displaying a bogus file name, occasionally even crashing the system), and "fatload" would fail to find any files that were not in the first directory cluster.

2010-01-15JFFS2: drop support for LZARI compression modeWolfgang Denk
Support for LZARI compression mode was added based on a MTD CVS snapshot of March 13, 2005. However, fs/jffs2/compr_lzari.c contains contradictory licensing terms: the original copyright clause says "All rights reserved. Permission granted for non-commercial use.", but later reference to the file 'LICENCE' in the jffs2 directory was added which says GPL v2 or later. As no boards ever used LZARI compression, and this file is also not present in recent MTD code, we resolve this conflict by removing the conflicting file and references to it. Also copy the referenced but missing file 'LICENCE' from the current MTD source tree. Signed-off-by: Wolfgang Denk <wd@denx.de>
2009-12-21move prototypes for gunzip() and zunzip() to common.hWolfgang Wegner
Prototype for gunzip/zunzip was only in lib_generic/gunzip.c and thus repeated in every file using it. This patch moves the prototypes to common.h and removes all prototypes distributed anywhere else. Signed-off-by: Wolfgang Wegner <w.wegner@astro-kom.de>
