* ext4: free allocations by parse_path()Stephen Warren2015-09-11-2/+6
| | | | | | | | | | | | | | parse_path() malloc()s the entries in the array it's passed. Those allocations must be free()d by the caller, ext4fs_get_parent_inode_num(). Add code to do this. For this to work, all the array entries must be dynamically allocated, rather than a mix of dynamic and static allocations. Fix parse_path() not to over-write arr[0] with a pointer to statically allocated data.

* ext4: avoid calling ext4fs_mount() twice, which leaksStephen Warren2015-09-11-9/+0
| | | | | | | | | | | | | ext4_write_file() is only called from the "fs" layer, which calls both ext4fs_mount() and ext4fs_close() before/after calling ext4_write_file(). Fix ext4_write_file() not to call ext4fs_mount() again, since the mount operation malloc()s some RAM which is leaked when a second mount call over-writes the pointer to that data, if no intervening close call is made.

* FIX: fat: Provide correct return code from disk_{read|write} to upper layersŁukasz Majewski2015-09-11-4/+18
| | | | | | | | | | | | | | | | | | | | | | It is very common that FAT code is using following pattern: if (disk_{read|write}() < 0) return -1; Up till now the above code was dead, since disk_{read|write) could only return value >= 0. As a result some errors from medium layer (i.e. eMMC/SD) were not caught. The above behavior was caused by block_{read|write|erase} declared at struct block_dev_desc (@part.h). It returns unsigned long, where 0 indicates error and > 0 indicates that medium operation was correct. This patch as error regards 0 returned from block_{read|write|erase} when nr_blocks is grater than zero. Read/Write operation with nr_blocks=0 should return 0 and hence is not considered as an error.

* Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h headerSimon Glass2015-09-11-0/+4

* Move malloc_cache_aligned() to its own headerSimon Glass2015-09-11-0/+5
| | | | | | | | | | | | | | | | | | | At present malloc.h is included everywhere since it recently was added to common.h in this commit: 4519668 mtd/nand/ubi: assortment of alignment fixes This seems wasteful and unnecessary. We have been trying to trim down common.h and put separate functions into separate header files and that change goes in the opposite direction. Move malloc_cache_aligned() to a new header so that this can be avoided. The header would perhaps be better named as alignmem.h but it needs to be included after common.h and people might be confused by this. With the name memalign.h it fits nicely after malloc() in most cases. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>
* fat: handle paths that include ../Stephen Warren2015-09-11-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FAT code contains a special case to parse the root directory. This is needed since the root directory location/layout on disk is special cased for FAT12/16. In particular, the location and size of the FAT12/16 root directory is hard-coded and contiguous, whereas all FAT12/16 non-root directories, and all FAT32 directories, are stored in a non-contiguous fashion, with the layout represented by a linked-list of clusters in the FAT. If a file path contains ../ (for example /extlinux/../bcm2835-rpi-cm.dtb), it is possible to need to parse the root directory for the first element in the path (requiring application of the special case), then a sub- directory (in the general way), then re-parse the root directory (again requiring the special case). However, the current code in U-Boot only applies the special case for the very first path element, and never for any later path element. When reparsing the root directory without applying the special case, any file in a sector (or cluster?) other than the first sector/cluster of the root directory will not be found. This change modifies the non-root-dir-parsing loop of do_fat_read_at() to detect if it's walked back to the root directory, and if so, jumps back to the special case code that handles parsing of the root directory. This change was tested using sandbox by executing: ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/.." ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/../" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/../backup" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/../backup/" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/../backup/.." ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/../backup/../" ./u-boot -c "host bind 0 ../sd-p1.bin; load host 0:0 0 /bcm2835-rpi-cm.dtb" ./u-boot -c "host bind 0 ../sd-p1.bin; load host 0:0 0 /extlinux/../bcm2835-rpi-cm.dtb" ./u-boot -c "host bind 0 ../sd-p1.bin; load host 0:0 0 /backup/../bcm2835-rpi-cm.dtb" ./u-boot -c "host bind 0 ../sd-p1.bin; load host 0:0 0 /extlinux/..backup/../bcm2835-rpi-cm.dtb" ./u-boot -c "host bind 0 ../sd-p1.bin; load host 0:0 0 /extlinux/../backup/../bcm2835-rpi-cm.dtb" (/extlinux and /backup are in different sectors so trigger some different cases, and bcm2835-rpi-cm.dtb is in a sector of the root directory other than the first). In all honesty, this change is a bit of a hack, using goto and all. However, as demonstrated above it appears to work well in practice, is quite minimal, likely doesn't introduce any risk of regressions, and hopefully doesn't introduce any maintenance issues. The correct fix would be to collapse the root and non-root loops in do_fat_read_at() and get_dentfromdir() into a single loop that has a small special-case when moving from one sector to the next, to handle the layout difference of root/non-root directories. AFAIK all other aspects of directory parsing are identical. However, that's a much larger change which needs significantly more thought before it's implemented.

| | | | | | | | | | | | | | | | | | | | | | | | | | http://lists.denx.de/pipermail/u-boot/2012-September/134347.html allows for reading files in chunks from the shell. When this feature is used to read past the end of a file an error was returned instead of returning the bytes read up to the end of file. Thus the following fails in the shell: offset = 0 len = chunksize do read file, offset, len write data until bytes_read < len The patch changes the behaviour to printing an informational message and returning the actual read number of bytes aka read(2) behaviour for convenient use in U-Boot scripts.

* JFFS2: Use merge sort when parsing filesystemMark Tomlinson2015-08-12-35/+69
| | | | | | | | | | | | | When building the file system the existing code does an insertion into a linked list. It attempts to speed this up by keeping a pointer to where the last entry was inserted but it's still slow. Now the nodes are just inserted into the list without searching through for the correct place. This unsorted list is then sorted once using mergesort after all the entries have been added to the list. This speeds up the scanning of the flash file system considerably.

* JFFS2: Use CLEANMARKER to reduce scanning timeMark Tomlinson2015-08-12-0/+25
| | | | | | | | | | | | If a sector has a CLEANMARKER at the beginning, it indicates that the entire sector has been erased. Therefore, if this is found, we can skip the entire block. This was not being done before this patch. The code now does the same as the kernel does when encountering a CLEANMARKER. It still checks that the next few words are FFFFFFFF, and if so, the block is assumed to be empty, and so is skipped. Signed-off-by: Mark Tomlinson <mark.tomlinson@alliedtelesis.co.nz>
* JFFS2: Change scansize to match linux kernelMark Tomlinson2015-08-12-1/+1
| | | | | | | | | | | | The scan code is similar to the linux kernel, but the kernel defines a much smaller size to scan through before deciding a sector is blank. Assuming that what is in the kernel is OK, make these two match. On its own, this change makes no difference to scanning of any sectors which have a clean marker at the beginning, since the entire sector is not blank.

* JFFS2: Improve speed reading flash filesMark Tomlinson2015-08-12-6/+21
| | | | | | | | | | | | | | jffs2_1pass_read_inode() would read the entire data for each node in the filesystem, regardless of whether it was part of the file to be loaded or not. By only reading the header data for an inode, and then reading the data only when it is found to be part of the file to be loaded, much copying of data is saved. jffs2_1pass_list_inodes() read each inode for every file in the directory into a buffer. By using NULL as a buffer pointer, NOR flash simply returns a pointer, and therefore avoids a memory copy. Signed-off-by: Mark Tomlinson <mark.tomlinson@alliedtelesis.co.nz>
* JFFS2: Only list each directory entry onceMark Tomlinson2015-08-12-5/+33
| | | | | | | | | | | | | If multiple versions of a file exist, only the most recent version should be used. The scheme to write 0 for the inode in older versions did not work, since this would have required writing to flash. The only time this caused an issue was listing a directory, where older versions of the file would still be seen. Since the directory entries are sorted, just look at the next entry in the list, and if it's the same move to that entry instead. Signed-off-by: Mark Tomlinson <mark.tomlinson@alliedtelesis.co.nz>
* JFFS2: Speed up and fix comparison functionsMark Tomlinson2015-08-12-40/+47
| | | | | | | | | | | | | | | Copying complete nodes from flash can be slow if the flash is slow to read. By only reading the data needed, the sorting operation can be made much faster. The directory entry comparison function also had a two bugs. First, it did not ensure the name was copied, so the name comparison may have been faulty (although it would have worked with NOR flash). Second, setting the ino to zero to ignore the entry did not work, since this was either writing to a temporary buffer, or (for NOR flash) directly to flash. Either way, the change was not remembered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The present fat implementation ignores FAT16 long name directory entries which aren't placed in a single sector. This was becouse of the buffer was always filled by the two sectors, and the loop was made also for two sectors. If some file long name entries are stored in two sectors, the we have two cases: Case 1: Both of sectors are in the buffer - all required data for long file name is in the buffer. - Read OK! Case 2: The current directory entry is placed at the end of the second buffered sector. And the next entries are placed in a sector which is not buffered yet. Then two next sectors are buffered and the mentioned entry is ignored. - Read fail! This commit fixes this issue by: - read two sectors after loop on each single is done - keep the last used sector as a first in the buffer before the read of two next The commit doesn't affects the fat32 imlementation, which works good as previous.

Instead of defining __UBOOT__ in each source file, passing it from the top Makefile would be easier.

| | | | | | | | | | | | | | | | - move linux specific defines from usb and video code into linux/compat.h - move common linux specific defines from include/ubi_uboot.h to linux/compat.h - add for new mtd/ubi/ubifs sync new needed linux specific defines to linux/compat.h Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Marek Vasut <marex@denx.de> Cc: Anatolij Gustschin <agust@denx.de> [trini: Add spin_lock_irqsave/spin_unlock_irqrestore dummies from usb/lin_gadet_compat.h] Signed-off-by: Tom Rini <trini@ti.com>
* fs: implement size/fatsize/ext4sizeStephen Warren2014-08-09-0/+58
| | | | | | | | | | 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.

* catch wrong load address passed to fatload / ext2loadPavel Machek2014-07-22-1/+4
| | | | | | | | If filename is passed instead of address to ext2load or fatload, u-boot silently accepts that, and uses 0 for load address and default filename from environment. That is confusing, display help instead. Signed-off-by: Pavel Machek <pavel@denx.de>
* yaffs2: preprocessor cleanupJeroen Hofstee2014-07-18-11/+10
| | | | | | | | | Current code uses the preprocessor to change an else case to a statement without any if condition at all. Although this works, change the optional code to return early, so all optional code is contained within a single #ifdef. Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
* yaffs2: cosmetic: remove self assignmentsJeroen Hofstee2014-07-18-22/+1
| | | | | | | | | Remove self assignments which is just dead code to prevent compiler warnings about non used arguments. For u-boot this does not prevent any warning though, on the contrary it actual introduces warnings when compiling with clang. Remove them. Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
* fs: ext4: fix writing zero-length filesStephen Warren2014-06-19-3/+1
| | | | | | | | | | | | | ext4fs_allocate_blocks() always allocates at least one block for a file. If the file size is zero, this causes total_remaining_blocks to underflow, which then causes an apparent hang while 2^32 blocks are allocated. To solve this, check that total_remaining_blocks is non-zero as part of the loop condition (i.e. before each loop) rather than at the end of the loop.

* jffs2:jffs2_1pass.c: remove double bracesJeroen Hofstee2014-06-11-1/+1
| | | | | | | | | Clang interpretes an if condition like  "if ((a = b) == NULL) as it tries to assign a value in a statement. Hence if you do "if ((something)) it warns you that you might be confused. Hence drop the double braces for plane if statements. Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
