* Various Makefiles: Add SPDX-License-Identifier tagsTom Rini2015-11-10-6/+1
| | | | | | | | | | | After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one. This adds tags to ones that lack them and converts a few that had full (or in one case, very partial) license blobs into the equivalent tag.

* fs/fat/fat_write: Fix management of empty filesBenoît Thébaudeau2015-10-11-21/+64
| | | | | | | | | | | | Overwriting an empty file not created by U-Boot did not work, and it could even corrupt the FAT. Moreover, creating empty files or emptying existing files allocated a cluster, which is not standard. Fix this by always keeping empty files clusterless as specified by Microsoft (the start cluster must be set to 0 in the directory entry in that case), and by supporting overwriting such files.

* fs/fat/fat_write: Fix buffer alignmentsBenoît Thébaudeau2015-10-11-14/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | set_cluster() was using a temporary buffer without enforcing its alignment for DMA and cache. Moreover, it did not check the alignment of the passed buffer, which can come directly from applicative code or from the user. This could cause random data corruption, which has been observed on i.MX25 writing to an SD card. Fix this by only passing ARCH_DMA_MINALIGN-aligned buffers to disk_write(), which requires the introduction of a buffer bouncing mechanism for the misaligned buffers passed to set_cluster(). By the way, improve the handling of the corresponding return values from disk_write(): - print them with debug() in case of error, - consider that there is an error is disk_write() returns a smaller block count than the requested one, not only if its return value is negative. After this change, set_cluster() and get_cluster() are almost symmetrical. Signed-off-by: Benoît Thébaudeau <benoit@wsystem.com>

* 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.

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.

* 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.

* 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.

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>

| | | | | | | | | | | | | | | 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.

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.

If given, it is stored in the env variable. - corrected typos - return error codes changes v1 -> v2: - fix return code of do_fs_uuid(..) - document do_fs_uuid(..) - implement fs_uuid_unsuported(..) be more consistent with the way other optional functionality works changes v2 -> v3: - change ext4fs_uuid(..) to make use of #if .. #else .. #endif construct to get rid of unreachable code Hit any key to stop autoboot: 0 => fsuuid fsuuid - Look up a filesystem UUID Usage: fsuuid <interface> <dev>:<part> - print filesystem UUID fsuuid <interface> <dev>:<part> <varname> - set environment variable to filesystem UUID => fsuuid mmc 0:1 d9f9fc05-45ae-4a36-a616-fccce0e4f887 => fsuuid mmc 0:2 eb3db83c-7b28-499f-95ce-9e0bb21cda81 => fsuuid mmc 0:1 uuid1 => fsuuid mmc 0:2 uuid2 => printenv uuid1 uuid1=d9f9fc05-45ae-4a36-a616-fccce0e4f887 => printenv uuid2 uuid2=eb3db83c-7b28-499f-95ce-9e0bb21cda81 => Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com> Acked-by: Stephen Warren <swarren@nvidia.com>
* linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada2014-11-23-8/+7
| | | | | | | | | | | | | | | | | | | | U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings. We have two options: - Use min, max, min3, max3 only when the arguments have the same type (or add casts to the arguments) - Use min_t/max_t instead with the appropriate type for the first argument Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Pavel Machek <pavel@denx.de> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini <trini@ti.com>
* include: move various macros to include/linux/kernel.hMasahiro Yamada2014-11-20-4/+0
| | | | | | | | | | | | | | | | | | | | | | | U-Boot has imported various utility macros from Linux scattering them to various places without consistency. In include/common.h are min, max, min3, max3, ARRAY_SIZE, ALIGN, container_of, DIV_ROUND_UP, etc. In include/linux/compat.h are min_t, max_t, round_up, round_down, etc. We also have duplicated defines of min_t in some *.c files. Moreover, we are suffering from too cluttered include/common.h. This commit moves various macros that originate in include/linux/kernel.h of Linux to their original position. Note: This commit simply moves the macros; the macros roundup, min, max, min2, max3, ARRAY_SIZE are different from those of Linux at this point.

* ZFS: Clean up cppcheck warnings where relevant, leaked memory etcJorgen Lundman2014-11-10-1/+8
| | | | | | | | | | | | | | | | | | | | | In a message from Wolfgang Denk highlighting warnings from cppcheck, the patch will address those that are correctly diagnosed. Some are false-positives: > [fs/zfs/zfs.c:937]: (error) Memory leak: l dmu_read() allocates "l" if successful, so error-case should not free it. > [fs/zfs/zfs.c:1141]: (error) Memory leak: dnbuf dmu_read() allocates "dnbuf" if successful, so error-case should not free it. > [fs/zfs/zfs.c:1372]: (error) Memory leak: osp zio_read() allocates "osp" if successful, so error-case should not free it. > [fs/zfs/zfs.c:1726]: (error) Memory leak: nvlist int_zfs_fetch_nvlist() allocates "nvlist" if successful, so error-case should not free it.
