* fs: let truncate take a loff_t argumentSascha Hauer2019-02-061-1/+1
| | | | | | | loff_t is the correct type for file sizes. Use it to allow to truncate to sizes bigger than 32bit. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* fs: devfs: Change .lseek callbacks to return 'int'Andrey Smirnov2019-02-041-2/+2
| | | | | | | | | | | Returning requested offset from .lseek() callback doesn't really give us any new information while bringing unnecessary complications. Change all .lseek() types (both in struct struct cdev_operations and in struct fs_driver_d) to return 'int' and adjust the rest of the codebase accordingly.

* fs: Update FILE position in lseek()Andrey Smirnov2019-01-291-1/+0
| | | | | | | | | | Instead on relying on driver callbacks to update 'pos' in FILE, do it as a part of lseek() code. This allows us to drop a bit of repeating code as well as making lseek() implementation consistent with write() and read().

* fs/fat: fix FAT32 detectionAlexander Kurz2019-01-041-5/+7
| | | | | | | | | | | | Limits for the number of clusters were used to determine the FAT fs type. This fails e.g. for FAT32 fs with low cluster number that can be found in certain Android images. Sync the FAT fs type detection to the method used in linux by checking the sectors/FAT entries at offset 0x16 (must be zero for FAT32) and offset 0x24 (must be non-zero for FAT32).

* fs: dentry cache implementationSascha Hauer2018-07-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | This adds the Linux dentry cache implementation to barebox. Until now every filesystem driver resolves the full path to a file for itself. This leads to code duplication and is error prone since resolving paths is a complicated task. Also it can narrow down the lookup performance since barebox only knows ASCII paths and has no way of caching lookups. With this patch we get the Linux dcache implementation. The path resolving code from fs/namei.c is nearly taken as-is, minus the RCU and locking code. Dcaching is made simple as of now: We simply cache everything and never release any dentries. Although we do reference counting for inodes and dentries it is effectively not used yet. We never free anything until a fs is unmounted in which case we free everything no matter if references are taken or not. This patch also contains a wrapper in fs/legacy.c to support filesystems with the old API. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* fs: cleanup backingstore handlingSascha Hauer2013-09-291-13/+4
| | | | | | | | | | | All filesystem drivers which need a backingstore device do the same ignoring of '/dev/' in the backingstore followed by a cdev_open. Add a helper function for it and let the core handle the cdev. As a side effect this makes sure that fsdev->cdev is also set when a device is mounted without the leading '/dev/' which was previously ignored by the mount code.

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-011-8/+7
| | | | | | | | | | | | | | | | | | | | | Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.
