* fat: Fix for invalid cluster sizesSebastian Huber2016-05-201-1/+3
| | | | | | | A cluster size > 32KiB resulted in an infinite loop in fat_init_volume_info() due to an integer overflow. Close #2717.
* dosfs/fat.c: Remove use of register keywordJoel Sherrill2014-02-031-1/+1

* dosfs: Use unprotected chain operationsSebastian Huber2013-08-211-2/+2
| | | | This area is protected by the FAT file system instance lock.

* dosfs: Avoid error caused by bdbuf configurationSebastian Huber2012-12-141-10/+5
| | | | | | The success of a block size change depends on the bdbuf configuration. Do not treat a failed block size change as a hard error. This is only a missed performance optimization.
* dosfs: Cluster write optimizationRalf Kirchner2012-12-051-56/+184
| | | | | | Separate cluster write from sector write for quick file write. New test fstests/fsdosfswrite01.
* dosfs: Block size optimizationRalf Kirchner2012-12-051-94/+108
| | | | | | Change block size of bdbuf to the cluster size if the data clusters are aligned on a cluster boundary. This enables fast access to data clusters.
* dosfs: Lazy update of FAT32 FS info sectorSebastian Huber2012-11-131-64/+77
| | | | | | | | | | | | | | | | | | | | | The FAT32 FS info sector contains hints for the free cluster count and the next free cluster. The previous code read these values during mount and replaced them with invalid values. The shutdown operation updated them with the current values. These values are only hints. Every FAT implementation must cope with arbitrary values. They are intended to speed up certain operations. Now we update the free cluster count and next free culster in the FAT32 FS info sector only during unmount or sync operations and only if the values have changed. This avoids writes to the FS info sector and conforms to the behaviour of Linux and Windows. The application can force an update of these values now with the fsync() and fdatasync() operations. Applications that only read will perform not write operations to the FAT32 FS info sector. The new fat_sync() function performs all non-file specific synchronizations.
* dosfs: Use FAT_UNDEFINED_VALUESebastian Huber2012-11-131-4/+4

* dosfs: Use fs_info instead of mt_entrySebastian Huber2012-07-111-57/+42

* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-111-2/+0
| | | | | | | | | | | | Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.
* Filesystem: PR1893: Fix write and truncate handlerSebastian Huber2012-05-111-0/+36
| | | | | Space that grows due to truncate or write offsets beyond the current file size must be zero filled.
* libblock: Change bdbuf APISebastian Huber2012-03-131-32/+44
| | | | | | | | | | | | | | | | | | | | The functions o rtems_bdbuf_get(), o rtems_bdbuf_read(), o rtems_bdbuf_syncdev(), and o rtems_bdbuf_purge_dev(), use now the disk device instead of the device identifier. This makes bdbuf independent of rtems_disk_obtain() and rtems_disk_release(). It is the responsiblity of the file system to obtain the disk device. This also reduces the overhead to get a buffer. The key for the AVL tree uses now the disk device instead of the device identifier. The pointer is interpreted as an unsigned integer. This reduces the memory overhead and makes the comparison operation a bit faster. Removed function rtems_bdbuf_purge_major(). This function was too destructive and could have unpredictable side effects.
