* IMFS: Improved support for generic nodesSebastian Huber2014-01-212-3/+3
| | | | | | | | | | | | | | | | The rtems_filesystem_location_info_t::node_access_2 was unused by the IMFS. Use it to hold the context of generic nodes. This makes it possible to use node handlers for objects with and without a corresponding file system node. For example network sockets created with socket() have only a file descriptor, but no corresponding file system node. The UNIX(4) domain sockets can be bound to file system nodes. In both cases the rtems_filesystem_location_info_t must provide a pointer to the socket structure used by the socket node handlers. With the context pointer (for sockets, this is the socket structure) in rtems_filesystem_location_info_t::node_access_2 the same node handlers can be used in both cases.

* Filesystem: Add readv/writev handlersSebastian Huber2013-12-2018-89/+249
| | | | | | | | | The readv() and writev() support was implemented in terms of multiple calls to the read and write handlers. This imposes a problem on device files which use an IO vector as single request entity. For example a low-level network device (e.g. BPF(4)) may use an IO vector to create one frame from multiple protocol layers each with its own IO vector entry.
* For PR 2164 - RFS File System - fix bitmap_create_search loop bugAlan Cudmore2013-12-191-1/+2
| | | | | | | | | | | | | | | | | This is for the RFS file system. There is a bug in the rtems_rfs_bitmap_create_search loop. It is supposed to iterate over the range of bits in a search element ( usually 32 bits ), so it should loop through bits 0 through 31. Instead it loops through 0 - 32, causing some blocks not to be allocated. As in PR 2163, this depends on the block size and number of blocks in a file system. Block sizes and group sizes that are powers of 2 seem to work fine ( 512 byte blocks, 4096 block groups, etc ). When the block sizes are not powers of 2, then this loop error causes some of the blocks at the end of a group to be skipped, preventing 100% of the blocks from being used. A simple test for this and PR2163 is to create a RAM disk with block size 3900 and at least 1 full group ( 31200 blocks ). A file system with these sizes will not be able to allocate 100% of the blocks.
* For PR 2162 - RFS File System - statvfs reports 1 block freeAlan Cudmore2013-12-192-2/+2
| | | | | | | | | This is for the RFS file system. The statvfs call reports 1 block free when the file system is full because it does not account for the superblock in its calculation of free blocks. This is a simple fix that adjusts the number of blocks reported to account for the superblock. We may want to wait for a more complete solution such as locating the superblock in each group.
* For PR 2163 - RFS File System - fix group search algorithm bugAlan Cudmore2013-12-191-1/+15
| | | | | | | | | This is for the RFS file system. There is a bug in the group search algorithm where it will skip groups, causing blocks to remain unallocated. This is dependant on the size of the blocks and number of blocks in a group, so it does not always show up. The fix corrects the skipping of groups during the search, allowing all of the blocks to be found.

* IMFS: Fix truncate according to POSIXSebastian Huber2013-09-131-3/+2
| | | | | | | | | | | | | | | | | ftruncate() and open() with O_TRUNC shall upon successful completion mark for update the st_ctime and st_mtime fields of the file. truncate() shall upon successful completion, if the file size is changed, mark for update the st_ctime and st_mtime fields of the file. The POSIX standard "The Open Group Base Specifications Issue 7", IEEE Std 1003.1, 2013 Edition says nothing about the behaviour of truncate() if the file size remains unchanged. Future directions of the standard may mandate the behaviour specified in ftruncate(): http://austingroupbugs.net/view.php?id=489
