3272 5810 d 17 h jermar /trunk/uspace/srv/fs/fat/ Several fixes for the FAT file system:
- do not copy padding during file name canonization
- properly nul-terminate the FAT file name during canonization
- compare FAT file name and the component name case insensitively
- block_get() takes a block offset, not byte offset as parameter
 
3257 5811 d 17 h jermar /trunk/uspace/srv/fs/fat/ First attempt at delivering the FAT16 read-only support.
Needless to say it doesn't work yet, but now it's only
the lurking bugs that need to be fixed.
 
3253 5813 d 5 h jermar /trunk/uspace/srv/fs/fat/ Pass block size to block_get() in the last argument.  
3201 5848 d 13 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3119 5874 d 12 h jermar /trunk/uspace/srv/fs/fat/ Initialize in-core FAT root directory node during mount.  
3111 5875 d 6 h jermar /trunk/uspace/srv/fs/fat/ Put a frequently used construct into a function.  
3110 5875 d 6 h jermar /trunk/uspace/srv/fs/fat/ Initialize global FAT IDX structures when the FAT server starts and initialize
per-file system FAT IDX structures when a file system gets mounted.
 
2953 5895 d 6 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5895 d 7 h jermar /trunk/uspace/srv/fs/fat/ Add locks to FAT index structures, FAT in-core node structures. Add futex to
protect the list of free cached FAT in-core nodes. Make fat_node_get() and
fat_node_put() and some other functions aware of these new locks.
 
2945 5896 d 5 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5896 d 6 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 5900 d 10 h jermar /trunk/uspace/srv/fs/fat/ Implement fat_node_put() and remove the node from the free node list when
bumping its refernce count from zero in fat_node_get().
 
2893 5901 d 15 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.
 
2891 5904 d 5 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5904 d 7 h jermar /trunk/uspace/srv/fs/fat/ Need a way to locate the FAT index structure by VFS index. Also fix code that
locates the FAT index structure by position in the file system namespace.
 
2889 5907 d 6 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5908 d 6 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5908 d 10 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5908 d 14 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5922 d 4 h jermar /trunk/uspace/srv/fs/fat/ Introduce the foundation for unique and stable FAT VFS node indices.

The first two reserved FAT entries are physically present in each FAT, so fix
the code to be aware of this.
 
2863 5922 d 15 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.
 
2859 5927 d 21 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5927 d 23 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.
 
2857 5928 d 0 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5928 d 0 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5928 d 1 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5928 d 22 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
 
2845 5930 d 4 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5930 d 4 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5930 d 5 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5932 d 22 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5934 d 2 h jermar /trunk/uspace/srv/fs/fat/ BPS read from FAT bootsector is little-endian. It must converted to host
endianity before being used.
 
2822 5935 d 1 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.
 
2798 5939 d 6 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5940 d 6 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5940 d 7 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2789 5945 d 18 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2731 5985 d 13 h jermar /trunk/uspace/srv/ Add the VFS_FREE operation. This operation frees up whatever resources used by
a file system node for which there is no name (i.e. an unlinked node).

Cleanup VFS operations enums and remove unneeded VFS operations.
 
2690 6025 d 5 h jermar /trunk/uspace/srv/ Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.
 
2644 6048 d 9 h jermar /trunk/uspace/ Move incomplete fs interface from fat.h to libfs.
