3386 5907 d 5 h decky /branches/network/ add new network branch (copy of current trunk)  
3352 5919 d 1 h jermar /trunk/uspace/srv/ Add reference to the mounted FS root.

This makes it possible to keep the FS root logically unlinked (i.e. lnkcnt == 0)
because it prevents VFS from attempting to destroy it during closedir().		  
3335 5923 d 0 h jermar /trunk/uspace/srv/fs/fat/ Support for readdir() on FAT.  
3325 5926 d 1 h jermar /trunk/uspace/srv/fs/fat/ Determine the size of a directory node by walking the FAT and counting clusters.
This eliminates the hardcoded limit on the number of directory entries.		  
3314 5927 d 2 h jermar /trunk/uspace/srv/fs/fat/ fat_read() should expect IPC_M_DATA_READ instead of IPC_M_DATA_WRITE.  
3312 5927 d 2 h jermar /trunk/uspace/srv/fs/fat/ When removing a FAT node from the ffn list, use the correct pointer instead of
an uninitialized one.		  
3308 5929 d 0 h jermar /trunk/uspace/srv/fs/fat/ More complete fat_read().  
3307 5929 d 2 h jermar /trunk/uspace/srv/fs/fat/ Dummy implementation of fat_read().  
3282 5930 d 23 h jermar /trunk/uspace/srv/fs/fat/ FAT dentry type used for subdirectories doesn't store the directory size in the 'size' field.
Introduce a simple workaround that will let us have 64 directory entries at maximum.		  
3272 5931 d 12 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 5932 d 11 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 5934 d 0 h jermar /trunk/uspace/srv/fs/fat/ Pass block size to block_get() in the last argument.  
3201 5969 d 8 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3119 5995 d 6 h jermar /trunk/uspace/srv/fs/fat/ Initialize in-core FAT root directory node during mount.  
3111 5996 d 0 h jermar /trunk/uspace/srv/fs/fat/ Put a frequently used construct into a function.  
3110 5996 d 1 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 6016 d 0 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 6016 d 1 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 6017 d 0 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 6017 d 0 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 6021 d 5 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 6022 d 10 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 6025 d 0 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 6025 d 2 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 6028 d 1 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 6029 d 0 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 6029 d 5 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 6029 d 9 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 6042 d 23 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 6043 d 10 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 6048 d 15 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 6048 d 18 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 6048 d 18 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 6048 d 18 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 6048 d 19 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 6049 d 16 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 6050 d 22 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 6050 d 23 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 6051 d 0 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 6053 d 16 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.
