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
5845 d 12 h
jermar
/trunk/uspace/srv/fs/fat/
Support for readdir() on FAT.
3325
5848 d 13 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
5849 d 14 h
jermar
/trunk/uspace/srv/fs/fat/
fat_read() should expect IPC_M_DATA_READ instead of IPC_M_DATA_WRITE.
3312
5849 d 14 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
5851 d 13 h
jermar
/trunk/uspace/srv/fs/fat/
More complete fat_read().
3307
5851 d 14 h
jermar
/trunk/uspace/srv/fs/fat/
Dummy implementation of fat_read().

5853 d 11 h

/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.

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

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
5856 d 12 h
jermar
/trunk/uspace/srv/fs/fat/
Pass block size to block_get() in the last argument.
3119
5917 d 19 h
jermar
/trunk/uspace/srv/fs/fat/
Initialize in-core FAT root directory node during mount.
3110
5918 d 13 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
5938 d 12 h
jermar
/trunk/uspace/srv/fs/fat/
Add synchronization to fat_match().
2951
5938 d 13 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.
2910
5943 d 17 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
5944 d 22 h
jermar
/trunk/uspace/srv/fs/fat/
More bits of fat_node_get().
Still needs to do some locking.
2891
5947 d 12 h
jermar
/trunk/uspace/srv/fs/fat/
New first bits of fat_node_get().
2890
5947 d 14 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.
2881
5951 d 17 h
jermar
/trunk/uspace/srv/fs/fat/
Code for de/allocation of VFS indices for FAT.
2876
5951 d 21 h
jermar
/trunk/uspace/srv/fs/fat/
Add a dedicated source file for handling FAT indices.
2864
5965 d 11 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
5965 d 22 h
jermar
/trunk/uspace/
Revert libfs node_get() API to a model without the parent node pointer
argument.
2859
5971 d 3 h
jermar
/trunk/uspace/srv/fs/fat/
Add fat_block_get().
2858
5971 d 6 h
jermar
/trunk/uspace/
libfs destroy operation should rather return an error code instead of a truth
value.
2857
5971 d 6 h
jermar
/trunk/uspace/
Add stubs for unimplemented FAT libfs operations.
2856
5971 d 7 h

Add a locking scheme for FAT in-core cache and nodes.
2855

fat_node_put(). No locking so far.
2852
5972 d 4 h
jermar

Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.

2844
5973 d 11 h
jermar
/trunk/uspace/
Add fat_root_get() and fat_plb_get_char().
2843
5973 d 12 h

Commit progress on the FAT file system server implementation.
2828
5977 d 9 h
jermar

endianity before being used.
