4370 5560 d 8 h jermar /trunk/uspace/ Streamline TMPFS and fix its design so that it properly supports hardlinks.
libfs operation unlink() is now passed also the name of the component being
unlinked.
 
4357 5564 d 8 h jermar /trunk/uspace/ Introduce the concept of FS nodes. A FS node is a typed abstraction of
file-system-specific node type. It replaces the void * in libfs interfaces
and is suitable for holding various information such as mount point data.
 
4306 5581 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Support multiple TMPFS instances.  
4305 5581 d 15 h jermar /trunk/uspace/ Support mount options.
Let tmpfs decide whether to start empty or restored a TMPFS dump based on the mount option.
 
4268 5589 d 22 h svoboda /trunk/uspace/ str_cpy() and str_ncpy() in userspace. Nuke strcpy() and strncpy().  
4264 5590 d 9 h svoboda /trunk/uspace/ Nuke strcpy() and strcmp().  
3625 5727 d 18 h jermar /trunk/uspace/ libfs operation link() should return standard error code instead of mere
true/false.
 
3575 5741 d 9 h jermar /trunk/uspace/ libfs create operation should take the device handle as argument.  
3352 5820 d 11 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().
 
3109 5897 d 15 h jermar /trunk/uspace/srv/ Split the 'mount another filesystem here' and 'you are being mounted and the
device is this' mount semantics. Add VFS_MOUNTED VFS operation that corresponds
to the latter and reserve VFS_MOUNT only for the former. Because of this
change, the VFS server does not maintain the mr_node VFS node for the name space
root anymore and the VFS_LOOKUP operation is now not meant to be used on
unmounted file system, not even for looking up the root node of unmounted file
systems. In the light of these changes, TMPFS is now initialized from
tmpfs_mounted() function.
 
3103 5898 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Evict the code which loads the TMPFS file system from a file system dump to a
dedicated source file.
 
3091 5900 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Return value argument to ipc_call_sync_X_Y() may not be int or it will
break on 64-machines that are sensitive to unaligned memory accesses.
Moreover, overcasting int * to sysarg_t * is not a good idea either
even if the int is by chance aligned on a 64-bit boundary as some
unknown memory will get overwritten during the assignment. Change the
type of the retval argument to ipcarg_t.
 
3087 5900 d 15 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk  
2958 5916 d 8 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2863 5944 d 19 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.
 
2858 5950 d 3 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.
 
2857 5950 d 3 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2852 5951 d 1 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.
 
2844 5952 d 8 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2831 5955 d 1 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2792 5962 d 11 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5965 d 8 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2770 5984 d 10 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 5986 d 13 h jermar /trunk/uspace/ Support for rename().  
2760 5989 d 8 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5990 d 8 h jermar /trunk/uspace/ No need to keep the parent pointer in the TMPFS node. Moreover, other file
systems won't have it either. Finally, if TMPFS is to support hardlinks, there
can be multiple parents.
 
2757 5990 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5990 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 5997 d 7 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5999 d 8 h jermar /trunk/uspace/srv/ Separate creation of a TMPFS node and its linking in the file system name space.
Rename VFS_FREE to VFS_DESTROY and destroy_node() to unlink_node().
 
2739 6005 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6007 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6007 d 14 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 6007 d 16 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6007 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6007 d 17 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.
 
2730 6008 d 19 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6013 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6028 d 11 h jermar /trunk/uspace/ Remove the debugging hack from tmpfs_init(), which created several files and
directories on the filesystem. TMPFS is now self-sufficient enough to be able
to create its content via the standard VFS interface.
 
2710 6028 d 11 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.
