4586 5444 d 9 h jermar /trunk/uspace/ Add libfs_stat() and let FAT and TMPFS use it.  
4585 5444 d 10 h jermar /trunk/uspace/ Introduce VFS_IN_FSTAT and VFS_OUT_STAT.
Provide libc fstat() and devfs_stat().
This functionality replaces VFS_IN_NODE
and VFS_IN/OUT_DEVICE. FAT and TMPFS
still do not implement this and VFS_IN_STAT
and stat() need implementation as well.		  
4509 5464 d 15 h decky /trunk/uspace/ rename libadt -> adt  
4465 5469 d 10 h decky /trunk/uspace/srv/fs/ implement VFS_OPEN_NODE and VFS_DEVICE (no device handle is returned)
implement no-op VFS_SYNC and VFS_CLOSE		  
4429 5481 d 9 h jermar /trunk/uspace/ Add fs_handle argument to libfs_mount() needed to recognize homogenous mounts.  
4424 5482 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Call libfs_mount() from tmpfs_mount().  
4409 5484 d 7 h jermar /trunk/uspace/ Rudimentary support for non-root mounts.  
4370 5494 d 7 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 5498 d 7 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 5515 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Support multiple TMPFS instances.  
4305 5515 d 13 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 5523 d 21 h svoboda /trunk/uspace/ str_cpy() and str_ncpy() in userspace. Nuke strcpy() and strncpy().  
4264 5524 d 7 h svoboda /trunk/uspace/ Nuke strcpy() and strcmp().  
3625 5661 d 16 h jermar /trunk/uspace/ libfs operation link() should return standard error code instead of mere
true/false.		  
3575 5675 d 7 h jermar /trunk/uspace/ libfs create operation should take the device handle as argument.  
3352 5754 d 9 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 5831 d 13 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 5832 d 6 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 5834 d 9 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 5834 d 14 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk  
2958 5850 d 7 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2863 5878 d 17 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2858 5884 d 1 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5884 d 2 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2852 5884 d 23 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 5886 d 6 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2831 5889 d 0 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2792 5896 d 9 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5899 d 6 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2770 5918 d 8 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 5920 d 11 h jermar /trunk/uspace/ Support for rename().  
2760 5923 d 6 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5924 d 7 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 5924 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5924 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 5931 d 6 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5933 d 6 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 5939 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5941 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5941 d 12 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.
