3397 5823 d 3 h rimsky /branches/sparc/ Merged recent changes from trunk into the Sparc branch.  
3343 5847 d 0 h decky /branches/sparc/ add sparc branch  
3255 5857 d 7 h jermar /trunk/uspace/ Fix the VFS protocol so that the client can determine that VFS_MOUNT failed due
to a request to mount an unregistered file system.		  
3215 5890 d 4 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3201 5894 d 3 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5921 d 1 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.		  
3079 5924 d 2 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5939 d 19 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5939 d 20 h jermar /trunk/uspace/srv/vfs/ Cram VFS_MOUNT into one message. This creates a hidden demand for the sixth IPC
argument as there might be a desire to pass some options/flags in the future.		  
2821 5980 d 15 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2788 5991 d 9 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 6007 d 20 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 6008 d 19 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 6008 d 21 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 6009 d 21 h jermar /trunk/uspace/srv/vfs/ Grab the nodes_futex when manipulating node link counts in rename() and
_unlink().

Fix VFS futex definitions and declarations by replacing atomic_t by futex_t.		  
2763 6009 d 23 h jermar /trunk/uspace/ Support for rename().  
2753 6016 d 19 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 6017 d 2 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 6018 d 0 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 6019 d 19 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 6019 d 19 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 6022 d 18 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().		  
2740 6028 d 19 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2735 6031 d 0 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6031 d 2 h jermar /trunk/uspace/ Support for close().  
2731 6031 d 3 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 6032 d 5 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2710 6051 d 22 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 6052 d 0 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 6052 d 0 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6052 d 2 h jermar /trunk/uspace/ Support for mkdir().  
2704 6053 d 5 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 6060 d 3 h jermar /trunk/uspace/ Introduce the notion of lflag (i.e. lookup flags) to support the ability to
limit the scope of VFS node types that can be opened by open() and opendir(). In
the future, lflag will also specify actions for VFS_LOOKUP handlers that will be
carried out in situations such as the VFS node is not found (e.g. implementation
of mkdir() and open() with O_CREAT in oflag).		  
2698 6060 d 23 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.		  
2693 6066 d 3 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 6069 d 21 h jermar /trunk/uspace/srv/vfs/ Improve the API for converting (VFS triplets, size) to VFS nodes by introducing
a new type for results of vfs_lookup_internal().		  
2690 6070 d 19 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.		  
2689 6070 d 20 h jermar /trunk/uspace/srv/vfs/ Merge all VFS operations into one file.  
2688 6070 d 20 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2687 6070 d 20 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.
