3009 5858 d 1 h svoboda /branches/dynload/ Merged latest trunk changes into dynload  
2927 5869 d 12 h decky /branches/dynload/ added dynload branch  
2821 5906 d 21 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2788 5917 d 14 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)
 
2770 5934 d 1 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5935 d 0 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5935 d 2 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5936 d 2 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 5936 d 5 h jermar /trunk/uspace/ Support for rename().  
2753 5943 d 1 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5943 d 7 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5944 d 5 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.
 
2749 5946 d 0 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5946 d 1 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 5949 d 0 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 5955 d 0 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2735 5957 d 6 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5957 d 7 h jermar /trunk/uspace/ Support for close().  
2731 5957 d 8 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 5958 d 11 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2710 5978 d 3 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 5978 d 5 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 5978 d 6 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 5978 d 7 h jermar /trunk/uspace/ Support for mkdir().  
2704 5979 d 10 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 5986 d 8 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 5987 d 4 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
 
2693 5992 d 9 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 5996 d 2 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 5997 d 0 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 5997 d 1 h jermar /trunk/uspace/srv/vfs/ Merge all VFS operations into one file.  
2688 5997 d 1 h jermar /trunk/uspace/ Make uspace rwlock API naming conventions consistent with kernel rwlock API.  
2687 5997 d 1 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2684 5999 d 2 h jermar /trunk/ Add libc and VFS implementation of lseek(), VFS_SEEK resp.
Add the size member to the VFS node structure (not yet initialized).
 
2683 5999 d 5 h jermar /trunk/uspace/srv/vfs/ Introduce the open file lock. Modify vfs_rdwr() to take this lock into account
when reading or writing from/to an open file.
 
2682 5999 d 8 h jermar /trunk/uspace/ Fix type in declaration of VFS node rwlock.
Introduce a dedicated type for futexes. Make the existing futex code use this
newly introduced type and fix formatting in futex.c.
 
2681 5999 d 9 h jermar /trunk/uspace/ Turn the namespace futex into rwlock.  
2680 5999 d 9 h jermar /trunk/uspace/ Add basic rwlock API for uspace so that VFS can be designed/implemented using
this API. So far, the implementation of this API merely wraps futexes into
rwlocks. Real rwlocks are wanted by ticket #54.

Using the new rwlock API, replace the VFS node content futex with an rwlock.
Lock the contents rwlock as reader on reads and as writer on writes.
 
2679 6003 d 2 h jermar /trunk/uspace/srv/vfs/ Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients.
 
2678 6005 d 5 h jermar /trunk/uspace/ The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send,
receive and deliver wrappers to names ending with 'start', 'receive' and
'finalize', respectively. This should make it clearer for dummies.
