Make VFS_MOUNT call even when mounting the root file system.
2957
5933 d 11 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.

Update comment.

Return EBUSY if trying to mount something over an already mounted root FS.

6001 d 11 h
jermar
/trunk/uspace/
Introduce fs_handle_t, dev_handle_t and fs_index_t.
2769
6002 d 9 h
jermar
/trunk/uspace/srv/vfs/
VFS index needs to be treated as uint64_t.
2768
6002 d 11 h
jermar
/trunk/uspace/srv/vfs/
Fibril serialization is required when two file systems register contemporarily.
2766
6003 d 11 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
6003 d 14 h
jermar
/trunk/uspace/
Support for rename().
2753
6010 d 10 h
jermar
/trunk/uspace/
Move canonify() to libc so that it can be used also on the libc side.
2752
6010 d 16 h
jermar
/trunk/uspace/srv/vfs/
Make VFS canonify path names on lookup.
2751
6011 d 14 h
jermar
/trunk/uspace/
Add canonify() for file system path canonization.
Not yet used by VFS.
2749
6013 d 10 h
jermar
/trunk/uspace/srv/vfs/
contents_rwlock should not be acquired as a futex but rather as a rwlock.
2748
6013 d 10 h
jermar
/trunk/uspace/srv/vfs/
Support for O_TRUNC.
2742
6016 d 9 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
6022 d 9 h
jermar
/trunk/uspace/srv/vfs/
Initialize the VFS node properly.
2735
6024 d 15 h
jermar
/trunk/uspace/
Support for rmdir(), unlink() and the respective VFS operations.
2734
6024 d 16 h
jermar
/trunk/uspace/
Support for close().
2731
6024 d 18 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
6025 d 20 h
jermar
/trunk/uspace/srv/
Introduce the notion of VFS node link counts.
2710
6045 d 12 h
jermar
/trunk/uspace/
VFS_WRITE and tmpfs_write fixes.
2709
6045 d 14 h
jermar
/trunk/uspace/srv/vfs/
VFS_OPEN and VFS_WRITE now understand O_APPEND.
2708
6045 d 15 h
jermar
/trunk/uspace/
VFS_OPEN now understands O_CREAT and O_EXCL.
2707
6045 d 16 h
jermar
/trunk/uspace/
Support for mkdir().
2704
6046 d 19 h
jermar
/trunk/uspace/srv/vfs/
Additional VFS lookup flags.
2700
6053 d 18 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
6054 d 13 h
jermar
/trunk/uspace/srv/vfs/
Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
2693
6059 d 18 h
jermar
/trunk/uspace/
Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.
2691
6063 d 11 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
6064 d 9 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
6064 d 10 h
jermar
/trunk/uspace/srv/vfs/
Merge all VFS operations into one file.
2688
6064 d 10 h
jermar
/trunk/uspace/
Make uspace rwlock API naming conventions consistent with kernel rwlock API.
2687
6064 d 11 h
jermar
/trunk/uspace/srv/
Management of the cached VFS node size.
2684
6066 d 12 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
6066 d 15 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
6066 d 17 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
6066 d 18 h
jermar
/trunk/uspace/
Turn the namespace futex into rwlock.
2680
6066 d 18 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.
