6053 d 1 h
jermar
/trunk/uspace/
Support for mkdir().
2704
6054 d 3 h
jermar
/trunk/uspace/srv/vfs/
Additional VFS lookup flags.
2700
6061 d 2 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
6061 d 22 h
jermar
/trunk/uspace/srv/vfs/
Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
2693
6067 d 2 h
jermar
/trunk/uspace/
Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.
2691
6070 d 20 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
6071 d 18 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
6071 d 19 h
jermar
/trunk/uspace/srv/vfs/
Merge all VFS operations into one file.
2688
6071 d 19 h
jermar
/trunk/uspace/
Make uspace rwlock API naming conventions consistent with kernel rwlock API.
2687
6071 d 19 h
jermar
/trunk/uspace/srv/
Management of the cached VFS node size.
2684
6073 d 20 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
6073 d 23 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
6074 d 2 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
6074 d 2 h
jermar
/trunk/uspace/
Turn the namespace futex into rwlock.
2680
6074 d 3 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
6077 d 19 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
6079 d 22 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.
2677
6079 d 23 h
jermar
/trunk/
Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.
2676
6080 d 5 h
jermar
/trunk/
Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.
2666
6085 d 20 h
jermar
/trunk/uspace/srv/
VFS and TMPFS support for VFS_WRITE.
