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). |

Finish implementation of readdir(). Functions from this family are implemented
via using file descriptors for directories. For example, readdir() is
implemented as read() from an open directory. Of course, FS implementations
must understand that they are asked to read a directory and behave accordingly. |
|

6014 d 5 h |

/trunk/uspace/lib/libc/ |
Add opendir(), rewinddir(), closedir() and some prototypes and stubs. Add dirent.h. |
|
| 2693 |
6014 d 12 h |
jermar |
/trunk/uspace/ |
Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS. |
|
| 2688 |
6019 d 4 h |

/trunk/uspace/ |
Make uspace rwlock API naming conventions consistent with kernel rwlock API. |
|
| 2684 |
6021 d 5 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). |
|
| 2682 |
6021 d 11 h |

/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 |
6021 d 12 h |

/trunk/uspace/ |
Turn the namespace futex into rwlock. |
|
| 2680 |
6021 d 12 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. |

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 |
6027 d 8 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. |
|

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. |
|
| 2675 |

Actually use the nbyte argument in both read() and write().
Fix warnings in read() and write(). |
|
| 2674 |
6028 d 4 h |
jermar |
/trunk/uspace/ |
Add libc VFS wrapper for VFS_WRITE. Fix a small bug in read(). Place open(),
read() and write() declarations in their respective headers according to SUSv3. |
|
| 2671 |
6028 d 4 h |
jermar |
/trunk/uspace/lib/libc/ |
Add VFS wrappers for VFS_MOUNT, VFS_OPEN and VFS_READ to libc. |
|

/trunk/uspace/ |
Move the open(), read() and write() provided by streams.c away so that
these functions won't clash with the real open(), read() and write(), which are
soon to be provided by a libvfs library. Applications can now use open_stdin(),
open_stdout(), read_stdin() and write_stdout(). Later, there might be an option
of providing a custom console file system, which will work similarly to how
streams' open(), read() and write() worked. |

Reimplement VFS_READ using IPC_M_DATA_READ. |
|
| 2662 |
6035 d 4 h |
jermar |
/trunk/ |
Add support for IPC_M_DATA_READ calls. |
|
| 2660 |
6035 d 5 h |
jermar |
/trunk/ |
Rename IPC_M_DATA_SEND to IPC_M_DATA_WRITE. Now, when we also add
IPC_M_DATA_READ, it will not clash and cause confusion with userspace wrappers
such as ipc_data_receive(). Rename the forementioned wrappers to
ipc_data_write_send(), ipc_data_write_receive() and ipc_data_write_deliver(). |

VFS work.
Move FS registration code to libfs. |
|

Start libfs.
libfs is to contain all common fs code. |

Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test. |
|

Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves. |

Modify the async framework to make use of all six syscall arguments.
Supply user-friendly macros as in previous cases. |
|

/trunk/ |
Be more deterministic when a user accidently uses fast version of IPC
call/answer instead of the full one and passes fewer arguments than required by
the recipient of the call/response.
and the recipient interprets arguments that
were actually not passed by the sender. |
|

Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer(). |
|
| 2618 |
6068 d 16 h |
jermar |
/trunk/ |
Modify asynchronous IPC to make use of all six syscall arguments. The preferred
means of asynchronous communication is now via the set of ipc_call_async_m()
macros, where m is the number of payload arguments passed to the kernel. These
macros will automatically decide between the fast and the universal slow version
of ipc_call_async. |
|

usleep() should return int. Non-void functions really should return a value, so
fix sleep() to always return 0. |
|
| 2615 |
6069 d 13 h |
jermar |
/trunk/ |
Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync. |

Support for six syscall arguments for sparc64.
There is a minor stability issue which needs to be fixed (kernel panics upon entering kconsole from the
console task). |
