Introduce the open file lock. Modify vfs_rdwr() to take this lock into account
when reading or writing from/to an open file. |
|

/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. |
|

Turn the namespace futex into rwlock. |
|

6032 d 8 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. |

Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients. |

/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. |
|

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. |

Rename variable from 'size' to 'len'. |

The previous commit was not entirely sane.
Handle VFS_WRITE correctly when the file doesn't grow.
Handle it correctly also when the file grows. |

VFS and TMPFS support for VFS_WRITE. |

/trunk/uspace/srv/fs/tmpfs/ |
Fix two bugs in TMPFS-side VFS_READ. |
|
| 2663 |
6045 d 23 h |

/trunk/uspace/ |
Reimplement VFS_READ using IPC_M_DATA_READ. |
|
| 2660 |
6046 d 1 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(). |

Start TMPFS.
Not loaded during boot as there is a reproducible kernel panic which occurs when
both tmpfs and fat are loaded. |

VFS work.
During VFS_REGISTER, use strncmp() instead of strcmp().
Add one excessive convenience byte to vfs_info.name to support the
above-mentioned change. In case the fs name spans all available
characters, make sure this convenience byte is zero. |

Function ipc_connect_me_to sends 3 user defined arguments now.

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/ |
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 |
6079 d 11 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. |
