@ Fix umount() pathname calculation. |
| 2447 |
|
|
| 2448 |
|
"mount --bind /path/to/file1 /path/to/file2" is legal. |
| 2449 |
|
Therefore, "umount /path/to/file2" is also legal. |
| 2450 |
|
Do not automatically append trailing '/' if pathname to be unmounted |
| 2451 |
|
does not end with '/'. |

@ Add preserve KABI compatibility option. (2.6 kernels only) |
| 2454 |
|
|
| 2455 |
|
TOMOYO needs "struct ccs_domain_info *" and "u32" for each |
| 2456 |
|
"struct task_struct". But embedding these variables into |
| 2457 |
|
"struct task_struct" breaks KABI for prebuilt kernel modules (which |
| 2458 |
|
means that you will need to rebuild prebuilt kernel modules). |
| 2459 |
|
|
| 2460 |
|
Since KABI is commonly used (compared to 5 years ago), asking users to |
| 2461 |
|
rebuild kernel modules which are not included in kernel package is no |
| 2462 |
|
longer preferable. Therefore, I added a new option that keeps |
| 2463 |
|
"struct task_struct" unmodified in order to keep KABI. |
| 2464 |
|
|
| 2465 |
|
Note that you have to use ccs-patch-2.6.\*.diff which patches |
| 2466 |
|
kernel/fork.c in order to use this option. Otherwise, TOMOYO will leak |
| 2467 |
|
memory whenever "struct task_struct" is released. |

Regarding "network inet stream accept", "network inet dgram recv", |

"network inet raw recv" directives, I modified to wait for next |
|

connection/datagram if current connection/datagram was discarded. |
|
|
LSM hooks for these directives are currently missing because this |
|
|
behavior may break applications. If you found applications broken by |

|
this behavior, you can set CONFIG::network::inet_stream_accept and/or |
|
|
CONFIG::network::inet_dgram_recv and/or CONFIG::network::inet_raw_recv |

to mode=disabled in order to only disable filtering for incoming |

|
|

I removed "file_pattern" keyword because it is impossible to predefine |

|
all possible pathname patterns. Also, learning pathnames using incomplete |
| 2594 |
|
patterns makes it difficult to later replace using "path_group" keyword. |

| 2597 |

Since it is noisy if a lot of policy violation messages are printed, |
| 2599 |
|
I removed printk(). To be able to check whether policy violation occurred |
| 2600 |
|
or not, I introduced /proc/ccs/stat interface which counts number of |
| 2601 |
|
policy violations occurred. You can firstly check /proc/ccs/stat and then |

check /proc/ccs/reject_log . |

@ Change profile structure. |
|
|
|
|
|
To make it clear that preferences can be specified by per-profile basis, |
|
|
I removed global preference ("PREFERENCE::"). Now, you need to explicitly |
|
|
specify per-profile preference ("$profilenumber-PREFERENCE::"). |
|
|
|
|
|
I changed default mode for access grant logs from "yes" to "no". |
|
|
You may change mode to "yes" if you want all grant logs to be generated. |
|
|
You may override mode using "if audit=yes" if you want specific grant |
|
|
logs to be generated. |
|
|
|
|
|
Since printing all warning/error messages to console is noisy, |
|
|
I changed verbose mode control from per-preference basis to |
|
|
per-functionality basis. Now, you can selectively print warning/error |
|
|
messages. |
