|
@ Return 0 when ccs_may_umount() succeeds. |
| 1502 |
|
|
| 1503 |
|
I forgot to clear error value in ccs_may_umount() when the requested |
| 1504 |
|
directory didn't match "deny_unmount" keyword. As a result, any umount() |
| 1505 |
|
request with RESTRICT_UNMOUNT=enforcing returned -EPERM error. |

@ Fix "Compilation failure" with 2.4.20 kernel. |
| 1512 |
|
|
| 1513 |
|
RedHat Linux 9's 2.4.20 kernel backported O(1) scheduler patch, |
| 1514 |
|
resulting compilation error at ccs_load_policy(). |
| 1515 |
|
I added defined(TASK_DEAD) check. |

|
@ Don't check permissions if vfsmount is NULL. |
| 1520 |
|
|
| 1521 |
|
Some filesystems (e.g. unionfs) pass NULL vfsmount. |
| 1522 |
|
I changed fs/tomoyo_file.c not to try to calculate pathnames |
| 1523 |
|
if vfsmount is NULL. |

|
@ Add workaround for gcc 4.3's bug. |
| 1530 |
|
|
| 1531 |
|
In some environments, fs/tomoyo_network.c could not be compiled |
| 1532 |
|
because of gcc 4.3's bug. |
| 1533 |
|
I modified save_ipv6_address() to use "integer literal" value |
| 1534 |
|
instead for "static const u8" variable. |
| 1535 |
|
|
| 1536 |
|
@ Change prototypes of some functions. |
| 1537 |
|
|
| 1538 |
|
To support 2.6.27 kernels, I replaced "struct nameidata" with |
| 1539 |
|
"struct path" for some functions. |
| 1540 |
|
|
| 1541 |
|
@ Detect distributor specific patches automatically. |
| 1542 |
|
|
| 1543 |
|
Since kernels with AppArmor patch applied is increasing, |
| 1544 |
|
I introduced a mechanism which determines whether specific patches |
| 1545 |
|
are applied or not, based on "#define" directives in the patches. |

@ Remove "-ccs" suffix from Makefile's EXTRAVERSION. |
| 1550 |
|
|
| 1551 |
|
To reduce conflicts on Makefile's EXTRAVERSION, |
| 1552 |
|
I removed "-ccs" suffix from ccs-patch-2.\*.diff . |
| 1553 |
|
Those who build kernels without using specs/build-\*.sh , |
| 1554 |
|
please edit EXTRAVERSION tag manually so that original kernels |
| 1555 |
|
will not be overwritten by TOMOYO Linux kernels. |

|

| 1561 |
|
@ Add "try again" response to "delayed enforcing" mode. |
| 1562 |
|
|
| 1563 |
|
To be able to handle pathname changes caused by software updates, |
| 1564 |
|
"delayed enforcing" mode was introduced. It allows administrator to |
| 1565 |
|
grant access requests which are about to be rejected by the kernel. |
| 1566 |
|
|
| 1567 |
|
To be able to handle pathname changes caused by software updates better, |
| 1568 |
|
I introduced "try again" response. As "delayed enforcing" mode sleeps |
| 1569 |
|
a process which violated policy, administrator can update policy while |
| 1570 |
|
the process is sleeping. This "try again" response allows administrator |
| 1571 |
|
to restart policy checks from the beginning after updating policy. |
| 1572 |
|

|
Fix 2008/09/11 |
| 1574 |
|
|
| 1575 |
|
@ Remember whether the process is allowed to write to /proc/ccs/ interface. |
| 1576 |
|
|
| 1577 |
|
Since programs for manipulating policy (e.g. ccs-queryd ) are installed |
| 1578 |
|
in the form of RPM/DEB packages, these programs lose the original |
| 1579 |
|
pathnames when they are updated by the package manager. The package |
| 1580 |
|
manager renames these programs before deleting these programs so that |
| 1581 |
|
the package manager can rollback the operation. |
| 1582 |
|
This causes a problem when the programs are listed into /proc/ccs/manager |
| 1583 |
|
using pathnames, as the programs will no longer be allowed to write to |
| 1584 |
|
/proc/ccs/ interface while the process of old version of the program is |
| 1585 |
|
alive. |
| 1586 |
|
|
| 1587 |
|
To solve this problem, I modified to remember the fact that the process |
| 1588 |
|
is once allowed to write to /proc/ccs/ interface until the process |
| 1589 |
|
attempts to execute a different program. |
| 1590 |
|
This change makes it impossible to revoke permission to write to |
| 1591 |
|
/proc/ccs/ interface without killing the process, but it will be better |
| 1592 |
|
than nonfunctioning ccs-queryd program. |
