@ Fix incomplete read after seek. |
| 2987 |
|
|
| 2988 |
|
ccs_flush() tries to flush data to be read as soon as possible. |
| 2989 |
|
ccs_select_domain() (which is called by write()) enqueues data which |
| 2990 |
|
meant to be read by next read(), but previous read()'s read buffer's |
| 2991 |
|
size was not cleared. As a result, since 1.8.0, sequence like |
| 2992 |
|
|
| 2993 |
|
char *cp = "select global-pid=1\n"; |
| 2994 |
|
read(fd, buf1, sizeof(buf1)); |
| 2995 |
|
write(fd, cp, strlen(cp)); |
| 2996 |
|
read(fd, buf2, sizeof(buf2)); |
| 2997 |
|
|
| 2998 |
|
causes enqueued data to be flushed to buf1 rather than buf2. |

@ Use query id for reaching target process's domain policy. |
| 3001 |
|
|
| 3002 |
|
Use query id for reaching target process's domain policy rather than |
| 3003 |
|
target process's global PID. This is for synchronizing with TOMOYO 2.x, |
| 3004 |
|
but this change makes /usr/sbin/ccs-queryd more reliable because the |
| 3005 |
|
kernel will return empty domain policy when the query has expired before |
| 3006 |
|
ccs-queryd reaches target process's domain policy. |

@ Fix quota counting. |
| 3009 |
|
|
| 3010 |
|
"task manual_domain_transition" should not be counted for quota as with |
| 3011 |
|
"task auto_domain_transition"/"task auto_execute_handler"/ |
| 3012 |
|
"task denied_execute_handler" because these are not appended by learning |
| 3013 |
|
mode. |

|
@ Optimize for object's size. |
| 3018 |
|
|
| 3019 |
|
I rearranged functions/variables into three groups in order to reduce |
| 3020 |
|
object's filesize. Also, I added kernel config options for reducing more |
| 3021 |
|
by excluding unnecessary functionality. |

|
@ Fix kernel config mapping error. |
| 3026 |
|
|
| 3027 |
|
Due to a typo in ccs_p2mac definition, mode for CONFIG::file::execute was |
| 3028 |
|
by error used when checking "file getattr" permission. Most users will |
| 3029 |
|
not be affected by this error because CONFIG::file::execute and |
| 3030 |
|
CONFIG::file::getattr are by default configured to use CONFIG::file or |
| 3031 |
|
CONFIG settings. |

|
@ Follow __d_path() behavior change. (Only 2.6.36 and later) |
| 3036 |
|
|
| 3037 |
|
The behavior of __d_path() has changed in 3.2-rc5. __d_path() now returns |
| 3038 |
|
NULL when the pathname cannot be calculated. You must update to this |
| 3039 |
|
version when using with 3.2-rc5 and later kernels, or the kernel will |
| 3040 |
|
panic because ccs_get_absolute_path() triggers NULL pointer dereference. |
| 3041 |
|
|
| 3042 |
|
The patch that changed the behavior of __d_path() might be backported to |
| 3043 |
|
2.6.36 to 3.1 kernels. You must update to this version if the patch was |
| 3044 |
|
backported, or you will experience the kernel panic as with 3.2-rc5. |
| 3045 |
|
|
| 3046 |
|
The patch that changed the behavior of __d_path() also changed the way of |
| 3047 |
|
handling pathnames under lazy-unmounted directory. Until now, TOMOYO was |
| 3048 |
|
using incomplete pathnames returned by __d_path() when the pathname is |
| 3049 |
|
under lazy-unmounted directory. But from now on, TOMOYO uses different |
| 3050 |
|
pathnames returned by ccs_get_local_path() when the pathname is under |
| 3051 |
|
lazy-unmounted directory (because __d_path() no longer returns it). |
| 3052 |
|
|
| 3053 |
|
Since applications unlikely do lazy unmounts, requesting pathnames under |
| 3054 |
|
lazy-unmounted directory should not happen unless the administrator |
| 3055 |
|
explicitly does lazy unmounts. But pathnames which is defined for such |
| 3056 |
|
conditions in the policy file (if any) will need to be rewritten. |
