@ 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. |

3035 |
|
@ 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. |

3060 |
|
@ Follow changes in 3.3-rc1. |
3061 |
|
|

Remove ipv6_addr_copy() usage. |

@ Follow changes in linux-next. |

3069 |
|
UMH_WAIT_PROC constant (currently 1) is scheduled for renumbering in 3.4. |
3070 |
|
|
3071 |
|
Use UMH_WAIT_PROC constant instead of hardcoded constant in preparation |
3072 |
|
for backporting call_usermodehelper() related changes. If renumbering was |
3073 |
|
backported, you will start experiencing the kernel panic upon execution |
3074 |
|
of external policy loader (i.e. /sbin/ccs-init), for the kernel will no |
3075 |
|
longer wait for completion of external policy loader process. |
3076 |
|
|
3077 |
|
Although I changed to use UMH_WAIT_PROC constant, this change could fail |
3078 |
|
to detect renumbering in 2.6.22 and earlier kernels, for UMH_WAIT_PROC |
3079 |
|
constant is currently available to only 2.6.23 and later kernels. If you |
3080 |
|
started to experience the kernel panic, please check whether renumbering |
3081 |
|
was backported or not. |

@ Fix mount flags checking order. |
3086 |
|
|
3087 |
|
Userspace can pass in arbitrary combinations of MS_* flags to mount(). |
3088 |
|
|
3089 |
|
If both MS_BIND and one of MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE |
3090 |
|
are passed, device name which should be checked for MS_BIND was not |
3091 |
|
checked because MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE had higher |
3092 |
|
priority than MS_BIND. |
3093 |
|
|
3094 |
|
If both one of MS_BIND/MS_MOVE and MS_REMOUNT are passed, device name |
3095 |
|
which should not be checked for MS_REMOUNT was checked because MS_BIND/ |
3096 |
|
MS_MOVE had higher priority than MS_REMOUNT. |
3097 |
|
|
3098 |
|
Fix these bugs by changing priority to MS_REMOUNT -> MS_BIND -> MS_SHARED |
3099 |
|
-> MS_PRIVATE -> MS_SLAVE -> MS_UNBINDABLE -> MS_MOVE as with do_mount() |
3100 |
|
does. |
