|

Fix 2007/08/06 |
| 949 |
|
|
| 950 |
|
@ Remove mount-flags manipulation. |
| 951 |
|
|
| 952 |
|
Until now, administrator is permitted to turn on/off specific mount options |
| 953 |
|
regardless of mount options passed to kernel. |
| 954 |
|
I removed this feature because "exact option matching" sounds better than |
| 955 |
|
"automatic option enabler/disabler". |
| 956 |
|
|
| 957 |
|
@ Remove /proc/ccs/info/mapping . |
| 958 |
|
|
| 959 |
|
I removed /proc/ccs/info/mapping because nobody seems to use this feature. |
| 960 |
|
|
| 961 |
|
@ Call external policy loader automatically. |
| 962 |
|
|
| 963 |
|
Until now, users had to add init=/.init parameter to load policy |
| 964 |
|
before /sbin/init starts. |
| 965 |
|
I inserted call_usermodehelper() to call external policy loader when |
| 966 |
|
execve("/sbin/init") is requested and external policy loader exists. |
| 967 |
|
|
| 968 |
|
This change will remove init=/.init parameter from most environment, |
| 969 |
|
although call_usermodehelper() can't handle interactive operations. |
| 970 |
|
|
| 971 |
|
@ Move external policy loader from /.init to /sbin/ccs-init . |

|

Fix 2007/08/13 |
| 976 |
|
|
| 977 |
|
@ Update external policy loader. |
| 978 |
|
|
| 979 |
|
It turned out that /sbin/ccs-init invoked via call_usermodehelper() |
| 980 |
|
can handle interactive operations by opening /dev/console . |
| 981 |
|
Now, there is no difference between init=/sbin/ccs-init and |
| 982 |
|
call_usermodehelper("/sbin/ccs-init"), and users no longer need to |
| 983 |
|
add init=/sbin/ccs-init parameter to load policy before /sbin/init starts. |
| 984 |
|
|

|
Fix 2007/08/14 |
| 986 |
|
|
| 987 |
|
@ Update recvmsg() hooks. |
| 988 |
|
|
| 989 |
|
Until now, it was impossible to apply network access control for |
| 990 |
|
incoming UDP and RAW packets if they are brought to userland using |
| 991 |
|
read() or recvmsg() with NULL address because address buffer is NULL. |
| 992 |
|
I moved hooks from sock_recvmsg() to skb_recv_datagram() so that |
| 993 |
|
network access control for incoming UDP and RAW packets always work. |
| 994 |
|
|

Fix 2007/08/16 |

|
|
| 997 |
|
@ Return appropriate error code for CheckMountPermission(). |
| 998 |
|
|
| 999 |
|
I was returning -EPERM if something is wrong with CheckMountPermission(). |
| 1000 |
|
But SELinux determines whether selinuxfs is supported by kernel |
| 1001 |
|
based on whether error code is -ENODEV or not. |
| 1002 |
|
So I stopped returning -EPERM unconditionally. |

|
|
| 1027 |

I need to remove head message from unwanted source |

|
@ Avoid eating memory after quota exceeded. |
| 1036 |
|
|
| 1037 |
|
Although ACL entries in a domain won't be added if the domain's quota |
| 1038 |
|
has exceeded, SaveName() in AddFileACL() is called anyway. |
| 1039 |
|
This caused unneeded memory consumption. |
| 1040 |
|
|
| 1041 |
|
Now, quota checking is done before getting domain_acl_lock lock. |
| 1042 |
|
This may exceed quota by one or two entries, but that won't matter. |
| 1043 |
|
|

Fix 2007/10/16 |
| 1045 |
|
|

|
@ Add environment variable check. |
| 1047 |
|
|
| 1048 |
|
There are environment variables that may cause dangerous behavior |
| 1049 |
|
like LD_\* . |
| 1050 |
|
So I introduced 'allow_env' directive that allows specified |
| 1051 |
|
environment variable inherited to next domain. |
| 1052 |
|
Unlike other permissions, this check is done at execve() time |
| 1053 |
|
using next domain's ACL information. |
| 1054 |
|
|
| 1055 |
|
To manage commonly inherited environments like PATH , |
| 1056 |
|
you can use 'allow_env' directive in exception policy |
| 1057 |
|
to globally grant specified environment variable. |

| 1065 |
|
@ Add missing down() in AddReservedEntry(). |
| 1066 |
|
|
| 1067 |
|
Mutex debugging capability told me that I had forgotten to call down() |
| 1068 |
|
since TOMOYO version 1.3.2 . |
| 1069 |
|
This function is not called by learning mode, |
| 1070 |
|
so the semaphore's counter will not overflow for normal usage. |

@ Fix ReadTable() truncation bug. |
| 1075 |
|
|
| 1076 |
|
"snprintf(str, size, format, ...) >= size" means truncated. |
| 1077 |
|
But I was checking for "snprintf(str, size, format, ...) > size". |
| 1078 |
|
As a result, some entries might be dumped without '\n'. |
| 1079 |
|
|
| 1080 |
|
@ Purge direct "->prev"/"->next" manipulation. |
| 1081 |
|
|
| 1082 |
|
All list manipulations use "struct list_head" or "struct list1_head". |
| 1083 |
|
"struct list1_head" doesn't have "->prev" member to save memory usage. |
| 1084 |

@ Fix AddMountACL() rejection bug. |

not only "both source and dest are directory" |
