Version 1.8.1 2011/04/01 Usability enhancement with "Zettai, Daijoubudayo" release! |

|
|
| 2820 |
|
@ Fix fcntl(F_SETFL, O_APPEND) handling. |
| 2821 |
|
|
| 2822 |
|
Since 1.8.0, TOMOYO was by error checking "file write" permission rather |
| 2823 |
|
than "file append" permission when changing file's writing mode from |
| 2824 |
|
"overwriting" to "append". |
| 2825 |
|
|
| 2826 |
|
This error should impact little (except CentOS 6.0 kernels) because once |
| 2827 |
|
a file was opened for "overwriting" mode, changing that file to "append" |
| 2828 |
|
mode cannot undo overwriting the file. Regarding CentOS 6.0 kernels, |
| 2829 |
|
due to different ACC_MODE definition, TOMOYO was by error needlessly |
| 2830 |
|
checking "file read" permission when fcntl() was requested. |
| 2831 |
|
|
| 2832 |
|
Fix 2011/04/20 |

|
|
| 2834 |
|
@ Remove unused "struct inode *" parameter from hooks. |
| 2835 |
|
|
| 2836 |
|
Since pre-vfs functions were removed on 2010/09/18, "struct inode *" |
| 2837 |
|
parameter which was used for checking parent directory's DAC permission |
| 2838 |
|
is no longer used. |
| 2839 |
|
|
| 2840 |
|
Note that "struct ccsecurity_operations ccsecurity_ops" has changed. |
| 2841 |
|
Loadable kernel modules that depends on it need to be rebuilt. |

|
when generating audit logs for "misc env" permission. |

@ Fix wrong domainname validation. |
| 2853 |
|
|
| 2854 |
|
"<kernel>" + "/foo/\" + "/bar" was by error checked when |
| 2855 |
|
"<kernel> /foo/\* /bar" was given. As a result, legal domainnames like |
| 2856 |
|
"<kernel> /foo/\* /bar" are rejected. |

|
|
| 2860 |
|
@ Add policy namespace support. |
| 2861 |
|
|
| 2862 |
|
To be able to use TOMOYO in LXC environments, I introduced policy |
| 2863 |
|
namespace. Each policy namespace has its own set of domain policy, |
| 2864 |
|
exception policy and profiles, which are all independent of other |
| 2865 |
|
namespaces. |
| 2866 |
|
|
| 2867 |
|
@ Remove CONFIG_CCSECURITY_BUILTIN_INITIALIZERS option. |
| 2868 |
|
|
| 2869 |
|
From now on, exception policy and manager need to be able to handle |
| 2870 |
|
policy namespace (which is a <$namespace> prefix added to each line). |
| 2871 |
|
Thus, space-separated list for CONFIG_CCSECURITY_BUILTIN_INITIALIZERS is |
| 2872 |
|
no longer suitable for handling policy namespace. |
| 2873 |
|
|
| 2874 |
|
Fix 2011/06/10 |
| 2875 |
|
|
| 2876 |
|
@ Allow specifying trigger for activation. |
| 2877 |
|
|
| 2878 |
|
To be able to use TOMOYO under systemd environments where init= parameter |
| 2879 |
|
is used, I changed to allow overriding the trigger for calling external |
| 2880 |
|
policy loader and activating MAC via kernel command line options. |

@ Remove unused "struct inode *" parameter from ccs-patch-\*.diff . |
| 2885 |
|
|
| 2886 |
|
To follow changes I made on 2011/04/20, I removed "struct inode *" from |
| 2887 |
|
ccs_mknod_permission(), ccs_mkdir_permission(), ccs_rmdir_permission(), |
| 2888 |
|
ccs_unlink_permission(), ccs_symlink_permission(), ccs_link_permission(), |
| 2889 |
|
ccs_rename_permission() that are called from fs/namei.c |
| 2890 |
|
net/unix/af_unix.c include/linux/security.c security/security.c . |

If you have your own ccs-patch-*.diff , please update accordingly. |

|
|

|
@ Remove /proc/ccs/.domain_status interface. |
| 2898 |
|
|
| 2899 |
|
Writing to /proc/ccs/.domain_status can be emulated by |
| 2900 |
|
|
| 2901 |
|
( echo "select " $domainname; echo "use_profile " $profile ) | |
| 2902 |
|
/usr/sbin/ccs-loadpolicy -d |
| 2903 |
|
|
| 2904 |
|
and reading from /proc/ccs/.domain_status can be emulated by |
| 2905 |
|
|
| 2906 |
|
grep -A 1 '^<' /proc/ccs/domain_policy | |
| 2907 |
|
awk ' { if ( domainname == "" ) { if ( substr($1, 1, 1) == "<" ) |
| 2908 |
|
domainname = $0; } else if ( $1 == "use_profile" ) { |
| 2909 |
|
print $2 " " domainname; domainname = ""; } } ; ' |
| 2910 |
|
|
| 2911 |
|
. Since this interface is used by only /usr/sbin/ccs-setprofile , |
| 2912 |
|
remove this interface by updating /usr/sbin/ccs-setprofile . |

|
@ Fix /proc/ccs/stat parser. |
| 2917 |
|
|
| 2918 |
|
For optimization, I changed to use simple_strtoul() rather than sscanf() |
| 2919 |
|
in ccs_write_stat(). But it caused parsing failure if space is inserted |
| 2920 |
|
before value (e.g. "Memory used by policy: $value"). |
| 2921 |
|
|
| 2922 |
|
Fix 2011/07/13 |
| 2923 |
|
|
| 2924 |
|
@ Accept "::" notation for IPv6 address. |
| 2925 |
|
|
| 2926 |
|
In order to add network access restriction to TOMOYO 2.4, I backported |
| 2927 |
|
routines for parsing/printing IPv4/IPv6 address from kernel 3.0 into |
| 2928 |
|
TOMOYO 1.8.2. |
| 2929 |
|
Now, IPv6 address accepts "::1" instead of "0:0:0:0:0:0:0:1". |
