@ Use 'unsigned int' for sscanf(). |
861 |
|
|
862 |
|
I compiled SYAORAN fs on x86_64 environment and found |
863 |
|
the compiler showing warning messages about size of data types. |
864 |
|
Since size of data types may mismatch for sscanf(), |
865 |
|
I replaced some types with 'unsigned int'. |

|
@ Change argv[0] checking rule. |
872 |
|
|
873 |
|
I was comparing the basename of symbolic link's pathname and argv[0]. |
874 |
|
Since execute permission check and domain transition are done |
875 |
|
based on realpath while argv[0] check is done based on the symlink's |
876 |
|
pathname and argv[0], this specification will allow attackers behave |
877 |
|
as /bin/cat in the domain of /bin/ls if "/bin/ls and /bin/cat are |
878 |
|
links to /sbin/busybox" and "the attacker is permitted to create |
879 |
|
a symlink named ~/cat that points to /bin/ls" and "the attacker is |
880 |
|
permitted to run /bin/ls". |
881 |
|
So, I changed to compare the basename of realpath and argv[0]. |
882 |
|
Also, I moved the location to compare before processing |
883 |
|
"aggregator" directive so that |
884 |
|
"aggregator /tmp/logrotate.\?\?\?\?\?\? /tmp/logrotate.tmp" |
885 |
|
won't cause the mismatch of the basename of realpath and argv[0]. |
886 |
|
|
887 |
|
If /bin/ls is a symlink to /sbin/busybox, then |
888 |
|
creating a symlink named ~/cat that points to /bin/ls and |
889 |
|
executing ~/cat won't work as expected because permission check and |
890 |
|
domain transition are done using /sbin/busybox (realpath of /bin/ls) |
891 |
|
and will be rejected since the administrator won't grant |
892 |
|
"1 /sbin/busybox". |

@ Support pathname subtraction. |
897 |
|
|
898 |
|
There was no way to exclude specific pathnames when granting |
899 |
|
permissions using wildcards. |
900 |
|
There would be a need to exclude specific files and directories. |
901 |
|
I introduced "\-" as subtraction operator. |
902 |
|
|
903 |
|
"A\-B" means "A" other than "B". |
904 |
|
"A\-B\-C" means "A" other than "B" and "C". |
905 |
|
"A\-B\-C\-D" means "A" other than "B" and "C" and "D". |
906 |
|
|
907 |
|
"A", "B", "C", "D" may contain wildcards. |
908 |
|
|
909 |
|
An example usage is "/home/\*/\*\-.ssh/\*", which means |
910 |
|
"/home/\*/\*/\*" other than "/home/\*/.ssh/\*". |
911 |
|
|
912 |
|
"A" should contain wildcards because subtraction from constants |
913 |
|
(e.g. "/usr\-usr/" or "/usr\-home/") is meaningless. |
914 |
|
|
915 |
|
Don't try "A\-B\+C" because "\+" is not addition operator. |

|
@ 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 |

|
@ 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 . |
972 |
|

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. |

@ 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. |

@ 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. |
