|
@ Use kmap_atomic()/kunmap_atomic() for reading "struct linux_binprm". |
| 1803 |

|
| 1804 |

As remove_arg_zero() uses kmap_atomic(KM_USER0), I modified to use |
| 1805 |

kmap_atomic(KM_USER0) rather than kmap(). |

|
@ Fix "allow_read" + "allow_write" != "allow_read/write" problem. |
| 1810 |
|
|
| 1811 |
|
Since 1.6.0 , due to a bug in ccs_update_single_path_acl(), |
| 1812 |
|
appending "allow_read/write" entry didn't update internal "allow_read" |
| 1813 |
|
and "allow_write" entries. As a result, attempt to open(O_RDWR) succeeds |
| 1814 |
|
but open(O_RDONLY) and open(O_WRONLY) fail. |
| 1815 |
|
|
| 1816 |
|
Workaround is to write an entry twice when newly appending that entry. |
| 1817 |
|
If written twice, internal "allow_read" and "allow_write" entries |
| 1818 |
|
are updated. |

@ Fix profile read error. |

Incorrect profiles were shown in /proc/ccs/profile |

|
@ Undelete CONFIG_TOMOYO_AUDIT option. |
| 1830 |
|
|
| 1831 |
|
While HDD-less systems can use profiles with MAX_GRANT_LOG=0 and |
| 1832 |
|
MAX_REJECT_LOG=0 , I undeleted CONFIG_TOMOYO_AUDIT option for saving |
| 1833 |
|
memory used for /proc/ccs/grant_log and /proc/ccs/reject_log interfaces. |

|
|
| 1837 |
|
@ Show only profile entry names ever specified. |
| 1838 |
|
|
| 1839 |
|
Even if an administrator specifies only COMMENT= and MAC_FOR_FILE= |
| 1840 |
|
entries for /proc/ccs/profile , all available profile entries are shown. |
| 1841 |
|
This was designed to help administrators to know what entries are |
| 1842 |
|
available, but sometimes makes administrators feel noisy because of |
| 1843 |
|
entries showing default values. |
| 1844 |
|
|
| 1845 |
|
Thus, I modified to show only profile entry names ever specified. |

|
@ Add MAC_FOR_IOCTL functionality. |
| 1850 |
|
|
| 1851 |
|
To be able to restrict ioctl() requests, I added MAC_FOR_IOCTL |
| 1852 |
|
functionality. |
| 1853 |
|
|
| 1854 |
|
This functionality requires modification of ccs-patch-\*.diff . |
| 1855 |
|
|
| 1856 |
|
@ Use better name for socket's pathname. |
| 1857 |
|
|
| 1858 |
|
Until now, socket's pathname was represented as "socket:[\$]" format |
| 1859 |
|
where \$ is inode's number. But inode's number is useless for name based |
| 1860 |
|
access control. Therefore, I modified to represent socket's pathname as |
| 1861 |
|
"socket:[family=\$:type=\$:protocol=\$]" format. |
| 1862 |
|
|
| 1863 |
|
This will help administrator to control ioctl() against sockets more |
| 1864 |
|
precisely. |

|
@ Fix misplaced ccs_capable() call. (only 2.6.8-\* and 2.6.9-\*) |
| 1867 |
|
|
| 1868 |
|
Location to insert ccs_capable(TOMOYO_SYS_IOCTL) in sys_ioctl() was |
| 1869 |
|
wrong since version 1.1 . |

|
|
| 1871 |
|
@ Insert ccs_check_ioctl_permission() call. |
| 1872 |
|
|
| 1873 |
|
To make MAC_FOR_IOCTL functionality working, I inserted |
| 1874 |
|
ccs_check_ioctl_permission() call into ccs-patch-\*.diff . |
| 1875 |
|
|

|
@ Move sysctl()'s check from ccs-patch-\*.diff to fs/tomoyo_file.c . |
| 1879 |
|
|
| 1880 |
|
Since try_parse_table() in kernel/sysctl.c is almost identical between |
| 1881 |
|
all versions, I moved that function to fs/tomoyo_file.c . |
| 1882 |
|
|
| 1883 |
|
@ Relocate definitions and functions. |
| 1884 |
|
|
| 1885 |
|
To reduce exposed symbols, I relocated some definitions and functions. |

|
|
| 1891 |

Some systems don't have /sbin/modprobe and /sbin/hotplug . |
| 1892 |

Thus, I made these pathnames configurable. |

@ Drop "undelete domain" command. |
| 1899 |
|
|
| 1900 |
|
I added "undelete domain" command on 2007/01/19, but never used by policy |
| 1901 |
|
management tools. The garbage collector I added on 2007/01/29 will |
| 1902 |
|
automatically reuse memory and allow administrators switch domain policy |
| 1903 |
|
periodically, provided that the administrator kills processes in old |
| 1904 |
|
domains before recreating new domains with the same domainnames. |
| 1905 |
|
|
| 1906 |
|
Thus, I dropped "undelete domain" command. |

@ Escape invalid characters in ccs_check_mount_permission2(). |
| 1909 |
|

| 1910 |
|
ccs_check_mount_permission2() was passing unencoded strings to printk() |
| 1911 |
|
and ccs_update_mount_acl() and ccs_check_supervisor(). This may cause |
| 1912 |
|
/proc/ccs/system_policy and /proc/ccs/query to contain invalid |
| 1913 |
|
characters within a string. |

@ Fix IPv4's "address_group" handling error. |
| 1918 |
|
|
| 1919 |
|
Since 1.6.5 , due to lack of ntohl() (byte order conversion) in |
| 1920 |
|
ccs_update_address_group_entry(), "address_group" with IPv4 address was |
| 1921 |
|
not working. |
| 1922 |

This problem happens on little endian platforms (e.g. x86). |

@ Update recvmsg() hooks. |
| 1928 |
|
|
| 1929 |
|
Since 1.5.0, I was doing network access control for incoming UDP and RAW |
| 1930 |
|
packets inside skb_recv_datagram(). But to synchronize with LSM version, |
| 1931 |
|
I moved ccs_recv_datagram_permission() hook from skb_recv_datagram() to |
| 1932 |
|
udp_recvmsg()/udpv6_recvmsg()/raw_recvmsg()/rawv6_recvmsg() with name |
| 1933 |
|
change to ccs_recvmsg_permission(). |
