Fix 2006/01/04

    @ Add CheckWritePermission() check in unix_bind().

      I modified to check write permission in unix_bind(), for
      sys_mknod(S_IFSOCK) checks write permission.

    @ Show hook version in proc_misc_init().

      The hook part of this patch depends on the kernel's version,
      while the rest part of this patch doesn't.
      I added the hook version so that the administrator can
      know the last modified date of the hooks.

    @ Move permission checks from filp_open() to open_namei().

      I moved the location of checking MAC's permission
      from filp_open() to open_namei().

    @ Fix an error in filp_open().  (only 2.6.15-rc5)

      This error was only in the patch 2.6.15-rc5 and
      was fixed in the patch for 2.6.15.

    @ Add /proc/ccs/info/self_domain.

      I added /proc/ccs/info/self_domain so that the userland programs
      can know the name of domain they belong to if necessary.

    @ Merge constants for CheckTaskCapability().

      I merged *_INHERITABLE_* and *_LOCAL_* to avoid always
      calling CheckTaskCapability() with both constants.

    @ DropTaskCapability() returns -EAGAIN on success.

      DropTaskCapability() must not return 0 on success, for
      DropTaskCapability() is called from do_execve().

    @ Fix an error for chroot() permission check.

      The chroot() restriction was not working due to the following mistake.
      CheckChRootPermission() || CheckTaskCapability() returns 0 or 1, while
      CheckChRootPermission() | CheckTaskCapability() returns 0 or -EPERM.

Fix 2006/01/17

    @ Suppress some of debug messages in TOMOYO.

      I added KERN_DEBUG to suppress some of debug messages.

Fix 2006/01/19

    @ Remove isRoot() checks in AddChrootACL() and AddMountACL().

      I found a program that needs to chroot by non-root.
      So, I stopped checking uid=euid=0 for these functions so that
      "accept mode" can append ACLs.
      The isRoot() is checked at AddChrootPolicy() and AddMountPolicy().

    @ Map NULL device name to "<NULL>" in AddMountACL().

      VMware mounts vmware-hgfs with NULL device name.
      So I mapped NULL device name to "<NULL>".

Fix 2006/01/20

    @ Suppress some of debug messages in SAKURA.

      I added KERN_DEBUG to suppress some of debug messages.

    @ Call panic() if failed to load given profile.

      Call panic() if profile index was given via CCS= parameter
      but the profile doesn't exist.
      If CCS= parameter is not given, the kernel attempts to load
      profile 0, but it doesn't call panic() if profile 0 doesn't exist.

Fix 2006/01/24

    @ Use full_name_hash() for IsGloballyReadableFile().

      I modified to use full_name_hash() for faster scan.

    @ Add signal checking condition in CheckSignalACL().

      The documentation says "if the target domain's domainname
      starts with the source domain's domainname, it is always granted"
      but actually it isn't. I'll change the documentation instead of
      changing the source code.

      Also, checking for pid = -1 was missing. This error was fixed.

Fix 2006/02/09

    @ Use mutex_lock()/mutex_unlock instead of down()/up().

      Kernel 2.6.16 changed members of "struct inode".
      I modified to use mutex_lock()/mutex_unlock() for after 2.6.16
      and down()/up() for before 2.6.16.

Version 1.0.2 2006/02/14   Many bug-fixes release.
