TOMOYO

Fork

Fix 2006/06/13

@ Merge tomoyo_connect.c and tomoyo_bind.c into tomoyo_port.c

I merged these files that have only difference CONNECT and BIND,
that are likely to be enabled both or neither.

@ Add CONFIG_TOMOYO_AUDIT option.

I made auditing functions as optional because some Linux boxes
may have not enough disk space to store audit logs.

@ Support use of symbolic links for program execution.

Until now, domains for programs executed by dereferencing
symbolic links were defined using dereferenced pathnames.
This was inconvenient for some Linux boxes who use busybox but
can't keep hard links of busybox.
I introduced a mechanism to allow using pathnames of
symbolic links using 'alias' directive.
Some examples:

'alias /sbin/busybox /bin/ls' to run /bin/ls
(which is a symbolic link to /sbin/busybox) as /bin/ls
if /bin/ls is executed.

'alias /bin/bash /bin/sh' to run /bin/sh
(which is a symbolic link to /bin/bash) as /bin/sh
if /bin/sh is executed.

@ Use ccs_alloc() instead of kzalloc().

To detect memory leaks,
I added a wrapper for tracing kmalloc() and kfree().
There is no way to detect memory leaks caused by ccs-*.txt .

Version 1.1.3 2006/07/13 Functionality enhancement release.
