System call entry functions sys_*() are never to be called from general kernel code. The fact that they aren't declared in header files should have been a clue. These functions also don't exist on Alpha since it has sys_getxpid() instead.

Commit c9e69318 "TOMOYO: Allow wildcard for execute permission." changed execute permission and domainname to accept wildcards. But tomoyo_find_next_domain() was using pathname passed to execve() rather than pathname specified by the execute permission. As a result, processes were not able to transit to domains which contain wildcards in their domainnames. This patch passes pathname specified by the execute permission back to tomoyo_find_next_domain() so that processes can transit to domains which contain wildcards in their domainnames.

When userspace program reads policy from /sys/kernel/security/tomoyo/ interface, TOMOYO uses line buffered mode. A line has at least one word. Commit 006dacc "TOMOYO: Support longer pathname." changed a word's max length from 4000 bytes to max kmalloc()able bytes. By that commit, a line's max length changed from 8192 bytes to more than max kmalloc()able bytes. Max number of words in a line remains finite. This patch changes the way of buffering so that all words in a line are firstly directly copied to userspace buffer as much as possible and are secondly queued for next read request. Words queued are guaranteed to be valid until /sys/kernel/security/tomoyo/ interface is close()d.

Some programs behave differently depending on argv[0] passed to execve(). TOMOYO has "alias" keyword in order to allow administrators to define different domains if requested pathname passed to execve() is a symlink. But "alias" keyword is incomplete because this keyword assumes that requested pathname and argv[0] are identical. Thus, remove "alias" keyword (by this patch) and add syntax for checking argv[0] (by future patches).

This patch allows users to change access control mode for per-operation basis. This feature comes from non LSM version of TOMOYO which is designed for permitting users to use SELinux and TOMOYO at the same time. SELinux does not care filename in a directory whereas TOMOYO does. Change of filename can change how the file is used. For example, renaming index.txt to .htaccess will change how the file is used. Thus, letting SELinux to enforce read()/write()/mmap() etc. restriction and letting TOMOYO to enforce rename() restriction is an example usage of this feature. What is unfortunate for me is that currently LSM does not allow users to use SELinux and LSM version of TOMOYO at the same time...

Since the behavior of the system is restricted by policy, we may need to update policy when you update packages. We need to update policy in the following cases. * The pathname of files has changed. * The dependency of files has changed. * The access permissions required has increased. The ideal way to update policy is to rebuild from the scratch using learning mode. But it is not desirable to change from enforcing mode to other mode if the system has once entered in production state. Suppose MAC could support per-application enforcing mode, the MAC becomes useless if an application that is not running in enforcing mode was cracked. For example, the whole system becomes vulnerable if only HTTP server application is running in learning mode to rebuild policy for the application. So, in TOMOYO Linux, updating policy is done while the system is running in enforcing mode. This patch implements "interactive enforcing mode" which allows administrators to judge whether to accept policy violation in enforcing mode or not.

Some of TOMOYO's functions may sleep after mutex_lock(). If OOM-killer selected a process which is waiting at mutex_lock(), the to-be-killed process can't be killed. Thus, replace mutex_lock() with mutex_lock_interruptible() so that the to-be-killed process can immediately return from TOMOYO's functions.
