mm: use mm->exe_file instead of first VM_EXECUTABLE vma->vm_file

2012-10-09T07:22:18+00:00

Some security modules and oprofile still uses VM_EXECUTABLE for retrieving a task's executable file. After this patch they will use mm->exe_file directly. mm->exe_file is protected with mm->mmap_sem, so locking stays the same.

TOMOYO: Accept \000 as a valid character.

2012-01-17T23:40:59+00:00

TOMOYO 2.5 in Linux 3.2 and later handles Unix domain socket's address. Thus, tomoyo_correct_word2() needs to accept \000 as a valid character, or TOMOYO 2.5 cannot handle Unix domain's abstract socket address.

TOMOYO: Fix quota and garbage collector.

2011-10-12T01:15:20+00:00

Commit 059d84db "TOMOYO: Add socket operation restriction support" and commit 731d37aa "TOMOYO: Allow domain transition without execve()." forgot to update tomoyo_domain_quota_is_ok() and tomoyo_del_acl() which results in incorrect quota counting and memory leak.

TOMOYO: Allow domain transition without execve().

2011-09-13T22:27:06+00:00

To be able to split permissions for Apache's CGI programs which are executed without execve(), add special domain transition which is performed by writing a TOMOYO's domainname to /sys/kernel/security/tomoyo/self_domain interface. This is an API for TOMOYO-aware userland applications. However, since I expect TOMOYO and other LSM modules to run in parallel, this patch does not use /proc/self/attr/ interface in order to avoid conflicts with other LSM modules when it became possible to run multiple LSM modules in parallel.

TOMOYO: Add socket operation restriction support.

TOMOYO: Add environment variable name restriction support.

2011-09-13T22:27:05+00:00

This patch adds support for checking environment variable's names. Although TOMOYO already provides ability to check argv[]/envp[] passed to execve() requests, file execute /bin/sh exec.envp["LD_LIBRARY_PATH"]="bar" will reject execution of /bin/sh if environment variable LD_LIBRARY_PATH is not defined. To grant execution of /bin/sh if LD_LIBRARY_PATH is not defined, administrators have to specify like file execute /bin/sh exec.envp["LD_LIBRARY_PATH"]="/system/lib" file execute /bin/sh exec.envp["LD_LIBRARY_PATH"]=NULL . Since there are many environment variables whereas conditional checks are applied as "&&", it is difficult to cover all combinations. Therefore, this patch supports conditional checks that are applied as "||", by specifying like file execute /bin/sh misc env LD_LIBRARY_PATH exec.envp["LD_LIBRARY_PATH"]="/system/lib" which means "grant execution of /bin/sh if environment variable is not defined or is defined and its value is /system/lib".

TOMOYO: Fix incorrect enforce mode.

2011-09-09T23:08:48+00:00

In tomoyo_get_mode() since 2.6.36, CONFIG::file::execute was by error used in place of CONFIG::file if CONFIG::file::execute was set to other than default. As a result, enforcing mode was not applied in a way documentation says. Signed-off-by: Tetsuo Handa Signed-off-by: James Morris
