2014-06-12tomoyo: Use sensible time interfaceThomas Gleixner1-5/+3
There is no point in calling gettimeofday if only the seconds part of the timespec is used. Use get_seconds() instead. It's not only the proper interface it's also faster.

2012-03-15TOMOYO: Return appropriate value to poll().Tetsuo Handa1-2/+2
"struct file_operations"->poll() expects "unsigned int" return value. All files in /sys/kernel/security/tomoyo/ directory other than /sys/kernel/security/tomoyo/query and /sys/kernel/security/tomoyo/audit should return POLLIN | POLLRDNORM | POLLOUT | POLLWRNORM rather than -ENOSYS. Also, /sys/kernel/security/tomoyo/query and /sys/kernel/security/tomoyo/audit should return POLLOUT | POLLWRNORM rather than 0 when there is no data to read.

2011-09-14TOMOYO: Allow controlling generation of access granted logs for per an entry basis.Tetsuo Handa1-1/+6
Add per-entry flag which controls generation of grant logs because Xen and KVM issues ioctl requests so frequently. For example, file ioctl /dev/null 0x5401 grant_log=no will suppress /sys/kernel/security/tomoyo/audit even if preference says grant_log=yes .

2011-06-29TOMOYO: Add policy namespace support.Tetsuo Handa1-3/+5
Mauras Olivier reported that it is difficult to use TOMOYO in LXC environments, for TOMOYO cannot distinguish between environments outside the container and environments inside the container since LXC environments are created using pivot_root(). To address this problem, this patch introduces policy namespace. Each policy namespace has its own set of domain policy, exception policy and profiles, which are all independent of other namespaces. This independency allows users to develop policy without worrying interference among namespaces.

2011-06-29TOMOYO: Add auditing interface.Tetsuo Handa1-0/+300
Add /sys/kernel/security/tomoyo/audit interface. This interface generates audit logs in the form of domain policy so that /usr/sbin/tomoyo-auditd can reuse audit logs for appending to /sys/kernel/security/tomoyo/domain_policy interface.
