| * security: remove the security_netlink_recv hook as it is equivalent to capable()Eric Paris2012-01-05
| | | | | | | | | | | | | | | | | | | | Once upon a time netlink was not sync and we had to get the effective capabilities from the skb that was being received. Today we instead get the capabilities from the current task. This has rendered the entire purpose of the hook moot as it is now functionally equivalent to the capable() call.

| * ptrace: do not audit capability check when outputing /proc/pid/statEric Paris2012-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reading /proc/pid/stat of another process checks if one has ptrace permissions on that process. If one does have permissions it outputs some data about the process which might have security and attack implications. If the current task does not have ptrace permissions the read still works, but those fields are filled with inocuous (0) values. Since this check and a subsequent denial is not a violation of the security policy we should not audit such denials. This can be quite useful to removing ptrace broadly across a system without flooding the logs when ps is run or something which harmlessly walks proc.

| * capabilities: remove the task from capable LSM hook entirelyEric Paris2012-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The capabilities framework is based around credentials, not necessarily the current task. Yet we still passed the current task down into LSMs from the security_capable() LSM hook as if it was a meaningful portion of the security decision. This patch removes the 'generic' passing of current and instead forces individual LSMs to use current explicitly if they think it is appropriate. In our case those LSMs are SELinux and AppArmor. I believe the AppArmor use of current is incorrect, but that is wholely unrelated to this patch. This patch does not change what AppArmor does, it just makes it clear in the AppArmor code that it is doing it. The SELinux code still uses current in it's audit message, which may also be wrong and needs further investigation. Again this is NOT a change, it may have always been wrong, this patch just makes it clear what is happening. Signed-off-by: Eric Paris <eparis@redhat.com>

* VFS : mount lock scalability for internal mountsTim Chen2011-07-24
| | | | | | | | | | | | | | | | | | | For a number of file systems that don't have a mount point (e.g. sockfs and pipefs), they are not marked as long term. Therefore in mntput_no_expire, all locks in vfs_mount lock are taken instead of just local cpu's lock to aggregate reference counts when we release reference to file objects. In fact, only local lock need to have been taken to update ref counts as these file systems are in no danger of going away until we are ready to unregister them. The attached patch marks file systems using kern_mount without mount point as long term. The contentions of vfs_mount lock is now eliminated. Before un-registering such file system, kern_unmount should be called to remove the long term flag and make the mount point ready to be freed.

| * | selinux: fix case of names with whitespace/multibytes on /selinux/createKohei Kaigai2011-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I submit the patch again, according to patch submission convension. This patch enables to accept percent-encoded object names as forth argument of /selinux/create interface to avoid possible bugs when we give an object name including whitespace or multibutes. E.g) if and when a userspace object manager tries to create a new object named as "resolve.conf but fake", it shall give this name as the forth argument of the /selinux/create. But sscanf() logic in kernel space fetches only the part earlier than the first whitespace. In this case, selinux may unexpectedly answer a default security context configured to "resolve.conf", but it is bug. Although I could not test this patch on named TYPE_TRANSITION rules actually, But debug printk() message seems to me the logic works correctly. I assume the libselinux provides an interface to apply this logic transparently, so nothing shall not be changed from the viewpoint of application.
