The initial ENAMETOOLONG error was being lost, and ENAMETOOLONG was only returned if the subsequent dentry_path call resulted in that error. Other wise if the path was split across a mount point such that the dentry_path fit within the buffer when the __d_path did not the failure was treated as a disconnected path.

* | Add PR_{GET,SET}_NO_NEW_PRIVS to prevent execve from granting privsAndy Lutomirski2012-04-141-0/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this change, calling prctl(PR_SET_NO_NEW_PRIVS, 1, 0, 0, 0) disables privilege granting operations at execve-time. For example, a process will not be able to execute a setuid binary to change their uid or gid if this bit is set. The same is true for file capabilities. Additionally, LSM_UNSAFE_NO_NEW_PRIVS is defined to ensure that LSMs respect the requested behavior. To determine if the NO_NEW_PRIVS bit is set, a task may call prctl(PR_GET_NO_NEW_PRIVS, 0, 0, 0, 0); It returns 1 if set and 0 if it is not set. If any of the arguments are non-zero, it will return -1 and set errno to -EINVAL. (PR_SET_NO_NEW_PRIVS behaves similarly.) This functionality is desired for the proposed seccomp filter patch series. By using PR_SET_NO_NEW_PRIVS, it allows a task to modify the system call behavior for itself and its child tasks without being able to impact the behavior of a more privileged task. Another potential use is making certain privileged operations unprivileged. For example, chroot may be considered "safe" if it cannot affect privileged tasks. Note, this patch causes execve to fail when PR_SET_NO_NEW_PRIVS is set and AppArmor is in use. It is fixed in a subsequent patch.

| | | | | | | | | | | | Linus found that the gigantic size of the common audit data caused a big perf hit on something as simple as running stat() in a loop.

| | | | | | | | | | | | | | | | | | Fix failure in aa_change_onexec api when the request is made from a confined task. This failure was caused by two problems The AA_MAY_ONEXEC perm was not being mapped correctly for this case.

This mistake can not be exploited to grant extra permission because of the above flaw where the ONEXEC permission was not being mapped so it will not be granted.

In properly compiled policy this should not happen for file rules but it may be possible for other rule types in the future. To exploit this underflow a user would have to be able to load a corrupt policy, which requires CAP_MAC_ADMIN, overwrite system policy in kernel memory or know of a compiler error resulting in the flaw being present for loaded policy (no such flaw is known at this time).

| * capabilities: remove the task from capable LSM hook entirelyEric Paris2012-01-061-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

The root cause is that when __d_path() misses the root it had been told to look for, it stores the location of the most remote ancestor in *root. Without grabbing references. Sure, at the moment of call it had been pinned down by what we have in *path. And if we raced with umount -l, we could have very well stopped at vfsmount/dentry that got freed as soon as prepend_path() dropped vfsmount_lock. It is safe to compare these pointers with pre-existing (and known to be still alive) vfsmount and dentry, as long as all we are asking is "is it the same address?". Dereferencing is not safe and apparmor ended up stepping into that. d_namespace_path() really wants to examine the place where we stopped, even if it's not connected to our namespace. As the result, it looked at ->d_sb->s_magic of a dentry that might've been already freed by that point. All other callers had been careful enough to avoid that, but it's really a bad interface - it invites that kind of trouble. The fix is fairly straightforward, even though it's bigger than I'd like: * prepend_path() root argument becomes const. * __d_path() is never called with NULL/NULL root. It was a kludge to start with. Instead, we have an explicit function - d_absolute_root(). Same as __d_path(), except that it doesn't get root passed and stops where it stops. apparmor and tomoyo are using it. * __d_path() returns NULL on path outside of root. The main caller is show_mountinfo() and that's precisely what we pass root for - to skip those outside chroot jail. Those who don't want that can (and do) use d_path(). * __d_path() root argument becomes const. Everyone agrees, I hope. * apparmor does *NOT* try to use __d_path() or any of its variants when it sees that path->mnt is an internal vfsmount. In that case it's definitely not mounted anywhere and dentry_path() is exactly what we want there. Handling of sysctl()-triggered weirdness is moved to that place. * if apparmor is asked to do pathname relative to chroot jail and __d_path() tells it we it's not in that jail, the sucker just calls d_absolute_path() instead. That's the other remaining caller of __d_path(), BTW. * seq_path_root() does _NOT_ return -ENAMETOOLONG (it's stupid anyway - the normal seq_file logics will take care of growing the buffer and redoing the call of ->show() just fine). However, if it gets path not reachable from root, it returns SEQ_SKIP. The only caller adjusted (i.e. stopped ignoring the return value as it used to do).
