Tetsuo Handa eadd99cc85 TOMOYO: Add auditing interface.
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.

Roberto Sassu 79a73d1887 encrypted-keys: add ecryptfs format support
The 'encrypted' key type defines its own payload format which contains a
symmetric key randomly generated that cannot be used directly to mount
an eCryptfs filesystem, because it expects an authentication token
structure.

This patch introduces the new format 'ecryptfs' that allows to store an
authentication token structure inside the encrypted key payload containing
a randomly generated symmetric key, as the same for the format 'default'.

More details about the usage of encrypted keys with the eCryptfs
filesystem can be found in the file 'Documentation/keys-ecryptfs.txt'.

Roberto Sassu 4e561d388f encrypted-keys: add key format support
This patch introduces a new parameter, called 'format', that defines the
format of data stored by encrypted keys. The 'default' format identifies
encrypted keys containing only the symmetric key, while other formats can
be defined to support additional information. The 'format' parameter is
written in the datablob produced by commands 'keyctl print' or
'keyctl pipe' and is integrity protected by the HMAC.

eparis@redhat 2ce9738bac cgroupfs: use init_cred when populating new cgroupfs mount
We recently found that in some configurations SELinux was blocking the ability
for cgroupfs to be mounted.  The reason for this is because cgroupfs creates
files and directories during the get_sb() call and also uses lookup_one_len()
during that same get_sb() call.  This is a problem since the security
subsystem cannot initialize the superblock and the inodes in that filesystem
until after the get_sb() call returns.  Thus we leave the inodes in
an unitialized state during get_sb().  For the vast majority of filesystems
this is not an issue, but since cgroupfs uses lookup_on_len() it does
search permission checks on the directories in the path it walks.  Since the
inode security state is not set up SELinux does these checks as if the inodes
were 'unlabeled.'

Many 'normal' userspace process do not have permission to interact with
unlabeled inodes.  The solution presented here is to do the permission checks
of path walk and inode creation as the kernel rather than as the task that
called mount.  Since the kernel has permission to read/write/create
unlabeled inodes the get_sb() call will complete successfully and the SELinux
code will be able to initialize the superblock and those inodes created during
the get_sb() call.

This appears to be the same solution used by other filesystems such as devtmpfs
to solve the same issue and should thus have no negative impact on other LSMs
which currently work.

Linus Torvalds 13e12d14e2 vfs: reorganize 'struct inode' layout a bit
This tries to make the 'struct inode' accesses denser in the data cache
by moving a commonly accessed field (i_security) closer to other fields
that are accessed often.

It also makes 'i_state' just an 'unsigned int' rather than 'unsigned
long', since we only use a few bits of that field, and moves it next to
the existing 'i_flags' so that we potentially get better structure
layout (although depending on config options, i_flags may already have
packed in the same word as i_lock, so this improves packing only for the
case of spinlock debugging)

Out 'struct inode' is still way too big, and we should probably move
some other fields around too (the acl fields in particular) for better
data cache access density.  Other fields (like the inode hash) are
likely to be entirely irrelevant under most loads.

Linus Torvalds 95f4efb2d7 selinux: simplify and clean up inode_has_perm()
This is a rather hot function that is called with a potentially NULL
"struct common_audit_data" pointer argument.  And in that case it has to
provide and initialize its own dummy common_audit_data structure.

However, all the _common_ cases already pass it a real audit-data
structure, so that uncommon NULL case not only creates a silly run-time
test, more importantly it causes that function to have a big stack frame
for the dummy variable that isn't even used in the common case!

So get rid of that stupid run-time behavior, and make the (few)
functions that currently call with a NULL pointer just call a new helper
function instead (naturally called inode_has_perm_noapd(), since it has
no adp argument).

This makes the run-time test be a static code generation issue instead,
and allows for a much denser stack since none of the common callers need
the dummy structure.  And a denser stack not only means less stack space
usage, it means better cache behavior.  So we have a win-win-win from
this simplification: less code executed, smaller stack footprint, and
better cache behavior.

Linus Torvalds 81de916f19 tty_buffer: get rid of 'seen_tail' logic in flush_to_ldisc
The flush_to_ldisc() work entry has special logic to notice when it has
seen the original tail of the data queue, and it avoids continuing the
flush if it sees that _original_ tail rather than the current tail.

This logic can trigger in case somebody is constantly adding new data to
the tty while the flushing is active - and the intent is to avoid
excessive CPU usage while flushing the tty, especially as we used to do
this from a softirq context which made it non-preemptible.

However, since we no longer re-arm the work-queue from within itself
(because that causes other trouble: see commit a5660b41af "tty: fix
endless work loop when the buffer fills up"), this just leads to
possible hung tty's (most easily seen in SMP and with a test-program
that floods a pty with data - nobody seems to have reported this for any
real-life situation yet).

And since the workqueue isn't done from timers and softirq's any more,
it's doubtful whether the CPU useage issue is really relevant any more.
So just remove the logic entirely, and see if anybody ever notices.

Alternatively, we might want to re-introduce the "re-arm the work" for
just this case, but then we'd have to re-introduce the delayed work
model or some explicit timer, which really doesn't seem worth it for
this.

Daniel Haid 62fff811d7 drm/radeon/kms: fix for radeon on systems >4GB without hardware iommu
On my x86_64 system with >4GB of ram and swiotlb instead of
a hardware iommu (because I have a VIA chipset), the call
to pci_set_dma_mask (see below) with 40bits returns an error.

But it seems that the radeon driver is designed to have
need_dma32 = true exactly if pci_set_dma_mask is called
with 32 bits and false if it is called with 40 bits.

I have read somewhere that the default are 32 bits. So if the
call fails I suppose that need_dma32 should be set to true.

And indeed the patch fixes the problem I have had before
and which I had described here:

Wierdly the kms parser never initialised the family, it wasn't really used
much, but the fmt checker patch started using it and it fell over.

Grant Likely 22b174f8b7 MAINTAINERS: Saying goodbye to David Brownell
We had to say goodbye when David passed away recently.  David had a
huge impact on our community, both personally in the lives of the
people he worked with, and technically in the design and maintenance
of several subsystems.  He is greatly missed.

He also leaves behind a number of much loved subsystems now orphaned.
This patch updates the MAINTAINERS file for the areas that David was
responsible for and adds an entry for him to the CREDITS file.

David Howells db1c9dfa64 MN10300: die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs()
die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs() to
indicate that it wants to probe a kernel address.  Instead it should use
probe_kernel_read().

This fixes the problem of gdb seeing SIGILL rather than SIGTRAP when hitting
the KGDB special breakpoint upon SysRq+g being seen.  The problem was that
die_if_no_fixup() was failing to read the opcode of the instruction that caused
the exception, and thus not fixing up the exception.

This caused gdb to get a S04 response to the $? request in its remote protocol
rather than S05 - which would then cause it to continue with $C04 rather than
$c in an attempt to pass the signal onto the inferior process.  The kernel,
however, does not support $Cnn, and so objects by returning an E22 response,
indicating an error.  gdb does not expect this and prints:

	warning: Remote failure reply: E22

and then returns to the gdb command prompt unable to continue.
