d677124b1f rcu: Advise most users not to enable RCU user mode
Discourage distros from enabling CONFIG_RCU_USER_QS
because it brings overhead for no benefits yet.

It's not a useful feature on its own until we can
fully run an adaptive tickless kernel.

48ba2462ac MODSIGN: Implement module signature checking
Check the signature on the module against the keys compiled into the kernel or
available in a hardware key store.

Currently, only RSA keys are supported - though that's easy enough to change,
and the signature is expected to contain raw components (so not a PGP or
PKCS#7 formatted blob).

The signature blob is expected to consist of the following pieces in order:

 (1) The binary identifier for the key.  This is expected to match the
     SubjectKeyIdentifier from an X.509 certificate.  Only X.509 type
     identifiers are currently supported.

 (2) The signature data, consisting of a series of MPIs in which each is in
     the format of a 2-byte BE word sizes followed by the content data.

 (3) A 12 byte information block of the form:

	struct module_signature {
		enum pkey_algo		algo : 8;
		enum pkey_hash_algo	hash : 8;
		enum pkey_id_type	id_type : 8;
		u8			__pad;
		__be32			id_length;
		__be32			sig_length;
	};

     The three enums are defined in crypto/public_key.h.

     'algo' contains the public-key algorithm identifier (0->DSA, 1->RSA).

     'hash' contains the digest algorithm identifier (0->MD4, 1->MD5, 2->SHA1,
      etc.).

     'id_type' contains the public-key identifier type (0->PGP, 1->X.509).

     '__pad' should be 0.

     'id_length' should contain in the binary identifier length in BE form.

     'sig_length' should contain in the signature data length in BE form.

     The lengths are in BE order rather than CPU order to make dealing with
     cross-compilation easier.

ea0b6dcf71 MODSIGN: Provide Kconfig options
Provide kernel configuration options for module signing.

The following configuration options are added:

     CONFIG_MODULE_SIG_SHA1
     CONFIG_MODULE_SIG_SHA224
     CONFIG_MODULE_SIG_SHA256
     CONFIG_MODULE_SIG_SHA384
     CONFIG_MODULE_SIG_SHA512

These select the cryptographic hash used to digest the data prior to signing.
Additionally, the crypto module selected will be built into the kernel as it
won't be possible to load it as a module without incurring a circular
dependency when the kernel tries to check its signature.

106a4ee258 module: signature checking hook
We do a very simple search for a particular string appended to the module
(which is cache-hot and about to be SHA'd anyway).  There's both a config
option and a boot parameter which control whether we accept or fail with
unsigned modules and modules that are signed with an unknown key.

If module signing is enabled, the kernel will be tainted if a module is
loaded that is unsigned or has a signature for which we don't have the
key.

4520c6a49a X.509: Add simple ASN.1 grammar compiler
Add a simple ASN.1 grammar compiler.  This produces a bytecode output that can
be fed to a decoder to inform the decoder how to interpret the ASN.1 stream it
is trying to parse.

Action functions can be specified in the grammar by interpolating:

	({ foo })

after a type, for example:

	SubjectPublicKeyInfo ::= SEQUENCE {
		algorithm		AlgorithmIdentifier,
		subjectPublicKey	BIT STRING ({ do_key_data })
		}

The decoder is expected to call these after matching this type and parsing the
contents if it is a constructed type.

The grammar compiler does not currently support the SET type (though it does
support SET OF) as I can't see a good way of tracking which members have been
encountered yet without using up extra stack space.

Currently, the grammar compiler will fail if more than 256 bytes of bytecode
would be produced or more than 256 actions have been specified as it uses
8-bit jump values and action indices to keep space usage down.

046d662f48 coredump: make core dump functionality optional
Adds an expert Kconfig option, CONFIG_COREDUMP, which allows disabling of
core dump.  This saves approximately 2.6k in the compiled kernel, and
complements CONFIG_ELF_CORE, which now depends on it.

CONFIG_COREDUMP also disables coredump-related sysctls, except for
suid_dumpable and related functions, which are necessary for ptrace.

754b7b63d1 sections: disable const sections for PA-RISC v2
The PA-RISC tool chain seems to have some problem with correct
read/write attributes on sections.  This causes problems when the const
sections are fixed up for other architecture to only contain truly
read-only data.

Disable const sections for PA-RISC

This can cause a bit of noise with modpost.

437589a74b Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace changes from Eric Biederman:
 "This is a mostly modest set of changes to enable basic user namespace
  support.  This allows the code to code to compile with user namespaces
  enabled and removes the assumption there is only the initial user
  namespace.  Everything is converted except for the most complex of the
  filesystems: autofs4, 9p, afs, ceph, cifs, coda, fuse, gfs2, ncpfs,
  nfs, ocfs2 and xfs as those patches need a bit more review.

  The strategy is to push kuid_t and kgid_t values are far down into
  subsystems and filesystems as reasonable.  Leaving the make_kuid and
  from_kuid operations to happen at the edge of userspace, as the values
  come off the disk, and as the values come in from the network.
  Letting compile type incompatible compile errors (present when user
  namespaces are enabled) guide me to find the issues.

  The most tricky areas have been the places where we had an implicit
  union of uid and gid values and were storing them in an unsigned int.
  Those places were converted into explicit unions.  I made certain to
  handle those places with simple trivial patches.

  Out of that work I discovered we have generic interfaces for storing
  quota by projid.  I had never heard of the project identifiers before.
  Adding full user namespace support for project identifiers accounts
  for most of the code size growth in my git tree.

  Ultimately there will be work to relax privlige checks from
  "capable(FOO)" to "ns_capable(user_ns, FOO)" where it is safe allowing
  root in a user names to do those things that today we only forbid to
  non-root users because it will confuse suid root applications.

  While I was pushing kuid_t and kgid_t changes deep into the audit code
  I made a few other cleanups.  I capitalized on the fact we process
  netlink messages in the context of the message sender.  I removed
  usage of NETLINK_CRED, and started directly using current->tty.

  Some of these patches have also made it into maintainer trees, with no
  problems from identical code from different trees showing up in
  linux-next.

  After reading through all of this code I feel like I might be able to
  win a game of kernel trivial pursuit."

Fix up some fairly trivial conflicts in netfilter uid/git logging code.

fdf9c35650 cputime: Make finegrained irqtime accounting generally available
There is no known reason for this option to be unavailable on other
archs than x86. They just need to call enable_sched_clock_irqtime()
if they have a sufficiently finegrained clock to make it working.

Move it to the general option and let the user choose between
it and pure tick based or virtual cputime accounting.

Note that virtual cputime accounting already performs a finegrained
irqtime accounting. CONFIG_IRQ_TIME_ACCOUNTING is a kind of middle ground
between tick and virtual based accounting. So CONFIG_IRQ_TIME_ACCOUNTING
and CONFIG_VIRT_CPU_ACCOUNTING are mutually exclusive choices.
