Merge in keyrings fixes, at least some of which later patches depend on:
(1) Reinstate the production of EPERM for key types beginning with '.' in
requests from userspace.
(2) Tidy up the cleanup of PKCS#7 message signed information blocks and fix a
bug this made more obvious.

Fix the parser cleanup code to drain parsed out X.509 certs in the case that
the decode fails and we jump to error_decode.
The function is rearranged so that the same cleanup code is used in the success
case as the error case - just that the message descriptor under construction is
only released if it is still pointed to by the context struct at that point.

The code to free a signed info block is repeated several times, so move the
code to do it into a function of its own. This gives us a place to add clean
ups for stuff that gets added to pkcs7_signed_info.

Pull crypto fixes from Herbert Xu:
"This fixes the newly added drbg generator so that it actually works on
32-bit machines. Previously the code was only tested on 64-bit and on
32-bit it overflowed and simply doesn't work"
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: drbg - remove check for uninitialized DRBG handle
crypto: drbg - backport "fix maximum value checks on 32 bit systems"
|
|
Merging the crypto tree for 3.17 in order to resolve the conflict
on the 32-bit DRBG overflow fix.
|
|
The drbg_healthcheck() contained a test to call the DRBG with an
uninitialized DRBG cipher handle. As this is an inappropriate use of the
kernel crypto API to try to generate random numbers before
initialization, checks verifying for an initialized DRBG have been
removed in previous patches.
Now, the drbg_healthcheck test must also be removed.

On archs with PAGE_SIZE >= 64 KiB the function skcipher_alloc_sgl()
fails with -ENOMEM no matter what user space actually requested.
This is caused by the fact sock_kmalloc call inside the function tried
to allocate more memory than allowed by the default kernel socket buffer
size (kernel param net.core.optmem_max).

Relax the check on the length of the PKCS#7 cert as it appears that the PE
file wrapper size gets rounded up to the nearest 8.
The debugging output looks like this:
PEFILE: ==> verify_pefile_signature()
PEFILE: ==> pefile_parse_binary()
PEFILE: checksum @ 110
PEFILE: header size = 200
PEFILE: cert = 968 @547be0 [68 09 00 00 00 02 02 00 30 82 09 56 ]
PEFILE: sig wrapper = { 968, 200, 2 }
PEFILE: Signature data not PKCS#7
The wrapper is the first 8 bytes of the hex dump inside []. This indicates a
length of 0x968 bytes, including the wrapper header - so 0x960 bytes of
payload.
The ASN.1 wrapper begins [ ... 30 82 09 56 ]. That indicates an object of size
0x956 - a four byte discrepency, presumably just padding for alignment
purposes.
So we just check that the ASN.1 container is no bigger than the payload and
reduce the recorded size appropriately.
Whilst we're at it, allow shorter PKCS#7 objects that manage to squeeze within
127 or 255 bytes. It's just about conceivable if no X.509 certs are included
in the PKCS#7 message.

The lz4 library has two functions for decompression, with slightly
different signatures and behaviour. The lz4_decompress_crypto() function
seemed to be using the one that assumes that the decompressed length is
known in advance.
This patch switches to the other decompression function and makes sure
that the length of the decompressed output is properly returned to the
caller.
The same issue was present in the lz4hc algorithm.
Coincidentally, this change also makes very basic lz4 and lz4hc
compression tests in testmgr pass.

SP800-90A mandates several hard-coded values. The old drbg_cores allows
the setting of these values per DRBG implementation. However, due to the
hard requirement of SP800-90A, these values are now returned globally
for each DRBG.

The DRBG requires the conversion of an integer into a string
representation of that integer. The previous implementation converted
the given integer byte-wise. However, the kernel offers the cpu_to_be
function which already re-arranges the memory representation of an
integer such that it applies when interpreting the same memory as
character string.
The change therefore uses an integer-cast / union of the target
character array together with the cpu_to_be function to convert an
integer into its string representation.
Tests show that the Hash and CTR DRBG implementations (the HMAC DRBG
does not require such conversion) is about 10% faster (or requires less
computing power, respectively).

This patch introduces the multi-buffer crypto daemon which is responsible
for submitting crypto jobs in a work queue to the responsible multi-buffer
crypto algorithm. The idea of the multi-buffer algorihtm is to put
data streams from multiple jobs in a wide (AVX2) register and then
take advantage of SIMD instructions to do crypto computation on several
buffers simultaneously.
The multi-buffer crypto daemon is also responsbile for flushing the
remaining buffers to complete the computation if no new buffers arrive
for a while.

Now with 64bit bzImage and kexec tools, we support ramdisk that size is
bigger than 2g, as we could put it above 4G.
Found compressed initramfs image could not be decompressed properly. It
turns out that image length is int during decompress detection, and it
will become < 0 when length is more than 2G. Furthermore, during
decompressing len as int is used for inbuf count, that has problem too.
Change len to long, that should be ok as on 32 bit platform long is
32bits.
Tested with following compressed initramfs image as root with kexec.
gzip, bzip2, xz, lzma, lzop, lz4.

Pull ARM updates from Russell King:
"Included in this update:
- perf updates from Will Deacon:
The main changes are callchain stability fixes from Jean Pihet and
event mapping and PMU name rework from Mark Rutland
The latter is preparatory work for enabling some code re-use with
arm64 in the future.
- updates for nommu from Uwe Kleine-König:
Two different fixes for the same problem making some ARM nommu
configurations not boot since 3.6-rc1. The problem is that
user_addr_max returned the biggest available RAM address which
makes some copy_from_user variants fail to read from XIP memory.
- deprecate legacy OMAP DMA API, in preparation for it's removal.
The popular drivers have been converted over, leaving a very small
number of rarely used drivers, which hopefully can be converted
during the next cycle with a bit more visibility (and hopefully
people popping out of the woodwork to help test)
- more tweaks for BE systems, particularly with the kernel image
format. In connection with this, I've cleaned up the way we
generate the linker script for the decompressor.
- removal of hard-coded assumptions of the kernel stack size, making
everywhere depend on the value of THREAD_SIZE_ORDER.
- MCPM updates from Nicolas Pitre.
- Make it easier for proper CPU part number checks (which should
always include the vendor field).
- Assembly code optimisation - use the "bx" instruction when
returning from a function on ARMv6+ rather than "mov pc, reg".
- Save the last kernel misaligned fault location and report it via
the procfs alignment file.
- Clean up the way we create the initial stack frame, which is a
repeated pattern in several different locations.
- Support for 8-byte get_user(), needed for some DRM implementations.
- mcs locking from Will Deacon.
- Save and restore a few more Cortex-A9 registers (for errata
workarounds)
- Fix various aspects of the SWP emulation, and the ELF hwcap for the
SWP instruction.
- Update LPAE logic for pte_write and pmd_write to make it more
correct.
- Support for Broadcom Brahma15 CPU cores.
- ARM assembly crypto updates from Ard Biesheuvel"

Th AF_ALG socket was missing a security label (e.g. SELinux)
which means that socket was in "unlabeled" state.
This was recently demonstrated in the cryptsetup package
(cryptsetup v1.6.5 and later.)
See https://bugzilla.redhat.com/show_bug.cgi?id=1115120
This patch clones the sock's label from the parent sock
and resolves the issue (similar to AF_BLUETOOTH protocol family).

X.509 certificate issuer and subject fields are mandatory fields in the ASN.1
and so their existence needn't be tested for. They are guaranteed to end up
with an empty string if the name material has nothing we can use (see
x509_fabricate_name()).

pkcs7_request_asymmetric_key() and x509_request_asymmetric_key() do the same
thing, the latter being a copy of the former created by the IMA folks, so drop
the PKCS#7 version as the X.509 location is more general.
Whilst we're at it, rename the arguments of x509_request_asymmetric_key() to
better reflect what the values being passed in are intended to match on an
X.509 cert.

x509_request_asymmetric_keys() doesn't need the lengths of the NUL-terminated
strings passing in as it can work that out for itself.
