Instead of always creating a huge (268K) deflate_workspace with the
maximum compression parameters (windowBits=15, memLevel=8), allow the
caller to obtain a smaller workspace by specifying smaller parameter
values.For example, when capturing oops and panic reports to a medium with
limited capacity, such as NVRAM, compression may be the only way to
capture the whole report. In this case, a small workspace (24K works
fine) is a win, whether you allocate the workspace when you need it (i.e.,
during an oops or panic) or at boot time.I've verified that this patch works with all accepted values of windowBits
(positive and negative), memLevel, and compression level.Signed-off-by: Jim Keniston

A self-test failure in fips mode means a panic. Well, gcm(aes)
self-tests currently fail in fips mode, as gcm is dependent on ghash,
which semi-recently got self-test vectors added, but wasn't marked as a
fips_allowed algorithm. Because of gcm's dependence on what is now seen
as a non-fips_allowed algorithm, its self-tests refuse to run.
Previously, ghash got a pass in fips mode, due to the lack of any test
vectors at all, and thus gcm self-tests were able to run. After this
patch, a 'modprobe tcrypt mode=35' no longer panics in fips mode, and
successful self-test of gcm(aes) is reported.Signed-off-by: Jarod Wilson

We (Red Hat) are intending to include dm-crypt functionality, using
xts(aes) for disk encryption, as part of an upcoming FIPS-140-2
certification effort, and xts(aes) *is* on the list of possible
mode/cipher combinations that can be certified. To make that possible, we
need to mark xts(aes) as fips_allowed in the crypto subsystem.A 'modprobe tcrypt mode=10' in fips mode shows xts(aes) self-tests
passing successfully after this change.Signed-off-by: Jarod Wilson

kcrypto_wq and pcrypt->wq's are used to run ciphers and may consume
considerable amount of CPU cycles. Mark both as CPU_INTENSIVE so that
they don't block other work items.As the workqueues are primarily used to burn CPU cycles, concurrency
levels shouldn't matter much and are left at 1. A higher value may be
beneficial and needs investigation.Signed-off-by: Tejun Heo

As it is if user-space passes through a receive buffer that's not
aligned to to the cipher block size, we'll end up encrypting or
decrypting a partial block which causes a spurious EINVAL to be
returned.This patch fixes this by moving the partial block test after the
af_alg_make_sg call.Signed-off-by: Herbert Xu

When sk_sndbuf is not a multiple of PAGE_SIZE, the limit tests
in sendmsg fail as the limit variable becomes negative and we're
using an unsigned comparison.The same thing can happen if sk_sndbuf is lowered after a sendmsg
call.This patch fixes this by always taking the signed maximum of limit
and 0 before we perform the comparison.It also rounds the value of sk_sndbuf down to a multiple of PAGE_SIZE
so that we don't end up allocating a page only to use a small number
of bytes in it because we're bound by sk_sndbuf.Signed-off-by: Herbert Xu

The AES-NI instructions are also available in legacy mode so the 32-bit
architecture may profit from those, too.To illustrate the performance gain here's a short summary of a dm-crypt
speed test on a Core i7 M620 running at 2.67GHz comparing both assembler
implementations:x86: i568 aes-ni delta
ECB, 256 bit: 93.8 MB/s 123.3 MB/s +31.4%

XTS, 256 bit: 105.0 MB/s 205.5 MB/s +95.7%Additionally, due to some minor optimizations, the 64-bit version also
got a minor performance gain as seen below:x86-64: old impl. new impl. delta

This patch adds the af_alg plugin for symmetric key ciphers,
corresponding to the ablkcipher kernel operation type.Keys can optionally be set through the setsockopt interface.
Once a sendmsg call occurs without MSG_MORE no further writes
may be made to the socket until all previous data has been read.IVs and and whether encryption/decryption is performed can be
set through the setsockopt interface or as a control message
to sendmsg.The interface is completely synchronous, all operations are
carried out in recvmsg(2) and will complete prior to the system
call returning.The splice(2) interface support reading the user-space data directly
without copying (except that the Crypto API itself may copy the data
if alignment is off).The recvmsg(2) interface supports directly writing to user-space
without additional copying, i.e., the kernel crypto interface will
receive the user-space address as its output SG list.Thakns to Miloslav Trmac for reviewing this and contributing
fixes and improvements.Signed-off-by: Herbert Xu

This patch adds the af_alg plugin for hash, corresponding to
the ahash kernel operation type.Keys can optionally be set through the setsockopt interface.
Each sendmsg call will finalise the hash unless sent with a MSG_MORE
flag.Partial hash states can be cloned using accept(2).
The interface is completely synchronous, all operations will
complete prior to the system call returning.Both sendmsg(2) and splice(2) support reading the user-space
data directly without copying (except that the Crypto API itself
may copy the data if alignment is off).For now only the splice(2) interface supports performing digest
instead of init/update/final. In future the sendmsg(2) interface
will also be modified to use digest/finup where possible so that
hardware that cannot return a partial hash state can still benefit
from this interface.Thakns to Miloslav Trmac for reviewing this and contributing
fixes and improvements.Signed-off-by: Herbert Xu

This patch creates the backbone of the user-space interface for
the Crypto API, through a new socket family AF_ALG.Each session corresponds to one or more connections obtained from
that socket. The number depends on the number of inputs/outputs
of that particular type of operation. For most types there will
be a s ingle connection/file descriptor that is used for both input
and output. AEAD is one of the few that require two inputs.Each algorithm type will provide its own implementation that plugs
into af_alg. They're keyed using a string such as "skcipher" or
"hash".IOW this patch only contains the boring bits that is required
to hold everything together.Thakns to Miloslav Trmac for reviewing this and contributing

I noticed that by factoring out common rounds from the
branches of the if-statements in the encryption and
decryption functions, the executable file size goes down
significantly, for crypto/cast5.ko from 26688 bytes
to 24336 bytes (amd64).On my test system, I saw a slight speedup. This is the
first time I'm doing such a benchmark - I found a similar
one on the crypto mailing list, and I hope I did it right?Before:
