The AF_ALG socket family is the userspace interface for linux
crypto API, users can use it to access hardware accelerators.
This patchset adds a afalg-backend for qemu crypto subsystem. Currently
when performs encrypt/decrypt, we'll try afalg-backend first and will
back to libiary-backend if it failed.
In the next step, It would support a command parameter to specifies
which backends prefer to and some other improvements.
I measured the performance about the afalg-backend impls, I tested
how many data could be encrypted in 5 seconds.
NOTE: If we use specific hardware crypto cards, I think afalg-backend
would even faster.
test-environment: Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz

Changes since v1:
- init sockaddr_alg object when it's defined. [Gonglei]
- fix some superfluous initialization. [Gonglei]
- s/opeartion/operation/g in crypto/afalgpriv.h. [Gonglei]
- check 'niv' in qcrypto_afalg_cipher_setiv. [Gonglei]
Changes since v1:
- use "make check-speed" to testing the performance. [Daniel]
- put private definations into crypto/***priv.h. [Daniel]
- remove afalg socket from qapi-schema, put them into crypto/. [Daniel]
- some Error report change. [Daniel]
- s/QCryptoAfalg/QCryptoAFAlg. [Daniel]
- use snprintf with bounds checking instead of sprintf. [Daniel]
- use "qcrypto_afalg_" prefix and "qcrypto_nettle(gcrypt,glib,builtin)_" prefix. [Daniel]
- add testing results in cover-letter. [Gonglei]

Refactors the qcrypto_cipher_free(), splits it into two parts. One
is gcrypt/nettle__cipher_free_ctx() to free the special context.
This makes code more clear, what's more, it would be used by the
later patch.

ctx->handle if gcry_mac_setkey fails.
2) Extracts qcrypto_hmac_ctx_new() from qcrypto_hmac_new() for
gcrypt-backend impls.

1) makes the public APIs in hmac-nettle/gcrypt/glib static,
and rename them with "nettle/gcrypt/glib" prefix.
2) introduces hmac framework, including QCryptoHmacDriver
and new public APIs.

The AF_ALG socket family is the userspace interface for linux
crypto API, this patch adds af_alg family support and some common
functions for af_alg backend. It'll be used by afalg-backend crypto
latter.

Adds afalg-backend hmac support: introduces some private APIs
firstly, and then intergrates them into qcrypto_hmac_afalg_driver.

Now we have two qcrypto backends, libiary-backend and afalg-backend,
but which one is faster? This patch add a cipher speed benchmark, it
helps us to measure the performance by using "make check-speed" or
using "./tests/benchmark-crypto-cipher" directly.

This patch add a hmac speed benchmark, it helps us to
measure the performance by using "make check-speed" or
using "./tests/benchmark-crypto-hmac" directly.

This is uneccessarily complicated - we can just use
if (strlen(name) >= SALG_NAME_LEN_MAX) {
....

Rather than indenting the entire method it is preferrable to
invert the condition and return immediately, eg
if (!afalg) {
return;

Using g_new0+snprintf() is never a good idea. Instead use g_strdup_printf().
There is no need for the length check here either, since
qcrypto_afalg_comm_alloc() is already going to bounds check
it

IMHO whether we use afalg or not should be hidden from users of the
crypto API, so I'd prefer we didn't add this method

This looks wierd - we should not have different behaviour here when
using afalg

Again use g_strdup_printf() and don't check length here.

If ret != 0, then 'errp' would have been set to an error. At
least we needs to be free'd before we call into the next driver.
I also wonder if we should treat some afalg errors as fatal

Hi Daniel，
First, sorry for the long delay...
I have modified the code as your suggestion, and I'll send V4 soon.
