<title>crypto: ctr - make rfc3686 asynchronous block cipher</title>

<id>69d3150cfc2075d1693d17dc711de61bf4e4a6c4</id>
<content type='text'>
Some hardware crypto drivers register asynchronous ctr(aes), which is left
unused in IPSEC because rfc3686 template only supports synchronous block
ciphers. Some other drivers register rfc3686(ctr(aes)) to workaround this
limitation but not all.

This patch changes rfc3686 to use asynchronous block ciphers, to allow async
ctr(aes) algorithms to be utilized automatically by IPSEC.

Most DES3_EDE testvectors are short and do not test parallelised codepaths
well. Add larger testvectors to test large crypto operations and to test
multi-page crypto with DES3_EDE.

<title>crypto, tcrypt: remove local_bh_disable/enable() around local_irq_disable/enable()</title>

<id>b6f3fefe1fa1e8ea8f6b654e7d552253373cd1c0</id>
<content type='text'>
Ran into this while looking at some new crypto code using FPU
hitting a WARN_ON_ONCE(!irq_fpu_usable()) in the kernel_fpu_begin()
on a x86 kernel that uses the new eagerfpu model. In short, current eagerfpu
changes return 0 for interrupted_kernel_fpu_idle() and the in_interrupt()
thinks it is in the interrupt context because of the local_bh_disable().
Thus resulting in the WARN_ON().

Remove the local_bh_disable/enable() calls around the existing
local_irq_disable/enable() calls. local_irq_disable/enable() already
disables the BH.

 [ If there are any other legitimate users calling kernel_fpu_begin() from
   the process context but with BH disabled, then we can look into fixing the
   irq_fpu_usable() in future. ]
