crypto, tcrypt: remove local_bh_disable/enable() around local_irq_disable/enable() · b6f3fefe

由 Suresh Siddha 提交于 9月 17, 2012

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. ]

crypto: talitos - fix icv management on outbound direction · 60542505

由 Horia Geanta 提交于 8月 02, 2012

For IPsec encryption, in the case when:
-the input buffer is fragmented (edesc->src_nents > 0)
-the output buffer is not fragmented (edesc->dst_nents = 0)
the ICV is not output in the link table, but after the encrypted payload.

Copying the ICV must be avoided in this case; consequently the condition
edesc->dma_len > 0 must be more specific, i.e. must depend on the type
of the output buffer - fragmented or not.

Testing was performed by modifying testmgr to support src != dst,
since currently native kernel IPsec does in-place encryption
(src == dst).
