hwrng: tx4939 - simplify use of devm_ioremap_resource · 9dc48034

由 Julia Lawall 提交于 8月 14, 2013

Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.

Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.

A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;
@@

- res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  ... when != res
- if (res == NULL) { ... \(goto l;\|return ret;\) }
  ... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
  e = devm_ioremap_resource(e1, res);
// </smpl>

crypto: nx - fix concurrency issue · c849163b

由 Marcelo Cerri 提交于 8月 12, 2013

The NX driver uses the transformation context to store several fields
containing data related to the state of the operations in progress.
Since a single tfm can be used by different kernel threads at the same
time, we need to protect the data stored into the context.

This patch makes use of spin locks to protect the data where a race
condition can happen.

crypto: nx - saves chaining value from co-processor · cc76daf7

由 Fionnuala Gunter 提交于 8月 07, 2013

This patch fixes a bug that is triggered when cts(cbc(aes)) is used with
nx-crypto driver on input larger than 32 bytes.

The chaining value from co-processor was not being saved. This value is
needed because it is used as the IV by cts(cbc(aes)).
