* crypto: nx - Removing CTR mode from NX driverLeonidas Da Silva Barbosa2015-08-103-30/+1Star
| | | | | | | | | | | CTR hardware implementation does not match with kernel spec causing a counter bug where just low 8 bytes are used for counter, when should be all 16bytes. Since we already have other counter modes working according with specs not worth to keep CTR itself on NX. Signed-off-by: Leonidas S.

| | | | | | | | | | | | The PCI capabilities list for Intel DH895xCC VFs (device id 0x0443) with QuickAssist Technology is prematurely terminated in hardware.

* crypto: talitos - Prevent panic in probe error pathAaron Sierra2015-08-102-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The probe error path for this driver, for all intents and purposes, is the talitos_remove() function due to the common "goto err_out". Without this patch applied, talitos_remove() will panic under these two conditions: 1. If the RNG device hasn't been registered via talitos_register_rng() prior to entry into talitos_remove(), then the attempt to unregister the RNG "device" will cause a panic. 2. If the priv->chan array has not been allocated prior to entry into talitos_remove(), then the per-channel FIFO cleanup will panic because of the dereference of that NULL "array". Both of the above scenarios occur if talitos_probe_irq() fails. This patch resolves issue #1 by introducing a boolean to mask the hwrng_unregister() call in talitos_unregister_rng() if RNG device registration was unsuccessful. It resolves issue #2 by checking that priv->chan is not NULL in the per-channel FIFO cleanup for loop.
