2011-11-01crypto: add module.h to those files that are explicitly using itPaul Gortmaker1-0/+1
Part of the include cleanups means that the implicit inclusion of module.h via device.h is going away. So fix things up in advance. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-10-21crypto: talitos - handle descriptor not found in error pathKim Phillips1-8/+10
The CDPR (Current Descriptor Pointer Register) can be unreliable when trying to locate an offending descriptor. Handle that case by (a) not OOPSing, and (b) reverting to the machine internal copy of the descriptor header in order to report the correct execution unit error. Note: printing all execution units' ISRs is not effective because it results in an internal time out (ITO) error and the EU resetting its ISR value (at least when specifying an invalid key length on an SEC 2.2/MPC8313E).

Use a platform ID table and a single platform_driver. It's neater and makes the device tree addition easier and more consistent.

2011-08-03crypto: padlock-aes - Make module loading even quieter when hardware is missingJonathan Nieder1-3/+1
When loading aes via the module alias, a padlock module failing to load due to missing hardware is not particularly notable. With v2.6.27-rc1~1107^2~14 (crypto: padlock - Make module loading quieter when hardware isn't available, 2008-07-03), the padlock-aes module suppresses the relevant messages when the "quiet" flag is in use; but better to suppress this particular message completely, since the administrator can already distinguish such errors by the absence of a message indicating initialization failing or succeeding. This avoids occasional messages in syslog of the form padlock_aes: VIA PadLock not detected.

A small modification was necessary since in the machine description for 'n2cp' and 'ncp' nodes, there no longer is an 'intr' property. That's OK because this property was always nothing more than an array of integers '1' ... 'nr_inos + 1' so we can just compute it in-place. Signed-off-by: David S. Miller <davem@davemloft.net>

2011-07-15crypto: talitos - ensure request ordering within a single tfmKim Phillips1-9/+14
Assign single target channel per tfm in talitos_cra_init instead of performing channel scheduling dynamically during the encryption request. This changes the talitos_submit interface to accept a new channel number argument. Without this, rapid bursts of misc. sized requests could make it possible for IPsec packets to be encrypted out-of-order, which would result in packet drops due to sequence numbers falling outside the anti-reply window on a peer gateway.

The Security function on the AMCC SoCs has multiple engines within a single MMIO range. The crypto driver currently enables the 3DES functionality by doing a blind write to the device control register. This can unintentionally disable other functions like the PKA or TRNG when the driver is loaded. Perform a read/modify/write to enable the 3DES function instead.

2011-06-30crypto: omap-sham - irq and dma handling changesDmitry Kasatkin1-13/+27
It could be a situation, that tasklet is executed twice because of certain delay between dma callback and irq handler execution.

2011-06-30crypto: omap-sham - remove dedicated queue handling taskletDmitry Kasatkin1-15/+9
Calling omap_sham_handle_queue from "done" tasklet should be done after irq scheduled tasklet completes. Having additional tasklet does not solve that issue because it might be execute before.

In doing so, sha512 sized keys would not fit with the current descriptor inlining mechanism, so we now calculate whether keys should be referenced instead by pointers in the shared descriptor. also, use symbols for descriptor text lengths, and, ahem, unmap and free key i/o memory in cra_exit.

2011-05-19crypto: caam - fix decryption shared vs. non-shared key settingKim Phillips1-4/+22
Key sharing is enabled by default in the shared descriptor. Using CBC decrypt, AES has to alter the key in order to decrypt. During high traffic decryption rates, i.e, when sharing starts to take place, we need to use a different OPERATION option to tell AES that the key was already altered by the PRIOR descriptor - we need the following kind of logic: if ( shared ) operation where AES uses decryption key (DK=1) else operation where AES uses encryption key (DK=0) this patch implements this logic using a conditional and a non-conditional local jump within the decryption job descriptor.
