This patch disables the authenc tests while the conversion to the new IV calling convention takes place. It also replaces the authenc test vectors with ones that will work with the new IV convention. Signed-off-by:Herbert Xu <herbert@gondor.apana.org.au>

Compiling the talitos driver with my GCC 4.3.1 e500v2 cross-compiler resulted in a failed build due to the anonymous union/structures introduced in this commit: crypto: talitos - enhanced talitos_desc struct for SEC1 The build error was: drivers/crypto/talitos.h:56: error: unknown field 'len' specified in initializer drivers/crypto/talitos.h:56: warning: missing braces around initializer drivers/crypto/talitos.h:56: warning: (near initialization for 'zero_entry.<anonymous>') drivers/crypto/talitos.h:57: error: unknown field 'j_extent' specified in initializer drivers/crypto/talitos.h:58: error: unknown field 'eptr' specified in initializer drivers/crypto/talitos.h:58: warning: excess elements in struct initializer drivers/crypto/talitos.h:58: warning: (near initialization for 'zero_entry') make[2]: *** [drivers/crypto/talitos.o] Error 1 make[1]: *** [drivers/crypto] Error 2 make: *** [drivers] Error 2 This patch eliminates the errors by relying on the C standard's implicit assignment of zero to static variables.

The encap shared descriptor was changed to use the new IV convention. In the process some commands were shifted, making the output length zero, caam effectively writing garbage in dst. While here, update the decap descriptor to execute the "write" commands before the "read"s (as it previously was). This makes sure the input fifo is drained before becoming full. Fixes: 46218750 ("crypto: caam - Use new IV convention") Signed-off-by:

Return success instead of error if compression succeeds but the output is larger than the input. It's unlikely that the caller will use the compressed data since it's larger than the original uncompressed data, but there was no error and returning an error code is incorrect. Further, for testing small input buffers, the output is likely to be larger than the input and success needs to be returned to verify the test. Signed-off-by:

The kthread_run() function can return two different error values but the hwrng core only checks for -ENOMEM. If the other error value -EINTR is returned it is assigned to hwrng_fill and later used on a kthread_stop() call which naturally crashes. Cc: stable@vger.kernel.org Signed-off-by:

Remove the common 'platform' registration module, and move the crypto compression driver registration into each of the pSeries and PowerNV platform NX 842 drivers. Change the nx-842.c code into simple common functions that each platform driver uses to perform constraints-based buffer changes, i.e. realigning and/or resizing buffers to match the driver's hardware requirements. The common 'platform' module was my mistake to create - since each platform driver will only load/operate when running on its own platform (i.e. a pSeries platform or a PowerNV platform), they can directly register with the crypto subsystem, using the same alg and driver name. This removes unneeded complexity. Signed-off-by:

The last commit merged nx-842.c's code into nx-842-crypto.c. It did not rename nx-842-crypto.c to nx-842.c, in order to let the patch more clearly show what was merged. This just renames nx-842-crypto.c to nx-842.c, with no changes to its code. Signed-off-by:

Merge the nx-842.c code into nx-842-crypto.c. This allows later patches to remove the 'platform' driver, and instead allow each platform driver to directly register with the crypto compression api. Signed-off-by:

Replace the duplicated finishing code (set destination buffer length and set return code to 0) in the case of decompressing a buffer with no header with a goto to the success case of decompressing a buffer with a header. This is a trivial change that allows both success cases to use common code, and includes the pr_debug() msg in both cases as well. Signed-off-by:

Don't register the pSeries driver when parsing the device tree returns ENODEV. The nx842_probe() function in the pSeries driver returns error instead of registering as a crypto compression driver, when it receives an error return value from the nx842_OF_upd() function that probes the device tree nodes, except when ENODEV is returned. However ENODEV should not be a special case and the driver should not register when there is no hw device, or the hw device is disabled. Signed-off-by:

Move the kzalloc() calls in nx842_probe() and nx842_OF_upd() to the top of the functions, before taking the devdata spinlock. Since kzalloc() without GFP_ATOMIC can sleep, it can't be called while holding a spinlock. Move the calls to before taking the lock. Signed-off-by:

Remove the 'status' field from the pSeries NX driver data. The 'status' field isn't used by the driver at all; it simply checks the devicetree status node at initialization, and returns success if 'okay' and failure otherwise. Signed-off-by:

HW coherency won't work properly for CAAM write transactions if AWCACHE is left to default (POR) value - 4'b0001. It has to be programmed to 4'b0010, i.e. AXI3 Cacheable bit set. For platforms that have HW coherency support: -PPC-based: the update has no effect; CAAM coherency already works due to the IOMMU (PAMU) driver setting the correct memory coherency attributes -ARM-based: the update fixes cache coherency issues, since IOMMU (SMMU) driver is not programmed to behave similar to PAMU Signed-off-by:
