* crypto: talitos - dma_map_sg can handle chained SGLABBE Corentin2015-10-011-86/+18
| | | | | | | | | | | | | The talitos driver use two dma_map_sg path according to SG are chained or not. Since dma_map_sg can handle both case, clean the code with all references to sg chained. Thus removing talitos_map_sg, talitos_unmap_sg_chain and sg_count functions. Signed-off-by: LABBE Corentin <clabbe.montjoie@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* | crypto: talitos - Prevent panic in probe error pathAaron Sierra2015-08-101-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Revert "crypto: talitos - convert to use be16_add_cpu()"Horia Geant?2015-05-131-1/+2
| | | | | | | | | | | | | This reverts commit 7291a932c6e27d9768e374e9d648086636daf61c. The conversion to be16_add_cpu() is incorrect in case cryptlen is negative due to premature (i.e. before addition / subtraction) implicit conversion of cryptlen (int -> u16) leading to sign loss.

* crypto: talitos - implement scatter/gather copy for SEC1LEROY Christophe2015-04-211-37/+101
| | | | | | | | | | | | | | SEC1 doesn't support scatter/gather, SEC1 doesn't handle link tables. Therefore, for SEC1 we have to do it by SW. For that, we reserve space at the end of the extended descriptor, in lieu of the space reserved for the link tables on SEC2, and we perform sg_copy() when preparing the descriptors We also adapt the max buffer size which is only 32k on SEC1 while it is 64k on SEC2+ Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: talitos - adapt interrupts and reset functions to SEC1LEROY Christophe2015-04-211-55/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adapts the interrupts handling and reset function for SEC1. On SEC1, registers are almost similar to SEC2+, but bits are sometimes located at different places. So we need to define TALITOS1 and TALITOS2 versions of some fields, and manage according to whether it is SEC1 or SEC2. On SEC1, only one interrupt vector is dedicated to the SEC, so only interrupt_4ch is needed. On SEC1, interrupts are enabled by clearing related bits in IMR, while on SEC2, interrupts are enabled by seting the bits in IMR. SEC1 also performs parity verification in the DES Unit. We have to disable this feature because the test vectors provided in the kernel have parity errors. In reset functions, only SEC2 supports continuation after error. For SEC1, we have to reset in all cases. For errors handling, SEC2+ names have been kept, but displayed text have been amended to reflect exact meaning on SEC1.

* Revert "crypto: talitos - add IPsec ESN support"Horia Geanta2013-03-211-28/+2
| | | | | | | | | | | | | | | | | | | This reverts commit e763eb699be723fb41af818118068c6b3afdaf8d. Current IPsec ESN implementation for authencesn(cbc(aes), hmac(sha)) (separate encryption and integrity algorithms) does not conform to RFC4303. ICV is generated by hashing the sequence SPI, SeqNum-High, SeqNum-Low, IV, Payload instead of SPI, SeqNum-Low, IV, Payload, SeqNum-High.

* crypto: talitos - fix icv management on outbound directionHoria Geanta2012-08-281-1/+1
| | | | | | | | | | | | | | | | | | 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).
