2013-11-28crypto: caam - fix aead sglen for case 'dst != src'Horia Geanta
For aead case when source and destination buffers are different, there is an incorrect assumption that the source length includes the ICV length.

The SEC Job Rings are now available as individual devices. This would enable sharing of job rings between kernel and user space. Job Rings can now be dynamically bound/unbound from kernel. Changes are made in the following layers of CAAM Driver 1. Controller driver - Does basic initialization of CAAM Block. - Creates platform devices for Job Rings.

2013-09-13crypto: caam - enable instantiation of all RNG4 state handlesAlex Porosanu
RNG4 block contains multiple (i.e. 2) state handles that can be initialized. This patch adds the necessary code for detecting which of the two state handles has been instantiated by another piece of software e.g. u-boot and instantiate the other one (or both if none was instantiated). Only the state handle(s) instantiated by this driver will be deinstantiated when removing the module.

2013-09-13crypto: caam - split RNG4 instantiation functionAlex Porosanu
This patch splits the RNG4 state handle instantiation function into two parts: one that handles the creation of the descriptor which instructs the CAAM to perform the instantiation of the state handle and another function that performs the running of the said descriptor using the DECO debug mechanism.

2013-09-13crypto: caam - fix RNG4 instantiationAlex Porosanu
The RNG4 block in CAAM needs to be 'seeded' first before being used for generating pseudo-random data. The 'seeding' is done by getting entropy from the TRNG ring oscillator. The RTFRQMAX register controls the maximum allowable number of samples that can be aquired during an entropy sample. Depending on the clock at which the RNG4 block (and for that matter the SEC block) runs, it's possible that a hard-coded value for the maximum frequency is inadequate, i.e. more samples than needed are taken. This is an error, and thus the RNG4 block doesn't get initialized. The patch attempts to alleviate this issue by trying with progressivly larger frequencies, until the number of samples is adequate. This patch also fixes how a descriptor is deemed as being finished: instead of checking the VALID field in the DECO debug register, it makes sure that the DECO is idle, by checking the DECO state field of the said register.

2013-09-13crypto: caam - fix RNG state handle instantiation descriptorAlex Porosanu
The way the DECO runs a descriptor through the direct (debug) interface is different from the JRI interface: the DECO will continue to try and execute the next commands, after the descriptor buffer has ended. This leads to unpredictable results and possibly to locking up of the DECO. This patch adds a halt command at the end of the descriptor to ensure the DECO halts when it reaches the end of the descriptor buffer.

For SEC including a RNG block version >= 4, special initialization must occur before any descriptor that uses RNG block can be submitted. This initialization is required not only for SEC with version greater than 5.0, but for SEC with RNG version >=4. There may be a case where RNG has already been instantiated by u-boot or boot ROM code.In such SoCs, if RNG is initialized again SEC would returns "Instantiation error". Hence, the initialization status of RNG4 should be also checked before doing RNG init.

2013-04-25crypto: caam - fix job ring cleanup codeVakul Garg
The job ring init function creates a platform device for each job ring. While the job ring is shutdown, e.g. while caam module removal, its platform device was not being removed. This leads to failure while reinsertion and then removal of caam module second time. The following kernel crash dump appears when caam module is reinserted and then removed again. This patch fixes it. root@p4080ds:~# rmmod caam.ko Unable to handle kernel paging request for data at address 0x00000008 Faulting instruction address: 0xf94aca18 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=8 P4080 DS Modules linked in: caam(-) qoriq_dbg(O) [last unloaded: caam] NIP: f94aca18 LR: f94aca18 CTR: c029f950 REGS: eac47d60 TRAP: 0300 Tainted: G O (3.8.4-rt2) MSR: 00029002 <CE,EE,ME> CR: 22022484 XER: 20000000 DEAR: 00000008, ESR: 00000000 TASK = e49dfaf0[2110] 'rmmod' THREAD: eac46000 CPU: 1 GPR00: f94ad3f4 eac47e10 e49dfaf0 00000000 00000005 ea2ac210 ffffffff 00000000 GPR08: c286de68 e4977ce0 c029b1c0 00000001 c029f950 10029738 00000000 100e0000 GPR16: 00000000 10023d00 1000cbdc 1000cb8c 1000cbb8 00000000 c07dfecc 00000000 GPR24: c07e0000 00000000 1000cbd8 f94e0000 ffffffff 00000000 ea53cd40 00000000 NIP [f94aca18] caam_reset_hw_jr+0x18/0x1c0 [caam] LR [f94aca18] caam_reset_hw_jr+0x18/0x1c0 [caam] Call Trace: [eac47e10] [eac47e30] 0xeac47e30 (unreliable) [eac47e20] [f94ad3f4] caam_jr_shutdown+0x34/0x220 [caam] [eac47e60] [f94ac0e4] caam_remove+0x54/0xb0 [caam] [eac47e80] [c029fb38] __device_release_driver+0x68/0x120 [eac47e90] [c02a05c8] driver_detach+0xd8/0xe0 [eac47eb0] [c029f8e0] bus_remove_driver+0xa0/0x110 [eac47ed0] [c00768e4] sys_delete_module+0x144/0x270 [eac47f40] [c000e2f0] ret_from_syscall+0x0/0x3c Signed-off-by: Vakul Garg <vakul@freescale.com> Signed-off-by: Bharat Bhushan <bharat.bhushan@freescale.com> Reviewed-by: Horia Geanta <horia.geanta@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2013-03-22crypto: caam - set RDB bit in security configuration registerVakul Garg
This change is required for post SEC-5.0 devices which have RNG4. Setting RDB in security configuration register allows CAAM to use the "Random Data Buffer" to be filled by a single request. The Random Data Buffer is large enough for ten packets to get their IVs from a single request. If the Random Data Buffer is not enabled, then each IV causes a separate request, and RNG4 hardware cannot keep up resulting in lower IPSEC throughput if random IVs are used.

This reverts commit 891104ed008e8646c7860fe5bc70b0aac55dcc6c. 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.

The Kconfig entry for CAAM's hash algorithm implementations has always selected CRYPTO_AHASH. But there's no corresponding Kconfig symbol. It seems it was intended to select CRYPTO_HASH, like other crypto drivers do. That would apparently (indirectly) select CRYPTO_HASH2, which would enable the ahash functionality this driver uses.

2013-01-03Drivers: crypto: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
