2013-05-24drivers/crypto/nx: Fixes for multiple races and issuesKent Yoder6-38/+19
Fixes a race on driver init with registering algorithms where the driver status flag wasn't being set before self testing started. Added the cra_alignmask field for CBC and ECB modes. Fixed a bug in GCM where AES block size was being used instead of authsize. Removed use of blkcipher_walk routines for scatterlist processing. Corner cases in the code prevent us from processing an entire scatterlist at a time and walking the buffers in block sized chunks turns out to be unecessary anyway. Fixed off-by-one error in saving off extra data in the sha code. Fixed accounting error for number of bytes processed in the sha code.

2013-04-25crypto: caam - fix job ring cleanup codeVakul Garg2-0/+5
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 Garg2-1/+6
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.

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.

2013-01-20crypto: omap-aes - Add CTR algorithm SupportMark A. Greer1-15/+128
The OMAP3 and OMAP4/AM33xx versions of the AES crypto module support the CTR algorithm in addition to ECB and CBC that the OMAP2 version of the module supports. So, OMAP2 and OMAP3 share a common register set but OMAP3 supports CTR while OMAP2 doesn't. OMAP4/AM33XX uses a different register set from OMAP2/OMAP3 and also supports CTR. To add this support, use the platform_data introduced in an ealier commit to hold the list of algorithms supported by the current module. The probe routine will use that list to register the correct algorithms.

2013-01-20crypto: omap-aes - Add OMAP4/AM33XX AES SupportMark A. Greer1-33/+125
Add support for the OMAP4 version of the AES module that is present on OMAP4 and AM33xx SoCs. The modules have several differences including register offsets and how DMA is triggered. To handle these differences, a platform_data structure is defined and contains routine pointers, register offsets, and bit offsets within registers. OMAP2/OMAP3-specific routines are suffixed with '_omap2' and OMAP4/AM33xx routines are suffixed with '_omap4'.

2013-01-20crypto: bfin_crc - reposition free_irq to avoid access to invalid dataJulia Lawall1-3/+3
The data referenced by an interrupt handler should not be freed before the interrupt is ended. The handler is bfin_crypto_crc_handler. It may refer to crc->regs, which is released by the iounmap. Furthermore, the second argument to all calls to free_irq is incorrect. It should be the same as the last argument of request_irq, which is crc, rather than crc->dev. The semantic match that finds the first problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @fn exists@ expression list es; expression a,b; identifier f; @@ if (...) { ... when any free_irq(a,b); ... when any f(es); ... when any return ...; } @@ expression list fn.es; expression fn.a,fn.b; identifier fn.f; @@ *f(es); ... when any *free_irq(a,b); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2013-01-11ARM: OMAP2+: Disable code that currently does not work with multiplaformTony Lindgren1-0/+3
We still need to fix up few places for multiplatform support, but that can proceed separately. Fix the issue by making the problem drivers depends !ARCH_MULTIPLATFORM for now. The remaining pieces that are not multiplatform compatible for omap2+ SoCs are: 1. Some drivers are using custom omap_dm_timer calls There are two drivers that are directly usign omap hardware timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and drivers/staging/tidspbridge/core/dsp-clock.c. These can be fixed for multiplatform by allowing a minimal set of hardware timers to be accessed, and for some functionality by using the hrtimer framework. 2. Hardware OMAP4_ERRATA_I688 needs to be fixed up This can't be enabled for multiplatform configurations in it's current form. It may be possible to fix it up to do instruction replacement early on during init. Luckily it looks like this errata does not seem to get hit with mainline kernel code alone at least currently. 3. Legacy header needed for omap-sham.c Looks like it still needs mach/irqs.h for omap1 that does not exist for multiplatform systems. Just ifdef it for now. 4. Mailbox is waiting to get moved to drivers Disable it for now to avoid adding a dependency to the mailbox patches.
