* crypto: caam - fix typo "CRYPTO_AHASH"Paul Bolle2013-03-101-1/+1
| | | | | | | | | | | | | 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.

* crypto: omap-aes - Use pm_runtime_put instead of pm_runtime_put_sync in taskletJoel A Fernandes2013-03-101-1/+1
| | | | | | | | | | | | | | | | | | | After DMA is complete, the omap_aes_finish_req function is called as a part of the done_task tasklet. During this its atomic and any calls to pm functions should not assume they wont sleep. The patch replaces a call to pm_runtime_put_sync (which can sleep) with pm_runtime_put thus fixing a kernel panic observed on AM33xx SoC during AES operation. Tested on an AM33xx SoC device (beaglebone board). To reproduce the problem, I used the tcrypt kernel module as: modprobe tcrypt sec=2 mode=500 Signed-off-by: Joel A Fernandes <joelagnel@ti.com> Cc: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three errors resulting in kernel memory disclosure: 1/ The structures used for the netlink based crypto algorithm report API are located on the stack. As snprintf() does not fill the remainder of the buffer with null bytes, those stack bytes will be disclosed to users of the API. Switch to strncpy() to fix this. 2/ crypto_report_one() does not initialize all field of struct crypto_user_alg. Fix this to fix the heap info leak. 3/ For the module name we should copy only as many bytes as module_name() returns -- not as much as the destination buffer could hold. But the current code does not and therefore copies random data from behind the end of the module name, as the module name is always shorter than CRYPTO_MAX_ALG_NAME. Also switch to use strncpy() to copy the algorithm's name and driver_name. They are strings, after all.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Note: The code being integrated is from the TI AM33xx SDK and was written by Greg Turner <gkmturner@gmail.com> and Herman Schuurman (current email unknown) while at TI.

| | | | | | | | | | | | | | | | | | | | The AES controller only needs to be reset once and that will be done by the hwmod infrastructure, if possible. Therefore, remove the reset code from the omap-aes driver. CC: Dmitry Kasatkin <dmitry.kasatkin@intel.com> Signed-off-by: Mark A.

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>
| * crypto: omap-sham - Add SHA224 and SHA256 SupportMark A. Greer2013-01-051-10/+173
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OMAP4/AM33xx version of the SHAM crypto module supports SHA224 and SHA256 in addition to MD5 and SHA1 that the OMAP2 version of the module supports. 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. Note: The code being integrated is from the TI AM33xx SDK and was written by Greg Turner <gkmturner@gmail.com> and Herman Schuurman (current email unknown) while at TI.
