* crypto: ux500 - add missing commaLinus Walleij2013-04-05
| | | | | | | | | | | | | | | | | | Commit 4f31f5b19eb0418a847b989abc9ac22af1991fe2 "PM / crypto / ux500: Use struct dev_pm_ops for power management" add a new line to the driver struct but missed to add a trailing comma, causing build errors when crypto is selected. This adds the missing comma. This was not noticed until now because the crypto block is not in the ux500 defconfig. A separate patch will be submitted to fix this.

* crypto: gcm - fix assumption that assoc has one segmentJussi Kivilinna2013-04-02
| | | | | | | | | | | | | rfc4543(gcm(*)) code for GMAC assumes that assoc scatterlist always contains only one segment and only makes use of this first segment. However ipsec passes assoc with three segments when using 'extended sequence number' thus in this case rfc4543(gcm(*)) fails to function correctly. Patch fixes this issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * crypto: omap-aes - Add CTR algorithm SupportMark A. Greer2013-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
