* crypto: omap-aes - Fix CTR mode counter lengthJoel Fernandes2013-10-30
| | | | | | | | | NIST vectors for CTR mode in testmgr.h assume the entire IV as the counter. To get correct results that match the output of these vectors, we need to set the counter length correctly.

* padata: make the sequence counter an atomic_tMathias Krause2013-10-30
| | | | | | | | | | | | | | | | | | | | Using a spinlock to atomically increase a counter sounds wrong -- we've atomic_t for this! Also move 'seq_nr' to a different cache line than 'lock' to reduce cache line trashing. This has the nice side effect of decreasing the size of struct parallel_data from 192 to 128 bytes for a x86-64 build, e.g. occupying only two instead of three cache lines. Those changes results in a 5% performance increase on an IPsec test run using pcrypt. Btw. the seq_lock spinlock was never explicitly initialized -- one more reason to get rid of it.

| | | | | | | | | | | | | | | | | | | | | | 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. (Earlier the initialization of Job ring was done by the controller driver) 2.

* crypto: skcipher - Use eseqiv even on UP machinesHerbert Xu2013-10-29
| | | | | | | | | | | | | | | | | Previously we would use eseqiv on all async ciphers in all cases, and sync ciphers if we have more than one CPU. This meant that chainiv is only used in the case of sync ciphers on a UP machine. As chainiv may aid attackers by making the IV predictable, even though this risk itself is small, the above usage pattern causes it to further leak information about the host. This patch addresses these issues by using eseqiv even if we're on a UP machine.

* crypto: crypto_memneq - add equality testing of memory regions w/o timing leaksJames Yonan2013-10-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When comparing MAC hashes, AEAD authentication tags, or other hash values in the context of authentication or integrity checking, it is important not to leak timing information to a potential attacker, i.e. when communication happens over a network. Bytewise memory comparisons (such as memcmp) are usually optimized so that they return a nonzero value as soon as a mismatch is found. E.g, on x86_64/i5 for 512 bytes this can be ~50 cyc for a full mismatch and up to ~850 cyc for a full match (cold). This early-return behavior can leak timing information as a side channel, allowing an attacker to iteratively guess the correct result. This patch adds a new method crypto_memneq ("memory not equal to each other") to the crypto API that compares memory areas of the same length in roughly "constant time" (cache misses could change the timing, but since they don't reveal information about the content of the strings being compared, they are effectively benign). Iow, best and worst case behaviour take the same amount of time to complete (in contrast to memcmp). Note that crypto_memneq (unlike memcmp) can only be used to test for equality or inequality, NOT for lexicographical order. This, however, is not an issue for its use-cases within the crypto API. We tried to locate all of the places in the crypto API where memcmp was being used for authentication or integrity checking, and convert them over to crypto_memneq. crypto_memneq is declared noinline, placed in its own source file, and compiled with optimizations that might increase code size disabled ("Os") because a smart compiler (or LTO) might notice that the return value is always compared against zero/nonzero, and might then reintroduce the same early-return optimization that we are trying to avoid. Using #pragma or __attribute__ optimization annotations of the code for disabling optimization was avoided as it seems to be considered broken or unmaintained for long time in GCC [1]. Therefore, we work around that by specifying the compile flag for memneq.o directly in the Makefile. We found that this seems to be most appropriate. As we use ("Os"), this patch also provides a loop-free "fast-path" for frequently used 16 byte digests. Similarly to kernel library string functions, leave an option for future even further optimized architecture specific assembler implementations. This was a joint work of James Yonan and Daniel Borkmann. Also thanks for feedback from Florian Weimer on this and earlier proposals [2].

* crypto: caam - fix RNG4 instantiationAlex Porosanu2013-09-13
| | | | | | | | | | | | | | | | | | | | | 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.

* crypto: tegra - use kernel entropy instead of ad-hocLinus Walleij2013-09-13
| | | | | | | | | | | | | | | | | | | The way I read the Tegra AES RNG is that it has a homebrew algorithm for initializing the 128bit RNG using timespec and the unique chip ID. This looks like reinventing the (square) wheel, instead just grab 128bits from the kernel entropy pool where the time and (after another patch) chip unique ID is already mixed in. Incidentally this also gets rid of a rather ugly cross-dependence on the machine using an extern declaration.
