* crypto: compress - Add pcomp interfaceGeert Uytterhoeven2009-03-041-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current "comp" crypto interface supports one-shot (de)compression only, i.e. the whole data buffer to be (de)compressed must be passed at once, and the whole (de)compressed data buffer will be received at once. In several use-cases (e.g. compressed file systems that store files in big compressed blocks), this workflow is not suitable. Furthermore, the "comp" type doesn't provide for the configuration of (de)compression parameters, and always allocates workspace memory for both compression and decompression, which may waste memory. To solve this, add a "pcomp" partial (de)compression interface that provides the following operations: - crypto_compress_{init,update,final}() for compression, - crypto_decompress_{init,update,final}() for decompression, - crypto_{,de}compress_setup(), to configure (de)compression parameters (incl. allocating workspace memory). The (de)compression methods take a struct comp_request, which was mimicked after the z_stream object in zlib, and contains buffer pointer and length pairs for input and output. The setup methods take an opaque parameter pointer and length pair. Parameters are supposed to be encoded using netlink attributes, whose meanings depend on the actual (name of the) (de)compression algorithm.

* crypto: cryptd - Per-CPU thread implementation based on kcrypto_wqHuang Ying2009-02-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Original cryptd thread implementation has scalability issue, this patch solve the issue with a per-CPU thread implementation. struct cryptd_queue is defined to be a per-CPU queue, which holds one struct cryptd_cpu_queue for each CPU. In struct cryptd_cpu_queue, a struct crypto_queue holds all requests for the CPU, a struct work_struct is used to run all requests for the CPU. Testing based on dm-crypt on an Intel Core 2 E6400 (two cores) machine shows 19.2% performance gain. The testing script is as follow: -------------------- script begin --------------------------- #!/bin/sh dmc_create() { # Create a crypt device using dmsetup dmsetup create $2 --table "0 `blockdev --getsize $1` crypt cbc(aes-asm)?cryptd?plain:plain babebabebabebabebabebabebabebabe 0 $1 0" } dmsetup remove crypt0 dmsetup remove crypt1 dd if=/dev/zero of=/dev/ram0 bs=1M count=4 >& /dev/null dd if=/dev/zero of=/dev/ram1 bs=1M count=4 >& /dev/null dmc_create /dev/ram0 crypt0 dmc_create /dev/ram1 crypt1 cat >tr.sh <<EOF #!/bin/sh for n in \$(seq 10); do dd if=/dev/dm-0 of=/dev/null >& /dev/null & dd if=/dev/dm-1 of=/dev/null >& /dev/null & done wait EOF for n in $(seq 10); do /usr/bin/time sh tr.sh done rm tr.sh -------------------- script end --------------------------- The separator of dm-crypt parameter is changed from "-" to "?", because "-" is used in some cipher driver name too, and cryptds need to specify cipher driver name instead of cipher name. The test result on an Intel Core2 E6400 (two cores) is as follow: without patch: -----------------wo begin -------------------------- 0.04user 0.38system 0:00.39elapsed 107%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6566minor)pagefaults 0swaps 0.07user 0.35system 0:00.35elapsed 121%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6567minor)pagefaults 0swaps 0.06user 0.34system 0:00.30elapsed 135%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6562minor)pagefaults 0swaps 0.05user 0.37system 0:00.36elapsed 119%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6607minor)pagefaults 0swaps 0.06user 0.36system 0:00.35elapsed 120%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6562minor)pagefaults 0swaps 0.05user 0.37system 0:00.31elapsed 136%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6594minor)pagefaults 0swaps 0.04user 0.34system 0:00.30elapsed 126%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6597minor)pagefaults 0swaps 0.06user 0.32system 0:00.31elapsed 125%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6571minor)pagefaults 0swaps 0.06user 0.34system 0:00.31elapsed 134%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6581minor)pagefaults 0swaps 0.05user 0.38system 0:00.31elapsed 138%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6600minor)pagefaults 0swaps -----------------wo end -------------------------- with patch: ------------------w begin -------------------------- 0.02user 0.31system 0:00.24elapsed 141%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6554minor)pagefaults 0swaps 0.05user 0.34system 0:00.31elapsed 127%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6606minor)pagefaults 0swaps 0.07user 0.33system 0:00.26elapsed 155%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6559minor)pagefaults 0swaps 0.07user 0.32system 0:00.26elapsed 151%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6562minor)pagefaults 0swaps 0.05user 0.34system 0:00.26elapsed 150%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6603minor)pagefaults 0swaps 0.03user 0.36system 0:00.31elapsed 124%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6562minor)pagefaults 0swaps 0.04user 0.35system 0:00.26elapsed 147%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6586minor)pagefaults 0swaps 0.03user 0.37system 0:00.27elapsed 146%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6562minor)pagefaults 0swaps 0.04user 0.36system 0:00.26elapsed 154%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6594minor)pagefaults 0swaps 0.04user 0.35system 0:00.26elapsed 154%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+6557minor)pagefaults 0swaps ------------------w end -------------------------- The middle value of elapsed time is: wo cryptwq: 0.31 w cryptwq: 0.26 The performance gain is about (0.31-0.26)/0.26 = 0.192.

* crypto: aes-ni - Add support to Intel AES-NI instructions for x86_64 platformHuang Ying2009-02-181-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | Intel AES-NI is a new set of Single Instruction Multiple Data (SIMD) instructions that are going to be introduced in the next generation of Intel processor, as of 2009. These instructions enable fast and secure data encryption and decryption, using the Advanced Encryption Standard (AES), defined by FIPS Publication number 197. The architecture introduces six instructions that offer full hardware support for AES. Four of them support high performance data encryption and decryption, and the other two instructions support the AES key expansion procedure. The white paper can be downloaded from: http://softwarecommunity.intel.com/isn/downloads/intelavx/AES-Instructions-Set_WP.pdf AES may be used in soft_irq context, but MMX/SSE context can not be touched safely in soft_irq context. So in_interrupt() is checked, if in IRQ or soft_irq context, the general x86_64 implementation are used instead.

* libcrc32c: Move implementation to crypto crc32cHerbert Xu2008-12-251-3/+1
| | | | | | | | | | | | | | This patch swaps the role of libcrc32c and crc32c. Previously the implementation was in libcrc32c and crc32c was a wrapper. Now the code is in crc32c and libcrc32c just calls the crypto layer. The reason for the change is to tap into the algorithm selection capability of the crypto API so that optimised implementations such as the one utilising Intel's CRC32C instruction can be used where available.

* crypto: api - Disallow cryptomgr as a module if algorithms are built-inHerbert Xu2008-12-101-4/+32
| | | | | | | | | | | | | If we have at least one algorithm built-in then it no longer makes sense to have the testing framework, and hence cryptomgr to be a module. It should be either on or off, i.e., built-in or disabled. This just happens to stop a potential runaway modprobe loop that seems to trigger on at least one distro. With fixes from Evgeniy Polyakov.

| | | | | | | | | | | | | | | Add the ability to turn FIPS-compliant mode on or off at boot In order to be FIPS compliant, several check may need to be preformed that may be construed as unusefull in a non-compliant mode.

It also exports that mode information to user space via a sysctl (/proc/sys/crypto/fips_enabled). Tested successfully by me.
