* crypto: compress - Add pcomp interfaceGeert Uytterhoeven2009-03-046-0/+257
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* hwrng: timeriomem - New driverAlexander Clouter2009-02-224-0/+187
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some hardware platforms, the TS-7800[1] is one for example, can supply the kernel with an entropy source, albeit a slow one for TS-7800 users, by just reading a particular IO address. This source must not be read above a certain rate otherwise the quality suffers. The driver is then hooked into by calling platform_device_(register|add|del) passing a structure similar to: ------ static struct timeriomem_rng_data ts78xx_ts_rng_data = { .address = (u32 *__iomem) TS_RNG, .period = 1000000, /* one second */ }; static struct platform_device ts78xx_ts_rng_device = { .name = "timeriomem_rng", .id = -1, .dev = { .platform_data = &ts78xx_ts_rng_data, }, .num_resources = 0, }; ------ [1] http://www.embeddedarm.com/products/board-detail.php?product=TS-7800 Signed-off-by: Alexander Clouter <alex@digriz.org.uk> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

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.

* crypto: testmgr - Test skciphers with no IVsHerbert Xu2009-02-181-4/+16
| | | | | | | | | | | | | | | | | As it is an skcipher with no IV escapes testing altogether because we only test givcipher objects. This patch fixes the bypass logic to test these algorithms. Conversely, we're currently testing nivaead algorithms with IVs, which would have deadlocked had it not been for the fact that no nivaead algorithms have any test vectors. This patch also fixes that case. Both fixes are ugly as hell, but this ugliness should hopefully disappear once we move them into the per-type code (i.e., the AEAD test would live in aead.c and the skcipher stuff in ablkcipher.c).

* crypto: aead - Avoid infinite loop when nivaead fails selftestHerbert Xu2009-02-181-0/+16
| | | | | | | | | | | | | | | | | | | When an aead constructed through crypto_nivaead_default fails its selftest, we'll loop forever trying to construct new aead objects but failing because it already exists. The crux of the issue is that once an aead fails the selftest, we'll ignore it on the next run through crypto_aead_lookup and attempt to construct a new aead. We should instead return an error to the caller if we find an an that has failed the test. This bug hasn't manifested itself yet because we don't have any test vectors for the existing nivaead algorithms. They're tested through the underlying algorithms only.

The crux of the issue is that once a givcipher fails the selftest, we'll ignore it on the next run through crypto_skcipher_lookup and attempt to construct a new givcipher.

* crypto: api - Fix crypto_alloc_tfm/create_create_tfm return conventionHerbert Xu2009-02-184-26/+16
| | | | | | | | | | | | | | | | | | | | | | | | This is based on a report and patch by Geert Uytterhoeven. The functions crypto_alloc_tfm and create_create_tfm return a pointer that needs to be adjusted by the caller when successful and otherwise an error value. This means that the caller has to check for the error and only perform the adjustment if the pointer returned is valid. Since all callers want to make the adjustment and we know how to adjust it ourselves, it's much easier to just return adjusted pointer directly. The only caveat is that we have to return a void * instead of struct crypto_tfm *. However, this isn't that bad because both of these functions are for internal use only (by types code like shash.c, not even algorithms code). This patch also moves crypto_alloc_tfm into crypto/internal.h (crypto_create_tfm is already there) to reflect this. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: api - crypto_alg_mod_lookup either tested or untestedHerbert Xu2009-02-181-1/+1
| | | | | | | | | | | As it stands crypto_alg_mod_lookup will search either tested or untested algorithms, but never both at the same time. However, we need exactly that when constructing givcipher and aead so this patch adds support for that by setting the tested bit in type but clearing it in mask. This combination is currently unused.

* crypto: ansi_cprng - Panic on CPRNG test failure when in FIPS mode Neil Horman2009-02-181-0/+6
| | | | | | | | | | | | | FIPS 140-2 specifies that all access to various cryptographic modules be prevented in the event that any of the provided self tests fail on the various implemented algorithms. We already panic when any of the test in testmgr.c fail when we are operating in fips mode. The continuous test in the cprng here was missed when that was implmented. This code simply checks for the fips_enabled flag if the test fails, and warns us via syslog or panics the box accordingly.

* crypto: ansi_cprng - Force reset on allocationNeil Horman2009-02-181-1/+10
| | | | | | | | | | | | | | Pseudo RNGs provide predictable outputs based on input parateters {key, V, DT}, the idea behind them is that only the user should know what the inputs are. While its nice to have default known values for testing purposes, it seems dangerous to allow the use of those default values without some sort of safety measure in place, lest an attacker easily guess the output of the cprng. This patch forces the NEED_RESET flag on when allocating a cprng context, so that any user is forced to reseed it before use. The defaults can still be used for testing, but this will prevent their inadvertent use, and be more secure.

* crypto: aes-ni - Add support to Intel AES-NI instructions for x86_64 platformHuang Ying2009-02-185-0/+1386
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | It turns out that LRW has never worked properly on big endian. This was never discussed because nobody actually used it that way. In fact, it was only discovered when Geert Uytterhoeven loaded it through tcrypt which failed the test on it. The fix is straightforward, on big endian the to find the nth bit we should be grouping them by words instead of bytes. So setbit128_bbe should xor with 128 - BITS_PER_LONG instead of 128 - BITS_PER_BYTE == 0x78.

For a single digital output (e.g. in patch_conexant.c), this call isn't needed. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change HP dv7 quirk: although reported to work with hp-m4 model (https://bugzilla.novell.com/show_bug.cgi?id=445321), the original report doesn't contain info about testing of internal microphone. Recently I received a report about internal mic not working (https://qa.mandriva.com/show_bug.cgi?id=44855#c193), this must be related with the forced line in on pin 0x0e done with hp-m4 model. Thus change the current quirk from STAC_HP_M4 to STAC_HP_DV5, later reported to be fixed on a provided kernel with this change (https://qa.mandriva.com/show_bug.cgi?id=44855#c196).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We found that enabling/disabling HDMI audio pin out at stream start/stop time will kill the leading 500ms or so sound samples. Avoid this by enabling pin out once and for ever at module loading time. The leading ~500ms audio samples will still be lost when switching from X-channel playback to Y-channel playback where X != Y. However there's no much we can do about it: the audio infoframe has to change and it looks like either G45 or YAMAHA requires some time to switch the configuration.

| | * | ALSA: hda - allow multi-channel HDMI audio playback when ELD is not presentWu Fengguang2009-02-111-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The YAMAHA AV-X1800 requires audio infoframe to include speaker-channel mapping to play >2 channel HDMI audio. In theory that mapping should be derived from its speaker configurations contained in its ELD. However we currently cannot get ELD in console before the KMS functionalities are ready. This is a more or less general issue at least in the near future. As a workaround, we propose to allow playback of mult-channel audio when ELD is not available.

It should still work with any version of the library from the 2003 onwards which provide their own headers for the latest interface.
