2009-07-16crypto: padlock - Fix hashing of partial blocksHerbert Xu1-0/+2
When we encounter partial blocks in finup, we'll invoke the xsha instruction with a bogus count that is not a multiple of the block size. This patch fixes it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2009-07-15crypto: padlock - Fix compile error on i386Herbert Xu1-2/+4
The previous change to allow hashing from states other than the initial broke compilation on i386 because the inline assembly tried to squeeze a u64 into a 32-bit register. As we've already checked for 32-bit overflows we can simply truncate it to u32, or unsigned long so that we don't truncate at all on x86-64. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2009-07-15crypto: crypto4xx - Disable SHA implementationHerbert Xu1-19/+0
The crypto4xx SHA implementation keeps the hash state in the tfm data structure. This breaks a fundamental requirement of ahash implementations that they must be reentrant. This patch disables the broken implementation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2009-07-14crypto: crypto4xx - Switch to new style ahashHerbert Xu2-39/+71
This patch changes crypto4xx to use the new style ahash type. In particular, we now use ahash_alg to define ahash algorithms instead of crypto_alg. This is achieved by introducing a union that encapsulates the new type and the existing crypto_alg structure. They're told apart through a u32 field containing the type value.

2009-07-14crypto: crypto4xx - Use crypto_ahash_set_reqsizeHerbert Xu2-2/+4
This patch makes crypto4xx use crypto_ahash_set_reqsize to avoid accessing crypto_ahash directly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2009-07-14crypto: padlock - Switch sha to shashHerbert Xu2-179/+156
This patch converts the padlock-sha implementation to shash. In doing so the existing mechanism of storing the data until final is no longer viable as we do not have a way of allocating data in crypto_shash_init and then reliably freeing it. This is just as well because a better way of handling the problem is to hash everything but the last chunk using normal sha code and then provide the intermediate result to the padlock device. This is good enough because the primary application of padlock-sha is IPsec and there the data is laid out in the form of an hmac header followed by the rest of the packet. In essence we can provide all the data to the padlock as the hmac header only needs to be hashed once. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2009-06-18random: Add optional continuous repetition test to entropy store based rngsNeil Horman1-0/+14
FIPS-140 requires that all random number generators implement continuous self tests in which each extracted block of data is compared against the last block for repetition. The ansi_cprng implements such a test, but it would be nice if the hw rng's did the same thing. Obviously its not something thats always needed, but it seems like it would be a nice feature to have on occasion. I've written the below patch which allows individual entropy stores to be flagged as desiring a continuous test to be run on them as is extracted. By default this option is off, but is enabled in the event that fips mode is selected during bootup.

The PCAP Asic as present on EZX phones is a multi function device with voltage regulators, ADC, touch screen controller, RTC, USB transceiver, leds controller, and audio codec. It has two SPI ports, typically one is connected to the application processor and another to the baseband, this driver provides read/write functions to its registers, irq demultiplexer and ADC queueing/abstraction. This chip is used on a lot of Motorola phones, it was manufactured by TI as a custom product with the name PTWL93017, later this design evolved into the ATLAS PMIC from Freescale (MC13783).

Migrating piecemeal is too painful; this giant patch fixes all compilation warnings and errors that come as a result of switching to use int-ll64.h. Note that userspace will still see __u64 defined as unsigned long. This is important as it affects C++ name mangling.

2009-06-16tcx: use standard fields for framebuffer physical address and lengthKrzysztof Helt1-14/+13
Use standard fields fbinfo.fix.smem_start and fbinfo.fix.smem_len for physical address and length of framebuffer. This also fixes output of the 'fbset -i' command - address and length of the framebuffer are displayed correctly. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Acked-by: David S.

2009-06-16fbdev: add support for handoff from firmware to hw framebuffersDave Airlie4-2/+57
With KMS we have ran into an issue where we really want the KMS fb driver to be the one running the console, so panics etc can be shown by switching out of X etc. However with vesafb/efifb built-in, we end up with those on fb0 and the KMS fb driver on fb1, driving the same piece of hw, so this adds an fb info flag to denote a firmware fbdev, and adds a new aperture base/size range which can be compared when the hw drivers are installed to see if there is a conflict with a firmware driver, and if there is the firmware driver is unregistered and the hw driver takes over. It uses new aperture_base/size members instead of comparing on the fix smem_start/length, as smem_start/length might for example only cover the first 1MB of the PCI aperture, and we could allocate the kms fb from 8MB into the aperture, thus they would never overlap.

2009-06-16intelfb: fix a bug when changing video timingPaul Menzel1-0/+5
When changing video timing dynamically via fbset the screen sporadically is rendered black. With the attached fix which disables VCO prior to timing register change the problem disappears. I had a look at the Xserver register setup code. Here the VCO is disabled in the same way [1]. This patch is taken from vga-sync-field version 0.0.11 [2][3].
