* crypto: algif - avoid excessive use of socket buffer in skcipherOndrej Kozina2014-09-041-1/+1
| | | | | | | | | | | On archs with PAGE_SIZE >= 64 KiB the function skcipher_alloc_sgl() fails with -ENOMEM no matter what user space actually requested. This is caused by the fact sock_kmalloc call inside the function tried to allocate more memory than allowed by the default kernel socket buffer size (kernel param net.core.optmem_max).

* crypto: lz4,lz4hc - fix decompressionKOVACS Krisztian2014-08-292-2/+2
| | | | | | | | | | | | | | | | | | | The lz4 library has two functions for decompression, with slightly different signatures and behaviour. The lz4_decompress_crypto() function seemed to be using the one that assumes that the decompressed length is known in advance. This patch switches to the other decompression function and makes sure that the length of the decompressed output is properly returned to the caller. The same issue was present in the lz4hc algorithm. Coincidentally, this change also makes very basic lz4 and lz4hc compression tests in testmgr pass.

* crypto: drbg - fix maximum value checks on 32 bit systemsStephan Mueller2014-08-261-0/+13
| | | | | | | | | | | | | | | | | The maximum values for additional input string or generated blocks is larger than 1<<32. To ensure a sensible value on 32 bit systems, return SIZE_MAX on 32 bit systems. This value is lower than the maximum allowed values defined in SP800-90A. The standard allow lower maximum values, but not larger values. SIZE_MAX - 1 is used for drbg_max_addtl to allow drbg_healthcheck_sanity to check the enforcement of the variable without wrapping.

* crypto: drbg - replace int2byte with cpu_to_beStephan Mueller2014-08-251-16/+18
| | | | | | | | | | | | | | | | | | | | The DRBG requires the conversion of an integer into a string representation of that integer. The previous implementation converted the given integer byte-wise. However, the kernel offers the cpu_to_be function which already re-arranges the memory representation of an integer such that it applies when interpreting the same memory as character string. The change therefore uses an integer-cast / union of the target character array together with the cpu_to_be function to convert an integer into its string representation. Tests show that the Hash and CTR DRBG implementations (the HMAC DRBG does not require such conversion) is about 10% faster (or requires less computing power, respectively).

* crypto: caam - change starting entropy delay valueAlex Porosanu2014-08-252-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | The entropy delay (the length in system clocks of each entropy sample) for the RNG4 block of CAAM is dependent on the frequency of the SoC. By elaborate methods, it has been determined that a good starting value for all platforms integrating the CAAM IP is 3200. Using a higher value has additional benefit of speeding up the process of instantiating the RNG, since the entropy delay will be increased and instantiation of the RNG state handles will be reattempted by the driver. If the starting value is low, for certain platforms, this can lead to a quite lengthy process. This patch changes the starting value of the length of the entropy sample to 3200 system clocks. In addition to this change, the attempted entropy delay values are now printed on the console upon initialization of the RNG block. While here, a safeguard for yielding the processor was added for ensuring that in very adverse cases, the CPU isn't hogged by the instantiation loop.

* crypto: caam - disable RNG oscillator maximum frequency checkAlex Porosanu2014-08-252-2/+3
| | | | | | | | | | | | | | | | The rtfrqmax & rtfrqmin set the bounds of the expected frequency of the oscillator, when SEC runs at its maximum frequency. For certain platforms (f.i. T2080), the oscillator is very fast and thus if the SEC runs at a lower than normal frequency, the ring oscillator is incorrectly detected as being out of bounds. This patch effectively disables the maximum frequency check, by setting a high enough maximum allowable frequency for the oscillator. The reasoning behind this is that usually a broken oscillator will run too slow (i.e. not run at all) rather than run too fast.

| * ideapad-laptop: Constify DMI table and other r/o variablesMathias Krause2014-08-161-2/+2
| | | | | | | | | | | | | | | | | | | | Constify the rfkill_blacklist[] DMI table, the ideapad_rfk_data[] table and the ideapad_attribute_group attribute group. There's no need to have them writeable during runtime.

| * asus-nb-wmi.c: Rename x401u quirk to wapf4Hans de Goede2014-08-161-13/+13
| | | | | | | | | | | | | | | | | | The actual x401u does not use the so named x401u quirk but the x55u quirk. All that the x401u quirk does it setting wapf to 4, so rename it to wapf4 to stop the confusion.

| * compal-laptop: correct invalid hwmon nameRoald Frederickx2014-08-161-1/+1
| | | | | | | | | | | | | | | | | | Change the name of the hwmon interface from "compal-laptop" to "compal". A dash is an invalid character for a hwmon name and caused the call to hwmon_device_register_with_groups() to fail.

| * toshiba_acpi: Add Qosmio X75-A to the alt keymap dmi listAzael Avalos2014-08-161-0/+7
| | | | | | | | | | | | | | | | | | | | | | The Toshiba Qosmio X75-A series models also come with the new keymap layout. This patch adds this model to the alt_keymap_dmi list, along with an extra key found on these models.

| * toshiba_acpi: Add extra check to backlight codeAzael Avalos2014-08-161-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Toshiba models (most notably Qosmios) come with an incomplete backlight method where the AML code doesn't check for write or read commands and always returns HCI_SUCCESS and the actual brightness (and in some cases the max brightness), thus allowing the backlight interface to be registered without write support. This patch changes the set_lcd_brightness function, checking the returned values for values greater than zero to avoid registering a broken backlight interface.
