crypto: bcm - convert to use crypto_authenc_extractkeys()

2019-01-10T13:37:31Z

Convert the bcm crypto driver to use crypto_authenc_extractkeys() so that it picks up the fix for broken validation of rtattr::rta_len. This also fixes the DES weak key check to actually be done on the right key. (It was checking the authentication key, not the encryption key...)

treewide: surround Kconfig file paths with double quotes

2018-12-21T15:25:54Z

The Kconfig lexer supports special characters such as '.' and '/' in the parameter context. In my understanding, the reason is just to support bare file paths in the source statement. I do not see a good reason to complicate Kconfig for the room of ambiguity. The majority of code already surrounds file paths with double quotes, and it makes sense since file paths are constant string literals. Make it treewide consistent now.

s390/zcrypt: multiple zcrypt device nodes support

2018-10-08T07:09:58Z

This patch is an extension to the zcrypt device driver to provide, support and maintain multiple zcrypt device nodes. The individual zcrypt device nodes can be restricted in terms of crypto cards, domains and available ioctls. Such a device node can be used as a base for container solutions like docker to control and restrict the access to crypto resources. The handling is done with a new sysfs subdir /sys/class/zcrypt. Echoing a name (or an empty sting) into the attribute "create" creates a new zcrypt device node. In /sys/class/zcrypt a new link will appear which points to the sysfs device tree of this new device. The attribute files "ioctlmask", "apmask" and "aqmask" in this directory are used to customize this new zcrypt device node instance. Finally the zcrypt device node can be destroyed by echoing the name into /sys/class/zcrypt/destroy. The internal structs holding the device info are reference counted - so a destroy will not hard remove a device but only marks it as removable when the reference counter drops to zero. The mask values are bitmaps in big endian order starting with bit 0. So adapter number 0 is the leftmost bit, mask is 0x8000... The sysfs attributes accept 2 different formats: * Absolute hex string starting with 0x like "0x12345678" does set the mask starting from left to right. If the given string is shorter than the mask it is padded with 0s on the right. If the string is longer than the mask an error comes back (EINVAL). * Relative format - a concatenation (done with ',') of the terms +[-] or -[-]. may be any valid number (hex, decimal or octal) in the range 0...255. Here are some examples: "+0-15,+32,-128,-0xFF" "-0-255,+1-16,+0x128" "+1,+2,+3,+4,-5,-7-10" A simple usage examples: # create new zcrypt device 'my_zcrypt': echo "my_zcrypt" >/sys/class/zcrypt/create # go into the device dir of this new device echo "my_zcrypt" >create cd my_zcrypt/ ls -l total 0 -rw-r--r-- 1 root root 4096 Jul 20 15:23 apmask -rw-r--r-- 1 root root 4096 Jul 20 15:23 aqmask -r--r--r-- 1 root root 4096 Jul 20 15:23 dev -rw-r--r-- 1 root root 4096 Jul 20 15:23 ioctlmask lrwxrwxrwx 1 root root 0 Jul 20 15:23 subsystem -> ../../../../class/zcrypt ... # customize this zcrypt node clone # enable only adapter 0 and 2 echo "0xa0" >apmask # enable only domain 6 echo "+6" >aqmask # enable all 256 ioctls echo "+0-255" >ioctls # now the /dev/my_zcrypt may be used # finally destroy it echo "my_zcrypt" >/sys/class/zcrypt/destroy Please note that a very similar 'filtering behavior' also applies to the parent z90crypt device. The two mask attributes apmask and aqmask in /sys/bus/ap act the very same for the z90crypt device node. However the implementation here is totally different as the ap bus acts on bind/unbind of queue devices and associated drivers but the effect is still the same. So there are two filters active for each additional zcrypt device node: The adapter/domain needs to be enabled on the ap bus level and it needs to be active on the zcrypt device node level.

crypto: hisilicon - SEC security accelerator driver

2018-08-03T10:06:02Z

This accelerator is found inside hisilicon hip06 and hip07 SoCs. Each instance provides a number of queues which feed a different number of backend acceleration units. The queues are operating in an out of order mode in the interests of throughput. The silicon does not do tracking of dependencies between multiple 'messages' or update of the IVs as appropriate for training. Hence where relevant we need to do this in software.
