* fs: ubifs: Add authentication supportSascha Hauer2019-04-241-0/+5
| | | | | | | | | | | | This adds UBIFS authentication support. For now, we do not do any authentication even on authenticated UBIFS images. Since this behaviour is not what the user normally expects when mounting authenticated images we only do this when the user explicitly allows it in "global.ubifs.allow_authenticated_unauthenticated". If the flag is false then we refuse mounting such an image and return -EPERM instead. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* crypto: digest: Change the signature of digest_file_window()Andrey Smirnov2019-01-161-1/+1
| | | | | | | | | On 32-bit systems "ulong" will limit digest_file_window()'s maximum size to 4 GiB. Convert "start" and "size" to "loff_t" in order to be able to handle maximum file size supported by the rest of the system.

* digest.h: Sync hash_algo values with kernelSascha Hauer2018-10-081-1/+7
| | | | | | | | enum hash_algo is exported from the Kernel, so sync it with the numbers that are exported. Since we have barebox specific extensions to the hash_algo list add a big comment and put the extenstions at the end. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* crypto: add CRC32 digestYegor Yefremov2016-05-251-0/+1

* crypto: add digest_alloc_by_algo()Sascha Hauer2016-01-261-0/+23
| | | | | | | | | | | In barebox the function digest_alloc() allocates a digest based on a string. When a subsystem already uses an integer value to identify a digest it makes no sense to create a string and pass it to digest_alloc(), where it is parsed again. This patch adds the possibility to get a digest by an enum.

* crypto: prepare to allow multiple digest driverJean-Christophe PLAGNIOL-VILLARD2015-03-271-3/+9
| | | | | | | | | | This will allow to have hw driver or asm optimised driver. Use a priority level to determine which one to use at runtime. The generic one will be 0. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* digest: add digest callbackJean-Christophe PLAGNIOL-VILLARD2015-03-191-0/+8
| | | | | | | | | | | Combination of @init and @update and @final. This function effectively behaves as the entire chain of operations, @init, @update and @final issued in sequence. This is added for hardware which cannot do even the @finup, but can only do the whole transformation in one run.
