crypto: ux500/crypt: Mark expected switch fall-throughs

2019-08-10T00:49:04Z

Mark switch cases where we are expecting to fall through.

crypto: ux500 - use ccflags-y instead of CFLAGS_.o

Instead of adding CFLAGS_.o to every file, let's use ccflags-y, which is effective for all C files in the directory. No behavior change. Signed-off-by: Masahiro Yamada Signed-off-by: Herbert Xu

crypto: ux500 - Forbid 2-key 3DES in FIPS mode

2019-04-18T14:15:01Z

This patch forbids the use of 2-key 3DES (K1 == K3) in FIPS mode. It also removes the registration of the non-standard des/des3 ablkcipher algorithms. Signed-off-by: Herbert Xu

crypto: clarify name of WEAK_KEY request flag

2019-01-25T10:41:52Z

CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it sounds like it is requesting a weak key. Actually, it is requesting that weak keys be forbidden (for algorithms that have the notion of "weak keys"; currently only DES and XTS do). Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which it can be easily confused. (This in fact happened in the UX500 driver, though just in some debugging messages.) Therefore, make the intent clear by renaming it to CRYPTO_TFM_REQ_FORBID_WEAK_KEYS. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

Merge tag 'char-misc-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver updates from Greg KH: "Here is the bit set of char/misc drivers for 4.19-rc1 There is a lot here, much more than normal, seems like everyone is writing new driver subsystems these days... Anyway, major things here are: - new FSI driver subsystem, yet-another-powerpc low-level hardware bus - gnss, finally an in-kernel GPS subsystem to try to tame all of the crazy out-of-tree drivers that have been floating around for years, combined with some really hacky userspace implementations. This is only for GNSS receivers, but you have to start somewhere, and this is great to see. Other than that, there are new slimbus drivers, new coresight drivers, new fpga drivers, and loads of DT bindings for all of these and existing drivers.
