* drm/doc: Make igts for cross-driver stuff strongly suggestedDaniel Vetter2019-02-071-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Compared to the RFC[1] no changes to the patch itself, but igt moved forward a lot: - gitlab CI builds with: reduced configs/libraries, arm cross build and a sysroot build (should address all the build/cross platform concerns raised in the RFC discussions). - tests reorganized into subdirectories so that the i915-gem tests don't clog the main/shared tests directory anymore - quite a few more non-intel people contributing/reviewing/committing igt tests patches. I think this addresses all the concerns raised in the RFC discussions, and assuming there's enough Acks and no new issues that pop up, we can go ahead with this. v2: - Use "should" (in the usual RFC sense) to make it clear that in the end this is all up to reviewer's discretion, as usual (Jani). - Also in the title s/mandatory/strongly suggested/ (me) - Make it clear we're not going to block features if a testcase is not feasible, given hw and state of igt, both having some good gaps in what can be tested (Harry, Eric, Sean, ...). 1: https://patchwork.kernel.org/patch/10648851/ Cc: Petri Latvala <petri.latvala@intel.com> Cc: Arkadiusz Hiler <arkadiusz.hiler@intel.com> Cc: Liviu Dudau <liviu.dudau@arm.com> Cc: Sean Paul <sean@poorly.run> Cc: Eric Anholt <eric@anholt.net> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Daniel Stone <daniel@fooishbar.org> Cc: "Wentland, Harry" <Harry.Wentland@amd.com> Cc: Brian Starkey <Brian.Starkey@arm.com> Reviewed-by: Eric Anholt <eric@anholt.net> (v1) Acked-by: Petri Latvala <petri.latvala@intel.com> Acked-by: Arkadiusz Hiler <arkadiusz.hiler@intel.com> Acked-by: Sean Paul <sean@poorly.run> Acked-by: "Wentland, Harry" <Harry.Wentland@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Acked-by: Liviu Dudau <liviu.dudau@arm.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Acked-by: Brian Starkey <brian.starkey@arm.com> Acked-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Acked-by: Boris Brezillon <boris.brezillon@collabora.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Acked-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190128172258.9585-1-daniel.vetter@ffwll.ch

| | * | kbuild: generate asm-generic wrappers if mandatory headers are missingMasahiro Yamada2019-01-061-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some time ago, Sam pointed out a certain degree of overwrap between generic-y and mandatory-y. (https://lkml.org/lkml/2017/7/10/121) I tweaked the meaning of mandatory-y a little bit; now it defines the minimum set of ASM headers that all architectures must have. If arch does not have specific implementation of a mandatory header, Kbuild will let it fallback to the asm-generic one by automatically generating a wrapper. This will allow to drop lots of redundant generic-y defines. Previously, "mandatory" was used in the context of UAPI, but I guess this can be extended to kernel space ASM headers.

Adiantum is a tweakable, length-preserving encryption mode with security provably reducible to that of XChaCha12 and AES-256, subject to a security bound. It's also a true wide-block mode, unlike XTS. See the paper "Adiantum: length-preserving encryption for entry-level processors" (https://eprint.iacr.org/2018/720.pdf) for more details. Also see commit 059c2a4d8e16 ("crypto: adiantum - add Adiantum support"). On sufficiently long messages, Adiantum's bottlenecks are XChaCha12 and the NH hash function. These algorithms are fast even on processors without dedicated crypto instructions. Adiantum makes it feasible to enable storage encryption on low-end mobile devices that lack AES instructions; currently such devices are unencrypted. On ARM Cortex-A7, on 4096-byte messages Adiantum encryption is about 4 times faster than AES-256-XTS encryption; decryption is about 5 times faster. In fscrypt, Adiantum is suitable for encrypting both file contents and names. With filenames, it fixes a known weakness: when two filenames in a directory share a common prefix of >= 16 bytes, with CTS-CBC their encrypted filenames share a common prefix too, leaking information. Adiantum does not have this problem. Since Adiantum also accepts long tweaks (IVs), it's also safe to use the master key directly for Adiantum encryption rather than deriving per-file keys, provided that the per-file nonce is included in the IVs and the master key isn't used for any other encryption mode. This configuration saves memory and improves performance. A new fscrypt policy flag is added to allow users to opt-in to this configuration.
