** Changed in: linux (Ubuntu Xenial)
Status: Confirmed => In Progress
** Changed in: linux (Ubuntu Xenial)
Assignee: (unassigned) => dann frazier (dannf)
** Description changed:
[Impact]
The sha{1,2}_ce modules no longer load on arm64, preventing the use of the
hardware accelerated ARMv8 crypto extensions for SHA1, SHA-224/SHA-256.
[Test Case]
sudo modprobe sha1_ce
Currently fails:
[ 33.838295] module sha1_ce: unsupported RELA relocation: 275
[Fix]
+ For now I suggest reverting the commit that introduced the regression:
+ 2675530a1d16 crypto: arm64/sha - avoid non-standard inline asm tricks
[Where problems could occur]
- TBD
+ The purpose of this commit appears to be better compatibility with Clang, so
regressions are likely to be with any developers using Clang with our kernel
source.
