From: Dan Williams Date: Tue, 30 Jan 2018 01:03:21 +0000 (-0800) Subject: x86/spectre: Report get_user mitigation for spectre_v1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0a1595d2924df1f2380bb230bee05b0432624688;p=pandora-kernel.git x86/spectre: Report get_user mitigation for spectre_v1 commit edfbae53dab8348fca778531be9f4855d2ca0360 upstream. Reflect the presence of get_user(), __get_user(), and 'syscall' protections in sysfs. The expectation is that new and better tooling will allow the kernel to grow more usages of array_index_nospec(), for now, only claim mitigation for __user pointer de-references.
