Subject: [MODERATED] [PATCH 0/8] L1TFv8 2
Date: Wed, 13 Jun 2018 15:48:20 -0700 [thread overview]
Message-ID: <cover.1528929489.git.ak@linux.intel.com> (raw)
This is v8 of the native OS patchkit to mitigate the L1TF side channel.
It does not cover KVM.
This version addresses the latest review feedbacks. The mitigation
setup has been moved into check_bugs, and the memory size checking
patch is now integrated into the standard setup. The swap mitigation
has been split into two patches. Various other changes.
For more details see the individual changelogs.
Andi Kleen (6):
x86/speculation/l1tf: Increase 32bit PAE __PHYSICAL_PAGE_MASK
x86/speculation/l1tf: Protect PROT_NONE PTEs against speculation
x86/speculation/l1tf: Make sure the first page is always reserved
x86/speculation/l1tf: Add sysfs reporting for l1tf
x86/speculation/l1tf: Disallow non privileged high MMIO PROT_NONE
mappings
x86/speculation/l1tf: Limit swap file size to MAX_PA/2
Linus Torvalds (2):
x86/speculation/l1tf: Change order of offset/type in swap entry
