Subject: [PATCHv2 0/4] WX checking for arm64
Date: Wed, 12 Oct 2016 15:31:58 -0700 [thread overview]
Message-ID: <1476311522-15381-1-git-send-email-labbott@redhat.com> (raw)
Hi,
This is v2 of the implementation to check for writable and executable pages on
arm64.
Major changes since v1:
- I realized my concerns about initialization and registration were unfounded
so registration to register page tables with debugfs is simplified.
- New patch to remove max_addr since it was pointed out it was unused.
- Rebased to include changes for the EFI page tables as well.
- Checking is now only done on the init_mm page tables. It was mentioned that
we should check the hyp page tables as well but that can be follow on work.
- Checking for UXN per suggestion from Mark Rutland.
