Subject: [PATCH 5.8 173/186] mm: track page table modifications in __apply_to_page_range()
Date: Tue,  8 Sep 2020 17:25:15 +0200	[thread overview]
Message-ID: <20200908152250.046403540@linuxfoundation.org> (raw)
In-Reply-To: <20200908152241.646390211@linuxfoundation.org>

From: Joerg Roedel <jroedel@suse.de>

commit e80d3909be42f7e38cc350c1ba109cf0aa51956a upstream.

__apply_to_page_range() is also used to change and/or allocate
page-table pages in the vmalloc area of the address space.  Make sure
these changes get synchronized to other page-tables in the system by
calling arch_sync_kernel_mappings() when necessary.

The impact appears limited to x86-32, where apply_to_page_range may miss
updating the PMD.  That leads to explosions in drivers like

  BUG: unable to handle page fault for address: fe036000
  #PF: supervisor write access in kernel mode
  #PF: error_code(0x0002) - not-present page
  *pde = 00000000

  CR2: 00000000fe036000

It looks like kasan, xen and i915 are vulnerable.

Actual impact is "on thinkpad X60 in 5.9-rc1, screen starts blinking
after 30-or-so minutes, and machine is unusable"
