Subject: [PATCH 0/3] PTI x86-32 Updates and Fixes
Date: Wed, 25 Jul 2018 17:48:00 +0200 [thread overview]
Message-ID: <1532533683-5988-1-git-send-email-joro@8bytes.org> (raw)
Hi,
here are three patches on-top of tip/x86/pti to update the
vmallo_fault() fix and also with another important fix.
The first two patches remove the WARN_ON_ONCE(in_nmi) from
the vmalloc_fault() function and revert the previous fix, as
discussed at the last patch-set.
The third patch is an important fix for a silent memory
corruption issue found by the trinity fuzzer, which did take
a while to track down. But I found it and with the fix the
fuzzer already runs for couple of hours now and the VM is
still alive.
Regards,
Joerg
