[PATCH 0/2] xen: fix illegal rtc device usage of pv guests

by Juergen Gross

A recent change in mc146818_get_time() resulted in WARN splats when booting a Xen PV guest. The main reason is that there is a code path resulting in accessing a RTC device which is not present, which has been made obvious by a call of WARN() in this case. This small series is fixing this issue by: - avoiding the RTC device access from drivers/base/power/trace.c in cast there is no legacy RTC device available - resetting the availability flag of a legacy RTC device for Xen PV guests Juergen Gross (2): PM: base: power: don't try to use non-existing RTC for storing data xen: reset legacy rtc flag for PV domU arch/x86/xen/enlighten_pv.c | 7 +++++++ drivers/base/power/trace.c | 10 ++++++++++ 2 files changed, 17 insertions(+) -- 2.26.2

FAILED: patch "[PATCH] xhci: fix unsafe memory usage in xhci tracing" failed to apply to 4.9-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.9-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From cbf286e8ef8337308c259ff5b9ce2e74d403be5a Mon Sep 17 00:00:00 2001 From: Mathias Nyman <mathias.nyman(a)linux.intel.com> Date: Fri, 20 Aug 2021 15:34:58 +0300 Subject: [PATCH] xhci: fix unsafe memory usage in xhci tracing Removes static char buffer usage in the following decode functions: xhci_decode_trb() xhci_decode_ptortsc() Caller must provide a buffer to use. In tracing use __get_str() as recommended to pass buffer. Minor chanes are needed in xhci debugfs code as these functions are also used there.
