Subject: [PATCH] Revert "cpupower Makefile change to help run the tool without
|
||||
'make install'"
|
||||
|
||||
This reverts commit 5c1de006e8e66b0be05be422416629e344c71652.
|
||||
|
||||
While the original commit makes it easier to run cpupower from the local build
|
||||
directory, it also leaves the binary with a rather poor rpath of './' in it
|
||||
after it is installed on a system via 'make install'.
|
||||
|
||||
This is considered bad practice and can cause cpupower to fail in rpmbuild
|
||||
with the following error:
|
||||
|
||||
ERROR 0004: file '/usr/bin/cpupower' contains an insecure rpath './' in [./]
|
||||
error: Bad exit status from /var/tmp/rpm-tmp.A6u26r (%install)
|
||||
Bad exit status from /var/tmp/rpm-tmp.A6u26r (%install)
|
||||
|
||||
Developers should be able to use LD_LIBRARY_PATH to achieve the same effect
|
||||
and not introduce rpath into the binary.

|
||||
Subject: [PATCH] xen-pciback: limit guest control of command register
|
||||
|
||||
Otherwise the guest can abuse that control to cause e.g. PCIe
|
||||
Unsupported Request responses (by disabling memory and/or I/O decoding
|
||||
and subsequently causing [CPU side] accesses to the respective address
|
||||
ranges), which (depending on system configuration) may be fatal to the
|
||||
host.
|
||||
|
||||
Note that to alter any of the bits collected together as
|
||||
PCI_COMMAND_GUEST permissive mode is now required to be enabled
|
||||
globally or on the specific device.
|
||||
|
||||
This is CVE-2015-2150 / XSA-120.

||||
