x86/amd_nb: Use rdmsr_safe() in amd_get_mmconfig_range()

5.5 MediumFix available

In the Linux kernel, the following vulnerability has been resolved:

x86/amd_nb: Use rdmsr_safe() in amd_get_mmconfig_range()

Xen doesn't offer MSR_FAM10H_MMIO_CONF_BASE to all guests. This results in the following warning:

based on quirks for a "PNP0c01" device. Treating MMCFG as disabled is the right course of action, so no change is needed there.

This was most likely exposed by fixing the Xen MSR accessors to not be silently-safe.

When the network namespace is deleted, the net structureaccessed by tcp s timer handler function causes problems.To fix this problem, let s hold netns refcnt for the tcp kernel socket asdone in other modules. This is an ugly hack which can easily be backportedto earlier kernels. A proper fix which cleans up the interfaces willfollow, but may not be so easy to backport.(CVE-2024-53168)
