- Add a mitigation for the attack vector of interrupting the saferet sequence used in the SRSO mitigation and still poisoning the RSB. Do that by emulating the saferet sequence and thus avoiding executing a RET instruction. * tag 'x86_bugs_saferet' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/bugs: Make Safe-RET robust against interrupt injection

s390/pci: Fix s390_pci_mmio_write syscall error return without MIO

2026-07-31T11:31:19+00:00

On a machine without PCI memory-I/O (MIO) support or when running with pci=nomio the s390 specific PCI MMIO write syscall checks if the MMIO cookie is above ZPCI_IOMAP_ADDR_BASE as a sanity check before even trying to perform the MMIO. If this check fails the return value was left unchanged and thus 0 from prior operations falsely indicating success. This could potentially confuse user-space into falsely believing the MMIO, on a mapping not valid for MMIO was successful. Fix this by setting the return value to -EFAULT prior to the check following the same pattern as elsewhere in the same function.
