commit 44117a1d upstream. setserial changes the IRQ via uart_set_info(). It invokes uart_shutdown() which free the current used IRQ and clear TTY_PORT_INITIALIZED. It will then update the IRQ number and invoke uart_startup() before returning to the caller leaving TTY_PORT_INITIALIZED cleared. The next open will crash with | list_add double add: new=ffffffff839fcc98, prev=ffffffff839fcc98, next=ffffffff839fcc98. since the close from the IOCTL won't free the IRQ (and clean the list) due to the TTY_PORT_INITIALIZED check in uart_shutdown(). There is same pattern in uart_do_autoconfig() and I *think* it also needs to set TTY_PORT_INITIALIZED there. Is there a reason why uart_startup() does not set the flag by itself after the IRQ has been acquired (since it is cleared in uart_shutdown)? Signed-off-by:

The 4.9.77 version of "x86/pti/efi: broken conversion from efi to kernel page table" looked nicer than the 4.4.112 version, but was suboptimal on machines booted with "pti=off" (or on AMD machines): it allocated pgd with an order 1 page whatever the setting of kaiser_enabled. Fix that by moving the definition of PGD_ALLOCATION_ORDER from asm/pgalloc.h to asm/pgtable.h, which already defines kaiser_enabled.

commit 445b69e3 upstream The inital fix for trusted boot and PTI potentially misses the pgd clearing if pud_alloc() sets a PGD. It probably works in *practice* because for two adjacent calls to map_tboot_page() that share a PGD entry, the first will clear NX, *then* allocate and set the PGD (without NX clear). The second call will *not* allocate but will clear the NX bit. Defer the NX clearing to a point after it is known that all top-level allocations have occurred. Add a comment to clarify why. [ tglx: Massaged changelog ] [ hughd notes: I have not tested tboot, but this looks to me as necessary and as safe in old-Kaiser backports as it is upstream; I'm not submitting the commit-to-be-fixed 262b6b30, since it was undone by 445b69e3, and makes conflict trouble because of 5-level's p4d versus 4-level's pgd.] Fixes: 262b6b30 ("x86/tboot: Unbreak tboot with PTI enabled") Signed-off-by:

Vince reported perf_fuzzer quickly locks up on 4.15-rc7 with PTI; Robert reported Bad RIP with KPTI and Intel BTS also on 4.15-rc7: honggfuzz -f /tmp/somedirectorywithatleastonefile \ --linux_perf_bts_edge -s -- /bin/true (honggfuzz from https://github.com/google/honggfuzz) crashed with BUG: unable to handle kernel paging request at ffff9d3215100000 (then narrowed it down to perf record --per-thread -e intel_bts//u -- /bin/ls). The intel_bts driver does not use the 'normal' BTS buffer which is exposed through kaiser_add_mapping(), but instead uses the memory allocated for the perf AUX buffer. This obviously comes apart when using PTI, because then the kernel mapping, which includes that AUX buffer memory, disappears while switched to user page tables. Easily fixed in old-Kaiser backports, by applying kaiser_add_mapping() to those pages; perhaps not so easy for upstream, where 4.15-rc8 commit 99a9dc98 ("x86,perf: Disable intel_bts when PTI") disables for now. Slightly reorganized surrounding code in bts_buffer_setup_aux(), so it can better match bts_buffer_free_aux(): free_aux with an #ifdef to avoid the loop when PTI is off, but setup_aux needs to loop anyway (and kaiser_add_mapping() is cheap when PTI config is off or "pti=off").

commit fd6e440f upstream. The recent commit 87590ce6 ("sysfs/cpu: Add vulnerability folder") added a generic folder and set of files for reporting information on CPU vulnerabilities. One of those was for meltdown: /sys/devices/system/cpu/vulnerabilities/meltdown This commit wires up that file for 64-bit Book3S powerpc. For now we default to "Vulnerable" unless the RFI flush is enabled. That may not actually be true on all hardware, further patches will refine the reporting based on the CPU/platform etc. But for now we default to being pessimists. Signed-off-by:

commit bc9c9304 upstream. Because there may be some performance overhead of the RFI flush, add kernel command line options to disable it. We add a sensibly named 'no_rfi_flush' option, but we also hijack the x86 option 'nopti'. The RFI flush is not the same as KPTI, but if we see 'nopti' we can guess that the user is trying to avoid any overhead of Meltdown mitigations, and it means we don't have to educate every one about a different command line option.

commit aa8a5e00 upstream. On some CPUs we can prevent the Meltdown vulnerability by flushing the L1-D cache on exit from kernel to user mode, and from hypervisor to guest. This is known to be the case on at least Power7, Power8 and Power9. At this time we do not know the status of the vulnerability on other CPUs such as the 970 (Apple G5), pasemi CPUs (AmigaOne X1000) or Freescale CPUs. As more information comes to light we can enable this, or other mechanisms on those CPUs. The vulnerability occurs when the load of an architecturally inaccessible memory region (eg. userspace load of kernel memory) is speculatively executed to the point where its result can influence the address of a subsequent speculatively executed load. In order for that to happen, the first load must hit in the L1, because before the load is sent to the L2 the permission check is performed. Therefore if no kernel addresses hit in the L1 the vulnerability can not occur. We can ensure that is the case by flushing the L1 whenever we return to userspace. Similarly for hypervisor vs guest. In order to flush the L1-D cache on exit, we add a section of nops at each (h)rfi location that returns to a lower privileged context, and patch that with some sequence. Newer firmwares are able to advertise to us that there is a special nop instruction that flushes the L1-D. If we do not see that advertised, we fall back to doing a displacement flush in software. For guest kernels we support migration between some CPU versions, and different CPUs may use different flush instructions. So that we are prepared to migrate to a machine with a different flush instruction activated, we may have to patch more than one flush instruction at boot if the hypervisor tells us to. In the end this patch is mostly the work of Nicholas Piggin and Michael Ellerman. However a cast of thousands contributed to analysis of the issue, earlier versions of the patch, back ports testing etc. Many thanks to all of them. Tested-by:

commit 50e51c13 upstream. The rfid/hrfid ((Hypervisor) Return From Interrupt) instruction is used for switching from the kernel to userspace, and from the hypervisor to the guest kernel. However it can and is also used for other transitions, eg. from real mode kernel code to virtual mode kernel code, and it's not always clear from the code what the destination context is. To make it clearer when reading the code, add macros which encode the expected destination context. Signed-off-by:

Upstream commit 1c9de5bf ("usbip: vhci-hcd: Add USB3 SuperSpeed support") vhci_hcd clears all the bits port_status bits instead of clearing just the USB_PORT_STAT_POWER bit when it handles ClearPortFeature: USB_PORT_FEAT_POWER. This causes vhci_hcd attach to fail in a bad state, leaving device unusable by the client. The device is still attached and however client can't use it. The problem was fixed as part of larger change to add USB3 Super Speed support. This patch backports just the change to clear the USB_PORT_STAT_POWER. Signed-off-by:

commit cbeef22f upstream. Quoting Hans: If we return 1 from our post_reset handler, then our disconnect handler will be called immediately afterwards. Since pre_reset blocks all scsi requests our disconnect handler will then hang in the scsi_remove_host call. This is esp. bad because our disconnect handler hanging for ever also stops the USB subsys from enumerating any new USB devices, causes commands like lsusb to hang, etc. In practice this happens when unplugging some uas devices because the hub code may see the device as needing a warm-reset and calls usb_reset_device before seeing the disconnect. In this case uas_configure_endpoints fails with -ENODEV. We do not want to print an error for this, so this commit also silences the shost_printk for -ENODEV. ENDQUOTE However, if we do that we better drop any unconditional execution and report to the SCSI subsystem that we have undergone a reset but we are not operational now. Signed-off-by:

commit ce5bf9a5 upstream. Upon usb composition switch there is possibility of ep0 file release happening after gadget driver bind. In case of composition switch from adb to a non-adb composition gadget will never gets bound again resulting into failure of usb device enumeration. Fix this issue by checking FFS_FL_BOUND flag and avoid extra gadget driver unbind if it is already done as part of composition switch.
