commit c50f11c upstream. Invalidating the buffer memory in arch_sync_dma_for_device() for FROM_DEVICE transfers When using the streaming DMA API to map a buffer prior to inbound non-coherent DMA (i.e. DMA_FROM_DEVICE), we invalidate any dirty CPU cachelines so that they will not be written back during the transfer and corrupt the buffer contents written by the DMA. This, however, poses two potential problems: (1) If the DMA transfer does not write to every byte in the buffer, then the unwritten bytes will contain stale data once the transfer has completed. (2) If the buffer has a virtual alias in userspace, then stale data may be visible via this alias during the period between performing the cache invalidation and the DMA writes landing in memory. Address both of these issues by cleaning (aka writing-back) the dirty lines in arch_sync_dma_for_device(DMA_FROM_DEVICE) instead of discarding them using invalidation.

commit 9c1e916 upstream. The current logic to assign the max packet limit for IN endpoints attempts to take the default HW value and apply the optimal endpoint settings based on it. However, if the default value reports a TxFIFO size large enough for only one max packet, it will divide the value and assign a smaller ep max packet limit. For example, if the default TxFIFO size fits 1024B, current logic will assign 1024/3 = 341B to ep max packet size. If function drivers attempt to request for an endpoint with a wMaxPacketSize of 1024B (SS BULK max packet size) then it will fail, as the gadget is unable to find an endpoint which can fit the requested size. Functionally, if the TxFIFO has enough space to fit one max packet, it will be sufficient, at least when initializing the endpoints.

commit 7ddda26 upstream. Commit 582ab24 ("usb: dwc3: pci: Set "linux,phy_charger_detect" property on some Bay Trail boards") added a new swnode similar to the existing ones for boards where the PHY handles charger detection. Unfortunately, the "linux,sysdev_is_parent" property got lost in the merge conflict resolution of commit ca9400e ("Merge 5.17-rc6 into usb-next"). Now dwc3_pci_intel_phy_charger_detect_properties is the only swnode in dwc3-pci that is missing "linux,sysdev_is_parent".

commit b337af3 upstream. In systemd systems setting a fixed MAC address through the "dev_addr" module argument fails systematically. When checking the MAC address after the interface is created it always has the same but different MAC address to the one supplied as argument. This is partially caused by systemd which by default will set an internally generated permanent MAC address for interfaces that are marked as having a randomly generated address. Commit 890d5b4 ("usb: gadget: u_ether: fix race in setting MAC address in setup phase") didn't take into account the fact that the interface must be marked as having a set MAC address when it's set as module argument. Fixed by marking the interface with NET_ADDR_SET when the "dev_addr" module argument is supplied.

commit be03b06 upstream. Not all LSR register flags are preserved across reads. Therefore, LSR readers must store the non-preserved bits into lsr_save_flags. This fix was initially mixed into feature commit f6f5861 ("serial: 8250: Handle UART without interrupt on TEMT using em485"). However, that feature change had a flaw and it was reverted to make room for simpler approach providing the same feature. The embedded fix got reverted with the feature change.

commit 928ea98 upstream. In fsl_mc_bus_remove(), mc->root_mc_bus_dev->mc_io is passed to fsl_destroy_mc_io(). However, mc->root_mc_bus_dev is already freed in fsl_mc_device_remove(). Then reference to mc->root_mc_bus_dev->mc_io triggers KASAN use-after-free. To avoid the use-after-free, keep the reference to mc->root_mc_bus_dev->mc_io in a local variable and pass to fsl_destroy_mc_io(). This patch needs rework to apply to kernels older than v5.15.

commit 168f912 upstream. When calling setattr_prepare() to determine the validity of the attributes the ia_{g,u}id fields contain the value that will be written to inode->i_{g,u}id. This is exactly the same for idmapped and non-idmapped mounts and allows callers to pass in the values they want to see written to inode->i_{g,u}id. When group ownership is changed a caller whose fsuid owns the inode can change the group of the inode to any group they are a member of. When searching through the caller's groups we need to use the gid mapped according to the idmapped mount otherwise we will fail to change ownership for unprivileged users. Consider a caller running with fsuid and fsgid 1000 using an idmapped mount that maps id 65534 to 1000 and 65535 to 1001. Consequently, a file owned by 65534:65535 in the filesystem will be owned by 1000:1001 in the idmapped mount. The caller now requests the gid of the file to be changed to 1000 going through the idmapped mount. In the vfs we will immediately map the requested gid to the value that will need to be written to inode->i_gid and place it in attr->ia_gid. Since this idmapped mount maps 65534 to 1000 we place 65534 in attr->ia_gid. When we check whether the caller is allowed to change group ownership we first validate that their fsuid matches the inode's uid. The inode->i_uid is 65534 which is mapped to uid 1000 in the idmapped mount. Since the caller's fsuid is 1000 we pass the check. We now check whether the caller is allowed to change inode->i_gid to the requested gid by calling in_group_p(). This will compare the passed in gid to the caller's fsgid and search the caller's additional groups. Since we're dealing with an idmapped mount we need to pass in the gid mapped according to the idmapped mount. This is akin to checking whether a caller is privileged over the future group the inode is owned by. And that needs to take the idmapped mount into account. Note, all helpers are nops without idmapped mounts. New regression test sent to xfstests.

Therefore, "start + size <= ac->ac_o_ex.fe_logical" may occur when the size is truncated. So start should be the start position of the group where ac_o_ex.fe_logical is located after alignment. In addition, when the value of fe_logical or EXT4_BLOCKS_PER_GROUP is very large, the value calculated by start_off is more accurate.

commit b55c3cd upstream. We capture a NULL pointer issue when resizing a corrupt ext4 image which is freshly clear resize_inode feature (not run e2fsck). It could be simply reproduced by following steps. The problem is because of the resize_inode feature was cleared, and it will convert the filesystem to meta_bg mode in ext4_resize_fs(), but the es->s_reserved_gdt_blocks was not reduced to zero, so could we mistakenly call reserve_backup_gdb() and passing an uninitialized resize_inode to it when adding new group descriptors. mkfs.ext4 /dev/sda 3G tune2fs -O ^resize_inode /dev/sda #forget to run requested e2fsck mount /dev/sda /mnt resize2fs /dev/sda 8G ======== BUG: kernel NULL pointer dereference, address: 0000000000000028 CPU: 19 PID: 3243 Comm: resize2fs Not tainted 5.18.0-rc7-00001-gfde086c5ebfd torvalds#748 ...

commit d52d165 upstream. On each vcpu load, we set the KVM_ARM64_HOST_SVE_ENABLED flag if SVE is enabled for EL0 on the host. This is used to restore the correct state on vpcu put. However, it appears that nothing ever clears this flag. Once set, it will stick until the vcpu is destroyed, which has the potential to spuriously enable SVE for userspace. We probably never saw the issue because no VMM uses SVE, but that's still pretty bad. Unconditionally clearing the flag on vcpu load addresses the issue.

commit 2cdea19 upstream. Since 5bfa685 ("KVM: arm64: vgic: Read HW interrupt pending state from the HW"), we're able to source the pending bit for an interrupt that is stored either on the physical distributor or on a device. However, this state is only available when the vcpu is loaded, and is not intended to be accessed from userspace. Unfortunately, the GICv2 emulation doesn't provide specific userspace accessors, and we fallback with the ones that are intended for the guest, with fatal consequences. Add a new vgic_uaccess_read_pending() accessor for userspace to use, build on top of the existing vgic_mmio_read_pending().

commit 7e41528 upstream. GCC 12 enhanced -Waddress when comparing array address to null [0], which warns: drivers/virtio/virtio_pci_common.c: In function ‘vp_del_vqs’: drivers/virtio/virtio_pci_common.c:257:29: warning: the comparison will always evaluate as ‘true’ for the pointer operand in ‘vp_dev->msix_affinity_masks + (sizetype)((long unsigned int)i * 256)’ must not be NULL [-Waddress] 257 | if (vp_dev->msix_affinity_masks[i]) | ^~~~~~ In fact, the verification is comparing the result of a pointer arithmetic, the address "msix_affinity_masks + i", which will always evaluate to true. Under the hood, free_cpumask_var() calls kfree(), which is safe to pass NULL, not requiring non-null verification. So remove the verification to make compiler happy (happy compiler, happy life).

All tests passed on gaze15 running 22.04. gaze15-22.04-5.18.8-kernel-tests.txt Note: master was needed for the newest 470 driver |

Dependency error installing 470 on gaze15 running 20.04. Running Error: Other than this issue all testing passed for 20.04 on the gaze15. |

So far, this is looking good on:
However, there is an issue with the Galp5-3050 with the 515.48 Nvidia Driver: In hybrid mode, Steam is regularly locking up, and impacting other system functions (for example, passing I'm cross-testing with Ubuntu to try and limit the footprint for possible issues. It seems Galp5 specific, at the Gaze17 is happy in all three graphics modes to run Steam/Games with all three current driver versions (470.129, 510.73, and 515.48) |
|
470.129 is working with this Kernel. We'll need to ensure that it is released alongside the Kernel though, as the current 470 release will not successfully build kernel modules with 5.18.x |
470.129 was released earlier today: pop-os/repo-release#144 |
|
All testing on darp6 22.04 passed. |

Aquantia Ethernet is fine with this kernel btw. I was able to test it on my desktop at home. |

The galp5-1650Ti was unable to wake from suspend when in Nvidia mode while using either Pop or Ubuntu 22.04. I tried reinstalling the OS 3 times each, with little success. I was able to get the 3rd install of Pop 22.04 to suspend a couple times. But, it too failed to wake from suspend a couple times during testing. Aside from the suspend behavior, I was able to make it through all other testing. Hybrid mode was even able to reliably wake from suspend. I believe we are going to wait for an updated release at this time, but this was what I saw on my galp5 |

There was a problem hiding this comment.
So, QA is suspending testing on this Kernel release outside of diagnostic testing.
So far, we've noticed the following issues:
- On Galp5-3050 w/ Nvidia-515, Steam locks up in hybrid mode, and also effects other processes in terms of slowing their execution.
- On Galp5-1650, the machine will not resume in dedicated graphics mode, though it will in Integrated, Hybrid, and Compute modes.
- With Ubuntu 22.04 and Nvidia-515, a usable session cannot be reached on boot.

[ Upstream commit 0fe6ee8 ] 2d186af ("profiling: fix shift-out-of-bounds bugs") limits shift value by [0, BITS_PER_LONG -1], which means [0, 63]. However, syzbot found that the max shift value should be the bit number of (_etext - _stext). If shift is outside of this, the "buffer_bytes" will be zero and will cause kzalloc(0). Then the kernel panics due to dereferencing the returned pointer 16. This can be easily reproduced by passing a large number like 60 to enable profiling and then run readprofile.
