usb: gadget: u_ether: fix regression in setting fixed MAC address

2022-06-25T10:44:35+00:00

commit b337af3a4d6147000b7ca6b3438bf5c820849b37 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 890d5b40908bfd1a ("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.

dm: remove special-casing of bio-based immutable singleton target on NVMe

2022-06-25T10:44:35+00:00

Commit 9c37de297f6590937f95a28bec1b7ac68a38618f upstream. There is no benefit to DM special-casing NVMe. Remove all code used to establish DM_TYPE_NVME_BIO_BASED. Also, remove 3 'struct mapped_device *md' variables in __map_bio() which masked the same variable that is available within __map_bio()'s scope.

virtio-pci: Remove wrong address verification in vp_del_vqs()

2022-06-22T12:11:24+00:00

commit 7e415282b41bf0d15c6e0fe268f822d9b083f2f7 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).

dm mirror log: round up region bitmap size to BITS_PER_LONG

2022-06-22T12:11:23+00:00

commit 85e123c27d5cbc22cfdc01de1e2ca1d9003a02d0 upstream. The code in dm-log rounds up bitset_size to 32 bits. It then uses find_next_zero_bit_le on the allocated region. find_next_zero_bit_le accesses the bitmap using unsigned long pointers. So, on 64-bit architectures, it may access 4 bytes beyond the allocated size. Fix this bug by rounding up bitset_size to BITS_PER_LONG. This bug was found by running the lvm2 testsuite with kasan.

serial: 8250: Store to lsr_save_flags after lsr read

2022-06-22T12:11:23+00:00

commit be03b0651ffd8bab69dfd574c6818b446c0753ce 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 f6f586102add ("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. Re-add the lsr_save_flags fix and properly mark it's a fix.

usb: gadget: lpc32xx_udc: Fix refcount leak in lpc32xx_udc_probe

commit 4757c9ade34178b351580133771f510b5ffcf9c8 upstream. of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak. of_node_put() will check NULL pointer.
