[ Upstream commit ebcc5928 ] Since GCC 9, the compiler warns about evolution of the platform-specific ABI, in particular relating for the marshaling of certain structures involving bitfields. The kernel is a standalone binary, and of course nobody would be so stupid as to expose structs containing bitfields as function arguments in ABI. (Passing a pointer to such a struct, however inadvisable, should be unaffected by this change. perf and various drivers rely on that.) So these warnings do more harm than good: turn them off. We may miss warnings about future ABI drift, but that's too bad. Future ABI breaks of this class will have to be debugged and fixed the traditional way unless the compiler evolves finer-grained diagnostics. Signed-off-by:

[ Upstream commit 4a60570d ] Some chips have attributes which exist on more than one page but the attribute is not presently marked as paged. This causes the attributes to be generated with the same label, which makes it impossible for userspace to tell them apart. Marking all such attributes as paged would result in the page suffix being added regardless of whether they were present on more than one page or not, which might break existing setups. Therefore, we add a second check which treats the attribute as paged, even if not marked as such, if it is present on multiple pages.

[ Upstream commit c41dd48e ] Drivers may register to hwmon and request for also registering with the thermal subsystem (HWMON_C_REGISTER_TZ). However, some of these driver, e.g. marvell phy, may be probed from Device Tree or being dynamically allocated, and in the later case, it will not have a dev->of_node entry. Registering with hwmon without the dev->of_node may result in different outcomes depending on the device tree, which may be a bit misleading. If the device tree blob has no 'thermal-zones' node, the *hwmon_device_register*() family functions are going to gracefully succeed, because of-thermal, *thermal_zone_of_sensor_register() return -ENODEV in this case, and the hwmon error path handles this error code as success to cover for the case where CONFIG_THERMAL_OF is not set. However, if the device tree blob has the 'thermal-zones' entry, the *hwmon_device_register*() will always fail on callers with no dev->of_node, propagating -EINVAL. If dev->of_node is not present, calling of-thermal does not make sense. For this reason, this patch checks first if the device has a of_node before going over the process of registering with the thermal subsystem of-thermal interface. And in this case, when a caller of *hwmon_device_register*() with HWMON_C_REGISTER_TZ and no dev->of_node will still register with hwmon, but not with the thermal subsystem. If all the hwmon part bits are in place, the registration will succeed.

[ Upstream commit 33572619 ] Enabling sysfs attribute bridge_hostnotify triggers a series of udev events for the MAC addresses of all currently connected peers. In case no VLAN is set for a peer, the device reports the corresponding MAC addresses with VLAN ID 4096. This currently results in attribute VLAN=4096 for all non-VLAN interfaces in the initial series of events after host-notify is enabled. Instead, no VLAN attribute should be reported in the udev event for non-VLAN interfaces. Only the initial events face this issue. For dynamic changes that are reported later, the device uses a validity flag. This also changes the code so that it now sets the VLAN attribute for MAC addresses with VID 0. On Linux, no qeth interface will ever be registered with VID 0: Linux kernel registers VID 0 on all network interfaces initially, but qeth will drop .ndo_vlan_rx_add_vid for VID 0. Peers with other OSs could register MACs with VID 0. Fixes: 9f48b9db ("qeth: bridgeport support - address notifications") Signed-off-by:

[ Upstream commit 0cd6783d ] While qeth_l3 uses netif_keep_dst() to hold onto the dst, a skb's dst may still have been obsoleted (via dst_dev_put()) by the time that we end up using it. The dst then points to the loopback interface, which means the neighbour lookup in qeth_l3_get_cast_type() determines a bogus cast type of RTN_BROADCAST. For IQD interfaces this causes us to place such skbs on the wrong HW queue, resulting in TX errors. Fix-up the various call sites to first validate the dst entry with dst_check(), and fall back accordingly. Signed-off-by:

[ Upstream commit 72c87976 ] When selecting the cast type of a neighbourless IPv4 skb (eg. on a raw socket), qeth_l3 falls back to the packet's destination IP address. For this case we should classify traffic sent to 255.255.255.255 as broadcast. This fixes DHCP requests, which were misclassified as unicast (and for IQD interfaces thus ended up on the wrong HW queue). Signed-off-by:

[ Upstream commit 3562f5d9 ] The WRITE ZEROES command has no data transfer so that we need to initialize the struct (nvmet_req *req)->data_len to 0x0. While (nvmet_req *req)->transfer_len is initialized in nvmet_req_init(), data_len will be initialized by nowhere which might cause the failure with status code NVME_SC_SGL_INVALID_DATA | NVME_SC_DNR randomly. It's because nvmet_req_execute() checks like: if (unlikely(req->data_len != req->transfer_len)) { req->error_loc = offsetof(struct nvme_common_command, dptr); nvmet_req_complete(req, NVME_SC_SGL_INVALID_DATA | NVME_SC_DNR); } else req->execute(req); This patch fixes req->data_len not to be a randomly assigned by initializing it to 0x0 when preparing the command in nvmet_bdev_parse_io_cmd(). nvmet_file_parse_io_cmd() which is for file-backed I/O has already initialized the data_len field to 0x0, though.

[ Upstream commit 1c810739 ] On the Arm Juno platform, the HDLCD pixel clock is constrained to 250KHz resolution in order to avoid the tiny System Control Processor spending aeons trying to calculate exact PLL coefficients. This means that modes like my oddball 1600x1200 with 130.89MHz clock get rejected since the rate cannot be matched exactly. In practice, though, this mode works quite happily with the clock at 131MHz, so let's relax the check to allow a little bit of slop. Signed-off-by:

[ Upstream commit b96151ed ] Rather than allowing any old mode through, then subsequently refusing unmatchable clock rates in atomic_check when it's too late to back out and pick a different mode, let's do that validation up-front where it will cause unsupported modes to be correctly pruned in the first place. This also eliminates an issue whereby a perceived clock rate of 0 would cause atomic disable to fail and prevent the module from being unloaded. Signed-off-by:
