2022-11-29drm/i915/mtl: Fix dram info readoutRadhakrishna Sripada
MEM_SS_INFO_GLOBAL Register info read from the hardware is cached in val. However the variable is being modified when determining the DRAM type thereby clearing out the channels and qgv info extracted later in the function xelpdp_get_dram_info. Preserve the register value and use extracted fields in the switch statement.

2022-11-28afs: Fix fileserver probe RTT handlingDavid Howells
The fileserver probing code attempts to work out the best fileserver to use for a volume by retrieving the RTT calculated by AF_RXRPC for the probe call sent to each server and comparing them. Sometimes, however, no RTT estimate is available and rxrpc_kernel_get_srtt() returns false, leading good fileservers to be given an RTT of UINT_MAX and thus causing the rotation algorithm to ignore them. Fix afs_select_fileserver() to ignore rxrpc_kernel_get_srtt()'s return value and just take the estimated RTT it provides - which will be capped at 1 second.

I got the following report while doing device(mscc-miim) load test with CONFIG_OF_UNITTEST and CONFIG_OF_DYNAMIC enabled: OF: ERROR: memory leak, expected refcount 1 instead of 2, of_node_get()/of_node_put() unbalanced - destroy cset entry: attach overlay node /spi/soc@0/mdio@7107009c/ethernet-phy@0 If the 'fwnode' is not an acpi node, the refcount is get in fwnode_mdiobus_phy_device_register(), but it has never been put when the device is freed in the normal path. So call fwnode_handle_put() in phy_device_release() to avoid leak.

2022-11-28mptcp: don't orphan ssk in mptcp_close()Menglong Dong
All of the subflows of a msk will be orphaned in mptcp_close(), which means the subflows are in DEAD state. After then, DATA_FIN will be sent, and the other side will response with a DATA_ACK for this DATA_FIN. However, if the other side still has pending data, the data that received on these subflows will not be passed to the msk, as they are DEAD and subflow_data_ready() will not be called in tcp_data_ready(). Therefore, these data can't be acked, and they will be retransmitted again and again, until timeout. Fix this by setting ssk->sk_socket and ssk->sk_wq to 'NULL', instead of orphaning the subflows in __mptcp_close(), as Paolo suggested.

2022-11-28ipv4: Fix route deletion when nexthop info is not specifiedIdo Schimmel
When the kernel receives a route deletion request from user space it tries to delete a route that matches the route attributes specified in the request. If only prefix information is specified in the request, the kernel should delete the first matching FIB alias regardless of its associated FIB info. However, an error is currently returned when the FIB info is backed by a nexthop object: # ip nexthop add id 1 via 192.0.2.2 dev dummy10 # ip route add 198.51.100.0/24 nhid 1 # ip route del 198.51.100.0/24 RTNETLINK answers: No such process Fix by matching on such a FIB info when legacy nexthop attributes are not specified in the request. An earlier check already covers the case where a nexthop ID is specified in the request. Add tests that cover these flows. Before the fix: # ./fib_nexthops.sh -t ipv4_fcnal ... TEST: Delete route when not specifying nexthop attributes [FAIL] Tests passed: 11 Tests failed: 1 After the fix: # ./fib_nexthops.sh -t ipv4_fcnal ...

2022-11-28riscv: Sync efi page table's kernel mappings before switchingAlexandre Ghiti
The EFI page table is initially created as a copy of the kernel page table. With VMAP_STACK enabled, kernel stacks are allocated in the vmalloc area: if the stack is allocated in a new PGD (one that was not present at the moment of the efi page table creation or not synced in a previous vmalloc fault), the kernel will take a trap when switching to the efi page table when the vmalloc kernel stack is accessed, resulting in a kernel panic. Fix that by updating the efi kernel mappings before switching to the efi page table.

2022-11-28pinctrl: intel: Save and restore pins in "direct IRQ" modeAndy Shevchenko
The firmware on some systems may configure GPIO pins to be an interrupt source in so called "direct IRQ" mode. In such cases the GPIO controller driver has no idea if those pins are being used or not. At the same time, there is a known bug in the firmwares that don't restore the pin settings correctly after suspend, i.e. by an unknown reason the Rx value becomes inverted. Hence, let's save and restore the pins that are configured as GPIOs in the input mode with GPIROUTIOXAPIC bit set.

2022-11-28irqchip/irq-mtk-cirq: Add support for System CIRQ on MT8192AngeloGioacchino Del Regno
On some SoCs the System CIRQ register layout is slightly different, as there are more registers per function and in some cases other differences later in the layout: this is seen on at least MT8192, but it's also valid for some other "contemporary" SoCs both for Chromebooks and for smartphones. Add the new "v2" register layout and use it if the compatible "mediatek,mt8192-cirq" is found.

2022-11-28irqchip/irq-mtk-cirq: Move register offsets to const arrayAngeloGioacchino Del Regno
In preparation to add support for new SoCs having a different register layout, add an enumeration that documents register offsets and move the definitions for the same to a u32 array; Selecting the right register offsets array is done by adding an of_device_id array containing all of the currently supported compatible strings pointing to the "v1" offsets array (as data): since no devicetree declares the `mediatek,mtk-cirq` compatible without a SoC-specific one, it wasn't necessary to provide any legacy fallback. Every usage of the aforemementioned definitions was changed to get a register address through a newly introduced `mtk_cirq_reg()` accessor. This change brings no functional changes.

Migrate mediatek,cirq.txt to dt schema as mediatek,mtk-cirq.yaml.

Little rewording on property descriptions also happened for them to be more concise.

2022-11-28net: wwan: iosm: fix incorrect skb lengthM Chetan Kumar
skb passed to network layer contains incorrect length. In mux aggregation protocol, the datagram block received from device contains block signature, packet & datagram header. The right skb len to be calculated by subracting datagram pad len from datagram length. Whereas in mux lite protocol, the skb contains single datagram so skb len is calculated by subtracting the packet offset from datagram header.

Tim Harvey reports that link modes which he does not expect to be supported are being advertised, and this is because of the workaround we have for PHYs that switch interface modes. Fix this up by checking whether rate matching will be used for the requested interface mode, and if rate matching will be used, perform validation only with the requested interface mode, rather than invoking this workaround.

2022-11-28gpiolib: fix memory leak in gpiochip_setup_dev()Zeng Heng
Here is a backtrace report about memory leak detected in gpiochip_setup_dev(): unreferenced object 0xffff88810b406400 (size 512): comm "python3", pid 1682, jiffies 4295346908 (age 24.090s) backtrace: kmalloc_trace device_add device_private_init at drivers/base/core.c:3361 (inlined by) device_add at drivers/base/core.c:3411 cdev_device_add gpiolib_cdev_register gpiochip_setup_dev gpiochip_add_data_with_key gcdev_register() & gcdev_unregister() would call device_add() & device_del() (no matter CONFIG_GPIO_CDEV is enabled or not) to register/unregister device. However, if device_add() succeeds, some resource (like struct device_private allocated by device_private_init()) is not released by device_del(). Therefore, after device_add() succeeds by gcdev_register(), it needs to call put_device() to release resource in the error handle path. Here we move forward the register of release function, and let it release every piece of resource by put_device() instead of kfree(). While at it, fix another subtle issue, i.e. when gc->ngpio is equal to 0, we still call kcalloc() and, in case of further error, kfree() on the ZERO_PTR pointer, which is not NULL. It's not a bug per se, but rather waste of the resources and potentially wrong expectation about contents of the gdev->descs variable.
