Starting from Linux 5.16 kernel, Tx timeout mechanism was added in the virtio_net driver which prints the "Tx timeout" warning message when a packet stays in Tx queue for too long. Below is an example of the reported message: "[494105.316739] virtio_net virtio1 tmfifo_net0: TX timeout on queue: 0, sq: output.0, vq: 0×1, name: output.0, usecs since last trans: 3079892256". This issue could happen when external host driver which drains the FIFO is restared, stopped or upgraded. To avoid such confusing "Tx timeout" messages, this commit adds logic to drop the outstanding Tx packet if it's not able to transmit in two seconds due to Tx FIFO full, which can be considered as congestion or out-of-resource drop. This commit also handles the special case that the packet is half- transmitted into the Tx FIFO. In such case, the packet is discarded with remaining length stored in vring->rem_padding. So paddings with zeros can be sent out when Tx space is available to maintain the integrity of the packet format. The padded packet will be dropped on the receiving side.

p2sb_bar() unhides P2SB device to get resources from the device. It guards the operation by locking pci_rescan_remove_lock so that parallel rescans do not find the P2SB device. However, this lock causes deadlock when PCI bus rescan is triggered by /sys/bus/pci/rescan. The rescan locks pci_rescan_remove_lock and probes PCI devices. When PCI devices call p2sb_bar() during probe, it locks pci_rescan_remove_lock again. Hence the deadlock. To avoid the deadlock, do not lock pci_rescan_remove_lock in p2sb_bar(). Instead, do the lock at fs_initcall. Introduce p2sb_cache_resources() for fs_initcall which gets and caches the P2SB resources. At p2sb_bar(), refer the cache and return to the caller. Before operating the device at P2SB DEVFN for resource cache, check that its device class is PCI_CLASS_MEMORY_OTHER 0x0580 that PCH specifications define. This avoids unexpected operation to other devices at the same DEVFN.

When booting a kernel with CONFIG_CFI_CLANG, there is a CFI failure when accessing any of the values under /sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00: $ cat /sys/devices/system/cpu/intel_uncore_frequency/package_00_die_00/max_freq_khz fish: Job 1, 'cat /sys/devices/system/cpu/int…' terminated by signal SIGSEGV (Address boundary error) $ sudo dmesg &| grep 'CFI failure' [ 170.953925] CFI failure at kobj_attr_show+0x19/0x30 (target: show_max_freq_khz+0x0/0xc0 [intel_uncore_frequency_common]; expected type: 0xd34078c5 The sysfs callback functions such as show_domain_id() are written as if they are going to be called by dev_attr_show() but as the above message shows, they are instead called by kobj_attr_show(). kCFI checks that the destination of an indirect jump has the exact same type as the prototype of the function pointer it is called through and fails when they do not. These callbacks are called through kobj_attr_show() because uncore_root_kobj was initialized with kobject_create_and_add(), which means uncore_root_kobj has a ->sysfs_ops of kobj_sysfs_ops from kobject_create(), which uses kobj_attr_show() as its ->show() value. The only reason there has not been a more noticeable problem until this point is that 'struct kobj_attribute' and 'struct device_attribute' have the same layout, so getting the callback from container_of() works the same with either value. Change all the callbacks and their uses to be compatible with kobj_attr_show() and kobj_attr_store(), which resolves the kCFI failure and allows the sysfs files to work properly.

When an legacy WMI event handler is removed, an WMI event could have called the handler just before it was removed, meaning the handler could still be running after wmi_remove_notify_handler() returns. Something similar could also happens when using the WMI bus, as the WMI core might still call the notify() callback from an WMI driver even if its remove() callback was just called. Fix this by introducing a rw semaphore which ensures that the event state of a WMI device does not change while the WMI core is handling an event for it. Tested on a Dell Inspiron 3505 and a Acer Aspire E1-731.

Until now, legacy WMI notify handler functions where using the wmi_block_list, which did no refcounting on the returned WMI device. This meant that the WMI device could disappear at any moment, potentially leading to various errors. Fix this by using bus_find_device() which returns an actual reference to the found WMI device.

Commit 58f6425e ("WMI: Cater for multiple events with same GUID") allowed legacy WMI notify handlers to be installed for multiple WMI devices with the same GUID. However this is useless since the legacy GUID-based interface is blacklisted from seeing WMI devices with duplicated GUIDs. Return immediately if a suitable WMI event is found in wmi_install/remove_notify_handler() since searching for other suitable events is pointless.

When wmi_install_notify_handler()/wmi_remove_notify_handler() are unable to enable/disable the WMI device, they unconditionally return an error to the caller. When registering legacy WMI notify handlers, this means that the callback remains registered despite wmi_install_notify_handler() having returned an error. When removing legacy WMI notify handlers, this means that the callback is removed despite wmi_remove_notify_handler() having returned an error. Fix this by only warning when the WMI device could not be enabled. This behaviour matches the bus-based WMI interface. Tested on a Dell Inspiron 3505 and a Acer Aspire E1-731.

bcachefs btree nodes are big - typically 256k - and btree roots are pinned in memory. As we're now up to 18 btrees, we now have significant memory overhead in mostly empty btree roots. And in the future we're going to start enforcing that certain btree node boundaries exist, to solve lock contention issues - analagous to XFS's AGIs. Thus, we need to start allocating smaller btree node buffers when we can. This patch changes code that refers to the filesystem constant c->opts.btree_node_size to refer to the btree node buffer size - btree_buf_bytes() - where appropriate.
