[PATCH 2/3] acpi/processor: sanitize _PDC buffer bits when running as Xen dom0

by Roger Pau Monne

The Processor _PDC buffer bits notify ACPI of the OS capabilities, and so ACPI can adjust the return of other Processor methods taking the OS capabilities into account. When Linux is running as a Xen dom0, it's the hypervisor the entity in charge of processor power management, and hence Xen needs to make sure the capabilities reported in the _PDC buffer match the capabilities of the driver in Xen. Introduce a small helper to sanitize the buffer when running as Xen dom0.

[PATCH v7] tty: fix hang on tty device with no_room set

by juanfengpy＠gmail.com

From: Hui Li <caelli(a)tencent.com> We have met a hang on pty device, the reader was blocking at epoll on master side, the writer was sleeping at wait_woken inside n_tty_write on slave side, and the write buffer on tty_port was full, we found that the reader and writer would never be woken again and blocked forever. The problem was caused by a race between reader and kworker: n_tty_read(reader): n_tty_receive_buf_common(kworker): copy_from_read_buf()| |room = N_TTY_BUF_SIZE - (ldata->read_head - tail) |room <= 0 n_tty_kick_worker() | |ldata->no_room = true After writing to slave device, writer wakes up kworker to flush data on tty_port to reader, and the kworker finds that reader has no room to store data so room <= 0 is met. At this moment, reader consumes all the data on reader buffer and calls n_tty_kick_worker to check ldata->no_room which is false and reader quits reading. Then kworker sets ldata->no_room=true and quits too. If write buffer is not full, writer will wake kworker to flush data again after following writes, but if write buffer is full and writer goes to sleep, kworker will never be woken again and tty device is blocked. This problem can be solved with a check for read buffer size inside n_tty_receive_buf_common, if read buffer is empty and ldata->no_room is true, a call to n_tty_kick_worker is necessary to keep flushing data to reader.

[PATCH v3 4/6] Revert "PCI: hv: Fix a timing issue which causes kdump to fail occasionally"

by Dexuan Cui

This reverts commit d6af2ed29c7c1c311b96dac989dcb991e90ee195. The statement "the hv_pci_bus_exit() call releases structures of all its child devices" in commit d6af2ed29c7c is not true: in the path hv_pci_probe() -> hv_pci_enter_d0() -> hv_pci_bus_exit(hdev, true): the parameter "keep_devs" is true, so hv_pci_bus_exit() does *not* release the child "struct hv_pci_dev *hpdev" that is created earlier in pci_devices_present_work() -> new_pcichild_device(). The commit d6af2ed29c7c was originally made in July 2020 for RHEL 7.7, where the old version of hv_pci_bus_exit() was used; when the commit was rebased and merged into the upstream, people didn't notice that it's not really necessary. The commit itself doesn't cause any issue, but it makes hv_pci_probe() more complicated. Revert it to facilitate some upcoming changes to hv_pci_probe().

[PATCH v3 2/6] PCI: hv: Fix a race condition in hv_irq_unmask() that can cause panic

by Dexuan Cui

When the host tries to remove a PCI device, the host first sends a PCI_EJECT message to the guest, and the guest is supposed to gracefully remove the PCI device and send a PCI_EJECTION_COMPLETE message to the host; the host then sends a VMBus message CHANNELMSG_RESCIND_CHANNELOFFER to the guest (when the guest receives this message, the device is already unassigned from the guest) and the guest can do some final cleanup work; if the guest fails to respond to the PCI_EJECT message within one minute, the host sends the VMBus message CHANNELMSG_RESCIND_CHANNELOFFER and removes the PCI device forcibly. In the case of fast device addition/removal, it's possible that the PCI device driver is still configuring MSI-X interrupts when the guest receives the PCI_EJECT message; the channel callback calls hv_pci_eject_device(), which sets hpdev->state to hv_pcichild_ejecting, and schedules a work hv_eject_device_work(); if the PCI device driver is calling pci_alloc_irq_vectors() -> ... -> hv_compose_msi_msg(), we can break the while loop in hv_compose_msi_msg() due to the updated hpdev->state, and leave data->chip_data with its default value of NULL; later, when the PCI device driver calls request_irq() -> ... -> hv_irq_unmask(), the guest crashes in hv_arch_irq_unmask() due to data->chip_data being NULL. Fix the issue by not testing hpdev->state in the while loop: when the guest receives PCI_EJECT, the device is still assigned to the guest, and the guest has one minute to finish the device removal gracefully. We don't really need to (and we should not) test hpdev->state in the loop.

[REGRESSION] Asus X541UAK hangs on suspend and poweroff (v6.1.6 onward)

Hi there, hello, Sometimes when I suspend (by closing the lid, less often - by pressing Fn+F1 (sleep key combo)) or poweroff my laptop (both by pressing powerit button and running "loginctl poweroff"), it goes in such a state when it doesn't respond to opening/closing the lid, power button nor Ctrl+Alt+Del, but, unlike in sleep mode, the fan is rotating and the "awake status" LED is on.

I used that fork until 6.2-pf2, but since then (early March) moved to vanilla sources and started following the 6.1.y branch when it was declared LTS. And the issue was present on all of them. The hang was last detected 3 days ago on 6.1.22 and today on 6.1.23. I'd like to bisect it, but it could take ages for a couple of reasons: 1) I don't know exact patterns it follows. One of the scenarios I've noticed was this one (sorry if too ridiculous): - put the laptop on the nearby couch and simultaneously close the lid; the loose charger jack might disconnect; - lay the mouse upside down (so it doesn't wake up when I reconnect the charger), but it's not a 100% guarantee of the bug and, as I said earlier, the laptop also misbehaves on shutdown. 2) The issue happens rarely, once in a few days (sometimes up to a week; I haven't measured it precisely back then).

[PATCH v1 1/5] hostfs: Fix ephemeral inodes

by Mickaël Salaün

hostfs creates a new inode for each opened or created file, which created useless inode allocations and forbade identifying a host file with a kernel inode. Fix this uncommon filesystem behavior by tying kernel inodes to host file's inode and device IDs. Even if the host filesystem inodes may be recycled, this cannot happen while a file referencing it is open, which is the case with hostfs. It should be noted that hostfs inode IDs may not be unique for the same hostfs superblock because multiple host's (backed) superblocks may be used. Delete inodes when dropping them to force backed host's file descriptors closing. This enables to entirely remove ARCH_EPHEMERAL_INODES, and then makes Landlock fully supported by UML. This is very useful for testing (ongoing and backported) changes. These changes also factor out and simplify some helpers thanks to the new hostfs_inode_update() and the hostfs_iget() revamp: read_name(), hostfs_create(), hostfs_lookup(), hostfs_mknod(), and hostfs_fill_sb_common(). A following commit with new Landlock tests check this new hostfs inode consistency.
