[ Upstream commit 39714fd7 ] Make pci_dev_is_disconnected() public so that it can be called from Intel VT-d driver to quickly fix/workaround the surprise removal unplug hang issue for those ATS capable devices on PCIe switch downstream hotplug capable ports. Beside pci_device_is_present() function, this one has no config space space access, so is light enough to optimize the normal pure surprise removal and safe removal flow. Acked-by:

[ Upstream commit aaa87363 ] When building with CONFIG_XEN_PV=y, .text symbols are emitted into the .notes section so that Xen can find the "startup_xen" entry point. This information is used prior to booting the kernel, so relocations are not useful. In fact, performing relocations against the .notes section means that the KASLR base is exposed since /sys/kernel/notes is world-readable. To avoid leaking the KASLR base without breaking unprivileged tools that are expecting to read /sys/kernel/notes, skip performing relocations in the .notes section. The values readable in .notes are then identical to those found in System.map. Reported-by:

[ Upstream commit 793551c9 ] It is generally invalid to fail a Device Check notification if the scan handler has not been attached to the given device after a bus rescan, because there may be valid reasons for the scan handler to refuse attaching to the device (for example, the device is not ready). For this reason, modify acpi_scan_device_check() to return 0 in that case without printing a warning.

[ Upstream commit 79978bff ] We identified that the PHYs actually do not work since commit 7da7b84f ("ARM: dts: imx6dl-yapp4: Move phy reset into switch node") as a coincidence of several circumstances. The reset signal is kept asserted by a pull-down resistor on the board unless it is deasserted by GPIO from the SoC. This is to keep the switch dead until it is configured properly by the kernel and user space. Prior to the referenced commit the switch was reset by the FEC driver and the reset GPIO was actively deasserted. The mdio-bus was scanned and the attached switch and its PHYs were found and configured. With the referenced commit the switch is reset by the qca8k driver. Because of another bug in the qca8k driver, functionality of the reset pin depends on its pre-kernel configuration. See commit c44fc98f ("net: dsa: qca8k: fix illegal usage of GPIO") The problem did not appear until we removed support for the switch and configuration of its reset pin from the bootloader. To fix that, properly describe the internal mdio-bus configuration of the qca8334 switch. The PHYs are internal to the switch and sit on its internal mdio-bus.

[ Upstream commit 3baa4c51 ] When the development chip ROM was added, the "direct-mapped" compatible value was already obsolete. In addition, the device node lacked the accompanying "probe-type" property, causing the old physmap_of_core driver to fall back to trying all available probe types.

[ Upstream commit 0feda94c ] On many systems that have an AMD IOMMU the following sequence of warnings is observed during bootup. ``` pci 0000:00:00.2 can't derive routing for PCI INT A pci 0000:00:00.2: PCI INT A: not connected ``` This series of events happens because of the IOMMU initialization sequence order and the lack of _PRT entries for the IOMMU. During initialization the IOMMU driver first enables the PCI device using pci_enable_device(). This will call acpi_pci_irq_enable() which will check if the interrupt is declared in a PCI routing table (_PRT) entry. According to the PCI spec [1] these routing entries are only required under PCI root bridges: The _PRT object is required under all PCI root bridges The IOMMU is directly connected to the root complex, so there is no parent bridge to look for a _PRT entry. The first warning is emitted since no entry could be found in the hierarchy. The second warning is then emitted because the interrupt hasn't yet been configured to any value. The pin was configured in pci_read_irq() but the byte in PCI_INTERRUPT_LINE return 0xff which means "Unknown". After that sequence of events pci_enable_msi() is called and this will allocate an interrupt. That is both of these warnings are totally harmless because the IOMMU uses MSI for interrupts. To avoid even trying to probe for a _PRT entry mark the IOMMU as IRQ managed. This avoids both warnings.

When unregistering a net device, since the needs_free_netdev has been set to true during registration, the netdevice object is also freed, and as a consequence, the corresponding vif object too, since it is attached to it as private netdevice data. The next occurrence of the loop then tries to access freed vif pointer to the list to move forward in the list. Fix this use-after-free thanks to two mechanisms: - navigate in the list with list_for_each_entry_safe, which allows to safely modify the list as we go through each element. For each element, remove it from the list with list_del_rcu - make sure to wait for RCU grace period end after each vif removal to make sure it is safe to free the corresponding vif too (through unregister_netdev) Since we are in a RCU "modifier" path (not a "reader" path), and because such path is expected not to be concurrent to any other modifier (we are using the vif_mutex lock), we do not need to use RCU list API, that's why we can benefit from list_for_each_entry_safe.

[ Upstream commit 178c5466 ] Currently tracing is supposed not to allow for bpf_spin_{lock,unlock}() helper calls. This is to prevent deadlock for the following cases: - there is a prog (prog-A) calling bpf_spin_{lock,unlock}(). - there is a tracing program (prog-B), e.g., fentry, attached to bpf_spin_lock() and/or bpf_spin_unlock(). - prog-B calls bpf_spin_{lock,unlock}(). For such a case, when prog-A calls bpf_spin_{lock,unlock}(), a deadlock will happen. The related source codes are below in kernel/bpf/helpers.c: notrace BPF_CALL_1(bpf_spin_lock, struct bpf_spin_lock *, lock) notrace BPF_CALL_1(bpf_spin_unlock, struct bpf_spin_lock *, lock) notrace is supposed to prevent fentry prog from attaching to bpf_spin_{lock,unlock}(). But actually this is not the case and fentry prog can successfully attached to bpf_spin_lock(). Siddharth Chintamaneni reported the issue in [1]. The following is the macro definition for above BPF_CALL_1: #define BPF_CALL_x(x, name, ...) \ static __always_inline \ u64 ____##name(__BPF_MAP(x, __BPF_DECL_ARGS, __BPF_V, __VA_ARGS__)); \ typedef u64 (*btf_##name)(__BPF_MAP(x, __BPF_DECL_ARGS, __BPF_V, __VA_ARGS__)); \ u64 name(__BPF_REG(x, __BPF_DECL_REGS, __BPF_N, __VA_ARGS__)); \ u64 name(__BPF_REG(x, __BPF_DECL_REGS, __BPF_N, __VA_ARGS__)) \ { \ return ((btf_##name)____##name)(__BPF_MAP(x,__BPF_CAST,__BPF_N,__VA_ARGS__));\ } \ static __always_inline \ u64 ____##name(__BPF_MAP(x, __BPF_DECL_ARGS, __BPF_V, __VA_ARGS__)) #define BPF_CALL_1(name, ...) BPF_CALL_x(1, name, __VA_ARGS__) The notrace attribute is actually applied to the static always_inline function ____bpf_spin_{lock,unlock}(). The actual callback function bpf_spin_{lock,unlock}() is not marked with notrace, hence allowing fentry prog to attach to two helpers, and this may cause the above mentioned deadlock. Siddharth Chintamaneni actually has a reproducer in [2]. To fix the issue, a new macro NOTRACE_BPF_CALL_1 is introduced which will add notrace attribute to the original function instead of the hidden always_inline function and this fixed the problem.

[ Upstream commit c8d8f391 ] EWRD ACPI table contains up to 3 additional sar profiles. According to the BIOS spec, the table contains a n_profile variable indicating how many additional profiles exist in the table. Currently we check that n_profiles is not <= 0. But according to the BIOS spec, 0 is a valid value, and it can't be < 0 anyway because we receive that from ACPI as an unsigned integer.

[ Upstream commit 24355fcb ] The ath9k_wmi_event_tasklet() used in ath9k_htc assumes that all the data structures have been fully initialised by the time it runs. However, because of the order in which things are initialised, this is not guaranteed to be the case, because the device is exposed to the USB subsystem before the ath9k driver initialisation is completed. We already committed a partial fix for this in commit: 8b3046ab ("ath9k_htc: fix NULL pointer dereference at ath9k_htc_tx_get_packet()") However, that commit only aborted the WMI_TXSTATUS_EVENTID command in the event tasklet, pairing it with an "initialisation complete" bit in the TX struct. It seems syzbot managed to trigger the race for one of the other commands as well, so let's just move the existing synchronisation bit to cover the whole tasklet (setting it at the end of ath9k_htc_probe_device() instead of inside ath9k_tx_init()).

[ Upstream commit 50180c7f ] debugfs_create_dir() returns ERR_PTR and never return NULL. As Russell suggested, this patch removes the error checking for debugfs_create_dir(). This is because the DebugFS kernel API is developed in a way that the caller can safely ignore the errors that occur during the creation of DebugFS nodes. The debugfs APIs have a IS_ERR() judge in start_creating() which can handle it gracefully. So these checks are unnecessary.

[ Upstream commit 09795bde ] bcm4331 seems to not function correctly with QoS support. This may be due to issues with currently available firmware or potentially a device specific issue. When queues that are not of the default "best effort" priority are selected, traffic appears to not transmit out of the hardware while no errors are returned. This behavior is present among all the other priority queues: video, voice, and background. While this can be worked around by setting a kernel parameter, the default behavior is problematic for most users and may be difficult to debug. This patch offers a working out-of-box experience for bcm4331 users.
