2023-10-02ovl: make use of ->layers safe in rcu pathwalkAmir Goldstein
ovl_permission() accesses ->layers[...].mnt; we can't have ->layers freed without an RCU delay on fs shutdown. Fortunately, kern_unmount_array() that is used to drop those mounts does include an RCU delay, so freeing is delayed; unfortunately, the array passed to kern_unmount_array() is formed by mangling ->layers contents and that happens without any delays. The ->layers[...].name string entries are used to store the strings to display in "lowerdir=..." by ovl_show_options(). Those entries are not accessed in RCU walk. Move the name strings into a separate array ofs->config.lowerdirs and reuse the ofs->config.lowerdirs array as the temporary mount array to pass to kern_unmount_array().

2023-10-02xhci: Preserve RsvdP bits in ERSTBA register correctlyLukas Wunner
xhci_add_interrupter() erroneously preserves only the lowest 4 bits when writing the ERSTBA register, not the lowest 6 bits. Fix it. Migrate the ERST_BASE_RSVDP macro to the modern GENMASK_ULL() syntax to avoid a u64 cast. This was previously fixed by commit 8c1cbec9db1a ("xhci: fix event ring segment table related masks and variables in header"), but immediately undone by commit b17a57f89f69 ("xhci: Refactor interrupter code for initial multi interrupter support.").

2023-10-02xhci: Clear EHB bit only at end of interrupt handlerLukas Wunner
The Event Handler Busy bit shall be cleared by software when the Event Ring is empty. The xHC is thereby informed that it may raise another interrupt once it has enqueued new events (sec 4.17.2). However since commit dc0ffbea5729 ("usb: host: xhci: update event ring dequeue pointer on purpose"), the EHB bit is already cleared after half a segment has been processed. As a result, spurious interrupts may occur: - xhci_irq() processes half a segment, clears EHB, continues processing remaining events. - xHC enqueues new events. Because EHB has been cleared, xHC sets Interrupt Pending bit. Interrupt moderation countdown begins. - Meanwhile xhci_irq() continues processing events. Interrupt moderation countdown reaches zero, so an MSI interrupt is signaled. - xhci_irq() empties the Event Ring, clears EHB again and is done. - Because an MSI interrupt has been signaled, xhci_irq() is run again. It discovers there's nothing to do and returns IRQ_NONE. Avoid by clearing the EHB bit only at the end of xhci_irq().

2023-10-02xhci: track port suspend state correctly in unsuccessful resume casesMathias Nyman
xhci-hub.c tracks suspended ports in a suspended_port bitfield. This is checked when responding to a Get_Status(PORT) request to see if a port in running U0 state was recently resumed, and adds the required USB_PORT_STAT_C_SUSPEND change bit in those cases. The suspended_port bit was left uncleared if a device is disconnected during suspend. The bit remained set even when a new device was connected and enumerated. The set bit resulted in a incorrect Get_Status(PORT) response with a bogus USB_PORT_STAT_C_SUSPEND change bit set once the new device reached U0 link state. USB_PORT_STAT_C_SUSPEND change bit is only used for USB2 ports, but xhci-hub keeps track of both USB2 and USB3 suspended ports.

2023-10-02usb: xhci: xhci-ring: Use sysdev for mapping bounce bufferWesley Cheng
As mentioned in: commit 474ed23a6257 ("xhci: align the last trb before link if it is easily splittable.") A bounce buffer is utilized for ensuring that transfers that span across ring segments are aligned to the EP's max packet size. However, the device that is used to map the DMA buffer to is currently using the XHCI HCD, which does not carry any DMA operations in certain configrations. Migration to using the sysdev entry was introduced for DWC3 based implementations where the IOMMU operations are present. Replace the reference to the controller device to sysdev instead. This allows the bounce buffer to be properly mapped to any implementations that have an IOMMU involved. cc: stable@vger.kernel.org Fixes: 4c39d4b949d3 ("usb: xhci: use bus->sysdev for DMA configuration") Signed-off-by: Wesley Cheng <quic_wcheng@quicinc.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20230915143108.1532163-2-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2023-10-02x86/sev: Use the GHCB protocol when available for SNP CPUID requestsTom Lendacky
SNP retrieves the majority of CPUID information from the SNP CPUID page. But there are times when that information needs to be supplemented by the hypervisor, for example, obtaining the initial APIC ID of the vCPU from leaf 1. The current implementation uses the MSR protocol to retrieve the data from the hypervisor, even when a GHCB exists. The problem arises when an NMI arrives on return from the VMGEXIT. The NMI will be immediately serviced and may generate a #VC requiring communication with the hypervisor. Since a GHCB exists in this case, it will be used. As part of using the GHCB, the #VC handler will write the GHCB physical address into the GHCB MSR and the #VC will be handled. When the NMI completes, processing resumes at the site of the VMGEXIT which is expecting to read the GHCB MSR and find a CPUID MSR protocol response. Since the NMI handling overwrote the GHCB MSR response, the guest will see an invalid reply from the hypervisor and self-terminate. Fix this problem by using the GHCB when it is available. Any NMI received is properly handled because the GHCB contents are copied into a backup page and restored on NMI exit, thus preserving the active GHCB request or result.

2023-10-02usb: dwc3: Soft reset phy on probe for hostThinh Nguyen
When there's phy initialization, we need to initiate a soft-reset sequence. That's done through USBCMD.HCRST in the xHCI driver and its initialization, However, the dwc3 driver may modify core configs before the soft-reset. This may result in some connection instability. So, ensure the phy is ready before the controller updates the GCTL.PRTCAPDIR or other settings by issuing phy soft-reset. Note that some host-mode configurations may not expose device registers to initiate the controller soft-reset (via DCTL.CoreSftRst). So we reset through GUSB3PIPECTL and GUSB2PHYCFG instead.

In the pathological case of building sky2 with 16k PAGE_SIZE, the frag_addr[] array would never be used, so the original code was correct that size should be 0. But the compiler now gets upset with 0 size arrays in places where it hasn't eliminated the code that might access such an array (it can't figure out that in this case an rx skb with fragments would never be created).

2023-10-02net: dsa: mv88e6xxx: Avoid EEPROM timeout when EEPROM is absentFabio Estevam
Since commit 23d775f12dcd ("net: dsa: mv88e6xxx: Wait for EEPROM done before HW reset") the following error is seen on a imx8mn board with a 88E6320 switch: mv88e6085 30be0000.ethernet-1:00: Timeout waiting for EEPROM done This board does not have an EEPROM attached to the switch though. This problem is well explained by Andrew Lunn: "If there is an EEPROM, and the EEPROM contains a lot of data, it could be that when we perform a hardware reset towards the end of probe, it interrupts an I2C bus transaction, leaving the I2C bus in a bad state, and future reads of the EEPROM do not work. The work around for this was to poll the EEInt status and wait for it to go true before performing the hardware reset. However, we have discovered that for some boards which do not have an EEPROM, EEInt never indicates complete. As a result, mv88e6xxx_g1_wait_eeprom_done() spins for a second and then prints a warning. We probably need a different solution than calling mv88e6xxx_g1_wait_eeprom_done(). The datasheet for 6352 documents the EEPROM Command register: bit 15 is: EEPROM Unit Busy. This bit must be set to a one to start an EEPROM operation (see EEOp below). Only one EEPROM operation can be executing at one time so this bit must be zero before setting it to a one. When the requested EEPROM operation completes this bit will automatically be cleared to a zero. The transition of this bit from a one to a zero can be used to generate an interrupt (the EEInt in Global 1, offset 0x00). and more interesting is bit 11: Register Loader Running. This bit is set to one whenever the register loader is busy executing instructions contained in the EEPROM." Change to using mv88e6xxx_g2_eeprom_wait() to fix the timeout error when the EEPROM chip is not present.

2023-10-01net: prevent address rewrite in kernel_bind()Jordan Rife
Similar to the change in commit 0bdf399342c5("net: Avoid address overwrite in kernel_connect"), BPF hooks run on bind may rewrite the address passed to kernel_bind(). This change 1) Makes a copy of the bind address in kernel_bind() to insulate callers. 2) Replaces direct calls to sock->ops->bind() in net with kernel_bind() Link: https://lore.kernel.org/netdev/20230912013332.2048422-1-jrife@google.com/ Fixes: 4fbac77d2d09 ("bpf: Hooks for sys_bind") Cc: stable@vger.kernel.org Reviewed-by: Willem de Bruijn <willemb@google.com> Signed-off-by: Jordan Rife <jrife@google.com> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: David S.

2023-10-01net: prevent rewrite of msg_name in sock_sendmsg()Jordan Rife
Callers of sock_sendmsg(), and similarly kernel_sendmsg(), in kernel space may observe their value of msg_name change in cases where BPF sendmsg hooks rewrite the send address. This has been confirmed to break NFS mounts running in UDP mode and has the potential to break other systems. This patch: 1) Creates a new function called __sock_sendmsg() with same logic as the old sock_sendmsg() function. 2) Replaces calls to sock_sendmsg() made by __sys_sendto() and __sys_sendmsg() with __sock_sendmsg() to avoid an unnecessary copy, as these system calls are already protected. 3) Modifies sock_sendmsg() so that it makes a copy of msg_name if present before passing it down the stack to insulate callers from changes to the send address.
