If ports are not turned off in shutdown then runtime suspended self-powered USB devices may survive in U3 link state over S5. During subsequent boot, if firmware sends an IPC command to program the port in DISCONNECT state, it will time out, causing significant delay in the boot time. Turning off roothub port power is also recommended in xhci specification 4.19.4 "Port Power" in the additional note. Cc: stable@vger.kernel.org Signed-off-by:

irq is disabled in xhci_quiesce(called by xhci_halt, with bit:2 cleared in USBCMD register), but xhci_run(called by usb_add_hcd) re-enable it. It's possible that you will receive thousands of interrupt requests after initialization for 2.0 roothub. And you will get a lot of warning like, "xHCI dying, ignoring interrupt. Shouldn't IRQs be disabled?". This amount of interrupt requests will cause the entire system to freeze. This problem was first found on a device with ASM2142 host controller on it.

User needs to write AT commands to this device node to query status, set APN, set PIN code, and enable/disable the data connection to 5G network. - ethX: this is the data path provided as a RNDIS devices.

Add support for further HXN (G) type devices (GT variant, GL variant, GS variant and GR) and document the bcdDevice mapping. Note that the TA and TB types use the same bcdDevice as some GT and GE variants, respectively, but that the HX status request can be used to determine which is which. Also note that we currently do not distinguish between the various HXN (G) types in the driver but that this may change eventually (e.g. when adding GPIO support). Reported-by:

In a report for a separate bug (which has already been fixed by commit 5f0b5f4d "usb: gadget: fix race when gadget driver register via ioctl") in the raw-gadget driver, the syzbot console log included error messages caused by attempted registration of a new driver with the same name as an existing driver: > kobject_add_internal failed for raw-gadget with -EEXIST, don't try to register things with the same name in the same directory. > UDC core: USB Raw Gadget: driver registration failed: -17 > misc raw-gadget: fail, usb_gadget_register_driver returned -17 These errors arise because raw_gadget.c registers a separate UDC driver for each of the UDC instances it creates, but these drivers all have the same name: "raw-gadget". Until recently this wasn't a problem, but when the "gadget" bus was added and UDC drivers were registered on this bus, it became possible for name conflicts to cause the registrations to fail. The reason is simply that the bus code in the driver core uses the driver name as a sysfs directory name (e.g., /sys/bus/gadget/drivers/raw-gadget/), and you can't create two directories with the same pathname. To fix this problem, the driver names used by raw-gadget are made distinct by appending a unique ID number: "raw-gadget.N", with a different value of N for each driver instance. And to avoid the proliferation of error handling code in the raw_ioctl_init() routine, the error return paths are refactored into the common pattern (goto statements leading to cleanup code at the end of the routine).

We capture a NULL pointer issue when resizing a corrupt ext4 image which is freshly clear resize_inode feature (not run e2fsck). It could be simply reproduced by following steps. The problem is because of the resize_inode feature was cleared, and it will convert the filesystem to meta_bg mode in ext4_resize_fs(), but the es->s_reserved_gdt_blocks was not reduced to zero, so could we mistakenly call reserve_backup_gdb() and passing an uninitialized resize_inode to it when adding new group descriptors. mkfs.ext4 /dev/sda 3G tune2fs -O ^resize_inode /dev/sda #forget to run requested e2fsck mount /dev/sda /mnt resize2fs /dev/sda 8G ======== BUG: kernel NULL pointer dereference, address: 0000000000000028 CPU: 19 PID: 3243 Comm: resize2fs Not tainted 5.18.0-rc7-00001-gfde086c5ebfd #748 ...

Since ext4 was converted to the new mount API, the test_dummy_encryption mount option isn't being handled entirely correctly, because the needed fscrypt_set_test_dummy_encryption() helper function combines parsing/checking/applying into one function. That doesn't work well with the new mount API, which split these into separate steps. This was sort of okay anyway, due to the parsing logic that was copied from fscrypt_set_test_dummy_encryption() into ext4_parse_param(), combined with an additional check in ext4_check_test_dummy_encryption(). However, these overlooked the case of changing the value of test_dummy_encryption on remount, which isn't allowed but ext4 wasn't detecting until ext4_apply_options() when it's too late to fail. Another bug is that if test_dummy_encryption was specified multiple times with an argument, memory was leaked. Fix this up properly by using the new helper functions that allow splitting up the parse/check/apply steps for test_dummy_encryption.

load_unaligned_zeropad() can lead to unwanted loads across page boundaries. The unwanted loads are typically harmless. But, they might be made to totally unrelated or even unmapped memory. load_unaligned_zeropad() relies on exception fixup (#PF, #GP and now #VE) to recover from these unwanted loads. In TDX guests, the second page can be shared page and a VMM may configure it to trigger #VE. The kernel assumes that #VE on a shared page is an MMIO access and tries to decode instruction to handle it. In case of load_unaligned_zeropad() it may result in confusion as it is not MMIO access. Fix it by detecting split page MMIO accesses and failing them. load_unaligned_zeropad() will recover using exception fixups. The issue was discovered by analysis and reproduced artificially. It was not triggered during testing. [ dhansen: fix up changelogs and comments for grammar and clarity, plus incorporate Kirill's off-by-one fix] Signed-off-by:

This reverts commit 4c5e242d. Prior to 4c5e242d ("x86/PCI: Clip only host bridge windows for E820 regions"), E820 regions did not affect PCI host bridge windows. We only looked at E820 regions and avoided them when allocating new MMIO space. If firmware PCI bridge window and BAR assignments used E820 regions, we left them alone. After 4c5e242d, we removed E820 regions from the PCI host bridge windows before looking at BARs, so firmware assignments in E820 regions looked like errors, and we moved things around to fit in the space left (if any) after removing the E820 regions. This unnecessary BAR reassignment broke several machines. Guilherme reported that Steam Deck fails to boot after 4c5e242d. We clipped the window that contained most 32-bit BARs: BIOS-e820: [mem 0x00000000a0000000-0x00000000a00fffff] reserved acpi PNP0A08:00: clipped [mem 0x80000000-0xf7ffffff window] to [mem 0xa0100000-0xf7ffffff window] for e820 entry [mem 0xa0000000-0xa00fffff] which forced us to reassign all those BARs, for example, this NVMe BAR: pci 0000:00:01.2: PCI bridge to [bus 01] pci 0000:00:01.2: bridge window [mem 0x80600000-0x806fffff] pci 0000:01:00.0: BAR 0: [mem 0x80600000-0x80603fff 64bit] pci 0000:00:01.2: can't claim window [mem 0x80600000-0x806fffff]: no compatible bridge window pci 0000:01:00.0: can't claim BAR 0 [mem 0x80600000-0x80603fff 64bit]: no compatible bridge window pci 0000:00:01.2: bridge window: assigned [mem 0xa0100000-0xa01fffff] pci 0000:01:00.0: BAR 0: assigned [mem 0xa0100000-0xa0103fff 64bit] All the reassignments were successful, so the devices should have been functional at the new addresses, but some were not. Andy reported a similar failure on an Intel MID platform. Benjamin reported a similar failure on a VMWare Fusion VM. Note: this is not a clean revert; this revert keeps the later change to make the clipping dependent on a new pci_use_e820 bool, moving the checking of this bool to arch_remove_reservations().
