macsec: Enable devices to advertise whether they update sk_buff md_dst during offloads

2024-05-02T14:29:32Z

commit 475747a19316b08e856c666a20503e73d7ed67ed upstream. Omit rx_use_md_dst comment in upstream commit since macsec_ops is not documented. Cannot know whether a Rx skb missing md_dst is intended for MACsec or not without knowing whether the device is able to update this field during an offload. Assume that an offload to a MACsec device cannot support updating md_dst by default. Capable devices can advertise that they do indicate that an skb is related to a MACsec offloaded packet using the md_dst.

af_unix: Suppress false-positive lockdep splat for spin_lock() in __unix_gc().

2024-05-02T14:29:27Z

[ Upstream commit 1971d13ffa84a551d29a81fdf5b5ec5be166ac83 ] syzbot reported a lockdep splat regarding unix_gc_lock and unix_state_lock(). One is called from recvmsg() for a connected socket, and another is called from GC for TCP_LISTEN socket. So, the splat is false-positive. Let's add a dedicated lock class for the latter to suppress the splat. Note that this change is not necessary for net-next.git as the issue is only applied to the old GC impl.

[ Upstream commit 3584718cf2ec7e79b6814f2596dcf398c5fb2eca ] Jonathan Heathcote reported a regression caused by blamed commit on aarch64 architecture. x86 happens to have irq-safe __this_cpu_add_return() and __this_cpu_sub(), but this is not generic. I think my confusion came from "struct sock" argument, because these helpers are called with a locked socket. But the memory accounting is per-proto (and per-cpu after the blamed commit). We might cleanup these helpers later to directly accept a "struct proto *proto" argument. Switch to this_cpu_add_return() and this_cpu_xchg() operations, and get rid of preempt_disable()/preempt_enable() pairs. Fast path becomes a bit faster as a result :) Many thanks to Jonathan Heathcote for his awesome report and investigations.

net: dsa: introduce preferred_default_local_cpu_port and use on MT7530

2024-04-27T15:07:17Z

commit b79d7c14f48083abb3fb061370c0c64a569edf4c upstream. Since the introduction of the OF bindings, DSA has always had a policy that in case multiple CPU ports are present in the device tree, the numerically smallest one is always chosen. The MT7530 switch family, except the switch on the MT7988 SoC, has 2 CPU ports, 5 and 6, where port 6 is preferable on the MT7531BE switch because it has higher bandwidth. The MT7530 driver developers had 3 options: - to modify DSA when the MT7531 switch support was introduced, such as to prefer the better port - to declare both CPU ports in device trees as CPU ports, and live with the sub-optimal performance resulting from not preferring the better port - to declare just port 6 in the device tree as a CPU port Of course they chose the path of least resistance (3rd option), kicking the can down the road. The hardware description in the device tree is supposed to be stable - developers are not supposed to adopt the strategy of piecemeal hardware description, where the device tree is updated in lockstep with the features that the kernel currently supports. Now, as a result of the fact that they did that, any attempts to modify the device tree and describe both CPU ports as CPU ports would make DSA change its default selection from port 6 to 5, effectively resulting in a performance degradation visible to users with the MT7531BE switch as can be seen below.

As such, this change proposes that we retroactively modify stable kernels (which don't support the modification of the CPU port assignments, so as to let user space fix the problem and restore the throughput) to keep the mt7530 driver preferring port 6 even with device trees where the hardware is more fully described.

bootconfig: use memblock_free_late to free xbc memory to buddy

2024-04-27T15:07:17Z

commit 89f9a1e876b5a7ad884918c03a46831af202c8a0 upstream. On the time to free xbc memory in xbc_exit(), memblock may has handed over memory to buddy allocator. So it doesn't make sense to free memory back to memblock. memblock_free() called by xbc_exit() even causes UAF bugs on architectures with CONFIG_ARCH_KEEP_MEMBLOCK disabled like x86. Following KASAN logs shows this case. This patch fixes the xbc memory free problem by calling memblock_free() in early xbc init error rewind path and calling memblock_free_late() in xbc exit path to free memory to buddy allocator.

usb: new quirk to reduce the SET_ADDRESS request timeout

2024-04-27T15:07:12Z

[ Upstream commit 5a1ccf0c72cf917ff3ccc131d1bb8d19338ffe52 ] This patch introduces a new USB quirk, USB_QUIRK_SHORT_SET_ADDRESS_REQ_TIMEOUT, which modifies the timeout value for the SET_ADDRESS request. The standard timeout for USB request/command is 5000 ms, as recommended in the USB 3.2 specification (section 9.2.6.1). However, certain scenarios, such as connecting devices through an APTIV hub, can lead to timeout errors when the device enumerates as full speed initially and later switches to high speed during chirp negotiation. In such cases, USB analyzer logs reveal that the bus suspends for 5 seconds due to incorrect chirp parsing and resumes only after two consecutive timeout errors trigger a hub driver reset.

The newly introduced quirks provide the flexibility to align with a 3-second time limit, as required in specific contexts like automotive applications. By reducing the SET_ADDRESS request timeout to 500 ms, the system can respond more swiftly to errors, initiate rapid recovery, and ensure efficient device enumeration. This change is vital for scenarios where rapid smartphone enumeration and screen projection are essential. To use the quirk, please write "vendor_id:product_id:p" to /sys/bus/usb/drivers/hub/module/parameter/quirks For example, echo "0x2c48:0x0132:p" > /sys/bus/usb/drivers/hub/module/parameters/quirks" Signed-off-by: Hardik Gajjar Reviewed-by: Alan Stern Link: https://lore.kernel.org/r/20231027152029.104363-2-hgajjar@de.adit-jv.com Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin

usb: xhci: Add timeout argument in address_device USB HCD callback

2024-04-27T15:07:11Z

[ Upstream commit a769154c7cac037914ba375ae88aae55b2c853e0 ] - The HCD address_device callback now accepts a user-defined timeout value in milliseconds, providing better control over command execution times. - The default timeout value for the address_device command has been set to 5000 ms, aligning with the USB 3.2 specification. However, this timeout can be adjusted as needed. - The xhci_setup_device function has been updated to accept the timeout value, allowing it to specify the maximum wait time for the command operation to complete. - The hub driver has also been updated to accommodate the newly added timeout parameter during the SET_ADDRESS request.
