2021-11-01vdpa: Introduce query of device config layoutParav Pandit3-0/+184
Introduce a command to query a device config layout.

2021-11-01vdpa: Introduce and use vdpa device get, set config helpersParav Pandit4-19/+42
Subsequent patches enable get and set configuration either via management device or via vdpa device' config ops. This requires synchronization between multiple callers to get and set config callbacks. Features setting also influence the layout of the configuration fields endianness. To avoid exposing synchronization primitives to callers, introduce helper for setting the configuration and use it.

2021-11-01virtio_ring: validate used buffer lengthJason Wang2-0/+62
This patch validate the used buffer length provided by the device before trying to use it. This is done by record the in buffer length in a new field in desc_state structure during virtqueue_add(), then we can fail the virtqueue_get_buf() when we find the device is trying to give us a used buffer length which is greater than the in buffer length. Since some drivers have already done the validation by themselves, this patch tries to makes the core validation optional. For the driver that doesn't want the validation, it can set the suppress_used_validation to be true (which could be overridden by force_used_validation module parameter). To be more efficient, a dedicate array is used for storing the validate used length, this helps to eliminate the cache stress if validation is done by the driver.

2021-11-01virtio_blk: correct types for status handlingMichael S. Tsirkin1-6/+8
virtblk_setup_cmd returns blk_status_t in an int, callers then assign it back to a blk_status_t variable. blk_status_t is either u32 or (more typically) u8 so it works, but is inelegant and causes sparse warnings.

The default value is 0 meaning "no limit". However if 0 is specified on the command line it is instead silently converted to 1. Further, the value is already validated at point of use, there's no point in duplicating code validating the value when it is set.

This patch tries to make sure the virtio interrupt handler for INTX won't be called after a reset and before virtio_device_ready(). We can't use IRQF_NO_AUTOEN since we're using shared interrupt (IRQF_SHARED).

2021-11-01virtio_pci: harden MSI-X interruptsJason Wang4-12/+32
We used to synchronize pending MSI-X irq handlers via synchronize_irq(), this may not work for the untrusted device which may keep sending interrupts after reset which may lead unexpected results. Similarly, we should not enable MSI-X interrupt until the device is ready. So this patch fixes those two issues by: 1) switching to use disable_irq() to prevent the virtio interrupt handlers to be called after the device is reset. 2) using IRQF_NO_AUTOEN and enable the MSI-X irq during .ready() This can make sure the virtio interrupt handler won't be called before virtio_device_ready() and after reset.

When virtio-rng device was dropped by the hwrng core we were forced to wait the buffer to come back from the device to not have remaining ongoing operation that could spoil the buffer. But now, as the buffer is internal to the virtio-rng we can release the waiting loop immediately, the buffer will be retrieve and use when the virtio-rng driver will be selected again. This avoids to hang on an rng_current write command if the virtio-rng device is blocked by a lack of entropy. This allows to select another entropy source if the current one is empty.

2021-11-01hwrng: virtio - add an internal bufferLaurent Vivier1-10/+33
hwrng core uses two buffers that can be mixed in the virtio-rng queue. If the buffer is provided with wait=0 it is enqueued in the virtio-rng queue but unused by the caller. On the next call, core provides another buffer but the first one is filled instead and the new one queued. And the caller reads the data from the new one that is not updated, and the data in the first one are lost. To avoid this mix, virtio-rng needs to use its own unique internal buffer at a cost of a data copy to the caller buffer.

2021-11-01virtio-blk: avoid preallocating big SGL for dataMax Gurtovoy2-56/+101
No need to pre-allocate a big buffer for the IO SGL anymore. If a device has lots of deep queues, preallocation for the sg list can consume substantial amounts of memory. For HW virtio-blk device, nr_hw_queues can be 64 or 128 and each queue's depth might be 128. This means the resulting preallocation for the data SGLs is big. Switch to runtime allocation for SGL for lists longer than 2 entries. This is the approach used by NVMe drivers so it should be reasonable for virtio block as well. Runtime SGL allocation has always been the case for the legacy I/O path so this is nothing new. The preallocated small SGL depends on SG_CHAIN so if the ARCH doesn't support SG_CHAIN, use only runtime allocation for the SGL. Re-organize the setup of the IO request to fit the new sg chain mechanism.

2021-11-01netfilter: conntrack: set on IPS_ASSURED if flows enters internal stream statePablo Neira Ayuso1-2/+5
The internal stream state sets the timeout to 120 seconds 2 seconds after the creation of the flow, attach this internal stream state to the IPS_ASSURED flag for consistent event reporting.

Before this patch, IPS_ASSURED is set on regardless the internal stream state, attach this internal stream state to IPS_ASSURED. packet #1 (original direction) enters NEW state packet #2 (reply direction) enters ESTABLISHED state, sets on IPS_SEEN_REPLY paclet #3 (any direction) sets on IPS_ASSURED (if 2 seconds since the creation has passed by).

2021-11-01ALSA: usb-audio: Line6 HX-Stomp XL USB_ID for 48k-fixed quirkJason Ormes1-0/+1
Adding the Line6 HX-Stomp XL USB_ID as it needs this fixed frequency quirk as well. The device is basically just the HX-Stomp with some more buttons on the face. I've done some recording with it after adding it, and it seems to function properly with this fix. The Midi features appear to be working as well.
