2021-11-17NFSv42: Fix pagecache invalidation after COPY/CLONEBenjamin Coddington
The mechanism in use to allow the client to see the results of COPY/CLONE is to drop those pages from the pagecache. This forces the client to read those pages once more from the server. However, truncate_pagecache_range() zeros out partial pages instead of dropping them. Let us instead use invalidate_inode_pages2_range() with full-page offsets to ensure the client properly sees the results of COPY/CLONE operations.

2021-11-17i40e: Fix ping is lost after configuring ADq on VFEryk Rybak
Properly reconfigure VF VSIs after VF request ADQ. Created new function to update queue mapping and queue pairs per TC with AQ update VSI. This sets proper RSS size on NIC. VFs num_queue_pairs should not be changed during setup of queue maps. Previously, VF main VSI in ADQ had configured too many queues and had wrong RSS size, which lead to packets not being consumed and drops in connectivity.

2021-11-17i40e: Fix changing previously set num_queue_pairs for PFsEryk Rybak
Currently, the i40e_vsi_setup_queue_map is basing the count of queues in TCs on a VSI's alloc_queue_pairs member which is not changed throughout any user's action (for example via ethtool's set_channels callback). This implies that vsi->tc_config.tc_info[n].qcount value that is given to the kernel via netdev_set_tc_queue() that notifies about the count of queues per particular traffic class is constant even if user has changed the total count of queues. This in turn caused the kernel warning after setting the queue count to the lower value than the initial one: $ ethtool -l ens801f0 Channel parameters for ens801f0: Pre-set maximums: RX: 0 TX: 0 Other: 1 Combined: 64 Current hardware settings: RX: 0 TX: 0 Other: 1 Combined: 64 $ ethtool -L ens801f0 combined 40 [dmesg] Number of in use tx queues changed invalidating tc mappings. Priority traffic classification disabled! Reason was that vsi->alloc_queue_pairs stayed at 64 value which was used to set the qcount on TC0 (by default only TC0 exists so all of the existing queues are assigned to TC0). we update the offset/qcount via netdev_set_tc_queue() back to the old value but then the netif_set_real_num_tx_queues() is using the vsi->num_queue_pairs as a value which got set to 40. Fix it by using vsi->req_queue_pairs as a queue count that will be distributed across TCs. Do it only for non-zero values, which implies that user actually requested the new count of queues. For VSIs other than main, stay with the vsi->alloc_queue_pairs as we only allow manipulating the queue count on main VSI.

2021-11-17net: virtio_net_hdr_to_skb: count transport header in UFOJonathan Davies
virtio_net_hdr_to_skb does not set the skb's gso_size and gso_type correctly for UFO packets received via virtio-net that are a little over the GSO size. This can lead to problems elsewhere in the networking stack, e.g. ovs_vport_send dropping over-sized packets if gso_size is not set. This is due to the comparison if (skb->len - p_off > gso_size) not properly accounting for the transport layer header. p_off includes the size of the transport layer header (thlen), so skb->len - p_off is the size of the TCP/UDP payload. gso_size is read from the virtio-net header. For UFO, fragmentation happens at the IP level so does not need to include the UDP header. Hence the calculation could be comparing a TCP/UDP payload length with an IP payload length, causing legitimate virtio-net packets to have lack gso_type/gso_size information. Example: a UDP packet with payload size 1473 has IP payload size 1481. If the guest used UFO, it is not fragmented and the virtio-net header's flags indicate that it is a GSO frame (VIRTIO_NET_HDR_GSO_UDP), with gso_size = 1480 for an MTU of 1500. skb->len will be 1515 and p_off will be 42, so skb->len - p_off = 1473. Hence the comparison fails, and shinfo->gso_size and gso_type are not set as they should be. Instead, add the UDP header length before comparing to gso_size when using UFO. In this way, it is the size of the IP payload that is compared to gso_size.

2021-11-17usb: hub: Fix usb enumeration issue due to address0 raceMathias Nyman
xHC hardware can only have one slot in default state with address 0 waiting for a unique address at a time, otherwise "undefined behavior may occur" according to xhci spec 5.4.3.4 The address0_mutex exists to prevent this across both xhci roothubs. If hub_port_init() fails, it may unlock the mutex and exit with a xhci slot in default state. If the other xhci roothub calls hub_port_init() at this point we end up with two slots in default state. Make sure the address0_mutex protects the slot default state across hub_port_init() retries, until slot is addressed or disabled. Note, one known minor case is not fixed by this patch. If device needs to be reset during resume, but fails all hub_port_init() retries in usb_reset_and_verify_device(), then it's possible the slot is still left in default state when address0_mutex is unlocked.

2021-11-17usb: typec: fusb302: Fix masking of comparator and bc_lvl interruptsOndrej Jirman
The code that enables either BC_LVL or COMP_CHNG interrupt in tcpm_set_cc wrongly assumes that the interrupt is unmasked by writing 1 to the apropriate bit in the mask register. In fact, interrupts are enabled when the mask is 0, so the tcpm_set_cc enables interrupt for COMP_CHNG when it expects BC_LVL interrupt to be enabled. This causes inability of the driver to recognize cable unplug events in host mode (unplug is recognized only via a COMP_CHNG interrupt). In device mode this bug was masked by simultaneous triggering of the VBUS change interrupt, because of loss of VBUS when the port peer is providing power.

2021-11-17usb: dwc2: hcd_queue: Fix use of floating point literalNathan Chancellor
A new commit in LLVM causes an error on the use of 'long double' when '-mno-x87' is used, which the kernel does through an alias, '-mno-80387' (see the LLVM commit below for more details around why it does this). drivers/usb/dwc2/hcd_queue.c:1744:25: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it delay = ktime_set(0, DWC2_RETRY_WAIT_DELAY); ^ drivers/usb/dwc2/hcd_queue.c:62:34: note: expanded from macro 'DWC2_RETRY_WAIT_DELAY' #define DWC2_RETRY_WAIT_DELAY (1 * 1E6L) ^ 1 error generated. This happens due to the use of a 'long double' literal. The 'E6' part of '1E6L' causes the literal to be a 'double' then the 'L' suffix promotes it to 'long double'. There is no visible reason for a floating point value in this driver, as the value is only used as a parameter to a function that expects an integer type. Use NSEC_PER_MSEC, which is the same integer value as '1E6L', to avoid changing functionality but fix the error.

2021-11-17usb: dwc3: gadget: Check for L1/L2/U3 for Start TransferThinh Nguyen
The programming guide noted that the driver needs to verify if the link state is in U0 before executing the Start Transfer command. If it's not in U0, the driver needs to perform remote wakeup. This is not accurate. If the link state is in U1/U2, then the controller will not respond to link recovery request from DCTL.ULSTCHNGREQ. The Start Transfer command will trigger a link recovery if it is in U1/U2. A clarification will be added to the programming guide for all controller versions. The current implementation shouldn't cause any functional issue. It may occasionally report an invalid time out warning from failed link recovery request. The driver will still go ahead with the Start Transfer command if the remote wakeup fails. The new change only initiates remote wakeup where it is needed, which is when the link state is in L1/L2/U3.
