2022-11-25octeontx2-pf: Fix pfc_alloc_status array overflowSuman Ghosh1-1/+1
This patch addresses pfc_alloc_status array overflow occurring for send queue index value greater than PFC priority. Queue index can be greater than supported PFC priority for multiple scenarios (e.g. QoS, during non zero SMQ allocation for a PF/VF). In those scenarios the API should return default tx scheduler '0'. This is causing mbox errors as otx2_get_smq_idx returing invalid smq value.

2022-11-25net: stmmac: Set MAC's flow control register to reflect current settingsGoh, Wei Sheng2-2/+12
Currently, pause frame register GMAC_RX_FLOW_CTRL_RFE is not updated correctly when 'ethtool -A <IFACE> autoneg off rx off tx off' command is issued. This fix ensures the flow control change is reflected directly in the GMAC_RX_FLOW_CTRL_RFE register.

2022-11-25aquantia: Do not purge addresses when setting the number of ringsIzabela Bakollari3-4/+7
IPV6 addresses are purged when setting the number of rx/tx rings using ethtool -G. The function aq_set_ringparam calls dev_close, which removes the addresses. As a solution, call an internal function (aq_ndev_close).

2022-11-25qed: avoid defines prefixed with CONFIGLukas Bulwahn1-12/+12
Defines prefixed with "CONFIG" should be limited to proper Kconfig options, that are introduced in a Kconfig file. Here, constants for bitmap indices of some configs are defined and these defines begin with the config's name, and are suffixed with BITMAP_IDX. To avoid defines prefixed with "CONFIG", name these constants BITMAP_IDX_FOR_CONFIG_XYZ instead of CONFIG_XYZ_BITMAP_IDX. No functional change.

2022-11-25qlcnic: fix sleep-in-atomic-context bugs caused by msleepDuoming Zhou1-2/+2
The watchdog timer is used to monitor whether the process of transmitting data is timeout. If we use qlcnic driver, the dev_watchdog() that is the timer handler of watchdog timer will call qlcnic_tx_timeout() to process the timeout. But the qlcnic_tx_timeout() calls msleep(), as a result, the sleep-in-atomic-context bugs will happen. The processes are shown below: (atomic context) dev_watchdog qlcnic_tx_timeout qlcnic_83xx_idc_request_reset qlcnic_83xx_lock_driver msleep --------------------------- (atomic context) dev_watchdog qlcnic_tx_timeout qlcnic_83xx_idc_request_reset qlcnic_83xx_lock_driver qlcnic_83xx_recover_driver_lock msleep Fix by changing msleep() to mdelay(), the mdelay() is busy-waiting and the bugs could be mitigated.

2022-11-24can: mcba_usb: Fix termination command argumentYasushi SHOJI1-3/+7
Microchip USB Analyzer can activate the internal termination resistors by setting the "termination" option ON, or OFF to to deactivate them. As I've observed, both with my oscilloscope and captured USB packets below, you must send "0" to turn it ON, and "1" to turn it OFF. From the schematics in the user's guide, I can confirm that you must drive the CAN_RES signal LOW "0" to activate the resistors. Reverse the argument value of usb_msg.termination to fix this.

In vp_modern_find_vqs(), all queues will be selected and activated, but once queues are enabled there is no way to go back except reset. Fix it by reset virtio device on error handling path. This makes error handling follow the same order as normal device cleanup in virtnet_remove() which does: unregister, destroy failover, then reset. And that flow is better tested than error handling so we can be reasonably sure it works well.

In vf lag, the checking of eswitch mode none is replaced by checking if sriov is enabled. But when driver enables sriov, it triggers the bond workqueue task first and then setting sriov number in pci_enable_sriov(). So the check fails. Fix it by checking if sriov is enabled using eswitch internal counter that is set before triggering the bond workqueue task.

2022-11-23net: enetc: preserve TX ring priority across reconfigurationVladimir Oltean3-11/+19
In the blamed commit, a rudimentary reallocation procedure for RX buffer descriptors was implemented, for the situation when their format changes between normal (no PTP) and extended (PTP). enetc_hwtstamp_set() calls enetc_close() and enetc_open() in a sequence, and this sequence loses information which was previously configured in the TX BDR Mode Register, specifically via the enetc_set_bdr_prio() call. The TX ring priority is configured by tc-mqprio and tc-taprio, and affects important things for TSN such as the TX time of packets. The issue manifests itself most visibly by the fact that isochron --txtime reports premature packet transmissions when PTP is first enabled on an enetc interface. Save the TX ring priority in a new field in struct enetc_bdr (occupies a 2 byte hole on arm64) in order to make this survive a ring reconfiguration.

2022-11-23nfc: st-nci: fix incorrect sizing calculations in EVT_TRANSACTIONMartin Faltesek1-15/+36
The transaction buffer is allocated by using the size of the packet buf, and subtracting two which seems intended to remove the two tags which are not present in the target structure. This calculation leads to under counting memory because of differences between the packet contents and the target structure. The aid_len field is a u8 in the packet, but a u32 in the structure, resulting in at least 3 bytes always being under counted. Further, the aid data is a variable length field in the packet, but fixed in the structure, so if this field is less than the max, the difference is added to the under counting. To fix, perform validation checks progressively to safely reach the next field, to determine the size of both buffers and verify both tags. Once all validation checks pass, allocate the buffer and copy the data. This eliminates freeing memory on the error path, as validation checks are moved ahead of memory allocation.

Either ublk_can_use_task_work() is true or not, io commands are forwarded to ublk server in reverse order, since llist_add() is always to add one element to the head of the list. Even though block layer doesn't guarantee request dispatch order, requests should be sent to hardware in the sequence order generated from io scheduler, which usually considers the request's LBA, and order is often important for HDD. So forward io commands in the sequence made from io scheduler by aligning task work with current io_uring command's batch handling, and it has been observed that both can get similar performance data if IORING_SETUP_COOP_TASKRUN is set from ublk server.
