2022-05-22ath10k: do not enforce interrupt trigger typeKrzysztof Kozlowski1-3/+2
Interrupt line can be configured on different hardware in different way, even inverted. Therefore driver should not enforce specific trigger type - edge rising - but instead rely on Devicetree to configure it. All Qualcomm DTSI with WCN3990 define the interrupt type as level high, so the mismatch between DTSI and driver causes rebind issues: $ echo 18800000.wifi > /sys/bus/platform/drivers/ath10k_snoc/unbind $ echo 18800000.wifi > /sys/bus/platform/drivers/ath10k_snoc/bind [ 44.763114] irq: type mismatch, failed to map hwirq-446 for interrupt-controller@17a00000!

2022-05-20wwan: iosm: use a flexible array rather than allocate short objectsJakub Kicinski1-4/+1
GCC array-bounds warns that ipc_coredump_get_list() under-allocates the size of struct iosm_cd_table *cd_table. This is avoidable - we just need a flexible array. Nothing calls sizeof() on struct iosm_cd_list or anything that contains it.

2022-05-20amt: fix gateway mode stuckTaehee Yoo1-2/+4
If a gateway can not receive any response to requests from a relay, gateway resets status from SENT_REQUEST to INIT and variable about a relay as well. And then it should start the full establish step from sending a discovery message and receiving advertisement message. But, after failure in amt_req_work() it continues sending a request message step with flushed(invalid) relay information and sets SENT_REQUEST. So, a gateway can't be established with a relay. In order to avoid this situation, it stops sending the request message step if it fails.

2022-05-20net: ipa: save a copy of endpoint default configAlex Elder3-28/+28
All elements of the default endpoint configuration are used in the code when programming an endpoint for use. But none of the other configuration data is ever needed once things are initialized. So rather than saving a pointer to *all* of the configuration data, save a copy of only the endpoint configuration portion. This will eventually allow endpoint configuration to be modifiable at runtime. But even before that it means we won't keep a pointer to configuration data after when no longer needed.

If we program an RX endpoint to have no header (header length is 0), header-related endpoint configuration values are meaningless and are ignored. The only case we support that defines a header is QMAP endpoints. In ipa_endpoint_init_hdr_ext() we set the endianness mask value unconditionally, but it should not be done if there is no header (meaning it is not configured for QMAP). Set the endianness conditionally, and rearrange the logic in that function slightly to avoid testing the qmap flag twice. Delete an incorrect comment in ipa_endpoint_init_aggr().

Completion processing for that transaction (and any other "new" ones) will not occur until after this function returns, so there's no risk it completing early. So there's no need to take and drop the additional transaction reference. Use local variables in the call to gsi_evt_ring_doorbell().

2022-05-19net: macb: Fix PTP one step sync supportHarini Katakam2-5/+39
PTP one step sync packets cannot have CSUM padding and insertion in SW since time stamp is inserted on the fly by HW. In addition, ptp4l version 3.0 and above report an error when skb timestamps are reported for packets that not processed for TX TS after transmission. Add a helper to identify PTP one step sync and fix the above two errors. Add a common mask for PTP header flag field "twoStepflag". Also reset ptp OSS bit when one step is not selected.

2022-05-19can: mcp251xfd: silence clang's -Wunaligned-access warningVincent Mailhol1-1/+1
clang emits a -Wunaligned-access warning on union mcp251xfd_tx_ojb_load_buf. The reason is that field hw_tx_obj (not declared as packed) is being packed right after a 16 bits field inside a packed struct: | union mcp251xfd_tx_obj_load_buf { | struct __packed { | struct mcp251xfd_buf_cmd cmd; | /* ^ 16 bits fields */ | struct mcp251xfd_hw_tx_obj_raw hw_tx_obj; | /* ^ not declared as packed */ | } nocrc; | struct __packed { | struct mcp251xfd_buf_cmd_crc cmd; | struct mcp251xfd_hw_tx_obj_raw hw_tx_obj; | __be16 crc; | } crc; | } ____cacheline_aligned; Starting from LLVM 14, having an unpacked struct nested in a packed struct triggers a warning. c.f. [1]. This is a false positive because the field is always being accessed with the relevant put_unaligned_*() function. Adding __packed to the structure declaration silences the warning.

Since commit 30f3b42147ba6f ("can: mark led trigger as broken") the CAN specific LED support was disabled and marked as BROKEN. As the common LED support with CONFIG_LEDS_TRIGGER_NETDEV should do this work now the code can be removed as preparation for a CAN netdevice Kconfig rework.

We want to remove the weight argument from the basic version of the netif_napi_add() call. Move all the callers in drivers/net/can that pass a custom weight (i.e. not NAPI_POLL_WEIGHT or 64) to the netif_napi_add_weight() API.
