Current code enqueues & dequeues a reply object from the waiter list in various places. In particular, the dequeue & enqueue in qeth_send_control_data_cb() looks fragile - this can cause qeth_clear_ipacmd_list() to skip the active object. Add some helpers, and boil the logic down by giving qeth_send_control_data() the sole responsibility to add and remove objects. qeth_send_control_data_cb() and qeth_clear_ipacmd_list() will now only notify the reply object to interrupt its wait cycle. This can cause a slight delay in the removal, but that's no concern. Signed-off-by:

csum offload and TSO have similar programming requirements. The TSO code was reworked with commit "s390/qeth: enhance TSO control sequence", adjust the csum control flow accordingly. Primarily this means replacing custom helpers with more generic infrastructure. Also, change the LP2LP check so that it warns on TX offload (not RX). This is where reduced csum capability actually matters. Signed-off-by:

The code to fill the IPA length fields is duplicated three times across the driver: 1. qeth_send_ipa_cmd() sets IPA_CMD_LENGTH, which matches the defaults in the IPA_PDU_HEADER template. 2. for OSN, qeth_osn_send_ipa_cmd() bypasses this logic and inserts the length passed by the caller. 3. SNMP commands (that can outgrow IPA_CMD_LENGTH) have their own way of setting the length fields, via qeth_send_ipa_snmp_cmd(). Consolidate this into qeth_prepare_ipa_cmd(), which all originators of IPA cmds already call during setup of their cmd. Let qeth_send_ipa_cmd() pull the length from the cmd instead of hard-coding IPA_CMD_LENGTH. For now, the SNMP code still needs to fix-up its length fields manually. Signed-off-by:

qeth_l3_query_arp_cache_info() indicates a data length that's much larger than the actual length of its request (ie. the value passed to qeth_get_setassparms_cmd()). The confusion presumably comes from the fact that the cmd _response_ can be quite large - but that's no concern for the initial request IO. Fixing this up allows us to use the generic qeth_send_ipa_cmd() infrastructure. Signed-off-by:

Yangbo Lu says: ==================== Add ENETC PTP clock driver There is same QorIQ 1588 timer IP block on the new ENETC Ethernet controller with eTSEC/DPAA Ethernet controllers. However it's different endianness (little-endian) and using PCI driver. To support ENETC PTP driver, ptp_qoriq driver needed to be reworked to make functions global for reusing, to add little- endian support, to add ENETC memory map support, and to add ENETC dependency for ptp_qoriq driver. In addition, although ENETC PTP driver is a PCI driver, the dts node still could be used. Currently the ls1028a dtsi which is the only platform by now using ENETC is not complete, so there is still dependency for ENETC PTP node upstreaming. This will be done in the near future. The hardware timestamping support for ENETC is done but needs to be reworked with new method in internal git tree, and will be sent out soon. ==================== Signed-off-by:

When an ethernet frame is padded to meet the minimum ethernet frame size, the padding octets are not covered by the hardware checksum. Fortunately the padding octets are usually zero's, which don't affect checksum. However, it is not guaranteed. For example, switches might choose to make other use of these octets. This repeatedly causes kernel hardware checksum fault. Prior to the cited commit below, skb checksum was forced to be CHECKSUM_NONE when padding is detected. After it, we need to keep skb->csum updated. However, fixing up CHECKSUM_COMPLETE requires to verify and parse IP headers, it does not worth the effort as the packets are so small that CHECKSUM_COMPLETE has no significant advantage. Future work: when reporting checksum complete is not an option for IP non-TCP/UDP packets, we can actually fallback to report checksum unnecessary, by looking at cqe IPOK bit.

There are several skb_* functions where the locked and unlocked functions are confusingly documented. For several of them, the kernel-doc for the unlocked version is placed above the locked version, which to the casual reader makes it seems like the locked version "takes no locks and you must therefore hold required locks before calling it." One can see, for example, that this link claims to document skb_queue_head(), while instead describing __skb_queue_head(). https://www.kernel.org/doc/html/latest/networking/kapi.html#c.skb_queue_head The correct documentation for skb_queue_head() is also included further down the page. This diff tested via: $ scripts/kernel-doc -rst include/linux/skbuff.h net/core/skbuff.c No new warnings were seen, and the output makes a little more sense. Signed-off-by:

Addition of tls1.3 support broke tls1.2 handshake when async crypto accelerator is used. This is because the record type for non-data records is not propagated to user application. Also when async decryption happens, the decryption does not stop when two different types of records get dequeued and submitted for decryption. To address it, we decrypt tls1.2 non-data records in synchronous way. We check whether the record we just processed has same type as the previous one before checking for async condition and jumping to dequeue next record.

Christoph Hellwig says: ==================== net: don't pass a NULL struct device to DMA API functions v2 We still have a few drivers which pass a NULL struct device pointer to DMA API functions, which generally is a bad idea as the API implementations rely on the device not only for ops selection, but also the dma mask and various other attributes. This series contains all easy conversions to pass a struct device, besides that there also is some arch code that needs separate handling, a driver that should not use the DMA API at all, and one that is a complete basket case to be deal with separately. Changes since v1: - fix an inverted ifdef in CAIF - update the smc911x changelog - split the series, this only contains the networking patches ==================== Signed-off-by:

The DMA API generally relies on a struct device to work properly, and only barely works without one for legacy reasons. Pass the easily available struct device from the platform_device to remedy this. Note that smc911x apparently is a PIO chip with an external DMA handshake, and we probably use the wrong device here. But at least it matches the mapping side, which apparently works or at least worked in the not too distant past. Signed-off-by:
