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:David S.

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.

The 1588 timer on eTSEC Ethernet controller uses different register memory map with DPAA Ethernet controller. Now the new ENETC Ethernet controller uses same reigster memory map with DPAA. To support ENETC, let's use register memory map of DPAA/ENETC in default. Signed-off-by:

There is QorIQ 1588 timer IP block on the new ENETC Ethernet controller. However it uses little endian mode which is different with before. This patch is to add little endian support for the driver by using "little-endian" dts node property. Signed-off-by:

Moved QorIQ PTP clock initialization/free into new functions ptp_qoriq_init()/ptp_qoriq_free(). These functions could also be reused by ENETC PTP drvier which is a PCI driver for same 1588 timer IP block. Signed-off-by:

Strings containing "ptp_qoriq" or "qoriq_ptp" which were used for structure/function names were complained by users. Let's just use the unique "ptp_qoriq" to make these names more consistent. This patch is just to unify the names using "ptp_qoriq". It hasn't changed any functions. Signed-off-by:

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:

Florian Fainelli says: ==================== Remove getting SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS AFAICT there is no code that attempts to get the value of the attribute SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS while it is used with switchdev_port_attr_set(). This is effectively no doing anything and it can slow down future work that tries to make modifications in these areas so remove that. ==================== 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: -
Christoph Hellwig authored
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:

Also use GFP_KERNEL instead of GFP_ATOMIC as the gfp_t for the memory allocation, as we aren't in interrupt context or under a lock. Signed-off-by:
