Asbjørn Sloth Tønnesen says: ==================== flower: rework TCA_FLOWER_KEY_ENC_FLAGS usage This series reworks the recently added TCA_FLOWER_KEY_ENC_FLAGS attribute, to be more like TCA_FLOWER_KEY_FLAGS, and use the unused u32 flags field in FLOW_DISSECTOR_KEY_ENC_CONTROL, instead of adding a new flags field as FLOW_DISSECTOR_KEY_ENC_FLAGS. I have defined the new FLOW_DIS_F_* and TCA_FLOWER_KEY_FLAGS_* flags to co-exist with the existing flags, so the meaning of the flags field in struct flow_dissector_key_control is not depending on the context it is used in. If we run out of bits then we can always split them up later, if we really want to. Future flags might also be valid in both contexts. iproute2 RFC v2 patch: https://lore.kernel.org/560bcd549ca8ab24b1ad5abe352580a621f6d426.1720790774.git.dcaratti@redhat.com/ v3: https://lore.kernel.org/20240709163825.1210046-1-ast@fiberby.net/ v2: https://lore.kernel.org/20240705133348.728901-1-ast@fiberby.net/ v1: https://lore.kernel.org/20240703104600.455125-1-ast@fiberby.net/ RFC: https://lore.kernel.org/20240611235355.177667-1-ast@fiberby.net/ ==================== Link: https://patch.msgid.link/20240713021911.1631517-1-ast@fiberby.netSigned-off-by:

This patch changes how TCA_FLOWER_KEY_ENC_FLAGS is used, so that it is used with TCA_FLOWER_KEY_FLAGS_* flags, in the same way as TCA_FLOWER_KEY_FLAGS is currently used. Where TCA_FLOWER_KEY_FLAGS uses {key,mask}->control.flags, then TCA_FLOWER_KEY_ENC_FLAGS now uses {key,mask}->enc_control.flags, therefore {key,mask}->enc_flags is now unused. As the generic fl_set_key_flags/fl_dump_key_flags() is used with encap set to true, then fl_{set,dump}_key_enc_flags() is removed. This breaks unreleased userspace API (net-next since 2024-06-04).

This policy guards fl_set_key_flags() from seeing flags not used in the context of TCA_FLOWER_KEY_FLAGS. In order For the policy check to be performed with the correct endianness, then we also needs to change the attribute type to NLA_BE32 (Thanks Davide).

Prepare fl_set_key_flags/fl_dump_key_flags() for use with TCA_FLOWER_KEY_ENC_FLAGS{,_MASK}. This patch adds an encap argument, similar to fl_set_key_ip/ fl_dump_key_ip(), and determine the flower keys based on the encap argument, and use them in the rest of the two functions. Since these functions are so far, only called with encap set false, then there is no functional change. Signed-off-by: -

Define new TCA_FLOWER_KEY_FLAGS_* flags for use in struct flow_dissector_key_control, covering the same flags as currently exposed through TCA_FLOWER_KEY_ENC_FLAGS. Put the new flags under FLOW_DIS_F_*. The idea is that we can later, move the existing flags under FLOW_DIS_F_* as well. The ynl flag names have been taken from the RFC iproute2 patch. Signed-off-by:

Asbjørn Sloth Tønnesen authored
Redefine the flower control flags as an enum, so they are included in BTF info. Make the kernel-side enum a more explicit superset of TCA_FLOWER_KEY_FLAGS_*, new flags still need to be added to both enums, but at least the bit position only has to be defined once. FLOW_DIS_ENCAPSULATION is never set for mask, so it can't be exposed to userspace in an unsupported flags mask error message, so it will be placed one bit position above the last uAPI flag.

In prevision to add new UAPI for hwtstamp we will be limited to the struct ethtool_ts_info that is currently passed in fixed binary format through the ETHTOOL_GET_TS_INFO ethtool ioctl. It would be good if new kernel code already started operating on an extensible kernel variant of that structure, similar in concept to struct kernel_hwtstamp_config vs struct hwtstamp_config. Since struct ethtool_ts_info is in include/uapi/linux/ethtool.h, here we introduce the kernel-only structure in include/linux/ethtool.h. The manual copy is then made in the function called by ETHTOOL_GET_TS_INFO. Acked-by:

Change the API to select MAC default time stamping instead of the PHY. Indeed the PHY is closer to the wire therefore theoretically it has less delay than the MAC timestamping but the reality is different. Due to lower time stamping clock frequency, latency in the MDIO bus and no PHC hardware synchronization between different PHY, the PHY PTP is often less precise than the MAC. The exception is for PHY designed specially for PTP case but these devices are not very widespread. For not breaking the compatibility default_timestamp flag has been introduced in phy_device that is set by the phy driver to know we are using the old API behavior. Reviewed-by:

In preparation for using the power sequencing subsystem on sm8650 boards and X13s laptop let's make pwrseq the default for wcn7850 and wcn6855. Both these models require an enable GPIO so we can safely assume that if the property is not there, then we should try to get the power sequencer. Due to how the pwrseq lookup works - checking the provider at run-time - we cannot really do it the other way around as we'd get stuck forever on -EPROBE_DEFER. If the relevant OF node does have the 'enable-gpios' property, we fallback to the existing code for backward compatibility with older DTs. Signed-off-by:

In preparation for unduplicating the hci_uart registration code, schedule a devres action for disabling the SUSCLK rather than doing it manually. We cannot really use devm_clk_get_enabled() as we also set the rate before enabling the clock. While this should in theory work, I don't want to risk breaking existing users. One solution for the future is to add devm_clk_get_enabled_with_rate() to the clock framework. Signed-off-by:

MediaTek defines a specific interrupt endpoint for ISO data transmissin because the characteristics of interrupt endpoint are similar to the application of ISO data which can support guaranteed transmissin bandwidth, enough maximum data length and error checking mechanism. Driver sets up ISO interface and endpoints in btusb_mtk_setup and clears the setup in btusb_mtk_shutdown. These flow can't move to btmtk.c due to btusb_driver is only defined in btusb.c when claiming/relaesing interface.
