Add dts support for Motorcomm yt8531s gigabit ethernet phy. Change yt8521_probe to support clk config of yt8531s. Becase yt8521_probe does the things which yt8531s is needed, so removed yt8531s function. This patch has been verified on AM335x platform with yt8531s board. Signed-off-by:

Vlad Buslov says: ==================== net: Allow offloading of UDP NEW connections via act_ct Currently only bidirectional established connections can be offloaded via act_ct. Such approach allows to hardcode a lot of assumptions into act_ct, flow_table and flow_offload intermediate layer codes. In order to enabled offloading of unidirectional UDP NEW connections start with incrementally changing the following assumptions: - Drivers assume that only established connections are offloaded and don't support updating existing connections. Extract ctinfo from meta action cookie and refuse offloading of new connections in the drivers. - Fix flow_table offload fixup algorithm to calculate flow timeout according to current connection state instead of hardcoded "established" value. - Add new flow_table flow flag that designates bidirectional connections instead of assuming it and hardcoding hardware offload of every flow in both directions. - Add new flow_table flow flag that designates connections that are offloaded to hardware as "established" instead of assuming it. This allows some optimizations in act_ct and prevents spamming the flow_table workqueue with redundant tasks. With all the necessary infrastructure in place modify act_ct to offload UDP NEW as unidirectional connection. Pass reply direction traffic to CT and promote connection to bidirectional when UDP connection state changes to "assured". Rely on refresh mechanism to propagate connection state change to supporting drivers. Note that early drop algorithm that is designed to free up some space in connection tracking table when it becomes full (by randomly deleting up to 5% of non-established connections) currently ignores connections marked as "offloaded". Now, with UDP NEW connections becoming "offloaded" it could allow malicious user to perform DoS attack by filling the table with non-droppable UDP NEW connections by sending just one packet in single direction. To prevent such scenario change early drop algorithm to also consider "offloaded" connections for deletion. ==================== Signed-off-by: -

Both synchronous early drop algorithm and asynchronous gc worker completely ignore connections with IPS_OFFLOAD_BIT status bit set. With new functionality that enabled UDP NEW connection offload in action CT malicious user can flood the conntrack table with offloaded UDP connections by just sending a single packet per 5tuple because such connections can no longer be deleted by early drop algorithm. To mitigate the issue allow both early drop and gc to consider offloaded UDP connections for deletion. Signed-off-by:

Modify the offload algorithm of UDP connections to the following: - Offload NEW connection as unidirectional. - When connection state changes to ESTABLISHED also update the hardware flow. However, in order to prevent act_ct from spamming offload add wq for every packet coming in reply direction in this state verify whether connection has already been updated to ESTABLISHED in the drivers. If that it the case, then skip flow_table and let conntrack handle such packets which will also allow conntrack to potentially promote the connection to ASSURED. - When connection state changes to ASSURED set the flow_table flow NF_FLOW_HW_BIDIRECTIONAL flag which will cause refresh mechanism to offload the reply direction. All other protocols have their offload algorithm preserved and are always offloaded as bidirectional. Note that this change tries to minimize the load on flow_table add workqueue. First, it tracks the last ctinfo that was offloaded by using new flow 'NF_FLOW_HW_ESTABLISHED' flag and doesn't schedule the refresh for reply direction packets when the offloads have already been updated with current ctinfo. Second, when 'add' task executes on workqueue it always update the offload with current flow state (by checking 'bidirectional' flow flag and obtaining actual ctinfo/cookie through meta action instead of caching any of these from the moment of scheduling the 'add' work) preventing the need from scheduling more updates if state changed concurrently while the 'add' work was pending on workqueue.

Currently tcf_ct_flow_table_fill_actions() function assumes that only established connections can be offloaded and always sets ctinfo to either IP_CT_ESTABLISHED or IP_CT_ESTABLISHED_REPLY strictly based on direction without checking actual connection state. To enable UDP NEW connection offload set the ctinfo, metadata cookie and NF_FLOW_HW_ESTABLISHED flow_offload flags bit based on ct->status value. Signed-off-by:

Modify flow table offload to cache the last ct info status that was passed to the driver offload callbacks by extending enum nf_flow_flags with new "NF_FLOW_HW_ESTABLISHED" flag. Set the flag if ctinfo was 'established' during last act_ct meta actions fill call.

Vlad Buslov authored
In order to offload connections in other states besides "established" the driver offload callbacks need to have access to connection conntrack info. Flow offload intermediate representation data structure already contains that data encoded in 'cookie' field, so just reuse it in the drivers. Reject offloading IP_CT_NEW connections for now by returning an error in relevant driver callbacks based on value of ctinfo. Support for offloading such connections will need to be added to the drivers afterwards. Signed-off-by:

Yoshihiro Shimoda says: ==================== net: renesas: rswitch: Modify initialization for SERDES and PHY - My platform has the 88x2110. - The MACTYPE setting of strap pin on the platform is SXGMII. - However, we realized that the SoC cannot communicate the PHY with SXGMII because of mismatching hardware specification. - We have a lot of boards which mismatch the MACTYPE setting. So, I would like to change the MACTYPE as SGMII by software for the platform. The patch [1/5] sets phydev->host_interfaces by phylink for Marvell PHY driver (marvell10g) to initialize the MACTYPE. - The patch [1/5] siplifies the rswitch driver. - The patch [2/5] converts to phy_device from phylink. - The patch [3/5] sets phydev->host_interfaces from this driver without any new functions of phylib. - The patch [4/5] adds phy_power_on() calling to initialize the Ethernet SERDES PHY driver (r8a779f0-eth-serdes) for each channel. - The patch [5/5] adds "max-speed" handling. Changes from v4: https://lore.kernel.org/all/20230127142621.1761278-1-yoshihiro.shimoda.uh@renesas.com/ - No modification of phylink API. - Convert to phylib instead of phylink. - Add "max-speed" handling.

Some Ethernet PHYs (like marvell10g) will decide the host interface mode by the media-side speed. So, the rswitch driver needs to initialize one of the Ethernet SERDES (r8a779f0-eth-serdes) ports after linked the Ethernet PHY up. The r8a779f0-eth-serdes driver has .init() for initializing all ports and .power_on() for initializing each port. So, add phy_power_{on,off} calling for it. Signed-off-by: -

Conversion to gpiod API done in commit 468ba54b ("fec: convert to gpio descriptor") clashed with gpiolib applying the same quirk to the reset GPIO polarity (introduced in commit b02c85c9). This results in the reset line being left active/device being left in reset state when reset line is "active low". Remove handling of 'phy-reset-active-high' property from the driver and rely on gpiolib to apply needed adjustments to avoid ending up with the double inversion/flipped logic.

Pull s390 fixes from Heiko Carstens: - With CONFIG_VMAP_STACK enabled it is not possible to load the s390 specific diag288_wdt watchdog module. The reason is that a pointer to a string is passed to an inline assembly; this string however is located on the stack, while the instruction within the inline assembly expects a physicial address. Fix this by copying the string to a kmalloc'ed buffer. - The diag288_wdt watchdog module does not indicate that it accesses memory from an inline assembly, which it does. Add "memory" to the clobber list to prevent the compiler from optimizing code incorrectly away. - Pass size of the uncompressed kernel image to __decompress() call. Otherwise the kernel image decompressor may corrupt/overwrite an initrd. This was reported to happen on s390 after commit 2aa14b1a ("zstd: import usptream v1.5.2"). * tag 's390-6.2-4' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390/decompressor: specify __decompress() buf len to avoid overflow watchdog: diag288_wdt: fix __diag288() inline assembly watchdog: diag288_wdt: do not use stack buffers for hardware data

The code expect the PHY to be in power down which is only true after reset. Allow changes of the SGMII parameters more than once. Only power down when reconfiguring to avoid bouncing the link when there's no reason to - based on code from Russell King. There are cases when the SGMII_PHYA_PWD register contains 0x9 which prevents SGMII from working. The SGMII still shows link but no traffic can flow.

According to my tests on MT7621AT and MT7623NI SoCs, hardware DSA untagging won't work on the second MAC. Therefore, disable this feature when the second MAC of the MT7621 and MT7623 SoCs is being used.
