2025-01-14tcp: add TCP_RFC7323_PAWS_ACK drop reasonEric Dumazet
XPS can cause reorders because of the relaxed OOO conditions for pure ACK packets. For hosts not using RFS, what can happpen is that ACK packets are sent on behalf of the cpu processing NIC interrupts, selecting TX queue A for ACK packet P1. Then a subsequent sendmsg() can run on another cpu. TX queue selection uses the socket hash and can choose another queue B for packets P2 (with payload). If queue A is more congested than queue B, the ACK packet P1 could be sent on the wire after P2. A linux receiver when processing P1 (after P2) currently increments LINUX_MIB_PAWSESTABREJECTED (TcpExtPAWSEstab) and use TCP_RFC7323_PAWS drop reason. It might also send a DUPACK if not rate limited. In order to better understand this pattern, this patch adds a new drop_reason : TCP_RFC7323_PAWS_ACK. For old ACKS like these, we no longer increment LINUX_MIB_PAWSESTABREJECTED and no longer sends a DUPACK, keeping credit for other more interesting DUPACK. perf record -e skb:kfree_skb -a perf script ... swapper 0 [148] 27475.438637: skb:kfree_skb: ... location=tcp_validate_incoming+0x4f0 reason: TCP_RFC7323_PAWS_ACK swapper 0 [208] 27475.438706: skb:kfree_skb: ... location=tcp_validate_incoming+0x4f0 reason: TCP_RFC7323_PAWS_ACK swapper 0 [208] 27475.438908: skb:kfree_skb: ... location=tcp_validate_incoming+0x4f0 reason: TCP_RFC7323_PAWS_ACK swapper 0 [148] 27475.439010: skb:kfree_skb: ... location=tcp_validate_incoming+0x4f0 reason: TCP_RFC7323_PAWS_ACK swapper 0 [148] 27475.439214: skb:kfree_skb: ... location=tcp_validate_incoming+0x4f0 reason: TCP_RFC7323_PAWS_ACK swapper 0 [208] 27475.439286: skb:kfree_skb: ... location=tcp_validate_incoming+0x4f0 reason: TCP_RFC7323_PAWS_ACK ...

2025-01-14net: pse-pd: Remove is_enabled callback from driversKory Maincent

2025-01-14net: pse-pd: Split ethtool_get_status into multiple callbacksKory Maincent
The ethtool_get_status callback currently handles all status and PSE information within a single function. This approach has two key drawbacks: 1. If the core requires some information for purposes other than ethtool_get_status, redundant code will be needed to fetch the same data from the driver (like is_enabled). 2. Drivers currently have access to all information passed to ethtool. New variables will soon be added to ethtool status, such as PSE ID, power domain IDs, and budget evaluation strategies, which are meant to be managed solely by the core. Drivers should not have the ability to modify these variables. To resolve these issues, ethtool_get_status has been split into multiple callbacks, with each handling a specific piece of information required by ethtool or the core.

2025-01-14i2c: add core-managed per-client directory in debugfsWolfram Sang
More and more I2C client drivers use debugfs entries and currently they need to manage a subdir for their files on their own. This means inconsistent naming for these subdirs and they are scattered all over the debugfs-tree as well. Not to mention the duplicated code. Let the I2C core provide and maintain a proper directory per client. Note: It was considered to save the additional pointer in 'struct i2c_client' and only provide a subdir when requested via a helper function. When sketching this approach, more and more corner cases appeared, though, so the current solution with its simple and unabiguous code was chosen.

2025-01-14net: ti: icssg-prueth: Add Multicast Filtering support for VLAN in MAC modeMD Danish Anwar
Add multicast filtering support for VLAN interfaces in dual EMAC mode for ICSSG driver. The driver uses vlan_for_each() API to get the list of available vlans. The driver then sync mc addr of vlan interface with a locally mainatined list emac->vlan_mcast_list[vid] using __hw_addr_sync_multiple() API. __hw_addr_sync_multiple() is used instead of __hw_addr_sync() to sync vdev->mc with local list because the sync_cnt for addresses in vdev->mc will already be set by the vlan_dev_set_rx_mode() [net/8021q/vlan_dev.c] and __hw_addr_sync() only syncs when the sync_cnt == 0. Whereas __hw_addr_sync_multiple() can sync addresses even if sync_cnt is not 0. Export __hw_addr_sync_multiple() so that driver can use it. Once the local list is synced, driver calls __hw_addr_sync_dev() with the local list, vdev, sync and unsync callbacks. __hw_addr_sync_dev() is used with the local maintained list as the list to synchronize instead of using __dev_mc_sync() on vdev because __dev_mc_sync() on vdev will call __hw_addr_sync_dev() on vdev->mc and sync_cnt for addresses in vdev->mc will already be set by the vlan_dev_set_rx_mode() [net/8021q/vlan_dev.c] and __hw_addr_sync_dev() only syncs if the sync_cnt of addresses in the list (vdev->mc in this case) is 0. Whereas __hw_addr_sync_dev() on local list will work fine as the sync_cnt for addresses in the local list will still be 0. Based on change in addresses in the local list, sync / unsync callbacks are invoked. In the sync / unsync API in driver, based on whether the ndev is vlan or not, driver passes appropriate vid to FDB helper functions.

Introduce support for standardized PHY statistics reporting in ethtool by extending the PHYLIB framework.

These functions are used within the ethtool implementation to avoid direct access to the phy_device structure outside of the PHYLIB framework. A new structure, ethtool_phy_stats, is introduced to standardize PHY statistics such as packet counts, byte counts, and error counters. Drivers are updated to include callbacks for retrieving PHY and link-specific statistics, ensuring values are explicitly set only for supported fields, initialized with ETHTOOL_STAT_NOT_SET to avoid ambiguity.

THe md-linear is removed by commit 849d18e27be9 ("md: Remove deprecated CONFIG_MD_LINEAR") because it has been marked as deprecated for a long time. However, md-linear is used widely for underlying disks with different size, sadly we didn't know this until now, and it's true useful to create partitions and assemble multiple raid and then append one to the other. People have to use dm-linear in this case now, however, they will prefer to minimize the number of involved modules.

2025-01-13wifi: mac80211: Support dynamic link addition and removalIlan Peer
Add support for adding and removing station links: - Adding links is done asynchronously, i.e., first an ML reconfiguration action frame is sent to the AP requesting to add links, and only when the AP replies, links which were added successfully by the AP are added locally. - Removing links is done synchronously, i.e., the links are removed before sending the ML reconfiguration action frame to the AP (to avoid using this links after the AP MLD removed them but before the station got the ML reconfiguration response). In case the AP replies with a status indicating that a link removal was not successful, disconnect (as this should not happen an is an indication that something might be wrong on the AP MLD).

2025-01-13wifi: mac80211: add some support for RX OMI power savingJohannes Berg
In order to save power, it can be desirable to change the RX operating mode using OMI to reduce the bandwidth. As the handshake must be done in the HTC+ field, it cannot be done by mac80211 directly, so expose functions to the driver to request and finalize the necessary updates. Note that RX OMI really only changes what the peer (AP) will transmit to us, but in order to use it to actually save some power (by reducing the listen bandwidth) we also update rate scaling and then the channel context's mindef accordingly. The updates are split into two in order to sequence them correctly, when reducing bandwidth first reduce the rate scaling and thus TX, then send OMI, then reduce the listen bandwidth (chandef); when increasing bandwidth this is the other way around. This also requires tracking in different variables which part is applicable already.

Current ASoC is using dai_link->dai_fmt to set DAI format for both CPU/Codec. But because it is using same settings, and SND_SOC_DAIFMT_CLOCK_PROVIDER is flipped for CPU, we can't set both CPU/Codec as clock consumer, for example. To solve this issue, this patch enable to use extra format for each DAI which can keep compatibility with legacy system, 1. SND_SOC_DAIFMT_FORMAT_MASK 2. SND_SOC_DAIFMT_CLOCK 3. SND_SOC_DAIFMT_INV 4.
