2025-06-18net: ena: Add PHC support in the ENA driverDavid Arinzon
The ENA driver will be extended to support the new PHC feature using ptp_clock interface [1]. this will provide timestamp reference for user space to allow measuring time offset between the PHC and the system clock in order to achieve nanosecond accuracy.

2025-06-18bpf: Adjust free target to avoid global starvation of LRU mapWillem de Bruijn
BPF_MAP_TYPE_LRU_HASH can recycle most recent elements well before the map is full, due to percpu reservations and force shrink before neighbor stealing. Once a CPU is unable to borrow from the global map, it will once steal one elem from a neighbor and after that each time flush this one element to the global list and immediately recycle it. Batch value LOCAL_FREE_TARGET (128) will exhaust a 10K element map with 79 CPUs. CPU 79 will observe this behavior even while its neighbors hold 78 * 127 + 1 * 15 == 9921 free elements (99%). CPUs need not be active concurrently. The issue can appear with affinity migration, e.g., irqbalance. Each CPU can reserve and then hold onto its 128 elements indefinitely. Avoid global list exhaustion by limiting aggregate percpu caches to half of map size, by adjusting LOCAL_FREE_TARGET based on cpu count. This change has no effect on sufficiently large tables. Similar to LOCAL_NR_SCANS and lru->nr_scans, introduce a map variable lru->free_target. The extra field fits in a hole in struct bpf_lru. The cacheline is already warm where read in the hot path. The field is only accessed with the lru lock held.

2025-06-18net: ethtool: remove duplicate defines for family infoJakub Kicinski
Commit under fixes switched to uAPI generation from the YAML spec. A number of custom defines were left behind, mostly for commands very hard to express in YAML spec. Among what was left behind was the name and version of the generic netlink family. Problem is that the codegen always outputs those values so we ended up with a duplicated, differently named set of defines. Provide naming info in YAML and remove the incorrect defines.

Add binding documentation for i.MX8QXP and i.MX8QM ISI. The clock-names, power-domains, and ports differ significantly from the existing nxp,imx8-isi.yaml. Create a new file to avoid complex if-else branches. Add new file to MAINTAINERS.

2025-06-17tcp: remove RFC3517/RFC6675 hint state: lost_skb_hint, lost_cnt_hintNeal Cardwell
Now that obsolete RFC3517/RFC6675 TCP loss detection has been removed, we can remove the somewhat complex and intrusive code to maintain its hint state: lost_skb_hint and lost_cnt_hint. This commit makes tcp_clear_retrans_hints_partial() empty. We will remove tcp_clear_retrans_hints_partial() and its call sites in the next commit.

2025-06-17tcp: remove obsolete and unused RFC3517/RFC6675 loss recovery codeNeal Cardwell
RACK-TLP loss detection has been enabled as the default loss detection algorithm for Linux TCP since 2018, in: commit b38a51fec1c1 ("tcp: disable RFC6675 loss detection") In case users ran into unexpected bugs or performance regressions, that commit allowed Linux system administrators to revert to using RFC3517/RFC6675 loss recovery by setting net.ipv4.tcp_recovery to 0. In the seven years since 2018, our team has not heard reports of anyone reverting Linux TCP to use RFC3517/RFC6675 loss recovery, and we can't find any record in web searches of such a revert. RACK-TLP was published as a standards-track RFC, RFC8985, in February 2021. Several other major TCP implementations have default-enabled RACK-TLP at this point as well. RACK-TLP offers several significant performance advantages over RFC3517/RFC6675 loss recovery, including much better performance in the common cases of tail drops, lost retransmissions, and reordering. It is now time to remove the obsolete and unused RFC3517/RFC6675 loss recovery code. This will allow a substantial simplification of the Linux TCP code base, and removes 12 bytes of state in every tcp_sock for 64-bit machines (8 bytes on 32-bit machines). To arrange the commits in reasonable sizes, this patch series is split into 3 commits. The following 2 commits remove bookkeeping state and code that is no longer needed after this removal of RFC3517/RFC6675 loss recovery.
