KERNEL 7.2 SHIPPING WITH BPF ARENA BREAKTHROUGH AND NETWORKING OVERHAUL

By RepoJournal · Filed 06:02 UTC on June 18, 2026 · About Linux

BPF kfuncs can now access arena pointers directly after the kernel lands fault recovery on scratch pages, while the networking stack continues its multi-cycle assault on rtnl_lock contention.

The merge window closes with major architectural work across three pillars. BPF gets its most significant arena upgrade yet [1]: lockless empty-slot installs via ptep_try_set() on x86 and arm64 eliminate a class of page fault crashes that blocked production use of direct arena access. This lands after careful cross-tree coordination with sched-ext, unblocking kfunc patterns that were previously off the table. Networking continues its systematic rtnl_lock removal campaign [2], with IPv6 multicast routing and ethtool now operating without the global lock on modern drivers. Qdisc dump callbacks are being refactored in preparation for the next phase. SELinux hardens policy loading with additional verification stages [3], addressing validation gaps in the policy parser that Christian Göttsche identified. LSM gets a cleanup [4] that leverages existing xattr helpers after NFS code shipped in v7.0. DRM rounds out the merge with xe platform support and amdgpu HDMI 2.1 FRL handling [5], plus a scheduler fairness rewrite that affects every GPU workload on the tree.
