Pull networking fixes from Jakub Kicinski: "Including fixes from bpf, mac80211. Current release - regressions: - devlink: don't throw an error if flash notification sent before devlink visible - page_pool: Revert "page_pool: disable dma mapping support...", turns out there are active arches who need it Current release - new code bugs: - amt: cancel delayed_work synchronously in amt_fini() Previous releases - regressions: - xsk: fix crash on double free in buffer pool - bpf: fix inner map state pruning regression causing program rejections - mac80211: drop check for DONT_REORDER in __ieee80211_select_queue, preventing mis-selecting the best effort queue - mac80211: do not access the IV when it was stripped - mac80211: fix radiotap header generation, off-by-one - nl80211: fix getting radio statistics in survey dump - e100: fix device suspend/resume Previous releases - always broken: - tcp: fix uninitialized access in skb frags array for Rx 0cp - bpf: fix toctou on read-only map's constant scalar tracking - bpf: forbid bpf_ktime_get_coarse_ns and bpf_timer_* in tracing progs - tipc: only accept encrypted MSG_CRYPTO msgs - smc: transfer remaining wait queue entries during fallback, fix missing wake ups - udp: validate checksum in udp_read_sock() (when sockmap is used) - sched: act_mirred: drop dst for the direction from egress to ingress - virtio_net_hdr_to_skb: count transport header in UFO, prevent allowing bad skbs into the stack - nfc: reorder the logic in nfc_{un,}register_device, fix unregister - ipsec: check return value of ipv6_skip_exthdr - usb: r8152: add MAC passthrough support for more Lenovo Docks" * tag 'net-5.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (96 commits) ptp: ocp: Fix a couple NULL vs IS_ERR() checks net: ethernet: dec: tulip: de4x5: fix possible array overflows in type3_infoblock() net: tulip: de4x5: fix the problem that the array 'lp->phy[8]' may be out of bound ipv6: check return value of ipv6_skip_exthdr e100: fix device suspend/resume devlink: Don't throw an error if flash notification sent before devlink visible page_pool: Revert "page_pool: disable dma mapping support..." ethernet: hisilicon: hns: hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port() octeontx2-af: debugfs: don't corrupt user memory NFC: add NCI_UNREG flag to eliminate the race NFC: reorder the logic in nfc_{un,}register_device NFC: reorganize the functions in nci_request tipc: check for null after calling kmemdup i40e: Fix display error code in dmesg i40e: Fix creation of first queue by omitting it if is not power of two i40e: Fix warning message and call stack during rmmod i40e driver i40e: Fix ping is lost after configuring ADq on VF i40e: Fix changing previously set num_queue_pairs for PFs i40e: Fix NULL ptr dereference on VSI filter sync i40e: Fix correct max_pkt_size on VF RX queue ...
