Merge tag 'net-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski: "Including fixes from bluetooth, bpf, can and netfilter. A little larger than usual but it's all fixes, no late features. It's large partially because of timing, and partially because of follow ups to stuff that got merged a week or so before the merge window and wasn't as widely tested. Maybe the Bluetooth fixes are a little alarming so we'll address that, but the rest seems okay and not scary. Notably we're including a fix for the netfilter Kconfig [1], your WiFi warning [2] and a bluetooth fix which should unblock syzbot [3]. Current release - regressions: - Bluetooth: - don't try to cancel uninitialized works [3] - L2CAP: fix use-after-free caused by l2cap_chan_put - tls: rx: fix device offload after recent rework - devlink: fix UAF on failed reload and leftover locks in mlxsw Current release - new code bugs: - netfilter: - flowtable: fix incorrect Kconfig dependencies [1] - nf_tables: fix crash when nf_trace is enabled - bpf: - use proper target btf when exporting attach_btf_obj_id - arm64: fixes for bpf trampoline support - Bluetooth: - ISO: unlock on error path in iso_sock_setsockopt() - ISO: fix info leak in iso_sock_getsockopt() - ISO: fix iso_sock_getsockopt for BT_DEFER_SETUP - ISO: fix memory corruption on iso_pinfo.base - ISO: fix not using the correct QoS - hci_conn: fix updating ISO QoS PHY - phy: dp83867: fix get nvmem cell fail Previous releases - regressions: - wifi: cfg80211: fix validating BSS pointers in __cfg80211_connect_result [2] - atm: bring back zatm uAPI after ATM had been removed - properly fix old bug making bonding ARP monitor mode not being able to work with software devices with lockless Tx - tap: fix null-deref on skb->dev in dev_parse_header_protocol - revert "net: usb: ax88179_178a needs FLAG_SEND_ZLP" it helps some devices and breaks others - netfilter: - nf_tables: many fixes rejecting cross-object linking which may lead to UAFs - nf_tables: fix null deref due to zeroed list head - nf_tables: validate variable length element extension - bgmac: fix a BUG triggered by wrong bytes_compl - bcmgenet: indicate MAC is in charge of PHY PM Previous releases - always broken: - bpf: - fix bad pointer deref in bpf_sys_bpf() injected via test infra - disallow non-builtin bpf programs calling the prog_run command - don't reinit map value in prealloc_lru_pop - fix UAFs during the read of map iterator fd - fix invalidity check for values in sk local storage map - reject sleepable program for non-resched map iterator - mptcp: - move subflow cleanup in mptcp_destroy_common() - do not queue data on closed subflows - virtio_net: fix memory leak inside XDP_TX with mergeable - vsock: fix memory leak when multiple threads try to connect() - rework sk_user_data sharing to prevent psock leaks - geneve: fix TOS inheriting for ipv4 - tunnels & drivers: do not use RT_TOS for IPv6 flowlabel - phy: c45 baset1: do not skip aneg configuration if clock role is not specified - rose: avoid overflow when /proc displays timer information - x25: fix call timeouts in blocking connects - can: mcp251x: fix race condition on receive interrupt - can: j1939: - replace user-reachable WARN_ON_ONCE() with netdev_warn_once() - fix memory leak of skbs in j1939_session_destroy() Misc: - docs: bpf: clarify that many things are not uAPI - seg6: initialize induction variable to first valid array index (to silence clang vs objtool warning) - can: ems_usb: fix clang 14's -Wunaligned-access warning" * tag 'net-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (117 commits) net: atm: bring back zatm uAPI dpaa2-eth: trace the allocated address instead of page struct net: add missing kdoc for struct genl_multicast_group::flags nfp: fix use-after-free in area_cache_get() MAINTAINERS: use my korg address for mt7601u mlxsw: minimal: Fix deadlock in ports creation bonding: fix reference count leak in balance-alb mode net: usb: qmi_wwan: Add support for Cinterion MV32 bpf: Shut up kern_sys_bpf warning. net/tls: Use RCU API to access tls_ctx->netdev tls: rx: device: don't try to copy too much on detach tls: rx: device: bound the frag walk net_sched: cls_route: remove from list when handle is 0 selftests: forwarding: Fix failing tests with old libnet net: refactor bpf_sk_reuseport_detach() net: fix refcount bug in sk_psock_get (2) selftests/bpf: Ensure sleepable program is rejected by hash map iter selftests/bpf: Add write tests for sk local storage map iterator selftests/bpf: Add tests for reading a dangling map iter fd bpf: Only allow sleepable program for resched-able iterator ...
