Linus Torvalds 4e04e7513b Networking fixes for 5.12-rc7, including fixes from can, ipsec,
mac80211, wireless, and bpf trees. No scary regressions here
 or in the works, but small fixes for 5.12 changes keep coming.
 
 Current release - regressions:
 
  - virtio: do not pull payload in skb->head
 
  - virtio: ensure mac header is set in virtio_net_hdr_to_skb()
 
  - Revert "net: correct sk_acceptq_is_full()"
 
  - mptcp: revert "mptcp: provide subflow aware release function"
 
  - ethernet: lan743x: fix ethernet frame cutoff issue
 
  - dsa: fix type was not set for devlink port
 
  - ethtool: remove link_mode param and derive link params
             from driver
 
  - sched: htb: fix null pointer dereference on a null new_q
 
  - wireless: iwlwifi: Fix softirq/hardirq disabling in
                       iwl_pcie_enqueue_hcmd()
 
  - wireless: iwlwifi: fw: fix notification wait locking
 
  - wireless: brcmfmac: p2p: Fix deadlock introduced by avoiding
                             the rtnl dependency
 
 Current release - new code bugs:
 
  - napi: fix hangup on napi_disable for threaded napi
 
  - bpf: take module reference for trampoline in module
 
  - wireless: mt76: mt7921: fix airtime reporting and related
                            tx hangs
 
  - wireless: iwlwifi: mvm: rfi: don't lock mvm->mutex when sending
                                 config command
 
 Previous releases - regressions:
 
  - rfkill: revert back to old userspace API by default
 
  - nfc: fix infinite loop, refcount & memory leaks in LLCP sockets
 
  - let skb_orphan_partial wake-up waiters
 
  - xfrm/compat: Cleanup WARN()s that can be user-triggered
 
  - vxlan, geneve: do not modify the shared tunnel info when PMTU
                   triggers an ICMP reply
 
  - can: fix msg_namelen values depending on CAN_REQUIRED_SIZE
 
  - can: uapi: mark union inside struct can_frame packed
 
  - sched: cls: fix action overwrite reference counting
 
  - sched: cls: fix err handler in tcf_action_init()
 
  - ethernet: mlxsw: fix ECN marking in tunnel decapsulation
 
  - ethernet: nfp: Fix a use after free in nfp_bpf_ctrl_msg_rx
 
  - ethernet: i40e: fix receiving of single packets in xsk zero-copy
                    mode
 
  - ethernet: cxgb4: avoid collecting SGE_QBASE regs during traffic
 
 Previous releases - always broken:
 
  - bpf: Refuse non-O_RDWR flags in BPF_OBJ_GET
 
  - bpf: Refcount task stack in bpf_get_task_stack
 
  - bpf, x86: Validate computation of branch displacements
 
  - ieee802154: fix many similar syzbot-found bugs
     - fix NULL dereferences in netlink attribute handling
     - reject unsupported operations on monitor interfaces
     - fix error handling in llsec_key_alloc()
 
  - xfrm: make ipv4 pmtu check honor ip header df
 
  - xfrm: make hash generation lock per network namespace
 
  - xfrm: esp: delete NETIF_F_SCTP_CRC bit from features for esp
               offload
 
  - ethtool: fix incorrect datatype in set_eee ops
 
  - xdp: fix xdp_return_frame() kernel BUG throw for page_pool
         memory model
 
  - openvswitch: fix send of uninitialized stack memory in ct limit
                 reply
 
 Misc:
 
  - udp: add get handling for UDP_GRO sockopt

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
