Linus Torvalds f54ca91fe6 Networking fixes for 5.16-rc1, including fixes from bpf, can
and netfilter.
 
 Current release - regressions:
 
  - bpf: do not reject when the stack read size is different
    from the tracked scalar size
 
  - net: fix premature exit from NAPI state polling in napi_disable()
 
  - riscv, bpf: fix RV32 broken build, and silence RV64 warning
 
 Current release - new code bugs:
 
  - net: fix possible NULL deref in sock_reserve_memory
 
  - amt: fix error return code in amt_init(); fix stopping the workqueue
 
  - ax88796c: use the correct ioctl callback
 
 Previous releases - always broken:
 
  - bpf: stop caching subprog index in the bpf_pseudo_func insn
 
  - security: fixups for the security hooks in sctp
 
  - nfc: add necessary privilege flags in netlink layer, limit operations
    to admin only
 
  - vsock: prevent unnecessary refcnt inc for non-blocking connect
 
  - net/smc: fix sk_refcnt underflow on link down and fallback
 
  - nfnetlink_queue: fix OOB when mac header was cleared
 
  - can: j1939: ignore invalid messages per standard
 
  - bpf, sockmap:
    - fix race in ingress receive verdict with redirect to self
    - fix incorrect sk_skb data_end access when src_reg = dst_reg
    - strparser, and tls are reusing qdisc_skb_cb and colliding
 
  - ethtool: fix ethtool msg len calculation for pause stats
 
  - vlan: fix a UAF in vlan_dev_real_dev() when ref-holder tries
    to access an unregistering real_dev
 
  - udp6: make encap_rcv() bump the v6 not v4 stats
 
  - drv: prestera: add explicit padding to fix m68k build
 
  - drv: felix: fix broken VLAN-tagged PTP under VLAN-aware bridge
 
  - drv: mvpp2: fix wrong SerDes reconfiguration order
 
 Misc & small latecomers:
 
  - ipvs: auto-load ipvs on genl access
 
  - mctp: sanity check the struct sockaddr_mctp padding fields
 
  - libfs: support RENAME_EXCHANGE in simple_rename()
 
  - avoid double accounting for pure zerocopy skbs

README

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.
