6a5df969ff docs: bpf: Clarify BPF_CMPXCHG wording
Based on [1], BPF_CMPXCHG should always load the old value into R0. The
phrasing in bpf.rst is somewhat ambiguous in this regard, improve it to
make this aspect crystal clear.

628add78b0 bpf, docs: Update build procedure for manually compiling LLVM and Clang
The current LLVM and Clang build procedure in samples/bpf/README.rst is
out of date. See below that the links are not accessible any more.

  $ git clone http://llvm.org/git/llvm.git
  Cloning into 'llvm'...
  fatal: unable to access 'http://llvm.org/git/llvm.git/': Maximum (20) redirects followed
  $ git clone --depth 1 http://llvm.org/git/clang.git
  Cloning into 'clang'...
  fatal: unable to access 'http://llvm.org/git/clang.git/': Maximum (20) redirects followed

The LLVM community has adopted new ways to build the compiler. There are
different ways to build LLVM and Clang, the Clang Getting Started page [1]
has one way. As Yonghong said, it is better to copy the build procedure
in Documentation/bpf/bpf_devel_QA.rst to keep consistent.

I verified the procedure and it is proved to be feasible, so we should
update README.rst to reflect the reality. At the same time, update the
related comment in Makefile.

Additionally, as Fangrui said, the dir llvm-project/llvm/build/install is
not used, BUILD_SHARED_LIBS=OFF is the default option [2], so also change
Documentation/bpf/bpf_devel_QA.rst together.

At last, we recommend that developers who want the fastest incremental
builds use the Ninja build system [1], you can find it in your system's
package manager, usually the package is ninja or ninja-build [3], so add
ninja to build dependencies suggested by Nathan.

6939f4ef16 trace: bpf: Allow bpf to attach to bare tracepoints
Some subsystems only have bare tracepoints (a tracepoint with no
associated trace event) to avoid the problem of trace events being an
ABI that can't be changed.

>From bpf presepective, bare tracepoints are what it calls
RAW_TRACEPOINT().

Since bpf assumed there's 1:1 mapping, it relied on hooking to
DEFINE_EVENT() macro to create bpf mapping of the tracepoints. Since
bare tracepoints use DECLARE_TRACE() to create the tracepoint, bpf had
no knowledge about their existence.

By teaching bpf_probe.h to parse DECLARE_TRACE() in a similar fashion to
DEFINE_EVENT(), bpf can find and attach to the new raw tracepoints.

Enabling that comes with the contract that changes to raw tracepoints
don't constitute a regression if they break existing bpf programs.
We need the ability to continue to morph and modify these raw
tracepoints without worrying about any ABI.

Update Documentation/bpf/bpf_design_QA.rst to document this contract.

7b8fc0103b bonding: add a vlan+srcmac tx hashing option
This comes from an end-user request, where they're running multiple VMs on
hosts with bonded interfaces connected to some interest switch topologies,
where 802.3ad isn't an option. They're currently running a proprietary
solution that effectively achieves load-balancing of VMs and bandwidth
utilization improvements with a similar form of transmission algorithm.

Basically, each VM has it's own vlan, so it always sends its traffic out
the same interface, unless that interface fails. Traffic gets split
between the interfaces, maintaining a consistent path, with failover still
available if an interface goes down.

Unlike bond_eth_hash(), this hash function is using the full source MAC
address instead of just the last byte, as there are so few components to
the hash, and in the no-vlan case, we would be returning just the last
byte of the source MAC as the hash value. It's entirely possible to have
two NICs in a bond with the same last byte of their MAC, but not the same
MAC, so this adjustment should guarantee distinct hashes in all cases.

This has been rudimetarily tested to provide similar results to the
proprietary solution it is aiming to replace. A patch for iproute2 is also
posted, to properly support the new mode there as well.

19d9a846d9 dt-binding: net: ti: k3-am654-cpsw-nuss: update bindings for am64x cpsw3g
Update DT binding for recently introduced TI K3 AM642x SoC [1] which
contains 3 port (2 external ports) CPSW3g module. The CPSW3g integrated
in MAIN domain and can be configured in multi port or switch modes.

The overall functionality and DT bindings are similar to other K3 CPSWxg
versions, so DT binding changes are minimal:
 - reword description
 - add new compatible 'ti,am642-cpsw-nuss'
 - allow 2 external ports child nodes
 - add missed 'assigned-clock' props

b3228c74e0 dt-binding: ti: am65x-cpts: add assigned-clock and power-domains props
The CPTS clock is usually a clk-mux which allows to select CPTS reference
clock by using 'assigned-clock-parents', 'assigned-clocks' DT properties.
Also depending on integration the power-domains has to be specified to
enable CPTS IP.

Hence add 'assigned-clock-parents', 'assigned-clocks' and 'power-domains'
properties to the CPTS DT bindings to avoid dtbs_check warnings:
 cpts@310d0000: 'assigned-clock-parents', 'assigned-clocks' do not match any of the regexes: 'pinctrl-[0-9]+'
 cpts@310d0000: 'power-domains' does not match any of the regexes: 'pinctrl-[0-9]+'

91c960b005 bpf: Rename BPF_XADD and prepare to encode other atomics in .imm
A subsequent patch will add additional atomic operations. These new
operations will use the same opcode field as the existing XADD, with
the immediate discriminating different operations.

In preparation, rename the instruction mode BPF_ATOMIC and start
calling the zero immediate BPF_ADD.

This is possible (doesn't break existing valid BPF progs) because the
immediate field is currently reserved MBZ and BPF_ADD is zero.

All uses are removed from the tree but the BPF_XADD definition is
kept around to avoid breaking builds for people including kernel
headers.

Merge tag 'net-5.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "We have a few fixes for long standing issues, in particular Eric's fix
  to not underestimate the skb sizes, and my fix for brokenness of
  register_netdevice() error path. They may uncover other bugs so we
  will keep an eye on them. Also included are Willem's fixes for
  kmap(_atomic).

  Looking at the "current release" fixes, it seems we are about one rc
  behind a normal cycle. We've previously seen an uptick of "people had
  run their test suites" / "humans actually tried to use new features"
  fixes between rc2 and rc3.

  Summary:

  Current release - regressions:

   - fix feature enforcement to allow NETIF_F_HW_TLS_TX if IP_CSUM &&

25537d71e2 net: Allow NETIF_F_HW_TLS_TX if IP_CSUM && IPV6_CSUM
Cited patch below blocked the TLS TX device offload unless HW_CSUM
is set. This broke devices that use IP_CSUM && IP6_CSUM.
Here we fix it.

Note that the single HW_TLS_TX feature flag indicates support for
both IPv4/6, hence it should still be disabled in case only one of
(IP_CSUM | IPV6_CSUM) is set.

b36b0fe96a x86/xen: Add xen_no_vector_callback option to test PCI INTX delivery
It's useful to be able to test non-vector event channel delivery, to make
sure Linux will work properly on older Xen which doesn't have it.

It's also useful for those working on Xen and Xen-compatible hypervisors,
because there are guest kernels still in active use which use PCI INTX
even when vector delivery is available.

6b5903f58d dt-bindings: net: dwmac-meson: use picoseconds for the RGMII RX delay
Amlogic Meson G12A, G12B and SM1 SoCs have a more advanced RGMII RX
delay register which allows picoseconds precision. Deprecate the old
"amlogic,rx-delay-ns" in favour of the generic "rx-internal-delay-ps"
property.

For older SoCs the only known supported values were 0ns and 2ns. The new
SoCs have support for RGMII RX delays between 0ps and 3000ps in 200ps
steps.

Don't carry over the description for the "rx-internal-delay-ps" property
and inherit that from ethernet-controller.yaml instead.
