c6d2754006 bonding: fix ad_actor_system option setting to default
[ Upstream commit 1c15b05baea71a5ff98235783e3e4ad227760876 ]

When 802.3ad bond mode is configured the ad_actor_system option is set to
"00:00:00:00:00:00". But when trying to set the all-zeroes MAC as actors'
system address it was failing with EINVAL.

An all-zeroes ethernet address is valid, only multicast addresses are not
valid values.

48e01e3881 ixgbe: Document how to enable NBASE-T support
[ Upstream commit 271225fd57c2f1e0b3f8826df51be6c634affefe ]

Commit a296d665ea ("ixgbe: Add ethtool support to enable 2.5 and 5.0
Gbps support") introduced suppression of the advertisement of NBASE-T
speeds by default, according to Todd Fujinaka to accommodate customers
with network switches which could not cope with advertised NBASE-T
speeds, as posted in the E1000-devel mailing list:

https://sourceforge.net/p/e1000/mailman/message/37106269/

However, the suppression was not documented at all, nor was how to
enable NBASE-T support.

Properly document the NBASE-T suppression and how to enable NBASE-T
support.

d689176e0e netfilter: ipvs: Fix reuse connection if RS weight is 0
[ Upstream commit c95c07836fa4c1767ed11d8eca0769c652760e32 ]

We are changing expire_nodest_conn to work even for reused connections when
conn_reuse_mode=0, just as what was done with commit dc7b3eb900 ("ipvs:
Fix reuse connection if real server is dead").

For controlled and persistent connections, the new connection will get the
needed real server depending on the rules in ip_vs_check_template().

Fixes: d752c36457 ("ipvs: allow rescheduling of new connections when port reuse is detected")

164294d09c tcp: disable TFO blackhole logic by default
[ Upstream commit 213ad73d06073b197a02476db3a4998e219ddb06 ]

Multiple complaints have been raised from the TFO users on the internet
stating that the TFO blackhole logic is too aggressive and gets falsely
triggered too often.
(e.g. https://blog.apnic.net/2021/07/05/tcp-fast-open-not-so-fast/)
Considering that most middleboxes no longer drop TFO packets, we decide
to disable the blackhole logic by setting
/proc/sys/net/ipv4/tcp_fastopen_blackhole_timeout_set to 0 by default.

Fixes: cf1ef3f071 ("net/tcp_fastopen: Disable active side TFO in certain scenarios")

8a4b8ea595 ANDROID: net: introduce ip_local_unbindable_ports sysctl
and associated inet_is_local_unbindable_port() helper function:
use it to make explicitly binding to an unbindable port return
-EPERM 'Operation not permitted'.

Autobind doesn't honour this new sysctl since:
  (a) you can simply set both if that's the behaviour you desire
  (b) there could be a use for preventing explicit while allowing auto
  (c) it's faster in the relatively critical path of doing port selection
      during connect() to only check one bitmap instead of both

Various ports may have special use cases which are not suitable for
use by general userspace applications. Currently, ports specified in
ip_local_reserved_ports sysctl will not be returned only in case of
automatic port assignment, but nothing prevents you from explicitly
binding to them - even from an entirely unprivileged process.

In certain cases it is desirable to prevent the host from assigning the
ports even in case of explicit binds, even from superuser processes.

Example use cases might be:
 - a port being stolen by the nic for remote serial console, remote
   power management or some other sort of debugging functionality
   (crash collection, gdb, direct access to some other microcontroller
   on the nic or motherboard, remote management of the nic itself).
 - a transparent proxy where packets are being redirected: in case
   a socket matches this connection, packets from this application
   would be incorrectly sent to one of the endpoints.

Initially I wanted to solve this problem via the simple one line:

static inline bool inet_port_requires_bind_service(struct net *net, unsigned short port) {
-       return port < net->ipv4.sysctl_ip_prot_sock;
+       return port < net->ipv4.sysctl_ip_prot_sock || inet_is_local_reserved_port(net, port);
}

However, this doesn't work for two reasons:
  (a) it changes userspace visible behaviour of the existing local
      reserved ports sysctl, and there appears to be enough documentation
      on the internet talking about setting it to make this a bad idea
  (b) it doesn't prevent privileged apps from using these ports,
      CAP_BIND_SERVICE is relatively likely to be available to, for example,
      a recursive DNS server so it can listed on port 53, which also needs
      to do src port randomization for outgoing queries due to security
      reasons (and it thus does manual port binding).

If we *know* that certain ports are simply unusable, then it's better
nothing even gets the opportunity to try to use them.  This way we at
least get a quick failure, instead of some sort of timeout (or possibly
even corruption of the data stream of the non-kernel based use case).

Test:
  vm:~# cat /proc/sys/net/ipv4/ip_local_unbindable_ports

  vm:~# python -c 'import socket; s = socket.socket(socket.AF_INET6, socket.SOCK_STREAM, 0); s.bind(("::", 3967))'
  vm:~# python -c 'import socket; s = socket.socket(socket.AF_INET6, socket.SOCK_DGRAM, 0); s.bind(("::", 3967))'
  vm:~# echo 3967 > /proc/sys/net/ipv4/ip_local_unbindable_ports
  vm:~# cat /proc/sys/net/ipv4/ip_local_unbindable_ports
  3967
  vm:~# python -c 'import socket; s = socket.socket(socket.AF_INET6, socket.SOCK_STREAM, 0); s.bind(("::", 3967))'
  socket.error: (1, 'Operation not permitted')
  vm:~# python -c 'import socket; s = socket.socket(socket.AF_INET6, socket.SOCK_DGRAM, 0); s.bind(("::", 3967))'
  socket.error: (1, 'Operation not permitted')

Pull networking fixes from Jakub Kicinski:
 "Networking fixes for 5.10-rc3, including fixes from wireless, can, and
  netfilter subtrees.

  Current merge window - bugs in new features:

   - can: isotp: isotp_rcv_cf(): enable RX timeout handling in
     listen-only mode

  Previous releases - regressions:

   - mac80211:
      - don't require VHT elements for HE on 2.4 GHz
      - fix regression where EAPOL frames were sent in plaintext

   - netfilter:
      - ipset: Update byte and packet counters regardless of whether
        they match

   - ip_tunnel: fix over-mtu packet send by allowing fragmenting even if
     inner packet has IP_DF (don't fragment) set in its header (when
     TUNNEL_DONT_FRAGMENT flag is not set on the tunnel dev)

   - net: fec: fix MDIO probing for some FEC hardware blocks

   - ip6_tunnel: set inner ipproto before ip6_tnl_encap to un-break gso
     support

   - sctp: Fix COMM_LOST/CANT_STR_ASSOC err reporting on big-endian
     platforms, sparse-related fix used the wrong integer size

  Previous releases - always broken:

   - netfilter: use actual socket sk rather than skb sk when routing
     harder

   - r8169: work around short packet hw bug on RTL8125 by padding frames

   - net: ethernet: ti: cpsw: disable PTPv1 hw timestamping
     advertisement, the hardware does not support it

   - chelsio/chtls: fix always leaking ctrl_skb and another leak caused
     by a race condition

   - fix drivers incorrectly writing into skbs on TX:
      - cadence: force nonlinear buffers to be cloned
      - gianfar: Account for Tx PTP timestamp in the skb headroom
      - gianfar: Replace skb_realloc_headroom with skb_cow_head for PTP

   - can: flexcan:
      - remove FLEXCAN_QUIRK_DISABLE_MECR quirk for LS1021A
      - add ECC initialization for VF610 and LX2160A
      - flexcan_remove(): disable wakeup completely

   - can: fix packet echo functionality:
      - peak_canfd: fix echo management when loopback is on
      - make sure skbs are not freed in IRQ context in case they need to
        be dropped
      - always clone the skbs to make sure they have a reference on the
        socket, and prevent it from disappearing
      - fix real payload length return value for RTR frames

   - can: j1939: return failure on bind if netdev is down, rather than
     waiting indefinitely

  Misc:

   - IPv6: reply ICMP error if the first fragment don't include all
     headers to improve compliance with RFC 8200"

include/linux/ethtool.h is included twice with kernel-doc,
both to document ethtool_pause_stats(). The first one is
at statistics.rst, and the second one at ethtool-netlink.rst.

Replace one of the references to use the name of the
function. The automarkup.py extension should create the
cross-references.

Solves this warning:

	../Documentation/networking/ethtool-netlink.rst: WARNING: Duplicate C declaration, also defined in 'networking/statistics'.
	Declaration is 'ethtool_pause_stats'.

Pull networking fixes from Jakub Kicinski:
 "Cross-tree/merge window issues:

   - rtl8150: don't incorrectly assign random MAC addresses; fix late in
     the 5.9 cycle started depending on a return code from a function
     which changed with the 5.10 PR from the usb subsystem

  Current release regressions:

   - Revert "virtio-net: ethtool configurable RXCSUM", it was causing
     crashes at probe when control vq was not negotiated/available

  Previous release regressions:

   - ixgbe: fix probing of multi-port 10 Gigabit Intel NICs with an MDIO
     bus, only first device would be probed correctly

   - nexthop: Fix performance regression in nexthop deletion by
     effectively switching from recently added synchronize_rcu() to
     synchronize_rcu_expedited()

   - netsec: ignore 'phy-mode' device property on ACPI systems; the
     property is not populated correctly by the firmware, but firmware
     configures the PHY so just keep boot settings

  Previous releases - always broken:

   - tcp: fix to update snd_wl1 in bulk receiver fast path, addressing
     bulk transfers getting "stuck"

   - icmp: randomize the global rate limiter to prevent attackers from
     getting useful signal

   - r8169: fix operation under forced interrupt threading, make the
     driver always use hard irqs, even on RT, given the handler is light
     and only wants to schedule napi (and do so through a _irqoff()
     variant, preferably)

   - bpf: Enforce pointer id generation for all may-be-null register
     type to avoid pointers erroneously getting marked as null-checked

   - tipc: re-configure queue limit for broadcast link

   - net/sched: act_tunnel_key: fix OOB write in case of IPv6 ERSPAN
     tunnels

   - fix various issues in chelsio inline tls driver

  Misc:

   - bpf: improve just-added bpf_redirect_neigh() helper api to support
     supplying nexthop by the caller - in case BPF program has already
     done a lookup we can avoid doing another one

   - remove unnecessary break statements

   - make MCTCP not select IPV6, but rather depend on it"

  This includes:

   - ReST fixes

   - Updates at the build system in order to support newer versions of

  After this series, the number of html build warnings should reduce

  As agreed with Jon, I should be sending you a late pull request by the

  as there are a number of warning fixes that depends on pull requests
  that should be happening along the merge window.

  The end goal is to have a clean htmldocs build on Kernel 5.10.

  PS. It should be noticed that Sphinx 3.0 is not currently supported,

9ff9b0d392 Merge tag 'net-next-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski:

 - Add redirect_neigh() BPF packet redirect helper, allowing to limit
   stack traversal in common container configs and improving TCP
   back-pressure.

   Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain.

 - Expand netlink policy support and improve policy export to user
   space. (Ge)netlink core performs request validation according to
   declared policies. Expand the expressiveness of those policies
   (min/max length and bitmasks). Allow dumping policies for particular
   commands. This is used for feature discovery by user space (instead
   of kernel version parsing or trial and error).

 - Support IGMPv3/MLDv2 multicast listener discovery protocols in
   bridge.

 - Allow more than 255 IPv4 multicast interfaces.

 - Add support for Type of Service (ToS) reflection in SYN/SYN-ACK
   packets of TCPv6.

 - In Multi-patch TCP (MPTCP) support concurrent transmission of data on
   multiple subflows in a load balancing scenario. Enhance advertising
   addresses via the RM_ADDR/ADD_ADDR options.

 - Support SMC-Dv2 version of SMC, which enables multi-subnet
   deployments.

 - Allow more calls to same peer in RxRPC.

 - Support two new Controller Area Network (CAN) protocols - CAN-FD and
   ISO 15765-2:2016.

 - Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit
   kernel problem.

 - Add TC actions for implementing MPLS L2 VPNs.

 - Improve nexthop code - e.g. handle various corner cases when nexthop
   objects are removed from groups better, skip unnecessary
   notifications and make it easier to offload nexthops into HW by
   converting to a blocking notifier.

 - Support adding and consuming TCP header options by BPF programs,
   opening the doors for easy experimental and deployment-specific TCP
   option use.

 - Reorganize TCP congestion control (CC) initialization to simplify
   life of TCP CC implemented in BPF.

 - Add support for shipping BPF programs with the kernel and loading
   them early on boot via the User Mode Driver mechanism, hence reusing
   all the user space infra we have.

 - Support sleepable BPF programs, initially targeting LSM and tracing.

 - Add bpf_d_path() helper for returning full path for given 'struct
   path'.

 - Make bpf_tail_call compatible with bpf-to-bpf calls.

 - Allow BPF programs to call map_update_elem on sockmaps.

 - Add BPF Type Format (BTF) support for type and enum discovery, as
   well as support for using BTF within the kernel itself (current use
   is for pretty printing structures).

 - Support listing and getting information about bpf_links via the bpf
   syscall.

 - Enhance kernel interfaces around NIC firmware update. Allow
   specifying overwrite mask to control if settings etc. are reset
   during update; report expected max time operation may take to users;
   support firmware activation without machine reboot incl. limits of
   how much impact reset may have (e.g. dropping link or not).

 - Extend ethtool configuration interface to report IEEE-standard
   counters, to limit the need for per-vendor logic in user space.

 - Adopt or extend devlink use for debug, monitoring, fw update in many
   drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx,
   dpaa2-eth).

 - In mlxsw expose critical and emergency SFP module temperature alarms.
   Refactor port buffer handling to make the defaults more suitable and
   support setting these values explicitly via the DCBNL interface.

 - Add XDP support for Intel's igb driver.

 - Support offloading TC flower classification and filtering rules to
   mscc_ocelot switches.

 - Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as
   fixed interval period pulse generator and one-step timestamping in
   dpaa-eth.

 - Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3)
   offload.

 - Add Lynx PHY/PCS MDIO module, and convert various drivers which have
   this HW to use it. Convert mvpp2 to split PCS.

 - Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as
   7-port Mediatek MT7531 IP.

 - Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver,
   and wcn3680 support in wcn36xx.

 - Improve performance for packets which don't require much offloads on
   recent Mellanox NICs by 20% by making multiple packets share a
   descriptor entry.

 - Move chelsio inline crypto drivers (for TLS and IPsec) from the
   crypto subtree to drivers/net. Move MDIO drivers out of the phy
   directory.

 - Clean up a lot of W=1 warnings, reportedly the actively developed
   subsections of networking drivers should now build W=1 warning free.

 - Make sure drivers don't use in_interrupt() to dynamically adapt their
   code. Convert tasklets to use new tasklet_setup API (sadly this
   conversion is not yet complete).

6575aeab72 Documentation: better locations for sysfs-pci, sysfs-tagging
sysfs-pci and sysfs-tagging were mis-filed: their locations within
Documentation/ implied that they were related to file systems. Actually,
each topic is about a very specific *use* of sysfs, and sysfs *happens*
to be a (virtual) filesystem, so this is not really the right place.

It's jarring to be reading about filesystems in general and then come
across these specific details about PCI, and tagging...and then back to
general filesystems again.

Move sysfs-pci to PCI, and move sysfs-tagging to networking. (Thanks to
Jonathan Corbet for coming up with the final locations.)

f2bf88c4af net: caif: Remove unused caif SPI driver
While chasing in_interrupt() (ab)use in drivers it turned out that the
caif_spi driver has never been in use since the driver was merged 10 years
ago. There never was any matching code which provides a platform device.

The driver has not seen any update (asided of treewide changes and
cleanups) since 8 years and the maintainers vanished from the planet.

So analysing the potential contexts and the (in)correctness of
in_interrupt() usage is just a pointless exercise.

However, it may sometimes be useful to allow overwriting these fields
when performing a flash update. Some examples include, 1) customizing
the initial device config on first programming, such as overwriting
default device identifying information, or 2) reverting a device
configuration to known good state provided in the new firmware image, or
3) in case it is suspected that current firmware logic for managing the
preservation of fields during an update is broken.

Although some devices are able to completely separate these types of
settings and fields into separate components, this is not true for all
hardware.

To support controlling this behavior, a new
DEVLINK_ATTR_FLASH_UPDATE_OVERWRITE_MASK is defined. This is an
nla_bitfield32 which will define what subset of fields in a component
should be overwritten during an update.

If no bits are specified, or of the overwrite mask is not provided, then
an update should not overwrite anything, and should maintain the
settings and identifiers as they are in the previous image.

If the overwrite mask has the DEVLINK_FLASH_OVERWRITE_SETTINGS bit set,
then the device should be configured to overwrite any of the settings in
the requested component with settings found in the provided image.

Similarly, if the DEVLINK_FLASH_OVERWRITE_IDENTIFIERS bit is set, the
device should be configured to overwrite any device identifiers in the
requested component with the identifiers from the image.

Multiple overwrite modes may be combined to indicate that a combination
of the set of fields that should be overwritten.

Drivers which support the new overwrite mask must set the
DEVLINK_SUPPORT_FLASH_UPDATE_OVERWRITE_MASK in the
supported_flash_update_params field of their devlink_ops.

3ab0a7a0c3 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Two minor conflicts:

1) net/ipv4/route.c, adding a new local variable while
   moving another local variable and removing it's
   initial assignment.

2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes.
   One pretty prints the port mode differently, whilst another
   changes the driver to try and obtain the port mode from
   the port node rather than the switch node.

c452f37597 net: ena: update ena documentation
The PCI vendor IDs in the documentation inaccurately describe the ENA
devices. For example, the 1d0f:ec20 can have LLQ support. The driver
loads in LLQ mode by default, and a message is printed to the kernel
ring if the mode isn't supported by the device, so the device table
isn't needed.

Also, LLQ can support various entry sizes, so the documentation is
updated to reflect that.

Interrupt moderation description is also updated to be more accurate.

0deca83ff1 net: ena: Change RSS related macros and variables names
The formal name changes to "ENA_ADMIN_RSS_INDIRECTION_TABLE_CONFIG".
Indirection is the ability to reference "something" using "something else"
instead of the value itself.
Indirection table, as the name implies, is the ability to reference
CPU/Queue value using hash-to-CPU table instead of CPU/Queue itself.

This patch renames the variable keys_num, which describes the number of
words in the RSS hash key, to key_parts which makes its purpose clearer
in RSS context.

19a83d36f9 ethtool: add and use message type for tunnel info reply
Tunnel offload info code uses ETHTOOL_MSG_TUNNEL_INFO_GET message type (cmd
field in genetlink header) for replies to tunnel info netlink request, i.e.
the same value as the request have. This is a problem because we are using
two separate enums for userspace to kernel and kernel to userspace message
types so that this ETHTOOL_MSG_TUNNEL_INFO_GET (28) collides with
ETHTOOL_MSG_CABLE_TEST_TDR_NTF which is what message type 28 means for
kernel to userspace messages.

As the tunnel info request reached mainline in 5.9 merge window, we should
still be able to fix the reply message type without breaking backward
compatibility.

  - A license for the device firmware

    This license is pointless in the context of the kernel as the firmware
    is not distributed as part of the kernel.

    LICENSE.qla2xxx contained exactly the same firmware license which was
    removed with commit bc3f957c06 ("[SCSI] qla2xxx: Update
    LICENSE.qla2xxx.").

    The firmware license is there due to the fact that the out of tree
    driver tarball which was available from the qlogic website contained
    the firmware binary. The firmware license in the qla3xxx license file
    got probably forgotten when the other qlogic license files were
    updated.

Remove the notices and add the SPDX license identifier GPL-2.0-or-later to
the source files.

Finally remove the now redundant LICENSE.qla3xxx file.
