In many deployments, we want the option to not learn a neighbor from
garp if the src ip is not in the same subnet as an address configured
on the interface that received the garp message. net.ipv4.arp_accept
sysctl is currently used to control creation of a neigh from a
received garp packet. This patch adds a new option '2' to
net.ipv4.arp_accept which extends option '1' by including the subnet
check.

1) Support 802.1ad for bridge offloads
Vlad Buslov Says:
=================
Current mlx5 bridge VLAN offload implementation only supports 802.1Q VLAN
Ethernet protocol. That protocol type is assumed by default and
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL notification is ignored.
In order to support dynamically setting VLAN protocol handle
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL notification by flushing FDB and
re-creating VLAN modify header actions with a new protocol. Implement support
for 802.1ad protocol by saving the current VLAN protocol to per-bridge variable
and re-create the necessary flow groups according to its current value (either
use cvlan or svlan flow fields).

"Including fixes from netfilter, bpf and wireless.
Still no major regressions, the release continues to be calm. An
uptick of fixes this time around due to trivial data race fixes and

There has been a few driver fixes (particularly a few fixes for false

Use software VHCA id when it's supported by the firmware.
A unique id is allocated upon mlx5_mdev_init() and freed upon
mlx5_mdev_uninit(), as such it stays the same during the full life cycle
of the device including upon health recovery if occurred.
The conjunction of sw_vhca_id with sw_owner_id will be a global unique
id per function which uses mlx5_core.
The sw_vhca_id is set upon init_hca command and is used to specify the
VHCA that the NIC vport is affiliated with.
This functionality is needed upon migration of VM which is MPV based.
(i.e. multi port device).

This pull request contains the fix for an old and subtle bug in the
migration path. css_sets are used to track tasks and migrations are tasks
moving from a group of css_sets to another group of css_sets. The migration
path pins all source and destination css_sets in the prep stage.
Unfortunately, it was overloading the same list_head entry to track sources
and destinations, which got confused for migrations which are partially
identity leading to use-after-frees. Fixed by using dedicated list_heads for
tracking sources and destinations.

As part of the flows invoked by mlx5_devlink_eswitch_mode_set() get to
mlx5_rescan_drivers_locked() which can call mlx5e_probe()/mlx5e_remove
and register/unregister mlx5e driver ports accordingly. This can lead to
deadlock once mlx5_devlink_eswitch_mode_set() will use devlink lock.
Use devl_port_register/unregister() instead of
devlink_port_register/unregister() and add devlink instance locks in the
driver paths to this function to have it locked while calling devl_ API
function.
If remove or probe were called by module init or module cleanup flows,
need to lock devlink just before calling devl_port_register(), otherwise
it is called by attach/detach or register/unregister flow and we can
have the flow locked. Added flag to distinguish between these cases.
This will be used by the downstream patch to invoke
mlx5_devlink_eswitch_mode_set() with devlink locked.

If we set XFRM security policy by calling setsockopt with option
IPV6_XFRM_POLICY, the policy will be stored in 'sock_policy' in 'sock'
struct. However tcp_v6_send_response doesn't look up dst_entry with the
actual socket but looks up with tcp control socket. This may cause a
problem that a RST packet is sent without ESP encryption & peer's TCP
socket can't receive it.
This patch will make the function look up dest_entry with actual socket,
if the socket has XFRM policy(sock_policy), so that the TCP response
packet via this function can be encrypted, & aligned on the encrypted
TCP socket.
Tested: We encountered this problem when a TCP socket which is encrypted
in ESP transport mode encryption, receives challenge ACK at SYN_SENT
state. After receiving challenge ACK, TCP needs to send RST to
establish the socket at next SYN try. But the RST was not encrypted &
peer TCP socket still remains on ESTABLISHED state.
So we verified this with test step as below.
[Test step]
1. Making a TCP state mismatch between client(IDLE) & server(ESTABLISHED).
2. Client tries a new connection on the same TCP ports(src & dst).
3. Server will return challenge ACK instead of SYN,ACK.
4. Client will send RST to server to clear the SOCKET.
5. Client will retransmit SYN to server on the same TCP ports.
[Expected result]
The TCP connection should be established.

Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) refcount_inc_not_zero() is not semantically equivalent to
atomic_int_not_zero(), from Florian Westphal. My understanding was
that refcount_*() API provides a wrapper to easier debugging of
reference count leaks, however, there are semantic differences
between these two APIs, where refcount_inc_not_zero() needs a barrier.
Reason for this subtle difference to me is unknown.
2) packet logging is not correct for ARP and IP packets, from the
ARP family and netdev/egress respectively. Use skb_network_offset()
to reach the headers accordingly.
3) set element extension length have been growing over time, replace
a BUG_ON by EINVAL which might be triggerable from userspace.

commit dd374f84ba ("wifi: nl80211: expose link ID for associated
BSSes") used a top-level attribute to send link ID of the associated
BSS in the nested attribute NL80211_ATTR_BSS. But since NL80211_ATTR_BSS
is a nested attribute of the attributes defined in enum nl80211_bss,
define a new attribute in enum nl80211_bss and use it for sending the
link ID of the BSS.

Signed-off-by: Jakub Kicinski <kuba@kernel.org>
sk_skb_cb lives within skb->cb[]. skb->cb[] straddles
2 cache lines, each containing 24B of data.
The first cache line does not contain much interesting
information for users of strparser, so pad things a little.
Previously strp_msg->full_len would live in the first cache
line and strp_msg->offset in the second.
We need to reorder the 8 byte temp_reg with struct tls_msg
to prevent a 4B hole which would push the struct over 48B.

Pull io_uring tweak from Jens Axboe:
"Just a minor tweak to an addition made in this release cycle: padding
a 32-bit value that's in a 64-bit union to avoid any potential
funkiness from that"
* tag 'io_uring-5.19-2022-07-08' of git://git.kernel.dk/linux-block:
io_uring: explicit sqe padding for ioctl commands
fbcon now prevents switching to screen resolutions which are smaller
than the font size, and prevents enabling a font which is bigger than
the current screen resolution. This fixes vmalloc-out-of-bounds accesses
found by KASAN.
Guiling Deng fixed a bug where the centered fbdev logo wasn't displayed
correctly if the screen size matched the logo size.
Hsin-Yi Wang provided a patch to include errno.h to fix build when
CONFIG_OF isn't enabled.

While reading .sysctl_mem, it can be changed concurrently.
So, we need to add READ_ONCE() to avoid data-races.
