Devlink param value attribute is not defined since devlink is handling
the value validating and parsing internally, this allows us to implement
multi attribute values without breaking any policies.
Devlink param multi-attribute values are considered to be dynamically
sized arrays of u64 values, by introducing a new devlink param type
DEVLINK_PARAM_TYPE_U64_ARRAY, driver and user space can set a variable
count of u64 values into the DEVLINK_ATTR_PARAM_VALUE_DATA attribute.
Implement get/set parsing and add to the internal value structure passed
to drivers.
This is useful for devices that need to configure a list of values for
a specific configuration.
example:
$ devlink dev param show pci/... name multi-value-param
name multi-value-param type driver-specific
values:
cmode permanent value: 0,1,2,3,4,5,6,7
$ devlink dev param set pci/... name multi-value-param \
value 4,5,6,7,0,1,2,3 cmode permanent

1) Replace the open-coded manual cleanup in xfrm_add_policy() error
path with xfrm_policy_destroy() for consistency with
xfrm_policy_construct().
From Deepanshu Kartikey.
2) Limit XFRMA_TFCPAD to a sensible maximum (max IP length, 64k) since
u32 is excessive for traffic flow confidentiality padding.
From David Ahern.
3) Add a new netlink message XFRM_MSG_MIGRATE_STATE that
allows migrating individual IPsec SAs independently of
their policies. The existing XFRM_MSG_MIGRATE is tightly coupled
to policy+SA migration, lacks SPI for unique SA identification,
and cannot express reqid changes or migrate Transport mode
selectors. The new interface identifies the SA via SPI and mark,
supports reqid changes, address family changes, encap removal,
and uses an atomic create+install flow under x->lock to prevent
SN/IV reuse during AEAD SA migration.
From Antony Antony.

Add vsock_pending_to_accept() to move a socket directly from the
pending list to the accept queue in a single operation, avoiding
the sock_put/sock_hold dance and the sk_acceptq_removed()/
sk_acceptq_added() pair that would otherwise be needed when
calling vsock_remove_pending() followed by vsock_enqueue_accept().
Use it in vmci_transport_recv_connecting_server() where a completed
handshake transitions the socket from pending to accept queue.

The main purpose of this cmd is to be able to associate a
non-psp-capable device (e.g. veth or netkit) with a psp device.
One use case is if we create a pair of veth/netkit, and assign 1 end
inside a netns, while leaving the other end within the default netns,
with a real PSP device, e.g. netdevsim or a physical PSP-capable NIC.
With this command, we could associate the veth/netkit inside the netns
with PSP device, so the virtual device could act as PSP-capable device
to initiate PSP connections, and performs PSP encryption/decryption on
the real PSP device.

With TCP-timestamps (padded) taking 12 bytes and ADD_ADDR IPv6 + port
taking 30 bytes, the 40-byte limit for the TCP options is reached. In
this case, it is then not possible to send the address signal.
The idea is to let MPTCP dropping the TCP-timestamps option for some
specific packets, to be able to send some specific pure ACK carrying >28
bytes of MPTCP options, like with this specific ADD_ADDR. A new
parameter is passed from tcp_established_options to the MPTCP side to
indicate if the TCP TS option is used, and if it should be dropped. The
next commit implements the part on MPTCP side, but split into two
patches to help TCP maintainers to identify the modifications on TCP
side. This feature will be controlled by a new add_addr_v6_port_drop_ts
MPTCP sysctl knob.
It is important to keep in mind that dropping the TCP timestamps option
for one packet of the connection could eventually disrupt some
middleboxes: even if it should be unlikely, they could drop the packet
or even block the connection. That's why this new feature will be
controlled by a sysctl knob.
Note that it would be technically possible to squeeze both options into
the header if the ADD_ADDR is first written, and then the TCP timestamps
without the NOPs preceding it. But this means more modifications on TCP
side, plus some middleboxes could still be disrupted by that.
In this implementation, an unused bit is used in mptcp_out_options
structure to avoid passing an address to a local variable. Reading and
setting it needs CONFIG_MPTCP, so the whole block now has this #if
condition: mptcp_established_options() is then no longer used without
CONFIG_MPTCP.
About alternatives, instead of passing a new boolean (has_ts), another
option would be to pass the whole option structure (opts), but
'struct tcp_out_options' is currently defined in tcp_output.c, and it
would need to be exported. Plus that means the removal of the TCP TS
option would be done on the MPTCP side, and not here on the TCP side.
It feels clearer to remove other TCP options from the TCP side, than
hiding that from the MPTCP side.
Yet an other alternative would be to pass the size already taken by the
other TCP options, and have a way to drop them all when needed. But this
feels better to target only the timestamps option where dropping it
should be safe, even if it is currently the only option that would be
set before MPTCP, when MPTCP is used.

Fix it by having chan->conn hold a reference to l2cap_conn (via
l2cap_conn_get) when the channel is added to the connection, and
releasing it in the channel destructor. This ensures the l2cap_conn
remains alive as long as the channel exists.
A new FLAG_DEL channel flag is introduced to indicate that the channel
has been deleted from its connection. l2cap_chan_del() atomically sets
this flag using test_and_set_bit() instead of setting chan->conn to
NULL. All asynchronous workers (l2cap_chan_timeout, l2cap_ack_timeout,
l2cap_monitor_timeout, l2cap_retrans_timeout) and l2cap_chan_send()
check FLAG_DEL to determine whether the channel has been torn down,
rather than testing chan->conn for NULL.

NAT helpers such as nf_nat_h323 store a raw pointer to module text in
exp->expectfn (e.g. ip_nat_q931_expect). nf_ct_helper_expectfn_unregister()
only unlinks the callback descriptor and never walks the expectation table,
so an expectation pending at module removal survives with a dangling
exp->expectfn into freed module text.
When the expected connection arrives, init_conntrack() invokes
exp->expectfn(), now a stale pointer into the unloaded module. Reproduced
on a KASAN build by loading the H.323 helpers, creating a Q.931
expectation, unloading nf_nat_h323, then connecting to the expected port:

Reaching the dangling state requires CAP_SYS_MODULE in the initial user
namespace to remove a NAT helper that still has live expectations, so this
is a robustness fix; leaving an expectation pointing at freed text is wrong
regardless.
Add nf_ct_helper_expectfn_destroy(), which walks the expectation table and
drops every expectation whose ->expectfn matches the descriptor being torn
down. Call it from each NAT helper's exit path after the existing RCU grace
period, so no expectation outlives the code it points at and no extra
synchronize_rcu() is introduced. With the fix, the same reproducer runs to
completion without the Oops.

When an 802.3ad (LACP) bonding interface has no slaves in the
collecting/distributing state, the bonding master still reports
carrier as up as long as at least 'min_links' slaves have carrier.
In this situation, only one slave is effectively used for TX/RX,
while traffic received on other slaves is dropped. Upper-layer
daemons therefore consider the interface operational, even though
traffic may be blackholed if the lack of LACP negotiation means
the partner is not ready to deal with traffic.
Introduce a configuration knob to control this behavior. It allows
the bonding master to assert carrier only when at least 'min_links'
slaves are in Collecting_Distributing state.
The default mode preserves the existing behavior. This patch only
introduces the knob; its behavior is implemented in the subsequent
commit.

skb_is_err_queue() treats PACKET_OUTGOING as the sole marker for an skb
from sk_error_queue. That assumption is not true for AF_PACKET sockets:
outgoing packet taps are also delivered to packet sockets with
skb->pkt_type == PACKET_OUTGOING, but their skb->cb is owned by AF_PACKET
instead of struct sock_exterr_skb.
If such an skb is received with timestamping enabled, the generic
timestamp cmsg path can read AF_PACKET control-buffer state as
sock_exterr_skb::opt_stats. With SO_RXQ_OVFL enabled, the packet drop
counter overlaps opt_stats. An odd drop count makes the path emit
SCM_TIMESTAMPING_OPT_STATS with skb->len and skb->data. For non-linear
skbs this copies past the linear head and can trigger hardened usercopy or
disclose adjacent heap contents.
Keep skb_is_err_queue() local to net/socket.c, but make it verify that
the PACKET_OUTGOING marker is paired with the sock_rmem_free destructor
installed by sock_queue_err_skb(). AF_PACKET receive skbs use normal
receive ownership and no longer pass as error-queue skbs, while legitimate
sk_error_queue entries keep the PACKET_OUTGOING marker and sock_rmem_free
ownership.

mana_query_link_cfg() sends an HWC command to firmware on every call,
but the link speed and QoS values it returns only change when the
driver explicitly calls mana_set_bw_clamp(). This function is called
not only by userspace via ethtool get_link_ksettings, but also
periodically by hv_netvsc through netvsc_get_link_ksettings and by
the sysfs speed_show attribute via dev_attr_show, resulting in
unnecessary HWC traffic every few minutes.
Add a link_cfg_error field to mana_port_context to cache the query
result. The field uses three states: 1 (not yet queried, initial
value set during mana_probe_port), 0 (success, speed/max_speed are
valid), or a negative errno for permanent errors like -EOPNOTSUPP
when the hardware does not support the command. Transient errors and
qos_unconfigured responses are not cached so that subsequent calls
will retry.
MANA is ops-locked because it implements net_shaper_ops, so the core

entry points. Reuse that lock to serialize mana_query_link_cfg() and
mana_set_bw_clamp(). This prevents a concurrent mana_set_bw_clamp()
from racing with an in-flight query and publishing stale pre-clamp
speed/max_speed.
Invalidate the cache inside mana_set_bw_clamp() on success, so all
current and future callers that change the link configuration
automatically trigger a fresh query on the next mana_query_link_cfg()
call. Also reset link_cfg_error during resume in mana_probe() under
netdev_lock(), so that any query already in flight cannot later
store 0 and silently overwrite the post-resume invalidation.

Use the GIC functions to allocate interrupt contexts for RDMA EQs. These
interrupt contexts may be shared with Ethernet EQs when MSI-X vectors
are limited.
The driver now supports allocating dedicated MSI-X for each EQ. Indicate
this capability through driver capability bits. The RDMA EQs pass
use_msi_bitmap=false to share MSI-X vectors with Ethernet, while the
capability flag advertises that the driver supports per-vPort EQ
separation when hardware has sufficient vectors.
Populate eq.irq on all RDMA EQs for consistency with the Ethernet path.
Also relocate the GDMA_DRV_CAP_FLAG_1_HW_VPORT_LINK_AWARE define to its
numeric BIT(6) position among the other capability flags.

When querying the device, adjust the max number of queues to allow
dedicated MSI-X vectors for each vPort. The per-vPort queue count is
clamped towards MANA_DEF_NUM_QUEUES but will not exceed the hardware
maximum reported by the device.
MSI-X sharing among vPorts is enabled when there are not enough MSI-X
vectors for dedicated allocation, or when the platform does not support
dynamic MSI-X allocation (in which case all vectors are pre-allocated
at probe time and sharing is always used). The msi_sharing flag is
reset at the top of mana_gd_query_max_resources() so it is recomputed
from current hardware state on each probe or resume cycle.
Clamp apc->max_queues to gc->max_num_queues_vport in mana_init_port()
so that on resume, if max_num_queues_vport has decreased due to fewer
MSI-X vectors, num_queues is reduced accordingly before EQ allocation.
A device reporting zero ports now results in a fatal probe error since
the per-vPort MSI-X math requires at least one port.
Rename mana_query_device_cfg() to mana_gd_query_device_cfg() as it is
used at GDMA device probe time for querying device capabilities.

To prepare for assigning vPorts to dedicated MSI-X vectors, remove EQ
sharing among the vPorts and create dedicated EQs for each vPort.
Move the EQ definition from struct mana_context to struct mana_port_context
and update related support functions. Export mana_create_eq() and
mana_destroy_eq() for use by the MANA RDMA driver.
RSS QPs now take a vport reference via pd->vport_use_count to ensure
EQs outlive all QP consumers. The vport must already be configured by
a raw QP before an RSS QP can be created. EQs are only destroyed when
the last QP (raw or RSS) on the PD releases its reference.
Restrict each vport to a single RSS QP. The hardware only supports one
steering configuration (indirection table / hash key) per vport, and
mana_disable_vport_rx() on QP destroy disables RX globally for the
vport. Previously, creating a second RSS QP would silently overwrite
the first QP's steering config and destroy would blackhole all traffic.
This is now explicitly rejected with -EBUSY. Existing applications
(DPDK being the primary RDMA consumer) always create one RSS QP per
vport, so no real-world flows are affected.
Reject cross-port PD sharing for both raw and RSS QPs. Since EQs and
vport configuration are per-port, a PD is bound to the port used by
its first raw QP. Subsequent QPs on the same PD must use the same
port or the creation fails with -EINVAL. Previously this was silently
broken: with shared EQs it appeared to work, but with per-vPort EQs
a cross-port PD would cause wrong-port EQ teardown and corruption.
DPDK creates one PD per port so no existing flows are affected.
Serialize mana_set_channels() and the async per-port queue reset
handler against RDMA vport configuration to prevent RDMA from claiming
the vport during the detach/attach window. A channel_changing flag is
set under apc->vport_mutex before detach and checked by
mana_cfg_vport() when called from the RDMA path, blocking RDMA from
grabbing the vport during the entire window. When the port is down
and RDMA already holds the vport, the channel change is rejected with
-EBUSY.

Each record release via tls_strp_msg_done() triggered
tls_strp_check_rcv(), which called tls_rx_msg_ready() and
fired saved_data_ready(). During a multi-record receive, the
first N-1 wakeups are pure overhead: the caller is already
running and will pick up subsequent records on the next loop
iteration. The recvmsg and splice_read paths share this waste.
Suppress per-record notifications and emit a single one on
reader exit. tls_rx_rec_done() releases the current record
and parses the next without announcing; tls_strp_check_rcv()
gains a bool announce parameter so callers can request the
quiet form. tls_rx_reader_release() fires the deferred
announce on exit through tls_rx_msg_maybe_announce(), an
idempotent helper that calls saved_data_ready() only when a
record is parsed and has not yet been announced.
To keep the final notification idempotent against records that
the BH or the worker has already announced, tls_strparser gains
a msg_announced bit. tls_rx_msg_maybe_announce() sets the bit
when firing saved_data_ready(); the bit is cleared whenever
the parsed record is wiped, by tls_strp_msg_consume() on
consumption or by tls_strp_msg_load() when the lower socket
loses bytes from under the parse. A second call for the same
parsed record -- as when recvmsg() satisfies the request from
ctx->rx_list without touching the strparser -- becomes a
no-op.
With no remaining callers, tls_strp_msg_done() is removed.

This patch adds a new ->ct_refcnt field to struct nf_conntrack_helper

packet path refcount which ensures that struct nf_conntrack_helper

elsewhere, with a conntrack that refers to this helper.
For simplicity, this leaves a single refcount for helper objects in
place, remove the existing refcount for control plane that ensures that
the helper does not go away if it is used by ruleset.
On helper removal, the help callback is set to NULL to disable it from
packet path and, after rcu grace period, existing expectations are

Add a refcount for struct nf_ct_timeout which is used by ct extension to
set the custom ct timeout policy, this tells us that the ct timeout is
being used by a conntrack entry. When the last conntrack entry drops the
refcount on the ct timeout, the ct timeout is released.
Remove the refcount for control plane which controls if the ruleset
refers to the timeout policy. After this update, it is possible to
remove the ct timeout policy from nfnetlink_cttimeout immediately.
This is for simplicity not to handle two refcounts on a single object.
Remove nf_queue_nf_hook_drop(): a packet sitting in nfqueue will just
hold a reference to the nf_ct_timeout object until packet is reinjected,
since this is part of the ct extension, this will be released by the
time the conntrack is freed.
nf_ct_untimeout() is still called to clean up in a best effort basis:
the ct timeout on existing entries gets removed when the ct timeout goes
away, but as long as the iptables ruleset still refers to the ct timeout
through a template, new conntracks may keep attaching it and extend its
lifetime until the rule is removed.
nf_ct_untimeout() is not called anymore from module removal path, this
is unlikely to find timeouts give module refcount is bumped, and the new
refcount already tracks the ct timeout policy use so it is released when
unused.

The existing helper check for either ops lock or rtnl_lock,
which is the locking behavior of netdev_lock_ops_compat().
The reason for naming divergence is likely that
netdev_ops_assert_locked() predated the _compat() helpers.
