- All 6GHz channels are scanned passively: 58 channels.
- The scan is fragmented with the following parameters: 3 fragments,
  95 TUs suspend time, 44 TUs maximal out of channel time.

The above would result with scan time of more than 24 seconds. Thus,
set the timeout to 30 seconds.

mptcp: enforce HoL-blocking estimation

The MPTCP packet scheduler has sub-optimal behavior with asymmetric
subflows: if the faster subflow-level cwin is closed, the packet
scheduler can enqueue "too much" data on a slower subflow.

When all the data on the faster subflow is acked, if the mptcp-level
cwin is closed, and link utilization becomes suboptimal.

The solution is implementing blest-like[1] HoL-blocking estimation,
transmitting only on the subflow with the shorter estimated time to
flush the queued memory. If such subflows cwin is closed, we wait
even if other subflows are available.

This is quite simpler than the original blest implementation, as we
leverage the pacing rate provided by the TCP socket. To get a more
accurate estimation for the subflow linger-time, we maintain a
per-subflow weighted average of such info.

Additionally drop magic numbers usage in favor of newly defined
macros and use more meaningful names for status variable.

Brett Creeley [Tue, 30 Nov 2021 00:16:02 +0000 (16:16 -0800)]
iavf: Add support for VIRTCHNL_VF_OFFLOAD_VLAN_V2 hotpath

The new VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability added support that allows
the PF to set the location of the Tx and Rx VLAN tag for insertion and
stripping offloads. In order to support this functionality a few changes
are needed.

1. Add a new method to cache the VLAN tag location based on negotiated
   capabilities for the Tx and Rx ring flags. This needs to be called in
   the initialization and reset paths.

2. Refactor the transmit hotpath to account for the new Tx ring flags.
   When IAVF_TXR_FLAGS_VLAN_LOC_L2TAG2 is set, then the driver needs to
   insert the VLAN tag in the L2TAG2 field of the transmit descriptor.
   When the IAVF_TXRX_FLAGS_VLAN_LOC_L2TAG1 is set, then the driver needs
   to use the l2tag1 field of the data descriptor (same behavior as
   before).

3. Refactor the iavf_tx_prepare_vlan_flags() function to simplify
   transmit hardware VLAN offload functionality by only depending on the
   skb_vlan_tag_present() function. This can be done because the OS
   won't request transmit offload for a VLAN unless the driver told the
   OS it's supported and enabled.

4. Refactor the receive hotpath to account for the new Rx ring flags and
   VLAN ethertypes. This requires checking the Rx ring flags and
   descriptor status bits to determine the location of the VLAN tag.
   Also, since only a single ethertype can be supported at a time, check
   the enabled netdev features before specifying a VLAN ethertype in
   __vlan_hwaccel_put_tag().

2 years agoiavf: Add support VIRTCHNL_VF_OFFLOAD_VLAN_V2 during netdev config
Brett Creeley [Tue, 30 Nov 2021 00:16:01 +0000 (16:16 -0800)]
iavf: Add support VIRTCHNL_VF_OFFLOAD_VLAN_V2 during netdev config

Based on VIRTCHNL_VF_OFFLOAD_VLAN_V2, the VF can now support more VLAN
capabilities (i.e. 802.1AD offloads and filtering). In order to
communicate these capabilities to the netdev layer, the VF needs to
parse its VLAN capabilities based on whether it was able to negotiation
VIRTCHNL_VF_OFFLOAD_VLAN or VIRTCHNL_VF_OFFLOAD_VLAN_V2 or neither of
these.

In order to support this, add the following functionality:

iavf_get_netdev_vlan_hw_features() - This is used to determine the VLAN
features that the underlying hardware supports and that can be toggled
off/on based on the negotiated capabiltiies. For example, if
VIRTCHNL_VF_OFFLOAD_VLAN_V2 was negotiated, then any capability marked
with VIRTCHNL_VLAN_TOGGLE can be toggled on/off by the VF. If
VIRTCHNL_VF_OFFLOAD_VLAN was negotiated, then only VLAN insertion and/or
stripping can be toggled on/off.

iavf_get_netdev_vlan_features() - This is used to determine the VLAN
features that the underlying hardware supports and that should be
enabled by default. For example, if VIRTHCNL_VF_OFFLOAD_VLAN_V2 was
negotiated, then any supported capability that has its ethertype_init
filed set should be enabled by default. If VIRTCHNL_VF_OFFLOAD_VLAN was
negotiated, then filtering, stripping, and insertion should be enabled
by default.

Also, refactor iavf_fix_features() to take into account the new
capabilities. To do this, query all the supported features (enabled by
default and toggleable) and make sure the requested change is supported.
If VIRTCHNL_VF_OFFLOAD_VLAN_V2 is successfully negotiated, there is no
need to check VIRTCHNL_VLAN_TOGGLE here because the driver already told
the netdev layer which features can be toggled via netdev->hw_features
during iavf_process_config(), so only those features will be requested
to change.

iavf: Add support for VIRTCHNL_VF_OFFLOAD_VLAN_V2 negotiation

In order to support the new VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability the
VF driver needs to rework it's initialization state machine and reset
flow. This has to be done because successful negotiation of
VIRTCHNL_VF_OFFLOAD_VLAN_V2 requires the VF driver to perform a second
capability request via VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS before
configuring the adapter and its netdev.

Add the VIRTCHNL_VF_OFFLOAD_VLAN_V2 bit when sending the
VIRTHCNL_OP_GET_VF_RESOURECES message. The underlying PF will either
support VIRTCHNL_VF_OFFLOAD_VLAN or VIRTCHNL_VF_OFFLOAD_VLAN_V2 or
neither. Both of these offloads should never be supported together.

Based on this, add 2 new states to the initialization state machine:

__IAVF_INIT_GET_OFFLOAD_VLAN_V2_CAPS
__IAVF_INIT_CONFIG_ADAPTER

The __IAVF_INIT_GET_OFFLOAD_VLAN_V2_CAPS state is used to request/store
the new VLAN capabilities if and only if VIRTCHNL_VLAN_OFFLOAD_VLAN_V2
was successfully negotiated in the __IAVF_INIT_GET_RESOURCES state.

The __IAVF_INIT_CONFIG_ADAPTER state is used to configure the
adapter/netdev after the resource requests have finished. The VF will
move into this state regardless of whether it successfully negotiated
VIRTCHNL_VF_OFFLOAD_VLAN or VIRTCHNL_VF_OFFLOAD_VLAN_V2.

Also, add a the new flag IAVF_FLAG_AQ_GET_OFFLOAD_VLAN_V2_CAPS and set
it during VF reset. If VIRTCHNL_VF_OFFLOAD_VLAN_V2 was successfully
negotiated then the VF will request its VLAN capabilities via
VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS during the reset. This is needed
because the PF may change/modify the VF's configuration during VF reset
(i.e. modifying the VF's port VLAN configuration).

This also, required the VF to call netdev_update_features() since its
VLAN features may change during VF reset. Make sure to call this under
rtnl_lock().

2 years agovirtchnl: Add support for new VLAN capabilities
Brett Creeley [Tue, 30 Nov 2021 00:15:59 +0000 (16:15 -0800)]
virtchnl: Add support for new VLAN capabilities

Currently VIRTCHNL only allows for VLAN filtering and offloads to happen
on a single 802.1Q VLAN. Add support to filter and offload on inner,
outer, and/or inner + outer VLANs.

This is done by introducing the new capability
VIRTCHNL_VF_OFFLOAD_VLAN_V2. The flow to negotiate this new capability
is shown below.

1. VF - sets the VIRTCHNL_VF_OFFLOAD_VLAN_V2 bit in the
   virtchnl_vf_resource.vf_caps_flags during the
   VIRTCHNL_OP_GET_VF_RESOURCES request message. The VF should also set
   the VIRTCHNL_VF_OFFLOAD_VLAN bit in case the PF driver doesn't support
   the new capability.

2. PF - sets the VLAN capability bit it supports in the
   VIRTCHNL_OP_GET_VF_RESOURCES response message. This will either be
   VIRTCHNL_VF_OFFLOAD_VLAN_V2, VIRTCHNL_VF_OFFLOAD_VLAN, or none.

3. VF - If the VIRTCHNL_VF_OFFLOAD_VLAN_V2 capability was ACK'd by the
   PF, then the VF needs to request the VLAN capabilities of the
   PF/Device by issuing a VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS request.
   If the VIRTCHNL_VF_OFFLOAD_VLAN capability was ACK'd then the VF
   knows only single 802.1Q VLAN filtering/offloads are supported. If no
   VLAN capability is ACK'd then the PF/Device doesn't support hardware
   VLAN filtering/offloads for this VF.

4. PF - Populates the virtchnl_vlan_caps structure based on what it
   allows/supports for that VF and sends that response via
   VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS.

After VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS is successfully negotiated
the VF driver needs to interpret the capabilities supported by the
underlying PF/Device. The VF will be allowed to filter/offload the
inner 802.1Q, outer (various ethertype), inner 802.1Q + outer
(various ethertypes), or none based on which fields are set.

The VF will also need to interpret where the VLAN tag should be inserted
and/or stripped based on the negotiated capabilities.

  test_syncookie:FAIL:Unexpected syncookie states gen_cookie:80326634 recv_cookie:0
  bpf prog error at line 97

"error at line 97" means the bpf prog cannot find the listening socket
when the final ack is received.  It then skipped processing
the syncookie in the final ack which then led to "recv_cookie:0".

The problem is the userspace program did not do accept() and went
ahead to close(listen_fd) before the kernel (and the bpf prog) had
a chance to process the final ack.

The fix is to add accept() call so that the userspace will wait for
the kernel to finish processing the final ack first before close()-ing
everything.

Daniel Borkmann [Wed, 15 Dec 2021 22:02:19 +0000 (22:02 +0000)]
bpf: Fix signed bounds propagation after mov32

For the case where both s32_{min,max}_value bounds are positive, the
__reg_assign_32_into_64() directly propagates them to their 64 bit
counterparts, otherwise it pessimises them into [0,u32_max] universe and
tries to refine them later on by learning through the tnum as per comment
in mentioned function. However, that does not always happen, for example,
in mov32 operation we call zext_32_to_64(dst_reg) which invokes the
__reg_assign_32_into_64() as is without subsequent bounds update as
elsewhere thus no refinement based on tnum takes place.

Thus, not calling into the __update_reg_bounds() / __reg_deduce_bounds() /
__reg_bound_offset() triplet as we do, for example, in case of ALU ops via
adjust_scalar_min_max_vals(), will lead to more pessimistic bounds when
dumping the full register state:

Before fix:

  0: (b4) w0 = -1
  1: R0_w=invP4294967295
     (id=0,imm=ffffffff,
      smin_value=4294967295,smax_value=4294967295,
      umin_value=4294967295,umax_value=4294967295,
      var_off=(0xffffffff; 0x0),
      s32_min_value=-1,s32_max_value=-1,
      u32_min_value=-1,u32_max_value=-1)

  1: (bc) w0 = w0
  2: R0_w=invP4294967295
     (id=0,imm=ffffffff,
      smin_value=0,smax_value=4294967295,
      umin_value=4294967295,umax_value=4294967295,
      var_off=(0xffffffff; 0x0),
      s32_min_value=-1,s32_max_value=-1,
      u32_min_value=-1,u32_max_value=-1)

Technically, the smin_value=0 and smax_value=4294967295 bounds are not
incorrect, but given the register is still a constant, they break assumptions
about const scalars that smin_value == smax_value and umin_value == umax_value.

After fix:

  0: (b4) w0 = -1
  1: R0_w=invP4294967295
     (id=0,imm=ffffffff,
      smin_value=4294967295,smax_value=4294967295,
      umin_value=4294967295,umax_value=4294967295,
      var_off=(0xffffffff; 0x0),
      s32_min_value=-1,s32_max_value=-1,

      s32_min_value=-1,s32_max_value=-1,
      u32_min_value=-1,u32_max_value=-1)

Without the smin_value == smax_value and umin_value == umax_value invariant
being intact for const scalars, it is possible to leak out kernel pointers
from unprivileged user space if the latter is enabled. For example, when such
registers are involved in pointer arithmtics, then adjust_ptr_min_max_vals()
will taint the destination register into an unknown scalar, and the latter
can be exported and stored e.g. into a BPF map value.

sit: do not call ipip6_dev_free() from sit_init_net()

ipip6_dev_free is sit dev->priv_destructor, already called
by register_netdevice() if something goes wrong.

Alternative would be to make ipip6_dev_free() robust against
multiple invocations, but other drivers do not implement this
strategy.

2 years agonet: systemport: Add global locking for descriptor lifecycle
Florian Fainelli [Wed, 15 Dec 2021 20:24:49 +0000 (12:24 -0800)]
net: systemport: Add global locking for descriptor lifecycle

The descriptor list is a shared resource across all of the transmit queues, and
the locking mechanism used today only protects concurrency across a given
transmit queue between the transmit and reclaiming. This creates an opportunity
for the SYSTEMPORT hardware to work on corrupted descriptors if we have
multiple producers at once which is the case when using multiple transmit
queues.

This was particularly noticeable when using multiple flows/transmit queues and
it showed up in interesting ways in that UDP packets would get a correct UDP
header checksum being calculated over an incorrect packet length. Similarly TCP
packets would get an equally correct checksum computed by the hardware over an
incorrect packet length.

The SYSTEMPORT hardware maintains an internal descriptor list that it re-arranges
when the driver produces a new descriptor anytime it writes to the
WRITE_PORT_{HI,LO} registers, there is however some delay in the hardware to
re-organize its descriptors and it is possible that concurrent TX queues
eventually break this internal allocation scheme to the point where the
length/status part of the descriptor gets used for an incorrect data buffer.

The fix is to impose a global serialization for all TX queues in the short
section where we are writing to the WRITE_PORT_{HI,LO} registers which solves
the corruption even with multiple concurrent TX queues being used.

smc_release() has to block until one worker comes to free, which
is equivalent to wait another smc_connnect_work() to finish.

In order to fix this, There are two changes:

1. For those idle smc_connect_work(), cancel it from the workqueue; for
   executing smc_connect_work(), waiting for it to finish. For that
   purpose, replace flush_work() with cancel_work_sync().

2. Since smc_connect() hold a reference for passive closing, if
   smc_connect_work() has been cancelled, release the reference.

wcn36xx: Implement beacon filtering

The prima driver facilitates the direct programming of beacon filter tables via
SMD commands.

The purpose of beacon filters is quote:

/* When beacon filtering is enabled, firmware will
 * analyze the selected beacons received during BMPS,
 * and monitor any changes in the IEs as listed below.
 * The format of the table is:
 *    - EID
 *    - Check for IE presence
 *    - Byte offset
 *    - Byte value
 *    - Bit Mask
 *    - Byte reference
 */

The default filter table looks something like this:

tBeaconFilterIe gaBcnFilterTable[12] =
{
  { WLAN_EID_DS_PARAMS, 0u, { 0u, 0u, 0u, 0u } },
  { WLAN_EID_ERP_INFO, 0u, { 0u, 0u, 248u, 0u } },
  { WLAN_EID_EDCA_PARAM_SET, 0u, { 0u, 0u, 240u, 0u } },
  { WLAN_EID_QOS_CAPA, 0u, { 0u, 0u, 240u, 0u } },
  { WLAN_EID_CHANNEL_SWITCH, 1u, { 0u, 0u, 0u, 0u } },
  { WLAN_EID_QUIET, 1u, { 0u, 0u, 0u, 0u } },
  { WLAN_EID_HT_OPERATION, 0u, { 0u, 0u, 0u, 0u } },
  { WLAN_EID_HT_OPERATION, 0u, { 1u, 0u, 248u, 0u } },
  { WLAN_EID_HT_OPERATION, 0u, { 2u, 0u, 235u, 0u } },
  { WLAN_EID_HT_OPERATION, 0u, { 5u, 0u, 253u, 0u } },
  { WLAN_EID_PWR_CONSTRAINT, 0u, { 0u, 0u, 0u, 0u } },
  { WLAN_EID_OPMODE_NOTIF, 0u, { 0u, 0u, 0u, 0u } }
};

Add in an equivalent filter set as present in the prima Linux driver.
For now omit the beacon filter "rem" command as the driver does not have an
explicit call to that SMD command. The filter mask should only count when
we are inside BMPS anyway.

Replicating the ability to program the filter table gives us scope to add and
remove elements in future. For now though this patch makes the rote-copy of the
downstream Linux beacon filter table, which we can tweak as desired from now
on.

2 years agonet: prestera: flower template support
Volodymyr Mytnyk [Wed, 15 Dec 2021 10:07:30 +0000 (12:07 +0200)]
net: prestera: flower template support

Add user template explicit support. At this moment, max
TCAM rule size is utilized for all rules, doesn't matter
which and how much flower matches are provided by user. It
means that some of TCAM space is wasted, which impacts
the number of filters that can be offloaded.

Introducing the template, allows to have more HW offloaded
filters by specifying the template explicitly.

Example:
  tc qd add dev PORT clsact
  tc chain add dev PORT ingress protocol ip \
    flower dst_ip 0.0.0.0/16
  tc filter add dev PORT ingress protocol ip \
    flower skip_sw dst_ip 1.2.3.4/16 action drop

NOTE: chain 0 is the default chain id for "tc chain" & "tc filter"
      command, so it is omitted in the example above.

This patch adds only template support for default chain 0 suppoerted
by prestera driver at this moment. Chains are not supported yet,
and will be added later.

KASAN reports an out-of-bounds read in rk_gmac_setup on the line:

This happens for most platforms since the regs flexible array member is
empty, so the memory after the ops structure is being read here.  It
seems that mostly this happens to contain zero anyway, so we get lucky
and everything still works.

To avoid adding redundant data to nearly all the ops structures, add a
new flag to indicate whether the regs field is valid and avoid this loop
when it is not.
