One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL)
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL)
Notice that, in this case, variable alloc_size is not necessary, hence
it is removed.

100GbE Intel Wired LAN Driver Updates 2019-02-22
This series contains updates to the ice driver only.
Bruce adds the __always_unused attribute to a parameter to avoid
compiler warnings when using -Wunused-parameter. Fixed unnecessary
type-casting and the use of sizeof(). Fix the allocation of structs
that have become memory hogs, so allocate them in heaps and fix all the
associated references. Fixed the "possible" numeric overflow issues
that were caught with static analysis.
Maciej fixes the maximum MTU calculation by taking into account double
VLAN tagging amd ensure that the operations are done in the correct
order.
Victor fixes the supported node calculation, where we were not taking
into account if there is space to add the new VSI or intermediate node
above that layer, then it is not required to continue the calculation.
Added a check for a leaf node presence for a given VSI, which is needed
before removing a VSI.
Jake fixes an issue where the VSI list is shared, so simply removing a
VSI from the list will cause issues for the other users who reference
the list. Since we also free the memory, this could lead to
segmentation faults.
Brett fixes an issue where driver unload could cause a system reboot
when intel_iommu=on parameter is set. The issue is that we are not
clearing the CAUSE_ENA bit for the appropriate control queues register
when freeing the miscellaneous interrupt vector.
Mitch is so kind, he prevented spamming the VF with link messages when
the link status really has not changed. Updates the driver to use the
absolute vector ID and not the per-PF vector ID for the VF MSIx vector
allocation.
Lukasz fixes the ethtool pause parameter for the ice driver, which was
originally based off the link status but is now based off the PHY
configuration. This is to resolve an issue where pause parameters could
be set while link was down.
Jesse updates the string that reports statistics so the string does not
get modified at runtime and cause reports of string truncation.

On older devices like X710 and X722, the VF's ARQLEN register is cleared
on reset, so the VF driver uses that register to detect an unannounced
reset. Unfortunately, on devices controlled by ice, this register is NOT
cleared on reset. This causes the VF to miss resets, and even on
properly-announced resets, the VF driver complains that it didn't see
the reset.
To fix this, we'll do it in software. When we handle a VF reset (whether
triggered by software or VFLR), clear this register after the HW reset
is complete.

Currently if the kernel has the intel_iommu=on parameter set, on some
platforms removing the driver causes a system reboot. In initialization
we associate the control queue interrupts with the pf->hw_oicr_idx and
enable the interrupts by setting the CAUSE_ENA bit. The problem comes
on teardown because we are not clearing the CAUSE_ENA bit for the
control queues, but the vector at pf->hw_oicr_idx (miscellaneous
interrupt vector) gets disabled.
Fix this by clearing the CAUSE_ENA bit in the appropriate control queue
registers on when freeing the miscellaneous interrupt vector. Also,
move the call to ice_free_irq_msix_misc() to after ice_deinit_sw() in
ice_remove() because ice_deinit_sw() makes an AQ call, but
ice_free_irq_msix_misc() disables the miscellaneous vector and it's
associated interrupts.
Also, create two small helper functions to enable and disable the
control queue interrupts respectively.

When adding multiple VLANs to the same VSI, the ice_add_vlan code will
share the VSI list, so as not to create multiple unnecessary VSI lists.
Consider the following flow
ice_add_vlan(hw, <VSI 0 VID 7, VSI 0 VID 8, VSI 0 VID 9>)
Where we add three VLAN filters for VIDs 7, 8, and 9, all for VSI 0.
The ice_add_vlan will create a single vsi_list and share it among all
the filters.
Later, if we try to remove a VLAN,
ice_remove_vlan(hw, <VSI 0 VID 7>)
Then the removal code will update the vsi_list and remove VSI 0 from it.
But, since the vsi_list is shared, this breaks the list for the other
users who reference it. We actually even free the VSI list memory, and
may result in segmentation faults.
This is due to the way that VLAN rule share VSI lists with reference
counts, and is caused because we call ice_rem_update_vsi_list even when
the ref_cnt is greater than one.
To fix this, handle the case where ref_cnt is greater than one
separately. In this case, we need to remove the associated rule without
modifying the vsi_list, since it is currently being referenced by
another rule. Instead, we just need to decrement the VSI list ref_cnt.
The case for handling sharing of VSI lists with multiple VSIs is not
currently supported by this code. No such rules will be created today,
and this code will require changes if/when such code is added.

For MR ACL profile is does not make sense to do periodical rehashes, as
there is only one mask in use during the whole vregion lifetime.
Therefore periodical work is scheduled but the rehash never happens.
So allow to enable/disable rehash for the whole group, which is added
per-profile. Disable rehashing for MR profile.
Addition to the vregion list is done only in case the rehash is enable
on the particular vregion. Also, the addition is moved after delayed
work init to avoid schedule of uninitialized work
from vregion_rehash_intrvl_set(). Symmetrically, deletion from

The current code reports a link as up if all devices (except a few
blacklisted ones) report the link as up. This breaks Aquantia AQCS109
for lower speeds because on this PHY the PCS link status reflects a
10G link only. For Marvell there's a similar issue, therefore PHYXS
device isn't checked.
There may be more PHYs where depending on the mode the link status
of only selected devices is relevant.
For now it seems to be sufficient to check the link status of the
PMAPMD device only. Leave the loop in the code to be prepared in
case we have to add functionality to check more than one device,
depending on the mode.
Successfully tested on a board with an AQCS109.

This fixes a regression introduced by
commit 0d2e778e38
"net: phy: replace PHY_HAS_INTERRUPT with a check for
config_intr and ack_interrupt".
This assumes that a PHY cannot trigger interrupt unless
it has .config_intr() or .ack_interrupt() implemented.
A later patch makes the code assume both need to be
implemented for interrupts to be present.
But this PHY (which is inside a DSA) will happily
fire interrupts without either callback.
Implement dummy callbacks for .config_intr() and
.ack_interrupt() in the phy header to fix this.
Tested on the RTL8366RB on D-Link DIR-685.

Add Spectrum-2 ASIC port type-speed operations.
Since multiple ethtool link modes are represented using a single bit in the
ASIC, the driver forces the user to configure all types per a specific
speed. For example, if the user wants to advertise 100Gbps 4-lanes speed,
he should advertise all the types of 100Gbps 4-lanes speed that are
supported by the ASIC as shown below:
Supported ethtool bits for 100Gbps 4-lanes:
0x1000000000 100000baseKR4 Full
0x2000000000 100000baseSR4 Full
0x4000000000 100000baseCR4 Full
0x8000000000 100000baseLR4_ER4 Full

In Virtual Ethernet Port Aggregator (VEPA) mode, the packet skips
the system internal virtual switch and forwards to external network
switch. In Mellanox HCA case, the virtual switch is the HCA's Eswitch.
To support this, an new FDB flow table are created with level 0 and
linked to the existing FDB flow table in legacy mode. By default,
VEPA is turned off and this FDB flow table is empty. When VEPA is
turned on, two rules are created. One rule to forward on uplink vport
traffic to the legacy FDB. The other rule forward all other traffic
to uplink vport.
Other design alternatives were not chosen as explained below:
1. Create a forward rule in ACL flow table (most efficient design).
This approach is the not chosen because firmware does not support
forward rule to uplink vport (0xffff) for ACL flow table.
2. Add additional source port criteria in all the FDB rules to make the
FDB rules to be received rules only. This approach is not chosen because
it is not efficient as there can many rules in the FDB and VEPA mode
cannot be controlled per vport.
3. Add a highest prioirty flow group in the existing legacy FDB Flow
Table instead of a new flow table. This approoach does not work because the
new flow group has the same match criteria as the promiscuous flow group
and mlx5_add_flow_rules does not allow specifying flow group.

Flow entropy is calculated on the inner packet headers and used for
flow distribution in processing, routing etc. For GRE-type
encapsulations the entropy value is placed in the eight LSB of the key
field in the GRE header as defined in NVGRE RFC 7637. For UDP based
encapsulations the entropy value is placed in the source port of the
UDP header.
The hardware may support entropy calculation specifically for GRE and
for all tunneling protocols. With commit df2ef3bff1 ("net/mlx5e: Add
GRE protocol offloading") GRE is offloaded, but the hardware is
configured by default to calculate flow entropy so packets transmitted
on the wire have a wrong key. To support UDP based tunnels (i.e VXLAN),
GRE (i.e. no flow entropy) and NVGRE (i.e. with flow entropy) the
hardware behaviour must be controlled by the driver.
Ensure port entropy calculation is enabled for offloaded VXLAN tunnels
and disable port entropy calculation in the presence of offloaded GRE
tunnels by monitoring the presence of entropy enabling tunnels (i.e
VXLAN) and entropy disabing tunnels (i.e GRE).

If the socket was created with socket(AF_PACKET, SOCK_RAW, 0),
skb->protocol will be unset, __skb_flow_dissect() will fail, and
skb_probe_transport_header() will fall back to the offset_hint, making
the resulting skb_transport_offset incorrect.
If, however, there is no transport header in the packet,
transport_header shouldn't be set to an arbitrary value.
Fix it by leaving the transport offset unset if it couldn't be found, to
be explicit rather than to fill it with some wrong value. It changes the
behavior, but if some code relied on the old behavior, it would be
broken anyway, as the old one is incorrect.

applying that through a side branch to record some details
* CSA improvements
* HE (802.11ax) updates to Draft 3.3
* strongly typed element iteration/etc. to make such code more

Having one work queue for receive mode configuration ndo_set_rx_mode()
call for all VFs results in making each of them wait till the
set_rx_mode() call completes for another VF if any of close, set
receive mode and change flags calls being already invoked. Potentially
this could cause device state change before appropriate call of receive
mode configuration completes, so the call itself became meaningless,
corrupt data or break configuration sequence.
We don't need any delays in NIC VF configuration sequence so having delayed
work call with 0 delay has no sense.
This commit is to implement one work queue for each NIC VF for set_rx_mode
task and to let them work independently and replacing delayed_work
with work_struct.

When running Docker with userns isolation e.g. --userns-remap="default"
and spawning up some containers with CAP_NET_ADMIN under this realm, I
noticed that link changes on ipvlan slave device inside that container
can affect all devices from this ipvlan group which are in other net
namespaces where the container should have no permission to make changes
to, such as the init netns, for example.
This effectively allows to undo ipvlan private mode and switch globally to
bridge mode where slaves can communicate directly without going through
hostns, or it allows to switch between global operation mode (l2/l3/l3s)
for everyone bound to the given ipvlan master device. libnetwork plugin
here is creating an ipvlan master and ipvlan slave in hostns and a slave
each that is moved into the container's netns upon creation event.
* In hostns:
# ip -d a
[...]
8: cilium_host@bond0: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000

* Spawn container & change ipvlan mode setting inside of it:
# docker run -dt --cap-add=NET_ADMIN --network cilium-net --name client -l app=test cilium/netperf
9fff485d69dcb5ce37c9e33ca20a11ccafc236d690105aadbfb77e4f4170879c

inet 10.41.0.1/32 scope link cilium_host
valid_lft forever preferred_lft forever
[...]
Same l3 -> l2 switch would also happen by creating another slave inside
the container's network namespace when specifying the existing cilium0
link to derive the actual (bond0) master:
# docker exec -ti client ip link add link cilium0 name cilium1 type ipvlan mode l2
# docker exec -ti client ip -d a
[...]

inet 10.41.197.43/32 brd 10.41.197.43 scope global cilium0

8: cilium_host@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000

valid_lft forever preferred_lft forever
[...]
One way to mitigate it is to check CAP_NET_ADMIN permissions of
the ipvlan master device's ns, and only then allow to change
mode or flags for all devices bound to it. Above two cases are
then disallowed after the patch.

port-priority resp. port-TC. The default configuration depends on the
chip type. Therefore keep the tables and their lengths in struct
mlxsw_sp_sb_vals. Redirect the references from the global definitions to
the fields.

The SBPR register configures shared buffer pools. The default
configuration depends on the chip type. Therefore keep it in struct
mlxsw_sp_sb_vals. Redirect the one reference from the global array to
the field.
Because the pool descriptor ID is implicit in the ordering of array
members, both this array and the pool descriptor array have the same
length. Therefore reuse mlxsw_sp_sb.pool_dess_len for the purpose of
determining the length of SBPR array.
Drop the now useless MLXSW_SP_SB_PRS_LEN.

Keep the table of pool descriptors and its length in struct
mlxsw_sp_sb_vals so that it can be specialized per chip type. Redirect
all users from the global definitions to the mlxsw_sp_sb fields.
Give mlxsw_sp_pool_count() an extra mlxsw_sp parameter so that it can
access the descriptor table.

Spectrum-2 will be configured with a different set of pools than
Spectrum-1. The size of prs and pms buffers will therefore depend on the
chip type of the device.
Therefore, instead of reserving an array directly in a structure
definition, allocate the buffer in mlxsw_sp_sb_port{,s}_init().

TBU interrupt is a normal interrupt and can be used to trigger the
cleaning of TX path. Lets check if it's active in DMA interrupt handler.
While at it, refactor a little bit the function:
- Don't check if RI is enabled because at function exit we will
only clear the interrupts that are enabled so, no event will
be missed.
In my tests withe XGMAC2 this increased performance.

Commit 8fce333170 introduced the concept of NAPI per-channel and
independent cleaning of TX path.
This is currently breaking performance in some cases. The scenario
happens when all packets are being received in Queue 0 but the TX is
performed in Queue != 0.
Fix this by using different NAPI instances per each TX and RX queue, as
suggested by Florian.
Changes from v2:
- Only force restart transmission if there are pending packets
Changes from v1:
- Pass entire ring size to TX clean path (Florian)

With the bridge no longer calling switchdev_port_attr_get() to obtain
the supported bridge port flags from a driver but instead trying to set
the bridge port flags directly and relying on driver to reject
unsupported configurations, we can effectively get rid of
switchdev_port_attr_get() entirely since this was the only place where
it was called.

Now that we have converted the bridge code and the drivers to check for
bridge port(s) flags at the time we try to set them, there is no need
for a get() -> set() sequence anymore and
SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS_SUPPORT therefore becomes unused.

This patch fixes a subtle PACKET_ORIGDEV regression which was a side
effect of fixes introduced by:
6a9e461f6f bonding: pass link-local packets to bonding master also.
... to:
b89f04c61e bonding: deliver link-local packets with skb->dev set to link that packets arrived on
While 6a9e461f6f restored pre-b89f04c61efe presence of link-local
packets on bonding masters (which is required e.g. by linux bridges
participating in spanning tree or needed for lab-like setups created
with group_fwd_mask) it also caused the originating device
information to be lost due to cloning.
Maciej Żenczykowski proposed another solution that doesn't require
packet cloning and retains original device information - instead of
returning RX_HANDLER_PASS for all link-local packets it's now limited
only to packets from inactive slaves.
At the same time, packets passed to bonding masters retain correct
information about the originating device and PACKET_ORIGDEV can be used
to determine it.
This elegantly solves all issues so far:
- link-local packets that were removed from bonding masters
- LLDP daemons being forced to explicitly bind to slave interfaces
- PACKET_ORIGDEV having no effect on bond interfaces
Fixes: 6a9e461f6f (bonding: pass link-local packets to bonding master also.)
