Multicast improvement in Ocelot and Felix drivers
This series makes some basic multicast forwarding functionality work for
Felix DSA and for Ocelot switchdev. IGMP/MLD snooping in Felix is still
missing, and there are other improvements to be made in the general area
of multicast address filtering towards the CPU, but let's get these
hardware-specific fixes out of the way first.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The current procedure for installing a multicast address is hardcoded
for IPv4. But, in the ocelot hardware, there are 3 different procedures
for IPv4, IPv6 and for regular L2 multicast.
For IPv6 (33-33-xx-xx-xx-xx), it's the same as for IPv4
(01-00-5e-xx-xx-xx), except that the destination port mask is stuffed
into first 2 bytes of the MAC address except into first 3 bytes.
For plain Ethernet multicast, there's no port-in-address stuffing going
on, instead the DEST_IDX (pointer to PGID) is used there, just as for
unicast. So we have to use one of the nonreserved multicast PGIDs that
the hardware has allocated for this purpose.
This patch classifies the type of multicast address based on its first
bytes, then redirects to one of the 3 different hardware procedures.
Note that this gives us a really better way of redirecting PTP frames
sent at 01-1b-19-00-00-00 to the CPU. Previously, Yangbo Lu tried to add
a trapping rule for PTP EtherType but got a lot of pushback:
https://patchwork.ozlabs.org/project/netdev/patch/20190813025214.18601-5-yangbo.lu@nxp.com/
But right now, that isn't needed at all. The application stack (ptp4l)
does this for the PTP multicast addresses it's interested in (which are
configurable, and include 01-1b-19-00-00-00):
memset(&mreq, 0, sizeof(mreq));
mreq.mr_ifindex = index;
mreq.mr_type = PACKET_MR_MULTICAST;
mreq.mr_alen = MAC_LEN;
memcpy(mreq.mr_address, addr1, MAC_LEN);
err1 = setsockopt(fd, SOL_PACKET, PACKET_ADD_MEMBERSHIP, &mreq,
sizeof(mreq));
Into the kernel, this translates into a dev_mc_add on the switch network
interfaces, and our drivers know that it means they should translate it
into a host MDB address (make the CPU port be the destination).
Previously, this was broken because all mdb addresses were treated as
IPv4 (which 01-1b-19-00-00-00 obviously is not).

When used in DSA mode (as seen in Felix), the DEST_IDX in the MAC table
should point to the PGID for the CPU port (PGID_CPU) and not for the
Ethernet port where the CPU queues are redirected to (also known as Node
Processor Interface - NPI).
Because for Felix this distinction shouldn't really matter (from DSA
perspective, the NPI port _is_ the CPU port), make the ocelot library
act upon the CPU port when NPI mode is enabled. This has no effect for
the mscc_ocelot driver for VSC7514, because that does not use NPI (and
ocelot->npi is -1).

The ocelot hardware designers have made some hacks to support multicast
IPv4 and IPv6 addresses. Normally, the MAC table matches on MAC
addresses and the destination ports are selected through the DEST_IDX
field of the respective MAC table entry. The DEST_IDX points to a Port
Group ID (PGID) which contains the bit mask of ports that frames should
be forwarded to. But there aren't a lot of PGIDs (only 80 or so) and
there are clearly many more IP multicast addresses than that, so it
doesn't scale to use this PGID mechanism, so something else was done.
Since the first portion of the MAC address is known, the hack they did
was to use a single PGID for _flooding_ unknown IPv4 multicast
(PGID_MCIPV4 == 62), but for known IP multicast, embed the destination
ports into the first 3 bytes of the MAC address recorded in the MAC
table.
The VSC7514 datasheet explains it like this:
3.9.1.5 IPv4 Multicast Entries
MAC table entries with the ENTRY_TYPE = 2 settings are interpreted
as IPv4 multicast entries.
IPv4 multicasts entries match IPv4 frames, which are classified to
the specified VID, and which have DMAC = 0x01005Exxxxxx, where
xxxxxx is the lower 24 bits of the MAC address in the entry.
Instead of a lookup in the destination mask table (PGID), the
destination set is programmed as part of the entry MAC address. This
is shown in the following table.
Table 78: IPv4 Multicast Destination Mask
Destination Ports Record Bit Field
---------------------------------------------
Ports 10-0 MAC[34-24]
Example: All IPv4 multicast frames in VLAN 12 with MAC 01005E112233 are
to be forwarded to ports 3, 8, and 9. This is done by inserting the
following entry in the MAC table entry:
VALID = 1
VID = 12
MAC = 0x000308112233
ENTRY_TYPE = 2
DEST_IDX = 0
But this procedure is not at all what's going on in the driver. In fact,
the code that embeds the ports into the MAC address looks like it hasn't
actually been tested. This patch applies the procedure described in the
datasheet.
Since there are many other fixes to be made around multicast forwarding
until it works properly, there is no real reason for this patch to be
backported to stable trees, or considered a real fix of something that
should have worked.

mlxsw: Offload TC action pedit munge tcp/udp sport/dport
Petr says:
On Spectrum-2 and Spectrum-3, it is possible to overwrite L4 port number of
a TCP or UDP packet in the ACL engine. That corresponds to the pedit munges
of tcp and udp sport resp. dport fields. Offload these munges on the
systems where they are supported.
The current offloading code assumes that all systems support the same set
of fields. This now changes, so in patch #1 first split handling of pedit
munges by chip type. The analysis of which packet field a given munge
describes is kept generic.
Patch #2 introduces the new flexible action fields. Patch #3 then adds the
new pedit fields, and dispatches on them on Spectrum>1.

A netdevice may be marked as detached because the parent is
runtime-suspended and not accessible whilst interface or link is down.
An example are PCI network devices that go into PCI D3hot, see e.g.
__igc_shutdown() or rtl8169_net_suspend().
If netdevice is down and marked as detached we can only open it if
we runtime-resume it before __dev_open() calls netif_device_present().
Therefore, if netdevice is detached, try to runtime-resume the parent
and only return with an error if it's still detached.

bonding: initial support for hardware crypto offload
This is an initial functional implementation for doing pass-through of
hardware encryption from bonding device to capable slaves, in active-backup
bond setups. This was developed and tested using ixgbe-driven Intel x520
interfaces with libreswan and a transport mode connection, primarily using
netperf, with assorted connection failures forced during transmission. The
failover works quite well in my testing, and overall performance is right
on par with offload when running on a bare interface, no bond involved.
Caveats: this is ONLY enabled for active-backup, because I'm not sure
how one would manage multiple offload handles for different devices all
running at the same time in the same xfrm, and it relies on some minor
changes to both the xfrm code and slave device driver code to get things
to behave, and I don't have immediate access to any other hardware that
could function similarly, but the NIC driver changes are minimal and
straight-forward enough that I've included what I think ought to be
enough for mlx5 devices too.

Currently, this support is limited to active-backup mode, as I'm not sure
about the feasilibity of mapping an xfrm_state's offload handle to
multiple hardware devices simultaneously, and we rely on being able to
pass some hints to both the xfrm and NIC driver about whether or not
they're operating on a slave device.
I've tested this atop an Intel x520 device (ixgbe) using libreswan in
transport mode, succesfully achieving ~4.3Gbps throughput with netperf
(more or less identical to throughput on a bare NIC in this system),
as well as successful failover and recovery mid-netperf.
v2: just use CONFIG_XFRM_OFFLOAD for wrapping, isolate more code with it
