- RTE_ETH_EVENT_MACSEC
This event will occur when the PN counter in a MACsec connection
reaches the exhaustion threshold.

If these flags are advertised by a PMD, the NIC supports the MACsec
offload. The incoming MACsec traffics can be offloaded transparently
after the MACsec offload is configured correctly by the application.
And the application can set the PKT_TX_MACSEC flag in mbufs to enable
the MACsec offload for the packets to be transmitted.

Below MACsec offload commands are added:
- set macsec offload <port_id> on encrypt on|off replay-protect on|off
- set macsec offload <port_id> off
- set macsec sc tx|rx <port_id> <mac> <pi>
- set macsec sa tx|rx <port_id> <idx> <an> <pn> <key>
Also update the testpmd user guide.

I'm not commenting on any specific patch from this series, however I'm
noticing this new trend of working around ethdev to add PMD-specific APIs.
I would like to make sure it's not getting out of hand.
To use the "rte_pmd_ixgbe_macsec_*()" API, applications must be linked with
librte_pmd_ixgbe directly and have the related code under #ifdef
RTE_LIBRTE_IXGBE_PMD like testpmd.
Here we can see this ixgbe-specific API affects rte_mbuf.h and rte_ethdev.h
(new PKT_TX_MACSEC, RTE_ETH_EVENT_MACSEC, DEV_RX_OFFLOAD_MACSEC_STRIP and
DEV_TX_OFFLOAD_MACSEC_INSERT flags).
- Shouldn't these flags have "IXGBE" somewhere in their name and/or be
defined under #ifdef RTE_LIBRTE_IXGBE_PMD?
- Why can't the MACsec API be defined globally, for instance won't i40e
implement it as well someday?
- Why bothering with TX/RX offload capabilities if applications know the
underlying PMD anyway?
Assuming these patches are kept as-is, I suggest we define a reserved space
documented as such for PMD-specific flags wherever they are used.

I think those flags are very generic, simple and innocent, so we could just
define them in the normal way. And currently it seems that we lack a way to
define the PMD-specific flags for mbuf, ethdev, etc.

I think currently we prefer to implement some PMD features based on the
PMD-specific APIs at first to avoid the bloating of the ethdev APIs. And
when it proves to be generic (which means many people really need it and
care about it, and more drivers are really going to implement it), then
we make it as the global ethdev API.

Not every NIC supported by IXGBE supports the MACsec offload. So even
if the application knows it's using IXGBE PMD, it still needs to check
whether the MACsec offload capabilities are supported.

It sounds good to me. But it may involve many pieces of the lib, such
as the mbuf ol_flags, ethdev event type, ethdev offload capabilities,
and so on. So maybe it can be done as another work.
Thank you very much for your comments! :-)

Yes, this is probably the least intrusive approach. I'm just pointing out
that in the meantime, assigned values are not available for other generic
uses which is a problem unless there is a plan to make this API available
globally.
Missing flags and bits could also be defined directly by rte_pmd_ixgbe.h.

Understandable, but then unless the global API remains exactly the same
including the "rte_ixgbe_macsec" prefix (which I think won't happen),
applications need to be rewritten, it's not convenient, and as a result may
prevent adoption due to the following cycle:
- Applications wait for the API to evolve before using MACsec.
- DPDK waits for applications to use the ixgbe MACsec API to improve it.
In the end, flags tied to a single PMD remain allocated in the global
namespace while the API is kept in this temporary state forever.
I think doing the extra work to make it global from the start is worth the
trouble. This step could perhaps be made easier if people agreed that
struct eth_dev_ops (and friends) must be opaque to applications.

OK, I assumed they all did.

Right, that was just an idea from the top of my head, we could define
reserved values only when they become necessary for a PMD as in this case,
e.g. instead of defining PKT_TX_MACSEC, one would define PKT_TX_RESERVED_0
which would be interpreted as MACSEC by ixgbe until this API is exposed
globally.
Other PMDs could implement other unrelated PMD-specific APIs through
RESERVED_0 in the meantime, so we preserve the precious space we have
for global APIs (especially inside mbufs).
Thoughts?

Yeah, I also saw these problems. And I also don't think this is a
perfect way. But it seems that many of us prefer this way, so I just
choose to accept it.

When a certain PMD implemented several different features based on
the PMD-specific API, and many of them need to define some flags in
mbuf or the like, it still needs to waste many bits (i.e. we'll need
to reserve many bits by that time). But any way, I love your idea!
It's much better than the current approach! I'll update my patch.
Thank you very much! ;-)

This patch set adds the MACsec offload support for ixgbe.
The testpmd is also updated to support MACsec cmds.
v2:
- Update the documents for testpmd;
- Update the release notes;
- Reuse the functions provided by base code;
v3:
- Add the missing parts of MACsec mbuf flag and reorganize the patch set;
- Add an ethdev event type for MACsec;
- Advertise the MACsec offload capabilities based on the mac type;
- Minor fixes and improvements;
v4:
- Reserve bits in mbuf and ethdev for PMD specific API;
- Use the reserved bits in PMD specific API;
Tiwei Bie (7):

MACsec (or LinkSec, 802.1AE) is a MAC level encryption/authentication
scheme defined in IEEE 802.1AE that uses symmetric cryptography.
This commit adds the MACsec offload support for ixgbe.

Below MACsec offload commands are added:
- set macsec offload <port_id> on encrypt on|off replay-protect on|off
- set macsec offload <port_id> off
- set macsec sc tx|rx <port_id> <mac> <pi>
- set macsec sa tx|rx <port_id> <idx> <an> <pn> <key>
Also update the testpmd user guide.

Below MACsec offload commands are added:
- set macsec offload <port_id> on encrypt on|off replay-protect on|off
- set macsec offload <port_id> off
- set macsec sc tx|rx <port_id> <mac> <pi>
- set macsec sa tx|rx <port_id> <idx> <an> <pn> <key>
Also update the testpmd user guide.

./tools/dpdk-devbind.py -b igb_uio 07:00.0 07:00.1
2. config the rx port
1). start the testpmd of rx port::
./testpmd -c 0xc --socket-mem 1024,1024 --file-prefix=rx -w 0000:07:00.1 \
-- --port-topology=chained -i --crc-strip
2). set MACsec offload on::
testpmd>set macsec offload 0 on encrypt on replay-protect on
3). set MACsec parameters as rx_port::
testpmd>set macsec sc rx 0 00:00:00:00:00:01 0
testpmd>set macsec sa rx 0 0 0 0 00112200000000000000000000000000
4). set MACsec parameters as tx_port::
testpmd>set macsec sc tx 0 00:00:00:00:00:02 0
testpmd>set macsec sa tx 0 0 0 0 00112200000000000000000000000000
5). set rxonly::
testpmd>set fwd rxonly
6). start::
testpmd>set promisc all on
testpmd>start
3. config the tx port
1). start the testpmd of tx port::
./testpmd -c 0x30 --socket-mem 1024,1024 --file-prefix=tx -w 0000:07:00.0 \
-- --port-topology=chained -i --crc-strip --txqflags=0x0
2). set MACsec offload on::
testpmd>set macsec offload 0 on encrypt on replay-protect on
3). set MACsec parameters as tx_port::
testpmd>set macsec sc tx 0 00:00:00:00:00:01 0
testpmd>set macsec sa tx 0 0 0 0 00112200000000000000000000000000
4). set MACsec parameters as rx_port::
testpmd>set macsec sc rx 0 00:00:00:00:00:02 0
testpmd>set macsec sa rx 0 0 0 0 00112200000000000000000000000000
5). set txonly::
testpmd>set fwd txonly
6). start::
testpmd>start
4. check the result::
testpmd>stop
testpmd>show port xstats 0
stop the packet transmiting on tx_port first, then stop the packet receiving
on rx_port.
check the rx data and tx data:
tx_good_packets == rx_good_packets
out_pkts_encrypted == in_pkts_ok == tx_good_packets == rx_good_packets
out_octets_encrypted == in_octets_decrypted
out_octets_protected == in_octets_validated
if you want to check the content of the packet, use the command::
testpmd>set verbose 1
the received packets are Decrypted.
check the ol_flags:PKT_RX_IP_CKSUM_GOOD
check the content of the packet:
type=0x0800, the ptype of L2,L3,L4: L2_ETHER L3_IPV4 L4_UDP
Test Case 2: MACsec packets send and normal receive
===================================================
1. disable MACsec offload on rx port::
testpmd>set macsec offload 0 off
2. start the the packets transfer
3. check the result::
testpmd>stop
testpmd>show port xstats 0
stop the testpmd on tx_port first, then stop the testpmd on rx_port.
the received packets are encrypted.
check the content of the packet:
type=0x88e5 sw ptype: L2_ETHER - l2_len=14 - Receive queue=0x0
you can't find L3 and L4 infomation in the packet
in_octets_decrypted and in_octets_validated doesn't increase on last data
transfer.
Test Case 3: normal packet send and MACsec receive
==================================================
1. enable MACsec offload on rx port::
testpmd>set macsec offload 0 on encrypt on replay-protect on
2. disable MACsec offload on tx port::
testpmd>set macsec offload 0 off
3. start the the packets transfer
4. check the result::
testpmd>stop
testpmd>show port xstats 0
stop the testpmd on tx_port first, then stop the testpmd on rx_port.
the received packets are not encrypted.
check the content of the packet:
type=0x0800, the ptype of L2,L3,L4: L2_ETHER L3_IPV4 L4_UDP
in_octets_decrypted and out_pkts_encrypted doesn't increase on last data
transfer.
Test Case 4: MACsec send and receive with wrong parameters
==========================================================
1. don't add "--txqflags=0x0" in the tx_port command line.
the MACsec offload can't work. the tx packets are normal packets.
2. set different pn on rx and tx port, then start the data transfer.
1) set the parameters as test case 1, start and stop the data transfer.
check the result, rx port can receive and decrypt the packets normally.
2) reset the pn of tx port to 0::
testpmd>set macsec sa tx 0 0 0 0 00112200000000000000000000000000
rx port can receive the packets until the pn equals the pn of tx port::
out_pkts_encrypted = in_pkts_late + in_pkts_ok
2. set different keys on rx and tx port, then start the data transfer::
the RX-packets=0,
in_octets_decrypted == out_octets_encrypted,
in_pkts_notvalid == out_pkts_encrypted,
in_pkts_ok=0,
rx_good_packets=0
3. set different pi on rx and tx port(reset on rx_port), then start the data
transfer::
in_octets_decrypted == out_octets_encrypted,
in_pkts_ok = 0,
in_pkts_nosci == out_pkts_encrypted
4. set different an on rx and tx port, then start the data transfer::
rx_good_packets=0,
in_octets_decrypted == out_octets_encrypted,
in_pkts_notusingsa == out_pkts_encrypted,
in_pkts_ok=0,
rx_good_packets=0
5. set different index on rx and tx port, then start the data transfer::
in_octets_decrypted == out_octets_encrypted,
in_pkts_ok == out_pkts_encrypted
Test Case 5: performance test of MACsec offload packets
==========================================================
1. tx linerate
port0 connected to IXIA port5, port1 connected to IXIA port6, set port0
MACsec offload on, set fwd mac.
on IXIA side, start IXIA port6 transmit, start the IXIA capture.
view the IXIA port5 captrued packet, the protocol is MACsec, the EtherType
is 0x88E5, and the packet length is 96bytes, more than the normal packet
32 bytes.
The valid frames received rate is 10.78Mpps, and the %linerate is 100%.
2. rx linerate
there are three ports 05:00.0 07:00.0 07:00.1. connect 07:00.0 to 07:00.1
with cable, connect 05:00.0 to IXIA. bind the three ports to dpdk driver.
start two testpmd::
./testpmd -c 0x3 --socket-mem 1024,1024 --file-prefix=rx -w 0000:07:00.1 \
-- --port-topology=chained -i --crc-strip --txqflags=0x0
testpmd>set macsec offload 0 on encrypt on replay-protect on
testpmd>set macsec sc rx 0 00:00:00:00:00:01 0
testpmd>set macsec sa rx 0 0 0 0 00112200000000000000000000000000
testpmd>set macsec sc tx 0 00:00:00:00:00:02 0
testpmd>set macsec sa tx 0 0 0 0 00112200000000000000000000000000
testpmd>set fwd rxonly
./testpmd -c 0xc --socket-mem 1024,1024 --file-prefix=tx -b 0000:07:00.1 \
-- --port-topology=chained -i --crc-strip --txqflags=0x0
testpmd>set macsec offload 1 on encrypt on replay-protect on
testpmd>set macsec sc rx 1 00:00:00:00:00:02 0
testpmd>set macsec sa rx 1 0 0 0 00112200000000000000000000000000
testpmd>set macsec sc tx 1 00:00:00:00:00:01 0
testpmd>set macsec sa tx 1 0 0 0 00112200000000000000000000000000
testpmd>set fwd mac
start on both two testpmd.
start data transmit from IXIA port, the frame size is 64bytes,
the Ethertype is 0x0800. the rate is 14.88Mpps.
check the linerate on rxonly port::
testpmd>show port stats 0
It shows "Rx-pps: 10775697", so the rx %linerate is 100%.
check the MACsec packets number on tx side::
testpmd>show port xstats 1
on rx side::
testpmd>show port xstats 0
in_pkts_ok == out_pkts_encrypted

I am not sure how that supposed to work and how user should know that DEV_RX_OFFLOAD_RESERVED_0
is actually a MACSEC for ixgbe?
Another question what to do if you would like to create a bonded device over two devices with different NIC types?
As I understand you can end up in situation when DEV_RX_OFFLOAD_RESERVED_0 would mean different capabilities.
Why not to have this MACSEC capability and ol_flag value as generic ones, as you have them in previous versions of your patch?

Users are not supposed to use DEV_RX_OFFLOAD_RESERVED_0, instead, they
should use the capabilities and the likes defined in rte_pmd_ixgbe.h
where the PMD-specifics APIs are declared:
/**
* If these flags are advertised by the PMD, the NIC supports the MACsec
* offload. The incoming MACsec traffics can be offloaded transparently
* after the MACsec offload is configured correctly by the application.
* And the application can set the PKT_TX_IXGBE_MACSEC flag in mbufs to
* enable the MACsec offload for the packets to be transmitted.
*/
#define DEV_RX_OFFLOAD_IXGBE_MACSEC_STRIP DEV_RX_OFFLOAD_RESERVED_0
#define DEV_TX_OFFLOAD_IXGBE_MACSEC_INSERT DEV_TX_OFFLOAD_RESERVED_0
/**
* This event will occur when the PN counter in a MACsec connection
* reach the exhaustion threshold.
*/
#define RTE_ETH_EVENT_IXGBE_MACSEC RTE_ETH_EVENT_RESERVED_0
/**
* Offload the MACsec. This flag must be set by the application in mbuf
* to enable this offload feature for a packet to be transmitted.
*/
#define PKT_TX_IXGBE_MACSEC PKT_TX_RESERVED_0
PMD-specific APIs can only be used on the corresponding driver/device,
so different PMD can share the same reserved bit to represent different
things when implementing their own PMD-specific APIs.

Those flags are only used in PMD-specific APIs. I don't think we could
use the PMD-specific APIs provided by a certain PMD on a bonded device.

Ok, and why do we need it?
Why we can't just have PKT_TX_MACSEC straightway?
What are you trying to gain here?
Is it just for future opportunity to save an extra bit in mbuf.ol_flags?
I don't think we are short of bits here right now, and we don't consume them exra-fast
to start to worry about it.
Again, if it *really* would be for ixgbe only forever, and y don't want to waste a bit in tx_olflags,
why not to introduce device specific ol_flags in mbuf second cache line?
Probably uint16_t would be enough for that.

I understand that.
My question was: suppose user would like to create a bonded device over 2 NICs.
One of them is ixgbe, while other would be some other type.
In future get_dev_info() for each of them might return DEV_RX_OFFLOAD_RESERVED_0 bit as set.
But it would mean completely different thing.
How bonded device would know that to deal properly?
Another example - user has 2 NICs of different type and would like to send the same packet on both of them simultaneously.
As PKT_TX_RESERVED might mean different things for these devices, and user would like to use let say
PKT_TX_IXGBE_MACSEC on one of them, he would need to do a copy of them, instead just increment a refcnt.
Similar issues might arise at RX handling: user got a packet with PKT_RX_RESERVED_0 set.
What does it really mean if there are different NIC types in the system?
The only way to answer that question, as I can see, is to keep track from what NIC that packet was received.
Which I suppose, is not always convenient.

The main purpose is to put the PMD-specific APIs in a separate
namespace instead of mixing the PMD-specific APIs and global APIs
up, and also save the bits in mbuf.ol_flags.
There are other ways to achieve this goal, such as introducing
the PMD specific ol_flags in mbuf second cache line as you said.
I just thought defining some reserved bits seems to be the most
simple way which won't introduce many changes.
What's your suggestions? Should I just revert the changes and
define the generic flags directly?

Yes, that would be my preference.
As I said above - spending extra bit in ol_flags doesn't look like a big problem to me.
In return there would be no need to consider how to handle all that confusing scenarios in future.

Well, I do not agree with Konstantin (no one saw this coming eh?) and do not
think you need to update your series again.
PMD-specific symbols have nothing to do in the global namespace in my
opinion, they are not versioned and may evolve without notice. Neither
applications nor the bonding PMD can rely on them. That's the trade-off.
Therefore until APIs are made global, the safe compromise is to define
neutral, reserved symbols that any PMD can use to implement their own
temporary APIs for testing purposes. These can be renamed later without
changing their value as long as a single PMD uses them.

Hi Adrien,
Thank you very much! :-)
Hi Thomas and Olivier,
I don't have strong opinions here, although I prefer to put
the PMD-specific APIs in a separate namespace. I'd like to
hear or follow your opinions since you are the maintainers
of ethdev and mbuf.
Best regards,

Not sure I do understand your reasoning.
For me MACSEC offload is just one of many HW offloads that we support
and should be treated in exactly the same way.
Applications should be able to use it in a transparent and reliable way,
not only under some limited conditions.
Otherwise what is the point to introduce it at all?
Yes, right now it is supported only by ixgbe PMD, but why that should be the
reason to treat is as second-class citizen?
Let say PKT_TX_TUNNEL_* offloads also are supported only by one PMD right now.

Ok, so what we'll gain by introducing PKT_TX_RESERVED instead of PKT_TX_MACSEC?
As I said in my previous mail the redefinition for the same ol_flag bit (and dev capabilities)
by different PMD might create a lot of confusion in future.
Does the potential saving of 1 bit really worth it?

Well my first reply to this thread was asking why isn't the whole API global
from the start then?
Given there are valid reasons for it not to and no plan to make it so in the
near future, applications must be aware that they are including
rte_pmd_ixgbe.h to use it. That in itself is a limiting condition, right?
> Yes, right now it is supported only by ixgbe PMD, but why that should be the

You are right about PKT_TX_TUNNEL_*, however these flags exist on their own
and are not tied to any API function calls, unlike in this series where
PKT_TX_MACSEC can only be used if the DEV_TX_OFFLOAD_MACSEC_INSERT
capability is present and the whole thing was configured through
rte_pmd_ixgbe_macsec_*() calls after including rte_pmd_ixgbe.h.
To be clear it is not about MACsec per se (as a standardized protocol, I
think related definitions for offloads have their place), but it has to do
with the fact that the rest of the API is PMD-specific and there is a
dependency between them.

That is one benefit, but my point is mainly to keep applications aware that
they are using an API defined by a single PMD, which may be temporary and
whose symbols are not versioned.
Consider this:
rte_mbuf.h:
#define PKT_TX_RESERVED_0 (1 << 42)
rte_pmd_ixgbe.h:
#define PKT_TX_MACSEC PKT_TX_RESERVED_0
That way, applications have to get the PKT_TX_MACSEC definition where the
rest of the API is also defined.
Other PMDs may reuse PKT_TX_RESERVED_0 and other reserved flags to implement
their own experimental APIs.
Applications and the bonding PMD can easily be made aware that such reserved
flags cannot be shared between ports unless they know what the underlying
PMD is, which is already a requirement to use this API in the first place
(for instance, calling rte_pmd_ixgbe_macsec_*() functions with another
vendor's port_id may crash the application).
So the idea if/when the API is made global is to rename PKT_TX_RESERVED_0 to
PKT_TX_MACSEC and keep its original value.
If other PMDs also implemented PKT_TX_RESERVED_0 in the meantime, it is
redefined using a different value. If there is no room left to do so, these
PMDs are out of luck I guess, and their specific API is disabled/removed
until something gets re-designed.
How about this?

That's good question, and my preference would always be to have the
API to configure this feature as generic one.
I guess the main reason why it is not right now we don't reach an agreement
how this API should look like:
http://dpdk.org/ml/archives/dev/2016-September/047810.html
But I'll leave it to the author to provide the real reason here.

Yes, it is definitely a limiting factor.
Though even if API to configure device to use macsec would be PMD specific right now,
The API to query that capability and the API to use it at datapath (mbuf.ol_flags) still
can be (and I think should be) device independent and transparent to use.

I don't think PKT_TX_TUNNEL_* 'exists on its own'.
To use it well behaving app have to:
1) Query that device does provide that capability: DEV_TX_OFFLOAD_*_TNL_TSO
2) configure PMD( & device) to use that capability
3) use that offload at run-time TX code (mb->ol_flags |= ...; mb->tx_offload = ...)
For PKT_TX_TUNNEL_* 2) is pretty simple - user just need to make sure
that full-featured TX function will be selected:
txconf.txq_flags = 0; ...; rte_eth_tx_queue_setup(..., &txconf);
For TX_MACSEC, as I understand 2) will be more complicated and
right now is PMD specific, but anyway the main pattern remains the same.
So at least 1) and 3) could be kept device neutral.

As applications have to use PMD specific functions to configure it they definitely are aware.

That's the main thing I am opposed to.
I think that by allowing PMD to redefine meaning of
mbuf.ol_flags and dev_info.(rx| tx)_offload_capa
we just asking for trouble.
Let say tomorrow, i40e will redefine DEV_TX_OFFLOAD_RESERVED_0 and PKT_TX_RESERVED_0
to implement new specific TX offload (PKT_TX_FEATURE_X).
Now let say we have an application that works over both ixgbe and i40e
and would like to use both TX_MACSEC and TC_FEATURE_X offloads whenever they are available.
As I can see, with the approach you proposed the only way for the application to make it
is to support 2 different TX code paths (or at least some parts of it).
To me that way looks inconvenient to the users and source of future troubles.
Same for RX: somewhere at upper layer user got a packet with PKT_RX_RESERVED_0 set.
What does it really mean if there are different NIC types in the system?

I am talking about that code:
rte_eth_bond_create(const char *name, uint8_t mode, uint8_t socket_id)
{
...
/* Take the first dev's offload capabilities */
internals->rx_offload_capa = dev_info.rx_offload_capa;
internals->tx_offload_capa = dev_info.tx_offload_capa;
...
internals->rx_offload_capa &= dev_info.rx_offload_capa;
internals->tx_offload_capa &= dev_info.tx_offload_capa;
Obviously with what you are suggesting it is not valid any more.
Bonded device need to support a MASK of all device reserved offloads to exclude
them from common subset.
Any user app(/lib) that does similar thing would also have to be changed.

I still think that we shouldn't allow PMDs to redefine mbuf.olflags and
dev_info.(rx|tx)_offload_capa.
See above for my reasons.

Yes, currently this work just provided a thin layer over 82599's
hardware MACsec offload support to allow users configure 82599's
MACsec offload engine. The current API may be too specific and may
need a rework to be used with other NICs.

Yes, the PMD-specific APIs focus on the 2nd step:
2) configure PMD( & device) to use that capability
The other parts (querying the capabilities, using the offload
in the datapath, registering the callback, getting the statistics
via xstats) are done in generic way.

I think it is a really good approach to start such API privately in a driver.
It will give us more time and experience to design a proper generic API.
Regarding the mbuf flag, it looks straight-forward, and as it is IEEE
standardized, I do not see any objection to add it now.
However, I will wait for the approval of Olivier - as maintainer of mbuf.

With RESERVED flags, what is global and transparent is the fact the mbuf or
device features in question are PMD-specific and some extra knowledge about
the underlying port is necessary to handle them. I think that could be
useful to applications in order to get the necessary precautions.

Pretty much like any other offloads. Any PMD could implement them as well
without exposing additional callbacks.

Yes, however this discussion is precisely because I think it could be a
problem that this API "right now is PMD specific", particularly because it
will remain that way.

Therefore they also know if they are only running on top of ixgbe adapters
of a mix with something else. By choosing the PMD-specific path, they know
what they are getting into.

Remember applications still have to clear PKT_TX_MACSEC and other flags on
ports that do not implement them, just like when the related offload is not
configured even if supported. Whichever approach is taken, applications have
to be careful and need a few extra checks in their TX path. There is no
extra cost involved compared to existing offloads.

For RX, I agree things are more complicated, applications would have to know
what a given flag means from a particular port. We could define several
RESERVED_X flags that do not overlap on a case basis, so at least
applications know they are dealing with PMD-specific flags.

Why can't they clear RESERVED flags as well? We just have to document the
expected behavior. Even if the bonding PMD does not, applications that do
not use those flags (since they are reserved) should not be impacted.
Because the bonding PMD won't forward PMD-specific API calls, I think it's
safer to clear them anyway.
By the way, how do you handle the case where the bonding PMD exposes the
MACSEC feature and as a result the application tries to configure MACSEC
support on the bonding port_id? How is the resulting crash documented in a
generic fashion?

I'm still not comfortable with partially global/specific APIs such as this,
because we assume applications are fully aware of the underlying port in
order to use them, while at the same time the related flags are part of the
global namespace, I find it confusing.
If application developers have no problem with that (so far they haven't
commented on this topic, which means they likely agree to go with anything),
I have no reason left to go against the majority.

This commit adds a below event type:
- RTE_ETH_EVENT_MACSEC
This event will occur when the PN counter in a MACsec connection
reaches the exhaustion threshold.

If these flags are advertised by a PMD, the NIC supports the MACsec
offload. The incoming MACsec traffics can be offloaded transparently
after the MACsec offload is configured correctly by the application.
And the application can set the PKT_TX_MACSEC flag in mbufs to enable
the MACsec offload for the packets to be transmitted.

MACsec (or LinkSec, 802.1AE) is a MAC level encryption/authentication
scheme defined in IEEE 802.1AE that uses symmetric cryptography.
This commit adds the MACsec offload support for ixgbe.

Below MACsec offload commands are added:
- set macsec offload <port_id> on encrypt on|off replay-protect on|off
- set macsec offload <port_id> off
- set macsec sc tx|rx <port_id> <mac> <pi>

Generally speaking, we have to be careful when introducing new mbuf
flags, since we don't have so much of them (~25 remaining out of 64,
which mean we may run out of them in 3-4 years).
In this particular case, despite the flag is added for an ixgbe-specific
API, when MACsec will be implemented on another PMD, the exact same
flag would also be needed. That's the same for the ethdev capability
flag. Moreover, as Thomas stated, it's a standardized protocol so it's
legitimate to have it included in rte_mbuf.h.
For me, having PMD-specific APIs for a new feature is not a problem,
but I think we should try to have a generic API as soon as the feature
is supported by several PMDs.

Olivier

JFYI, here is how the virtio handle the feature bits. It basically
just divides it to two parts.
>From virtio 1.0 spec (2.2 Feature Bits):
Feature bits are allocated as follows:
- 0 to 23 Feature bits for the specific device type
- 24 to 32 Feature bits reserved for extensions to the queue and feature
negotiation mechanisms
- 33 and above Feature bits reserved for future extensions.
Note: For example, feature bit 0 for a network device (i.e. Device ID 1)
indicates that the device supports checksumming of packets.

If these flags are advertised by a PMD, the NIC supports the MACsec
offload. The incoming MACsec traffics can be offloaded transparently
after the MACsec offload is configured correctly by the application.
And the application can set the PKT_TX_MACSEC flag in mbufs to enable
the MACsec offload for the packets to be transmitted.

Below MACsec offload commands are added:
- set macsec offload <port_id> on encrypt on|off replay-protect on|off
- set macsec offload <port_id> off
- set macsec sc tx|rx <port_id> <mac> <pi>
- set macsec sa tx|rx <port_id> <idx> <an> <pn> <key>
Also update the testpmd user guide.

- version: 17.02-rc1
- OS/Kernel: 4.5.5-300.fc24.x86_64
- GCC: gcc (GCC) 5.3.1 20151207 (Red Hat 5.3.1-2)
- NIC: 82599
Test cases: 5
Passed: 5
Test steps:
Test Case 1: MACsec packets send and receive
============================================
1. connect the two ixgbe ports with a cable,
and bind the two ports to dpdk driver::
./tools/dpdk-devbind.py -b igb_uio 07:00.0 07:00.1
2. config the rx port
1). start the testpmd of rx port::
./testpmd -c 0xc --socket-mem 1024,1024 --file-prefix=rx -w 0000:07:00.1 \
-- --port-topology=chained -i --crc-strip
2). set MACsec offload on::
testpmd>set macsec offload 0 on encrypt on replay-protect on
3). set MACsec parameters as rx_port::
testpmd>set macsec sc rx 0 00:00:00:00:00:01 0
testpmd>set macsec sa rx 0 0 0 0 00112200000000000000000000000000
4). set MACsec parameters as tx_port::
testpmd>set macsec sc tx 0 00:00:00:00:00:02 0
testpmd>set macsec sa tx 0 0 0 0 00112200000000000000000000000000
5). set rxonly::
testpmd>set fwd rxonly
6). start::
testpmd>set promisc all on
testpmd>start
3. config the tx port
1). start the testpmd of tx port::
./testpmd -c 0x30 --socket-mem 1024,1024 --file-prefix=tx -w 0000:07:00.0 \
-- --port-topology=chained -i --crc-strip --txqflags=0x0
2). set MACsec offload on::
testpmd>set macsec offload 0 on encrypt on replay-protect on
3). set MACsec parameters as tx_port::
testpmd>set macsec sc tx 0 00:00:00:00:00:01 0
testpmd>set macsec sa tx 0 0 0 0 00112200000000000000000000000000
4). set MACsec parameters as rx_port::
testpmd>set macsec sc rx 0 00:00:00:00:00:02 0
testpmd>set macsec sa rx 0 0 0 0 00112200000000000000000000000000
5). set txonly::
testpmd>set fwd txonly
6). start::
testpmd>start
4. check the result::
testpmd>stop
testpmd>show port xstats 0
stop the packet transmiting on tx_port first, then stop the packet receiving
on rx_port.
check the rx data and tx data:
tx_good_packets == rx_good_packets
out_pkts_encrypted == in_pkts_ok == tx_good_packets == rx_good_packets
out_octets_encrypted == in_octets_decrypted
out_octets_protected == in_octets_validated
if you want to check the content of the packet, use the command::
testpmd>set verbose 1
the received packets are Decrypted.
check the ol_flags:PKT_RX_IP_CKSUM_GOOD
check the content of the packet:
type=0x0800, the ptype of L2,L3,L4: L2_ETHER L3_IPV4 L4_UDP
Test Case 2: MACsec packets send and normal receive
===================================================
1. disable MACsec offload on rx port::
testpmd>set macsec offload 0 off
2. start the the packets transfer
3. check the result::
testpmd>stop
testpmd>show port xstats 0
stop the testpmd on tx_port first, then stop the testpmd on rx_port.
the received packets are encrypted.
check the content of the packet:
type=0x88e5 sw ptype: L2_ETHER - l2_len=14 - Receive queue=0x0
you can't find L3 and L4 infomation in the packet
in_octets_decrypted and in_octets_validated doesn't increase on last data
transfer.
Test Case 3: normal packet send and MACsec receive
==================================================
1. enable MACsec offload on rx port::
testpmd>set macsec offload 0 on encrypt on replay-protect on
2. disable MACsec offload on tx port::
testpmd>set macsec offload 0 off
3. start the the packets transfer
4. check the result::
testpmd>stop
testpmd>show port xstats 0
stop the testpmd on tx_port first, then stop the testpmd on rx_port.
the received packets are not encrypted.
check the content of the packet:
type=0x0800, the ptype of L2,L3,L4: L2_ETHER L3_IPV4 L4_UDP
in_octets_decrypted and out_pkts_encrypted doesn't increase on last data
transfer.
Test Case 4: MACsec send and receive with wrong parameters
==========================================================
1. don't add "--txqflags=0x0" in the tx_port command line.
the MACsec offload can't work. the tx packets are normal packets.
2. set different pn on rx and tx port, then start the data transfer.
1) set the parameters as test case 1, start and stop the data transfer.
check the result, rx port can receive and decrypt the packets normally.
2) reset the pn of tx port to 0::
testpmd>set macsec sa tx 0 0 0 0 00112200000000000000000000000000
rx port can receive the packets until the pn equals the pn of tx port::
out_pkts_encrypted = in_pkts_late + in_pkts_ok
3. set different keys on rx and tx port, then start the data transfer::
the RX-packets=0,
in_octets_decrypted == out_octets_encrypted,
in_pkts_notvalid == out_pkts_encrypted,
in_pkts_ok=0,
rx_good_packets=0
4. set different pi on rx and tx port(reset on rx_port), then start the data
transfer::
in_octets_decrypted == out_octets_encrypted,
in_pkts_ok = 0,
in_pkts_nosci == out_pkts_encrypted
5. set different an on rx and tx port, then start the data transfer::
rx_good_packets=0,
in_octets_decrypted == out_octets_encrypted,
in_pkts_notusingsa == out_pkts_encrypted,
in_pkts_ok=0,
rx_good_packets=0
6. set different index on rx and tx port, then start the data transfer::
in_octets_decrypted == out_octets_encrypted,
in_pkts_ok == out_pkts_encrypted
Test Case 5: performance test of MACsec offload packets
==========================================================
1. tx linerate
port0 connected to IXIA port5, port1 connected to IXIA port6, set port0
MACsec offload on, set fwd mac::
./x86_64-native-linuxapp-gcc/app/testpmd -c 0xc -- -i \
--port-topology=chained --crc-strip --txqflags=0x0
on IXIA side, start IXIA port6 transmit, start the IXIA capture.
view the IXIA port5 captrued packet, the protocol is MACsec, the EtherType
is 0x88E5, and the packet length is 96bytes, more than the normal packet
32 bytes.
The valid frames received rate is 10.78Mpps, and the %linerate is 100%.
2. rx linerate
there are three ports 05:00.0 07:00.0 07:00.1. connect 07:00.0 to 07:00.1
with cable, connect 05:00.0 to IXIA. bind the three ports to dpdk driver.
start two testpmd::
./testpmd -c 0x3 --socket-mem 1024,1024 --file-prefix=rx -w 0000:07:00.1 \
-- --port-topology=chained -i --crc-strip --txqflags=0x0
testpmd>set macsec offload 0 on encrypt on replay-protect on
testpmd>set macsec sc rx 0 00:00:00:00:00:01 0
testpmd>set macsec sa rx 0 0 0 0 00112200000000000000000000000000
testpmd>set macsec sc tx 0 00:00:00:00:00:02 0
testpmd>set macsec sa tx 0 0 0 0 00112200000000000000000000000000
testpmd>set fwd rxonly
./testpmd -c 0xc --socket-mem 1024,1024 --file-prefix=tx -b 0000:07:00.1 \
-- --port-topology=chained -i --crc-strip --txqflags=0x0
testpmd>set macsec offload 1 on encrypt on replay-protect on
testpmd>set macsec sc rx 1 00:00:00:00:00:02 0
testpmd>set macsec sa rx 1 0 0 0 00112200000000000000000000000000
testpmd>set macsec sc tx 1 00:00:00:00:00:01 0
testpmd>set macsec sa tx 1 0 0 0 00112200000000000000000000000000
testpmd>set fwd mac
start on both two testpmd.
start data transmit from IXIA port, the frame size is 64bytes,
the Ethertype is 0x0800. the rate is 14.88Mpps.
check the linerate on rxonly port::
testpmd>show port stats 0
It shows "Rx-pps: 10775697", so the rx %linerate is 100%.
check the MACsec packets number on tx side::
testpmd>show port xstats 1
on rx side::
testpmd>show port xstats 0
in_pkts_ok == out_pkts_encrypted
Thank you.
Yuan.

Subject: [dpdk-dev] [PATCH v7 0/6] Add MACsec offload support for ixgbe
This patch set adds the MACsec offload support for ixgbe.
The testpmd is also updated to support MACsec cmds.
v2:
- Update the documents for testpmd;
- Update the release notes;
- Reuse the functions provided by base code;
v3:
- Add the missing parts of MACsec mbuf flag and reorganize the patch set;
- Add an ethdev event type for MACsec;
- Advertise the MACsec offload capabilities based on the mac type;
- Minor fixes and improvements;
v4:
- Reserve bits in mbuf and ethdev for PMD specific API;
- Use the reserved bits in PMD specific API;
v5:
- Add MACsec offload in the NIC feature list;
- Minor improvements on comments;
v6:
- Revert the changes related to the reserved flags;
- Rebase the patch set on the latest branch, xstats code is changed recently;
- Update the feature list when adding the MACsec support for ixgbe;
v7:
- Fix clang build;
