Right, on the other hand there are not that many standard encapsulations
offloaded by existing devices. rte_flow could easily handle dedicated
actions for each of them without problem.
My point is that many of those (will eventually) have their own quirks to
manage when doing encap/decap, it's not just a matter of prepending or
removing a bunch of header definitions, otherwise we could as well let
applications simply provide an arbitrary buffer to prepend.
Consider that the "generic" part is already built into rte_flow as the way
patterns and action are handled. Adding another generic layer on top of that
could make things more inconvenient than necessary to applications (my main
concern).
You'd need another layer of validation/error reporting machinery to properly
let applications know they cannot encap VXLAN on top of TCP on top of
QinQinQinQinQ for instance. Either a single bounded encapsulation definition
or a combination at the action list level is needed to avoid that.

Well, the number of DECAP actions doesn't need to perfectly reflect that of
ENCAP since it implies all preceding layers. No problem with that.
Regarding multiple dedicated actions, my suggestion was for a single generic
one as in this patch, but each instance on the ENCAP side would deal with a
single protocol layer, instead of having a single ENCAP action with multiple
inner layers (and thus an inner loop).
PMDs also gain the ability to precisely report which encap step fails by
making rte_flow_error point to the problematic object to ease debugging of
flow rules on the application side.
Why would that break the tunnel idea and more importantly, how would it
prevent PMD developers from splitting their processing into multiple
functions?

Right, I noticed that after commenting its structure definition below.
I think I won't be the only one confused by this approach, also because a
mask is needed in addition to a specification structure, otherwise how do
you plan to tell what fields are relevant in application-provided protocol
headers?
An application might set unusual IPv4/UDP/VXLAN fields and expect them to be
part of the encapsulated traffic. Without a mask, a PMD must take headers
verbatim, and I don't think many devices are ready for that yet.
Hence my other suggestion: defining inflexible $PROTOCOL_(ENCAP|DECAP)
actions that do not allow more than what's defined by official RFCs for
$PROTOCOL.

Point still stands, if you need to distinguish spec and mask, a more
complete structure is needed. Instead of adding a new (confusing) type, you
should use rte_flow_item and define what happens when "last" is set.
You should define it as reserved for now, any non-NULL value is an
error. This field might also be useful later.

Yep, that's fine, whether we use multiple actions or a single one doing
multiple things, a single DECAP can peel them off all at once :)

If the reasons I gave did not manage to convince you about choosing between
either fixed (VLAN|VXLAN)_(ENCAP|DECAP) actions or generic encap/decap
actions that deal with a single protocol layer at once instead of the
proposed approach, I'm ready to try it out as an experimental API (all new
objects tagged as experimental) *if* you address the lack of mask, which
remains an open issue.

The ENCAP/DECAP doesn't have to be in the context of tunnel.
For example - let's take GRE - application may want to decap the GRE and encap it with L2. The L2 encapsulation is not related to any tunnel.
Same for the other direction - VM sends Eth frame, and we want to decap the Eth and encap with GRE.
I think those action should be free from the tunnel association and just provide flow items we want to encap/decap or in a more generic way offset to the packet headers and buffer to encap (not sure how many devices supports that, may be overkill at this point).

Why not make the hash_func pointer in the rte_hash_parameters structure an
anonymous union, and reserve a bit in the extra_flag field to denote if the
function pointer has 3 arguments or 4? Then rte_hash_hash can use the
appropriate calling convention on hash_func.

Agree that this solution is a lot better than raw casting.
The issue I have with casting is that it doesn't explicitly show that the signature is different, and that the code must be aware of that fact. With a union, at least the code explicitly states that there is a difference in signature, and that this is being handled by the code, so this looks a better solution.
Neil proposed an alternative solution using a bit to indicate calling params in a separate reply - another possibility.

This change is OK with me, from what I can see using cpuinfo_cur_freq
instead of
scaling_cpu_freq gives us more compatibility on a wider selection of
operating systems.

I see here you are calling guest_channel_host_connect to "emulate" a
virtio-serial connection
to a host. While I am not a huge fan of faking functionality, I feel
that having these unit tests
check ABI and API breakages is more beneficial, so I'm good with it for
this reason.
However, there's no need to have the power_kvm_vm_enable/disable_turbo()
prototypes, as you
can just use rte_power_freq_enable_turbo() and
rte_power_freq_disable_turbo(), which in turn
call power_kvm_vm_enable_turbo() and power_kvm_vm_disable_turbo()

* [dpdk-dev] [PATCH v3 00/16] Flow API overhaul for switch offloads
@ 2018-04-10 16:36 4% ` Adrien Mazarguil
2018-04-10 16:36 3% ` [dpdk-dev] [PATCH v3 01/16] ethdev: add error types to flow API Adrien Mazarguil

To: Thomas Monjalon, Ferruh Yigit, dev
As summarized in a prior RFC [1], the flow API (rte_flow) was chosen as a
means to manage switch offloads supported by many devices (usually going by
names such as E-Switch or vSwitch) through user-specified flow rules.
Combined with the need to support encap/decap actions, this requires a
change in the way flow actions are processed (in order and possibly
repeated) which modifies the behavior of some of the existing actions, thus
warranting a major ABI breakage.
Given this ABI breakage is also required by other work submitted for the
current release [2][3], this series addresses various longstanding issues
with the flow API and makes minor improvements in preparation for upcoming
features.
Changes summary:
- Additional error types.
- Clearer documentation.
- Improved C++ compatibility.
- Exhaustive RSS action.
- Consistent behavior of VLAN pattern item.
- New "transfer" attribute bringing consistency to VF/PF pattern items.
- Confusing "PORT" pattern item renamed "PHY_PORT", with new action
counterpart.
- New "PORT_ID" pattern item and action to be used with port representors.
This series piggybacks on the major ABI update introduced by a prior
commit [4] for DPDK 18.05 and depends on several fixes [5] which must be
applied first.
[1] "[RFC] Switch device offload with DPDK"
http://dpdk.org/ml/archives/dev/2018-March/092513.html
[2] commit 676b605182a5 ("doc: announce ethdev API change for RSS
configuration")
[3] "[PATCH v1 00/21] MLX5 tunnel Rx offloading"
http://dpdk.org/ml/archives/dev/2018-March/092264.html
[4] commit 653e038efc9b ("ethdev: remove versioning of filter control
function")
[5] "[PATCH v4 00/11] Bunch of flow API-related fixes"
http://dpdk.org/ml/archives/dev/2018-April/096509.html
v3 changes:
- Rebased series, fixed latest conflicts.
- Addressed Andrew's comments, see affected patches for details:
- Empty RSS types in flow rule means PMD-specific RSS instead of no RSS.
- RSS hash function now explicitly compared against
RTE_ETH_HASH_FUNCTION_DEFAULT instead of 0 in all PMDs.
- sfc PMD updated to also accept Toeplitz.
- Implicit VLAN TPID matching now removed from all PMDs.
- Default mask upate for VLAN TCI now split as separate patch #11.
- Ingress/egress definition clarified in patch #12.
v2 changes:
- Squashed "ethdev: update ABI for flow API functions" in subsequent
patches.
- Emphasized ABI impact in relevant commit logs.
- Modified documentation in "ethdev: alter behavior of flow API actions" to
describe how terminating flow rules without any action of the fate kind
result in undefined behavior instead of dropping traffic.
- Fixed other minor documentation formatting issues.
- Modified "ethdev: refine TPID handling in flow API" as follows:
- Using standard macro definitions for VLAN, QinQ and E-Tag EtherTypes.
- Fixed endian conversion in sfc.
- Replaced a condition in VLAN pattern item processing with an assertion
check for i40e.

These enable more precise reporting of objects responsible for errors.
This breaks ABI compatibility for the following public functions:
- rte_flow_create()
- rte_flow_destroy()
- rte_flow_error_set()
- rte_flow_flush()
- rte_flow_isolate()
- rte_flow_query()
- rte_flow_validate()

Upcoming changes in relation to the handling of actions list will make the
DUP action redundant as specifying several QUEUE actions will achieve the
same behavior. Besides, no PMD implements this action.
By removing an entry from enum rte_flow_action_type, this patch breaks ABI
compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

This patch makes the following changes to flow rule actions:
- List order now matters, they are redefined as performed first to last
instead of "all simultaneously".
- Repeated actions are now supported (e.g. specifying QUEUE multiple times
now duplicates traffic among them). Previously only the last action of
any given kind was taken into account.
- No more distinction between terminating/non-terminating/meta actions.
Flow rules themselves are now defined as always terminating unless a
PASSTHRU action is specified.
These changes alter the behavior of flow rules in corner cases in order to
prepare the flow API for actions that modify traffic contents or properties
(e.g. encapsulation, compression) and for which order matter when combined.
Previously one would have to do so through multiple flow rules by combining
PASSTRHU with priority levels, however this proved overly complex to
implement at the PMD level, hence this simpler approach.
This breaks ABI compatibility for the following public functions:
- rte_flow_create()
- rte_flow_validate()
PMDs with rte_flow support are modified accordingly:
- bnxt: no change, implementation already forbids multiple actions and does
not support PASSTHRU.
- e1000: no change, same as bnxt.
- enic: modified to forbid redundant actions, no support for default drop.
- failsafe: no change needed.
- i40e: no change, implementation already forbids multiple actions.
- ixgbe: same as i40e.
- mlx4: modified to forbid multiple fate-deciding actions and drop when
unspecified.
- mlx5: same as mlx4, with other redundant actions also forbidden.
- sfc: same as mlx4.
- tap: implementation already complies with the new behavior except for
the default pass-through modified as a default drop.

From: Adrien Mazarguil @ 2018-04-10 16:36 UTC (permalink / raw)
To: Thomas Monjalon, Ferruh Yigit, dev
This patch replaces C99-style flexible arrays in struct rte_flow_action_rss
and struct rte_flow_item_raw with standard pointers to the same data.
They proved difficult to use in the field (e.g. no possibility of static
initialization) and unsuitable for C++ applications.
Affected PMDs and examples are updated accordingly.
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

Since its inception, the rte_flow RSS action has been relying in part on
external struct rte_eth_rss_conf for compatibility with the legacy RSS API.
This structure lacks parameters such as the hash algorithm to use, and more
recently, a method to tell which layer RSS should be performed on [1].
Given struct rte_eth_rss_conf will never be flexible enough to represent a
complete RSS configuration (e.g. RETA table), this patch supersedes it by
extending the rte_flow RSS action directly.
A subsequent patch will add a field to use a non-default RSS hash
algorithm. To that end, a field named "types" replaces the field formerly
known as "rss_hf" and standing for "RSS hash functions" as it was
confusing. Actual RSS hash function types are defined by enum
rte_eth_hash_function.
This patch updates all PMDs and example applications accordingly.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

configuration")

v3 changes:
Documentation update regarding the meaning of a 0 value for RSS types in
flow rules.
It used to implicitly mean "no RSS" but is redefined as requesting a kind
of "best-effort" mode from PMDs, i.e. anything ranging from empty to
all-inclusive RSS; what matters is it provides safe defaults that will work
regardless of PMD capabilities.

Similar to QUEUE, except RSS is additionally performed on packets to spread
them among several queues according to the provided parameters.

+unspecified "best-effort" settings from the underlying PMD, which depending

By definition, RSS involves some kind of hash algorithm, usually Toeplitz.
Until now it could not be modified on a flow rule basis and PMDs had to
always assume RTE_ETH_HASH_FUNCTION_DEFAULT, which remains the default
behavior when unspecified (0).
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

v3 changes:
- Although RTE_ETH_HASH_FUNCTION_DEFAULT is defined as 0, made comparisons
more explicit where doing so would clarify the code.
- Updated sfc to include Toeplitz as the other allowed value.
Both according to Andrew's suggestions [1].

RSS hash types (ETH_RSS_* macros defined in rte_ethdev.h) describe the
protocol header fields of a packet that must be taken into account while
computing RSS.
When facing encapsulated (e.g. tunneled) packets, there is an ambiguity as
to whether these should apply to inner or outer packets. Applications need
the ability to tell exactly "where" RSS must be performed.
This is addressed by adding encapsulation level information to the RSS flow
action. Its default value is 0 and stands for the usual unspecified
behavior. Other values provide a specific encapsulation level.
Contrary to the change announced by commit 676b605182a5 ("doc: announce
ethdev API change for RSS configuration"), this patch does not affect
struct rte_eth_rss_conf but struct rte_flow_action_rss as the former is not
used anymore by the RSS flow action. ABI impact is therefore limited to
rte_flow.
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

TPID handling in rte_flow VLAN and E_TAG pattern item definitions is not
consistent with the normal stacking order of pattern items, which is
confusing to applications.
Problem is that when followed by one of these layers, the EtherType field
of the preceding layer keeps its "inner" definition, and the "outer" TPID
is provided by the subsequent layer, the reverse of how a packet looks like
on the wire:
Wire: [ ETH TPID = A | VLAN EtherType = B | B DATA ]
rte_flow: [ ETH EtherType = B | VLAN TPID = A | B DATA ]
Worse, when QinQ is involved, the stacking order of VLAN layers is
unspecified. It is unclear whether it should be reversed (innermost to
outermost) as well given TPID applies to the previous layer:
Wire: [ ETH TPID = A | VLAN TPID = B | VLAN EtherType = C | C DATA ]
rte_flow 1: [ ETH EtherType = C | VLAN TPID = B | VLAN TPID = A | C DATA ]
rte_flow 2: [ ETH EtherType = C | VLAN TPID = A | VLAN TPID = B | C DATA ]
While specifying EtherType/TPID is hopefully rarely necessary, the stacking
order in case of QinQ and the lack of documentation remain an issue.
This patch replaces TPID in the VLAN pattern item with an inner
EtherType/TPID as is usually done everywhere else (e.g. struct vlan_hdr),
clarifies documentation and updates all relevant code.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()
Summary of changes for PMDs that implement ETH, VLAN or E_TAG pattern
items:
- bnxt: EtherType matching is supported with and without VLAN, but TPID
matching is not and triggers an error.
- e1000: EtherType matching is only supported with the ETHERTYPE filter,
which does not support VLAN matching, therefore no impact.
- enic: same as bnxt.
- i40e: same as bnxt with existing FDIR limitations on allowed EtherType
values. The remaining filter types (VXLAN, NVGRE, QINQ) do not support
EtherType matching.
- ixgbe: same as e1000, with additional minor change to rely on the new
E-Tag macro definition.
- mlx4: EtherType/TPID matching is not supported, no impact.
- mlx5: same as bnxt.
- mvpp2: same as bnxt.
- sfc: same as bnxt.
- tap: same as bnxt.

v3 changes:
Updated mrvl to mvpp2.
Moved unrelated default TCI mask update to separate patch.
Fixed sfc according to Andrew's comments [1], which made so much sense that
I standardized on the same behavior for all other PMDs: matching outer TPID
is never supported when a VLAN pattern item is present.
This is done because many devices accept several TPIDs but do not provide
means to match a given one explicitly, it's all or nothing, and that makes
the resulting flow rule inaccurate.

To: Thomas Monjalon, Ferruh Yigit, dev; +Cc: Andrew Rybchenko
This new attribute enables applications to create flow rules that do not
simply match traffic whose origin is specified in the pattern (e.g. some
non-default physical port or VF), but actively affect it by applying the
flow rule at the lowest possible level in the underlying device.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_validate()
Signed-off-by: Adrien Mazarguil <adrien.mazarguil@6wind.com>
Cc: Andrew Rybchenko <arybchenko@solarflare.com>

v3 changes:
Clarified definition for ingress and egress following Andrew's comment on
subsequent patch.

Specifying both directions at once for a given rule is not recommended but
may be valid in a few cases (e.g. shared counters).
+Attribute: Transfer
+^^^^^^^^^^^^^^^^^^^
+
+Instead of simply matching the properties of traffic as it would appear on a
+given DPDK port ID, enabling this attribute transfers a flow rule to the
+lowest possible level of any device endpoints found in the pattern.
+
+When supported, this effectively enables an application to reroute traffic
+not necessarily intended for it (e.g. coming from or addressed to different
+physical ports, VFs or applications) at the device level.
+
+It complements the behavior of some pattern items such as `Item: PORT`_ and
+is meaningless without them.
+
+When transferring flow rules, **ingress** and **egress** attributes
+(`Attribute: Traffic direction`_) keep their original meaning, as if
+processing traffic emitted or received by the application.

Contrary to all other pattern items, these are inconsistently documented as
affecting traffic instead of simply matching its origin, without provision
for the latter.
This commit clarifies documentation and updates PMDs since the original
behavior now has to be explicitly requested using the new transfer
attribute.
It breaks ABI compatibility for the following public functions:
- rte_flow_create()
- rte_flow_validate()
Impacted PMDs are bnxt and i40e, for which the VF pattern item is now only
supported when a transfer attribute is also present.

While RTE_FLOW_ITEM_TYPE_PORT refers to physical ports of the underlying
device using specific identifiers, these are often confused with DPDK port
IDs exposed to applications in the global name space.
Since this pattern item is seldom used, rename it RTE_FLOW_ITEM_PHY_PORT
for better clarity.
No ABI impact.

This patch adds the missing action counterpart to the PHY_PORT pattern
item, that is, the ability to directly inject matching traffic into a
physical port of the underlying device.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

RTE_FLOW_ACTION_TYPE_PORT_ID brings the ability to inject matching traffic
into a different device, as identified by its DPDK port ID.
This is normally only supported when the target port ID has some kind of
relationship with the port ID the flow rule is created against, such as
being exposed by a common physical device (e.g. a different port of an
Ethernet switch).
The converse pattern item, RTE_FLOW_ITEM_TYPE_PORT_ID, makes the resulting
flow rule match traffic whose origin is the specified port ID. Note that
specifying a port ID that differs from the one the flow rule is created
against is normally meaningless (if even accepted), but can make sense if
combined with the transfer attribute.
These must not be confused with their PHY_PORT counterparts, which refer to
physical ports using device-specific indices, but unlike PORT_ID are not
necessarily tied to DPDK port IDs.
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

This patch provides the same functionality and supersedes Qi Zhang's
"ether: add flow action to redirect packet to a port" [1].
The main differences are:
- Action is named PORT_ID instead of PORT.
- Addition of a PORT_ID pattern item.
- More extensive documentation.
- Testpmd support.
- rte_flow_copy() support.

But just to make HW to RX multiple packets into one mbuf,
data_off inside indirect mbuf should be enough, correct?
As I understand, what you'd like to achieve with this new field -
ability to manipulate packet boundaries after RX, probably at upper layer.
As Olivier pointed above, that doesn't sound as safe approach - as you have multiple
indirect mbufs trying to modify same direct buffer.
Though if you really need to do that, why it can be achieved by updating buf_len and priv_size
Fields for indirect mbufs, straight after attach()?

Even though those fields are read only in fastpath,I suppose moving all
the fields(used in fast path) after prod, prefetch _cons_ cache line in cross
CPU case.
I think, following comment can be addressed in code as it is an ABI change.
/*
* Note: this field kept the RTE_MEMZONE_NAMESIZE size due to
* ABI
* compatibility requirements, it could be changed to
* RTE_RING_NAMESIZE
* next time the ABI changes
*/
char name[RTE_MEMZONE_NAMESIZE] __rte_cache_aligned; /**< Name of the ring. */

Right. Current max buffer len of mbuf is 64kB (16bits) but it is enough for mlx5
to reach to 100Gbps with 64B traffic (149Mpps). I made mlx5 HW put 16 packets in
a buffer. So, it needs ~32kB buffer. Having more bits in length fields would be
better but 16-bit is good enough to overcome the PCIe Gen3 bottleneck in order
to saturate the network link.

I agree that there's an implication that indirect mbuf or mbuf having refcnt > 1
is read-only. What that means, all the entities which own such mbufs have to be
aware of that and keep the principle as DPDK can't enforce the rule and there
can't be such sanity check. In this sense, HW doesn't violate it because the
direct mbuf is injected to HW before indirection. When packets are written by
HW, PMD attaches indirect mbufs to the direct mbuf and deliver those to
application layer with freeing the original direct mbuf (decrement refcnt by 1).
So, HW doesn't touch the direct buffer once it reaches to upper layer. The
direct buffer will be freed and get available for reuse when all the attached
indirect mbufs are freed.

Good point.
Actually that was my draft (Mellanox internal) version of this patch :-) But I
had to consider a case where priv_size is really given by user. Even though it
is less likely, but if original priv_size is quite big, it can't cover entire
buf_len. For this, I had to increase priv_size to 32-bit but adding another
16bit field (buf_off) looked more plausible.

Adding a new rte_flow pattern item in the middle of enum rte_flow_item_type
breaks ABI compatibility. It's fine for 18.05 because prior series already
destroyed it, however for this patch you need to choose between:
- Adding the new entry at the end of the enum and modifying the rest of the
code to follow the same order (preferred approach when not doing a full
API overhaul).
*or*
- Stating in the commit log what functions are impacted by ABI changes as in
"ethdev: remove DUP action from flow API" [1].
Also you must add a new "Item: ``VXLAN_GPE``" section to
doc/guides/prog_guide/rte_flow.rst (look for "VXLAN" for clues).
Otherwise patch is mostly fine, just a few comments below.

Again if you choose to not impact ABI, this should be moved further down,
after the last item definition for consistency.

Depending on whether you chose to impact ABI compatibility in the second
patch of the series, you may need to reorder all VXLAN_GPE definitions in
this patch to match that of the rte_flow API.

You need to update the "Pattern items" section of the flow command

There were few complains that 64KB max is a limitation for some use-cases.
I am not against increasing it, but I don't think we have free space on first cache-line for that
without another big rework of mbuf layout.
Considering that we need to increase size for buf_len, data_off, data_len, and probably priv_size too.

Yes, I understand that. But as I can see you introduced functions to adjust head and tail,
which implies that it should be possible by some entity (upper layer?) to manipulate these
indirect mbufs.
And we don't know how exactly it will be done.

As I remember, we can't have mbufs bigger then 64K,
so priv_size + buf_len should be always less than 64K, correct?

testpmd is not the only application. But in any case I agree that it was
possible have rss_hf==0 before. So, no big changes.

PMD-specific is fine with some limits. It should be either device RSS
config or
device defaults. I think it is bad idea to allow types=0 disable RSS as
an option
of the PMD-specific behaviour.

Please confirm whether existing devices have the ability to report time
elapsed since last hit, or if PMDs are supposed to take care of that
entirely on their own in software?
If the latter, I suggest to drop this patch and let applications check
counters regularly on their own. Unlike applications, PMDs do not easily
have access to a reliable time source.
Otherwise, the patch looks acceptable but I can't tell if milliseconds are
the right unit for such information. Same issue as mbuf timestamps [1]
basically. As a 64-bit field, a precision down to the nanosecond is a
possibility so perhaps like mbufs, the reference and precision should be
undefined in the API in order to be processed by a PMD callback?
More comments below.

You need to decrement reserved bits.

Doing so impacts ABI compatibility. While normally frowned upon for
rte_flow, it's OK for 18.05 because we already destroyed it. You still need
to mention what functions are impacted by this change as in "ethdev: add
encap level to RSS flow API action" [2] and update the .map files where
necessary.
In this case at least rte_flow_query() is impacted.
Please update doc/guides/prog_guide/rte_flow.rst as well (look for "COUNT
query").

First, since they are added at the end of enum rte_flow_item_type, no ABI
breakage notice is necessary.
However testpmd implementation [1][2] and documentation update [3][4] are
mandatory for all new pattern items and actions.
More comments below regarding these definitions.

[2] using ITEM_ICMP as an example in app/test-pmd/cmdline_flow.c

While you're right to make "IPv4" clear since ARP is also used for other
protocols DPDK doesn't support (and likely never will), the ARP header has
both a fixed and a variably-sized part.
Ideally an ARP pattern item should match the fixed part only and a separate
ARP_IPV4 match its payload, somewhat like you did for ICMPv6/NDP below.
Problem is that in DPDK, struct arp_hdr includes struct arp_ipv4, so one
suggestion would be to rename this pattern item ARP_IPV4 directly:
=> RTE_FLOW_ITEM_TYPE_ARP_IPV4

I'm not sure this definition is necessary, more below about that.
Also I don't see a benefit in having "ANY" part of the name, if you want to
keep it, I suggest the simpler:
=> RTE_FLOW_ITEM_TYPE_IPV6_EXT

Before entering NDP territory below, I understand those should be stacked on
top of RTE_FLOW_ITEM_TYPE_ICMPV6. It's fine but for clarity they should be
named after the NDP types they represent, not inner data fields.
Also I think we should consider NDP as a protocol sitting on top of
ICMPv6. We could therefore drop "ICMP" from these definitions.
Since "ND" is a common shorthand for this protocol and "6" another when
doing something related to IPv6, I suggest to use "ND6" to name he related
pattern items.
These are the reasons behind my next suggestions:

=> Matches an IPv6 network discovery router solicitation.
=> See struct rte_flow_item_nd6_rs.
=> RTE_FLOW_ITEM_TYPE_ND6_RS,
You should add another item for neighbor advertisement messages using the
same template:
=> Match an IPv6 network discovery neighbor advertisement.
=> See struct rte_flow_item_nd6_na.
=> RTE_FLOW_ITEM_TYPE_ND6_NA,
The following are possible options for these headers, if specified they must
be found afterward. Also since IPv6 may run on top of protocols other than
Ethernet, you need to clarify these link-layer addresses use the Ethernet
format:

Needs #include <rte_arp.h> and a Doxygen comment next to hdr for

So what's the point? next_hdr is already part of either struct ipv6_hdr
("proto") and individual extension headers. Moreover it's implicit if an
extension header is provided in a pattern.
How about removing it?

Too bad there is no struct icmp6_hdr definition in rte_icmp.h. You could add
it. In any case Doxygen comments are missing, please add them (see other
structure definitions for examples).

You must remove checksum matching from the default mask. That's the last

You need to expand this as two items, see prior comments regarding
RTE_FLOW_ITEM_TYPE_ND6_RS, RTE_FLOW_ITEM_TYPE_ND6_NA and their respective
structs rte_flow_item_nd6_rs and rte_flow_item_nd6_na.
Also Doxygen documentation is missing for the addr field and you need to
describe that these are only valid when used after
RTE_FLOW_ITEM_TYPE_ICMPV6.

That's a valid concern. I can make it private by merging into the _attach_to()
func, or I just can add a comment in the API doc. However, if users are aware
that a mbuf is read-only and we expect them to keep it intact by their own
judgement, they would/should not use those APIs. We can't stop them modifying
content or the buffer itself anyway. Will add more comments of this discussion
regarding read-only mode.

Can you let me know where I can find the constraint? I checked
rte_pktmbuf_pool_create() and rte_pktmbuf_init() again to not make any mistake
but there's no such limitation.
elt_size = sizeof(struct rte_mbuf) + (unsigned)priv_size +
(unsigned)data_room_size;
The max of data_room_size is 64kB, so is priv_size. m->buf_addr starts from 'm +
sizeof(*m) + priv_size' and m->buf_len can't be larger than UINT16_MAX. So,
priv_size couldn't be used for this purpose.

Hi Adrien:
Thank you so much for your careful review and helpful suggestions!
I agree with most of your comments, except couple question about RTE_FLOW_ITEM_TYPE_TGT_ADDR and RTE_FLOW_ITEM_IPV6_EXT_HDR
Please see my comment inline.
Thanks!

The purpose of RTE_FLOW_ITEM_TYPE_ICMPV6_TGT_ADDR is to match a "target address"
according to IPv6 ND spec https://tools.ietf.org/html/rfc4861#page-22, when type = 135/136
so do you mean we should have RTE_FLOW_ITEM_TYPE_ND6_NS (Neighbor Solicitation)
and RTE_FLOW_ITEM_TYPE_ND6_NA (Neighbor Advertisement) here,
and with the same template (an IPV6 addr) for rte_flow_item_icmpv6_tgt_addr?

We need this to match a packet that have extend header
For example:
IPV6(proto = 43, <Routing EH >) / EXT_HDR (next_head = 60 <Destination EH>) / EXT_HDR (next_head = 44, <Fragment EH)/ EXT_HDR (next_head = 6 <tcp>) / TCP ...
I use "ANY" to match any extend header regardless their content.
There is no conflict if we can add multiple RTE_FLOW_ITEM_EXT_HDR_XXX in futures

+IFCVF vDPA driver
+=================
+
+The IFCVF vDPA (vhost data path acceleration) driver provides support for the
+Intel FPGA 100G VF (IFCVF). IFCVF's datapath is virtio ring compatible, it
+works as a HW vhost backend which can send/receive packets to/from virtio
+directly by DMA. Besides, it supports dirty page logging and device state
+report/restore. This driver enables its vDPA functionality with live migration
+feature.
+
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following option can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_LIBRTE_IFCVF_VDPA_PMD`` (default ``y`` for linux)
+
+ Toggle compilation of the ``librte_ifcvf_vdpa`` driver.
+
+
+IFCVF vDPA Implementation
+-------------------------
+
+IFCVF's vendor ID and device ID are same as that of virtio net pci device,
+with its specific subsystem vendor ID and device ID. To let the device be
+probed by IFCVF driver, adding "vdpa=1" parameter helps to specify that this
+device is to be used in vDPA mode, rather than polling mode, virtio pmd will
+skip when it detects this message.
+
+Different VF devices serve different virtio frontends which are in different
+VMs, so each VF needs to have its own DMA address translation service. During
+the driver probe a new container is created for this device, with this
+container vDPA driver can program DMA remapping table with the VM's memory
+region information.
+
+Key IFCVF vDPA driver ops
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- ifcvf_dev_config:
+ Enable VF data path with virtio information provided by vhost lib, including
+ IOMMU programming to enable VF DMA to VM's memory, VFIO interrupt setup to
+ route HW interrupt to virtio driver, create notify relay thread to translate
+ virtio driver's kick to a MMIO write onto HW, HW queues configuration.
+
+ This function gets called to set up HW data path backend when virtio driver
+ in VM gets ready.
+
+- ifcvf_dev_close:
+ Revoke all the setup in ifcvf_dev_config.
+
+ This function gets called when virtio driver stops device in VM.
+
+To create a vhost port with IFC VF
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Create a vhost socket and assign a VF's device ID to this socket via
+ vhost API. When QEMU vhost connection gets ready, the assigned VF will
+ get configured automatically.
+
+
+Features
+--------
+
+Features of the IFCVF driver are:
+
+- Compatibility with virtio 0.95 and 1.0.
+- Live migration.
+
+
+Prerequisites
+-------------
+
+- Platform with IOMMU feature. IFC VF needs address translation service to
+ Rx/Tx directly with virtio driver in VM.
+
+
+Limitations
+-----------
+
+Dependency on vfio-pci
+~~~~~~~~~~~~~~~~~~~~~~
+
+vDPA driver needs to setup VF MSIX interrupts, each queue's interrupt vector
+is mapped to a callfd associated with a virtio ring. Currently only vfio-pci
+allows multiple interrupts, so the IFCVF driver is dependent on vfio-pci.
+
+Live Migration with VIRTIO_NET_F_GUEST_ANNOUNCE
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+IFC VF doesn't support RARP packet generation, virtio frontend supporting

=========================================================
+* **Added IFCVF vDPA driver.**
+
+ Added IFCVF vDPA driver to support Intel FPGA 100G VF device. IFCVF works
+ as a HW vhost data path accelerator, it supports live migration and is
+ compatible with virtio 0.95 and 1.0. This driver registers ifcvf vDPA driver
+ to vhost lib, when virtio connected, with the help of the registered vDPA

By the way, I wrote "router solicitation" (RS) here but it should have been
"neighbor solicitation" (NS) obviously.

The rationale is that while they share a similar format, they are in fact
different messages that applications could want to match more conveniently
than providing ICMP type/code values. It would be done for consistency given
the same RFC also defines router solicitation/advertisement messages.
However a problem remains since these messages are part of the ICMP format
whose "reserved" field sometimes contains message flags, particularly with
RA. These structures would lack that data.
Honestly your approach makes sense, but it shouldn't be possible to mix
target addresses with RA/RS and it should be convenient to match these
messages without specifically matching their contents.
So another suggestion would be to define new types at the ICMPv6 level to
use directly on top of ETH for each possible message and define separate
structures for options.
First let's drop one character here and in all other definitions in this
patch:
ICMPV6 => ICMP6
Then the new items would respectively be:
RTE_FLOW_ITEM_TYPE_ICMP6
RTE_FLOW_ITEM_TYPE_ICMP6_ND_NA
RTE_FLOW_ITEM_TYPE_ICMP6_ND_NS
RTE_FLOW_ITEM_TYPE_ICMP6_ND_OPT_SLA
RTE_FLOW_ITEM_TYPE_ICMP6_ND_OPT_TLA
All the related structure definitions would include the ICMPv6 header part
defined according to the RFC and except for RTE_FLOW_ITEM_TYPE_ICMP6, a
default mask that excludes type/code since they are implicit:
struct rte_flow_item_icmp6_nd_na {
uint8_t type; /**< ICMPv6 type, normally 136. */
uint8_t code; /**< ICMPv6 code, normally 0. */
rte_be16_t checksum; /**< ICMPv6 checksum. */
/**
* Router flag (1b), solicited flag (1b), override flag (1b),
* reserved (29b).
*/
rte_be32_t rso_reserved;
uint8_t target[16]; /**< Target address. */
};
static const struct rte_flow_item_icmp6_nd_na rte_flow_item_icmp6_nd_na_mask = {
.target =
"\xff\xff\xff\xff\xff\xff\xff\xff"
"\xff\xff\xff\xff\xff\xff\xff\xff",
};
Also notice how uint(16|32)_t were modified as rte_be(16|32)_t while there.
What's your opinion?

I see, makes sense. How about doing like ICMPv6 above? Generic item uses
the base name and can only match the generic part specifically (next_hdr),
while specific items don't match the generic part but whatever additions
their dedicated structures define, i.e.:
RTE_FLOW_ITEM_TYPE_IPV6_EXT
RTE_FLOW_ITEM_TYPE_IPV6_EXT_HBH
RTE_FLOW_ITEM_TYPE_IPV6_EXT_DEST
RTE_FLOW_ITEM_TYPE_IPV6_EXT_RTHDR
RTE_FLOW_ITEM_TYPE_IPV6_EXT_FRAG
...
No need to define them all if you only need EXT, this is just to describe
the idea (it's also OK if you want to define them while you're at it).

For API docs and wording,
Acked-by: Anatoly Burakov <anatoly.burakov@intel.com>
Should be pretty straightforward to rebase, so you probably should keep
my ack for v4.

Ok, so these functions are intended to be used only by PMD level?
But in that case do you need them at all?
Isn't it possible implement same thing with just data_off?
I mean your PMD knows in advance what is the buf_len of mbuf and at startup
time it can decide it going to slice it how to slice it into multiple packets.
So each offset is known in advance and you don't need to worry that you'll overwrite
neighbor packet's data.

Ok I scanned through librte_mbuf and didn't find any limitations.
Seems like a false impression from my side.
Anyway that seems like a corner case to have priv_szie + buf_len >64KB.
Do you really need to support it?

Since Olivier's last comment, I've been thinking about the approach all over
again. It looks like I'm trapped in self-contradiction. The reason why I didn't
want to use data_off was to provide valid headroom for each Rx packet and let
users freely write the headroom. But, given that indirect mbuf should be
considered read-only, this isn't a right approach. Instead of slicing a buffer
with mbuf indirection and manipulating boundaries, the idea of external data (as
Olivier suggested) would fit better. Even though it is more complex, it is
doable. I summarized ideas yesterday and will come up with a new patch soon.
Briefly, I think reserved bit 61 of ol_flags can be used to indicate externally
attached mbuf. The following is my initial thought.
#define EXT_ATTACHED_MBUF (1ULL << 61)
struct rte_pktmbuf_ext_shared_info {
refcnt;
*free_cb();
*opaque /* arg for free_cb() */
}
rte_pktmbuf_get_ext_shinfo() {
/* Put shared info at the end of external buffer */
return (struct rte_pktmbuf_ext_shared_info *)(m->buf_addr + m->buf_len);
}
rte_pktmbuf_attach_ext_buf(m, buf_addr, buf_len, free_cb, opaque) {
struct rte_pktmbuf_ext_shared_info *shinfo;
m->buf_addr = buf_addr;
m->buf_iova = rte_mempool_virt2iova(buf_addr);
/* Have to add some calculation for alignment */
m->buf_len = buf_len - sizeof (*shinfo);
shinfo = m->buf_addr + m->buf_len;
...
m->data_off = RTE_MIN(RTE_PKTMBUF_HEADROOM, (uint16_t)m->buf_len);
m->ol_flags |= EXT_ATTACHED_MBUF;
atomic set shinfo->refcnt = 1;
shinfo->free_cb = free_cb;
shinfo->opaque = opaque;
...
}
rte_pktmbuf_detach_ext_buf(m)
#define RTE_MBUF_EXT(mb) ((mb)->ol_flags & EXT_ATTACHED_MBUF)
In rte_pktmbuf_prefree_seg(),
if (RTE_MBUF_INDIRECT(m))
rte_pktmbuf_detach(m);
else if (RTE_MBUF_EXT(m))
rte_pktmbuf_detach_ext_buf(m);
And in rte_pktmbuf_attach(), if the mbuf attaching to is externally attached,
then just increase refcnt in shinfo so that multiple mbufs can refer to the same
external buffer.
Please feel free to share any concern/idea.

If a user must have 64kB buffer (it's valid, no violation) and the priv_size is
just a few bytes. Then, does library have to force the user to sacrifice a few
bytes for priv_size? Do you think it's a corner case? Still using priv_size
doesn't seem to be a good idea.

Hi Arnon,
When sending new versions, the entire patchset must be sent. It makes it
easier for maintainers to apply patches this way.

librte_bpf provides a framework to load and execute eBPF bytecode
inside user-space dpdk based applications.
It supports basic set of features from eBPF spec
(https://www.kernel.org/doc/Documentation/networking/filter.txt).
Not currently supported features:
- JIT
- cBPF
- tail-pointer call
- eBPF MAP
- skb
- function calls for 32-bit apps
It also adds dependency on libelf.

Cc: dev, arnon
The purpose of this patch series is to cleanup the library code
from paths that end up aborting the process,
and move to checking error values, in order to allow the running process
perform an orderly teardown or other mitigation of the event.
This patch modifies the majority of rte_panic calls
under lib and drivers, and replaces them with a log message
and an error return code according to context,
that can be propagated up the call stack.
- Focus was given to the dpdk initialization path
- Some of the panic calls within drivers were left in place where
the call is from within an interrupt or calls that are
on the data path,where there is no simple applicative
route to propagate the error to temination.
These should be handled by the driver maintainers.
- In order to avoid breaking ABI where panic was called from public
void functions, a panic state variable was introduced so that
it can be queried after calling these void functions.
This tool place for a single function call.
- local void functions with no api were changed to retrun a value
where needed
- No change took place in example and test files
- No change took place for debug assertions calling panic
- A new function was added to devtools/checkpatches.sh
in order to prevent new additions of calls to rte_panic
under lib and drivers.
Keep calm and don't panic
---
v2:
- reformat error messages so that literal string are in the same line
- fix typo in commit message
- add new return code to doxigen of rte_memzone_free()
v3:
- submit all 13 patches changed and unchanged in the same patchset

Local functions to this file,
changing from void to int are non-abi-breaking.
For handling the single function that cannot
change from void to int due to abi,
where this is the only place it is called in,
I added a state variable that is being checked
right after the call to this function.

This patch implements the initialization of the virtio crypto device.
The virtio crypto device conforms to virtio-1.0, so this patch only
supports modern mode operation.
The cryptodev is created at the virtio crypto pci device probing stage.
The function of virtio_crypto_pkt_tx_burst() is used to burst transfer
packets and virtio_crypto_pkt_rx_burst() is used to burst receive packets.

jianjay.zhou
This patch implements the initialization of the virtio crypto device.
The virtio crypto device conforms to virtio-1.0, so this patch only
supports modern mode operation.
The cryptodev is created at the virtio crypto pci device probing stage.
The function of virtio_crypto_pkt_tx_burst() is used to burst transfer
packets and virtio_crypto_pkt_rx_burst() is used to burst receive packets.

This patch implements the initialization of the virtio crypto device.
The virtio crypto device conforms to virtio-1.0, so this patch only
supports modern mode operation.
The cryptodev is created at the virtio crypto pci device probing stage.
The function of virtio_crypto_pkt_tx_burst() is used to burst transfer
packets and virtio_crypto_pkt_rx_burst() is used to burst receive packets.

This patchset needs to be rebased. There were a few changes that make
some of the patches unnecessary.
Changes in patch 7 and 9 were addressed in earlier memory hotplug
patchset, and are no longer applicable. Some things may have changed for
patch 12 as well.

Size of memory chunk required to populate mempool objects depends
on how objects are stored in the memory. Different mempool drivers
may have different requirements and a new operation allows to
calculate memory size in accordance with driver requirements and
advertise requirements on minimum memory chunk size and alignment
in a generic way.
Bump ABI version since the patch breaks it.
Suggested-by: Olivier Matz <olivier.matz@6wind.com>
Signed-off-by: Andrew Rybchenko <arybchenko@solarflare.com>

v3 -> v4:
- rebased on top of memory rework
- dropped previous Ack's since rebase is not trivial
- check size calculation failure in rte_mempool_populate_anon() and
rte_mempool_memchunk_anon_free()
v2 -> v3:
- none
v1 -> v2:
- clarify min_chunk_size meaning
- rebase on top of patch series which fixes library version in meson
build
RFCv2 -> v1:
- move default calc_mem_size callback to rte_mempool_ops_default.c
- add ABI changes to release notes
- name default callback consistently: rte_mempool_op_<callback>_default()
- bump ABI version since it is the first patch which breaks ABI
- describe default callback behaviour in details
- avoid introduction of internal function to cope with deprecation
(keep it to deprecation patch)
- move cache-line or page boundary chunk alignment to default callback
- highlight that min_chunk_size and align parameters are output only

The callback allows to customize how objects are stored in the
memory chunk. Default implementation of the callback which simply
puts objects one by one is available.

to populate objects using provided memory area which provides
the same information.

The callback was introduced to let generic code to know octeontx
mempool driver requirements to use single physically contiguous
memory chunk to store all objects and align object address to
total object size. Now these requirements are met using a new
callbacks to calculate required memory chunk size and to populate
objects using provided memory chunk.
These capability flags are not used anywhere else.
Restricting capabilities to flags is not generic and likely to
be insufficient to describe mempool driver features. If required
in the future, API which returns structured information may be
added.

The initial patch series [1] is split into two to simplify processing.
The second series relies on this one and will add bucket mempool driver
and related ops.
The patch series has generic enhancements suggested by Olivier.
Basically it adds driver callbacks to calculate required memory size and
to populate objects using provided memory area. It allows to remove
so-called capability flags used before to tell generic code how to
allocate and slice allocated memory into mempool objects.
Clean up which removes get_capabilities and register_memory_area is
not strictly required, but I think right thing to do.
Existing mempool drivers are updated.
rte_mempool_populate_iova_tab() is also deprecated in v2 as agreed in [2].
Unfortunately it requires addition of -Wno-deprecated-declarations flag
to librte_mempool since the function is used by deprecated earlier
rte_mempool_populate_phys_tab(). If the later may be removed in the
release, we can avoid addition of the flag to allow usage of deprecated
functions.
A new patch is added to the series in v3 to rename MEMPOOL_F_NO_PHYS_CONTIG
as MEMPOOL_F_NO_IOVA_CONTIG as agreed in [3].
MEMPOOL_F_CAPA_PHYS_CONTIG is not renamed since it removed in this
patchset.
It breaks ABI since changes rte_mempool_ops. Also it removes
rte_mempool_ops_register_memory_area() and
rte_mempool_ops_get_capabilities() since corresponding callbacks are
removed.
Internal global functions are not listed in map file since it is not
a part of external API.

v3 -> v4:
- rebase on memory rework
v2 -> v3:
- fix build error in mempool/dpaa: prepare to remove register memory area op
v1 -> v2:
- deprecate rte_mempool_populate_iova_tab()
- add patch to fix memory leak if no objects are populated
- add patch to rename MEMPOOL_F_NO_PHYS_CONTIG
- minor fixes (typos, blank line at the end of file)
- highlight meaning of min_chunk_size (when it is virtual or
physical contiguous)
- make sure that mempool is initialized in rte_mempool_populate_anon()
- move patch to ensure that mempool is initialized earlier in the series
RFCv2 -> v1:
- split the series in two
- squash octeontx patches which implement calc_mem_size and populate
callbacks into the patch which removes get_capabilities since it is
the easiest way to untangle the tangle of tightly related library
functions and flags advertised by the driver
- consistently name default callbacks
- move default callbacks to dedicated file
- see detailed description in patches
RFCv1 -> RFCv2:
- add driver ops to calculate required memory size and populate
mempool objects, remove extra flags which were required before
to control it
- transition of octeontx and dpaa drivers to the new callbacks
- change info API to get information from driver required to
API user to know contiguous block size
- remove get_capabilities (not required any more and may be
substituted with more in info get API)
- remove register_memory_area since it is substituted with
populate callback which can do more
- use SPDX tags
- avoid all objects affinity to single lcore
- fix bucket get_count
- deprecate XMEM API
- avoid introduction of a new function to flush cache
- fix NO_CACHE_ALIGN case in bucket mempool
Andrew Rybchenko (9):
mempool: fix memhdr leak when no objects are populated
mempool: rename flag to control IOVA-contiguous objects
mempool: add op to calculate memory size to be allocated
mempool: add op to populate objects using provided memory
mempool: remove callback to get capabilities
mempool: deprecate xmem functions
mempool/octeontx: prepare to remove register memory area op
mempool/dpaa: prepare to remove register memory area op
mempool: remove callback to register memory area
Artem V. Andreev (2):
mempool: ensure the mempool is initialized before populating
mempool: support flushing the default cache of the mempool

and non-deprecated rte_mempool_op_calc_mem_size_default().

v2 -> v3:
- none
v1 -> v2:
- deprecate rte_mempool_populate_iova_tab()
- add -Wno-deprecated-declarations to fix build errors because of
rte_mempool_populate_iova_tab() deprecation
- add @deprecated to deprecated functions description
RFCv2 -> v1:
- advertise deprecation in release notes
- factor out default memory size calculation into non-deprecated
internal function to avoid usage of deprecated function internally
- remove test for deprecated functions to address build issue because
of usage of deprecated functions (it is easy to allow usage of
deprecated function in Makefile, but very complicated in meson)

To: dev; +Cc: Olivier MATZ
The initial patch series [1] (RFCv1 is [2]) is split into two to simplify
processing. It is the second part which relies on the first one [3].
It should be applied on top of [3].
The patch series adds bucket mempool driver which allows to allocate
(both physically and virtually) contiguous blocks of objects and adds
mempool API to do it. It is still capable to provide separate objects,
but it is definitely more heavy-weight than ring/stack drivers.
The driver will be used by the future Solarflare driver enhancements
which allow to utilize physical contiguous blocks in the NIC firmware.
The target usecase is dequeue in blocks and enqueue separate objects
back (which are collected in buckets to be dequeued). So, the memory
pool with bucket driver is created by an application and provided to
networking PMD receive queue. The choice of bucket driver is done using
rte_eth_dev_pool_ops_supported(). A PMD that relies upon contiguous
block allocation should report the bucket driver as the only supported
and preferred one.
Introduction of the contiguous block dequeue operation is proven by
performance measurements using autotest with minor enhancements:
- in the original test bulks are powers of two, which is unacceptable
for us, so they are changed to multiple of contig_block_size;
- the test code is duplicated to support plain dequeue and
dequeue_contig_blocks;
- all the extra test variations (with/without cache etc) are eliminated;
- a fake read from the dequeued buffer is added (in both cases) to
simulate mbufs access.

The number of objects in the contiguous block is a function of bucket
memory size (.config option) and total element size. In the future
additional API with possibility to pass parameters on mempool allocation
may be added.
It breaks ABI since changes rte_mempool_ops. The ABI version is already
bumped in [4].

v1 -> v2:
- just rebase
RFCv2 -> v1:
- rebased on top of [3]
- cleanup deprecation notice when it is done
- mark a new API experimental
- move contig blocks dequeue debug checks/processing to the library function
- add contig blocks get stats
- add release notes
RFCv1 -> RFCv2:
- change info API to get information from driver required to
API user to know contiguous block size
- use SPDX tags
- avoid all objects affinity to single lcore
- fix bucket get_count
- fix NO_CACHE_ALIGN case in bucket mempool

If mempool manager supports object blocks (physically and virtual
contiguous set of objects), it is sufficient to get the first
object only and the function allows to avoid filling in of
information about each block member.

In case there is a v5 for another reason, I think the last line is
equivalent to:
try_contig = !no_pageshift && rte_eal_has_hugepages();

As summarized in a prior RFC [1], the flow API (rte_flow) was chosen as a
means to manage switch offloads supported by many devices (usually going by
names such as E-Switch or vSwitch) through user-specified flow rules.
Combined with the need to support encap/decap actions, this requires a
change in the way flow actions are processed (in order and possibly
repeated) which modifies the behavior of some of the existing actions, thus
warranting a major ABI breakage.
Given this ABI breakage is also required by other work submitted for the
current release [2][3], this series addresses various longstanding issues
with the flow API and makes minor improvements in preparation for upcoming
features.
Changes summary:
- Additional error types.
- Clearer documentation.
- Improved C++ compatibility.
- Exhaustive RSS action.
- Consistent behavior of VLAN pattern item.
- New "transfer" attribute bringing consistency to VF/PF pattern items.
- Confusing "PORT" pattern item renamed "PHY_PORT", with new action
counterpart.
- New "PORT_ID" pattern item and action to be used with port representors.
This series piggybacks on the major ABI update introduced by a prior
commit [4] for DPDK 18.05 and depends on several fixes [5] which must be
applied first.
[1] "[RFC] Switch device offload with DPDK"
http://dpdk.org/ml/archives/dev/2018-March/092513.html
[2] commit 676b605182a5 ("doc: announce ethdev API change for RSS
configuration")
[3] "[PATCH v1 00/21] MLX5 tunnel Rx offloading"
http://dpdk.org/ml/archives/dev/2018-March/092264.html
[4] commit 653e038efc9b ("ethdev: remove versioning of filter control
function")
[5] "[PATCH v4 00/11] Bunch of flow API-related fixes"
http://dpdk.org/ml/archives/dev/2018-April/096509.html
v5 changes:
- No change besides new acked-by lines, rebased series to address conflicts.
v3 changes:
- Rebased series, fixed latest conflicts.
- Addressed Andrew's comments, see affected patches for details:
- Empty RSS types in flow rule means PMD-specific RSS instead of no RSS.
- RSS hash function now explicitly compared against
RTE_ETH_HASH_FUNCTION_DEFAULT instead of 0 in all PMDs.
- sfc PMD updated to also accept Toeplitz.
- Implicit VLAN TPID matching now removed from all PMDs.
- Default mask upate for VLAN TCI now split as separate patch #11.
- Ingress/egress definition clarified in patch #12.
v2 changes:
- Squashed "ethdev: update ABI for flow API functions" in subsequent
patches.
- Emphasized ABI impact in relevant commit logs.
- Modified documentation in "ethdev: alter behavior of flow API actions" to
describe how terminating flow rules without any action of the fate kind
result in undefined behavior instead of dropping traffic.
- Fixed other minor documentation formatting issues.
- Modified "ethdev: refine TPID handling in flow API" as follows:
- Using standard macro definitions for VLAN, QinQ and E-Tag EtherTypes.
- Fixed endian conversion in sfc.
- Replaced a condition in VLAN pattern item processing with an assertion
check for i40e.

These enable more precise reporting of objects responsible for errors.
This breaks ABI compatibility for the following public functions:
- rte_flow_create()
- rte_flow_destroy()
- rte_flow_error_set()
- rte_flow_flush()
- rte_flow_isolate()
- rte_flow_query()
- rte_flow_validate()

Upcoming changes in relation to the handling of actions list will make the
DUP action redundant as specifying several QUEUE actions will achieve the
same behavior. Besides, no PMD implements this action.
By removing an entry from enum rte_flow_action_type, this patch breaks ABI
compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

This patch makes the following changes to flow rule actions:
- List order now matters, they are redefined as performed first to last
instead of "all simultaneously".
- Repeated actions are now supported (e.g. specifying QUEUE multiple times
now duplicates traffic among them). Previously only the last action of
any given kind was taken into account.
- No more distinction between terminating/non-terminating/meta actions.
Flow rules themselves are now defined as always terminating unless a
PASSTHRU action is specified.
These changes alter the behavior of flow rules in corner cases in order to
prepare the flow API for actions that modify traffic contents or properties
(e.g. encapsulation, compression) and for which order matter when combined.
Previously one would have to do so through multiple flow rules by combining
PASSTRHU with priority levels, however this proved overly complex to
implement at the PMD level, hence this simpler approach.
This breaks ABI compatibility for the following public functions:
- rte_flow_create()
- rte_flow_validate()
PMDs with rte_flow support are modified accordingly:
- bnxt: no change, implementation already forbids multiple actions and does
not support PASSTHRU.
- e1000: no change, same as bnxt.
- enic: modified to forbid redundant actions, no support for default drop.
- failsafe: no change needed.
- i40e: no change, implementation already forbids multiple actions.
- ixgbe: same as i40e.
- mlx4: modified to forbid multiple fate-deciding actions and drop when
unspecified.
- mlx5: same as mlx4, with other redundant actions also forbidden.
- sfc: same as mlx4.
- tap: implementation already complies with the new behavior except for
the default pass-through modified as a default drop.

From: Adrien Mazarguil @ 2018-04-16 16:22 UTC (permalink / raw)
To: Thomas Monjalon, Ferruh Yigit, dev
This patch replaces C99-style flexible arrays in struct rte_flow_action_rss
and struct rte_flow_item_raw with standard pointers to the same data.
They proved difficult to use in the field (e.g. no possibility of static
initialization) and unsuitable for C++ applications.
Affected PMDs and examples are updated accordingly.
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

Since its inception, the rte_flow RSS action has been relying in part on
external struct rte_eth_rss_conf for compatibility with the legacy RSS API.
This structure lacks parameters such as the hash algorithm to use, and more
recently, a method to tell which layer RSS should be performed on [1].
Given struct rte_eth_rss_conf will never be flexible enough to represent a
complete RSS configuration (e.g. RETA table), this patch supersedes it by
extending the rte_flow RSS action directly.
A subsequent patch will add a field to use a non-default RSS hash
algorithm. To that end, a field named "types" replaces the field formerly
known as "rss_hf" and standing for "RSS hash functions" as it was
confusing. Actual RSS hash function types are defined by enum
rte_eth_hash_function.
This patch updates all PMDs and example applications accordingly.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

v3 changes:
Documentation update regarding the meaning of a 0 value for RSS types in
flow rules.
It used to implicitly mean "no RSS" but is redefined as requesting a kind
of "best-effort" mode from PMDs, i.e. anything ranging from empty to
all-inclusive RSS; what matters is it provides safe defaults that will work
regardless of PMD capabilities.

By definition, RSS involves some kind of hash algorithm, usually Toeplitz.
Until now it could not be modified on a flow rule basis and PMDs had to
always assume RTE_ETH_HASH_FUNCTION_DEFAULT, which remains the default
behavior when unspecified (0).
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

v3 changes:
- Although RTE_ETH_HASH_FUNCTION_DEFAULT is defined as 0, made comparisons
more explicit where doing so would clarify the code.
- Updated sfc to include Toeplitz as the other allowed value.
Both according to Andrew's suggestions [1].

RSS hash types (ETH_RSS_* macros defined in rte_ethdev.h) describe the
protocol header fields of a packet that must be taken into account while
computing RSS.
When facing encapsulated (e.g. tunneled) packets, there is an ambiguity as
to whether these should apply to inner or outer packets. Applications need
the ability to tell exactly "where" RSS must be performed.
This is addressed by adding encapsulation level information to the RSS flow
action. Its default value is 0 and stands for the usual unspecified
behavior. Other values provide a specific encapsulation level.
Contrary to the change announced by commit 676b605182a5 ("doc: announce
ethdev API change for RSS configuration"), this patch does not affect
struct rte_eth_rss_conf but struct rte_flow_action_rss as the former is not
used anymore by the RSS flow action. ABI impact is therefore limited to
rte_flow.
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

TPID handling in rte_flow VLAN and E_TAG pattern item definitions is not
consistent with the normal stacking order of pattern items, which is
confusing to applications.
Problem is that when followed by one of these layers, the EtherType field
of the preceding layer keeps its "inner" definition, and the "outer" TPID
is provided by the subsequent layer, the reverse of how a packet looks like
on the wire:
Wire: [ ETH TPID = A | VLAN EtherType = B | B DATA ]
rte_flow: [ ETH EtherType = B | VLAN TPID = A | B DATA ]
Worse, when QinQ is involved, the stacking order of VLAN layers is
unspecified. It is unclear whether it should be reversed (innermost to
outermost) as well given TPID applies to the previous layer:
Wire: [ ETH TPID = A | VLAN TPID = B | VLAN EtherType = C | C DATA ]
rte_flow 1: [ ETH EtherType = C | VLAN TPID = B | VLAN TPID = A | C DATA ]
rte_flow 2: [ ETH EtherType = C | VLAN TPID = A | VLAN TPID = B | C DATA ]
While specifying EtherType/TPID is hopefully rarely necessary, the stacking
order in case of QinQ and the lack of documentation remain an issue.
This patch replaces TPID in the VLAN pattern item with an inner
EtherType/TPID as is usually done everywhere else (e.g. struct vlan_hdr),
clarifies documentation and updates all relevant code.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()
Summary of changes for PMDs that implement ETH, VLAN or E_TAG pattern
items:
- bnxt: EtherType matching is supported with and without VLAN, but TPID
matching is not and triggers an error.
- e1000: EtherType matching is only supported with the ETHERTYPE filter,
which does not support VLAN matching, therefore no impact.
- enic: same as bnxt.
- i40e: same as bnxt with existing FDIR limitations on allowed EtherType
values. The remaining filter types (VXLAN, NVGRE, QINQ) do not support
EtherType matching.
- ixgbe: same as e1000, with additional minor change to rely on the new
E-Tag macro definition.
- mlx4: EtherType/TPID matching is not supported, no impact.
- mlx5: same as bnxt.
- mvpp2: same as bnxt.
- sfc: same as bnxt.
- tap: same as bnxt.

v3 changes:
Updated mrvl to mvpp2.
Moved unrelated default TCI mask update to separate patch.
Fixed sfc according to Andrew's comments [1], which made so much sense that
I standardized on the same behavior for all other PMDs: matching outer TPID
is never supported when a VLAN pattern item is present.
This is done because many devices accept several TPIDs but do not provide
means to match a given one explicitly, it's all or nothing, and that makes
the resulting flow rule inaccurate.

To: Thomas Monjalon, Ferruh Yigit, dev; +Cc: Andrew Rybchenko
This new attribute enables applications to create flow rules that do not
simply match traffic whose origin is specified in the pattern (e.g. some
non-default physical port or VF), but actively affect it by applying the
flow rule at the lowest possible level in the underlying device.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_validate()
Signed-off-by: Adrien Mazarguil <adrien.mazarguil@6wind.com>
Cc: Andrew Rybchenko <arybchenko@solarflare.com>

v3 changes:
Clarified definition for ingress and egress following Andrew's comment on
subsequent patch.

Specifying both directions at once for a given rule is not recommended but
may be valid in a few cases (e.g. shared counters).
+Attribute: Transfer
+^^^^^^^^^^^^^^^^^^^
+
+Instead of simply matching the properties of traffic as it would appear on a
+given DPDK port ID, enabling this attribute transfers a flow rule to the
+lowest possible level of any device endpoints found in the pattern.
+
+When supported, this effectively enables an application to reroute traffic
+not necessarily intended for it (e.g. coming from or addressed to different
+physical ports, VFs or applications) at the device level.
+
+It complements the behavior of some pattern items such as `Item: PORT`_ and
+is meaningless without them.
+
+When transferring flow rules, **ingress** and **egress** attributes
+(`Attribute: Traffic direction`_) keep their original meaning, as if
+processing traffic emitted or received by the application.

Contrary to all other pattern items, these are inconsistently documented as
affecting traffic instead of simply matching its origin, without provision
for the latter.
This commit clarifies documentation and updates PMDs since the original
behavior now has to be explicitly requested using the new transfer
attribute.
It breaks ABI compatibility for the following public functions:
- rte_flow_create()
- rte_flow_validate()
Impacted PMDs are bnxt and i40e, for which the VF pattern item is now only
supported when a transfer attribute is also present.

While RTE_FLOW_ITEM_TYPE_PORT refers to physical ports of the underlying
device using specific identifiers, these are often confused with DPDK port
IDs exposed to applications in the global name space.
Since this pattern item is seldom used, rename it RTE_FLOW_ITEM_PHY_PORT
for better clarity.
No ABI impact.

This patch adds the missing action counterpart to the PHY_PORT pattern
item, that is, the ability to directly inject matching traffic into a
physical port of the underlying device.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

RTE_FLOW_ACTION_TYPE_PORT_ID brings the ability to inject matching traffic
into a different device, as identified by its DPDK port ID.
This is normally only supported when the target port ID has some kind of
relationship with the port ID the flow rule is created against, such as
being exposed by a common physical device (e.g. a different port of an
Ethernet switch).
The converse pattern item, RTE_FLOW_ITEM_TYPE_PORT_ID, makes the resulting
flow rule match traffic whose origin is the specified port ID. Note that
specifying a port ID that differs from the one the flow rule is created
against is normally meaningless (if even accepted), but can make sense if
combined with the transfer attribute.
These must not be confused with their PHY_PORT counterparts, which refer to
physical ports using device-specific indices, but unlike PORT_ID are not
necessarily tied to DPDK port IDs.
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

This patch provides the same functionality and supersedes Qi Zhang's
"ether: add flow action to redirect packet to a port" [1].
The main differences are:
- Action is named PORT_ID instead of PORT.
- Addition of a PORT_ID pattern item.
- More extensive documentation.
- Testpmd support.
- rte_flow_copy() support.

* [dpdk-dev] [PATCH v11 02/10] crypto/virtio: support virtio device init
@ 2018-04-17 9:23 1% ` Jay Zhou
0 siblings, 0 replies; 200+ results
From: Jay Zhou @ 2018-04-17 9:23 UTC (permalink / raw)
To: dev
Cc: pablo.de.lara.guarch, roy.fan.zhang, thomas, arei.gonglei,
xin.zeng, weidong.huang, wangxinxin.wang, longpeng2,
jianjay.zhou
This patch implements the initialization of the virtio crypto device.
The virtio crypto device conforms to virtio-1.0, so this patch only
supports modern mode operation.
The cryptodev is created at the virtio crypto pci device probing stage.
The function of virtio_crypto_pkt_tx_burst() is used to burst transfer

This is a bit pessimistic. There may not have been enough
IOVA-contiguous memory to reserve `mem_size`, but there may be enough
contiguous memory to try and reserve `min_chunk_size` contiguous memory
if it's bigger than minimum page size. This is *minimum* page size, so
there may be bigger pages, and ideally if (min_chunk_size >= pg_sz) &&
(min_chunk_size < mem_size), we might've tried to allocate some
IOVA-contiguous memory, and succeed.
However, that's not a huge issue, so...

Sure that makes sense to me, as in a device with multiple groups I would
image that you are more likely to have a tree hierarchy of groups, based
on something like packet types, rather than a straight priority ordering.

I think this is a good idea, as in the case with multiple groups which
support the same packet time, there may be some flows which could
potentially hit on many groups, but should be directed to a specific
group. If group matching was always resolved in a strict priority it
would result on a hit on an incorrect group. I think making it explicit
from the start makes sense.
One issue is that groups will need to be populated with a specific rule
to allow flow to fall through to the next priority group if no match is
found on the default group.
This just requires changes to the API comments, correct? Do you want to
capture those in [1] or would you like me to make them with this patch?

I understand where your coming from here now, I think the best approach
to take is as you say to have the explicit
RTE_FLOW_ACTION_TYPE_(PROTOCOL)_(ENCAP|DECAP) actions and make it
explicit in the action description that it operates within the
constraints of the corresponding RFC. I'll cover VXLAN and NVGRE as
that's what we have been testing with today, as you point it will be
easy to add new protocol encap/decaps without breaking ABI. Also I think
having a explicit decap action for each protocol makes the overall usage
model simpler as it negates the need for action data.

I think that a note to make it explicit that the last item is

For the encap case I still prefer a single definition as an array of
flow items. I think it will make it easier to verify a valid pattern has
all the required elements in terms of the protocol encapsulation being
specified. I see how it could work the other way too, but the validity
of the pattern definition comes from the action, not from any specific
item in the pattern. I think that the error reporting is verbose enough
to allow PMDs to specify exactly why a pattern is invalid for an action.
For instance if you missed the UDP item in a VXLAN encap action
definition, in the single item per encap model you would get the error
on the IP item, but it may actually be perfectly valid, the error is
that you missed the UDP item.

Disclaimer: this patch must not be confused with the CLI library [1]
(work in progress) that will eventually supersede librte_cmdline itself
with a different API.
Rather, it modifies librte_cmdline to delegate all the heavy lifting
(terminal and history handling), strips unused features and re-implements
what remains of its public API as a wrapper to the editline library (also
known as libedit) [2], a well-known, BSD-licensed and widely available
library used by many projects which does everything needed and more [3].
This approach was chosen because converting librte_cmdline as a wrapper to
a more capable library was easier and faster than addressing its
shortcomings and results in much less code to maintain in DPDK.
It also provides a drop-in solution for applications that rely on
librte_cmdline. They benefit from greatly improved command line handling
without a meaningful impact on their code base.
The main motivation behind this patch is testpmd's flow (rte_flow) command,
which requires support for dynamic tokens and very long lines that must be
broken down when displayed. This is not supported by librte_cmdline's
limited terminal handling capabilities, resulting in a rather frustrating
user experience.
It had to be addressed given the importance of testpmd as one of the
primary tool used by PMD developers.
This rework results in the following changes:
- Removed circular buffer management interface for command history
(cmdline_cirbuf.c), command history being handled by libedit.
- Removed raw command-line interpreter (cmdline_rdline.c).
- Removed raw terminal handler (cmdline_vt100.c).
- Removed all test/example code for the above.
- Re-implemented high level interactive and non-interactive command-line
handlers (cmdline.c and cmdline_socket.c) on top of libedit using its
native interface, not its readline compatibility layer.
- Made struct cmdline opaque so that applications relying on librte_cmdline
do not need to include any libedit headers.
- Applications do not need to include cmdline_rdline.h anymore.
- Terminal resizing is now automatically handled.
- New external dependency for applications relying on librte_cmdline.
- Major version bump due to the ABI impact of these changes.

No fundamental change since the original RFC [4], except it's been rebased
several times and Meson build support was added in the meantime. Commit log
was also shortened a bit.
I'm re-sending this because I think it's useful, at least to me (duh). As
the maintainer of rte_flow, I spend most of my time typing flow commands in
testpmd and libedit makes that a pleasant experience.
Try it out! And don't hesitate to send your acked-by line to get this in
time for 18.05 :)

- * This file is a small equivalent to the GNU readline library, but it

- * microcontrollers (8 bits). Indeed, we don't use any malloc that is
- * sometimes not implemented (or just not recommended) on such
- * systems.
- *
- * Obviously, it does not support as many things as the GNU readline,
- * but at least it supports some interesting features like a kill
- * buffer and a command history.
- *
- * It also have a feature that does not have the GNU readline (as far
- * as I know): we can have several instances of it running at the same
- * time, even on a monothread program, since it works with callbacks.
- *
- * The lib is designed for a client-side or a server-side use:
- * - server-side: the server receives all data from a socket, including
- * control chars, like arrows, tabulations, ... The client is
- * very simple, it can be a telnet or a minicom through a serial line.
- * - client-side: the client receives its data through its stdin for
- * instance.

v5:
- Fixed VXLAN-GPE comment alignment
v4:
- Update testpmd doc for flow VXLAN-GPE paramter.
v3:
- Change VXLAN-GPE definition order to avoid ABI compatibility issue.
v2:
- Split patch set into public and mlx5 two series, this one is the first.
v1:
- Support new tunnel type MPLS-in-GRE and MPLS-in-UDP
- Remove deprecation notes of rss level
This patchset introduced new tunnel type and related testpmd code:
- New tunnel type VXLAN-GPE
https://datatracker.ietf.org/doc/draft-ietf-nvo3-vxlan-gpe/
- New tunnel type MPLS-in-GRE
https://tools.ietf.org/html/rfc4023
- New tunnel type MPLS-in-UDP
https://tools.ietf.org/html/rfc7510
- Support GRE extension in testpmd csum forwarding engine

There are almost as much insertions as deletions.
So it's probably not a bad move.

Pure 32bit in our case. We do not use x32 ABI.

A notice covering the main changes in this series (most patches have an ABI
impact) was sent but not included [1]. This particular patch rides on the
announced ABI breakage in order to add a relatively minor feature while
there.
This ABI change was implicitly needed by upcoming work for 18.05 (Xueming's
RSS stuff [2][3], Declan's TEP [4], the rest is summarized by a RFC [5]) due
to the necessary changes of behavior in flow rules.
Note that Xueming's deprecation notice [3] alone would have triggered such
an ABI change because struct rte_flow_action_rss wouldn't have been binary
compatible if struct rte_eth_rss_conf was updated. This change would have
propagated back to rte_flow functions manipulating them.

My take from "announced ABI breakage" is the deprecation notice get three acks
and merged into release, so it seems there is no deprecation notice and
according process first deprecation notice should go in this release.
Hi Thomas,
Any comment on issue?

To be honest I lost track of Xueming's patches, because of split/merge of
patchset, multiple set with multiple versions out.
Is it possible to document the dependency graph including your set?

I have just cloned the current dpdk master, patch 3 still fails to apply, dpdk-dev-v5-3-4-app-testpmd-introduce-new-tunnel-VXLAN-GPE.patch
git am ./dpdk-dev-v5-3-4-app-testpmd-introduce-new-tunnel-VXLAN-GPE.patch
Applying: app/testpmd: introduce new tunnel VXLAN-GPE
error: patch failed: app/test-pmd/config.c:997
error: app/test-pmd/config.c: patch does not apply
Patch failed at 0001 app/testpmd: introduce new tunnel VXLAN-GPE
The copy of the patch that failed is found in:
/root/dpdk_temp/.git/rebase-apply/patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort

Cc: dev, arnon
The purpose of this patch series is to cleanup the library code
from paths that end up aborting the process,
and move to checking error values, in order to allow the running process
perform an orderly teardown or other mitigation of the event.
This patch modifies the majority of rte_panic calls
under lib and drivers, and replaces them with a log message
and an error return code according to context,
that can be propagated up the call stack.
- Focus was given to the dpdk initialization path
- Some of the panic calls within drivers were left in place where
the call is from within an interrupt or calls that are
on the data path,where there is no simple applicative
route to propagate the error to temination.
These should be handled by the driver maintainers.
- In order to avoid breaking ABI where panic was called from public
void functions, a panic state variable was introduced so that
it can be queried after calling these void functions.
This tool place for a single function call.
- local void functions with no api were changed to retrun a value
where needed
- No change took place in example and test files
- No change took place for debug assertions calling panic
- A new function was added to devtools/checkpatches.sh
in order to prevent new additions of calls to rte_panic
under lib and drivers.
Keep calm and don't panic
---
v2:
- reformat error messages so that literal string are in the same line
- fix typo in commit message
- add new return code to doxigen of rte_memzone_free()
v3:
- submit all 13 patches changed and unchanged in the same patchset
v4:
- remove 2 patches that are no more relevant
- fix split literal string in error message
- change return value -1 to enum
- split value and success code in a static function
Arnon Warshavsky (11):
crypto: replace rte_panic instances in crypto driver
bond: replace rte_panic instances in bonding driver
e1000: replace rte_panic instances in e1000 driver
ixgbe: replace rte_panic instances in ixgbe driver

Local functions to this file,
changing from void to int are non-abi-breaking.
For handling the single function that cannot
change from void to int due to abi,
where this is the only place it is called in,
I added a state variable that is being checked
right after the call to this function.

True, so just describe how ABI impact is no worse than what was announced
(and included) [3] and most of them are actually opportune changes to
improve consistency and documentation since ABI would be broken for this
release regardless. Regarding individual patches:
- 01/16 "ethdev: add error types to flow API"
=> New error types are added in the middle of an existing enum.
- 02/16 "ethdev: clarify flow API pattern items and actions"
=> No impact.
- 03/16 "doc: remove flow API migration section"
=> No impact.
- 04/16 "ethdev: remove DUP action from flow API"
=> An action that no PMD supports is removed from an existing enum.
- 05/16 "ethdev: alter behavior of flow API actions"
=> A documentation change in how actions are processed logically
breaks ABI in the case of repeated actions (currently a corner
case). Most PMDs do not implement the original behavior correctly
anyway (see commit log).
- 06/16 "ethdev: remove C99 flexible arrays from flow API"
=> ABI impact is primarily triggered by the RSS action change (already
covered [3]). The RAW pattern item is also modified for consistency.
On the API side, except when allocating these structures, there is no
difference in usage (i.e. array[index] => pointer[index]).
- 07/16 "ethdev: flatten RSS configuration in flow API"
=> Already covered [3].
- 08/16 "ethdev: add hash function to RSS flow API action"
=> Already covered [3].
- 09/16 "ethdev: add encap level to RSS flow API action"
=> Already covered [3].
- 10/16 "ethdev: refine TPID handling in flow API"
=> No PMD supports the poorly defined TPID matching, applications couldn't
possibly rely on it.
- 11/16 "ethdev: limit default VLAN TCI mask in flow API"
=> No ABI breakage, but a different behavior for applications that rely on
the default mask. It doesn't look like any PMD supports PCP/DEI
matching so again applications could not rely on it (they still can do
it by providing a specific mask).
- 12/16 "ethdev: add transfer attribute to flow API"
=> Minor ABI impact (read: logical) due to the addition of a bit in an
existing bit-field. No practical impact on applications.
- 13/16 "ethdev: update behavior of VF/PF in flow API"
=> Documentation (API) change. The "transfer" bit must now be set in order to
use these actions with PMDs that support them.
- 14/16 "ethdev: rename physical port item in flow API"
=> API change for a pattern item supported by no PMD.
- 15/16 "ethdev: add physical port action to flow API"
=> New action added in the middle of an existing enum.
- 16/16 "ethdev: add port ID item and action to flow API"
=> New item/action added in the middle of existing enums.

As summarized in a prior RFC [1], the flow API (rte_flow) was chosen as a
means to manage switch offloads supported by many devices (usually going by
names such as E-Switch or vSwitch) through user-specified flow rules.
Combined with the need to support encap/decap actions, this requires a
change in the way flow actions are processed (in order and possibly
repeated) which modifies the behavior of some of the existing actions, thus
warranting a major ABI breakage.
Given this ABI breakage is also required by other work submitted for the
current release [2][3], this series addresses various longstanding issues
with the flow API and makes minor improvements in preparation for upcoming
features.
Changes summary:
- Additional error types.
- Clearer documentation.
- Improved C++ compatibility.
- Exhaustive RSS action.
- Consistent behavior of VLAN pattern item.
- New "transfer" attribute bringing consistency to VF/PF pattern items.
- Confusing "PORT" pattern item renamed "PHY_PORT", with new action
counterpart.
- New "PORT_ID" pattern item and action to be used with port representors.
This series piggybacks on the major ABI update introduced by a prior
commit [4] for DPDK 18.05 and depends on several fixes [5] which must be
applied first.
[1] "[RFC] Switch device offload with DPDK"
http://dpdk.org/ml/archives/dev/2018-March/092513.html
[2] commit 676b605182a5 ("doc: announce ethdev API change for RSS
configuration")
[3] "[PATCH v1 00/21] MLX5 tunnel Rx offloading"
http://dpdk.org/ml/archives/dev/2018-March/092264.html
[4] commit 653e038efc9b ("ethdev: remove versioning of filter control
function")
[5] "[PATCH v6 00/11] Bunch of flow API-related fixes"
http://dpdk.org/ml/archives/dev/2018-April/098035.html
v5 changes:
- Fixed errors reported by GCC and Clang in patch 05/16 ("ethdev: alter
behavior of flow API actions").
- Rebased series once again.
v4 changes:
- No change besides new acked-by lines, rebased series to address conflicts.
v3 changes:
- Rebased series, fixed latest conflicts.
- Addressed Andrew's comments, see affected patches for details:
- Empty RSS types in flow rule means PMD-specific RSS instead of no RSS.
- RSS hash function now explicitly compared against
RTE_ETH_HASH_FUNCTION_DEFAULT instead of 0 in all PMDs.
- sfc PMD updated to also accept Toeplitz.
- Implicit VLAN TPID matching now removed from all PMDs.
- Default mask upate for VLAN TCI now split as separate patch #11.
- Ingress/egress definition clarified in patch #12.
v2 changes:
- Squashed "ethdev: update ABI for flow API functions" in subsequent
patches.
- Emphasized ABI impact in relevant commit logs.
- Modified documentation in "ethdev: alter behavior of flow API actions" to
describe how terminating flow rules without any action of the fate kind
result in undefined behavior instead of dropping traffic.
- Fixed other minor documentation formatting issues.
- Modified "ethdev: refine TPID handling in flow API" as follows:
- Using standard macro definitions for VLAN, QinQ and E-Tag EtherTypes.
- Fixed endian conversion in sfc.
- Replaced a condition in VLAN pattern item processing with an assertion
check for i40e.

Upcoming changes in relation to the handling of actions list will make the
DUP action redundant as specifying several QUEUE actions will achieve the
same behavior. Besides, no PMD implements this action.
By removing an entry from enum rte_flow_action_type, this patch breaks ABI
compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

This patch makes the following changes to flow rule actions:
- List order now matters, they are redefined as performed first to last
instead of "all simultaneously".
- Repeated actions are now supported (e.g. specifying QUEUE multiple times
now duplicates traffic among them). Previously only the last action of
any given kind was taken into account.
- No more distinction between terminating/non-terminating/meta actions.
Flow rules themselves are now defined as always terminating unless a
PASSTHRU action is specified.
These changes alter the behavior of flow rules in corner cases in order to
prepare the flow API for actions that modify traffic contents or properties
(e.g. encapsulation, compression) and for which order matter when combined.
Previously one would have to do so through multiple flow rules by combining
PASSTRHU with priority levels, however this proved overly complex to
implement at the PMD level, hence this simpler approach.
This breaks ABI compatibility for the following public functions:
- rte_flow_create()
- rte_flow_validate()
PMDs with rte_flow support are modified accordingly:
- bnxt: no change, implementation already forbids multiple actions and does
not support PASSTHRU.
- e1000: no change, same as bnxt.
- enic: modified to forbid redundant actions, no support for default drop.
- failsafe: no change needed.
- i40e: no change, implementation already forbids multiple actions.
- ixgbe: same as i40e.
- mlx4: modified to forbid multiple fate-deciding actions and drop when
unspecified.
- mlx5: same as mlx4, with other redundant actions also forbidden.
- sfc: same as mlx4.
- tap: implementation already complies with the new behavior except for
the default pass-through modified as a default drop.

From: Adrien Mazarguil @ 2018-04-19 10:16 UTC (permalink / raw)
To: Thomas Monjalon, Ferruh Yigit, dev
This patch replaces C99-style flexible arrays in struct rte_flow_action_rss
and struct rte_flow_item_raw with standard pointers to the same data.
They proved difficult to use in the field (e.g. no possibility of static
initialization) and unsuitable for C++ applications.
Affected PMDs and examples are updated accordingly.
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

Since its inception, the rte_flow RSS action has been relying in part on
external struct rte_eth_rss_conf for compatibility with the legacy RSS API.
This structure lacks parameters such as the hash algorithm to use, and more
recently, a method to tell which layer RSS should be performed on [1].
Given struct rte_eth_rss_conf will never be flexible enough to represent a
complete RSS configuration (e.g. RETA table), this patch supersedes it by
extending the rte_flow RSS action directly.
A subsequent patch will add a field to use a non-default RSS hash
algorithm. To that end, a field named "types" replaces the field formerly
known as "rss_hf" and standing for "RSS hash functions" as it was
confusing. Actual RSS hash function types are defined by enum
rte_eth_hash_function.
This patch updates all PMDs and example applications accordingly.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

configuration")

v3 changes:
Documentation update regarding the meaning of a 0 value for RSS types in
flow rules.
It used to implicitly mean "no RSS" but is redefined as requesting a kind
of "best-effort" mode from PMDs, i.e. anything ranging from empty to
all-inclusive RSS; what matters is it provides safe defaults that will work
regardless of PMD capabilities.

By definition, RSS involves some kind of hash algorithm, usually Toeplitz.
Until now it could not be modified on a flow rule basis and PMDs had to
always assume RTE_ETH_HASH_FUNCTION_DEFAULT, which remains the default
behavior when unspecified (0).
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

v3 changes:
- Although RTE_ETH_HASH_FUNCTION_DEFAULT is defined as 0, made comparisons
more explicit where doing so would clarify the code.
- Updated sfc to include Toeplitz as the other allowed value.
Both according to Andrew's suggestions [1].

RSS hash types (ETH_RSS_* macros defined in rte_ethdev.h) describe the
protocol header fields of a packet that must be taken into account while
computing RSS.
When facing encapsulated (e.g. tunneled) packets, there is an ambiguity as
to whether these should apply to inner or outer packets. Applications need
the ability to tell exactly "where" RSS must be performed.
This is addressed by adding encapsulation level information to the RSS flow
action. Its default value is 0 and stands for the usual unspecified
behavior. Other values provide a specific encapsulation level.
Contrary to the change announced by commit 676b605182a5 ("doc: announce
ethdev API change for RSS configuration"), this patch does not affect
struct rte_eth_rss_conf but struct rte_flow_action_rss as the former is not
used anymore by the RSS flow action. ABI impact is therefore limited to
rte_flow.
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

TPID handling in rte_flow VLAN and E_TAG pattern item definitions is not
consistent with the normal stacking order of pattern items, which is
confusing to applications.
Problem is that when followed by one of these layers, the EtherType field
of the preceding layer keeps its "inner" definition, and the "outer" TPID
is provided by the subsequent layer, the reverse of how a packet looks like
on the wire:
Wire: [ ETH TPID = A | VLAN EtherType = B | B DATA ]
rte_flow: [ ETH EtherType = B | VLAN TPID = A | B DATA ]
Worse, when QinQ is involved, the stacking order of VLAN layers is
unspecified. It is unclear whether it should be reversed (innermost to
outermost) as well given TPID applies to the previous layer:
Wire: [ ETH TPID = A | VLAN TPID = B | VLAN EtherType = C | C DATA ]
rte_flow 1: [ ETH EtherType = C | VLAN TPID = B | VLAN TPID = A | C DATA ]
rte_flow 2: [ ETH EtherType = C | VLAN TPID = A | VLAN TPID = B | C DATA ]
While specifying EtherType/TPID is hopefully rarely necessary, the stacking
order in case of QinQ and the lack of documentation remain an issue.
This patch replaces TPID in the VLAN pattern item with an inner
EtherType/TPID as is usually done everywhere else (e.g. struct vlan_hdr),
clarifies documentation and updates all relevant code.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()
Summary of changes for PMDs that implement ETH, VLAN or E_TAG pattern
items:
- bnxt: EtherType matching is supported with and without VLAN, but TPID
matching is not and triggers an error.
- e1000: EtherType matching is only supported with the ETHERTYPE filter,
which does not support VLAN matching, therefore no impact.
- enic: same as bnxt.
- i40e: same as bnxt with existing FDIR limitations on allowed EtherType
values. The remaining filter types (VXLAN, NVGRE, QINQ) do not support
EtherType matching.
- ixgbe: same as e1000, with additional minor change to rely on the new
E-Tag macro definition.
- mlx4: EtherType/TPID matching is not supported, no impact.
- mlx5: same as bnxt.
- mvpp2: same as bnxt.
- sfc: same as bnxt.
- tap: same as bnxt.

v3 changes:
Updated mrvl to mvpp2.
Moved unrelated default TCI mask update to separate patch.
Fixed sfc according to Andrew's comments [1], which made so much sense that
I standardized on the same behavior for all other PMDs: matching outer TPID
is never supported when a VLAN pattern item is present.
This is done because many devices accept several TPIDs but do not provide
means to match a given one explicitly, it's all or nothing, and that makes
the resulting flow rule inaccurate.

To: Thomas Monjalon, Ferruh Yigit, dev; +Cc: Andrew Rybchenko
This new attribute enables applications to create flow rules that do not
simply match traffic whose origin is specified in the pattern (e.g. some
non-default physical port or VF), but actively affect it by applying the
flow rule at the lowest possible level in the underlying device.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_validate()
Signed-off-by: Adrien Mazarguil <adrien.mazarguil@6wind.com>

v3 changes:
Clarified definition for ingress and egress following Andrew's comment on
subsequent patch.

Specifying both directions at once for a given rule is not recommended but
may be valid in a few cases (e.g. shared counters).
+Attribute: Transfer
+^^^^^^^^^^^^^^^^^^^
+
+Instead of simply matching the properties of traffic as it would appear on a
+given DPDK port ID, enabling this attribute transfers a flow rule to the
+lowest possible level of any device endpoints found in the pattern.
+
+When supported, this effectively enables an application to reroute traffic
+not necessarily intended for it (e.g. coming from or addressed to different
+physical ports, VFs or applications) at the device level.
+
+It complements the behavior of some pattern items such as `Item: PORT`_ and
+is meaningless without them.
+
+When transferring flow rules, **ingress** and **egress** attributes
+(`Attribute: Traffic direction`_) keep their original meaning, as if
+processing traffic emitted or received by the application.

Contrary to all other pattern items, these are inconsistently documented as
affecting traffic instead of simply matching its origin, without provision
for the latter.
This commit clarifies documentation and updates PMDs since the original
behavior now has to be explicitly requested using the new transfer
attribute.
It breaks ABI compatibility for the following public functions:
- rte_flow_create()
- rte_flow_validate()
Impacted PMDs are bnxt and i40e, for which the VF pattern item is now only
supported when a transfer attribute is also present.

While RTE_FLOW_ITEM_TYPE_PORT refers to physical ports of the underlying
device using specific identifiers, these are often confused with DPDK port
IDs exposed to applications in the global name space.
Since this pattern item is seldom used, rename it RTE_FLOW_ITEM_PHY_PORT
for better clarity.
No ABI impact.

This patch adds the missing action counterpart to the PHY_PORT pattern
item, that is, the ability to directly inject matching traffic into a
physical port of the underlying device.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

RTE_FLOW_ACTION_TYPE_PORT_ID brings the ability to inject matching traffic
into a different device, as identified by its DPDK port ID.
This is normally only supported when the target port ID has some kind of
relationship with the port ID the flow rule is created against, such as
being exposed by a common physical device (e.g. a different port of an
Ethernet switch).
The converse pattern item, RTE_FLOW_ITEM_TYPE_PORT_ID, makes the resulting
flow rule match traffic whose origin is the specified port ID. Note that
specifying a port ID that differs from the one the flow rule is created
against is normally meaningless (if even accepted), but can make sense if
combined with the transfer attribute.
These must not be confused with their PHY_PORT counterparts, which refer to
physical ports using device-specific indices, but unlike PORT_ID are not
necessarily tied to DPDK port IDs.
This breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

This patch provides the same functionality and supersedes Qi Zhang's
"ether: add flow action to redirect packet to a port" [1].
The main differences are:
- Action is named PORT_ID instead of PORT.
- Addition of a PORT_ID pattern item.
- More extensive documentation.
- Testpmd support.
- rte_flow_copy() support.

You should have rebased this series including this patch on top of mine
([1] followed by [2]) to avoid some mistakes such as documenting
"terminating actions".
This patch could also update documentation for flow rules [3] groups [4] and
priorities [5] to make clear that groups aren't linked by default, their
order doesn't matter and explicit JUMP actions are needed to reach them
(actually look for every instance of the word "group" in this
documentation).
Also the addition of an action in the middle of the enum has an ABI impact,
please put a reminder in the commit log as in [6].
More below.

Since there are no more "terminating" actions, you should document that it
will cause traffic to be processed by flow rules found in the target group.
Also I think you should put emphasis on undefined behavior:
- Targeting a group that doesn't include any flow rule.
- Triggering loops.

Since struct rte_flow_action_jump provides complete documentation, no need

Remember to synchronize this paragraph after making changes to rte_flow.rst.
Here you can also provide more info regarding undefined behavior (useful in
Doxygen format for application writers).

You should move this definition before "struct rte_flow_action_mark" to keep
the same definition order as in the enum.

A rewrite of commit message is in order, i think :) Something like this:
Change some functions' return type from void to int. This will not break
ABI because they are internal only.
(see below for comments on lcore changes)

Again, please do not add patch/version notes to the commit message, put
them after "---". Version history is not for commit messages, it's for
people reviewing it before merge.

It seems like you're mixing two different patchsets here. Maybe it would
be beneficial to put lcore changes in a separate patch? Technically,
rte_panic's in lcore are not part of init sequence.
(also, should panic state be volatile?)

Hi Changpeng, Tomasz,
Any chance that you resubmit the series now that the Qemu changes adding
a protocol feature flag has been accepted?
Cheers,
Maxime

Copy on the commit message and volatile.
Regarding the new function defunct_and_remain_in_endless_loop ()
I don't think I can put that in a separate patch without breaking the
current patch independence.

* [dpdk-dev] [PATCH v2] cmdline: rework as a wrapper to libedit

Disclaimer: this patch must not be confused with the CLI library [1]
(work in progress) that will eventually supersede librte_cmdline itself
with a different API.
Rather, it modifies librte_cmdline to delegate all the heavy lifting
(terminal and history handling), strips unused features and re-implements
what remains of its public API as a wrapper to the editline library (also
known as libedit) [2], a well-known, BSD-licensed and widely available
library used by many projects which does everything needed and more [3].
This approach was chosen because converting librte_cmdline as a wrapper to
a more capable library was easier and faster than addressing its
shortcomings and results in much less code to maintain in DPDK.
It also provides a drop-in solution for applications that rely on
librte_cmdline. They benefit from greatly improved command line handling
without a meaningful impact on their code base.
The main motivation behind this patch is testpmd's flow (rte_flow) command,
which requires support for dynamic tokens and very long lines that must be
broken down when displayed. This is not supported by librte_cmdline's
limited terminal handling capabilities, resulting in a rather frustrating
user experience.
It had to be addressed given the importance of testpmd as one of the
primary tool used by PMD developers.
This rework results in the following changes:
- Removed circular buffer management interface for command history
(cmdline_cirbuf.c), command history being handled by libedit.
- Removed raw command-line interpreter (cmdline_rdline.c).
- Removed raw terminal handler (cmdline_vt100.c).
- Removed all test/example code for the above.
- Re-implemented high level interactive and non-interactive command-line
handlers (cmdline.c and cmdline_socket.c) on top of libedit using its
native interface, not its readline compatibility layer.
- Made struct cmdline opaque so that applications relying on librte_cmdline
do not need to include any libedit headers.
- Applications do not need to include cmdline_rdline.h anymore.
- Terminal resizing is now automatically handled.
- New external dependency for applications relying on librte_cmdline.
- Major version bump due to the ABI impact of these changes.

v2 changes:
- Replaced an instance of snprintf() with rte_strlcpy() [5].
- Rebased patch.
[5] http://dpdk.org/ml/archives/dev/2018-April/097721.html
v1 changes:
No fundamental change since the original RFC [4], except it's been rebased
several times and Meson build support was added in the meantime. Commit log
was also shortened a bit.
I'm re-sending this because I think it's useful, at least to me (duh). As
the maintainer of rte_flow, I spend most of my time typing flow commands in
testpmd and libedit makes that a pleasant experience.
Try it out! And don't hesitate to send your acked-by line to get this in
time for 18.05 :)

- * This file is a small equivalent to the GNU readline library, but it
- * was originally designed for small systems, like Atmel AVR
- * microcontrollers (8 bits). Indeed, we don't use any malloc that is
- * sometimes not implemented (or just not recommended) on such
- * systems.
- *
- * Obviously, it does not support as many things as the GNU readline,
- * but at least it supports some interesting features like a kill
- * buffer and a command history.
- *
- * It also have a feature that does not have the GNU readline (as far
- * as I know): we can have several instances of it running at the same
- * time, even on a monothread program, since it works with callbacks.
- *
- * The lib is designed for a client-side or a server-side use:
- * - server-side: the server receives all data from a socket, including
- * control chars, like arrows, tabulations, ... The client is
- * very simple, it can be a telnet or a minicom through a serial line.
- * - client-side: the client receives its data through its stdin for
- * instance.

As discussed privately, at first glance I was a bit reticent to
introduce a new API in mempool that will only be available in one
mempool driver.
There have been the same debate for several features of ethdev: should
we provide a generic API for a feature available in only one driver? Or
should the driver provide its own API?
Given that the mempool driver API is not that big currently, and that it
can bring a performance enhancement (which is the primary goal of DPDK),
I think we can give a chance to this patchset. Drivers that want to use
this new bucket driver can take advantage of the new API, keeping a
fallback mode to still be working with other mempool drivers.
The bet is:
- drivers and aplication try the bucket driver and its new API, and
they notice a performance increase
- the get_contig_block API is implemented in some other drivers, if
possible (not easy for default one at least)
- the bucket driver could become the default driver, if the performance
increase is significant and wide.
By integrating this patchset, I hope we can also have some feedback
about the performance of this driver in other situations. My worries are
about pipeline+multicore use-cases, where it may add some pressure
(races conditions?) on the bucket header.
Finally, I think (as discussed privately) that the tests should be
updated to be able to reproduce the tests in this cover letter. I just
did a quick test by replacing "stack" by "bucket" in autotest (see patch
below) and it fails in populate(). I did not investigate more, maybe the
parameters are not correct for bucket.

I think it's a good idea to have a way to query mempool features
or parameters. The approach chosen in this patch looks similar
to what we have with ethdev devinfo, right?

Thinking in terms of ABI compatibility, it looks that each time we will
add or remove a field, it will break the ABI because the info structure
will change.
Well, it's maybe nitpicking, because most of the time adding a field in
info structure goes with adding a field in the mempool struct, which
will anyway break the ABI.
Another approach is to have a function
rte_mempool_info_contig_block_size(mp) whose ABI can be more easily
wrapped with VERSION_SYMBOL().
On my side I'm fine with your current approach, especially given how few
usages of VERSION_SYMBOL() we can find in DPDK. But in case you feel
it's better to have a function...

it's more consistent with the rest of the function to do,
if(activate_slave(bonded_eth_dev, port_id))
return rc;
There's other places through the patches where "!= 0" is used but not
really needed

You don't need "!= 0"
You need to set "error" here, or else return it from igb_pf_host_init().
We know -ENOMEM is the only error that can be returned from
igb_pf_host_init() but not sure if should assume that.

Previously, it wasn't possible for mem_cfg_fd to be reused after a
failure. Now it is - please reset it to -1. in these close conditions.

Again, previously this would have aborted on a failure. So it needs to
be reset to a value that allows retry.

Use rte_eal_init_alert to indicate why you are failing the init.

How are you cleaning up the threads that were spawned? Lets say this
loop will execute 5 times, and on the 3rd entry, these errors happen.
You now leave DPDK 'half-initialized' - you've spun up threads and
allocated memory.
Also, again use rte_eal_init_alert(). It was added for a reason :)

Same question as before. If pthread_create is failing, there are worse
problems than aborting.

This is worse than a panic. Users will blame applications for appearing
to freeze. Please leave the panics in place rather than do this.

I'm not even sure this check has merit, tbh. Is there ever a chance for
an lcore thread to be spawned like this? Probably a better patch would
just remove all the code you've inserted, but keep the check you
removed.

Same question. Actually this could happen on shutdown, I think? If
there's a race where the pipe is torn down before the thread? Not sure
if there are any ordering guarantees around that.

I don't see how any of this is better for the user. In fact, I think
this is worse because it will make portions of the application stop
working without any way to move forward. rte_panic() will at least give
the process a chance to recover from a potentially ephemeral condition.

This seems to only exist as a way of triggering the run_once check in
the eal_init. It doesn't add anything except one more state variable to
check against. What is the purpose?
Further, it seems unrelated to removing panics.

I see. You know, I think adding 20+ focused actions would be fine actually,
easier to document, report as HW capabilities and to use by applications
(e.g. see issue you raise about adding testpmd support below).
In all the protocols you mention, is the device able to really update *all*
fields or only the "usual" set? IPv4 src/dst probably, now what about ToS,
packet ID, fragment offset and so on? Same for other protocols, should we
care about protocol fields that applications rarely set (if at all),
especially if no device can update them?
> For testpmd support, Seems there is no reference to enable an action with void parameters, so it may take me time to figure out a solution,
Dedicated actions on the other hand should be way easier to add :)

I know, there are several problematic actions without testpmd
support. However those are often associated with experimental APIs and may
be modified without prior notice.
Keep in mind there is no need to rush. Adding rte_flow actions doesn't hurt
ABI and can be done for any DPDK release, even part of the same series as
the first PMD implementation which must be validated somehow (no one ever
submits code that can't be tested, right?), this is why testpmd support is
mandatory.

It is getting messier! [1]
Hi Thomas,
Any suggestion on how to manage these rte_flow patches, we are late and they
aren't settle down yet. There are some level of dependency and there are some
uncertainty in some of the dependent patches because of ABI/API process.
It would be great to get them incremental or have a plan to how to proceed.
[1]
Previous version in this thread is following patches:
[PATCH v4 1/2] ethdev: add supported hash function check
[PATCH v4 2/2] app/testpmd: new parameter for port config all rss command
And this set is:
[PATCH v5 1/2] ethdev: introduce generic IP/UDP tunnel checksum and TSO
[PATCH v5 2/2] app/testpmd: testpmd support Tx generic tunnel offloads
But there is already v5 send for this set and in other thread there is v7 of it:
[PATCH v7 0/2] support Tx generic tunnel checksum and TSO
[PATCH v7 1/2] ethdev: introduce generic IP/UDP tunnel checksum and TSO
[PATCH v7 2/2] app/testpmd: testpmd support Tx generic tunnel offloads
Most probably you have intended to send another patchset here.

I was probably too eager to get rid of this panic taking some wrong
assumptions on the way the library will be called.
Removing the panic from the thread is obviously more complex and also ABI
breaking.

I will revert back to panicing on this patchset
and aim for the thread in the next build.

Actually this is not a run-once in purpose, rather an attempt to define a
state for the device
and on the way work around breaking abi on the the void function called
before that.

Please just use run_once. That's a better way of preventing this.

Involved parties looks like following:
Xueming: Mellanox offloads for tunnel protocols.
Adrien: rte_flow improvements for rss?
Qi: rte_flow more protocol support?
Declan/Awal: TEP, port representor, using rte_flow?
Andrew: sfc PMD updates on top of rte_flow changes.
Gaetan: devargs, previously devargs dependency mentioned for some of above, not
sure that is still the case.
I am not clear of latest status above patches and their dependency with
eachother, are they in sync or not, it can be nice who know clarifies more.

Looking at the eal_thread_init_master, I think it's probably a
recoverable condition. For instance, perhaps the core mask was wrong,
and could be corrected by re-attempting the initialization. Just
suggesting that it's probably okay to allow a re-attempt here. I would
suggest:
- eal_thread_init_master(rte_config.master_lcore);
+ if (eal_thread_init_master(rte_config.master_lcore) != 0) {
+ rte_eal_init_alert("Cannot assign master lcore\n");
+ rte_errno = EINVAL;
+ return -1;
+ }
if you agree.

I see. Most likely you'll need a proper initialization protocol both
ways. As a brief example, you'll need something to guarantee the thread
state (just a general outline):
--
global_initial_state = UNINIT
pthread_init_cond = PTHREAD_COND_INIT;
global_spawned_ctr = atomic_ctr(0);
rte_eal_init()
...
global_initial_state = INITIALIZING
thread_ctr = 0;
...
for_each_lcore()
spawn_thread()
if (spawn_fails)
global_initial_state = UNINIT;
pthread_cond_broadcast()
return error
thread_ctr++;
while (thread_ctr != global_spawned_ctr)
/* wait? figure out when to declare extreme failure */
global_initial_state = THREAD_INITIALIZED
pthread_cond_broadcast(pthread_init_cond)
while (thread_ctr)
wait_some_grace_period()
for_each_lcore_thread()
thread_state = lcore_state[thr]; /* probably needs a mem barrier*/
if (thread_state != THREAD_READY && thread_state != THREAD_STARTING)
/* failure - message all threads to clean up */
if (thread_state == THREAD_READY)
thread_ctr--;
in eal_thread_loop():
/* before even the set_affinity */
atomic_inc(global_spawned_ctr);
lcore_state[thr] = THREAD_STARTING;
pthread_cond_wait(pthread_init_cond)
if (global_initial_state != THREAD_INITIALIZED)
lcore_state[thr] = THREAD_FAILED;
return...;
/* do all the normal checks... instead of the panic_state, just set
lcore_state[thr] to THREAD_FAILED, clean up any additional
allocated resources, and return... which will exit the thread */
lcore_state[thr] = THREAD_READY;
--
In the above I hope it illustrates what you'll need - a way to signal to
each side that initialization phase is happening, and that
initialization was successful / failed, and to clean up in the failure
case.
Just meant for illustration so feel free to ignore / flame, but that's
how I would go about removing the rte_panic() calls.

I think it's a way to try and track state for initialization and to
prevent future inits. Which ABI are you worried about? rte_panic()?
I'm not sure how this is an ABI work around, but I'm probably not
thinking about it hard enough.

Adding new entry in the middle could break ABI compatibility. So moving
it to the end.

There is still the issue about returning this wrong bits in the mbuf.
Bit in the mbuf ptypes must only reflect what is present in the mbuf,
using RTE_PTYPE_TUNNEL_MASK means all tunnels are present in the packet
which is absolutely wrong.
This behavior was not announce and breaks API/ABI. It cannot be
accepted yet.
I'll suggest to add a new RTE_PTYPE_TUNNEL_UNKNOWN which does not break
the ABI or don't add such bits in the mbuf.

I now see the mess I did and why wasn't it clear.
I initially changed the api of eal_thread_init_master() from void to int.
Having had the ABI check failed, I only fixed the linuxapp back to void and
added this workaround to prevent ABI break on this patch.
I will align both linuxapp and bsd to remain at panic for this function as
well , and address it together with the thread itself

This is still needed for QUEUE action, Verbs refuses to create an hash
Rx queue if no RSS key is provided even if the hash field is 0.
This can be fully moved to mlx5_hrxq_new() who can use the default key
when the rss_key is not provided.

Add jump action type which defines an action which allows a matched
flow to be redirect to the specified group. This allows physical and
logical flow table/group hierarchies to be defined through rte_flow.
This breaks ABI compatibility for the following public functions (as it
modifes the ordering of the rte_flow_action_type enumeration):
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()
Add support for specification of new JUMP action to testpmd's flow
cli, and update the testpmd documentation to describe this new
action.

I'm wondering if "As refcnt of a direct mbuf is at least 2" should be
clarified. I guess we are talking about a direct mbuf that has another one
attached too.
I'm also not sure if I understand properly: to me, it is possible to have
an indirect mbuf that references a direct mbuf with a refcount of 1:
m = rte_pktmbuf_alloc()
mi = rte_pktmbuf_alloc()
rte_pktmbuf_attach(mi, m)
rte_pktmbuf_free(m)

It looks that only refcnt_atomic is used.
I don't know if we really need the non-atomic one yet.

I'm a bit reticent to have RTE_MBUF_DIRECT(m) different of
!RTE_MBUF_INDIRECT(m), I feel it's not very natural.
What about:
- direct = embeds its own data
- clone (or another name) = data is another mbuf
- extbuf = data is in an external buffer

This forces to have the shared data at the end of the buffer. Is it
always possible? I think there are use-cases where the user may want to
specify another location for it.
For instance, an application mmaps a big file (locked in memory), and
wants to send mbufs pointing to this data without doing any copy.
Maybe adding a m->shinfo field would be a better choice, what do you
think?
This would certainly break the ABI, but I wonder if that patch does
not already break it. I mean, how would react an application compiled
for 18.02 if an EXTBUF is passed to it, knowing that many functions
are inline?

Agree with Konstantin's comment. I think buf_iova should be an argument
of the function.
> + m->buf_len = RTE_PTR_DIFF(shinfo, buf_addr);
Related to what I said above: I think m->buf_len should be set to
the buf_len argument, so a user can point to existing read-only
data.
[...]
Few more comments:
I think we still need to find a good way to advertise to the users
if a mbuf is writable or readable. Today, the rules are quite implicit.
There are surely some use cases where the mbuf is indirect but with
only one active user, meaning it could be READ-WRITE. We could target
18.08 for this.
One side question about your implementation in mlx. I guess the
hardware will write the mbuf data in a big contiguous buffer like
this:
+-------+--------------+--------+--------------+--------+- - -
| |mbuf1 data | |mbuf2 data | |
| | | | | |
+-------+--------------+--------+--------------+--------+- - -
Which will be transformed in:
+--+----+--------------+---+----+--------------+---+---+- - -
| |head|mbuf1 data |sh |head|mbuf2 data |sh | |
| |room| |inf|room| |inf| |
+--+----+--------------+---+----+--------------+---+---+- - -
So, there is one shinfo (i.e one refcount) for each mbuf.
How do you know when the big buffer is not used anymore?
To summarize, I like the idea of your patchset, this is close to
what I had in mind... which does not necessarly mean it is the good
way to do ;)
I'm a bit afraid about ABI breakage, we need to check that a
18.02-compiled application still works well with this change.
About testing, I don't know if you checked the mbuf autotests,
but it could also help to check that basic stuff still work.
Thanks,
Olivier

Change some local functions return type from void to int.
This change does not break ABI as the functions are internal.
Panic thrown from threads was not handled in this patch

Aren't devargs intended to be internal and not part of ABI.
If so maybe the experimental tag is not necessary, and you
want to say that in the comments.

Very good point. Will make rte_pktmbuf_attach_extbuf() take *shinfo as an
argument.

I like it to store in mbuf too.

Even if I add shinfo field in rte_mbuf, I think it won't break the ABI. The
second cacheline is just 40B and it would simply make it 48B. Some code might
check the order/size of some fields (e.g. vPMD) in the struct, but if it is
added at the end of the struct, it should be okay. And there's no need to make a
change in a C file for this.

Oops, that was my silly mistake. I just copied this block from
rte_pktmbuf_init(). Then, I wanted to change it to rte_malloc_virt2iova() but I
forgot. I didn't realized it during my tests because mlx devices don't use iova
but virtaddr.
If it takes iova as an argument instead, it can be faster and it can use 'real'
external memory for packet DMA, e.g. storage application you mentioned. I mean,
even if a buffer isn't allocated inside DPDK (doesn't belong to one of memseg
list), this should work. Good suggestion!

I will make a change to have an argument of extra memory for shared data. And if
shinfo is passed as NULL, it will still spare bytes at the end, just for
convenience.

Right. That'll be very good to have.

Metadata for the whole chunk, having another refcnt managed by PMD.
fcb_opaque will have this pointer so that the callback func knows it.

I had the same concern so I made rte_pktmbuf_attach_extbuf() __rte_experimental.
Although this new ol_flag is introduced, it can only be set by the new API and
the rest of changes won't be effective unless this flag is set.
RTE_MBUF_HAS_EXTBUF() will always be false if -DALLOW_EXPERIMENTAL_API isn't
specified or rte_pktmbuf_attach_extbuf() isn't called. And there's no change
needed in a C file. For this reason, I don't think there's ABI breakage.
Sounds correct?

I'll make sure all the tests pass before I submit a new version.
Thanks,

The ABI is exposed, so any third-party declaring rte_devargs would be
impacted by changes to the structure. I don't think it's internal.
In any case, the API itself is not internal, and the rte_experimental
tag is meant for API I think? This function is new and prone to changes
as well as part of the public EAL API, I think it is correct to tag it
experimental.

Hmm, imagine you compile an application on top of 18.02.
Then, you update your dpdk libraries to 18.05.
The mlx driver may send mbufs pointing to an external buffer to the
application. When the application will call the mbuf free function, it
will probably not do the expected work, because most of the functions
involved are inline. So, to me this is an ABI breakage.
This is not a technical issue, since the ABI of mbuf will already be
broken this release (control mbuf removed). This is more a process
question, because an ABI breakage and its area should be announced.

* [dpdk-dev] [PATCH v2 3/5] eal: make eal_log_level save private

We don't want format of eal log level saved values to be visible
in ABI. Move to private storage in eal_common_log.
Includes minor optimization. Compile the regular expression for
each log match once, rather than each time it is used.

In any case, there will be an ABI change, because an application
compiled for 18.02 will not be able to handle these new kind of
mbuf.
So unfortunatly yes, I think this kind of changes should first be
announced.

OK I got it.
I think both approach could make sense:
- one shinfo per huge buffer
- or one shinfo per mbuf, and use the callback to manage another refcnt
(like what Yongseok described)
So I agree with your proposal, shinfo should be initialized by
the caller if it is != NULL, else it can be initialized by
rte_pktmbuf_attach_extbuf().

I would prefer to have only 2 reference counters, one in the mbuf
and one in the shinfo.

What is the impact for the application developer?
Is there something to change in the application after this patch?

Let me address two concerns discussed here.
1) API breakage of RTE_MBUF_DIRECT()
Previously, direct == !indirect but now direct == !indirect && !extbuf. But to
set the new flag (EXT_ATTACHED_MBUF), the new API, rte_pktmbuf_attach_extbuf()
should be used and it is experimental. If application isn't compiled without
allowing experimental API or application doesn't use the new API, it is always
true that direct == !indirect. It looks logically okay to me. And FYI, it passed
the mbuf_autotest.
2) ABI breakage of mlx5's new Multi-Packet RQ (a.k.a MPRQ) feature
It's right that it could breadk ABI if the PMD delivers packets with external
buffer attached. But, the MPRQ feature is disabled by default and it can be
enabled only by the newly introduced PMD parameter (mprq_en). So, there's no
possibility that 18.02-based application receives a mbuf having an external
buffer. And, like Olivier mentioned, there's another ABI breakage by removing
control mbuf anyway.
So, I don't think there's need for developers to change their application after
this patch unless they want to use the new feature.
Thanks,
Yongseok

To summarize, this a feature addition, there is no breakage.
So I don't see what should be announced.
I think it could be integrated as experimental with a first
PMD implementation in 18.05. It will allow to test the feature
in the field, and have more feedbacks about how to improve the API.

* [dpdk-dev] [PATCH v3 3/5] eal: make eal_log_level save private

We don't want format of eal log level saved values to be visible
in ABI. Move to private storage in eal_common_log.
Includes minor optimization. Compile the regular expression for
each log match once, rather than each time it is used.

Stricly speaking, it is possible that a user pass this parameter through
the application (which just forwards it) to the new dpdk. So there is an ABI
change. In short, if a user wants to enable an optimization of 18.05 on an
application compiled for 18.02, it will fail.
But I agree the impact is very limited.
We are a bit lucky, because:
- the mbuf size is aligned to 128, so it stays the same, and the priv area
is after the 2nd cache line (note: we are at 112 bytes over 128 on x86_64).
- previously, the area where shinfo is added was filled with garbage. It has
no impact because it is only accessed when the EXT flag is set.
- the unused flags are 0 by default.
Knowing there is an ABI breakage this release, it could also make sense to
try to limitate them and avoid breaking it again in 18.08.
So in my opinion, reagarding API/ABI, this patchset could go in for 18.05.

I'd prefer to keep current solution. Otherwise it could result in too many
different functions to get various information about mempool driver
features/characteristics. Also it could be not very convenient to get
many parameters.
May be we should align info structure size to cache line to avoid size
changes in many cases? Typically it will be used on slow path and
located on caller stack and adding some bytes more should not
be a problem.

Getting some build errors [1], it seems some samples are using some other
experimental APIs so that we can't remove the flag for them.

Yes, that could be a good thing to do.

I have prepared this patch on master.
Please can you fix it when applying?
