Matan Azrad [Sun, 3 Sep 2017 13:19:07 +0000 (16:19 +0300)]
app/testpmd: fix forward port ids setting

The corrupted code didn't check the port availability when
it was trying to set the forward port IDs array.
However, when it was counting the number of ports, the availability
was checked by RTE_ETH_FOREACH_DEV iterator.

Hence, even when ETH devices ports were not in ATTACHED state,
the testpmd tried to forward traffic by them and got segmentation
fault at queue access time.

For example:
When EAL command line parameters include two devices, the first
is failsafe with two sub devices and the second is any device,
testpmd gets two devices by the iterator and sets for forwarding
both, the failsafe device and the failsafe first sub device
(instead of the second sub device).
After the first failsafe sub device state was changed to DEFERRED,
testpmd tries to forward traffic through the deferred device
because it didn't check the port availability in setting time.

The fix uses the RTE_ETH_FOREACH_DEV iterator for the forward
port IDs default setting.

net/qede/base: fix for VF malicious indication

IOV regression testing led to discovery of a minor issue + possibly race
in IOV flows:
 a. Malicious indications in VF-database on PF-side get cleared during
    FLR flows - but not when disabling SRIOV. At least in Linux if you
    disable IOV while having a malicious VF you wouldn't be able to
    clear the indication as driver would prevent from initializing it.
 b. Possible race during PF response to VF - the channel is made ready
    only after sending the rc via dmae to VF. It's possible due to
    context switch at end of DMAE [when releasing Mutex] that VF would
    start running and send another message prior to PF clearing the
    channel, making the FW consider that VF to be malicious.

This patch fixes that by
 - clearing the indication even if we're only going to disable VF
 - resetting the channel to ready before PF copies the rc to the VF, PF
   can then continue and send an additional message

7 years agogso: add Generic Segmentation Offload API framework
Jiayu Hu [Sat, 7 Oct 2017 14:56:39 +0000 (22:56 +0800)]
gso: add Generic Segmentation Offload API framework

Generic Segmentation Offload (GSO) is a SW technique to split large
packets into small ones. Akin to TSO, GSO enables applications to
operate on large packets, thus reducing per-packet processing overhead.

To enable more flexibility to applications, DPDK GSO is implemented
as a standalone library. Applications explicitly use the GSO library
to segment packets. To segment a packet requires two steps. The first
is to set proper flags to mbuf->ol_flags, where the flags are the same
as that of TSO. The second is to call the segmentation API,
rte_gso_segment(). This patch introduces the GSO API framework to DPDK.

rte_gso_segment() splits an input packet into small ones in each
invocation. The GSO library refers to these small packets generated
by rte_gso_segment() as GSO segments. Each of the newly-created GSO
segments is organized as a two-segment MBUF, where the first segment is a
standard MBUF, which stores a copy of packet header, and the second is an
indirect MBUF which points to a section of data in the input packet.
rte_gso_segment() reduces the refcnt of the input packet by 1. Therefore,
when all GSO segments are freed, the input packet is freed automatically.
Additionally, since each GSO segment has multiple MBUFs (i.e. 2 MBUFs),
the driver of the interface which the GSO segments are sent to should
support to transmit multi-segment packets.

The GSO framework clears the PKT_TX_TCP_SEG flag for both the input
packet, and all produced GSO segments in the event of success, since
segmentation in hardware is no longer required at that point.
