* [PATCH net-next 09/13] net/mlx5: Add creation flags when adding new flow table
From: Saeed Mahameed @ 2016-11-07 13:14 UTC (permalink / raw)
To: David S. Miller; +Cc: netdev, Or Gerlitz, Hadar Hen-Zion, Saeed Mahameed
In-Reply-To: <1478524488-1377-1-git-send-email-saeedm@mellanox.com>
From: Hadar Hen Zion <hadarh@mellanox.com>
When creating flow tables, allow the caller to specify creation flags.
Currently no flags are used and as such this patch doesn't add any new
functionality.

* [PATCH net-next 07/13] net/mlx5: Move alloc/dealloc encap commands declarations to common header file
From: Saeed Mahameed @ 2016-11-07 13:14 UTC (permalink / raw)
To: David S. Miller; +Cc: netdev, Or Gerlitz, Hadar Hen-Zion, Saeed Mahameed
In-Reply-To: <1478524488-1377-1-git-send-email-saeedm@mellanox.com>
From: Hadar Hen Zion <hadarh@mellanox.com>
The alloc and dealloc encap commands will be used in the mlx5e driver,
as such, declare them in a common header file.
Also, rename the functions: mlx5_cmd_{de}alloc_encap is replaced with
mlx5_encap_{de}alloc.

* [PATCH net-next 10/13] net/mlx5: Support encap id when setting new steering entry
From: Saeed Mahameed @ 2016-11-07 13:14 UTC (permalink / raw)
To: David S. Miller; +Cc: netdev, Or Gerlitz, Hadar Hen-Zion, Saeed Mahameed
In-Reply-To: <1478524488-1377-1-git-send-email-saeedm@mellanox.com>
From: Hadar Hen Zion <hadarh@mellanox.com>
In order to support steering rules which add encapsulation headers,
encap_id parameter is needed.
Add new mlx5_flow_act struct which holds action related parameter:
action, flow_tag and encap_id. Use mlx5_flow_act struct when adding a new
steering rule.
This patch doesn't change any functionality.

* [PATCH net-next 11/13] net/mlx5e: Add TC tunnel release action for SRIOV offloads
From: Saeed Mahameed @ 2016-11-07 13:14 UTC (permalink / raw)
To: David S. Miller; +Cc: netdev, Or Gerlitz, Hadar Hen-Zion, Saeed Mahameed
In-Reply-To: <1478524488-1377-1-git-send-email-saeedm@mellanox.com>
From: Hadar Hen Zion <hadarh@mellanox.com>
Enhance the parsing of offloaded TC rules to set HW matching on outer
(encapsulation) headers.
Parse TC tunnel release action and set it as mlx5 decap action when the
required capabilities are supported.
Signed-off-by: Hadar Hen Zion <hadarh@mellanox.com>

* [PATCH net-next 02/13] flow_dissector: Add enums for encapsulation keys
From: Saeed Mahameed @ 2016-11-07 13:14 UTC (permalink / raw)
To: David S. Miller; +Cc: netdev, Or Gerlitz, Hadar Hen-Zion, Saeed Mahameed
In-Reply-To: <1478524488-1377-1-git-send-email-saeedm@mellanox.com>
From: Hadar Hen Zion <hadarh@mellanox.com>
New encapsulation keys were added to the flower classifier, which allow
classification according to outer (encapsulation) headers attributes
such as key and IP addresses.
In order to expose those attributes outside flower, add
corresponding enums in the flow dissector.

* [PATCH net-next 13/13] net/mlx5e: Add basic TC tunnel set action for SRIOV offloads
From: Saeed Mahameed @ 2016-11-07 13:14 UTC (permalink / raw)
To: David S. Miller; +Cc: netdev, Or Gerlitz, Hadar Hen-Zion, Saeed Mahameed
In-Reply-To: <1478524488-1377-1-git-send-email-saeedm@mellanox.com>
From: Hadar Hen Zion <hadarh@mellanox.com>
In mlx5 HW, encapsulation is offloaded by the steering rule having
index into an encapsulation table containing the entire set of headers
to be added by the HW. The driver sets these headers in a buffer when we
are offloading the action.
The code maintains mlx5_encap_entry for each encap header it has
encountered when attempted to offload TC tunnel set action.
This entry maintains a linked list of all the flows sharing the same
encap header, when the last flow is removed from the list the encap
entry is removed.
The actual encap_header is allocated by the driver in the hardware only
if we have layer two neighbour info when the encap entry is created.
While the flow is in the driver, the driver holds a reference on the
neighbour.
When a new flow with encap action is inserted, the code first checks if
the required encap entry exists according to the tunnel set parameters.
If it does the encap is shared, otherwise a new mlx5_encap_entry is
created.
TC action parsing implementation in the driver assumes that tunnel set
action is provided in the same order set by the user, e.g before the
mirred_redirect action.

* [PATCH net-next 00/13] Mellanox 100G SRIOV offloads tunnel_key set/release
From: Saeed Mahameed @ 2016-11-07 13:14 UTC (permalink / raw)
To: David S. Miller; +Cc: netdev, Or Gerlitz, Hadar Hen-Zion, Saeed Mahameed
Hi Dave,
>From Hadar Hen Zion:
This series further enhances the SRIOV TC offloads of mlx5 to handle the
TC tunnel_key release and set actions.
This serves a common use-case in virtualization systems where the virtual
switch encapsulate packets (tunnel_key set action) sent from VMs with
outer headers corresponding to the local/remote host IPs and de-capsulate
(tunnel_key release) outer headers before the packets are received by the
VM.
We use the new E-Switch switchdev mode and TC tunnel_key set/release
action to achieve that also in SW defined SRIOV environments by
offloading TC rules that contain these actions along with forwarding
(TC mirred/redirect action) the packets.
The first six patches are adding the needed support in flow dissector,
flower and tc for offloading tunnel_key actions:
- The first three patches are adding the needed help functions
and enums
- The next three patches in the series are adding UDP port attribute
to tunnel_key release and set actions.
The addition of UDP ports would allow the HW driver to make sure they are
given (say) a VXLAN tunnel to offload (mlx5e uses that).
Patches 7-10 are mlx5 preparations for tunnel_key actions offloads support.
Patch #11 adds mlx5e support to offload tunnel_key release action, and the
last two patches (#12-13) add mlx5e support to tc tunnel_key set action.
Currently in order to offload tc tunnel_key release action, the tc rule
should be placed on top of the mlx5e offloading (uplink) interface instead
of the shared tunnel interface. The resolution between the tunnel interface
to the HW netdevice will be implemented in a follow up series.
Hadar.
This series was generated against commit
94edc86bf13f ("Merge branch 'dwmac-sti-refactor-cleanup'")
Thanks,
Saeed.

By implementing this ndo, the host stack will set the vxlan udp port
also to VF representor netdevices. This will allow the TC offload code
in the driver when it gets a tunnel key set action to identify the UDP
port as vxlan, and hence the rule will be a candidate for offloading.

* Re: [lkp] [net] af1fee9821: BUG:spinlock_trylock_failure_on_UP_on_CPU

Hi,
I tried to get this "lkp" up and running, but I had some troubles gettting
these scripts to work.
But it seems like it can be reproduced using th eprovided config file, and qemu.
Here is what I did:
# reproduce original bug
git reset --hard af1fee98219992ba2c12441a447719652ed7e983
mkdir bug-build
cp config-4.8.0-14895-gaf1fee9 bug-build/.config
make O=bug-build oldconfig
make O=bug-build -j8
qemu-system-x86_64 -enable-kvm -cpu host -smp 2 -m 4G -kernel \
../net-next/bug-build/arch/x86_64/boot/bzImage -nographic
<see-output-1-below>
# bug seemed to be re-produced
# Try previous version
git reset --hard 32ab0a38f0bd554cc45203ff4fdb6b0fdea6f025
make O=bug-build oldconfig
make O=bug-build -j8
qemu-system-x86_64 -enable-kvm -cpu host -smp 2 -m 4G -kernel \
../net-next/bug-build/arch/x86_64/boot/bzImage -nographic
<see-output-2-below>
# bug seemed to disappear
# Try the buggy revision again - but without MICROSEMI_PHY
git reset --hard af1fee98219992ba2c12441a447719652ed7e983
sed -e "/MICROSEMI_PHY/d" -i bug-build/.config
make O=bug-build oldconfig
cat bug-build/.config | grep MICROSEMI_PHY
qemu-system-x86_64 -enable-kvm -cpu host -smp 2 -m 4G -kernel \
../net-next/bug-build/arch/x86_64/boot/bzImage -nographic
<see-output-3-below>
# bug still seem to be there...
Not sure what this tells me, any hints are more than welcome.
Best regards
Allan W. Nielsen

Hi Andreas/Kristoffer,
Kbuild generated an error for this driver when I exposed the phylib
phy_aneg_done() function in the first version of my patches. For this
driver, I have two choices:
- Remove the phy_aneg_done() function from the aeroflex driver and
have it use the phylib version which is now exported
- Rename the current phy_aneg_done() function in the aeroflex driver
and have the driver continue to use its version.
I think the first option is the way to go, but I don't have a sparc
machine on which to test it. Let me know which you would prefer and
I will include that in the second version of the patch submission.
Thanks,
Tom

* [PATCH net] Fixes: 5943634fc559 ("ipv4: Maintain redirect and PMTU info in struct rtable again.")
From: Stephen Suryaputra Lin @ 2016-11-07 15:04 UTC (permalink / raw)
To: netdev; +Cc: Stephen Suryaputra Lin
ICMP redirects behavior is different after the commit above. An email
requesting the explanation on why the behavior needs to be different
was sent earlier to netdev (https://patchwork.ozlabs.org/patch/687728/).
Since there isn't a reply yet, I decided to prepare this formal patch.
In v2.6 kernel, it used to be that ip_rt_redirect() calls
arp_bind_neighbour() which returns 0 and then the state of the neigh for
the new_gw is checked. If the state isn't valid then the redirected
route is deleted. This behavior is maintained up to v3.5.7 by
check_peer_redirect() because rt->rt_gateway is assigned to
peer->redirect_learned.a4 before calling ipv4_neigh_lookup().
After the commit, ipv4_neigh_lookup() is performed without the
rt_gateway assigned to the new_gw. In the case when rt_gateway (old_gw)
isn't zero, the function uses it as the key. The neigh is most likely valid
since the old_gw is the one that sends the ICMP redirect message. Then the
new_gw is assigned to fib_nh_exception. The problem is: the new_gw ARP may
never gets resolved and the traffic is blackholed.

* [PATCH/RFC net-next] ravb: Add dma_unmap_single in ravb_ring_free
From: Simon Horman @ 2016-11-07 15:27 UTC (permalink / raw)
To: Sergei Shtylyov; +Cc: Magnus Damm, netdev, linux-renesas-soc
From: Kazuya Mizuguchi <kazuya.mizuguchi.ks@renesas.com>
The kernel panic occurs with "swiotlb buffer is full" message
after repeating suspend and resume, because dma_map_single of
ravb_ring_format and ravb_start_xmit is not released.
This patch adds dma_unmap_single in ravb_ring_free, and fixes
its problem.

The Tx path in DPAA requires one to insert a back-pointer to the skb into
the Tx buffer. On the Tx confirmation path the back-pointer in the buffer
is used to release the skb. If Tx buffer is shared we'd alter the back-pointer
and leak/double free skbs. See also

I'll remove the option, udev rules like these can achieve the same effect:
SUBSYSTEM=="net", DRIVERS=="fsl_dpa*", ATTR{device_addr}=="ffe4e0000", NAME="fm1-mac1"
SUBSYSTEM=="net", DRIVERS=="fsl_dpa*", ATTR{device_addr}=="ffe4e2000", NAME="fm1-mac2"

Will address this.

Thank you for your time. I know the dpaa_eth is large, about 4K LOC,
also depends on the in-tree FMan and QMan drivers that are a bit
larger. We're coming down to this from a set of drivers that amounted
to more than 100K LOC and stuff like the ndos that here do nothing are
artifacts of that deep pruning. I'll go through all the code to check
for such redundancies before the next submission but junk is always
easier to see for a fresh pair of eyes.
Thank you,
Madalin

Using ingress information (iif in this case) to determine the route for a response seems appropriate.
I can send a patch to revert back to:
if (!oif && netif_index_is_vrf(net, skb->skb_iif))
oif = skb->skb_iif;
thanks for the report.

Then have your software state store an array of SKB pointers, one for each
TX ring entry, just like every other driver does.
