* [PATCH net-next 3/6] net: aquantia: add support of L3/L4 ntuple filters
From: Igor Russkikh @ 2018-11-12 15:03 UTC (permalink / raw)
  To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542034379.git.igor.russkikh@aquantia.com>

From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>

Add support of L3/L4 5-tuple {protocol, src-ip, dst-ip, src-port, dst-port}
filters. Mask is not supported. Src-port and dst-port are only compared for
TCP/UDP/SCTP packets. Both IPv4 and IPv6 are supported.
The supported actions are the drop and the queue assignment.
Due to fixed order of the rules in the NIC, the location 32-39 are
reserved for L3/L4 5-tuple filters. The locations 32 and 36 are
reserved for IPv6 filters.

Examples:
sudo ethtool -N eth0 flow-type ip6 src-ip 2001:db8:0:f101::2 \
dst-ip 2001:db8:0:f101::5 action -1 loc 36

sudo ethtool -N eth0 flow-type udp4 src-ip 10.0.0.4 \
dst-ip 10.0.0.7 src-port 2000 dst-port 2001 action 2 loc 32

* [PATCH net-next 4/6] net: aquantia: add vlan id to rx flow filters
From: Igor Russkikh @ 2018-11-12 15:03 UTC (permalink / raw)
  To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542034379.git.igor.russkikh@aquantia.com>

From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>

The VLAN filter (VLAN id) is compared against 16 filters.
VLAN id must be accompanied by mask 0xF000. That is to distinguish
VLAN filter from L2 Ethertype filter with UserPriority since both
User Priority and VLAN ID are passed in the same 'vlan' parameter.
Flow type may be any as  it is not matched for VLAN filter.
Due to fixed order of the rules in the NIC, the location 0-15 are
reserved for vlan filters.

Example:
To add a rule that directs packets from VLAN 2001 to queue 5:
ethtool -N <ethX> flow-type ip4 vlan 2001 m 0xF000 action 5 loc 0

* [PATCH net-next 5/6] net: aquantia: add ethertype and PCP to rx flow filters
From: Igor Russkikh @ 2018-11-12 15:03 UTC (permalink / raw)
  To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542034379.git.igor.russkikh@aquantia.com>

From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>

L2 EtherType filters allows to filter packet by EtherType field or
both EtherType and User Priority (PCP) field of 802.1Q.
UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That
is to distinguish VLAN filter from L2 Ethertype filter with
UserPriority since both User Priority and VLAN ID are passed in the
same 'vlan' parameter.

Example:
To add a filter that directs IP4 packess of priority 3 to queue 3:
ethtool -N <ethX> flow-type ether proto 0x800 vlan 0x600 m 0x1FFF \
action 3 loc 16

* [PATCH net-next 6/6] net: aquantia: add support of rx-vlan-filter offload
From: Igor Russkikh @ 2018-11-12 15:03 UTC (permalink / raw)
  To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542034379.git.igor.russkikh@aquantia.com>

From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>

Since it uses the same NIC table as rx flow vlan filter therefore
rx-flow vlan filter accepts only vlans that present on the interface
in case of rx-vlan-filter is on.

Hi David, please discard the patch, it seems it gets a conflict with just integrated 'net' tree.

Will resend it shortly.

Sorry for this.

* [PATCH net-next v2 0/6] net: aquantia: add rx-flow filter support
From: Igor Russkikh @ 2018-11-12 15:45 UTC (permalink / raw)
  To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh

In this patchset the rx-flow filters functionality and vlan filter offloads
are implemented.

The rules in NIC hardware have fixed order and priorities.
To support this, the locations of filters from ethtool perspective are also fixed:

* Locations 0 - 15 for VLAN ID filters
* Locations 16 - 31 for L2 EtherType and PCP filters
* Locations 32 - 39 for L3/L4 5-tuple filters (locations 32, 36 for IPv6)

Dmitry Bogdanov (6):
  net: aquantia: add rx-flow filter definitions
  net: aquantia: add infrastructure for ntuple rules
  net: aquantia: add support of L3/L4 ntuple filters
  net: aquantia: add vlan id to rx flow filters
  net: aquantia: add ethertype and PCP to rx flow filters
  net: aquantia: add support of rx-vlan-filter offload

* [PATCH net-next v2 3/6] net: aquantia: add support of L3/L4 ntuple filters
From: Igor Russkikh @ 2018-11-12 15:46 UTC (permalink / raw)
  To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542037157.git.igor.russkikh@aquantia.com>

From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>

Add support of L3/L4 5-tuple {protocol, src-ip, dst-ip, src-port, dst-port}
filters. Mask is not supported. Src-port and dst-port are only compared for
TCP/UDP/SCTP packets. Both IPv4 and IPv6 are supported.
The supported actions are the drop and the queue assignment.
Due to fixed order of the rules in the NIC, the location 32-39 are
reserved for L3/L4 5-tuple filters. The locations 32 and 36 are
reserved for IPv6 filters.

Examples:
sudo ethtool -N eth0 flow-type ip6 src-ip 2001:db8:0:f101::2 \
dst-ip 2001:db8:0:f101::5 action -1 loc 36

sudo ethtool -N eth0 flow-type udp4 src-ip 10.0.0.4 \
dst-ip 10.0.0.7 src-port 2000 dst-port 2001 action 2 loc 32

* [PATCH net-next v2 4/6] net: aquantia: add vlan id to rx flow filters
From: Igor Russkikh @ 2018-11-12 15:46 UTC (permalink / raw)
  To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542037157.git.igor.russkikh@aquantia.com>

From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>

The VLAN filter (VLAN id) is compared against 16 filters.
VLAN id must be accompanied by mask 0xF000. That is to distinguish
VLAN filter from L2 Ethertype filter with UserPriority since both
User Priority and VLAN ID are passed in the same 'vlan' parameter.
Flow type may be any as  it is not matched for VLAN filter.
Due to fixed order of the rules in the NIC, the location 0-15 are
reserved for vlan filters.

Example:
To add a rule that directs packets from VLAN 2001 to queue 5:
ethtool -N <ethX> flow-type ip4 vlan 2001 m 0xF000 action 5 loc 0

* [PATCH net-next v2 5/6] net: aquantia: add ethertype and PCP to rx flow filters
From: Igor Russkikh @ 2018-11-12 15:46 UTC (permalink / raw)
  To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542037157.git.igor.russkikh@aquantia.com>

From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>

L2 EtherType filters allows to filter packet by EtherType field or
both EtherType and User Priority (PCP) field of 802.1Q.
UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That
is to distinguish VLAN filter from L2 Ethertype filter with
UserPriority since both User Priority and VLAN ID are passed in the
same 'vlan' parameter.

Example:
To add a filter that directs IP4 packess of priority 3 to queue 3:
ethtool -N <ethX> flow-type ether proto 0x800 vlan 0x600 m 0x1FFF \
action 3 loc 16

* [PATCH net-next v2 6/6] net: aquantia: add support of rx-vlan-filter offload
From: Igor Russkikh @ 2018-11-12 15:46 UTC (permalink / raw)
  To: David S . Miller; +Cc: netdev@vger.kernel.org, Igor Russkikh, Dmitry Bogdanov
In-Reply-To: <cover.1542037157.git.igor.russkikh@aquantia.com>

From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>

Since it uses the same NIC table as rx flow vlan filter therefore
rx-flow vlan filter accepts only vlans that present on the interface
in case of rx-vlan-filter is on.

* [PATCH net 1/5] net/smc: abort CLC connection in smc_release
From: Ursula Braun @ 2018-11-12 16:01 UTC (permalink / raw)
  To: davem; +Cc: netdev, linux-s390, schwidefsky, heiko.carstens, raspl, ubraun
In-Reply-To: <20181112160133.16058-1-ubraun@linux.ibm.com>

From: Hans Wippel <hwippel@linux.ibm.com>

In case of a non-blocking SMC socket, the initial CLC handshake is
performed over a blocking TCP connection in a worker. If the SMC socket
is released, smc_release has to wait for the blocking CLC socket
operations (e.g., kernel_connect) inside the worker.

This patch aborts a CLC connection when the respective non-blocking SMC
socket is released to avoid waiting on socket operations or timeouts.

* [PATCH net 4/5] net/smc: atomic SMCD cursor handling

  To: davem; +Cc: netdev, linux-s390, schwidefsky, heiko.carstens, raspl, ubraun
In-Reply-To: <20181112160133.16058-1-ubraun@linux.ibm.com>

Running uperf tests with SMCD on LPARs results in corrupted cursors.
SMCD cursors should be treated atomically to fix cursor corruption.

* [PATCH net 5/5] net/smc: use after free fix in smc_wr_tx_put_slot()

In-Reply-To: <20181112160133.16058-1-ubraun@linux.ibm.com>

From: Ursula Braun <ursula.braun@linux.ibm.com>

In smc_wr_tx_put_slot() field pend->idx is used after being
cleared. That means always idx 0 is cleared in the wr_tx_mask.
This results in a broken administration of available WR send
payload buffers.

From: Karsten Graul <kgraul@linux.ibm.com>

When searching for an existing link group the queue pair number is also
to be taken into consideration. When the SMC server sends a new number
in a CLC packet (keeping all other values equal) then a new link group
is to be created on the SMC client side.

* [PATCH net 3/5] net/smc: add SMC-D shutdown signal
From: Ursula Braun @ 2018-11-12 16:01 UTC (permalink / raw)
  To: davem; +Cc: netdev, linux-s390, schwidefsky, heiko.carstens, raspl, ubraun
In-Reply-To: <20181112160133.16058-1-ubraun@linux.ibm.com>

From: Hans Wippel <hwippel@linux.ibm.com>

When a SMC-D link group is freed, a shutdown signal should be sent to
the peer to indicate that the link group is invalid. This patch adds the
shutdown signal to the SMC code.

* [PATCH net 1/1] s390/ism: clear dmbe_mask bit before SMC IRQ handling
From: Ursula Braun @ 2018-11-12 16:06 UTC (permalink / raw)
  To: davem; +Cc: netdev, linux-s390, schwidefsky, heiko.carstens, raspl, ubraun

SMC-D stress workload showed connection stalls. Since the firmware
decides to skip raising an interrupt if the SBA DMBE mask bit is
still set, this SBA DMBE mask bit should be cleared before the
IRQ handling in the SMC code runs. Otherwise there are small windows
possible with missing interrupts for incoming data.
SMC-D currently does not care about the old value of the SBA DMBE
mask.

* [PATCH net-next 0/4] sctp: add subscribe per asoc and sockopt SCTP_EVENT
From: Xin Long @ 2018-11-12 16:26 UTC (permalink / raw)
  To: network dev, linux-sctp; +Cc: Marcelo Ricardo Leitner, Neil Horman, davem

This patchset mainly adds the Event Subscription sockopt described in
rfc6525#section-6.2:

Subscribing to events as described in [RFC6458] uses a setsockopt()
call with the SCTP_EVENT socket option.  This option takes the
following structure, which specifies the association, the event type
(using the same value found in the event type field), and an on/off
boolean.

  struct sctp_event {
    sctp_assoc_t se_assoc_id;
    uint16_t     se_type;
    uint8_t      se_on;
  };

The user fills in the se_type field with the same value found in the
strreset_type field, i.e., SCTP_STREAM_RESET_EVENT.  The user will
also fill in the se_assoc_id field with either the association to set
this event on (this field is ignored for one-to-one style sockets) or
one of the reserved constant values defined in [RFC6458].  Finally,
the se_on field is set with a 1 to enable the event or a 0 to disable
the event.

As for the old SCTP_EVENTS Option with struct sctp_event_subscribe,
it's being DEPRECATED.

Xin Long (4):
  sctp: define subscribe in sctp_sock as __u16
  sctp: add subscribe per asoc
  sctp: rename enum sctp_event to sctp_event_type
  sctp: add sockopt SCTP_EVENT

sctp_event is a structure name defined in RFC for sockopt
SCTP_EVENT. To avoid the conflict, rename it.

* [PATCH iproute2] testsuite: colorize test result output
From: Stephen Hemminger @ 2018-11-12 16:39 UTC (permalink / raw)
  To: netdev; +Cc: Stephen Hemminger

When running testsuite it is easy as a human to miss failure.
Add symbol colorizing to SKIPED/PASS/FAIL output.
