BUFFER_AVAILABLE interrupt is sent by firmware to indicate change in buffer status. We should check buffer status while handling this interrupt. Currently buffer status is checked only while dequeueing packets. This patch fixes a data traffic stuck problem observed occasionally. Signed-off-by:

We get buffer full event from firmware whenever Tx queue is full Host should stop writing packets after this and resume after buffer free event. Buffer status checking is optimized for once in 4 times if BUFF_FULL condition is not set, otherwise once for every packet. Signed-off-by:

Arkadi Sharshevsky says: ==================== Update DSA's FDB API and perform switchdev cleanup The patchset adds support for configuring static FDB entries via the switchdev notification chain. The current method for FDB configuration uses the switchdev's bridge bypass implementation. In order to support this legacy way and to perform the switchdev cleanup, the implementation is moved inside DSA. The DSA drivers cannot sync the software bridge with hardware learned entries and use the switchdev's implementation of bypass FDB dumping. Because they are the only ones using this functionality, the fdb_dump implementation is moved from switchdev code into DSA. Finally after this changes a major cleanup in switchdev can be done. Please see individual patches for patch specific change logs. v1->v2 - Split MDB/vlan dump removal into core/driver removal. v2->v3 - The self implementation for FDB add/del is moved inside DSA. ==================== Tested-by:

Currently the bridge port flags, vlans, FDBs and MDBs can be offloaded through the bridge code, making the switchdev's SELF bridge bypass implementation to be redundant. This implies several changes: - No need for dump infra in switchdev, DSA's special case is handled privately. - Remove obj_dump from switchdev_ops. - FDBs are removed from obj_add/del routines, due to the fact that they are offloaded through the bridge notification chain. - The switchdev_port_bridge_xx() and switchdev_port_fdb_xx() functions can be removed.

Add support for learning FDB through notification. The driver defers the hardware update via ordered work queue. In case of a successful FDB add a notification is sent back to bridge. In case of hw FDB del failure the static FDB will be deleted from the bridge, thus, the interface is moved to down state in order to indicate inconsistent situation. Signed-off-by:

The prepare phase for FDB add is unneeded because most of DSA devices can have failures during bus transactions (SPI, I2C, etc.), thus, the prepare phase cannot guarantee success of the commit stage.

Quoting Ilan Tayari: 1. Set up a host-to-host IPSec tunnel (or transport, doesn't matter) 2. Ping over IPSec, or do something to populate the pcpu cache 3. Join a MC group, then leave MC group 4. Try to ping again using same CPU as before -> traffic doesn't egress the machine at all Ilan debugged the problem down to the fact that one of the path dsts devices point to lo due to earlier dst_dev_put(). In this case, dst is marked as DEAD and we cannot reuse the bundle. The cache only asserted that the requested policy and that of the cached bundle match, but its not enough - also verify the path is still valid.

Egil Hjelmeland says: ==================== Refactor lan9303_xxx_packet_processing This series is purely non functional. It changes the lan9303_enable_packet_processing, lan9303_disable_packet_processing() to pass port number (0,1,2) as parameter instead of port offset. This aligns them with other functions in the module, and makes it possible to simplify the code. The lan9303_enable_packet_processing, lan9303_disable_packet_processing functions operate on port. Therefore rename the functions to reflect that as well. Reviewer pointed out lan9303_get_ethtool_stats would be better off with the use of a lan9303_read_switch_port(). So that was added to the series. Changes v3 -> v4: - Whitespace adjustments. Changes v2 -> v3: - Patch 1: Removed the change in lan9303_get_ethtool_stats - Added patch 4: rename lan9303_xxx_packet_processing - Added patch 5: refactor lan9303_get_ethtool_stats Changes v1 -> v2: - introduced lan9303_write_switch_port() in first patch - inserted LAN9303_NUM_PORTS patch - Use LAN9303_NUM_PORTS in last patch.

David Lebrun says: ==================== ipv6: sr: add support for advanced local segment processing v2: use EXPORT_SYMBOL_GPL The current implementation of IPv6 SR supports SRH insertion/encapsulation and basic segment endpoint behavior (i.e., processing of an SRH contained in a packet whose active segment (IPv6 DA) is routed to the local node). This behavior simply consists of updating the DA to the next segment and forwarding the packet accordingly. This processing is realised for all such packets, regardless of the active segment. The most recent specifications of IPv6 SR [1] [2] extend the SRH processing features as follows. Each segment endpoint defines a MyLocalSID table. This table maps segments to operations to perform. For each ingress IPv6 packet whose DA is part of a given prefix, the segment endpoint looks up the active segment (i.e., the IPv6 DA) in the MyLocalSID table and applies the corresponding operation. Such specifications enable to specify arbitrary operations besides the basic SRH processing and allow for a more fine-grained classification. This patch series implements those extended specifications by leveraging a new type of lightweight tunnel, seg6local. The MyLocalSID table is simply an arbitrary routing table (using CONFIG_IPV6_MULTIPLE_TABLES). The following commands would assign the prefix fc00::/64 to the MyLocalSID table, map the segment fc00::42 to the regular SRH processing function (named "End"), and drop all packets received with an undefined active segment: ip -6 rule add fc00::/64 lookup 100 ip -6 route add fc00::42 encap seg6local action End dev eth0 table 100 ip -6 route add blackhole default table 100 As another example, the following command would assign the segment fc00::1234 to the regular SRH processing function, except that the processed packet must be forwarded to the next-hop fc42::1 (this operation is named "End.X"): ip -6 route add fc00::1234 encap seg6local action End.X nh6 fc42::1 dev eth0 table 100 Those two basic operations (End and End.X) are defined in [1]. A more extensive list of advanced operations is defined in [2]. The first two patches of the series are preliminary work that remove an assumption about initial SRH format, and export the two functions used to insert and encapsulate an SRH onto packets. The third patch defines the new seg6local lightweight tunnel and implement the core functions. The fourth patch implements the operations needed to handle the newly defined rtnetlink attributes. The fifth patch implements a few SRH processing operations, including End and End.X.

This patch implements the following seg6local actions. - SEG6_LOCAL_ACTION_END: regular SRH processing. The DA of the packet is updated to the next segment and forwarded accordingly. - SEG6_LOCAL_ACTION_END_X: same as above, except that the packet is forwarded to the specified IPv6 next-hop. - SEG6_LOCAL_ACTION_END_DX6: decapsulate the packet and forward to inner IPv6 packet to the specified IPv6 next-hop. - SEG6_LOCAL_ACTION_END_B6: insert the specified SRH directly after the IPv6 header of the packet. - SEG6_LOCAL_ACTION_END_B6_ENCAP: encapsulate the packet within an outer IPv6 header, containing the specified SRH.
