This patch is to remove the typedef sctp_param_t, and replace with struct sctp_paramhdr in the places where it's using this typedef. It is also to remove the useless declaration sctp_addip_addr_config and fix the lack of params for some other functions' declaration. Signed-off-by:

Simon Horman says: ==================== nfp: introduce flower offload capabilities this series adds flower offload to the NFP driver. It builds on recent work to add representor and a skeleton flower app - now the app does what its name says. In general the approach taken is to allow some flows within the universe of possible flower matches and tc actions to be offloaded. It is planned that this support will grow over time but the support offered by this patch-set seems to be a reasonable starting point. Key Changes since v2: * Revised flow structures to simplify setup/teardown and locking of stats * Addressed other code-change review of v2 Other review questions regarding v2 have been answered on netdev. ==================== Signed-off-by: -

Previously the flower offloads never sends messages to the hardware, and never registers a handler for receiving messages from hardware. This patch enables the flower offloads to send control messages to hardware when adding and removing flow rules. Additionally it registers a control message rx handler for receiving stats updates from hardware for each offloaded flow. Additionally this patch adds 4 control message types; Add, modify and delete flow, as well as flow stats. It also allows nfp_flower_cmsg_get_data() to be used outside of cmsg.c. Signed-off-by:

Previously there was no way of updating flow rule stats after they have been offloaded to hardware. This is solved by keeping track of stats received from hardware and providing this to the TC handler on request. Signed-off-by:

Adds metadata describing the mask id of each flow and keeps track of flows installed in hardware. Previously a flow could not be removed from hardware as there was no way of knowing if that a specific flow was installed. This is solved by storing the offloaded flows in a hash table. Signed-off-by:

Adds a flower based TC offload handler for representor devices, this is in addition to the bpf based offload handler. The changes in this patch will be used in a follow-up patch to add tc flower offload to the NFP. The flower app enables tc offloads on representors by default. Signed-off-by:

Add phys_switch_id support by allowing lookup of SWITCHDEV_ATTR_ID_PORT_PARENT_ID via the nfp_repr_port_attr_get switchdev operation. This is visible to user-space in the phys_switch_id attribute of a netdev. e.g. cd /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 find . -name phys_switch_id | xargs grep . ./net/eth3/phys_switch_id:00154d1300bd ./net/eth4/phys_switch_id:00154d1300bd ./net/eth2/phys_switch_id:00154d1300bd grep: ./net/eth5/phys_switch_id: Operation not supported In the above eth2 and eth3 and representor netdevs for the first and second physical port. eth4 is the representor for the PF. And eth5 is the PF netdev. Signed-off-by:

Add a helper to allow switchdev ops to be set if NET_SWITCHDEV is configured and do nothing otherwise. This allows for slightly cleaner code which uses switchdev but does not select NET_SWITCHDEV. Signed-off-by:

Elena Reshetova says: ==================== v3 net generic subsystem refcount conversions Changes in v3: Rebased on top of the net-next tree. Changes in v2: No changes in patches apart from rebases, but now by default refcount_t = atomic_t (*) and uses all atomic standard operations unless CONFIG_REFCOUNT_FULL is enabled. This is a compromise for the systems that are critical on performance (such as net) and cannot accept even slight delay on the refcounter operations. This series, for core network subsystem components, replaces atomic_t reference counters with the new refcount_t type and API (see include/linux/refcount.h). By doing this we prevent intentional or accidental underflows or overflows that can led to use-after-free vulnerabilities. These patches contain only generic net pieces. Other changes will be sent separately. The patches are fully independent and can be cherry-picked separately. The big patches, such as conversions for sock structure, need a very detailed look from maintainers: refcount managing is quite complex in them and while it seems that they would benefit from the change, extra checking is needed. The biggest corner issue is the fact that refcount_inc() does not increment from zero. If there are no objections to the patches, please merge them via respective trees. * The respective change is currently merged into -next as "locking/refcount: Create unchecked atomic_t implementation". ==================== Signed-off-by: -

This allows to avoid accidental refcounter overflows that might lead to use-after-free situations. This patch uses refcount_inc_not_zero() instead of atomic_inc_not_zero_hint() due to absense of a _hint() version of refcount API. If the hint() version must be used, we might need to revisit API.

Rafal Ozieblo says: ==================== PTP support for macb driver This patch series adds support for PTP synchronization protocol in Cadence GEM driver based on PHC. v2 changes: * removed alarm's support * removed external time stamp support * removed PTP event interrupt handling * removed ptp_hw_support flag * removed all extra sanity checks * removed unnecessary #ifdef * fixed coding style and alligment issues * renamed macb.c to macb_main.c v3 changes: * added checking NULL ptr from ptp_clock_register() * fixed error codes return * locals list in "upside down Christmas tree" style * fixed some other issues from review v4 changes: * respin to the newest next-next (28 Jun 2017) ==================== Signed-off-by: -

This patch is based on original Harini's patch and Andrei's patch, implemented in a separate file to ease the review/maintanance and integration with other platforms. This driver supports GEM-GXL: - Register ptp clock framework - Initialize PTP related registers - HW time stamp on the PTP Ethernet packets are received using the SO_TIMESTAMPING API. Time stamps are obtained from the dma buffer descriptors - add macb_ptp to compilation chain Signed-off-by:
