Few cleanups including: bpf_redirect_map() is really XDP only due to the return code. Move it to a more appropriate location where we do the XDP redirect handling and change it's name into bpf_xdp_redirect_map() to make it consistent to the bpf_xdp_redirect() helper. xdp_do_redirect_map() helper can be static since only used out of filter.c file. Drop the goto in xdp_do_generic_redirect() and only return errors directly. In xdp_do_flush_map() only clear ri->map_to_flush which is the arg we're using in that function, ri->map is cleared earlier along with ri->ifindex. Signed-off-by:

Currently, iproute2's BPF ELF loader works fine with array of maps when retrieving the fd from a pinned node and doing a selfcheck against the provided map attributes from the object file, but we fail to do the same for hash of maps and thus refuse to get the map from pinned node. Reason is that when allocating hash of maps, fd_htab_map_alloc() will set the value size to sizeof(void *), and any user space map creation requests are forced to set 4 bytes as value size. Thus, selfcheck will complain about exposed 8 bytes on 64 bit archs vs. 4 bytes from object file as value size. Contract is that fdinfo or BPF_MAP_GET_FD_BY_ID returns the value size used to create the map. Fix it by handling it the same way as we do for array of maps, which means that we leave value size at 4 bytes and in the allocation phase round up value size to 8 bytes. alloc_htab_elem() needs an adjustment in order to copy rounded up 8 bytes due to bpf_fd_htab_map_update_elem() calling into htab_map_update_elem() with the pointer of the map pointer as value. Unlike array of maps where we just xchg(), we're using the generic htab_map_update_elem() callback also used from helper calls, which published the key/value already on return, so we need to ensure to memcpy() the right size.

Antoine Tenart says: ==================== net: mvpp2: MAC/GoP configuration This is based on net-next (e2a7c34f). I removed the GoP interrupt and PHY optional parts in this v2 to ease the review process as the MAC/GoP initialization seemed to start less discussions :) This series now only aims at making the PPv2 driver less depending on the firmware/bootloader initialization. Some patches cleanup some parts as well, and add new interface descriptions in the dt. The current implementation of the PPv2 driver relies on the firmware/bootloader initialization to configure some parts, as the Group of Ports (GoP) and the MACs (GMAC and/or XLG MAC --for 10G--). The drawback is the kernel must be configured to match exactly what the bootloader configures which is not convenient and is an issue when using boards having an Ethernet port and an SFP port wired to the same GoP port, as no dynamic configuration can be done. This series adds the GoP and GMAC/XLG MAC initializations so that the PPV2 does not have to rely on a previous initialization. One part is still missing from this series, and that would be the 'comphy' which provides shared serdes PHYs and which must be configured as well for a full kernel initialization to work. This comphy support will be part of a following up series. (This series was also tested with this 'comphy' support, as it's nearly ready). @Dave: patches 9 and 10 should go through the mvebu tree. Thanks! ==================== Signed-off-by:

This adds a routine to initialize the XLG MAC at the port level when using a port and the XAUI/10GKR interface mode. This wasn't done until this commit, and the mvpp2 driver was relying on the bootloader/firmware initialization. This doesn't mean everything is configured in the mvpp2 driver now, but it helps reducing the gap. Signed-off-by:

The patch adds ERSPAN type II tunnel support. The implementation is based on the draft at [1]. One of the purposes is for Linux box to be able to receive ERSPAN monitoring traffic sent from the Cisco switch, by creating a ERSPAN tunnel device. In addition, the patch also adds ERSPAN TX, so Linux virtual switch can redirect monitored traffic to the ERSPAN tunnel device. The traffic will be encapsulated into ERSPAN and sent out. The implementation reuses tunnel key as ERSPAN session ID, and field 'erspan' as ERSPAN Index fields: ./ip link add dev ers11 type erspan seq key 100 erspan 123 \ local 172.16.1.200 remote 172.16.1.100 To use the above device as ERSPAN receiver, configure Nexus 5000 switch as below: monitor session 100 type erspan-source erspan-id 123 vrf default destination ip 172.16.1.200 source interface Ethernet1/11 both source interface Ethernet1/12 both no shut monitor erspan origin ip-address 172.16.1.100 global [1] https://tools.ietf.org/html/draft-foschiano-erspan-01 [2] iproute2 patch: http://marc.info/?l=linux-netdev&m=150306086924951&w=2 [3] test script: http://marc.info/?l=linux-netdev&m=150231021807304&w=2Signed-off-by:

UDP over IPv4 and v6 can be set differently. The default hash level is L4. We currently only allow switching TX hash level from within the guests. The ethtool callback function is triggered by command line, and update the per device variables of the hash level. On Azure, fragmented UDP packets is not yet supported with L4 hashing, and may have high packet loss rate. Using L3 hashing is recommended in this case. This ethtool option allows a user to make this selection. ==================== Signed-off-by: -
