This patch fixes a problem of possibly getting inconsistent flow control statuses after a PF reset. Requested_mode was being set with a default value during probing, but the initial HW state could be different from this mode. Change-ID: I772bf07b78616e87086418d4bd87954b66fa17cd Signed-off-by:

Not sure how this compiles at all. Use the correct struct for manipulating the VLAN filter list. Without this, the VLAN filter list doesn't get processed correctly, and VLAN filters will not be re-enabled after any kind of reset. Change-ID: Iceff2dc089f303058fb71ecb08419eed471e0e90 Signed-off-by:

This patch adds a workaround to drop any flow control frames from being transmitted from any VSI. FW can still send flow control frames if flow control is enabled. With this patch in place a malicious VF cannot send flow control or PFC packets out on the wire. Change-ID: I4303b24e98b93066d2767fec24dfe78be591c277 Signed-off-by:

Currently adding a new ipv4 address always cause the creation of the related network route, with default metric. When a host has multiple interfaces on the same network, multiple routes with the same metric are created. If the userspace wants to set specific metric on each routes, i.e. giving better metric to ethernet links in respect to Wi-Fi ones, the network routes must be deleted and recreated, which is error-prone. This patch implements the support for IFA_F_NOPREFIXROUTE for ipv4 address. When an address is added with such flag set, no associated network route is created, no network route is deleted when said IP is gone and it's up to the user space manage such route. Signed-off-by:

Broadcom ethernet driver for the new family of NetXtreme-C/E ethernet devices. v5: - Removed empty blank lines at end of files (noted by David Miller). - Moved busy poll helper functions to bnxt.h to at least make the .c file look less cluttered with #ifdef (noted by Stephen Hemminger). v4: - Broke up 2 long message strings with "\n" (suggested by John Linville) - Constify an array of strings (suggested by Stephen Hemminger) - Improve bnxt_vf_pciid() (suggested by Stephen Hemminger) - Use PCI_VDEVICE() to populate pci_device_id table for more compact source. v3: - Fixed 2 more sparse warnings. - Removed some unused structures in .h files. v2: - Fixed all kbuild test robot reported warnings. - Fixed many of the checkpatch.pl errors and warnings. - Fixed the Kconfig description (noted by Dmitry Kravkov).

Vivien Didelot says: ==================== net: dsa: implement port_fdb_dump in drivers Not all switch chips provide a Get Next kind of operation to dump FDB entries. It is preferred to let the driver handle the dump operation the way it works best for the chip. Thus, drop port_fdb_getnext and implement the port_fdb_dump operation in DSA, which pushes the switchdev FDB dump callback down to the drivers. mv88e6xxx is the only driver affected and is updated accordingly. v3 -> v4: fix rejects on latest net-next v2 -> v3: opencode switchdev_obj_dump_cb_t to avoid multiple typedef; use ether_addr_copy in fdb_dump v1 -> v2: fix a few "return err" instead of "goto unlock" in mv88e6xxx.c ==================== Signed-off-by: -

There is no need to write the MAC address before every Get Next operation, since ATU MAC registers are not cleared between calls. Move the _mv88e6xxx_atu_mac_write call outside of _mv88e6xxx_atu_getnext so future code could call ATU Get Next multiple times and save a few register access. Signed-off-by: -

Alexei Starovoitov says: ==================== bpf_perf_event_output helper Over the last year there were multiple attempts to let eBPF programs output data into perf events by He Kuang and Wangnan. The last one was: https://lkml.org/lkml/2015/7/20/736 It was almost perfect with exception that all bpf programs would sent data into one global perf_event. This patch set takes different approach by letting user space open independent PERF_COUNT_SW_BPF_OUTPUT events, so that program output won't collide. Wangnan is working on corresponding perf patches. ==================== Signed-off-by:

This helper is used to send raw data from eBPF program into special PERF_TYPE_SOFTWARE/PERF_COUNT_SW_BPF_OUTPUT perf_event. User space needs to perf_event_open() it (either for one or all cpus) and store FD into perf_event_array (similar to bpf_perf_event_read() helper) before eBPF program can send data into it. Today the programs triggered by kprobe collect the data and either store it into the maps or print it via bpf_trace_printk() where latter is the debug facility and not suitable to stream the data. This new helper replaces such bpf_trace_printk() usage and allows programs to have dedicated channel into user space for post-processing of the raw data collected. Signed-off-by:

In the ipv4 outbound path of an ipvlan device in l3 mode, the ifindex is being grabbed from dev_get_iflink. This works for the physical device case, since as the documentation of that function notes: "Physical interfaces have the same 'ifindex' and 'iflink' values.". However, if the master device is a veth, and the pairs are in separate net namespaces, the route lookup will fail with -ENODEV due to outer veth pair being in a separate namespace from the ipvlan master/routing namespace. ns0 | ns1 | ns2 veth0a--|--veth0b--|--ipvl0 In ipvlan_process_v4_outbound(), a packet sent from ipvl0 in the above configuration will pass fl.flowi4_oif == veth0a to ip_route_output_flow(), but *net == ns1. Notice also that ipv6 processing is not using iflink. Since there is a discrepancy in usage, fixup both v4 and v6 case to use local dev variable. Tested this with l3 ipvlan on top of veth, as well as with single physical interface in the top namespace. Signed-off-by:

Tom Herbert added SIT support to GRO with commit 19424e05 ("sit: Add gro callbacks to sit_offload"), later reverted by Herbert Xu. The problem came because Tom patch was building GRO packets without proper meta data : If packets were locally delivered, we would not care. But if packets needed to be forwarded, GSO engine was not able to segment individual segments. With the following patch, we correctly set skb->encapsulation and inner network header. We also update gso_type. Tested: Server : netserver modprobe dummy ifconfig dummy0 8.0.0.1 netmask 255.255.255.0 up arp -s 8.0.0.100 4e:32:51:04:47:e5 iptables -I INPUT -s 10.246.7.151 -j TEE --gateway 8.0.0.100 ifconfig sixtofour0 sixtofour0 Link encap:IPv6-in-IPv4 inet6 addr: 2002:af6:798::1/128 Scope:Global inet6 addr: 2002:af6:798::/128 Scope:Global UP RUNNING NOARP MTU:1480 Metric:1 RX packets:411169 errors:0 dropped:0 overruns:0 frame:0 TX packets:409414 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:20319631739 (20.3 GB) TX bytes:29529556 (29.5 MB) Client : netperf -H 2002:af6:798::1 -l 1000 & Checked on server traffic copied on dummy0 and verify segments were properly rebuilt, with proper IP headers, TCP checksums... tcpdump on eth0 shows proper GRO aggregation takes place.

if_nlmsg_size() overestimates the minimum allocation size of netlink dump request (when called from rtnl_calcit()) or the size of the message (when called from rtnl_getlink()). This is because ext_filter_mask is not supported by rtnl_link_get_af_size() and rtnl_link_get_size(). The over-estimation is significant when at least one netdev has many VLANs configured (8 bytes for each configured VLAN). This patch-set "rightsizes" the protocol specific attribute size calculation by propagating ext_filter_mask to rtnl_link_get_af_size() and adding this a argument to get_link_af_size op in rtnl_af_ops. Bridge module already used filtering aware sizing for notifications. br_get_link_af_size_filtered() is consistent with the modified get_link_af_size op so it replaces br_get_link_af_size() in br_af_ops. br_get_link_af_size() becomes unused and thus removed.
