This reverts commit 34c2d9fb. There are 2 reasons for this revert: 1) The commit in question doesn't do what it says it does. The description reads: "Allow bridge forward delay to be configured when Spanning Tree is enabled." This was already the case before the commit was made. What the commit actually do was disallow invalid values or 'forward_delay' when STP was turned off. 2) The above change was actually a change in the user observed behavior and broke things like libvirt and other network configs that set 'forward_delay' to 0 without enabling STP. The value of 0 is actually used when STP is turned off to immediately mark the bridge as forwarding. Signed-off-by:

Arnd Bergmann reported: In my ARM randconfig tests, I'm getting a build error for newly added code in bpf_perf_event_read and bpf_perf_event_output whenever CONFIG_PERF_EVENTS is disabled: kernel/trace/bpf_trace.c: In function 'bpf_perf_event_read': kernel/trace/bpf_trace.c:203:11: error: 'struct perf_event' has no member named 'oncpu' if (event->oncpu != smp_processor_id() || ^ kernel/trace/bpf_trace.c:204:11: error: 'struct perf_event' has no member named 'pmu' event->pmu->count) This can happen when UPROBE_EVENT is enabled but KPROBE_EVENT is disabled. I'm not sure if that is a configuration we care about, otherwise we could prevent this case from occuring by adding Kconfig dependencies. Looking at this further, it's really that UPROBE_EVENT enables PERF_EVENTS. By just having BPF_EVENTS depend on PERF_EVENTS, then all is fine.

The newly added qlogic qed driver uses the zlib library, but misses the dependency: drivers/built-in.o: In function `qed_alloc_stream_mem': drivers/net/ethernet/qlogic/qed/qed_main.c:707: undefined reference to `zlib_inflate_workspacesize' drivers/built-in.o: In function `qed_unzip_data': drivers/net/ethernet/qlogic/qed/qed_main.c:675: undefined reference to `zlib_inflateInit2' This changes Kconfig to always select zlib when needed.

After changing an interface's MTU, then bringing the interface down and back up again, I immediately saw tons of kernel messages like below. The reason for this bad behavior is mvneta_rxq_drop_pkts(), which calls dma_unmap_single() on already-freed memory. So we need to switch the order of those two operations.

The fixed_phy infrastructure is done in a way that is optional, by providing 'static inline' helper functions doing nothing in include/linux/phy_fixed.h for all its APIs. However, three out of the four users (DSA, BCMGENET, and SYSTEMPORT) always 'select FIXED_PHY', presumably because they need that. MVNETA is the fourth one, and if that is built-in but FIXED_PHY is configured as a loadable module, we get a link error: drivers/built-in.o: In function `mvneta_fixed_link_update': fpga-mgr.c:(.text+0x33ed80): undefined reference to `fixed_phy_update_state' Presumably this driver has the same dependency as the others, so this patch also uses 'select' to ensure that the fixed-phy support is built-in.

Since commit 7d5cd2ce529b, when bond_enslave fails on devices that are not ARPHRD_ETHER, if needed, it resets the bonding device back to ARPHRD_ETHER by calling ether_setup. Unfortunately, ether_setup clobbers dev->flags, clearing IFF_UP if the bond device is up, leaving it in a quasi-down state without having actually gone through dev_close. For bonding, if any periodic work queue items are active (miimon, arp_interval, etc), those will remain running, as they are stopped by bond_close. At this point, if the bonding module is unloaded or the bond is deleted, the system will panic when the work function is called. This panic is resolved by calling dev_close on the bond itself prior to calling ether_setup. Cc: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by:

The bonding driver saves a copy of slaves' original mac address and then assigns whatever mac as needed to the slave, depending on mode. In at least modes 5 and 6 (balance-tlb, balance-alb), it often ends up being the mac address of another slave. On release from the bond, the original mac address is supposed to get restored via a dev_set_mac_address() call in the bonding driver's __bond_release_one() function, which calls the slave's ndo_set_mac_address function, which for qlcnic, is qlcnic_set_mac(). Now, this function tries to be somewhat intelligent and exit early if you're trying to set the mac address to the same thing that is already set. The problem here is that adapter->mac_addr isn't in sync with netdev->dev_addr. The qlcnic driver still has the original mac stored in adapter->mac_addr, while the bonding driver has updated netdev->dev_addr, so qlcnic thinks we're trying to set the same address it already has. I think the way to go here, since the function updates both netdev and adapter's stored mac addresses, is to check if either of them doesn't match the newly requested mac. Simply checking netdev's value only could result in a similar mismatch and non-update, so look at both.

Instead of always calling pci_sriov_disable() in remove_one(), the driver should detect whether VFs are currently assigned to the VMs. If the VFs are active in VMs, then it should not disable SRIOV as it is catastrophic to the VMs. Instead, it just leaves the VFs alone and continues to unload the PF. The user can then cleanup the VMs even after the PF driver has been unloaded. Signed-off-by:

There is a race conditions between packet_notifier and packet_bind{_spkt}. It happens if packet_notifier(NETDEV_UNREGISTER) executes between the time packet_bind{_spkt} takes a reference on the new netdevice and the time packet_do_bind sets po->ifindex. In this case the notification can be missed. If this happens during a dev_change_net_namespace this can result in the netdevice to be moved to the new namespace while the packet_sock in the old namespace still holds a reference on it. When the netdevice is later deleted in the new namespace the deletion hangs since the packet_sock is not found in the new namespace' &net->packet.sklist. It can be reproduced with the script below. This patch makes packet_do_bind check again for the presence of the netdevice in the packet_sock's namespace after the synchronize_net in unregister_prot_hook. More in general it also uses the rcu lock for the duration of the bind to stop dev_change_net_namespace/rollback_registered_many from going past the synchronize_net following unlist_netdevice, so that no NETDEV_UNREGISTER notifications can happen on the new netdevice while the bind is executing. In order to do this some code from packet_bind{_spkt} is consolidated into packet_do_dev. import socket, os, time, sys proto=7 realDev='em1' vlanId=400 if len(sys.argv) > 1: vlanId=int(sys.argv[1]) dev='vlan%d' % vlanId os.system('taskset -p 0x10 %d' % os.getpid()) s = socket.socket(socket.PF_PACKET, socket.SOCK_RAW, proto) os.system('ip link add link %s name %s type vlan id %d' % (realDev, dev, vlanId)) os.system('ip netns add dummy') pid=os.fork() if pid == 0: # dev should be moved while packet_do_bind is in synchronize net os.system('taskset -p 0x20000 %d' % os.getpid()) os.system('ip link set %s netns dummy' % dev) os.system('ip netns exec dummy ip link del %s' % dev) s.close() sys.exit(0) time.sleep(.004) try: s.bind(('%s' % dev, proto+1)) except: print 'Could not bind socket' s.close() os.system('ip netns del dummy') sys.exit(0) os.waitpid(pid, 0) s.close() os.system('ip netns del dummy') sys.exit(0) Signed-off-by:Francesco Ruggeri <fruggeri@arista.com> Signed-off-by:

The DSA documentation specifies that each port must be capable of forwarding frames to the CPU port. The last changes on bridging support for the mv88e6xxx driver broke this requirement for non-bridged ports. So as for the bridged ports, reserve a few VLANs (4000+) in the switch to isolate ports that have not been bridged yet. By default, a port will be isolated with the CPU and DSA ports. When the port joins a bridge, it will leave its reserved port. When it is removed from a bridge, it will join its reserved VLAN again.
