2019-04-16bpf: add map helper functions push, pop, peek in more BPF programsAlban Crequy1-0/+6
commit f1a2e44a3aec ("bpf: add queue and stack maps") introduced new BPF helper functions: - BPF_FUNC_map_push_elem - BPF_FUNC_map_pop_elem - BPF_FUNC_map_peek_elem but they were made available only for network BPF programs. This patch makes them available for tracepoint, cgroup and lirc programs.

2019-04-12xen-netback: add reference from xenvif to backend_info to facilitate ↵Dongli Zhang2-16/+19
coredump analysis During coredump analysis, it is not easy to obtain the address of backend_info in xen-netback. So far there are two ways to obtain backend_info: 1. Do what xenbus_device_find() does for vmcore to find the xenbus_device and then derive it from dev_get_drvdata(). 2. Extract backend_info from callstack of xenwatch (e.g., netback_remove() or frontend_changed()). This patch adds a reference from xenvif to backend_info so that it would be much more easier to obtain backend_info during coredump analysis.

2019-04-08qmi_wwan: Add quirk for Quectel dynamic configKristian Evensen1-34/+31
Most, if not all, Quectel devices use dynamic interface numbers, and users are able to change the USB configuration at will. Matching on for example interface number is therefore not possible. Instead, the QMI device can be identified by looking at the interface class, subclass and protocol (all 0xff), as well as the number of endpoints. The reason we need to look at the number of endpoints, is that the diagnostic port interface has the same class, subclass and protocol as QMI. However, the diagnostic port only has two endpoints, while QMI has three. Until now, we have identified the QMI device by combining a match on class, subclass and protocol, with a call to the function quectel_diag_detect(). In quectel_diag_detect(), we check if the number of endpoints matches for known Quectel vendor/product ids. Adding new vendor/product ids to quectel_diag_detect() is not a good long-term solution. This commit replaces the function with a quirk, and applies the quirk to affected Quectel devices that I have been able to test the change with (EP06, EM12 and EC25). If the quirk is set and the number of endpoints equal two, we return from qmi_wwan_probe() with -ENODEV.

The poll condition should only check response_length, because reads should only be issued if there is data to read. The response_read flag only prevents double writes. The problem was that the write set the response_read to false, enqued a tpm job, and returned. Then application called poll which checked the response_read flag and returned EPOLLIN. Then the application called read, but got nothing. After all that the async_work kicked in. Added also mutex_lock around the poll check to prevent other possible race conditions.

2019-04-08ipv4: Add helpers for neigh lookup for nexthopDavid Ahern1-6/+4
A common theme in the output path is looking up a neigh entry for a nexthop, either the gateway in an rtable or a fallback to the daddr in the skb: nexthop = (__force u32)rt_nexthop(rt, ip_hdr(skb)->daddr); neigh = __ipv4_neigh_lookup_noref(dev, nexthop); if (unlikely(!neigh)) neigh = __neigh_create(&arp_tbl, &nexthop, dev, false); To allow the nexthop to be an IPv6 address we need to consider the family of the nexthop and then call __ipv{4,6}_neigh_lookup_noref based on it. To make this simpler, add a ip_neigh_gw4 helper similar to ip_neigh_gw6 added in an earlier patch which handles: neigh = __ipv4_neigh_lookup_noref(dev, nexthop); if (unlikely(!neigh)) neigh = __neigh_create(&arp_tbl, &nexthop, dev, false); And then add a second one, ip_neigh_for_gw, that calls either ip_neigh_gw4 or ip_neigh_gw6 based on the address family of the gateway. Update the output paths in the VRF driver and core v4 code to use ip_neigh_for_gw simplifying the family based lookup and making both ready for a v6 nexthop. ipv4_neigh_lookup has a different need - the potential to resolve a passed in address in addition to any gateway in the rtable or skb. Since this is a one-off, add ip_neigh_gw4 and ip_neigh_gw6 diectly. The difference between __neigh_create used by the helpers and neigh_create called by ipv4_neigh_lookup is taking a refcount, so add rcu_read_lock_bh and bump the refcnt on the neigh entry.

2019-04-08neighbor: Add skip_cache argument to neigh_outputDavid Ahern1-2/+2
A later patch allows an IPv6 gateway with an IPv4 route. The neighbor entry will exist in the v6 ndisc table and the cached header will contain the ipv6 protocol which is wrong for an IPv4 packet. For an IPv4 packet to use the v6 neighbor entry, neigh_output needs to skip the cached header and just use the output callback for the neigh entry. A future patchset can look at expanding the hh_cache to handle 2 protocols. For now, IPv6 gateways with an IPv4 route will take the extra overhead of generating the header.

2019-04-08net: xilinx: emaclite: add minimal ndo_do_ioctl hookAlexandru Ardelean1-0/+17
This hook only implements a minimal set of ioctl hooks to be able to access MII regs by using phytool. When using this simple MAC controller, it's pretty difficult to do debugging of the PHY chip without checking MII regs.

2019-04-08net: xilinx: emaclite: add minimal ethtool opsAlexandru Ardelean1-0/+23
This set adds a minimal set of ethtool hooks to the driver, which provide a decent amount of link information via ethtool. With this change, running `ethtool ethX` in user-space provides all the neatly-formatted information about the link (what was negotiated, what is advertised, etc).

2019-04-07net: vrf: Fix ping failed when vrf mtu is set to 0Miaohe Lin1-2/+6
When the mtu of a vrf device is set to 0, it would cause ping failed. So I think we should limit vrf mtu in a reasonable range to solve this problem. I set dev->min_mtu to IPV6_MIN_MTU, so it will works for both ipv4 and ipv6. And if dev->max_mtu still be 0 can be confusing, so I set dev->max_mtu to ETH_MAX_MTU. Here is the reproduce step: 1.Config vrf interface and set mtu to 0: 3: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master vrf1 state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:9e:dd:c1 brd ff:ff:ff:ff:ff:ff 2.Ping peer: 3: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master vrf1 state UP group default qlen 1000 link/ether 52:54:00:9e:dd:c1 brd ff:ff:ff:ff:ff:ff inet 10.0.0.1/16 scope global enp4s0 valid_lft forever preferred_lft forever connect: Network is unreachable 3.Set mtu to default value, ping works: PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data. 64 bytes from 10.0.0.2: icmp_seq=1 ttl=64 time=1.88 ms Fixes: ad49bc6361ca2 ("net: vrf: remove MTU limits for vrf device") Signed-off-by: Miaohe Lin <linmiaohe@huawei.com> Reviewed-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.
